Precise spindle mounting auxiliary mechanism of multi-wire cutting equipment

Abstract

The invention provides a precision spindle mounting auxiliary mechanism for multi-wire cutting equipment, and relates to the field of bearing machining. The precise main shaft installation auxiliary mechanism of the multi-wire cutting equipment comprises a base plate, and four guide columns are fixedly connected to the top end of the base plate. The stress application rod is rotated to drive the rotating disc to rotate at the top end of the fixed disc, and the collision block fixedly connected to the lower end of the rotating disc is slidably connected to the interior of the annular groove in the corresponding position in the rotating process of the rotating disc, so that the stress application rod is rotated to drive the rotating disc to collide with the fixed disc, and the fixed disc drives the lead screw to rotate under the collision force; the rotation of the lead screw can drive the pressure seat to stably move downwards, so that the impact kinetic energy can be converted into the axial movement kinetic energy of the lead screw, the trace force application and trace movement are realized, and then the assembly of different bearings can be completed by replacing the movable pressing sleeve in the movement process of the pressure seat. Therefore, high-precision installation of a plurality of groups of bearings can be realized accurately and stably under the condition that the precision of the bearings and the shaft seat machining surfaces is not damaged.

Description

Technical field [0001] The present invention relates to the field of bearing processing technology, specifically a multi-wire cutting equipment precision spindle mounting auxiliary mechanism. Background [0002] Multi-wire cutting is a kind of high-speed reciprocating movement of the wire, the abrasive is brought into the semiconductor processing area for grinding, the semiconductor and other hard and brittle materials are cut into hundreds of sheets at the same time a new cutting processing method, CNC multi-wire cutting machine has gradually replaced the traditional internal circular cutting, becoming the main way of silicon wafer cutting processing. [0003] The spindle part is the core part of the multi-wire cutting equipment, due to the requirements of cutting force and rotational stability, the spindle generally adopts multi-diagonal contact precision bearing series installation, due to the series installation of multiple groups of bearings of the same model, so that the s...
