Description

Rear air bag leakage test device

Technical Field

The utility model belongs to the technical field of the bumper shock absorber, specifically speaking especially relates to a back gas pocket leakage test device.

Background

The air spring shock absorber is one of important auxiliary parts in the vehicle suspension, and the operating principle of the air spring shock absorber is that pressure air is added into a flexible closed container, and the resilience of the compressed air is utilized to provide elasticity, so that shock absorption and buffering are realized.

The prior art relies on the artifical frock that uses the simplex position, puts into the water tank with the gas package and carries out the leak test, and its shortcoming that exists is: the safety precaution is low, the leakage testing efficiency is low, and the labor intensity is high.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome prior art not enough, provide a back gas bag leakage test device, its easy operation, efficient, the commonality is high and the security is high, and the high-pressure leakproofness of product is good.

In order to realize the purpose, the utility model discloses an adopt following technical scheme to realize:

the utility model provides a back gas pocket leakage test device, includes the water tank frame, installs the water tank on the water tank frame, be equipped with frame and internal frame in the water tank, the frame is through sinking mechanism and internal frame connection, is equipped with more than one mounting panel and more than one gas pocket rack on the internal frame, install revolving cylinder on the mounting panel.

Preferably, the sinking mechanism comprises an air cylinder and a sliding rod, the fixed end of the air cylinder is installed on the frame, a cylinder rod of the air cylinder is arranged downwards and is connected with the inner frame, the inner frame is provided with a linear bearing, the upper end of the sliding rod penetrates through the frame, the middle of the sliding rod penetrates through the linear bearing and the inner frame, and the lower end of the sliding rod is installed on the frame.

Preferably, two sides of the inner frame are respectively provided with a clamping groove, and two ends of the mounting plate are respectively mounted on the two clamping grooves.

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

1. the inner frame is lifted up and down through the sinking mechanism so as to place the product into the water tank, and the device has the advantages of simple structure, good guidance performance and high universality;

2. the product is pressed or loosened through the rotary air cylinder, so that the operation is convenient, simple and rapid;

3. the inner frame is clamped into the clamping groove, the distance between the rotary air cylinder and the air bag placing frame can be adjusted at any time according to the size of a product, and the air bag placing frame is simple, convenient and easy to operate;

to sum up, the utility model discloses easy operation, efficient, commonality are high and the security is high, and product high pressure leakproofness is good.

Drawings

Fig. 1 is a first schematic structural diagram of the present invention;

fig. 2 is a second schematic structural diagram of the present invention.

In the figure: 1. a water tank frame; 2. a water tank; 3. a frame; 4. a linear bearing; 5. a slide bar; 6. an inner frame; 7. a cylinder; 8. a rotating cylinder; 9. mounting a plate; 10. placing a gas bag; 11. a clamping groove.

Detailed Description

The present invention will be further described with reference to the following specific embodiments and accompanying drawings.

Example 1:

as shown in fig. 1-2, a back air pocket leakage test device comprises a water tank frame 1, wherein a water tank 2 is installed on the water tank frame 1, a frame 3 and an inner frame 6 are arranged in the water tank 2, the frame 3 is connected with the inner frame 6 through a sinking mechanism, more than one mounting plate 9 and more than one air pocket placing frame 10 are arranged on the inner frame 6, every two air pocket placing frames 10 are installed between every two mounting plates 9, and a rotary air cylinder 8 is installed on each mounting plate 9.

Example 2:

the utility model provides a back gas pocket leakage test device, the mechanism that sinks includes cylinder 7 and slide bar 5, the stiff end of cylinder 7 is installed on frame 3, and the jar pole of cylinder 7 sets up downwards, and jar pole and internal frame 6 connection are equipped with linear bearing 4 on the internal frame 6, and frame 3 is passed to the upper end of slide bar 5, and linear bearing 4 and internal frame 6 are passed to the centre, and the lower extreme is installed on frame 3.

Two sides of the inner frame 6 are respectively provided with a clamping groove 11, and two ends of the mounting plate 9 are respectively mounted on the two clamping grooves 11. The other portions are the same as in example 1.

The utility model discloses a theory of operation does:
