Abstract
Description
Technical Field
[0001] This utility model relates to the field of snap ring assembly technology, and in particular to a snap ring assembly mechanism. Background Technology
[0002] During product assembly, it is often necessary to install retaining rings onto retaining posts of the product frame. The retaining ring has a C-shaped cross-section with openings on its periphery, while the retaining post is circular with mounting slots on its periphery. When assembling the retaining ring and retaining post, the operator typically inserts the two jaws of a retaining ring pliers into the mounting holes at both ends of the retaining ring, then tightens the handles. This enlarges the opening of the retaining ring. The retaining ring is then placed onto the retaining post, aligned with the mounting slot, and the handles are released. The retaining ring retracts and returns to its original position due to its elasticity, fitting into the mounting slot and onto the retaining post. Repeatedly installing retaining rings requires constant gripping and releasing of the pliers, which can easily cause finger fatigue. Utility Model Content

[0023] During product assembly, it is often necessary to install retaining rings onto retaining posts of the product frame. The retaining ring has a C-shaped cross-section with openings on its periphery, while the retaining post is circular with mounting grooves on its periphery. When assembling the retaining ring and retaining post, the operator typically inserts the two jaws of a retaining ring pliers into the mounting holes at both ends of the retaining ring, then tightens the handles. This widens the opening of the retaining ring. The retaining ring is then placed onto the retaining post, aligned with the mounting groove, and the handles are released. The retaining ring retracts and returns to its original position due to its elasticity, fitting into the mounting groove and onto the retaining post. Repeatedly installing retaining rings requires constant gripping and releasing of the pliers, which can easily cause finger fatigue and increase the operator's workload.
[0024] This utility model proposes a retaining ring assembly mechanism.
[0025] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, the retaining ring assembly mechanism is used to assemble a retaining ring 8 and a product rack 7 with a retaining post 71. The retaining ring assembly mechanism includes: a base 1, a support 2, a pressure seat 3, and a pusher 4. The support 2 is disposed on the base 1 and is used to support the product rack 7, so that the retaining post 71 is vertically arranged. The pressure seat 3 is movably disposed on the base 1 in the vertical direction and is located above the support 2. The pressure seat 3 is used to press the product rack 7. The pusher 4 is movably disposed on the base 1 in the first horizontal direction and has a pusher end 41. The support 2 is located on the moving path of the pusher end 41. The pusher end 41 is used to push the retaining ring 8 so that when the opening of the retaining ring 8 abuts against the retaining post 71, the opening of the retaining ring 8 is expanded and it is sleeved on the retaining post 71 from the periphery of the retaining post 71.
[0026] In this invention, after placing the product rack 7 on the support 2, the locking post 71 is kept vertical. Then, the pressure seat 3 is lowered vertically, pressing down on the upper side of the product rack 7 to secure it and limit the locking post 71. Finally, the opening of the retaining ring 8 is aligned with the locking post 71, and the pusher 4 is moved horizontally. The pusher 4 pushes the retaining ring 8 so that its opening abuts against the locking post 71. As the pusher 4 continues to move, the opening of the retaining ring 8 expands and fits onto the locking post 71. When the retaining ring 8 is fitted onto the locking post 71, its opening contracts and decreases. This design avoids manual gripping and releasing of the retaining ring 8, reducing finger fatigue and improving the problem of finger fatigue during long-term assembly.
[0027] Please see Figure 2 , Figure 3 and Figure 4 The product rack 7 is C-shaped, and the retaining post 71 is located on the inner side of the product rack 7. The retaining post 71 can be fixedly connected or rotatably connected to the product rack, which is not limited here. The retaining post 71 is cylindrical, and an assembly groove is provided on the periphery of the retaining post 71. The assembly groove is an annular groove used to accommodate the retaining ring 8. After the retaining ring 8 is sleeved on the retaining post 71, the retaining ring 8 is located in the assembly groove. After the product rack 7 is placed on the support 2, the opening of the product rack 7 faces the same direction, and the retaining post 71 is vertically arranged to minimize the cross-sectional size of the retaining post 71 in the horizontal direction and reduce the deformation of the retaining ring 8 when it is sleeved on the retaining post 71.
[0028] The retaining ring 8 is C-shaped, with an arc greater than 180°, and the inner radius of the retaining ring 8 is greater than the radius of the retaining post 71. The opening of the retaining ring 8 is smaller than the diameter of the retaining post 71. When the retaining ring 8 is fitted onto the retaining post 71, the opening of the retaining ring 8 abuts against the circumference of the retaining post 71. Under the action of the retaining post 71, the opening of the retaining ring 8 can increase to facilitate the fitting of the retaining ring 8 onto the retaining post 71.
[0029] Please see Figure 2 , Figure 3 and Figure 5 The pushing end 41 of the pushing member 4 has two ends 411 arranged in parallel along the second horizontal direction. The two ends 411 can move closer to each other and further away from each other along the second direction. The two ends 411 are arranged together to form a retaining groove 412. The retaining groove 412 is arranged laterally through to form an inlet for guiding the retaining post 71 into the retaining ring 8 located in the retaining groove 412.
[0030] When the retaining ring 8 is engaged within the two ends 411, the two ends 411 can move away from each other, thereby increasing the size of the retaining groove 412. This facilitates the placement of the retaining ring 8 within the retaining groove 412. The two ends 411 also move closer together, securing the retaining ring 8 within the retaining groove 412, allowing the retaining ring 8 to be pre-installed on the pushing end. When the retaining ring 8 abuts against the retaining post 71, the opening of the retaining ring 8 increases. Furthermore, when the retaining ring 8 deforms, the two ends 411 can move away from each other, providing deformation space for the retaining ring 8 and reducing interference with its deformation while ensuring proper pushing. After the retaining ring 8 is fitted onto the retaining post 71, moving the pushing member away from the retaining post 71 allows the two ends 411 to move closer together, ensuring the clamping and fixing of the next retaining ring 8.
[0031] The two ends 411 can be metal structural components, and the two ends 411 can be detachably or integrally connected to the body of the pusher, which is not limited here. The first horizontal direction and the second horizontal direction are perpendicular to each other.
[0032] The inner wall of the retaining groove 412 is provided with a limiting flange 413, the lower end of which abuts against the upper end of the retaining ring 8. The limiting flange 413 can limit the retaining ring 8 held in the retaining groove 412. Specifically, the upper side of the retaining ring 8 abuts against the limiting flange 413 to prevent the retaining ring 8 from tilting.
[0033] The lower side of the limiting protrusion 413 is at the same height and is a plane. The limiting protrusion 413 can be set at intervals or continuously along the arc of the holding groove 412, which is not limited here.
[0034] Please see Figure 1 , Figure 2 and Figure 3 At least one of the pressure seat 3 and the pusher 4 is configured as an actuating part; the retaining ring assembly mechanism includes a drive structure 5, which includes a clamping seat 51, a quick clamp 52, a connecting arm 53, and a drive rod 54. The clamping seat 51 is fixedly connected to the base 1; the quick clamp 52 has a first hinged mounting part 521 and a second hinged mounting part 522 spaced apart; one end of the connecting arm 53 is connected to the second hinged mounting part 522, and the other end of the connecting arm 53 is hinged to the clamping seat 51; one end of the drive rod 54 is connected to the first hinged mounting part 521, and the other end of the drive rod 54 is connected to the actuating part.
[0035] By moving the quick-release clamp 52, the connecting arm 53 can be rotated, thereby moving the drive rod 54 and locking it. Reversing the rotation of the connecting arm 53 causes the drive rod 54 to move in the opposite direction, thus driving the actuating part. The operator can drive and lock the actuating part by holding and rotating the connecting arm 53.
[0036] The clamping seat 51 can be fixedly mounted on the base 1 by bolts, and the clamping seat 51 is located on the upper side of the pressure seat 3. Both the first hinge mounting part 521 and the second hinge mounting part 522 can be hinge holes. The drive rod 54 and the connecting arm 53 are rotatably mounted on the quick clamp 52 through a hinge shaft and hinge holes. The drive rod 54, the first hinge mounting part 521, and the second hinge mounting part 522 are arranged sequentially. The connection between the drive rod 54 and the actuating part can be any feasible fixed connection structure.
[0037] Both the pressure seat 3 and the pusher 4 are configured as actuating parts. Two drive structures 5 are provided, corresponding to and connected to the two actuating parts, enabling the lifting and lowering of the pressure seat 3 and maintaining its pressure on the product rack 7. This achieves control over the movement of the pusher 4. The pressure seat 3 and the pusher 4 can also be controlled by existing automatic pushing devices, such as electric push rods; this is not limited here.
[0038] The clamping seat 51 corresponding to the pressure seat 3 is a first clamping seat 511. The base 1 includes a seat body and a slide seat 11 that is slidably mounted relative to the seat body in the vertical direction. The drive rod 54 is connected to the slide seat 11. By setting the slide seat 11, the vertical movement of the first clamping seat 511 can be guided.
[0039] Specifically, the base 1 is provided with a guide rail 13 arranged in the vertical direction, and the slide 11 is slidably mounted on the guide rail 13, thereby realizing the guidance for the lifting and lowering of the slide 11.
[0040] The base body is provided with a limiting part 12 to limit the movement of the slide block 11. After the slide block 11 moves down and reaches a certain height, the slide block 11 can abut against the limiting part 12, thereby limiting the movement of the slide block 11. The limiting part 12 can be a limiting part 12 fixedly installed on the base 1. Specifically, the limiting part 12 is a limiting bolt threaded onto the base 1. The limiting bolt is vertically installed, and the limiting position of the slide block 11 can be adjusted by rotating the limiting bolt.
[0041] A first guide seat 14 is provided on the upper side of the base 1, and a guide groove 141 is provided on the first guide seat 14. The pusher 4 is slidably limited within the guide groove 141. By providing the guide groove 141, the pusher 4 is limited, the offset of the pusher 4 is reduced, and the accurate pushing of the limiting member onto the retaining ring 8 is ensured. The guide groove 141 can be formed by opening it in the first guide seat 14, or the guide groove 141 can be cast into the first guide seat 14, and no limitation is made here.
[0042] Please see Figure 1 , Figure 2 and Figure 6 The retaining ring assembly mechanism further includes a second guide seat 6, which is connected to the pressure seat 3. The second guide seat 6 has a guide hole 61 extending along a first horizontal direction. The opening end of the guide hole 61 is flared to allow the retaining ring 8 and the pushing end to pass through. The guide hole 61 helps to limit the positioning of the pushing member 4 and the retaining ring 8, reducing their offset and ensuring accurate pushing of the retaining ring 8 by the limiting member.
[0043] The second guide seat 6 is fixedly connected to the pressure seat 3. When the pressure seat 3 moves upward, the second guide seat 6 can move upward with the pressure seat 3, reducing the interference of the second guide seat 6 on the placement of the product rack 7. The second guide seat 6 is located on the side of the product rack 7 closest to the first guide seat 14.
[0044] The guide hole 61 is flared to facilitate the insertion of the push end 41 into the guide hole 61. The lower sidewall of the guide hole 61 is horizontal to ensure that the lower sidewall of the guide hole 61 supports the retaining ring 8.
[0045] Please see Figure 1 , Figure 5 and Figure 6 The lower side of the pressure base 3 has at least two pressure heads 31, which are used to press the product rack 7. A first clearance groove 32 is formed between the at least two pressure heads 31, which is used to avoid the locking post 71 on the product rack 7. By setting at least two pressure heads 31, the product rack 7 can be pressed against the periphery of the locking post 71, ensuring the fixing effect of the locking post 71. There can be two, three or more pressure heads 31, which is not limited here. Specifically, there are two pressure heads 31. Two pressure grooves are set on the inner sidewall of the product rack 7 on opposite sides of the locking post 71. The two pressure heads 31 can be inserted into the two locking grooves 72, ensuring the pressing effect of the pressure heads 31 on the product rack 7.
[0046] The support 2 has a limiting protrusion 21 on its upper side, which abuts against the side of the product frame 7 away from the pusher 4. When the retaining ring 8 is fitted onto the retaining post 71, the limiting protrusion 21 limits the movement of the product frame 7, thereby reducing the movement of the retaining post 71 and ensuring the assembly of the retaining ring 8 and the retaining post 71. The limiting protrusion 21 can be integrally installed on the support 2 or fixedly installed by bolts, which is not limited here.
[0047] The support 2 is provided with a second clearance groove 22, which is used to avoid the protrusion 73 located on the lower side of the product rack 7. By providing the second clearance groove 22, the product rack 7 can be placed more stably on the support 2. The second clearance groove 22 has an opening on the side near the pusher 4, which facilitates the insertion of the protrusion 73 on the lower side of the product rack 7 into the second clearance groove 22 from the side, making it easier to install the product rack 7.
[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
