Description
Technical field
The present invention relates to the machining process of large-scale support, relate in particular to a kind of support machining method for finely boring and support right boring thereof.
Background technology
Usually support end face and interior circle processing are carried out on vertical lathe; with the support end face and in circle stay certain surplus after rough turn; locate finish turning to the figure paper size with finish turning seam tire then; on milling machine, mill then with seam tire location; bore footing etc.; its concrete processing process is: rough turn-finish turning-as to mill; bore footing-plane keyway-boring; if wind-powered electricity generation series support and other large-scale support adopt said method processing; because seam tire positioning accuracy is relatively poor; cause positioning accuracy inaccurate easily; support profile and weight are bigger in addition; especially length overall is oversize, clamping difficulty, less stable under the support upright state; cause turning stress distribution inequality easily; therefore the support overall dimensional accuracy and the precision of beating are difficult for satisfying the product drawing requirement, in addition, mill; before being prone to support when boring footing; back footing face tilt phenomenon.
Summary of the invention
The purpose of this invention is to provide a kind of processing method that can satisfy large-scale support dimensional accuracy and Geometrical Tolerance Principle.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of support machining method for finely boring, and these support machining method for finely boring concrete steps are as follows:
A, on vertical lathe vertical clamping, adopt chuck to clamp support A place, rough turn support seam (6) and place unshakable in one's determination behind the centering, seam (6) end face stays allowance, seam (6) diameter stays allowance, the diameter of locating unshakable in one's determination stays allowance; Support upset back clamping clamps support cylindrical B place with chuck, and the empty cutter of turning place is to the product drawing size behind the centering, locate by given dimensional tolerance finish turning seam (7), and guarantee to reserve allowance, being used to mill, locating when boring footing and use, seam (7) is located end face and is reserved allowance;
B, on the numerical control drilling-milling bed with the vertical installation of support, and locate with seam location tire location support seam (7), adopt hydraulic platen to compress support B end, with disc type milling cutter milling foot plane and with spiral bit drilling footing hole;
C, on boring machine, locate with foot plane and footing hole with the hi-Fix tire, beat beating of support two ends end face and seam (6), seam (7), place unshakable in one's determination with dial gauge, by adjusting the fetal position, location and adjusting fine adjustment screw is the support centering, guarantee that support seam (6), seam (7), iron core have enough processing capacities, to locate tire then is fixed on the boring table, with platen press seat footing piece place, support is compressed;
D, special-purpose lathe tool boring support seam (6) end face of employing boring machine, seam (6) and place unshakable in one's determination reach the product drawing size; Again clamping lathe tool turning support seam (7) end face and seam (7) make seam 2 diameters and support always reach the product drawing size; Support seam (6), seam (7) and two ends end face need boring 2 times, and support place unshakable in one's determination only needs boring 1 time;
E, with clamp loose, support hangs and goes to next procedure.
The another kind of improved technical scheme of the present invention is: a kind of support right boring according to the processing of support machining method for finely boring comprises boring machine, boring machine cutter head, fine adjustment screw, location tire and boring table.
This support comprises foot plane, seam, iron core, retaining platform and empty cutter place.
The advantage of support machining method for finely boring of the present invention and support right boring thereof is:
1. wind-powered electricity generation series and other large scale computer seats adopt horizontal clamping with respect to vertical clamping, and are more reasonable, and support stability improves much during processing, is easier to guarantee the stability and the accuracy of support dimensional accuracy and form and position tolerance.
2. locate with foot plane and footing hole with high accuracy tire plate, guaranteed support center high dimensional accuracy accurately, and guaranteed the depth of parallelism of support center and foot plane.
3. disposable clamping can be finished fine finishining, can guarantee support seam and concentricity unshakable in one's determination, has guaranteed the beat requirement of support end face to seam, has significantly improved the dimensional accuracy and the roughness precision of support.
4. by this method, can save the preceding centering time of right boring significantly, especially be fit to produce in batches.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the support right boring structural representation of support machining method for finely boring of the present invention and support right boring thereof;
Fig. 2 is the stand structure schematic diagram of support machining method for finely boring of the present invention and support right boring thereof.
The specific embodiment
As shown in Figure 1 and Figure 2, the support right boring comprises boring machine 1, boring machine cutter head 2, fine adjustment screw 3, location tire 4 and boring table 5; Wherein support partly comprises seam 6, seam 7, iron core 8, foot plane 9, retaining platform 10 and empty cutter place 11, and the support machining method for finely boring concrete steps of this support machining method for finely boring and support right boring thereof are:
1. support is pressed the vertical clamping of traditional approach on vertical lathe, promptly adopt chuck to clamp support A place, rough turn support seam (6) and place unshakable in one's determination behind the centering, seam (6) end face stays 1mm allowance, seam (6) diameter stays 2mm allowance, and place unshakable in one's determination diameter stays 1.5mm allowance (promptly reserving 1 time allowance to the product drawing size of right boring); Support upset back clamping, promptly clamp support cylindrical B place with chuck, the empty cutter of turning place is to the product drawing size behind the centering, locate by given dimensional tolerance finish turning seam (7), and 2mm allowance is reserved in assurance, be used to mill, locate when boring footing and use, seam (7) is located end face and is reserved 1mm allowance.
