Abstract

A kind of undercarriage bearing hole method for fine finishing, including finding out physical location of the undercarriage bearing hole under aircraft axes using laser tracker measurement, the theoretical coordinate value of bearing hole is run on numerically-controlled machine tool again, lathe is moved at undercarriage bearing hole, dual output processing head is installed on machine tool chief axis, the size that lose-lose is lifted one's head mutually is coordinated with undercarriage bearing hole, can satisfy the requirement of processing space;With again the knife bar of process tool, Cutting tool installation manner in the left side that lose-lose is lifted one's head, left side undercarriage bearing hole is processed;After the processing of left side, processing nut arbor, cutter are changed the outfit in the right side that lose-lose is lifted one's head, processing right side undercarriage bearing hole.The undercarriage bearing hole method for fine finishing can preferably improve machining accuracy, reduce labor intensity, improve processing work efficiency.Also, easy to operate, labor intensity is small, and processing quality is high, can completely disengage traditional drilling jig tool, realizes Flexible Manufacture.

Description

A kind of undercarriage bearing hole method for fine finishing
Technical field
The present invention relates to undercarriage bearing hole processing technique fields, more particularly to a kind of undercarriage bearing hole Method for fine finishing.
Background technique
For undercarriage bearing hole for installing undercarriage, bearing hole or so concentricity, requirement on machining accuracy are high; It is main at present to be processed using traditional tooling drill jig, first carry out reaming, then finally reamed, guaranteed by drill jig it is left, The concentricity of right side processing, such processing method need a large amount of drilling jig tool, further reduce processing space, and operation is tired Difficulty, large labor intensity, working efficiency is low, and processing quality is poor.
Summary of the invention
In order to solve the above technical problems, the present invention provides the precision that one kind had not only guaranteed undercarriage bearing hole machined, but also energy Labor intensity is effectively reduced, improves processing work efficiency, realizes the undercarriage bearing hole method for fine finishing of Flexible Manufacture.
A kind of undercarriage bearing hole method for fine finishing, comprising the following steps: (1) found out using laser tracker measurement Physical location of the undercarriage bearing hole in aircraft axes;(2) theoretical coordinate value (front and back numerical value and the height of frame bearing hole will be fallen Numerical value) it inputs in lathe, it allows lathe to move to and falls at frame bearing hole theoretical position;(3) knife bar, Cutting tool installation manner are lifted one's head a left side in lose-lose Side, processing left side undercarriage bearing hole;(4) by left side knife bar, cutter change the outfit to lose-lose lift one's head right side, processing right side undercarriage axis Bearing bore;(5) knife bar, cutter are removed, completes manufacturing procedure.
It is had the beneficial effect that by what the technological means present invention obtained, which can It is preferable to improve machining accuracy, labor intensity is reduced, processing work efficiency is improved.Also, easy to operate, labor intensity is small, adds Working medium amount is high, can completely disengage traditional drilling jig tool, realizes Flexible Manufacture.
Specific embodiment
Principles and features of the present invention are described below in conjunction with example, example is served only for explaining invention, not For limiting the scope of the invention.
A kind of undercarriage bearing hole method for fine finishing, comprising the following steps: (1) found out using laser tracker measurement Physical location of the undercarriage bearing hole in aircraft axes;(2) theoretical coordinate value (front and back numerical value and the height of frame bearing hole will be fallen Numerical value) it inputs in lathe, it allows lathe to move to and falls at frame bearing hole theoretical position;(3) knife bar, Cutting tool installation manner are lifted one's head a left side in lose-lose Side, processing left side undercarriage bearing hole;(4) by left side knife bar, cutter change the outfit to lose-lose lift one's head right side, processing right side undercarriage axis Bearing bore;(5) knife bar, cutter are removed, completes manufacturing procedure.It is walked first by lathe and determines hole location in conjunction with laser tracker The front-rear position and high and low position of processing determine the origin of hole location processing, are positioned by lathe and laser tracker, positioning accuracy It is far longer than the positioning accuracy of tooling drill jig, positioning accuracy can reach 0.1mm, and positioning accuracy is high;Since lose-lose is lifted one's head and is processed Knife bar precision-fit, the concentricity of cutter right and left mutually changing reach 0.01mm, are on the other hand processed by way of bore hole, essence Degree reaches 0.01mm, can greatly improve machining accuracy.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it It is interior.
