Description

A kind of turning attachment
Technical field:
The utility model relates to a kind of turning attachment.
Background technology:
At present, on lathe, during processing work, generally use chuck or various power clamp head-clamp clamping of workpieces, the complex structure of chuck or power chuck, cost is big, uses also comparatively loaded down with trivial detailsly, and it is also lower to add the efficient in man-hour, the effect after the influence processing.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, and a kind of simple in structure, easy to use, a kind of turning attachment of saving cost, increasing work efficiency is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of turning attachment, comprise circular support, be fixedly connected with the columniform body of vertical setting on the support, the bottom of body interior is provided with columniform first hole that vertically is provided with, be provided with spring in first hole, the top of body interior is provided with second hole that has tapering that vertically is provided with, first hole communicates with second hole and forms a through hole, be provided with chuck in the through hole, chuck is partly formed by the cylindrical part that is complementary with first hole with the open circles taper that second hole is complementary, the cylindrical portion of chuck is placed in first hole and places on the spring, the outer surface of the cylindrical part of chuck is provided with the keyhole of vertical setting, the lower, transverse of body is inserted with set screw, the head of set screw places keyhole, the open circles taper of chuck partly places in second hole, evenly is provided with a plurality of openings in the open circles taper part of chuck.
Further improvement of the utility model is: the tapering α in conical second hole is 60-63 °.
Further improvement of the utility model is: opening is three, and the angle between two adjacent openings is 120 °.
The utility model compared with prior art has the following advantages: the utility model only need be used the tailstock top tight workpiece, just can make the utility model clamping work pieces, guaranteed the processing of workpiece on lathe, improve operating efficiency greatly, after the process finishing, unclamped tailstock, workpiece just can eject chuck automatically, easy to operate, the effect height, cost is low.
Description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the cutaway view of A-A among Fig. 2;
Fig. 4 is the internal view of body.
Number in the figure: 1-support, 2-body, 3-first hole, 4-spring, 5-second hole, 6-chuck, 7-keyhole, 8-set screw, 9-opening.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of embodiment of a kind of turning attachment of the utility model as Fig. 1 to Fig. 4, comprise circular support 1, be fixedly connected with the columniform body 2 of vertical setting on the support 1, the bottom of body 2 inside is provided with columniform first hole 3 that vertically is provided with, be provided with spring 4 in first hole 3, the top of body 2 inside is provided with second hole 5 that has tapering that vertically is provided with, first hole 3 communicates with second hole 5 and forms a through hole, be provided with chuck 6 in the through hole, chuck 6 is partly formed by the cylindrical part that is complementary with first hole 3 with the open circles taper that second hole 5 is complementary, the cylindrical portion of chuck 6 is placed in first hole 3 and places on the spring 4, the outer surface of the cylindrical part of chuck 6 is provided with the keyhole 7 of vertical setting, the lower, transverse of body 2 is inserted with set screw 8, the head of set screw 8 places keyhole 7, set screw 8 can prevent that chuck 6 is in body 2 inner rotations, the open circles taper of chuck 6 partly places in second hole 5, evenly be provided with a plurality of openings 9 in the open circles taper part of chuck 6, general opening 9 the bests are three, and the angle between two adjacent openings 9 is 120 °.The tapering α in conical second hole 5 is 60-63 °, this angle be greater than chuck 6 open circles taper part from the locking angle, when guaranteeing that anchor clamps in the raw, the open circles taper part of chuck 6 is for open state, and it is a cylindrical hole that the open circles taper of chuck 6 partly surrounds boring place, back.
The utility model is fixed on the main shaft of lathe by support 1, when anchor clamps in the raw the time, because the elastic force of spring 4 self, the open circles taper part of chuck 6 is for open state, fill in the chuck 6 and work as workpiece, and under the promotion of tailstock, promote chuck 6, chuck 6 holddown springs 4, the open circles taper of chuck 6 is partly tightened up, and workpiece tightly can be clamped.The utility model only need be used the tailstock top tight workpiece, just can make the utility model clamping work pieces, has guaranteed the processing of workpiece on lathe, has improved operating efficiency greatly, after the process finishing, unclamp tailstock, workpiece just can eject chuck automatically, easy to operate, the effect height, cost is low.
