Description
Technical field:
The present invention relates to a kind of processing technology of mechanical part, particularly a kind of processing method of housing for timing gear.
Background technology:
Housing for timing gear generally is arranged in the front end of engine as a cavity body, and diesel engine gear trains such as crankshaft toothed wheel, cam wheel, fuel injection pump gear, air compressor machine gear are enclosed in the cavity, realizes the motion of engine interior member by gear drive.The reasonability of its structure and reliability have significant effects to economy, reliability and the reduction noise of engine.Therefore, the height of housing for timing gear machining accuracy directly affects the quality and the Diesel engine reliability of operation of the supporting installation of Diesel engine car load.And the processing method of housing for timing gear is at present: main engine plants provide processing drawing and blank, require roughing to locate according to drawing with the blank anchor point, all sizes are set up coordinate dimension with ф A center, a hole, and this hole need process, first machining benchmark hole ф A and the attached hole Φ B that helps, with this location, two holes, process other holes, at the bottom of the working (machining) efficiency, each irregular differing of the relative blank shape of processing dimension, and precision is inconsistent, and efficiency of assembling is low.In addition, processing a kind of timing gears tooth needs specialized apparatus, processes the equipment of different gear chamber and can't unify, and causes the processing cost height.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of processing method of housing for timing gear, this processing method production efficiency height, gear chamber precision height, the high conformity produced.
As above design, technical scheme of the present invention is: a kind of processing method of housing for timing gear is characterized in that: carry out according to the following step: 1. utilize milling machine to rough mill the gear chamber interarea successively; 2. rough mill the gear chamber installed surface; 3. finish-milling gear chamber interarea; 4. finish-milling gear chamber installed surface; 5. the work in-process heart is made with extra care the gear chamber installed surface, and distance two installing holes are farthest processed each hole of gear chamber periphery simultaneously as the location datum hole on the selection installed surface; 6. the work in-process heart is made with extra care the gear chamber interarea, dot center hole, brill bottom outlet, chamfering, tapping, each hole of heavy boring, each hole of right boring; 7. mill the end face of gear chamber; 8. mill the side of gear chamber; 9. mill the bottom surface of gear chamber; 10. bore end face hole, aperture chamfering, the tapping of attacking gear chamber; (11) brill is attacked the gear chamber side, is bored lateral aperture, counterbore; (12) secondary bores gear chamber lateral aperture, chamfering, tapping; (13) cleaning, pressure testing.
Above-mentionedly rough mill the gear chamber interarea and rough mill the gear chamber installed surface and adopt X53K.
Above-mentioned finish-milling gear chamber interarea adopts TH716, and finish-milling gear chamber installed surface adopts XQ2010.
Above-mentioned refining gear chamber installed surface and refining gear chamber interarea adopt KT1500.
X62W is adopted in the above-mentioned end face that mills gear chamber, the side of milling gear chamber, the bottom surface of milling gear chamber.
Above-mentioned brill is attacked the end face of gear chamber and is bored the side of attacking gear chamber and adopt Z3050*16.
Advantage of the present invention is: the present invention selects on the installed surface distance two installing holes farthest as the location datum hole, porose can processing simultaneously, the phenomenon that does not have secondary operations, accurate positioning, clamping is quick, and productivity ratio improves, and original per tour is produced 30 per tour nowadays and produced 120, product percent of pass 99.8%, high conformity.On main engine plants' assembly line, 80 chassis are assembled in original per tour, and per tour now can be assembled 100 chassis, has improved efficiency of assembling, and gear chamber production share is greatly promoted.
