DETAILED DESCRIPTION

[0015] The following is a more detailed description of the detection device for casting defects of the present invention in conjunction with the accompanying drawings and through specific implementation methods.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0017] See also Figure 1-2 The present embodiment is a device for detecting defects in castings. The device uses a detection mechanism to adjust the height of the casting and realizes autonomous rotation of the casting. It cooperates with a detection probe to scan and detect the casting. It can realize the detection of castings of various sizes and effectively improve the detection efficiency. The device mainly includes a conveying mechanism and a detection mechanism, and the conveying mechanism and the detection mechanism are both installed on a frame 1.

[0018] In this embodiment, see Figure 1-2 The conveying mechanism includes a conveyor belt 4 and a casting tray 16. The casting tray 16 is placed on the conveyor belt 4 through the positioning plate 13. The conveyor belt 4 is installed on the frame 1 through the transmission wheel 3. The conveyor belt 4 is evenly provided with placement holes 21. The center of the placement hole 21 is a through hole. The edge is concave and matches the side groove at the bottom of the positioning plate 13, which is convenient for the rapid positioning and placement of the positioning plate 13. The center limiting groove 17 at the bottom of the casting tray 16 matches the surface shape of the positioning plate 13. The edge of the casting tray 16 contacts the conveyor belt 4 to ensure the smoothness of the conveying process.

[0019] In this embodiment, see Figure 1-2 A lifting assembly and a rotating assembly adapted to the positioning disk 13 are installed in the middle of the frame 1. The lifting assembly includes an electric telescopic rod 10 and a top head 12. The top head 12 is installed at the free end of the electric telescopic rod 10. The size of the top head 12 matches the positioning groove 14 at the bottom of the positioning disk 13, so that the top head 12 can extend into the positioning groove 14 and steadily lift the positioning disk 13. The rotating assembly includes a rotating motor 6, a connecting rod 7 and a sleeve 9. The rotating motor 6 is installed on the bottom plate. The two ends of the connecting rod 7 are respectively connected to the output shaft of the rotating motor 6 and the bottom of the electric telescopic rod 10. The middle part of the connecting rod 7 is rotatably connected to the base 5 through the lower bearing 8, and the sleeve 9 is fixedly connected to the base 5. The fixed end of the electric telescopic rod is rotatably connected to the inner side of the sleeve 9 through the upper bearing 11.

[0020] In this embodiment, see Figure 1 A gantry 18 is installed on the bottom plate 2 in the middle of the frame 1. T-shaped grooves are opened axially on the top and sides of the gantry 18. Top detection probes 20 and side detection probes 19 are respectively installed in the T-shaped grooves through sliders. Fasteners (not shown in the figure) are provided on the sliders to fix the detection probes when adjusting their positions.

[0021] When in use, the positioning plate and the casting tray are placed in the placement holes of the conveyor belt in turn. When the casting tray with the casting moves to the bottom of the gantry, the conveyor belt stops moving, and the free end of the electric telescopic rod moves upward to the top and extends into the positioning groove at the bottom center of the positioning plate, and continues to move upward until the casting rises to the specified detection height. The two detection probes scan the detection surface at the top and side of the casting respectively. At this time, the rotating motor starts, driving the casting to rotate one circle, and cooperates with the two detection probes to complete the full-body scanning and detection of the casting. The free end of the electric telescopic rod drops to detach from the positioning plate, and the conveyor belt moves forward to perform defect detection on the next casting. The operation steps are simple, the detection efficiency is high, and it is comprehensive and without omissions.
