The object of the invention is to have come by following technical solution, the machine-tooled method of described a kind of angle transmission-gear box box body hole system, this machine-tooled method comprises the steps:
A) selected positioning datum and process equipment: with casing one stent cover for positioning reference plane, select the horizontal machine tool with any anglec of rotation workbench as machining tool;
B) set up initial workpiece initial point to be biased: casing locate on platen and after clamping, measures initial casing coordinate origin, thus the initial point setting up initial casing is biased;
C) on casing, axis hole is processed: first process input shaft bore by machining tool in the front of casing, then workbench is rotated counterclockwise the angle at an inclination angle around pivot, and then the processing that corresponding distance can complete casing angle of declination output shaft is moved in machine tool site.
The present invention is preferably: in described step b), casing is located and the initial point be clamped on platen is placed on 0 1point, its coordinate is x 1, z 1, i.e. the absolute coordinate initial point of casing, when processing the output shaft of angle of declination 10 °, workbench is rotated counterclockwise 10 ° around pivot, and now Y-axis does not have the conversion of coordinate mark, only has x, and z-axis participates in rotary table Coordinate Conversion and calculates, and this to be just equivalent on casing 0 4point moves on the circle taking R as radius, after rotating 10 °, on casing 0 4point moves to 0 3the i.e. Working position of beveled aperture, now measures initial casing initial point biased 0 1point and 0 3the X of point, the distance of Y-direction, then cutter location moves the processing that corresponding distance can complete casing angle of declination output shaft.
The present invention shows through three-dimensional metering, and all technical meets drawing requirement, and complete machine test run gears meshing precision is good, product percent of pass >=97%, and economic benefit is very remarkable; Have and can improve casing precision, reduce scrappage, improve productivity effect, reduce the features such as production cost.

Detailed description of the invention
the present invention will be described in detail below in conjunction with the accompanying drawings and the specific embodiments: shown in Fig. 1,2, angle transmission-gear box casing 1 of the present invention, hole system on it at least comprises one perpendicular to the parallel input shaft bore 2 in antinose-dive leg face, one becomes a tilt angles relative to parallel input shaft bore, the intermediate shaft hole 4 that one parallel with input shaft bore 2 is also had as shown in the output shaft hole 3, figure of 10 degree.
The machine-tooled method of a kind of angle transmission-gear box box body hole system of the present invention, this machine-tooled method comprises the steps:
A) selected positioning datum and process equipment: with a stent cover F of casing 1 for positioning reference plane, select the horizontal machine tool with any anglec of rotation workbench as machining tool;
B) set up initial workpiece initial point to be biased: casing 1 locate on platen and after clamping, measures initial casing coordinate origin, thus the initial point setting up initial casing is biased, as shown in Figure 3;
C) on casing, axis hole is processed: first process input shaft bore 2 by machining tool 5 in the front of casing 1, then workbench is rotated counterclockwise the angle at an inclination angle around pivot, then the processing that corresponding distance can complete casing angle of declination output shaft is moved in machine tool site, as shown in Figure 4.
Shown in Fig. 4,5, the preferred embodiment of the invention is: described step b), and casing 1 is located and the initial point be clamped on platen is placed on 0 1point, its coordinate is x 1, z 1, i.e. the absolute coordinate initial point of casing, when processing the output shaft of angle of declination 10 °, workbench is rotated counterclockwise 10 ° around pivot, and now Y-axis does not have the conversion of coordinate mark, only has x, and z-axis participates in rotary table Coordinate Conversion and calculates, and this to be just equivalent on casing 0 4point moves on the circle taking R as radius, after rotating 10 °, on casing 0 4point moves to 0 3the i.e. Working position of beveled aperture, now measures initial casing initial point biased 0 1point and 0 3the X of point, the distance of Y-direction, then cutter location moves the processing that corresponding distance can complete casing angle of declination output shaft.
embodiment:
For certain model gear housing, see shown in Fig. 3,4, its output shaft and power shaft have the angle of declination of 10 ° in vertical plane, for ensureing gears meshing precision, reduce noise, impact, the processing of crossing axis hole system must be completed by clamped one time, ensure the gradient requirement of the Geometrical Tolerance Principle, particularly 0.03mm between axis.
Concrete technological process is: casing with F to stent cover for location basal plane, F is locating hole to two screws; Select Mazak NEXUS 8800-II for process equipment, setting workbench is when direction as shown in Figure 3, and the initial point of workpiece is placed on 0 1point, its coordinate is (x 1, z 1), i.e. the absolute coordinate initial point of workpiece, when to process have a down dip the output shaft of 10 ° time, workbench is rotated counterclockwise 10 ° around pivot; Y-axis does not have the conversion of coordinate mark, therefore only has x, and z-axis participates in rotary table Coordinate Conversion and calculates; Now just to be equivalent on workpiece 0 4point moves on the circle taking R as radius, after rotating 10 °, on workpiece 0 4point moves to 0 3namely the Working position of beveled aperture is shown in Fig. 4, now sees that Fig. 5 measures initial workpiece initial point biased 0 1point and 0 3the X of point, the distance of Y-direction, then cutter location moves the processing that corresponding distance can complete casing angle of declination output shaft, and can ensure the designing requirement such as gradient, axiality very well.
The present invention first positioning datum elects casing one stent cover as, and axle, to tie up in vertical plane crossing is converted to intersecting in horizontal plane like this.Secondly process equipment choosing has the horizontal Machining centers of any anglec of rotation, like this output axis relatively input axis have a down dip the processing at β angle be converted on horizontal Machining centers with initial workpiece initial point bias plane angle be β inclined-plane on hole characteristic processing problems.
The biased conversion of Workpiece zero point on horizontal Machining centers, namely casing is located on platen, after clamping, measures initial workpiece coordinate origin, and set up initial casing initial point and be biased, namely casing position in lathe coordinate system is determined.When worktable rotary β angle is to beveled aperture Working position, the biased calculating of casing initial point, is biased to the calculating of the new casing working origin on basis exactly with initial casing initial point.The relation of X, new, the old workpiece coordinate system initial point of Z-direction now can be found out by CAD mapping.
