DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-5 The utility model is further described as follows:

[0020] A motor stator insulation paper protection device, a guide disc 2 is arranged on a mounting bracket 1, a circular hole 5 is arranged in the middle of the guide disc 2, a plurality of guide grooves are evenly distributed on the guide disc 2 on the periphery of the circular hole 5, a protection strip 4 is slidably connected with the guide groove, so that the protection strip 4 can be telescopically arranged on the periphery of the circular hole 5, the top of the guide disc 2 is rotatably connected to a driving disc 3, a cover plate 18 is arranged on the top of the driving disc 3, an arc-shaped driving groove 6 is opened on the driving disc 3, a movable pin 7 can move along the arc-shaped driving groove 6, the bottom of the movable pin 7 is fixed on the protection strip 4, the side of the driving disc 3 is connected to a driving plate 8, a bearing 9 is arranged on the outside of the driving shaft, a strip hole is opened on the driving plate 8, the bearing 9 can move along the strip hole, the driving shaft is connected to a driving arm 10, the driving arm 10 is connected to a driving motor 11, and the driving motor 11 is fixed to the side of the guide disc 2 through a fixing frame 12. The driving motor 11 drives the driving arm 10 to rotate, and the driving arm 10 drives the bearing 9 on the driving shaft to move. The bearing 9 moves in the strip hole of the driving plate 8 and drives the driving plate 8 to rotate. The driving plate 8 drives the driving disc 3 to rotate relative to the guide disc 2. The arc-shaped driving groove 6 on the driving disc 3 drives the movable pin 7 therein to move. The movable pin 7 drives the protective strip 4 to slide along the guide groove. The movement of the protective strip 4 drives the working end of the end to extend and retract relative to the circular hole 5. When the insulating paper needs to be protected, the working end extends and retracts after the work is completed.

[0021] The side of the mounting bracket 1 is provided with a position adjustment block b15 fixed on the column, and the upper and lower ends of the position adjustment block b15 are respectively threadedly connected to the adjustment bolt b16 and the adjustment bolt c17. The mounting bracket 1 is connected to the column through the fixing bolts. A plurality of mounting holes are provided in the height direction of the column. The fixing bolts are assembled with the mounting holes at different heights to adjust the height position of the mounting bracket on the column, thereby adjusting the height difference between the working end of the protective strip 4 and the bottom insulating paper. The adjusted height difference can better protect the insulating paper.

The width of the guide grooves is smaller than the width of the top opening of the insulating paper. A positioning groove is provided on the side of the stator. Through the positioning of the positioning grooves, the slots of the stator are aligned with the guide grooves one by one up and down. The copper wire will enter the guide groove along the guide slope. Under the guiding action of the guide groove, the copper wire can enter the copper wire slot of the stator without contacting the top opening of the insulating paper, thereby avoiding damage to the insulating paper.
