Description
Technical field
The present invention relates to the parts fixation technology of digital control processing, particularly a kind of numerical control machining clamping method of elongated shape section bar part.
Background technology
In NC Machining Process, the fixture technology of part is very crucial, and parts fixation mode directly affects processing method, working (machining) efficiency and quality.In the typical structure part of aircraft class, leptosomatic section bar class formation part is the aircraft structure of a quasi-representative.This type of part is owing to having slim-lined construction, yielding feature, and clamping is very difficult.In traditional process, the following installation way of main employing:
Special frock clamp and the installation way of bolt clip plate, this installation way needs this to manufacture special frock clamp to every Element Design, and cost is high, and the cycle is long, uses middle clamping efficiency low, needs to switch clamping in processing.
Automatic hydraulic clamping mode, the frock clamp mode advanced person that this installation way is more special, adopt automatic hydraulic clipping system, realize automatic hydraulic clamping, efficiency is high, is conducive to realizing automation process.But the maximum problem of this mode how to realize being separated of workpiece and clamping clout, and often need the switching carrying out multiple clamping station to solve traditionally, this just has influence on overall processing efficiency.
Summary of the invention
The object of the invention is to the digital control processing quick-clamping method of openly a kind of leptosomatic section bar class aircraft structure, such part automation clamping can be realized, under a clamping station, complete all digital control processing contents, realize the process without the need to Switch of working position.
A numerical control machining clamping method for elongated shape section bar part, is characterized in that comprising following content, 1) section bar part to be processed reserved technique clout bottom it, this technique clout comprises and is separated edge of a knife remainder layer and clamping remainder layer; 2) section bar part is positioned on the vacuum platform of automatic hydraulic fixture, and the width of vacuum platform is less than the bottom width of section bar part, carries out Automatic-clamping by the clamping remainder layer of automatic hydraulic fixture to section bar part; 3) carry out the digital control processing of section bar part, complete the processing of the above all sites in section bar part baseplane; 4) carry out section bar part and clamp being separated of remainder layer, first adopt numerical control disc milling cutter along the separation edge of a knife remainder layer under section bar part baseplane, successively cut from the both sides of workpiece respectively with serpentine track, form workpiece and clamp the thin-walled dowel that clout is serpentine, afterwards, cut from both sides to the thin-walled dowel of serpentine with numerical control disc milling cutter again, form workpiece to be connected with the discrete column of clamping remainder layer, connected by these discrete columns and support workpiece body, 5) by pincers worker, discrete column is connected thoroughly separation.
The invention has the advantages that, above-mentioned compressing method can realize automation clamping process easily, and completes all digital control processings under a clamping station, does not need the switching carrying out clamping, ensure continuity and the working (machining) efficiency of processing, thus realize the digital control processing of automation.Because whole workpiece completes under a clamping station, the harmony of workpiece size improves greatly.Meanwhile, this quick-clamping method has versatility to same kind of parts, need not manufacture and design special tooling, has greatly saved frock manufacturing cost, is convenient to the quick-replaceable realizing product.

Specific embodiment
See accompanying drawing, the present embodiment, for the digital control processing of certain I-section profile part, is set forth in detail to the present invention.
As the section bar part schematic diagram that Fig. 1 is a kind of slender type aircraft structure, material is aluminium alloy.
As shown in Figure 2, first, section bar part 1 to be processed must reserve enough technique clouts bottom it, and this technique clout comprises separation edge of a knife remainder layer 4 and clamping remainder layer 5; Clamping remainder layer 5 thickness is not less than 5mm, for meeting the clamping of automatic hydraulic fixture 3 pairs of workpiece; Be separated edge of a knife remainder layer 4 thickness and be not less than 3mm, for meeting edge of a knife width when workpiece is separated with clamping remainder layer.Before digital control processing, workpiece 1 is positioned on the vacuum platform 2 of automatic hydraulic fixture 3, is adsorbed by vacuum platform 2.The width of vacuum platform 2 is less than the width of workpiece 1.The clamping remainder layer 5 of automatic hydraulic fixture 3 pairs of workpiece 1 carries out Automatic-clamping, completes clamping.After clamping completes, be separated the upper surface of position a little more than automatic hydraulic fixture 3 of edge of a knife remainder layer 4.Then, carry out the digital control processing of workpiece, complete the digital control processing of the above all sites in workpiece baseplane.
Be a kind of numerical control disc milling cutter as shown in Figure 3, milling when being separated with clamping remainder layer 5 for workpiece, its thickness approximates the thickness being separated edge of a knife remainder layer 4.
After workpiece 1 digital control processing completes, carry out workpiece with clamping remainder layer 5 be separated milling.
As shown in Fig. 4, Fig. 7, first adopt numerical control disc milling cutter 6 along the separation edge of a knife remainder layer 4 under section bar part baseplane, successively cut from outside to inside from the both sides of workpiece respectively with serpentine track, form workpiece 1 to be connected with the thin-walled dowel 7 of clamping remainder layer 5 in serpentine, remainder realizes being separated.The wall thickness of the thin-walled dowel 7 of serpentine is about 1mm, highly about 3mm, is the distribution of serpentine even rule at workpiece bottom, and between workpiece 1 and clamping remainder layer 5, its scope coating workpieces substantially elongated logical wide, for connecting workpiece.The radius of curvature of the thin-walled dowel 7 of serpentine is greater than the radius of numerical control disc milling cutter 6.
Afterwards, use numerical control disc milling cutter 6 successively to cut from both sides to the thin-walled dowel 7 of " S " again, the final workpiece 1 that formed is connected 8 with the discrete column of clamping remainder layer 5, and its sectional dimension is about 1mm × 1mm, roughly be uniformly distributed in workpiece bottom, as shown in Figure 6, Figure 7.
So far, the Separation of Cutting on Digit Control Machine Tool terminates.Finally, by pincers worker, discrete column is connected thoroughly separation, complete the digital control processing of section bar part.
