A non-contact laser on-line detection bar straightness mechanism and detection method

Abstract

The invention discloses a non-contact laser on-line detection bar straightness mechanism and detection method, including a laser range finder, an industrial computer, a programmable logic controller and a clamping mechanism; the laser range finder is installed on the bar pressure correction On the straight machine, it is used to collect the distance data from the surface of the bar in real time, and when collecting data, there is a gap between the laser range finder and the bar; the industrial computer is connected to the laser range finder to receive and process the laser The data acquired by the rangefinder draws the straightness curve of the bar, and converts the analysis results into action instructions and feeds them back to the programmable logic controller; the programmable logic controller is connected to the industrial computer to receive the incoming signal from the industrial computer and Output action instructions to the bar pressure straightening machine; the clamping mechanism is connected with the industrial computer, and is used to clamp the two ends of the bar so that the bar passes in front of the laser rangefinder. The invention provides a basis for bar straightening, improves straightening efficiency and product qualified rate, and can be widely used in heavy machinery industries such as metallurgy.

Description

technical field [0001] The invention belongs to the field of material shape detection, and relates to a bar straightness mechanism and detection method, in particular to a non-contact laser on-line detection bar straightness mechanism and detection method applied to a bar pressure straightening machine. Background technique [0002] In the bar manufacturing industry, due to the possible bending deformation of the bar during processing and heat treatment, when the bar deforms beyond a certain level, it cannot be processed into a product and will be scrapped. Therefore, it is necessary to straighten the bar after processing and heat treatment. straight processing. The pressure straightening machine is to support the workpiece with the original bending between the two movable fulcrums of the workbench, and use the pressure head to align the most curved place for reverse bending. When the bending amount is equal to the springback amount , the curved part of the workpiece become...
