Reference numerals: 1. a frame; 2. a forward cylinder; 3. a lateral cylinder I; 4. a top cylinder; 5. a lateral cylinder II; 6. a displacement block; 7. a slide rail; 8. and (4) an electric cylinder.

Detailed Description

Example one

As shown in fig. 1, the utility model provides an airtightness testing mechanism, which comprises a frame 1, be provided with the sliding assembly in the frame 1, be provided with the displacement piece 6 that is used for placing the part of waiting to detect on the sliding assembly, the one end of sliding assembly still is provided with determine module.

The sliding assembly includes:

the sliding rail 7 is arranged on the rack 1 and used for placing the displacement block 6;

and the electric cylinder 8 is arranged in parallel with the slide rail 7 and is used for moving the displacement block 6.

Specifically, in this embodiment, the slide rail 7 and the electric cylinder 8 are disposed on the frame 1 in parallel, and are used for preventing the displacement block 6, and when the displacement block 6 is disposed on the slide rail 7 and the electric cylinder 8, the electric cylinder 8 is also used as a power source for moving the displacement block 6, so that the displacement block 6 can move on the slide rail 7 and the electric cylinder 8 to the position to be detected.

The detection assembly in this embodiment includes:

the positive cylinder 2 is positioned at the end part of the slide rail 7, and the output end faces the slide rail 7;

and the lateral cylinder groups are arranged on two sides of the slide rail 7.

Specifically, the lateral cylinder group in the present embodiment includes two lateral cylinders, i.e., a first lateral cylinder 3 and a second lateral cylinder 5.

Specifically, the first lateral cylinder 3 and the second lateral cylinder 5 are used for detecting the sealing performance of the side edge of the oil pump assembly.

And the forward cylinder 2 is used to detect the front tightness of the oil pump assembly.

The detection assembly also comprises a top cylinder 4, assumed at the top of the end of said slide 7.

The first lateral cylinder 3 and the second lateral cylinder 5 are used for detecting whether the part is sealed or not, cylinders are arranged at each detection position, the cylinders are attached to the detection positions after the parts are fixed at the detection positions, air blowing and pressurization are carried out on the parts, and when the pressure value is too small, the part is poor in sealing performance.

Whether top cylinder 4 is arranged in detecting the trompil among the vehicle oil pump part and link up, removes to detecting the position back at displacement block 6, and top cylinder 4 moves, laminates the vehicle oil pump part on the displacement block 6 and blows the pressurization, when carrying out the hole and link up and examine time measuring, aims at the trompil and blows, observes the pressure value, when the pressure value is too big, explains that the hole does not link up.

In this embodiment, two sets of detection equipment with the same structure are arranged on the frame 1, so that the detection efficiency can be improved.

The utility model discloses a theory of operation: the automobile oil pump part to be detected is placed on the displacement block 6, the electric cylinder 8 is started at the moment, the displacement block 6 moves on the electric cylinder 8 and the sliding rail 7, after the automobile oil pump part moves to a preset position to be detected, the electric cylinder 8 stops working, and at the moment, each cylinder (the lateral cylinder I3, the lateral cylinder II 5, the top cylinder 4 and the forward cylinder 2) in the detection assembly starts to run to detect the air tightness of the oil pump. After detection is finished, the electric cylinder 8 reversely runs to drive the displacement block 6 to reversely move on the electric cylinder 8 and the slide rail 7, and the displacement block runs to the initial position to finish detection.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited thereto, and various changes can be made without departing from the gist of the present invention within the knowledge of those skilled in the art.
