The invention provides a kind of lathe clamping mechanism, comprise: comprise main spindle box body 1, main shaft 2 and holder 3, the rotatable inside being located at main spindle box body 1 of described main shaft 2, described holder 3 is connected on main shaft 2, it is characterized in that, also comprise and make clamping part 3 carry out clamping by push-and-pull or unclamp the push-pull device at fixed 4 of workpiece and make push-pull device at fixed 4 carry out the rocker arrangement 5 of push pull maneuver, the adjusting device 6 that the chucking power size of workpiece is regulated can also be comprised.
The inside of described main shaft 2 is provided with service aisle 21 in the axial direction; Described holder 3 preferably includes chuck 31 and collet chuck 32, the rear end of described chuck 31 is connected on the leading section of main shaft 2, a scarf is formed between the front end of described chuck 31 and inwall, the front end outer wall of described collet chuck 32 is provided with scarf, it is inner that described collet chuck 32 is connected on chuck 31 by scarf engagement sleeves, and the inside of described collet chuck 32 is provided with piece-holder passage 321 along its axis direction; Described push-pull device at fixed 4 preferably includes pull bar 41, pull-push piece 42, butterfly spring 43 and work push pedal 44, the rear end of described pull bar 41 is connected in workpiece push pedal 44, middle part has been fixed by socket pull-push piece 42, front end is passed the service aisle 21 of main shaft 2 and is socketed in chuck 31 inside, and the front end face contact of pull bar 41 is on the rear end face of collet chuck 32, described butterfly spring 43 is socketed on pull bar 41, its rear end contact is in pull-push piece 42, and the part except its rear end is limited in a fixed space suitable with its shape.Like this when pull bar 41 is pushed forward, pull-push piece 42 extrudes butterfly spring 43, makes it store certain potential energy, and when pull bar 41 needs to recover original position, the potential energy that release stores is retracted.
Described push-pull device at fixed 4 also preferably includes auxiliary mounting flange 45, and described butterfly spring 43 front end contact, on main shaft 2 rear end, is socketed with auxiliary mounting flange 45 outside it, the rear inner wall sleeve of described auxiliary mounting flange 45 is connected to pull-push piece 42.The part of butterfly spring 43 except its rear end here just can be limited in a fixed space suitable with its shape by described auxiliary mounting flange 45.
The front end of described main shaft 2 is preferably provided with scalene cone, and the rear end of described chuck 31 is preferably provided with the scalene cone suitable with the front end geometry of main shaft 2, and the rear end of described chuck 31 and the front end of main shaft 2 are connected preferably by scalene cone.
Described rocker arrangement 5 preferably includes fixed head 51, rocking lever mount pad 52, rocking lever 53, power unit 54 and spring 55, described fixed head 51 is connected on main spindle box body 1, described rocking lever mount pad 52 is connected on fixed head 51, the front end of described rocking lever 53 is connected in workpiece push pedal 44, middle part is hinged on rocking lever mount pad 52, described power unit 54 is cylinder or oil cylinder, the end of the connecting rod of cylinder or oil cylinder and the rear side of rocking lever 53 are oppositely arranged, described spring 55 one end is connected to rocking lever 53 rear portion, the other end is fixed on rocking lever mount pad 52, described cylinder or oil cylinder, spring 55 and workpiece push pedal 44 are all arranged on the homonymy of rocking lever 53.
Described adjusting device preferably includes the locking nut as pull-push piece 42, and described locking nut thread bush is connected on pull bar 41, and the service aisle 21 of the front end of described main shaft 2 and the front end of described pull bar 41 all form a pre-large post-small structure.Like this when pull bar 41 restore to the original state need to pull back time or can avoid when locking nut regulates the chucking power needed for workpiece unrestrictedly moving backward.
The workflow of described lathe clamping mechanism, is divided into clamping workpiece, unclamps workpiece and three parts that restore to the original state.
Clamping workpiece: workpiece is loaded in collet chuck 32, then collet chuck 32 is connected on chuck 31 by scarf engagement sleeves inner, front end shape deforming clip clamping of workpieces under the effect of chuck 31 of collet chuck 32, now pull bar 41 is in contraction state under the effect of butterfly spring 43, rotated by belt pulley drive shaft 2, the chuck 31 be connected on main shaft 2 drives collet chuck 32 and workpiece also to rotate thereupon, thus can carry out the machining of workpiece.
Unclamp workpiece: start cylinder or oil cylinder, cylinder or oil cylinder pass through the rear side of the connecting rod percussion rocking lever 53 on it, middle part because of rocking lever 53 is hinged on rocking lever mount pad 52, its front end percussion work push pedal 44 can be driven, work push pedal 44 drives forwards pull bar 41, collet chuck 32 ejects forward by the front end of pull bar 41, collet chuck 32 is gradually away from chuck 31, collet chuck 32 also reduces with the fitness of the scarf of chuck 31 thereupon, the piece-holder passage 321 of collet chuck 32 increases gradually, achieves loosening workpiece.
Restore to the original state: shifter cylinder or oil cylinder, after connecting rod on it shrinks; the rear portion of rocking lever 53 elastically-deformable spring 55 is occurred retracts unclamping in workpiece fabrication; the middle part because of rocking lever 53 is hinged on rocking lever mount pad 52; its front end can be driven toward post-tensioning; work push pedal 44 also returns to original position thereupon; because butterfly spring 43 is squeezed unclamping in workpiece fabrication; need to discharge potential energy; produce an active force backward to pull-push piece 42 on pull bar 41, pull bar 41 returns to original position gradually.
When needing to regulate the chucking power needed for different workpiece, can unscrew or tighten locking nut, namely the position of locking nut on pull bar 41 is changed, thus change the relative position of pull bar 41 and main shaft 2, because the front end face contact of pull bar 41 is on the rear end face of collet chuck 32, the front and back position of pull bar 41 in main shaft 2 is different, collet chuck 32 is also different from the relative position of chuck 31 or main shaft 2, collet chuck 32 is also variant with the fitness of the scarf of chuck 31, thus the adjustment realized piece-holder passage 321 size of collet chuck 32, piece-holder passage 321 size just determines the size of chucking power.
