Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, and in particular to an automotive torsion frame press sleeve device. Background Technology

[0002] With the booming development of the automotive industry, the manufacturing technology of automotive parts is also constantly evolving. As one of the key components of the automotive chassis, the refinement of the assembly process of the torsion frame is of paramount importance to improving the overall quality of the vehicle. Among the many assembly stages, the bushing pressing process has always been a key factor restricting production efficiency and product quality.

[0003] Related prior art, such as the Chinese patent application "Single-station bidirectional automated bushing pressing device for automotive torsion beams," application number: CN202510250140.2, discloses a single-station bidirectional automated bushing pressing device for automotive torsion beams, including a middle plate, a torsion beam support mechanism, a torsion beam positioning mechanism, and a bushing pressing mechanism. The bushing pressing mechanism includes a bushing drive unit and a bushing positioning support unit. The drive component of the bushing drive unit and the first positioning mandrel of the bushing positioning support unit are respectively located on the outer and inner sides of the mounting sleeve of the torsion beam. The first positioning mandrel is slidably supported on the middle plate and moved towards the mounting sleeve by the drive component. This invention overcomes the shortcomings of the prior art, has a reasonable design, and provides fast pressing, solving the technical problems of low pressing efficiency and poor reliability of existing bushing pressing devices.

[0004] The bushing surface involved in this application is made of plastic. This structural feature makes the bushing surface susceptible to scratches, wear, and localized deformation during the press-fitting process, affecting not only the appearance quality of the bushing but also its performance. Existing equipment, failing to consider the special characteristics of the bushing, cannot provide effective protection for the bushing surface during the press-fitting process and cannot meet the increasingly stringent standards for component assembly quality in the current automotive manufacturing industry. Utility Model Content

[0005] The technical problem to be solved by this application is to provide an automotive torsion frame pressing device that effectively protects the bushing and ensures the coaxiality and positional accuracy of the pressing.

[0006] The technical solution adopted in this application is as follows: an automotive torsion frame pressing device, including a base plate, a frame mounting seat on the base plate, pressing devices at both ends of the frame mounting seat, a torsion frame mounted on the frame mounting seat, and the assembly end of the torsion frame extending into the pressing device; the pressing device includes a base, a positioning post, a support seat, and a conforming pressing sleeve, the support seat is provided on the base, the conforming pressing sleeve is mounted on the base through the support seat, the positioning post is installed in the conforming pressing sleeve, the positioning post is mounted on the base through a floating component, the positioning post is inserted into a bushing, the bushing is located in the conforming pressing sleeve, and the inner wall surface of the conforming pressing sleeve is adapted to the assembly end of the torsion frame.

[0007] Compared with the prior art, the advantages of this application are that the positioning post is installed in the conformal compression sleeve and mounted on the base through a floating component. It can make certain floating adjustments according to the position and shape of the bushing, ensuring that the positioning post is accurately inserted into the bushing, achieving precise positioning of the bushing, improving the coaxiality and positional accuracy during the pressing process, and playing a key role in ensuring a good fit between the bushing and the torsion frame assembly end.

[0008] The inner wall of the contour-following bushing is adapted to the assembly end of the torsion frame. This shape adaptation provides excellent guidance for the assembly end of the torsion frame, guiding the pressing device to accurately align with the assembly end. Simultaneously, it effectively limits the assembly end during pressing, preventing displacement or wobbling under pressing force, further improving the stability of the pressing quality. Since the bushing surface is made of plastic, it is prone to scratches, wear, and localized deformation during pressing. The contour-following bushing effectively isolates the bushing from other components of the pressing device, reducing direct contact and friction between other components and the bushing surface during pressing. This lowers the risk of bushing surface damage, helps protect the bushing's appearance quality and performance, and meets the stringent standards of the automotive manufacturing industry for component assembly quality.

[0009] As the basic support structure of the entire equipment, the base plate provides a stable installation platform for the frame mounting seat, ensuring the stable placement of the torsion frame during the pressing process, effectively reducing assembly errors caused by equipment shaking, and ensuring assembly accuracy.

[0010] In some embodiments of this application, the base has an L-shaped structure, the base includes a horizontal plate and a vertical plate, the conforming pressure sleeve is installed on the horizontal plate, a support seat is provided between the conforming pressure sleeve and the horizontal plate, and the positioning column is installed on the vertical plate by a floating component.

[0011] The horizontal plate provides a stable installation platform for the conformal compression sleeve, and the support between the compression sleeve and the horizontal plate further enhances the stability of the installation, ensuring that the compression sleeve will not shake or deform during the pressing process. Positioning posts are installed at the vertical plate and connected by floating components, allowing the positioning posts to be flexibly adjusted according to the position of the bushing, ensuring positioning accuracy. At the same time, the L-shaped structure as a whole improves the rigidity and stability of the pressing device, contributing to improved pressing quality.

[0012] In some embodiments of this application, one end of the positioning post faces the opening side of the conforming pressure sleeve, and the other end of the positioning post is mounted on the front fixed plate. The front fixed plate is connected to the floating component, and the conforming pressure sleeve is sleeved outside the front fixed plate. The outer diameter of the front fixed plate is adapted to the inner diameter of the conforming pressure sleeve. The positioning post, the front fixed plate, and the conforming pressure sleeve are coaxially arranged.

[0013] This coaxial arrangement ensures precise geometric alignment of the positioning post, front fixing plate, and conformal compression sleeve. The positioning post faces the opening of the conformal compression sleeve, facilitating insertion into the bushing and enabling rapid positioning. The front fixing plate connects to a floating assembly, giving the entire positioning system a degree of buoyancy to accommodate bushing positional deviations and ensure accurate insertion of the positioning post. Simultaneously, the coaxial arrangement improves coaxiality during press-fitting, helping to ensure a good fit between the bushing and the torsion frame assembly end, reducing assembly stress and the risk of bushing deformation.

[0014] In some embodiments of this application, the pressing device includes a middle plate, an upper plate, and a power cylinder. A slider is mounted on the middle plate and fixed above the middle plate. The base is mounted on the upper plate and fixedly connected to the upper plate. A slide rail is provided on the lower surface of the upper plate. The slider is installed below the slide rail. The power cylinder is connected to the upper plate. The operation of the power cylinder drives the upper plate to move relative to the middle plate along the slide rail direction.

[0015] The cooperation between the slide rail and the slider allows the upper plate to move smoothly along the slide rail. The power cylinder drives the upper plate to move the base and the entire pressing device to perform precise pressing actions. This structure realizes automated movement and precise pressing of the pressing device, improving pressing efficiency and accuracy. At the same time, the slider is fixed above the middle plate, providing stable support and guidance for the entire pressing device, ensuring the smoothness and reliability of the pressing process.

[0016] In some embodiments of this application, two blocks are respectively provided on the middle plate, and the two blocks are respectively located on both sides of the slide rail. A front buffer and a rear buffer are provided on both sides of the upper plate. The blocks are located between the front buffer and the rear buffer, and the front buffer and the rear buffer are both facing the blocks.

[0017] The stop blocks and buffers effectively protect the slide rail from excessive impact at both ends. When the current fixed plate moves to both ends of the slide rail, the front and rear buffers contact the stop blocks, providing a buffering effect and reducing the impact force when the equipment is at its extreme positions. This extends the service life of the equipment, reduces wear and the risk of failure, and ensures the smooth and safe operation of the pressing device.

[0018] In some embodiments of this application, the pressing device further includes a base plate, which is fixed on a base plate, and a sliding assembly is provided between the base plate and the middle plate, the sliding assembly being perpendicular to the slide rail.

[0019] The base plate and sliding assembly provide additional lateral movement capability for the press-fitting device. The base plate, fixed to the base plate, stabilizes the mounting foundation of the entire press-fitting device. The sliding assembly, perpendicular to the slide rail, allows the press-fitting device to move not only along the slide rail but also to be adjusted laterally, increasing its flexibility and adaptability, and facilitating press-fitting operations on torsion frames in different positions.

[0020] In some embodiments of this application, the frame mounting base includes two sets of support components, which are symmetrically arranged on the left and right sides and are located close to the pressing device.

[0021] The symmetrically arranged support components provide even support to the torsion frame, ensuring its stability during press-fitting. This symmetrical design helps balance the forces acting on the torsion frame during press-fitting, preventing it from tilting or twisting, thereby improving assembly accuracy and quality.

[0022] In some embodiments of this application, the support assembly includes regularly distributed inner support columns and rear mounting columns; the inner support columns are provided with pin seats, the pin seats are provided with pins, the rear mounting columns are provided with support blocks, the torsion frame is mounted on the support blocks and pin seats, and the pins are inserted into the torsion frame.

[0023] The regular distribution of the internal support columns and rear mounting columns effectively distributes the weight of the torsion frame, ensuring its stability. The pins on the pin holders insert into the torsion frame, effectively fixing its position and preventing displacement during press-fitting. The support blocks provide support for the lower part of the torsion frame, working together with the pin holders to ensure the stability and accuracy of the torsion frame during press-fitting.

[0024] In some embodiments of this application, both the inner support column and the rear mounting column are provided with adjustment blocks, the support block is mounted on the adjustment block, a removable shim is provided between the support block and the adjustment block, the pin seat is mounted on the adjustment block, and a removable shim is provided between the pin seat and the adjustment block.

[0025] The design of the adjusting block and removable shims provides flexible adjustment capabilities. By increasing or decreasing the number or thickness of the shims, the height of the support block and pin seat can be precisely adjusted to accommodate different specifications of torsion frames, achieving accurate positioning and support of the torsion frame. This design improves the versatility and adaptability of the equipment, facilitating press-fitting operations on different models of torsion frames.

[0026] In some embodiments of this application, a quick clamp is provided on the rear mounting post, and the downward pressure of the quick clamp acts on the torsion beam located on the pin seat; a plurality of auxiliary guide tubes are also provided on the base plate, and the top of the auxiliary guide tubes is bent.

[0027] The quick-release clamps enable rapid securing and releasing of the torsion beam, improving operational convenience and efficiency. The auxiliary guide tube provides guidance for the installation of the torsion frame, allowing it to be smoothly installed onto the support assembly, reducing installation difficulties and time, and improving the overall efficiency and convenience of the assembly process.

[0036] The present application will now be described in detail with reference to the accompanying drawings.

[0037] 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.

[0038] Automotive torsion frame compression molding equipment, Example 1 as follows Figure 1 , Figure 2As shown: The device includes a base plate 1, on which a frame mounting base 2 is mounted. Press-fitting devices 3 are located at both ends of the frame mounting base 2. A torsion frame 23 is mounted on the frame mounting base 2, with its assembly end extending into the press-fitting device 3. The press-fitting device 3 includes a base 4, a positioning post 5, a support seat 6, and a contoured pressing sleeve 7. The support seat 6 is mounted on the base 4, and the contoured pressing sleeve 7 is mounted on the base 4 via the support seat 6. The positioning post 5 is installed inside the contoured pressing sleeve 7 and is mounted on the base 4 via a floating component 8. The positioning post 5 is inserted into a bushing 9, which is located within the contoured pressing sleeve 7. This allows for a certain degree of floating adjustment based on the position and shape of the bushing 9, ensuring accurate insertion of the positioning post 5 into the bushing 9. This achieves precise positioning of the bushing 9, improving coaxiality and positional accuracy during the press-fitting process. This plays a crucial role in ensuring a good fit between the bushing 9 and the assembly end of the torsion frame 23.

[0039] The inner wall surface of the contoured pressure sleeve 7 is adapted to the assembly end of the torsion frame 23. This shape adaptation provides good guidance for the assembly end of the torsion frame 23, guiding the pressing device 3 to accurately align with the assembly end of the torsion frame 23. Simultaneously, it effectively limits the assembly end during pressing, preventing it from shifting or wobbling under pressing force, further improving the stability of the pressing quality. Since the surface of the bushing 9 is made of plastic, it is prone to scratches, wear, and localized deformation during pressing. The presence of the contoured pressure sleeve 7 effectively isolates the bushing 9 from other components of the pressing device 3, reducing direct contact and friction between other components and the surface of the bushing 9 during pressing. This reduces the risk of surface damage to the bushing 9, protecting its appearance quality and performance, and meeting the stringent standards of the automotive manufacturing industry for component assembly quality.

[0040] The base plate 1 serves as the basic support structure for the entire equipment, providing a stable mounting platform for the frame mounting seat 2. This ensures the stable placement of the torsion frame 23 during the pressing process, effectively reducing assembly errors caused by equipment shaking and guaranteeing assembly accuracy.

[0041] Example 2, as Figures 1 to 5 As shown, the base 4 has an L-shaped structure and includes a horizontal plate 10 and a vertical plate 11. The conformal pressing sleeve 7 is mounted on the horizontal plate 10, and a support seat 6 is provided between the conformal pressing sleeve 7 and the horizontal plate 10. The positioning post 5 is mounted on the vertical plate 11 via a floating component 8. The horizontal plate 10 provides a stable mounting platform for the conformal pressing sleeve 7, and the support seat 6 between the conformal pressing sleeve 7 and the horizontal plate 10 further enhances the stability of the installation, ensuring that the conformal pressing sleeve 7 will not shake or deform during the pressing process. The positioning post 5 is installed on the vertical plate 11 and connected by the floating component 8, allowing the positioning post 5 to be flexibly adjusted according to the position of the bushing 9, ensuring positioning accuracy. At the same time, the L-shaped structure as a whole improves the rigidity and stability of the pressing device 3, which helps to improve the pressing quality.

[0042] One end of the positioning post 5 faces the opening side of the conformal compression sleeve 7, and the other end of the positioning post 5 is mounted on the front fixed plate 12. The front fixed plate 12 is connected to the floating component 8, and the conformal compression sleeve 7 is fitted over the front fixed plate 12. The outer diameter of the front fixed plate 12 is adapted to the inner diameter of the conformal compression sleeve 7. The positioning post 5, the front fixed plate 12, and the conformal compression sleeve 7 are coaxially arranged. This coaxial arrangement ensures precise geometric alignment of the positioning post 5, the front fixed plate 12, and the conformal compression sleeve 7. The positioning post 5 faces the opening side of the conformal compression sleeve 7, which facilitates insertion into the bushing 9 and achieves rapid positioning. The connection between the front fixed plate 12 and the floating component 8 gives the entire positioning system a certain floating capability, which can adapt to the positional deviation of the bushing 9 and ensure that the positioning post 5 is accurately inserted into the bushing 9. At the same time, the coaxial arrangement improves the coaxiality during the pressing process, which helps to ensure a good fit between the bushing 9 and the assembly end of the torsion frame 23, and reduces the assembly stress and the risk of deformation of the bushing 9.

[0043] The pressing device 3 includes a middle plate 13, an upper plate 14, and a power cylinder 15. A slider 16 is mounted on the middle plate 13 and fixed above it. A base 4 is mounted on the upper plate 14 and fixedly connected to it. A slide rail 17 is provided on the lower surface of the upper plate 14, and the slider 16 is installed below the slide rail 17. The power cylinder 15 is connected to the upper plate 14, and its operation drives the upper plate 14 to move relative to the middle plate 13 along the slide rail 17. The cooperation of the slide rail 17 and the slider 16 allows the upper plate 14 to move smoothly along the slide rail 17. The power cylinder 15 drives the upper plate 14 to move the base 4 and the entire pressing device 3 to perform precise pressing actions. This structure realizes automated movement and precise pressing of the pressing device 3, improving pressing efficiency and accuracy. At the same time, the slider 16, fixed above the middle plate 13, provides stable support and guidance for the entire pressing device 3, ensuring the stability and reliability of the pressing process.

[0044] Two stops 18 are respectively provided on the middle plate 13, located on both sides of the slide rail 17. A front buffer 19 and a rear buffer 20 are provided on both sides of the upper plate 14. The stops 18 are located between the front buffer 19 and the rear buffer 20, with both the front buffer 19 and the rear buffer 20 facing the stops 18. The stops 18 and buffers effectively protect the slide rail 17 from excessive impact at both ends. When the fixed plate 12 moves to both ends of the slide rail 17, the front buffer 19 and the rear buffer 20 contact the stops 18, providing a buffering effect and reducing the impact force at extreme positions, thereby extending the service life of the equipment, reducing wear and the risk of failure, and ensuring the smooth and safe operation of the pressing device 3.

[0045] The pressing device 3 also includes a base plate 21, which is fixed to the base plate 1. A sliding assembly 22 is provided between the base plate 21 and the middle plate 13, and the sliding assembly 22 is perpendicular to the slide rail 17. The arrangement of the base plate 21 and the sliding assembly 22 provides the pressing device 3 with additional lateral movement capability. The base plate 21, fixed to the base plate 1, stabilizes the mounting foundation of the entire pressing device 3. The sliding assembly 22, being perpendicular to the slide rail 17, allows the pressing device 3 to move not only along the slide rail 17 but also to be adjusted laterally, increasing the flexibility and adaptability of the pressing device 3 and facilitating pressing operations on the torsion frame 23 at different positions.

[0046] The rest of the contents of Example 2 are the same as those of Example 1.

[0047] Example 3, as Figures 1 to 3 The frame mounting base 2 includes two sets of support components, which are symmetrically arranged on the left and right sides and positioned close to the pressing device 3. The symmetrically arranged support components can evenly support the torsion frame 23, ensuring its stability during the pressing process. This symmetrical design helps balance the forces acting on the torsion frame 23 during pressing, preventing it from tilting or twisting, thereby improving assembly accuracy and quality.

[0048] The support assembly includes regularly distributed inner support columns 24 and rear mounting columns 25. The inner support columns 24 are equipped with pin seats 26, and pins 27 are mounted on the pin seats 26. The rear mounting columns 25 are equipped with support blocks 28. A torsion frame 23 is mounted on the support blocks 28 and pin seats 26, with the pins 27 inserted into the torsion frame 23. The regular distribution of the inner support columns 24 and rear mounting columns 25 effectively distributes the weight of the torsion frame 23, ensuring the stability of the support. The pins 27 on the pin seats 26, inserted into the torsion frame 23, effectively fix the position of the torsion frame 23, preventing displacement during press-fitting. The support blocks 28 provide support for the lower part of the torsion frame 23, working together with the pin seats 26 to ensure the stability and accuracy of the torsion frame 23 during press-fitting.

[0049] Both the inner support column 24 and the rear mounting column 25 are equipped with adjusting blocks 29. Support blocks 28 are mounted on the adjusting blocks 29, and removable shims are provided between the support blocks 28 and the adjusting blocks 29. Pin seats 26 are mounted on the adjusting blocks 29, and removable shims are provided between the pin seats 26 and the adjusting blocks 29. The design of the adjusting blocks 29 and the removable shims provides flexible adjustment functionality. By increasing or decreasing the number or thickness of the shims, the height of the support blocks 28 and the pin seats 26 can be precisely adjusted, thereby adapting to different specifications of the torque frame 23 and achieving precise positioning and support of the torque frame 23. This design improves the versatility and adaptability of the equipment, facilitating press-fitting operations on different models of torque frames 23.

[0050] The rear mounting post 25 is equipped with a quick-release clamp 30. When the quick-release clamp 30 presses down, it acts on the torsion beam located on the pin seat 26. The base plate 1 is also equipped with several auxiliary guide tubes 31, the tops of which are bent. The quick-release clamp 30 allows for rapid fixing and release of the torsion beam, improving the convenience and efficiency of operation. The auxiliary guide tubes 31 provide guidance for the installation of the torsion frame 23, enabling it to be smoothly installed onto the support assembly, reducing difficulties and time during installation, and improving the efficiency and convenience of the entire assembly process.
