Description

Technical Field

[0001] The utility model relates to the technical field of tooling for sealing inspection of automobile intercoolers, in particular to a novel pneumatic pipe opening expansion plug for sealing inspection. Background Art

[0002] The automobile intercooler group is a key component of the internal combustion engine, which can improve the power of the internal combustion engine and reduce emissions. Its sealing is an important technical indicator. During the sealing inspection, it is necessary to use tooling to seal the inlet and outlet of the air pipe. The traditional sealing methods include manual internal expansion sealing and external clamping sealing. The manual internal expansion type has low production efficiency and high labor intensity; the external clamping type has strict requirements on the size of the air chamber, high manufacturing cost, and small trial range. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a novel pneumatic pipe port expansion plug for sealing inspection, which solves the problems mentioned in the above background technology.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a new type of pneumatic pipe mouth expansion plug for sealing inspection, including a standard thin cylinder, a support body is fixedly arranged on the outer surface of the output end of the standard thin cylinder, and a support plate is fixedly arranged on the bottom of the support body.

[0005] Preferably, the outer surface of the support plate is sleeved with a high-elastic rubber plug, and the high-elastic rubber plug is connected to the bottom of the support body.

[0006] Preferably, the novel pneumatic pipe opening expansion plug for sealing inspection further comprises an air chamber pipe opening, and the air chamber pipe opening is sleeved on the outer surface of the support body.

[0007] Preferably, an annular clamping groove is provided on the outer surface of the support body, and one end of the air chamber pipe opening is clamped into the clamping groove.

[0008] Beneficial Effects

[0009] The utility model provides a new type of pneumatic pipe opening expansion plug for sealing inspection. Compared with the prior art, the utility model has the following beneficial effects: the new type of pneumatic pipe opening expansion plug for sealing inspection adopts a standard thin cylinder, which is connected to a support plate through a support body. When the standard thin cylinder is pulled back, the high elastic rubber is squeezed, and tension and friction are formed on the air chamber pipe opening, thereby completing the plugging of the air chamber pipe opening.

[0010] In summary, the technical solution adopts a standard thin cylinder with low cost, and the high-elastic rubber can obtain a larger deformation amount through tensioning, and can adapt to the sealing of air chamber pipe openings with a larger size range. BRIEF DESCRIPTION OF THE DRAWINGS
