Under the premise of chucking power when making, carries out one group of butterfly spring piece to be compressed to designated length, be mounted directly main shaft in machining center
On pull rod, to complete the installation of machining center main shaft spring lamination.
The utility model is realized in this way: a kind of machining center main shaft spring piece mounting device, including sleeve, locating core
Axis, location nut, guide sleeve, guide sleeve holding screw, main shaft pull rod, butterfly spring piece, preceding washer, rear washer, main shaft pull rod
Front end locking nut and hanging ring, guide sleeve are installed on positioning core axle, between positioning core axle and barrel forward end inner hole, sleeve
Head figure design is hexagon, and sleeve passes through screw thread by guide sleeve holding screw, one end head inner bolt hole of sleeve and guide sleeve
It is fixedly connected, the sleeve other end is equipped with location nut and hanging ring, is threadedly coupled between location nut and sleeve, and hanging ring tail portion is passed through
It wears location nut inner hole and is threadably secured with positioning core axle one end and is connect, preceding washer and rear washer and butterfly spring piece are located at
In the inner cavity that positioning core axle and hub internal bore are constituted, butterfly spring piece positioned at preceding washer and rear washer between, sleeve rear end with calmly
Position nut thread connection, between positioning core axle and sleeve, location nut outer end face is fixedly connected location nut with hanging ring.
This machining center main shaft spring piece mounting device, takes and carries out one group of butterfly spring piece to be compressed to designated length,
It is mounted directly on main shaft pull rod in machining center, to complete the installation of machining center main shaft spring lamination, time saving province is installed
Power, securely and reliably.
Detailed description of the invention
Fig. 1 is machining center main shaft spring piece mounting device structural schematic diagram；
Fig. 2 is main axis spring piece installation process schematic diagram；
Fig. 3 is main axis spring piece scheme of installation.
In figure, 1 is sleeve, and 2 be positioning core axle, and 3 be location nut, and 4 be guide sleeve, and 5 be guide sleeve holding screw, and 6 are
Main shaft pull rod, 7 be butterfly spring piece, and 8 be preceding washer, and 9 be rear washer, and 10 be main shaft pull rod front end locking nut, and 11 be locking
Nut holding screw, 12 be hanging ring, and 13 be machine tool chief axis.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing,
As shown in Figure 1, 2, 3, a kind of machining center main shaft spring piece mounting device, feature include sleeve 1, positioning core axle
2, location nut 3, guide sleeve 4, guide sleeve holding screw 5, main shaft pull rod 6, butterfly spring piece 7, preceding washer 8, rear washer 9, master
Axis draw lever locking nut 10, locking nut holding screw 11 and hanging ring 12, guide sleeve 4 are installed in sleeve 1, are located at positioning core axle
Between 2 and 1 front end inner hole of sleeve, 1 Head figure design of sleeve is hexagon, the guiding being installed in radial screw hole on outer-hexagonal
Holding screw 5 is covered, sleeve 1 is fixedly connected with guide sleeve 4, preceding washer 8 and rear washer 9 and butterfly spring piece 7 are located at positioning
In the inner cavity that mandrel 2 and 1 inner hole of sleeve are constituted, wherein butterfly spring piece 7 is between preceding washer 8 and rear washer 9, after sleeve 1
End is threadedly coupled with location nut 3, and location nut 3 is between positioning core axle 2 and sleeve 1, between location nut 3 and sleeve 1
It is threadedly coupled, 12 tail portion of hanging ring is threadably secured with one end inner hole of positioning core axle 2 through 3 inner hole of location nut and connect.Peace
When dress, first by the outer-hexagonal of 1 front end of scroll chuck closing sleeve, 4 outer diameter of guide sleeve is matched with 1 front end inner hole of sleeve at transition
It closes, the guide sleeve 4 being installed on the outer-hexagonal of 1 front end of sleeve in radial screw hole, holding screw 5,3 external screw thread of location nut and set
The internal thread hole connection of 1 rear end of cylinder, reach need reduction length 25mm more than butterfly spring piece 7, it is ensured that when subsequent compression
