Embodiment 1

[0040]An air intake blocking mechanism for an air intake pressure test of a motor vehicle engine, comprising: a mobile platform 1 arranged and movable on a fixed bracket; For the plugging heads 3 of the air inlet of the engine under test, the two groups of plugging heads 3 are arranged at an angle of 90°.

[0041] The cylinders 2A, 2B and 2C are arranged on the rear side of the second group of plugging heads 3, the first cylinder 2B is used to push the plugging heads, and the second cylinders 2A-2C drive the intake docking seat 9 to connect with the changing shaft. The pressure sensor 5 and the pneumatic ball valve 6 are arranged on the back side of the plugging head and communicated with the plugging head 3. The intake pressure sensor 5 is used to test the pressure of the engine air inlet, and the pneumatic ball valve 6 is opened according to the test requirements. Or close the passage of the engine exhaust port and the outside atmosphere, which is used to control the breathi...

Abstract

An air inlet blocking mechanism for a motor vehicle engine air inlet pressure test is disclosed and comprises a mobile platform (1), two groups of blocking heads (3) which are arranged on a model-change rotating shaft (10) at one end of the moving platform (1) and are used for blocking an air inlet of the tested engine, air cylinders (2A, 2B and 2C) arranged on the rear sides of the two groups of blocking heads (3), a pressure sensor (5) and a pneumatic ball valve (6) which are both arranged on the rear sides of the blocking heads and are communicated with the blocking heads (3), and a swing air cylinder (8) which is arranged at one end of the model-change rotating shaft (10), , wherein the two groups of the blocking heads (3) are arranged at a certain angle in a spaced manner; the first air cylinder (2B) is used for pushing the blocking heads; the second air cylinders (2A and 2C) drive an air inlet butting seat (9) to be connected with the model-change rotating shaft (10); the swing air cylinder (8) is fixedly connected with the model-change rotating shaft (10) and can rotate. The air inlet blocking mechanism can be used for conveniently switching the blocking heads when the air inlet pressure of engines of multiple models is detected online and engines of different models are changed, and therefore the blocking heads correspond to air inlets of engines of different models.

Description

technical field [0001] The present invention relates to the field of motor vehicle engine testing. Specifically, the present invention relates to an air intake sealing mechanism for motor vehicle engine intake pressure testing. More specifically, the present invention relates to a motor vehicle engine intake pressure testing mechanism. The air intake sealing mechanism, which can be used to detect the intake air pressure of various types of engines online, and conveniently switch the sealing head of the air intake sealing mechanism when changing different types of engines, so as to be compatible with different types of engines corresponding to the air inlet. Background technique [0002] When testing a motor vehicle engine, it is necessary to detect the intake pressure of the engine. At the same time, in order to meet the requirements of online detection of various types of engines, it is necessary to switch the plugging head to correspond to its air inlet. In the past, it ...
