Description

Technical Field

[0001] The utility model belongs to the technical field of maintenance tools and relates to a motor maintenance auxiliary tool. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. It plays a key role in production and is widely used to drive various production machinery and equipment. For example, a motor can drive a water dispenser, a blower, a conveyor, a CNC machine tool, a tram, and many other equipment. However, during the use of the motor, due to long-term continuous use and improper operation by the user, the motor may fail, which not only affects the stable operation of the motor, but also causes major accidents. Therefore, when the motor fails, it should be repaired regularly to keep the motor in good operating condition and ensure safety and production needs.

[0003] During maintenance, it is necessary to disassemble the motor bearings, backrest wheels and other components. Traditional motor disassembly is mostly done manually, but it is time-consuming, labor-intensive and inefficient. Therefore, tools for motor disassembly have emerged. For example, the Chinese patent document with patent application number 202420053181.6 discloses a stepper motor disassembly tool, including a handle, a screw and a nut. One end of the screw is connected to the handle, and the nut has a first internal thread and a second internal thread of different diameters. The first internal thread matches the screw, and the second internal thread matches the external thread on the motor main shaft. When the motor needs to be disassembled, just insert the top of the screw into the top of the main shaft of the stepper motor and dock it with it, connect the nut with the external thread on the motor main shaft, and turn the handle to easily disassemble the motor. Although the disassembly tool can disassemble the motor main shaft, it is difficult to disassemble large and medium-sized motor bearings and other components, which is not conducive to motor maintenance, making the maintenance work time long and inefficient.

[0029] During implementation, the material of the clamping member 10 , the material of the support column 20 and the material of the jacking member 30 are all metal; preferably, the material is all steel.

[0030] The plate surface of the clamping member 10 and the plate surface of the jacking member 30 are both placed horizontally, and the jacking member 30 is located above the clamping member 10, the support column 20 is placed between the clamping member 10 and the jacking member 30, the axial direction of the support column 20 is perpendicular to the plate surface of the clamping member 10, the upper end of the support column 20 is connected to the jacking member 30, and the lower end of the support column 20 is connected to the clamping member 10.

[0031] See also Figure 3A slot 101 is provided at the center position of the holder 10 in the horizontal direction. The length of the slot 101 extends from the front end side wall of the holder 10 to the center position of the holder 10, that is, the length direction of the slot 101 is consistent with the longitudinal horizontal direction of the holder 10. The width of the slot 101 is slightly wider than the diameter of the motor shaft, so that the holder 10 can be clamped on the motor shaft through the slot 101.

[0032] In this embodiment, the slot 101 is a U-shaped slot or a rectangular slot. Preferably, the slot 101 is a U-shaped slot. Since the U-shaped portion of the slot 101 and the motor shaft are both arc-shaped, the contact area is large and the clamping is tighter.

[0033] In this embodiment, there are at least two support columns 20 , and the plurality of support columns 20 are evenly distributed around a line connecting the center point of the clamping member 10 and the midline point of the pushing member 30 .

[0034] Preferably, there are two support columns 20, which are arranged on the left and right sides of the slot 101. One end of the two support columns 10 is connected to the clamping member 10, and the other end is connected to the jacking member 30. The connection can be made by flange structure or welding.

[0035] Preferably, the support columns 20 may be three, four or more, and are designed according to the size of the clamping member 10 and the jacking member 30 to ensure support stability.

[0036] In this embodiment, the slot 101 of the clamping member 10 is clamped on the motor rotor main shaft behind the motor bearing, the jacking component of the jack is located in the area between the clamping member 10 and the jacking member 30, and the support rod 20 is located outside the jacking component of the jack, and the axial direction of the jacking component is the same as the axial direction of the support rod 20; at the same time, the ejection end of the jacking component is opposite to the lower surface of the jacking member 30, and the jack is working, the jacking component extends out to drive the jacking member 30 to move forward, and then the clamping member 10 pushes the bearing on the motor rotor main shaft to move forward, thereby removing the bearing from the motor, saving time and effort, shortening the time, and increasing the disassembly speed, thereby improving the efficiency of motor maintenance work.

[0037] Example 2

[0038] See also Figure 1 and Figure 2 On the basis of Example 1, the motor maintenance auxiliary tool provided in this embodiment further includes a vertical plate 40 located above the jacking piece 30 and connected to the jacking piece 30 , and the vertical plate 40 is perpendicular to the jacking piece 30 .

[0039] In this embodiment, the material of the vertical plate 40 is metal; preferably, the material is steel.

[0040] In this embodiment, the vertical plate 40 is placed above the jacking member 30, the plate surface of the vertical plate 40 is perpendicular to the plate surface of the jacking member 30, and the placement position of the vertical plate 40 must ensure that the projection position of the vertical plate 40 on the clamping member 10 is opposite to the notch position of the clamping slot 101, that is, the rear end side of the jacking member 30 is connected to the vertical plate 40, the front end of the jacking member 30 is located above the clamping slot 101, the lower end of the vertical plate 40 is connected to the jacking member 30 to form an L-shaped structure, and the upper end of the vertical plate 40 is provided with a handheld portion 50. In this embodiment, in the process of the jacking member 30 being pushed forward by the jacking member of the jacking member, the handheld portion 50 at the front end of the jacking member 30 applies a pulling force to the jacking member 30, thereby accelerating the jacking speed, making disassembly and assembly easier, and enhancing maintenance efficiency.

[0041] Example 3

[0042] See also Figure 2 and Figure 3 On the basis of Example 1, the motor maintenance auxiliary tool provided in this embodiment further includes an anti-wear pad layer 102 arranged on the upper surface of the clamping member 10 and the inner groove wall of the clamping groove 101.

[0043] During use of the motor maintenance auxiliary tool, when the slot 101 is stuck on the rotating shaft, the upper surface of the clamping part 10 contacts the bearing, and the inner wall of the slot 101 contacts the outer wall of the rotating shaft. Since the clamping part 10 is made of metal, friction loss will be generated during jacking. Therefore, providing an anti-wear pad layer 102 can prevent the clamping part 10 from wearing the motor components during jacking, thereby ensuring the reuse of the motor components.

[0044] In the utility model, motor maintenance auxiliary tools of different specifications can be made according to the size of the motor rotor shaft diameter.
