Description

CONDUCTOR

5 The invention relates to woodworking, carpentry and furniture production, in particular, to conductor devices, and can be used for drilling holes in the ends and lateral surfaces of parts primarily for installing connecting elements of structures such as dowels or screed. ιо Several jig devices are known, represented by the following patents: US2740308, US2796778, US2804788, which include a base surface, from which the distance to the hole axis, the base and the clamping mechanism for fixing the part during its processing are counted. These devices are intended mainly for

15 drilling of one hole or several holes, but one diameter, at the same time the clamp acts directly on the surface of the part. In addition, each time the workpiece is replaced, it is necessary to re-set the drilling parameters each time. While in joinery, it is often necessary to manufacture several parts with the same

20 by a set of the number and diameter of the holes (drilling parameters).

There are special machines for drilling holes at any part location. They are intended mainly for mass production, and are of considerable size and weight, relatively expensive and require special maintenance. At the same time, virtually absent

25 similar devices that could be used by small businesses in this area, and which combine the technical capabilities of stationary machines with compactness, ease of setup and portability. Closest to the claimed device to the technical nature of the zo is an invention represented by the patent US2778251. The disadvantage of this technical solution is that the based surface and the base are rigidly interconnected and the support is stationary, which imposes restrictions on the size of the workpiece, the contact is in contact with the surface at one point, therefore, the reliability of fastening is insufficient for large parts (for example, furniture panels) ), there is no installation of the required distance from the edge of the part to the axis of the first hole. In addition, in one operation, only one diameter holes are drilled in the workpiece, and when drilling different holes (for example, for the dowel and the coupler at the same time), several settings of the conductor are required. The technical result of the invention is the variability of the number and diameters of the holes for each workpiece; constant setting of the settings of the conductor mechanisms for any number of blanks with the same set of drilling parameters; reading the distance from the axes of the conductor sleeves with the required technological accuracy not only in width but also in length from the edge of the workpiece; reliable fixation of the workpiece to prevent damage to the surface decor. The achievement of this technical result will lead to an increase in the functionality of the conductor in the serial processing of parts of different, including large, sizes (for example, furniture panels), while maintaining its compactness and portability, as well as efficiency in changing the processed blanks.

The technical result is achieved in that the main components of the conductor — based, clamping and base — are made in the form of profiles, preferably angled, with a certain original interposition of surfaces, and the base profile and the base with a pressing mechanism are consoles parallel to the corresponding planes relative to each other to set the required distance between them depending on the thickness of the workpiece, and the conductor sleeves are placed directly on the grounds of a plane - a shelf sleeves over these consoles. In other words, the clamping mechanism is placed on the corresponding surface of the base parallel to the plane of the axes of the sleeves and perpendicular to the shelf of the sleeves of the base; additionally placed perpendicular to the clamping surface in thickness and parallel to the shelf of the base sleeves, a based surface in depth, and the clamping surface is additionally connected perpendicularly along the entire length with a stiffener, the surface of the clamping mechanism and the shelf of the sleeves are rigidly connected to each other and form the base profile that bases the depth surfaces and the thickness are rigidly interconnected and constitute a based profile, and the rigidly connected pressure surface and stiffener constitute clamping profile also of conductor sleeve placed directly on one of the planes of the base profile, which, in turn, further provided with means for measuring the distance from the workpiece end face to the axis of the first hole. The basing profile is connected to the base by means of at least two fixing fastening elements located along the entire profile length for reliable fixation of the workpiece and the basing surface when drilling, and the working surfaces of the presser and basing profiles are equipped with anti-slip pads to prevent damage to the decorative finish of the workpiece.

The base profile has the ability to move perpendicular to the drilling axis when setting the distance from the clamping surface to the axis mentioned, due to the fact that the base has through oval holes for fasteners. The drawings depict the following:

Figure 4 presents a section along the axis A - A, in which three main profiles are visible, the relative position of which underlies the principle of the conductor: base profile (1), base profile (2), pressure profile (3), which consist of the following surfaces: depth based surface (4); thickness based surface (5); sleeve regiment (6); surface of the clamping mechanism (7); clamping surface (8); stiffener (9); and also: the workpiece (10); friction anti-slip pads (11); oval-shaped holes (12) for the passage of the drill at any position of the base profile. The basement surface in depth, which is shown in section B - B - Fig. 5, is used to set the distance along the drilling axis. A gasket (13) with fixing screws (14) is fastened to it, which presses the base surface in depth to the shelf of the bushes (6). Screws (15) are used to fasten the gasket on the surface. The screws (14) pass through the oval holes (16). The mentioned gasket (13) provides a gap between the shelf of the sleeves and the base surface in depth to remove chips in the drilling process.

Figure 6 shows in section along the axis C - C based surface thickness, the shelf of the sleeves, the surface of the clamping mechanism. thickness, shelf sleeves, the surface of the clamping mechanism. The base surface in thickness (5) is designed to set the drilling axis (axis of the sleeves) along a given axis of the end surface of the workpiece, depending on its thickness. For this purpose, there are two brackets (17) with the adjusting screw (18) located on the indicated surface (5) shown in Fig. 7 - view D of the section C - C, which changes the distance to the axis of the sleeves from the clamping surface. The fastening of the brackets mentioned above are screws (19). On the shelf of the sleeves (6) there are conductor sleeves (20), which are fixed with nuts (21), the aforementioned oval holes (16), threaded sleeve (22) with a locking screw (23) for screwing in the adjusting screw (18). The distance between the conductor sleeves is determined by the standard adopted for this area of woodworking (for furniture production 32 mm). The surface of the clamping mechanism (clamp) (7) contains a bracket (24) for mounting an eccentric (25) on an axis (26) with a lock washer (27). On the eccentric (25) the handle (28) of the clamp lever is attached. Figure 10 - section G - G - shows the clamping mechanism in action. The bracket (24) is mounted on the surface (7) with screws (29). The eccentric (25) interacts with the clamping screw (30), which through the sleeve (31) transfers the force from the clamp lever to the clamping surface (8). To bring the clamping mechanism to its original position, there is a return unit (32) consisting of a screw with a nut and a lock washer and a spring abutting one end against the surface of the clamping mechanism, the other - into a lock washer with a nut. When turning the handle (28) of the pressure lever, due to the interaction of the eccentric (25), pressure screw (30) and pressure surface (8), the gap between this pressure surface and the clamping surface (5) changes. On the surface of the clamping mechanism is fixed by means of a bracket (33) means for measuring the distance, which may be a rod (34) with a pointer (35), which serves to set the distance from the edge of the part to the axis of the first hole along the length of the workpiece. Countdown given edge of the part to the axis of the first hole along the length of the workpiece. This distance is calculated along a ruler (36) with divisions, which is fastened with screws (37). At the other end of the rod, the stop assembly is fixed, shown in FIG. 9, section F - F. The stop assembly is the stop itself (38) and the locking mechanism located in its cavity, which consists of a ball (39) in a recess (40) of the rod axis (34), resting against said spring ball (41) and spring compressing screw (42).

To fix the set distance from the edge of the workpiece to the axis of the conductor hole, use a stopper (43), which can be made in the form of a screw.

Fig. 8 shows (section view E C - C) as the distance from the edge of the part to the common axis of the holes in thickness is measured by a ruler (44), which is attached to the base surface by depth (4) with screws (45). The rib (9) is designed for uniform distribution of the clamping force over the entire plane of the clamp. The bracket (46), which is fastened with screws (47), is a guide for the clamping mechanism. A step screw (48) is screwed into the bracket (46) with a washer (49), which act as guides for the clamping mechanism.

Figure 11 shows how the workpiece (10), intended for drilling holes in it, is placed between the base surface in thickness (5) and the pressure surface (8) using anti-slip pads (11). The possibility of processing parts with different thickness, namely the installation of the axis of the sleeves along a given axis of drilling at the end of the part, provides an oval shape of the holes (16). Adjusting shims (55), ensuring the fixing of blanks of different thickness, are fastened with screws (56) - FIG. 10. Using the adjusting screw (18) with loosening and subsequent fixation of the screw (23), the distance to the drilling axis from the surface (5) is set according to the thickness of the part. Visual control is performed on the ruler (44). The longitudinal position of the workpiece in the conductor on the one hand is limited to the stop (38), and along the ruler (36) the required distance from this edge of the workpiece to the axes of the intended holes is counted, taking into account the pitch the edges of the workpiece to the axes of the planned holes, taking into account the spacing of the conductor sleeves (20), the combination of which is pre-selected depending on the diameters of the produced holes. By turning the presser lever (28) through the eccentric (25) and the presser screw (30), the presser surface (8) is moved and the workpiece is securely fixed throughout the entire plane of the presser. Depending on the thickness of the workpiece, a certain number of adjusting shims (55) are selected, which are fixed with screws (56). With the help of a drill, the required number of holes is drilled, then by turning the lever (28) back, the machined part is released, similar fixing and drilling of the holes in the next part is performed, all necessary current settings of the conductor (in thickness and length of the workpiece) are maintained until there is no need to change them when changing the parameters of the drilling operation. On Fig, 13 shows the applications of the inventive conductor in the carpentry (furniture) production, both for drilling a series of identical holes (for example, for a standard dowel - Fig. 12), and for drilling a combination of different holes with one-time installation of the conductor mechanisms (for example, under shkant and coupler - Fig. 13). In this case, the following notation is entered: (50) - drill; (51) - hole for shkant; (52) - shkant; (53) - hole for the coupler; (54) - coupler, respectively. To limit the depth of drilling is the appropriate limiter (57), which is fixed directly on the drill.
