Description

A jig for punching holes in the middle cover of a motor

technical field

The utility model relates to motor component processing equipment, in particular to a punching jig for an intermediate cover of a motor.

Background technique

The middle cover of the motor needs to be punched at a specific position. Before punching, the middle cover must be positioned well and the tool must be checked to ensure that the opening position is accurate. The traditional processing fixture clamps the semi-finished middle cover from the outside and clamps it. processing, but because the middle cover is an aluminum casting blank, there is a certain error in the shape, which will cause inaccurate positioning of the fixture, resulting in inaccurate punching positions on the middle cover, requiring multiple tool calibrations, which reduces production efficiency.

Utility model content

The purpose of the utility model is to provide a jig for punching a middle cover of a motor with precise positioning and high processing efficiency.

In order to achieve the above object, the utility model provides the following technical solutions:

A punching fixture for the middle cover of a motor, comprising a bottom plate, and several positioning mechanisms are arranged on the bottom plate. core, and fixed on the bottom plate by the central cover, the positioning pin used to position the angle of the middle cover is fixed on the bottom plate, and the spring fastening box used to press the middle cover on the positioning pin is fixed on the positioning pin On the bottom plate above the pin, the spring fastening box includes a baffle plate, a spring and a push rod, the spring is connected to the baffle plate fixed on the spring fastening box, and the other end of the spring is connected to the push rod.

As a further solution of the utility model: the base plate is provided with positioning holes for fixing and positioning the base plate on the processing machine tool.

As a further solution of the utility model: a total of 6 positioning mechanisms are arranged on the bottom plate.

The beneficial effects of the utility model are: the punching jig for the middle cover of the motor confirms the center of the middle cover through the positioning core, and then positions the angle of the middle cover through the positioning pins to realize precise positioning, and the side support force provided by the spring fastening box will The middle cover is pressed against the positioning pin. Even if the shape is a bit wrong, the spring fastening box can ensure that the middle cover is close to the positioning pin and can be positioned accurately. The punching jig for the middle cover of the motor is equipped with 6 positioning mechanisms, and the knife can be set at one time. , determine the punching positions of the 6 intermediate covers to be processed, and the processing efficiency is high.
