Abstract
The utility model relates to a three-jaws centering automatic chuck, which is widely used on cutting machine tools. The utility model mainly comprises a back cover, a chuck body, a chuck base, a scroll, three jaws, a rising brake which is hinged with the a back cover and is arranged in the chuck body, and a wobble shaft which controls the rising brake to be opened and closed, wherein, the scroll is fixedly connected with a main shaft of a machine tool, and the chuck body is fixedly connected with the chuck base. The clamping or loosening of workpieces can be realized through applying rotary force on the wobble shaft when the main shaft of the machine tool is in the condition of positive rotation or reversion. The utility model is characterized in that the clamping or loosening of the workpieces does not need stopping, so the time can be saved; besides the automation of the clamping or loosening of the workpieces can be realized on the automatic machine tool or the semi-automatic machine tool. Thus, the clamping force is stable and reliable and can be automatically supplied in the process of cutting the workpieces, and the generation of wasters can be avoided.
Description
The utility model relates to a kind of three-jaw centering chuck that extensively is used on the Metal Cutting Machine Tools such as lathe, milling machine, grinding machine.
The existing three-jaw centering chuck that is used on the Metal Cutting Machine Tool mainly is made of parts such as chuck body, silk dish, claw, spanner seat, rear pressing cover and chuck spanners.Three spanner seats are respectively charged in the hole of three five equilibriums of chuck body cylinder and can freely rotate, its umbrella tooth is meshed with a umbrella tooth that coils, rotate spanner seat with spanner, and drive silk dish rotates in chuck body, the screw thread that spirals of the silk dish opposite side moving claw of cingulum that promptly spirals moves in the trisection slot of chuck body end face respectively, thereby realizes the chucking of workpiece or unclamp.The deficiency that this three-jaw centering chuck exists is the chucking of workpiece or unclamps and must can rotate spanner with hand at the emergency rear, thereby is time-consuming effort again, and is difficult to realize automation; Workpiece is in the cutwork process in addition, and clamping force can not replenish foot, thereby easily causes waste product and accident.
At the deficiency that above-mentioned prior art exists, it is big and reliable and stable that the purpose of this utility model provides a kind of clamping force, and operation saves time, labour-saving three-jaw centering automatic chuck.
The purpose of this utility model is achieved in that the rise camshaft of lock of rise lock and unlatching that it comprises bonnet, chuck body, chuck seat, silk dish and and buckle three claws that screw mutually and can move freely with spiraling of this dish in three five equilibrium grooves of chuck body end face and is located at chuck seat inside, lock and the bonnet strand that rises connects, the silk dish is connected with machine tool chief axis, and chuck seat places between bonnet and the chuck body and with chuck body and is connected.Machine tool chief axis rotates then whole chuck (comprising chuck body, chuck seat, claw and silk dish) and and then rotates together.The chucking workpiece is when main shaft just changes, and by applying one of camshaft rotation external force (as the pedal by stepping on the camshaft that is dynamically connected or manually or by Automatic Lathe give a revolving force), it is rotated to an angle, and the lock that will rise is opened.Make chuck seat and chuck body stop the rotation, silk dish then still is rotated in the forward under main shaft drives, and drives three claws by it and move to the center in three five equilibrium grooves of chuck body end face workpiece is tightened.The lock elasticity that rises self-return then workpiece enters cutting process.Unclamping workpiece is when main shaft reverses, and by applying a rotation of camshaft external force, makes angle of its rotation, the lock that will rise is opened, and chuck seat and chuck body are stopped operating, the reverse rotation under main shaft drives of silk dish, outwards move thereby drive claw, finish unclamping of workpiece.
Characteristics of the present utility model are: the chucking of (1), workpiece with unclamp all need not stop (being that main shaft does not stop the rotation), can realize tightening automatically or unclamping as long as apply a revolving force to camshaft.Thereby save time, particularly be convenient to be used in and realize automation control on automatic machine tool or the semi-automatic controlling machine; (2), be active in one's movements, clamping force is big and reliable and stable, can replenish clamping force automatically in the workpiece working angles.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation, and it mainly comprises among bonnet 3, chuck seat 4, chuck body 6, three claw 5(figure only draws two), silk dish 9, lock 8 and camshaft 11 rise.Silk dish 9 is connected by soket head cap screw 7 and machine tool chief axis 14, and chuck body 6 is connected by soket head cap screw 10 and chuck seat 4.Three claws 5 are located at respectively in three five equilibrium grooves of chuck body 6 end faces and screw mutually with the button that spirals that silk coils 9 one sides, the rise front portion of lock 8 and camshaft 11 is arranged on chuck seat 4 inside, the lock 8 that rises connects with bonnet 3 lines, unlatching by camshaft 11 controls rising lock 8, camshaft 11 rear portions one side can connect a pedal 13 that camshaft is rotated to an angle, when the main shaft forward or reverse, but by just control card pawl chucking workpiece or unclamp workpiece of pedal 13, in the accompanying drawing sequence number 1 be bearing shell, 2 for box cover, 12 be casing.
