Description
Technical field
The present invention relates to a kind of two-jaw self-centering adjustable chuck.
Background technology
Chuck is to be used for the mechanical device of clamping work pieces on the lathe, to be distributed on moving radially of movable jaw on the disk body, with the machine tool accessories of workpiece clamping and positioning.
Existing self-centering chuck generally includes three-jaw self-centering chuck and four paws self-centering chuck.The claw of these two kinds of chucks radially is installed on the disk body, and can upwards move to reach the purpose of centering synchronously in the footpath of disk body.When the outside of cylinder barrel class workpiece was not absolute circle, during with this kind gripper chuck clamping of workpieces, the center of workpiece was incorrect, can cause machining accuracy to reduce.At this moment, need each claw of adjustment separately, avoid error.This method is loaded down with trivial details and often inaccurate, and scroll chuck or chuck structure are also complicated.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, simple two-jaw self-centering adjustable chuck of feeling relieved.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of two-jaw self-centering adjustable chuck comprises chuck body, connects the keyset of described chuck body and lathe, and described chuck body is provided with the claw connecting plate, is connected the claw on the described chuck body by described claw connecting plate.Be connected with adjustable top on the described keyset by bolt; Described adjustable top comprise top, be arranged on the described bolt and with its locking nut that is complementary, be connected described top and described keyset the nut base; Reach the outside in the described adjustable top hole, the described adjustable top center that is positioned at described chuck body by described chuck body center;
Described claw comprises the adjustable claw of pair of opposing; A pair of described adjustable claw is being positioned on the described chuck on the diameter; The finger mountings that described adjustable claw comprises thimble, be vertically connected on connecting rod on the described thimble, be complementary with described claw connecting plate, described connecting rod is fixed on the nut on the described finger mountings, described finger mountings is fixed on the described claw connecting plate;
The described adjustable top centerline that is positioned at a pair of described adjustable claw.
Preferably, described locking nut is provided with handle.
Preferably, described finger mountings is " L " shape, and first end of the finger mountings of described " L " shape is connected on the described claw connecting plate, is fixedly connected with described connecting rod on second end.
Preferably; Described thimble has two states with respect to described finger mountings; Described thimble can be fixedly connected on a side of described finger mountings by described nut and described connecting rod, and the back of also can overturning is fixedly connected on the opposite side of described finger mountings by described nut and described connecting rod.
Related content in the technique scheme is explained as follows:
In the such scheme, adjustable top being used for positions the workpiece that clamps.On the centre of gyration of cylinder barrel class workpiece centre bore is arranged, adjustable top this centre bore that promptly utilizes positions workpiece.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1, because the present invention is provided with adjustable toply, can use it that cylinder barrel class part is positioned, simple in structure, easy to use.
2, because the present invention adopts a pair of adjustable claw clamping work pieces, simple in structure, but the altitude range of the workpiece of clamping is bigger.
