Abstract
The invention discloses a lathe chuck. The lathe chuck comprises a chuck body and step type claws uniformly distributed on the chuck body, wherein lifting steps are arranged at the positions far away from one end of the chuck body on the step type claws; rotating screw rods are arranged in the step type claws; the lifting steps and the rotating screw rods are connected in a matching way by screw threads. Compared with the prior art, the lathe chuck provided by the invention has the advantages that the length can be increased by the lifting steps arranged on the claws, the firmness for clamping a workpiece is enhanced, the lathe chuck is generally used for clamping a relatively long workpiece to prevent the workpiece from falling when the workpiece is over long.
Description
Technical field
The present invention relates to a kind of lathe chuck.
Background technology
In Vehicle Processing field,, can there is certain danger in the workpiece that lathe chuck clamping is grown, because Workpiece length is long, deviation of gravity center chuck is far away, the poor stability of clamping chuck, generally needs tailstock tool to support, and has the problem easily dropping, clamping is improper, very easily landing from chuck of workpiece, causes damage, even pounds and hurts sb.'s feelings.
Summary of the invention
The technical issues that need to address of the present invention are for above-mentioned the deficiencies in the prior art, and provide a kind of firmly clamping compared with the lathe chuck of machining long workpieces.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of lathe chuck, comprise disk body of chuck, and all occupy the step claw being distributed on disk body of chuck, on described step claw, away from the position of disk body of chuck one end, lifting step is set, in step claw, rotating screw bolt is set, described lifting step is connected with rotating screw bolt threaded engagement.
On the clamping face of lifting step, rotation press strip is set.
Described lifting step is detachable.
Compared with prior art, a kind of lathe chuck of the present invention, additional lifting step on step claw, can increase the overall clamping length of chuck, for compared with the clamping of machining long workpieces, can make workpiece center of gravity more press close to the clamping position of chuck, guarantee the stability of clamping, on the clamping face of lifting step, rotation press strip is set, can further lengthen the clamping length of lifting step, optionally use, the present invention is simple in structure, there is unstable problem compared with machining long workpieces in the basic lathe chuck clamping that solves, reduce the use of tail stock, firmly under prerequisite, can improve machine spindle speed at clamping, increase work efficiency, applicability is wide.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Wherein, 1-disk body of chuck, 2-step claw, 3-lifting step, 4-rotating screw bolt, 5-rotates press strip.
The specific embodiment
Describe the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of lathe chuck of the present invention, comprise disk body of chuck 1, and all residence is distributed in the step claw 2 on disk body of chuck 1, on described step claw 2, away from the position of disk body of chuck 1 one end, lifting step 3 is set, at the interior rotating screw bolt 4 that arranges of step claw 2, described lifting step 3 is connected with rotating screw bolt 4 threaded engagement.
Rotation press strip 5 is set on the clamping face of lifting step 3.
Described lifting step 3 is detachable.
Claims (3)
