Description

Technical Field

[0001] This utility model relates to the field of motor processing technology, specifically to a stator anti-detachment gripper mechanism for motor processing. Background Technology

[0002] In modern industrial systems, electric motors, as core power components, are widely used in many fields such as new energy vehicles, smart homes, industrial automation equipment, and aerospace. As downstream industries continuously raise their performance requirements for motors, manufacturing precision and production efficiency have become key indicators of industry competitiveness. The stator, as the core component for electromagnetic energy conversion in a motor, directly determines the motor's power density, efficiency, and operational stability through its processing quality. Therefore, optimizing the stator processing technology has always been a key research direction in the field of motor manufacturing. In the stator processing flow, from stator core stacking and winding to subsequent insulation treatment, assembly and testing, the stator must be precisely positioned and stably clamped by a gripper mechanism to ensure the consistency of the processing benchmark for each process and avoid processing errors caused by stator position deviation. When the production line needs to switch to processing stators with different outer diameters, the original gripper assembly (including gripper body, mounting bracket, drive connector, etc.) must be completely disassembled and replaced with new grippers of the corresponding specifications. If there are differences in stator length, the distance between the upper and lower grippers also needs to be adjusted. Traditional adjustment methods require cumbersome operations such as adding or removing shims and recalibrating the installation reference. According to industry data, the changeover time of traditional grippers is generally 30-60 minutes per cycle, while the ideal changeover cycle of a flexible production line is required to be controlled within 5-10 minutes per cycle. Excessive changeover time causes the production line to stop and wait, which seriously reduces the overall production efficiency.

[0003] Therefore, a stator anti-detachment gripper mechanism for motor machining is proposed to address the above problems. Utility Model Content

[0008] As a further optimization of this utility model, the second gripper is located below the first gripper, and the movable tube is slidably connected to the outside of the mounting column, with the movable tube located above the second gripper.

[0009] As a further optimization of this utility model, the bottom of the rotating ball is rotatably engaged inside the rotating groove, the stabilizing rod passes through the inner wall of the movable tube, the positioning holes are evenly distributed in the side wall of the mounting column, and the stabilizing rod is adapted to the positioning holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, by using the movable tube, transmission rod, and rotating ball structure of the adjustment mechanism, when the movable tube slides along the mounting column, the rotating ball can rotate flexibly in the rotating groove, driving the second gripper to finely adjust its angle and height around the mounting column. At the same time, the even distribution of positioning holes on the side wall of the mounting column supports the selection of different locking positions for the stabilizing rod, realizing precise adjustment of the distance between the second gripper and the first gripper. It can adapt to stators with different outer diameters and lengths without replacing the entire gripper assembly, greatly improving the compatibility of the mechanism with the processing of multiple types of stators and adapting to the rapid switching requirements of flexible production lines.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0017] Please see Figures 1-6 This utility model provides a technical solution: A stator anti-detachment gripper mechanism for motor processing includes a slide rail 1 and an electric slider 2. An anti-detachment gripper body mechanism 3 is provided on the outside of the electric slider 2. The anti-detachment gripper body mechanism 3 includes a connecting plate 32. A mounting column 33 is fixedly connected between the connecting plates 32. A first gripper 34 and a second gripper 35 are installed on the outside of the mounting column 33. An adjustment mechanism 4 is provided between the second gripper 35 and the mounting column 33. The adjustment mechanism 4 includes a movable tube 41, an extension plate 42 fixedly connected to the outside of the movable tube 41, a transmission rod 43 fixedly connected to the bottom of the extension plate 42, a ball bearing 44 fixedly connected to the bottom of the transmission rod 43, a rotating groove 45 fixedly connected to the top of the second gripper 35, a guide tube 46 fixedly connected to the outside of the movable tube 41, a stabilizing rod 47 movably engaged inside the guide tube 46, a compression spring 48 sleeved on the stabilizing rod 47, and a positioning hole 49 opened in the side wall of the mounting column 33.

[0018] It should be noted that: the mounting posts 33 are symmetrically distributed inside the two connecting plates 32, the first clamp 34 and the second clamp 35 are symmetrically distributed outside the mounting posts 33, the second clamp 35 is located below the first clamp 34, the movable tube 41 is slidably connected to the outside of the mounting posts 33 and is located above the second clamp 35, the bottom of the rotating ball 44 is rotatably engaged inside the rotating groove 45, the stabilizing rod 47 passes through the inner wall of the movable tube 41, and the positioning holes 49 are evenly distributed in the side wall of the mounting posts 33, and the stabilizing rod 47 is compatible with the positioning holes 49. Furthermore: Cylinder 36 receives a reverse air pressure signal, and the output end pulls the connecting valve 37 to reset. After the gripper pusher 38 loses its thrust, it resets to the outside, simultaneously driving the first gripper 34 and the second gripper 35 to open to the outside, releasing the grip on the stator. The stator is then transferred to the next process by the subsequent conveying mechanism. Specifically: the electric slider 2 moves in the opposite direction along the slide rail 1, driving the anti-detachment gripper body mechanism 3 back to the initial standby position, waiting for the next clamping command, thus completing the entire work cycle; As a further implementation of this scheme, a fixed plate 31 is fixedly connected to the outside of the electric slider 2, and connecting plates 32 are symmetrically distributed on the outside of the fixed plate 31. A cylinder 36 is provided on the outside of the fixed plate 31, and a connecting valve 37 is fixedly connected to the output end of the cylinder 36. A gripper pusher 38 is provided on the outside of the first gripper 34 and the second gripper 35. A connecting pipe 410 is fixedly connected to the top of the second gripper 35, and a limit rod 411 is slidably engaged inside the connecting pipe 410. It should be noted that: cylinders 36 are symmetrically distributed on the outside of the fixed plate 31, gripper pusher 38 is located at one end of the two first grippers 34 and the two second grippers 35, the top of the limit rod 411 is fixedly connected to the bottom of the second gripper 35, and the first gripper 34 and the second gripper 35 have the same specifications. Workflow: When the motor processing production line issues a stator clamping command, the automated control system first outputs a displacement signal to the electric slider 2. Relying on the track support provided by the slide rail 1, the electric slider 2 moves linearly along the slide rail 1. The fixed plate 31 fixedly connected to its outer side and the anti-detachment gripper body mechanism 3 integrated on the plate move synchronously until the whole reaches the stator clamping position, such as the transfer position after the stator core is stacked and before the winding is wound, or the end forming processing position. During this process, the connecting plates 32 symmetrically distributed on the outer side of the fixed plate 31 and the mounting columns 33 fixed between the connecting plates 32 complete the initial position calibration synchronously with the mechanism, laying the foundation for the accurate clamping action in the future. After the initial positioning is completed, the mechanism immediately enters the power transmission stage: the cylinders 36, which are symmetrically distributed on the outside of the fixed plate 31, receive the air pressure control signal, and their output end pushes the connecting valve 37 to act. The connecting valve 37 transmits the power directly to the gripper pusher 38 through the air pressure pipeline, so that the gripper pusher 38 enters the ready-to-start state. Since the first gripper 34 and the second gripper 35 are exactly the same in specifications and are symmetrically distributed on the outside of the mounting column 33, and are also "distributed vertically", the two can naturally maintain the synchronization of their actions under the drive of the gripper pusher 38, thus avoiding the problem of clamping misalignment caused by differences in gripper specifications or asymmetrical distribution from the source. During the clamping action, the adjusting mechanism 4 simultaneously activates the stabilizing function. Due to the clamping action of the second gripper 35, the movable tube 41 and the mounting column 33 remain relatively stationary. The stabilizing rod 47 inside the outer guide tube 46 automatically engages with the positioning hole 49 at the corresponding position on the side wall of the mounting column 33 under the elastic thrust of the compression spring 48. The position of the movable tube 41 is locked through the "rod-hole engagement" structure. At the same time, the bottom bead 44 of the transmission rod 43 connected to the outer extension plate 42 of the movable tube 41 is precisely engaged in the rotating groove 45 at the top of the second gripper 35, further limiting the lateral displacement of the second gripper 35. This forms a dual stabilizing system of "longitudinal locking + lateral limiting". Even if slight vibration occurs during the processing, the elastic buffer of the compression spring 48 can offset part of the impact force in real time, always ensuring that the stator clamping posture is stable and the processing reference does not shift. The operator pulls the stabilizing rod 47 outward, compressing the spring 48 under external force. The stabilizing rod 47 disengages from the positioning hole 49, releasing the lock on the movable tube 41. The operator then pushes the movable tube 41 to slide up and down along the mounting post 33. The movable tube 41 drives the transmission rod 43 to move synchronously via the extension plate 42. The rotating ball 44 at the bottom of the transmission rod 43 rotates flexibly within the rotating groove 45 of the second gripper 35, smoothly converting the linear motion of the movable tube 41 into fine-tuning of the angle and height of the second gripper 35. During the adjustment of the second gripper 35, the connecting tube 4, fixed at its top... 10 always slides along the limit rod 411. The limit rod 411 provides precise vertical guidance for the second gripper 35, preventing the gripper from shifting laterally during adjustment. When the second gripper 35 is adjusted to a position that is fully compatible with the lower part of the stator to be processed, the stabilizing rod 47 is released, the compression spring 48 immediately resets and pushes the stabilizing rod 47 into the corresponding positioning hole 49, completing the adjustment and locking. The entire adjustment process only takes 1-2 minutes. Compared with the traditional gripper replacement time of more than 30 minutes, the tooling adjustment cycle is greatly shortened, perfectly adapting to the rapid switching needs of flexible production.
