Description

End leakage tester

Technical Field

The utility model relates to a bumper shock absorber end leakage test equipment, specifically speaking especially relates to an end leakage test machine.

Background

The end is one of important parts in the air spring shock absorber, the material is iron, aluminum and the like, welding, casting, vulcanization and the like are adopted in an additive and common mode, the end bears the weight of the whole automobile, the requirement on the sealing performance is extremely strict, the connection mode of the end in the air spring shock absorber is a buckling and pressing mode, once air leakage is found after buckling and pressing is finished, the whole air spring needs to be cut, and the cost is high. The area of the end is large, the inflation pressure is high during leakage test, large pressure is generated in the cavity, the end can be conveniently observed only by being placed in water, the end is not in a standard shape, the sealing position is irregular, and the leakage test difficulty is high. In the prior art, a single specific tool is manually used, an O-shaped ring is used for sealing according to a sealing position, an end head is fixed in a bolt and nut screwing mode, and then the tool is put into water for leakage test.

At present, an end leakage tester which is simple in structure, easy to operate, safe, reliable, high in leakage testing efficiency and high in universality is lacking, and the pressure of an air cylinder and a sealing ring are used for sealing.

Disclosure of Invention

An object of the utility model is to provide an end leakage tester to solve and lack a simple structure easy operation among the prior art, adopt the pressure and the sealing washer of cylinder to seal, safe and reliable, the problem of the end leakage tester that the leakage testing is efficient and the commonality is strong.

The utility model discloses a realize through following technical scheme:

an end leakage tester comprises a rack, wherein a motor, a control box, a switch, a slide rail, a lifting mechanism and a water tank are arranged on the rack, the lifting mechanism comprises a fixed plate, an upper plate is arranged above the fixed plate, a lower plate is arranged below the fixed plate, an air cylinder is arranged on the upper plate and connected with a sealing seat, and a fixed seat is arranged on the lower plate; the fixed plate is provided with a slide rail seat, and the slide rail seat is arranged on the slide rail; the motor is connected with the lead screw through the coupler, the lead screw is provided with a lead screw nut, and the lead screw nut is connected with the fixed plate; and a photoelectric switch is arranged on the frame.

Further, the motor is a servo motor.

Further, the fixed plate, the upper plate and the lower plate are in a J-shaped combined component.

Furthermore, a threaded hole is formed in the fixing plate 13, and the upper plate 5 is fixed on the fixing plate 13 through a bolt.

Further, the switch is a foot switch.

Compared with the prior art, the beneficial effects of the utility model are that:

1. in the past, the leakage test by bolts is unsafe and has high danger, and the leakage test efficiency is increased by adopting the matching mode of the fixed seat and the sealing seat, wherein the sealing is tight.

2. Be equipped with the sealing washer on the seal receptacle and can adapt to the end of different grade type, when testing the product of different grade type, only need change the fixing base can be safe high-efficient, the commonality is strong.

3. The automatic detection device is simple to operate, the photoelectric switch can automatically detect the position, the device automatically sinks to place the test piece into water, and an operator can observe the test piece.
