Embodiment Construction

[0030] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0031] Such as figure 1 , 2 As shown, it is a schematic diagram of the structure of the cylinder cover assembly to be tested. The cylinder cover assembly is divided into three compartments. type area, leaving two areas on both sides of the middle, which are defined as the first compartment area 3 and the second compartment area 2, respectively. There is a flat opening 4 on the cover shell at one end in the I-shaped area, and the port of the opening is a flat port, and there are two openings on the cover shell at the other end in the I-shaped area , the ports of the two non-flat openings 5 ​​are non-flat ports. The side shell of the first compartment area is provided with a side opening 6 with a flat port, and the shell ...

Abstract

The invention provides a test equipment for a vehicle cylinder cover cap assembly, belongs to the detection technology field and solves a problem that airtightness of cylinder cover cap assemblies in the prior art is not easy to detect. According to the test equipment for the vehicle cylinder cover cap assembly, an edge of a work table is provided with multiple cylinders, pistons of the cylinders are provided with clamping rods used for compacting the edge of the cylinder cover cap assembly onto the work table, the work table is provided with an air inlet, holes of a corresponding cylinder cover cap assembly casing are provided with core plugs, the core plugs are controlled through a telescoping mechanism, the core plugs comprise a flush end core plug and an external expansion core plug, the external expansion core plug comprises an inner rod body, one end of the inner rod body is provided with a baffle body, the inner rod body is sleeved in an elastic ring, and the inner rod body is sleeved in an outer sleeve. The test equipment has a simple structure, realizes low cost, adapts to holes of end faces having different sealing degrees and can realize detection on different separation areas of a cover cap.

Description

technical field [0001] The invention belongs to the technical field of testing, and relates to an air tightness testing device, in particular to testing equipment for a vehicle cylinder cover assembly. Background technique [0002] The cylinder cover assembly is the cylinder head of the automobile engine. Its function is that the cylinder cover is a cover on the steel body of the engine, which prevents external impurities from entering the engine, prevents internal oil leakage, oil mist separation, and crankcase pressure regulation. , to isolate the structure from transmitting noise, and to serve as the mounting support for other components. The cylinder head is subjected to the mechanical load caused by the gas forces and tightening of the cylinder bolts, and is also subjected to high thermal loads. Therefore, the cylinder cover must have good airtightness, and the airtightness test must be carried out before the cylinder cover leaves the factory. However, the cylinder he...
