Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing and repair technology, and in particular to a motor positioning pin removal device. Background Technology

[0002] In the field of modern motor manufacturing and repair, motors with locating pins are widely used. Locating pins play a crucial role in motor assembly, ensuring the precise installation of motor components and guaranteeing motor performance and stability. However, when a motor needs repair, component replacement, or reassembly, removing the locating pins becomes a challenging problem.

[0003] Currently, the industry commonly uses simple tools such as vises and hammers to remove locating pins from motors with locating pins. This traditional method has several serious drawbacks: First, it is extremely inefficient. Since the operation relies mainly on manual hammering or pulling, each removal requires a significant amount of time and effort, which severely restricts production progress in a modern industrial environment that demands high efficiency. Second, it causes secondary damage to the motor shaft. During the hammering or vise removal process, contact and friction with the shaft surface are unavoidable, scratching the shaft surface. This not only affects the appearance quality of the shaft but may also lead to accelerated wear and decreased precision during subsequent use, thus affecting the overall performance and lifespan of the motor, increasing the product defect rate, and raising production costs.

[0004] Furthermore, traditional disassembly methods cannot effectively secure the positioning pins. During the disassembly process, the positioning pins are prone to shaking and shifting, making the disassembly operation more difficult and increasing the risk of damage to surrounding components.

[0005] Meanwhile, the length and installation depth of the locating pins vary between different motor models. Existing disassembly devices, lacking pin height adjustment functionality, are ill-suited to the diverse needs of different motors.

[0006] Therefore, a motor positioning pin removal device is needed. Utility Model Content

[0007] The main objective of this invention is to provide a motor positioning pin retraction device, which can effectively solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A motor positioning pin reversing device includes a base, a placement and fixing mechanism is fixedly connected to the front of the upper end of the base, a slide rod is fixedly connected to the rear side of the upper end of the base, a locking component is slidably connected to the outer surface of the slide rod, and a reversing mechanism is fixedly connected to the front of the outer surface of the locking component.

[0010] Preferably, the placement and fixing mechanism includes a fixing platform, which is fixedly connected to the upper front of the base.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figures 1 to 6 As shown, a motor positioning pin reversing device includes a base 1, a placement and fixing mechanism 2 is fixedly connected to the front of the upper end of the base 1, a slide rod 3 is fixedly connected to the rear side of the upper end of the base 1, a locking component 4 is slidably connected to the outer surface of the slide rod 3, and a reversing mechanism 5 is fixedly connected to the front of the outer surface of the locking component 4.

[0027] In the specific implementation process of this utility model, firstly, the internal structure of the locking assembly 4 is rotated according to the size of the positioning pin, so that the locking assembly 4 slides up and down on the surface of the slide rod 3. Then, the locking assembly 4 drives the reversing mechanism 5 to move up and down to adjust the height. Then, the internal structure of the locking assembly 4 is rotated to fix the locking assembly 4 on the surface of the slide rod 3. Then, the positioning pin that needs to be reversed is placed inside the placement and fixing mechanism 2. After placement, the internal drive structure of the placement and fixing mechanism 2 is activated to drive the internal structure of the placement and fixing mechanism 2 to run, so that the internal structure of the placement and fixing mechanism 2 clamps and fixes the positioning pin placed inside it, ensuring that it will not shake during disassembly. Then, the operator manually shakes the internal structure of the reversing mechanism 5, so that the internal structure of the reversing mechanism 5 descends quickly and squeezes the shaft core inside the positioning pin out to the outside, thereby completing the reversal. Then, the positioning pin can be removed.

[0028] Specifically, in order to achieve the goal of adjusting the height of the anti-dismantling mechanism 5, refer to Figure 4 In this solution, the locking assembly 4 includes a slide tube 42, which is slidably connected to the outer surface of the slide rod 3. A threaded cylinder 43 is fixedly connected to the upper end of the slide tube 42. The outer surface of the threaded cylinder 43 has several openings 44 in an annular shape. A tapered cylinder 41 is threadedly connected to the outer surface of the threaded cylinder 43.

[0029] In the above process, the cone cylinder 41 is rotated by rotating the turntable at the upper end of the cone cylinder 41. As the cone cylinder 41 rotates upward on the surface of the threaded cylinder 43, the bottom of the cone cylinder 41 gradually leaves the surface of the threaded cylinder 43, thereby releasing the threaded cylinder 43 from its restraint. This allows the slide tube 42 and the threaded cylinder 43 to slide up and down on the surface of the slide rod 3 to adjust their height. Then, by rotating the cone cylinder 41 in the opposite direction, the cone cylinder 41 descends on the surface of the threaded cylinder 43. Due to the cone shape of the cone cylinder 41, as the cone cylinder 41 gradually descends on the surface of the threaded cylinder 43, it gradually presses against the surface of the threaded cylinder 43, causing the inner surface of the threaded cylinder 43 to grip the surface of the slide rod 3. This fixes the slide tube 42 on the surface of the slide rod 3, achieving the purpose of height fixation.

[0030] Example 2: In order to achieve the purpose of placing and fixing the positioning pin, refer to... Figure 2 and Figure 3 In this solution, the placement and fixing mechanism 2 includes a fixing platform 21, which is fixedly connected to the front upper part of the base 1. A cylinder 22 is fixedly connected to the front upper part of the fixing platform 21. A sealing tube 23 is fixedly connected to the front middle part of the upper part of the fixing platform 21. A piston disc 24 is slidably connected to the inner cavity of the sealing tube 23. A placement block 25 is fixedly connected to the rear upper part of the fixing platform 21. A groove 26 is provided in the middle upper part of the placement block 25. Clamping mechanisms 27 are fixedly connected to the left and right sides of the outer surface of the placement block 25. A bifurcated tube 28 is fixedly connected to the rear end of the sealing tube 23.

[0031] Furthermore, the output end of the cylinder 22 passes through the front end of the sealing tube 23 and is fixedly connected to the middle of the front end of the piston disc 24.

[0032] In the above process, the positioning pin is first placed in the arc-shaped cavity at the upper end of the placement block 25. Then, the cylinder 22 is activated, causing the output end of the cylinder 22 to push the piston disc 24 to move backward in the inner cavity of the sealing tube 23. This causes the piston disc 24 to push the air pressure in the inner cavity of the sealing tube 23 through the bifurcation tube 28 into the internal structure of the two clamping mechanisms 27. This causes the internal structure of the two clamping mechanisms 27 to move and press and fix the two sides of the positioning pin. Then, the internal structure of the reverse disassembly mechanism 5 is used to reverse disassemble the shaft inside the positioning pin, causing the disassembled shaft to fall into the groove 26.

[0033] Specifically, in order to achieve the purpose of tightening and fixing the locating pin, refer to Figure 2 and Figure 3 In this scheme, the clamping mechanism 27 includes several fixing blocks 272 and two grooves 271. The two grooves 271 are respectively opened on the left and right sides of the upper end of the placement block 25. The several fixing blocks 272 are respectively fixedly connected to the left and right sides of the front end and the left and right sides of the rear end of the placement block 25. The inner surfaces of the several fixing blocks 272 are rotatably connected to arc-shaped clamping blocks 273. The lower parts of the two arc-shaped clamping blocks 273 located on the front side are fixedly connected to piston tubes 274. The inner cavities of the two piston tubes 274 are slidably connected to piston columns 275. The rear ends of the two piston columns 275 extend through the inner wall of the piston tube 274 on the same side to the outside and are rotatably connected to the lower parts of the two arc-shaped clamping blocks 273 on the front side.

[0034] In the above process, air pressure enters the inner cavity of the two piston tubes 274 through the bifurcation pipe 28, causing the air pressure to push the two piston columns 275 to move backward. The piston columns 275 push the arc-shaped clamping block 273 to rotate on the surface of the fixed block 272. At the same time, the piston columns 275 are rotatably connected to the lower part of the arc-shaped clamping block 273 on the rear side, so that the piston columns 275 push the arc-shaped clamping block 273 and cause the two arc-shaped clamping blocks 273 on the same side to rotate relative to each other. In this way, the two arc-shaped clamping blocks 273 flip over to press and fix the positioning pin.

[0035] Specifically, in order to disassemble the locating pin, refer to Figure 5In this scheme, the anti-disassembly mechanism 5 includes a support block 51, which is fixedly connected to the front side of the outer surface of the slide tube 42. A cylinder 52 is fixedly connected to the front end of the support block 51. A gear 53 is rotatably connected to the inner cavity of the cylinder 52. A fixing tube is fixedly connected to the front side of the outer arc of the cylinder 52. A slider 54 is fixedly connected to the front side of the inner arc of the fixing tube. A rack 55 is slidably connected to the rear end of the slider 54. A spring 56 is fixedly connected to the upper end of the rack 55. A pin 57 is fixedly connected to the lower end of the rack 55. The outer surface of the gear 53 is meshed with the rear end of the rack 55.

[0036] In the above process, by shaking the handle on the left side of the cylinder 52 downwards, the gear 53 is driven to rotate. At the same time as the gear 53 rotates, the rack 55 meshing with it rotates downwards on the surface of the slider 54. This causes the rack 55 to drive the ejector pin 57 to descend and squeeze out the shaft core inside the positioning pin. After the squeezing is completed, the hand of the handle is released, and the rack 55 is pulled back to its original position under the action of the spring 56.

[0037] It should be noted that the specific installation method of cylinder 22, the connection method of air circuit, and the control method used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
