Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, and in particular to a shock absorber assembly press-fitting device. Background Technology

[0002] In the manufacturing process of shock absorber assemblies, the press-fitting of the support arm and main spring assembly is crucial, as its assembly accuracy and quality directly affect the performance and service life of the shock absorber.

[0003] The manufacturing process of automotive engine shock absorber brackets involves press-fitting. Relevant existing technologies include Chinese patent application "An Automatic Press-fitting Device for Automotive Shock Absorbers", application number: CN202111270118.2, which discloses a device including a body, an electric slide rail, a hydraulic cylinder, and a base. The electric slide rail is located on the left and right sides of the inner cavity of the body. The hydraulic cylinder is fixedly connected to the top of the inner cavity of the body by bolts. The base is located at the bottom of the inner cavity of the body. Adjustable feet are fixedly connected to the four corners of the bottom of the body.

[0004] Existing engine shock absorber assembly press-fitting equipment has certain shortcomings in practical applications. The shock absorber assembly consists of press-fitted control arms and main spring assemblies. The control arms often have irregular structures, complex shapes, and numerous irregular edges and curved surfaces. This makes positioning and clamping the control arms on the press-fitting equipment difficult, hindering precise positioning and stable clamping. During the press-fitting process, the control arms are prone to displacement or tilting, resulting in substandard press-fitting accuracy and consequently affecting the overall performance and reliability of the shock absorber assembly. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a shock absorber assembly press-fitting device, which achieves precise positioning and stable installation of the support arm and the main spring through precise matching of the positioning pin and the pin seat, stable pressing of the rotating pressure head assembly and stable support of the lower mounting seat for the main spring, thereby improving the press-fitting accuracy and quality.

[0006] The technical solution adopted in this application is as follows: a shock absorber assembly press-fitting equipment, including an upper template and a lower template connected to a press. A mounting plate is fixed below the upper template. The mounting plate is set perpendicular to the upper template. Multiple pin seats are provided on the front side of the mounting plate corresponding to the through holes on the support arm. A positioning pin is provided on the front side of the pin seat. The support arm is hung on the front side of the mounting plate through the positioning pin. A rotating press head assembly is provided on the mounting plate. The rotating press head assembly works to press the support arm into the pin seat. A lower mounting seat is provided on the top surface of the lower template. The lower mounting seat includes a positioning component and multiple support components regularly distributed on the lower template. The main spring is supported on the lower template through the multiple support components. A positioning post is installed on the positioning component. The positioning post passes through the main spring.

[0007] Compared with existing technologies, the advantages of this application are that the front side of the mounting plate is equipped with multiple pin seats according to the through holes on the support arm, and the front side of the pin seats is equipped with positioning pins, which can achieve precise mounting of the support arm and the mounting plate. This design ensures the accuracy of the support arm's position during installation, providing a basic guarantee for subsequent press-fitting operations and effectively avoiding press-fitting problems caused by initial position deviations. The rotating pressure head assembly on the mounting plate can press the support arm into the pin seats, preventing the support arm from shifting or tilting during press-fitting. Through the pressing action of the rotating pressure head assembly, the stability of the support arm during the press-fitting process is enhanced, the press-fitting accuracy is improved, and the overall performance and reliability of the shock absorber assembly are ensured.

[0008] The lower mounting base on the top surface of the lower template includes a positioning element and multiple regularly distributed support elements. The positioning pins on the positioning element pass through the main spring, providing precise positioning and ensuring the accuracy of the main spring's position during the pressing process. Simultaneously, the regularly distributed support elements evenly support the main spring, preventing deformation or displacement during pressing and ensuring pressing quality.

[0009] The entire equipment is designed to fully consider the actual needs of shock absorber assembly press-fitting. Through the cooperation of the upper and lower templates, as well as the coordinated work of the mounting plate, rotating pressure head assembly, and lower mounting base, efficient press-fitting of the support arm and main spring assembly is achieved. This reasonable structural design can effectively improve press-fitting efficiency, reduce press-fitting failures caused by unreasonable equipment structure, and improve production efficiency.

[0010] In some embodiments of this application, the top surface of the positioning member is provided with a slot, the positioning post is installed in the slot, and a spring is installed at the bottom of the positioning post. The spring drives the upper part of the positioning post to extend out of the positioning member. When the positioning post is subjected to force, it moves downward and embeds into the slot. The downward-moving positioning post compresses the spring.

[0011] The positioning column is automatically extended and retracted by the spring, which can realize the positioning of the main spring during installation. When the support arm is pressed down, the positioning column can avoid the force, so that the support arm and the main spring can be pressed smoothly.

[0012] In some embodiments of this application, the bottom surface of the support arm faces the slot hole, and the operation of the press drives the support arm installed at the upper template to move downward, and the downward-moving support arm presses down the positioning column.

[0013] The elastic connection structure of the positioning column not only avoids force distribution, allowing both the support arm and the main spring to be press-fitted smoothly, but also effectively prevents the main spring from loosening or shifting due to impact during the press-fitting process, thus improving press-fitting accuracy and quality.

[0014] In some embodiments of this application, a proximity switch is provided on the lower template.

[0015] By using proximity switches to automatically detect the installation status of the main spring, it is possible to quickly and accurately determine whether the main spring is installed in place. This avoids products that are not properly assembled due to human inspection errors from entering subsequent processes, thereby improving the stability of product quality and reducing the defect rate and rework costs.

[0016] In some embodiments of this application, the positioning pin is arranged parallel to the upper template, and the support arm is hung from front to back on the front side of the mounting plate, with the positioning pin inserted into the through hole of the support arm. This ensures accurate positioning of the support arm, avoids assembly problems caused by positional deviations during installation, and improves the accuracy and reliability of assembly.

[0017] For ease of description, this application uses the accompanying drawings as an example. Figure 1 The description is based on the principle of "front side" (the side closer to the manual operation) and "rear side" (the side farther from the manual operation).

[0018] In some embodiments of this application, the rotary pressure head assembly includes a rotary cylinder, a clamping arm, and a pressure head. One end of the clamping arm is connected to the output shaft of the rotary cylinder, and the other end of the clamping arm is equipped with a pressure head. The rotary cylinder drives the clamping arm to rotate, and the rotated pressure head acts on the support arm. The rotated pressure head is opposite to one of the pin seats.

[0019] The rotary pressure head assembly drives the clamping arm to rotate via a rotary cylinder, enabling the pressure head to precisely act on the support arm and press it against the pin seat. This achieves automated clamping and fixing of the support arm, avoiding the instability of manual clamping, improving the stability of the support arm during the pressing process, and ensuring the consistency of pressing quality.

[0020] In some embodiments of this application, a first sensor is installed below the upper template, and the first sensor is set corresponding to the support arm. The first sensor is a laser rangefinder sensor.

[0021] The first sensor is used to detect whether the outrigger is properly installed on the mounting plate. Utilizing a laser rangefinder sensor to automatically detect the outrigger's installation position allows for quick and accurate determination of whether it is installed correctly, avoiding installation errors caused by human factors. This improves the accuracy and efficiency of the detection, thereby ensuring the smooth progress of the subsequent pressing process and the stability of product quality.

[0022] In some embodiments of this application, a second sensor is installed above the lower template, and the second sensor is disposed on the top surface of the main spring. The second sensor is a laser rangefinder.

[0023] The second sensor is used to detect whether the support arm has been pressed down to the position where it is pressed into place with the main spring. The laser rangefinder automatically detects whether the support arm is pressed into place, ensuring reliable pressing between the support arm and the main spring, avoiding problems caused by incomplete pressing, improving the stability and reliability of pressing quality, and reducing the defect rate.

[0024] In some embodiments of this application, oil-free bushings are provided at the four corners of the top surface of the lower template, and guide shafts are provided at the four corners of the bottom surface of the upper template. The guide shafts correspond one-to-one with the oil-free bushings, and the bottom of the guide shafts is inserted into the oil-free bushings. When the lower template is pressed down, the guide shafts move along the axial direction of the oil-free bushings.

[0025] The oil-free bushing and guide shaft work together to ensure precise alignment and smooth movement of the upper and lower templates during the pressing process, reducing friction and wear between the templates. It also prevents template misalignment from affecting pressing accuracy, thus improving the service life of the equipment and the stability of pressing quality.

[0034] The present application will now be described in detail with reference to the accompanying drawings.

[0035] 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.

[0036] Shock absorber assembly press-fitting equipment, Example 1, as follows Figures 1 to 3 As shown: The machine includes an upper template 1 and a lower template 2 connected to the press 11. A mounting plate 3 is fixed below the upper template 1, and the mounting plate 3 is perpendicular to the upper template 1. Multiple pin seats 4 are provided on the front side of the mounting plate 3 corresponding to the through holes on the support arm 12. Positioning pins 5 are provided on the front side of the pin seats 4. The support arm 12 is hung on the front side of the mounting plate 3 via the positioning pins 5, enabling precise mounting of the support arm 12 and the mounting plate 3. This design ensures the accuracy of the support arm 12's position during installation, providing a basic guarantee for subsequent pressing operations and effectively avoiding pressing problems caused by initial positional deviations.

[0037] The mounting plate 3 is equipped with a rotating pressure head assembly 6. The rotating pressure head assembly 6 presses the support arm 12 into the pin seat 4, preventing the support arm 12 from shifting or tilting during pressing. The pressing action of the rotating pressure head assembly 6 enhances the stability of the support arm 12 during the pressing process, improves the pressing accuracy, and ensures the overall performance and reliability of the shock absorber assembly.

[0038] The lower template 2 has a lower mounting base 7 on its top surface. The lower mounting base 7 includes a positioning element 8 and multiple support elements 9 regularly distributed on the lower template 2. The main spring 13 is supported on the lower template 2 by the multiple support elements 9. A positioning post 10 is installed on the positioning element 8, and the positioning post 10 passes through the main spring 13. This provides precise positioning for the main spring 13, ensuring the accuracy of its position during the pressing process. At the same time, the regular distribution of the multiple support elements 9 can evenly support the main spring 13, preventing deformation or displacement of the main spring 13 during the pressing process and ensuring the pressing quality.

[0039] The entire equipment is designed to fully consider the actual needs of shock absorber assembly press-fitting. Through the cooperation of the upper template 1 and the lower template 2, as well as the coordinated work of the mounting plate 3, the rotating pressure head assembly 6, and the lower mounting base 7, efficient press-fitting of the support arm 12 and the main spring 13 assembly is achieved. This structural design is reasonable and can effectively improve press-fitting efficiency, reduce press-fitting failures caused by unreasonable equipment structure, and improve production efficiency.

[0040] For ease of description, this application uses the accompanying drawings as an example. Figure 1 The description is based on the principle of "front side" (the side closer to the manual operation) and "rear side" (the side farther from the manual operation).

[0041] Example 2, as Figures 1 to 5 As shown, the top surface of the positioning member 8 has a slot, and the positioning post 10 is installed in the slot. A spring is installed at the bottom of the positioning post 10. The spring drives the upper part of the positioning post 10 to extend out of the positioning member 8. When the positioning post 10 is subjected to force, it moves downward and embeds into the slot. The downward movement of the positioning post 10 compresses the spring. By automatically extending and retracting the positioning post 10 driven by the spring, the positioning of the main spring 13 can be achieved during installation. When the support arm 12 is pressed downward, the positioning post 10 can avoid the force, so that both the support arm 12 and the main spring 13 can be pressed smoothly.

[0042] The bottom surface of the support arm 12 faces the slot. When the press 11 operates, it drives the support arm 12, which is installed on the upper template 1, to move downwards. The downward-moving support arm 12 presses down on the positioning post 10. The elastic connection structure of the positioning post 10 can both avoid force, allowing the support arm 12 and the main spring 13 to be pressed smoothly. It can also effectively prevent the main spring 13 from loosening or shifting due to impact during the pressing process, thus improving the pressing accuracy and quality.

[0043] A proximity switch 14 is provided on the lower template 2. The proximity switch 14 automatically detects the installation status of the main spring 13, which can quickly and accurately determine whether the main spring 13 is installed in place. This avoids products that are not properly assembled due to human inspection errors from entering subsequent processes, thereby improving the stability of product quality and reducing the defect rate and rework costs.

[0044] The positioning pin 5 is set parallel to the upper template 1, and the support arm 12 is hung from front to back on the front side of the mounting plate 3. The positioning pin 5 is inserted into the through hole of the support arm 12. This ensures the accurate positioning of the support arm 12, avoids assembly problems caused by positional deviations during the installation process, and improves the accuracy and reliability of the assembly.

[0045] The rotary pressing head assembly 6 includes a rotary cylinder 15, a clamping arm 16, and a pressing head 17. One end of the clamping arm 16 is connected to the output shaft of the rotary cylinder 15, and the pressing head 17 is mounted on the other end of the clamping arm 16. The rotary cylinder 15 drives the clamping arm 16 to rotate, and the rotated pressing head 17 acts on the support arm, and the rotated pressing head 17 is opposite to one of the pin seats 4. The rotary pressing head assembly 6 drives the clamping arm 16 to rotate through the rotary cylinder 15, so that the pressing head 17 can accurately act on the support arm 12 and press it against the pin seat 4, realizing the automated clamping and fixing of the support arm 12, avoiding the instability of manual clamping, improving the stability of the support arm 12 during the pressing process, and ensuring the consistency of the pressing quality.

[0046] A first sensor 18 is installed below the upper template 1, corresponding to the support arm 12. The first sensor 18 is a laser rangefinder. The first sensor 18 is used to detect whether the support arm 12 is properly installed at the mounting plate 3. By automatically detecting the installation position of the support arm 12 using a laser rangefinder, it is possible to quickly and accurately determine whether the support arm 12 is properly installed, avoiding installation errors caused by human factors. This improves the accuracy and efficiency of the detection, thereby ensuring the smooth progress of the subsequent pressing process and the stability of product quality.

[0047] A second sensor 19 is installed above the lower template 2, corresponding to the top surface of the main spring 13. The second sensor 19 is a laser rangefinder. The second sensor 19 is used to detect whether the support arm 12 has been pressed down to the position where it is pressed into place with the main spring 13. By automatically detecting whether the support arm 12 is pressed into place using the laser rangefinder, reliable pressing between the support arm 12 and the main spring 13 is ensured, avoiding problems caused by incomplete pressing, improving the stability and reliability of the pressing quality, and reducing the defect rate.

[0048] Oil-free bushings 20 are provided at the four corners of the top surface of the lower template 2, and guide shafts 21 are provided at the four corners of the bottom surface of the upper template 1. Each guide shaft 21 corresponds to one of the oil-free bushings 20, with the bottom of the guide shaft 21 inserted into the oil-free bushing 20. When the lower template 2 is pressed down, the guide shafts 21 move axially along the oil-free bushings 20. The cooperation between the oil-free bushings 20 and the guide shafts 21 ensures precise alignment and smooth movement of the upper template 1 and lower template 2 during the pressing process, reduces friction and wear between the templates, and prevents pressing accuracy from being affected by template misalignment, thereby improving the service life of the equipment and the stability of the pressing quality.

[0049] The rest of the contents of Example 2 are the same as those of Example 1.

The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
