A lower stamping seat is provided at the bottom of each stamping hole, and a lower mounting plate is provided at the bottom of the lower stamping seat. A sound insulation pad is provided on the lower mounting plate. A connecting frame B connects the two lower mounting plates. A support frame A is mounted on the base, and a linear drive mechanism A for driving the connecting frame B is mounted on the support frame A. A guide plate is provided below each worktable. This invention has high working efficiency, good sound insulation, and strong practicality.

[0004] While the servo motor rotor lamination forming device in the aforementioned patent is practical and convenient, it also has shortcomings. General forming devices cannot automatically feed materials, which affects the efficiency of rotor processing. Furthermore, the clamping mechanism in the rotor forming device of the prior art is prone to damaging the rotor during the rotor forming process and cannot play a good role in fixing it, resulting in certain errors in the forming process. Utility Model Content

[0005] The purpose of this invention is to provide a motor rotor forming device to address the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The motor rotor forming device includes a frame, on which two clamping plates are horizontally slidably connected in reverse direction. A first slider is horizontally slidably connected to the frame. The sliding directions of the two clamping plates are perpendicular to the sliding direction of the first slider. A second slider is provided at the bottom of each of the two clamping plates. A second hinge seat is provided on one side of each of the two second sliders. A rocker arm is hinged within each of the two second hinge seats. A first hinge seat is hinged at the other end of each of the two rocker arms. An abutment block is provided on the side of each of the two first hinge seats that are close to each other. A mechanical gripper is rotatably connected to the top of the first slider. A pushing block is provided on both sides of the first slider. The two pushing blocks and the two abutment blocks are slidably connected in a one-to-one correspondence. A spring is provided between each abutment block and its corresponding pushing block. A driving assembly for driving the first slider to slide is provided on one side of the frame. An adjustment assembly for driving the mechanical gripper to rotate 180 degrees is provided inside the frame.

[0007] Furthermore, the adjustment assembly includes a connecting column, a gear, and a rack meshing with the gear. The rack is disposed within the frame.

[0008] Furthermore, the drive assembly includes a motor and a screw, a first slide groove is horizontally provided on the frame, the first slider is slidably connected in the first slide groove, the screw is rotatably connected in the first slide groove, the screw is screwed to the first slider, and the output end of the motor is coaxially and fixedly connected to one end of the screw.

[0009] Furthermore, two guide grooves are symmetrically provided inside the frame, and a guide rod is horizontally provided in each of the two guide grooves. The two guide rods are sleeved with the two springs in a corresponding manner, the two guide rods are slidably sleeved with the two push blocks in a corresponding manner, and the two guide rods are slidably sleeved with the two abutting blocks in a corresponding manner.

[0010] Furthermore, a rubber pad is provided on the side of each of the two clamping plates that are close to each other.

[0011] Compared with the prior art, the beneficial effects provided by this utility model are as follows: The motor rotor forming device uses mechanical grippers to hold the rotor to be processed and move it horizontally.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-6The present invention provides a technical solution: the rotor forming device for a motor 4 includes a frame 1, on which two clamping plates 2 are horizontally slidably connected in reverse direction, and a first slider 11 is horizontally slidably connected on the frame 1. The sliding directions of the two clamping plates 2 are perpendicular to the sliding direction of the first slider 11. A second slider 10 is provided at the bottom of each of the two clamping plates 2. A second hinge seat 18 is provided on one side of each of the two second sliders 10. A rocker arm 16 is hinged to each of the two second hinge seats 18. A first hinge seat 17 is hinged to the other end of each of the two rocker arms 16. The sides of the two first hinge seats 17 that are close to each other... A contact block 13 is provided. A mechanical gripper 3 is rotatably connected to the top of the first slider 11. A push block 12 is provided on both sides of the first slider 11. The two push blocks 12 are slidably connected to the two contact blocks 13 in a one-to-one correspondence. A spring 15 is provided between the two contact blocks 13 and the corresponding push blocks 12. A drive assembly for driving the first slider 11 to slide is provided on one side of the frame 1. An adjustment assembly for driving the mechanical gripper 3 to rotate 180 degrees is provided inside the frame 1. Specifically, two second slide grooves 9 are symmetrically opened on the frame 1. The two second sliders 10 are slidably connected to the two second slide grooves 9 in a one-to-one correspondence.

[0022] As a preferred technical solution, the adjustment assembly includes a connecting column 5, a gear 6, and a rack 7 meshing with the gear 6. The rack 7 is disposed inside the frame 1. The connecting column 5 is rotatably connected to the first slider 11. The bottom of the mechanical gripper 3 is fixedly connected to the top of the connecting column 5. The gear 6 is sleeved on the connecting column 5. Specifically, during the horizontal movement of the mechanical gripper 3 driven by the first slider 11, the meshing of the gear 6 and the rack 7 enables the connecting column 5 to drive the mechanical gripper 3 to rotate 180 degrees. This facilitates the mechanical gripper 3 to clamp the rotor to be processed from one side of the frame 1 and move it to the processing position, thereby achieving automatic feeding and improving processing efficiency.

[0023] As a preferred technical solution, the drive assembly includes a motor 4 and a screw 19. A first slide groove 8 is horizontally provided on the frame 1. A first slider 11 is slidably connected in the first slide groove 8. The screw 19 is rotatably connected in the first slide groove 8. The screw 19 is screwed to the first slider 11. The output end of the motor 4 is coaxially and fixedly connected to one end of the screw 19. Specifically, the motor 4 drives the screw 19 to rotate. The first slider 11 is guided and limited by the first slide groove 8, so that the screw 19 drives the first slider 11 to move along the length direction of the screw 19, thereby realizing that the mechanical gripper 3 drives the rotor to be processed to the processing position.

[0024] As a preferred technical solution, two guide grooves 20 are symmetrically provided inside the frame 1. A guide rod 14 is horizontally provided in each of the two guide grooves 20. The two guide rods 14 are sleeved with two springs 15 in a corresponding manner. The two guide rods 14 are slidably sleeved with two push blocks 12 in a corresponding manner. The two guide rods 14 are slidably sleeved with two abutment blocks 13 in a corresponding manner. Specifically, the guide rods 14 play a guiding and limiting role to prevent the springs 15 from bending and folding. When the first slider 11 drives the two push blocks 12 to move toward the two clamping plates 2, the springs 15 drive the two abutment blocks 13 to move toward the two clamping plates 2. The swing rod 16 drives the two clamping plates 2 to open, which can prevent the mechanical gripper 3 from colliding with the clamping plate 2 when rotating, thus avoiding motion interference.

[0025] As a preferred technical solution, a rubber pad is provided on the side of each of the two clamping plates that are close to each other, specifically to avoid clamping too tightly and damaging the rotor, thus affecting the rotor quality.

[0026] Working principle: The rotor forming device of motor 4 drives the screw 19 to rotate through the motor 4. The screw 19 drives the first slider 11 to move along the length of the screw 19. The mechanical gripper 3 clamps the rotor to be processed and moves it horizontally. The two abutment blocks 13 are driven by the spring 15 to move towards the two clamping plates 2. The swing rod 16 drives the two clamping plates 2 to open, and the operator can remove the processed rotor. This avoids collision between the mechanical gripper 3 and the clamping plate 2 when the mechanical gripper 3 rotates. The mechanical gripper 3 can rotate 180 degrees through the meshing of the gear 6 and the rack 7, so that the mechanical gripper 3 can clamp the rotor to be processed from one side of the frame 1 and move it to the processing position to realize automatic feeding and improve processing efficiency. In addition, the mechanical gripper 3 moves in the opposite direction and drives the two clamping plates 2 to clamp and fix the rotor through the swing rod 16, so as to avoid errors in rotor forming.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
