Abstract
The utility model relates to a fixture for machining an ultra-deep stepped hole. The fixture for machining the ultra-deep stepped hole comprises a cylindrical insulation core rod (1) arranged inside a through hole of a workpiece (5), wherein the two ends of the insulation core rod (1) extend out of the through hole, the upper extending end of the insulation core rod (1) is sleeved with an annular electrode (2), the circle center of the insulation core rod (1) and the circle center of the electrode (2) are coincident, the lower extending end of the insulation core rod (1) is sleeved with a fixing block (3), the upper end of the electrode (2) is clamped on a rotating head (4), and the electrode (2) is driven by the rotating head (4) to move downwards along the insulation core rod (1). By means of the mode, the fixture for machining the ultra-deep stepped hole can ensure the size precision of machining of the ultra-deep stepped hole, mainly the butt joint precision of two holes of the stepped hole.
Description
Technical field
The utility model relates to the processing jig technical field, particularly a kind of super dark shoulder hole processing special fixture.
Background technology
Shoulder hole refers to that endoporus is the hole by two kinds of different-diameters, the hole of continuing under same axle center and forming together.If aperture, two kinds, such hole is not very dark relatively easy processing, just be difficult to processing if wherein there is its aspect ratio of a kind of aperture to surpass 100: 1, difficult point just is: how to guarantee the concentricity in two kinds of apertures and the two kinds of apertures axiality with respect to external diameter.
The utility model content
The purpose of this utility model is the defect that exists in existing technology in order to solve, and a kind of super dark shoulder hole processing special fixture is provided, and can guarantee the dimensional accuracy of deep hole shoulder hole processing, is mainly shoulder hole two hole merging precisions.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of super dark shoulder hole processing special fixture, comprise the cylindrical insulation mandrel that is arranged in workpiece through-hole, through hole is all stretched out at the two ends of described insulation mandrel, on it, external part outside cover has an annular electrode, described insulation mandrel overlaps with the center of circle of electrode, and the lower external part outside cover of described insulation mandrel has a fixed block.
As further improvement, the upper end clamping of described electrode on swivel head, and moves downward along insulation mandrel under the drive of swivel head.
The beneficial effects of the utility model are: can guarantee the dimensional accuracy of deep hole shoulder hole processing, be mainly shoulder hole two hole merging precisions.
Description of drawings
Further illustrate the utility model below in conjunction with accompanying drawing and case study on implementation.
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1, insulation mandrel, 2, electrode, 3, fixed block, 4, swivel head, 5, workpiece.
The specific embodiment
For making, architectural feature of the present utility model and the effect reached are had a better understanding and awareness, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
In figure, a kind of super dark shoulder hole processing special fixture, comprise the cylindrical insulation mandrel 1 that is arranged in workpiece 5 through holes, through hole is all stretched out at the two ends of described insulation mandrel 1, on it, external part outside cover has an annular electrode 2, described insulation mandrel 1 overlaps with the center of circle of electrode 2, and the lower external part outside cover of described insulation mandrel 1 has a fixed block 3.
The upper end clamping of described electrode 2 on swivel head 4, and moves downward along insulation mandrel 1 under the drive of swivel head 4.
The course of work of the present utility model is as follows: first by aperture thinner in two kinds of apertures, workpiece 5 is punched, then selected the insulation mandrel 1 that is complementary with this aperture to penetrate in this hole, bottom is fixed.Select the electrode 2 that adapts with gross porosity, be set to the outside of this insulation mandrel 1 and clamping to swivel head, add man-hour insulation mandrel 1 motionless, only have the electrode 2 of outside cover to move downward and process along insulation mandrel 1, so just effectively guaranteed the concentricity in two kinds of apertures.Axiality depends on the axiality than pore, and this part utilizes and guarantees the axiality technology, can guarantee in tolerance fully.
Compared with prior art, the utility model has the advantages that: can guarantee the dimensional accuracy of deep hole shoulder hole processing, be mainly shoulder hole two hole merging precisions.
In sum, it is only preferred embodiment of the present utility model, not be used for limiting the scope that the utility model is implemented, all equalizations of according to the described shape of the utility model claim scope, structure, feature and spirit, doing change and modify, and all should be included in claim scope of the present utility model.
Claims (2)
