Description

Technical Field

[0001] The utility model relates to a shock absorber sealing machine, in particular to a rolling sealing device of a shock absorber sealing machine. Background Art

[0002] During the driving of an automobile, in order to accelerate the attenuation of the vibration of the vehicle frame and the vehicle body and improve the ride comfort of the automobile, the shock absorber plays a key role. During the processing of the shock absorber, a shock absorber sealing machine is usually used to bend the upper end of the oil storage cylinder of the shock absorber inward to the upper end face of the skeleton oil seal of the shock absorber, and the internal structure of the shock absorber is fixed through the bent part of the oil storage cylinder of the shock absorber.

[0003] The traditional shock absorber sealing machine includes a machine frame, a lifting mechanism installed on the machine frame, a rotating mechanism installed on the lifting mechanism, a supporting mechanism and a side pushing mechanism installed on the machine frame above the rotating mechanism. During the sealing operation, first, the shock absorber is vertically installed on the rotating mechanism, the lifting mechanism is started to move the upper end of the oil storage cylinder of the shock absorber upward between the supporting mechanism and the side pushing mechanism, the outer cylindrical surface of the oil storage cylinder of the shock absorber is supported by the supporting mechanism, then the rotating mechanism is started to drive the shock absorber to rotate horizontally, and then the side pushing mechanism is started to lean against the upper end of the oil storage cylinder of the shock absorber, and the side pushing mechanism bends the upper end of the oil storage cylinder of the shock absorber inward to the upper end face of the skeleton oil seal of the shock absorber to realize the shock absorber sealing operation.

[0004] This kind of shock absorber sealing machine has the following problems: the bending point of the oil storage cylinder of the shock absorber is adjusted by the lifting mechanism of the shock absorber sealing machine, and the operator adjusts the lifting mechanism according to the naked eye, so the bending point of the oil storage cylinder of the shock absorber is not accurately controlled. When the bending point is low, the side pushing mechanism interferes with the skeleton oil seal of the shock absorber; when the bending point is high, there is a gap between the bent part and the skeleton oil seal, resulting in loose sealing of the shock absorber. Summary of the Invention

[0005] The utility model is to solve the above technical problems and provides a rolling sealing device of a shock absorber sealing machine. During the shock absorber sealing operation, the bending point is accurately controlled, which not only avoids the interference of the sealing action but also ensures the firm sealing of the shock absorber.

[0006] The technical solution of the utility model is as follows:

[0007] A rolling sealing device of a shock absorber sealing machine includes an annular mounting seat, and a connecting seat is fixedly installed on the upper end surface of the mounting seat. The special feature is that a plurality of axles and rollers distributed circumferentially are respectively arranged in the mounting seat, the axles and the rollers are arranged alternately, the axles extend in the radial direction and are circumferentially rotatably installed on the mounting seat, a rolling head is arranged on the inner end surface of the axle, the rolling head is a conical surface with a narrow inner part and a wide outer part, and the rollers extend in the up and down direction and are horizontally rotatably installed on the mounting seat.

[0008] Further, a bearing seat equal in number to the rotating shafts is fixedly installed on the outer cylindrical surface of the mounting seat, and the rotating shafts are installed on the corresponding bearing seats through bearing groups.

[0009] Further, an oil injection hole is provided on the rotating shaft between the outer end face and the bearing group, and grease is injected into the bearing group through the oil injection hole.

[0010] Further, an oil filling nozzle is fixedly installed at the outer end of the oil injection hole, and a grease gun is used to inject grease into the bearing group through the oil filling nozzle.

[0011] Further, a smooth transition is provided between the rolling head and the rotating shaft to prevent the oil storage cylinder of the shock absorber from getting stuck during the rolling sealing process.

[0012] The beneficial effects of the present utility model are as follows:

[0013] Multiple rollers support the outer cylindrical surface of the oil storage cylinder of the shock absorber to ensure the coaxiality of the shock absorber. During the process of the lifting mechanism of the shock absorber sealer driving the shock absorber to move upward and the rotating mechanism of the shock absorber sealer driving the shock absorber to rotate horizontally, under the action of the lateral component force of the conical surface of the rolling head, the upper end of the oil storage cylinder of the shock absorber is gradually rolled and bent inward. By replacing the traditional lateral feeding method with a feeding method from top to bottom, until the bent part at the upper end of the oil storage cylinder of the shock absorber abuts against the upper end face of the skeleton oil seal of the shock absorber, the bending point is accurately controlled, which not only avoids the interference of the sealing action but also ensures the firm sealing of the shock absorber.
