AI Technical Summary

Technical Problem

In the prior art, when detecting the sealing properties of hydraulic cylinders, the sealing properties at the connection between the hydraulic rod and the hydraulic cylinder cannot be effectively determined, resulting in inaccurate detection results.

Method used

A sealing test equipment based on hydraulic rods is designed, using airtight detection components. By setting up an upper annular airbag and a lower annular airbag, the pressing of the movable block and the pressing ring is used to close the gap between the airbag, and adjust the pressing pressure by adjusting the rotary knob to ensure tight contact with the surface of the hydraulic rod to be tested.

Benefits of technology

The airtightness detection of the connection between the hydraulic cylinder and the hydraulic rod is realized, and the material and smoothness of the cylinder block and the hydraulic rod are adjusted to ensure the accuracy and reliability of the detection results.

Abstract

The invention discloses sealing performance testing equipment based on a hydraulic rod, particularly relates to the sealing performance testing equipment based on the hydraulic rod, and aims to solve the problems that due to different diameters, materials and smoothness of a cylinder body and the hydraulic rod, the air tightness of a device is not tight, the contact between the device and the hydraulic rod is not tight, air leakage is caused, and the detection effect is influenced. According to the scheme, the device comprises a box body, a cutting groove is formed in the inner wall of the bottom of the box body, a bearing platform is arranged in the cutting groove, a hydraulic cylinder is arranged in the box body, a round hole is formed in the outer portion of the hydraulic cylinder, and an oil inlet and outlet is connected into the round hole through bolts. According to the leakproofness test equipment based on the hydraulic rod, when the leakproofness detection assembly is used for detecting the leakproofness of the joint of the cylinder body and the hydraulic rod, adjustment can be carried out according to different materials and smoothness of the cylinder body and the hydraulic rod, tight contact with the surface of the hydraulic rod to be detected is ensured, the leakproofness of the device is ensured, and the reliability of the device is improved. And the detection result is accurate and reliable.
