Abstract
The invention discloses a transmission shaft spline shaft metal processing technique. The processing technique comprises the following steps of: performing thermal refining by using a thermal refining automatic line; milling a small end surface by using a milling and drilling machine, and drilling centre bores at two ends; performing fine turning by using a numerically controlled lathe; milling a spline by using a numerical control spline milling machine; removing front points and burr; and performing mid frequency induction hardening by using a mid frequency induction hardening machine. The processing technique can guarantee the part accuracy to the maximum extent, eliminate various errors caused by position reference conversion, shortens the whole metal processing flow, reduce a large number of manpower and material resources, greatly reduce the processing cost, reduce the labor intensity, improve the working efficiency, and save processing cost.
Description
Technical field
The invention belongs to the Machining Technology field, relate in particular to a kind of splined driveshaft axle metalworking technology.
Background technology
The instructions for use of vehicle driving shaft assembly is more special; It needs rotation at a high speed when transmitting moment of torsion; And Along with people's to the Automobile Design hommization, to the riding comfortableness of automobile require increasingly high, also increasingly high to the requirement of the dynamic balance accuracy of driving-shaft assembly and residual unbalance, value.Existing power transmission shaft spindle nose adopts common stand-alone device to process, and processing process amounts to ten five processes, is followed successively by:
⑴, utilize shaft furnace to carry out normalized treatment;
⑵, use special fixture are clamped on the drilling and milling machine, mill both ends of the surface, beat microcephaly's centre bore;
⑶, use universal fixturing carry out rough turn microcephaly's cylindrical at copying lathe;
⑷, use universal fixturing are beaten big end centre bore on lathe;
⑸, use universal fixturing, at the copying lathe big end cylindrical of getting on the bus;
⑹, use universal fixturing are at first finish turning of copying lathe microcephaly cylindrical;
⑺, utilize salt bath furnace to carry out modifier treatment;
⑻, use universal fixturing are repaiied center lapping on special purpose lathe;
⑼, use universal fixturing, finish turning microcephaly cylindrical on lathe;
⑽, use universal fixturing carry out chamfering, grooving operation on lathe;
⑾, use universal fixturing mill spline on spline miller;
⑿, utilize the mid frequency induction hardening lathe to carry out mid frequency induction hardening;
⒀, use universal fixturing utilize cylindrical grinder mill spline cylindrical;
⒁, use universal fixturing utilize lathe finish turning major part cylindrical;
⒂, go wedge angle, burr operation at last.
Mainly there is following shortcoming in above-mentioned technological process:
⑴, converted products dimensional accuracy are not high, cause assembly assembling back residual unbalance, value excessive, and design accuracy is difficult for assurance, and production efficiency is low;
⑵, this process cycle are long, take people, time-consuming, effort, can not satisfy the actual production demand;
⑶, switching (produce and the prepare) time is long, does not meet the requirement of lean production mode.
Summary of the invention
The present invention provides the splined driveshaft axle metalworking technology that a kind of machining accuracy is high, assembly assembling back residual unbalance, value is little, production efficiency is high in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: splined driveshaft axle metalworking technology may further comprise the steps:
⑴, the modified transfer matic of use carry out modifier treatment;
⑵, use drilling and milling machine mill small end face, beat the two ends centre bore;
⑶, use numerically controlled lathe finish turning cylindrical;
⑷, use numerical control spline miller mill spline;
⑸, remove wedge angle, burr;
⑹, use mid frequency induction hardening lathe carry out mid frequency induction hardening.
Said step ⑵, ⑶, ⑷ use the universal fixturing of relevant device to carry out clamping respectively.
Removing wedge angle, the employed instrument of burr among the said step ⑸ is pneumatic emery wheel.
Adopt technique scheme, the present invention is reduced to six procedures with original ten five processes, and uses modern numerical control device and building-block machine in a large number, has following technique effect:
, be used " a kind ofly in processing power transmission shaft process, can obviously improve part processing precision and efficiency; reduce production costs with labour intensity add two symmetrical muscle at the splined shaft nest " patented technology " power transmission shaft of spindle nose nest reinforcement " (patent No. is ZL 200620134969.9); Can guarantee element precision to greatest extent, eliminate the various errors that cause because of the positioning reference conversion;
⑵, wherein adopt pneumatic emery wheel to replace file to go wedge angle, burr operation, and whole metalworking technological process shortened, can reduce lot of manpower and material resources; Greatly cut down finished cost; Reduce labour intensity, improved efficiency, practiced thrift processing charges.
⑶, heat treatment step is mentioned the first step in the metalworking technology, so both can carry out in advance to produce and prepare, can reduce the waste that carrying causes again, meet the requirement of lean production mode, adapt to the rapid market demand.
⑷, cancelled rough machined flow chart, directly on finish turning cylindrical operation with machined surface machine-shaping; Thick, fine finishining repeated clamping and location have been avoided in the past; Make positioning reference unified; This is not only and has reduced several procedures; Shorten switching (produce and the prepare) time, the more important thing is the various accumulations of error when eliminating metalworking, guaranteed the dynamic balancing quality of assembling rear propeller shaft assy. to greatest extent.
The specific embodiment
