Automobile engine cylinder head with complex shape and device for detecting flaws and leakage of tightness of automobile engine cylinder head with complex shape

Abstract

The invention discloses an automobile engine cylinder head with a complex shape and a device for detecting flaws and leakage of tightness of the automobile engine cylinder head with the complex shape, belongs to the technical field of industrial part processing and detection, particularly relates to a technique for detecting defects and leakage of complex automobile engine cylinder heads. The invention is characterized in that: the automobile engine cylinder head is of a dustpan shape, and has complex shape of having three edge planes; the leakage detection device is a plugging device formed by covering a panel controlled by an air cylinder or an oil cylinder and sealing planes of different edges; the different plugging devices comprise a top plugging device, a side-inclined plane plugging device, a bottom plugging device, and an interlayer through hole plugging device. The device has the advantages that: the device can perform plugging, flaw and leakage detection on the similar dustpan-shaped open cylinder head, complete the plugging and flaw detection of the interlayer holes, can be used on the entire fully-automatic assembly line because of being equipped with an automatic in-place feeding and discharging device, achieves the aims of reliable detection and high efficiency, and is suitable to be used in production.

Description

technical field [0001] It belongs to the technical field of industrial parts and components processing and testing, and is precisely a leak detection and flaw detection technology for complex automobile engine cylinder heads. Background technique [0002] After the cylinder head of the automobile engine is die-cast, there is a leakage requirement. Therefore, after preliminary processing and molding of die castings, it is necessary to carry out pressure flaw detection and leak detection on the oil passages, air pipes and water pipes of the cylinder head. The traditional cylinder head is rectangular in shape, and its six sides are horizontal and vertical, which is very Easy to block. With the requirement of energy saving and consumption reduction, the new generation of automobile engine stands out, its shape is complicated, such as one of the six faces is a slope, and there is no metal support at the intersection of a certain plane and the slope, that is to say, the middle is...

Problems solved by technology

Therefore, after preliminary processing and molding of die castings, it is necessary to carry out pressure flaw detection and leak detection on the oil passages, air pipes and water pipes of the cylinder head. The traditional cylinder head is rectangular in shape, and its six sides are horizontal and vertical, which is very easy to block

With the requirement of energy saving and consumption reduction, the new generation of automobile engine stands out, its shape is complicated, such as one of the six faces is a slope, and there is no metal support at the intersection of a certain plane and the slope, that is to say, the middle is empty. However, it can only rely on the lines connected around the plane and the inclined surface as the sealing surface, and the traditional sealing method is difficult to work
