[0034] As shown in Figure 2 , Figure 3 and Figure 4 , the conversion test mechanism 7 includes a one-way gear 71, a sliding sleeve pipe 72, a first sliding piece 73, a first rack 74 and a first spring 75, the connecting frame 1 lower portion intermediate is welded with the sliding sleeve pipe 72, the sliding sleeve pipe 72 is slidably connected with the first sliding piece 73, the first sliding piece 73 right end and the moving frame 601 are connected, the moving frame 601 can drive the first sliding piece 73 to move, the first sliding piece 73 left side is welded with the first rack 74, the first sliding piece 73 can drive the first rack 74 to move, the frame connecting rod 3 lower portion is keyed with the one-way gear 71, the first rack 74 and the one-way gear 71 are engaged, the one-way gear 71 is located below the connecting disc 4, the first sliding piece 73 left side and the sliding sleeve pipe 72 left side between being connected with the first spring 75, the first spring 75 can drive the first sliding piece 73 to move reset.

[0035] As shown in Figure 2 , Figure 5 and Figure 6As shown, the central stabilizing mechanism 8 includes a threaded sleeve 81, a rotating ring 82, a fixed part 83, a clamping part 84, a second spring 85, a guide 86, a nut plate 87, a pull rope 88 and a nut connecting frame 89. The rotating ring 82 is rotatably connected to the lower part of the frame connecting rod 3 and is located above the connecting disc 4. The threaded sleeve 81 is welded to the top of the rotating ring 82 and is rotatably connected to the middle part of the frame connecting rod 3. The rotating ring 82 rotates to drive the threaded sleeve 81 to rotate. The nut connecting frame 89 is connected to the upper part of the frame connecting rod 3 and is rotatably connected to the upper part of the threaded sleeve 81. The nut plate 87 is slidably connected to the nut connecting frame 89 and is threadedly connected to the threaded sleeve 81. The threaded sleeve 81 rotates to drive the nut plate 87 to move up and down. The connecting barrel 2 has three fixed parts 83 evenly welded to the inner top wall in the circumferential direction. Each fixed part 83 has a clamping part 84 slidably connected thereto. The clamping part 84 is slidably connected to the connecting barrel 2. When the clamping part 84 moves outward, it clamps the micro motor commutator sheet. Each clamping part 84 and the fixed part 83 are provided with a second spring 85, which can drive the clamping part 84 to move back to the original position. Each clamping part 84 is provided with a pull rope 88, and the lower end of the pull rope 88 is connected to the top of the nut plate 87. The connecting barrel 2 has three guides 86 evenly welded to the inner top wall in the circumferential direction. The fixed part 83 is located between the guides 86, and the pull rope 88 passes through the guides 86.

[0036] Before voltage detection of the commutator segment of the micro motor, the commutator segment can be sleeved on the upper part of the frame connecting rod 3, so that the commutator segment of the micro motor is sleeved outside the clamping piece 84. Then the threaded sleeve 81 can be driven to rotate by rotating the rotating ring 82, and the threaded sleeve 81 drives the nut plate 87 to move downward. When the nut plate 87 moves downward, it will drive the clamping piece 84 to move outward through the pull rope 88, and the second spring 85 is compressed. In this way, the clamping piece 84 can clamp the commutator segment of the micro motor, and at the same time, the commutator segment of the micro motor can be centered, thereby improving the stability of the commutator segment of the micro motor. Then the extension movement of the extension rod of the air cylinder 5 can drive the moving frame 601 and the voltage tester 6 to move leftward, and the first rack 74 is driven to move leftward by the moving frame 601, and the first spring 75 is stretched. The leftward movement of the first rack 74 drives the one-way gear 71 to rotate, and the rotation of the one-way gear 71 drives the frame connecting rod 3 to rotate, and the rotation of the frame connecting rod 3 drives the connecting barrel 2 and the connecting disc 4 to rotate. The connecting barrel 2 also drives the clamping piece 84 to rotate, and the clamping piece 84 drives the commutator segment of the micro motor to rotate. When the extension rod of the air cylinder 5 stops extending, the first rack 74 stops moving, and the voltage tester 6 is turned on. The voltage tester 6 can detect the voltage of the commutator segment of the micro motor. After the detection is completed, the extension rod of the air cylinder 5 can be controlled to shorten, which drives the moving frame 601, the first sliding piece 73 and the voltage tester 6 to move rightward, and under the action of the first spring 75, the first sliding piece 73 and the first rack 74 move rightward to reset. At this time, the first rack 74 drives the one-way gear 71 to idle, and the frame connecting rod 3 does not rotate. Repeating the above operation can realize intermittent commutation of the commutator segment of the micro motor, and after commutation, the voltage of the commutator segment of the micro motor can be detected automatically. After the detection of the commutator segment of the micro motor is completed, the voltage tester 6 is turned off. When the commutator segment of the micro motor needs to be removed, the rotating ring 82 can be rotated in the opposite direction, the threaded sleeve 81 is driven to rotate in the opposite direction, the threaded sleeve 81 drives the nut plate 87 to move upward, and the nut plate 87 releases the pull rope 88. Under the action of the second spring 85, the clamping piece 84 moves rightward to reset, so that the commutator segment of the micro motor is released, and the commutator segment of the micro motor can be removed.

[0037] Example 2

[0038] On the basis of example 1, as Figure 2 , Figure 7 , Figure 8 and Figure 9As shown, it also includes an automatic expansion mechanism 9, which includes a fixed plate 91, bevel gear 92, spur gear 93, first connecting rod 94, second rack 95, third spring 96, second threaded rod 97 and nut handle 98, the top left side of the connecting disc 4 is welded with the fixed plate 91, the upper part of the fixed plate 91 is connected with the spur gear 93 through the rotating shaft, the upper part of the fixed plate 91 is connected with the bevel gear 92 through the rotating shaft, the bevel gear 92 is located on the right side of the spur gear 93, the lower part of the rotating ring 82 is also welded with the bevel gear 92, the two bevel gears 92 are engaged, the rotation of the bevel gear 92 will drive the rotating ring 82 to rotate, the top left rear side of the connecting disc 4 and the inner top wall of the connecting barrel 2 are welded with the first connecting rod 94, the first connecting rod 94 is slidably connected with the second rack 95, the second rack 95 slides up and down on the first connecting rod 94, the second rack 95 and the spur gear 93 are engaged, the top of the second rack 95 and the inner top wall of the connecting barrel 2 are connected with the third spring 96, the third spring 96 can drive the second rack 95 to move back to the original position, the left rear side of the connecting barrel 2 is slidably connected with the second threaded rod 97, the second threaded rod 97 is threadedly connected with the nut handle 98, the top of the nut handle 98 is rotatably connected with the lower part of the second rack 95, when the nut handle 98 rotates, it will drive the second rack 95 to move.

[0039] Firstly, the size of the commutator segment of the micro motor can be used to adjust the distance of the clamping member 84 moving outward, so as to adapt to different sizes of the commutator segment of the micro motor. To adjust the distance of the clamping member 84 moving outward, the position of the second rack 95 on the first connecting rod 94 needs to be adjusted. Initially, the third spring 96 is in a stretched state. The second rack 95 can be pushed upward by rotating the nut handle 98. When the nut handle 98 moves upward, the third spring 96 is slowly compressed and reset. When the nut handle 98 is reversed, the second rack 95 moves downward, and the third spring 96 is stretched. When the second rack 95 moves upward, the fewer the teeth of the second rack 95 engaging with the spur gear 93, the smaller the angle of the second rack 95 driving the spur gear 93 to rotate, and the shorter the distance of the clamping member 84 moving outward. Therefore, the smaller the size of the clamping commutator segment of the micro motor. Conversely, when the second rack 95 moves downward, the more the teeth of the second rack 95 engaging with the spur gear 93, the greater the angle of the second rack 95 driving the spur gear 93 to rotate, and the longer the distance of the clamping member 84 moving outward. Therefore, the larger the size of the clamping commutator segment of the micro motor. After adjusting the position of the nut handle 98 and the second rack 95, the commutator segment of the micro motor is placed. During the process of placing the commutator segment of the micro motor, the commutator segment of the micro motor moves the second threaded rod 97 downward. The second threaded rod 97 moving downward drives the nut handle 98 to move downward, and the third spring 96 is stretched. The nut handle 98 drives the second rack 95 to move downward, and the second rack 95 moving downward drives the spur gear 93 to rotate. The rotation of the spur gear 93 drives the bevel gear 92 to rotate through the rotating shaft. The rotation of the bevel gear 92 drives the rotating ring 82 to rotate, and the rotation of the rotating ring 82 drives the threaded sleeve 81 to rotate. In turn, the clamping member 84 moves outward to clamp the commutator segment of the micro motor. In this way, the size of the commutator segment of the micro motor can be used to adjust the distance of the clamping member 84 moving outward, so as to automatically clamp the commutator segment of the micro motor and automatically center the commutator segment of the micro motor. If it is necessary to take out the commutator segment of the micro motor, a tool can be used to move the commutator segment of the micro motor upward. Then, the commutator segment of the micro motor is separated from the second threaded rod 97. Under the action of the third spring 96, the second rack 95 moves upward, driving the nut handle 98 to move upward. The nut handle 98 drives the second threaded rod 97 to move upward. The upward movement of the second rack 95 drives the spur gear 93, the rotating shaft and the bevel gear 92 to reverse, and in turn, the clamping member 84 moves inward to completely release the commutator segment of the micro motor.

[0040] As Figure 2 , Figure 11 and Figure 10As shown, the top stabilizing mechanism 10 comprises a fixing frame 101, a pressing piece 102, a fourth spring 103, a first threaded rod 104, a nut ring 106, a second connecting rod 107, a sliding sleeve 108, a clamping piece 109 and a fifth spring 1010. The fixing frame 101 is welded to the lower right side of the connecting frame 1 and is located to the right of the connecting barrel 2. The pressing piece 102 is slidably connected to the fixing frame 101 and can move up and down on the fixing frame 101. The pressing piece 102 can limit the top of the micro motor commutator segment and improve the stability of the micro motor commutator segment. The fourth spring 103 is connected between the bottom of the pressing piece 102 and the fixing frame 101. The second connecting rod 107 is welded to the lower right rear side of the connecting frame 1. The first threaded rod 104 is rotatably connected to the lower right front side of the connecting frame 1. The second connecting rod 107 and the first threaded rod 104 are located to the right of the fixing frame 101. The sliding sleeve 108 is slidably connected to the second connecting rod 107. The nut ring 106 is threadedly connected to the upper part of the first threaded rod 104. The rotation of the first threaded rod 104 can drive the nut ring 106 to move up and down. The clamping piece 109 is slidably connected between the nut ring 106 and the sliding sleeve 108. The upper left part of the clamping piece 109 is an inclined surface. The bottom of the clamping piece 109 can clamp the position of the pressing piece 102. The fifth spring 1010 is connected between the right side of the sliding sleeve 108 and the clamping piece 109. The fifth spring 1010 is also connected between the right side of the nut ring 106 and the clamping piece 109.

[0041] As shown in Figure 2 , Figure 9 and Figure 10 , the rotating handle 105 is connected to the middle part of the first threaded rod 104. The rotation of the rotating handle 105 can drive the first threaded rod 104 to rotate.

[0042] Initially, the bottom of the clamping part 109 is in the state of clamping the position of the pressing part 102, and the fourth spring 103 is in the compressed state; before placing the micro motor commutator sheet, the clamping part 109 can be pulled to the right, the fifth spring 1010 is stretched, the clamping part 109 moves to the right and separates from the pressing part 102, then the pressing part 102 moves upward under the action of the fourth spring 103, and releases the clamping part 109, under the action of the fifth spring 1010, the clamping part 109 moves to the left and resets, then the micro motor commutator sheet is placed, and the position of the pressing part 102 is adjusted according to the height of the micro motor commutator sheet, the first threaded rod 104 can be driven to rotate forward and reverse by rotating the handle 105 forward and reverse, the first threaded rod 104 can drive the nut ring 106 to move up and down, the nut ring 106 drives the clamping part 109, the fifth spring 1010 and the sliding sleeve 108 to move up and down, so that the position of the clamping part 109 is adjusted, and the position of the pressing part 102 is adjusted; then the pressing part 102 is moved downward, the fourth spring 103 is compressed, and when the lower part of the pressing part 102 contacts the left part of the clamping part 109, the pressing part 102 will push the clamping part 109 to the right because of the contact between the inclined surface of the upper left part of the clamping part 109 and the pressing part 102, so the fifth spring 1010 is compressed, and when the lower part of the pressing part 102 moves to the bottom of the clamping part 109, the clamping part 109 moves to the left and clamps the pressing part 102 under the action of the fifth spring 1010, so that the pressing part 102 can limit the top of the micro motor commutator sheet, so that the pressing part 102 can limit the top of the micro motor commutator sheet when the micro motor commutator sheet rotates, so as to improve the stability of the micro motor commutator sheet.
