Description

Technical fields:

[0001] This utility model relates to the field of motor processing technology, and more specifically to a clamping structure for manual inspection of motor housing. Background technology:

[0002] An electric motor generally includes a rotor assembly, a stator assembly, and a housing. The housing is usually made by casting. After casting, it still needs to be machined, such as machining holes for connection and milling some mating end faces.

[0003] After machining is completed, the outer wall surface needs to be inspected as a whole, the surface of the machined area needs to be inspected, and the end face needs to be manually polished to ensure that the surface meets the machining requirements.

[0004] The current method involves manually rotating the casing for general inspection. After the inspection is completed, the end face is polished. At this point, after polishing part of the end face, the casing is held with both hands and rotated at a certain angle. Then, it is sanded again. This method is inefficient, as manually rotating the casing is inconvenient. Moreover, due to the weight of the casing, manual operation is very physically demanding and involves a large amount of manual labor. Utility model content:

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a clamping structure for manual inspection of motor housing. It can automatically clamp the motor housing, and then rotate the motor housing by rotating the horizontal rotating plate with one hand to facilitate observation and inspection of its surface. At the same time, it can also rotate the horizontal rotating plate with one hand and hold sandpaper to polish the end face of the motor housing. It is easy to operate, greatly reduces the amount of manual labor, and has good performance.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A clamping structure for manual inspection of motor housing includes a fixed frame. A vertical through hole is formed in the middle of the top plate of the fixed frame. A rotating block is located in the vertical through hole and is movably connected to the top plate of the fixed frame through a bearing. A lifting cylinder is fixed in the middle of the bottom surface of the rotating block. The top end of the push rod of the lifting cylinder extends out of the top surface of the rotating block and is fixed with a conical push block. A horizontal rotating plate is fixed in the top surface of the rotating block. A central through hole is formed in the middle of the horizontal rotating plate. The conical push block is inserted into the central through hole.

[0008] Multiple sector-shaped blocks are placed on the top surface of the middle part of the horizontal rotating plate. The inner sidewall of all sector-shaped blocks is formed with a conical wall. A conical pushing block is located between all sector-shaped blocks. The outer sidewall of the conical pushing block presses against the corresponding conical wall. The bottom surface of the motor housing to be processed presses against the top surface of the horizontal rotating plate. The outer sidewall of all sector-shaped blocks presses against the lower inner sidewall of the motor housing.

[0009] All of the aforementioned sector blocks have an elastic anti-slip layer fixed to their outer sidewalls, which presses against the lower inner sidewall of the motor housing.

[0010] The conical wall and the conical push block have a small outer diameter at the top and a large outer diameter at the bottom.

[0011] The bottom surface of the sector block is fixed with a guide block. The upper part of the inner sidewall of the central through hole is formed with multiple outwardly radially extending guide grooves. The cross-section of the guide groove is convex. The width of the upper groove is smaller than the width of the lower groove. The guide block is inserted into the guide groove. The guide block and the guide groove cooperate with each other. The upper part is a narrow width part and the lower part is a wide width part. The upper part is inserted into the upper groove of the guide groove and the lower part is inserted into the lower groove.

[0012] Multiple inner baffles are fixed on the inner wall of the central through hole, and the inner baffles block the inner end of the corresponding guide groove.

[0018] Figure 3 This is a partial top view of the horizontally rotated plate. Detailed implementation method:

[0019] For example, see below. Figures 1 to 3As shown, a clamping structure for manual inspection of motor housing includes a fixed frame 10. A vertical through hole is formed in the middle of the top plate of the fixed frame 10. A rotating block 20 is located in the vertical through hole and is movably connected to the top plate of the fixed frame 10 through a bearing. The top surface of the rotating block 20 is higher than the top surface of the top plate of the fixed frame 10. A lifting cylinder 21 is fixed in the middle of the bottom surface of the rotating block 20. The top end of the push rod of the lifting cylinder 21 extends out of the top surface of the rotating block 20 and is fixed with a conical push block 22. A horizontal rotating plate 30 is fixed in the top surface of the rotating block 20. A central through hole 31 is formed in the middle of the horizontal rotating plate 30. The conical push block 22 is inserted into the central through hole 31.

[0020] Multiple sector blocks 40 are placed on the top surface of the middle part of the horizontal rotating plate 30. The central axis of all sector blocks 40 coincides with the vertical central axis of the conical push block 22. The inner sidewall of all sector blocks 40 is formed with a conical wall surface. The conical push block 22 is located between all sector blocks 40. The outer sidewall of the conical push block 22 presses against the corresponding conical wall surface. The bottom surface of the motor housing 100 to be processed presses against the top surface of the horizontal rotating plate 30. The outer sidewall of all sector blocks 40 presses against the lower inner sidewall of the motor housing 100. At this time, the outer sidewall of all sector blocks 40 is in the same circular circle. The central axis of the circular circle coincides with the central axis of all sector blocks 40.

[0021] An elastic anti-slip layer 41 is fixed to the outer wall of all the aforementioned sector blocks 40, which presses against the lower inner wall of the motor housing 100. The elastic anti-slip layer 41 can increase the pressure of the outer wall of the sector block 40 pressing against the lower inner wall of the motor housing 100.

[0022] Furthermore, the outer diameter of the top end of the conical wall and the outer diameter of the conical push block 22 are small, while the outer diameter of the bottom end is large.

[0023] The bottom surface of the sector block 40 is fixed with a guide block 42. The upper part of the inner sidewall of the central through hole 31 is formed with multiple outwardly radially extending guide grooves 32. The cross-section of the guide groove 32 is convex. The width of the upper groove is smaller than the width of the lower groove. The guide block 42 is inserted into the guide groove 32. The guide block 42 and the guide groove 32 cooperate with each other. The upper part is a narrow width part and the lower part is a wide width part. The upper part is inserted into the upper groove of the guide groove 32. The two side walls of the upper part are close to the corresponding two side walls of the upper groove of the guide groove 32. The lower part is inserted into the lower groove. The two side walls of the lower part are close to the corresponding two side walls of the lower groove of the guide groove 32.

[0024] Multiple inner baffles 33 are fixed on the inner sidewall of the central through hole 31, and the inner baffles 33 block the inner end of the corresponding guide groove 32.

[0025] One end of the return spring 1 is fixed to the lower part of the guide block 42 facing one end of the inner baffle plate 33, and the other end of the return spring 1 is fixed to the end face of the corresponding inner baffle plate 33. The return spring 1 is inserted into the corresponding guide groove 32.

[0026] Furthermore, a fixed connecting block 50 is fixed on the top surface of the left and right sides of the horizontal rotating plate 30. The fixed connecting block 50 has an adjusting screw connection hole extending to the left and right in the middle. The screw part of the positioning bolt 51 is screwed into the corresponding adjusting screw connection hole. The inner end of the screw part of the positioning bolt 51 extends out of the inner end of the corresponding adjusting screw connection hole and forms a limiting part 52. The limiting part 52 is inserted into the slot formed between the two corresponding heat dissipation fins on the outer side wall of the motor housing 100.

[0027] A spring 53 is inserted into the threaded part of the positioning bolt 51. One end of the spring 53 is applied to the end face of the rotating part of the positioning bolt 51, and the other end is applied to the outer wall of the corresponding fixed connecting block 50.

[0028] In this embodiment, the reset and tensioning action of all the reset springs 1 causes all the sector blocks 40 to come together, pressing the bottom surface of the motor housing 100 to be processed against the top surface of the horizontal rotating plate 30. All the sector blocks 40 are inserted into the lower part of the motor housing 100. Then, the push rod of the lifting cylinder 21 pushes the conical push block 22 to rise, so that the outer wall of the conical push block 22 presses against the corresponding conical wall surface, and all the sector blocks 40 move outward, so that the elastic anti-slip layer 41 presses against the lower inner side wall of the motor housing 100, clamping and fixing it.

[0029] Then, rotate the positioning bolt 51 so that the limiting part 52 is inserted into the slot formed between the two corresponding heat dissipation ribs on the outer side wall of the motor housing 100, thereby achieving further limiting (it is necessary to ensure that the limiting part 52 of the corresponding positioning bolt 51 is aligned with the slot formed between the two corresponding heat dissipation ribs on the outer side wall of the motor housing 100 when the motor housing 100 is placed, so that the subsequent rotation of the positioning bolt 51 will allow the limiting part 52 to be inserted into the slot formed between the two corresponding heat dissipation ribs on the outer side wall of the motor housing 100). Then, the horizontal rotating plate 30 can be rotated to observe and inspect the outer surface of the motor housing 100. Since the rotating block 20 is located in the vertical through hole and is movably connected to the top plate of the fixed frame 10 through the bearing, the resistance during rotation is small, and it can be operated with one hand, which is very convenient.

[0030] In this embodiment, due to the connection pipe of the lower lifting cylinder 21, it rotates in the opposite direction after each clockwise rotation to prevent the connection pipe from getting tangled.

[0031] While rotating, you can hold sandpaper in your other hand and press it against the top surface of the motor housing 100. As the horizontal rotating plate 30 rotates back and forth, you can manually polish the top surface of the motor housing 100. It is easy to operate and has a good polishing effect.

[0032] After completion, the two positioning bolts 51 can be rotated to move the limiting part 52 out of the slot formed between the two corresponding heat dissipation fins on the outer side wall of the motor housing 100. The push rod of the lifting cylinder 21 retracts. At this time, through the reset stretching action of all the reset springs 1, all the sector blocks 40 are brought together, and the motor housing 100 can be disassembled. It is very convenient, easy to process, greatly reduces the amount of manual labor, and has a good effect.

[0033] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
