Abstract

The invention discloses a straightness detection device for a hexahedral shaft and a data processing method. Three sets of measuring devices of the same structure are mounted on a curved mounting plate with 60-degree angles formed between every two sets of measuring devices; three axial lines intersect at the ideal center of the hexahedral shaft; roller bearings are closely attached to three surfaces of the hexahedral shaft; the mounting plate slides on a guide rail through a slider, so that the measuring devices move from one end of the guide rail to the other end of the guide rail so as to measure relative error data; the hexahedral shaft is rotated by 180 degrees, so that relative error data are measured; the relative error data of every two opposite surfaces are subtracted from each other sequentially, obtained relative error data are divided by 2, and therefore, the deviation quantities of the axis of the hexahedral shaft in three directions are obtained; and the deviation quantities are displayed on a three-coordinate system having intervals of 120 degrees; and the obtained three-axis coordinate intuitive data are subjected to coordinate transformation so as to be transformedinto rectangular coordinate system coordinates, and therefore, the position coordinate of the deviated axis of the hexahedral shaft can be obtained. According to the straightness detection device forthe hexahedral shaft and the data processing method of the invention, sensors can be protected; the service life of the straightness detection device is prolonged; detection is fast; and the intuitive sectional deviation data can be obtained directly.

Description

technical field [0001] The invention relates to a straightness detection device, in particular to a hexagonal axis straightness detection device and a data processing method. technical background [0002] The hexagonal shaft of the water pump is the rotating shaft applied to the water pump, and the straightness requirement is high. However, the straightness of the produced shaft cannot meet the requirements and must be straightened in the later stage. The early traditional straightening method is manual straightening through experience, and the straightening quality is all based on experience, and the quality cannot be guaranteed. Then there was a series of straightening machines. [0003] Straightening machine is a kind of equipment for straightening metal profiles, bars, pipes, wires, etc. The straightening machine squeezes the rods etc. through the electric cylinder to change the straightness. Before straightening, the first thing to do is to check the straightness of...
