Description
Technical field
The utility model is related to field polysilicon, more particularly to a kind of polysilicon cutting fixture.
Background technology
Crystal silicon chip is widely used in microelectronics or area of solar cell at present, is silicon material through vertical pulling method or casts legal system of splitting
It at monocrystal rod or polycrystal silicon ingot, after cutting into silico briquette, needs to be ground the surface of silico briquette, improves surface roughness.Due to
In process of lapping, suffered external force is larger, needs to be clamped silico briquette, is generally clamped in the prior art using bilateral, but this
Kind clamping mode is fine in unidirectional grinding, when grinding wheel, which intersects, to be ground or when needing to commutate, generally requires adjustment clamping side
To ensure that the Impact direction of silico briquette is identical with the direction of clamping force, otherwise be easy to cause the cheap of silico briquette in addition pop-up.And this
Kind mode of operation is relatively complicated.Also there is the design using Bidirectional clamping in the prior art, but this design often will be unidirectional
It clamps and carries out cross arrangement, both direction, which needs to carry out clamp operation twice, could complete to clamp, then on the contrary, needing two when dismounting
Secondary release clamping device, cumbersome, working efficiency is relatively low.
Utility model content
The utility model provides a kind of polysilicon cutting fixture, can solve the problems, such as pointed in background technology.
A kind of polysilicon cutting fixture, including positioning table, the first transmission shaft, second driving shaft, handle and four clampings
Plate offers the first sliding groove and second sliding slot on the positioning table, and the first sliding groove and the second sliding slot square crossing are set
It sets, first both ends of the drive shaft is rotatably arranged in the first sliding groove, and any one end of first transmission shaft is prolonged
The handle is extended to outside the positioning table and is connected to, the second driving shaft both ends are rotatably arranged in described second and slide
In slot, first transmission shaft and the second driving shaft spatial vertical are arranged in a crossed manner, have snail in the middle part of first transmission shaft
The both sides of rod segment, the worm screw section offer oppositely oriented screw thread, and the worm screw section is corresponded in the middle part of the second driving shaft
Position have with the matched worm gear of worm screw section, the both sides of the worm gear offer oppositely oriented screw thread, the clamping
Board bottom portion have with the first sliding groove and the matched sliding block of the second sliding slot, offer and the screw thread on the sliding block
Matched threaded hole, two pieces of grip blocks are separately positioned on the both sides of the worm screw section, another two pieces of grip block difference
It is arranged in the both sides of the worm gear.More preferably, the sliding slot cross section is T-type.
The utility model provides a kind of polysilicon cutting fixture, drives the first transmission shaft to rotate using handle, and first passes
Oppositely oriented screw thread drives two grip blocks close to each other or is located remotely from each other on moving axis, while the worm screw meeting on the first transmission shaft
It drives worm gear to rotate and then drives second driving shaft rotation, the oppositely oriented screw thread on second driving shaft drives another two clamping
Plate is synchronized close or is located remotely from each other, and realizes that unilateral adjustment bi-directional synchronization is clamped or dismantled, simple to operate.
