Abstract

The invention relates to an electric vacuum pump driving sleeve assembling device, and belongs to the field of automobile electric vacuum pump manufacturing. The electric vacuum pump driving sleeve assembling device is characterized in that a fixing frame of an electric press-fitting mechanism is fixedly connected with the upper portion of a workbench, a workpiece clamping mechanism is located below the electric press-fitting mechanism and fixedly connected with the upper portion of the workbench, a supporting frame of a gap locking mechanism is fixedly connected with the lower portion of theworkbench, the upper end of a driven lead screw of the gap locking mechanism is connected with the workbench in a threaded and penetrating mode, and the top end of the driven lead screw penetrates through a receding hole of a fixing plate of the workpiece clamping mechanism to make contact with the bottom face of a top shaft block. The device has the advantages of being novel in structure, stable,reliable and capable of accurately and effectively monitoring an assembled product, motor damage caused by overlarge single-direction stress of a motor shaft in the press fitting process of a drivingsleeve can be prevented, it is ensured that a gear motor is free of damage of supporting force, and enough supporting force can be provided for the motor shaft.

Description

technical field [0001] The invention relates to the field of manufacturing electric vacuum pumps for automobiles, and relates to an electric vacuum pump driving set assembly device. Background technique [0002] In the field of electric vacuum pump manufacturing for automobiles, the assembly of the drive sleeve is a key process, which will directly affect the quality, noise and life of the electric vacuum pump. The connection between the drive sleeve and the motor shaft is an interference fit, and the pressing force is relatively large. If the bottom of the motor shaft is not supported, the motor is easily damaged. If a large force is applied to the bottom of the motor shaft and used as a supporting force, it will still cause damage to the motor. Contents of the invention [0003] The invention provides an assembly device for the driving sleeve of an electric vacuum pump to solve the problem that the driving sleeve and the motor shaft are assembled with a relatively large...
