Device for detecting tightness of two junction surfaces between oil inlet/outlet valve and pump cover and plunger sleeve

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.
