Abstract
The invention relates to the field of machining, in particular to a method for machining a large-diameter thin-wall coupling shaft. The method includes the steps that a big outer circle, end faces and a deep inner hole are machined in a numerically controlled lathe through a finish turning clamp, and when the inner hole is subjected to finish turning, a lengthened cutter bar is adopted for machining the deep inner hole; during machining of an outer molded surface, a special finish turning clamp for the outer molded surface is adopted for tensioning the inner hole, pressing the small end face and performing finish turning on the big end face, an inner rabbet and a web molded surface, the big end face is pressed, and the outer circle and the inner hole are subjected to finish turning; the big end face is bored, sixty holes with the diameter of 7mm and sixty holes with the diameter of 8mm are formed in the big end face, the location degree of the holes is required to be 0.05, a combined clamp is adopted for pressing the edge of the big outer circle and forming the one hundred twenty holes in a jig boring machine through drilling and boring; grooves, inclined holes, inclined grooves and radial grooves are machined. Deformation of the big outer circle and the end faces of the workpiece and the wall thickness of the web molded surface can be guaranteed, machining efficiency is improved, product quality is guaranteed, and product cost is lowered.
Description
Technical field
The present invention relates to field of machining, be specifically related to large diameter thin wall Coupling Shaft processing method.
Background technology
Coupling Shaft structure is extremely complex, not only workpiece big outside diameter size relatively big and also axial dimension is longer and endoporus relatively
Deeply.Diameter means that the most greatly work pieces process deforms the most bad control.Easily shake during endoporus deep processing cutter, cutter relieving, makes hole size
It is difficult to ensure card with roughness, owing to being to process major diameter Coupling Shaft first, there is no direct referential processing experience, can only be in processing
In grope, summing up experience.Find out the factor affecting workpiece deformation, in order to outer mold surface, big cylindrical and end face, Milling Machining in finish turning
Many places skewed slot, inclined hole and radial slot and better control over workpiece deformation after shot-peening in reparation to big cylindrical and seam, protect
Card cylindrical, diameter of bore size and benchmark is beated 0.013 and the requirement of perpendicularity 0.01.
Coupling Shaft material is TC4 titanium alloy, and outside dimension is relatively big, and axial dimension is longer, and thin-walled thickness is only 3mm, web
Profile wall thickness dimension tolerance is tight, and difficult processing ensures.Large end face diameter 7mm, diameter 8mm installing hole are respectively arranged with 60, due to wall thickness relatively
Thin, add and easily cause man-hour large end face to deform.Have screw thread and spline on cylindrical, degree face and cylindrical have many places skewed slot, inclined hole and
Radial slot, adds and easily causes man-hour workpiece to deform.Endoporus has bulb groove and groove at 4, and small end face has end face groove at 4.Interior hole machined
Shi Rongyi shakes cutter, cutter relieving, makes hole size and roughness be difficult to ensure card.Work pieces mate dimensional accuracy and technical conditions require height, chi
Very little minimal tolerance is 0.013, and perpendicularity, axiality are 0.01, and beating benchmark is 0.013, is difficult to processing and ensures.Need group's system
Outer mold surface fixture in finish turning, lengthened tool arbor, inner stopper measuring tool, numerical programming program, select suitable cutter, to control work pieces process
Deformation and processing deep and long hole shake cutter cutter relieving problem, it is ensured that cylindrical, hole size precision and technical conditions requirement.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of and ensure that the big cylindrical of workpiece and the deformation of end face and web type
Face wall thickness dimension, improves working (machining) efficiency, it is ensured that product quality, reduces the large diameter thin wall Coupling Shaft processing side of production cost
Method.
Large diameter thin wall Coupling Shaft processing method of the present invention, comprises the following steps:
The first step, big cylindrical, end face and the processing of deep endoporus, use lathe finish fixture, numerically controlled lathe is processed, in finish turning
Lengthened tool arbor is used to process deep endoporus during hole；
Second step, the processing of outer mold surface, use special finish turning outer mold surface fixture tensioner endoporus to compress small end face finish turning large end face, interior
Seam, web profile, compress large end face fine turning outer circle and endoporus；
3rd step, large end face bore hole, large end face diameter 7mm, diameter 8mm hole be respectively arranged with 60, and hole location requires 0.05, uses
Built-up jig compresses big outer circular edge and bores 120 holes of boring at jig boring machine；
4th step, groove, inclined hole, skewed slot, the processing of radial slot, bulb groove, inclined hole, skewed slot, radial slot operation at 4 are merged
Clamped one time centering, is carried out at five-axis machining center；
5th step, the processing of end face groove, at Coupling Shaft 4, end face groove is only 0.05 to centre distance dimensional tolerance, position degree requirement
0.15, slotting machine is processed, first rules at Working position, then centering slotting tool center, by clamping workpiece in work
Centering workpiece centre and 4 groove location on platform, meet drawing requirement through detection workpiece size and position degree degree after being processed by test.
The present invention ensure that the big cylindrical of workpiece and the deformation of end face and web profile wall thickness dimension, improves and adds work efficiency
Rate, it is ensured that product quality, reduces production cost.
