Abstract

The invention discloses an air tightness detecting device for an engine cylinder head and a detecting method of the air tightness detecting device. The air tightness detecting device includes a conveying roller bed and a pressurizing device, the conveying roller bed includes a conveying frame and conveying rollers, and the conveying rollers are installed parallel to each other at intervals on theconveying frame. According to the air tightness detecting device for the engine cylinder head and the detecting method of the air tightness detecting device, through use of the conveying rollers, automatic conveying of the engine cylinder head can be realized, clamping and positioning of a blocking plate are realized through the action of a locking cylinder and a locking head arranged on the conveying frame, and meanwhile, the height of the blocking plate can be adjusted through a lifting cylinder; and when a to-be-tested engine cylinder head is conveyed to the blocking plate at the locking cylinder under the action of the conveying rollers, the requirements of sealing and air intake can be met through an air inlet and a plug on the blocking plate, locking of the engine cylinder head can be realized through a compressing plate on an installation frame, and air tightness detection of the engine cylinder head is realized through air-entrapping of an air pump.

Description

technical field [0001] The invention relates to the technical field of engine cylinder head detection, and more specifically, to an engine cylinder head airtightness detection device and a detection method thereof. Background technique [0002] The good airtightness of the engine is the premise of excellent car power. The engine cylinder head is the same as the cylinder block, which is the main part of the engine. Therefore, the airtightness test of the cylinder head is an important link in the automobile production process. Its significance mainly reflects Make a quantitative judgment as early as possible on whether the cylinder head can maintain good sealing during use, and avoid further processing and assembly of leaked workpieces, so as to ensure the overall quality and safety of the car during use. [0003] Traditional detection methods mostly rely on manual work, and the reliability of detection results largely depends on the technical level of the detection personnel,...
