The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.This is preferred embodiment of the present utility model.
See Fig. 1, Fig. 2, shown in Figure 3, a kind of modular tool interface of stock-removing machine, the taper hole 1 and the axis of cone 2 that comprise taper fit, and the locking device 3 that radially runs through the described taper hole 1 and the axis of cone 2, described taper hole 1 hole wall radially offers pin-and-hole 11, the position of the described axis of cone 2 respective pin hole 11 radially offers connecting hole 21, described locking device 3 runs through described pin-and-hole 11 and connecting hole 21, described locking device 3 comprises a turnbuckle 31, with the taper pin 32 that is bolted in described turnbuckle 31 ends, described taper pin 32 surfaces are taper surface, taper pin 32 axle center axially offer the internal thread hole that cooperates with described turnbuckle 31, the taper surface of described taper pin 32 offers along the gathering sill 321 of taper pin 32 axial distribution, and described pin-and-hole 11 inwalls convex with the guide pad 12 that is complementary with described gathering sill 321; Described taper pin 32 stretches into described connecting hole 21 during locking.
See illustrated in figures 1 and 2ly, the utility model is applied to instrument assembling, and instrument is fixed in the axis of cone 2 to be held greatly, and taper hole 1 is opened in the machine tool chief axis output.During assembly tool, the described axis of cone 2 is inserted in described taper hole 1, makes described connecting hole 21 be positioned at same axis, turnbuckle 31 is passed pin-and-hole 11 and connecting hole 21 with described pin-and-hole 11, thereby run through the axis of cone 2 and taper hole 1, taper pin again is spirally connected in described turnbuckle 31 ends; Turn turnbuckle 31, taper pin moves axially along turnbuckle 31 and stretches into the connecting hole 21 of the axis of cone 2; Because the taper pin surface is a taper surface, the taper pin diameter of section that stretches into connecting hole 21 becomes big gradually, the taper surface contact position that makes described connecting hole 21 and described taper pin 32 is under the radial thrust effect of taper surface, promoting the axis of cone 2 edge N as shown in Figure 1 in taper hole 1 makes the axis of cone 2 fit tightly in taper hole 1 inwall at last and fixes to moving.The utility model assembly manipulation is simple, and taper hole 1 is a taper fit with the axis of cone 2, cooperates no gap, good fixing effect; In the cutting process, because the self-locking action that turnbuckle 31 cooperates with the thread of taper pin 32, locking device 3 is difficult for loosening, and it is strong to connect steadiness.
The utility model can be applied to various cutters such as boring cutter, lathe tool, and the fixedlying connected of other machining tool and stock-removing machine, and is applied widely.
When needing the dismounting and the instrument of replacing, only need oppositely turn turnbuckle 31, make described taper pin 32 withdraw from described connecting hole 21, thereby remove locking state, and finally make the axis of cone 2 can break away from taper hole 1, so that on machine tool chief axis, connect different instruments.
See Fig. 2 and shown in Figure 3, turnbuckle 31 described in the utility model is the turnbuckle of double end tooth screw-type, and described turnbuckle 31 two ends threads oppositely are provided with, and the two ends of described turnbuckle 31 are bolted with described taper pin 32 respectively.Particularly, the internal thread hole of described taper pin 32 is for axially running through the hole of taper pin 32, and the thread specification at turnbuckle 31 two ends is identical, and rotation direction is opposite.Like this, in the assembling process, turn turnbuckle 31, taper pin 32 locking phases that then are bolted in turnbuckle 31 two ends are to axial along turnbuckle 31, and promptly F as shown in Figure 1 is to moving.The retaining mechanism of this structure is in assembling process, and taper pin 32 stretches into respectively simultaneously from the two ends of described connecting hole 21, promotes the axis of cone 2 at N stress equalization in moving process, moves steadily, and then makes hole axle fiting effect better.
Preferably, the bellmouth that the part of the described connecting hole 21 close axis of cone 2 circumferential surfaces is complementary for the taper surface with described taper pin 32, the taper surface of described bellmouth inwall and described taper pin 32 fits tightly during locking.Like this, finish assembling, after the axis of cone 2 lock onto taper hole 1, the taper surface of described taper pin 32 cooperated no gap with described connecting hole 21, has increased bonding strength and coupling stiffness, has strengthened the dependability of instrument.
More preferably, described pin-and-hole 11 is and the consistent taper pin-hole 11 of described taper pin 32 taper surface taperings that the taper surface of described pin-and-hole 11 inwalls and described taper pin 32 fits tightly during locking.In like manner, this has also increased bonding strength and rigidity.
See Fig. 2 and shown in Figure 3, the axis of cone 2 top end diameters described in the utility model are to offering the open slot 22 that is communicated with described connecting hole 21, described open slot 22 cell body width are not less than described turnbuckle 31 diameters, and are not more than the maximum caliber that described taper pin 32 stretches into connecting hole 21 parts.Like this, in assembling process, can earlier locking device 3 be inserted the connecting hole 21 of described taper hole 1, again with the open slot 22 of the axis of cone 2 over against described turnbuckle 31, and the axis of cone 2 pushed in the described taper hole 1, make turnbuckle 31 pass described open slot 22 and enter described connecting hole 21, tighten turnbuckle 31 again and realize being locked.This has improved the assembling convenience, has improved the instrument efficiency of assembling.
Wherein, described pin-and-hole 11 inwalls offer gap slot, and described guide pad 12 removably is fixed in described gap slot.Be convenient to dismounting like this or change guide pad 12, make assembling more convenient on the one hand, can change wearing and tearing on the other hand and with the guide pad 12 of gathering sill 321 poor fits, improved connection steadiness of the present utility model.
Particularly, described gap slot can be along described pin-and-hole 11 axis direction settings, described guide pad 12 is bolted in described gap slot, the gathering sill 321 of described taper pin 32 is the circular arc shaped guide slots 321 that is complementary with described guide pad 12 circumferential surfaces, and described guide pad 12 is tight against described gathering sill 321 bottom lands during locking.
See shown in Figure 3ly, the described axis of cone 2 big ends radially convex with step surface 23 along the axis of cone 2, and described step surface 23 is tight against described taper hole 1 end during locking.Like this, finish assembling after, the axis of cone 2 does not have the gap assembling with taper hole 1 taper fit, and described step surface 23 fits tightly with taper hole 1 end face, retrains the relative position of the axis of cone 2 and taper hole 1 jointly, makes assembling more firm, reliability is higher.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
