Abstract
Description
Technical Field
[0001] The utility model relates to the field of diesel engine parts inspection, in particular to a piston cooling nozzle component inspection device. Background Art
[0002] In the diesel engine structure, the top of the piston, the cylinder gasket and the bottom of the cylinder head form a combustion chamber. The fuel and air mixture is compressed, burned and exploded in the combustion chamber. The power generated by the explosion pushes the piston downward, and the crankshaft is driven to rotate through the connecting rod to output power to the outside. The high temperature generated by the combustion and explosion of the compressed gas in the combustion chamber is transmitted to the top of the piston. Long-term high temperature will affect the life of the aluminum alloy piston. In order to reduce the temperature of the piston during operation, a cooling oil channel is designed on the top of the piston. The purpose of cooling the piston is achieved by continuously injecting relatively low-temperature engine oil into the oil channel. The function of the cooling nozzle component is to draw engine oil with a certain pressure from the main oil channel of the diesel engine, and spray it into the oil inlet of the piston cooling oil channel to cool the piston. The installation position Figure 1 As shown. Since the piston makes high-speed reciprocating linear motion when working, the cooling nozzle component has no direct contact with the piston. The oil column generated through the cooling nozzle outlet is injected into the oil inlet of the piston cooling oil channel. Therefore, the angle and outlet position of the cooling nozzle determine whether the cooling oil can enter the piston cooling oil channel and the amount of oil entering the oil channel, affecting the cooling effect of the piston. The cooling nozzle component is a spatial component, which is difficult to measure with general measuring tools, resulting in inaccurate test results and a greater impact on subsequent installation. Summary of the invention
[0003] In order to solve the above problems, the utility model provides a piston cooling nozzle component inspection device, which can simply and conveniently complete the inspection of the nozzle component and improve the inspection accuracy.
[0004] The technical solution is as follows: a piston cooling nozzle component inspection device, characterized in that it includes a base, a bracket is arranged on the base, a through groove is opened on the front of the bracket, one side of the through groove is provided with a contoured groove matching with the end of the cooling nozzle component, and the other side of the side wall is provided with a through hole, a detachable detection pin is arranged in the through hole, a matching slide groove is opened in the middle of the base and the bracket, a slider is arranged in the slide groove, and a positioning piece matching with the cooling nozzle component is arranged on the slider.
[0005] Its further feature is that a waist-shaped hole is provided on the sliding block, and a limiting screw passing through the waist-shaped hole is provided on the base.
[0006] After adopting the utility model, the nozzle component is mounted on the slider and positioned, and then the slider is moved to make the nozzle component snap into the through groove. If one end can be snapped into the profiling groove, it means that the length and angle of the oil pipe on one side meet the requirements. Then the slider is moved to align the oil outlet at the other end with the through hole. If the detection pin can be inserted from the through hole and the end is inserted into the oil outlet at the other end of the nozzle component, it is a qualified product. Otherwise, it is unqualified. After the nozzle component is rotated 180° and positioned, the other half can be tested. The operation is simple and convenient. The positioning piece and the profiling groove are used to ensure accurate positioning of the product, thereby improving the final detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
