On the top of the placement rack 21, multiple rubber pads 22 are fixedly connected. On the top of the fixed table 1, multiple limiting grooves 5 are opened;

[0033] Specifically, multiple rubber pads 22 are fixedly installed on the top of the placement rack 21. The top of the rubber pad 22 is designed with an arc-shaped groove, which can be suitable for placing motors of different shapes and ensure the stability of the motor housing; then, according to the actual shape of the motor housing, the arc-shaped clamping plate 7 and the square clamping plate 8 are adjusted. The arc-shaped clamping plate 7 and the square clamping plate 8 are integrally designed. A clamping groove 9 is opened between the arc-shaped clamping plate 7 and the square clamping plate 8. When the adjusted arc-shaped clamping plate 7 and the square clamping plate 8 are kept balanced, the adjusting bolt 11 on the connecting shell 10 is rotated inward, so that the spherical ball 12 at the end of the adjusting bolt 11 is inserted between the semi-circular plates 14. Under the extrusion of the spherical ball 12, the two sliding rods 13 expand to both sides, and the ends of the sliding rods 13 are inserted into the clamping groove 9 to complete the fixing process of the arc-shaped clamping plate 7 and the square clamping plate 8; by rotating the turntable 17, the bidirectional screw 4 drives the moving seat 23 on the outer wall to slide inward through the limiting groove 5, and the motor housing is clamped and fixed by the arc-shaped clamping plate 7 and the square clamping plate 8, improving the practicability and convenience of the fixture.

[0034] Refer to Figure 1 , Figure 2 and Figure 5, the adjusting mechanism 2 includes a rotating shaft 201. The outer wall of the rotating shaft 201 is rotatably connected to the front side of the fixed platform 1. The outer wall of the rotating shaft 201 is rotatably connected with a base 202. A sliding groove 206 is formed on the right side of the base 202. A first connecting member 205 is slidably connected inside the sliding groove 206. A fixed block 203 is fixedly connected to the right side of the base 202. Telescopic rods 204 are fixedly connected to both the left and right sides of the fixed block 203.

An inclined push plate 210 is slidably connected to the front side of each of the two second connecting members 209. The rear side of the fixed platform 1 is processed into an inclined surface, and the front side of the inclined push plate 210 is slidably connected to the rear side of the fixed platform 1;

[0035] Specifically, the fixed platform 1 and the base 202 are rotationally installed through the rotating shaft 201. At the same time, the rear side of the fixed platform 1 is processed into an inclined angle, and the inclined angle fits the outer wall of the inclined push plate 210; by starting the telescopic rod 204 to contract inward, the first connecting member 205 at the end of the telescopic rod 204 slides inward along the sliding groove 206. The model of the telescopic rod 204 is JC35W8; at the same time, a second connecting member 209 is slidably installed on the rear side of the inclined push plate 210. The first connecting member 205 and the second connecting member 209 are rotationally installed through the rotating plate 207. The rotating plates 207 cross each other and are fixed through the connecting shaft 208. At this time, when the first connecting member 205 slides inward, it drives the second connecting member 209 to slide synchronously, so that the rotating plates 207 gradually overlap and merge with each other; during the mutual rotation of the rotating plates 207, the inclined push plate 210 is pushed to slide forward, thereby driving the rear side of the fixed platform 1 to be lifted upward through the inclined push plate 210.

[0036] Refer to Figure 1 、 Figure 2 and Figure 5 , mounting plates 24 are arranged around the fixed platform 1. The adjacent sides of the mounting plates 24 are fixedly connected to the outer periphery of the base 202. Screw holes 25 are formed at the tops of the multiple mounting plates 24. Bolts 15 are threadedly connected inside the multiple screw holes 25;

[0037] Specifically, mounting plates 24 are fixedly installed around the outer wall of the base 202. Screw holes 25 corresponding to the diameter of the bolts 15 are formed at the tops of the mounting plates 24. Through the mutual connection of the bolts 15 and the screw holes 25, the entire positioning device is fixed to improve the stability of the device.

[0038] Working principle: First, when fixing the motor housing, place it on the tabletop of the placement rack 21. The multiple rubber pads 22 on the top of the placement rack 21 are suitable for placing motors of different shapes. Then, according to the actual shape of the motor housing, rotate and adjust the arc-shaped clamping plate 7 and the square clamping plate 8. When the adjusted arc-shaped clamping plate 7 and square clamping plate 8 are kept in balance, rotate the adjusting bolt 11 on the connecting shell 10 inward, so that the spherical ball 12 at the end of the adjusting bolt 11 is inserted between the semi-circular plates 14. Under the extrusion of the spherical ball 12, the sliding rods 13 on both sides expand to both sides, and the ends of the sliding rods 13 are inserted into the clamping grooves 9 to complete the fixing process of the arc-shaped clamping plate 7 and the square clamping plate 8; Rotate the turntable 17 to drive the moving seat 23 on the outer wall of the bidirectional screw rod 4 to slide inward, and clamp and fix the motor housing through the arc-shaped clamping plate 7 and the square clamping plate 8. At the same time, the rubber strips 20 and the anti-wear pads 19 on the arc-shaped clamping plate 7 and the square clamping plate 8 can greatly reduce the wear of the motor housing during clamping;

[0039] And when the motor housing is fixed, start the telescopic rod 204 to contract inward, so that the connecting piece one 205 at the end of the telescopic rod 204 slides inward along the chute 206. Through the inward sliding of the connecting piece one 205, drive the connecting piece two 209 to slide synchronously, so that the rotating plates 207 gradually overlap and merge with each other; During the mutual rotation of the rotating plates 207, push the inclined push plate 210 to slide forward. Through the inclined push plate 210 inserted into the inclined surface at the rear side of the fixed table 1, the rear side of the fixed table 1 is driven to lift upward, realizing the angle adjustment of the motor housing on the fixed table 1.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
