[0037] See also Figure 3 and Figure 8 As shown, compared with Example 1, as another embodiment of the present invention, four groups of clamping blocks 54 are welded and fixed on both sides of the lifting plate 25, and the clamping blocks 54 are slidably connected to the inside of the clamping groove 55, and the clamping groove 55 is opened on the inner wall of the through groove 40;

[0038] During operation, as the lifting plate 25 moves upward, the blocks 54 fixed on the left and right sides of the lifting plate 25 will slide within the range of the slot 55, thereby limiting the rising height of the lifting plate 25 and ensuring that the lifting plate 25 moves within a normal range. At the same time, the movement of the lifting plate 25 can be made more stable through the contact between the blocks 54 and the inner wall of the slot 55.

[0042] During operation, when the moving platform 38 moves, four sets of moving wheels 45 are used to assist in supporting the bottom end of the moving platform 38 so that the moving platform 38 can move more smoothly.

[0043] See also Figure 3 , Figure 4 and Figure 6 As shown, a rectangular groove 58 is provided on one side of the first moving block 28 and the second moving block 29 away from the threaded rod 46, and a top plate 57 is welded and fixed to both sides of the inner wall of the chamber 41, and the rear end of the top plate 57 is trapezoidal in design;

[0044] During operation, two sets of top plates 57 are fixed on the inner wall of the chamber 41. When the first moving block 28 and the second moving block 29 contact each other and move on the threaded rod 46, the top plates 57 will abut against the rectangular groove 58, so that the contact between the first moving block 28 and the second moving block 29 can be closer through the top plates 57, so as to ensure the stable movement of the first moving block 28 and the second moving block 29 on the threaded rod 46, wherein the fixed position of the top plate 57 is below the support rod 42 and does not contact the bottom end of the support rod 42 to avoid abutting against the support rod 42.

[0045] See also Figure 1 As shown, the left and right sides of the fixing frame 20 are fixedly connected with the columns 60, one side of the fixing frame 20 and the column 60 is in contact with the plastic plate 61, the plastic plate 61 is fixedly connected with the fixing frame 20 and the column 60, and the plastic plate 61 is provided with a plurality of groups of circular holes, and the bottom ends of the column 60 and the plastic plate 61 are not in contact with the top end of the fixing rod 50;

[0046] During operation, the plastic plate 61 is fixed to the fixing frame 20 and the plastic plate 61 by screws to facilitate installation and disassembly, and a plurality of groups of round holes are provided on the plastic plate 61 to facilitate normal air circulation. The bottom ends of the column 60 and the plastic plate 61 do not contact the fixing rod 50 to ensure normal rotation of the fixing rod 50 on the press body 1.

[0047] See also Figure 1 As shown, a cover 63 is fixedly connected to the plastic plate 61, and the cover 63 is sleeved on the outer side of the fixed rod 50;

[0048] During operation, when the fixing rod 50 rotates to the sleeve 63, the sleeve 63 can protect the fixing rod 50 to ensure that the fixing rod 50 will not be bumped by the outside.

[0049] Working principle: After the hot pressing structure 21 completes the hot pressing of the motor housing 64 and the motor stator, the servo motor 59 is started to drive the moving platform 38 to move on the press body 1, so that the motor housing 64 is moved out from the bottom end of the hot pressing structure 21, so as to facilitate the removal of the motor housing 64. First, after the hot pressing structure 21 located directly above the motor housing 64 completes the hot pressing of the motor housing 64 and the motor stator, the hot pressing structure 21 will automatically lift upward, and the connecting rod 22 fixedly connected to the rear end of the hot pressing structure 21 will also move with the hot pressing. The structure 21 is lifted synchronously. Since the long rod 24 is inserted into the interior of the connecting rod 22 and the long rod 24 and the connecting rod 22 are connected by the fixing spring 23, when the connecting rod 22 is lifted to a certain height, it can drive the lifting plate 25 to move upward. When the top block 26 fixed at the bottom end of the lifting plate 25 is no longer in contact with the inclined groove 27, under the action of the connecting spring 31 in the spring groove 30, the first moving block 28 and the second moving block 29 will move closer to the threaded rod 46 and mesh with the threaded rod 46. At this time, the servo motor 59 is driven to drive the threaded rod 46 to move upward. The threaded rod 46 rotates, and the first moving block 28 and the second moving block 29 can move forward through the threaded connection with the threaded rod 46, and the protrusions 34 fixed on the top of the first moving block 28 and the second moving block 29 contact the inner wall of the connecting block 35. Therefore, when the first moving block 28 and the second moving block 29 move, the connecting block 35 can be driven to move together, thereby driving the moving platform 38 to move, and the motor housing 64 placed on the moving platform 38 will be taken out, so that the motor housing 64 is easy to take, wherein the top block 26 The bottom end is trapezoidal in design to facilitate pushing the first moving block 28 and the second moving block 29 apart. Slide blocks 36 are fixed on the left and right sides of the connecting block 35. The sliding of the slide blocks 36 in the slide grooves 39 provides support for the moving platform 38. A notch 37 is provided on the rear end of the connecting block 35 to prevent the connecting block 35 from abutting against the lifting plate 25 and the top block 26. A plug post 32 is fixed on the second moving block 29, and the plug post 32 is inserted in the slot 33, so as to make the connection between the first moving block 28 and the second moving block 29 more stable.

[0050] Through the structural design of the clamping assembly, during the movement of the moving platform 38, the two groups of clamping plates 43 on the moving platform 38 will approach each other until the motor housing 64 is clamped, so as to clamp and fix the motor housing 64, ensuring that the motor housing 64 will not fall off the moving platform 38 when the moving platform 38 is transporting the motor housing 64. When the first moving block 28 and the second moving block 29 contact each other under the action of the two groups of connecting springs 31, the support rod 42 fixed on the first moving block 28 and the second moving block 29 will also approach each other, and the clamping plate 43 fixedly connected to the top end of the support rod 42 can approach the motor housing 64 and clamp and fix the motor housing 64, so that the motor housing 64 can remain stable when the moving platform 38 is transporting the motor housing 64, wherein the clamping plate 43 is designed in an arc shape to increase the contact area with the surface of the motor housing 64, so that the clamping effect of the clamping plate 43 on the motor housing 64 is better.

[0051] Through the structural design of the cleaning mechanism, when the movable platform 38 drives the motor housing 64 to move out from the bottom end of the hot pressing structure 21, the worm 47 will drive the rotating wheel 49 to rotate through the worm gear 48. When the fixed rod 50 fixed on the rotating wheel 49 rotates, the brush plate fixed on the bottom end of the fixed rod 50 can clean the top of the press body 1 to keep the top of the press body 1 clean and reduce subsequent cleaning operations. When the threaded rod 46 rotates, the worm 47 fixedly connected to the rear end of the threaded rod 46 will also rotate synchronously. Therefore, the worm 47 can drive the worm gear 48 meshing with it to rotate, and the worm gear 48 drives the rotating wheel 49 to rotate by meshing with the rotating wheel 49. The rotating wheel 49 can drive the fixed rod 50 to rotate, and the brush plate fixed on the bottom end of the fixed rod 50 can clean the surface of the press body 1. The bottom end of the fixed frame 20 is also provided with an arc groove 62 to ensure that the fixed rod 50 will not abut against the fixed frame 20 during rotation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
