Description

Technical Field

[0001] The utility model relates to the technical field of claw poles, in particular to a claw pole positioning fixture. Background Art

[0002] Claw pole generators have the characteristics of simple manufacturing and low cost, and are mainly used in small power generation occasions. After the claw poles of the generator are precision-shaped, drilling is required. During the drilling process, a claw pole positioning fixture is needed. Existing claw pole positioning fixtures often have multiple sub-fixtures, and the multiple sub-fixtures clamp the claw poles from different directions of the claw poles. During the clamping and fixing process, the operator needs to manually adjust the sub-fixtures one by one. Since the forces applied by the sub-fixtures to different directions of the claw poles are carried out successively, it will cause uneven force on the claw poles after clamping, and the claw poles are prone to tilt or shift, and finally the concentricity between the drilled holes and the claw poles will be poor. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a claw pole positioning fixture to solve the above problems existing in the prior art.

[0004] The technical problem to be solved by the utility model is to provide a claw pole positioning fixture.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A claw pole positioning fixture includes a base, and a clamping mechanism for positioning the claw pole is arranged inside the base;

[0007] The clamping mechanism includes an electric push rod vertically arranged at the top of the inner cavity of the base. An installation block is arranged downward at the output end of the electric push rod. A plurality of hinged rods are hinged on the installation block. One end of the hinged rod away from the installation block is hinged with a moving block. A connecting rod penetrating through a sliding hole at the top of the base is arranged at the top of the moving block. A limiting block adapted to the claw pole is arranged at the top of the connecting rod.

[0008] The beneficial effect of the utility model is that after the claw pole is placed on the top of the base, the electric push rod is started. The electric push rod drives the installation block to move downward, drives the hinged rod to rotate inward through the installation block, and the hinged rod drives the moving block to move inward. When the moving block moves, it will drive the limiting block to move inward together through the connecting rod to clamp and fix the claw pole; the limiting blocks, connecting rods, moving blocks, hinged rods and installation blocks in all directions of the claw pole have the same structure, and the forces applied by the limiting blocks in different directions of the claw pole are carried out simultaneously and have the same magnitude.
