Ventilation and water injection detector for engine block

Abstract

The invention relates to a ventilation and water injection detector for an engine block. An airtightness detecting seat is mounted on a rack. The bottom of the airtightness detecting seat is providedwith a bottom supporting device that cooperates with the engine block, the upper portion is provided with the lifting device for the airtightness detecting, and the side is provided with a side clampthat cooperates with the engine block on the bottom supporting device. The airtightness detecting device that cooperates with the engine block is connected below the lifting device for the airtightness detecting. The bottom supporting device comprises a bottom supporting block provided on the airtightness detecting seat. The bottom supporting plate is provided with a bottom sealing block. The bottom sealing block is provided with a sealing hole with an interference fit with the lower end of the engine block. The detector can not only seal the bottom of the engine block, but also position the engine block, so that the detector and the detecting device provided on the lifting device for the airtightness detecting are accurately and automatically docked, thereby improving the efficiency and the precision of the detection.

[0007] Most of the existing engine block airtightness testing is carried out on the airtightness testing table, that is, the lower opening of the engine block is sealed first, then the engine block is placed on the airtightness testing table, and then The sealing cover with the detection head of the air tightness tester is sealed with the upper end of the engine block, and then the engine is tested by the air tightness tester. Most of the engine testers are docked manually, resulting in a long time for docking. At the same time, the accuracy of the docking is poor, which easily affects the air tightness detection accuracy of the engine
