Abstract
The invention discloses a clamp used for fixing a shaft part. The clamp comprises a clamp body. One end of the clamp body is provided with a connecting part connected with a machine tool head frame, and the middle portion of the clamp body is provided with a through hole coaxial with the axis of the clamp body. A limiting block provided with a key groove inserted in the shaft part is arranged on the inner side of the end, away from the connecting part, of the clamp body. When the clamp is used, the clamp body is firstly fixed to the machine tool head frame, meanwhile, the through hole can contain one tip, when the shaft part stretches in the through hole from the end, away from the connecting part, of the clamp body to make contact with the tip, axial positioning of the shaft part can be achieved, meanwhile, rotation of the shaft part can be limited through the limiting block, the limiting block can abut against the other end of the shaft part through another tip, and therefore the shaft part can be machined. Thus, when a batch of shaft parts are machined, the shaft parts only need to stretch in the through hole of the clamp body, and then the clamp parts are clamped to be machined; and therefore the clamping efficiency is high, the labor intensity of workers is lowered, and the production efficiency is improved.
Description
Technical field
The present invention relates to field of fixtures, more particularly to a kind of fixture for fixed shaft.
Background technology
In the prior art, it is main when processing shorter or required precision axial workpiece not high (being referred to as shaft member herein)
Will to being fixed by scroll chuck, when part more long is processed, it is necessary to two axial directions of top limitation axle, while
The rotation of axle is realized by heart carrier for bolt and driver plate.
But current heart carrier for bolt needs that heart carrier for bolt is fixed on one end of axle manually, then again that axle is top by two
Hold out against, rotated by driving driver plate, and then drive heart carrier for bolt to rotate, so that axle is realized rotating, and then to realize adding for axle
Work.Therefore its clamping process is not only cumbersome, and is difficult clamping, and then causes that operating efficiency is relatively low.
Therefore, how a kind of fixture that can realize shaft member quick-clamping is provided, is that those skilled in the art are badly in need of solving
Technical problem.
The content of the invention
It is an object of the invention to provide a kind of fixture for fixed shaft, axial workpiece clamping can be effectively solved numerous
It is trivial, the problems such as inefficiency.
In order to solve the above technical problems, the invention provides following technical scheme：
A kind of fixture for fixed shaft, including：Chuck body, one end of the chuck body is provided with and machine tool headstock
The through hole with its own axis coaxle is provided with the middle part of the connecting portion of connection, the chuck body, in the chuck body away from
The limited block of the keyway being provided with the inside of one end of the connecting portion in insertion shaft member.
Preferably, the limited block is the key cooperated with the keyway, and it is described that the chuck body is provided with receiving
The chamber of key, is provided with the spring for being pushed against the key in the keyway in the chamber.
Preferably, it is provided with the guide part for being easy to one end of the shaft member to stretch at the top of the key.
Preferably, the guide part is the convex-shaped arc surface at the top for being arranged on the key.
Preferably, the guide part is the inclined-plane at the top for being arranged on the key.
Preferably, the connecting portion is flange, and the flange is provided with multiple connecting holes, multiple connecting hole edges
The circumference of the flange is uniformly distributed.
Compared with prior art, above-mentioned technical proposal has advantages below：
A kind of fixture for fixed shaft provided by the present invention, including：Chuck body, one end of chuck body is provided with
The through hole with its own axis coaxle is provided with the middle part of connecting portion, chuck body with machine tool headstock connection, it is remote in chuck body
The limited block of the keyway being provided with the inside of one end of connecting portion in insertion shaft member.
Using the present invention provide fixture when, first chuck body is fixed on machine tool headstock by connecting portion, at the same folder
Tool body in the middle part of through hole can accommodate one it is top, during shaft member is stretched into through hole from the one end in chuck body away from connecting portion
During with this top contact, the axially position of shaft member can be realized, while the rotation of shaft member can be limited by limited block, then passed through
Another top other end for withstanding on shaft member, is rotated by machine tool headstock band rotation connection, and then in the presence of limited block, band
Moving axis part is rotated, you can shaft member is processed.Therefore when a collection of shaft member is processed, only shaft member need to be stretched into chuck body
In through hole in, then shaft member is clamped and can be processed, therefore clamping efficiency is higher, and the work for reducing staff is strong
Degree, and then improve production efficiency.
Brief description of the drawings
In order to illustrate more clearly of technical scheme of the invention or of the prior art, below will be to embodiment or prior art
The accompanying drawing to be used needed for description is briefly described, it should be apparent that, drawings in the following description are more of the invention
Embodiment, for those of ordinary skill in the art, on the premise of not paying creative work, can also be attached according to these
Figure obtains other accompanying drawings.
The kind that Fig. 1 is provided by a kind of specific embodiment of the invention is used for the main view sectional structure of the fixture of fixed shaft
Schematic diagram；
Fig. 2 regards structural representation by the kind that a kind of specific embodiment of the invention is provided for the right side of the fixture of fixed shaft
Figure.
Reference is as follows：
1 is chuck body, and 11 is flange, and 111 is connecting hole, and 12 is through hole, and 2 is key, and 3 is spring
Specific embodiment
Just as described in the background section, axial workpiece is processed by heart carrier for bolt mainly at present, not only loads and unloads axle
Part inconvenience, and operating efficiency is relatively low.
On the basis of based on the studies above, a kind of fixture for fixed shaft is the embodiment of the invention provides, by machine
Bed head frame band rotation connection is rotated, and then in the presence of limited block, drives shaft member to be rotated, you can be added to shaft member
Work.Therefore when a collection of shaft member is processed, shaft member need to be only stretched into the through hole in chuck body, then shaft member is clamped and can entered
Row processing, therefore clamping efficiency is higher, reduces the labour intensity of staff, and then improve production efficiency.
In order that the above objects, features and advantages of the present invention can become apparent it is understandable, below in conjunction with the accompanying drawings to this hair
Bright specific embodiment is described in detail.
Elaborate detail in order to fully understand the present invention in the following description.But the present invention can with it is various not
