Abstract
Description
Technical Field
[0001] This application relates to the field of automotive parts manufacturing technology, and in particular to a lifting mechanism for a press. Background Technology
[0002] In the modern automotive industry, shock absorbers play a crucial role. Their primary function is to suppress vibrations and swaying caused by road bumps, braking, and acceleration during driving, thereby ensuring vehicle stability, comfort, and handling performance. Automotive shock absorbers are typically installed in the vehicle's suspension system, using internal mechanical structures and hydraulic systems to absorb and buffer vibration energy, thus reducing the feeling of bumps and the impact of vibrations on the vehicle body and components.
[0003] In the production and processing of shock absorbers, a press-fitting process is involved. Relevant existing technologies, such as the Chinese patent application "A Shock Absorber Press-fitting Machine" (application number: CN201410388891.2), disclose a machine comprising: a shock absorber positioning and changing mechanism, an upper centering mechanism, a servo press-fitting mechanism, an automatic tightening mechanism, an elbow clamping mechanism, a servo positioning mechanism, a frame, and a control system. The shock absorber positioning and changing mechanism is used to accommodate different types of shock absorbers. The upper centering mechanism is used to clamp the shock absorber cap for centering after the shock absorber column is fixed by the shock absorber positioning and changing mechanism, so that the axis of the shock absorber column remains concentric with the hole in the shock absorber cap. The servo... The machine includes a pressing mechanism for determining the pressing height based on the type of the shock absorber column, and then pressing the spring nested on the shock absorber column; an elbow clamping mechanism for clamping the shock absorber column to keep its position unchanged during the pressing of the spring; a servo positioning mechanism for adjusting the height of the upper centering mechanism based on the type of the shock absorber column; an automatic tightening mechanism for selecting the corresponding torque based on the type of the shock absorber column and tightening the nut into the shock absorber column by servo control of the torque; a control system for controlling the movement of each component of the shock absorber pressing machine; and a frame for mounting each component of the shock absorber pressing machine.
[0004] However, if the pressing force required for the vibration damper is large, the press must have a sufficiently large output force while ensuring the stability and accuracy of the pressing process. Therefore, the stability of the bottom worktable or fixture is extremely important to ensure it can withstand the entire pressing reaction force without deformation or displacement. This necessitates that the entire frame structure of the equipment possess very high rigidity. To meet the high rigidity requirements of the equipment, existing pressing equipment typically employs a large, heavy frame structure. This structure not only makes the equipment itself bulky but also requires a significant amount of space in the workshop, hindering the utilization of factory space and the flexibility of equipment layout.
[0005] To address the aforementioned problems, this application proposes a lifting mechanism for a press. This lifting mechanism bears the pressure of the press. This effectively reduces the rigidity requirements of the equipment frame, thereby reducing the equipment's size and floor space, and improving its practicality and economy. Utility Model Content
[0006] The technical problem to be solved by this application is to provide a lifting mechanism for a press that optimizes the transmission and distribution of force, reduces the rigidity requirements and floor space of the equipment, and has high practicality and economy.
[0007] The technical solution adopted in this application is as follows: a lifting mechanism for a press, including a mounting base plate, both sides of the mounting base plate forming mounting surfaces, a longitudinal slide rail provided on at least one mounting surface, a slider mounted on the longitudinal slide rail, a mounting seat connected above the slider, a reference seat provided below the longitudinal slide rail, a power cylinder movably provided on one side of the longitudinal slide rail, the output shaft of the power cylinder being hinged to one end of a first connecting member and one end of a second connecting member, the other end of the first connecting member being hinged to the slider, and the other end of the second connecting member being hinged to the reference seat.
[0008] Compared with the prior art, the advantages of this application are as follows: First, the power cylinder is located on one side of the longitudinal slide rail, and its output shaft is hinged to the first and second connecting parts. This structure allows the power cylinder to effectively transmit power to the slider. Through the lever effect of the connecting parts, the output force of the power cylinder can be amplified, thereby achieving a larger lifting force with a smaller power cylinder output force, meeting the larger pressing force requirements for the damper pressing.
[0009] Secondly, the first and second connecting parts not only transmit power but also distribute the output force of the power cylinder rationally to the slider and the reference seat. This force distribution method allows the entire mechanism to better disperse stress when subjected to large pressing reaction forces, avoiding excessive local stress that could damage the equipment and improving its reliability and service life. The reference seat is located below the longitudinal slide rail, providing a stable support foundation for the entire mechanism. The power cylinder is hinged to the slider and the reference seat through the first and second connecting parts. This structure allows the power cylinder's power to be transmitted smoothly and efficiently to the slider, thereby driving the mounting base to rise or fall and ensuring the stability of the lifting process.
[0010] Secondly, traditional pressing equipment requires large, heavy frame structures to meet high rigidity requirements. However, this lifting mechanism, by bearing the pressure of the press itself, significantly reduces the rigidity requirements of the equipment frame. This means the equipment frame can be designed to be lighter, reducing material usage and lowering equipment costs. Due to the compact design of this lifting mechanism, the overall size of the press is reduced, thus occupying less space in the workshop. This improves factory space utilization, allows for more flexible equipment layout, and enables companies to rationally arrange equipment positions within the workshop according to production needs, thereby improving production efficiency.
[0011] In some embodiments of this application, a mounting base is provided on one side of the longitudinal slide rail, and the end of the power cylinder away from the output shaft is rotatably connected to the mounting base via a rotating shaft. When the power cylinder is subjected to force, it rotates around the rotating shaft. This rotatable connection design allows the power cylinder to automatically adjust its angle according to the movement trajectory of the slider during operation, thereby better adapting to the linear motion of the slider, reducing resistance and friction during movement, and improving the efficiency and stability of power transmission. Simultaneously, the rotatable connection can also avoid unnecessary stress concentration in the power cylinder when under force, extending the service life of the power cylinder.
[0012] In some embodiments of this application, the output shaft of the power cylinder is fixedly mounted with a main connecting member, and the main connecting member is provided with a main hinge point. Both the first connecting member and the second connecting member are hinged to the main hinge point. By designing the main connecting member and the main hinge point, the first and second connecting members are connected to a single point. This structure simplifies the power transmission path, allowing the output force of the power cylinder to be more evenly distributed across the two connecting members. Simultaneously, the main connecting member improves the stability and reliability of the connection, preventing power transmission failure due to loosening or misalignment.
[0013] In some embodiments of this application, the main connector has a main hinge interface, with the main hinge point located at the main hinge interface. One end of the first connector and one end of the second connector extend into the main hinge interface. This main hinge interface design allows the first and second connectors to connect more tightly to the main hinge point, enhancing the connection's robustness and stability. Simultaneously, this structural design effectively reduces the gap between the connectors, improving the accuracy and response speed of power transmission, and ensuring smoother and more precise movement of the slider.
[0014] In some embodiments of this application, the position where the first connecting member is hinged to the slider is designated as the first hinge point, and the position where the second connecting member is hinged to the reference seat is designated as the second hinge point, with the first hinge point located directly above the second hinge point. This vertically aligned hinge point layout allows the output force of the power cylinder to be transmitted more directly to the slider and reference seat through the connecting members, reducing the force transmission path and energy loss. Simultaneously, this layout helps maintain the symmetry and balance of the entire mechanism, further improving the stability and accuracy of the lifting process.
[0015] In some embodiments of this application, the first connector has an I-shaped structure, and the second connector has a Y-shaped structure, with one end of the second connector located at the main hinge interface extending into the first connector. This I-shaped first connector and Y-shaped second connector design provides the connectors with higher strength and stability when transmitting power. Furthermore, this structural design effectively reduces the volume and weight of the connectors, improving the overall compactness of the mechanism.
[0016] In some embodiments of this application, two parallel longitudinal slide rails are provided on the mounting surface. The slider is movably connected to the two longitudinal slide rails, and a connecting strip is provided in the middle of the slider, with its lower end extending outside the slider. The first hinge point is located at the lower end of the connecting strip. The two parallel longitudinal slide rails provide more stable guidance for the slider, ensuring that the slider always maintains linear motion during movement and reducing motion deviation. The design of the connecting strip makes the position of the first hinge point more stable, further improving the accuracy and reliability of power transmission. This structural design can effectively improve the stability and accuracy of the lifting process and ensure the pressing quality.
[0017] In some embodiments of this application, the main hinge point, the first hinge point, and the second hinge point form an isosceles triangle. This isosceles triangle design allows for a more even distribution of forces between the connecting components, reducing the risk of equipment damage due to force imbalance. Simultaneously, the symmetry of the isosceles triangle improves the stability and reliability of the entire mechanism, ensuring the smoothness and accuracy of the lifting process.
[0018] In some embodiments of this application, a limiting post is provided on one side of the reference base, and the limiting post is located below the second connecting member; a buffer post is provided on the side of the reference base facing the power cylinder, and the buffer post limits the movement limit position of the second connecting member.
[0019] The design of the limiting post restricts the movement trajectory of the second connecting member. Both the limiting post and the buffer post prevent the second connecting member from shifting or colliding during movement, thereby improving the operational safety and stability of the entire mechanism. The limiting post and the buffer post also act as a buffer, reducing the risk of equipment damage caused by impact.
[0020] In some embodiments of this application, sliders connected to power cylinders are provided on both mounting surfaces of the mounting base, and the two sliders are connected to the mounting seat. This allows the mounting seat to simultaneously receive the lifting force from the power cylinder through the two sliders, thereby achieving a more uniform force distribution and a more stable lifting effect. The dual-slider structure can improve the stability and reliability of the lifting process, reduce the risk of equipment damage caused by single-point force, and also better adapt to the pressing requirements of different specifications, improving the versatility of the equipment.
[0021] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0025] The present application will now be described in detail with reference to the accompanying drawings.
[0026] 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.
[0027] A lifting mechanism for a press, as described in Embodiment 1 Figure 1As shown: The system includes a mounting base 1, with two sides forming mounting surfaces. At least one mounting surface has a longitudinal slide rail 2, on which a slider 3 is mounted. A mounting base 4 is connected above the slider 3, and a reference base 5 is located below the longitudinal slide rail 2, providing a stable support foundation for the entire mechanism. A power cylinder 6 is movably mounted on one side of the longitudinal slide rail 2. The output shaft of the power cylinder 6 is hinged to one end of a first connecting member 7 and one end of a second connecting member 8. The other end of the first connecting member 7 is hinged to the slider 3, and the other end of the second connecting member 8 is hinged to the reference base 5. The power cylinder 6, positioned on one side of the longitudinal slide rail 2, with its output shaft hinged to the first connecting member 7 and the second connecting member 8, allows the power cylinder 6 to effectively transmit power to the slider 3. Through the lever action of the connecting members, the output force of the power cylinder 6 can be amplified, thereby achieving a larger lifting force with a smaller output force from the power cylinder 6, meeting the larger pressing force requirements for the vibration damper pressing.
[0028] Traditional pressing equipment requires large, heavy frame structures to meet high rigidity requirements. However, this lifting mechanism, by bearing the pressure of the press itself, significantly reduces the rigidity requirements of the equipment frame. This means the equipment frame can be designed to be lighter, reducing material usage and lowering equipment costs. Due to the compact design of this lifting mechanism, the overall size of the press is reduced, thus occupying less space in the workshop. This improves factory space utilization, allows for more flexible equipment layout, and enables companies to rationally arrange equipment positions within the workshop according to production needs, thereby improving production efficiency.
[0029] Preferably, each of the two mounting surfaces of the mounting base 1 is provided with a slider 3 connected to a power cylinder 6, and the two sliders 3 are connected to the mounting base 4. This allows the mounting base 4 to simultaneously receive the lifting force of the power cylinder 6 through the two sliders 3, thereby achieving a more uniform force distribution and a more stable lifting effect. The dual slider 3 structure can improve the stability and reliability of the lifting process, reduce the risk of equipment damage caused by single-point force, and also better adapt to the pressing requirements of different specifications, improving the versatility of the equipment.
[0030] Example 2, as Figures 1 to 3 As shown, a mounting base 9 is provided on one side of the longitudinal slide rail 2. The end of the power cylinder 6 away from the output shaft is rotatably connected to the mounting base 9 via a rotating shaft 10. When the power cylinder 6 is subjected to force, it rotates around the rotating shaft 10. This rotatable connection design allows the power cylinder 6 to automatically adjust its angle according to the movement trajectory of the slider 3 during operation, thereby better adapting to the linear movement of the slider 3, reducing resistance and friction during movement, and improving the efficiency and stability of power transmission. At the same time, the rotatable connection can also avoid unnecessary stress concentration in the power cylinder 6 when subjected to force, extending the service life of the power cylinder 6.
[0031] The output shaft of the power cylinder 6 is fixedly mounted with a main connecting member 11, and a main hinge point 12 is provided on the main connecting member 11. Both the first connecting member 7 and the second connecting member 8 are hinged to the main hinge point 12. Through the design of the main connecting member 11 and the main hinge point 12, the first connecting member 7 and the second connecting member 8 are connected to a single point. This structure simplifies the power transmission path, allowing the output force of the power cylinder 6 to be more evenly distributed to the two connecting members. Simultaneously, the main connecting member 11 improves the stability and reliability of the connection, preventing power transmission failure due to loosening or misalignment.
[0032] The main connector has a main hinge interface 13, and the main hinge point 12 is located at the main hinge interface 13. One end of the first connector 7 and one end of the second connector 8 extend into the main hinge interface 13. The design of the main hinge interface 13 allows the first connector 7 and the second connector 8 to connect more tightly to the main hinge point 12, enhancing the strength and stability of the connection. At the same time, this structural design can effectively reduce the gap between the connectors, improve the accuracy and response speed of power transmission, and ensure that the movement of the slider 3 is more stable and precise.
[0033] The position where the first connecting member 7 is hinged to the slider 3 is denoted as the first hinge point, and the position where the second connecting member 8 is hinged to the reference seat 5 is denoted as the second hinge point. The first hinge point is located directly above the second hinge point. This vertically aligned hinge point layout allows the output force of the power cylinder 6 to be transmitted more directly to the slider 3 and the reference seat 5 through the connecting members, reducing the force transmission path and energy loss. At the same time, this layout helps maintain the symmetry and balance of the entire mechanism, further improving the stability and accuracy of the lifting process.
[0034] The first connector 7 has an I-shaped structure, and the second connector 8 has a Y-shaped structure. One end of the second connector 8, located at the main hinge interface 13, extends into the first connector 7. The I-shaped first connector 7 and the Y-shaped second connector 8 design give the connectors higher strength and stability when transmitting power. Furthermore, this structural design effectively reduces the volume and weight of the connectors, improving the overall compactness of the mechanism.
[0035] Two parallel longitudinal slide rails 2 are provided on the mounting surface. The slider 3 is movably connected to the two longitudinal slide rails 2. A connecting bar 14 is provided in the middle of the slider 3, with its lower end extending outside the slider 3. The first hinge point is located at the lower end of the connecting bar 14. The two parallel longitudinal slide rails 2 provide more stable guidance for the slider 3, ensuring that the slider 3 always maintains linear motion during movement and reducing movement deviation. The design of the connecting bar 14 makes the position of the first hinge point more stable, further improving the accuracy and reliability of power transmission. This structural design can effectively improve the stability and accuracy of the lifting process and ensure the pressing quality.
[0036] The main hinge point 12, the first hinge point, and the second hinge point form an isosceles triangle. This isosceles triangle design ensures a more even distribution of forces between the connecting parts, reducing the risk of equipment damage due to force imbalances. Simultaneously, the symmetry of the isosceles triangle improves the stability and reliability of the entire mechanism, ensuring the smoothness and accuracy of the lifting process.
[0037] A limiting post 15 is provided on one side of the reference base 5, located below the second connecting member 8. A buffer post 16 is provided on the side of the reference base 5 facing the power cylinder 6, limiting the extreme positions of the movement of the second connecting member 8. The design of the limiting post 15 restricts the movement trajectory of the second connecting member 8. Both the limiting post 15 and the buffer post 16 can prevent the second connecting member 8 from deviating or colliding during movement, thereby improving the operational safety and stability of the entire mechanism. The limiting post 15 and the buffer post 16 also play a buffering role, reducing the risk of equipment damage caused by impact.
[0038] The rest of the contents of Example 2 are the same as those of Example 1.
[0039] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. 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.
