Abstract
The invention discloses a chuck for a machine tool. The chuck for the machine tool comprises a base and an annular installation base. The annular installation base is arranged on the surface of the base; two symmetrical sliding chutes are arranged on the bottom face of the base; the base is placed on two sliding rails corresponding to the sliding chutes through the sliding chutes; three hydraulic installation holes are formed in the annular installation base along a circumferential direction of the annular installation base, and are distributed in an equilateral triangle shape; hydraulic rods are arranged in the three hydraulic installation holes; output shafts of the three hydraulic rods face to the center of the annular installation base; and a clamping plate is connected to end parts, far away from the annular installation base, of the output shafts of the three hydraulic rods. When the chuck for the machine tool is used, an object is clamped through the hydraulic rods, the hydraulic rods have the functions of stability in output and large clamping force, and the device is simple in structure and stable and firm to clamp, and solves the problem that a workpiece deviates frequently since a traditional chuck for the machine tool cannot clamp a casting piece firmly, so that the casting piece is loosened.
Description
Technical field
The present invention relates to machine chuck technical field, specially a kind of chuck of machine tool.
Background technology
Traditional chuck is typically made up of chuck body, movable jaw and claw drive mechanism part, is a kind of
Using moving radially for the movable jaw being distributed on chuck body, Workpiece clamping and the machine tool accessories of positioning.
There is through hole in chuck body center, will pass through workpiece.Chuck is typically mounted on lathe, cylindrical grinder and inner circle
Used on grinding machine, can also coordinated with various indexing means, for milling machine and drilling machine.In process,
As lathe spindle drives casting to rotate at a high speed, the cutter on knife rest is added also while cutting casting
Motion, traditional claw occurs that clamping workpiece is insecure, and chuck probably presss from both sides loosely casting, often
Cause workpiece variation, so that the phenomenon for loosening occurs in casting, influence the machining accuracy of casting, therefore,
It is proposed that a kind of chuck of machine tool.
The content of the invention
It is an object of the invention to provide a kind of chuck of machine tool, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the present invention provides following technical scheme：A kind of chuck of machine tool, including base
With annular mounting seat, annular mounting seat is arranged on susceptor surface, and base end face is provided with two symmetrical cunnings
Groove, base is placed on two slide rails corresponding with chute by chute.
Along its circumferentially disposed three hydraulic installalion hole in annular mounting seat, and three hydraulic installalion holes are in equilateral
Triangle-Profile, is provided with hydraulic stem, the equal court of output shaft of three hydraulic stems in three hydraulic installalion holes
To annular mounting seat center, three output shafts of hydraulic stem are respectively connected with card away from the end of annular mounting seat
Plate.
Preferably, clamp is circular arc, when three hydraulic stems are in most long, now three circular arc
Card is mutually spliced into annular soon.
Preferably, annular is installed seat supports by the side of base two by pole.
Preferably, pole is structure as a whole with annular mounting seat.
Compared with prior art, the beneficial effects of the invention are as follows：The chuck of machine tool when in use, passes through
Hydraulic stem steps up object, and hydraulic stem has stabilization output and the big function of gripping strength, the apparatus structure
Simply, clamp stabilization and firmly, solving traditional machine chuck may press from both sides loosely casting, when often result in
Workpiece variation, so that the problem for loosening occurs in casting.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1st, base, 2, slide rail, 3, pole, 4, annular mounting seat, 5, hydraulic stem, 6,
Clamp, 7, hydraulic installalion hole.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the invention, and
It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out the every other embodiment obtained under the premise of creative work, belong to the scope of protection of the invention.
Fig. 1 is referred to, the present invention provides a kind of technical scheme：A kind of chuck of machine tool, including the He of base 1
Annular mounting seat 4, annular mounting seat 4 is arranged on the surface of base 1, and 1 liang of side of base will by pole 3
Annular mounting seat 4 is supported, and pole 3 is structure as a whole with annular mounting seat 4, and pole 3 can allow annular
More stablize between mounting seat 4 and base 1, the bottom surface of base 1 is provided with two symmetrical chutes, base 1
It is placed on two slide rails 2 corresponding with chute by chute, dragging base 1 can make the device edge
Slide rail movement, the distance with machine tool is widened.
It is in along its circumferentially disposed three hydraulic installalion hole 7, and three hydraulic installalion holes 7 in annular mounting seat 4
Equilateral triangle is distributed, and is provided with hydraulic stem 5 in three hydraulic installalion holes 7, three hydraulic stems 5 it is defeated
, towards the annular center of mounting seat 4, three output shafts of hydraulic stem 5 are away from annular mounting seat 4 for shaft
End is respectively connected with clamp 6, and clamp 6 is circular arc, when three hydraulic stems 5 are in most long, now
Three circular arc cards fast 6 are mutually spliced into annular.When in use, object is stepped up by hydraulic stem 5,
Hydraulic stem 5 has stabilization output and the big function of gripping strength, and the apparatus structure is simple, clamping stabilization and
Firmly.
Although an embodiment of the present invention has been shown and described, for one of ordinary skill in the art
Speech, it is possible to understand that these embodiments can be carried out without departing from the principles and spirit of the present invention
Various changes, modification, replacement and modification, the scope of the present invention are limited by appended claims and its equivalent
It is fixed.
