TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile accessory testing fixture, especially to an automobile air filter intake pipe testing fixture. BACKGROUND

[0002] Air filter refers to the device for removing particulate impurities in air. If dust and other impurities are contained in the air sucked in during the operation of piston type machinery (internal combustion engine, reciprocating compressor air filter, etc.), the wear of parts will be aggravated. Therefore, an air filter must be installed. The air filter is composed of a filter element and a shell. The main requirements for the air filter are high filtering efficiency, low flow resistance, and long-term continuous use without maintenance. After the automobile air filter intake pipe is processed and formed, the caliber of the pipe opening needs to be detected to determine whether the caliber quality of the pipe opening is qualified.

[0034] In view of the prior art, the clamping part of the gauge is fixed, which is difficult to adapt to different pipe diameters, the clamp needs to be frequently replaced, time-consuming and high in cost, and the detection piece is of a fixed structure and cannot be flexibly adjusted in size, resulting in the need for multiple sets of equipment for different specifications of pipe openings, which is low in efficiency.

[0035] As shown in Figures 1-4 The utility model discloses an automobile air filter inlet pipe gauge, which comprises a base 10, a pushing assembly 20 arranged on the top of the base 10, a cylinder seat 21 of the pushing assembly 20, a pushing cylinder 22 installed on one side of the cylinder seat 21, a pushing plate 23 slidably connected to the top of the base 10, and a limiting sliding rail 24 symmetrically arranged on the upper surface of the base 10 and slidably connected to the bottom of the pushing plate 23.

[0036] When detecting, the pushing cylinder 22 is started to drive the pushing plate 23 to move laterally, and the pushing plate 23 drives the detection assembly 50 on one side to move laterally, so that the detection assembly 50 is inserted into the inner wall of the air filter inlet pipe.
