Description
Technical field
The present invention relates to field of machining, and in particular to large-size machine engine base machining method for finely boring.
Background technology
The serial and other large-size machine engine base both ends end faces of Chang Feng electricity, seam allowance and iron core processing carry out on vertical lathe.
By end face of machine base and inner circle it is rough turn after stay certain surplus, with smart car seam allowance tire position smart car to drawing size, then on milling machine
With seam allowance tire positioning milling, bore footing etc..Its machining process is：Rough turn-smart car-milling, bore footing-plane keyway-drilling.If
The serial and other large-size machine engine base of wind-powered electricity generation uses above-mentioned processing method, and since seam allowance tire positioning accuracy is poor, it is fixed to be easy to cause
Position precision is not allowed, and in addition engine base shape and weight are larger, and especially overall length is too long, and clamping is difficult under engine base upright state, is stablized
Property it is poor, be easy to cause turning stress distribution inequality.Therefore engine base overall dimensional accuracy and bounce precision are not easy to meet product figure
Paper requirement, in addition, easily there is the forward and backward footing face tilt phenomenon of engine base when milling, brill footing.
The content of the invention
To solve the above-mentioned problems, the present invention is provided one kind and is positioned with high-precision tire plate with foot plane and footing hole, smart
It really ensure that engine base center high dimensional accuracy, and ensure that the depth of parallelism of engine base center and foot plane, and production process
In disposable clamping can complete to finish, it is ensured that the concentricity of engine base seam allowance and iron core, ensure that end face of machine base to seam allowance
Bounce requirement, the dimensional accuracy and roughness precision of engine base is greatly improved, improves production efficiency, it is suitable for mass production
Large-size machine engine base machining method for finely boring.
Large-size machine engine base machining method for finely boring of the present invention, comprises the following steps：
The first step, is positioned with foot plane and footing hole with high accuracy positioning tire on boring machine, engine base both ends end is beaten with dial gauge
Face and the first seam allowance, the second seam allowance, the bounce at iron core, are looked for by adjusting positioning fetal position and adjustment fine adjustment screw for engine base
Just, ensure that the first seam allowance of engine base, the second seam allowance, iron core there are enough processing capacities, then positioning tire be fixed on boring table,
At platen press seat footing piece, engine base is compressed；
Second step, is wanted using at boring machine tool special boring the first seam allowance of engine base end face, the first seam allowance and iron core up to product drawing
Size is sought, again clamping lathe tool turning engine base the second seam allowance end face and the second seam allowance, reach the second seam allowance diameter and engine base overall length
Product drawing desired size, the first seam allowance of engine base, the second seam allowance and both ends end face need boring 2 times, boring 1 are only needed at engine base iron core
It is secondary；
3rd step, by clamp loose, engine base, which is hung, goes to next procedure, and when the boring of engine base batch is processed, its positioning tire is non-dismountable,
It need to continue to be fixed on boring table, until can pull down after the completion of batch machining；
4th step, during right boring engine base, only initial workpiece alignment time is slightly long, can be directly mounted at and has fixed before remaining engine base right boring
Tire plate on, survey the bounce at engine base both ends end face, the first seam allowance, the second seam allowance and iron core respectively with dial gauge, pass through fine setting
Screw, which slightly adjusts, can reach right boring centering required precision.
The present invention is positioned with high-precision tire plate with foot plane and footing hole, accurately ensure that the high size essence in engine base center
Degree, and ensure that the depth of parallelism of engine base center and foot plane, and disposable clamping can be completed to finish in production process,
It can ensure the concentricity of engine base seam allowance and iron core, ensure that bounce requirement of the end face of machine base to seam allowance, machine is greatly improved
The dimensional accuracy and roughness precision of seat, improve production efficiency, suitable for mass production.
