Center device with head capable of automatically deflecting

Abstract

The invention discloses a center device with the head capable of automatically deflecting. The center device comprises a center handle and a head sliding part. The center handle comprises a handle portion and the head which is formed at the top end of the handle portion; a combining portion is disposed on the head; the head sliding part is slidably disposed on the head of the center handle; the head sliding part comprises a sliding member, a clamping member clamped at the top of the sliding member, a fixed member which penetrates through the sliding member and is fixed to the head and a center head which is combined with the sliding assembly; the sliding assembly acts around with the combining portion as the center. The center device can automatically slide and deflect in a circumference rounding mode by the aid of the space formed by combining the head sliding part with the combining portion of the center handle, therefore the center deflection tolerance caused during clamping of a machined object is compensated in balance, a center can be totally aligned to the center of the machined object without center deflection, and the effect of prolonging service life of a center bearing and a lathe tailstock is achieved.

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
