Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
nullA kind of blade milling tenon tooth fixture as shown in Fig. 1 to Fig. 6,In order to clamp blade 1,This fixture is fixed on the machine tooling platform of processing blade tenon tooth,Including base plate 2,The leaf top clamping device on leaf top, location it is provided with on base plate 2,It is additionally provided with the blade root clamping device of location blade root 10,Described blade root clamping device includes that this cantilever shelf 5 of cantilever shelf 5(with shelf top 8 is by two ferrum seat supports,Shelf part is suspended in the air),The oblique slide 18 that upper surface tilts and is positioned at cantilever shelf 5 lower end it is fixed with on described base plate 2,The locating piece 17 that longitudinal register leaf is takeed on is included in the middle part of described oblique slide 18,Described locating piece 17 both sides are respectively arranged with the first angled-lift splits 15 and the second angled-lift splits 14 of location tenon tooth,Described first angled-lift splits 15 and the second angled-lift splits 14 can slide along oblique slide 18 upper surface and fixing.
Further, described base plate 2 tilts an angle, and this angle can make to clamp the angle that blade 1 is tenon tooth centrage 20 holding level.
After using this structure, oblique slide 18 it is provided with on base plate 2, tiltedly slide 18 and the first angled-lift splits 15 and the second angled-lift splits 14 with the use of, elimination tenon tooth bottom, the position hovering adjusting angled-lift splits reaches sturdy supporting, oblique slide 18 arranges spacing locating piece 17 at blade 1 two ends longitudinal direction and carries out longitudinal register, it is achieved dimensional uniformity and the site symmetry requirement adding man-hour is exchanged in upset.This holder is stable, preferable rigidity can be kept, meet the clamping demand of big cutting force, plus having accurate bottom surface adjustable positioning and longitudinal strong fix, it is ensured that the reliability of polish, when making processing, mechanical vibration are eliminated improvement significantly simultaneously, ensure that build roughness controls the requirement at Ra1.6um, machined surface profile degree excursion also ensures the design requirement at 0.04mm, remaining relative dimensions, the biggest improvement of symmetry status.In the prior art, the base plate 2 of blade fixture is usually level, processing blade root 10 when, the profile of tooth centrage of blade root 10 is to tilt, so tenon tooth is to tilt, it is the highest that this will cause adding man-hour tenon tooth stability under loading degree, may produce the phenomenon laterally channeled bit.In the present invention, so that tenon tooth centrage 20 is in level processing, therefore base plate 2 is set to tilt an angle, and tiltedly slide 18 with the use of, further such that it is stable to add man-hour uniform force, effective elimination laterally channels bit trend.
Preferably, interior big outer little chute 16 it is provided with on described angled-lift splits, described base plate is provided with adjustment seat 6 near oblique slide 18, and described adjustment seat 6 is provided with the adjusting rod of regulation angled-lift splits, and described adjusting rod end is identical with chute 16 shape and arranges with chute 16 coupling.As shown in Figure 1, in adjustment seat 6, adjusting rod is set, adjusting rod end and chute 16 match setting, that is, direct regulation adjusting knob 13 just can regulate angled-lift splits and move on oblique slide 18, regulation angled-lift splits, in order to realize the intact laminating supporting of tenon tooth bottom surface, reduces the error that vibration brings to greatest extent.Owing to the width of blade 1 leaf shoulder is different, as shown in Figure 6, the tenon tooth of blade 1 is symmetrically arranged, but leaf shoulder is divided into narrow leaf shoulder 11 and wide leaf shoulder 12, second angled-lift splits 14 is divided into the A(the highest) and B(the most relatively low) two types, when processing wide leaf shoulder 12 respectively and narrow leaf takes on 11, use angled-lift splits B and angled-lift splits A that leaf shoulder is supported respectively.
Further, described base plate 2 is respectively arranged with limiting plate 21 near the first angled-lift splits 15 and the second angled-lift splits 14.This limiting plate 21 prevents angled-lift splits from vertically moving, and also plays the function of guiding simultaneously.
It is preferred that described leaf top clamping device is one to have top tailstock 3.Owing to tailstock 3 has top, this top connection has adjusting means, in that context it may be convenient to is finely adjusted and holds out against vane tip.
It is preferred that described cantilever shelf 5 side is additionally provided with first screw 19 of location blade root 10.It is provided with on cantilever shelf 5 and connects the top of adjusting means, it is also possible to being adjusted the clamping of blade root 10 easily, cantilever shelf 5 side arranges the first screw 19 can carry out located lateral to blade root 10.
It is preferred that described cantilever shelf 5 front and back end is respectively arranged with to compress the pressing plate 4 of blade root 10.The leaf shoulder of described pressing plate 4 and blade root 10 contact and compress leaf shoulder, further ensure that process blade 1 when blade 1 steady, will not vibrate, it is ensured that the precision of processing.
It is preferred that arrange the second screw 7 longitudinally holding out against blade root 10 on described cantilever shelf 5, the gradient of described oblique slide 18 is 10 °.In real work, find the gradient of oblique slide 18 be set to 10 ° relatively reasonable.When the leaf of blade root 10 is takeed on and abutted on locating piece 17 when, tighten the second screw 7 so that blade root 10 longitudinal register accurately consolidates, and will not shake.
Oblique slide 18 and angled-lift splits matched together on this clamp bottom board 2 realize the intact laminating supporting of tenon tooth bottom surface, reduce the error that vibration brings to greatest extent, consider that the position of blade 1 milling build is by mean of the angled design of clamp bottom board 2 and makes tenon tooth centrage 20 lift into level simultaneously, the purpose arranging angle is so that tenon tooth vertical stress up and down is in same level, the both sides of toothed surface circular arc also exist together uniform stressed on horizontal level, then utilize profile milling cutter to tenon tooth machine-shaping.
Tailstock 3 top and on cantilever shelf 5 shelf top 8 above realizes longitudinally holding out against blade 1 two ends, and it is provided with fine setting, when leaf shoulder portion reclines locating piece 17, then lock the second screw 7, remake the top fine setting in two ends and pin blade 1 lengthwise position, it is then carried out the first angled-lift splits 15 and fine setting of the second angled-lift splits 14, wherein the second angled-lift splits 14 includes A, (A is higher for B two angled-lift splits, B is shorter), (narrow leaf takes on 11 corresponding A and the corresponding B of wide leaf shoulder 12) is used when blade 1 adds exchange in man-hour as turn-over, owing to locating piece 17 is as fixing spacing, location makes to overturn symmetry and the dimensional uniformity of energy intact holding two heel teeth when processing second profile of tooth, eliminate the cumbersome work repeatedly adjusting centering.
In terms of compression, realize the stationary state that four sides surrounds, not only fasten but also reliable, the trip bolt on pressing plate 4 and pressing plate 4 form main hold down gag, it is ensured that have powerful pressure force, the second screw 7 realize directly compressing, anti-longitudinal leap ability when strengthening cutting.Cantilever shelf 5 is in order to support the shelf top 8 of blade root 10 termination, it is ensured that the concordance that center, two ends is high, and the combination of each design of part is coupled with bolt location by straight pin 9.
