Description

Technical Field

[0001] This application relates to the technical field of automotive piping assembly, and in particular to an automotive piping assembly device. Background Technology

[0002] In automobile manufacturing, the connection of pipes and fittings is a common and critical assembly step, especially in the connection of fuel, cooling, and braking systems. The reliability of this connection directly affects the safety and performance of the entire vehicle. Currently, the mainstream technology for this step still relies heavily on manual operation. A typical process involves the operator first placing the fitting on a pre-set support rod, then fitting a metal retaining ring onto the outer wall of the fitting, then passing the pipe through the retaining ring and inserting the fitting into the pipe, and finally riveting the retaining ring using a riveting cylinder to achieve a fixed connection between the pipe and the fitting. In this process, the diameter of the retaining ring is larger than the diameter of the pipe, and the diameter of the pipe is larger than the diameter of the fitting.

[0003] However, this traditional assembly method has obvious technical shortcomings. In the process of inserting the metal retainer into the pipe end, the operator needs to manually move the mold holding the pipe to accurately align the pipe end and insert it into the inner hole of the metal retainer. Because the fit between the metal retainer and the pipe end is small and the alignment requirement is high, this manual alignment process is not only cumbersome and slow, resulting in excessive assembly time for a single piece, it has become a bottleneck to improving the overall efficiency of the production line. Furthermore, because it relies entirely on human judgment and hand stability, it is difficult to guarantee the consistency of assembly quality. It is easy to cause potential quality risks such as pipe damage and incomplete assembly due to alignment deviations, which in turn affect the sealing performance and long-term reliability of the pipeline system. Summary of the Invention

[0004] An automotive pipe assembly device is provided to enable automatic and rapid alignment and insertion of pipe ports and metal retaining rings.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: An automotive pipe assembly device includes a base and a body mounted on the base. The base is provided with a support assembly for placing a joint, a riveting assembly for riveting a snap ring, and a feeding assembly for conveying pipes, respectively. The feeding assembly includes an upper feeding seat and a lower feeding seat aligned vertically. The lower feeding seat slides on the base toward the riveting assembly. The lower feeding seat has a receiving groove for inserting a pipe, and the end of the pipe toward the riveting assembly is coaxially arranged with the retaining ring and the connector. The lower feed seat has a clearance groove on the side facing the riveting assembly; a positioning assembly is slidably provided in the clearance groove along the sliding direction of the lower feed seat. The positioning assembly includes a driving member and a positioning member located on both sides of the pipe. The driving member can drive the positioning member to press against the outer wall of the pipe to limit its radial movement. The positioning member includes a clamping part for clamping the outer wall of the pipe and a limiting part for passing through the retaining ring.

[0006] By adopting the above technical solution and integrating a sliding positioning component into the lower feed seat, the entire process of pipeline conveying, positioning, centering and release is automated and precise. Throughout the pipeline conveying process to the riveting station, the positioning component continuously limits and centers the pipeline radially, completely preventing the pipeline from shifting during movement. The limiting part actively passes through the retaining ring to achieve the final positioning of the pipeline and the forced calibration of the joint axis, ensuring the centering of the joint and pipeline during insertion. After the insertion is completed, the positioning component can automatically release the clamp and withdraw, freeing up operating space for the riveting process. This solves the problems of low efficiency, poor consistency and insufficient accuracy of traditional manual centering, and fully realizes the high efficiency, precision and reliable automation of automotive pipeline joint assembly.

[0007] Preferably, the positioning element is a semi-annular structure that abuts against the outer circumferential wall of the pipe.

[0008] By adopting the above technical solution, the positioning component can cover the outer wall of the pipe with an optimized contact area and force distribution, ensuring stable clamping and precise alignment while avoiding damage to the pipe surface. Its simple geometry also reduces manufacturing complexity and cost.

[0009] Preferably, the length of the clamping part in the radial direction of the pipe is greater than the length of the limiting part in the radial direction of the pipe.

[0010] By adopting the above technical solution, the clamping force applied by the driving component acts on the clamping part, while the reaction force of the pipe on the clamping part is evenly distributed on the inner wall of the clamping part, thereby increasing the rigidity of the main load-bearing area of ​​the clamping part.

[0011] Preferably, a gap is left between the outer wall of the limiting part and the inner wall of the retaining ring.

[0012] By adopting the above technical solution, the gap left is the physical basis for the positioning component to perform the withdrawal action after completing the insertion task. When the driving component drives the positioning component to release radially, the positioning component can retract away from the pipe within this gap, so that it can smoothly and without interference disengage from the assembled pipe and retaining ring when axially retracting. This effectively prevents the risk of the positioning component not retracting smoothly and causing the pipe to be driven in reverse, resulting in loose assembly, and ensures the smoothness, reliability and high yield of the entire assembly cycle.

[0013] Preferably, the end of the limiting part is flush with the end of the pipe.

[0014] By adopting the above technical solution, the positioning reference is precisely set on the actual assembly surface of the pipe and the joint, so that the limiting part can restrict the spatial position of the pipe end, ensuring that the pipe end that the joint can contact is always on the preset precise axis, which significantly reduces the risk of insertion damage, thereby ensuring the absolute accuracy and high reliability of the pipe and joint insertion action from the root.

[0015] Preferably, an adjusting cylinder is fixedly connected in the clearance groove, and an adjusting plate for mounting the positioning component is provided in the clearance groove. The telescopic end of the adjusting cylinder is fixedly connected to the adjusting plate.

[0016] By adopting the above technical solution, the positioning components on both sides of the pipeline are integrated into a whole motion unit, and a high-rigidity synchronous motion mechanism is constructed to ensure the synchronous movement of the driving components on both sides of the pipeline and eliminate pipeline deflection caused by asynchronous driving.

[0017] Preferably, a limit rod is vertically fixed on the adjustment plate, and a limit switch electrically connected to the driving component is provided on the limit rod.

[0018] By adopting the above technical solution, it is ensured that when the limiting part needs to be withdrawn, the driving component drives the clamping part to move to a preset safe position and is immediately stopped. This maintains a precise safe gap between the outer wall of the limiting part and the inner wall of the retaining ring, preventing the limiting part from scraping or interfering with the retaining ring when withdrawing in the radial direction of the pipeline, thereby improving the accuracy of the entire withdrawal process and the reliability of equipment operation.

[0019] Preferably, the riveting assembly includes an upper riveting seat and a lower riveting seat aligned with each other. The lower riveting seat is used to place the retaining ring. A riveting cylinder is fixed on the machine body to drive the upper riveting seat to move toward the lower riveting seat. The stroke of the riveting cylinder driving the upper riveting seat to press down includes two stages: the first stage is driving the upper riveting seat to pre-press against the retaining ring, and the second stage is driving the upper riveting seat to fully press down and tighten the retaining ring.

[0020] By adopting the above technical solution, the pre-pressing action in the first stage stabilizes the retaining ring on the lower riveting seat when the limiting part passes the retaining ring, preventing the retaining ring from shifting or falling off due to collision with the limiting part or equipment vibration. This eliminates the assembly uncertainty caused by the change in the position of the retaining ring, ensures the centering accuracy, and finally completes high-quality riveting through the second stage of the stroke, thereby realizing an optimized assembly process of stabilization first, operation later, and final shaping.

[0021] Preferably, the support assembly includes a support base, an adjustment seat is rotatably mounted on the support base, and a support rod for placing a connector is fixedly mounted on the side wall of the adjustment seat. A limiting cylinder is provided on one side of the support base, and a limiting member for pressing down the adjustment seat is fixedly mounted on the telescopic end of the limiting cylinder.

[0022] By adopting the above technical solution, and by setting a rotatable adjusting seat and a locking mechanism driven by a limit cylinder, the problem of difficult joint loading in a compact space is solved. Operators can rotate the support rod to an open area by rotating the adjusting seat, and load the joint in a more ergonomic lateral placement manner. This completely avoids the limitation of insufficient axial operating space, and improves the convenience of operation and material changing efficiency while ensuring the accuracy of assembly reference.

[0023] In summary, this application has at least the following beneficial effects: 1. The equipment integrates the conveying of the pipe toward the riveting process and the radial positioning function through the sliding positioning component in the feeding assembly. The positioning component, which has both a clamping part and a limiting part, can continuously provide radial constraint during the pipe conveying process, and at the final station, the limiting part actively passes through the retaining ring, realizing the forced alignment of the pipe axis and the joint axis, eliminating the risk of pipe insertion damage caused by visual deviation or manual operation. 2. The gap design between the limiting part and the inner wall of the retaining ring, as well as the precise withdrawal logic controlled by the limit switch, ensure that the limiting part can smoothly and without interference withdraw to the outside of the retaining ring after positioning, freeing up operating space for subsequent riveting processes; 3. The two-stage pressing stroke of the riveting assembly first fixes the retaining ring by pre-pressing, and then performs full riveting. This effectively prevents displacement caused by the retaining ring moving in and out of the limiting part, and ensures the stability of the riveting quality. Attached Figure Description

[0026] The following section provides a more detailed description, in conjunction with the accompanying diagrams: As attached Figure 1 and attached Figure 2 As shown, an automotive pipe joint assembly device includes a base 1, a machine body 11, a support component 2 for placing the joint, a riveting component 4 for riveting the snap ring 3, and a feeding component 6 for conveying the pipe 5. The machine body 11 is vertically fixedly connected to the base 1. The support component 2, the riveting component 4, and the feeding component 6 are sequentially arranged on the base 1 along the process flow direction (usually a straight line) of the pipe 5 assembly and are located below the machine body 11.

[0027] As attached Figure 2 and attached Figure 3 As shown, the support assembly 2 includes a support base 21 and an adjustment base 22. The support base 21 includes a mounting part 211 and a support part 212. The mounting part 211 is a plate-shaped structure, and the support part 212 is a block-shaped structure located above the mounting part 211. The mounting part 211 is fixedly mounted on the base 1 by bolts. In order to improve the stability and life of the equipment during the riveting process, fixed columns 2121 are installed at the four corners of the support part 212 along the vertical direction. Buffer grooves 212 are opened at the four corners of the support part 212 facing the mounting part 211. The fixed columns 2121 are located in the buffer grooves 2122, and buffer springs 23 are installed in the buffer grooves 2122 and sleeved on the outer wall of the fixed columns 2121. The two ends of the buffer springs 23 are respectively abutted against the support part 212 and the mounting part 211 to absorb and buffer the impact vibration generated during riveting.

[0028] As attached Figure 2 and attached Figure 4As shown, the adjusting seat 22 is rotatably connected to the support seat 21 via a pin 24. A through rotating hole 221 is opened at the bottom of the adjusting seat 22. The end of the pin 24 passes through the corresponding shaft hole on the support seat 21 and is inserted into the rotating hole 221. The adjusting seat 22 can rotate in the horizontal plane around the axis of the pin 24. When the support rod 25 or the adjusting seat 22 is worn due to long-term use or needs to be replaced to adapt to different types of connectors, the entire adjusting seat 22 assembly can be quickly removed and replaced simply by pulling out the pin 24.

[0029] A support rod 25 is integrally formed or fixedly connected to the side wall of the adjusting seat 22 facing the riveting assembly 4. The support rod 25 is preferably cylindrical in shape, with a chamfer at its end to facilitate the insertion of the connector. The shape and size of the support rod 25 should be adapted to the inner hole of the automotive pipe connector to be assembled to ensure that the connector can be stably and accurately fitted onto the outer wall of the support rod 25.

[0030] A limiting cylinder 26 is provided on the side of the support base 21 away from the support rod 25. The limiting cylinder 26 is vertically fixed to the base 1. A limiting member 27 for pressing down the top of the adjusting seat 22 is fixed on the end of the telescopic end of the limiting cylinder 26. The limiting member 27 is L-shaped. After rotating the adjusting seat 22 and fitting the connector onto the outer wall of the support rod 25, the telescopic end of the limiting cylinder 26 extends. The limiting cylinder 26 will drive the limiting member 27 to press down the adjusting seat 22, restricting the rotation of the adjusting seat 22 and thus limiting and fixing the adjusting seat 22 to prevent it from shaking or shifting during assembly, and ensuring the positional accuracy of the connector.

[0031] As attached Figure 5 As shown, the riveting assembly 4 includes an upper riveting seat 41, a lower riveting seat 42, and a riveting cylinder 43. The lower riveting seat 42 is located on the side of the support base 21 facing away from the limiting cylinder 26. The lower riveting seat 42 is fixedly installed on the base 1, and the upper riveting seat 41, the lower riveting seat 42, and the riveting cylinder 43 are located in the same vertical direction. The riveting cylinder 43 is fixedly connected to the top of the machine body 11, and the upper riveting seat 41 is fixedly connected to the telescopic end of the riveting cylinder 43. The upper riveting seat 41 and the lower riveting seat 42 are aligned vertically with each other, and semi-annular openings are respectively opened on the opposite side of the upper riveting seat 41 and the lower riveting seat 42. Each opening is fixed with a clamping member 44 for pressing down and tightening the retaining ring 3. After the retaining ring 3 is placed on the clamping member 44 of the lower riveting seat 42, the riveting cylinder 43 drives the upper riveting seat 41 to move down, so that the upper and lower clamping members 44 tighten the retaining ring 3, and the retaining ring 3 and the joint are coaxially arranged.

[0032] As attached Figure 6 and attached Figure 7As shown, the feeding assembly 6 includes a lower feeding seat 61 and an upper feeding seat 62. The lower feeding seat 61 is located on one side of the lower riveting seat 42. Two rows of relatively parallel slide rails 12 are fixedly connected to the base 1. The slide rails 12 are arranged along the direction of the lower feeding seat 61 toward the lower riveting seat 42. Sliding members 13 are slidably provided on the two slide rails 12 respectively. The shape of the sliding member 13 is rectangular block. The top of the sliding member 13 is fixedly connected to the bottom of the lower feeding seat 61. A first feeding cylinder 63 is also fixedly connected to the base 1 along the installation direction of the slide rails 12. The telescopic end of the first feeding cylinder 63 is fixedly connected to the side wall of the two sliding members 13. Thus, the extension and retraction of the telescopic end of the first feeding cylinder 63 can drive the lower feeding seat 61 to move toward or away from the lower riveting seat 42.

[0033] The surface of the lower feed seat 61 has a receiving groove 611 for inserting the pipe 5. The shape and size of the receiving groove 611 are adapted to the partial shape of the automobile pipe 5 to be assembled, and are used to stably support the pipe 5 during the conveying process. A vertical fixing plate 64 is fixedly connected to the side of the lower feed seat 61 near the machine body 11. A vertical second feeding cylinder 65 is fixedly connected to the side of the fixing plate 64 near the lower feed seat 61. The upper feed seat 62 is aligned with the lower feed seat 61 in the vertical direction. The upper feed seat 62 is fixedly connected to the telescopic end of the second feeding cylinder 65.

[0034] The extension and retraction of the telescopic end of the second feed cylinder 65 can drive the upper feed seat 62 to press down toward the lower feed seat 61. Since the automotive pipe 5 is mostly curved, one end of the pipe 5 is stably clamped in the receiving groove 611 of the lower feed seat 61, while the other end of the pipe 5 extends toward the lower riveting seat 42. When it is finally fed into place, it achieves precise coaxial alignment with the joint on the support rod 25 and the retaining ring 3 placed on the lower riveting seat 42.

[0035] The upper surface of the lower feed seat 61 facing the riveting assembly 4 has a clearance groove 612. A positioning assembly 7 is slidably provided in the clearance groove 612 along the sliding direction of the lower feed seat 61. The positioning assembly 7 includes a driving member 71 and a positioning member 72 located on both sides of the pipe 5. The driving member 71 can be a driving device such as a cylinder or an electric push rod. Here, an electric push rod is preferred. The two positioning members 72 are respectively fixedly connected to the ends of the two driving members 71. Thus, the driving member 71 can drive the positioning member 72 to move in a direction perpendicular to the sliding direction of the lower feed seat 61. Thus, the positioning member 72 is pressed against the outer wall of the pipe 5 and radially limits the pipe 5.

[0036] As attached Figure 6 and attached Figure 8As shown, the positioning element 72 is a high-strength rigid structure. It is a semi-annular structure that abuts against the outer circumferential wall of the pipe 5, allowing it to cover the outer wall of the pipe 5 with optimized contact area and force distribution, thus improving the clamping and positioning effect. The positioning element 72 includes a clamping part 721 and a limiting part 722. The end of the positioning element 72 closer to the lower rivet base 42 is the limiting part 722, and the end of the positioning element 72 further away from the lower rivet base 42 is the clamping part 721. The limiting part 722 and the clamping part 721 are integrally formed. (The last sentence appears to be incomplete and possibly refers to a retaining ring.) The diameter of 3 is larger than the diameter of pipe 5, and the diameter of pipe 5 is larger than the diameter of the joint. Therefore, when the driving member 71 drives the positioning member 72 to abut against the circumferential outer wall of pipe 5, the distance between the two limiting parts 722 is smaller than the diameter of the retaining ring 3. When the feed seat 61 moves toward the lower riveting seat 42, the limiting part 722 will continue to clamp on the outer wall of pipe 5 and pass through the retaining ring 3 to the joint. The clamping part 721 is located outside the retaining ring 3, realizing the final positioning of pipe 5 and the forced calibration of the joint axis, ensuring the alignment of the joint and pipe 5 when they are inserted.

[0037] The end of the limiting part 722 is flush with the end of the pipe 5, and the positioning reference is precisely set on the actual assembly surface of the pipe 5 and the joint, so that the limiting part 722 can restrict the spatial position of the end of the pipe 5, ensuring that the end of the pipe 5 that the joint can contact is always on the preset precise axis.

[0038] The length of the clamping part 721 in the radial direction of the pipe 5 is greater than the length of the limiting part 722 in the radial direction of the pipe 5. The clamping force applied by the driving member 71 acts on the clamping part 721, while the reaction force of the pipe 5 on the clamping part 721 is evenly distributed on the inner wall of the clamping part 721, thereby increasing the rigidity of the main load-bearing area of ​​the clamping part 721.

[0039] There is a gap between the outer wall of the limiting part 722 and the inner wall of the retaining ring 3. When the driving part 71 drives the positioning part 72 to release radially, the positioning part 72 can retract and move away from the pipe 5 in this gap, so that it can smoothly and without interference disengage from the assembled pipe 5 and retaining ring 3 when axially retracting, effectively preventing the risk of the positioning component 7 not retracting smoothly and causing the pipe 5 to be driven in the opposite direction, resulting in loosening of the assembly.

[0040] An adjusting cylinder 73 is fixedly connected inside the clearance groove 612 along the sliding direction of the lower feed seat 61. An adjusting plate 74 is also provided inside the clearance groove 612 for the fixed installation of the two driving components 71. The telescopic end of the adjusting cylinder 73 is fixedly connected to the adjusting plate 74. The adjusting cylinder 73 can drive the adjusting plate 74 to slide inside the clearance groove 612 along the sliding direction of the lower feed seat 61, thereby adjusting the position of the positioning component 7, ensuring the synchronous movement of the driving components 71 on both sides of the pipe 5, so that the two limiting parts 722 can be simultaneously withdrawn outside the retaining ring 3, leaving space for the riveting process of the riveting component 4.

[0041] A limit rod 75 is vertically fixed on the adjusting plate 74. A limit switch 76 electrically connected to the driving member 71 is provided on the limit rod 75. When the driving member 71 drives the clamping part 721 to move away from the pipe 5, the limit switch 76 can limit the distance of movement of the clamping part 721. The limit switch 76 on the limit rod 75 will sense the position signal of the clamping part 721 and transmit the signal to the driving member 71 to control the driving member 71 to stop driving the positioning part 72 to move, so as to prevent the limit part 722 from scraping or interfering with the retaining ring 3 and the pipe 5 when it moves away from the pipe 5 in the retaining ring 3.

[0042] As attached Figure 5 and attached Figure 6 As shown, the stroke of the riveting cylinder 43 driving the upper riveting seat 41 to press down includes two stages. The riveting cylinder 43 can also be replaced by other types of driving devices such as hydraulic cylinders, as long as it can achieve the two-stage pressing stroke of the upper riveting seat 41. The first stage is to drive the upper riveting seat 41 to pre-press against the retaining ring 3. Through the pre-pressing action of the first stage, when the limiting part 722 passes the retaining ring 3, the retaining ring 3 is stably clamped on the lower riveting seat 42 in advance, preventing the retaining ring 3 from shifting or falling off due to collision with the limiting part 722 or equipment vibration. The second stage is to drive the upper riveting seat 41 to fully press down and clamp the retaining ring 3. After the limiting part 722 exits the retaining ring 3, the riveting cylinder 43 performs the second stage to clamp and fix the joint, pipe 5 and retaining ring 3, thereby realizing an optimized assembly process of stabilization first, operation later, and final forming.

[0043] The implementation principle of this embodiment is as follows: The support assembly 2 cooperates with the limiting cylinder 26 through the rotatable adjusting seat 22 to facilitate the loading and fixing of the joint. The pipe 5 is placed in the receiving groove 611 of the lower feeding seat 61 and the upper feeding seat 62 is driven by the second feeding cylinder 65 to press down and limit the pipe 5. The driving component 71 drives the positioning component 72 to radially clamp and limit the pipe 5 at the outer end. Then, the lower feeding seat 61 is driven by the first feeding cylinder 63 to transport the pipe 5 to the riveting process. The positioning component 72 is designed as a semi-ring structure that combines the clamping part 721 and the limiting part 722. The clamping part 721 is responsible for stabilizing the pipe 5, while the limiting part 722 actively passes through the retaining ring 3 when the pipe 5 moves forward to ensure continuous limiting of the pipe 5 and achieve forced alignment between the pipe 5 and the joint axis. After alignment is completed, the positioning component 72 is released and withdrawn by the driving component 71 to avoid interfering with the subsequent riveting process. The riveting assembly 4 adopts a two-stage stroke. First, the stabilizing retaining ring 3 is pre-pressed to ensure that the withdrawal of the limiting part 722 will not interfere with the retaining ring 3. Then, it is fully riveted and fixed to ensure assembly quality.

[0044] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
