Abstract
Description
Technical Field
[0001] This utility model relates to the field of permanent magnet synchronous motor manufacturing technology, and in particular to a rotary clamping device for stator winding management of a low-speed, high-torque permanent magnet synchronous motor. Background Technology
[0002] Using a low-speed, high-torque permanent magnet synchronous motor drive system can eliminate the need for an external reducer, reduce intermediate transmission links, improve the safety and reliability of the system, and reduce environmental pollution and spare parts consumption. Low-speed, high-torque permanent magnet synchronous motors are widely used in the machinery equipment manufacturing industry, heavy machinery industry, and other fields.
[0003] During the manufacturing of low-speed, high-torque permanent magnet synchronous motors, copper wire is wound around the stator winding using copper wire winding equipment. After winding, these copper wires need to be manually arranged. During the arrangement process, the arrangement area needs to be changed frequently. Therefore, the stator winding needs to be effectively clamped from the inside during the wire arrangement process to avoid excessive compression caused by external clamping and affecting the wire arrangement work. At the same time, it is also necessary to meet the requirements for switching between wire arrangement areas. Therefore, a rotary clamping device is needed to ensure the clamping effect while facilitating the switching of working areas and reducing the danger of equipment use. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a rotary clamping device for managing the stator windings of a low-speed, high-torque permanent magnet synchronous motor.
[0005] This utility model is achieved through the following technical solution:
[0006] A rotary clamping device for stator winding management of a low-speed, high-torque permanent magnet synchronous motor includes a mounting base, a motor plate, a motor, a drive gear, a shielding ring, a fixing mechanism, and a mounting shaft. The motor plate is fixedly disposed on the outside of the mounting base, the motor is mounted on the bottom of the motor plate, the drive gear is mounted on the output end of the motor, the shielding ring is connected to the top of the mounting base, the mounting shaft is fixedly disposed on the inner side of the bottom of the mounting base, and the fixing mechanism is movably connected to the mounting shaft. The fixing mechanism includes a rotating disk, a gear ring, a mounting bracket, a hydraulic cylinder, an inner support seat, and a guide rod. The gear ring is fixedly disposed on the outside of the rotating disk, the mounting bracket is fixedly mounted on the top of the rotating disk, the hydraulic cylinder is mounted on the inner side of one end of the mounting bracket, the inner support seat is fixedly disposed on the telescopic end of the hydraulic cylinder, and the guide rod is fixedly disposed on the inner side of the inner support seat.
[0007] In a preferred embodiment of the present invention, one end of the guide rod passes through and extends into the interior of one side of the mounting bracket, and a guide hole that cooperates with the guide rod is provided on the side of the mounting bracket.
[0008] Since the inner support seat only provides single-point support at the connection point between the hydraulic cylinder and the inner support seat when supporting the inner side of the motor stator winding, the stability of the inner support seat is poor, which affects the support and fixing effect. Setting a guide rod can effectively ensure that the inner support seat runs horizontally and improve the clamping stability.
[0009] In a preferred embodiment of the present invention, a support bar is provided on the top of one side of the inner support seat, a friction groove is provided on the outer side of the support bar of the inner support seat, and a guide card is also provided on the inner side of the inner support seat.
[0010] In a preferred embodiment of this utility model, the inner guide card of the inner support is engaged on the top of the mounting frame, and the top of the mounting frame is provided with a guide slot that cooperates with the guide card.
[0011] Similar to the guide rods mentioned above, the guide card set on the inner side of the inner support is locked in the guide slot at the top of the mounting bracket. This effectively guides the movement of the inner support while preventing it from tilting under stress, thus ensuring effective support inside the motor stator winding.
[0012] In a preferred embodiment of the present invention, a mounting hole is provided on the outer side of the mounting base, one end of the drive gear passes through and extends into the interior of one side of the mounting base, and the drive gear cooperates with the gear ring.
[0013] When the motor starts, the drive gear rotates the gear ring, which in turn rotates the fixed stator winding, thus enabling the switching of processing areas and facilitating the copper wire arrangement work.
[0014] In a preferred embodiment of the present invention, a connecting ring is provided at the bottom of the rotating disk, the bottom connecting ring of the rotating disk is movably connected to the mounting shaft, and a shielding ring is provided on the outer side of the top of the toothed ring.
[0015] The beneficial effects of this utility model are:
[0016] This low-speed, high-torque permanent magnet synchronous motor stator winding wire management rotary clamping device supports and tensions the inner side of the motor stator winding with copper wire, thereby effectively and stably fixing the stator winding from the inside. Furthermore, the stator winding can be slowly rotated by the motor rotation, allowing for quick switching of the working area and facilitating wire management. The gear connection position is effectively shielded, preventing the copper wire from falling and being squeezed and damaged by the gear connection position. At the same time, it also prevents workers from coming into contact with the meshing position, improving the safety of equipment use. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.
[0022] like Figure 1-3 The rotating clamping device for stator winding management of a low-speed, high-torque permanent magnet synchronous motor, shown, includes a mounting base 1, a motor plate 2, a motor 3, a drive gear 4, a shielding ring 5, a fixing mechanism 6, and a mounting shaft 7. The motor plate 2 is fixedly disposed on the outside of the mounting base 1, the motor 3 is mounted on the bottom of the motor plate 2, the drive gear 4 is mounted on the output end of the motor 3, the shielding ring 5 is connected to the top of the mounting base 1, the mounting shaft 7 is fixedly disposed on the inner side of the bottom of the mounting base 1, and the fixing mechanism 6 is movably connected to the mounting shaft 7. The fixing mechanism 6 includes a rotating disk 61, a gear ring 62, a mounting bracket 63, a hydraulic cylinder 64, an inner support seat 65, and a guide rod 66. The gear ring 62 is fixedly disposed on the outside of the rotating disk 61, the mounting bracket 63 is fixedly mounted on the top of the rotating disk 61, the hydraulic cylinder 64 is mounted on the inner side of one end of the mounting bracket 63, the inner support seat 65 is fixedly disposed on the telescopic end of the hydraulic cylinder 64, and the guide rod 66 is fixedly disposed on the inner side of the inner support seat 65.
[0023] Specifically, one end of the guide rod 66 passes through and extends into the interior of one side of the mounting bracket 63. The side of the mounting bracket 63 has a guide hole that mates with the guide rod 66. A support bar is provided on the top of one side of the inner support seat 65. A friction groove is provided on the outer side of the support bar of the inner support seat 65. A guide card is also provided on the inner side of the inner support seat 65. The guide card on the inner side of the inner support seat 65 is locked onto the top of the mounting bracket 63. A guide slot that mates with the guide card is provided on the top of the mounting bracket 63. An installation hole is provided on the outer side of the mounting base 1. One end of the drive gear 4 passes through and extends into the interior of one side of the mounting base 1. The drive gear 4 mates with the gear ring 62. A connecting ring is provided at the bottom of the rotating disk 61. The connecting ring at the bottom of the rotating disk 61 is movably connected to the mounting shaft 7. A shielding ring 5 is provided on the outer side of the top of the gear ring 62.
[0024] In this embodiment, the motor stator winding that needs to be arranged for copper wire is first placed on the top of the mounting bracket 63. Then, the hydraulic cylinder 64 is controlled to retract, causing the inner support 65 fixed at the extension end of the hydraulic cylinder 64 to move backward. The support bar on the top side of the inner support 65 contacts the inner side of the stator winding. Since the top of the rotating disk 61 is uniformly arranged with three fixing mechanisms 6 in a ring shape, the stator winding can be automatically positioned and fixed. The back of the inner support 65 is provided with a guide card and a guide rod 66. The guide card is locked in the guide slot at the top of the mounting bracket 63, thus ensuring that the inner support 65 moves horizontally in a vertical state, ensuring the support and fixing effect on the stator winding.
[0025] Furthermore, during wire processing, the worker turns on the motor 3 to slowly rotate the drive gear 4 at its output end. The drive gear 4 meshes with the toothed ring 62 on the outer side of the rotating disk 61, thereby causing the rotating disk 61 to slowly rotate around the connection position between the bottom connecting ring and the mounting shaft 7, realizing the switching of processing areas. A shielding ring 5 is installed on the top of the mounting base 1 by screws to cover the meshing position of the drive gear 4 and the toothed ring 62 and the top of the toothed ring 62, preventing the falling copper wire from getting caught in the meshing position, and at the same time preventing the worker from contacting the meshing position and causing injury, thus improving the safety of equipment use.
