Description

Technical Field

[0001] The present invention relates to the technical field of automotive component installation, and particularly relates to an installation device for a rubber bushing of an automotive lower control arm. Background Art

[0002] The automotive lower control arm, also known as the triangular arm, is provided with an installation sleeve at its end. The rubber bushing is generally pressed into the installation sleeve through a bushing transverse pushing mechanism. However, during the installation process of the rubber bushing, there is an overpressure situation, which causes the end flange (extending radially outward along the rubber bushing body) on the side adjacent to the bushing transverse pushing mechanism to be squeezed into the installation sleeve. At the same time, there is a unilateral limit between the mandrel of the bushing transverse pushing mechanism and the rubber bushing, that is, during the transverse pushing process, the mandrel drives the bushing to move horizontally through the stepped surface in contact with the bushing. During the retraction process of the bushing transverse pushing mechanism, the mandrel disengages from the bushing, resulting in the end flange squeezed into the installation sleeve unable to disengage. Subsequently, manual adjustment of the bushing is required.

[0003] Therefore, we propose an installation device for a rubber bushing of an automotive lower control arm. Summary of the Invention

The elastic sliding seat is provided with a limiting structure for limiting the sliding of the sliding block and a first reset member for driving the sliding block to move horizontally and reset. The elastic sliding seat is mounted on the output end of the vertical driving unit;

[0011] A groove is provided on the front rod body of the mandrel passing through the rubber bushing to be installed. The push plate moves upward under the action of the vertical driving unit. The U-shaped groove of the push plate engages with the groove of the mandrel. During the retraction of the mandrel, the mandrel drives the bushing to retract until it abuts against the installation sleeve through the push plate.

[0012] Further, the limiting structure includes limiting bolts, and a pair of limiting bolts are respectively installed on the two side walls of the elastic sliding seat.

[0013] Further, the first reset member is a horizontal spring. The horizontal spring is sleeved on one of the limiting bolts and its two ends respectively abut against the elastic sliding seat and the side wall of the elastic sliding seat.

[0014] Further, the installation device includes a bushing flange limiting mechanism. The bushing flange limiting mechanism includes a pressing strip, a pressing strip mounting seat, a sliding rod, a first elastic member, a driving rod, a guiding member, a second elastic member, a limiting plate and a limiting seat. An inclined arc surface is formed on the inner side of the pressing strip. A pair of pressing strips are provided and are respectively slidably installed on the pressing strip mounting seat through independent sliding rods. A pair of first elastic members are built in the pressing strip mounting seat. The end of the sliding rod is exposed outside the pressing strip mounting seat under the action of the first elastic member. The driving rod is vertically installed on the panel of the vertical driving bracket. The pressing strip mounting seat is vertically slidably and guidingly installed on the panel of the vertical driving bracket through a pair of guiding members and is jacked upward under the action of the second elastic member. The driving rod and the sliding rod are in inclined surface cooperation. The sliding rod retracts into the pressing strip mounting seat against the action of the first elastic member, and the pair of pressing strips are joined together.

[0015] Further, a notch is formed at the upper end after the pair of pressing strips are joined together.

[0016] Further, the first elastic member is a nitrogen spring.

[0017] Further, the guiding member is a guide post, the second elastic member is a vertical spring, and the vertical spring is sleeved on the guide post and its two ends respectively abut against the pressing strip mounting seat and the panel of the vertical driving bracket.

[0018] Further, an installation portion extending downward is formed at the lower end of the pressing strip. The installation portion is embedded in the sliding rod and fixedly connected to the sliding rod. The sliding rod is slidably installed in the pressing strip mounting seat.

[0019] Further, the pressing strip mounting seat is provided with a chute extending along the length direction. The upper end of the chute is open. Pressing plates are respectively installed at both ends of the opening of the chute. Guide portions protruding outward are formed on both side walls of the chute. Guide grooves recessed inward are formed on both side walls of the sliding rod. The guide portions extend into the guide grooves and are in sliding and guiding cooperation with the guide grooves.

[0020] Furthermore, the positioning and pressing mechanism for the automotive lower control arm includes a support structure for carrying the automotive lower control arm, a positioning structure for positioning the automotive lower control arm, and a pressing structure for pressing and fixing the automotive lower control arm;

[0022] The positioning structure includes a first positioning pin mounted on the support plate and used for positioning the hole position of the main body of the automotive lower control arm, and a second positioning pin mounted on the support column and used for positioning the end of the automotive lower control arm;

[0023] The pressing structure includes a pressing cylinder, a pressing chuck, and a pressing mounting seat. The pressing cylinder is mounted on the pressing mounting seat and its output end is connected with the pressing chuck. The pressing cylinder presses and fixes the automotive lower control arm on the support plate and the support column by driving the pressing chuck.

[0024] The bushing horizontal pushing mechanism includes a horizontal driving unit, a horizontal push rod bracket, and a mandrel. The horizontal driving unit is mounted on the horizontal push rod bracket and its output end is mounted with the mandrel. The mandrel is in a stepped shape. The thin rod section of the mandrel penetrates through the central perforation of the rubber bushing to be installed and a groove is provided at its front end. The end face of the thick rod section of the mandrel is attached to the end face of the rubber bushing.

[0025] (III) Beneficial effects

[0026] The present invention provides an installation device for a rubber bushing of an automotive lower control arm, having the following beneficial effects:

[0027] (1) On the basis of the bushing horizontal pushing mechanism, the installation device is additionally provided with a bushing synchronous retracting mechanism. During use, first drive the push plate to move upward to realize the engagement between the push plate and the mandrel. During the retraction process of the mandrel, drive the bushing to retract until the exposed end flange thereof abuts against the installation sleeve through the push plate, so that the end flange of the rubber bushing extruded into the installation sleeve can be smoothly disengaged. Then drive the push plate to move downward to disengage the push plate from the mandrel. The disengaged push plate can be reset along the elastic sliding seat under the action of the reset member and the sliding block; the overall structure is simple and compact, and the use effect is good.

[0028] (2) On the basis of the bushing synchronous retracting mechanism, the installation device is additionally provided with a flange limiting mechanism. The exposed end flange is restricted by a pair of pressure strips with inclined arc surfaces on the inner side, so as to avoid the situation that the exposed end flange part or even the whole of the rubber bushing is embedded in the installation sleeve during the process of the push plate driving the rubber bushing to retract.

[0029] (3) The upward movement, splicing, and separation of a pair of pressing strips occur synchronously during the vertical movement of the push plate, that is, they use the same vertical driving unit as the push plate, which can effectively reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

A pair of pressing strips 51 are provided and are respectively slidably mounted on the pressing strip mounting seat 52 through independent sliding rods 53. A pair of first elastic members (preferably nitrogen springs) are built in the pressing strip mounting seat 52. The end of the sliding rod 53 is exposed outside the pressing strip mounting seat 52 under the action of the first elastic member. The driving rod 54 is vertically mounted on the panel of the vertical driving bracket. The pressing strip mounting seat 52 is vertically slidably guided and mounted on the panel of the vertical driving bracket through a pair of guiding members and is jacked up under the action of the second elastic member. The driving rod 54 and the sliding rod 53 are in inclined surface cooperation. The sliding rod overcomes the action of the first elastic member and retracts into the pressing strip mounting seat 52, and the pair of pressing strips 51 are joined together.

[0098] When the device is in use:

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

[0100] S2, the rubber bushing P is sleeved on the mandrel 33 and abuts against the end face 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 retraction mechanism 4. During the upward movement, referring to the appendix Figures 5-8 and especially referring to the appendix Figures 6-8 , first, the pressing strip mounting seat 52 is first limited by the cooperation of the limiting plate 57 and the limiting seat 58, and the pressing strip 51 is at the same height as the mounting sleeve. Then, when the driving rod 54 continues to move upward and contacts the sliding rod 53, the two are in inclined surface cooperation, pushing the sliding rod 53 in. The (upper-opening) ring formed by the joining of the pair of pressing strips 51 is concentric with and abuts against the mounting sleeve. During this period, the push plate 44 moves upward synchronously but will be lower than the mandrel 33 and will not interfere with the lateral movement of the mandrel 33;

[0102] S4, the horizontal driving unit 31 of the bushing transverse pushing mechanism 3 drives the mandrel 33 and the bushing to move forward synchronously, and inserts the rubber bushing P into the mounting sleeve. The front flange of the rubber bushing P will pass through between the pair of pressing strips 51, and the rear flange of the rubber bushing P will more often be squeezed into the mounting 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 to achieve the engagement of the push plate 44 with the groove 3311 of the mandrel 33;

[0104] In S6, the horizontal drive unit 31 of the bushing horizontal pushing mechanism 3 drives the mandrel 33 to retract. The rubber bushing P is driven by the push plate 44 to retract until the exposed front flange thereof is embedded between a pair of pressure strips 51, and is limited in advance by the inclined arc surface 5111 on the inner side of the pressure strip, resulting in extrusion, pulling, and deformation, preventing the front flange from falling into the installation sleeve, while the rear flange of the rubber bushing P can continue to retract and smoothly disengage.

[0105] In S7, the vertical drive 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 mandrel 33. 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 remains in contact with the limiting plate 57 under the action of the vertical spring 56 until the driving rod 54 disengages from the sliding rod 53, and then the sliding rod 53 extends outward, driving the pressure strip 51 to withdraw (after the pressure strip 51 withdraws, the deformation of the front flange of the rubber bushing P is restored), and the pressure strip mounting seat 52 and the pressure strip 51 then 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 respectively abut against the elastic sliding seat 42 and the side wall of the elastic sliding seat 42. This 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 through the limiting bolts 45. On the other hand, nuts can be installed on 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 after a pair of the pressure strips 51 are joined together, that is, the arc surfaces 5111 of the two cannot be joined to form a closed circle, which can reduce the distance for the pressure strip to horizontally move out from between the exposed end flange of the rubber bushing P and the installation sleeve.

[0108] In this embodiment, the guiding member is a guide post 55, the second elastic member is a vertical spring 56, and the vertical spring 56 is sleeved on the guide post 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 downward-extending mounting portion 512 is formed at the lower end of the strip-shaped main body 511 of the pressure strip. The mounting portion 512 is embedded in the sliding rod 53 and fixedly connected to the sliding rod 53. The sliding rod 53 is slidably mounted on the pressure strip mounting seat 52. Specifically, the pressure strip mounting seat 52 is provided with a chute extending along the length direction. The upper end of the chute is open. Pressure plates 59 are respectively mounted at both ends of the opening of the chute. A guiding portion 531 protruding outward along the side wall 521 of the chute is formed. Concave guiding grooves 5211 are formed on both side walls of the sliding rod 53. The guiding portion 531 extends into the guiding grooves 5211 and is in sliding and guiding cooperation with the guiding grooves 5211. The guiding portion 531 and the guiding grooves 5211 are preferably of a two-piece structure, that is, one section has a narrower width and the other section has a wider width, and a step surface is formed at the junction of the two sections, which is convenient for restricting the lateral movement of the sliding rod 53 through the step surface, so that only the end portion of the sliding rod 53 that cooperates with the driving rod 54 (that is, the portion with an inclined surface) is exposed.
