Description

Technical Field

[0001] This invention relates to a clamping mechanism, and more particularly to a snap ring clamping assembly mechanism. Background Technology

[0002] In the new energy vehicle industry, shock absorbers require the assembly of retaining rings during production. Retaining rings are made of rigid material with high hardness; if the clamping mechanism is poorly designed, it is difficult to assemble them properly. During pressing, if the pressure head lifts, the retaining ring may not be fully pressed in or may be ejected. This results in the product being deemed unqualified on the automated production line, requiring rework or scrapping, causing significant economic losses.

[0003] Currently, most snap ring clamping methods involve a drive mechanism directly pressing the snap ring into the snap ring groove. Specifically, the snap ring is first placed above the snap ring groove by grippers, and then the drive mechanism moves downward to press the snap ring into the groove. However, because there is no positioning or correction process after placing the snap ring, problems such as misalignment or tilting between the snap ring and the snap ring groove can occur, preventing the snap ring from being fully pressed into the groove and resulting in product defects. For example, CN212577989U, a snap ring assembly mechanism and snap ring assembly equipment, directly presses the snap ring into the snap ring groove by a drive mechanism, which suffers from the aforementioned problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The technical problem to be solved by this invention is: how to solve the problem that the current method of directly pressing the retaining ring into the retaining ring groove by the drive mechanism is prone to the retaining ring not being pressed in properly or popping up, resulting in unqualified assembly, and rework causes low efficiency and large losses.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] The sealing cover retaining spring clamping assembly mechanism includes a retaining spring fixing seat, a clamping guide sleeve, a drive shaft, and a slider that can move along the central axis of the retaining spring. The bottom of the retaining spring fixing seat is the retaining spring sleeve connection point. The retaining spring fixing seat and the clamping guide sleeve are slidably connected coaxially. The slider moves through the retaining spring fixing seat and the clamping guide sleeve. The clamping guide sleeve includes a horizontally penetrating drive shaft hole. The slider includes an inclined elongated hole. The drive shaft is fixedly connected to the drive shaft hole and passes through the inclined elongated hole.

[0008] The working process of this invention involves placing the retaining circumferential ring above the retaining circumferential groove using grippers. The retaining circumferential fixing seat then moves vertically downwards, with its bottom retaining circumferential sleeve securing the ring. The slider then moves horizontally, and the drive shaft of the inclined elongated hole on the slider, along with the clamping guide sleeve fixedly connected to it, moves downwards. Under the horizontal driving force of the slider, the inclined surface of the elongated hole converts the horizontal driving force into a vertically downward driving force. This vertically downward driving force drives the clamping guide sleeve downwards, pressing the retaining circumferential ring down, thus detaching it from the retaining circumferential fixing seat and inserting it into the retaining circumferential groove. This invention corrects the position of the retaining circumferential ring by using the retaining circumferential fixing seat, arranging and maintaining it coaxially with the retaining circumferential groove. The horizontal driving force is then converted into a vertically downward force to detach the retaining circumferential ring from the retaining circumferential fixing seat. This ensures that the retaining circumferential ring always corresponds to the position of the retaining circumferential groove during insertion, guaranteeing accurate insertion. This invention has a simple and reasonable structure, facilitating manufacturing, assembly, adjustment, inspection, and maintenance. It reduces the defect rate, significantly improves production cycle time, and offers stable performance.

[0009] Preferably, the retaining ring fixing seat includes a horizontally penetrating vertical elongated hole, and the drive shaft passes through the vertical elongated hole and the inclined elongated hole after being fixedly connected to the drive shaft hole.

[0010] To ensure the coaxiality of the snap ring holder and the clamping guide sleeve, the gap between them is very small. Also, to facilitate the installation of the drive shaft and slider, a vertical elongated hole is made in the snap ring holder. This makes it easy to install the drive shaft, clamping guide sleeve, and slider, and also allows the vertical elongated hole to avoid obstructing the drive shaft during the pressing process.

[0011] Preferably, the retaining ring holder includes a through first rectangular groove, the snapping guide includes a second rectangular groove, the first rectangular groove and the second rectangular groove are aligned, and the slider passes through the first rectangular groove and the second rectangular groove.

[0012] Preferably, it further includes a horizontal drive mechanism, which includes a connecting bracket and a pressing cylinder. One end of the connecting bracket is connected to the top of the snap ring fixing seat, and the pressing cylinder is horizontally connected to the other end of the connecting bracket.

[0013] Preferably, it further includes a vertical drive mechanism, the telescopic end of which is connected to the top of the snap ring fixing seat.

[0014] Preferably, the first rectangular groove and the second rectangular groove are symmetrical along the vertical through-center axis of the snap ring fixing seat.

[0015] The first rectangular groove and the second rectangular groove are symmetrically located on the central axis of the snap ring holder, so that the slider is also located on the central axis of the snap ring holder. This ensures that the vertical driving force is in the middle position, maintains the uniformity of the downward driving force, and further improves the stability of the downward pressure.

[0016] Preferably, the retaining ring fixing seat includes a fixing block and a sleeve shaft, the sleeve shaft is connected to the bottom of the fixing block, the clamping guide sleeve is a sleeve structure with a larger upper end and a smaller lower end, and the sleeve shaft is sleeved inside the clamping guide sleeve.

[0017] Preferably, the length of the sleeve shaft is greater than the length of the clamping guide sleeve.

[0018] Ensure that the sleeve shaft can extend out from the bottom of the snap-fit ​​guide sleeve and can fit the snap ring.

[0019] Preferably, the outer diameter of the bottom of the sleeve shaft is equal to the inner diameter of the retaining ring, and the outer diameter of the snapping guide sleeve is equal to or greater than the outer diameter of the retaining ring.

[0020] Preferably, the projected height of the inclined elongated hole in the vertical direction is equal to or greater than the sum of the height of the retaining ring and the depth to which the retaining ring is pressed into place.

[0021] The vertical projection height of the inclined elongated hole is equal to or greater than the sum of the height of the retaining ring and the depth to which the retaining ring is pressed into place, ensuring that the retaining ring is pressed completely and stably into the retaining ring groove.

[0022] The advantages of this invention are:

[0023] (1) In the working process of this invention, after the snap ring is placed above the snap ring groove by the gripper, the snap ring fixing seat moves vertically downward, and the snap ring sleeve at its bottom fits the snap ring. Then the slider moves horizontally, and the drive shaft of the inclined elongated hole on the slider and the pressing guide sleeve fixedly connected to it move downward. That is, under the action of the horizontal driving force of the slider, the inclined surface of the inclined elongated hole converts the horizontal driving force into a vertically downward driving force. The vertically downward driving force drives the pressing guide sleeve downward, thus pressing down the snap ring, realizing the snap ring detachment from the snap ring fixing seat and snapping into the snap ring groove. This invention corrects the position of the snap ring by using the snap ring fixing seat, arranging it coaxially with the snap ring groove and keeping it there. Then, the horizontal driving force is converted into a vertically downward force to detach the snap ring from the snap ring fixing seat, so that the snap ring always corresponds to the position of the snap ring groove during the snap ring groove snapping process, thereby ensuring that the snap ring is accurately pressed into the snap ring groove. This invention has a simple and reasonable structure, which is convenient for manufacturing, assembly, adjustment, inspection, maintenance, etc.; it reduces the defect rate and greatly improves the production cycle; and its performance is stable.

[0024] (2) Based on the consideration of ensuring the coaxiality of the snap ring fixing seat and the snapping guide sleeve, the gap between the two is very small, and the consideration of facilitating the installation of the drive shaft and the slider, a vertical elongated hole is opened on the snap ring fixing seat to facilitate the installation of the drive shaft, the snapping guide sleeve and the slider, and to allow the vertical elongated hole to avoid the drive shaft during the pressing process of the snapping guide sleeve and the drive shaft.

[0025] (3) The first rectangular groove and the second rectangular groove are symmetrically located on the central axis of the snap ring fixing seat, so that the slider is also located on the central axis of the snap ring fixing seat, so that the vertical driving force is located in the middle position, maintaining the uniformity of the downward driving force and further improving the stability of the downward pressure.

[0026] (4) The length of the sleeve shaft is greater than the length of the clamping guide sleeve, so that the sleeve shaft can extend out of the bottom of the clamping guide sleeve and can fit the snap ring.

[0027] (5) The vertical projection height of the inclined elongated hole is equal to or greater than the sum of the height of the snap ring and the depth of the snap ring pressed into place, so as to ensure that the snap ring is pressed into the snap ring groove completely and stably.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] like Figure 1 , Figure 2 , Figure 3 As shown, the sealing cover retaining spring clamping assembly mechanism includes a retaining spring fixing seat 1, a clamping guide sleeve 2, a drive shaft 3, and a slider 4, which can move along the central axis of the retaining spring. The bottom of the retaining spring fixing seat 1 is the retaining spring sleeve connection point. The retaining spring fixing seat 1 and the clamping guide sleeve 2 are coaxially and slidably connected. The slider 4 moves through the retaining spring fixing seat 1 and the clamping guide sleeve 2. The clamping guide sleeve 2 includes a horizontally penetrating drive shaft hole 22. The slider 4 includes an inclined elongated hole 41. The drive shaft 3 is fixedly connected to the drive shaft hole 22 and passes through the inclined elongated hole 41.

[0043] Specifically, in combination Figure 1 , Figure 2 As shown, the retaining ring holder 1 includes an integrally formed fixing block and a sleeve shaft. The sleeve shaft is connected to the bottom of the fixing block. The fixing block can be a square block, an oblong block, etc., and the sleeve shaft is a cylindrical shaft. The top of the fixing block is connected to a vertical drive mechanism. When the vertical drive mechanism is activated, its extension end provides a vertical square driving force to the retaining ring holder 1. In this embodiment, the vertical drive mechanism can be a cylinder. To ensure that the driving force is realized vertically downward and to improve the coaxiality of the retaining ring 6 and the retaining ring groove, the central axis of the fixing block, the central axis of the sleeve shaft, the central axis of the vertical drive mechanism, and the central axis of the retaining ring groove are coincident. This can be achieved during the debugging before pressing the retaining ring 6.

[0044] A first rectangular groove 11 is formed through the sleeve shaft of the snap ring fixing seat 1. The first rectangular groove 11 is symmetrically located on the central axial surface of the snap ring fixing seat 1. The first rectangular groove 11 is for the slider 4 to pass through. Since the slider 4 has a rectangular cross-section in this embodiment, the first rectangular groove 11 is larger than the vertical cross-section of the slider 4. Of course, the first rectangular groove 11 can also be adapted to the shape of the slider 4. For example, if the cross-section of the slider 4 is square, the first rectangular groove 11 can be square. A through vertical elongated hole 12 is also formed through the sleeve shaft of the snap ring fixing seat 1. Specifically, the vertical elongated hole 12 is an oblong hole. In this embodiment, the angle between the plane of symmetry of the first rectangular groove 11 and the vertical elongated hole 12 can be 90 degrees.

[0045] The bottom of the sleeve shaft is equal to or slightly smaller than the inner diameter of the retaining ring 6, allowing the sleeve shaft to fit into the retaining ring. The bottom edge of the sleeve shaft is chamfered to provide a guiding effect, helping the retaining ring 6 to smoothly engage with the bottom of the sleeve shaft. This ensures that the retaining ring 6 is fitted onto the outer diameter of the sleeve shaft, in a horizontal and non-eccentric position.

[0046] Combination Figure 1 , Figure 3 As shown, the clamping guide sleeve 2 is a sleeve structure with a larger upper end and a smaller lower end. The connecting shaft is sleeved inside the clamping guide sleeve 2, meaning the connecting shaft can move up and down along the axial direction of the clamping guide sleeve 2. The larger upper portion and the smaller lower portion are connected by a conical surface. A second rectangular groove 21 is formed through the larger upper portion. The first rectangular groove 11 and the second rectangular groove 21 are aligned, and the slider 4 can pass through both the first rectangular groove 11 and the second rectangular groove 21. The clamping guide sleeve 2 also has a drive shaft hole 22. The angle between the drive shaft hole 22 and the plane of symmetry of the second rectangular groove 21 is also 90 degrees. The position of the drive shaft hole 22 corresponds to the vertical elongated hole 12.

[0047] In this embodiment, the length of the sleeve shaft is greater than the length of the clamping guide sleeve 2, so as to ensure that the sleeve shaft can extend out of the bottom of the clamping guide sleeve 2 and can fit the snap ring 6.

[0048] The outer diameter of the clamping guide sleeve 2 is equal to or greater than the outer diameter of the retaining spring 6. This ensures that the bottom surface of the clamping guide sleeve 2 can effectively apply force to the top of the retaining spring 6.

[0049] The first rectangular groove 11 and the second rectangular groove 21 are symmetrically located on the central axis of the snap ring holder 1, so that the slider 4 is also located on the central axis of the snap ring holder 1, so that the vertical driving force is located in the middle position, maintaining the uniformity of the downward driving force and further improving the stability of the downward pressure.

[0050] like Figure 1 , Figure 4 , Figure 5As shown, slider 4 is a rectangular strip plate with a horizontally penetrating inclined elongated hole 41 in its middle. The inclined elongated hole 41 is positioned with its left end higher than its right end. It is located inside the larger upper part of the clamping guide sleeve 2. The inclined elongated hole 41 is an oblong hole with an inclination angle of α and a length L. Therefore, its vertical height H1 = L * sinα. The vertical projection height L of the inclined elongated hole 41 is equal to or greater than the sum of the height of the retaining spring and the depth to which the retaining spring is pressed into place, thus ensuring that the retaining spring 6 is completely and stably pressed into the retaining spring groove. It should be noted that the inclined elongated hole 41 can be inclined with the left end higher or the right end higher.

[0051] Therefore, after the drive shaft 3 is inserted into the drive shaft hole 22 and fixed thereto by welding, pins, or other means, the structure is stable. Both ends of the drive shaft 3 can be accommodated in the vertical elongated hole 12, and because the slider 4 passes through the first rectangular groove 11 and the second rectangular groove 21, the part of the drive shaft 3 located inside the clamping guide sleeve 2 also passes through the inclined elongated hole 41 of the slider 4.

[0052] The drive shaft 3 can be a uniform cylindrical shaft, and the inclined elongated hole 41 is an oblong hole. The connection between the drive shaft 3 and the inclined elongated hole 41 is equal to or slightly smaller than the diameter of the oblong hole, ensuring that the drive shaft 3 can slide within the inclined elongated hole 41. The drive shaft 3 can also be a cylindrical shaft with a variable diameter, but the connection between the drive shaft 3 and the inclined elongated hole 41 is still equal to or slightly smaller than the diameter of the oblong hole. The diameter at the connection between the drive shaft 3 and the drive shaft hole 22 can be set slightly larger.

[0053] To ensure the coaxiality of the snap ring holder 1 and the clamping guide sleeve 2, the gap between them is very small. Therefore, if the drive shaft 3 extends outside the clamping guide sleeve 2, it is easy to interfere with the outer surface of the snap ring holder 1. Furthermore, in this embodiment, since the drive shaft 3 passes through both the inclined elongated hole 41 and the drive shaft hole 22, and the slider 4 is located inside the clamping guide sleeve 2, ease of installation needs to be considered. Therefore, a vertical elongated hole 12 is provided on the snap ring holder 1 to facilitate the installation of the drive shaft 3 with the clamping guide sleeve 2 and the slider 4, and to allow the vertical elongated hole 12 to avoid obstructing the drive shaft during the pressing process of the clamping guide sleeve 2 and the drive shaft 3.

[0054] The specific installation process can be as follows: Insert the clamping guide sleeve 2 from the bottom of the snap ring fixing seat 1 into the first rectangular groove 11 and the second rectangular groove 21, at which point the drive shaft hole 22 is also aligned with the vertical elongated hole 12. Pass the slider 4 through the first rectangular groove 11 and the second rectangular groove 21, aligning the inclined elongated hole 41 with the drive shaft hole 22 and the vertical elongated hole 12. Then, pass the drive shaft through the vertical elongated hole 12, the drive shaft hole 22, and the inclined elongated hole 41, and fix the drive shaft 3 to the drive shaft hole 22 using screws or other means. At this point, the drive shaft 3 and the clamping guide sleeve 2 are fixed together, so the movement of the drive shaft 3 can drive the movement of the clamping guide sleeve 2.

[0055] The working process of this embodiment,

[0056] refer to Figure 4 As shown, in the initial state, the vertical drive mechanism is in the original position, and the snap ring fixing seat 1 is in the original position vertically upward; at this time, the highest point (left end) of the inclined elongated hole 41 contacts the drive shaft 3, so that the snapping guide sleeve 2 is in the highest position.

[0057] In the actual pressing process, when the product flows into the pallet and reaches its position, the retaining ring 6 needs to be placed above the retaining ring groove by the gripper. The position sensor can detect the position of the retaining ring 6 and then send a signal to the vertical drive mechanism. The vertical drive mechanism then moves, driving the retaining ring fixing seat 1 to move vertically downward. As the bottom of the sleeve shaft moves downward, the position of the retaining ring is gradually corrected, and finally the retaining ring 6 is fitted onto the bottom of the sleeve shaft. The forward positioning sensor illuminates and signals, and the cylinder self-locks.

[0058] like Figure 5 As shown, the rear slider 4 moves horizontally to the left. During the movement, the inclined elongated hole 41 on the slider 4 gradually slides to the left. The inclined surface of the inclined elongated hole 41 drives the transmission shaft 3 and the clamping guide sleeve 2 fixedly connected to it to move downward. That is, under the action of the horizontal driving force of the slider 4, the inclined surface of the inclined elongated hole 41 converts the horizontal driving force into a vertically downward driving force. The vertically downward driving force drives the clamping guide sleeve 2 downward, which can press down the snap ring 6 and push the snap ring 6 into the sealing cover of the air chamber of the product, so as to realize the snap ring 6 is detached from the snap ring 6 fixing seat and snapped into the snap ring groove.

[0059] In this embodiment, the position of the snap ring 6 is corrected by the bottom of the snap ring fixing seat 1, and it is arranged and maintained coaxially with the snap ring groove. Then, the horizontal driving force is converted into a vertical downward force to disengage the snap ring 6 from the snap ring fixing seat 1 and press it into the snap ring groove. This ensures that the snap ring 6 always corresponds to the position of the snap ring groove during the snap ring groove insertion process, thereby ensuring that the snap ring 6 is accurately pressed into the snap ring groove.

[0060] When slider 4 retracts, rotating shaft 3 drives the clamping guide sleeve 2 upward, and slider 4 returns to its original position. The vertical drive mechanism retracts, driving the snap ring fixing seat 1 upward back to its initial position. Snap ring 6 assembly is complete, the pallet is released, and it awaits the arrival of the next product pallet. The entire mechanism operates smoothly, greatly improving production cycle time and equipment utilization.

[0061] This embodiment has a simple and reasonable structure, which facilitates manufacturing, assembly, adjustment, inspection, and maintenance; it reduces the defect rate, greatly improves production cycle time, and has stable performance.

[0062] Example 2:

[0063] like Figure 4 , Figure 5 As shown, based on Embodiment 1, the sealing cover snap ring clamping assembly mechanism of this embodiment further includes a horizontal drive mechanism 5. The horizontal drive mechanism 5 includes a connecting bracket 51 and a pressing cylinder 52. One end of the connecting bracket 51 is connected to the top of the snap ring fixing seat 1, and the pressing cylinder 52 is horizontally connected to the other end of the connecting bracket 51.

[0064] In this embodiment, the connecting bracket 51 has a Z-shaped structure, aligning the central axis of the driving end of the pressing cylinder 52 with the center line of the slider 4 to ensure the horizontal driving force is horizontal. The Z-shaped connecting bracket 51 ensures stability and vibration-free operation of the cylinder.

[0065] During use, when the product flows into the pallet and reaches its position, the feeding gripper sends the snap ring 6 onto the product's sealing cover. The snap ring fixing seat 1 is pushed downward by the vertical cylinder, and the forward positioning sensor illuminates, triggering the vertical cylinder to self-lock. At this point, the snap ring 6 is firmly fitted into the bottom of the sleeve shaft. The pressing cylinder 52 actuates, and the slider 4 drives the transmission shaft 3 to move within the inclined elongated hole 41. Subsequently, the clamping guide sleeve 2 connected to the transmission shaft 3 moves downward, and the pressing cylinder 52 advances to its position, illuminating the positioning sensor. This pushes the snap ring 6 into the sealing cover of the product's upper air chamber. The pressing cylinder 52 then retracts, and the rotating shaft 3 drives the clamping guide sleeve 2 upward. After the pressing cylinder 52 retracts and the positioning sensor illuminates, the vertical cylinder retracts, driving the snap ring fixing seat 1 upward back to its initial position. The snap ring 6 assembly is complete, and the pallet is released.

[0066] It should be noted that the technical effect achieved in this embodiment can be achieved even when the slider 4 is not completely horizontal. That is, the slider 4 can rotate a small angle counterclockwise or clockwise in the horizontal direction, which can be controlled within 10 degrees, and the horizontal driving force can still be converted into the vertical driving force.

[0067] It should be noted that the first rectangular groove 11 and the second rectangular groove 21 can also be omitted. The front and rear front sides of the larger upper part of the clamping guide sleeve 2 can be cut into planes, and the slider 4 can be a U-shaped frame. The slider 4 is located outside the front and rear sides of the clamping guide sleeve 2, and the drive shaft 3 is fixedly connected to the plane of the clamping guide sleeve 2. Inclined elongated holes 41 are also provided on both sides of the slider 4. The drive shaft 3 passes through the inclined elongated holes 41, which can also convert the horizontal driving force into the vertical driving force. The above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
