Abstract

The invention provides a workpiece clamping mechanism of a multi-wire cutting machine. The surface of a clamped silicon crystal bar is stressed uniformly, and the processing quality is good. The workpiece clamping mechanism comprises the silicon crystal bar. The workpiece clamping mechanism is characterized in that: the upper surface of the silicon crystal bar is tightly attached to a glass plate, the upper surface of the glass plate is fastened and connected with a lower lifting plate, the upper part of the lower lifting plate is inserted into a linear installation groove of an upper lifting plate, the position of the upper lifting plate is fixed, the section of the linear installation groove is trapezoidal, the bottom of the linear installation groove is open, the central position of the upper end face of the lower lifting plate is provided with a small end up straight groove body, double-lug ring seats are uniformly distributed above the upper lifting plate, the positions of the uniformly distributed double-lug ring seats are fixed, the lower part of each double-lug ring seat is connected with a cylinder, the cylinders are connected with the same pneumatic valve, ejector rods of the cylinders are connected with a lower bracket, two sides of the lower bracket press the top of a pull rod, and the bottom of the pull rod is arranged in the small end up straight groove body.

Description

technical field [0001] The invention relates to the technical field of the structure of a multi-wire cutting machine, in particular to a workpiece clamping mechanism of the multi-wire cutting machine. Background technique [0002] The clamping mechanism of the existing equipment is rigid clamping. Due to the uneven surface of the silicon ingot, stress concentration will occur after clamping, which affects the processing quality. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a workpiece clamping mechanism of a multi-wire cutting machine, which has uniform force on the surface of the silicon ingot after clamping and good processing quality. [0004] The technical solution of the workpiece clamping mechanism of the multi-wire cutting machine is as follows: it includes a silicon crystal rod, characterized in that: the upper surface of the silicon crystal rod is in close contact with a glass plate, and the upper surface o...
