[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1As shown, a motor shaft outer circle processing fixture includes a processing base plate 1, the left and right parts of the top of the processing base plate 1 are fixedly connected with a clamping mechanism 3, the top of the clamping mechanism 3 is movably connected with a motor shaft body 2, and the outer surface of the clamping mechanism 3 is fixedly connected with a stabilizing mechanism 4.

[0028] It should be noted that by rotating the rocker 22 set on both sides and cooperating with the two-way threaded rod 23, the two limit sliders 24 are moved toward the middle. At the same time, since the limit slider 24 is a T-shaped block, it not only prevents the clamping frame 26 from tipping over, but also allows the limit slider 24 to move more stably. In conjunction with the provided protective pad 27, the motor shaft body 2 can be well clamped and fixed without damaging the motor shaft body 2, thereby achieving a better clamping effect. By rotating the U-shaped rod 43 and cooperating with the spring 44 with elastic force, the U-shaped rod 43 can smoothly slide into the middle position of the two stabilizing plates 46. The provided stabilizing plate 46 can effectively prevent the U-shaped rod 43 from sliding, thereby stabilizing the two clamping frames 26, so that the clamping frames 26 will not move easily, which is more convenient for processing the motor shaft body 2.

[0029] like Figure 2 , Figure 3 As shown, the clamping mechanism 3 includes two brackets 21 and two rocking arms 22. The bottoms of the two brackets 21 are fixedly connected to the left and right parts of the top of the processing base plate 1. The rear ends of the two rocking arms 22 are rotatably connected to the left and right parts of the front end of the processing base plate 1. The rear ends of the two rocking arms 22 pass through the front end of the processing base plate 1 and are fixedly connected with a two-way threaded rod 23. Limiting grooves 25 are provided at the left and right positions of the processing base plate 1. The rear ends of the two-way threaded rods 23 are rotatably connected to the rear sides of the limiting grooves 25. Two limiting sliders 24 are threadedly connected to the front and rear positions of the outer surfaces of the two-way threaded rods 23. The tops of the two limiting sliders 24 are fixedly connected to two clamping frames 26.

[0030] It should be noted that, first, the motor shaft body 2 to be processed is placed on the two brackets 21. The upper part of the bracket 21 is arranged in an arc shape, which can well adapt to the cylindrical motor shaft body 2. Then, the position of the motor shaft body 2 is adjusted so that the left and right ends of the motor shaft body 2 are located in the middle of each of the two left and right clamping frames 26. By rotating the two rockers 22, the bidirectional threaded rod 23 is driven to rotate clockwise. The bidirectional threaded rod 23 is arranged with the middle as the boundary, and the threads extend to the front and rear ends, and the threads of the two parts are in opposite directions. Due to the bidirectional threaded rod 23 and the two limit The slider 24 is threadedly connected, so that the two limit sliders 24 move toward the middle. The limit slider 24 and the limit slide groove 25 are both T-shaped blocks, and the two are relatively fit, which prevents the clamping frame 26 from tipping over, so that the limit slider 24 can move more stably, and then drive the two clamping frames 26 to move toward the middle, so that the protective pads 27 on both sides contact the two ends of the motor shaft body 2. The protective pads 27 are arc-shaped and have a large arc, which can clamp and fix the motor shaft body 2 well without damaging the motor shaft body 2, thereby achieving a better clamping effect.

[0031] like Figure 2 As shown, a protective pad 27 is fixedly connected to the middle position of the opposite surfaces of the two clamping frames 26, and the protective pad 27 is in the shape of an arc plate.

[0032] It should be noted that the protection pads 27 on both sides contact the two ends of the motor shaft body 2. The protection pads 27 are arc-shaped with a large arc, which can clamp and fix the motor shaft body 2 well without damaging the motor shaft body 2.

[0033] like Figure 2 As shown, the tops of the two brackets 21 are both in the shape of arc plates, and the inner wall diameter of the brackets 21 is larger than the diameter of the outer surface of the front and rear parts of the motor shaft body 2 .

[0034] It should be noted that the upper portion of the bracket 21 is arc-shaped, which can well adapt to the cylindrical motor shaft body 2.

[0035] like Figure 2 , Figure 3 As shown, the two limiting sliding blocks 24 are both in the shape of a T-shaped block, and the limiting sliding groove 25 is in the shape of a T-shaped block.

[0036] It should be noted that the limiting slider 24 and the limiting slide groove 25 are both T-shaped blocks, and the two are relatively well matched, which prevents the clamping frame 26 from tipping over, so that the limiting slider 24 can move more stably.

[0037] like Figure 4 , Figure 5As shown, the stabilizing mechanism 4 includes two rotating blocks 41, the opposite surfaces of the two rotating blocks 41 are fixedly connected to the upper positions on the left and right sides of the rear clamping frame 26, the opposite surfaces of the two rotating blocks 41 are rotatably connected to two sliding sleeves 42, the lower ends of the two sliding sleeves 42 are movably connected to a U-shaped rod 43, the top ends of the left and right parts of the U-shaped rod 43 are fixedly connected to two circular plates 45, the tops of the two circular plates 45 are fixedly connected to two springs 44, and the tops of the two springs 44 are fixedly connected to the tops of the inner walls of the two sliding sleeves 42.

[0038] It should be noted that by rotating the U-shaped rod 43 forward, the sliding sleeve 42 rotates forward along the rotating block 41, and continues to rotate so that the U-shaped rod 43 is placed on the front clamping frame 26, and then the U-shaped rod 43 is pulled, thereby driving the U-shaped rod 43 to move forward, thereby stretching the spring 44. After the U-shaped rod 43 is stretched to exceed the length of the stabilizing plate 46, the U-shaped rod 43 is rotated again so that the U-shaped rod 43 is level with the ground, and then the U-shaped rod 43 is slowly released. Under the action of the spring 44, the U-shaped rod 43 slides into the middle position of the two stabilizing plates 46. The stabilizing plates 46 can effectively prevent the U-shaped rod 43 from sliding, thereby stabilizing the two clamping frames 26 so that the clamping frames 26 will not move easily.

[0039] like Figure 5 As shown, the outer diameters of the two springs 44 are smaller than the inner wall diameter of the sliding sleeve 42 , and the outer diameters of the two springs 44 are smaller than the outer surface diameter of the circular plate 45 .

[0040] It should be noted that the spring 44 is stretched smoothly, and under the elastic force of the spring 44 , the U-shaped rod 43 can slide into the middle position between the two stabilizing plates 46 .

[0041] like Figure 5 , Figure 6 As shown, two stabilizing plates 46 are fixedly connected to the upper positions of the front sides of the two front clamping frames 26 , the distance between the two stabilizing plates 46 is slightly larger than the outer ring diameter of the U-shaped rod 43 , and the width of the two stabilizing plates 46 is slightly larger than the outer ring diameter of the U-shaped rod 43 .

[0042] It should be noted that the stabilizing plate 46 can effectively prevent the U-shaped rod 43 from sliding down, thereby stabilizing the two clamping frames 26 so that the clamping frames 26 will not move easily.

[0043] The working principle of the utility model is as follows: first, the motor shaft body 2 to be processed is placed on the two brackets 21. The upper part of the bracket 21 is arc-shaped, which can well adapt to the cylindrical motor shaft body 2. Then, the position of the motor shaft body 2 is adjusted so that the left and right ends of the motor shaft body 2 are located in the middle position of each of the two left and right clamping frames 26. By rotating the two rockers 22, the two-way threaded rod 23 is driven to rotate clockwise. The two-way threaded rod 23 is divided by the middle, and the threads extend to the front and rear ends, and the threads of the two parts are in opposite directions. Since the two-way threaded rod 23 is threadedly connected with the two limit sliders 24, the two limit sliders 24 are moved toward the middle. The limit slider 24 and the limit slide groove 25 are both T-shaped blocks, and the two are more compatible, which prevents the clamping frame 26 from tipping over, so that the limit slider 24 can move more stably, thereby driving the two clamping frames 26 to move toward the middle, so that the protective pads on both sides The U-shaped rod 43 is then pulled back to move the U-shaped rod 43 forward, and the U-shaped rod 43 is then pulled back to move the U-shaped rod 43 forward, thereby causing the spring 44 to stretch. After the U-shaped rod 43 is stretched beyond the length of the stabilizing plate 46, the U-shaped rod 43 is rotated again to make the U-shaped rod 43 level with the ground, and then the U-shaped rod 43 is slowly released. Under the action of the spring 44, the U-shaped rod 43 slides into the middle position of the two stabilizing plates 46. The stabilizing plates 46 can effectively prevent the U-shaped rod 43 from sliding off, thereby stabilizing the two clamping frames 26, so that the clamping frames 26 will not move easily.
