[0004] Therefore, we propose a countersinking tool for horseshoes with curved holes, which can solve the above problems. Utility Model Content

[0019] Please see Figures 1-4This utility model provides a technical solution: a tooling for countersinking curved holes in horseshoes, including a processing table 1, a cylindrical positioning block 11 rotatably connected to the upper side of one side of the processing table 1; a positioning mechanism for positioning the curved holes in the horseshoes, the positioning mechanism including a servo motor 15 and a Hall sensor 18, an arc-shaped positioning groove 12 is opened in the middle of the upper surface of the positioning block 11, a drive rod 16 is horizontally welded to the middle of the side of the positioning block 11 near the processing table 1, an installation groove 14 is opened inside the upper end of the processing table 1, one end of the drive rod 16 placed inside the installation groove 14 is fixedly connected to the shaft end of the servo motor 15, the servo motor 15 is fixedly connected to the inner wall of one side of the installation groove 14, and the drive rod 16 is rotatably connected to the inner wall of the other side of the installation groove 14 through a bearing.
[0020] In this technical solution, the lower end of the shoe can be positioned by the positioning groove 12 on the surface of the positioning block 11 (it should be noted that the positioning groove 12 matches the model and size of the shoe). The servo motor 15 is controlled by the controller 13 to work, and the positioning block 11 can be rotated by the drive rod 16, thereby rotating the shoe. This makes it convenient to adjust the position of the curved hole of the shoe for countersinking.
[0021] In this embodiment, a magnet 17 is fixedly connected to one side of the drive rod 16 inside the mounting groove 14. The magnets 17 are evenly distributed on the outside of the drive rod 16. A Hall sensor 18 is fixedly connected to the inner wall of the top of the mounting groove 14. The Hall sensor 18 corresponds to the magnet 17. A controller 13 is provided on the side of the processing table 1 away from the positioning block 11.
[0022] In this technical solution, as the drive rod 16 drives the positioning block 11 to rotate, it can drive the magnet 17 to rotate. When the magnet 17 rotates to the point where its upper end is aligned with the Hall sensor 18, the Hall sensor 18 can transmit data to the controller 13, thereby detecting and controlling the rotation angle of the drive rod 16. Furthermore, the controller 13 can automatically control the rotation angle of the positioning block 11, thereby automatically adjusting the position of the horseshoe arc hole.
[0023] In this embodiment, the fixing mechanism is used to fix the horseshoe. The fixing mechanism includes a lead screw 23. A limit groove 2 is opened at the upper end of the positioning groove 12 on the side away from the servo motor 15. A limit protrusion 21 is slidably connected to the inner side of the limit groove 2. A connecting groove 22 is opened horizontally at one end of the limit protrusion 21 located inside the limit groove 2. The lead screw 23 is threadedly connected to the connecting groove 22. The lead screw 23 is rotatably connected to the inner wall of the limit groove 2 through a bearing. A handwheel 24 is fixedly installed at one end of the lead screw 23 located outside the positioning block 11. The protruding end of the limit protrusion 21 is movably connected to the positioning groove 12. The size of the limit protrusion 21 matches that of the limit groove 2.
[0024] In this technical solution, when the operator turns the handwheel 24, the lead screw 23 can be rotated. The lead screw 23 is threadedly connected to the connecting groove 22 inside the limiting protrusion 21. During the rotation of the lead screw 23, the protruding end of the limiting protrusion 21 can be pushed to move into the positioning groove 12, further pressing against the outer side of the lower end of the shoe, thereby fixing the shoe and improving the stability of the shoe during rotation.
[0025] When using a countersinking fixture for a horseshoe with an arc-shaped hole, the lower end of the horseshoe is inserted into the arc-shaped positioning groove 12 on the surface of the positioning block 11 to position the horseshoe. At this time, the arc surface of the horseshoe is positioned on the outside of the positioning block 11. The operator turns the handwheel 24, which drives the lead screw 23 to rotate. The lead screw 23 is threadedly connected to the connecting groove 22 inside the limiting protrusion 21. During the rotation of the lead screw 23, it can push the protruding end of the limiting protrusion 21 to move into the positioning groove 12, further pressing against the outside of the lower end of the horseshoe, thereby fixing the horseshoe. The servo motor 15 is controlled by the controller 13. The drive rod 16 can drive the positioning block 11 to rotate, thereby driving the shoe to rotate, which facilitates the adjustment of the position of the shoe's arc hole for counterboring. During the rotation of the positioning block 11 driven by the drive rod 16, the magnet 17 can also rotate. When the magnet 17 rotates to the point where its upper end is aligned with the Hall sensor 18, the Hall sensor 18 can transmit data to the controller 13, thereby detecting the rotation angle of the drive rod 16 and the positioning block 11. When the shoe outside the positioning block 11 rotates to the designated position, the controller 13 can automatically control the servo motor 15 to stop working, thereby automatically adjusting the position of the shoe's arc hole.
