Abstract

The invention discloses a device for detecting tightness of two junction surfaces between an oil inlet / outlet valve and a pump cover and a plunger sleeve, which is suitable for detecting the tightness of the two junction surfaces between the oil inlet / outlet valve and the pump cover and the plunger sleeve in batch production and manufacture of engines. The device comprises a frame, a lathe bed and a pneumatic control system. The device is characterized in that: the frame and the lathe bed are provided with a two-station automatic feeding pneumatic sliding table, a flexible plugging detection device, a shut-down safety protecting device, an automatic feeding device and a clamp, wherein the two-station automatic feeding pneumatic sliding table consists of a three-station cylinder, a guide rod, a guide sleeve and a sliding bracket. The flexible plugging detection device consists of a plugging head upper body, a plugging head lower body and a flexible guide shaft. The shut-down safety protecting device consists of a pin shaft, a bracket and a bolt determination device. The automatic feeding device consists of a cylinder, a bracket, a guide rod, a guide sleeve, a stop iron and a manipulator. The clamp consists of a clamp body, a positioning block, a positioning pin and an error-proof device. The device has the advantages of reasonable structure, high production efficiency, low labor intensity and high automation degree.

Description

technical field [0001] The invention is a device for semi-automatically detecting the sealing degree of two joint surfaces of an oil inlet and outlet valve, a pump cover and a plunger sleeve, which is used for batch assembly of fuel injection pumps in a high-pressure common rail system to ensure that there is no leakage between the two joint surfaces. Background technique [0002] At present, many manufacturers use manual detection methods to detect the sealing degree of the joint surfaces of the oil pump inlet and outlet valves of the high-pressure common rail system, the pump cover and the plunger sleeve. This method is labor-intensive, low in production efficiency, and the detection results are subject to human factors. Greater impact. In order to reduce labor intensity, increase production efficiency and improve product quality, it is imperative to further improve the detection method of the sealing degree of the two joint surfaces, so as to improve the automation of the...
