Description

technical field [0001] The invention relates to the technical field of manufacturing automobile engine intake manifolds, in particular to a detection device for metal implants in engine intake manifolds made of plastic materials. Background technique [0002] The intake manifold is the most important part of the engine intake system. The intake system determines the intake efficiency of the engine and the uniformity of each cylinder, and has a great impact on the overall performance of the engine. The traditional intake manifold is a metal casting. At present, most intake manifolds are made of aluminum alloy. Due to the complex structure of the intake manifold, metal mold sand casting is generally used.

Problems solved by technology

The traditional intake manifold is a metal casting. At present, most intake manifolds are made of aluminum alloy. Due to the complex structure of the intake manifold, metal mold sand casting is generally used. The surface is rough, the inflation resistance is large, and the quality is large. In order to meet the requirements of reducing weight, reducing fuel consumption, improving engine performance and reducing emissions, some automobile manufacturers have begun to use nylon plastic intake manifolds. Plastic intake manifolds have the advantages of light weight, low production costs, small airflow resistance, and low noise. Advantages, however, because the strength of plastic is not as strong as metal, in order to ensure that the plastic intake manifold can work reliably, it is necessary to embed a metal sleeve on the connecting end of the plastic intake manifold and the engine intake, throttle and intake manifold fixing frame Tubes or nuts, usually 20-30 metal sleeves or nuts are embedded in a plastic intake manifold. Therefore, metal implants need to be tested during the production of plastic intake manifolds to avoid missing metal sleeves or nut

In the prior art, there is no detection device specially used for metal implants of plastic intake manifolds. During the detection, workers need to detect with the naked eye. Due to the large volume and irregular shape of the intake manifold, manual detection is time-consuming, laborious and labor-intensive. Missing inspections are prone to occur, and manual inspections cannot quickly determine whether the angle, depth, and relative positional relationship of metal implants meet the requirements, which affects the quality of the intake manifold
