During the processing, the positioning block 4 is stabilized by the auxiliary positioning component 5, so as to avoid the phenomenon of position deviation, and ensure that the three-stage disc shaft has the processing accuracy that meets the use requirements.

[0031] Specifically, the mold support assembly 2 includes a plurality of grooves 2-1 arranged on the base 1, and a connecting column 2-2 is slidably installed on the inner side of the groove 2-1. The connection column 2-2 cooperates with the groove 2-1 to ensure the stability of the mold support 2-3 moving up and down. A mold support 2-3 is commonly provided on the top of the plurality of connecting columns 2-2. The mold support 2-3 is used to place the three-stage disc shaft to be processed. A spring 2-4 is provided between the groove bottom of the groove 2-1 and the connecting column 2-2. A damper 2-5 is provided on the inner side of the spring 2-4 and between the groove bottom of the groove 2-1 and the connecting column 2-2. The damper 2-5 is provided to provide resistance to the elastic force of the spring 2-4, thereby avoiding repeated vibration of the mold support 2-3 during the process of releasing the elastic force of the spring 2-4. When in use, the three disc shafts to be processed are placed on the mold support 2-3, and the three-stage disc shaft is formed in the process of pressing down the three-stage disc shaft workpiece.

[0032] Specifically, the driving component 9 includes a driving motor 9-1 arranged on the base 1, and a worm 9-2 is provided at the driving end of the driving motor 9-1, and an annular worm gear ring 9-3 meshingly connected with the worm 9-2 is provided on the side wall of the annular rotating seat 7.

[0034] Specifically, a slide rail 10 is provided on the inner wall of the upper strip opening 3, and a slide groove 11 adapted to the slide rail 10 is provided on the side wall of the positioning block 4.

[0035] Specifically, the auxiliary positioning component 5 includes an extrusion plate 5-1 arranged on the inner wall below the slide groove 11, and the contact end of the extrusion plate 5-1 is provided with an anti-skid pad 5-2. The end of the extrusion plate 5-1 away from the slide rail 10 is provided with a resistance rod 5-3 arranged through the slide groove 11, and at least two resistance rods 5-3 are provided. During the descending process of the mold support component 2, the bottom of the resistance rod 5-3 contacts the base 1, so that the extrusion plate 5-1 and the anti-skid pad 5-2 move upward inside the slide groove 11 and contact the slide rail, thereby increasing the friction between the positioning block 4 and the mold support component 2. During the processing, the positioning block 4 is stabilized by the auxiliary positioning component 5, which avoids the phenomenon of position deviation and ensures that the three-stage disk shaft has a processing accuracy that meets the use requirements.

[0037] Specifically, the abutting end of the positioning block 4 is set as a V-shaped opening. By setting the V-shaped opening, it is possible to fix the three-stage disk shafts of different sizes. By increasing the contact points between the positioning block 4 and the three-stage disk shaft, the stability of the positioning of the three-stage disk shaft by the positioning block 4 is ensured.

[0038] Specifically, the bottom surface of the arc-shaped groove 8 is set as an inner arc surface, and the bottom of the slide rod 6-4 is set as an arc surface that matches the bottom surface of the arc-shaped groove 8. By setting the bottom of the slide rod 6-4 as an arc surface, the friction between the slide rod 6-4 and the arc-shaped groove 8 is effectively reduced, thereby improving the service life of the equipment.

[0039] Working principle: During the use of the utility model, first, the three-stage disc shaft processing part is placed on the mold support assembly 2, and the driving assembly 9 is started to drive the annular rotating seat 7 and the arc groove 8 on the annular rotating seat 7 to rotate, and the arc groove 8 drives several connecting assemblies 6 and the positioning block 4 to approach each other to automatically position the three-stage disc shaft. During the descent of the mold support assembly 2, the auxiliary positioning assembly 5 stabilizes the positioning block 4, so that the mold support automatically positions the three-stage disc shaft, ensuring that the three-stage disc shaft has a processing accuracy that meets the use requirements.
