Test table for airtightness of crank case

Abstract

The invention discloses a test table for airtightness of a crank case. The test table comprises a first placing groove, a hinge, a hydraulic rod, a first hydraulic rod, a second hydraulic rod, a spring, a rubber end part, an air inlet pipe, a pressure meter, a detection indicating lamp liquid crystal screen, an operation panel, a second placing groove, a first case, a fixed knob, a handle, a stopknob, a power supply connector, a fixed rod, a telescopic support leg, a telescopic rod, a hole, a regulating knob, a second case, a pressure regulating valve, organic glass, an airtightness detectioncase and an LED bulb. The test table has the beneficial effects that an clamp can be automatically regulated according to the size of an article to be detected in the airtightness test by a user; thearticle to be subjected to detection test can be fixed; meanwhile, the spring is arranged on the hydraulic rod, so that the damage to the article is enabled to be avoided during the article fixation;meanwhile, an observation window and the existing single-side observation are changed into two-side observation; the view angle is wider; the inspection is more careful; the problems can be fast discovered.

Description

technical field [0001] The invention relates to a test bench device, in particular to a crankcase air tightness test bench, which belongs to the technical field of industrial testing. Background technique [0002] The air tightness test bench is suitable for high-pressure air tightness test of small valves, pipelines, downhole tools and other products, safety valve performance test and correction, high-pressure gas cylinder filling and other professional production and manufacturing test benches. [0003] At present, the ordinary airtightness test bench commonly used in the work has a single-sided small window for observation, and the observation angle is very small, which cannot meet the required observation strength on some items, and the fixed airtightness test box in the ordinary type The device is rigid and cannot flexibly fix different items in all directions. Even some fixing clips with simple knowledge of the fixing device will damage the detected items when they pla...

Problems solved by technology

[0003] At present, the ordinary airtightness test bench commonly used in the work has a single-sided small window for observation, and the observation angle is very small, which cannot meet the required observation strength on some items, and the fixed airtightness test box in the ordinary type The device is rigid and cannot flexibly fix different items in an all-round way. Even some fixing clips with simple knowledge of the fixing device will damage the detected items when they play the role of fixing.
