Description

Technical Field

[0001] This utility model belongs to the field of motor repair technology, and specifically relates to a positioning device for motor repair. Background Technology

[0002] During prolonged use, motors require regular inspection and maintenance to ensure their proper functioning. Currently, motor maintenance involves operators disassembling the motor parts and placing the main motor housing flat on a workbench. This method is inconvenient for securing different motor housings on the workbench and for adjusting their rotation during maintenance. Furthermore, the wiring harnesses at the ends of the motor housing tend to protrude during maintenance, making it difficult to effectively constrain and position the harnesses at various locations. This results in the wiring harnesses being scattered throughout the motor maintenance area, impacting work efficiency. Utility Model Content

[0003] This invention provides a positioning device for motor repair, which improves work efficiency.

[0004] This utility model provides the following technical solution: it includes an external support assembly and a clamping assembly. The external support assembly includes a base, a top plate, and a support shell. The top plate and the support shell are positioned sequentially from top to bottom on the top of the base. The clamping assembly includes two elastic pressure plates and two fastening screws. The fastening screws are screwed into the inside of the top plate. The elastic pressure plates are vertically movable above the support shell through the corresponding fastening screws. Several wire harness assemblies are provided on the outer side of both the support shell and the elastic pressure plates. The wire harness assembly includes a wire harness shell and a flexible connecting rod. The wire harness shell is positioned on the outer side of the corresponding support shell or the elastic pressure plate through the flexible connecting rod.

[0005] The support shell is fixedly connected to the top of the base, and the top plate is fixedly connected above the base.

[0006] A connecting plate is provided between the elastic pressure plate and the fastening screw, and the connecting plate is located in the middle of the outer wall of the elastic pressure plate.

[0007] The bottom of the connecting plate is fixedly connected to the outer walls of the two elastic pressure plates, and the bottom end of the fastening screw is rotatably connected to the top of the connecting plate.

[0008] The flexible connecting rod is fixedly connected to the outer wall of the wire harness shell, and several wire harness assemblies on the outside of the support shell are located at both ends of the support shell.

[0009] The other end of the flexible connecting rod located on the outside of the support shell is fixedly connected to the outer wall of the support shell, and the other end of the flexible connecting rod located on the outside of the elastic pressure plate is fixedly connected to the outer wall of the elastic pressure plate.

[0010] The inner side of the pressing assembly is provided with an internal support assembly, which includes a semi-circular support block and a fixing screw.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a combined external support assembly to support the motor to be repaired on a workbench. The support shell holds the main housing of the motor to be repaired from below. Two elastic pressure plates in the upper position move downward through rotating fastening screws to press the main housing of the motor from above. The semi-circular support block on the internal support assembly supports the main housing of the motor from the inside, which can simultaneously tighten and position the main housing of the motor from the inside and outside. The two ends of the elastic pressure plate can be bent inward to change the state of the elastic pressure plate. After the elastic pressure plate moves upward and separates from the main housing of the motor, the main body of the motor can rotate along the semi-circular support block. The operation is simple, which facilitates the tightening and positioning of different motor main housings on the support shell and the rotation adjustment during the repair process.

[0013] 2. In this utility model, multiple wire harnessing assemblies are provided at both ends of the support shell and on the two elastic pressure plates. The wire harness shell provides space for scattered wire harnesses to enter. The wire harness shell is squeezed to secure and constrain the wire harness. The wire harness shell and the wire harness are moved outward by a flexible connecting rod that can be bent, so as to remove them from the maintenance area of ​​the motor main housing. This can effectively constrain and position the wire harnesses at various positions, avoid the wire harnesses from being scattered in the motor maintenance area, improve the motor maintenance effect, and increase work efficiency.

[0020] Please see Figures 1-4 The present invention provides the following technical solution: it includes an outer shell support assembly 1 and a clamping assembly 2. The outer shell support assembly 1 includes a base 11, a top plate 12 and a support shell 13. The top plate 12 and the support shell 13 are positioned on the top of the base 11 from top to bottom. The clamping assembly 2 includes two elastic pressure plates 21 and two fastening screws 22. The fastening screws 22 are screwed into the inside of the top plate 12. The elastic pressure plates 21 are vertically movable above the support shell 13 through the corresponding fastening screws 22. Several wire harness assemblies 3 are provided on the outer side of the support shell 13 and the elastic pressure plates 21. The wire harness assembly 3 includes a wire harness shell 31 and a flexible connecting rod 32. The wire harness shell 31 is positioned on the outer side of the corresponding support shell 13 or elastic pressure plate 21 through the flexible connecting rod 32.

[0021] In this embodiment: the outer shell support assembly 1 is used to support the motor to be repaired. The outer shell support assembly 1 consists of a base 11, a top plate 12 and a support shell 13. The support shell 13 is fixedly connected to the top of the base 11, and the top plate 12 is fixedly connected above the base 11. The top plate 12 and the support shell 13 are stably connected to the top of the base 11. The base 11 is placed on the workbench, and the support shell 13 supports the main shell of the motor to be repaired on the top of the base 11.

[0022] The clamping assembly 2 is connected to the inner side of the top plate 12. The clamping assembly 2 consists of two elastic pressure plates 21 and two fastening screws 22. A connecting plate 23 is provided between the elastic pressure plates 21 and the fastening screws 22. The connecting plate 23 is located in the middle of the outer wall of the elastic pressure plates 21. The bottom of the connecting plate 23 is fixedly connected to the outer wall of the two elastic pressure plates 21. The bottom end of the fastening screw 22 is rotatably connected to the top of the connecting plate 23, stably connecting the two elastic pressure plates 21, the two fastening screws 22, and the connecting plate 23. The fastening screws 22 are screwed into the inside of the top plate 12, stably connecting the clamping assembly 2 to the top plate 12, so that the two elastic pressure plates 21 are positioned directly above the support shell 13. By rotating the two fastening screws 22, the connecting plate 23 can move vertically above the support shell 13, carrying the two elastic pressure plates 21, to adjust the position of the elastic pressure plates 21. The elastic pressure plate 21 moves vertically downward to gradually approach the upper half of the motor main housing placed inside the support shell 13. The elastic pressure plate 21 presses the upper half of the motor main housing from the outside to cooperate with the support shell 13 to complete the tight fixing operation of the motor on the worktable.

[0023] The combined outer shell support assembly 1 supports the motor to be repaired on the workbench. The support shell 13 supports the main housing of the motor to be repaired from below. The two elastic pressure plates 21 in the upper position are pushed downward by the connecting plate 23 under the control of the rotating fastening screw 22, so that the elastic pressure plates 21 press the main housing of the motor from above, so as to securely fix the main housing of the motor on the workbench. The two ends of the elastic pressure plates 21 can be bent inward to change the state of the elastic pressure plates 21. After the elastic pressure plates 21 move upward and separate from the main housing of the motor, the main housing of the motor can be rotated inside the support shell 13, so as to facilitate the fixing and positioning of different motor main housings on the support shell 13 and the rotation adjustment during the maintenance process.

[0024] An internal support assembly 4 is provided inside the clamping assembly 2. The internal support assembly 4 consists of a semi-circular support block 41 and a fixing screw 42. The fixing screw 42 is screwed inside the top plate 12. The semi-circular support block 41 is located between two elastic pressure plates 21. The bottom end of the fixing screw 42 is rotatably connected to the top of the semi-circular support block 41, so that the internal support assembly 4 is stably connected between the support shell 13 and the elastic pressure plate 21. By rotating the fixing screw 42, the position of the semi-circular support block 41 between the elastic pressure plates 21 can be adjusted so that the semi-circular support block 41 can press against the motor main housing from the inside of the motor main housing, thereby improving the clamping and positioning effect of the motor main housing.

[0025] Several wire harness assemblies 3 are respectively disposed on the outer sides of the support shell 13 and the elastic pressure plate 21. Each wire harness assembly 3 consists of a wire harness shell 31 and a flexible connecting rod 32. The flexible connecting rod 32 is fixedly connected to the outer wall of the wire harness shell 31, stably combining the wire harness shell 31 and the flexible connecting rod 32. Several wire harness assemblies 3 on the outer side of the support shell 13 are respectively located at both ends of the support shell 13. The other end of the flexible connecting rod 32 located on the outer side of the support shell 13 is fixedly connected to the outer wall of the support shell 13, and the other end of the flexible connecting rod 32 located on the outer side of the elastic pressure plate 21 is fixedly connected to the outer wall of the elastic pressure plate 21, thus stably connecting several wire harness shells 31 to the outer side of the corresponding support shell 13 or elastic pressure plate 21. The wire harness shell 31 provides space for loose wire harnesses to enter. The wire harness shell 31 has an opening to facilitate the insertion of wire harnesses into the wire harness shell 31. The wire harness shell 31 is deformed by squeezing it from the outside, thereby securing and restraining the wire harnesses through the wire harness shell 31. Pulling the cable harness housing 31 from the outside allows the flexible connecting rod 32 to move the cable harness housing 31 and the cable harness outward, thus removing them from the maintenance area of ​​the main motor housing. This effectively constrains and positions the cable harness at various locations, preventing it from becoming scattered in the motor maintenance area, thereby improving the motor maintenance effect and work efficiency.
