Background technology
At present, domestic rail transportation system has carried out large-scale several times speed-raising, is being faced with many new problems again aspect the maintenance of rolling stock and the safe maintenance.Showing the most outstanding one is that the right requirement on machining accuracy of vehicle wheel is improved greatly, and railway locomotive, vehicle and EMUs are behind long-play, and wheel can produce wearing and tearing and distortion to the flange tread that contact with rail, need carry out turning and process resizing.The car wheel lathe that do not fall be railway locomotive depot, rolling stock section and motor-car utilization institute to the special equipment of wheel to turning, be used for locomotive, vehicle and EMUs wheel the turning that do not fall to taking turns of not disintegrating processed.
The complex structure of the numerically-controlled slide device of the existing car wheel lathe that do not fall is inconvenient to process, and needs manually to change cutter, and wheel is to axial current potential device spacing not accurate enough to axial motion.
The utility model content
To above-mentioned prior art, the technical problem that the utility model will solve provides a kind of numerical control easy to process, rational in infrastructure lathe that do not fall.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of numerical control car wheel lathe that do not fall, comprise support, lathe bed, rail set, two roller supporting device, outer axle box bracing or strutting arrangement, axle box hold-down devices, wheel to axial direction positioning device, cutter holder device, control operation device, lubricating arrangement, chip removal device, and said cutter holder device comprises carriage saddle, cutter; Wherein, Said carriage saddle is provided with vertical planker and cross slide, on vertical supporting plate, is provided with vertical gearbox and guide rail, and vertically gearbox is provided with servo longitudinal motor and vertical ball-screw; Cross slide is provided with checkout gear box and horizontal slide plate; Cutter is arranged in the folder cutter groove of horizontal slide plate, is connected with horizontal ball-screw, lateral velocity variation case under the cross slide, and the lateral velocity variation case is provided with horizontal servomotor.
Further, said take turns to axial direction positioning device mainly by base be located at left slide, anti-channeling oil cylinder, the right slide on the base, and be located at left anti-channeling wheel and right anti-channeling wheel formation on left slide and the right slide.
Further, said guide rail is the quenching steel guideway.
Further, said cutter is a throwaway tool.
Compared with prior art; The utlity model has following beneficial effect: cutter holder device drives the knife rest sliding panel through gearbox, servomotor and ball-screw and realizes that through NC cutting tool ball-screw is adopted in transmission to taking turns processing profiling automatically, and forward and reverse rotary gap is little during work; The characteristic that resistance is little; Can fully guarantee wheel to crudy and working (machining) efficiency, guide rail adopts the quenching steel guideway, and anti-wear performance is good, intensity is high, long service life.Wheel stretches out promotion slide block drive anti-channeling wheel to axial direction positioning device through oil cylinder and is pressed on the wheel rim medial surface, prevents that wheel is to axial float.
