[0024] Please see Figures 1-5In this embodiment of the present invention, an automatic stacking fixture for a disc motor stator core includes a worktable 1. A core placement groove 2 is provided on the upper surface of the worktable 1. A fixed column 4 is connected to the upper surface of the worktable 1. A top plate 5 is connected to the upper surface of the fixed column 4. A hydraulic cylinder 6 is installed inside the top plate 5. A hydraulic telescopic rod 7 is installed at the output end of the hydraulic cylinder 6. A lifting plate 8 is connected to the output end of the hydraulic telescopic rod 7. A limit mechanism 3 is provided inside the fixed column 4. A pressure sensor 9 is installed on the upper surface of the lifting plate 8. An elastic buffer pad 10 is located on the bottom surface of the lifting plate 8. A stacking plate 11 is connected to the bottom surface of the elastic buffer pad 10. A PLC controller 12 is installed on the upper surface of the worktable 1. The worktable 1 has two positioning holes 13 inside. The bottom surface of the lifting plate 8 is connected to two positioning rods 14. The upper surface of the worktable 1 is connected to two fixing plates 15. Electric push rods 16 are installed on the side of the two fixing plates 15 that are close to each other. The output end of the two electric push rods 16 is connected to an arc block 17. The limiting mechanism 3 includes a limiting groove 301. A limiting block 302 is slidably connected inside the limiting groove 301. The front of the limiting block 302 is connected to the back of the lifting plate 8. The elastic buffer pad 10 can effectively buffer the impact force of the stacking plate 11 on the stator core during the pressing process, prevent the core from being damaged due to excessive force, protect the core in all directions, and improve the product qualification rate.

[0025] The two arc-shaped blocks 17 are connected to protective pads 18 on their adjacent sides. Both protective pads 18 are made of rubber. The front of the fixed column 4 is connected to the first reinforcing seat 19. The upper surface of the first reinforcing seat 19 is connected to the bottom surface of the top plate 5. The bottom surface of the workbench 1 is connected to two sets of support legs 20. The bottom end of each support leg 20 is connected to a mounting plate 21. Each mounting plate 21 has a set of mounting holes 22. The rubber protective pads 18 on the sides of the arc-shaped blocks 17 prevent scratching and damage to the surface of the iron core when positioning it. The first reinforcing seat 19 can be used to reinforce the top plate 5, making the connection between the top plate 5 and the fixed column 4 more secure. The mounting plate 21 and the mounting holes 22 make it easy for workers to fix the device to the ground.

[0026] A toolbox 23 is placed under the workbench 1. A handle 24 is connected to the front of the toolbox 23. Two second reinforcing seats 25 are connected to the upper surface of the workbench 1. The sides of the two second reinforcing seats 25 that are close to each other are connected to the sides of the two fixed plates 15 that are far apart from each other. A human-machine interface touch screen 26 is installed on the front of the PLC controller 12. An operation indicator light 27 is installed on the upper surface of the PLC controller 12. The toolbox 23 allows the staff to conveniently store various maintenance tools. The second reinforcing seats 25 can reinforce the fixed plates 15, making the connection between the fixed plates 15 and the workbench 1 more secure. The human-machine interface touch screen 26 and the operation indicator light 27 allow the operator to intuitively understand the operating status of the tooling, which is convenient for troubleshooting and daily maintenance.

[0027] The working principle of this utility model is as follows: When using this device, the stator core of the disc motor is first placed in the core placement slot 2 of the workbench 1. The electric push rod 16 pushes the arc block 17, and the protective pad 18 on the side of the arc block 17 positions and clamps the core, ensuring that the core is fixed in position during the stacking process. The operator sets the stacking parameters, such as pressure value and stacking stroke, through the human-machine interface touch screen 26 of the PLC controller 12. After setting, the PLC controller 12 controls the hydraulic cylinder 6 to work. The output end of the hydraulic cylinder 6 drives the hydraulic telescopic rod 7 to extend downward. The hydraulic telescopic rod 7 pushes the lifting plate 8 to move downward along the limiting mechanism 3 in the fixed column 4. The stacking plate 11 on the bottom surface of the lifting plate 8 gradually approaches the stator core. During the stacking process, the pressure sensor 9 on the lifting plate 8 monitors the stacking pressure in real time and feeds the pressure data back to the PLC controller 12. When the pressure reaches the set value, the PLC controller 12 controls the hydraulic cylinder 6 to stop working, completing one stacking action. The above is the complete operation process of this device.
