Description

Technical Field

[0001] The invention relates to the technical field of automobile parts installation, and in particular to an installation device for a rubber bushing of an automobile lower swing arm. Background Art

[0002] The lower arm of a car, also known as a triangular arm, is provided with a mounting sleeve at its end, and the rubber bushing is generally pressed into the mounting sleeve by a bushing transverse push mechanism. However, during the installation process of the rubber bushing, there is overpressure, which causes the end flange on the side adjacent to the rubber bushing and the bushing transverse push mechanism (extending radially outward along the rubber bushing body) to be squeezed into the mounting sleeve. At the same time, there is a one-sided limit between the core shaft of the bushing transverse push mechanism and the rubber bushing, that is, during the transverse push process, the core shaft drives the bushing to move laterally through the step surface that fits the bushing. During the retreat of the bushing transverse push mechanism, the core shaft comes out of the bushing, causing the end flange that is squeezed into the mounting sleeve to be unable to come out, and the bushing needs to be adjusted manually later.

[0003] Therefore, we propose a mounting device for a rubber bushing of a lower swing arm of an automobile. Summary of the invention

[0098] When using this device:

[0099] S1, the automobile lower swing arm is installed on the automobile lower swing arm positioning and pressing mechanism 2, supported by the support plate 211, the support seat 212 and the support column 213, positioned (hole position) by the first positioning pin 221 and the second positioning pin 222, and fixed by the pressing chuck 231 and the pressing cylinder 232;

[0100] S2, the rubber bushing P is mounted on the core shaft 33 and fits with the end surface of the thick rod section 332;

[0101] S3, the bushing flange limiting mechanism 5 is driven to move upward by the vertical driving unit 41 of the bushing synchronous retreat mechanism 4. During the upward movement, refer to the attached Figure 5-8 , especially with reference to Figure 6-8 First, the pressure strip mounting seat 52 is limited by the limiting plate 57 and the limiting seat 58, and the pressure strip 51 is at the same height as the mounting sleeve. Then, the driving rod 54 continues to move upward. After the driving rod 54 contacts the slide bar 53, the two cooperate through the inclined surface to push the slide bar 53 in. The (upper opening) ring formed by the combination of a pair of pressure strips 51 is concentric and fits with the mounting sleeve. During this period, the push plate 44 keeps moving upward synchronously, but it will be lower than the core shaft 33 and will not interfere with the lateral movement of the core shaft 33.

[0102] S4, the horizontal driving unit 31 of the bushing horizontal pushing mechanism 3 drives the core shaft 33 and the bushing to move forward synchronously, and inserts the rubber bushing P into the installation sleeve. The front end flange of the rubber bushing P will pass through between the pair of pressure strips 51, and the rear end flange of the rubber bushing P is usually squeezed into the installation sleeve;

[0103] S5, the vertical driving unit 41 of the bushing synchronous retraction mechanism 4 continues to drive the push plate 44 to move upward, so that the push plate 44 is engaged with the groove 3311 of the core shaft 33;

[0104] S6, the horizontal driving unit 31 of the bushing horizontal pushing mechanism 3 drives the core shaft 33 to retreat, and drives the rubber bushing P to retreat through the push plate 44 until its exposed front end flange is embedded between a pair of pressure strips 51, and is restricted in advance by the inclined arc surface 5111 on the inner side of the pressure strip, so that it is squeezed, pulled, and deformed, and the front end flange is prevented from falling into the installation sleeve, while the rear end flange of the rubber bushing P can continue to retreat and be smoothly removed;

[0105] S7, the vertical driving unit 41 of the bushing synchronous retraction mechanism 4 drives the push plate 44 to move downward, so that the push plate 44 disengages from the core shaft 33, and the disengaged push plate 44 can be reset along the elastic sliding seat 42 under the action of the reset member and the sliding block 43; during this period, the pressure strip mounting seat 52 first maintains contact with the limit plate 57 under the action of the vertical spring 56, until the driving rod 54 is out of contact with the sliding rod 53, and the sliding rod 53 extends outward again, driving the pressure strip 51 to withdraw (after the pressure strip 51 withdraws, the front end flange deformation of the rubber bushing P is restored), and the pressure strip mounting seat 52 and the pressure strip 51 move downward synchronously with the push plate 44 and the driving rod 54.

[0106] In this embodiment, the limiting structure includes limiting bolts 45, and a pair of limiting bolts 45 are respectively installed on the two side walls of the elastic sliding seat 42. The first reset member is a horizontal spring 46, and the horizontal spring 46 is sleeved on one of the limiting bolts 45 and its two ends are respectively against the elastic sliding seat 42 and the side wall of the elastic sliding seat 42. The limiting structure is simple and reliable. On the one hand, the terminal position of the sliding direction of the elastic sliding seat 42 can be conveniently adjusted by the limiting bolts 45. On the other hand, a nut can be added to the limiting bolts 45 to adjust the elastic force of the horizontal spring 46.

[0107] In this embodiment, a notch is formed at the upper end of the pair of pressure strips 51 after being assembled, that is, the arc surfaces 5111 of the two cannot be assembled to form a closed circle, which can reduce the distance that the pressure strip moves laterally from the exposed end flange of the rubber bushing P and the installation sleeve.

[0108] In this embodiment, the guide member is a guide column 55, and the second elastic member is a vertical spring 56. The vertical spring 56 is sleeved on the guide column 55 and its two ends respectively abut against the pressure strip mounting seat 52 and the panel of the vertical driving bracket.

[0109] In this embodiment, a downwardly extending mounting portion 512 is formed at the lower end of the strip-shaped main body 511 of the pressure strip, and the mounting portion 512 is embedded in the slide rod 53 and fixedly connected to the slide rod 53, and the slide rod 53 is slidably mounted on the pressure strip mounting seat 52. Specifically, the pressure strip mounting seat 52 is provided with a slide groove extending along the length direction, and the upper end of the slide groove is open, and pressure plates 59 are respectively installed at both ends of the slide groove opening, and the side wall 521 of the slide groove is formed with a convex guide portion 531 along the outside thereof, and the two side walls of the slide rod 53 are formed with a concave guide groove 5211, and the guide portion 531 extends into the guide groove 5211 and slides and guides with the guide groove 5211. The guide portion 531 and the guide groove 5211 are preferably a two-section structure, i.e., one section is narrower and the other section is wider, and a step surface is formed at the junction of the two sections, which facilitates limiting the lateral movement of the slide rod 53 through the step surface, so that only the end of the slide rod 53 that cooperates with the drive rod 54 (i.e., the part with the inclined surface) is exposed.
