Description

Technical Field

[0001] This utility model relates to the field of bushing pressing equipment, specifically to a torsion beam shock-absorbing bushing floating pressing device. Background Technology

[0002] The torsion beam rear axle is a common type of automotive rear suspension frame and is an important component for maintaining vehicle stability and comfort. The automotive rear axle torsion beam assembly consists of a rear torsion beam bushing, torsion beam crossbeam, torsion beam longitudinal arm, and sleeve, among other components.

[0003] During the assembly process, because the rear torsion beam bushing is a rubber part, the clamping force is large. During the pressing of the rear torsion beam bushing into the sleeve, the parts are often deformed, scratched, and the pressing force is too large, which seriously affects the pressing qualification rate.

[0004] Because the bushing is a rubber component, the pressure during press-fitting is uneven and the clamping force is large, resulting in a high failure rate. To improve the pass rate, reduce production costs, and increase production efficiency, it is necessary to replace and optimize press-fitting devices with purely rigid connections. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this utility model provides a floating press-fitting device for torsion beam damping bushings. It has a simple structure, is easy to clamp, and adopts floating press-fitting, resulting in high press-fitting efficiency and high product qualification rate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0017] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] One such Figure 1-3The torsion beam damping bushing floating press-fitting device shown includes a base 1, on which two sets of support seats 2 are symmetrically arranged. Each set of support seats 2 has a connecting plate support nail 4, a spring disc support positioning block 5, and a longitudinal arm positioning nail 6 on its top surface. The connecting plate support nail 4 supports the torsion beam below the hub connecting plate. The spring disc support positioning block 5 supports the spring disc on the torsion beam and corresponds to the central protrusion of the spring disc. The longitudinal arm positioning nail 6 is a conical positioning nail used to support and position the longitudinal arm of the torsion beam at the bottom near the bushing tube. To facilitate rapid installation of the torsion beam, a pre-positioning block 14 is provided on the support seat 2 in this embodiment. A lever clamping cylinder 7 is provided on the side of the support seat 2 to press the top surface of the longitudinal arm of the torsion beam. A pressure block is connected to the pressure arm of the lever clamping cylinder 7, and the pressure block has two pressing parts. This allows the torsion beam to be completely positioned and clamped.

[0019] A floating pressing mechanism is provided on one side of the support base 2. The floating pressing mechanism includes a base plate 8, a sliding plate 9 slidably mounted on the base plate 8, and a pressing seat 10 floatingly mounted on the sliding plate 9. One end of the pressing seat 10 has a bushing positioning seat 11, and a pressing head 12 slidably mounted on the pressing seat 10, directly opposite the bushing positioning seat 11. The other end of the pressing seat 10 is provided with an electric push rod 13 that drives the pressing head 12. The working process is as follows: first, the shock-absorbing bushing is manually positioned onto the bushing positioning seat 11; then, the sliding plate 9 moves so that the bushing on the bushing positioning seat 11 is close to the bushing tube on the torsion beam; then, the electric push rod 13 presses against the other end of the bushing tube. At the same time, the floating pressing seat 10 remains floating during the pressing process, so that the bushing is subjected to force from multiple angles, thereby ensuring smooth pressing.

[0020] A slider 15 is fixedly installed on the base plate 8. A linear guide rail 16 that cooperates with the slider 15 is installed at the bottom of the slide plate 9. A blocking block 17 is installed on the base plate 8. A drive cylinder 18 is installed at one end of the slide plate 9. The front end of the piston rod of the drive cylinder 18 is connected to the blocking block 17. The drive cylinder is located on one side of the electric push rod 13. During pressing, the drive cylinder 18 maintains the pressing state, so that the bushing can always fit tightly against the bushing tube.

[0021] like Figure 3As shown, the top surface of the slide plate 9 has a vertically arranged positioning shaft 19 in the center, and the bottom surface of the pressing seat 10 has a bushing 20 that slides with the positioning shaft 19 in the center. This structure allows the pressing seat 10 to move vertically. The four bottom corners of the pressing seat 10 have protruding floating support plates 21 for maintaining the pressing seat 10 in a floating support state. The slide plate 9 has a floating support rod assembly 22 that abuts against the bottom surface of the floating support plate 21, and a floating pressure rod assembly 23 that abuts against the top surface of the floating support plate 21. Furthermore, the pressing seat 10 has floating pressure cylinders 24 at both ends. The lower end of the piston rod of the floating pressure cylinder 24 abuts against the top surface of the slide plate 9. The angle of the pressing seat 10 can be adjusted by the extension and retraction of the pressure cylinder 24, thus placing the pressing seat 10 in a floating or rocking state, resulting in different force directions during bushing pressing.

[0022] like Figure 3 As shown, the floating support rod assembly 22 includes a suspension rod 211 disposed on the bottom surface of the slide plate 9. The lower end of the suspension rod 211 is connected to a suspension support plate 213. Spring support sleeves 214 are disposed at both ends of the top surface of the suspension support plate 213. A vertically movable support rod 215 is disposed on the spring support sleeve 214. A first spring 216 is sleeved on the support rod 215. The lower end of the first spring 216 is limited to the spring support sleeve 214, and the upper end of the first spring 216 is limited to the shoulder of the support rod 215. The upper end of the support rod 215 contacts the floating support plate 21 through a first steel ball 217. The floating support plate 21 has an arc-shaped groove corresponding to the first steel ball 217.

[0023] like Figure 3 As shown, the floating pressure rod assembly 23 includes a mounting base 231 on the top surface of the slide plate 9. A spring pressing screw sleeve 232 is provided on the upper part of the mounting base 231. A vertically movable pressure rod 233 is provided on the spring pressing screw sleeve 232. A second spring 234 is sleeved on the pressure rod 233. The upper end of the second spring 234 is limited on the spring pressing screw sleeve 232, and the lower end of the second spring 234 is limited on the lower shoulder of the pressure rod 233. The lower end of the pressure rod 233 contacts the floating support plate 21 through the second steel ball 235.
