Abstract
The present invention discloses a kind of web notch arrangement processing method, including retaining false boss above dimensioned notch in place, the false boss exceeds notch boundary 0.5mm or more on the boundary in width of rebate direction, until the false boss is removed after other features of web part are all processed in place.Using processing method of the invention, it can stablize and numerical control processing is carried out to notch arrangement, only stay the residual of 0.05mm in notch edges, pincers worker need to only do the work of approximate polishing, and polishing amount is small, be not easy to be hit by a bullet knife in pincers worker process.
Description
Technical field
The present invention relates to metal cutting process fields, in particular to aerospace component numerical control processing field, and in particular to one
Kind web notch arrangement processing method.
Background technique
Aerospace component because assembly demand usually there is the web structure with notch, however, this web structure into
When row numerical control processing, in the endpoint location (as shown in Figure 1) of notch, easily causes and play knife broaching tool, so that part quality be caused to ask
Topic.
The traditional numeric-control method of such web structure is as shown in Fig. 2, connect 2 union piece webs 1 and technique using sheet
Boss 3 compresses false boss in processing, to guarantee the rigidity with notch arrangement in processing, passes through pincers worker later for work
The removal of skill boss, and in place by edge polishing.But processing the drawbacks of there are three aspects in this way: first, remove boss can generate compared with
More bench work amounts, influences the processing efficiency of part；Second, even now ensure that the rigidity of part in numeric control, but
But difficulty pincers worker has been transmitted to, web rigidity is still poor when pincers worker polishing, and when polishing easily plays knife, to pincers worker level
It is required that very high；Third, end face guarantee that size and geometric tolerance, precision are difficult to ensure by pincers worker.In actual production, due to pincers
The case for making mistakes when work polishing web notch and causing part overproof or even scrapping happens occasionally.
Summary of the invention
The purpose of the present invention aims to solve the problem that traditional is processed in the presence of trough of belt food plate method by setting boss
Problem provides a kind of web notch arrangement processing method.Processing method of the invention can be in NC Machining Process by trough of belt
Food plate complete stability is processed in place, is neither generated in process and is played knife broaching tool, and pincers worker polishing amount is again small.
Above-mentioned purpose of the invention is realized using following technical scheme:
A kind of web notch arrangement processing method, including retaining false boss, the work above dimensioned notch in place
Skill boss exceeds notch boundary 0.5mm or more on the boundary in width of rebate direction, until other features of web part are all processed
After in place, the false boss is removed.
It is wherein described that false boss removal is thin including first milling false boss, until false boss and notch are in depth of rebate
Until effective connection depth in direction is 1 ~ 2mm, after milling thin false boss, feed speed is reduced to original one third,
False boss milling is disconnected, close to last cutter shaft of part web surface to cutter lifting 0.2mm or more.
It is to be processed by axial first hierarchy when wherein milling thin false boss.
Using web notch arrangement processing method of the present invention, it can stablize and numerical control processing is carried out to notch arrangement,
The residual of 0.05mm is only stayed in notch edges, pincers worker need to only do the work of approximate polishing, and polishing amount is small, is not easy during pincers worker
Play knife.Therefore the present invention compared to traditional boss overlapping mode the beneficial effect is that:
1, band notch processing stability is improved, the bullet knife broaching tool being also easy to produce when eliminating with notch finishing；
2, without breaking process boss under pincers worker, the workload and quality risk when pincers worker polishing are reduced.
Detailed description of the invention
Fig. 1 schematically illustrates the easy notch endpoint location for occurring to play knife broaching tool on trough of belt food plate.
Fig. 2 schematically illustrates the boss connection type in the conventional method by setting boss to process trough of belt food plate.
Fig. 3 schematically illustrates the setting of the boss in the method for the present invention and removing method.
Specific embodiment
For a clearer understanding of the present invention, with reference to the accompanying drawings and embodiments, the present invention is carried out further specifically
It is bright.
The present invention provides a kind of web notch arrangement processing method, including retaining work above dimensioned notch in place
Skill boss, the false boss width of rebate direction boundary exceed notch boundary 0.5mm or more, until web part other
All after processing in place, the false boss is removed for feature.
It is wherein described that false boss removal is thin (that is, false boss partial volume is gone including first milling false boss
Except), to false boss and notch until effective connection depth in depth of rebate direction is 1 ~ 2mm, after milling thin false boss,
Feed speed is reduced to original one third, false boss is milled it is disconnected, close to last cutter shaft of part web surface to cutter lifting
0.2mm or more.
It is to be processed by axial first hierarchy when wherein milling thin false boss.
It is illustrated by taking the trough of belt food plate of 7050-T7451 aluminum alloy part as shown in Figure 3 as an example below:
The part is two-sided part, web thickness 1.5mm, width of rebate 30mm, depth of rebate 50mm.
Firstly, when processing the first face of part, in place by notch dimensioned.
Then when processing the second face of part, false boss as shown in Figure 3, width 32mm, depth 40mm, first by part are stayed
Other feature machinings are in place (as shown in left part in Fig. 3).
It is as thin as on depth of rebate direction false boss milling to retain 9mm, axial cutter lifting from web edge later
0.03mm, since in notch endpoint location (referring to Fig. 1), there are chamferings, false boss and notch are in depth of rebate side at this time
To actually active connection depth be 1mm (as shown in middle section in Fig. 3).It is by axial preferential when wherein milling thin false boss
Layering processing.
After milling thin false boss, feed speed is reduced to original one third, last knife will break under false boss,
Axial cutter lifting 0.2mm (as shown in right part in Fig. 3).
The residual of notch edges is polished in pincers worker process and is removed.
Claims (3)
- It is described including retaining false boss above dimensioned notch in place 1. a kind of web notch arrangement processing method False boss exceeds notch boundary 0.5mm or more on the boundary in width of rebate direction, until other features of web part all add Work in place after, the false boss is removed.
- 2. processing method described in accordance with the claim 1, wherein it is described that false boss removal is thin including first milling false boss, To false boss and notch until effective connection depth in depth of rebate direction is 1 ~ 2mm, after milling thin false boss, by work The milling of skill boss is disconnected, close to last cutter shaft of part web surface to cutter lifting 0.2mm or more.
- 3. processing method described in accordance with the claim 1 is to process when wherein milling thin false boss by axial first hierarchy.
