Circle center positioning tool and usage method thereof

Abstract

The invention provides a circle center positioning tool and a usage method thereof and belongs to the technical field of machinery. The circle center positioning tool comprises a positioning sliding block I, a positioning structure, a positioning sliding block II, a sliding rail, a measuring sliding block, a roller I, a roller II, a pressing plate, a positioning knob and a drill bushing. The sliding rail is of a U-shaped structure, scales are marked on one side, zero scales are marked at the position close to the closed end, and readings on the two sides of the zero scales are sequentially increased. The pressing plate is provided with two grooves through which the sliding rails pass. The positioning sliding block I can slide on the sliding rail through a pressing plate structure, and rollers I are arranged at the two ends of the positioning sliding block. The positioning slide block I is fixed at the zero graduation of the slide rail and provided with rollers I at two ends; and the positioning slide block II is arranged between the positioning slide block I and the positioning structure. The measuring sliding block is located between the positioning structure and the closed end ofthe sliding rail. The device is simple in structure and convenient to machine, when the circle center of the through hole is determined, only one worker is needed for operation regardless of the radius of the through hole, human uncontrollable factors are reduced, and the working efficiency is improved.

[0002] With the development of production technology, the role of templates in aircraft manufacturing is becoming more and more prominent. It is very common to design through holes on templates or parts through holes. In many cases, we need to determine the center of the through hole to design concentric circles or Other process designs are based on the central hole, but it is very difficult to obtain the center of the space through hole, especially the space through hole with a large radius

The traditional method of obtaining the center of the circle is to measure the radius of the through hole, and use a steel ruler to place it at the diameter of the through hole. The measured value is equal to twice the radius, and it is vaguely regarded as the diameter of the through hole. This method is less accurate, and the through hole It is difficult to obtain the radius, assuming that the center of the circle is found, it is not convenient to perform process operations, or the center of the circle is easily deviated during process operations

This in turn affects the production efficiency of prototypes or parts

Moreover, during the operation process, there are many uncontrollable factors, the success rate is low, and the accuracy is low.

[0003] It cannot meet the design requirements, and in serious cases, it will lead to the scrapping of the whole part and affect the quality of aircraft products
