[0006] Preferably, a fixed core rod base is fixedly connected to the middle portion of the lower end surface of the movable base 2, and a positioning core rod is fixed to the lower end surface of the fixed core rod base, and the positioning core rod has a built-in strong magnet.

[0007] Preferably, a fixing fixture base is fixed to the middle portion of the upper end surface of the equipment fixing base.

[0008] Preferably, a fixed workpiece fixture bottom plate is fixed to the upper end surface of the movable base 1, and an auxiliary material 1 is fixed to the upper end surface of the fixed fixture base.

[0009] Preferably, the upper end surface of the bottom plate of the fixed workpiece fixture is provided with positioning pins around the auxiliary material 1, and the workpiece body is placed on the bottom plate of the fixed workpiece fixture.

[0010] Preferably, auxiliary material 2 is placed on the positioning mandrel.

[0011] In summary, compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The workpiece is placed on the fixture plate and fixed with positioning pins, which greatly reduces the friction between the workpiece and the working surface, improves the accuracy of pressing in auxiliary materials, and improves the quality of the product.

[0013] 2. Due to the tooling design of pressing multiple auxiliary materials at one time, the workpiece auxiliary material design has the function of strong magnetic suction, which also improves work efficiency and time efficiency.

[0014] 3. The workpiece is placed on a fixture plate with positioning pins, and the workpiece will not slide during press-fitting, which improves safety performance.

[0015] 4. The press-fitting tool has strong magnetic suction, which improves the efficiency of assembling auxiliary materials and reduces costs.

[0016] 5. The equipment has a simple structure and the fixtures are concise and clear, which is convenient for daily maintenance and easy repair. BRIEF DESCRIPTION OF THE DRAWINGS
