[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-3 A rotor automatic crimping tool comprises a base plate 1, a rotating disk 2 is arranged above the base plate 1, a rotating drive mechanism 3 for driving the rotating disk 2 to rotate is arranged on the base plate 1, a plurality of evenly distributed bases 4 are arranged near the circumference of the rotating disk 2, a positioning groove 41 is opened on the base 4, and a rotor core 5 for rotor installation is arranged in the positioning groove 41 on the base 4, each base 4 is provided with a clamping and fixing mechanism 6, the clamping and fixing mechanism 6 can fix the rotor cores 5 of different sizes, and the rotating disk 2, the rotor core 5 installed thereon and the rotor can be driven to rotate by the rotating drive mechanism 3.

[0025] A gantry 7 is mounted on the base plate 1, extending to the top of the rotating disk 2. A hydraulic cylinder 8 is provided on the gantry 7 and corresponding to one of the bases 4. The cylinder body of the hydraulic cylinder 8 is fixedly mounted on the gantry 7, and the cylinder rod of the hydraulic cylinder 8 is fixedly connected to a pressure head 9. A controller 10 is provided on the gantry 7, which is a touch-screen controller. A through hole 14 is provided at the bottom of the rotating disk 2 corresponding to each base 4. When the rotor core 5 and the rotor rotate to below the pressure head 9, the hydraulic cylinder 8 is extended and retracted by the controller 10, which drives the pressure head 9 to move, thereby achieving automatic crimping of the rotor. In addition, the crimping height can be set by the controller 10 according to demand, and the rotating disk 2 is driven to rotate by the rotary drive mechanism 3, so that the crimping station operates in a cycle, thereby improving work efficiency.

[0026] According to the above structure, when using the crimping tool of this embodiment, the operator places the rotor core 5 in the positioning groove 41 of the base 4 and inserts the rotor into the rotor core 5. The clamping and fixing mechanism 6 on each base 4 can accommodate rotor cores 5 of different sizes, ensuring that they are firmly fixed to the base.

[0027] Then, the rotary drive mechanism 3 drives the rotary disc 2 to rotate, so that the base 4 equipped with the rotor core 5 and the rotor corresponds to the pressure head 9 in sequence;

[0028] When the rotor core 5 rotates to the crimping position below the hydraulic cylinder 8, the controller 10 receives a signal and drives the hydraulic cylinder 8 to extend or retract. The ram 9, connected to the rod of the hydraulic cylinder 8, moves accordingly, crimping the rotor. The crimping height is set by the operator on the controller 10 according to specific requirements, ensuring accuracy and consistency in the crimping process.

[0029] Through the continuous rotation of the rotary drive mechanism 3, each base 4 on the rotary disk 2 will pass through the crimping position in turn, realizing continuous automatic crimping operation with high work efficiency.

[0030] Specifically, the rotary drive mechanism 3 includes a rotary motor 31 fixedly mounted on the base plate 1. The output shaft of the rotary motor 31 is fixedly connected to a rotating rod 32. The top end of the rotating rod 32 is fixedly connected to the bottom center of the rotating disk 2. The rotary drive mechanism 3 rotates the rotating rod 32 by energizing the rotary motor 31, thereby rotating the rotating disk 2.

[0031] The clamping and fixing mechanism 6 includes two fixing blocks 61, which are symmetrically distributed on either side of the positioning slot 41 and fixedly connected to the base 4. Electric telescopic rods 62 are fixedly connected to opposite sides of the two fixing blocks 61. Arc-shaped clamping blocks 63 are fixedly connected to opposite ends of the two electric telescopic rods 62. Anti-slip pads 64 are fixedly connected to opposite sides of the two arc-shaped clamping blocks 63. After the rotor core 5 is placed in the positioning slot 41, the clamping and fixing mechanism 6 extends the electric telescopic rods 62 via the controller 10, driving the two arc-shaped clamping blocks 63 to move relative to each other and clamp the rotor core 5, thereby ensuring stability during crimping. Furthermore, the clamping and fixing mechanism 6 can accommodate rotor cores 5 of various sizes and facilitates installation and removal of the rotor core 5.

[0032] Example 2

[0033] See also Figure 4An electric push rod 11 is fixedly connected to the top center of the rotating disk 2. A bracket 12 is fixedly connected to the top of the electric push rod 11. A rubber sleeve 13 for clamping the rotor is provided on the bracket 12 corresponding to each base 4. The rotor is fixed to the bracket 12 through the rubber sleeve 13. By adding brackets 12 and rubber sleeves 13 to the rotating disk 2, the rotor can be prevented from falling off the rotor core 5 during the rotation of the rotating disk 2, which would affect the subsequent crimping work. The height of the bracket 12 can be adjusted by the electric push rod 11, which facilitates the removal of the crimped rotor and core and adapts to rotors of different heights.

[0034] Example 3

[0035] See also Figure 2 To ensure the stability of the rotating disk 2 during rotation, a circular chute 33 is provided at the bottom of the rotating disk 2, outside the rotating rod 32. Four evenly spaced sliders 34 are slidably connected within the circular chute 33. Each slider 34 is fixedly connected to a support rod 35 at its bottom, and the bottom end of the support rod 35 is fixedly connected to the base plate 1. The structure of the support rods 35 and sliders 34 provides auxiliary support for the rotating disk 2, effectively reducing the pressure exerted by the rotating disk 2 on the rotating rod 32. The combination of the circular chute 33 and sliders 34 ensures the normal rotation of the rotating disk 2.

[0036] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
