[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1-4 The grinding machine produced from the high-voltage motor housing offers two technical solutions:

[0023] The first embodiment includes a base plate 1 and an outer frame 2 fixed to the top of the base plate 1. A moving mechanism 3 is provided on the outer frame 2, and a grinding component 4 is installed on the moving mechanism 3. The moving mechanism 3 is used to drive the grinding component 4 to move on the X-axis, Y-axis and Z-axis. A detection component 8 is provided on the grinding component 4, and the detection component 8 is used to cooperate with the grinding component 4 to move along the arc surface of the high-voltage motor housing. A fixing mechanism is provided on the base plate 1, and the fixing mechanism is used to fix the high-voltage motor housing.

[0024] The fixing mechanism includes a push assembly 5, an inner support assembly 6, and a drive assembly 7 arranged symmetrically on the left and right. The push assembly 5 is used to push the inner support assembly 6 to move in order to fix the high voltage motor housing of different lengths. The inner support assembly 6 includes a disc 61. Multiple first sliding grooves 62 are equally spaced inside the disc 61, and arc-shaped plates 63 are slidably connected to the inner surfaces of the multiple first sliding grooves 62. Guide rods 64 are fixedly connected to the other side of the multiple arc-shaped plates 63. The drive assembly 7 is used to drive the multiple arc-shaped plates 63 to move.

[0025] The pushing component 5 includes a support plate 51, which is fixedly connected to the top of the base plate 1. A first hydraulic cylinder 52 is fixedly connected to one side of the support plate 51, and the telescopic end of the first hydraulic cylinder 52 is fixedly connected to one side of the disc 61.

[0026] The drive assembly 7 includes a circular ring plate 71, which is slidably connected to one side of the disc 61. The circular ring plate 71 has multiple guide grooves 72 that are equidistant from each other, the same number as the first sliding groove 62. Multiple guide rods 64 are respectively located in the guide grooves 72 at corresponding positions. The surface of the telescopic rod of the first hydraulic cylinder 52 is fixedly connected to a drive motor 73 via a bracket. The output end of the drive motor 73 is fixedly connected to a drive gear 74. The inner surface of the circular ring plate 71 has multiple toothed grooves 75 that are equidistant from each other, and the drive gear 74 meshes with the toothed grooves 75.

[0027] When grinding a high-voltage motor, the housing is fixed by a fixing mechanism, which ensures the stability of the housing during grinding. The fixing mechanism is applicable to housings of different lengths and diameters, improving the practicality of the device.

[0028] The second embodiment differs from the first embodiment in that the moving mechanism 3 consists of a lead screw assembly, a gear and rack assembly, and a hydraulic cylinder assembly. The lead screw assembly moves along the X-axis, the gear and rack assembly moves along the Y-axis, and the hydraulic cylinder assembly moves along the Z-axis. The grinding assembly 4 is fixedly mounted on the hydraulic cylinder assembly. The detection assembly 8 includes a fixed plate 81 and a distance sensor 82. A controller 9 is mounted on the outer frame 2, and the distance sensor 82 is connected to the controller via a signal connection. The fixed plate 81 is fixedly connected to the left side of the grinding assembly 4. A second sliding groove 83 is provided inside the fixed plate 81. A bolt 84 is fixedly connected to the top of the distance sensor 82, and the bolt 84 passes through the second sliding groove 83. A nut 85 is threaded onto the surface of the bolt 84 on the fixed plate 81.

[0029] When the shell is polished by the polishing component 4, the moving mechanism 3 and the distance sensor 52 work together to move the polishing component 4 along the Y and Z axes and match the arc-shaped shell, so that the shell is polished more thoroughly.

[0030] In use, the high-voltage motor housing is placed in the middle, and the two first hydraulic cylinders 52 are activated, so that the housing is fitted onto the outside of the four arc-shaped plates 63 on both sides. The drive motor 73 is activated, causing the drive gear 74 to rotate. The rotation of the drive gear 74, through the engagement of the tooth groove 75, causes the ring plate 71 to rotate. The rotation of the ring plate 71, through the engagement of the guide groove 72 and the guide rod 64, causes the multiple arc-shaped plates 63 to expand outward, thereby providing internal support and fixation for the high-voltage motor housing. During grinding, as the grinding assembly 4 moves along the Y-axis, the distance sensor 82 detects the distance between the grinding assembly 4 and the housing. While the grinding assembly 4 moves along the Y-axis, the hydraulic cylinder assembly controls the up and down movement of the grinding assembly 4, thereby grinding the housing along the arc surface.
