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, particularly relate to method and the device of a kind of machining large rotary work piece 180 degree of axis holes.
Background technology
180 degree of axis holes of large revolving body workpiece are difficult to processing, as outlet slag fills with gudgeon hole.Because its tactical diameter is large, on centerline, distance center circle two ends are comparatively far away, cannot processing technology benchmark for two ends earhole.So the axiality requirement of holes cannot be ensured.Common processing method can only rely on line, then machines according to line with large-scale floor type boring machine.But line error is very large, usually cannot meet the higher workpiece of position degree requirement.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of this invention is to provide method and the device of a kind of machining large rotary work piece 180 degree of axis holes, realizing the precision manufactureing of two ends axis hole.
For achieving the above object, the present invention is achieved through the following technical solutions:
The method of machining large rotary work piece 180 degree of axis holes and a device, comprise the following steps,
1) power head device being arranged on gear-hobbing machine by quartering hole is installed on support;
2) some height errors are less than the equal-height padding iron of 0. 5mm, are arranged on cutterhead;
3) by work piece on equal-height padding iron, round positive by the endoporus of workpiece, levelling by datum end face, just looking for the circle in one of them gudgeon hole by platform initial scribes;
4) process diameter and the end face in gudgeon hole, one end with boring bar, utilize the separate electrical motor of power head device to drive and realize boring bar rotation, utilize lathe bed to realize feeding seesawing of guide rail, after completion of processing, bed piece is withdrawn into original state;
5) carry out accurate calibration by an accurately point tooth function for gear-hobbing machine lathe itself, cutterhead revolves turnback, repeats step 4);
The device of described machining large rotary work piece 180 degree of axis holes comprises gear-hobbing machine, equal-height padding iron, power head device, jockey, boring bar, gear-hobbing machine cutterhead is provided with equal-height padding iron, and 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:
Within using this method holes positional precision that 0.1mm can be reached after testing, realize the high accuracy manufacture of large-scale workpiece two ends axis hole.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in detail:
The method of machining large rotary work piece 180 degree of axis holes and a device, be shown in Fig. 1, Fig. 2, comprise the following steps,
1) power head device 3 being arranged on gear-hobbing machine by quartering hole is installed on support;
2) some height errors are less than the equal-height padding iron 1 of 0.5mm, are arranged on cutterhead;
3) workpiece 2 is placed on equal-height padding iron 1, round positive by the endoporus of workpiece 2, levelling by datum end face, just looking for the circle in one of them gudgeon hole by platform initial scribes;
4) process diameter and the end face in gudgeon hole, one end with boring bar 6, utilize the driving of the separate electrical motor 7 of power head device 3 to realize boring bar 6 and rotate, utilize lathe bed 4 to realize feeding seesawing of guide rail 5, after completion of processing, bed piece 4 is withdrawn into original state;
5) carry out accurate calibration by an accurately point tooth function for gear-hobbing machine lathe itself, cutterhead revolves turnback, repeats step 4).
The device of described machining large rotary work piece 180 degree of axis holes comprises gear-hobbing machine, equal-height padding iron 1, power head device 3, boring bar 6, gear-hobbing machine cutterhead is provided with equal-height padding iron 1, gear-hobbing machine lathe bed connects power head device 3, and power head device 3 is connected with boring bar 6 by jockey.
At the circular hole of workpiece 2 two ends processing diameter 4 meters, power head device 3 is arranged on gear-hobbing machine by quartering hole and is installed on support; 8 tile height errors are less than the equal-height padding iron 1 of 0.5mm, be arranged on cutterhead appropriate location, the workpiece 2 of 11 meters long is placed on equal-height padding iron 1, round positive by the endoporus of workpiece 2, levelling by datum end face, just looking for the circle in one of them gudgeon hole by platform initial scribes; Process diameter and the end face in gudgeon hole, one end with boring bar 6, utilize the driving of the separate electrical motor 7 of power head device 3 to realize boring bar 6 and rotate, utilize lathe bed 4 to realize feeding seesawing of guide rail 5, after completion of processing, bed piece 4 is withdrawn into original state; Carry out accurate calibration by an accurately point tooth function for gear-hobbing machine lathe itself, cutterhead revolves turnback, processing other end gudgeon hole.The axis hole circle center error of its processing of the workpiece 2 processed in this approach, in 1mm, meets need of production completely.
The present invention is applicable to the high accuracy manufacture realizing large-scale workpiece two ends axis hole, within using this method holes positional precision to reach 1mm after testing.
