Method for determining position of center hole of rotary tank

Abstract

The invention provides a method for determining the position of a center hole of a rotary tank, relates to the technical field of center hole positioning methods, and aims to solve the problems of large errors and small application range when the position of the center hole of the tank is determined by a method for determining the center hole of the rotary tank in the prior art. The method comprises the following steps: calibrating an initial position of the central hole on the rotary tank as an initially-determined central hole; obtaining respective maximum circular runout values of multiplesections on the rotary tank, and obtaining a direction angle at the maximum circular runout value on each section; determining an ideal central hole position of each section; and determining the center hole position of the rotary tank according to the ideal center hole positions of the multiple sections. By adopting the method, the problems of large errors and small application range when the position of the central hole of the tank is determined by the method for determining the central hole of the rotary tank in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of center hole positioning methods, in particular to a method for determining the position of the center hole of a rotary tank body. Background technique [0002] At present, the center hole of the rotary tank body is generally: before the rotary tank body is processed on the lathe, the tank body is placed horizontally on the platform, and the radial size is divided equally according to the busbar outside the tank body. Generally, two busbars at the top and bottom in the vertical direction are selected. The farthest two busbars in the horizontal direction, according to the average size of the four busbars, determine the position of the center hole at both ends of the tank body, and then punch the center hole on the boring machine according to the line. [0003] This method determines that the position of the center hole of the tank has a large error, especially for tanks with a large diameter. The center ho...
