Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1
[0024] As Figures 1 to 4 shown, a chamfering tool with a multi-purpose chamfering blade includes a tool rod 1. An infusion hole 2 is provided at the other end of the tool rod 1. One end of the infusion hole 2 communicates with a liquid groove 3. A partition board 4 is fixed inside the liquid groove 3. A first through hole 5 is provided inside the partition board 4. A swivel ring 6 is arranged on the outer wall of the tool rod 1. A threaded hole 8 is provided inside the swivel ring 6. Second through holes 7 are arranged on both sides of the threaded hole 8. A screw 9 is threadedly connected inside the threaded hole 8. A sealing gasket 10 is fixed at one end of the screw 9. By rotating the swivel ring 6, the screw 9 moves so that the second through hole 7 can communicate. Then, the coolant can be input into the liquid groove 3 through the infusion hole 2, and through the first through hole 5 and the second through hole 7 on the partition board 4, it is convenient to circulate the coolant between the swivel ring 6 and the tool head rod 11;
[0025] One end of the tool shank 1 is fixed with a tool head shank 11. An accommodation groove 12 is formed inside one end of the tool head shank 11, and a circulation groove 13 is formed on the outer wall of the tool head shank 11. Through the circulation groove 13 on the tool head shank 11, it is convenient for the coolant to flow to the multi-purpose cutting blade 19 to cool the multi-purpose cutting blade 19. Embodiment Two
[0026] In this embodiment, in addition to including all the technical features in Embodiment One, it further includes:
[0027] The liquid tank 3 and the circulation groove 13 form a communication structure through the first through hole 5 and the second through hole 7. A rotating structure is formed between the rotating ring 6 and the tool shank 1. By rotating the rotating ring 6, the screw rod 9 in the threaded hole 8 of the rotating ring 6 is moved to open the second through hole 7, facilitating the flow of the coolant. Through the infusion hole 2, the liquid tank 3, the first through hole 5, and the second through hole 7, it is convenient to input the coolant into the tool head shank 11 to cool the multi-purpose cutting blade 19 on the tool head shank 11, preventing the temperature of the cutting edge of the multi-purpose cutting blade 19 from rising rapidly after long-term use, damaging the cutting edge of the multi-purpose cutting blade 19, and extending the service life of the multi-purpose cutting blade 19.
[0028] The screw rod 9 and the rotating ring 6 form a sliding structure through the threaded hole 8. The sealing gasket 10 and the screw rod 9 are adhesively connected. By driving the sealing gasket 10 to move through the screw rod 9, it is convenient to control the flow state of the second through hole 7, and the sealing gasket 10 can prevent the coolant from flowing out when the second through hole 7 is in a sealed state.
[0029] A chip removal groove 14 is formed at the other end of the tool head shank 11, and a protection plate 16 is arranged inside the chip removal groove 14. The multi-purpose cutting blade 19 can be protected and fixed through the protection plate 16.
[0030] A tool groove 15 is arranged at the bottom of the protection plate 16, and a multi-purpose cutting blade 19 is arranged inside the tool groove 15. The multi-purpose cutting blade 19 can be installed through the tool groove 15.
[0031] A cutting edge 21 is arranged on one side of the multi-purpose cutting blade 19, and a chamfering edge 20 is arranged at one end of the cutting edge 21. Fixing holes 17 are formed on the outer surface of the protection plate 16, and fixing bolts 18 are threadedly connected inside the fixing holes 17. The surface of the multi-purpose cutting blade 19 is provided with a cutting edge 21 and a chamfering edge 20. The cutting edge 21 on the multi-purpose cutting blade 19 is used to cut the workpiece through the chamfering tool, and then chamfering processing is carried out through the chamfering edge 20, realizing the functions of cutting and chamfering simultaneously.
[0032] The multi-purpose blade 19 forms a detachable structure with the tool groove 15 through the fixing bolt 18 and the fixing hole 17. The guard plate 16 and the chip removal groove 14 are integrally fixed. The multi-purpose blade 19 is detachable from the tool groove 15, which is convenient for replacing the damaged multi-purpose blade 19. And through the cutting edge 21 and the chamfering edge 20 on the multi-purpose chamfering blade 19, the workpiece is cut and chamfered, realizing the functions of cutting and chamfering at the same time. The guard plate 16 can protect and fix the multi-purpose blade 19, and can prevent chips from getting stuck between the multi-purpose blade 19 and the chip removal groove 14.
[0033] Working principle: Before using the chamfering tool, place the multi-purpose blade 19 into the tool groove 15 between the guard plate 16 and the tool head rod 11, and fix the multi-purpose blade 19 through the fixing hole 17 and the fixing bolt 18. When the chamfering tool processes the workpiece, the cutting edge 21 on the multi-purpose chamfering blade 19 cuts the workpiece, and then the chamfering edge 20 is used for chamfering, realizing the functions of cutting and chamfering at the same time. When the chamfering tool processes the workpiece, rotate the rotating ring 6 on the outer surface of the tool rod 1. The rotating ring 6 and the threaded hole 8 inside it rotate, so that the screw rod 9 moves inside the threaded hole 8 and the receiving groove 12, moving the sealing gasket 10 towards one end of the partition plate 4 to ensure that the second through hole 7 is no longer airtight. At the same time, the partition plate 4 abuts against the screw rod 9 to prevent the screw rod 9 from moving out of the threaded hole 8. Then, during the processing, input the coolant into the liquid infusion hole 2, so that it flows to one end of the liquid tank 3, and then through the first through hole 5 on the partition plate 4, the coolant flows to the bottom of the liquid tank 3, and the coolant flows to the space between the rotating ring 6 and the tool head rod 11 through the no-longer airtight second through hole 7. Then, through the flow groove 13 on the outer surface of the tool head rod 11, the coolant flows to the multi-purpose blade 19 to cool the two cutting edges on the multi-purpose blade 19, preventing the temperature of the cutting edges of the multi-purpose blade 19 from rising rapidly after long-term use, causing damage to the cutting edges of the multi-purpose blade 19, and extending the service life of the multi-purpose blade 19. When the chamfering tool processes the workpiece, the generated chips are discharged through the chip removal groove 14.
