Assembly and disassembly device for electric spindle bearing

Abstract

The invention relates to an assembly and disassembly device for an electric spindle bearing. The assembly and disassembly device comprises a thread spindle bracket, a supporting press plate, a wrench, thrust self-aligning roller bearings, a radial length adjustment bracket, connection rods, claw hooks, adjusting pins and cylindrical pins. The thread spindle bracket is matched with the supporting press plate in a threaded mode, the wrench is installed at the top end of the thread spindle bracket, the thread spindle bracket is connected with the radial length adjustment bracket through the thrust self-aligning roller bearings, the connection rods are uniformly installed on the radial length adjustment bracket in the circumferential direction, the adjusting pins adjust the positions of the connection rods, and the claw hooks are connected with the connection rods through the cylindrical pins. The assembly and disassembly device is suitable for manual assembly, can assemble and disassemble bearings of different apertures without damaging the bearings basically, and is compact in structure, convenient to use and low in manufacturing cost.

Description

technical field [0001] The invention relates to a device for installing and dismounting an electric spindle bearing, belonging to the field of electromechanical engineering. Background technique [0002] At present, high-speed electric spindles have penetrated into various fields, especially in CNC machining, automobile, aerospace, medicine and other industries, and electric spindles have been widely valued and applied. It has the advantages of ultra-high speed, good rigidity, high rotation accuracy, small temperature rise during operation, good stability, low power consumption, long life and high reliability. To meet these requirements, the manufacture and dynamic balance of the electric spindle, the support (bearing) of the spindle, the lubrication and cooling of the spindle system, the rigidity of the spindle system, etc. Can not be ignored. [0003] The bearings of the electric spindle need to be replaced frequently due to long-term rotation under ultra-high-speed cond...
