Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, and in particular to a precision detection device for the pre-stretching production dimensions of a high-end aluminum plate. Background Art

[0002] After rolling and heat treatment, residual stress often exists inside the aluminum plate. If it is not eliminated in time, the processed material will be deformed or even scrapped. Therefore, stretching is usually adopted to stretch the aluminum plate through a stretching machine to redistribute the internal stress and eliminate the residual stress. In this process, the aluminum plate undergoes plastic deformation, the length becomes longer, the thickness becomes thinner, and the width becomes narrower. In order to ensure that the size of the aluminum plate after stretching meets the requirements, dimensional detection is required. At the same time, by comparing the sizes before and after stretching, the error between the actual stretching rate and the preset stretching rate can be obtained. In addition, when studying the uniformity of aluminum plate stretching, it is necessary to obtain the degree of stretching at different positions on the surface of the aluminum plate.

[0003] However, traditional measurement methods cannot perform real-time measurements during the stretching process. For this reason, we propose a high-end aluminum plate pre-stretching production size precision detection device. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example 1

[0044] See also Figure 1-Figure 9 The present invention provides a technical solution: a high-end aluminum plate pre-stretching production size precision detection device, including a base 1, and also includes:

[0045] A support frame 2 is arranged on the base 1;

[0046] A hollow cylinder 3 is arranged on the support frame 2, and four rectangular columns 4 are evenly and equidistantly arranged on the hollow cylinder 3;

[0047] A plurality of marking pens 5 are correspondingly arranged at one end of the four rectangular columns 4 to mark four measuring points on the aluminum plate;

[0048] A plurality of laser distance measuring sensors 6 are also arranged at one end of the four rectangular columns 4;

[0049] The switching assembly 7 is arranged on the hollow cylinder 3, and is used to drive the marking pen 5 and the laser distance sensor 6 to deflect simultaneously, so that the laser distance sensor 6 is aligned with the measuring point;

[0050] A camera 8 is arranged at the bottom of the hollow cylinder 3 to monitor the measuring point in real time;

[0051] When used specifically: if the size of the aluminum plate is to be measured, the aluminum plate can be placed on one side of the base 1, and one end of the aluminum plate is kept facing the side wall of the base 1, and then the laser distance sensor 6 is used to sequentially illuminate the ground and the aluminum plate, so as to calculate the thickness of the aluminum plate through the program. When measuring the length and width of the aluminum plate, the laser distance sensor 6 is used to pass through the ground, the aluminum plate, and the top of the ground in sequence, so as to use the program to calculate the time between two large changes in the measurement data of the laser distance sensor 6, or the number of rotations of the drive motor 1 56 or the drive motor 2 61, to statistically calculate the length or width of the aluminum plate, and then by comparing the size data of the aluminum plate before and after stretching, the stretching degree and stretching condition of the aluminum plate can be analyzed;

[0052] When it is necessary to detect the changes in the aluminum plate during the stretching process in real time, the base 1 is first placed on the working table of the stretching machine, and the base 1 is kept parallel to the working table of the stretching machine, and then the hollow cylinder 3 and the marker 5 are driven downward to draw four symmetrical measuring points on the aluminum plate, and then the hollow cylinder 3 is raised to ensure that the camera 8 can cover multiple measuring points and record and monitor them in real time, and the marker 5 is put away by the switching component 7, and the laser distance sensor 6 is turned out and aimed at the measuring point, and then the laser distance sensor 6 is used to measure the thickness change of the aluminum plate at the pre-marked measuring point during the stretching process in real time. At the same time, the camera 8 is used to capture the image information of the measuring point before and after the stretching, and the displacement of the measuring point in the two images is calculated by the program to determine the stretching distance of the point. In this way, the stretching process of the measuring point can be monitored at a fixed point, and by comparing the displacement of the measuring point in the image before and after the stretching, we can accurately measure the stretching degree of the point;

[0054] At the same time, the adjustment component 65 is used to drive the multiple rectangular columns 4 to move, so that the distances between the four marking pens 5 and the center of the hollow cylinder 3 increase successively, and then the hollow cylinder 3 is rotated to drive the four marking pens 5 to draw four closely connected and differently colored circles on the aluminum plate, and then the camera 8 is used to photograph and monitor the circles on the aluminum plate before and after stretching, so that before and after stretching, the expansion rates of different parts of the aluminum plate may be different, which may cause the originally concentric circles to deform after stretching, and then appear to merge or misalign with each other, thereby forming other colors, so that the stretching degree and stretching unevenness of the aluminum plate can be more intuitively observed.
