Description

Technical Field

[0001] This utility model relates to the field of automotive pipe fitting testing technology, and in particular to an automotive pipe airtightness testing fixture. Background Technology

[0002] Tubes are essential components in automotive parts. After production, tubes must undergo airtightness testing. Generally, airtightness testing involves first fixing both ends of the tube with tooling fixtures and then sealing and inflating it. The air pressure is used to determine whether it is sealed. However, tubes are not easy to position during the testing process. Therefore, various auxiliary fixtures are needed to fix automotive tubes in the correct position during the testing process.

[0003] Existing pipe clamping and positioning devices can only clamp automotive pipes of the same specifications because the curvature of the clamping arc plate is mostly fixed. At the same time, existing clamps cannot seal automotive pipes, which can easily lead to air leakage during testing. Therefore, this application proposes an automotive pipe airtightness testing clamp. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive pipeline airtightness testing fixture to solve the above-mentioned problems. By setting an expansion clamping component inside the connecting pipe, the pipeline can be expanded and clamped, and it can also adapt to pipelines of different specifications to improve the flexibility of use. By using a rubber sleeve in conjunction with a sealing gasket, the inside of the pipeline can be sealed and the port can be sealed to achieve double sealing and prevent gas leakage during testing, thus solving the problems mentioned in the background art.

[0005] To address the above problems, this utility model provides a technical solution:

[0006] An automotive pipeline airtightness testing fixture includes a base pipe, a slip ring, a rubber sleeve, and an expansion clamping assembly. The slip ring is slidably connected to the outside of the base pipe, and a fixing ring is fixedly connected to the outside of the base pipe. A rubber sleeve is fixedly connected to the outside of the base pipe and located between the slip ring and the fixing ring. A sealing gasket is embedded inside the slip ring and on the side closest to the rubber sleeve. A connecting pipe is fixedly connected to one end of the base pipe, and an expansion clamping assembly for fixing the pipeline is provided inside the connecting pipe.

[0007] As a preferred embodiment of this utility model, an outer cover is fixedly connected to the outside of the base pipe and to the side of the slip ring away from the fixed ring. A first electric telescopic rod is fixedly connected to the outside of the outer cover, and the telescopic end of the first electric telescopic rod is fixed to one side of the slip ring.

[0008] As a preferred embodiment of this utility model, an air pipe is fixedly connected inside the base pipe, and one end of the air pipe passes through the base pipe and is fixedly connected to a quick connector.

[0009] As a preferred embodiment of this utility model, the connecting tube has an air inlet inside, and the end of the air tube away from the quick connector extends into the connecting tube.

[0010] As a preferred embodiment of this utility model, the expansion clamping assembly includes a second electric telescopic rod, which is fixed to one side of the inner wall of the connecting pipe. The telescopic end of the second electric telescopic rod is fixedly connected to a connecting rod, and the two ends of the connecting rod are symmetrically rotatably connected to a pull rod. Two movable rods are symmetrically slidably connected inside the connecting pipe. One end of each of the two movable rods extends to the outside of the connecting pipe and is fixedly connected to an arc-shaped plate. The ends of the two movable rods away from the arc-shaped plate extend into the inside of the connecting pipe and are rotatably connected to the pull rod.

[0011] The beneficial effects of this utility model are as follows: the expansion clamping component set inside the connecting pipe can expand and clamp the pipe, preventing the pipe from disengaging during testing. The expansion clamping component can also adapt to pipes of different specifications, thereby improving the flexibility of use. By squeezing the rubber sleeve with the slip ring and the fixing ring, the rubber sleeve can be bulged, thereby sealing the inner wall of the pipe. The sealing gasket on one side of the slip ring can seal the pipe end, preventing air leakage during air tightness testing. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0018] Please see Figure 1-3Figure 1 shows a technical solution provided by this utility model: a vehicle pipeline airtightness testing fixture, including a base pipe 1, a slip ring 2, a rubber sleeve 4, and an expansion clamping assembly 11. The slip ring 2 is slidably connected to the outside of the base pipe 1, and a fixing ring 3 is fixedly connected to the outside of the base pipe 1. A rubber sleeve 4 is fixedly connected to the outside of the base pipe 1 and located between the slip ring 2 and the fixing ring 3. A sealing gasket 5 is embedded inside the slip ring 2 and on the side close to the rubber sleeve 4. The rubber sleeve 4 and the sealing gasket 5 can seal the inside of the pipeline and seal the port, achieving double sealing and preventing gas leakage during testing. A connecting pipe 10 is fixedly connected to one end of the base pipe 1, and the expansion clamping assembly 11 for fixing the pipeline is provided inside the connecting pipe 10.

[0019] Furthermore, an outer cover 6 is fixedly connected to the outside of the base pipe 1 and to the side of the slip ring 2 away from the fixed ring 3. A first electric telescopic rod 7 is fixedly connected to the outside of the outer cover 6. The telescopic end of the first electric telescopic rod 7 is fixed to one side of the slip ring 2, which can drive the slip ring 2 to move, thereby squeezing the rubber sleeve 4 to achieve the effect of sealing the inner wall of the pipe.

[0020] Furthermore, an air pipe 8 is fixedly connected inside the base pipe 1. One end of the air pipe 8 passes through the base pipe 1 and is fixedly connected to a quick connector 9. An air inlet 12 is opened inside the connecting pipe 10. The end of the air pipe 8 away from the quick connector 9 extends into the interior of the connecting pipe 10. It can be connected to the air supply pipeline through the quick connector 9. Under the action of the air pipe 8, gas can be transported and discharged from the connecting pipe 10 into the pipeline to be tested through the air inlet 12, thereby testing the air tightness of the pipeline.

[0021] Furthermore, the expansion clamping assembly 11 includes a second electric telescopic rod 111, which is fixed to one side of the inner wall of the connecting pipe 10. The telescopic end of the second electric telescopic rod 111 is fixedly connected to a connecting rod 112. The two ends of the connecting rod 112 are symmetrically rotatably connected to a pull rod 114. Two movable rods 113 are symmetrically slidably connected inside the connecting pipe 10. One end of each movable rod 113 extends to the outside of the connecting pipe 10 and is fixedly connected to an arc-shaped plate 115. The ends of each movable rod 113 away from the arc-shaped plate 115 extend into the connecting pipe 10 and are rotatably connected to the pull rod 114. This allows for expansion clamping of the pipe, preventing loosening when pressurizing the inside of the pipe. The arc-shaped plate 115 can also move different distances to adapt to pipes of different specifications, thereby improving the flexibility of use.

[0022] In summary: When using this device, first insert the connecting pipe 10 into the pipe to be tested, and also place the rubber sleeve 4 into the pipe. Then, push the slip ring 2 inside the outer cover 6 by the first electric telescopic rod 7. At this time, under the action of the fixed ring 3, the slip ring 2 squeezes the rubber sleeve 4, such as... Figure 2As shown, the rubber sleeve 4 swells up and seals the inside of the pipe. At the same time, the sealing gasket 5 on one side of the slip ring 2 contacts the pipe end and seals it. Then, the connecting rod 112 is moved by the second electric telescopic rod 111. The movement of the connecting rod 112 drives the pull rod 114 to rotate. At this time, the pull rod 114 pushes the movable rod 113 to the outside of the connecting pipe 10, thereby causing the arc plate 115 to contact the inner wall of the pipe, realizing the expansion clamping of the pipe and avoiding loosening when pressurizing the inside of the pipe. It is connected to the gas supply pipe through the quick connector 9. Under the action of the gas pipe 8, the gas can be transported and discharged from the connecting pipe 10 into the pipe to be tested through the gas inlet 12, thereby testing the air tightness of the pipe.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
