The object of the present invention is achieved like this: a kind of locomotive hollow shaft internal taper hole process equipment, comprise two ends be provided with the hollow endoporus main spindle box of centering chuck, size sled mechanism, can horizontal and vertical feeding movement guider, boring cutter seat, lengthen boring bar and boring cutter body, it is characterized in that described guider is installed on the opposite side relative to size sled mechanism in machine base, described main spindle box is between guider and size sled mechanism, the hollow endoporus of main spindle box is provided with hollow shaft positioning sleeve, and hydraulic lifting supporting is housed in the middle part of lathe.
A kind of locomotive hollow shaft internal taper hole processing method, is characterized in that taking the following step:
A. guider falls back on the longitudinal rear of lathe, to sling hollow shaft with suspender, the small end of hollow shaft is front, first one end locating surface B of hollow shaft is placed in the hollow shaft positioning sleeve of hollow endoporus main spindle box, laterally steadily advance, until locating surface A is placed to the correct position in hollow shaft positioning sleeve, the centering chuck at adjustment hollow endoporus main spindle box two ends, make hollow shaft center consistent with the centre of gyration of hollow endoporus main spindle box, clamping hollow shaft;
B. guider is made to get back to the position consistent with the hollow endoporus main spindle box centre of gyration, rise hydraulic lifting supports, carry the lengthening boring bar that boring cutter body is housed, big slide plate traverse feed promotes to lengthen boring bar through hollow shaft endoporus, lengthens boring bar termination and enters the bushing in guider and locate;
C. hydraulic lifting supporting is fallen, boring-and-turning mill main shaft, controls numerical control transverse feed mechanism and the numerical control longitudinal feed mechanism of guider and boring cutter seat, makes both work synchronous, by the difference of numerical control transverse feed mechanism and numerical control longitudinal feed mechanism cover to, complete the processing of hollow shaft internal taper hole;
D. hydraulic lifting supporting is risen, and mobile big slide plate exits lengthening boring bar, and guider is stepped back, and unclamps the centering chuck at hollow endoporus main spindle box two ends, hollow shaft is released and hangs away.
The solution of the present invention, have support owing to lengthening boring bar work in-process two ends, in processing, boring bar rigidity does not produce vibration very well, after processing, internal taper hole roughness can lower than 3.2, processing taper hole taper error is little, and can ensure the uniform wall thickness of hollow shaft, production efficiency improves five times.
