Abstract
The utility model belongs to the technical field of the machine tool accessory technique and specifically relates to a disjunctor type three -jaw chuck. It includes disk body, jack catch, little bevel gear and big bevel gear, and jack catch and little bevel gear are located the tip and the lateral part of disk body respectively, and big bevel gear is located the inside of disk body, and little bevel gear meshes with big bevel gear and is connected, is equipped with extension spring and telescopic link on being equipped with lug, lug on the jack catch, is equipped with adjusting nut on the telescopic link. A pair of lug of bilateral symmetry distribution at every jack catch to connect a telescopic link through the extension spring on the lug between adjacent two jack catchs, form disjunctor mechanism. During the use, three jack catchs link into an integrated entity, form the pipe fitting and surround, exert holistic pressure, behind the double -layered tight pipe fitting of jack catch, shorten the telescopic link through rotated adjusting nut, further strengthen whole cohesiveness to keep the pretightning force under the effect of extension spring, thereby strengthened whole centre gripping effect greatly.
Description
Technical field
The utility model relates to machine tool accessories technical field, especially a kind of connection type scroll chuck.
Background technology
Scroll chuck utilizes to be distributed on moving radially of three movable jaws on chuck body, the machine tool accessories of Workpiece clamping and location.Existing scroll chuck structure is simple, and be three-point contact type, can only clamp the local of pipe fitting, pressure dissipation, integral retaining power is little, and clamping effect is poor.
Utility model content
In order to overcome existing scroll chuck pressure dissipation, the deficiency that integral retaining power is little, the utility model provides a kind of connection type scroll chuck.
The utility model solves the technical scheme that its technical problem adopts: a kind of connection type scroll chuck, comprise disk body, claw, bevel pinion and bevel gear wheel, claw and bevel pinion lay respectively at end and the sidepiece of disk body, bevel gear wheel is positioned at the inside of disk body, bevel pinion and bevel gear wheel are connected with a joggle, claw is provided with hanger, hanger is provided with extension spring and expansion link, and expansion link is provided with adjusting nut.
According to another embodiment of the present utility model, comprise the both sides that hanger is symmetrically distributed in claw further.
According to another embodiment of the present utility model, comprise expansion link further and be connected on the hanger between adjacent two claws by extension spring.
According to another embodiment of the present utility model, comprise the two ends that extension spring is connected to expansion link further, adjusting nut is enclosed within the middle part of expansion link.
The beneficial effects of the utility model are, to distribute a pair hanger in the bilateral symmetry of every claw, and hanger between adjacent two claws connects an expansion link by extension spring, form disjunctor mechanism.During use, three claws link into an integrated entity, and formed surround pipe fitting, apply overall pressure, when after claw clamping pipe fitting, shorten expansion link by rotating adjusting nut, the overall cohesiveness of further enhancing, and pretightning force is kept under the effect of extension spring, thus greatly strengthen integral retaining effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. disk bodies, 2. claw, 3. bevel pinion, 4. bevel gear wheel, 5. hanger, 6. extension spring, 7. expansion link, 8. adjusting nut in figure.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of connection type scroll chuck, comprise disk body 1, claw 2, bevel pinion 3 and bevel gear wheel 4, claw 2 and bevel pinion 3 lay respectively at end and the sidepiece of disk body 1, bevel gear wheel 4 is positioned at the inside of disk body 1, bevel pinion 3 and bevel gear wheel 4 are connected with a joggle, and claw 2 is provided with hanger 5, hanger 5 is provided with extension spring 6 and expansion link 7, and expansion link 7 is provided with adjusting nut 8.Hanger 5 is symmetrically distributed in the both sides of claw 2.Expansion link 7 is connected on the hanger 5 between adjacent two claws 2 by extension spring 6.Extension spring 6 is connected to the two ends of expansion link 7, and adjusting nut 8 is enclosed within the middle part of expansion link 7.
To distribute a pair hanger 5 in the bilateral symmetry of every claw 2, and hanger 5 between adjacent two claws 2 connects an expansion link 7 by extension spring 6, form disjunctor mechanism.During use, three claws 2 link into an integrated entity, pipe fitting is formed and surrounds, apply overall pressure, after claw 2 clamps pipe fitting, shorten expansion link 7 by rotating adjusting nut 8, strengthen overall cohesiveness further, and keep pretightning force under the effect of extension spring 6, thus greatly strengthen integral retaining effect.
