Abstract
The invention relates to a method and a device for machining a 180-degree shaft hole of a large rotating workpiece. The method comprises the following steps of: mounting a power head device on a gear hobbing machine clamping bracket through a quartering hole; mounting a plurality of equal-altitude sizing blocks with the height error less than 0.5mm on a cutter head; mounting a workpiece on the equal-altitude sizing blocks, rounding according to an inner hole of the workpiece, leveling according to a reference end face, and rounding one trunnion hole according to an initial marking line of a platform; machining the diameter and end face of the trunnion hole at one end by using a boring bar, rotating the boring bar by utilizing drive of an independent motor of the power head device, realizing feeding by utilizing back-and-forth movement of a machine tool body, and withdrawing the machine tool body into an initial state after the machining is finished; and performing precision indexing through a precision dividing function of the gear hobbing machine body, rotating the cutter head by 180 degrees, and machining a trunnion hole at the other end. The method has the advantages that due to the test, the position precision of the two holes through the method can be within 0.1mm, and high-precision manufacturing of the shaft holes at two ends of the large workpiece is realized.
Description
Technical field
The present invention relates to field of machining, relate in particular to a kind of method and device of machining large rotary work piece 180 degree axis holes.
Background technology
180 degree axis holes of large revolving body workpiece are difficult to processing, fill with the gudgeon hole such as the outlet slag.Because its tactical diameter is large, the two ends earhole is on center line, and distance center circle two ends are far away, can't the processing technology benchmark.So can't guarantee the axiality requirement in two holes.Common processing method can only rely on line, machines according to line with large-scale floor type boring machine again.But the line error is very large, usually can't satisfy the workpiece that position degree is had relatively high expectations.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this invention is to provide a kind of method and device of machining large rotary work piece 180 degree axis holes, realize the precision manufacturing of two ends axis hole.

2) with the equal-height padding iron of some height errors less than 0. 5mm, be installed on the cutterhead;
3) workpiece is placed on the equal-height padding iron, is just looking for circle by the endoporus of workpiece, just press the datum end face levelling, by platform initially rule look for one of them gudgeon hole circle just;
4) process diameter and the end face in an end gudgeon hole with boring bar, utilize the separate electrical motor of power head device to drive and realize the boring bar rotation, utilize lathe bed in the realization feeding that seesaws of guide rail, bed piece is withdrawn into original state after the completion of processing;
5) carry out accurate calibration, cutterhead Rotate 180 degree, repeating step 4 by the accurately minute tooth function of gear-hobbing machine lathe itself);
The device of described machining large rotary work piece 180 degree axis holes comprises gear-hobbing machine, equal-height padding iron, power head device, jockey, boring bar, the gear-hobbing machine cutterhead is provided with equal-height padding iron, and the gear-hobbing machine lathe bed connects power head device, and power head device is connected with boring bar by jockey.
Compared with prior art, the invention has the beneficial effects as follows:
Use after testing this method two hole site precision can reach in the 0.1mm, realize the high accuracy manufacturing of large-scale workpiece two ends axis hole.
