[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision chamfering mold design tool, comprising an arc-shaped plate and a circular block, wherein a connecting rod is fixedly connected between the circumferential sidewall of the circular block and the inner wall of the arc-shaped plate, a rotating column is rotatably connected to the top wall of the circular block, a movable plate is sleeved on the surface of the rotating column, a chamfering and scribing mechanism is provided in the middle plate of the movable plate, an arc-shaped groove is provided on the top wall of the arc-shaped plate, a plurality of positioning holes distributed in a circumferential array are provided on the bottom wall of the groove, and a positioning mechanism is provided on the top wall of the end plate of the movable plate.

[0007] Preferably, the chamfering and marking mechanism includes a mounting groove formed on the surface of the movable plate, a crossbar fixedly connected between the two side walls of the mounting groove, a sliding block slidably connected to the surface of the crossbar, a mounting block fixed to one side wall of the sliding block, and a marking pen fixed on the plate of the mounting block.

[0008] Preferably, the chamfering and scribing mechanism further includes threaded holes evenly formed on the top wall of the movable plate, with multiple threaded holes arranged along the length of the movable plate. A fixing plate is fixed to the top wall of the sliding block, and bolts are threadedly connected to the plate body of the fixing plate, with the bolts being compatible with the threaded holes.

[0009] Preferably, the positioning mechanism includes a positioning frame fixedly installed at the top end of the movable plate, a positioning rod is provided inside the frame of the positioning frame, the top end of the positioning rod movably penetrates through the top wall of the positioning frame and is fixedly installed with a lever, and the bottom end of the positioning rod movably penetrates through the plate of the movable plate.

[0010] Preferably, the positioning rod is located directly above the positioning hole, and the rod body of the positioning rod is adapted to the cavity of the positioning hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves placing the chamfered end of the mold to be chamfered against a tapered groove. By unscrewing the bolt from the threaded hole, a sliding block can be moved along a crossbar, allowing for rapid adjustment of the chamfer radius and achieving chamfering within multiple radius ranges. Once the chamfer radius is set, the bolt can be tightened again to engage the threaded connection in the threaded hole, fixing the position of the marking pen. This also fixes the chamfer radius. At this point, simply pulling up the lever causes the positioning rod to rise, disengaging it from the positioning hole. During this disengagement, the reset block compresses the spring. After the positioning rod is removed, the movable plate can be rotated, allowing the marking pen to draw lines on the mold, creating the chamfering path and preventing deviations that could affect the chamfering quality.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution: a high-precision chamfering mold design tool, including an arc-shaped plate 1 and a circular block 5. Connecting rods 6 are welded between the circumferential sidewall of the circular block 5 and the inner wall of the arc-shaped plate 1. Two connecting rods 6 are symmetrically arranged. A rotating column 22 is rotatably connected to the top wall of the circular block 5 via bearings. A movable plate 7 is fitted onto the surface of the rotating column 22, allowing one end of the movable plate 7 to rotate and move around the rotating column 22. A chamfering and scribing mechanism is located in the middle of the movable plate 7. An arc-shaped groove 2 is formed on the top wall of the arc-shaped plate 1. Multiple positioning holes 3 arranged in a circular array are formed on the bottom wall of the groove 2. The positioning mechanism is located on the top wall of the end of the movable plate 7 away from the rotating column 22.

[0021] The chamfering and marking mechanism includes a mounting groove 9 formed on the surface of the movable plate 7. A crossbar 16 is welded between the two side walls of the mounting groove 9. A sliding block 17 is slidably connected to the surface of the crossbar 16, meaning the sliding block 17 can move along the surface of the crossbar 16. A mounting block 18 is welded to the front side wall of the sliding block 17, and a marking pen 19 is mounted on the plate of the mounting block 18 for marking lines. The chamfering and marking mechanism also includes threaded holes 15 evenly formed on the top wall of the movable plate 7. Multiple threaded holes 15 are arranged along the length of the movable plate 7. A fixed plate 20 is welded to the top wall of the sliding block 17. Bolts 21 are threadedly connected to the plate of the fixed plate 20. The bolts 21 are adapted to the threaded holes 15 so that the bolts 21 can be screwed into the threaded holes 15 to position the sliding block 17. The positioning mechanism includes a positioning frame 10 welded to the top right end of the movable plate 7. A positioning rod 12 is disposed within the frame of the positioning frame 10. The top end of the positioning rod 12 extends through the top wall of the positioning frame 10 and is welded with a lever 11. The bottom end of the positioning rod 12 extends through the movable plate 7. The positioning rod 12 is located directly above the positioning hole 3, and its body is fitted into the cavity of the positioning hole 3. This allows the positioning rod 12 to be inserted into the cavity of the positioning hole 3, preventing the movable plate 7 from rotating. A reset block 13 and a spring 14 are disposed within the frame of the positioning frame 10. The reset block 13 is welded and sleeved on the surface of the positioning rod 12, and the spring 14 is sleeved on the surface of the positioning rod 12, with the spring 14 located at the top of the reset block 13. An anti-detachment block 8 is welded to the top of the rotating column 22 to prevent the movable plate 7 from detaching from the rotating column 22. The conical groove 4 is formed on the inner wall of the arc plate 1, and its purpose is to facilitate the placement of the mold to be scribed.

[0022] In use, by placing the chamfered end of the mold to be chamfered against the tapered groove 4, the bolt 21 can be unscrewed from the threaded hole 15, allowing the sliding block 17 to move along the crossbar 16. This allows for quick adjustment of the chamfer radius, enabling chamfering within multiple radius ranges. Once the chamfer radius is set, the bolt 21 can be screwed back into the threaded hole 15 to position and fix the marking pen 19, thus fixing the chamfer radius. At this point, simply pull up the lever 11, causing it to lift the positioning rod 12, which then moves it out of the positioning hole 3. As the positioning rod 12 moves out of the positioning hole 3, the reset block 13 compresses the spring 14. After the positioning rod 12 is removed, the movable plate 7 can be rotated around the rotating column 22, allowing the marking pen 19 to mark lines on the mold, creating the chamfering path and preventing deviations that could affect the chamfering quality.
