Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0021] Please see Figure 1-4 A fault detection mobile device for CNC machine tools includes a base plate 1. A support plate 2 is mounted on the upper side of the base plate 1 via a lifting mechanism. A vision inspection camera 16 is mounted on the outer wall of the support plate 2 via an adjustment mechanism. The adjustment mechanism includes an electric slide rail 4 mounted on the outer wall of the support plate 2. A slide frame 5 is slidably connected to the outer wall of the electric slide rail 4. A sleeve 9 is rotatably connected to the outer wall of the slide frame 5 via a bearing. A hexagonal shaft 8 is slidably connected to the inner wall of the sleeve 9. A second electric push rod 6 is mounted on the outer wall of the slide frame 5. A first mounting plate 7 is fixedly connected to the output end of the second electric push rod 6. One end of the hexagonal shaft 8 is rotatably connected to the first mounting plate 7 via a bearing. The other end of the hexagonal shaft 8 is fixedly connected to a portal frame 13. A rotating block 14 is rotatably connected to the inner wall of the portal frame 13 via a rotating shaft. A second servo motor 17 is mounted on the outer wall of the portal frame 13, with its output end fixedly connected to the rotating block 14. A second mounting plate 15 is fixedly connected to the outer wall of the rotating block 14. The vision inspection camera 16 is mounted on the outer wall of the second mounting plate 15.
[0022] In this embodiment: the height of the visual inspection camera 16 can be adjusted by the lifting mechanism. The electric slide rail 4 is activated, causing the slide 5 to move back and forth, which in turn causes the visual inspection camera 16 to move back and forth, facilitating adjustment of its position. The second electric push rod 6 is activated, causing the first mounting plate 7 to move left and right, which in turn causes the hexagonal shaft 8 to move left and right, further causing the visual inspection camera 16 to move left and right, thus adjusting its position. The second servo motor 17 is activated, causing the rotating block 14 to rotate, thus adjusting the horizontal angle of the visual inspection camera 16. The sleeve 9 is rotated, causing the hexagonal shaft 8 to rotate, thus adjusting the pitch angle of the visual inspection camera 16. This invention allows for flexible adjustment of the position and angle of the visual inspection camera 16, reducing blind spots and effectively improving the coverage and accuracy of fault detection.
[0023] As a technical optimization of this utility model, a first servo motor 10 is installed on the outer wall of the slide 5. The output end of the first servo motor 10 passes through the slide 5 and is fixedly connected to a first synchronous pulley 11. A second synchronous pulley 12 is fixedly connected to the outer wall of the sleeve 9. The first synchronous pulley 11 and the second synchronous pulley 12 are connected by a synchronous belt drive.
[0024] In this embodiment: the first servo motor 10 is started, the first servo motor 10 drives the first synchronous pulley 11 to rotate, and then drives the second synchronous pulley 12 to rotate through the synchronous belt. The second synchronous pulley 12 further drives the sleeve 9 to rotate, thereby facilitating the adjustment of the pitch angle of the visual inspection camera 16.
[0025] As a technical optimization of this utility model, the lifting mechanism includes a first electric push rod 3 installed on the upper surface of the base plate 1, and the output end of the first electric push rod 3 is fixedly connected to the support plate 2.
[0026] In this embodiment: the first electric actuator 3 is activated, and the first electric actuator 3 drives the support plate 2 to move up and down, thereby facilitating the adjustment of the height of the visual inspection camera 16.
[0027] As a technical optimization of this utility model, two symmetrically distributed limiting rods 18 are fixedly connected to the upper end face of the base plate 1, and two limiting cylinders 19 that are slidably connected to the limiting rods 18 are fixedly connected to the lower end face of the support plate 2.
[0028] In this embodiment, the limiting rod 18 and the limiting cylinder 19 facilitate the limiting of the support plate 2, so that the support plate 2 moves up and down stably.
[0029] As a technical optimization of this utility model, the first electric push rod 3, the electric slide rail 4, the second electric push rod 6, the first servo motor 10, the vision inspection camera 16, and the second servo motor 17 are all electrically connected to an external controller.
[0030] In this embodiment, the controller facilitates the normal operation of the first electric actuator 3, the electric slide rail 4, the second electric actuator 6, the first servo motor 10, the vision inspection camera 16, and the second servo motor 17.
[0031] As a technical optimization of this utility model, the sliding connection section between the hexagonal shaft 8 and the sleeve 9 is hexagonal, and the axis of the second electric push rod 6 is parallel to the axis of the hexagonal shaft 8.
[0032] In this embodiment: by setting the sliding connection section between the hexagonal shaft 8 and the sleeve 9 to a hexagonal shape, the hexagonal shaft 8 is prevented from rotating inside the sleeve 9. The axis of the second electric actuator 6 is set parallel to the axis of the hexagonal shaft 8, which facilitates the sliding of the hexagonal shaft 8 inside the sleeve 9.
[0033] The working principle and usage process of this utility model are as follows: Activating the first electric actuator 3 causes the support plate 2 to move up and down, facilitating the adjustment of the height of the visual inspection camera 16. Activating the electric slide rail 4 causes the carriage 5 to move back and forth, which in turn causes the visual inspection camera 16 to move back and forth, facilitating the adjustment of its position. Activating the second electric actuator 6 causes the first mounting plate 7 to move left and right, which in turn causes the hexagonal shaft 8 to move left and right. The hexagonal shaft 8 further causes the visual inspection camera 16 to move left and right, thus adjusting its left and right position. The second servo motor 17 is started, which drives the rotating block 14 to rotate, thereby adjusting the horizontal angle of the visual inspection camera 16. The first servo motor 10 is started, which drives the first synchronous pulley 11 to rotate, which in turn drives the second synchronous pulley 12 to rotate via the synchronous belt. The second synchronous pulley 12 further drives the sleeve 9 to rotate, which in turn drives the hexagonal shaft 8 to rotate, thereby adjusting the pitch angle of the visual inspection camera 16. This utility model can flexibly adjust the position and angle of the visual inspection camera 16, reduce the detection blind zone, and effectively improve the coverage and accuracy of fault detection.
