Description
Technical field
The utility model relates to a kind of changeable type automatic clamping chuck device, specifically is used for the numerically controlled lathe clamping work pieces, belongs to the Digit Control Machine Tool equipment technical field.
Background technology
In the manufacturing industry, generally adopted Digit Control Machine Tool to substitute ordinary machine tool in modern times, enhanced productivity, so numerically controlled lathe is more and more in present Application in Manufacturing Industry.Workpiece processing all needs anchor clamps to fix workpiece, and in numerically controlled lathe, clamping work pieces generally has two kinds: chuck and chuck.For the chuck clamping work pieces, at present, be a kind of anchor clamps wherein commonly used, its form and of a great variety, mounting means also has nothing in common with each other.In general, chuck at work clamping work pieces with unclamp workpiece and all need hydraulic gyration oil cylinder or air pressure rotary cylinder to move.Required auxiliary is many and cost an arm and a leg.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned weak point, thereby a kind of changeable type automatic clamping chuck device is provided, and can realize that the shared cover mechanical device of many sizes carries out the automatic card-loading of workpiece through changing chuck, and simple in structure, cost is low.
The technical scheme that provides according to the utility model; The changeable type automatic clamping chuck device mainly comprises main shaft, ring flange, stop nut, chuck, adapter sleeve, spring and promotion pipe; Said main shaft is installed on the lathe casing, and the main shaft outside is through the screw mounting flange; Said ring flange outer end is provided with screw thread, and stop nut is connected with ring flange through screw thread.
Said promotion pipe is installed in the main shaft, manages through the power set drive promotion of rear-end of spindle to seesaw vertically.Said promotion pipe outer end is provided with adapter sleeve, mounting spring in the adapter sleeve.Said spring outer end connects chuck.
Be provided with step in the said adapter sleeve, the step left side connects the promotion pipe, and the step right side connects spring.Said adapter sleeve outer end inner chamber from inside to outside is ascending bellmouth.
The outer end of said chuck is a bullet, and bullet is from inside to outside ascending gradually.Said bullet is provided with four mutually perpendicular notches, through the strain clamping work pieces of notch.
Hand of spiral on the said ring flange is opposite with the direction of rotation of main shaft.
Compared with present technology the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Adopted the form of replaceable chuck, can realize that the shared cover mechanical device of many sizes carries out the automatic card-loading of workpiece through changing chuck; Only need simple thrust unit can unclamp chuck, reduced cost.

The specific embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
Shown in Fig. 1 ~ 2, the utility model mainly comprises main shaft 2, ring flange 4, stop nut 5, chuck 6, adapter sleeve 7, spring 8 and promotes to manage 9 that said main shaft 2 is installed on the lathe casing 1, and main shaft 2 outsides are through screw 3 mounting flanges 4; Said ring flange 4 outer ends are provided with screw thread, and stop nut 5 is connected with ring flange 4 through screw thread.
Said promotion pipe 9 is installed in the main shaft 2, manages 9 through the power set drive promotion of main shaft 2 rear ends and seesaws vertically.Said promotion is managed 9 outer ends adapter sleeve 7 is set, mounting spring 8 in the adapter sleeve 7.Said spring 8 outer ends connect chuck 6.
Be provided with step 10 in the said adapter sleeve 7, step 10 left sides connect promotion pipe 9, and step 10 right sides connect spring 8.Said adapter sleeve 7 outer end inner chambers from inside to outside are ascending bellmouth.
The outer end of said chuck 6 is a bullet 11, and bullet 11 is from inside to outside ascending gradually.Said bullet 11 is provided with four mutually perpendicular notches 12.Said notch 12 can produce strain by pressurized, thus clamping work pieces.
Hand of spiral on the said ring flange 4 is opposite with the direction of rotation of main shaft, and during main shaft 2 rotations, it is tight more that stop nut 5 changes more, guaranteed the tight ness rating and the security that connect.
Be directed to the little situation of the scope that is installed of every kind of chuck 6, designed the chuck 6 of plurality of specifications, when other diameter specifications of needs, only need stop nut 5 is backed out, change chuck 6.The dismounting of this kind structure is all very convenient, can be good at realizing the automatic card-loading of workpiece.
The operation principle of the utility model is:
When the needs clamping work pieces, drive by the power set of main shaft 2 tail ends and to promote outwards motion of pipe 9, promote pipe 9 and promote adapter sleeve 7 again and outwards move the spring 8 promotion chucks 6 of adapter sleeve 7 through compressing.The stop nut 5 that is positioned at the ring flange end has limited chuck 6 motion to the right, the end clips clamping of workpieces of the front end bellmouth compressing chuck 6 of adapter sleeve 7.When adapter sleeve 7 moves right, will produce a compression stress after spring 8 is compressed and hold out against chuck 6 to the right.
When needs unclamped workpiece, cancellation promoted the motive force of pipe 9, promoted pipe 9 after the compression stress of spring 8 obtains discharging and resetted.At this moment, chuck 6 does not receive the radial pressure of adapter sleeve 7, outwards recovers distortion, and workpiece is released.After spring 8 promoted adapter sleeve 7, spring 8 itself also had certain compression stress that chuck 6 is closely contacted with stop nut 5, prevents that chuck 6 from rocking in adapter sleeve 7.
