Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, and in particular to a spherical pressure head floating assembly. Background Technology

[0002] In the press-fitting and disassembly of bushings, the chassis, as a critical assembly base, inevitably has a certain range of manufacturing errors. Furthermore, fixing the chassis to the tooling introduces new positioning and fixing errors. The accumulation of these errors makes it difficult to ensure precise and complete alignment between the press head and the assembly end of the chassis during actual operation.

[0003] To address this alignment challenge, existing technologies in the industry have adopted a solution of designing a floating structure for the pressure head. This design aims to enable the pressure head to automatically adjust its alignment during pressing or disassembly, ensuring its smooth operation of the bushing and thus guaranteeing the normal progress of the operation and the stability of the assembly quality. Relevant prior art, such as Chinese patent application "A Floating Pressure Component", application number: CN202210706260.5, discloses a pressure head base and a pressure head. The pressure head base includes a cylindrical part with an opening facing downward and an installation handle disposed on the upper end face of the cylindrical part. The pressure head includes a disc part and a rod-shaped part. A columnar protrusion is provided in the center of the upper end face of the disc part. The end face of the protrusion is provided with a groove for accommodating a large steel ball. The outer circumferential surface of the disc part is provided with multiple blind holes at intervals, each of which is equipped with a spring. In the cylindrical part of the pressure head base, from top to bottom, a large steel ball pad, a large steel ball, an upper steel ball ring, a pressure head, a lower steel ball ring, a steel ball ring support plate, an O-ring, and an O-ring support plate are installed sequentially. The middle and lower parts of the cylindrical part of the pressure head base are provided with multiple screw holes distributed in a ring. The position of the middle screw hole corresponds to the blind hole on the disc part of the pressure head and a spring limiting screw is installed therein. The position of the lower screw hole corresponds to the O-ring support plate and a locking screw is installed therein.

[0004] However, the existing floating pressure head components have a relatively complex structural design, involving the coordinated operation of multiple components. On the one hand, this increases the difficulty of manufacturing the components, leading to a significant increase in production costs. For large-scale industrial applications, this undoubtedly increases the production input and operating costs for enterprises. On the other hand, the complex structure also makes the components more prone to failure and damage during actual use. Once a key component fails, it will directly affect the efficiency and quality of pressing and disassembly work, and the repair is difficult, requiring a lot of time and manpower for repair, further affecting the continuity of production and the economic benefits of enterprises. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a spherical pressure head floating assembly, which has the advantages of simple structure, low cost and high reliability.

[0006] The technical solution adopted in this application is: a spherical pressure head floating assembly, including a flange seat and a floating pressure member. The flange seat is connected to a power drive component. The floating pressure member includes a pressure head and a connecting member connected vertically. The connecting member has a spherical structure and is installed on the flange seat and movably connected to the flange seat. A limiting ring is provided on the outer sleeve of the floating pressure member. The limiting ring is installed on the flange seat. There is a gap between the inner wall surface of the limiting ring and the floating pressure member. The upper end of the pressure head extends out of the limiting ring.

[0007] Compared with the prior art, the advantages of this application are as follows: First, the structure of this application is relatively simple, mainly consisting of a flange seat, floating pressure components (including pressure head and ball connector) and a limiting ring. The number of components is small. Compared with the complex floating pressure component assemblies in the prior art, the number and types of parts are greatly reduced, the manufacturing complexity is reduced, and thus the production cost is effectively reduced. For large-scale industrial applications, it can significantly reduce the production input and operating costs of enterprises.

[0008] Secondly, due to the simplified structure of this application, the probability of failure during actual use is greatly reduced. Complex component coordination often leads to the failure of the entire assembly due to the failure of a single component. However, the connection and coordination between the components in this solution are simpler and clearer. The movable connection between the spherical connector and the flange seat, as well as the limiting and protective function of the limiting ring, make the assembly more stable and reliable during operation. This reduces the failure points caused by structural complexity, lowers the difficulty and cost of maintenance, helps ensure the continuity and efficiency of pressing and disassembly work, and improves the production efficiency and economic benefits of enterprises.

[0009] Finally, the floating pressure head is movably connected to the flange seat via a spherical connector. This spherical structure allows the pressure head to float freely within a certain range, enabling automatic alignment and effectively compensating for frame manufacturing errors and tooling fixation errors, ensuring the pressure head can smoothly act on the bushing. Simultaneously, the limiting ring reasonably restricts the movement range of the floating pressure head, ensuring sufficient floating space for automatic alignment while preventing problems such as dislodgement or jamming due to excessive movement. This enhances the stability and reliability of the component's operation while maintaining flexibility, contributing to improved assembly quality stability.

[0010] In this application, for ease of description, the figures in the specification are used as reference. Figure 3 The vertical position is distinguished based on the reference point. However, this does not mean that the actual orientation is used in this application.

[0011] In some embodiments of this application, the application further includes a flange cover plate, and an installation groove is provided on the upper end face of the flange seat. The installation groove has a hemispherical structure, and the lower half of the connector is embedded in the installation groove. The flange cover plate is pressed and fixed on the upper half of the connector to restrict the connector within the flange seat.

[0012] By setting flange cover plates and hemispherical mounting grooves, stable support and reliable positioning are provided for the connecting parts, ensuring that they are firmly installed in the flange seat, preventing loosening or displacement during operation, and improving the overall stability and reliability of the components.

[0013] In some embodiments of this application, the flange seat is stepped, and the flange seat includes a base plate and a top plate arranged coaxially, with the top plate located above the base plate, and the diameter of the base plate being larger than the diameter of the top plate.

[0014] The stepped design of the flange seat, with a base diameter larger than the top plate, enhances the overall stability of the flange seat, provides a more stable foundation for the components above, and facilitates connection and matching with tooling or power drive components of different sizes and structures, improving component adaptability.

[0015] In some embodiments of this application, the chassis has a racetrack-shaped structure, the limiting ring is fixed on the chassis, the limiting ring is sleeved on the outside of the top plate, and there is a gap between the inner wall surface of the limiting ring and the outer peripheral surface of the top plate.

[0016] The racetrack-shaped structure of the chassis allows it to better adapt to installation spaces or tooling of specific shapes. The spacing between the limit ring and the top plate restricts excessive movement of the floating pressure component while reserving sufficient space for its movement, ensuring the automatic alignment function.

[0017] In some embodiments of this application, the top plate is a disc-shaped structure, the flange cover is coaxially arranged with the top plate, the outer diameter of the flange cover is equal to the outer diameter of the top plate, the flange cover is disposed on the surface of the top plate, and the flange cover is fixedly connected to the top plate.

[0018] The design of the top plate and the flange cover plate being coaxial and having the same outer diameter ensures their concentricity, allowing the flange cover plate to evenly press against the top plate, enhancing connection stability and reliability, while also facilitating processing and assembly and improving production efficiency.

[0019] In some embodiments of this application, a buffer ring is filled between the pressure head and the inner wall of the limiting ring, and the buffer ring is made of elastic material; a retaining ring is provided in the middle of the inner wall of the limiting ring, and the buffer ring is mounted on the retaining ring.

[0020] The buffer ring mitigates impact and vibration between the pressure head and the limit ring, protecting both from damage and extending their service life. The protruding retaining ring provides stable support and positioning for the buffer ring, ensuring it maintains the correct position during operation and achieves optimal buffering performance.

[0021] In some embodiments of this application, a positioning ring is installed above the limiting ring. The inner diameter of the positioning ring is smaller than the outer diameter of the buffer ring, and the inner diameter of the positioning ring is larger than the outer diameter of the pressure head. The positioning ring is located above the buffer ring.

[0022] The locking ring can effectively limit the upper limit position of the buffer ring, prevent the buffer ring from shifting upward or falling out under impact, ensure that the buffer ring is always in close contact with the pressure head, stably perform the buffering function, and further improve the reliability of this application.

[0023] In some embodiments of this application, the buffer ring is made of polyurethane material. Polyurethane material has high strength, toughness, and wear resistance, and can withstand greater pressure and friction, ensuring that the buffer ring maintains good performance during long-term use, reducing wear and deformation, and extending the component maintenance cycle and service life, making it a preferred solution in this application.

[0024] In some embodiments of this application, the pressure head is generally cylindrical, and a cylindrical recess is formed on the top surface of the pressure head.

[0025] The pressure head structure is compatible with common cylindrical bushings. The recess on the top surface prevents air from entering the bushing core, ensuring that the pressure head can accurately act on the designated position of the bushing, improving assembly accuracy and reliability.

[0026] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[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] Spherical pressure head floating assembly, Example 1 as follows Figure 1 , Figure 2 As shown: It includes a flange seat 1 and a floating pressure member 2. The flange seat 1 is connected to the power drive component. The floating pressure member 2 includes a pressure head 21 connected vertically and a connecting member 22. The connecting member 22 has a spherical structure. The connecting member 22 is installed on the flange seat 1 and is movably connected to the flange seat 1. This spherical structure allows the pressure head 21 to float freely within a certain range, which can automatically adjust the centering and effectively compensate for the frame manufacturing error and the error fixed on the tooling, ensuring that the pressure head 21 can act smoothly on the bushing.

[0033] The floating pressure component 2 is fitted with a limiting ring 5, which is mounted on the flange seat 1. A gap exists between the inner wall of the limiting ring 5 and the floating pressure component 2, and the upper end of the pressure head 21 extends beyond the limiting ring 5. The limiting ring 5 effectively restricts the movement range of the floating pressure component 2, ensuring sufficient floating space for the pressure head 21 to achieve automatic centering while preventing problems such as disengagement or jamming that may result from excessive movement of the floating pressure component 2. This enhances the stability and reliability of the component's operation while maintaining flexibility, contributing to improved assembly quality stability.

[0034] The structure of this application is relatively simple. Compared with the complex floating pressure component 2 assembly in the prior art, it significantly reduces the number and types of parts, lowers the complexity of manufacturing, and thus effectively reduces production costs. The probability of failure during actual use is greatly reduced. This makes the assembly more stable and reliable during operation, reduces failure points caused by structural complexity, lowers maintenance difficulty and costs, helps ensure the continuity and efficiency of pressing and disassembly work, and improves the enterprise's production efficiency and economic benefits.

[0035] In this application, for ease of description, the figures in the specification are used as reference. Figure 3The vertical position is distinguished based on the reference point. However, this does not mean that the actual orientation is used in this application.

[0036] Example 2, as Figures 1 to 4 As shown, this application also includes a flange cover plate 6. A mounting groove 7 is formed on the upper surface of the flange seat 1. The mounting groove 7 has a hemispherical structure. The lower half of the connector 22 is embedded in the mounting groove 7. The flange cover plate 6 is pressed against the upper half of the connector 22, confining the connector 22 within the flange seat 1. By providing the flange cover plate 6 and the hemispherical mounting groove 7, stable support and reliable positioning are provided for the connector 22, ensuring its secure installation within the flange seat 1, preventing loosening or displacement during operation, and improving the overall stability and reliability of the component.

[0037] The flange seat 1 is stepped, and includes a base plate 8 and a top plate 9 coaxially arranged, with the top plate 9 located above the base plate 8. The diameter of the base plate 8 is larger than the diameter of the top plate 9. The stepped design of the flange seat 1, with the base plate 8 having a larger diameter than the top plate 9, enhances the overall stability of the flange seat 1, provides a more stable foundation for the components above, and facilitates connection and matching with tooling or power drive components of different sizes and structures, improving component adaptability.

[0038] The chassis 8 has a racetrack-shaped structure, and the limiting ring 5 is fixed to the chassis 8. The limiting ring 5 is sleeved on the top plate 9, and there is a gap between the inner wall surface of the limiting ring 5 and the outer peripheral surface of the top plate 9. The racetrack-shaped structure of the chassis 8 allows it to better adapt to installation spaces or tooling of specific shapes. The gap between the limiting ring 5 and the top plate 9 limits excessive movement of the floating pressure component 2 while reserving sufficient space for the floating pressure component 2 to ensure the automatic alignment function.

[0039] The top plate 9 has a disc-shaped structure, and the flange cover plate 6 is coaxially arranged with the top plate 9. The outer diameter of the flange cover plate 6 is equal to the outer diameter of the top plate 9. The flange cover plate 6 is disposed on the surface of the top plate 9 and is fixedly connected to the top plate 9. The coaxial design of the top plate 9 and the flange cover plate 6 with equal outer diameters ensures their concentricity, allowing the flange cover plate 6 to evenly press against the top plate 9, enhancing connection stability and reliability. It also facilitates processing and assembly, improving production efficiency.

[0040] A buffer ring 11, made of elastic material, fills the space between the pressure head 21 and the inner wall of the limiting ring 5. A retaining ring 12 protrudes from the center of the inner wall of the limiting ring 5, and the buffer ring 11 rests on the retaining ring 12. The buffer ring 11 can alleviate the impact and vibration between the pressure head 21 and the limiting ring 5, protecting both from damage and extending their service life. The protrusion of the retaining ring 12 provides stable support and positioning for the buffer ring 11, ensuring that the buffer ring 11 maintains the correct position during operation and exerts a good buffering effect.

[0041] A locking ring 13 is installed above the limiting ring 5. The inner diameter of the locking ring 13 is smaller than the outer diameter of the buffer ring 11, while the inner diameter of the locking ring 13 is larger than the outer diameter of the pressure head 21. The locking ring 13 is located above the buffer ring 11. The locking ring 13 can effectively limit the upper limit position of the buffer ring 11, preventing the buffer ring 11 from shifting upward or dislodging under impact, ensuring that the buffer ring 11 is always in close contact with the pressure head 21, stably performing its buffering function, and further improving the reliability of this application.

[0042] The buffer ring 11 is made of polyurethane material. Polyurethane material has high strength, toughness and wear resistance, and can withstand greater pressure and friction, ensuring that the buffer ring 11 maintains good performance during long-term use, reducing wear and deformation, and extending the component maintenance cycle and service life, which is the preferred solution of this application.

[0043] The pressure head 21 has an overall cylindrical structure, and a cylindrical recess 14 is formed on the top surface of the pressure head 21. The structure of the pressure head 21 can be well matched with common cylindrical bushings. The recess 14 on the top surface can prevent air from entering the inner core of the bushing, ensuring that the pressure head 21 can accurately act on the designated position of the bushing, thereby improving assembly accuracy and reliability.
