Problems solved by technology

[0002] Pumps and motors are important rotating equipment in nuclear power plants. In the prior art, the shaft and hole roundness measurement tooling is prone to tilt when measuring the roundness of the shaft, resulting in inaccurate positioning and measurement. Jamming and straining often occur during the assembly process, causing damage to components and reducing the safety and economy of nuclear power plant unit operation

Abstract

The invention discloses a shaft and hole roundness measurement tool, and relates to the technical field of shaft and hole roundness measurement; the shaft and hole roundness measurement tool comprisesa shaft roundness measurement tool for measuring the roundness of the circumference of a shaft, and a hole roundness measurement tool for measuring the roundness of the circumference of a hole; the shaft roundness measurement tool comprises a first arc-shaped plate and a first positioning arc-shaped plate; an inner cutting edge is formed in the inner side of the first arc-shaped plate, and the arc-shaped surface of the first positioning arc-shaped panel and the arc-shaped surface of the inner cutting edge are located on the same arc surface; the hole roundness measurement tool comprises a second arc-shaped plate and a second positioning arc-shaped plate; and an outer cutting edge is arranged on the outer side of the second arc-shaped plate, and the arc-shaped surface of the second positioning arc-shaped panel and the arc-shaped surface of the outer cutting edge are located on the same arc surface. The shaft roundness measurement tool and the hole roundness measurement tool can be effectively prevented from being obliquely placed, so that the roundness measurement precision of the circumference surface of the shaft and the hole can be further improved, and the assembling precisionof the shaft and the hole can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of shaft and hole roundness measurement, in particular to a tool for shaft and hole roundness measurement and a use method thereof. Background technique [0002] Pumps and motors are important rotating equipment in nuclear power plants.
