Description

Technical Field

[0001] This application relates to the field of hydraulic suspension manufacturing technology, and in particular to a riveting mechanism for hydraulic suspension. Background Technology

[0002] Hydraulic mounts, as key shock-absorbing components in modern automobiles, play a crucial role in effectively isolating engine vibrations, improving vehicle comfort, and ensuring the stable operation of the powertrain. The structural strength and sealing performance of their housings have a decisive impact on the overall performance of the hydraulic mount. During the manufacturing process of hydraulic mounts, the riveting process of the housing is particularly critical, as it directly relates to the housing's sealing performance, structural strength, and the tightness of its fit with the internal rubber components.

[0003] For the specific requirement of hydraulic suspension housing riveting, there is currently no mature riveting mechanism on the market that can perfectly match it. Existing riveting technology is mostly used to match the processing requirements of other parts. For example, Chinese patent application "A rotary flanging mechanism for processing automotive conical suspension or chassis bushings" (application number: CN201320761390.5) discloses a mechanism including a rotating body and a mounting base located below the rotating body. At least one rotatable roller is provided on the outer side of the rotating body. The roller is inclined, with its upper and lower ends tilting inward. An arc-shaped extrusion groove is provided in the middle of the outer surface of the roller. Its advantage is that the rotating body rotates rapidly under the action of a hydraulic press, and the roller rotates simultaneously with the rotating body, resulting in high working efficiency. The arc-shaped extrusion groove in the middle of the outer surface of the roller compresses the support during processing. The upper edge of the support is deformed due to the heat generated by the extrusion, thus achieving the flanging effect. This mechanism has the advantages of high riveting strength and aesthetically pleasing flanging.

[0004] Currently available riveting mechanisms are not entirely suitable for the special shape and processing requirements of hydraulic mount housings due to their structure and working principle. Therefore, this application develops a new hydraulic mount riveting mechanism, providing a more reliable and efficient riveting solution for the manufacturing of hydraulic mounts. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a hydraulically suspended riveting mechanism that can achieve efficient, uniform and stable inward riveting, and can adapt to various specifications of housings to meet the needs of high-quality large-scale production.

[0006] The technical solution adopted in this application is as follows: a hydraulically suspended riveting mechanism, including a frame, a base plate installed at the bottom of the frame, a fixing fixture for installing the hydraulic suspension detachably mounted on the base plate, a drive electric cylinder installed at the top of the frame, a rotary motor installed at the rear of the frame, a connecting base movably connected to the output shaft of the drive electric cylinder, and the output shaft of the rotary motor connected to the connecting base through a connector, and a riveting head detachably mounted on the connecting base; the operation of the drive electric cylinder drives the rotary motor and the connecting base to move downward, and the operation of the rotary motor drives the connecting base to rotate around an axis.

[0007] Compared with existing technologies, the advantages of this application are as follows: First, the riveting mechanism of this application is designed specifically for the inward riveting requirements of hydraulic mount housings. Through precise control of the drive cylinder and rotary motor, the riveting head can rivet the hydraulic mount housing inward with uniform force and speed, ensuring the uniformity and stability of the riveting process. This application achieves uniformity, stability, and efficiency in the riveting process through the coordinated work of the drive cylinder and rotary motor. The drive cylinder provides stable linear motion power, ensuring that the riveting head can accurately reach the riveting position of the hydraulic mount; the rotary motor provides stable rotational motion, ensuring the motion accuracy and stability of the riveting head during the riveting process. This design not only improves the riveting quality but also significantly improves production efficiency, meeting the requirements of modern automotive manufacturing industry for high-quality, large-scale production.

[0008] Secondly, both the fixtures on the base plate and the riveting heads on the connecting base are detachable, allowing for quick replacement according to the shape and size of different hydraulic suspension housings. The detachable riveting heads on the connecting base can also be selected in different shapes and sizes to meet the riveting process requirements of various hydraulic suspension housings. This enables the mechanism to adapt to a variety of specifications and models of hydraulic suspension housings. This flexibility and versatility allow for rapid replacement of the fixtures and riveting heads to meet the riveting needs of different hydraulic suspension housings without requiring large-scale modifications or replacements to the entire mechanism.

[0009] In summary, this application provides a more reliable and efficient riveting solution for the manufacturing of hydraulic mounts through its precise riveting control, uniform and stable riveting process, adaptability to various specifications of hydraulic mount housings, and meeting the needs of the modern automotive manufacturing industry.

[0010] In some embodiments of this application, the top of the riveting head is inserted into the connecting base, and the connecting base is provided with an upper pin, which passes through the connecting base and the riveting head.

[0011] This quick-change connection method makes riveting head replacement more convenient and faster. Installation and disassembly can be completed with a simple operation of insertion and pin locking, improving the versatility and flexibility of the equipment. In actual production, suitable riveting heads can be quickly replaced according to the specifications and shapes of different hydraulic suspension housings, reducing equipment adjustment time and improving production efficiency.

[0012] In some embodiments of this application, the riveting head includes a connecting rod, a base shaft, and two pressure rollers. The connecting rod is vertically arranged, with its top inserted into a connecting base. The base shaft is horizontally arranged and fixedly installed at the bottom of the connecting rod.

[0013] This structural design provides the riveting head with stable mechanical connections and excellent motion performance. The combination of the connecting rod and the base shaft provides robust support for the pressure roller, ensuring that the roller maintains accurate position and trajectory during rotation, thereby achieving a uniform and stable riveting effect.

[0014] In some embodiments of this application, two pressure rollers are installed on the left and right ends of the base shaft, the two pressure rollers are symmetrically arranged, the pressure rollers are movably connected to the base shaft, and the pressure rollers can rotate around the base shaft when subjected to force.

[0015] The two symmetrically arranged pressure rollers apply force evenly to the hydraulically mounted housing, ensuring the uniformity and stability of the riveting process. The movable connection design between the pressure rollers and the base shaft allows the pressure rollers to rotate freely under force, further improving the smoothness and quality of the riveting process and avoiding riveting defects caused by pressure roller jamming.

[0016] In some embodiments of this application, the pressure roller is generally conical in shape, and the outer diameter of the pressure roller is larger than the inner diameter.

[0017] The conical pressure roller better adapts to the curved shape of the hydraulically mounted housing, providing a more uniform pressure distribution and resulting in a more precise fit to the housing's geometry.

[0018] In some embodiments of this application, a mounting base is provided on the substrate, the top surface of the mounting base is a mounting reference surface, the top of the fixing fixture matches the hydraulic suspension to be tested, and the bottom of the fixing fixture is inserted into the mounting base. A lower pin is provided on the mounting base, and the lower pin passes through the fixing fixture and is inserted into the output shaft of the rotary motor.

[0019] This quick-change structure makes replacing fixed fixtures much easier; installation and removal of fixed fixtures can be completed simply by inserting and locking with pins. This design improves the versatility and flexibility of the equipment, enabling it to quickly adapt to different sizes of hydraulic suspension housings, reducing equipment adjustment time and increasing production efficiency.

[0020] In some embodiments of this application, the fixed fixture is provided with a product identifier, and a fixture identification sensor is installed on one side of the mounting base. The fixture identification sensor is used to detect the product identifier on the fixed fixture.

[0021] The tooling identification sensor can automatically recognize product markings on fixed tooling, thereby determining the specifications and model of the hydraulic suspension to be processed, and automatically matching pre-stored riveting process parameters. This automatic identification function reduces human error, improves the automation level and production efficiency of the equipment, and ensures the accuracy and consistency of the riveting process.

[0022] In some embodiments of this application, a cleaning mechanism is provided on the rear side of the frame. The cleaning mechanism includes a column, a slide rail horizontally arranged on the upper part of the column, and a cleaning head installed on the slide rail.

[0023] The cleaning mechanism effectively cleans the riveting head, keeping its surface clean and free of impurities, thereby improving riveting quality and extending the service life of the riveting head. This cleaning mechanism design makes the cleaning process more convenient and efficient, reducing the workload and time required for manual cleaning and improving equipment maintenance efficiency.

[0024] In some embodiments of this application, a push cylinder is installed on one side of the slide rail. The output shaft of the push cylinder is connected to a cleaning head, and the operation of the push cylinder drives the cleaning head to move close to the riveting head. The cleaning head is also connected to a power cylinder, and the operation of the power cylinder drives the cleaning head to clean the riveting head.

[0025] The combined use of the push cylinder and the power cylinder enables automatic movement of the cleaning head and cleaning action, allowing the entire cleaning process to be completed automatically without manual intervention. This automated cleaning function further improves the equipment's operating efficiency and ease of maintenance.

[0030] The present application will now be described in detail with reference to the accompanying drawings.

[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] A hydraulically mounted riveting mechanism, as described in Embodiment 1 Figures 1 to 3The device includes a frame 1, with a base plate 2 mounted at its bottom. A detachable fixture 3 for mounting hydraulic suspensions is mounted on the base plate 2. A drive cylinder 4 is mounted at the top of the frame 1, and a rotary motor 5 is mounted at its rear. A connecting base 6 is movably connected to the output shaft of the drive cylinder 4. The output shaft of the rotary motor 5 is connected to the connecting base 6 via a connector. A riveting head 7 is detachably mounted on the connecting base 6. Both the fixture 3 on the base plate 2 and the riveting head 7 on the connecting base 6 are detachable, allowing for quick replacement according to the shape and size of different hydraulic suspension housings. The detachable riveting head 7 on the connecting base 6 can also be selected in different shapes and sizes to meet the riveting process requirements of different hydraulic suspension housings. This allows the mechanism to adapt to various specifications and models of hydraulic suspension housings. This flexibility and versatility enable the mechanism to quickly replace the fixture 3 and the riveting head 7 to meet the riveting needs of different hydraulic suspension housings without requiring large-scale modification or replacement of the entire mechanism.

[0033] The drive cylinder 4 drives the rotary motor 5 and the connecting base 6 to move downwards, and the rotary motor 5 drives the connecting base 6 to rotate around an axis. The riveting mechanism of this application is designed for the inward riveting requirement of the hydraulic suspension housing. Through the precise control of the drive cylinder 4 and the rotary motor 5, the riveting head 7 can rivet the hydraulic suspension housing inwards with uniform force and speed, ensuring the uniformity and stability of the riveting process.

[0034] Example 2, as Figures 1 to 3 As shown, the top of the riveting head 7 is inserted into the connecting base 6, and the connecting base 6 is equipped with an upper pin 8, which passes through the connecting base 6 and the riveting head 7. This quick-change connection method makes the replacement of the riveting head 7 more convenient and faster. Installation and disassembly can be completed through a simple operation of insertion and pin locking, improving the versatility and flexibility of the equipment. In actual production, the appropriate riveting head 7 can be quickly replaced according to the specifications and shape of different hydraulic suspension housings, reducing equipment adjustment time and improving production efficiency.

[0035] The riveting head 7 includes a connecting rod 9, a base shaft 10, and two pressure rollers 11. The connecting rod 9 is vertically positioned, with its top inserted into the connecting base 6. The base shaft 10 is horizontally positioned and fixedly installed at the bottom of the connecting rod 9. This structural design provides the riveting head 7 with stable mechanical connection and good motion performance. The combination of the connecting rod 9 and the base shaft 10 provides solid support for the pressure rollers 11, ensuring that the pressure rollers 11 maintain accurate position and movement trajectory during rotation, thereby achieving a uniform and stable riveting effect. This structure not only guarantees riveting quality but also improves the reliability and service life of the equipment.

[0036] Two pressure rollers 11 are mounted symmetrically on either side of the base shaft 10. The pressure rollers 11 are movably connected to the base shaft 10, and can rotate around the base shaft 10 under force. This symmetrical arrangement of the two pressure rollers 11 ensures uniform force is applied to the hydraulic suspension housing, guaranteeing the uniformity and stability of the riveting process. The movable connection between the pressure rollers 11 and the base shaft 10 allows the pressure rollers 11 to rotate freely under force, further improving the smoothness and quality of the riveting process and preventing riveting defects caused by jamming of the pressure rollers 11.

[0037] The pressure roller 11 has an overall conical structure, with its outer diameter larger than its inner diameter. This conical shape allows the pressure roller 11 to better adapt to the curved shape of the hydraulically mounted housing, providing a more uniform pressure distribution and resulting in a more precise fit to the housing's geometry. This structure reduces stress concentration points that may occur during the riveting process, improving the structural strength and sealing performance of the housing.

[0038] A mounting base 12 is provided on the base plate 2. The top surface of the mounting base 12 serves as the mounting reference surface. The top of the fixing fixture 3 is matched with the hydraulic suspension to be tested, and the bottom of the fixing fixture 3 is inserted into the mounting base 12. A lower pin 13 is provided on the mounting base 12, which passes through the fixing fixture 3 and inserts into the output shaft of the rotary motor. This quick-change structure makes the replacement of the fixing fixture 3 more convenient. The installation and removal of the fixing fixture 3 can be completed by a simple operation of insertion and pin locking. This design improves the versatility and flexibility of the equipment, enabling it to quickly adapt to hydraulic suspension housings of different specifications, reducing equipment adjustment time and improving production efficiency.

[0039] The fixed fixture 3 is equipped with a product identification mark, and a fixture identification sensor 15 is installed on one side of the mounting base 12. The fixture identification sensor 15 is used to detect the product identification mark on the fixed fixture 3. The fixture identification sensor 15 can automatically identify the product identification mark on the fixed fixture 3, thereby determining the specifications and model of the hydraulic suspension to be processed, and automatically matching the pre-stored riveting process parameters. This automatic identification function reduces human operation errors, improves the automation level and production efficiency of the equipment, and ensures the accuracy and consistency of the riveting process.

[0041] Example 3, as Figure 4 , Figure 5As shown, a cleaning mechanism 16 is provided on the rear side of the frame 1. The cleaning mechanism 16 includes a column 17, a slide rail 18 horizontally arranged on the upper part of the column 17, and a cleaning head 19 mounted on the slide rail 18. The cleaning mechanism 16 can effectively clean the riveting head 7, keeping its surface clean and free of impurities, thereby improving the riveting quality and extending the service life of the riveting head 7. This cleaning mechanism design makes the cleaning process more convenient and efficient, reduces the workload and time of manual cleaning, and improves the maintenance efficiency of the equipment.

[0042] A push cylinder 20 is installed on one side of the slide rail 18. The output shaft of the push cylinder 20 is connected to the cleaning head 19. When the push cylinder 20 operates, it moves the cleaning head 19 closer to the riveting head 7. The cleaning head 19 is also connected to a power cylinder 21. When the power cylinder 21 operates, it drives the cleaning head 19 to clean the riveting head 7. The combined use of the push cylinder 20 and the power cylinder 21 enables the automatic movement and cleaning action of the cleaning head 19. The entire cleaning process can be completed automatically without manual intervention. This automated cleaning function further improves the operating efficiency and maintenance convenience of the equipment.
