Problems solved by technology

But this device is only suitable for the case where the supporting arm of the laser sensor is short. When measuring the long-distance of the tubular member, the length of the supporting arm of the laser sensor needs to be increased, and the distance between the two laser sensors will change during the movement, which will affect the detection results.

Abstract

The invention discloses a two-dimensional automatic laser thickness-measurement device, system and method of a tubular component. The thickness-measurement device comprises a base seat, a horizontal moving sliding rail, a horizontal moving sliding table, a long-distance supporting upper-cantilever, a long-distance supporting lower-cantilever, a first laser displacement sensor, a second laser displacement sensor and a rotating chuck supporting structure. The thickness-measurement system includes a moving control module, a data collection module, a data reconstruction module, a display module, awork procedure module and the above device. The thickness-measurement method comprises the steps of: fixing a to-be-detected object; starting the device to rotate the to-be-detected object, and simultaneously moving the horizontal moving sliding table along the horizontal moving sliding rail to the other end of the device; emitting lasers by the laser displacement sensors in opposite directions to complete thickness measurement of an entire tubular structure; and displaying a measurement result and an analysis result by the display module. The device, the system and the method effectively avoid changes which are of distance between the laser sensors and are caused due to an excessive stroke, thus effectively reduce thickness measurement errors, and improve thickness measurement accuracy.

Description

technical field [0001] The invention relates to laser displacement measurement and automatic control technology, in particular to a two-dimensional automatic laser thickness measurement device, system and method for tubular components. Background technique [0002] Mattyne (Suzhou) Auto Parts Co., Ltd. has disclosed a utility model patent for "an online laser thickness measuring device", country: China, publication number: CN201720861968.2, publication date January 30, 2018, and has been authorized . In the utility model, two laser sensors are fixed, and the member to be measured is moved to realize thickness measurement at different positions. Due to the large volume and heavy weight of large tubular structures, it is difficult to achieve uniform horizontal movement. Therefore, this scheme cannot be applied to the thickness measurement of long tubular components. [0003] Shanghai Kaiduo Electromechanical Equipment Co., Ltd. has disclosed a utility model patent for "a las...
