Abstract
The to -be -solved technical problem of the utility model is to provide a clamping anchor clamps to avoid causing the injury at the clamping in -process to workpiece surface. In order to solve the technical problems, the utility model provides a clamping anchor clamps of lateral expansion which comprises add briquetting, " L " shape expand expansion block, lock screw and orientation module, the shape that adds the briquetting is mated with the shape of mounting hole, adds the briquetting and passes through the lock screw lock is in the mounting hole. Add the briquetting to the expansion block pressurization of expanding, thereby it being tight to make the outside inflation edgewise of expansion block of expanding press from both sides the work piece, and expanding expansion block before the inflation, the clearance between its and the work piece is great, can not constitute the surface of work piece and injure.
Description
Technical field
The utility model relates to a kind of frock, is a kind of clamping device specifically.
Background technology
For the workpiece that shape is special, clamping device generally can be used to clamp when producing.At present, the clamping device that the production of workpiece uses is board-type, owing to being all matched in clearance between the fixture block of clamping device and workpiece, so in clamping process, easily causes surface of the work to scratch.Therefore the existing production for workpiece use the structure of frock clamp on production and application, there is disadvantage and hidden danger.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of clamping device, to avoid damaging surface of the work in clamping process.
For solving the problems of the technologies described above, the utility model provides a kind of clamping device of lateral expansion, comprises pressurizing block, " ┴ " shape expanding block, lock screw and locating module; Be provided with the embedding groove of " ┴ " shape in locating module, expanding block is embedded in embedding groove, and is bolted in locating module; The top of expanding block is protruded from embedding groove, and offers an installing hole downwards, and the cross section of installing hole is inverted isosceles trapezoid; The shape of pressurizing block and the form fit of installing hole, its cross section is also inverted isosceles trapezoid, and the sectional dimension of installing hole is less than the sectional dimension of pressurizing block; Pressurizing block is locked in installing hole by described lock screw.
Further, the cross section of installing hole is inverted isosceles trapezoid.
Further, the top of expanding block is clamping end, and the clamping face of clamping end is broached-tooth design, so can reduce the contact area of clamping face and workpiece.
Compared with prior art, the utility model is pressurizeed to expanding block by pressurizing block, expanding block is outwards expanded thus from the side by Workpiece clamping, and expanding block before inflation, and the gap between itself and workpiece is comparatively large, can not form injury to the surface of workpiece.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the required accompanying drawing used in describing embodiment is briefly described.
Fig. 1 is the side sectional view of the clamping device of a kind of lateral expansion disclosed in the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
See Fig. 1, the clamping device of lateral expansion comprises pressurizing block 1, " ┴ " shape expanding block 2, lock screw and locating module 4; Be provided with the embedding groove of " ┴ " shape in locating module, expanding block is embedded in embedding groove, and is bolted in locating module; The top of expanding block is protruded from embedding groove, and offers an installing hole downwards, and the cross section of installing hole is inverted isosceles trapezoid; The shape of pressurizing block and the form fit of installing hole, its cross section is also inverted isosceles trapezoid, and the sectional dimension of installing hole is less than the sectional dimension of pressurizing block; Pressurizing block is locked in installing hole by described lock screw.
Workpiece is placed on fixture, and then pressurizing block is placed in installing hole, screw lock screw, by making pressurizing block, expanding block is pressurizeed, expanding block is made outwards to expand thus from the side by Workpiece clamping, and expanding block before inflation, the gap between itself and workpiece is comparatively large, thus can not form injury to the surface of workpiece.
The top of expanding block is clamping end, and the clamping face of clamping end is broached-tooth design 5, so can reduce the contact area of clamping face and workpiece.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
