[0002] The motor rotor is usually composed of an iron core and a winding. The main function of the motor rotor is to rotate under the action of an electromagnetic field, thereby driving the mechanical equipment to operate.

[0003] During the motor rotor processing, after the high-impact process, a large number of burrs or burrs will be generated inside the winding groove. When removing the burrs, the existing equipment usually uses a grinding device to grind the grooves on the surface of the motor rotor after milling to facilitate the subsequent winding. However, the grooves on the outside of the motor rotor are arc-shaped. The existing grinding equipment is difficult to grind the inside or corners of the grooves, and it is difficult to grind the grooves in all directions without dead angles, which is inconvenient to use.

[0004] In view of the above-mentioned existing technical problems, a motor rotor surface processing mechanism is proposed to solve them. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] See also Figure 1-4 A motor rotor surface processing mechanism in this embodiment includes a motor 1 as a driving element and a mounting frame 2 connected to the motor 1. A connecting frame 3 is fixedly connected to the power end of the motor 1, and the connecting frame 3 and the mounting frame 2 are movably connected.

[0025] Specifically, an arc-shaped insertion rod 4 extends from the end of the connecting frame 3, and a hole 5 corresponding to the insertion rod 4 is penetrated through the circumference of the mounting frame 2. The insertion rod 4 passes through the hole 5, so that the mounting frame 2 can adjust its position by sliding relative to the insertion rod 4.

[0026] It is additionally explained that nuts 6 are installed on the external threads of the insertion rod 4 , and the nuts 6 include two nuts located on both sides of the mounting frame 2 . The mounting frame 2 can be positioned relative to the insertion rod 4 through the two nuts 6 .

[0027] In this embodiment, a connecting structure is provided on the inner side of the mounting frame 2, and a grinding roller 9 located on the inner side of the mounting frame 2 is installed through the connecting structure. Through the traction of the motor 1, the grinding roller 9 can grind the surface of the motor rotor.

[0028] It should be noted that the connection structure includes a slide bar 8 slidably mounted on the mounting frame 2 , an assembly frame for mounting the grinding roller 9 and connected to the slide bar 8 , and a spring 16 located on the assembly frame.

[0029] In a specific implementation, the spring 16 can push the grinding roller 9 to fit the motor rotor surface for grinding, and the grinding roller 9 can be pushed by the spring 16 to extend into the arc-shaped groove on the motor rotor surface to grind the burrs.

[0030] Preferably, sliding holes 7 for sliding the sliding rods 8 are provided at equal distances on the outer wall of the mounting frame 2, and the cross-sections of the sliding rods 8 and the sliding holes 7 are both rectangular.

[0031] This design can prevent the slide bar 8 from rotating relative to the mounting bracket 2 .

[0032] In this embodiment, the assembly frame includes connecting plates 11 connected to both sides of the grinding roller 9 and a fixing plate 15 fixedly connected to the two connecting plates 11 , wherein the outside of the grinding roller 9 is fixedly connected with a latch 10 plugged into the connecting plates 11 .

[0033] Preferably, a recessed groove 12 is provided on the outer wall of the latch 10, and a raised portion 13 corresponding to the recessed groove 12 is raised on the hollow inner wall of the connecting plate 11. The raised portion 13 slides relative to the recessed groove 12, thereby improving the insertion stability of the latch 10 relative to the connecting plate 11.

[0034] In this embodiment, a plug 14 is fixedly installed on the top of the connecting plate 11, and the plug 14 is inserted into the fixing plate 15 and is threadedly connected to the plug 14 by bolts, so that the fixing plate 15 and the connecting plate 11 can be assembled, wherein the fixing plate 15 is fixedly connected to the sliding rod 8.

[0035] Such a design enables the grinding roller 9 installed between the connecting plates 11 to be easily disassembled and installed, so that the grinding roller 9 of different sizes can be replaced according to the size of the motor rotor to be ground.

[0036] It should be noted that spring seats 17 are fixedly mounted on the surface of the fixing plate 15 and the inner wall of the mounting frame 2 , and both ends of the spring 16 are fixedly connected to the two spring seats 17 respectively.

[0037] A limiting plate 18 is fixedly mounted on one end of the slide bar 8 extending through the outside of the mounting frame 2 in this embodiment, and the limiting plate 18 can prevent the slide bar 8 from being separated from the sliding connection with the mounting frame 2.

[0038] The working principle of the above embodiment is:

[0039] By extending the motor rotor to the inside of the mounting frame 2, the grinding roller 9 installed on the inner side of the mounting frame 2 through the slide rod 8 is pushed by the spring 16 to fit on the surface of the motor rotor. The mounting frame 2 and the insertion rod 4 are plugged into and connected with each other and fixed by the nut 6. Then, the motor 1 can be controlled to drive the connecting frame 3 connected to its power end to rotate. The connecting frame 3 drives the mounting frame 2 to rotate synchronously under the rotation. The grinding roller 9 in the mounting frame 2 rolls along the surface of the motor rotor to grind the burr part. When the grinding roller 9 rolls to the groove on the surface of the motor rotor, it is pushed by the spring 16 and can fit on the groove surface of the motor rotor for grinding.
