Description

Technical Field

[0001] The utility model relates to the technical field of motor control, in particular to a disassembly device for an encoder installed on a motor. Background Art

[0002] In order to facilitate automatic control, the motor is usually installed with an encoder. At present, the encoder is usually installed on the dummy shaft at the rear end of the motor shaft, using a keyless expansion installation method. The encoder plastic hollow shaft and the dummy shaft are interference fit, and the interference fit ensures that the encoder plastic hollow shaft and the motor shaft rotate synchronously. After a period of use, the encoder needs to be removed from the motor for maintenance or replacement. At present, tools such as open-end wrenches and plum wrenches are often used to disassemble the encoder. The encoder disassembly is labor-intensive and inefficient, which is not conducive to large-scale use. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a disassembly device for an encoder installed on a motor, which has low labor intensity and high disassembly efficiency.

[0004] The utility model solves the technical problem by adopting a technical solution: an encoder disassembly device installed on a motor comprises a main board, a rotating screw, a clamp and a handle, wherein the clamp comprises two clamping plates, the two clamping plates are arranged opposite to each other, and a clamping cavity is formed between the two clamping plates;

[0005] A threaded through hole is provided in the middle of the main board, and left and right side parts of the main board are respectively provided with left and right bar-shaped through holes, a rotating screw matches and passes through the threaded through hole and is connected by threads, and a handle is vertically connected to the upper end of the rotating screw;

[0006] The clamping plate is provided with connecting through holes, and the connecting bolts pass through the corresponding connecting through holes and the strip through holes in the left and right directions to detachably connect the clamping plate to the bottom of the main board.

[0007] Furthermore, the upper ends of the vertical connecting plates are connected, and the horizontal clamping plate is connected to the lower ends of the vertical connecting plates;

[0008] The connecting through holes are arranged in the transverse connecting plate body.

[0009] Furthermore, the inner surface of the transverse clamping plate body is inclined, and the end connected to the lower end of the vertical connecting plate body is the inclined upper end of the transverse clamping plate body.

[0010] Furthermore, an anti-slip protection pad is provided on the inner surface of the transverse clamping plate body.

[0011] Furthermore, the rotating screw includes a threaded portion and a square portion, the square portion is connected and arranged above the threaded portion, and the square portion is detachably connected to the handle.

[0012] Furthermore, it also includes a reinforcing nut, which is arranged on the main board and located above the threaded through hole, and the rotating screw rod is matched and passes through the reinforcing nut.

[0013] Furthermore, it also includes a guide sleeve, which is vertically connected and arranged below the main board, and the rotating screw passes through the guide sleeve.

[0014] Furthermore, the lower end of the rotating screw is in an arc shape.

[0015] The beneficial effects of the utility model are as follows: when disassembling the encoder, firstly, according to the cross-sectional size of the encoder, the width of the clamping cavity is adjusted by connecting bolts, left and right bar-shaped through holes and clamping plates, so that the width of the clamping cavity is slightly larger than the cross-sectional size of the encoder; then the clamp is mounted on the encoder and the encoder is clamped; finally, the disassembly personnel rotate the rotating screw by the handle, so that the rotating screw is against the false shaft of the motor shaft, and then continue to rotate the rotating screw until the encoder is loosened from the false shaft of the motor shaft. It can be seen that the encoder disassembly device of the utility model has a simple structure and is easy to use. It can significantly improve the disassembly efficiency of the encoder, effectively reduce the labor intensity, and reduce the possibility of damage to the encoder. In addition, the width of the clamping cavity of the encoder disassembly device of the utility model can be adjusted, which is suitable for the disassembly of encoders of different sizes and is conducive to large-scale use. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural schematic diagram of the utility model;

[0017] Marked as: main board 1, left and right bar-shaped through holes 11, rotating screw 2, clamping plate 3, horizontal connecting plate body 31, vertical connecting plate body 32, horizontal clamping plate body 33, anti-slip protection pad 34, clamping cavity 4, connecting bolt 5, handle 6, reinforcing nut 7, guide sleeve 8. DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The directions mentioned below are Figure 1 The position of each component in the figure is taken as the reference.

[0020] like Figure 1 As shown, the encoder disassembly device installed on the motor of the utility model comprises a main board 1, a rotating screw 2, a clamp and a handle 6, wherein the clamp comprises two clamping plates 3, the two clamping plates 3 are arranged facing each other, and a clamping cavity 4 is formed between the two clamping plates 3;

[0021] A threaded through hole is provided in the middle of the main board 1, and left and right side portions of the main board 1 are respectively provided with left and right bar-shaped through holes 11, the rotating screw 2 matches and passes through the threaded through hole and is connected by threads, and the handle 6 is vertically connected to the upper end of the rotating screw 2;

[0022] The splint 3 is provided with connecting through holes, and the connecting bolts 5 pass through the corresponding connecting through holes and the left and right strip through holes 11 to detachably connect the splint 3 to the bottom of the main board 1, so that one splint 3 is located on the left side of the rotating screw 2 and the other splint 3 is located on the right side of the rotating screw 2.

[0023] Since the main board 1 is provided with left and right strip through holes 11, the different fixing positions of the connecting bolts 5 and the left and right strip through holes 11 can realize the left and right position movement of the clamping plate 3 and the adjustment of the clamping cavity width, so that the encoder disassembly device of the utility model can be suitable for the disassembly of encoders of different sizes.

[0024] Specifically, the function of the clamping plate 3 is to be mounted on the encoder and clamp the encoder. In order to ensure its use effect, the preferred structure of the clamping plate 3 of the utility model is: Figure 1 As shown, the clamping plate 3 includes a transverse connecting plate body 31, a vertical connecting plate body 32 and a transverse clamping plate body 33. The transverse connecting plate body 31 is connected to the upper end of the vertical connecting plate body 32, and the transverse clamping plate body 33 is connected to the lower end of the vertical connecting plate body 32. The connecting through hole is set in the transverse connecting plate body 31. The area surrounded by the transverse connecting plate body 31, the vertical connecting plate body 32 and the transverse clamping plate body 33 in the two clamping plates 3 is the clamping cavity.

[0025] When the encoder is disassembled, the transverse card plate 33 needs to be inserted between the encoder and the motor to hook the encoder. To facilitate the use of the transverse card plate 33, the inner surface of the transverse card plate 33 is inclined, and the end connected to the lower end of the vertical connecting plate 32 is the inclined upper end of the transverse card plate 33. Since the inner surface of the transverse card plate 33 needs to contact the encoder during disassembly, in order to reduce the damage caused by the inner surface of the transverse card plate 33 to the encoder, the inner surface of the transverse card plate 33 is provided with an anti-skid protection pad 34, which is usually made of rubber.

[0026] Encoder disassembly is often performed online. Some motors are located in a narrow position, which makes it inconvenient to rotate the rotating screw 2 through the handle 6. Figure 1 As shown, the rotary screw 2 of the utility model includes a threaded portion and a square portion, the square portion is connected and arranged above the threaded portion, and the square portion is detachably connected to the handle 6. For the encoder disassembly in a relatively narrow motor position, the handle 6 is first removed, and then the rotary screw 2 is rotated by acting on the square portion with a tool such as a wrench.

[0027] In order to make it more convenient to use, the possibility of the rotating screw 2 being offset during use is reduced. Figure 1 As shown, the utility model is further provided with a reinforcing nut 7, which is arranged on the main board 1 and located above the threaded through hole, and the rotating screw 2 is arranged through the reinforcing nut 7. Furthermore, a guide sleeve 8 is also provided, which is vertically connected and arranged below the main board 1, and the rotating screw 2 is arranged through the guide sleeve 8.

[0028] When the encoder is disassembled, the rotating screw 2 needs to be pressed against the dummy shaft of the motor shaft. In order to reduce damage to the dummy shaft of the motor shaft, the lower end of the rotating screw 2 is arc-shaped, which makes it easier for the rotating screw 2 to rotate and facilitates its use.

[0029] In summary, when disassembling the encoder, first adjust the width of the clamping cavity 4 according to the cross-sectional size of the encoder by connecting the bolts 5, the left and right bar-shaped through holes 11 and the clamping plate 3, so that the width of the clamping cavity 4 is slightly larger than the cross-sectional size of the encoder; then put the clamp on the encoder and clamp the encoder; finally, the disassembler rotates the rotating screw 2 through the handle 6, so that the rotating screw 2 is against the false shaft of the motor shaft, and then continues to rotate the rotating screw 2 until the encoder is loosened from the false shaft of the motor shaft. It can be seen that the encoder disassembly device of the utility model has a simple structure and is easy to use. It can significantly improve the disassembly efficiency of the encoder, effectively reduce the labor intensity, and reduce the possibility of damage to the encoder. In addition, the width of the clamping cavity 4 of the encoder disassembly device of the utility model can be adjusted, which is suitable for the disassembly of encoders of different sizes and is conducive to large-scale use.
