Abstract

The invention discloses a device and a method for calibrating center jitter. The device comprises a magnetic meter base, a first measuring meter and a second measuring meter, as well as a measuring frame, a T-shaped screw rod, a nut and a gasket; the measuring frame comprises a base and a straight rod which is vertically fixed on the base, a steel upper base plate with the upper surface parallel to the bottom surface of the base is fixed at the upper end of the straight rod; and a screw rod slot is arranged on the base. The calibration method comprises one time of lower center calibration andtwo times of upper center calibration. The calibration method can accurately detect that the central line of an upper center at the time is not coincided with the rotation center, thereby carrying out the corresponding adjustment of the position of a work piece and further avoiding the precision bias during the processing of a gear shaft.

Description

Method of Correcting Top Runout technical field The invention relates to a device for correcting top runout and a method for correcting the top runout, in particular to a device for correcting the radial runout of the upper top of a gear grinding machine and a method for correcting the top runout. Background technique When the gear grinding machine processes gear shaft parts, two tops are often used to position and clamp the shaft blank in the up and down direction, and then perform gear grinding on the shaft blank. Among them, the lower center (referring to the mold with the lower center) is fixed on the rotary table, and the axis of the lower center is required to coincide with the rotation center of the table, and the upper center (referring to the mold with the upper center, the tire The tool comes with the gear grinding machine) is fixed on the upper top frame, the upper top frame can move up and down and rotate relative to the frame of the gear grinding machine, but ...
