[0029] like Figure 5-6 As shown, this example can be used to test whether the motor shaft is eccentric when rotating.

[0030] Since the motor sensor includes a ring 101, a plurality of arc pieces 103 are arranged in a ring shape on the inner side of the ring 101, and square columns 104 are welded on the outer sides of the plurality of arc pieces 103. The plurality of square columns 104 are radially slidably connected to the ring 101, and a stop pin 107 is inserted in the middle of the square column 104, and the stop pin 107 is located on the outer side of the ring 101. A compression spring is sleeved on the square column 104, and the compression spring is located between the ring 101 and the arc piece 103. The compression spring gives the arc piece 103 and the square column 104 a force to slide outward, so that the arc piece 103 and the square column 104 always have a tendency to slide outward. The motor shaft 402 on the motor 401 needs to be inserted between the plurality of arc pieces 103. If the motor shaft 402 is eccentric when rotating, the motor shaft 402 will touch the arc piece 103, and then drive the arc piece 103 and the square column 104 to slide outward, thereby testing whether the motor shaft 402 is eccentric when rotating.

[0031] like Figure 5-6 As shown, this example can achieve the effect of judging the degree of eccentricity of the motor shaft 402 when it rotates by using the pressure value received by the pressure sensor 106.

[0032] Two connecting pieces 108 are welded to the outer side of the sleeve 101, and the outer ring 102 is welded to the two connecting pieces 108. The outer ring 102 is coaxially arranged with the sleeve 101, and the inner circumference of the outer ring 102 is annularly bonded with multiple pressure sensors 106. The multiple pressure sensors 106 are respectively located at the outer ends of multiple square columns 104, and multiple rubber rings 105 are bonded between the corresponding square columns 104 and the pressure sensors 106. When the arc piece 103 and the square column 104 slide outward, the square column 104 slides outward and presses the corresponding rubber ring 105. The rubber ring 105 applies force to the pressure sensor 106, and then the eccentricity of the motor shaft 402 during rotation is judged by the pressure value of the pressure sensor 106.

[0033] like Figure 9-10 As shown, this example can achieve the effect of conveniently fixing the sleeve ring 101 and the outer ring 102 on the outside of the motor shaft 402 .

[0034] Since a motor shaft 402 is provided on the motor 401, the motor shaft 402 is located on the inner side of the multiple arc pieces 103, and the two connecting members 108 are respectively fixed on the left ends of the two cross bars 309, and the right ends of the two cross bars 309 are fixed with a ring sleeve 301, which is sleeved on the outer shell of the motor 401. The ring sleeve 301 is threadedly connected with a fastening screw, and the two cross bars 309 are conveniently fixed to the outer shell of the motor 401 through the ring sleeve 301, and then the sleeve 101 and the outer ring 102 are conveniently fixed to the outside of the motor shaft 402.

[0035] like Figure 9-10 As shown, this example can achieve the effect of conveniently testing whether the housing of the motor 401 vibrates when it is running.

[0036] Since a ring seat 303 is welded on the ring sleeve 301, a rotating seat 304 is rotatably connected to the ring seat 303, a vertical column 306 is fixed on the upper side of the rotating seat 304, a sliding sleeve 307 is sleeved on the vertical column 306, a fastening screw is threadedly connected to the sliding sleeve 307, the fastening screw is pressed on the vertical column 306, an elastic rod 305 is welded on the right side of the sliding sleeve 307, L-shaped pieces 302 are fixed on both sides of the ring seat 303 on the ring sleeve 301, a convex rod 308 is fixed on the left side of the rotating seat 304, compression springs are fixed on both sides of the convex rod 308, and the outer ends of the two compression springs are respectively fixed on On the two L-shaped parts 302, when the shell of the motor 401 vibrates up and down, the elastic rod 305 will vibrate up and down elastically. When the shell of the motor 401 vibrates back and forth, it will drive the swivel seat 304 to rotate on the ring seat 303. At this time, the protruding rod 308 rotates with the swivel seat 304. The compression springs on the two L-shaped parts 302 can help the protruding rod 308 and the swivel seat 304 to return to their original positions. Then, when the shell of the motor 401 vibrates back and forth, the elastic rod 305 and the vertical column 306 rotate back and forth with the swivel seat 304 and then return to their original positions, which makes it convenient to test whether the shell of the motor 401 vibrates when it is running.

[0037] like Figure 7-10 As shown, this example can achieve the effect of testing whether the housing of the motor 401 vibrates up and down.

[0038] Since a convex seat 310 is welded on the rear side of the ring sleeve 301, a T-shaped frame 201 is slidably connected to the convex seat 310 in a transverse direction, a fastening screw is threadedly connected to the convex seat 310, and the fastening screw is pressed on the T-shaped frame 201, a round rod 202 is fixed on the T-shaped frame 201, a door-shaped piece 207 is fixed on the round rod 202, and pressure sensors 3 206 are bonded to the upper and lower sides of the inner side of the door-shaped piece 207. The two pressure sensors 3 206 are respectively located on both sides of the elastic rod 305. When the elastic rod 305 elastically vibrates up and down, it touches the two pressure sensors. The T-shaped frame 201 can slide left and right on the convex seat 310, thereby driving the round rod 202 and the door-shaped piece 207 to move left and right. The elastic rod 305 vibrates more and more towards the right end, and the door-shaped piece 207 is moved to different positions on the elastic rod 305, so as to conveniently set the amplitude of the vibration of the motor 401 to make the elastic rod 305 touch the pressure sensor 3 206. When the pressure sensor 3 206 is touched, it means that the motor 401 is operating abnormally.

[0039] like Figure 7-10 As shown, this example can achieve the effect that when the pressure sensor 204 is touched, it represents that the motor 401 is operating abnormally.

[0040] Since a bar 203 is welded on the T-shaped frame 201, a door-shaped piece 205 is fixed on the bar 203, and pressure sensors 204 are bonded to the front and rear sides of the inner side of the door-shaped piece 205. The two pressure sensors 204 are respectively located on the front and rear sides of the elastic rod 305. When the housing of the motor 401 vibrates back and forth, the elastic rod 305 swings back and forth and touches the pressure sensor 204. The door-shaped piece 205 is moved to different positions on the elastic rod 305, so that it is convenient to set the amplitude of the vibration of the motor 401 before the elastic rod 305 touches the pressure sensor 204. When the pressure sensor 204 is touched, it means that the motor 401 is operating abnormally.

[0041] like Figure 11-12 As shown, this example can achieve the effect of coaxially arranging the collar 101 and the outer ring 102, making it convenient to install parts toward the collar 101 and the outer ring 102.

[0042] Since the motor sensor processing equipment includes a cross 501, a cushion block 502, an arc edge 1 503 and an arc edge 2 504, the four ends of the cross 501 are fixed with cushion blocks 502, each cushion block 502 is fixed with an arc edge 2 504, and the four ends of the middle part of the cross 501 are fixed with an arc edge 1 503, the ring 101 is inserted between the four arc edges 1 503, and the outer ring 102 is inserted between the four arc edges 2 504. The cross 501, the four arc edges 1 503 and the four arc edges 2 504 can make the ring 101 and the outer ring 102 coaxially arranged, so as to facilitate the installation of parts toward the ring 101 and the outer ring 102; because the ring 101 and the outer ring 102 are not wide, the outer ring 102 is padded by the cushion block 502, so that the outer ring 102 is located in the middle position of the ring 101.

[0043] A motor sensor processing method comprises the following steps:

[0044] S1: insert the collar 101 between the four arc edges 1 503, and insert the outer ring 102 between the four arc edges 2 504, so that the collar 101 and the outer ring 102 are placed coaxially;

[0045] S2: Arrange a plurality of arc pieces 103 on the inner side of the collar 101, slide and insert a plurality of square columns 104 on the collar 101, and arrange a spring between the collar 101 and the arc pieces 103;

[0046] S3: Install the stop pin 107 on the square column 104 to prevent the square column 104 from being separated from the collar 101;

[0047] S4: The outer ring 102 is fixed to the outside of the sleeve ring 101 through two connecting pieces 108, and the multiple pressure sensors 106 are fixed to the inner periphery of the outer ring 102, so that the multiple pressure sensors 106 are respectively located at the outer ends of the multiple square columns 104.
