[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-2 A cutting device for wear-resistant gears in conveying equipment includes a fixed base 1, a cavity 2 inside the fixed base 1, a hinged sealing door on the rear inner wall of the cavity 2, a small motor 3 fixedly mounted on the bottom of the cavity 2, a rotating rod 4 fixedly connected to the upper end of the drive shaft of the small motor 3, a positioning post 5 fixedly connected to the upper end of the rotating rod 4, the upper end of the positioning post 5 vertically rotating through the top surface of the cavity 2, a clamping mechanism on the annular side wall near the upper end of the positioning post 5, the clamping mechanism including two symmetrically distributed circular grooves 7 on the annular side wall near the upper end of the positioning post 5, springs 8 fixedly connected to the opposite inner walls of the two circular grooves 7, and the ends of the two springs 8 away from the inner walls of the circular grooves 7 fixedly connected to... There are two movable rods 9, and the annular sidewalls of the two movable rods 9 slide in contact with the annular inner wall of the circular groove 7. The ends of the two movable rods 9 located outside the circular groove 7 are fixedly connected to arc-shaped abutments 10. The sidewalls of the two arc-shaped abutments 10 away from the movable rods 9 are provided with arc-shaped slopes 11. The wear-resistant gear to be cut is connected to the positioning post 5 on the fixed seat 1, so that the inner ring of the gear abuts in contact with the two arc-shaped abutments 10. After the arc-shaped slopes 11 of the two arc-shaped abutments 10 contact the inner ring of the gear, the movable rods 9 are driven to compress the spring 8 in the circular groove 7. The spring 8, together with the movable rods 9, drives the two arc-shaped abutments 10 to clamp and position the gear on the positioning post 5, which is convenient for quick positioning and easy replacement, and improves cutting efficiency.

[0021] Two movable rods 9 are fitted with sealing rings 12 at their ends outside the circular groove 7. Both sealing rings 12 are fixedly connected to the annular sidewall of the positioning post 5. Several arc-shaped limiting strips 13 are fixedly connected to the opposing sidewalls of the two arc-shaped abutments 10 near their lower ends. When the inner ring of the gear comes into contact with the two arc-shaped abutments 10, the arc-shaped slopes 11 of the two arc-shaped abutments 10 contact the inner ring of the gear, causing the movable rods 9 to compress the spring 8 inside the circular groove 7 until the inner ring of the gear abuts and is pressed tightly against the several arc-shaped limiting strips 13 on the arc-shaped abutments 10. The sealing rings 12 and the arc-shaped limiting strips 13 are both made of wear-resistant rubber. The several arc-shaped limiting strips 13 made of wear-resistant rubber prevent the gear from easily detaching from the arc-shaped abutments 10, and the sealing rings 12 prevent… Impurities enter the circular groove 7. A frustum-shaped collecting cover 6 is fitted onto the fixed base 1. A cylindrical protrusion 14 is provided at the lower end of the center of the fixed base 1. An external thread 15 is provided on the annular side wall of the cylindrical protrusion 14 near the lower end.

The frustum-shaped collecting cover 6 is manually rotated so that the external thread 15 is threadedly connected to the circular threaded opening 16, which facilitates the disassembly of the frustum-shaped collecting cover 6 and allows the cutting debris to be guided into the frustum-shaped collecting cover 6 for collection, thus collecting the cutting debris in a timely manner.

[0022] In use, the wear-resistant gear to be cut is aligned with the positioning post 5 on the fixed base 1, so that the inner ring of the gear abuts against two arc-shaped blocks 10. After the arc-shaped slope 11 of the two arc-shaped blocks 10 contacts the inner ring of the gear, it drives the movable rod 9 to compress the spring 8 in the circular groove 7 until the inner ring of the gear abuts against several arc-shaped limiting strips 13 on the arc-shaped blocks 10. Thus, the spring 8, together with the movable rod 9, drives the two arc-shaped blocks 10 to clamp and position the gear on the positioning post 5, which is convenient and quick. The device is quick to position and easy to replace, improving cutting efficiency. The small motor 3 in the cavity 2 drives the clamping and positioning gear to rotate slowly. Adjust the cutting position of the gear and fit the frustum-shaped collection cover 6 onto the fixed base 1, so that the cylindrical protrusion 14 is inserted into the circular threaded opening 16. Manually rotate the frustum-shaped collection cover 6 so that the external thread 15 is threadedly connected to the circular threaded opening 16, which facilitates the disassembly of the frustum-shaped collection cover 6 and allows the cutting debris to be guided into the frustum-shaped collection cover 6 for collection, thus collecting the cutting debris in a timely manner.
