[0022] like Figure 1As shown, the tool dust removal structure is installed beside the tool 10 of the machining equipment. The machining equipment is provided with a spindle 20 for clamping a tool handle 11 of the tool 10, and the tool body 12 of the tool 10 faces the workpiece; the dust removal structure is installed on the spindle 20, including a positioning member 30 and a plurality of nozzles 40, the positioning member 30 is an annular structure and is detachably fixed to the end of the spindle 20 facing the workpiece and is provided on the periphery of the tool 10, and a plurality of nozzles 40 are detachably fixed thereon, the open end of each nozzle 40 faces the tool 10, and the other end can be connected to the ventilation pipe 50, and the ventilation pipe 50 is connected to an air pump; when installing and removing the tool, the air pump inputs positive air pressure or reverse air pressure into each nozzle 40 through the ventilation pipe 50 to blow or inhale toward the tool 10 to remove foreign matter adsorbed on the tool handle 11 and / or the tool body 12.

[0023] When replacing a new tool, when the tool holder 11 is close to the spindle 20, the air pump generates positive or negative pressure. The positive pressure gas blown out by the nozzle 40 can blow off foreign matter such as dust and waste chips adsorbed on the tool holder 11. The negative pressure in the nozzle 40 can adsorb foreign matter on the isolation net between the nozzle 40 and the tool 10 to prevent it from splashing into the spindle, ensuring that the tool holder 11 is installed in the spindle 20 and maintains a high degree of cleanliness, avoiding or reducing vibration or position deviation caused by foreign matter during the rotary cutting process of the tool 10, and thereby helping to improve the processing accuracy of the tool 10. When the tool holder 11 is grasped and fixed by the spindle 20, the positive or negative pressure gas in the nozzle 40 can continuously clean the tool body 12, ensuring that the cutting portion thereon remains clean.

[0024] During use, air can be blown or sucked toward the tool 10 through the nozzle 40 according to actual conditions, and a filter chamber can be provided in between to prevent foreign matter removed from the tool 10 from splashing into the nozzle or the spindle 20. The structure of the spindle 20 and the working principle of clamping and fixing the tool handle 11 are common knowledge to those skilled in the art, and the specific structure of the spindle will not be described in detail here.

[0025] like Figure 2 As shown, the positioning member 30 includes a matching outer positioning ring 31 and an outer sealing gasket 32. The outer positioning ring 31 is removably fixed to the outer wall of the end of the spindle 20 and is provided with a plurality of positioning holes 33. The spindle 20 is provided with a plurality of mounting holes 33 that match the positioning holes 33. A plurality of nozzles 40 are circumferentially spaced evenly around the periphery of the tool 10 and are connected to the ventilation line 50 via a connecting line 60.

[0026] like Figure 3As shown, the connecting pipeline 60 includes a loop 61 and a passage 62. The loop 61 is an annular groove coaxial with the inner wall of the outer positioning ring 31 and is provided at the end of the outer positioning ring 31 facing the gasket 32 ​​and is interconnected with each nozzle 40. The gasket 32 ​​is a sealing gasket and a matching cover is provided on the loop 61. One end of the passage 62 is connected to the ventilation pipeline 50, and the other end passes through a side wall of the outer positioning ring 31 and is connected to the loop 61.

[0027] In application, in order to adapt to different tools 10 and facilitate manual tool changing, each nozzle can also be set as a hinged positioning rod and guide rod. The positioning rod is embedded in the outer positioning ring 31 and can rotate relative to it. The guide rod is hinged at its end and facing the tool. When in use, the inclination angle of the guide rod is adjusted as needed.

[0028] like Figure 4 As shown, in another embodiment of the present invention, the connecting pipe 60 is further connected to a cooling pipe 70. A switch 80 is provided at the connection between the connecting pipe 60, the cooling pipe 70, and the ventilation pipe 50. The switch 80 can be a manual or electric valve, which is common knowledge and its structure is not limited or detailed here.

[0029] During cutting processing, coolant can be introduced into the connecting pipe 60 through the cooling pipe 70 according to the actual processing conditions, and the coolant can be sprayed toward the tool body 12 through the nozzle 40 to accelerate the dissipation of heat during cutting and avoid waste chips from flying toward the spindle 20, thereby extending the processing life of the tool 10, reducing the wear of the end of the spindle 20, and thereby improving the processing accuracy.

[0030] like Figure 5 As shown, in another embodiment of the present invention, the spindle 20 is a large spindle structure, and the positioning member 30 includes a matching inner positioning ring 34 and an inner sealing gasket 35. The inner positioning ring 34 is mounted on the inner wall of the housing 21 of the spindle 20. The nozzle 40 on the inner positioning ring 34 can clean foreign matter on the tool holder 11 when it is close to the spindle 10 and before it is clamped in the clamping mechanism of the spindle 20.

[0031] The present invention installs a positioning piece 30 and a nozzle 40 at the end of the spindle 20 for clamping the tool 10. This can automatically remove foreign matter on the tool holder 11 that matches the tool 10 and the spindle 20 before clamping the tool 10, thereby avoiding or reducing vibration or position deviation of the tool 10 caused by foreign matter during the rotational cutting process, and thereby helping to improve the processing accuracy of the tool 10; foreign matter on the tool body 11 can also be cleaned before cutting, and by connecting the nozzle 40 with the cooling pipeline 70, coolant can also be sprayed toward the tool body 12 during cutting to accelerate the dissipation of heat during cutting and avoid waste chips from splashing toward the spindle 20, thereby extending the processing life of the tool 10, reducing the wear of the end of the spindle 20, and thereby improving the processing accuracy.

[0032] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
