Abstract

An air-tightness testing instrument for a motorcycle damper cylinder comprises air cylinders (1). A lower detecting board (3) is fixed on a workbench (2), lower plugs (4) are fixed on the lower detecting board (3), and barometers (5) are fixed on the workbench (2) and are communicated and connected with central holes of the lower plugs (4). An upper detecting board (6) is arranged on a linear sliding rail (7) in inserted and sleeved modes, the air cylinders (1) are fixed on the workbench (2), and piston rods of the air cylinders (1) and the upper detecting board (6) are fixed together. An air collecting pipe (8) is fixed on the upper detecting board (6), air inflation nozzles (9) are communicated and connected with the air collecting pipe (8), the air collecting pipe (8) is communicated and connected with an air pressure station, and each air inflation nozzle (9) faces one lower plug (4). According to the air-tightness testing instrument for the motorcycle damper cylinder, the motorcycle damper cylinder is not steeped into water to carry out air-tightness detection any more, detection accuracy is high, and the damper cylinder can be prevented from being damaged by water erosion.

Description

Technical field: [0001] The invention relates to the technical field of motorcycle shock absorber production, and more specifically relates to a motorcycle shock absorber airtightness testing device. Background technique: [0002] Existing motorcycle shock absorber manufacturers need to detect the airtightness of the shock absorber after the motorcycle shock absorber is drilled. Patent No. 201020627068.X discloses a motorcycle shock absorber air tightness tester, which inflates the shock absorber in water, and observes whether the shock absorber leaks with the naked eye. Its weak point is: 1, the damping cylinder is immersed in water, can increase production process, and the damping cylinder immersed in water is susceptible to water erosion. 2. Observing the airtightness with the naked eye, there will be omissions, which is not conducive to improving the quality of the product. Invention content: [0003] The object of the present invention is to aim at the deficiencies ...
