DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In order to solve the technical problem of manual loading and unloading (rotor) with high labor intensity, the utility model provides a rotor riveting machine, which can reduce labor intensity.

[0021] It should be noted that the rotor riveting machine described in the present invention is used for but not limited to processing rotors, etc. For the convenience of explanation, in the present invention, only the application of a rotor riveting machine to processing rotors is used as an example for explanation. The principle of applying a rotor riveting machine to other types of equipment is essentially the same as the principle applied to processing rotors, and will not be described in detail here.

[0022] See also Figure 1 , Figure 1 This is a structural schematic diagram of a rotor riveting machine in one embodiment of the present invention. A rotor riveting machine includes a press 1 and a central control component 2. The press 1 includes a front center platform 11 and a rear center platform 12. The central control component 2 is installed at the processing end of the press 1. The central control component 2 includes a rotating motor 21, a robotic arm 22 and a clamping hand 23. The rotating motor 21 is connected to one end of the robotic arm 22 and is used to drive the robotic arm 22 to switch positions between the front center platform 11, the processing end of the press 1 and the rear center platform 12. The clamping hand 23 is connected to the other end of the robotic arm 22.

[0023] In this embodiment, the clamping structure of the rotor 4 is formed by the setting of the clamping hand 23, and the setting of the rotating motor 21 and the mechanical arm 22 enables the rotor 4 to be switched at will among the three positions of the front center table 11, the processing end of the press 1 and the rear center table 12, thereby realizing automatic loading and unloading of the rotor 4 without the need for manual operation by workers, effectively reducing labor intensity.

[0024] Furthermore, the fixed end of the rotary motor 21 is fixedly connected to the press 1 , and the movable end of the rotary motor 21 is fixedly connected to the rotary table. The rotary motor 21 drives the rotary table to rotate, thereby driving the robotic arm 22 to rotate.

[0025] In one embodiment, see Figure 1 The central control assembly 2 also includes a lifting cylinder 24, which is connected to the robotic arm 22 and is used to drive the robotic arm 22 to move up and down.

[0026] In this embodiment, the gripper 23 uses a wide-type gripper cylinder as a driving part, and the two movable ends of the wide-type gripper cylinder are fixedly connected to the gripper 23. In order to prevent the thickness of the gripper 23 from colliding with the rotor 4 during rotation, a lifting cylinder 24 is required to drive the gripper 23 to rise, and then lower it to make the gripper 23 coplanar with the rotor 4, so that the gripper 23 can clamp the rotor 4.

[0027] Furthermore, in order to eliminate the need for the lifting cylinder 24 , the gripper 23 may be a flip-type mechanical claw, so that the gripper 23 can be coplanar with the mechanical arm 22 by flipping, thereby preventing the gripper 23 from colliding with the rotor 4 during rotation.

[0028] In one embodiment, see Figure 1 , also includes a moving component 3, the moving component 3 is connected to the front center platform 11, the moving component 3 includes a moving cylinder 31 and a push block 32, the moving cylinder 31 is connected to the push block 32, the moving cylinder 31 is used to drive the push block 32 to move and drive the rotor 4 on the front center platform 11 to move to the grasping position.

[0029] In this embodiment, the rotors 4 to be processed are placed one by one on the front center table 11 through an external conveyor line, and then the rotors 4 to be processed are moved one by one to the grasping position through the moving assembly 3 to facilitate grasping by the gripper 23.

[0030] Furthermore, the contact surface between the push block 32 and the rotor 4 to be processed is arc-shaped and matches the outer surface of the rotor 4, so that the rotor 4 can move more smoothly during the process.

[0031] In one embodiment, see Figure 1 A guide groove 111 is provided on the top of the front center platform 11, and the push block 32 moves back and forth along the length direction of the guide groove 111. The moving cylinder 31 is used to drive the push block 32 to move and drive the rotor 4 on the front center platform 11 to move along the length direction of the guide groove 111 to the grasping position.

[0032] In this embodiment, the width of the guide groove 111 is the same as the outer diameter of the rotor 4 , so that the rotor 4 will not deviate during the movement.

[0033] In one embodiment, see Figure 1 The top of the front center platform 11 is fixedly connected with a slide rail 112 , the length direction of the slide rail 112 is parallel to the length direction of the guide groove 111 , and the bottom of the push block 32 is slidably embedded in the slide rail 112 .

[0034] In this embodiment, a sliding groove is provided at the bottom of the push block 32 , and the sliding groove is slidably embedded in the slide rail 112 , so that the push block 32 is more stable during the movement.

[0035] In one embodiment, see Figure 1 A fixing plate 113 is fixedly connected to the top of the front center platform 11 , and the fixing plate 113 is connected to the moving cylinder 31 .

[0036] In this embodiment, the function of the fixed plate 113 is to install the moving cylinder 31. The fixed end of the moving cylinder 31 is fixedly connected to the fixed plate 113. The movable end of the moving cylinder 31 passes through the fixed plate 113 and extends toward the rotating motor 21. After the external conveyor line conveys the rotor 4 to be processed to the front center table 11, the power generated by the moving cylinder 31 pushes the rotor 4 to be processed to the grasping position on the front center table 11.

[0037] In one embodiment, see Figure 1 There are three robotic arms 22 , and each robotic arm 22 is circumferentially installed at the movable end of the rotating motor 21 at equal intervals.

[0038] In this embodiment, there are three robotic arms 22, and each robotic arm 22 is arranged at equal intervals. Each robotic arm 22 is fixedly connected to the rotating table at the movable end of the rotating motor 21, so that the robotic arm 22 can simultaneously complete loading and unloading once every 120° rotation, effectively improving the processing efficiency of the rotor 4.

[0039] It should be noted that in order to match the three robotic arms 22, the distances between the grabbing position on the front center table 11, the processing end of the press 1 and the three positions of the rear center table 12 are equal, so that the robotic arms 22 can simultaneously complete the loading and unloading of the rotor 4 every time they rotate 120°.

[0040] In one embodiment, see Figure 1 The contact surface between the clamping hand 23 and the rotor 4 is arc-shaped.

[0041] In this embodiment, the two opposite contact surfaces of the clamping hands 23 that contact the rotor 4 are both arc-shaped and match the outer surface of the rotor 4 , so that the clamping hands 23 can clamp the rotor 4 more stably.

[0042] In one embodiment, see Figure 1 The top of the rear center platform 12 is fixedly connected to the limiting platform 121.

[0043] In this embodiment, the function of the limit platform 121 is to temporarily store the rotor 4 after riveting, and under the action of the limit platform 121, the processed rotor 4 cannot move, thereby avoiding the vibration generated by the operation of the press 1 causing the rotor 4 on the rear center platform 12 to fall off, making it easier for the processed rotor 4 to wait for the next step.

[0044] In one embodiment, see Figure 1 A lifting cylinder 13 is installed at the bottom of the processing end of the press 1.

[0045] In this embodiment, the function of the lifting cylinder 13 is to push out the rotor 4 after the riveting is completed, so as to facilitate the gripping of the gripper 23.

[0046] In order to better understand the present invention, the following Figure 1 The technical solution of the utility model is described in detail:

[0047] First, the rotor 4 to be processed is placed on the front center table 11 through an external conveyor line; then, the moving cylinder 31 and the push block 32 are used to drive the rotor 4 to be processed to move along the guide groove 111 to the grabbing position; secondly, the lifting cylinder 24 descends, and the clamp 23 grabs the rotor 4 to be processed; then, the rotary motor 21 rotates, and the robotic arm 22 drives the rotor 4 to be processed to the processing end of the press 1; then, the press 1 presses down, and before the press 1 presses down, the clamp 23 needs to release the rotor 4, and the robotic arm 22 rises and rotates a certain angle to make room for the press 1 to press down; finally, the lifting cylinder 13 pushes out the processed rotor 4, and the robotic arm 22 resets, clamps the processed rotor 4 again and moves it to the rear center table 12, completing the riveting. This device realizes automatic loading and unloading of the rotor 4 without manual operation, effectively reducing labor intensity.

[0048] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model.
