Lathe tail fixing device integrated with clamping and drilling of center hole

Abstract

The invention discloses a lathe tail fixing device integrated with clamping and drilling of a center hole. The lathe tail fixing device comprises a center shaft, an elastic chuck, bearings, an inner flange, an outer flange, connecting rods, fixing screws, linear bearings, springs and spring washers; the center shaft is provided with a taper hole which is provided with the elastic chuck; the bearings are installed on the center shaft; the inner flange is installed on outer rings of the bearings; the outer flange is arranged on a boss of the inner flange; the springs are arranged on the outer flange; the spring washers are installed on a boss of the inner flange; the connecting rods are fixed to the outer flange; the linear bearings are installed in through holes of the inner flange, and arein contact with the connecting rods and the inner flange; and the fixing screws are arranged in screw holes of the connecting rods. The lathe tail fixing device not only has the clamping function applicable for common workpieces, but also can be used for clamping and drilling of the center hole for eccentric parts, and additional installation of a center frame is not required; and the required auxiliary time for location and correction of the workpieces is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a lathe accessory, in particular to a lathe tail fixing device with the functions of a clamp and a center hole. Background technique [0002] The lathe is a kind of machining equipment with strong versatility and a wide range of processing. The lathe can complete most of the parts processing with some accessories. However, when encountering eccentric parts, the lathe processing is limited. [0003] At present, there is only one kind of four-jaw single-action rotary chuck for the tailstock of a lathe on the market. This chuck is used for clamping the tailstock of a lathe and needs to be customized. The structure of the device is not very reasonable, and its application is limited. [0004] 1) The standard four-jaw chuck is used to clamp the workpiece, the application diameter range is too small, and the self-weight is too large. [0005] 2) The workpiece can only be clamped and corrected, but the center process hole cannot be ...

AI Technical Summary

Problems solved by technology

[0004] 1) The standard four-jaw chuck is used to clamp the workpiece, the application diameter range is too small, and the self-weight is too large

[0005] 2) Only the workpiece can be clamped and corrected, but the center process hole cannot be punched

This leads to the need to use the center frame to punch the center process hole during processing, and the work efficiency is low
