[0002] Currently, during the assembly process of the shock absorber strut and the vehicle body, the upper fixing point of the shock absorber strut is very accurately positioned with the body shock tower. However, when the shock absorber strut spring is pressed, due to the relative sliding between the top cover of the shock absorber strut and the compression spring, it is impossible to ensure the accurate position of the positioning point on the top cover of the shock absorber strut, causing great difficulties in the subsequent positioning and fixing of the shock absorber strut during the suspension and vehicle body assembly. Content of the Utility Model

[0003] The purpose of the utility model is to provide a shock absorber strut pressing tooling, which adjusts the clamping component to clamp and adjust the fixing bolt of the shock absorber strut by using external power, and accurately positions through the horizontal detection and positioning component, ensuring the relative position between the top cover of the shock absorber strut and the compression spring, realizing the accurate positioning of the fixing stud on the top cover of the shock absorber strut, facilitating the assembly of the suspension shock absorber strut; it has a simple structure, is adjustable, is applicable to various shock absorber strut sub-assembly stations, improves the assembly efficiency, and saves costs.

[0004] The specific solution is as follows:

[0005] A shock absorber strut pressing tooling includes a fixture component and a horizontal detection and positioning component, and the horizontal detection and positioning component is fixedly connected to the fixture component.

[0006] This tooling is one of the shock absorber strut pressing toolings, including a fixture component and a horizontal detection and positioning component, and the horizontal detection and positioning component is fixedly connected to the fixture component. This tooling is used in cooperation with other toolings to accurately monitor the relative position between the top cover of the shock absorber strut and the compression spring, and solve the problem of difficult leveling and positioning between the top cover of the shock absorber strut and the compression spring. The horizontal detection and positioning component of the utility model is installed on the fixture component. During the pressing of the shock absorber strut, by adjusting the position of the fixture component to make the horizontal detection and positioning component horizontal, the relative position between the top cover of the shock absorber strut and the compression spring is ensured, avoiding the difficulty of adjusting assembly deviation, reducing the manufacturing cost, and improving the assembly efficiency.

[0007] Furthermore, the fixture component includes a fixed frame, a clamping block component, and a telescopic component. The upper end of the telescopic component is telescopically connected to the lower end of the clamping block component. The clamping block component is limited to move and sleeved within the fixed frame, and the upper end of the clamping block component is exposed outside the upper end of the fixed frame.

[0008] The clamping block component of the fixture component of the utility model is telescopically connected to the upper end of the telescopic component, the clamping block component is limited and sleeved within the fixed frame, and the upper end of the clamping block component extends outside the upper opening of the fixed frame. The telescopic component drives the clamping block component to move accordingly by telescopic movement up or down, and can realize the function of clamping or loosening the fixing bolt of the shock absorber strut.

[0009] Furthermore, the fixing bracket includes a bottom plate, two rectangular frames, two limiting plates and two return springs. The bottom plate is of a rectangular structure. The two rectangular frames are matched and vertically arranged at the edges of the two long sides on the upper end surface of the bottom plate respectively to form a U-shaped frame structure. Horizontal through grooves are provided on the end faces of the upper cross sides of the two rectangular frames that face each other. Each limiting plate is fixedly connected to the corresponding end of the upper cross side of the two rectangular frames. One end of each return spring is fixedly connected to the inner side wall of the corresponding limiting plate, and the other end elastically contacts the corresponding outer side wall of the upper part of the clamping block assembly. A through mounting hole is provided at the center of the bottom plate, and the telescopic assembly is inserted into the mounting hole, and its upper and lower ends are respectively exposed outside the upper and lower ends of the mounting hole.

[0010] The floor of the fixing bracket of the present utility model and the two rectangular frames together form a U-shaped frame structure. Horizontal through grooves are provided on the inner end faces of the upper cross sides of the two rectangular frames that are arranged opposite to each other. The two limiting plates are respectively fixedly connected to the ends of the upper cross sides of the two rectangular frames on the same side. A return spring is fixedly connected to the inner side wall of each limiting plate, and the return spring elastically contacts the corresponding outer side wall of the driven slider. The purpose of installing the limiting plate is to limit the sliding of the two driven sliders in the horizontal direction to prevent the driven sliders from disengaging from the left and right ends of the rectangular frame. The purpose of setting the return spring is to assist the driven slider to clamp the slide post fixing bolt. When the active slider moves upward to the upper end of the rectangular frame, the driven slider slides upward accordingly and is forced to separate to both sides as the position rises. At this time, the operator needs to apply an external force to press the return spring, and the two driven sliders separate, and the slide post fixing bolt is loosened. When the active slider moves towards the bottom plate, the return spring loses the extrusion force of the external force and starts to reset. The two return springs squeeze the two driven sliders towards the middle position, thereby clamping the slide post fixing bolt. The purpose of setting the return spring is to give an inward extrusion force to the driven slider so that it can gather towards the middle position to ensure that the slide post fixing bolt is clamped. The bottom plate has a certain thickness, and a through mounting hole is provided at the center of the bottom plate for installing the telescopic assembly. The ball bearing for installing the telescopic assembly is fixedly installed above the mounting hole, and the upper end of the handrail housing of the telescopic assembly is fixedly installed below.

[0011] Furthermore, the clamping block assembly includes an active slider and two driven sliders. The active slider is of an isosceles trapezoid structure. A connection hole is provided at the center of the bottom surface of the active slider. The upper end of the telescopic assembly is threadedly connected to the connection hole. The active slider is slidably sleeved in the fixing bracket in a limited manner, and the lower bottom edge of the active slider is adjacent to the bottom plate. Dovetail blocks are convexly provided on the end faces of the two waists of the active slider, and the two driven sliders are slidably connected to the end faces of the two waists of the active slider in a limited manner.

[0012] The clamping block assembly includes a driving slider and two driven sliders. The driving slider is a block structure in the shape of an isosceles trapezoid. A connecting hole is provided at the center of its bottom surface. The upper end of the telescopic assembly extends out of the connecting hole and is threadedly connected to the connecting hole of the driving slider. The telescopic assembly can drive the driving slider to slide up and down in the fixed frame. Through holes are respectively provided on the end faces of the two waists of the driving slider, and mating dovetail grooves are provided on the end faces of the two driven sliders in contact therewith. The two driven sliders can be limited to slide on the end faces of the two waists of the driving slider. The front ends of the two driven sliders are rectangular and can clamp or loosen the slide post fixing bolt.

[0013] Further, each driven slider includes a clamping portion, a connecting portion and a rubber block. The clamping portion is a rectangular block structure, and the connecting portion is a right trapezoidal block structure. The end face where the short side of the clamping portion is located is arranged on the end face where the right-angle side of the connecting portion is located to form an integral structure. Rectangular limiting protrusions are provided on the end faces of the connecting portion opposite to the upper horizontal sides of the two rectangular frames.

The outer side walls of the two clamping portions are elastically in contact with the corresponding return springs.

[0014] Each driven slider includes a clamping portion, a connecting portion and a rubber block. The clamping portion and the connecting portion are an integral structure. The clamping portion is a rectangular block structure and mainly functions to clamp the slide post fixing bolt. The connecting portion is mainly slidably connected to the driving slider and the rectangular frame in a limited manner to enable the driven slider to tighten or loosen under the drive of the driving slider. The rubber block is bolted to the clamping portion and can protect the surface of the slide post fixing bolt from being scratched and damaged after being clamped by the clamping portion, thus affecting anti-corrosion and aesthetics. The shape of the connecting portion is a right trapezoidal block. The short side end face of the clamping portion and the straight side end face of the connecting portion are connected to form an integral structure. The side wall of the long side of the clamping portion and the lower bottom end face of the connecting portion form a rectangular end face. Rectangular limiting protrusions are provided on the end faces of the connecting portion opposite to the upper horizontal sides of the two rectangular frames. The limiting protrusions are slidably connected in a limited manner in the grooves on the upper horizontal sides of the rectangular frames. When the driving slider is driven by the telescopic assembly to move towards the upper opening of the fixed frame, the driven slider slides downward from the two waists of the driving slider due to the limitation of the limiting protrusions and the grooves, and the two clamping portions and the corresponding rubber blocks are separated from each other towards the left and right ends, realizing the function of the clamping portions of the two driven sliders to loosen the slide post fixing bolt. When the telescopic assembly drives the driving slider to move downward, the driven slider is squeezed by the return spring and slides towards the middle to gather, realizing the clamping function.

[0018] The front end of the armrest is sleeved and fixed in the ball bearing. The lead screw is sleeved in the front cylindrical part of the armrest. A ball circulator is provided between the lead screw and the armrest of the adjustable armrest. The ball bearing and the armrest move circumferentially together.
