DETAILED DESCRIPTION

[0016] The following is a more detailed description of the position detection device for casting processing positioning of the present invention in conjunction with the accompanying drawings and through specific implementation methods.

[0017] 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.

[0018] See also Figure 1-2 The present embodiment is a position detection device for positioning castings. The detection device uses a laser lamp to replace the detection column, which greatly improves the detection efficiency. The positioning mechanism uses two adjustable positioning wheels to replace the positioning column, which greatly improves its scope of application. It mainly includes a positioning mechanism and a detection mechanism, and the detection mechanism is arranged above the positioning mechanism.

[0019] In this embodiment, see Figure 1 The detection mechanism includes a column 2, a rotating seat 3 and a laser lamp 8. The laser lamp 8 is connected to the rotating seat 3 through a connecting rod 4. A limited block is fixed at the left end of the connecting rod 4. The laser lamp 8 is slidably connected to the connecting rod 4 through a sliding seat 7. A scale is provided on the connecting rod 4 for measuring the distance between the laser lamp and the rotating seat. The rotating seat 3 is installed on the base 1 through the column 2. The right end of the connecting rod 4 is rotatably connected to the rotating seat 3. A dial 6 is provided on the rotating seat 3. A pointer 5 is fixed at the midline position of the upper surface of the connecting rod 4 for measuring the rotation angle of the connecting rod. The column 2 is fixed to the edge position of the right side of the base 1. The left side of the base 1 is a semicircular plate. A positioning hole 10 is opened in the center of the semicircular plate. The laser lamp is basically above the positioning hole, which can reduce the moving distance of the laser lamp during measurement, facilitate measurement, and improve efficiency. Ball bearings are evenly arranged on the base 1 around the positioning hole 10 to facilitate moving the casting so that the center hole of the casting coincides with the center of the positioning hole to ensure the accuracy of measurement.

[0020] In this embodiment, see Figure 1-2The positioning mechanism includes a positioning wheel 11, a rotating unit and a driving unit. The positioning wheel 11 is installed on the upper part of the positioning rod 12. The lower part of the positioning rod 12 moves toward each other through the driving unit. The driving unit includes a double-headed screw 14, a bottom plate 13 and a sleeve 19. The lower part of the positioning rod 12 is threadedly connected with the double-headed screw 14. The threads at both ends of the double-headed screw 14 are in opposite directions and have the same pitch. The lower part of the positioning rod 12 contacts the bottom plate 13. The sleeve 19 is sleeved on the straight parts at both ends of the double-headed screw 14. The middle part of the sleeve 19 is fixedly connected to the bottom plate 13 through a fixing block 18. The positioning rod 12 is rotated by the unit to the positioning hole 1 on the base 1. 0 is axially rotated around the center, the rotating unit includes a rotating ring 16 and a rotating wheel 15, the rotating ring 16 is fixed below the base 1, the center of the rotating ring 16 coincides with the center of the positioning hole 10, a fan-shaped through groove 17 is provided on the side of the rotating ring 16, a limiting ring track (not shown in the figure) is arranged in the fan-shaped through groove 17, the rotating wheel 15 is installed on the outside of the sleeve 19, and sliders are installed on the sleeves on both sides of the rotating wheel to limit the axial movement of the rotating wheel along the sleeve and prevent the sleeve from rotating. The outer edge of the rotating wheel matches the shape of the limiting ring track, and the limiting ring track serves as a limiting position for the rotating wheel, so that the two rotating wheels can move clockwise or counterclockwise along the limiting ring track.

[0021] When in use, first place the casting on the base and move it until the center hole and the positioning hole basically coincide with each other. At this time, the two positioning wheels are in the center hole of the casting. Turn the handwheel to make the two positioning wheels move synchronously in opposite directions until one positioning wheel contacts the inner wall of the center hole. Continue to turn the handwheel until both positioning wheels contact the inner wall of the positioning hole. Without turning the handwheel, turn the sleeve and rotate it 90° along the limit ring track to complete the adjustment and positioning of the casting. During this period, when the casting moves under the action of the positioning wheel, the action of the ball under the casting greatly reduces the force required to move the casting, thereby reducing the difficulty of positioning the casting.
