Description
Technical field
The present invention relates to the technical field of numerically controlled lathe, specifically, the inside and outside axle box axial location relating to a kind of car wheel lathe that do not fall fixes the method for the centre of gyration, pass through coordinate based on lathe, to take turns wheel rim top as benchmark, by inside and outside axle box axial location wheel to axle center, thus fast pulley is to the method for a kind of do not fall car wheel lathe processing motor-car, the Railway wheelset of the centre of gyration.
Background technology
China Railway system has entered raising speed by a large scale several times, and high-speed railway operation accounting significantly expands, and operation mileage is sure to occupy the first in the world.Because the Development of High Speed Railway time is short, speed is fast, general fast train, subway train utilization amount are huge, backwardness is relatively equipped in maintenance, therefore the transportation safety of bullet train, EMUs, locomotive, passenger-cargo carriage vehicle, subway train, urban light rail train faces many new problems, wherein bullet train wheel is to the geometric accuracy of processing, the degree of operating steadily such as direct relation bullet train riding quality and ride quality.Particularly geometric accuracy is underproof takes turns operation, the life security of the serious threat people and national wealth safety, through investigation, there is a lot of axle box end cap in the bullet train CRH3C type of current operation, CRH380B type EMUs, ground connection lid construction bolt gets loose fault, through investigation and analysis, wheel there are obvious 18 ~ 20 rank polygons and circuit individual segments exist ripple mill wavelength close with wheel polygon, during EMUs high-speed cruising, produce close with wheel polygon Forced Frequency of circuit Forced Frequency is resonated, and the vibration of aggravation axle head is the basic reason causing bolt to get loose.But produce EMUs wheels and there is the polygonal reason in obvious rank and the existing motor-car floating rotary center that car wheel lathe takes turns adding man-hour that do not fall and there is positive connection.
The existing motor-car car wheel lathe that do not fall all takes wheel tread and external centring, it is all centering standard with tread, due to wheel tread all experience wear, take turns left and right wheels two tread existence wheel footpath dimensional discrepancy itself, differ in size problem, or there is the irregular phenomenons such as wheel tread ellipse, polygon, be difficult to the pivot accurately finding wheel right, cause its processing to there will be all multiple errors.The more important thing is that the friction driving roller that the car wheel lathe support wheel that do not fall at present is right and wheel carrier structure must adopt servo-actuated or float design, in wheel is to process, friction driving roller and wheel tread contact surface are one and change along with working angles, cause Railway wheelset and friction driving roller to be in servo-actuated or quick condition.Above-mentioned design is fixing or floating during processing work must be caused to turn round, and causes and be there is by wheel tread phenomenons such as losing circle, bring all multi-risk Systems and unsafe factor to railway operation, brings potential safety hazard particularly to bullet train and motor train unit train.Therefore, it is unscientific that the car wheel lathe that do not fall processing wheel is felt relieved to foreign round to roller.Adopt a kind of method of the car wheel lathe processing Railway wheelset fixation workpiece centre of gyration that do not fall of more science, improve wheel to machining accuracy, to adapt to China Express Railway demand for development, particularly guarantee the security of operation of China's motor train unit train, bullet train, reduce people's life's property loss.
Summary of the invention
A kind of inside and outside axle box axial location of the car wheel lathe that do not fall is the object of the present invention is to provide to fix the method for the centre of gyration, pass through coordinate based on lathe, to take turns wheel rim top as benchmark, by inside and outside axle box axial location wheel to axle center, thus fast pulley is to the method for a kind of do not fall car wheel lathe processing motor-car, the Railway wheelset of the centre of gyration.Not fall the fixing of the right centre of gyration of car wheel lathe processing wheel to reach single shaft or twin shaft, improve wheel to machining accuracy, the object improving train operating safety and riding quality.Solve the existing car wheel lathe that do not fall do not fix at the wheel that do not disintegrate taking turns gyroaxis axle center in right process with band axle box or float, cause processed wheel to there is to wheel tread the problem losing circle.The present invention is adopted to be that the single shaft of design principle manufacture or twin shaft do not fall car wheel lathe for the right wheel processing that do not fall of high speed motor car, railroad train, urban light rail train and subway train wheel, achieve lathe automation processing, improve wheel to machining accuracy, ensure train operation smoothness.
For realizing the object of the invention, the technical scheme adopted is: a kind of inside and outside axle box axial location of the car wheel lathe that do not fall fixes the method for the centre of gyration, pass through coordinate based on lathe, to take turns wheel rim top as benchmark, by inside and outside axle box longitudinal balance bracing or strutting arrangement locating wheel to axle center, thus fast pulley is to the centre of gyration, it is characterized in that, adopt inside and outside axle box longitudinal balance bracing or strutting arrangement, axle box hold-down devices, control system, lathe automatic detection device, drive unit is to form the car wheel lathe processing motor-car that do not fall, the centre of gyration of Railway wheelset, the method that inside and outside the described car wheel lathe that do not fall, axle box axial location fixes the centre of gyration comprises the following steps:
