Abstract
A new technology for machining the vortex chamber hole of cylinder cover of diesel engine features that before the vortex chamber hole is machined, the oil sprayer hole is pre-machined, then the vortex chamber hole is machined and the oil sprayer hole is finish-machined. The invention solves the problems of difficult chip removal and zero cutting in the traditional vortex chamber hole processing, lightens the labor intensity of workers, reduces the working procedure processing time, obviously improves the surface roughness of the hole, prolongs the abrasion period of a cutter and simultaneously improves the processing quality of the oil sprayer hole.
Description
Technical field
The present invention relates to the processing technology of cylinder cover for diesel engine, particularly cylinder head vortex chamber hole method for processing and step.
Background technique
The hole, vortex chamber of vortex diesel engine cylinder head and the common structure of oil injector hole as shown in Figure 1, its precision is higher, thereby processing technology is required also tighter.Traditional processing technology is elder generation's processing hole, vortex chamber on vertical drilling machine (an existing casting preformed hole), the reprocessing oil injector hole, and as shown in Figure 2, specifically processing technology is that (1) bores the hole, vortex chamber with twist bit; (2) slightly expand vortex chamber's spherical pore with Form tool; (3) with the compound expansion of compound cornish bit insert hole, hole, vortex chamber and vortex chamber's spherical pore; (4) with the compound hinge of combination cutter insert hole, hole, vortex chamber and vortex chamber's spherical pore; (5) with the compound brill oil injector hole of composite drill bit; (6) with the compound hinge oil injector hole of combination cutter.There is following shortcoming in this processing technology: (1) is owing to be vertical processing, so the chip removal difficulty, needs artificial regularly chip removal, and manufacturing efficiency is low, and activity time is longer; (2) because the chip removal difficulty causes that vortex chamber's machined surface roughness is relatively poor, the tool wear cycle shortens and well damage; When (3) compound expansion, hinge vortex chamber spherical pore, owing to have " cutting zero point " (cutting speed is zero point), so cutting resistance is quite big, operator's labor intensity is big.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing processing technology, provide a kind of and reduce labor intensity, reduce machining period, can improve hole, the vortex chamber new process for processing of machining accuracy again.
Technological scheme of the present invention is: first preprocessing oil injector hole before the processing of hole, vortex chamber, and then processing hole, vortex chamber and fine finishing oil injector hole, and concrete processing technology is: (1) uses twist bit preboring oil injector hole; (2) slightly expand vortex chamber's spherical pore with Form tool; (3) with the compound expansion of compound cornish bit insert hole, hole, vortex chamber and vortex chamber's spherical pore; (4) with the compound hinge of combination cutter insert hole, hole, vortex chamber and vortex chamber's spherical pore; (5) with the compound expansion oil injector hole of compound cornish bit; (6) with the compound hinge oil injector hole of combination cutter.
With twist bit preboring nozzle opening the time, the size of pre-drilled is cut zero point for well to remove.
Processing technology of the present invention has the following advantages:
(1) the oil injector hole preprocessing only needs to insert a little beakiron before the processing of hole, vortex chamber, and this little beakiron is that the processing oil sprayer is installed screw bottom outlet lathe in the tratitional technology, does not therefore increase personnel and equipment, and the original production line is not had big influence.
(2) preprocessing of oil injector hole has solved the chip removal difficult problem in the processing of hole, vortex chamber, has alleviated working strength of workers, has reduced working procedure processing man-hour; The removal at " cutting zero point " makes the processing in hole, vortex chamber become brisk, and the roughness of finished surface is significantly improved, by original
Bring up to
The wear-out period of cutter significantly extends, and the damage of cutter obviously reduces, and has also improved the quality of processing of oil injector hole simultaneously.
(3) though increased the preboring oil injector hole, as a whole, productivity still increases.Since balance the man-hour of former inter process, improved personnel's Utilization ratio, therefore, also reduce to some extent during whole lineman.
