Description
Technical field
The present invention relates to cutting technique field, specially a kind of changeable clamping face and the cutting that can restore automatically folder
Tool.
Background technique
In material processing, it is often necessary to be cut to material, cut the material into the shape of needs, cut
Before, it needs first to be fixed material with fixture, just can guarantee the stabilization of positions of materials in cutting process.
Current fixture clamping face shape is fixed, and mainly has a shapes such as plane or curved surface, can be with when clamping regular shape
Material is tightly clamped, but is easy to appear the case where material skids when clamping irregular shape, leads to material processing fault,
Cause the waste of material.
Therefore, we have proposed a kind of changeable clamping face and the cutting that can restore automatically solves above ask with fixture
Topic is firmly clamped material by changing clamping face shape, and tube material is not the shape or irregular shape of rule,
Clamping, and can restore to the original state when not clamping material, the waste of material is avoided, production cost is reduced.
Summary of the invention
The present invention is to realize that technical purpose adopts the following technical scheme that a kind of changeable clamping face and what can be restored automatically cut
It cuts and uses fixture, including pedestal, be rotatably connected to the screw rod for running through and extending to base right side, the right side of screw rod in the middle part of the pedestal
Side is fixedly connected with handwheel, and the both ends of screw rod are threaded with spiral shell block, supporting rod, supporting rod are fixedly connected at the top of spiral shell block
