[0031] An electric motor is a device that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or a distributed stator winding to generate a magnetic field and a rotating armature or rotor. Electric motors have been widely used in various aspects of industry and life. With the increasing number and frequency of use of electric motors, the disassembly and maintenance of electric motors has gradually attracted people's attention.

[0032] When a motor breaks down, the staff usually puts it on a workbench and then disassembles it for maintenance. During the maintenance process, a fixing device is needed to fix the motor to facilitate the staff to disassemble it. When the existing fixing device is used to disassemble different parts of the motor, the motor needs to be taken out of the fixing device and then manually turned over, which is time-consuming and labor-intensive, and reduces the efficiency of the motor maintenance work to a certain extent.

[0033] In order to solve the above problems, the utility model proposes a fixing device 1000 for disassembling and repairing an electric motor, comprising a base 1, a rotating component 2 and a clamping component 3, wherein the rotating component 2 comprises a fixed back plate 21, and the fixed back plate 21 is rotatably connected to the base 1; the clamping component 3 comprises two clamping members 31, each clamping member 31 is connected to the fixed back plate 21, and the two clamping members 31 enclose a clamping space to clamp the motor.

[0034] The technical solution of the utility model is to set the clamping assembly 3 on the fixed back plate 21, use two clamping members 31 to clamp the two sides of the motor to fix the motor, and drive the motor to rotate relative to the base 1 by rotating the fixed back plate 21, so that the motor can be flipped during maintenance, reduce the labor intensity of maintenance personnel when repairing the motor, and improve maintenance efficiency.

[0035] In an optional embodiment, in order to facilitate the clamping member 31 to clamp the motor, the clamping assembly 3 also includes a clamping screw 32, the clamping screw 32 is connected to the fixed back plate 21, the clamping screw 32 has a first end and a second end along the axial direction, the peripheral walls of the first end and the second end are provided with external threads with opposite rotation directions, and the two clamping members 31 are provided with internal threads corresponding to the external threads, so that the two clamping members 31 can be respectively screwed to the two ends of the clamping screw 32, and when the clamping screw 32 rotates relative to the fixed back plate 21, the two clamping members 31 can move closer to or farther away from each other. Please refer to Figures 1 to 4 Two slide grooves are formed on the fixed back plate 21, and the clamping screw 32 is arranged on the fixed back plate 21 and penetrates the slide groove. The external thread on the clamping screw 32 is exposed on the fixed back plate 21, so that when the clamping member 31 is connected with the clamping screw 32 by threading, the clamping member 31 can be moved left and right relative to the extension direction of the clamping screw 32 by rotating the clamping screw 32. When the motor needs to be fixed, the motor is lifted by a hoisting device such as a crane or a crane and moved between the two clamping members 31, and the clamping screw 32 is rotated to make the two clamping members 31 close to each other to clamp the opposite sides of the motor to achieve the fixation of the motor. In addition, by adjusting the distance between the two clamping members 31 by the clamping screw 32, it is also convenient to fix motors of various sizes, thereby improving the adaptability of the fixing device 1000 for disassembly and maintenance of the motor. Optionally, a handle or a knob or other components that are convenient for leveraging can be set at the end of the clamping screw 32 to facilitate the maintenance personnel to rotate and adjust the clamping screw 32.

[0036] Furthermore, to ensure that the clamping member 31 has sufficient length to clamp the motor, the clamping member 31 includes a clamping plate 311 and a connecting rod 312. The clamping plate 311 is connected to one end of the connecting rod 312 away from the fixed back plate 21. The connecting rod 312 is connected to the clamping screw 32. The clamping plate 311 is used to clamp the motor. Figure 1 and Figure 2 The connecting rod 312 is arranged perpendicular to the fixed back plate 21, and the clamping plate 311 is connected to one end of the connecting rod 312 away from the fixed back plate 21, so that there is enough length between the clamping plate 311 and the fixed back plate 21 to accommodate the motor, so that the clamping plate 311 can clamp the middle part of the motor and keep the fixing device 1000 for disassembly and maintenance of the motor balanced when clamping and fixing the motor.

[0037] Furthermore, each clamping plate 311 has a clamping surface for clamping the motor, and the clamping surface is arranged in an arc shape. Figure 1 and Figure 2 Since the shape of the motor is cylindrical as a whole and the peripheral wall of the motor is arc-shaped, in order to make the clamping plate 311 fully contact with the motor when clamping the motor to ensure the stability of the clamping, the shape of the clamping surface is set to be arc-shaped to correspond with the peripheral wall of the motor, so that the clamping can be more firmly. Optionally, the clamping plate 311 can be an arc-shaped plate with an overall arc shape, or a block structure, and a corresponding match with the peripheral wall of the motor is achieved by opening an arc-shaped matching groove on the block structure. The specific selection can be made according to actual needs.

[0038] In an optional embodiment, in order to realize radial rotation of the motor, the clamping assembly 3 further includes two rotation dampers 33, one rotation damper 33 is arranged on a connecting rod 312 and connected to a clamping plate 311, so that the clamping plate 311 can rotate along the axial direction of the line connecting the two rotation dampers 33. Figure 1 and Figure 2 The rotary damper 33 is penetrated by a connecting rod 312 and connected to the connecting plate, so that the clamping plate 311 can rotate relative to the axial direction of the line connecting the two rotary dampers 33, thereby realizing that the motor can rotate radially, which is convenient for maintenance personnel to flip the motor. By setting a pair of rotary dampers 33, the stability of the clamping plate 311 during rotation is improved, and the safety of the motor during radial flipping is guaranteed.

[0039] In an optional embodiment, in order to reduce the labor intensity when flipping the motor, the rotating assembly 2 further includes a rotating motor 22, which is disposed on the base 1, and the output end of the rotating motor 22 is connected to the fixed back plate 21 to drive the fixed back plate 21 to rotate relative to the base 1. The rotating motor 22 drives the fixed back plate 21 to rotate, thereby driving the clamping member 31 disposed on the fixed back plate 21 to rotate, realizing automatic flipping of the motor and reducing the labor intensity of the maintenance personnel. Optionally, the output shaft of the rotating motor 22 can be directly connected to the central axis of the fixed back plate 21, so that the rotating motor 22 drives the motor fixed on the clamping member 31 to rotate.

[0040] In another optional embodiment, the rotating assembly 2 further includes a gear assembly 23, the gear assembly 23 includes a rotating internal gear 231 and a driving gear 232, the rotating internal gear 231 is connected to the side of the fixed back plate 21 facing away from the clamping member 31, the driving gear 232 is connected to the output end of the rotating motor 22, and the rotating internal gear 231 is meshed with the driving gear 232. Please refer to Figure 2 and Figure 5In this embodiment, the rotating internal gear 231 is an internal meshing gear, which can reduce the size of the fixing device 1000 for disassembling and repairing the motor. By setting the driving gear 232 on the inner side of the rotating internal gear 231 and meshing with the rotating internal gear 231, the rotating motor 22 drives the axial driving gear 232 to rotate and further drives the rotating internal gear 231 to select, thereby driving the motor to flip. Optionally, the rotating internal gear 231 can also be an external meshing gear. By setting the driving motor and the driving gear 232 on the outer periphery of the rotating internal gear 231, the rotating internal gear 231 and the driving gear 232 are externally meshed to achieve transmission, which can also achieve the same effect. The specific selection can be made according to actual needs.

[0041] In an optional embodiment, in order to support the fixed back plate 21, the base 1 includes a bottom plate 11 and a support plate 12, the support plate 12 is connected to the bottom plate 11 in a vertical direction, and the fixed back plate 21 is connected to the support plate 12. By setting the fixed back plate 21 on the support plate 12 and being rotatable relative to the support plate 12, the clamping member 31 can be kept at a certain height from the ground, so that when the clamping member 31 clamps the motor, the motor can be kept in a suspended state, so as to realize the rotation of the motor in the axial or radial direction.

[0042] Furthermore, the support plates 12 include two, each support plate 12 is spaced apart from the bottom plate 11, and each support plate 12 is formed with a mounting hole, and the two ends of the fixed back plate 21 along the axial direction are respectively mounted in the mounting holes. Figure 1 and Figure 2 The two support plates 12 are spaced apart on the bottom plate 11, and the two ends of the fixed back plate 21 are respectively clamped in the mounting holes so that the fixed back plate 21 can rotate in the mounting hole, thereby realizing that the fixed back plate 21 can be rotated and adjusted relative to the base 1, thereby achieving the effect of flipping the motor.

[0043] In an optional embodiment, the fixing device 1000 for disassembling and repairing the motor further includes a rotating button 4, which is disposed on the bottom plate 11 and is electrically connected to the rotating motor 22. Figure 1 and Figure 4 The rotating button 4 is arranged on the base 1, and is electrically connected to the rotating motor 22 through the rotating button 4, so as to realize the control of the rotating motor 22 through the rotating button 4, so that the maintenance personnel can control the flip angle at any time through the rotating button 4 when repairing the motor. In other embodiments, a control device such as a remote controller can also be used to realize the control of the rotating motor 22 through wireless or wired control, which can be selected according to actual needs.
