Description

Technical Field

[0001] The utility model relates to the technical field of motor repair auxiliary tools, and more specifically to a motor coupling sleeve remover. Background Art

[0002] In the fields of chemical industry, metallurgy, brewing, ceramics, environmental protection, etc., the operation of equipment such as filter press pumps, mixing reducers, ball mill bridges, etc. depends on the motor to connect the pump to run smoothly. The connection between the pump and the motor depends on the coupling. The coupling is tightly connected on the motor bearing, and the coupling sleeve is mounted on the motor rotor.

[0003] There are two common methods for removing motor coupling sleeves: manual forced disassembly and tool-assisted disassembly. Manual forced disassembly can easily damage the equipment and the spindle. Tool-assisted disassembly uses the relationship between action and reaction forces to remove the sleeve (using patent CN207853698U as an example). However, this method has the problem of poor adaptability to sleeves of different sizes and generally requires two people to work together: one to fix the position of the auxiliary tool and the other to apply the force. Therefore, it also has the problems of cumbersome operation and low disassembly efficiency. Utility Model Content

[0004] The purpose of the utility model is: in order to solve the above technical problems, the utility model provides a motor coupling sleeve remover, which can be operated by one person when removing the coupling sleeve. The device is portable and has the characteristics of strong adaptability, simple operation and high disassembly efficiency.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] A motor coupling sleeve remover, comprising:

[0007] A shaft sleeve fixing frame, the shaft sleeve fixing frame includes a front side plate, a rear side plate, an upper connecting frame, and a lower connecting frame. The front side plate and the rear side plate are fixed between the upper connecting frame and the lower connecting frame. A screw barrel is fixedly connected through the front side plate, and an arched opening is opened on the rear side plate.

[0008] A top angle rod, wherein the top angle rod includes a screw rod, and the screw rod is threadedly connected to the screw barrel;

[0009] A backing plate is provided with a limited opening.

[0010] In order to facilitate the staff to control the position of the sleeve fixing frame, as a preferred embodiment of the motor coupling sleeve remover of the present invention, the sleeve fixing frame further includes a handle, which is fixed to the outer side of the upper connecting frame.

[0011] In order to facilitate the rapid and convenient screwing of the top angle rod, as a preferred motor coupling sleeve remover of the utility model, the top angle rod also includes a hexagonal nut and a tip, and the hexagonal nut and the tip are fixedly connected to the two ends of the screw respectively.

[0012] In order to facilitate the placement of the pad in the sleeve fixing frame, as a preferred motor coupling sleeve remover of the present invention, the length of the pad is smaller than the length of the front side plate and the rear side plate, and the thickness of the pad is smaller than the distance between the front side plate and the rear side plate.

[0013] In order to reduce the possibility of deformation of the two side plates, as a preferred embodiment of the motor coupling sleeve remover of the present invention, the front side plate, the rear side plate and the backing plate are all made of manganese steel.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. By starting the electric wrench and screwing the top angle rod, the screw is threadedly connected to the screw barrel, and one end of the screw abuts against the end of the motor rotor, so that the sleeve fixing frame moves away from the motor, and drives the coupling and sleeve to move, thereby separating the coupling, sleeve and motor rotor, achieving the effect of quickly disassembling the coupling sleeve;

[0016] 2. When the outer extension of the sleeve is too long, resulting in the distance between the coupling and the motor rotor being too far, the top angle rod is not long enough. By placing a pad between the coupling and the rear side plate, the length of the screw located on the outside of the front side plate can be increased. Therefore, pads of different thicknesses can be selected according to the different sizes of sleeves to enhance the adaptability of the sleeve remover. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1-3 , the utility model provides the following technical solutions:

[0024] A motor coupling sleeve remover, comprising:

[0025] The shaft sleeve fixing frame 1 includes a front side plate 101, a rear side plate 102, an upper connecting frame 103, and a lower connecting frame 104. The front side plate 101 and the rear side plate 102 are fixed between the upper connecting frame 103 and the lower connecting frame 104. A screw barrel 1011 is fixedly connected and penetrated on the front side plate 101, and an arched opening 1021 is opened on the rear side plate 102;

[0026] The top angle rod 2 includes a screw rod 201, and the screw rod 201 is threadedly connected to the screw barrel 1011;

[0027] The backing plate 3 is provided with a limited opening 301 .

[0028] In this embodiment: the coupling 5 is fixedly connected to the sleeve 501, so that the coupling 5 is located between the front and rear side plates, the arched opening 1021 on the rear side plate 102 is stuck on the outside of the sleeve 501, the top angle rod 2 passes through the front side plate 101, and the screw 201 is threadedly connected to the screw barrel 1011, and one end of the screw 201 is located in the sleeve fixing frame 1 and is movably engaged with the center position of the coupling 5, and the end of the screw 201 is in contact with the end of the motor rotor 4. When the top angle rod 2 is screwed, due to the action of the screw barrel 1011, the sleeve fixing frame 1 moves away from the motor, thereby driving the coupling 5 and the sleeve 501 to move, thereby separating the coupling 5, the sleeve 501 and the motor rotor 4.

[0029] As a technical optimization solution of the present invention, the shaft sleeve fixing frame 1 further includes a handle 105 , which is fixed to the outer side of the upper connecting frame 103 .

[0030] In this embodiment, by providing the handle 105 , a worker can hold the shaft sleeve fixing frame 1 at any time, so as to carry the integral remover and install it with the shaft sleeve 501 .

[0031] As a technical optimization solution of the present invention, the top angle rod 2 further includes a hexagonal nut 202 and a tip 203 , and the hexagonal nut 202 and the tip 203 are fixedly connected to the two ends of the screw rod 201 respectively.

[0032] In this embodiment: by fixing a tip 203 at the end of the screw 201 close to the coupling 5, the end of the screw 201 can be easily clamped with the center of the coupling 5; by setting a hexagonal nut 202 at the end of the screw 201 away from the coupling 5, the staff can quickly screw the screw 201, thereby improving the disassembly efficiency of the coupling sleeve.

[0033] As a technical optimization solution of the present invention, the length of the pad 3 is smaller than the length of the front side plate 101 and the rear side plate 102, the thickness of the pad 3 is smaller than the distance between the front side plate 101 and the rear side plate 102, and the material of the front side plate 101, the rear side plate 102 and the pad 3 are all manganese steel.

[0034] In this embodiment: by setting the length and thickness of the pad 3 to ensure that the pad 3 can be placed in the sleeve fixing frame 1, the appropriate pad 3 can be selected according to the size of the sleeve 501. When the outer extension of the sleeve 501 is too long, which causes the distance between the coupling 5 and the motor rotor 4 to be too far, the top angle rod 2 has the problem of insufficient length. By placing a pad between the coupling 5 and the rear side plate 102, the length of the screw 201 located on the outside of the front side plate 101 can be increased; by setting the two side plates and the pad 3 to be made of manganese steel, the strength of the force-bearing part of the remover can be increased, and the possibility of deformation of the remover can be reduced.

[0035] The working principle and use process of this utility model:

[0036] 1. Position the coupling 5 between the front and rear side plates. The arched opening 1021 on the rear side plate 102 is clamped on the outside of the shaft sleeve 501. The top angle rod 2 passes through the front side plate 101. The screw 201 is threadedly connected to the screw barrel 1011. One end of the screw 201 located in the shaft sleeve fixing frame 1 is movably engaged with the center of the coupling 5, and the end of the screw 201 abuts against the end of the motor rotor 4.

[0037] 2. Install the hexagonal socket 601 on the output end of the electric wrench 6. Install the hexagonal socket 601 and the hexagonal nut 202. Start the electric wrench 6 to screw the top angle rod 2. Due to the action of the screw barrel 1011, the sleeve fixing frame 1 moves away from the motor, thereby driving the coupling 5 and the sleeve 501 to move, thereby separating the coupling 5, the sleeve 501 and the motor rotor 4.

[0038] 3. When the outer extension of the sleeve 501 is too long, resulting in the distance between the coupling 5 and the motor rotor 4 being too far, the top angle rod 2 has the problem of insufficient length. By placing a pad between the coupling 5 and the rear side plate 102, the length of the screw 201 located on the outside of the front side plate 101 can be increased, so that pads 3 of different thicknesses can be selected for use according to the different sizes of the sleeve 501.

[0039] The above is a detailed introduction to the technical solutions provided by the embodiments of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention.
