Abstract

The invention discloses a multifunctional drill chuck of a lathe tailstock. A taper handle and a fixing disk are welded integrally. A spring and a movable pin are installed on the taper handle. A handle is connected to the taper handle and the movable pin through a pin shaft. A downward-pressing handle can drive the movable pin to be separated from a rotary disk, and can reset automatically after being loosened. The rotary disk is connected to the fixing disk through a positioning pin and a nut, and the rotary disk can rotate freely with the positioning pin as the axis. The drill chuck is installed on the rotary disk. The multifunctional drill chuck of the lathe tailstock has the beneficial effects that machining of multiple hole diameters and threaded holes of machined parts is completed at a time, so that the machining error caused by repeated replacement of the taper handle is avoided, and the workpiece machining precision and the operation efficiency are improved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a multifunctional drill chuck for a lathe tailstock. Background technique [0002] Usually, to process round holes or threaded holes with different diameters on a lathe, it is necessary to install taper shanks and drill chucks on the tailstock of the lathe multiple times. Due to the multiple installations, the accuracy of parts with concentricity requirements will be greatly affected. impact, and it is time-consuming and labor-intensive, and the production efficiency is low. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art, and provides a multifunctional drill chuck for the tailstock of a lathe to solve the problem of completing the processing of multi-diameter and threaded holes at one time. The technical solution adopted in the present invention is: taper shank and The fixed plate is integrally welded, and the spring...
