Abstract
The present invention introduces a kind of chucking device of the tail stock with chuck, is related to lathe cutting techniques field, is particularly applied to the chucking device in the case that large and medium-sized lathe increases load-bearing.Chucking device of the tail stock of the present invention with chuck is mainly spindle chuck clamping, and the chucking device of tailstock chuck clamping is made of the locking of tailstock, barrel of tail stock, tailstock main shaft, chuck and bolt.Barrel of tail stock is connected by guide pin with tailstock, only axially retractable, can not do rotary motion.It is embedded in tailstock main shaft in barrel of tail stock, between the two by bearing support, realizes rotary motion.Chuck is connected as one by screw and tailstock main shaft.Gland is fixed on barrel of tail stock, and barrel of tail stock can be connected and fixed with tailstock main shaft by bolt and gland, is inserted into bolt, then tailstock main shaft can not do rotary motion as barrel of tail stock.Bolt is unclamped, then can be turned round together with chuck.The present invention is applied to large and medium-sized lathe, when carrying bigger, is clamped using spindle chuck, and the chucking device of tailstock chuck clamping realizes enhancing carrying and revolute function.
Description
Technical field
The present invention relates to lathe cutting techniques fields, are particularly applied to large and medium-sized lathe and increase being loaded under load-bearing conditions
Device.
Background technique
Traditional large and medium-sized lathe is clamped, the dress that tailstock centre is held out against when carrying bigger using spindle chuck
Folder mode can generate very big axial force, tailstock and barrel of tail stock spring bearing for top and tailstock by top main carrying
Stress is big, damages more.Invention describes the structures of a kind of clamping of spindle chuck, tailstock chuck clamping, will significantly
Bearing capacity and revolute function are promoted, it is relatively reasonable in structure.
Summary of the invention
The present invention proposes a kind of spindle chuck clamping, the chucking device of tailstock chuck clamping, and technical problems to be solved are
Large and medium-sized lathe is when carrying bigger, the installation way held out against using spindle chuck clamping, tailstock centre, by top master
It carries, very big axial force can be generated for top and tailstock main shaft, tailstock and barrel of tail stock spring bearing stress are big, damage
More situation provides a kind of chucking device of the tailstock with chuck, and structure is simple, easy to operate.
Chucking device of the tail stock with chuck is mainly that spindle chuck clamps, the chucking device of tailstock chuck clamping, by
Tailstock 8, barrel of tail stock 11, tailstock main shaft 1, chuck 2 and the locking composition of bolt 6.
Chucking device of the tail stock of the present invention with chuck is applied to large and medium-sized lathe, when carrying bigger, adopts
It is clamped with spindle chuck, the chucking device of tailstock chuck clamping realizes enhancing carrying and revolute function.
The tailstock 8, barrel of tail stock 11, chuck 2 is unloaded, and is loaded onto top 3 and is connect with tailstock main shaft 1 by Morse's taper,
Bolt 6 is placed in pins position, and with screw 4 tightly, tailstock main shaft 1 is connected by bolt 6 and sleeve 11 by guide pin 12 and tailstock 11
It connects, locking pin 9 locks tailstock, realizes the brill boring function of tailstock, mandril 10 can be by top 3 from 1 mohs tapered bore of tailstock main shaft
Ejection.
Bolt 6 is placed in released position by the tailstock main shaft 1, and chuck 2 is fixedly connected by screw 5 with main shaft, Ke Yitong
Crossing spindle chuck revolution drives tailstock chuck to pass through tailstock main shaft 1, bearing 7, and bearing 13 turns round in barrel of tail stock 11, tailstock card
Disk provides enhancing support force.
Technical process: barrel of tail stock 11 is connected by guide pin 12 with tailstock 8, only axially retractable, can not be turned round
Movement.It is embedded in tailstock main shaft 1 in barrel of tail stock 11, is supported between the two by bearing 7, bearing 13, realizes rotary motion.Chuck
2 are connected as one by screw 5 with tailstock main shaft 1.Gland 15 is fixed on barrel of tail stock, barrel of tail stock 11 and tailstock main shaft 1
It can be connected and fixed by bolt 6 and gland 15, be inserted into bolt 6, then tailstock main shaft 1 and barrel of tail stock 11 can not do rotary motion.Pine
Bolt is opened, then can be turned round together with chuck 2.
The invention has the advantages that providing, a kind of structure is simple, easy to operate chucking device, solves large and medium-sized lathe in carrying ratio
When larger, using spindle chuck clamping, the installation way that holds out against of tailstock centre, by top main carrying, for top and
Tailstock generates very big axial force, and tailstock and barrel of tail stock spring bearing stress are big, damages more situation, promotes carrying energy
Power, enhancing revolute function.
