Description

Technical Field

[0001] This utility model relates to the field of hook commutator processing technology, specifically a pressing device for insulation treatment of hook commutators. Background Technology

[0002] A hook commutator is a special type of commutator mainly used in DC motors. Its core function is to ensure the motor can operate continuously and stably during rotation. Through its unique structure and materials, the hook commutator achieves periodic switching of the current direction, thereby ensuring the normal operation of the motor.

[0003] In the insulation process of hook commutators, the clamping and fixing method at both ends is usually used for pressing. However, since the clamps need to be clamped from both ends of the commutator, the clamping mechanism itself will block part of the insulation area to be pressed, which will cause the insulation material in these positions to be insufficiently compacted, affecting the uniformity of the insulation layer. In order to solve the above problems, the inventors have proposed a pressing device for insulation processing of hook commutators. Utility Model Content

[0004] In order to solve the problem that the clamping mechanism itself will block part of the insulation area to be pressed during the insulation treatment of hook commutators, the purpose of this utility model is to provide a pressing device for insulation treatment of hook commutators.

An arc-shaped plate is fixedly provided on one side of the T-shaped block. A guide rod is fixedly provided on one side of the rotating disk. A guide groove is opened in the rotating disk. The guide rod is slidably disposed in the guide groove. A limiting member is fixedly provided on one side of the rotating plate. The limiting member is slidably disposed in the support rod. A limiting groove is opened in the support rod. The limiting member is slidably disposed in the limiting groove. First, the hook-type commutator is placed on the outer surface of the arc-shaped plate. Then, the second motor is turned on, so that the rotating disk rotates and the guide rod slides in the guide groove. Then, the guide rod drives the T-shaped block to slide in the fixed frame. At the same time, the T-shaped block drives the arc-shaped plate to move and approach the inner wall of the commutator, so that the commutator can be internally clamped.

[0006] Then pull the pressure plate, which causes the movable rod to move the movable ring and squeeze the spring. Then the insulating layer is placed on the surface of the second placement plate. Then release the pressure plate, which causes the spring to return to its original position. Then the pressure plate moves down and approaches the top surface of the second placement plate, while pressing the insulating layer. Then the cylinder is activated, which causes the horizontal plate to move the punch down, which in turn causes the insulating layer on the surface of the second placement plate to fall from the through groove opened in the second placement plate and enter the gap between the adjacent commutator segments.

[0007] Then, the first motor is turned on, causing the rotating plate to rotate and driving the disc to rotate, which in turn drives the clamped hook commutator to rotate, pressing the insulating layer between adjacent commutator segments, and then rotating the hook commutator to align the gap between subsequent commutator segments with the bottom end of the punch.

[0008] Preferably, an L-shaped plate is fixedly provided on the top surface of the workbench, a cylinder is installed on the top surface of the L-shaped plate, a horizontal plate is fixedly provided at the output end of the cylinder, and a punch is fixedly provided on the bottom surface of the horizontal plate.

[0009] Preferably, the bottom surface of the L-shaped plate is fixedly provided with an extension plate, a second placement plate is fixedly provided between the extension plates, a first placement plate is fixedly connected between the extension plates, a movable rod is slidably provided in the first placement plate, a pressure plate is fixedly provided at the bottom end of the movable rod, a movable ring is fixedly provided at the top end of the movable rod, the movable ring is slidably provided in the first placement plate, a groove is provided in the first placement plate, the movable ring is slidably provided in the groove, and a spring is fixedly connected between the inner wall of the groove and the movable ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The T-shaped block drives the arc plate to move and approach the inner wall of the commutator, thereby clamping the commutator internally, avoiding obstruction of the insulation area of ​​the commutator, and allowing the insulation material to be fully compacted without affecting the uniformity of the insulation layer.

[0012] 2. By placing the insulating layer on the surface of the second placement plate, and then moving the pressure plate down and close to the top surface of the second placement plate, while pressing the insulating layer, the insulating layer can be accurately positioned directly above the gap between adjacent commutator segments. Then, at the moment the punch contacts the insulating layer, the insulating layer shifts, thereby ensuring that the insulating layer is uniformly positioned in the gap between adjacent commutator segments.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1-7As shown, this utility model provides a pressing device for insulation treatment of a hook-type commutator, including a workbench 1. A mounting plate 2 is fixedly mounted on the top surface of the workbench 1. A support rod 21 is fixedly mounted on the top surface of the mounting plate 2. A first motor 22 is mounted on one side of the support rod 21. A rotating plate 23 is fixedly mounted at the output end of the first motor 22. A connecting rod 25 is fixedly mounted on one side of the rotating plate 23. A disc 31 is fixedly mounted on one side of the connecting rod 25. A second motor 3 is mounted on one side of the disc 31. A rotating disk 32 is fixedly mounted at the output end of the second motor 3. A fixing frame 33 is fixedly mounted on the outer surface of the disc 31. A T-shaped block 34 is slidably mounted inside the fixing frame 33. An arc-shaped plate 36 is fixedly mounted on one side of the T-shaped block 34. A guide rod 35 is fixedly mounted on one side of the T-shaped block 34. A guide groove 321 is opened inside the rotating disk 32. The guide rod 35 is slidably mounted in the guide groove 321. A limiting member 24 is fixedly mounted on one side of the rotating plate 23. The limiting member 24 is slidably mounted in the... Inside the support rod 21, a limiting groove 211 is provided. The limiting member 24 is slidably disposed in the limiting groove 211. By placing the hook-type commutator on the outer surface of the arc plate 36, and then turning on the second motor 3, the rotating disk 32 is rotated, and the guide rod 35 slides in the guide groove 321. The guide rod 35 then drives the T-shaped block 34 to slide in the fixed frame 33. At the same time, the T-shaped block 34 drives the arc plate 36 to move and approach the inner wall of the commutator, thereby clamping the commutator internally and avoiding obstruction of the insulation area of ​​the commutator. This allows the insulation material to be fully compacted without affecting the uniformity of the insulation layer. By turning on the first motor 22, the rotating plate 23 is rotated, which drives the disk 31 to rotate. This causes the clamped hook-type commutator to rotate, pressing the insulation layer between adjacent commutator segments. After rotating the hook-type commutator, the gap between the subsequent commutator segments is aligned with the bottom end of the punch 43.

[0024] An L-shaped plate 4 is fixedly provided on the top surface of the workbench 1. A cylinder 41 is installed on the top surface of the L-shaped plate 4. A horizontal plate 42 is fixedly provided at the output end of the cylinder 41. A punch 43 is fixedly provided on the bottom surface of the horizontal plate 42.

[0025] By adopting the above technical solution, by opening the cylinder 41, the horizontal plate 42 drives the punch 43 to descend, thereby driving the insulating layer on the surface of the second placement plate 51 to fall from the through groove opened in the second placement plate 51 and enter the gap between adjacent commutator segments.

[0026] An extension plate 5 is fixedly provided on the bottom surface of the L-shaped plate 4. A second placement plate 51 is fixedly provided between the extension plates 5. A first placement plate 44 is fixedly connected between the extension plates 5. A movable rod 48 is slidably provided in the first placement plate 44. A pressure plate 49 is fixedly provided at the bottom end of the movable rod 48. A movable ring 46 is fixedly provided at the top end of the movable rod 48. The movable ring 46 is slidably provided in the first placement plate 44. A groove 45 is provided in the first placement plate 44. The movable ring 46 is slidably provided in the groove 45. A spring 47 is fixedly connected between the inner wall of the groove 45 and the movable ring 46.

[0027] By adopting the above technical solution, by pulling the pressure plate 49, the movable rod 48 moves the movable ring 46 and squeezes the spring 47. Then, the insulating layer (the insulating layer is a mica sheet) is placed on the surface of the second placement plate 51 and the insulating layer is located in the middle of the second placement plate 51. Then, the pressure plate 49 is released, so that the spring 47 is reset, and the pressure plate 49 moves down and approaches the top surface of the second placement plate 51, while pressing the insulating layer. At this time, the insulating layer can be accurately positioned directly above the gap between adjacent commutator segments. Then, at the moment the punch 43 contacts the insulating layer, the insulating layer shifts, thereby ensuring that the insulating layer is evenly positioned in the gap between adjacent commutator segments.

[0028] Working principle: First, place the hook-type commutator on the outer surface of the arc plate 36, then turn on the second motor 3, so that the rotating disk 32 rotates and the guide rod 35 slides in the guide groove 321, which in turn causes the guide rod 35 to drive the T-shaped block 34 to slide in the fixed frame 33. At the same time, the T-shaped block 34 drives the arc plate 36 to move and approach the inner wall of the commutator, thus enabling the commutator to be internally clamped.

[0029] Then, pull the pressure plate 49, which causes the movable rod 48 to move the movable ring 46 and squeeze the spring 47. Then, place the insulating layer on the surface of the second placement plate 51 and position the insulating layer in the middle of the second placement plate 51. Then, release the pressure plate 49, which causes the spring 47 to return to its original position. Then, the pressure plate 49 moves down and approaches the top surface of the second placement plate 51, while pressing the insulating layer. At this time, the insulating layer can be accurately positioned directly above the gap between adjacent commutator segments. Then, at the moment the punch 43 contacts the insulating layer, the insulating layer shifts, thus ensuring that the insulating layer is evenly positioned in the gap between adjacent commutator segments. Then, open the cylinder 41, which causes the horizontal plate 42 to drive the punch 43 down, which in turn causes the insulating layer on the surface of the second placement plate 51 to fall from the through groove opened in the second placement plate 51 and enter the gap between adjacent commutator segments.

[0030] Then, the first motor 22 is turned on, which causes the rotating plate 23 to rotate and drives the disc 31 to rotate. This, in turn, drives the hook-type commutator after clamping to rotate, so that the insulating layer is pressed between the gaps of adjacent commutator segments. Then, the hook-type commutator is rotated to align the gaps between subsequent commutator segments with the bottom end of the punch 43.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
