Description

Technical Field

[0001] This utility model relates to the technical field of automotive shock absorbers, and in particular to a tooling for pressing oil seals of automotive shock absorbers. Background Technology

[0002] Shock absorbers are mainly used to suppress the oscillations when the spring absorbs shock and the impact from the road surface. When passing over uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping.

[0003] Existing shock absorber oil seal press-fitting fixtures, such as the shock absorber oil seal press-fitting device disclosed in utility model patent application number 201721852005.2, mainly include a workbench, a clamping mechanism mounted on the workbench, a pressing mechanism mounted on the workbench via a bracket, and a foot switch electrically connected to the clamping mechanism and the pressing mechanism respectively. The workbench has a tray fixed on its surface, and the clamping mechanism includes two pneumatic push rods. In use, the shock absorber assembly with the pre-installed oil seal is placed face down on the tray. When the operator steps on the foot switch, the controller controls the two pneumatic push rods of the clamping mechanism to move, causing the clamping block to move towards the shock absorber assembly, so that the outer cylinder of the shock absorber is located between the two outer mold grooves, fixing the shock absorber assembly on the workbench. Then, the pneumatic telescopic rod of the pressing mechanism is controlled to move, driving the guide frame to move downward along the guide rail on the bracket, thereby causing the copper sleeve and rubber tube to descend, pressing the oil seal fitted on the end of the shock absorber piston rod into the outer cylinder.

[0004] However, most existing pressing fixtures are difficult to press continuously, requiring workers to install and remove them, resulting in low work efficiency. Moreover, it is difficult to inspect the pressing effect after pressing, and it is difficult to visually detect problems such as oil seal lip deformation, which can easily affect subsequent use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automotive shock absorber oil seal press-fitting fixture that not only facilitates continuous press-fitting of shock absorbers and improves press-fitting efficiency, but also allows for the detection of the press-fitting effect of shock absorbers, preventing defective products from entering the market.

[0006] This utility model discloses a tooling for pressing oil seals on automotive shock absorbers, including a feeding mechanism; it also includes a conveying mechanism, multiple fixing mechanisms, a pressing mechanism, and a testing mechanism. The conveying mechanism is installed on the feeding mechanism and drives the shock absorber to move. The multiple fixing mechanisms are all installed on the conveying mechanism and fix the shock absorber. The pressing mechanism is installed on the feeding mechanism and presses the shock absorber. The testing mechanism is installed on the feeding mechanism and tests the pressing effect. The operator places the shock absorber on the fixing mechanism and fixes it. The conveying mechanism drives the conveying mechanism to move forward. The pressing mechanism presses the shock absorber. The testing mechanism tests the pressed shock absorber to ensure the pressing effect of the oil seal. The feeding mechanism drives the pressed shock absorber to unload.

The bottom of the workbench is connected to the ground, the unloading channel is installed on the workbench, the rubber baffle is installed on the workbench, and the shock-absorbing pad is laid on the unloading channel. After the shock absorber flips over, it falls onto the shock-absorbing pad under the action of gravity. The impact force of the shock absorber falling is reduced by laying the shock-absorbing pad. The rubber baffle is set to block the shock absorber that has not fallen from the fixed mechanism, forcing the shock absorber to fall. The shock absorber slides down the unloading channel and is discharged.

The conveyor belt drives the fixing mechanism to convey forward, and the multiple sets of support rollers support the conveyor belt. When the shock absorber moves directly below the pressing mechanism, the two sets of first electric cylinders are activated, and the two sets of first electric cylinders push the top plate against the conveyor belt to prevent the fixing mechanism from descending during the pressing process.

[0009] Preferably, the fixing mechanism includes a base, a positioning plate, a connecting plate, two sets of springs, and two sets of clamping plates. The base is installed on the conveyor belt, the positioning plate is installed on the base and has a positioning groove, the connecting plate is installed on the base and has a positioning hole, the two sets of springs are installed on the base, and the two sets of clamping plates are respectively installed on the two sets of springs.

When the sensor detects that the shock absorber has moved directly under the pressing seat, the hydraulic cylinder is activated, and the hydraulic cylinder pushes the U-shaped frame and the pressing seat down to press the shock absorber oil seal. By setting two sets of guide columns to guide the U-shaped frame, the pressing seat is pressed accurately.

[0011] Preferably, the testing mechanism includes a support frame, a display screen, a servo motor, a reducer, a drive shaft, an arc plate, and three sets of cameras.
