Summary of the invention
The object of the invention is: the cutting-off method proposing a kind of aluminium alloy case type structures part technique pressing table of improvement, to simplify operation, shorten the process-cycle; Meanwhile, avoid secondary clamping centering, reduce correct error, ensure crudy.
Technical scheme of the present invention is: the cutting-off method of aluminium alloy case type structures part technique pressing table, and respectively have a technique pressing table 2 at the two ends, left and right of processed case type structures part 1, it is characterized in that, the step of Cutting process pressing table 2 is as follows:
1, cutting groove 3 is processed: adopt Digit Control Machine Tool at the upper surface of the technique pressing table 2 at case type structures part 1 two ends each Milling Machining cutting groove 3, the box wall outer surface of the case type structures part 1 be connected with technique pressing table 2 is the inner side cell wall of cutting groove 3, the groove width of cutting groove 3 is 11mm ~ 15mm, the thickness of groove bottom of cutting groove 3 is 0.15mm ~ 0.3mm, cutting groove 3 through technique pressing table 2 front and rear surfaces;
2, remove bottom technique cutting groove and connect: the bottom of the technique cutting groove 3 of the direct sliding trackle 0.15mm ~ 0.3mm of pincers worker flat chisel, case type structures part 1 is taken off from platen;
3, deburring: deburring operation is carried out in pincers worker, completes the cut-out of technique pressing table 2.
Advantage of the present invention is: the cutting-off method proposing a kind of aluminium alloy case type structures part technique pressing table of improvement, simplifies operation, shorten the process-cycle; Meanwhile, avoid secondary clamping centering, reduce correct error, ensure that crudy.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of case type structures part 1 on aircraft.
Fig. 2 is the structural representation before the technique pressing table 2 at current case type structures part 1 two ends does not cut off.
Fig. 3 is the structural representation process cutting groove 3 on the technique pressing table 2 at case type structures part 1 two ends after.In figure, in paper, direction is rear, and the outer direction of paper is front, and direction is constant up and down.
Detailed description of the invention
Below the present invention is described in further details.See Fig. 2,3, the cutting-off method of aluminium alloy case type structures part technique pressing table, respectively have a technique pressing table 2 at the two ends, left and right of processed case type structures part 1, it is characterized in that, the step of Cutting process pressing table 2 is as follows:
1, cutting groove 3 is processed: adopt Digit Control Machine Tool at the upper surface of the technique pressing table 2 at case type structures part 1 two ends each Milling Machining cutting groove 3, the box wall outer surface of the case type structures part 1 be connected with technique pressing table 2 is the inner side cell wall of cutting groove 3, the groove width of cutting groove 3 is 11mm ~ 15mm, the thickness of groove bottom of cutting groove 3 is 0.15mm ~ 0.3mm, cutting groove 3 through technique pressing table 2 front and rear surfaces;
2, remove bottom technique cutting groove and connect: the bottom of the technique cutting groove 3 of the direct sliding trackle 0.15mm ~ 0.3mm of pincers worker flat chisel, case type structures part 1 is taken off from platen;
3, deburring: deburring operation is carried out in pincers worker, completes the cut-out of technique pressing table 2.
The inventive method, after being worked into state shown in Fig. 2, not needing to dismantle part to be processed, directly processes cutting groove 3, thus avoid secondary clamping centering, reduce correct error, what eliminate the box wall outer surface of case type structures part 1 connects tool marks, ensure that crudy.In addition, eliminate manual miller sequence, shorten the process-cycle, improve working (machining) efficiency.
