Abstract
The utility model belongs to the technical field of the machine tool accessory technique and specifically relates to a whole 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 is connected with big bevel gear meshing, is equipped with the routed chamber of contracting on being equipped with expansion board, expansion board on the jack catch, and the routed intracavity that contracts is equipped with spring and inner panel. Front end at every jack catch sets up curved expansion board, passes through spring telescopic connection inner panel at the both ends of every expansion board simultaneously, forms the whole mechanism that surrounds. During the use, along with the propulsion of jack catch, the expansion board centering is gathered together, and adjacent inner panel pushes the shrink each other, docks into a holistic circle, surrounds in the periphery of pipe fitting, forms whole centre gripping to the pipe fitting, and area of contact is big, and the application of force is even, has avoided not only that the local stress is too big to lead to the fact the damage, has improved the control in addition greatly.
Description
Technical field
The utility model relates to machine tool accessories technical field, especially a kind of monolithic devices 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, contact area is little, and not only control is little, and easily causes local stress excessive, damage pipe fitting.
Utility model content
Weak in order to overcome the little control of existing scroll chuck holding area, the deficiency that local stress is large, the utility model provides a kind of monolithic devices scroll chuck.
The utility model solves the technical scheme that its technical problem adopts: a kind of monolithic devices 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 expansion board, expansion board is provided with crumple chamber, is provided with spring and inner panel in crumple chamber.
According to another embodiment of the present utility model, comprise expansion board further curved, top is connected to the front end of claw.
According to another embodiment of the present utility model, comprise the two ends that crumple chamber is positioned at expansion board further, spring is inlaid in crumple chamber.
According to another embodiment of the present utility model, comprise inner panel further and be connected in crumple chamber by telescopic spring.
The beneficial effects of the utility model are, arrange the expansion board of arc in the front end of every claw, connect inner panel at the two ends of every expansion board by telescopic spring simultaneously, form overall encirclement mechanism.During use, along with the propelling of claw, expansion board is gathered to center, and adjacent inner panel extrudes contraction mutually, is butted into an overall circle, be enclosed in the periphery of pipe fitting, form integral retaining to pipe fitting, contact area is large, uniform force application, not only avoid that local stress is excessive causes damage, and substantially increase control.
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. expansion board in figure, 6. crumple chamber, 7. spring, 8. Inner plate.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of monolithic devices 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 expansion board 5, expansion board 5 is provided with crumple chamber 6, is provided with spring 7 and inner panel 8 in crumple chamber 6.Expansion board 5 is curved, and top is connected to the front end of claw 2.Crumple chamber 6 is positioned at the two ends of expansion board 5, and spring 7 is inlaid in crumple chamber 6.Inner panel 8 is connected in crumple chamber 6 by spring 7 is flexible.
Arrange the expansion board 5 of arc in the front end of every claw 2, connect inner panel 8 simultaneously at the two ends of every expansion board 5 by spring 7 is flexible, formation is overall surrounds mechanism.During use, along with the propelling of claw 2, expansion board 5 is gathered to center, and adjacent inner panel 8 extrudes contraction mutually, is butted into an overall circle, be enclosed in the periphery of pipe fitting, form integral retaining to pipe fitting, contact area is large, uniform force application, not only avoid that local stress is excessive causes damage, and substantially increase control.
