Description

Technical Field

[0001] This application relates to the technical field of motor manufacturing tooling equipment, and in particular to a motor rotor reversing device and its reversing method. Background Technology

[0002] In the manufacturing of six-pole synchronous motors, in order to ensure good manufacturability and improve production efficiency, the rotor usually adopts a salient pole structure, and the magnetic pole and the shaft are designed as separate structures.

[0003] The magnetic pole consists of two main parts: the magnetic pole core and the magnetic pole coil. In the manufacturing process, the magnetic pole coil is first installed onto the magnetic pole core, followed by impregnation with varnish to enhance insulation performance and mechanical stability. Specifically, when installing the magnetic pole coil, the magnetic pole core is placed on a tray with the yoke facing down and the dovetail portion facing up. The magnetic pole coil is then placed onto the magnetic pole core, tightened, and then impregnated with varnish.

[0004] However, when installing the magnetic poles onto the shaft after the varnishing is complete, the dovetail portion of the magnetic poles must face downwards due to installation requirements. This means that the entire magnetic pole must be flipped.

[0005] Currently, the traditional magnetic pole flipping and hoisting process has significant drawbacks. This process mainly involves using a crane to hold one end of the magnetic pole, raising it upright, and then slowly lowering the crane in a dovetail-down direction to complete the flipping.

[0006] This process is not only time-consuming, taking approximately 20 minutes per rotation and incurring significant time costs, but it also requires close manual coordination with the crane, resulting in high labor intensity. More importantly, during this traditional lifting and rotating process, the magnetic pole coil is highly susceptible to collisions with surrounding objects, leading to deformation of the coil's heat sink. Deformation of the heat sink severely impacts the coil's heat dissipation, ultimately adversely affecting the motor's overall performance and lifespan. Summary of the Invention

[0007] To address the aforementioned technical problems, this application provides a motor rotor reversing device and its reversing method.

Detailed Implementation

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] Traditional magnetic pole 10 flipping and hoisting process, such as Figure 1 As shown, the process mainly involves using a crane to hold one end of the magnetic pole 10, raising the magnetic pole 10 upright, and then slowly controlling the crane to lower it in a dovetail-down direction to complete the flipping.

[0024] To address the problems associated with traditional magnetic pole 10 flipping and hoisting processes, this embodiment provides a motor rotor flipping device, such as... Figure 2 As shown, it includes a lifting platform 100, a sliding seat 200, a drive structure 300, and a tilting fixture 400.

[0025] The lifting platform 100 includes a counterweight base 110, a lifting column 120, and a connecting crossbar 130. The counterweight base 110 is used to ensure the stability of the entire tilting device. Preferably, rollers 111 are provided at the bottom of the counterweight base 110. The rollers 111 are preferably rollers with brakes. It should be noted that the rollers 111 are not a necessary structure, and the platform can be moved by a separate trolley during transportation without the rollers 111.

[0026] Two lifting columns 120 are provided, which are fixedly installed on the counterweight base 110 in the vertical direction. The two ends of the connecting crossbar 130 are fixedly connected to the top of the two lifting columns 120 respectively.

[0027] A sliding groove 121 is provided on the lifting column 120, and the sliding seat 200 is slidably installed in the sliding groove 121.

[0028] The drive structure 300 is used to control the lifting and lowering of the sliding seat 200. It includes a lifting screw 310 fixedly installed on the sliding seat 200, a lifting nut 320 rotatably installed on the lifting platform 100, and a drive element 330 for controlling the rotation of the lifting nut 320. The lifting screw 310 is threadedly connected to the lifting nut 320.

[0029] The drive element 330 can be an electric or manual structure, but since the flipping device needs to be moved frequently, in this embodiment the drive element 330 is a handwheel that is integrally connected with the lifting nut 320.

[0030] like Figure 2 and Figure 3As shown, two mounting arms 500 are mounted on the sliding seat 200. Each mounting arm 500 has a C-shaped opening 510 for inserting a flip tool 400. The opening end of the C-shaped opening 510 has a limiting structure 520 for restricting the flip tool 400 within the mounting arm 500. The inner wall of the C-shaped opening 510 has a mounting groove 530 that mates with the flip tool 400. By setting the mounting groove 530, the flip tool 400 can only be inserted along the opening direction of the C-shaped opening 510, and after insertion, it will not move or detach along the thickness direction of the flip tool 400.

[0031] The limiting structure 520 includes a limiting block 521 that is movably mounted on the mounting arm 500 in the horizontal direction, and an elastic reset member 522 for keeping the limiting block 521 in the limited state. Specifically, two limiting bolts 523 pass through the mounting arm 500 and are connected to the limiting block 521. The elastic reset member 522 is sleeved on the limiting bolts 523. The two ends of the elastic reset member 522 abut against the nuts of the limiting bolts 523 and the mounting arm 500, respectively, so that in the natural state, the limiting block 521 will block the mounting groove 530.

[0032] The movement direction of the limiting block 521 is perpendicular to the installation direction of the flipping fixture 400, and the movement of the limiting block 521 does not close the C-shaped opening 510, so as to avoid the limiting block 521 interfering with the magnetic pole 10 and making it impossible to install when the flipping fixture 400 with the magnetic pole 10 is installed.

[0033] The limiting block 521 is provided with a wedge-shaped surface 5211 that can be opened when the flip tool 400 is installed.

[0034] In addition, the limit block 521 is equipped with a handle to facilitate moving the limit block 521 when removing the flipping fixture 400.

[0035] With the above settings, the flipping fixture 400 can be installed on the mounting arm 500 in the horizontal direction, and when installed on the mounting arm 500, the flipping fixture 400 can rotate on the mounting arm 500.

[0036] Reference Figure 4 and Figure 5 The flip tool 400 is provided with a socket for inserting and circumferentially positioning the magnetic pole 10. The socket includes a central hole 410 and two dovetail holes 420. The two dovetail holes 420 are of different sizes and are located on both sides of the central hole 410. Both dovetail holes 420 are connected to the central hole 410. In this way, one flip tool 400 can be used to adapt to two different models of magnetic pole 10.

[0037] The aforementioned intermediate hole 410 and two dovetail holes 420 must be configured such that, when the magnetic pole 10 is installed on the flipping fixture 400, the center of gravity of the magnetic pole 10 deviates upward from the rotation axis of the flipping fixture 400, i.e. Figure 4 The state shown, after the flip is completed, is Figure 5 The state shown in the image indicates that the center of gravity is tilted downwards.

[0038] like Figure 1 As shown, a rack 140 is provided on the lifting platform 100. The length of the rack 140 is less than the height of the lifting platform 100 and it is located at the lower end of the lifting platform 100.

[0039] The flipping fixture 400 is equipped with external circular teeth 430 that can mesh with the rack 140. During the lifting and lowering process of the sliding seat 200, the flipping fixture 400 forms a free state and a meshing state based on the disengagement and engagement of the rack 140 and the external circular teeth 430, respectively. In the meshing state, the rack 140 and the external circular teeth 430 remain engaged. When the rack 140 and the external circular teeth 430 separate, it becomes free. In the free state, the flipping fixture 400 automatically flips via the center of gravity of the magnetic pole 10.

[0040] The purpose of setting the engagement state is to prevent damage to the magnetic pole 10 during the initial stage of the lifting process, when the flipping fixture 400 drives the magnetic pole 10 upwards. If the flipping fixture 400 is in a free state, it will be rotated by gravity, causing the magnetic pole 10 to collide with the tray. Therefore, by setting the engagement state, the initial lifting will only involve slow rotation driven by the engagement state. Only when the distance between the magnetic pole 10 and the tray reaches a safe distance will it enter a free state to complete the rapid flipping.

[0041] Specifically, the flipping method of the motor rotor flipping device with the above structure includes the following steps: S1. Install the magnetic pole 10. Remove the two flipping fixtures 400 from the mounting arm 500 and attach them to both ends of the magnetic pole 10 respectively. S2. Install the flip tool 400, adjust the height of the sliding seat 200 and the distance between the two flip tools 400, move the lifting platform 100 so that the two flip tools 400 are inserted into the two mounting arms 500 respectively, until the installation of the flip tool 400 is completed. S3. Adjust the height. The installation height of the mounting base to the magnet is adjusted by the drive structure 300. The installation height is higher than the height of the rack 140. After the outer circular tooth 430 separates from the rack 140, the flipping fixture 400 automatically flips under the gravity of the magnetic pole 10.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
