The invention relates to a visual inspection system for the surface quality of an air spring, comprising: a base body; a horizontal driving part, which is installed on the base body; a horizontal sliding component, which is installed on the base body and is connected with the horizontal driving part; The vertical sliding component is installed on the horizontal sliding component and is connected with the vertical driving component; the rotating driving component is installed on the vertical sliding component; the rotating component is rotatably connected with the rotating driving component; the vision unit is installed on the rotating component; The measuring device is installed on the rotating part and is located on the side of the vision unit, used to measure the size of the air spring and detect the torsional offset of the air spring capsule; the control device, including the horizontal driving part, the vertical driving part, the rotating A controller to which the unit and the measuring device are electrically connected. The invention has a simple and reasonable structure, is easy to operate and maintain, can realize automatic detection of the surface quality of the air spring, has high detection efficiency and detection accuracy, and is safe and reliable.
Description
technical field [0001] The invention belongs to the technical field of rail transit, relates to air spring quality detection technology, in particular to a visual detection system for air spring surface quality. Background technique [0002] Air springs are key components of rail vehicle vibration reduction systems. At present, the domestic air spring surface quality inspection mainly relies on manual inspection. The specific method is as follows: the operator uses a hand-held flashlight to perform the air spring surface inspection and size measurement. The inspection accuracy and coverage are low, and the inspection efficiency is low. At the same time, since the detection process needs to be carried out in the inflated state of the air spring, there is a potential safety hazard. SUMMARY OF THE INVENTION [0003] Aiming at the above problems such as low detection efficiency existing in the prior art, the present invention provides a visual detection system for the surface...
