Automatic detection equipment for air tightness of engine cylinder cover

Abstract

The invention provides automatic detection equipment for the air tightness of an engine cylinder cover. The automatic detection equipment comprises a machine body, an air tightness detection device fixedly connected to the machine body, a detection platform fixedly connected to the machine body, multiple pressing cylinders which are arranged above the detection platform and are matched with the detection platform to close the engine cylinder cover to be detected to form a closed cavity, and a sealing clamp which is arranged on the detection platform and is used for simulating an air valve to seal the engine cylinder cover to be detected, so as to detect the quality of a fitting surface of the engine cylinder cover to be detected, wherein the air tightness detection device is connected withthe closed cavity through a pipeline. According to the automatic detection equipment for the air tightness of the engine cylinder cover, the quality of the fitting surface of the engine cylinder cover to be detected is detected, and the detection operation is quick and convenient; the machining quality of the air valve fitting surface of the engine cylinder cover can be measured effectively, visually and really; and the automatic detection equipment is favorable for realizing real-time monitoring of the quality and improvement of the quality on a machining production line.

Description

technical field [0001] The invention relates to the technical field of airtightness detection, in particular to an automatic detection device for airtightness of an engine cylinder head. Background technique [0002] In related technologies, it is generally judged indirectly whether the quality of the engine cylinder head is qualified and whether there may be leakage by monitoring the machining accuracy of the conical surface of the engine cylinder head seat, such as roundness, runout, and angle. figure 1 As shown, or in the assembly line, after assembling the upper valve, to detect the airtight leakage problem, there are the following technical defects: [0003] (1) It is impossible to effectively, truly and intuitively detect the amount of airtight leakage after the engine cylinder head and the valve are matched. [0004] (2) The airtight leakage of the engine cylinder head valve cannot be effectively monitored on the processing line. It can only be detected on the assemb...

Problems solved by technology

[0003] (1) It cannot effectively, truly and intuitively detect the airtight leakage after the engine cylinder head and valve are matched

[0004] (2) The airtight leakage of the engine cylinder head valve cannot be effectively monitored on the processing line. It can only be detected on the assembly line, resulting in a long cycle, easy quality control, and a high rate of defective airtight leakage after assembly.
