Abstract
The utility model discloses the grinding and polishing that a kind of its screw mandrel has good stability and bore serial fixture.Comprise clamp body, screw mandrel and this screw mandrel is carried out to the plane bearing of axial restraint, also comprise radial fixing device, described screw mandrel is also arranged on the end cap on clamp body by this radial fixing device, between radial fixing device and end cap, is provided with sealing gasket.Serial fixture is bored in this grinding and polishing has also increased the structure of radial fixing device on the basis that adopts plane bearing, thereby has increased the radial stability of screw mandrel, makes screw mandrel have good stability, has effectively avoided screw mandrel to rock.
Description
Technical field
The utility model belongs to the technical field of polished machine, specifically relates to a kind of grinding and polishing and bores serial fixture.
Background technology
Aspect screw mandrel assembling, the only clamping to screw mandrel by plane bearing of serial fixture is bored in grinding and polishing in the market, so screw mandrel has good stability in the axial direction, and the stability Shortcomings of radial direction.
Summary of the invention
The purpose of this utility model is to provide the grinding and polishing that a kind of its screw mandrel has good stability and bores serial fixture.
The purpose of this utility model is achieved in that a kind of grinding and polishing bores serial fixture, comprise clamp body, screw mandrel and this screw mandrel is carried out to the plane bearing of axial restraint, also comprise radial fixing device, described screw mandrel is also arranged on the end cap on clamp body by this radial fixing device, between radial fixing device and end cap, is provided with sealing gasket.
On the basis of such scheme and as the preferred version of such scheme: described radial fixing device is described journal bearing, and the inner ring of this journal bearing is connected with screw mandrel, and the outer ring of journal bearing is connected with bearing block, and bearing block is fixedly connected with end cap.
On the basis of such scheme and as the preferred version of such scheme: described bearing block is fixed on end cap by screw.
On the basis of such scheme and as the preferred version of such scheme: described journal bearing is needle bearing or ball bearing.
On the basis of such scheme and as the preferred version of such scheme: described radial fixing device is copper sheathing.
On the basis of such scheme and as the preferred version of such scheme: also comprise seal closure assembly, sealing shade assembly is enclosed within on the end of screw mandrel, seal closure assembly covers in the outside of plane bearing, and the two ends of seal closure assembly form and are sealed and matched with clamp body, screw mandrel respectively.
The utility model compared to existing technology outstanding and useful technique effect is:
1, serial fixture is bored in grinding and polishing of the present utility model, has also increased the structure of radial fixing device, thereby increased the radial stability of screw mandrel on the basis that adopts plane bearing, makes screw mandrel have good stability, has effectively avoided screw mandrel to rock.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of specification in serial fixture is bored in grinding and polishing of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1;
Serial fixture is bored in the grinding and polishing that the present embodiment provides, and comprises clamp body 1, plane bearing 3, screw mandrel 2 and radial fixing device.Wherein, plane bearing carries out axial restraint to this screw mandrel, for assembling and the prior art of plane bearing, is as good as.In the present embodiment, using journal bearing 4 as radial fixing device.The inner ring of this journal bearing 4 is connected with screw mandrel 2, and the outer ring of journal bearing 4 is connected with bearing block 5, and bearing block 5 is fixedly connected with the end cap 6 on clamp body 1.Between journal bearing 4 on the every one end of screw mandrel and end cap 6, be provided with sealing gasket 7.In the present embodiment, journal bearing 4 can be needle bearing, can be also ball bearing.This fixture makes screw mandrel to form and to be rotatably connected with respect to clamp body by journal bearing, guaranteed screw mandrel with respect to clamp body in stability radially.Be understandable that, plane bearing makes screw mandrel have in the axial direction good stability, and journal bearing makes screw mandrel have in the radial direction good stability.
In the present embodiment, described bearing block 5 is fixed on end cap 6 by screw.Specifically, at the screw of described clamp body 1, screw is assemblied on this screw, and the end of screw presses closer on described bearing block 5.
Radial fixing device can also be copper sheathing.
In order to prevent that the butter in clamp body from flowing out, this fixture can also be provided with seal closure assembly, sealing shade assembly is enclosed within on the end of screw mandrel, and seal closure assembly covers in the outside of plane bearing, and the two ends of seal closure assembly form and are sealed and matched with clamp body, screw mandrel respectively.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
