Abstract
A kind of process for machining of curve surface work pieces, it is characterized in that: in semifinishing and fine finishining stage, by being installed in the special-purpose rigid support and the dial gauge that is contained on the rigid support free end on the knife rest, set up the workpiece to be machined profile that is installed on the workbench and be installed in getting in touch between the inspection template on side tool post etc., in the process, by cutter amount under the artificial adjustment, make between dial gauge table point and model outer contour or the face gap such as maintenance substantially or etc. the magnitude of interference.This technology is to single-piece.The processing of small lot curve surface work pieces, can reach the processing duration short, expense is low, the measured effect of profile matter, and can on multiple lathe, adopt.
Description
The invention belongs to the process for machining of mechanical processing industry curve surface work pieces.
The processing of known curve surface work pieces (comprising that arc surface, inclined-plane and song, inclined-plane intersect workpiece), the particularly processing of some large surface workpieces and mould, general output is all little, the normal pattern processing technology that adopts, but pattern manufacturing expense height, manufacture difficulty is big, and the fabrication and installation pattern time is long, all can not reach the processing effect that the duration is short, expense is low to small lot or single-piece work.And the manual processing of traditional experience, to skilled worker's requirement height, the time is long, and quality is difficult for guaranteeing.
In view of the problem that above-mentioned prior art exists, task of the present invention provides a kind of single and mini-batch production production that is suitable for, and the curve surface work pieces that can promote the use of on multiple lathe and the process for machining of mould.
The technical characterictic that claim 1 provides has solved above-mentioned task.According to " technology using pointer to track templet for processing workpieces with curved surface " of the present invention, at first, press on the workpiece institute's setting-out roughing to basic forming, then, by be installed in the rigid support on the knife rest and be installed in dial gauge on the support free end set up the workpiece to be machined profile and be installed in side tool post or lathe bed etc. on inspection template between get in touch, when cutter after the starting point of workpiece with form surface is to good cutter, the cantilever by regulating support and collude the short or relative position by mobile model of brachium etc. with dial gauge table point refer to the corresponding model of the starting point of workpiece with form surface on same point.Afterwards, just can begin to carry out the semifinishing and the fine finishining of workpiece with form surface.Add man-hour, stamp self-acting feed to keep certain amount of feeding, simultaneously, constantly adjust down the cutter amount by hand control, make in process between dial gauge table point and the model outer contour gap such as maintenance substantially or etc. the magnitude of interference, until whole work-piece profile completion of processing.
When small lot ground processing large surface workpiece or mould, adopt using pointer to track templet technology of the present invention to process, need not make special frocks such as pattern, but utilize the inspection template of workpiece to make to follow the tracks of model, thereby its frock making is simple, and manufacturing cost only is about 1% of a pattern manufacturing expense.The Installation and Debugging of frock also are easier to, and need not dismantle machine tool component when being installed, so do not influence the processing of other workpiece.In addition, this technology is grasped easily, and the workpiece with form surface quality that processes is easy to guarantee, and can be at car, mill, adopt on the multiple lathe such as plane.
One embodiment of the present of invention have been described among the figure.
Fig. 1 is the scheme of installation of its frock of technology using pointer to track templet for processing of the present invention on metal-planing machine.
According to process for machining of the present invention, the whole process of curve surface work pieces can be divided into roughing, semifinishing and fine finishining three phases substantially.Phase I, be roughing.Be about to workpiece (8) clamping and go up (as shown in Figure 1), process the curve form of workpiece (8) by institute's setting-out on the workpiece, and stay the allowance about 4MM at workbench (7).Second stage is semifinishing.In first being processed, at first to carry out the installation and the debugging of special tooling of the present invention and equipment.Promptly as shown in Figure 1, an end of rigid support (2) is installed on the knife rest (6), the other end that dial gauge (3) is installed then is free end.By follow rest (6), find out the horizontal datum of the inspection template (4) that is installed on the side tool post (5), workpiece (8) datum level or line and model (4) datum level or line are parallel to each other.Secondly, carry out tool setting and check and correction.Soon (the height point that the tool setting starting point is selected in workpiece with form surface is intersection point A place to the point of a knife of cutter (9) in workpiece (8) profile intersection point A place's tool setting, can avoid misoperation or feed error to cause knife), vertical cutter down is to allowance 1MM place, dial gauge (3) is then gone up with corresponding some A ' of A point at model (4) and is located check and correction, promptly by mobile side tool post (5), make between dial gauge (3) table point and model (4) outer contour at an A that " gap of locating is workpiece (a 8) allowance size (being 1MM); after tool setting and check and correction finish, just can stamp horizontal self-acting feed and begin semifinishing.In the process, according to feed size and work radian.The gradient size is adjusted vertical cutter amount down (vertical feed is hand control), the gap between dial gauge (3) table point and the model (4) is remained between the 0.5MM to 1MM, up to whole work-piece profile completion of processing.Phase III, be fine finishining.During fine finishining, its tool setting, proofreading method are identical with semifinishing, vertical cutter down is to compact dimensions at workpiece (8) profile intersection point A place, and dial gauge (3) is gone up with corresponding some A ' of some A at model (4) and located to transfer to magnitude of interference 0.1MM to 0.2MM between table point and the model.Turn dial gauge (3) watchcase makes dial gauge pointer zero set (so that the operator observes), in the process, by the vertical feed of artificial adjustment metal-planing machine, pointer is remained in zero-bit three lattice.
According to above operation sequence and requirement, shaping workpiece and inspection template error can be controlled in the 0.1MM, and surface smoothness can reach
4.
About the selection of tool type,, can adopt most advanced and sophisticated cutter usually for semifinishing; Fine finishining can be adopted bull nose tool, and knife tool arc is neglected minimum work circular arc greatly and decided.
In addition, for the lathe of some no side tool posts, when carrying out the frock debugging, the relative position of level or vertically mobile inspection template (4) relatively more difficult, so can consider rigid support (2) is made scalability, so that regulate the cantilever of rigid support (2) and collude brachium short.
Claims (3)
