Clamp for machining motor end cover

Abstract

The invention relates to a clamp for machining a motor end cover. The clamp comprises an end plate, a spindle, a jacket and a pull rod, wherein the end plate is axially hollow; the spindle is axially hollow; the inner end of the spindle is arranged on the end plate; the spindle and the end plate are guaranteed to be on the same axis; the spindle is radially provided with a through groove; a pin is arranged in the through groove; the width of the through groove in the axial direction of the spindle is greater than the diameter of the pin; the outer end head of the spindle is sleeved in the jacket; and two end heads of the pin, extending out of the through groove, are connected with the end head in the jacket. The clamp is rational in design; one clamp can be used for producing motor end covers of different types; the frequency and the time for replacing the clamp are saved; the production efficiency is increased; and the machining accuracy requirement of the end cover can also be guaranteed excellently. The time for mounting the end cover on the clamp and disassembling the end cover from the clamp is also greatly shortened, and the clamp is extremely convenient.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture used for processing the end cover of a motor. Background technique [0002] It is estimated that there are at least 300 to 500 types of motor end covers, and the coaxiality between the ends of the end covers and the bearing hole is required to be ≤0.05mm. However, the production batches of these end covers are not large. In order to produce such products, a lot of work needs to be done. Due to the variety of fixtures and the poor positioning accuracy of the fixtures, it takes a long time to adjust the fixtures (usually 5 to 8 hours) when producing such products. In addition, the fixtures are also unstable, and it is easy to produce defective products. low efficiency. Contents of the invention [0003] Therefore, an object of the present invention is to provide a jig for machining motor end covers with high versatility, which is applicable to various types of motor end covers.
