Problems solved by technology

[0003] However, after practice, it is found that the above methods have shortcomings: the above methods are all open-loop control systems, and the positioning accuracy is not reliable
And after the probe carrier is close to the wheel tread, a rigid bonding method is adopted, resulting in uneven bonding strength and difficult control of bonding pressure

Abstract

The invention discloses a carrier positioning method based on sensor technology and a positioned. Compared with a conventional automatic probe carrier positioner, the positioner is characterized in that a probe carrier (flexible) automatically attaches to a tire tread, through sensors symmetrically installed on the two sides of a probe carrier and a high-precision servo rotary mechanism, and has the advantages that a wider wheel diameter application scope is ensured, and attaching pressure of the probe carrier is uniform and adjustable. A servo system is employed, automation level is higher, and the positioner can replace a manual positioning probe carrier to conduct wheel flaw detection work. Efficiency for flaw detection of various wheels can be improved, and the economic benefit is high. A high-precision servo motor is ensured, the positioning precision is high, repeatability is high, and flaw detection accuracy is ensured. A multi-shaft servo motor is employed to realize adjustment of any probe attitude in a three-dimensional space. Compared with a conventional automatic probe carrier positioner, the positioner is more suitable for complex underbody spatial environment of trains of various models to conduct probe positioning.

Description

technical field [0001] The invention relates to the technical field of flaw detection of train wheels, in particular to a carrier positioning method and positioning device based on sensor technology. Background technique [0002] "Carrier positioning device" specifically refers to the device for positioning various detection probes to the corresponding detection positions of the above-mentioned wheel sets when performing flaw detection operations on the wheelsets of various types of trains currently running. The main applications of the current "carrier positioning device" are: manual placement of the probe carrier positioning device, automatic positioning devices such as the use of cylinder drive or ordinary motors with distance measuring sensors as the power source for probe carrier positioning. [0003] However, it has been found through practice that the above-mentioned methods have shortcomings: the above-mentioned methods are all open-loop control systems, and the posi...
