Abstract
The utility model belongs to the technical field of the machine tool accessory technique and specifically relates to a tight 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 ejector pin and spring on the jack catch, and the front end of ejector pin is equipped with base and clamp plate. At the front end telescopic connection of every jack catch ejector pin, the while forms double -deck clamping mechanism at the elastic pressure plate of the fixed root circle arcuation of front end of every ejector pin. During the use, along with the propulsion of jack catch, the ejector pin centering is gathered together, and through the tight pipe fitting of clamp plate clamp, the spring deforms under the pressure of jack catch, exerts first layer elasticity pretightning force through the ejector pin to the pipe fitting, and simultaneously, the clamp plate deforms under the pressure of ejector pin, develops with the pipe fitting, exerts second floor elasticity pretightning force to the pipe fitting, effectively prevents to become flexible, has guaranteed clamping -force's validity to the centre gripping effect has been improved.
Description
Technical field
The utility model relates to machine tool accessories technical field, especially a kind of tight 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 all disposable rigid clamping, position is fixed, and cannot adjust again, in use easily loosen, and causes chucking power to weaken, affects clamping effect.
Utility model content
Easily loosening to overcome existing scroll chuck, affecting the deficiency of clamping effect, the utility model provides a kind of tight type scroll chuck.
The utility model solves the technical scheme that its technical problem adopts: a kind of tight 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 push rod and spring, and the front end of push rod is provided with pedestal and pressing plate.
According to another embodiment of the present utility model, comprise the front end that push rod is inserted in claw further, be slidably connected with claw.
According to another embodiment of the present utility model, comprise spring housing further on push rod, be stuck between claw and pedestal.
According to another embodiment of the present utility model, comprising pressing plate is further elastic metal sheet, in arc-shaped, is connected to the front end of pedestal.
The beneficial effects of the utility model are, connect push rod in the front end of every claw by telescopic spring, fix the spring bearer plate of an arc-shaped simultaneously, form double-deck clamp system in the front end of every push rod by pedestal.During use, along with the propelling of claw, push rod is gathered to center, by platen clamp pipe fitting, spring deformation under the pressure of claw, applies ground floor elastic pre-stress by push rod to pipe fitting, simultaneously, pressing plate deformation under the pressure of push rod, develop with pipe fitting, second layer elastic pre-stress is applied to pipe fitting, effectively prevents from loosening, ensure that the validity of chucking power, thus improve clamping 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. push rod, 6. spring, 7. pedestal, 8. pressing plate in figure.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of tight 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 push rod 5 and spring 6, and the front end of push rod 5 is provided with pedestal 7 and pressing plate 8.Push rod 5 is inserted in the front end of claw 2, is slidably connected with claw 2.Spring 6 is enclosed within push rod 5, is stuck between claw 2 and pedestal 7.Pressing plate 8 is elastic metal sheet, in arc-shaped, is connected to the front end of pedestal 7.
Connect push rod 5 in the front end of every claw 2 by spring 6 is flexible, fixed the flexible pressing plate 8 of an arc-shaped simultaneously in the front end of every push rod 5 by pedestal 7, form double-deck clamp system.During use, along with the propelling of claw 2, push rod 5 is gathered to center, pipe fitting is clamped by pressing plate 8, spring 6 deformation under the pressure of claw 2, applies ground floor elastic pre-stress by push rod 5 pairs of pipe fittings, simultaneously, pressing plate 8 deformation under the pressure of push rod 5, develop with pipe fitting, second layer elastic pre-stress is applied to pipe fitting, effectively prevents from loosening, ensure that the validity of chucking power, thus improve clamping effect.
