Design proposal for grinding copper holder locking notch and clamping device

Abstract

The invention provides a design proposal used for grinding and processing the locking notch of a copper retaining frame, and a clamping device; wherein, the clamping device consists of a base 5, a left column 6, a pulling pin 7, a connecting plate 8, a pulling handle 9, a positioning core shaft 10, a left positioning pin 11, a retaining ring 12, a pressure spring 13, a guide sleeve 14, a right positioning pin 15, a pulling fork frame 16, a pin shaft 17, a pulling fork 18, a position limit block 19, a right column 20, a positioning column 21 and a screw 22; the positioning pin which can move to the left side and the right side is used for clamping the retaining frame 3 to be processed; the axial clamping force of the positioning pin comes from the pressure spring; the axis center lines of the two positioning pins are concentric; the retaining frame to be processed is arranged on a positioning core shaft, the positioning core shaft can be adjusted upwards and downwards; the pulling of left positioning pin and the right positioning pin must be a linked process and is carried out by the pulling pin, the connecting plate, the pulling handle, the pulling fork frame, the pin shaft, the pulling fork and the position limit block. The clamping device has compact structure and balanced clamping force, and can lead the left positioning pin and the right positioning pin to be pulled out orclamped inwards simultaneously, thus achieving the compressing or loosening the retaining frame to be processed.

Description

technical field [0001] The invention belongs to the technical field of bearing cage processing, in particular to a design method and a clamping device for grinding and cutting a lock port of a copper cage. Background technique [0002] figure 1 It is a copper solid cage with a small size and a narrow width. When grinding and cutting its lock, it is usually used figure 2 The schematic diagram of the conventional clamping device for grinding and cutting locks is shown. Place the cage 3 to be processed on a fixed mandrel 4, turn the cage slightly so that the pocket positioning pin 1 with elastic pressure is inserted into a pocket of the cage for indexing and unilateral compression, and at the same time The finger pressure F acts on the opposite side of the cage, so that the cage as a whole is in a compressed state, and the grinding wheel 2 is moved back and forth to complete the grinding and cutting of one of the locks. Repeat the above process to complete the grinding an...

AI Technical Summary

Problems solved by technology

[0003] The indexing and positioning of the above-mentioned special fixtures are convenient and quick, but due to the small size of the cage to be processed and the large grinding wheel, the pressing finger is too close to the grinding wheel. If you don't pay attention, your fingers will be worn by the grinding wheel and cause unnecessary accidents
