Technical Field
[0001] The invention belongs to the technical field of industrial spare parts defect detection, and in particular relates to an industrial spare parts defect detection device. Background Art
[0002] In modern industry, spare parts are essential for the installation and connection of basic firmware. The quality of spare parts determines its service life and application intensity. The defect detection of spare parts is carried out through the combination of cameras, sensors and image processing algorithms. When the intensity of light irradiation changes, it will affect and deviate its shape, size and surface quality. When cameras and image processing algorithms detect defects in spare parts, there are environmental changes that affect the detection results, specifically involving changes in light illumination and the impact of dust and vibration on the stability and accuracy of defect detection results. Moreover, defects may be very small or difficult to detect accurately, so more precise detection methods or detection systems are required. Summary of the invention

[0020] The present invention is further described below in conjunction with the accompanying drawings.
[0021] like Figure 1 As shown, a defect detection device for industrial parts includes a 60cm 2020 aluminum profile (1), which is characterized by excellent mechanical properties and corrosion resistance. It has good ductility and toughness. It has low density and light weight. Several 12 pieces (1) form a hexagonal structure through two interlocking 120° connectors (2); the outer ends of the hexagonal structures on the upper and lower sides are connected to a 1m 2020 aluminum profile (3) through right-angle connecting angle aluminum (4), and the inner ends are connected to a linear heavy-duty precision electric guide rail lead screw slide module (5) through a slide rail cross connector (6). The slider in the linear heavy-duty precision electric guide rail lead screw slide module (5) is connected to the radar through the right-angle connector (7) to drive the radar to move up and down 500mm.
[0022] Each angle of the hexagonal structure is 120 degrees.
[0023] The 1m 2020 aluminum profile (3) is arranged at intervals with the linear heavy-duty precision electric guide rail lead screw slide module (5).
[0024] The laser radar is installed on the right-angle connector of the square slider on the linear heavy-duty precision electric guide rail lead screw slide module.
[0025] The maximum stroke of the linear heavy-duty precision electric guide rail screw slide module can reach 1000mm. It is open, the force-bearing parts are mainly reflected in the middle and lower parts and the two sides, and the transmission part is exposed. It is equipped with a single guide rail and a single slider. The structure is compact and versatile. It is suitable for medium and low speed requirements and can be used in single-axis or multi-axis combinations. The motor is connected to the bearing through a high-precision plum coupling, and the effective length is 500mm stroke. The control module transmission mode is assisted by a ball screw and a linear guide.
[0026] The laser radars described above use three laser radars, which form a scanning area of 120° in pairs.

The three laser radars are always kept on the same horizontal plane through the control of the motor of the linear heavy-duty precision electric guide rail ball screw slide module by STM32ET6, with an effective stroke of 500mm. At the same time, the 120° area data scanned by each radar is processed and mapped through the host computer. Finally, the data of the three laser radars are summarized to complete the defect detection of industrial parts.
