Laser adjustable multipurpose measuring device and measuring method thereof

Abstract

The invention discloses a laser adjustable multipurpose measuring device and a measuring method thereof. The measuring device comprises an adjustable laser transmitter mounted on a machine tool, transition sleeves arranged in two ends of a measured hole, a forward laser receiver and a reverse laser receiver which are respectively arranged in the transition sleeves. The method comprises the following steps: firstly, levelling the base plane of the measured hole and the machine tool; fixing the adjustable laser transmitter on a main shaft of the machine tool; regulating the laser beam of the laser and the stretching direction of the main shaft of the machine tool on the same straight line; moving the main shaft of the machine tool to the approximate central position of the measured hole; inserting the forward laser receiver and the reverse laser receiver into the transition sleeves; and then inserting the transition sleeves to two sides of the measured hole, and respectively reading thenumerical value of the forward laser receiver and the reverse laser receiver, thus the verticality or concentricity of the measured hole relatively to the base plane is obtained. According to the invention, the verticality of a deep hole and the base plane and the concentricity of the stretching direction of the main shaft of the machine tool and the hole axis line can be convenient and efficientto measure on line and the product quality can be ensured.

Description

technical field [0001] The invention relates to a laser adjustable multi-purpose measuring device and a measuring method thereof. Background technique [0002] The diameter of the tube sheet of the nuclear power evaporator is φ3000mm and the thickness is 600mm. There are nearly 10,000 deep holes on it. It is necessary to measure the verticality of each deep hole relative to the reference plane based on the primary side plane of the nuclear power evaporator tube sheet. The deviation of the verticality of the deep hole will directly affect the installation of the support plate and whether it can smoothly and accurately pass through the U-shaped tube bundle with a length of more than ten meters in nearly ten thousand rectangular tube holes. [0003] The blowdown pipe on the secondary side of the nuclear power evaporator tube plate adopts the process of pre-processing the inclined hole on the barrel, and then welding the extension section of the blowdown pipe on the outside of t...

AI Technical Summary

Problems solved by technology

If the measured hole size is small or the hole is very deep, it is very difficult to make the mandrel, and the cost is too high

In addition, three-coordinate measuring machines can also be used for measurement, but three-coordinate measurement is limited by the size of the product, and it is not suitable for the detection of large-size products
