Problems solved by technology

Among them, the gap between the wheel back on the bogie and the frame is an important influencing parameter. At present, most vehicle manufacturers generally use vernier calipers to measure it, which not only requires high measurement technology for the operator, but also has high measurement accuracy. Low, prone to measurement deviation, resulting in low assembly accuracy of the bogie and prone to quality problems

Abstract

The invention discloses a hand-held laser measuring instrument, which comprises a measuring instrument main body and an attaching plate. The measuring instrument main body is provided with a laser probe, a laser emitter and a laser receiver are arranged on the laser probe, the measuring instrument main body further includes a display screen and a measuring controller, the measuring controller is provided with a timer, and the measuring controller is electrically connected with the laser probe and the display screen; and the attaching plate is provided with an attaching surface and arranged onthe measuring instrument main body, and the attaching surface is perpendicular to a laser beam emitted by the laser emitter. According to the hand-held laser measuring instrument, the attaching surface attaches to the surface to be measured, it is ensured that the emitted laser beam is perpendicular to the surface to be measured, thus obtained measuring data are more accurate, the measuring accuracy is greatly improved, during measuring, measuring personnel attaches the attaching surface to the surface to be measured to ensure the measuring accuracy, so that measuring operation is simpler, themeasuring difficulty is greatly reduced, and stability and reliability of the measuring value are ensured.

Description

technical field [0001] The invention relates to the field of measuring instruments and equipment, in particular to a hand-held laser measuring instrument. Background technique [0002] The bogie is the core component of the rail vehicle, and its manufacturing precision and assembly precision are directly related to the operation and driving safety of the vehicle. Among them, the gap between the wheel back on the bogie and the frame is an important influencing parameter. At present, most vehicle manufacturers generally use vernier calipers to measure it, which not only requires high measurement technology for the operator, but also has high measurement accuracy. Low, prone to measurement deviation, resulting in low assembly accuracy of the bogie and prone to quality problems. Contents of the invention [0003] The purpose of the present invention is to at least solve one of the technical problems in the prior art, and provide a hand-held laser measuring instrument that can...
