Abstract
The utility model belongs to the technical field of the machine tool accessory technique and specifically relates to a two -way 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 push rod on the jack catch, is equipped with the depression bar on the push rod, is equipped with the clamp plate on the depression bar. During the use, it is rotatory through the big bevel gear of little bevel gear drive earlier, adjust the jack catch abduction, then insert the pipe fitting between three jack catchs, the cover is on the depression bar, contract the antedisplacement of drive push rod in adjusting the jack catch after that, then the top of elasticity depression bar is the abduction under lever principle's effect, props the inner wall of pressing the pipe fitting, after that the jack catch contracts in continuing, the outer wall of cramping pipe fitting to formation two -way centre gripping inside and outside to the pipe fitting has not only improved centre gripping stability, has effectively avoided the pipe fitting deformation in addition.
Description
Technical field
The utility model relates to machine tool accessories technical field, especially a kind of two-way 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 is all that not only structural stability is poor, and easily makes pipe fitting be out of shape from outside one direction clamping pipe fitting.
Utility model content
Poor in order to overcome existing scroll chuck structural stability, easily make the deficiency that pipe fitting is out of shape, the utility model provides a kind of two-way type scroll chuck.
The utility model solves the technical scheme that its technical problem adopts: a kind of two-way 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 push rod is provided with depression bar, and depression bar is provided with pressing plate.
According to another embodiment of the present utility model, comprise push rod further and be connected to bottom inside claw.
According to another embodiment of the present utility model, comprising depression bar is further elastic rod, perpendicular to push rod, is rotatably connected with push rod.
According to another embodiment of the present utility model, comprise further between each depression bar and being linked into an integrated entity by supporting disk.
According to another embodiment of the present utility model, comprise pressing plate further and be rotatably connected on the top of depression bar.
The beneficial effects of the utility model are, connect a push rod in the inside bottom of every claw, and the depression bar that is rotatably connected in the front end of push rod, linked into an integrated entity by supporting disk between each depression bar, form inside and outside two-way clamping mechanism.During use, first drive bevel gear wheel to rotate by bevel pinion, regulate claw abduction; Then pipe fitting is inserted between three claws, be enclosed within depression bar; Then regulate claw to inside contract, drive pushrod advances; Then the top of elastic pressure bar abduction under the effect of lever principle, the inwall of bulging pipe fitting; Then claw continues to inside contract, and clamps the outer wall of pipe fitting, thus is formed two-way clamping inside and outside pipe fitting, not only increases clamping stability, and effectively prevent pipe fitting distortion.
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. depression bar, 7. pressing plate, 8. supporting disk in figure.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of two-way 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, and bevel pinion 3 and bevel gear wheel 4 are connected with a joggle, and claw 2 is provided with push rod 5, push rod 5 is provided with depression bar 6, and depression bar 6 is provided with pressing plate 7.Push rod 5 is connected to the bottom inside claw 2.Depression bar 6 is elastic rod, perpendicular to push rod 5, is rotatably connected with push rod 5.Linked into an integrated entity by supporting disk 8 between each depression bar 6.Pressing plate 7 is rotatably connected on the top of depression bar 6.
A push rod 5 is connected in the inside bottom of every claw 2, and the depression bar 6 that is rotatably connected in the front end of push rod 5, linked into an integrated entity by supporting disk 8 between each depression bar 6, form inside and outside two-way clamping mechanism.During use, first drive bevel gear wheel 4 to rotate by bevel pinion 3, regulate claw 2 abduction; Then pipe fitting is inserted between three claws 2, be enclosed within depression bar 6; Then regulate claw 2 to inside contract, drive push rod 5 to move forward; Then the pressing plate 7 on flexible depression bar 6 top is the inwall of fulcrum abduction, bulging pipe fitting with supporting disk 8 under the effect of lever principle; Then claw 2 continues to inside contract, and clamps the outer wall of pipe fitting, thus is formed two-way clamping inside and outside pipe fitting, not only increases clamping stability, and effectively prevent pipe fitting distortion.
