Description

Technical Field

[0001] This invention relates to the field of automotive and motorcycle parts production equipment technology, and in particular to a production equipment for automotive and motorcycle parts. Background Technology

[0002] Automotive and motorcycle parts are components for cars and motorcycles, naturally including car parts. There are many types of automotive and motorcycle parts, covering almost all car and motorcycle components, such as engines, transmissions, electrical systems, tires, braking systems, and so on. Parts are the individual units that make up a whole and a product that serves the whole. With the increasing variety of automotive parts and people's rising living standards, the market for vehicle parts is growing larger and larger.

[0003] The production of automobiles and motorcycles requires various tubular parts, including piston rings, which are manufactured through the machining of tubular components. Piston rings are a crucial component in automotive and motorcycle parts, primarily used in piston assemblies within automobile engines. They are ring-shaped parts, typically made of steel or cast iron, installed around the outer circumference of the piston. Their main function is to form a good seal with the cylinder wall, preventing gas leakage from the combustion chamber and maintaining engine compression and power output. This helps improve engine power output and fuel efficiency.

[0004] Currently, in the processing of piston rings, operators need to manually position them multiple times to ensure accuracy when processing different models. This is not only time-consuming and labor-intensive, but also significantly increases labor intensity, leading to low production efficiency and making it difficult to meet the demands of rapid production and flexible switching. Furthermore, due to the lack of automated and intelligent adjustment mechanisms, the production of different piston ring models requires different processing parameters and equipment configurations. To adapt to these changes, operators have to perform tedious manual adjustments, which not only affects the continuity of the production line but also increases the risk of human error. Over time, this not only impacts production efficiency but may also negatively affect the processing quality of the piston rings. Summary of the Invention

[0005] The main objective of this invention is to provide a production equipment for automotive and motorcycle parts, which aims to effectively improve production efficiency, reduce manual intervention, and enhance the stability and precision of the processing.

[0006] To achieve the above objectives, the present invention provides a production equipment for automotive and motorcycle parts, comprising:

[0007] The workbench and the automatic hole-making machine for cutting and processing pipe fittings are provided. The workbench is fixedly connected to the automatic hole-making machine. A work plate is rotatably connected to the workbench. A drive module for driving the work plate to rotate automatically on the workbench is connected between the workbench and the work plate. Several open sleeves are connected to the work plate.

[0008] The compression module is used to tightly compress tubular components into open sleeves;

[0013] The positioning and clamping assembly is used to position and clamp open sleeves of different sizes.

[0014] In one possible implementation, the positioning and clamping assembly includes several positioning blocks and a linkage assembly. Each positioning block is slidably connected to the working plate. Each positioning block has two transmission plates hinged to it. Each transmission plate is rotatably connected to the working plate. A limit block is hinged to the end of each transmission plate away from the positioning block. Each limit block is slidably connected to the working plate. A limit post is connected to each limit block. A positioning ring is detachably hinged to one end of each limit post. An open sleeve is disposed between two positioning rings. The inner wall of the positioning rings is tightly fitted to the outer wall of the open sleeve. The linkage assembly is used to synchronously adjust the distance between each positioning block and the center of the working plate.

[0015] In one possible implementation, a locking plate is fixedly connected to the end of the limiting post away from the positioning ring sleeve. Each limiting post is fitted with a limiting spring. The two ends of the limiting spring abut against the limiting block and the locking plate, respectively. A locking groove is provided on the limiting block. A locking protrusion is fixedly connected to the outer wall of the positioning ring sleeve. The locking protrusion is fitted into the inner wall of the locking groove.

[0016] In one possible implementation, an anti-slip pad is fixedly connected between the positioning ring and the open sleeve to improve the positioning effect of the positioning ring on the open sleeve.

[0017] In one possible implementation, transmission grooves are provided near both ends of the transmission plate, and the positions where the positioning block is hinged to the transmission plate and the positions where the transmission plate is hinged to the limiting block are both in contact with the inner walls of the adjacent transmission grooves.

[0018] In one possible implementation, a stepped ring is fixedly connected to the outer ring of the open sleeve, and a limiting ring is fixedly connected to the inner wall of the positioning ring for fitting the stepped ring.

[0019] In one possible implementation, the linkage assembly includes an adjusting gear ring and a motor base. The adjusting gear ring is rotatably connected to the working disc, and an adjusting gear meshes with the outer ring of the adjusting gear ring. The motor base is fixedly connected to one side of the adjusting gear, and an adjusting motor is fixedly connected to the motor base. The drive shaft of the adjusting motor is fixedly connected to the adjusting gear. Several linkage plates are hinged to the outer wall of the adjusting gear ring, and the other end of each linkage plate is hinged to an adjacent positioning block.

[0030] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] This invention proposes a production equipment for automotive and motorcycle parts.

[0033] Reference Figures 1 to 6 The system includes a worktable 11, an automatic hole punching machine 12 for cutting and processing pipe fittings, a pressing module 15, a cutting module 16, an opening module, a grinding module 17, a top-loading cylinder 18, and a positioning and clamping assembly. The worktable 11 is fixedly connected to the automatic hole punching machine 12, and a work plate 13 is rotatably connected to the worktable 11. A drive module for automatically rotating the work plate 13 on the worktable 11 is connected between the worktable 11 and the work plate 13. Several open sleeves 14 are connected to the work plate 13. The pressing module 15 is used to tightly press the pipe fittings into the machine. In the open sleeve 14, the cutting module 16 is used to cut the tubular components set inside the open sleeve 14 at equal intervals, the opening module is used to limit the upper end of the open sleeve 14 and make the tubular components cooperate with the automatic hole punch 12 to make side openings, the grinding module 17 is used to grind several piston rings that have been cut and side-hole punched, the ejector cylinder 18 is used to eject the processed piston rings from the open sleeve 14, the ejector cylinder 18 is fixedly connected to the worktable 11, and the positioning and clamping assembly is used to position and clamp the open sleeves 14 of different sizes.

[0034] The positioning and clamping assembly, along with its linkage components, achieves a precise and efficient positioning process, ensuring that the distance between the two positioning rings 25 remains within a high-precision range, thus providing a high-precision positioning and clamping effect. This positioning method eliminates the need for tedious manual adjustments, and the automated process greatly improves the convenience and efficiency of operation. The tight fit between the inner wall of the positioning ring 25 and the outer wall of the open sleeve 14 not only ensures the precise positioning of the open sleeve 14 but also effectively guarantees the stability of the open sleeve 14 during processing, avoiding errors. This precise positioning method improves the machining accuracy of the piston rings installed in the open sleeve 14, ensuring the quality of the machining results. Simultaneously, it reduces manual intervention and operational complexity, making the entire machining process more stable and automated. The equipment's intelligence level is significantly improved, reducing the risk of errors caused by human operation, thereby enhancing the overall reliability and production efficiency of the equipment.

[0035] By selecting open sleeves 14 with different inner diameters, different models of piston rings can be flexibly adapted for processing, meeting diverse production needs. During production, the original workpiece for the piston ring is a tubular component, placed inside the open sleeve 14 and in close contact with the inner wall, thus achieving precise positioning. This design ensures the stability and efficiency of the tubular component during processing.

[0036] The rotary cylinder in the pressing module 15 is used to rotate and drive the pressing component to press the pipe fittings inside the open sleeve 14. The pressing module not only ensures that the pipe fittings are firmly clamped, but also provides sufficient clearance when lifted so that workers can easily install unprocessed pipe fittings or push the processed piston rings out of the open sleeve 14 through the ejector cylinder 18, which facilitates the transfer and collection of finished products.

[0037] Drive module and cutting module 16: The rotation of the working disc 13 is controlled by the drive module, ensuring that the pressed pipe moves to the underside of the cutting module 16. The cutting module 16 uses a cutting blade to perform circumferential cutting on the pipe, gradually dividing it into equidistant piston rings. This process achieves efficient cutting while ensuring cutting accuracy.

[0038] Hole-opening module and grinding module 17: After cutting, the piston rings enter the automatic hole-opening machine 12 as the working disc 13 rotates. The cutting blades on the automatic hole-opening machine 12 cut the piston rings along the opening position on the side of the open sleeve 14, forming a precise opening. This ensures that the sides of several piston rings are open. The processed piston rings continue to move to the grinding module 17. The grinding blocks in the grinding module 17, driven by a motor, perform fine grinding on the inner wall and opening of each piston ring, ensuring that the product surface is smooth and burr-free.

[0039] It is worth noting that the pressing module 15 and the opening module are fixedly connected to a retractable plate, which is rotatably connected to the worktable 13. This design ensures the relative positional accuracy between the processing modules, facilitating necessary adjustments by the operator and ensuring processing precision. This structural design not only improves the processing precision of the equipment but also makes maintenance more convenient and allows for rapid adaptation to different processing needs.

[0040] Overall, it effectively improves production efficiency, reduces manual intervention, enhances the stability and precision of the processing, and its modular structure facilitates adjustment and maintenance, thus optimizing the production process.

[0041] Reference Figures 2 to 6 The positioning and clamping assembly includes several positioning blocks 21 and a linkage assembly. Each positioning block 21 is slidably connected to the working plate 13. Two transmission plates 22 are hinged to the positioning blocks 21. Each transmission plate 22 is rotatably connected to the working plate 13. The end of each transmission plate 22 away from the positioning block 21 is hinged to each limiting block 23. Each limiting block 23 is slidably connected to the working plate 13. Each limiting block 23 is connected to each limiting post 24. One end of the limiting post 24 is detachably hinged to the positioning ring sleeve 25, preferably by a pin connection, to facilitate the removal of the positioning ring sleeve 25 by the worker and to facilitate its use with different types of piston rings. An open sleeve 14 is set between the two positioning ring sleeves 25. The inner wall of the positioning ring sleeve 25 is tightly fitted with the outer wall of the open sleeve 14. The linkage assembly is used to synchronously adjust the distance between each positioning block 21 and the center of the working plate 13.

[0042] The positioning and clamping assembly directly drives the positioning blocks 21 to slide, thereby pushing the positioning rings 25 towards the central open sleeve 14 for clamping and positioning. This design achieves a precise and efficient positioning process. Because the transmission plates 22 on both sides slide synchronously with the positioning blocks 21, the distance between the two positioning rings 25 is always maintained within a high-precision range, thus providing a high-precision positioning and clamping effect. This positioning method eliminates the need for tedious manual adjustments, and the automated process greatly improves the convenience and efficiency of operation. The tight fit between the inner wall of the positioning rings 25 and the outer wall of the open sleeve 14 not only ensures the precise positioning of the open sleeve 14 but also effectively guarantees the stability of the open sleeve 14 during processing, avoiding errors. Furthermore, this precise positioning method improves the machining accuracy of the piston rings installed in the open sleeve 14, ensuring the quality of the machining effect. At the same time, it reduces manual intervention and operational complexity, making the entire machining process more stable and automated. The intelligence level of the equipment has been significantly improved, reducing the risk of errors caused by human operation, thereby improving the overall reliability and production efficiency of the equipment.

[0043] Reference Figures 2 to 3 and Figure 6 The end of the limiting post 24 away from the positioning ring sleeve 25 is fixedly connected to the positioning plate 26. Each limiting spring 27 is sleeved on each limiting post 24. The two ends of the limiting spring 27 abut against the limiting block 23 and the positioning plate 26 respectively. The positioning groove 231 is opened on the limiting block 23. The positioning protrusion 28 is fixedly connected to the outer wall of the positioning ring sleeve 25. The positioning protrusion 28 is fitted into the inner wall of the positioning groove 231.

[0044] By engaging the locking protrusion 28 with the inner wall of the locking groove 231, the relative rotation angle between the limiting block 23 and the positioning ring sleeve 25 can be effectively limited. This design ensures that after the positioning ring sleeve 25 clamps and positions the open sleeve 14, the vibration and displacement generated by the piston rings inside the open sleeve 14 during processing will not affect the connection between the positioning ring sleeve 25 and the open sleeve 14. Specifically, through the engagement of the locking protrusion 28 and the locking groove 231, the relative position of the positioning ring sleeve 25 can be more stably controlled. This stability ensures that the limiting of the open sleeve 14 is more secure, avoiding inaccurate positioning or loosening due to vibration or displacement. At the same time, when the piston rings are processed inside the open sleeve 14, due to the more stable positioning, vibration and displacement are effectively suppressed, ensuring the accuracy of piston ring processing. In this way, the final processed piston rings are of higher quality, meeting the requirements of precision machining, thereby improving the processing effect and the overall quality of the product.

[0045] Reference Figures 2 to 3 and Figure 6 The anti-slip pad 251 is connected between the positioning ring sleeve 25 and the open sleeve 14 and is fixedly connected to the inner wall of the positioning ring sleeve 25 to improve the positioning effect of the positioning ring sleeve 25 on the open sleeve 14.

[0046] By adding an anti-slip pad 251 to the design, the contact performance between the positioning ring sleeve 25 and the open sleeve 14 can be effectively improved. The preferred embodiment of the anti-slip pad 251 is a soft material pad with a textured or striped surface. This design significantly reduces contact wear between the positioning ring sleeve 25 and the open sleeve 14 during the clamping process. Specifically, the anti-slip pad 251 effectively prevents tooth marks or other forms of damage to the outer side of the open sleeve 14 due to excessive clamping, thereby avoiding scratches and deformation of the surface of the open sleeve 14. This results in a gentler contact between the positioning ring sleeve 25 and the open sleeve 14, significantly extending their service life. Furthermore, the soft material of the anti-slip pad 251 has strong friction, effectively increasing the coefficient of friction between the positioning ring sleeve 25 and the open sleeve 14. During piston ring cutting, this enhanced friction provides more stable support and positioning, preventing slippage or displacement of the open sleeve 14, thus ensuring stability and accuracy during the cutting process. This not only improves processing quality but also enhances overall work efficiency, avoiding processing errors or equipment malfunctions caused by unstable positioning.

[0047] Reference Figures 2 to 4 Each transmission groove 221 is opened on the transmission plate 22 near both ends. The positions where the positioning block 21 is hinged to the transmission plate 22 and the positions where the transmission plate 22 is hinged to the limiting block 23 are both in contact with the inner wall of the adjacent transmission groove 221.

[0048] The preferred design is to hinge the positioning block 21 to the transmission plate 22, or hinge the transmission plate 22 to the limiting block 23. This design ensures that the positioning block 21 effectively drives the limiting blocks 23 on both sides to slide synchronously during the sliding process, thereby accurately positioning and clamping the open sleeve 14. Alternatively, other types of sliding hinges, such as rolling hinges or spherical hinges, can be used to further improve the stability and accuracy during the sliding process. These different connection methods ensure that the movement of the positioning block 21 is unimpeded and effectively transmits motion to the limiting blocks 23, allowing the two limiting blocks 23 to accurately clamp and stabilize the open sleeve 14, ensuring its fixation during processing, assembly, or transportation. The positioning block 21 and the limiting blocks 23 can slide synchronously, thus ensuring the accurate positioning of the open sleeve 14 between the two limiting blocks. This allows for higher machining accuracy of the fittings within the open sleeve 14, ensuring the quality of the final product. Furthermore, this automated synchronous sliding and clamping mechanism reduces the need for manual adjustments, lowers the incidence of human error, simplifies the operation process, and enhances the overall automation level of the production process. System maintenance is also relatively simpler. The connection method between components reduces wear and tear, lowers maintenance frequency, and extends the service life of the equipment.

[0049] Reference Figures 2 to 3 The stepped ring 141 is fixedly connected to the outer ring of the open sleeve 14, and the inner wall of the positioning ring sleeve 25 is fixedly connected to the limiting ring 252 to fit the stepped ring 141.

[0050] The tight fit between the limiting ring 252 and the stepped ring 141 significantly improves the positioning effect of the open sleeve 14. Supported by the stepped ring 141, the limiting ring 252 effectively fixes the position of the open sleeve 14, ensuring its stability during processing. Especially during the cutting process, the open sleeve 14 is less susceptible to displacement or shifting due to the cutting action, reducing errors caused by cutting and ensuring processing accuracy. When the piston ring workpiece inside the open sleeve 14 is cut, the force generated by the cutting may exert external force on the sleeve, causing displacement. The cooperation between the limiting ring 252 and the stepped ring 141 increases the contact area between the positioning ring sleeve 25 and the open sleeve 14, effectively limiting the movement of the open sleeve 14 and keeping it stable throughout the processing. This not only improves cutting accuracy but also avoids processing defects caused by sleeve displacement. Furthermore, the more stable limiting effect reduces rework and adjustment time due to inaccurate positioning, significantly improving production efficiency. This automated and precise limiting mechanism reduces the need for manual intervention, simplifies operation, and reduces the risk of operational errors.

[0051] Reference Figure 2 and Figure 5 The linkage assembly includes an adjusting gear ring 31 and a motor base 33. The adjusting gear ring 31 is rotatably connected to the working plate 13. The outer ring of the adjusting gear ring 31 meshes with the adjusting gear 32. The motor base 33 is fixedly connected to one side of the adjusting gear 32. The adjusting motor 34 is fixedly connected to the motor base 33. The drive shaft of the adjusting motor 34 is fixedly connected to the adjusting gear 32. The outer wall of the adjusting gear ring 31 is hinged to several linkage plates 35. The other end of each linkage plate 35 is hinged to the adjacent positioning block 21.

[0052] The adjusting motor 34 in the linkage assembly directly drives the adjusting gear ring 31 to rotate relative to the working plate 13, thereby precisely controlling the sliding distance of each positioning block 21 on the adjusting gear ring 31. This method not only precisely adjusts the position of the positioning blocks, but also automatically completes the limiting and fixing of each open sleeve 14 without manual operation. Through this innovative linkage mechanism, the coordinated work of the adjusting motor 34, adjusting gear ring 31, positioning blocks 21, and positioning and clamping assembly makes the entire processing process more efficient and precise, and also enables quick and convenient automated adjustment when changing piston ring workpieces of different models. The design of the linkage assembly reduces the reliance on manual positioning and clamping processes in traditional processing methods, avoiding errors and cumbersome operations that may be caused by manual intervention. It can quickly adjust the equipment settings when it is necessary to change to different models of piston rings for processing, significantly improving processing efficiency. Since manual positioning is no longer required, the equipment running time is greatly shortened, the production cycle is shortened, and the overall efficiency and automation level of the production line are greatly improved.
