[0043] Referring to Figures 1 to 19 The small motor is light in weight, and the device comprises a bottom plate 1, a supporting plate 2, a driving member 5 and a belt pulley collecting container, wherein:

[0044] The bottom plate 1 is arranged on a workbench, and the bottom plate 1 is a long strip-shaped plate, and the upper surface of the bottom plate 1 is a horizontal plane. Perforations 101 are formed in the bottom plate 1 and extend through the upper end and the lower end of the bottom plate 1 in the vertical direction.

[0045] The supporting plate 2 is arranged on the bottom plate 1 and is arranged vertically, and the supporting plate 2 is located close to the position of the perforations 101. A through hole 201 is formed in the supporting plate 2 and extends through the left side and the right side of the supporting plate 2. A limiting member 3 is arranged on one of the left side and the right side of the supporting plate 2. The limiting member 3 has a clamping groove, and the clamping groove extends through the upper end and the lower end of the limiting member 3. The clamping groove is located above the perforations 101 and is in communication with the perforations 101.

[0046] The driving member 5 comprises a driving body and a driving shaft. The driving body is arranged on the side of the supporting plate 2 away from the limiting member 3. For example, the limiting member 3 is arranged on the left side of the supporting plate, and the driving body is arranged on the right side of the supporting plate 2. The driving member 5 can be a pneumatic cylinder or a motor.

[0047] The belt pulley collecting container is located below the perforations 101 and is used for collecting the belt pulleys disassembled by the device. The upper side of the belt pulley collecting container is open, and the belt pulleys separated from the motor shaft fall into the belt pulley collecting container, so that the belt pulleys are conveniently collected without the need for manual arrangement, thereby reducing the workload.

[0048] The device has a working state. When in the working state, the small motor to be disassembled 10 is arranged on the side of the limiting piece 3 away from the support plate 2. For example, the small motor to be disassembled is arranged on the left side of the support plate 2, the driving piece is arranged on the right side of the support plate 2, the motor shaft of the small motor faces the support plate 2, the belt pulley 11 is clamped in the clamping groove, and one end of the driving shaft penetrates through the through hole 201 on the support plate 2 to push the motor shaft to move away from the support plate 2. Since the belt pulley is clamped in the clamping groove, the motor shaft moves away from the support plate 2 and the clamping groove, so that the belt pulley is separated from the motor shaft. After the belt pulley is separated, the belt pulley falls from the perforation 101 to the belt pulley collecting container due to the limitation of the clamping groove, and then the small motor is taken away. Then, other small motors to be disassembled are placed. After the belt pulley is quickly collected, the disassembly speed is fast, and the required manpower is small.

[0049] In some embodiments, the limiting piece 3 includes two first plates 301 and a second plate 302. The two first plates 301 are oppositely arranged, one end of each of the two first plates 301 is connected with the support plate 2, and the second plate 302 is connected with the other end of each of the two first plates 301 (a folding plate is arranged on one side of the first plate 301 and connected with the second plate 302). The second plate 302 is opposite to the support plate 2 and parallel to the support plate 2. The second plate 302, the first plate 301, and the support plate 2 form a clamping groove. The second plate 302 is provided with a slot 3021, which is recessed downward from the upper end of the second plate 302. The motor shaft of the small motor to be disassembled is clamped in the slot 3021.

[0050] In some embodiments, the device further includes a top rod 6 connected with one end of the driving shaft away from the driving body. The top rod 6 is used for pushing the motor shaft of the small motor to be disassembled.

[0051] In some embodiments, the top rod 6 includes a first segment 601, a second segment 602, and a third segment 603 connected in sequence. The outer diameter of the second segment 602 is greater than the outer diameters of the first segment 601 and the third segment 603. The outer diameter of the third segment 603 is smaller than the outer diameters of the first segment 601 and the second segment 602. The first segment 601 is threadedly connected with the driving shaft. The outer diameter of the second segment 602 is equal to the outer diameter of the driving shaft. The end face of the second segment 602 away from the third segment 603 abuts against the end face of the driving shaft, so as to prevent the top rod 6 from loosening and ensure stable and reliable connection. The third segment 603 is used for pushing the motor shaft of the small motor to be disassembled.

Alternatively, the mounting holes 202 are circular.

[0055] In this example, the fasteners 7 have opposite two ends, one end of the fastener 7 is threadedly connected with the driving body, and the other end of the fastener 7 extends out of the mounting hole 202 of the support plate 2 by a distance, and the other end of the fastener 7 extending out is provided with a nut which is locked on the support plate 2, so as to fixedly connect the fastener 7 with the support plate 2.

[0056] In some embodiments, the device further comprises a shield 8 which is arranged on the left side of the support plate 2, is connected with the bottom plate 1, and covers the fasteners 7. The shield 8 is arranged to prevent the driving member 5 from colliding with the support plate 2. Referring to Figure 19 , the shield 8 has a U-shaped space, and comprises a first support plate 801, two second support plates 802, and two third support plates 803. The two second support plates 802 are oppositely arranged, are connected with the opposite two ends of the same side of the first support plate 801, the two third support plates 803 are respectively connected with the sides of the two second support plates 802 away from each other, the third support plates 803 are parallel to the first support plate 801, and the first support plate 801 is connected with the bottom plate 1 through a bolt and nut assembly.

[0057] In this example, the device further comprises a backing plate 4 which is arranged on the bottom plate 1, is connected with the bottom plate 1, and is used to place the small motor to be disassembled. The backing plate 4 is arranged to improve the center height of the motor shaft of the small motor to be disassembled, so that the center line of the motor shaft coincides with or has a small difference from the center line of the driving shaft, and the driving shaft can push the motor shaft.

[0058] In some embodiments, a long strip-shaped opening 401 is formed on the backing plate 4, and the extending direction of the opening 401 is parallel to the extending direction of the driving shaft. The position of the backing plate 4 on the bottom plate 1 can be adjusted along the extending direction of the driving shaft, and the backing plate 4 is suitable for small motors with different center heights and end face structures. The backing plate 4 can be made of nylon material.

[0059] In the example, the device further comprises two baffles 9, which are oppositely arranged and respectively arranged on two sides of the limiting member 3, and the small motor to be disassembled is located between the two baffles 9, so as to limit the movement of the small motor to be disassembled in a direction parallel to the extension direction of the driving shaft during disassembly. Referring to Figure 18 , the baffle 9 comprises a first baffle part 91 and a second baffle part 92, the first baffle part 91 is connected with the second baffle part 92 and perpendicular to the second baffle part 92, the baffle 9 is L-shaped, the first baffle part 91 is horizontally arranged on the bottom plate 1, the first baffle part 91 is connected with the bottom plate 1 through a bolt-nut assembly, the second baffle part 92 is vertically arranged, the second baffle parts 92 of the two baffles 9 are oppositely arranged, and the first baffle part 91 of the two baffles 9 is farther away from the limiting member 3 than the second baffle part 92.
