Abstract
The invention discloses a metal processing technique for a universal joint fork of a transmission shaft, comprising the following steps: firstly, using a numerical control lathe and an outer-circle turning clamp to sequentially turn an outer circle and an end surface, chamfer an end surface angle and drill a center hole; secondly, using a combined drilling machine and a lug-drilling clamp to drill two lugs; thirdly, using a numerical control milling machine and a lug-boring clamp to bore two lugs; fourthly, using the numerical control lathe and a clamping-spring-slot turning clamp to sequentially cut a clamping spring slot and turn the outer sides of two lugs; and fifthly, removing the tip corner and burr and chamfering two lug corners. The metal processing technique for a universal joint fork of a transmission shaft can greatly improve the size accuracy and the product quality of the metal processing of the universal joint fork of the transmission shaft, thereby eliminating the processing error of the parts, improving the working efficiency and reducing the production cost and the working intensity.
Description
Technical field
The present invention relates to driving shaft universal joint fork metalworking technology.
Background technology
The instructions for use of vehicle driving shaft assembly is more special, and it needs rotation at a high speed when transmitting moment of torsion.Along with people to Automobile Design hommization, more and more higher to the requirement of the riding comfortableness of automobile, the automobile related industries is also more and more higher to the requirement of the dynamic balance accuracy of driving-shaft assembly and residual unbalance, value.Original driving shaft universal joint fork metalworking technological process is to adopt common stand-alone device to process, and this technological process comprises following ten procedure of processings:
One, use upright drill and brill earhole anchor clamps to bore two earholes;
Two, use diamond fine boring machine and boring earhole anchor clamps heavy boring two earholes;
Three, use copying lathe and the rough turn cylindrical of turning anchor clamps, end face to reach (end face) angle;
Four, use copying lathe and turning anchor clamps finish turning cylindrical, end face to reach (end face) angle;
Five, use golden steel boring machine and boring earhole anchor clamps half right boring two earholes, right boring two earholes;
Six, use double column milling machine and mill the earhole anchor clamps and mill two ear lateral surfaces;
Seven, use lathe and car jump ring groove anchor clamps to cut the jump ring groove;
Eight, use two earhole angles of upright drill and the angle of falling earhole anchor clamps;
Nine, use lathe and scroll chuck drill centers;
Ten, use file to remove wedge angle, burr.
The major defect of above-mentioned processing technology is: ⑴ converted products dimensional accuracy is not high, causes assembly assembling back residual unbalance, value excessive, and design accuracy is difficult for guaranteeing that production efficiency is low; ⑵ process cycle is long, takes people, time-consuming, effort, can not satisfy the actual production demand; ⑶ it is long that switch (produce and the prepare) time, do not meet the requirement of lean production mode.
Summary of the invention
The object of the present invention is to provide that a kind of working (machining) efficiency is higher, the dimensional accuracy that can improve workpiece to be machined, eliminate the driving shaft universal joint fork metalworking technology of workpiece machining error.
For achieving the above object, driving shaft universal joint fork metalworking technology of the present invention comprises the steps:
One, use numerically controlled lathe and turning anchor clamps successively turning, end face, fall end face angle, drill centers;
Two, use combination drilling machine and brill earhole anchor clamps to bore two earholes;
Three, use CNC milling machine and boring earhole anchor clamps boring two earholes;
Four, use numerically controlled lathe and car jump ring groove anchor clamps to cut jump ring groove, car two ear lateral surfaces successively;
Five, remove earlier wedge angle, burr, fall two earhole angles again.
Driving shaft universal joint fork metalworking technology of the present invention has been rearranged operation, and use numerical control device (numerically controlled lathe, drilling machine, milling machine etc.), has following advantage: 1, can guarantee element precision to greatest extent, owing to cancelled roughing, therefore avoided work thick in the past, repeated clamping, location when fine finishining is switched, make the location unifying datum, therefore the various accumulations of error that cause because of location benchmark conversion in the time of can eliminating metalworking, the dynamic balancing quality that guarantees to assemble rear propeller shaft assy. to greatest extent.2, original ten procedures are reduced to five processes, cancellation roughing, directly on a certain operation with machined surface machine-shaping, optimized the metalworking technological process, make whole processing step still less (flow process is shorter) thereby, more easy to operate enhancing productivity, reduce lot of manpower and material resources, simultaneously greatly reduce processing cost and labour intensity, saved processing charges.3, shortened switching (produce and the prepare) time.In a word, driving shaft universal joint fork metalworking technology of the present invention can improve the dimensional accuracy and the product quality of driving shaft universal joint fork metalworking, eliminates part's machining errors, raises labour efficiency, and reduces production costs and labour intensity.
The instrument that uses when removing wedge angle, burr in the described step 5 is pneumatic emery wheel, and the instrument that uses when falling two earhole angles is little beakiron.
Used file to remove wedge angle, burr, efficient is very low in the past, now changes into using pneumatic emery wheel to remove wedge angle, burr, has improved production efficiency greatly.Used upright drill to fall two earhole angles in the past, complicated operation, efficient is lower, changes into using little beakiron to fall behind the two earhole angles, and easy and simple to handle, efficient is higher.
The specific embodiment
Driving shaft universal joint fork metalworking technology of the present invention comprises the steps:
One, use numerically controlled lathe and turning anchor clamps successively turning, end face, fall end face angle, drill centers;
Two, use combination drilling machine and brill earhole anchor clamps to bore two earholes;
Three, use CNC milling machine and boring earhole anchor clamps boring two earholes;
Four, use numerically controlled lathe and car jump ring groove anchor clamps to cut jump ring groove, car two ear lateral surfaces successively;
Five, use pneumatic emery wheel to remove wedge angle, burr earlier, re-use two earhole angles of little beakiron.
Driving shaft universal joint fork metalworking technology of the present invention has been rearranged operation, and use numerical control device (numerically controlled lathe, drilling machine, milling machine etc.), has following advantage: 1, can guarantee element precision to greatest extent, owing to cancelled roughing, therefore avoided work thick in the past, repeated clamping, location when fine finishining is switched, make the location unifying datum, therefore the various accumulations of error that cause because of location benchmark conversion in the time of can eliminating metalworking, the dynamic balancing quality that guarantees to assemble rear propeller shaft assy. to greatest extent.2, original ten procedures are reduced to five processes, cancellation roughing, directly on a certain operation with machined surface machine-shaping, optimized the metalworking technological process, make whole processing step still less (flow process is shorter) thereby, more easy to operate enhancing productivity, reduce lot of manpower and material resources, simultaneously greatly reduce processing cost and labour intensity, saved processing charges.3, shortened switching (produce and the prepare) time.
In a word, driving shaft universal joint fork metalworking technology of the present invention can improve the dimensional accuracy and the product quality of driving shaft universal joint fork metalworking, eliminates part's machining errors, raises labour efficiency, and reduces production costs and labour intensity.
