Abstract

The invention belongs to the technical field of detection equipment, and specifically discloses a hydraulic cylinder detection device. The device includes a machine frame, an air inlet unit, a detection unit and a limit part. The air inlet unit includes a first driving part and a piston barrel, and the detection unit includes a second driving part, a gas collecting part and a detection part. The gas collecting part includes a T-shaped tube, an elastic air bag and a second pipeline, and the detection part includes a detection tube and a detection tank. The detection tank is filled with water, the detection tube is communicated with a vertical tube, and the air outlet end of the detection tube stretches into the detection tank. The detection device with the above structure can solve the problem that the air tightness detection of a hydraulic cylinder is not accurate enough in the prior art.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, in particular to a hydraulic cylinder detection device. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has the characteristics of simple structure and reliable operation. When the hydraulic cylinder is used to realize the reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The most common problem of hydraulic cylinders is oil leakage, so the hydraulic cylinders produced must be tested for sealing performance. The main object of testing is the sealing performance between the hydraulic cylinder and the piston. qualified. [0003] The Chinese patent with the notification number CN106840555B discloses a hydraulic cylinder airtig...
