Problems solved by technology

This method not only requires one-to-one custom profiling tooling for blank parts, but also the detection process is time-consuming and labor-intensive, and the efficiency is low. The biggest problem is that the measurement accuracy is very poor, and there are manual and subjective judgments in the detection process. The resulting positioning and measurement deviation of the blank not only affects the yield of the blank, but also increases the difficulty of assembly, reduces the fatigue life of the blank, and causes a series of quality problems

Embodiment Construction

[0023] Such as Figure 1~ The laser measurement system shown in 4 is applicable to the blank 8 with no feature space curved surface, which includes the guide rail 1 for transmission, especially the linear guide rail 1 is the preferred solution, which is different in that: in order to measure the titanium alloy that needs to be measured The blank 8 is effectively positioned, and a flexible support 2 is installed on the guide rail 1 . At the same time, in consideration of automatic high-precision measurement, a robot device 3 is arranged on the periphery of the flexible support 2, and a laser sensor 4 is installed on the detection end of the robot device 3. In order to facilitate control, an industrial computer 5 is connected to the communication port between the robot device 3 and the laser sensor 4, so that the robot device 3 collects data on the blank 8 within the range of movement of the robot device. Moreover, the flexible support 2 and the laser sensor 4 are controlled by...

Abstract

The present invention relates to a laser measurement system suitable for non-feature space curve blank piece and a processing location method thereof. A robot is equipped with a three-dimensional laser to perform comprehensive scanning of formed blank piece and obtain dot cloud data of the blank piece, and then collected dot point data and the CAD numerical simulation are subjected to optimized matching through the rapid and effective graphic image algorithm so as to directly compare a tough piece theory numerical simulation with the dot cloud data, comprehensively analyze the size precision condition after the tough piece is formed and analyze the quality problem reason. The laser measurement system suitable for a non-feature space curve blank piece and the processing location method thereof can perform adsorption location of different blanks by using a flexible support, and the laser measurement system can be configured to perform measurement and location work of different blank pieces. The digitalization and the automation of the measurement and location matching process are realized, and the laser measurement system has high flexible characteristic to apply to the measurement and the location of different blank pieces; and moreover, the deviation caused by manual measurement can be effectively eliminated, and the cost is reduced.

Description

technical field [0001] The invention relates to a laser measuring system and a detection method for blanks, in particular to a laser measuring system and a processing and positioning method suitable for blanks with no-featured spatial curved surfaces, which can be preferably implemented on titanium alloy blanks. Background technique [0002] Due to the excellent comprehensive properties of titanium alloys, it has been widely used in the aerospace industry. Due to its poor forming ability and other problems, the titanium plate material generally adopts a hot stamping forming process. Considering the problem of the deformation of the titanium plate after forming, it is not possible to use features such as holes or grooves for positioning during the hot forming process. It is a free state forming without blank holder force, that is, during the forming process, the blank is completely Free stretching state. The problem caused by this is that the specific position in the blank ...
