The invention discloses a tool for machining a large-scale rotating member on a horizontal lathe. The tool comprises a big tool disk, steel plates and adjusting bolts. The 6-8 steel plates are uniformly welded to the same circumference of the back side of the big tool disk. Each steel plate is provided with a threaded hole. The adjusting bolts are outwards screwed into the threaded holes of the steel plates from the circle center. The invention further discloses a machining process for machining the large-scale rotating member on the horizontal lathe. The machining process comprises the stepsof assembling the tool; placing a workpiece on a workbench; mounting the tool; welding a cross brace in an inner pore of the flange end of the workpiece; placing the workpiece on a working platform ofa boring machine; rotating the working platform of the boring machine by 180 degrees; fixing the workpiece, conducting correction, turning the external diameter, the inner end face of a flange and the outer cylindrical surface, and turning the conical surface of the non-flange end and grooves; turning over the workpiece, correcting the workpiece, turning the end face of the flange end and the outer cylindrical surface; discharging the workpiece; and conducting checking and putting the workpiece in storage. The tool provided by the invention is simple in structure, capable of being utilized repeatedly and reasonable in the process. The adopted machining lathe is common, and the machining cost is low.
Description
technical field [0001] The invention relates to a processing tool and a processing technology of a large rotary part, and relates to the technical field of mechanical processing. Background technique [0002] There are many large-scale rotary parts in the existing mechanical processing field. The length of the workpiece is large and the wall is relatively thin. For example, the wall thickness of the expansion joint on the screw conveyor is 30mm, the length is 3163mm, the outer diameter of the rotation is 960 (0 / -0.5), and the end face of the expansion joint is not flanged. There is a 16° conical surface with a roundness tolerance of 0.05mm. The processing method in the prior art is to weld a cross support at both ends of the inner diameter of the workpiece, drill a center hole at the center of the support, and turn the outer diameter of the horizontal lathe and the sides of the flange to the drawing. After the support is cut off according to the above method, The deformatio...
