Definitions
- the invention relates to a grinding shoe, in particular for grinding uneven surfaces with a holding part having a connection to a pressure or vacuum source and an abrasive-carrying sleeve connected to the holding part, at least partially is flexible.
- An abrasive load-bearing flexible sleeve allows the sanding pad to be adapted to the surface of the object to be processed.
- abrasive Sanding shoe By moving the abrasive Sanding shoe, abrasive elements of the abrasive wear part of the surface from.
- the Texture, for example roughness, of the machined surface can be varied.
- a grinding shoe of the type mentioned is known for example from DE 299 00 183 U1, which has a holding part provided with a connection to an air pressure pressure source.
- a holding part With the holding part is a sleeve carrying an abrasive, in particular an air abrasive pad connected, which is at least partially flexible.
- the connection between the The sleeve and the abrasive are made, for example, by means of Velcro or through a other detachable connection. So that the grinding shape is temporarily retained for the grinding process remains, the casing has cast-in steel strips and is consolidated using compressed air. Uneven surfaces can advantageously be machined without great expenditure of time and effort become. Furthermore, the application of different, to the different, is unnecessary Geometry of adapted grinding shoes.
- the shell provided with steel strips has a disadvantageous effect. On the one hand, it exhibits a limited Adaptability and on the other hand, such a well-known training affects the shell negatively affects the economy in the production of the same.
- the user must have a sufficiently strong source of compressed air to carry a relative ensure easy handling of the sanding pad. Otherwise there is a precise adjustment not guaranteed to the surface of the object to be processed.
- the high air pressure in the casing in particular air cushions, worsens the decoupling between holding part and abrasive, which places a considerable burden on the user through the grinding movement of the grinding shoe.
- this coupling between the holding part and the abrasive has an adverse effect.
- the present invention has for its object to provide a grinding shoe, the adapts precisely to the surface of an object to be processed, simply in handling and also economical to manufacture.
- the object is achieved in that the shell is partially, as bulk material existing solid particles is filled.
- the volume of the solid particles and / or the Density of the solid particles can be varied.
- the solid particles present as bulk material ensure a flow of solid particles in the shell and thus a precise Adapting the shell filled with the solid particles to the surface.
- this arrangement enables the envelope to be vacuumed. Through the connection air is sucked out of the shell by means of a vacuum source. Thereby increase the existing between the individual solid particles and the previously set shape remains almost unchanged.
- the grinding shoe is flexible again.
- the strength of the shape of the sanding pad can be controlled, for example, by the amount of negative pressure in the casing.
- the inventive method has proven to be particularly useful for grinding profiled surfaces Solution as beneficial.
- the solid particles are advantageously cube-shaped or spherical to form a To facilitate the flow of solid particles in the shell. Due to the shape is also it is impossible for the individual solid particles to get caught with one another, which is what is called a Clumping of the solid particles is prevented.
- the solid particles expediently consist of polystyrene in order to be economical To ensure manufacture and easy handling of the grinding shoe.
- the shell is preferably, at least partially air-impermeable, in order to achieve an optimal one Ensure vacuuming of the envelope. Depending on the application, however, a little can air-permeable shell find application.
- Plastic can be used as the material for the cover, for example or rubber can be used.
- the casing is advantageously prestressed in order to temporarily fix the contour of the casing.
- the case can be pretensioned for example, by rolling up the cover on the holding part.
- connection to the pressure or vacuum source expediently also points a filter impermeable to the solid particles in order to suction the solid particles to prevent from the envelope. If the holding part has a fan, it will find it preferably used as a pressure or vacuum source.
- the shell is preferably at least partially coated with an abrasive in order to be economical Ensure manufacturing. Furthermore, such an arrangement of the Abrasives have the advantage of greater flexibility to adapt to the surface of a object to be processed, since the coating is designed to be flexible can be.
- the sleeve has a connecting means for an abrasive bearing layer to replace the used abrasive to allow without changing the whole sanding pad.
- a connecting means for an abrasive bearing layer to replace the used abrasive to allow without changing the whole sanding pad.
- a Velcro fastener can be used.
- the shell is expediently deformable in the area of the abrasive, so that the rest Part of the shell can be used to stabilize the abrasive.
- the cover is advantageously detachable from the holding means in order to use covers with to allow different properties.
- 1 and 2 is a grinding shoe according to the invention with a holding part 1, a flexible Shell 5 and an abrasive 3, partially shown in cross section.
- the holding part 1 has an intake port 8, which with a pressure or not shown Vacuum source is connectable.
- the holding part 1 is for better guidance of the grinding shoe provided with a handle 9, which has an operating element 10 with which, for example an, the grinding shoe vibrating, electric motor can be controlled.
- the sleeve 5 is on the side facing away from the abrasive 3 with the holding part 1 by spring elements 11 releasably connected.
- An opening arranged between the holding part 1 and the casing 5 4 has an impermeable to the solid particles 12 contained in the shell 5, sieve-like filter 7 to prevent suction of the same from the casing 5.
- the Abrasive 3 is releasably connected to the sheath 5 by means of a Velcro fastener 15.
- the flexible shell 5 adapts under the pressure of the solid particles 12 of the surface 14.
- the solid particles solidify by vacuuming the casing 5 12 in the casing 5 and thus give it a firm contour as shown in FIG. 2. Switching off the vacuum source, not shown, equalizes the pressure difference between environment and shell 5 again and the shell 5 is flexible again.
