Problems solved by technology
However, there are certain problems in the above method. One is that the piston rod thrust of the lifting hydraulic cylinder is relatively large, so when the lifting hydraulic cylinder pushes the pressing block to contact the surface of the cylinder head, it is easy to cause damage to the surface of the cylinder head; When it is tight, it is usually necessary to position the cylinder head to position the cylinder head, so that the air pipe can pass air into the cylinder head, so the positioning cylinder needs to sink into the water with the cylinder head, which has a great impact on the quality and life of the positioning cylinder; at the same time After the cylinder head is tested, the moisture on the cylinder head will remain on the cylinder head, which will easily cause the corrosion of the cylinder head

The invention discloses a dual-power system cylinder cover sealing test machine which comprises a test box, a bearing plate used for placing a cylinder cover is arranged above the test box, test mechanisms used for testing the airtightness of the cylinder cover are symmetrically arranged on the two sides in the bearing plate, the bearing plate is arranged below a pressing mechanism, the test box is arranged in a fixing frame, and the fixing frame is arranged on the test box. A lifting hydraulic cylinder used for driving the pressing mechanism to ascend and descend is arranged on the fixing frame, and a taking and placing mechanism used for taking and placing the cylinder cover is arranged on one side of the testing box. The pressing mechanism is arranged, and the pressing hydraulic cylinder on the pressing mechanism is matched with the pressing air cylinder, so that when the pressing plate makes contact with the surface of the cylinder cover, the pressing air cylinder with small thrust continues to press the two ends of the cylinder cover, the sealing performance of the cylinder cover is guaranteed, and meanwhile damage to the surface of the cylinder cover due to the fact that the thrust of the pressing hydraulic cylinder is too large is avoided.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a double power system cylinder head sealing test machine. Background technique [0002] The cylinder head of the automobile engine is a very important component in the engine system. It is mainly used to close the upper part of the cylinder, form the combustion chamber, and serve as the support for the camshaft, rocker shaft and intake and exhaust pipes. The air tightness of the cylinder head is one of the important factors affecting product quality. [0003] At present, various enterprises mainly use the water inspection method for the tightness detection of the cylinder head, that is, firstly clamp and block the cylinder head with a clamp, and then use the lifting hydraulic cylinder to compress the cylinder head and sink the cylinder head into the water, and pass the air pipe to the cylinder head. Compressed air is introduced into the inner cavity for testing. However, the...
