Valve bridge guide pillar and air valve guide sleeve testing fixture and placing equipment thereof

The utility model discloses a valve bridge guide pillar air valve guide sleeve testing fixture and a testing fixture placing device, and relates to the technical field of testing fixtures. The device comprises a fixing plate, wherein a valve bridge guide pillar positioning sleeve and an air valve guide sleeve positioning shaft are arranged on the top surface of the fixing plate in a penetrating manner; according to the utility model, by designing the testing fixture for the valve bridge guide pillar and the air valve guide sleeve, whether the parallelism and the position dimension of the valve bridge guide pillar and the inner hole of the air valve guide sleeve are out of tolerance can be rapidly detected, thereby avoiding the serious consequences of single-side abrasion of the top surface of the air valve, pulling out of the valve bridge guide pillar or cylinder ejection, improving the reliability of an engine, and improving the reliability of the engine. Moreover, the gauge can rapidly detect the size and p
