The thimble device with the head can be automatically swung

Abstract

The invention discloses a thimble device with a head that can automatically swing, which includes a centering handle and a head sliding part. The centering handle includes a handle and a head formed on the top of the handle. A coupling part is provided at the top of the top handle. The head slider is slidably arranged on the head of the top core handle. The slider is fixed to the fixing part of the head and a thimble head combined with the sliding assembly, and the sliding assembly revolves around the joint part; the present invention can be combined with the thimble by the head slider The distance formed between the joints of the mandrel automatically slides and deflects in a circular manner, and then balances and compensates the center deflection tolerance generated when the workpiece is clamped, allowing the thimble to be completely aligned with the center of the workpiece without It will cause deflection of the thimble and achieve the effect of increasing the service life of the thimble bearing and the tailstock of the lathe.

Description

technical field [0001] The invention relates to a thimble device processed by a lathe, in particular to a thimble device whose head can be automatically swung. Background technique [0002] The existing lathe clamps the workpiece on the chuck of the main shaft, and the thimble on the tailstock of the lathe is pressed against the center hole at the end of the workpiece. When the spindle of the lathe drives the workpiece to rotate and turn, the thimble can withstand The end of the workpiece rotates synchronously with the workpiece, so that the workpiece can rotate stably, and then the rotating workpiece is cut by the tool. [0003] General thimbles can be divided into fixed thimbles and movable thimbles, and movable thimbles can be divided into fixed movable thimbles and replacement movable thimbles, of which: [0004] Such as Figure 12 Shown is an existing fixed thimble 60, the fixed thimble 60 includes a centering handle 61, the centering handle 61 is a handle body extendi...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the problem that the existing thimble cannot be aligned with the center due to the tolerance of the center deflection of the workpiece itself when in use, resulting in unstable cutting and affecting the service life of the thimble bearing and the tailstock of the lathe, the main purpose of the present invention is to Provide a thimble device whose head can swing automatically, which is equipped with a head slider that can slide along with the yaw of the workpiece, which can be used to compensate the center deflection tolerance generated when the workpiece is clamped, so that the thimble Align the center of the workpiece completely, thereby improving the aforementioned problems
