Fixing device for cylindrical silicon rod clamp

Abstract

The invention provides a fixing device for a cylindrical silicon rod clamp, aiming at solving the problems that indentations are easily formed on the surface of a silicon rod when a clamping claw of an existing cylindrical silicon rod clamp is used for clamping the silicon rod. The fixing device comprises four lower pressing blocks which are vertical to guiding columns of the upper surface are arranged at the four corners of the upper surface respectively; a thread is arranged at the upper part of each guiding column; the fixing device further comprises a lower module, an upper module, an upper pressing block and four pressing nuts; the lower module, the upper module and the upper pressing block sleeve the four guiding columns in sequence from top to bottom; the four pressing nuts are arranged on the four guiding columns respectively; upper arc-shaped grooves matched with the silicon rod are formed in the lower surface of the upper module; a lower arc-shaped groove matched with the silicon rod is formed in the upper surface of the lower module. According to the fixing device, the upper pressing block, the lower pressing blocks, the upper module and the lower module are arranged and are convenient to detach; cylinders with different diameters can be fixed through replacing the upper module and the lower module which have the different sizes and the commonality is strong; the indentations are not formed when the upper arc-shaped grooves of the upper module and the lower arc-shaped groove of the lower module are used for clamping the silicon rod.

Description

technical field [0001] The invention relates to an accessory for a cylindrical silicon rod clamp, in particular to a fixing device for a cylindrical silicon rod clamp. Background technique [0002] When cutting a cylindrical silicon rod into a silicon wafer, it is necessary to use a clamp to fix the silicon rod; when the existing cylindrical silicon rod clamp uses claws to clamp the silicon rod, it is easy to produce indentations on the surface of the silicon rod. Affect the quality of the product; when the upper and lower curved plates are used to clamp the silicon rod, the surface of the clamp or the silicon rod is not smooth and other defects will cause the clamping of the silicon rod to be unstable. When cutting the silicon rod, the product will be affected by shaking quality; in addition, the curved plate can only hold silicon rods of one diameter, and its performance is single.
