Embodiment:

In a kind of tilting gearing of steelmaking converter, a large-scale backing ring is arranged, gudgeon and backing ring are one, and ton is about 8 meters surplus in the of heavily about 50, and the backing ring diameter reaches more than 5 meters, and gudgeon need carry out cylindrical and keyway processing, and surface roughness requires to reach

, 4 step axialities of screech owl axle require to be controlled in the 0.04mm the long 1100mm of keyway, about deeply 72mm.Existing metal cutting equipment is all too heavy because of this workpiece, elevating capacity restriction in super lathe bed load and the factory building, and can't process, the utility model can address the above problem, and is described in further detail in conjunction with the accompanying drawings:

It is lead (11,22,40) that the utility model adopts three cylinders, and the two ends of three leads are fixedly connected into lathe bed with front support stand (13), rear support stand (4), and this lathe bed is fixed on the processed axle part through locating shaft (12,18).Being equipped with between three leads (11,22,40) can be around the cutter head casing (9) of the rotation of processed axle part, the bull gear (34) that cutter saddle (7) are housed and cutter head case body (32) formation.Its transmission process is by feed rod (14) driven gear (37), the knife rest (7) of cutting tool is housed around processed axle part rotation (present embodiment symmetry on bull gear is equipped with two knife rests) with bull gear (34) drive of gear (37) engagement.Two feed nuts (26,30) are housed on the cutter head case body, drive the axial feed motion of realizing the cutter head casing by two leading screws (27,5).The power of feed rod and leading screw is provided by two gearboxes (16,15) respectively.Flexible deformation for rigidity in the assurance process and adjustment lead also installs an adjustable intermediate support frame (6).

Cutter head case body (32) is installed in three leads (11,22,40) between, main fairlead (28) by four frees degree of restriction matches with three leads with the adjustable brasses (19) and half brasses (23) of circumferential two frees degree of restriction, adjustable brasses can be adjusted use level by the adjustment screw (21) that is fixed on the bearing (20) on the cutter head casing, takes as the leading factor to the cover fuel feeding lubricated by lubricating cup (29) during work.Copper bush (36), bull gear (34) are housed on the cutter head casing, and be located by door (35), door (33) is with its sealing, two knife rests that cutting tool is housed are installed on bull gear, be symmetrical distribution, there is a pinion (37) that is positioned on the casing by two bearings and end cap to mesh at lower box, will passes to bull gear by the active force that feed rod (14) transmits by the key (39) that is fixed on the pinion with bull gear.

Front support stand (13) is by claw (44) and support column (45), screw mandrel (47), end cap (48), and round nut (46) is fixed on the locating shaft (12), by adjusting screw mandrel (47) front support stand is adjusted, front support stand is by slips (41) and three fastening connections of lead, the supporting part that feed rod and two leading screws are arranged on front support stand, two leading screw diagonal angles are settled, one leading screw end is equipped with sprocket wheel (3), twin wheels (sprocket wheel is equipped with in another leading screw end, bottom, gear wheel) (51), its two sprocket wheels specification is identical, two sprocket wheels are meshed to realize Synchronous Transmission with the chain (2) of closure, distend wheel (49,50) is installed on the bracing frame body.The same substantially front support stand of rear support stand (4) body construction.

Intermediate support frame (6) adopts and divides body structure, after this part need treat that lead, back and front supporting frame and cutter head casing are in place, load onto more than half bearing support (57) and smaller part bearing support (56) more respectively, fixing with alignment pin (54) bolt (55), method of adjustment is ditto described.

Keyway carries out milling by the small-sized milling head (10) that is installed on the cutter head casing.If the axle part of being processed does not have endoporus, can reach the purpose of fixing above-mentioned bracing frame by the form that changes locating shaft.The utility model can be generalized in the cylindrical processing on various super larges, the profile shaft spare workpiece, some are unfavorable for transporting and the processing problems of the workpiece that lifting and existing equipment are not processed can to solve (large-scale steel plant, power station, power plant) in the large-scale construction project, the utility model is simple in structure, flexible, economical and practical, considerable benefit.
