Abstract

The invention relates to the technical field of motor production and processing, and discloses a keyway processing fixture for a motor iron core, which solves the problems that manual operations are required to clamp the iron core body many times, the actual operation is relatively inconvenient, and the work efficiency is affected. The box body, the top of the control box body is provided with a fixed clamping plate and a movable clamping plate, the top inner wall of the control box body is provided with a positioning hole, and the top inner wall of the control box body is provided with a first rectangular hole. There is a movable adjustment plate, the top of the movable adjustment plate extends into the first rectangular hole, the control box body is provided with a first threaded rotation column, the first threaded rotation column penetrates the movable adjustment plate, the first threaded rotation column and the movable adjustment plate The connection method is screw connection; the lifting adjustment plate and the movable clamping plate can be driven to move at the same time, thereby completing the fixing of different positions of the iron core body, improving the stability of the clamping and improving the clamping efficiency.

Description

technical field [0001] The invention belongs to the technical field of motor production and processing, in particular to a keyway processing jig for motor iron cores. Background technique [0002] During the production and processing of the motor, it is usually necessary to open a keyway for the motor core so that it can be connected with the casing. During the processing of the keyway, the iron core of the motor must be fastened and fixed to prevent the position of the keyway from deviating or the width of the keyway from not meeting the design expectation, which will affect its assembly accuracy. However, in the prior art, clamps are used to clamp and fix both sides of the fixed iron core when machining the keyway, and the iron core may deviate in the radial direction during the machining process, thereby affecting the machining accuracy. At the same time, the existing tooling needs to surround the whole, resulting in larger volume and heavier weight of the tooling, high ...
