Description

Technical Field

[0001] The utility model relates to the technical field related to shock absorber processing, in particular to a shrinking device for a shock absorber tube of an automobile. Background Art

[0002] The function of automobile shock absorbers is to suppress the shock caused by the rebound of the spring after shock absorption and the impact from the road surface. When passing through 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 jump. The main components of the shock absorber are the oil storage pipe, high-pressure pipe, piston pipe and compression valve. Among them, the processing procedures of the oil storage pipe and the high-pressure pipe are basically the same, but the oil storage pipe needs to be shrinked at the bottom of the pipe, so that a larger oil storage pipe can be placed in the shock absorber to hold more oil.

[0003] At present, since the shrinking of pipe fittings is usually achieved by extruding the outside of the pipe fittings, and the pipe fittings are easily scratched or worn due to friction during the extrusion process, it is necessary to lubricate the pipe fittings with oil before shrinking. However, the shrinking device in the prior art usually adopts the oil spraying method to oil the pipe fittings. However, this oiling method not only causes the oil to fly everywhere and cause unevenness, but also causes excessive oiling and oil dripping. The dripping oil not only causes waste, but also pollutes the machine. The oil spraying effect is poor. Secondly, the shrinking device in the prior art usually loads and unloads the pipe fittings manually, which leads to a high labor intensity for the staff and a low degree of automation. Utility Model Content

[0004] The utility model aims to provide a shrinking device for a shock absorber tube of an automobile, so as to solve the problem that the shrinking device in the prior art proposed in the above background technology usually adopts the oil spraying method to oil the pipe fittings, but this oiling method not only causes the oil to fly everywhere and cause unevenness, but also causes excessive oiling and causes oil dripping. Secondly, the shrinking device in the prior art usually loads and unloads the pipe fittings manually, which leads to the problem of high labor intensity of the staff.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a shrinking device for a shock absorber tube of an automobile, comprising a frame,

[0006] A loading box is fixed on the top of the frame, and a silo is provided at one end of the loading box, a guide groove is provided at the bottom of the side of the silo, a circular groove is provided at the other end of the loading box, and the circular groove is connected with the guide groove, a loading tray is provided in the circular groove, and an arc-shaped notch is provided on the side of the loading tray, a rubber pad is fixed on the upper inner wall of the circular groove, a driving device is provided at the rear end of the loading box, and the output end of the driving device is connected to the loading tray;

[0007] An oiling mechanism is provided on the outer side of the feeding box, and a shrinking mechanism is provided on the frame;

[0008] A pipe fixing mechanism is arranged on the side of the loading box.

[0009] In the above technical solution, the outer side of the pipe port can be evenly oiled, thereby avoiding uneven oiling. The rotation of the pipe does not require an additional driving source, which facilitates maintenance and reduces production costs.

[0010] Preferably, the rubber pad is arc-shaped, and inclined surfaces are provided on both sides of the rubber pad.

[0011] In the above technical solution, the inclined surfaces on both sides of the rubber pad can avoid obstruction between the pipe fitting and the rubber pad, so that the pipe fitting can contact the rubber pad smoothly.

[0012] Preferably, the oiling mechanism includes an oil tank, which is fixed to the front end of the feeding box, and an oil absorption pad is provided at the bottom of the oil tank. A refueling pipe is also provided at the top of the oil tank. The oil absorption pad is arc-shaped and is level with the rubber pad.

[0013] In the above technical solution, the oil tank can be refueled through the refueling pipe, and the lubricating oil in the oil tank will penetrate from the oil outlet to the oil absorption pad, which can absorb the oil. When the loading plate drives the pipe fittings in the arc-shaped notch to rotate counterclockwise, the pipe fitting ports in the arc-shaped notch will contact the oil absorption pad at the bottom of the oil tank, thereby realizing the oiling operation. Moreover, this oiling method will not cause excessive oiling and cause oil dripping to cause waste, and it has a better oiling effect on the pipe fittings.

[0014] Preferably, the necking mechanism comprises a fixing plate, the fixing plate is fixed on the frame, and a hydraulic cylinder 1 is fixed through the top of the fixing plate, and a necking device is provided at the output end of the hydraulic cylinder 1.

[0015] In the above technical solution, after the pipe fittings in the silo are introduced from the guide groove into the arc-shaped notch on the side of the loading tray, as the loading tray rotates 180°, the oiled pipe fittings will rotate to align with the necking device. After that, the pipe fittings can be fixed by the pipe fixing mechanism, and the necking device can be extended by the hydraulic cylinder on the fixing plate, so that the necking device can neck the port of the pipe fitting.

[0016] Preferably, a material discharge chute is provided at the bottom of the circular trough and on the frame, and a collection box is provided below the material discharge chute.

[0017] In the above technical solution, after the pipe fittings in the arc-shaped notch on the side of the loading tray are shrunken, as the loading tray rotates, the shrunken pipe fittings will fall from the unloading chute to the collection box for collection, so that the shrunken pipe fittings can be unloaded.

[0018] Preferably, the pipe fixing mechanism includes a second hydraulic cylinder, the second hydraulic cylinder is arranged through the side of the loading box, and a clamping plate is arranged at the output end of the second hydraulic cylinder, and the clamping plate is arc-shaped.

[0019] In the above technical solution, when the pipe fittings in the silo are introduced from the guide groove into the arc-shaped notch on the side of the loading tray, as the loading tray rotates 180°, the pipe fittings will be aligned with the clamping plate, and then the clamping plate can be driven to extend by the second hydraulic cylinder, so that the clamping plate can clamp and fix the pipe fittings in the arc-shaped groove, avoiding the displacement of the pipe fittings during shrinking, thereby improving its practicality.

[0020] Compared with the prior art, the utility model has the following beneficial effects: the automobile shock absorber necking device is

[0021] (1) The feeding plate is driven to rotate by a driving device, so that the feeding plate can drive the pipe fittings in the arc-shaped notch to rotate counterclockwise. During the rotation of the feeding plate, the pipe fitting ports in the arc-shaped notch will contact the oil absorption pad at the bottom of the oil tank, so that the outer side of the pipe fitting ports can be oiled. In addition, during the rotation of the feeding plate, the pipe fittings in the arc-shaped notch will be close to the rubber pad at the top of the inner wall of the circular groove. Since the friction between the rubber pad and the pipe fitting is large, the pipe fittings in the arc-shaped notch will automatically rotate during the rotation of the feeding plate, so that uniform oiling can be achieved, and pollution and waste caused by excessive oiling can be avoided, and the oiling effect is better.

[0022] (2) The silo can be used to conveniently stack the pipes. The guide groove at the bottom of the silo can guide the pipes into the arc-shaped notch on the side of the loading tray. The loading tray is then driven to rotate by a driving device, which can drive the pipes to be oiled, shrunken and unloaded in turn. No manual intervention is required during use, and the degree of automation is high. In addition, the multiple sets of arc-shaped notches on the side of the loading tray can achieve the purpose of continuous operation, thereby making the processing efficiency higher.
