The mounting bracket 13 cooperates with the mounting through hole 14 and fixing parts such as bolts to fix the position of the base plate 1, thereby increasing the overall stability of the device when in use.

[0025] The output end of the power of the rotating motor 3 passes through the support plate 2 and is fixedly connected to a reciprocating screw 4. The outer surface of the reciprocating screw 4 is threadedly connected to a grinding frame 5. The interior of the grinding frame 5 is clamped with equidistantly arranged clamping plates 6. The right side of the support plate 2 is fixedly connected to a stabilizing block 15. The bottom surface of the stabilizing block 15 is fixedly connected to the upper surface of the base plate 1.

[0026] A grinding strip 7 is fixedly connected to the outer surface of each clamping plate 6, and a stator tube 8 and two limit sleeves 9 are respectively sleeved on the outer surface of the grinding frame 5. The outer surface of each grinding strip 7 contacts the inner wall of the stator tube 8 and the inner wall of the two limit sleeves 9. A positioning bolt 16 is threadedly connected to the interior of each clamping plate 6. One end of each positioning bolt 16 close to the grinding frame 5 passes through the clamping plate 6 and extends to the interior of the grinding frame 5. Each positioning bolt 16 is threadedly connected to the grinding frame 5. The positioning bolt 16 can be used to locate the position of the clamping plate 6 inside the grinding frame 5 to prevent the clamping plate 6 from sliding, thereby increasing the reliability of the clamping plate 6 and the grinding strip 7.

[0027] The outer surface of one of the limit sleeves 9 is fixedly connected to two support frames 10, and the left side surface of each support frame 10 is fixedly connected to the right side surface of the support plate 2. The inside of the grinding frame 5 is slidably connected to two limit columns 17, and the left end of each limit column 17 is fixedly connected to the right side surface of the support plate 2. The limit columns 17 can share the pressure of the reciprocating screw 4 and also limit the movement trajectory of the grinding frame 5 so that it can only slide left and right and will not rotate with the rotation of the reciprocating screw 4.

The threaded connection between the pinion 25 and the gear barrel 21, as well as the support and auxiliary rotation of the bearing seat 20, can drive the gear barrel 21 to rotate. At this time, the electric push rod 22 pushes the grinding sleeve 23 to contact the stator barrel 8, so that the grinding work on the outer surface of the stator barrel 8 can be completed, ensuring the smooth progress of the grinding work on the outer surface of the stator barrel 8.

[0029] Two hydraulic push rods 26 are fixedly connected to the inner wall of the sliding groove 18, and the telescopic end of each hydraulic push rod 26 is fixedly connected to the right side of the movable plate 19.

[0030] The outer surface of another limit sleeve 9 is fixedly connected to two connecting plates 11, and two hydraulic rods 12 are arranged above the base plate 1. The telescopic end of each hydraulic rod 12 is fixedly connected to the right side of the connecting plate 11, and the upper surface of the base plate 1 is fixedly connected to a limit plate 27. The right end of each hydraulic rod 12 is fixedly connected to the left side of the limit plate 27.

[0031] The working principle of the utility model is as follows: when in use, firstly connect the rotating motor 3, the hydraulic rod 12, the electric push rod 22, the rotating motor 24 and the hydraulic push rod 26 with the power supply, and then set the stator barrel 8 to be polished on the polishing frame 5, at this time, the polishing strip 7 can fit the tapered groove inside the stator barrel 8, and then use the support frame 10 to cooperate with one of the limiting sleeves 9 to limit the left position of the stator barrel 8, and then push the right limiting sleeve 9 to move left to limit the right position of the stator barrel 8 by the hydraulic rod 12, at this time, the power provided by the rotating motor 3 can cooperate with the support plate 2 to drive the reciprocating screw 4 to rotate, and use the two-way special thread on the reciprocating screw 4 and the limiting of the limiting column 17 to drive the polishing frame 5 to move back and forth left and right, and then drive the polishing strip 7 to polish the more complex tapered groove on the inner wall of the stator barrel 8, so that the motor stator processing grinder can grind the tapered groove on the inner wall of the motor stator, ensure the internal precision of the tapered groove of the motor stator, so that the subsequent winding work of the stator can be carried out smoothly, which greatly increases the motor stator The use effect of the stator processing grinder is that when it is necessary to grind the outer surface of the stator barrel 8, the pinion 25 is driven to rotate by the power provided by the rotating motor 24. The threaded connection relationship between the pinion 25 and the gear barrel 21, as well as the support and auxiliary rotation of the bearing seat 20, can drive the gear barrel 21 to rotate. At this time, the electric push rod 22 is cooperated to push the grinding sleeve 23 to contact the stator barrel 8, so that the grinding work on the outer surface of the stator barrel 8 can be completed. At the same time, the power provided by the hydraulic push rod 26 can be used to push the movable plate 19 to slide left and right inside the sliding groove 18, thereby driving the bearing seat 20 and the grinding sleeve 23 to move left and right, so that the outer surface of the stator barrel 8 can be more comprehensively polished. Finally, when it is necessary to grind stator barrels 8 of different specifications, it is only necessary to unscrew the positioning bolt 16, and through the clamping relationship between the clamping plate 6 and the grinding frame 5, the grinding strips 7 of corresponding specifications can be disassembled and installed according to the stator barrels 8 of different specifications, so that the motor stator processing grinder can adapt to the grinding work of the conical grooves on the inner wall of the stator barrels 8 of different specifications.
