Abstract

The utility model provides a four-claw self-centering clamp for clamping a single-crystal-silicon workpiece. The clamp can reasonably and effectively clamp the single-crystal-silicon workpiece, and is characterized in that the clamp comprises a plane thread block, wherein, the plane thread block is embedded in a lug boss of the clamp body; the clamp body is embedded in the plane thread block; the clamp body, the plane thread block and the lug boss of the clamp body are connected with each other through locking gears; four self-centering clamping claws are mounted on the connected clamp body and the end surface of the thread block; and the connected clamp body, the end surface of the thread block and the clamping claws are in threaded connection.

Description

A kind of four paws self-centering fixture of clamping monocrystalline silicon workpiece

(1) technical field

The utility model relates to the clamping field of monocrystalline silicon workpiece, is specially a kind of four paws self-centering fixture of clamping monocrystalline silicon workpiece.

(2) background technology

Clamping of existing monocrystalline silicon workpiece is the rectangle of fillet because its monocrystalline silicon workpiece is individual four jiaos, wastes time and energy so clamp relatively, and can not effectively support.

(3) summary of the invention

At the problems referred to above, the utility model provides a kind of four paws self-centering fixture of clamping monocrystalline silicon workpiece, and it can be rationally, effective clamping monocrystalline silicon workpiece.

Its technical scheme is such, it is characterized in that: it comprises the flat thread piece, described flat thread piece is set in the clamp body boss, clamp body is set in described flat thread piece, be connected with locking gear respectively between described clamp body, flat thread piece and the clamp body boss, the clamp body that links to each other and the end face of described threaded block are equipped with four self-centering jaws, between described continuous clamp body and described threaded block end face and the described jaw three with being threaded.

It is further characterized in that: the clamping face of described self-centering jaw is the plane; The clamping face of described self-centering jaw is coated with protective layer; Described clamp body rear portion is connected with end cap with bolted; Described locking gear excircle has a driving hole.

In the said structure of the present utility model; rotating in the driving hole on the spanner insertion locking gear; locking gear rotates and drives the rotation of flat thread piece; the flat thread that the flat thread piece rotate to drive the back side just make drive four self-centering jaws simultaneously to the center near or withdraw from; play the effect of clamping, the clamping face of described self-centering jaw is the plane, and its surface is coated with protective layer; so that metal material and monocrystalline silicon are isolated, play the effect of protection monocrystalline silicon.So this utility model can reasonable, effective clamping monocrystalline silicon workpiece.
