Manufacturing method for zigzag shafting alignment tool

Abstract

The invention discloses a manufacturing method for a zigzag shafting alignment tool, and relates to the field of alignment of zigzag shafting. The manufacturing method includes respectively manufacturing a pair of alignment pointers between an input shaft and an output shaft, wherein the input shaft and the output shaft are adjacent and an included angle is formed between the both, and each alignment pointer is a mechanical member formed by welding of a flange and a straight steel bar with a tapered tip; manufacturing a set of alignment right-angle ruler comprising a first right-angle ruler arm, an angle indicating bolt and a second right-angle ruler arm, wherein a screw hole is formed at the ruler arm end of each of the first right-angle ruler arm and the second right-angle ruler arm, the angle indicating bolt penetrates the screw hole to fix the first right-angle ruler arm and the second right-angle ruler arm together, and the first right-angle ruler arm and the second right-angle ruler arm rotate around the angle indicating bolt which displays included angle between the first right-angle ruler arm and the second right-angle ruler arm. By the method, both angle and offset can be measured, measuring results are visual, measuring accuracy is high, construction is simple and convenient, the tool is convenient to demount, and production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of zigzag shaft alignment, in particular to a manufacturing method of zigzag shaft alignment tooling. Background technique [0002] In mechanical engineering and marine engineering power transmission shafting, digital display angle rulers and universal angle rulers are often used. The measurement principle of this type of angle ruler is to use one side of the angle ruler as a reference, and temporarily set it at a certain angle. Fix on one of the two measuring objects that need to measure the angle, use the sensor installed on the other side of the angle ruler or the rotating mechanism to measure the position and displacement of the other measuring object, and obtain the angle between the two size. Although this type of angle ruler can accurately measure the angle between two object planes, due to the limitation of the measurement principle, it is impossible to measure the offset and twist of the measured object. So...

Although this type of angle ruler can accurately measure the size of the angle between two object planes, due to the limitation of the measurement principle, it is impossible to measure the offset and twist of the measured object

Some specific tasks, such as: the alignment of the zigzag shaft system, etc., need to measure the plane angle, offset and twist between two objects at the same time, the general angle ruler can only roughly measure the angle, offset The quantity can only be estimated in advance. During calibration, the measured values ​​of the knuckle angle and offset of the input and output shafts are inaccurate, and the values ​​cannot be monitored and adjusted. After calibration with such a process method, shafting vibration and bearing heating often occur , abnormal noise and other unforeseen failures

At present, there is no tool that can accurately measure both the knuckle angle of the shaft and the offset of the shaft
