Abstract
The invention discloses a method for processing a multi-axis hole system of a differential shell. The method comprises the following steps of: a, firmly pressing a positioning column on a worktable of a vertical machining center, and aligning the centre of an outer circle of a positioning mandrel; b, processing holes in a differential cover; c, processing a differential shell body; and d, assembling the differential shell. Four holes in the differential cover and the differential shell are processed respectively, and a label corresponding assembly mode is adopted, so the assembly requirement of string holes on high coaxiality is also ensured while the problem that the string holes are difficult to be positively and laterally parallel to a central reference hole is solved; and practice proves that positive and lateral parallelisms of the string holes of the differential shell obtained by the method to the central reference hole are less than or equal to 0.03mm, so the machining accuracy is greatly improved.
Description
Technical field
The present invention relates to the Work piece processing method of mechanical field, the processing method of particularly a kind of differential housing multiaxis hole system.
Background technology
Shown in accompanying drawing 1, differential housing is combined by a differential lid 1 of cast iron and the differential shell body 2 of steel material, and 4 string holes are along the circumferential direction arranged.Former processing method for the string hole is: differential lid 1 is after benchmark combines with differential shell body 2 with the central standard hole; Locate with the central standard hole; Processing 4 is the ￠ 25H7 string hole that benchmark is uniformly distributed with the centre bore; The string pitch-row is long from 142 mm, and this processing method can well guarantee the axiality of 4 string apertures.Because the hole is little, the string pitch-row is from long, and after processing, string hole axiality can reach drawing requirement, but string hole and datum hole just, side direction is parallel overproof bigger, generally at 0.1～0.16mm, can not satisfy and design and matching requirements.
To above-mentioned deficiency, a kind of new processing method need be provided, make its can solve ￠ 25H7 string hole to the center datum hole just, the parallel difficulty of side direction the time, the same assembling demand that guarantees string hole self to high-axiality.
Summary of the invention
In view of this, the purpose of this invention is to provide the processing method of a kind of differential housing multiaxis hole system, make its can solve on the differential housing string hole to the center datum hole just, the parallel difficulty of side direction the time, the same assembling demand that guarantees string hole self to high-axiality.
The objective of the invention is to realize through following technical scheme: the processing method of a kind of differential housing multiaxis hole system may further comprise the steps:
A, elder generation compress reference column on the vertical machining centre workbench, said reference column comprises positioning core axle and the support ring that is provided with along the positioning core axle circumferencial direction, and annular slot to make way is set between positioning core axle and the support ring; The cylindrical center of centering positioning core axle then;
B, the differential processing that covers the hole: differential lid is assemblied on the reference column and compresses, set machine tool program make its successively machining hole I, hole II, hole III and hole IV and processing sequence carried out label to predetermined requirement, take off differential lid then;
C, the processing of differential shell body: keep reference column and machine tool program constant; Differential shell body is installed on the reference column; The location also compresses; Starting machine tool program makes it machining hole V, hole VI, hole VII and hole VIII and to processing sequence label radially, is taken off differential shell body then to predetermined requirement successively;
D, assemble differential housing: is datum hole with differential lid and differential shell body with center separately; Load onto mandrel; According to the hole I hole V, hole II are constituted string hole to hole VII, hole IV to the mode of carrying out of hole VIII to hole VI, hole III, proofread and correct after coaxial two parts are assembled and get final product.
Further, on the support ring of said reference column chip removal mouth is set also;
Further, the positioning core axle center of said reference column is provided with through hole vertically.
Beneficial effect of the present invention: the processing method of a kind of differential housing multiaxis of the present invention hole system; Compare existing processing method; Owing to adopt on differential lid and the differential housing four holes to process and adopt the mode of the corresponding assembling of label respectively; Make its can solve the string hole to the center datum hole just, the parallel difficulty of side direction the time, the same assembling demand that guarantees string hole self to high-axiality facts have proved; Adopt the differential housing of this processing method gained respectively go here and there the hole to the center datum hole just, side direction is parallel smaller or equal to 0.03mm, machining accuracy improves greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is the structural representation of differential housing;
Fig. 2 is the structural representation of reference column according to the invention;
The assembling sketch map of differential lid and reference column when Fig. 3 is processing;
