Portable profile surface quality detection instrument

Abstract

The invention discloses a portable profile surface quality detection instrument which comprises a rack, roller wheels, clamping wheels and sensors, wherein the rack is in a U-shaped structure comprising side walls; the roller wheels are installed at the bottom of the rack; the clamping wheels and the sensors are respectively arranged on the two side walls of the rack in pair; and an aluminum profile inserting space is formed between the clamping wheels. A rack width adjusting device and a rack height adjusting device are arranged on the rack. The sensors are inductive displacement sensors or non-contact type image sensors. The instrument further comprises a detection signal processing system which comprises a microcomputer and a transmitter, wherein the transmitter is respectively and electrically connected with the sensors and the microcomputer. The instrument has the beneficial effects of being simple in structure, convenient in hand-lifting operation, particularly applicable to on-site checking of large-sized aluminum profiles, and high in efficiency when being compared with manual detection, with accuracy, rapidness and convenience.

Description

technical field [0001] The invention relates to the technical field of profile surface quality detection, in particular to a portable profile surface quality detector. Background technique [0002] Profiles, especially aluminum profiles, are widely used in civil and industrial applications as light materials, such as large plates used in "moving cars", aluminum ship materials, etc. In the large-scale profile production line, aluminum ingots are sawn and cut after heating, extrusion, quenching, stretching and straightening, comprehensive inspection, artificial aging and other processes, and then inspected and put into storage. With the development of technology, there are higher requirements for the surface quality of aluminum profiles, such as surface indentation, surface cracks, surface flatness, etc. At present, most cases are online manual inspection or visual inspection, and distinguish qualified and unqualified products according to standards. Manual inspection is not...

AI Technical Summary

Problems solved by technology

Manual inspection is not only labor-intensive, but also affected by on-site light, human fatigue, and differences in inspection personnel will cause inconsistent implementation of inspection standards, resulting in misjudgment, and ultimately lead to a reduction in quality control capabilities

For large profiles, if it is detected on a large measuring device, it will be difficult to lift, site, etc., and it is not feasible
