Abstract
The invention discloses a chuck. The chuck comprises a circular chuck body and a plurality of circular-arc-shaped clamping jaws, wherein a plurality of guide rails are mounted on the chuck body; a locking nut is mounted on each guide rail; a guide block is mounted on the outer arc of each clamping jaw; each guide block is inserted into the corresponding guide rail; a cushion is mounted on the inner arc of each clamping jaw; each clamping jaw has a left-right structure, and the left and right parts of each clamping jaw are connected through a spring return device. In the mode, the chuck is simple in structure and convenient to use; due to the fact that the cushion is mounted on each clamping jaw, clamp marks cannot be generated in the machining process of various shaft parts, and the accuracy of the machined parts is guaranteed.
Description
Technical field
The present invention relates to field of electromechanical technology, particularly relate to a kind of chuck.
Background technology
Chuck lathe is used for the mechanical device of clamping work pieces, and utilize the claw be distributed on chuck body, by Workpiece clamping and location, chuck is generally made up of chuck body, movable jaw and claw driving mechanism 3 part.Chuck body diameter is minimum is 65 millimeters, maximumly reaches 1500 millimeters, and there are through hole in central authorities, so that by workpiece or bar; There is cylindrical or short taper profile structure at back, directly or be connected by ring flange and machine tool chief axis end.
But there is a lot of problem in current chuck, such as can not clamp workpiece well very soon in operation, workpiece clamp loosely, there is the sliding phenomenon of pine in workpiece, in addition, carries out adding man-hour for axial workpiece or the part that there is curved surface, because the clamping part of the claw of existing chuck is planar structure, making above-mentioned part like this after machining, easily there is catcher mark in clamping part, thus affects the precision of part.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of chuck.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of chuck, comprising:
One chuck body, described chuck body is circular, described chuck body is provided with some guide rails, described guide rail is provided with locking nut;
Some claws, described claw is circular arc, and described claw outer arc is provided with guide block, described guide block inserts in described guide rail, the inner arc of described claw is provided with cushion pad, and described claw is divided into tiled configuration, and left and right two parts of described claw are connected by spring return function device.
In a preferred embodiment of the present invention, described guide block matches with described guide rail.
In a preferred embodiment of the present invention, the quantity of described guide rail is identical with the quantity of described claw.
The invention has the beneficial effects as follows: a kind of chuck of the present invention, this chuck structure is simple, easy to use, claw is provided with cushion pad, for the processing of all kinds of axial workpiece, can not produces catcher mark, ensure that the precision of part to be processed.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of chuck of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, chuck body; 2, guide rail; 3, claw; 4, locking nut; 5, guide block; 6, cushion pad; 7, spring return function device.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises: a kind of chuck, comprising:
One chuck body 1, described chuck body 1 is circular, and described chuck body 1 is provided with some guide rails 2, and described guide rail 2, for the movement of described claw 3, conveniently regulates the position of object.
Described guide rail 2 is provided with locking nut 4, by tightening described locking nut 4, makes described locking nut 4 compress described guide block 2, thus described claw 3 is positioned.
Some claws 3, described claw 3 is circular arc, and the quantity of described guide rail 2 is identical with the quantity of described claw 3, and the quantity of guide rail 2 described in the present invention and described claw 3 is 2.
Described claw 3 outer arc is provided with guide block 5, and described guide block 5 inserts in described guide rail 2, and described guide block 5 matches with described guide rail 2, and described guide block 5 slides in described guide rail 2, and described claw 3 can be regulated.
The inner arc of described claw 3 is provided with cushion pad 6, and described cushion pad 6 makes, to producing catcher mark the man-hour that adds of all kinds of axial workpiece, to ensure that the precision of part to be processed.
Described claw 3 is divided into tiled configuration, left and right two parts of described claw 3 are connected by spring return function device 7, by described spring return function device 7, the distance between described claw 3 liang of pawls can be regulated, can slowly open described claw 3 according to active force during contact work piece, make its part to be processed of more fitting.
Compared with prior art, a kind of chuck of the present invention, this chuck structure is simple, easy to use, claw is provided with cushion pad, for the processing of all kinds of axial workpiece, can not produces catcher mark, ensure that the precision of part to be processed.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
