It is traditional when being drilled on drilling machine, it is, first by workpiece on fixture, then drill bit is directed at first drill bushing to carry out Another drill bushing is directed at drill bit by drilling, then manual movable clamp, bores second hole, the like, the fixture of such a structure is present The problem of be:Using positioned between labor intensity that is cumbersome, adding workman, drill bit and drill bushing it is inaccurate, need to correct repeatedly Position, greatly reduces operating efficiency.
Utility model content
The purpose of this utility model is a kind of simple to operate, safety of offer, positions the reliable and high vertical hole drill of precision Bed fixture, can greatly improve the operating efficiency of vertical hole drill machine.
For achieving the above object, the technical scheme that the utility model is taken is:A kind of folder for vertical hole drill machine Tool, including clamp body, the centre of the clamp body are provided with shoulder hole, and the shoulder hole is built with back-moving spring, the shoulder hole Both sides be separately installed with handle and elastic clip headstock, the elastic clip headstock collet be installed, the clamp body It is fixedly arranged above on bushing plate, the bushing plate and is provided with drill bushing hole, renewable bushing is arranged in the drill bushing hole by bushing, institute The side for stating clamp body is respectively fixed with connecting plate and support bar, the connecting plate and is fixed with the second bearing pin from top to bottom, institute State support bar to be connected with chamfered edge nut thread through its end after the round end groove on briquetting, the round end channel profiles on the briquetting are big In the outline of the chamfered edge nut, the briquetting is connected with the second bearing pin revolute pair, and V-type is also equipped with the briquetting Block.
In such scheme, positioned between the clamp body and the bushing plate by alignment pin, the clamp body and It is fixed between the bushing plate by screw.
In such scheme, it is fixed between the V-block and the briquetting by the first bearing pin.
In such scheme, the bushing is interference fitted with the drill bushing hole, and the bushing is matched somebody with somebody with the renewable bushing gap Close.
In such scheme, rectangular channel is provided with the bottom surface of the clamp body.
The beneficial effects of the utility model:Clamp structure of the present utility model for vertical hole drill machine is simple, handling side Just, clamping device is simple to operate, safe, and positioning is reliable and precision is high, and the financial cost that it is manufactured is low.
