Abstract

The invention discloses a jig for an annular work piece. The jig comprises a pedestal, a conical extrusion head and an elastic collet, wherein the conical extrusion head is fixedly arranged on the pedestal; the elastic collet is positioned at the upper part of the conical extrusion head; a clamping slot is formed in the outer surface of the elastic collet; a conical hole is formed in the central position of the lower part of the elastic collet; the vortex angle of the conical hole is smaller than that of the conical extrusion head. As a whole, the jig disclosed by the invention has the advantages of being simple in structure, convenient to operate and capable of improving the machining precision and the machining quality of the annular work piece.

Description

A kind of tool of annular workpieces
Technical field
The invention belongs to machinery tool field, relate to the tool of a kind of annular workpieces.
Background technology
Tool refers to be used for fixing processing object during machine-building, is allowed to occupy correct position, to accept construction or the device of detection.When machine tool processing workpiece, drawing specifies in order to make the surface of workpiece to reach dimensions, geometry and with the technology requirements such as the relative-position error on other surfaces, workpiece should be positioned before processing, clamp.Tool of the prior art clamp workpiece time, easy run-off the straight and shift phenomenon, reduce the precision of processing, have impact on the quality of processing.
Summary of the invention
It is an object of the invention to provide the tool of a kind of annular workpieces, this jig structure is simple, it is possible to increase the precision of ring-shaped work pieces processing, has high use value.
The object of the present invention is achieved like this: the tool of a kind of annular workpieces, including base, tapered squeezing head, collet, tapered squeezing head it is fixed with on described base, described collet is positioned at the top of tapered squeezing head, described collet upper outer surface is provided with draw-in groove, and the lower central position of described collet has bellmouth.
The drift angle of described bellmouth is less than the drift angle of tapered squeezing head.
The beneficial effect comprise that: the bellmouth of collet provides enough spaces, only draw-in groove inwardly need to be extruded during use, ring-shaped work pieces just can be enclosed within the draw-in groove of collet, and collet utilizes the elasticity of self can be returned to original state, and part has just been enclosed within chuck.Then the bellmouth of collet being directed at tapered squeezing head to press down on, the bellmouth of collet gradually expands the squeezing action playing workpiece, is securely fixed by workpiece.Add man-hour, machine can be good at process part, this simple in construction, easy to operate, substantially increase the crudy of part.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the present invention.
In figure: 1, base 2, tapered squeezing 3, collet 4, draw-in groove 5, bellmouth.
Detailed description of the invention
Below in conjunction with the accompanying drawings to embodiments of the invention further instruction.
Embodiment 1
As shown in Figure 1, a kind of tool of annular workpieces, including base 1, tapered squeezing 2, collet 3, it is fixed with tapered squeezing 2 on described base 1, described collet 3 is positioned at the top of tapered squeezing 2, described collet 3 upper outer surface is provided with draw-in groove 4, and the lower central position of described collet 3 has bellmouth 5.
The drift angle of described bellmouth 5 is less than the drift angle of tapered squeezing 2.
The present invention is in use: the tool of a kind of annular workpieces, tapered squeezing head is securely fastened on base, annular workpieces on overlapping on collet, then bellmouth is directed at tapered squeezing head, constantly collet is pressed downward against, collet is big by the support of tapered squeezing head during pressure down, thus is fixed by workpiece firmly.
Generally, the present invention has simple in construction, easy to operate, improves machining accuracy and the advantage of crudy of annular workpieces.

Claims (2)

1. the tool of an annular workpieces, including base, tapered squeezing head, collet, it is characterized in that: on described base, be fixed with tapered squeezing head, described collet is positioned at the top of tapered squeezing head, described collet upper outer surface is provided with draw-in groove, and the lower central position of described collet has bellmouth.
The tool of a kind of annular workpieces the most according to claim 1, it is characterised in that: the drift angle of described bellmouth is less than the drift angle of tapered squeezing head.
