Description

Technical Field

[0001] This utility model relates to the field of one-way valve assembly technology, specifically to a one-way valve snap ring assembly device. Background Technology

[0002] A snap ring (also known as a retaining ring, elastic retaining ring, or C-ring) is typically a flexible metal ring-shaped part. It is installed in a groove within a shaft or hole using its elastic deformation. Compressed or expanded by external force or tools, it embeds itself in a predetermined position, serving as an axial limiter and preventing axial movement or detachment of the part within an assembly. As a common mechanical fastener, snap rings are widely used in various fields such as machinery, automobiles, motors, hydraulic systems, and household appliances due to their simple structure and cost-effectiveness.

[0003] In check valves, the snap ring serves as a critical mechanical fixing component, reliably positioning and securing internal components such as the valve core within the valve body. This prevents the snap ring from detaching under high pressure conditions, ensuring reliable valve sealing and stable operation. Currently, the common method for assembling snap rings in check valves involves operators using snap ring pliers to compress the snap ring and insert it into a pre-set groove in the valve body's inner bore. However, manual assembly is slow and inefficient, making it difficult to meet the demands of mass production. Furthermore, variations in the force applied by different operators result in inconsistent assembly precision, affecting assembly quality. Additionally, the snap ring is an elastic component; if tools slip or the snap ring pops out during manual assembly, it can easily cause cuts or flying parts, posing a safety risk.

[0017] like Figures 1 to 6 As shown, a snap ring assembly device for a one-way valve includes a feeding vibratory plate 1, a snap ring feeding post 2, a push plate 3, a push drive device 4, a snap ring clamping device 5, and a snap ring drive device 6. The snap ring feeding post 2 is located at the end of the feeding vibratory plate 1 and the snap ring slides along the snap ring feeding post 2.

The snap ring clamping device 5 is located at the end of the push plate 3 and is used for feeding and clamping the snap ring. The snap ring drive device 6 drives the snap ring clamping device 5 to move in the vertical direction.

[0018] This utility model provides a snap ring assembly device for one-way valves, which realizes automatic feeding, clamping and pressing of snap rings. It has a high degree of automation, reduces manual operation, improves assembly efficiency, and is more suitable for mass production assembly. It ensures the consistency of assembly accuracy and quality, and also reduces the potential safety risks of manual operation.

[0019] It should be noted that the feeding vibratory feeder can be obtained from the prior art, and this application does not involve any improvement to the specific structure of the feeding vibratory feeder.

[0020] Based on the above technical solution, an auxiliary assembly device 7 is also provided below the snap ring clamping device 5. The auxiliary assembly device 7 includes a support plate 71, an auxiliary mounting base 72, and an auxiliary drive assembly 73. The auxiliary mounting base 72 is provided in the receiving hole on the support plate 71. The auxiliary mounting base 72 has a hollow structure inside and an inverted trapezoidal longitudinal section. The support plate 71 is driven by the auxiliary drive assembly 73 to move in the vertical direction.

[0021] Preferably, the bottom opening of the auxiliary mounting base 72 is adapted to the top opening of the valve seat to be assembled.

[0022] By employing an auxiliary assembly device 7 in conjunction with a snap ring clamping device 5, the snap ring can be pre-tightened and assembled. Specifically, the snap ring is placed inside the hollow structure of the auxiliary mounting base 72. Due to its inverted trapezoidal conical sleeve structure, the snap ring gradually tightens as it is conveyed downwards. After being pressed into the valve seat to be assembled, it is then pressed and fixed by the snap ring clamping device 5. This eliminates the need for manual compression with snap ring pliers and placement within the valve body, achieving snap ring pre-tightening, ensuring assembly quality, and reducing safety risks.

[0023] Based on the above technical solution, the snap ring clamping device 5 includes an outer sliding sleeve 51, an inner clamping sleeve 52, and a clamping drive mechanism 53. The outer sliding sleeve 51 is sleeved on the outside of the inner clamping sleeve 52. The inner clamping sleeve 52 is driven by the clamping drive mechanism 53 to slide and connect with the outer sliding sleeve 51. The bottom end of the inner clamping sleeve 52 is provided with elastic clamping pieces 521 spaced apart along the circumferential direction. The bottom end of the outer sliding sleeve 51 is provided with pressure plates 511 spaced apart. The pressure plates 511 and elastic clamping pieces 521 are alternately arranged.

[0024] Specifically, by providing an inner clamping sleeve 52, during the descent of the snap ring clamping device 5, the snap ring is internally clamped within the inner diameter of the snap ring due to the use of elastic clamping plates 521. By providing an outer sliding sleeve 51, it is convenient to unload the snap ring after it reaches the designated position. That is, the outer sliding sleeve remains stationary, the inner clamping sleeve 52 retracts, the pressure plate 511 presses against the snap ring, and the inner clamping sleeve 52 continues to retract to release the clamping of the snap ring and complete the loading.

[0025] Based on the above technical solution, the outer side wall of the elastic clip 521 is provided with a clamping groove 522.

[0026] Preferably, by providing a clamping groove 522 at the bottom of the outer wall of the elastic clip 521, and in conjunction with the elastic properties of the elastic clip 521, the retaining spring is clamped in the clamping groove 521 as the inner clamping sleeve 52 moves downward and approaches the retaining spring, making the clamping more stable.

[0027] Based on the above technical solution, the bottom surfaces of multiple pressure plates 522 are arranged in a spiral shape.

[0028] Preferably, by setting the bottom surfaces of the multiple pressure plates 522 to a spiral shape, i.e., the bottom surfaces of the multiple pressure plates 522 are not on the same horizontal plane, but spiral in the circumferential direction from high to low, the edges of the retaining spring are pressed down sequentially during the pressing process, and the open ring position of the retaining spring is tightened, resulting in a better pressing and closing effect.

[0029] Based on the above technical solution, the push drive device 4, the snap ring drive device 6, and the auxiliary drive component 73 are all configured as cylinders or electric push rods.

[0030] In other preferred embodiments, the push drive device 4, the snap ring drive device 6, and the auxiliary drive assembly 73 can also adopt structures such as linear modules and ball screw pairs, as long as they can drive the linear movement of the push plate, the snap ring clamping device, and the support plate.

[0031] Based on the above technical solution, a limiting sleeve 8 is fixedly provided at the bottom end of the spring clip feeding column 2, and a through hole adapted to the spring clip is provided on the top surface of the limiting sleeve 8, and the push plate 3 slides inside the limiting sleeve 8.

[0032] Preferably, by setting a limiting sleeve 8 and cooperating with the circlip feeding post 2, the circlips are fed; the push plate 3 slides inside it, and the circlips fed to the push plate 3 can be pushed one by one to the bottom end of the circlip clamping device 5, so as to avoid the accumulation of multiple circlips and jamming during the conveying process, and the working efficiency is high.

[0033] Based on the above technical solution, a position detection switch 9 is provided below the snap ring clamping device 5.

[0034] By setting a position detection switch 9, the snap ring conveyed by the push plate 3 to the snap ring clamping device 5 can be detected in time, thereby driving the inner clamping sleeve to clamp the snap ring.

[0035] The snap ring assembly device in this application is used for feeding snap rings and assembling them onto the top of the valve cover inside the valve seat and pressing them tightly. Before assembly, the snap ring is a ring with an opening, and in the initial feeding state, it is located inside the feeding vibratory feeder.

[0036] During feeding: The circlip is conveyed to the circlip feeding column 2 by the feeding vibratory plate 1. The circlip slides down the circlip feeding column 2 into the circlip receiving groove 31 of the push plate 3. Under the action of the push drive device 4, the circlip on the push plate 3 is conveyed to the position of the circlip clamping device 5. Preferably, a position detection switch 9 is provided at this position to detect the circlip that has been conveyed to the position in time and to clamp and feed it in time.

[0037] During clamping: the snap ring drive device 6 drives the snap ring clamping device 5 to move downward to the snap ring position, the clamping drive mechanism 53 drives the inner clamping sleeve 52 to move downward, and the elastic clamping piece 521 passes through the inner diameter of the snap ring and fixes it under the action of elastic force; under the action of the snap ring drive device 6, it is further conveyed downward to the valve seat on the mounting base, at which time the bottom end of the auxiliary mounting base abuts against the top end of the valve seat.

[0038] During assembly, the inner clamping sleeve 52 and its elastic clamping piece 521 move upward under the drive of the clamping drive mechanism 53, while the outer sliding sleeve 51 remains stationary. As the elastic clamping piece 521 moves upward, it pushes the snap ring clamped on the elastic clamping piece 521 into the tapered sleeve with an inverted trapezoidal longitudinal section inside the auxiliary mounting base 72. Then, the inner clamping sleeve 52 moves downward. Under the action of the tapered sleeve and the pressure plate with a spiral arrangement on the bottom end face, the opening of the snap ring gradually narrows and moves downward inside the tapered sleeve, pressing it into the valve seat and onto the top of the valve cover. Then, the inner clamping sleeve 52 moves downward again, further pressing the snap ring to the specified position, thus completing the snap ring loading and assembly process.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments. Therefore, the embodiments should be regarded as exemplary and non-limiting. The scope of this utility model is defined by the appended claims rather than the foregoing description.
