Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber sleeve technology, and more specifically, to an automotive shock absorber sleeve press-fitting device. Background Technology

[0002] Automotive shock absorbers are used as dampers on vehicle bumpers. Automotive shock absorbers are generally equipped with sleeves, which play a significant role in the shock absorber's operation. During the manufacturing process, the sleeves are assembled onto the surface of the automotive shock absorber using a press-fitting device to facilitate later use.

[0003] For example, CN113878332A discloses an automatic pressing device for automotive shock absorbers. The key technical points of this device are: it includes a body, an electric slide rail, a hydraulic cylinder, and a base. The electric slide rail is located on the left and right sides of the inner cavity of the body. The hydraulic cylinder is fixedly connected to the top of the inner cavity of the body by bolts. The base is located at the bottom of the inner cavity of the body. Adjustable feet are fixedly connected to the four corners of the bottom of the body. Doors are rotatably connected to the left and right sides of the front sidewall of the body via hinges, and observation windows are provided on the upper side of the front sidewall of both doors. An exhaust port is provided on the right sidewall of the body. The left and right sides of the inner cavity of the body... The device has a first mounting slot on each side, and the electric slide rail is fixedly connected inside the first mounting slot. The controller is fixedly connected to the right side wall of the machine body by bolts. It mainly rotates the adjusting bolts on both sides of the positioning sleeve, thereby driving the arc plate at the connecting end of the adjusting bolt to move horizontally inside the positioning sleeve. This allows the working space inside the positioning sleeve to be expanded and contracted, so that the working size of the positioning sleeve can be adjusted according to the size of the bushing. This eliminates the need for repeated replacement of the positioning sleeve by the operator, fundamentally reducing the actual operation required and greatly improving the working efficiency of the device.

[0004] The aforementioned automatic pressing device for automotive shock absorbers still has certain shortcomings: due to the different models of automotive shock absorbers, if the model of the automotive shock absorber is smaller than the original fixing range of the fixing component, the automotive shock absorber cannot be fixed, which will affect the pressing work of the device and also affect the pressing accuracy of the device. Therefore, it is necessary to provide an automotive shock absorber sleeve pressing device. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide an automotive shock absorber sleeve pressing device. By setting an adaptive component, when the model of the automotive shock absorber body is smaller than the original fixing range of the fixing component, the bottom end of the automotive shock absorber body is placed in the center inside the adaptive component. Then, multiple sets of second hydraulic telescopic rods are activated simultaneously, causing them to move the arc-shaped connecting plate and the stabilizing suction cup until the side wall of the stabilizing suction cup is in contact with the surface of the automotive shock absorber body. At this point, the automotive shock absorber body can be fixed. Because the second hydraulic telescopic rods have an automatic telescopic function, they can control the size of the area enclosed by multiple sets of arc-shaped connecting plates, thereby adapting to various models of automotive shock absorber bodies, improving the practicality of the device, and solving the problems existing in the prior art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a pressing device for automotive shock absorber sleeves, including a processing base, a pressing component fixedly connected to the top of the processing base, an auxiliary component fixedly connected to the top of the pressing component, an adaptive component fixedly connected to the middle of the top of the processing base, and an automotive shock absorber body disposed inside the adaptive component.

[0007] The press-fit assembly includes a frame, limiting rods, and sliders. Two limiting rods are fixedly connected symmetrically along the top of the frame, and sliders are movably sleeved on the surface of the limiting rods.

[0008] The bottom end of the frame is connected to the top end of the processing base. Two through holes are symmetrically opened along the center of the side wall of the slider. A first hydraulic telescopic rod is fixedly connected to the middle of the side wall of the slider. One end of the first hydraulic telescopic rod is connected to one side of the top of the inside of the frame.

[0009] The bottom end of the slider is fixedly connected to a mounting plate, and the bottom end of the mounting plate is fixedly connected to a plurality of first hydraulic lifting rods in a circular array. The bottom end of each first hydraulic lifting rod is fixedly connected to a pressure ring.

[0010] The adaptive component includes a connecting ring and a second hydraulic telescopic rod. Multiple second hydraulic telescopic rods are fixedly connected in a circular array inside the connecting ring. The bottom end of the connecting ring is connected to the middle of the top end of the processing base.

[0011] One end of the second hydraulic telescopic rod is fixedly connected to an arc-shaped connecting plate. The sidewall of the arc-shaped connecting plate is fixedly connected to multiple stabilizing suction cups in an arc-shaped array. The sidewall of the stabilizing suction cups is in contact with the surface of the car shock absorber body.

[0012] The auxiliary components include an L-shaped connecting block, a stabilizing rod, a conveying cylinder, and a connecting bend. The stabilizing rod is fixedly connected to the middle of the side wall of the L-shaped connecting block. One end of the stabilizing rod is fixedly connected to the conveying cylinder. The bottom end of the conveying cylinder is connected to the connecting bend. The bottom end of the connecting bend is connected to one side of the top of the slider. The bottom end of the side wall of the L-shaped connecting block is connected to the middle of the other side wall of the slider. The inside of the conveying cylinder is filled with lubricating oil.

[0013] The top end of the L-shaped connecting block is fixedly connected to a second hydraulic lifting rod, and the bottom end of the second hydraulic lifting rod is fixedly connected to a piston. The surface of the piston is adapted to the interior of the conveying cylinder.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] 1. In the above solution, the pressing device is equipped with an adaptive component. When the model of the car shock absorber body is smaller than the original fixing range of the fixing component, the bottom end of the car shock absorber body is placed in the center of the adaptive component. Then, multiple sets of second hydraulic telescopic rods are activated simultaneously, causing them to move the arc-shaped connecting plate and the stabilizing suction cup until the side wall of the stabilizing suction cup is in contact with the surface of the car shock absorber body. At this time, the car shock absorber body can be fixed. Because the second hydraulic telescopic rod has an automatic extension and retraction function, it can control the size of the area enclosed by multiple sets of arc-shaped connecting plates, thereby adapting to various models of car shock absorber bodies and improving the practicality of the device.

[0016] 2. In the above scheme, the pressing device is equipped with an auxiliary component. When the friction between the limiting rod and the slider inside the pressing component increases, the second hydraulic lifting rod inside the auxiliary component is activated, causing it to drive the piston to move downward inside the conveying cylinder. Because the surface of the piston is adapted to the inside of the conveying cylinder, the movement of the piston can squeeze the lubricating oil filled inside the conveying cylinder into the two sets of connecting bends. Finally, the connecting bends transport the lubricating oil to the inside of the through hole, thereby lubricating the surface of the limiting rod and the inside of the slider, thus reducing the friction between them and facilitating the operation of the pressing component.

Detailed Implementation

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1:

[0026] Please see Figure 1-5 A pressing device for automotive shock absorber sleeves includes a processing base 1, a pressing assembly 2 fixedly connected to the top of the processing base 1, an auxiliary assembly 3 fixedly connected to the top of the pressing assembly 2, an adaptive assembly 4 fixedly connected to the middle of the top of the processing base 1, and an automotive shock absorber body 5 disposed inside the adaptive assembly 4.

[0027] The press assembly 2 includes a frame 21, a limiting rod 22 and a slider 23. Two limiting rods 22 are fixedly connected symmetrically along the center at the top of the frame 21, and the slider 23 is movably sleeved on the surface of the limiting rod 22.

[0028] The bottom end of frame 21 is connected to the top end of processing base 1. Two through holes 24 are symmetrically opened along the center of the side wall of slider 23. A first hydraulic telescopic rod 25 is fixedly connected to the middle of the side wall of slider 23. One end of the first hydraulic telescopic rod 25 is connected to one side of the top end inside frame 21. A mounting plate 26 is fixedly connected to the bottom end of slider 23. Multiple first hydraulic lifting rods 27 are fixedly connected to the bottom end of mounting plate 26 in a circular array. A pressure ring 28 is fixedly connected to the bottom end of the first hydraulic lifting rod 27. The above arrangement facilitates the adjustment of the position of pressure ring 28, thereby enhancing the practicality of the device. Adaptive component 4 includes connecting ring 41 and second hydraulic telescopic rods 42. Multiple second hydraulic telescopic rods 42 are fixedly connected to the inside of connecting ring 41 in a circular array. The bottom end of connecting ring 41 is connected to the middle of the top end of processing base 1. An arc-shaped connecting plate 43 is fixedly connected to one end of the second hydraulic telescopic rod 42. Multiple arc-shaped connecting rods 43 are fixedly connected to the side wall of arc-shaped connecting plate 43 in an arc array. The stabilizing suction cup 44 has its sidewalls in contact with the surface of the car shock absorber body 5. This arrangement helps ensure the stability of the car shock absorber body 5 during installation. The auxiliary component 3 includes an L-shaped connecting block 31, a stabilizing rod 32, a conveying cylinder 33, and a connecting bend 34. The stabilizing rod 32 is fixedly connected to the middle of the sidewall of the L-shaped connecting block 31. The conveying cylinder 33 is fixedly connected to one end of the stabilizing rod 32. The bottom end of the conveying cylinder 33 is connected to the connecting bend 34. The bottom end of the connecting bend 34 is connected to one side of the top of the slider 23. The bottom end of the sidewall of the L-shaped connecting block 31 is connected to the middle of the other sidewall of the slider 23. The inside of the conveying cylinder 33 is filled with lubricating oil. The top end of the L-shaped connecting block 31 is fixedly connected to a second hydraulic lifting rod 35. The bottom end of the second hydraulic lifting rod 35 is fixedly connected to a piston 36. The surface of the piston 36 is adapted to the inside of the conveying cylinder 33. This arrangement helps reduce the workload of the workers and also facilitates the operation of the pressing component 2.

[0029] The working process of this utility model is as follows:

[0030] To enhance adaptability, the press-fitting device is equipped with an adaptive component 4. When the size of the car shock absorber body 5 is smaller than the original fixing range, the bottom of the car shock absorber body 5 is placed in the center of the adaptive component 4. Then, multiple sets of second hydraulic telescopic rods 42 are activated simultaneously, causing them to move the arc-shaped connecting plate 43 and the stabilizing suction cup 44 until the side wall of the stabilizing suction cup 44 is in contact with the surface of the car shock absorber body 5. At this point, the car shock absorber body 5 can be fixed. Because the second hydraulic telescopic rods 42 have an automatic telescopic function, they can control the size of the area enclosed by multiple sets of arc-shaped connecting plates 43, thereby adapting to various models of car shock absorber bodies 5 and improving the practicality of the device.

[0031] In the above scheme, the pressing device is equipped with an auxiliary component 3 to facilitate the operation of the pressing assembly 2. When the friction between the limiting rod 22 and the slider 23 inside the pressing assembly 2 increases, the second hydraulic lifting rod 35 inside the auxiliary component 3 is activated, causing the piston 36 to move downward inside the conveying cylinder 33. Because the surface of the piston 36 is compatible with the inside of the conveying cylinder 33, the movement of the piston 36 can squeeze the lubricating oil filled inside the conveying cylinder 33 into the two sets of connecting bends 34. Finally, the connecting bends 34 transport the lubricating oil to the inside of the through hole 24, thereby lubricating the surface of the limiting rod 22 and the inside of the slider 23, reducing the friction between them, and facilitating the operation of the pressing assembly 2.
