Description
Technical field
The present invention relates to the cartridge housing manufacture field of turbocharger, particularly a kind of processing method of turbo-charger bearing shell.
Background technology
Turbocharger is mounted in the parts that run up on engine, and row's environmental protection falls again in both energy efficiencies.Wherein cartridge housing is the strength member of turbocharger, and the crudy quality of dead eye, directly has influence on these the whether working properly of part that run up.
Fig. 1 is the structural representation of cartridge housing, as shown in the figure, the Chi of cartridge housing dead eye 103 cun of Gong Cha ﹑ form and position tolerance and surface roughness requirements higher, these Chi cun of Gong Cha ﹑ form and position tolerances, roughness processing is not easy to ensure.At present, cartridge housing dead eye reaches requirement by the method for grinding or honing, and the procedure of processing of the method for existing Honing process cartridge housing comprises:
Step one: clamping for the first time, this cartridge housing small end 12 rough turn;
Step 2: second time clamping, the large end 11 of this cartridge housing rough turn;
Step 3: clamping for the third time, this cartridge housing small end 12 of finish turning;
Step 4: No. the 4th clamping, the large end 11 of this cartridge housing of finish turning, dead eye 103 made allowance.
Step 5: No. the 5th clamping, milling circumferential flange face, processes each hole and screw.
Step 6: No. the 6th clamping, honing dead eye is to figure requirement on plover mill machine.
Step 7: deburring.
Step 8: cleaning.
Step 9: comprehensive test.
As the method with grinding, need increase manufacturing procedure, its processability is poor, and part qualification rate is low and extend the production cycle; Due to cartridge housing Shi Zhong ﹑ small lot batch manufacture, as the processing method with honing, a plover mill machine need be increased, and add manufacturing procedure, which adds processing cost and extend the production cycle.
Summary of the invention
For solving the problem, the invention provides a kind of processing method of turbo-charger bearing shell, while ensureing machining accuracy, shortening the process-cycle, enhancing productivity.
For achieving the above object, technical scheme of the present invention is as follows:
The processing method of turbo-charger bearing shell of the present invention, comprises the following steps:
Step one, the large end cylindrical of clamping cartridge housing, the small end of turnery processing cartridge housing;
Step 2, the small end cylindrical of clamping cartridge housing, the large end of first turning cartridge housing, reface machining shaft bearing bore, retains surplus, then adopts reamer ream dead eye;
Step 3, deburring;
Step 4, cleaning;
Step 5, comprehensive test.
Preferably, described reamer comprises handle of a knife, adjusting device, knife bar, sliver and blade, and described blade is arranged on sliver, and described blade is adjustable to the distance of the pivot axis of sliver; Described sliver is fixedly connected with knife bar; Described knife bar is connected by described adjusting device with handle of a knife, the concentricity of the pivot axis of the adjustable handle of a knife of described adjusting device and the pivot axis of knife bar.
Preferably, described blade adopts cubic boron nitride blade.
The processing method of turbo-charger bearing shell of the present invention, namely meets the requirement on machining accuracy of cartridge housing dead eye, improves product percent of pass, shorten the production cycle again, improve production efficiency, and reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of cartridge housing;
Fig. 2 is the schematic diagram of the reamer of machining bearing columella bearing bore.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details.
See Fig. 1, the processing method of turbo-charger bearing shell of the present invention, comprises the following steps:
Step one, the large end cylindrical 101 of clamping cartridge housing, the small end 12 of turnery processing cartridge housing, is machined to design drawing requirement by the small end 12 of cartridge housing;
Step 2, the small end cylindrical 102 of clamping cartridge housing, the large end 11 of first turning cartridge housing, is machined to drawing requirement, reface machining shaft bearing bore 103, retains surplus, surplus 0.2 ~ 0.3mm, then adopts reamer ream dead eye 103, is machined to design drawing requirement;
Step 3, deburring;
Step 4, cleaning;
Step 5, comprehensive test.
Can when the small end 12 of turnery processing cartridge housing in above-mentioned steps one, turning roughing dead eye 103, retain surplus, surplus is 1.8 ~ 2.0mm.
First time clamping is carried out in above-mentioned steps one, turning completes the fine finishining of the small end 12 of cartridge housing, then carries out second time clamping in step 2, and turning completes the fine finishining of the large end 11 of cartridge housing, and complete the semifinishing of cartridge housing 103, then complete the fine finishining of dead eye 103 by reamer.Completed the processing of this part by twice clamping, and in clamped one time, complete the fine finishining of dead eye 103 and large end 11 all the other sizes.Adopt the processing method of turbo-charger bearing shell of the present invention, decrease clamping times, shorten the production cycle, decrease resetting error, improve product quality and qualification rate, reduce production cost.
See Fig. 2, reamer shown in figure can be used for ream dead eye 103 in above-mentioned steps two, described reamer comprises handle of a knife 1, adjusting device 2, knife bar 3, sliver 4 and blade 5, and described blade 5 is arranged on sliver 4, and the distance of the pivot axis of described blade 5 to sliver 4 is adjustable; Described sliver 4 is fixedly connected with knife bar 3; Described knife bar 3 is connected by adjusting device 2 with handle of a knife 1, the concentricity of the pivot axis of the adjustable handle of a knife 1 of described adjusting device 2 and the pivot axis of knife bar 3.Knife bar 3, sliver 4 and blade 5 rotate with the rotation of handle of a knife 1, because sliver 4 is fixedly connected with knife bar 3, therefore adjustable sliver 4 pivot axis with the concentricity of the pivot axis of handle of a knife 1.Described sliver 4 can play the guiding role when reamer inserts dead eye 103.Described handle of a knife 1 is arranged on lathe.
Before adopting the reamer in Fig. 2 to be used for the processing of dead eye 103, first by the distance of the pivot axis of tool setting gauge adjustment blade 5 to sliver 4, make the dimensional requirement of hole in piece part in its size to design drawing; Again on lathe, by adjustment adjusting device 2, the circle of reamer is beated to designing requirement.
Described blade 5 adopts cubic boron nitride blade.
Adopt the reamer machining shaft bearing bore 103 in Fig. 2, be conducive to the dimensional accuracy and the surface roughness that ensure bearing housing hole, improve product percent of pass.
Above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
