[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to solve the problem that the existing technology cannot accurately round the corners of the tool side, the following technical solution is provided. Figure 1-5 ;

[0024] A fine processing device for wear-resistant cutting tools comprises a box body 1, a rotating cylinder 2 is provided at the bottom of the box body 1, a rotating plate 3 is provided on the turntable 8 of the rotating cylinder 2, one end of the rotating plate 3 is bolted to the rotating cylinder 2, and a motor 4 is installed on the top of the other end, a partition 5 is fixed at the center position inside the box body 1, an arc groove 6 is opened on the partition 5, the output shaft of the motor 4 passes through the arc groove 6 and is connected to the grinding wheel 7 above the partition 5; the rotating cylinder 2 drives one end of the rotating plate 3 to rotate through the turntable 8, and the other end of the rotating plate 3 drives the motor 4 to rotate accordingly, and the output shaft of the motor 4 drives the grinding wheel 7 to rotate at high speed to grind the corners of the cutting tool.

[0025] The arc groove 6 is semicircular, and the center of the turntable 8 and the center of the arc groove 6 are located on the same axis. Therefore, the grinding wheel 7 also makes a circular motion when rotating. The distance between the grinding wheel 7 and the concave point in the arc groove 6 is adjusted according to the arc length of the fillet that the tool needs to grind. When the fillet arc is larger, the distance between the end face of the tool and the concave point in the arc groove 6 is adjusted closer. When the fillet arc is smaller, the distance between the end face of the tool and the concave point in the arc groove 6 is adjusted farther, thereby adjusting the extent to which the side edge of the tool extends into the motion range of the grinding wheel 7, thereby determining the grinding amount of the tool.

[0026] A through hole 9 and a tool entrance 10 are provided on one side surface of the box body 1. The through hole 9 faces the side of the rotary cylinder 2 where the air pipe is provided. The through hole 9 is used to penetrate the air inlet pipe and the air outlet pipe of the rotary cylinder 2. The air intake and air outlet are precisely controlled by the computer system, so that the turntable 8 can rotate slowly and at a uniform speed, and the grinding wheel 7 can be driven to move slowly and at a uniform speed to grind the side of the tool.

[0027] The tool entrance port 10 faces the concave surface of the arc groove 6, and the tool entrance port 10 and the arc groove 6 are located on the same central axis, so that the grinding amount of the two grinding sides of the tool is equal. A tool clamping and fixing component is provided outside the tool entrance port 10 for fixing the tool during grinding.

[0028] Magnetic sheets 11 are provided on the inner wall of the box body 1 above the partition 5. The magnetic sheets 11 are evenly spaced and can absorb iron filings generated by the grinding wheel 7 during grinding to prevent the iron filings from splattering and rebounding and constantly scratching the surface of the tool, thereby protecting the surface structure of the tool and enhancing the wear resistance of the tool.

[0029] A limiting groove 12 is provided on the top of the box body 1. The limiting groove 12 has the same shape and size as the arc groove 6. The positions of the limiting groove 12 and the arc groove 6 correspond to each other in vertical direction. A limiting block 13 is provided on the top of the limiting groove 12. A bearing 14 is provided in the limiting block 13. The top of the rotating shaft of the grinding wheel 7 passes through the inner ring of the bearing 14 and is fixed to the inner ring. When the grinding wheel 7 rotates, the rotating shaft rotates accordingly in the bearing 14. When the grinding wheel 7 moves, the limiting groove 12 and the limiting block 13 can make it move stably, thereby preventing the grinding wheel 7 from having a slight inclination angle and making the grinding fillet irregular.

[0030] An observation window 15 is provided on the top of the box body 1. Two observation windows 15 are provided and are respectively located on both sides of the limiting groove 12. Through the observation windows 15, the staff can observe the internal grinding situation in real time.

[0031] Working principle: Place the tool into the tool entrance 10, and move the two side edges to be polished to the concave part of the arc groove 6, start the motor 4 to drive the grinding wheel 7 to rotate at high speed to polish the side corners of the tool, and while polishing, the rotating cylinder 2 drives one end of the rotating plate 3 to rotate slowly through the turntable 8, and the other end of the rotating plate 3 drives the motor 4 to rotate accordingly, and accordingly drives the grinding wheel 7 to make a circular motion with the arc groove 6 as the trajectory, thereby grinding the side of the tool into a rounded corner.
