Abstract

The invention relates to the field of machining, in particular to a space cross shaft hole machining method. The space cross shaft hole machining method comprises the following steps: performing precision casting; performing heat treatment; filing by a bench worker; performing rough machining; on a machining center, machining a workblank on a 0-degree dividing head, milling an upper end face, a cavity and a dustproof open slot, then performing semi-fine boring and fine boring to form a central through hole, performing semi-fine boring to form threaded holes, and tapping; on the machining center, rotating the dividing head by 180 degrees to mill an end face, expanding the central through hole on the boss of a workpiece, interpolating a clearance groove, performing fine milling to form a center hole, and detecting the coaxiality; on the machining center, rotating the dividing head by 90 degrees so that a hole needing to be machined goes away from a workbench, milling the end faces of the workpiece, milling holes, performing semi-fine milling on each threaded hole, and detecting the coaxiality; on the machining center, rotating the dividing head by 180 degrees again to mill a plane, boring a threaded bottom hole, and interpolating a threaded tool withdrawal groove; lathing external threads on a center lathe; on the center lathe, milling a key slot; checking. The space cross shaft hole machining method can guarantee the machining quality, the machining process is simple, and the production efficiency can be improved.

Description

Space cross shaft hole processing method
Technical field
The present invention relates to field of machining, be specifically related to space cross shaft hole processing method.
Background technology
A kind of height body part material ZG270--500.This part is key component, and difficulty of processing is large, and size and position accuracy demand are all higher, and viewed from the content of processing, the tool category of use is also very many, and its quality directly affects the overall performance of product.Therefore. this part is listed in key monitoring part, and initial workpiece processing must combining qualification and just can produce in batches by both sides.This part has following feature: (1) cross shaft hole is in spatialization and puts and non-intersect.(2) aperture size at cross shaft hole two ends is inconsistent, position accuracy demand high (4) the cross shaft hole sky of (3) each axis holes ask size and position accuracy demand high.(5) processing content is many, takies cutter many, needs precision compared with the fine boring tool of business, so it is more to take cutter.In addition, all thread Pilot holes and axis hole semifinishing size all need boring cutter, need the fine boring tool that the size of right boring must select adjustment accurate, stable.General processing method can not meet above-mentioned requirements.
Summary of the invention
In order to solve the problem, the invention provides one and can ensure crudy, process is simple, the space cross shaft hole processing method that can enhance productivity.
Space of the present invention cross shaft hole processing method, comprises the following steps:
The first step, hot investment casting, cast blank part;
Second step, heat treatment, adopts annealing to heat-treat blank;
3rd step, file is repaiied in pincers worker, repairs blank;
4th step, roughing, blank processes roughly location criterion, and removes excessive allowance;
5th step, work in-process in the heart, dividing head 0 0machining blanks, milling upper surface, die cavity, dust-proof open slot, then half right boring, right boring central through hole, half right boring screwed hole, and tapping;
6th step, in the heart, dividing head rotates milling 180 to work in-process 0end face, workpiece boss expands central through hole, interpolation undercut, right boring centre bore, and detects axiality;
7th step, in the heart, dividing head rotates 90 to work in-process 0the hole that needs are processed deviates from workbench, milling workpiece end face, hole milling, each screwed hole of half right boring, and tapping, detects axiality;
8th step, in the heart, dividing head rotates 180 to work in-process again 0milling flat, boring thread Pilot hole, interpolation Gewindefreistiche, and tapping;
9th step, external threading on engine lathe;
Tenth step, on machine tool, keyseat;
11 step, carries out surface treatment to workpiece;
12 step, inspection.
The present invention can ensure crudy, and process is simple, can enhance productivity.
Detailed description of the invention
Space of the present invention cross shaft hole processing method, comprises the following steps:
The first step, hot investment casting, cast blank part;
Second step, heat treatment, adopts annealing to heat-treat blank;
3rd step, file is repaiied in pincers worker, repairs blank;
4th step, roughing, blank processes roughly location criterion, and removes excessive allowance;
5th step, work in-process in the heart, dividing head 0 0machining blanks, milling upper surface, die cavity, dust-proof open slot, then half right boring, right boring central through hole, half right boring screwed hole, and tapping;
6th step, in the heart, dividing head rotates milling 180 to work in-process 0end face, workpiece boss expands central through hole, interpolation undercut, right boring centre bore, and detects axiality;
7th step, in the heart, dividing head rotates 90 to work in-process 0the hole that needs are processed deviates from workbench, milling workpiece end face, hole milling, each screwed hole of half right boring, and tapping, detects axiality;
8th step, in the heart, dividing head rotates 180 to work in-process again 0milling flat, boring thread Pilot hole, interpolation Gewindefreistiche, and tapping;
9th step, external threading on engine lathe;
Tenth step, on machine tool, keyseat;
11 step, carries out surface treatment to workpiece;
12 step, inspection.
Due to the existence of Fixture Location Error and the dividing head error of division in work in-process heart process, rotary position is at O 0with 180 0under two states, the axis of part can not overlap completely, therefore, part time want O 0with 180 0use different coordinates to be biased respectively, namely use G54 and 1,355 two different co-ordinate zero point machining programming.To carry out after fixture and dividing head connect beating table centering, fixture 90 0the V-arrangement centre of location must ensure vertical with locating surface.
The present invention can ensure crudy, and process is simple, can enhance productivity.
