In addition, the invention also provides a method for detecting the performance of the intake manifold of the automobile engine, which comprises the following steps: s1, fixing an intake manifold: firstly, an air inlet manifold to be detected is placed on a receiving column 30 manually, then a connecting plate 312 drives a tight fork plate 315 to synchronously move backwards, then a first air cylinder 316 works to enable a telescopic end of the air cylinder to drive the tight fork plate 315 to move leftwards through an L-shaped block 314, so that all the tight plates 310 and tight strips in the tight fork plate 315 are mutually matched to clamp and fix the upper end face part of the placed air inlet manifold, meanwhile, an electric sliding block works to enable a side plate 11 to drive the air inlet manifold fixedly clamped on the side plate to move to the position right above an upright column 40, and then an external electric push rod works to enable a base plate 2 to move upwards through a movable column to enable the upright column 40 to be inserted into a mounting hole on a mounting plate at an air inlet of the air inlet manifold.
S2, sealing operation: first, the first abutting round table in the upper sealing mechanism 3 moves to the right to the corresponding air outlet in the manifold to be blocked, meanwhile, the second abutting round table 42 in the lower sealing mechanism 4 moves up to the air inlet in the manifold to be blocked, and the two pressing plates 442 compress the mounting plate at the air inlet of the air inlet manifold, and meanwhile, the cover plate 331 rotates positively through the engagement between the driving gear 333 and the teeth, so that the matching groove 332 on the cover plate 331 and the air outlet through groove 330 are staggered, and the air inlet manifold is in a closed state.
S3, high temperature resistance detection: the external air pump pumps high-temperature and colored gas into the intake manifold through the intake pipe, thereby performing high-temperature resistance detection on the intake manifold, and detecting whether the intake manifold is broken due to a high-temperature state by observing whether colored gas is removed from the intake manifold, i.e., whether the high-temperature gas is broken after being flushed into the intake manifold.
S4, detecting the air inlet rate: after the high temperature resistance detection is finished, the matching groove 332 on the cover plate 331 and the air outlet through groove 330 are mutually overlapped by the external motor, so that the air outlet manifold is communicated with the external flowmeter, and the external air pump in the lower sealing mechanism 4 continuously supplies air at the moment, so that the external flowmeter detects the air passing through the air inlet manifold, and the air inlet rate of the air inlet manifold is detected.
