Abstract
The polygonal centering clamp is of a cylindrical structure, a polygonal hole (2) is formed in the polygonal centering clamp, and the polygonal hole (2) and the cylindrical structure are coaxially arranged; according to the size of the polygon, a corresponding cylindrical centering fixture is designed, and the polygon is processed through the cylindrical centering fixture.
Description
Technical Field
The utility model relates to a polygonal centering fixture.
Background
When the chuck is used for processing parts, the three-jaw chuck can only grasp round workpieces, so that polygonal workpieces cannot be processed, and certain limitations exist. The polygonal holes are then machined inside the cylinder by means of the cylinder, and the polygonal work pieces are then placed in the corresponding clamps for machining.
Disclosure of Invention
The utility model aims to provide a polygonal centering clamp which solves the problem of fixing and processing of polygonal workpieces. In order to achieve the purpose, the utility model adopts the following technical scheme:
the polygonal centering clamp is of a cylindrical structure, a polygonal hole is formed in the polygonal centering clamp, and the polygonal hole and the cylindrical structure are coaxially arranged; the polygonal centering fixture is also provided with a clamping notch, and the polygonal hole is communicated with the outside of the cylindrical structure through the clamping notch; the two side walls of the polygonal hole are provided with top thread holes penetrating to the outside of the cylindrical structure, and the two side top thread holes are symmetrically arranged relative to the clamping notch.
Further, each corner of the polygonal hole is provided with a circular arc-shaped avoiding hole.
Further, the polygonal holes are quadrangular or hexagonal.
Compared with the prior art, the utility model has the advantages that: according to the size of the polygon, a corresponding cylindrical centering fixture is designed, and the polygon is processed through the cylindrical centering fixture.
Drawings
The utility model will be described in more detail hereinafter on the basis of embodiments and with reference to the accompanying drawings. Wherein:
FIG. 1 is a schematic view of the polygonal centering fixture of the present utility model.
Fig. 2 is a schematic view of two polygonal holes of the polygonal centering fixture of the present utility model.
Wherein, the reference signs mean:
1. polygonal centering fixture, 2, polygonal hole, 3, clamping notch, 4, dodge hole, 5, jackscrew hole.
Detailed Description
In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings.
As shown in fig. 1 and 2, the polygonal centering fixture 1 of the utility model has an outer cylindrical structure, a polygonal hole 2 is formed in the outer cylindrical structure, and the polygonal hole 2 and the cylindrical structure of the polygonal centering fixture 1 are coaxially arranged; the polygonal centering fixture 1 is also provided with a clamping notch 3, and the polygonal hole 2 is communicated with the outside of the cylindrical structure through the clamping notch 3; each corner of the polygonal hole 2 is provided with a circular arc-shaped avoiding hole 4, and after the polygonal workpiece is placed into the polygonal centering fixture 1, the corners of the polygonal workpiece are avoided. In addition, the side walls of the two sides of the polygonal hole 2 are also provided with jackscrew holes 5 penetrating to the outside of the cylindrical structure, and the jackscrew holes 5 on the two sides are symmetrically arranged relative to the clamping notch 3.
After the polygonal machined parts are placed in the polygonal centering fixture 1, the jackscrews are inserted into the jackscrew holes 5, and the clamping notch 3 can reduce the distance at the same time when the jackscrews are used for locking, so that the machined parts are fixed firmly. The polygonal holes can be quadrilateral, hexagonal or other polygonal, and the holes can be designed according to the specific edge number of the workpiece.
The above is merely a preferred embodiment of the present utility model, and is not intended to limit the present utility model in any way. While the utility model has been described with reference to preferred embodiments, it is not intended to be limiting. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present utility model or modifications to equivalent embodiments using the methods and technical contents disclosed above, without departing from the scope of the technical solution of the present utility model. Therefore, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present utility model still fall within the scope of the technical solution of the present utility model.
Claims (3)
