[0036] Reference Figure 1-Figure 3 The axial feed assembly includes two axial slide rails 6 and an axial movable seat 7. The axial slide rails 6 are symmetrically fixedly connected to the base 5. A plurality of axial sliders 8 are fixedly connected to the side of the axial movable seat 7 close to the base 5. The axial sliders 8 are slidably connected to the axial slide rails 6. An axial drive motor 9 and a plurality of first mounting seats 10 are fixedly connected to the base 5. An axial ball screw 11 rotatably connected to the first mounting seat 10 is fixedly connected to the output end of the axial drive motor 9. The circumferential feed assembly includes two groups of circumferential slide rails 15 and a circumferential movable seat 16. The circumferential slide rails 15 are symmetrically fixedly connected to the axial movable seat 7. A circumferential slider 17 slidably connected to the circumferential slide rails 15 is fixedly connected to the bottom of the circumferential movable seat 16. A circumferential drive motor 18 and a second mounting seat 19 are fixedly connected to the axial movable seat 7. A circumferential ball screw 20 rotatably connected to the second mounting seat 19 is fixedly connected to the output end of the circumferential drive motor 18.
[0037] It needs to be explained that the tool is arranged on the circumferential movable seat 16, which is a conventional method in the prior art, so it will not be elaborated. In addition, the shape of the tool is not limited, and the staff can adjust it according to the processing conditions of the workpiece. The bottom of the base 5 is inclined. During the processing, the debris generated will fall onto the base 5 and be concentrated in the center position when it is inclined. Generally, the staff cleans the debris generated by the processing. When processing the workpiece, the axial drive motor 9 or the circumferential drive motor 18 drives the axial ball screw 11 or the circumferential ball screw 20 to rotate, thereby driving the tool to move in different directions to realize the processing of the workpiece.
[0038] Reference Figure 2 , Figure 3 The axial moving seat 7 and the circumferential moving seat 16 are both fixedly connected with a nut assembly 12 matching the axial ball screw 11 and the circumferential ball screw 20. The first mounting seat 10 and the second mounting seat 19 are rotatably connected to the axial ball screw 11 and the circumferential ball screw 20 and are both rotatably connected with a rotating shaft 13. A driving gear set 14 is provided on the rotating shaft 13 and the axial ball screw 11 and the circumferential ball screw 20, wherein the axial ball screw 11 and the circumferential ball screw 20 drive the rotating shaft 13 in the corresponding direction to rotate through the driving gear set 14, and the rotating shaft 13 passes through the nut assembly 12.
[0039] It needs to be explained that the size of the driving gear set 14 arranged on the rotating shaft 13 is smaller than the size of the driving gear set 14 on the axial ball screw 11 and the circumferential ball screw 20, so that the rotation speed of the rotating shaft 13 can be increased when the axial ball screw 11 and the circumferential ball screw 20 rotate. The specific structure of the driving gear set 14 can refer to the technical solutions in the prior art. Those skilled in the art can know that it will not be elaborated here. When the axial ball screw 11 and the circumferential ball screw 20 rotate, they will drive the rotating shaft 13 to rotate through the driving gear set 14.
[0040] Reference Figure 4 The nut assembly 12 includes a nut member 121 which is sleeved on the axial ball screw 11 or the circumferential ball screw 20. A slide groove 122 is provided inside the nut member 121. A moving ring 123 is slidably connected inside the slide groove 122. A steel ball 124 matching the axial ball screw 11 or the circumferential ball screw 20 is provided on the moving ring 123. A reverser 125 connected to the steel ball 124 is provided inside the moving ring 123, wherein the steel ball 124 is in close contact with the axial ball screw 11 or the circumferential ball screw 20.
[0041] When the axial ball screw 11 and the circumferential ball screw 20 rotate, the steel ball 124 will rotate along the axial ball screw 11 and the circumferential ball screw 20. The specific structure of the reverser 125 can refer to the technical solutions in the prior art. Those skilled in the art can know it and will not elaborate on it here. The reverser 125 can ensure the stability of the forward and reverse movement of the tool.
[0042] Reference Figure 4-Figure 5 The control unit includes a plurality of inductive adjustment mechanisms 126 fixedly connected in the slide groove 122, and a spring 127 is sleeved on the outside of the inductive adjustment mechanism 126. The inductive adjustment mechanism 126 includes a fixed cylinder 1261 and a compression rod 1262. The end of the compression rod 1262 extends to the inside of the fixed cylinder 1261, and the end of the compression rod 1262 away from the fixed cylinder 1261 is connected to the moving ring 123. The inner wall of the fixed cylinder 1261 is provided with a resistance ring 1263, and the end of the compression rod 1262 close to the fixed cylinder 1261 is provided with a connecting slider 1264 matching the resistance ring 1263. The outer wall of the fixed cylinder 1261 is provided with an air hole 1265, wherein the resistance ring 1263 and the connecting slider 1264 are electrically connected to the corresponding axial drive motor 9 and circumferential drive motor 18. A lubrication mechanism is also provided on the moving ring 123 for lubricating the steel ball 124 and the axial ball screw 11 and the circumferential ball screw 20.
[0043] When the tool processes the workpiece, it will drive the movable ring 123 to move in the slide groove 122, and at the same time drive the compression rod 1262 to move into the fixed cylinder 1261. When the pressure between the tool and the workpiece reaches a certain value, the connecting slider 1264 will contact the resistance ring 1263, so that the corresponding axial drive motor 9 and the circumferential drive motor 18 will reduce the rotation speed, thereby adjusting the feed speed of the tool. While ensuring the workpiece processing efficiency, it can avoid damage to the tool and the workpiece. In addition, the compression rod 1262 can also compress the gas in the fixed cylinder 1261 and discharge it through the air hole 1265.
[0044] Reference Figure 4 The lubrication mechanism includes an oil storage chamber 128 opened on the side of the movable ring 123 close to the nut member 121, an oil discharge channel 1291 is opened inside the movable ring 123, one end of the oil discharge channel 1291 is connected to the oil storage chamber 128, and the other end of the oil discharge channel 1291 is connected to the steel ball 124, a connecting pipe 129 is arranged inside the nut member 121, and a first pneumatic valve 1290 is arranged on the connecting pipe 129, wherein the outside of the nut member 121 is fixedly connected to an oil tank 21 connected to the connecting pipe 129, and the air hole 1265 is connected to the first pneumatic valve 1290 through a pipeline.
[0045] It needs to be explained that the oil tank 21 is used to store lubricating oil, and the oil tank 21 is in a sealed state. A refueling port is provided on the oil tank 21. When gas is introduced into the oil tank 21, the internal lubricating oil will be driven into the connecting pipe 129 under the action of air pressure. By controlling the opening and closing of the first pneumatic valve 1290, the lubricating oil can enter the oil storage chamber 128, and finally be discharged to the steel ball 124 through the oil discharge channel 1291. When the tool moves at a faster speed, the wear between the steel ball 124 and the nut 121, the axial ball screw 11 and the circumferential ball screw 20 is reduced, thereby extending the service life of the axial ball screw 11, the circumferential ball screw 20 and the steel ball 124.
[0046] Reference Figure 4 The dustproof unit includes a sealing ring 1292 fixedly connected to both ends of the nut member 121, and a cleaning ring 1293 is fixedly connected to one end of the sealing ring 1292 away from the nut member 121, wherein the axial ball screw 11 and the circumferential ball screw 20 pass through the sealing ring 1292 and the cleaning ring 1293, and the cleaning ring 1293 is in contact with the outer side walls of the axial ball screw 11 and the circumferential ball screw 20, and a blowing mechanism is provided on the inner side wall of the sealing ring 1292.
[0047] The sealing ring 1292 is sleeved on the axial ball screw 11 and the circumferential ball screw 20, and a brush is arranged on the cleaning ring 1293 close to the side of the axial ball screw 11 and the circumferential ball screw 20. When the axial ball screw 11 and the circumferential ball screw 20 are rotating, the brush on the cleaning ring 1293 can clean the surface of the axial ball screw 11 and the circumferential ball screw 20, and can clean most of the debris and dust adhering to the axial ball screw 11 and the circumferential ball screw 20.
[0048] Reference Figure 4 , Figure 6 and Figure 7The blowing mechanism includes a reciprocating screw 1296 rotatably connected between the inner wall of the sealing ring 1292 and the nut member 121, a reciprocating slider 1298 is arranged on the reciprocating screw 1296, two sets of compression cylinders 1299 are fixedly connected between the reciprocating slider 1298 and the inner wall of the sealing ring 1292, a connecting shaft 1294 is rotatably connected to the side of the sealing ring 1292 close to the rotating shaft 13, a first bevel gear set 1295 is arranged between the connecting shaft 1294 and the rotating shaft 13, a second bevel gear set 1297 is arranged between the reciprocating screw 1296 and the connecting shaft 1294, and the sealing ring 1292 is close to the axial ball screw 11 and the circumferential ball screw 1294. An exhaust ring 1213 is provided on one side of the screw 20, and a jet ring 1214 is fixedly connected to the inner wall of the sealing ring 1292 close to the axial ball screw 11 and the circumferential ball screw 20.

[0049] When the axial ball screw 11 and the circumferential ball screw 20 rotate, they drive the rotating shaft 13 to rotate, and drive the reciprocating screw 1296 to rotate through the first bevel gear set 1295, the connecting shaft 1294 and the second bevel gear set 1297, and drive the reciprocating slider 1298 to move back and forth, and compress the gas through the compression cylinder 1299. Part of the compressed gas is sprayed to the exhaust ring 1213 through the jet ring 1214, which can clean up smaller particles of dust, debris, etc. (because when the pressure between the tool and the workpiece is large, dust is more likely to enter the ball screw. Therefore, when the pressure between the tool and the workpiece is large, the jet volume can be controlled by the second pneumatic valve 1215 to ensure its dust-proof effect). Part of the compressed gas enters the oil tank 21 through the exhaust pipe 1211, and under the action of the pressure relief valve 1212, the oil tank 21 is in a stable pressure state, thereby ensuring the stability of the lubricating oil supply.
