Being pressed on described annular boss by described elastic ring, described elastic ring pressurized diametrically expands and is pressed on described thin wall circular
On the medial wall of class workpiece.
It is preferred that described elastic ring is O-ring seals.
It is preferred that described elastic ring uses rubber to make.
It is preferred that the internal diameter of the external diameter of the external diameter of described annular boss, elastic ring and described thin-wall circular annular workpieces is mutually
Join.
It is preferred that the internal diameter of the external diameter of described pull bar and described through hole matches.This utility model is owing to using above skill
Art scheme, is allowed to compared with prior art, has the following advantages that and good effect:
The thin-wall circular annular workpieces light cut automatic fixture that this utility model provides, by extruding elastic ring, elastic ring
The tension force produced realizes the clamping to workpiece, and this clamp structure is simple, the workpiece light cut processing that applicable poor rigidity, intensity are weak
Using, and this method of clamping makes each point uniform force of workpiece 1, further decreases workpiece 1 and adds carrying out cutting
Deflection during work, it is ensured that the crudy of part.
Accompanying drawing explanation
In conjunction with accompanying drawing, by hereafter state detailed description, above-mentioned and other spy of the present utility model can be more clearly understood that
Seek peace advantage, wherein:

Detailed description of the invention
See the accompanying drawing illustrating this utility model embodiment, this utility model is described in more detail.But, this reality
Can realize in many different forms with novel, and should not be construed as the embodiment by herein proposing and limited.On the contrary, propose
These embodiments are to reach fully and complete disclosure, and it is new to make those skilled in the art understand this practicality completely
The scope of type.In these accompanying drawings, for clarity sake, may be exaggerated layer and the size in region and relative size.
With reference to 1-2, this utility model provides a kind of thin-wall circular annular workpieces light cut automatic fixture, by chuck body
2, the part such as pull bar 3, elastic ring 4 composition；This fixture is used for clamping thin-wall circular annular workpieces 1 and gently processes, this utility model
There is the advantage such as deflection reduced in processing.
In the present embodiment, chuck body 2 is in a disk-like structure；Certainly, in other embodiments chuck body 2 also in square
Shape or irregular shape, do not limit；The circle centre position of chuck body 2 is provided with a through hole, and through hole side surrounding sets
Being equipped with an annular boss 5, annular boss 5 is coaxially disposed with through hole, the internal diameter of preferred annular boss 5 and the internal diameter phase of through hole
With；In the present embodiment, annular boss 5 is made into integration with chuck body 2, in other embodiments, and chuck body 2 and convex annular
Platform 5 also can be separately made coaxially connected together by connector again, does not limits.
In the present embodiment, pull bar 3 is located in through hole and annular boss 5, and pull bar 3 is on one end of annular boss 5
Being provided with a friction top 6, the diameter of friction top 6 is more than the diameter of pull bar 3；At least one elastic ring 4 the most sheathed on pull bar 3, and
Elastic ring 4 is between annular boss 5 and friction top 6.The number that arranges of elastic ring 4 can be according to workpiece 1 in the present embodiment
Sizes etc., because usually determining, do not limit.
In the present embodiment, the external diameter of pull bar 3 and through hole and the internal diameter of diameter and annular boss 5 match, i.e. draw
The external diameter of bar 3 and through hole and the internal diameter of diameter and annular boss 5 be close, ensure simultaneously pull bar 3 can relative to fixture this
Body 2, annular boss 5 move axially.
In the present embodiment, the internal diameter of thin-wall circular annular workpieces 1 and the external diameter of friction top 6, the external diameter of elastic ring 4, annular
The external diameter of boss 5 matches, i.e. the external diameter of friction top 6, the external diameter of elastic ring 4, annular boss 5 external diameter should be as close possible to thin
The internal diameter of wall circle annular workpieces 1, ensures that thin-wall circular annular workpieces 1 can overlap simultaneously and is set to friction top 6, elastic ring 4, annular boss 5
On；
In the present embodiment, elastic ring uses O-ring seals, specifically can be made up of rubber elastomeric material.
The operation principle of the fixture provided with regard to this utility model below is further described, concrete:
The when that fixture using, workpiece 1 is set in friction top 6, elastic ring 4, the outside of annular boss 5, and pull bar 3 axially moves
Dynamic, friction top 6 is to chuck body 2 one side shifting, and elastic ring 4 is pressed on annular boss 5 by friction top 6, and elastic ring 4 is because being subject to
The pressure of friction top 6 produces homogeneous expansion in the radial direction so that each point uniform force of workpiece 1, thus swelling workpiece
1, thus play the effect of clamping, this clamp structure is simple, easy to operate, and the workpiece light cut being suitable for poor rigidity, intensity weak adds
Work uses；And this method of clamping makes each point uniform force of workpiece 1, further decreases workpiece 1 and is cutting
Deflection in the course of processing.
Can regulate it addition, elastic ring 4 is applied to the clamping force on workpiece 1, the swell increment of elastic ring 4 directly determines
The clamping force of thin-wall workpiece 1, and the pull stroke of pull bar 5 determines the swell increment of elastic ring 4, therefore can be drawn by regulation
The pull stroke of bar 5 changes the clamping force of thin-wall workpiece 1.
Those skilled in the art should be understood that this utility model can not take off so that other concrete forms many realize
Spirit or scope from itself.Although having been described for case study on implementation of the present utility model, it should be understood that this utility model should not limit
Be made as these embodiments, the spirit of the present utility model that those skilled in the art can define such as appended claims and
Within the scope of make and changing and modifications.
