The utility model discloses a device has that centering is fast, the precision is high, simple structure and characteristics such as with low costs, need not to press from both sides tight during the wheel wheel measuring, and easy operation can obtain the tread parameter of the even sampling of wheel round, has satisfied tire tread parameter on -line measuring's precision and beat requirement among the automated production, has better using value.
Description
Technical field
The utility model relates to train wheel geometric parameter on-line checkingi centring means, especially a kind of taper pin dithering type Self-centering device of wheel tread parameter detecting.
Background technology
Wheel is one of most important composition in rail vehicles running part.Rolling stock is in operation, and wheel contacts with rail and produces and relatively rolls, and wheel tread geometric parameter is very large on the security of rolling stock, running stability and riding comfort impact.Therefore, the detection of wheel tread geometric parameter is one very important operation in wheel production run, is intended to guarantee that the tread geometric parameter of the wheel produced is in the error range of regulation.
At present, during wheel is produced, tread geometric parameter mainly or by artificial model relative method detects.Because manual detection can not meet the requirement of wheel automated production beat far away, therefore, sampling observation mode is adopted to carry out.By artificial model relative method sampling observation, the shortcoming such as have that detection and location are inaccurate, error is large, poor reliability, loss are high, labour intensity is large and efficiency is low, and model comparative measurement method can not get the quantitative data of tread, the inquiry of wheel tread data is not realized by computer technology, statistical study can not be carried out to the mismachining tolerance of production line, therefore, artificial model relative method sampling observation, can not meet the needs that wheel tread parameter detecting precision in wheel automated production, beat and wheel tread data Life cycle are reviewed.
Summary of the invention
The purpose of this utility model is just to provide that a kind of centering is fast, precision is high, structure is simple, cost is low, can meet the taper pin dithering type Self-centering device of the wheel tread parameter detecting of accuracy of detection and beat requirement in automated production.
The taper pin dithering type Self-centering device of wheel tread parameter detecting of the present utility model, comprise friction step disk, gear rotating disc, flutter hydraulic cylinder, thrust ball bearing, protection seat, support tray, synchronous hydraulic cylinder, base, it is characterized in that, friction step disk upper surface and hub for vehicle wheel end contact are used for supporting wheel, hub for vehicle wheel Hole chamfering is close to by the conical surface of T-shaped taper pin, its external cylindrical surface is contained in the endoporus of positioning disk, spring is contained between T-shaped taper pin endoporus and positioning disk endoporus, the external cylindrical surface of positioning disk is arranged in the endoporus of friction step disk, friction step disk lower surface and gear rotating disc are joined together by screw, gear rotating disc is supported by thrust ball bearing, thrust ball bearing is supported by support tray, the bottom of support tray connects with the piston rod of synchronous hydraulic cylinder, synchronous hydraulic cylinder is arranged on base, flutter hydraulic cylinder is arranged on support tray center bottom, the piston rod of flutter hydraulic cylinder contacts with the bottom surface of positioning disk through gear rotating disc axially extending bore.
The taper pin dithering type Self-centering device principle of work of wheel tread parameter detecting of the present utility model is, after wheel sends into this detection station by rollgang, synchronous hydraulic cylinder rises, wheel departs from rollgang, meanwhile, under the effect of T-shaped taper pin, spring and friction step disk, T-shaped taper pin automatic height adjustment, contact with hub for vehicle wheel Hole chamfering, complete the coarse positioning of wheel detection; By the piston rod of flutter hydraulic cylinder, promote positioning disk Compress Spring and touch T-shaped taper pin, the zitterbewegung of flutter hydraulic cylinder is passed to wheel, making wheel automatically adapt to the centering of T-shaped taper pin, contact well with friction step disk again, complete accurate location.Driven wheel rotating disc makes it rotate, and by the moment of friction that wheel weight is formed on friction step disk, can drive vehicle wheel rotation, complete the uniform sampling within the scope of wheel tread data 360 °; Synchronous hydraulic cylinder declines, and wheel is put back into rollgang, sends detection station, measures station ready, accepts another wheel and enter measurement.
The taper pin dithering type Self-centering device of wheel tread parameter detecting of the present utility model, the shortcoming such as overcome that the sampling observation of artificial model relative method has that detection and location are inaccurate, error is large, poor reliability, loss are high, labour intensity is large and efficiency is low, it has that centering is fast, precision is high, structure is simple and the feature such as cost is low, without the need to clamping when rotation of wheel is measured, simple to operate, the tread parameter that wheel one encloses uniform sampling can be obtained, meet precision and the beat requirement of wheel tread parameter on-line checkingi in automated production, have good using value.
