With reference to Fig. 3, two shaft gear end faces are enclosed within on the axle 1, are provided with expansion set 3 between two shaft gear endoporus and the axle 1, turn nut and promote pressing plate 4, and expansion set 3 moves axially and locatees and compress two shaft gears 2, and the base with axle is connected through screw with filtering table again.The anchor clamps of Y54 type shaping machine link to each other with transition disc with the trisection screw among Fig. 1; The anchor clamps of YM5132 type shaping machine link to each other with transition disc with quarter screws among Fig. 2; Because the stroke (being the setting height(from bottom) of product to be processed) of two kinds of slotting machine tooling products is different; So in design in the past; When the product in same aperture carried out gear shaping, the anchor clamps of Y54 type shaping machine and YS5132 type shaping machine can not be general, all processing of the minimum needs 20 fourth officer anchor clamps of two shaft gears in 12 kinds of apertures so.These anchor clamps are not only injected capital into many, and the instrument warehouse area of taking is also many.And because the production scene rhythm of production is fast; Two shaft gears are changed frequent, and are when changing two shaft gears, as shown in Figure 4: the beating of end face A that needs to proofread and correct transition disc 5; If the transition disc end face run-out is smaller or equal to 0.01mm; Then can the axle 1 of gear shaping anchor clamps be assembled with transition disc, proofread and correct the location end face B and the centre of gyration Φ D of axle 1 again, two processed shaft gear centers are overlapped with the shaping machine centre of gyration.Frequent replacing two shaft gears have not only increased the auxiliary replacing anchor clamps time and the time of clamping fixture for correcting, and have reduced work efficiency.
Summary of the invention
To the problems referred to above; The purpose of the utility model is to provide a kind of two can be on above-mentioned two kinds of shaping machines general shaft gear gear shaping anchor clamps, not only reduces the input of anchor clamps, reduces the anchor clamps manufacturing cost; And can save the time of on two lathes, changing anchor clamps, to increase work efficiency.
The technical scheme that realizes above-mentioned purpose is following:
Two shaft gear gear shaping anchor clamps; Comprise axle, nut, pressing plate and expansion set with taper hole; Axle is made up of the conical surface section and the thread segment of the terminal pad that connects transition disc, confession two shaft gear suits; Expansion set is enclosed within on the conical surface section; Platen gap is engaged on the conical surface section of axle and pushes down expansion set, and nut is connected with the thread segment of axle, and the terminal pad of axle is provided with first connecting hole, second connecting hole, the 3rd connecting hole, the 4th connecting hole, the 5th connecting hole and the 6th connecting hole; Wherein first connecting hole, second connecting hole, the 3rd connecting hole and the 4th connecting hole are distributed on first group of connecting hole of formation on the same circumference with the form of the same circumference of the quartering, and first connecting hole, the 5th connecting hole and the 6th connecting hole are distributed on second group of connecting hole of formation on the same circumference with the form of the same circumference of trisection.
Adopted such scheme, after being provided with first group of connecting hole and second group of connecting hole on the terminal pad, can fixture application carried out two shaft gears are processed to different lathes; And every secondary anchor clamps have certain aperture range of work, process for two shaft gears in this pore diameter range; Need not to change anchor clamps, total input amount of anchor clamps has reduced aborning, helps reducing the manufacturing cost of anchor clamps; And need not to change anchor clamps, help enhancing productivity.
