AI Technical Summary

Technical Problem

Existing motor housing drilling devices are prone to causing the housing to dent or deform during fixing, affecting the dimensional accuracy and surface quality. In addition, the friction between the drill bit and the workpiece generates heat, leading to tool wear and workpiece thermal deformation, which affects the machining accuracy.

Method used

The system employs flexible fixing components and a spray cooling system. The motor housing is fixed by the support plate opened by an electric push rod, and the nozzle is aimed at the drilling area to cool and reduce dust, thus preventing housing deformation and extending tool life.

Benefits of technology

Ensure the dimensional accuracy and surface quality of the motor housing, improve drilling accuracy and consistency, extend tool life, and improve the working environment and operational safety.

Abstract

The utility model discloses a punching device for motor shell production, and relates to the technical field of motor shell punching. Comprising a mounting base, a punching mechanism used for motor shell production is arranged on the mounting base, the motor shell needing to be punched is horizontally arranged on the outer walls of supporting plates in a sleeving mode and attached to the side wall of a limiting support, sliding blocks are pushed, the four sets of supporting plates are expanded, and therefore the inner wall of the motor shell is expanded and fixed; the motor shell punching device has the advantages that the motor shell is prevented from being sunken due to pressure during punching, the boundary dimension precision and the surface quality of the motor shell are guaranteed, and subsequent motor assembling and other procedures can be smoothly carried out; the clamping plate is pushed through the second electric push rod to be close to the outer wall of the lowest end of the motor shell; and a group of supporting plates at the lower end of the inner wall of the motor shell are matched to clamp the motor shell, so that the machining stability is ensured, the accuracy of the punching position is improved, and the punching precision and consistency are ensured.
