Description
Technical field
The present invention relates to jig Design technical field, be specifically related to a kind of thin-wall circular annular workpieces light cut automatic fixture.
Background technology
Workpiece is when carrying out the processing such as cutting, it is necessary to is fixed and can be easy to processing, it is common to use clip handles and is fixed；But due to weak in thin wall work-piece poor rigidity, intensity, clamp according to existing fixture, very easily make workpiece work in-process deform so that the form and position tolerance of workpiece increases, and not easily ensures the crudy of part.Therefore, clamping problems during processing thin-walled parts is a thorny job.
Summary of the invention
For the problem in background technology, the invention provides a kind of thin-wall circular annular workpieces light cut automatic fixture, including:
Chuck body, is provided with a through hole, and the surrounding of described through hole side is provided with an annular boss；
Pull bar, is located in described through hole, and one end of described pull bar is provided with friction top, and is positioned at the side of described annular boss；
At least one elastic ring, is set on described pull bar, and between described friction top and described annular boss；Thin-wall circular annular workpieces is enclosed within the outside of described friction top, elastic ring, annular boss, described pull bar moves axially, described elastic ring is pressed on described annular boss by described friction top, and described elastic ring pressurized diametrically expands on the medial wall being pressed on described thin-wall circular annular workpieces.
It is preferred that described elastic ring is O-ring seals.
It is preferred that described elastic ring adopts 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 matches.
It is preferred that the internal diameter of the external diameter of described pull bar and described through hole matches.Due to the fact that the above technical scheme of employing, so as to compared with prior art, have the following advantages that and good effect:
Thin-wall circular annular workpieces light cut automatic fixture provided by the invention, by extruding elastic ring, the tension force that elastic ring produces realizes the clamping to workpiece, this clamp structure is simple, the workpiece light cut processing use that applicable poor rigidity, intensity are weak, and this method of clamping makes each point uniform force of workpiece 1, further decreases workpiece 1 deflection in carrying out cutting process, it is ensured that the crudy of part.

Detailed description of the invention
Referring to the accompanying drawing illustrating the embodiment of the present invention, the present invention is described in more detail.But, the present invention can realize in many different forms, and should not be construed as by restriction of the embodiment of proposition at this.On the contrary, it is proposed to these embodiments are to reach fully and complete disclosure, and make those skilled in the art understand the scope of the present invention completely.In these accompanying drawings, for clarity sake, it is possible to be exaggerated size and the relative size in layer and region.
With reference to 1-2, the invention provides a kind of thin-wall circular annular workpieces light cut automatic fixture, be made up of parts such as chuck body 2, pull bar 3, elastic rings 4；This fixture is used for clamping thin-wall circular annular workpieces 1 and gently processes, and the present invention has the advantages such as the deflection in minimizing processing.
In the present embodiment, chuck body 2 is in a disk-like structure；Certainly, chuck body 2 is also rectangular in other embodiments or irregular shape, does not limit herein；The circle centre position of chuck body 2 is provided with a through hole, and through hole side surrounding is provided with an annular boss 5, and annular boss 5 and through hole are coaxially disposed, it is preferred that the internal diameter of annular boss 5 is identical with the internal diameter of through hole；In the present embodiment, annular boss 5 and chuck body 2 are made into integration, in other embodiments, chuck body 2 and annular boss 5 also can separately made again through connector coaxially connected together with, do not limit herein.
In the present embodiment, pull bar 3 is located in through hole and annular boss 5, and pull bar 3 is provided with a friction top 6 on one end of annular boss 5, and the diameter of friction top 6 is more than the diameter of pull bar 3；Also at least one elastic ring 4 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 according to size of workpiece 1 etc. because usually determining, can not limit herein in the present embodiment.
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, namely the external diameter of pull bar 3 and through hole and the internal diameter of diameter and annular boss 5 be close, guarantee pull bar 3 can move axially relative to chuck body 2, annular boss 5 simultaneously.
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 boss 5 external diameter match; namely the external diameter of friction top 6, the external diameter of elastic ring 4, annular boss 5 external diameter should as close possible to the internal diameter of thin-wall circular annular workpieces 1, guarantee thin-wall circular annular workpieces 1 can overlap and be set on friction top 6, elastic ring 4, annular boss 5 simultaneously；
In the present embodiment, elastic ring adopts O-ring seals, specifically can be made up of rubber elastomeric material.
Operation principle with regard to fixture provided by the invention is further described below, concrete:
Time fixture uses, workpiece 1 is set in the outside of friction top 6, elastic ring 4, annular boss 5, pull bar 3 moves axially, 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, elastic ring 4 produces homogeneous expansion in the radial direction because of the pressure being subject to friction top 6, make each point uniform force of workpiece 1, thus swelling workpiece 1, thus playing the effect of clamping, this clamp structure is simple, easy to operate, the workpiece light cut processing use that applicable poor rigidity, intensity are weak；And this method of clamping makes each point uniform force of workpiece 1, further decreases workpiece 1 deflection in carrying out cutting process.
Additionally, elastic ring 4 is applied to the clamping force on workpiece 1 and can regulate, 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, the clamping force of thin-wall workpiece 1 therefore can be changed by the pull stroke of adjusting yoke 5.
Those skilled in the art should be understood that the present invention can be implemented without departing from the spirit or scope of itself with other concrete forms many.Although having been described for the case study on implementation of the present invention, it should be understood that the present invention should not be limited to these embodiments, those skilled in the art can change and modifications as made within the spirit and scope of the present invention that appended claims defines.
