Description

Technical Field

[0001] This utility model relates to the field of rubber flange bushing press-fitting, specifically to a rubber flange bushing press-fitting device. Background Technology

[0002] The suspension system serves as a connection between the powertrain and the vehicle body. Its main function is to support the powertrain and reduce the impact of powertrain vibrations on the overall vehicle performance, playing a significant role in the overall vehicle's performance. Axle mount structures, such as... Figure 1 It consists of an aluminum alloy body and multiple bushings. How to press-fit multiple rubber flange bushings onto the suspension body is a common problem in production. The common method is to press-fit the bushings in different spatial positions separately; however, this installation process is cumbersome, involves many steps, requires a large equipment footprint, and because the positions of different flange bushings are different, step-by-step pressing can easily lead to accuracy deviations and insufficient product quality consistency.

[0003] A search revealed CN201420138023.4, which discloses a suspension assembly fixture. This fixture improves upon existing fixtures by adding a groove to the upper module and lower template for limiting and pressing; and adds a sliding positioning device to the lower template. Products assembled using the improved fixture, compared to those assembled using the original fixture, no longer experience eccentricity due to excessive pressing stroke required for simultaneously pressing bushings and support arms. The improved pressing fixture shortens the pressing stroke, thus preventing issues such as angle deviations between the support arms and brackets after installation due to excessive pressing stroke, failure to pass inspection, and bushing misalignment leading to damage.

[0004] However, the above-mentioned fixture only presses on a single bushing, and the upper pressure head is a rigid structure. Its purpose is to quickly and accurately position the bushing support arm, but it cannot solve the problem that different flange bushings have different positions, and step-by-step pressing can easily cause accuracy deviations and insufficient product quality consistency.

[0005] Therefore, it is essential to invent a rubber flange bushing pressing device that allows for simultaneous pressing by multiple pressure heads. Utility Model Content

[0006] To address the shortcomings of the existing technology, this utility model discloses a rubber flange bushing pressing device, which integrates a multi-station pressing line into a single tooling by pressing bushings at different spatial positions on the same assembly body into the body at one time; effectively reducing investment and improving efficiency.

[0007] This utility model's rubber flange bushing pressing device enables the pressing of multiple flange bushings at the same station in one operation; it is highly efficient and produces high-precision products.

[0008] The technical means adopted by this utility model to solve the above problems are as follows:

[0009] A rubber flange bushing press-fitting device is disclosed, comprising an upper press head module and a lower support module that cooperates with the upper press head module. The upper press head module includes an upper pressure plate, and a first limiting structure, a press head assembly, and a guide post structure are provided on one side of the upper pressure plate. The press head assembly consists of multiple press heads arranged at different heights, including a reference press head and multiple elastic press heads. The lower support module includes a support seat mounted on a lower mounting plate. The support seat cooperates with the press head assembly to press the rubber flange bushing. A guide sleeve structure is provided on the outer periphery of the support seat, and the guide sleeve structure is sleeved with the guide post structure. A second limiting structure is provided on one side of the support seat, which abuts against the first limiting structure. An adjustment structure is provided between the elastic press head and the upper pressure plate to adjust the height of the rubber flange bushing at different positions during press-fitting.

[0010] The challenge in press-fitting multiple bushings at different spatial locations on the same substrate lies in the inconsistency in height at these locations. Without machining, these height differences fluctuate within their respective tolerances during mass production. Using conventional rigid press heads would result in bushings at certain locations not being properly press-fitted. The innovation of this rubber flange bushing press-fitting device lies in its design of a reference press head and multiple flexible press heads that work together. The flexible press heads are designed with a fine-tuning structure to overcome the aforementioned problems.

[0011] Furthermore, the support base and the pressure head assembly are coaxially and correspondingly arranged vertically, and the position of the support base is set to be the same as the installation position of the rubber flange bushing of the shaft suspension; the reference pressure head is set on one side of the multiple elastic pressure heads as a reference.

[0012] Furthermore, the reference pressure head includes a pressure head outer sleeve and a pressure block disposed on the inner wall of the pressure head outer sleeve, wherein the pressure block has a pressing portion at its center.

[0013] Furthermore, the support base includes a support jacket and a protrusion disposed within the support jacket, the bottom of the protrusion abutting against the support jacket via an adjustment portion.

[0014] Furthermore, the first limiting structure and the second limiting structure are rod-shaped bodies with the same diameter and arranged coaxially.

[0015] Furthermore, the guide sleeve structure is disposed outside the rubber flange bushing of the shaft suspension and is arranged laterally without contact with the shaft suspension; the guide sleeve structure is a hollow sleeve body, and the guide post structure is a columnar body with a length shorter than the guide post structure.

[0016] Furthermore, the adjustment structure is a leaf spring.

[0017] Furthermore, the elastic pressure head includes a contact pressure head with a cavity inner wall, the bottom opening of the contact pressure head is set with a stepped variable diameter, and a limiting guide rod is provided inside the contact pressure head, the limiting guide rod having an inverted T-shaped rod structure in cross-section.

[0018] Furthermore, the limiting guide rod is fixedly connected to the upper pressure plate, and the top of the contact pressure head is provided with a connecting part, and the contact pressure head and the connecting part abut against each other by a leaf spring.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

The rubber flange bushing pressing device of this utility model sets up multiple pressing stations between the upper and lower plates at the same time, realizing the rapid and accurate positioning of the bushing and the pressing body, and greatly improving the working efficiency of pressing multiple bushings at one time.

[0021] 2. The rubber flange bushing press-fitting device of this utility model has a compact structural design. The compact design not only facilitates installation, but also simplifies daily maintenance and repair work, and reduces operating costs.

[0022] 3. The rubber flange bushing press-fitting device of this utility model can be quickly adjusted and customized according to different shaft suspension products and performance requirements, which greatly shortens the product development cycle. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only, representing schematic diagrams only, not actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Example 1

[0031] like Figures 1-5 As shown, the rubber flange bushing pressing device of this embodiment includes an upper pressing head module A and a lower support module B that cooperates with the upper pressing head module A. The upper pressing head module A includes an upper pressing plate 1. A first limiting structure 2, a pressing head assembly 3, and a guide post structure 4 are provided on one side of the upper pressing plate 1. The pressing head assembly 3 consists of multiple pressing heads arranged at different heights, including a reference pressing head 31 and multiple elastic pressing heads 32. The lower support module B includes a support seat 6 mounted on a lower mounting plate 5. The support seat 6 cooperates with the pressing head assembly 3 to press the rubber flange bushing. A guide sleeve structure 7 is provided on the outer periphery of the support seat 6. The guide sleeve structure 7 is sleeved with the guide post structure 4. A second limiting structure 8 is provided on one side of the support seat 6, which abuts against the first limiting structure 2. An adjustment structure is provided between the elastic pressing heads 32 and the upper pressing plate 1 to adjust the height of the rubber flange bushing at different positions during pressing. The first limiting structure 2 and the second limiting structure 8 are rod-shaped bodies with the same diameter arranged coaxially.

[0032] In this embodiment, the support base 6 and the pressure head assembly 3 are coaxially and correspondingly arranged. The position of the support base 6 is set to be the same as the installation position of the rubber flange bushing of the shaft suspension. In this embodiment, it consists of one main rubber flange bushing and three auxiliary rubber flange bushings. The diameter of the main rubber flange bushing is larger than the diameter of any of the auxiliary rubber flange bushings, and its mounting surface is higher than the mounting surface of the other auxiliary rubber flange bushings.

[0033] Therefore, this device is equipped with a reference pressure head 31, which is positioned on one side of the three elastic pressure heads 32 as a reference. The reference pressure head 31 includes a pressure head outer sleeve 311 and a pressure block 312 disposed on the inner wall of the pressure head outer sleeve 311, with a crimping portion 313 at the center of the pressure block 312. In this embodiment, the pressure head outer sleeve 311 is a hollow cylindrical shape, and the crimping portion 313 is designed to match the shape of the crimping end face of the flange bushing. In this embodiment, the center is a through hole, and the two sides are prismatic crimping strips. The pressure block 312 is used to fix the crimping portion 313 and the pressure head outer sleeve 311.

[0034] The first limiting structure 2 and the second limiting structure 8 are connected to jointly limit the vertical pressing of the reference rubber flange bushing A1. Generally, the vertical height of the first limiting structure 2 and the second limiting structure 8 is slightly greater than the sum of the vertical heights of the support base 6, the reference rubber flange bushing A1, and the reference pressure head 31. During pressing, the upper pressure plate 1 and the lower mounting plate 5 are set in parallel. The reference rubber flange bushing A1 is pressed first, and then the other flange bushings around it are positioned and pressed.

[0035] The support base 6 in this embodiment includes a support jacket 61 and a protrusion 62 disposed within the support jacket 61. The support jacket 61 is a hollow cylindrical body with a through hole 611 at the center of its upper surface. The bottom of the protrusion 62 abuts against the support jacket 61 through an adjustment part 63 and extends out of the upper surface of the support jacket 61 through the through hole 611. That is, the entire support base 6 is capable of longitudinal elastic deformation. Specifically, the protrusion 62 is a cylindrical cavity 621 with a spring installed inside. Its top 622 is connected to a conical structure. The bottom of the cylindrical cavity 621 is disposed inside the support jacket 61. A circumferential limiting strip 623 is provided at the bottom of the cylindrical cavity 621. The outer diameter of the circumferential limiting strip 623 is larger than the through hole 611 of the support jacket 61.

[0036] Specifically, the guide sleeve structure 7 is located outside the rubber flange bushing of the shaft suspension, and is arranged laterally without contact with the shaft suspension; the guide sleeve structure 7 is a hollow sleeve, and the guide post structure 4 is a columnar body with a length shorter than the guide post structure 4. The length of the guide post structure 4 is equal to the sum of the vertical heights of the first limiting structure 2 and the second limiting structure 8. This ensures that the entire upper pressure plate 1 and the lower mounting plate 5 are arranged in parallel, resulting in high pressing accuracy.

[0037] The elastic pressure head 32 includes a contact pressure head 321 with a cavity inner wall. The bottom opening of the contact pressure head 321 is set with a stepped diameter change. A limit guide rod 322 is provided inside the contact pressure head 321. The limit guide rod 322 has an inverted T-shaped rod structure in cross-section.

[0038] The limiting guide rod 322 is fixedly connected to the upper pressure plate 1, and the top of the contact pressure head 321 is provided with a connecting part 9. The contact pressure head 321 and the connecting part 9 are abutted by a leaf spring 323.

[0039] like Figure 6As shown, in this embodiment, the step difference between the elastic pressure head and the reference pressure head in its natural state should be at the maximum value of the product step difference, and the preload of the spring should be greater than the maximum pressing force of the bushing. Taking the pressure head at position A1 of the reference rubber flange bushing as the reference pressure head 31, and taking position D1 as an example, the step difference between the pressure head at position D1 and the pressure head at position A1 of the reference rubber flange bushing should be greater than the maximum value of the step difference between main body A1 and D1. During pressing, the pressure head at position D1 first presses the bushing into place, but at this time the pressure head of the reference rubber flange bushing A1 has not yet reached the required position. The press continues to descend until the reference rubber flange bushing A1 is pressed into place. During this process, because the pressure head at position D1 has a certain elasticity, when the machine continues to press down, the leaf spring 323 of the pressure head is compressed and deformed by the pressure, but the bushing will not be damaged due to excessive pressing.

[0040] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the protection scope of the present invention, which should be defined by the claims.
