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.

Example Embodiment

[0017] Such as Figure 2~3 The sealing test equipment of the joint surface of the oil inlet and outlet valve, the pump cover and the plunger sleeve shown includes: a frame, a bed, a pneumatic and a detection control system, and is characterized in that it also includes a fixture, two-station automatic feeding pneumatic Sliding table, flexible blocking detection device, shutdown safety protection device, automatic feeding device, all devices are installed on the frame and bed; the two-station automatic feeding pneumatic sliding table consists of three cylinders 1, guide rods 2, and The guide sleeve 3 and the sliding bracket 4 are composed. The flexible plugging detection device is composed of a plugging head upper body 5, a plugging head lower body 6, and a flexible guide shaft 7. The shutdown safety protection device is composed of a pin shaft 8, a bracket 9, and a pin confirmation device 10. The automatic feeding device is composed of a cylinder 11, a bracket 12, a guide rod 13, a guide sleeve 14, a stopper 15 and a manipulator 16. The clamp is composed of a clamping body 17, a positioning block 18, a positioning pin 19 and an error prevention device 20.
[0018] Manually combine the pump cover and the oil inlet and outlet valve components and place them on the positioning surface of the fixture, manually insert the pins to confirm, and then put the plunger sleeves into the two manipulators 16 respectively, and press the two-hand start button. The two automatic feeding devices 700 are started at the same time, and the automatic feeding is 70mm. The two-station automatic feeding pneumatic sliding table 400 is lowered by 50mm for the first time. The flexible guide shaft 7 in the flexible blocking detection device 500 is inserted into the center hole of the plunger sleeve. . The two automatic feeding devices 700 are reset at the same time, and the plunger sleeve falls to the surface of the oil inlet and outlet valves. The two-station automatic feed pneumatic sliding table 400 is lowered 44mm again to block and seal the workpiece. The detection gas source is respectively introduced into the enclosed room I and II room with a clean detection gas of 0.4Mpa, and the sealing degree detection of the two joint surfaces is started. After the inspection is completed, the two-station automatic pneumatic sliding table 400 is reset, and the flexible guide shaft 7 prevents the plunger sleeve from being lifted up by the blocking surface, and the inspected workpiece is finally offline manually.
