Description
Technical field
The present invention relates to a kind of using bent plate processing thin wall component aluminium arm processing method and tooling, belongs to mechanical technique
Field.
Background technique
Mechanical arm is the key part of machining center cutter-exchange mechanism, and part is thin-walled parts, and surrounding all has in processing
Hold, is processed on horizontal Machining centers, clamping problem is very crucial.
Horizontal Machining centers, workbench can complete 360 degree rotation, workpieces processing peripheral contents, and common installation way is
Workpiece is placed on work top, clamping force is directed toward work top, and when encountering thin wall component, this installation way is not easy
Processing, workpiece are easy to produce deformation, displacement, cause part defective products, processing efficiency is low, and stability is poor.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of utilization bent plate processing thin wall component aluminium arm processing
Method and tooling.
A kind of tooling using bent plate processing thin wall component aluminium arm, including tooling support, bolt, substrate, via hole, the
One pressing plate, the first top, the first positioning pin, the first workpiece to be processed, the second workpiece to be processed, second top, the second positioning pin
And second pressing plate, substrate are connect by bolt with tooling support, substrate be distributed with the first pressing plate, first top, the first positioning pin,
Second top, the second positioning pin and the second pressing plate, the first positioning pin, the second positioning pin position the first workpiece to be processed, respectively
Two workpieces to be processed, the first pressing plate, the second pressing plate, which are pushed down, fixes the first workpiece to be processed, the second workpiece to be processed, first top,
Second top positions the first workpiece to be processed, the second workpiece to be processed respectively.Thin-wall part part is completed using bent plate design tooling
The processing of aluminium arm improves processing efficiency and stability.
It is a kind of to process thin wall component aluminium arm processing method using bent plate, contain following steps；
Centering is straightened in step 1, substrate, guarantees in 0.01mm with inner, and the first pressing plate and the second pressing plate are loaded first to be processed
Workpiece and the second workpiece to be processed bore, attack 4-M8 thread Pilot hole, and boring Φ 45H7 stays right boring amount 1mm in hole, as second of clamping
Technological datum；
Step 2 screws in 4-M8 on the first workpiece to be processed and the second workpiece to be processed with 4-M8 screw behind plate
Threaded hole is fixed on the first workpiece to be processed and the second workpiece to be processed on substrate instead of the first pressing plate and the second pressing plate, solution
Certainly the first pressing plate and the second pressing plate influence feed path problem, stay right boring amount 1mm with the hole Φ 45H7, as clamping process benchmark,
It determines that X/Y coordinate, plate determine Z coordinate, determines the first workpiece to be processed and the second workpiece to be processed correspondingly-sized；
Step 3, by the first workpiece to be processed and the second workpiece to be processed flip horizontal 180 degree, in second of clamping plus
On the basis of the hole Φ 45H7 of work, determines that X/Y coordinate, plate determine Z coordinate and processing corresponding size, complete all the elements processing.
The comparison of the present invention and the prior art: initial design technique is with the small table top of 30*25*3 at main view lower part two
As datum level, be placed on above cushion block, pressing plate push down above two at the small table top of 30*25*3, clamping power be directed toward work top,
Such clamping method can only have two points stress, and workpiece location difficulty, and pressure folder portion position is Chong Die with machining path, be not easy away
Knife, and workpiece is easy to happen displacement in process, and causes that Φ 25H7 and the aperture Φ 17H7 is easily caused to deform.So this
Fixture scheme is denied.39 size two sides of workpiece has already passed through roughing, every face allowance 2mm, the present invention by 39 size of workpiece its
Middle to be attached on bent plate on one side, in this way, datum level area increases, accurate positioning is stablized after stress, by overturning workpiece several times, just
It can complete work pieces process.Using bent plate, workpiece two sides is attached on bent plate, in this way, datum level area increases, accurate positioning, by
It is not easy to be displaced after power, tool hand adds 0 degree of man-hour requirement, 90 degree and 270 degree of three faces to process at one time and guarantee the corresponding ruler in side
The mutual alignment relation of very little coaxial 0.01MM and critical size.
The invention has the advantages that the key part of machining center cutter-exchange mechanism, part size is the thin of 569.8*120*39
Wall part is completed the processing of thin-wall part part aluminium arm using bent plate design tooling, improves processing efficiency and stability.

Two technique navel faces on the upside of the face 39-0.10.
Step 1, bore, attack 4-M8 thread Pilot hole at；
Right boring amount 1mm is stayed in step 2, the hole boring Φ 45H7, as second of clamping process benchmark；
Workpiece disposing way such as first time clamping, but do not have to pressing plate pressure folder workpiece, and with 4-M8 screw after plate
Face screws in the 4-M8 threaded hole on workpiece, is fixed on workpiece on bent plate, so solves the problems, such as that pressing plate influences feed path, the
Right boring amount 1mm is stayed in the hole Φ 45H7 processed in clamped one time, as second of clamping process benchmark, determines X/Y coordinate, plate
Determine Z coordinate.
Step 3, processing 39 sizes (size of 26+13 in Fig. 7) are above and including brill, the hole boring 2- Φ 17H7,2- Φ 8H7
The all the elements such as hole, the hole Φ 45H7,2- Φ 95H7 semicircle orifice；
Step 4, processing 569.8 size, two side direction content, the hole 2- Φ 17H7,23 hole 2- Φ, the hole 2- Φ 25H7 etc. are all
Content.
By workpiece flip horizontal 180 degree after the processing of second secondary card, in 39-0.10 size (size of 26+13 in Fig. 7)
It on the basis of face, is attached on bent plate, equally screws in the 4-M8 threaded hole on workpiece behind plate with 4-M8 screw, fix workpiece
The processing content on bent plate；
Step 5, on the basis of the hole Φ 45H7 processed in second of clamping, determine that X/Y coordinate, plate determine Z coordinate.
Step 6, processing 39 sizes (size of 26+13 in Fig. 7) are below and the hole Φ 65H7, completion all the elements are processed.
It summarizes, by above-mentioned process, completes whole processing contents of arm, moreover, by examining, all sizes are complete
Meeting drawing requirement entirely, fixture scheme is feasible, solves the processing difficulties of this thin-wall part, it avoids because clamping dynamics is insufficient,
Position inaccurate, clamping pressure project ring feed path the problems such as bring inefficiency, the unstable result of processing quality.
As described above, embodiments of the present invention are described in detail, as long as but essentially without this hair of disengaging
Bright inventive point and effect can have many deformations, this will be readily apparent to persons skilled in the art.Therefore, this
The variation of sample is also integrally incorporated within protection scope of the present invention.
