Description

Technical Field

[0001] This invention relates to the field of drill bit processing technology, and more specifically, to a drill bit cooling device for geological drilling. Background Technology

[0002] Geological drilling bits are crucial tools for breaking underground rock formations, and their carbide or diamond cutting teeth must possess extremely high wear resistance and strength. To ensure dimensional accuracy and thread quality, high-strength CNC lathes must be used for machining. These specialized lathes feature high rigidity, high-pressure cooling systems, and precision control systems, enabling them to handle the machinability of drill bit materials and guarantee the reliability and service life of the drill bits under complex geological conditions.

[0003] A patent application with publication number CN115302320B discloses a drill bit processing device and process, including a turntable and a grooving grinding wheel, an edge-cleaning grinding wheel, and an open-back-angle grinding wheel arranged equidistantly in a ring on the turntable. The turntable also has a feeding device corresponding to the open-back-angle grinding wheel. Three drill bit clamping assemblies are arranged on the outer side of the turntable, corresponding sequentially to the grooving grinding wheel, edge-cleaning grinding wheel, and open-back-angle grinding wheel. The turntable drives the grooving grinding wheel, edge-cleaning grinding wheel, and open-back-angle grinding wheel to rotate synchronously, allowing them to simultaneously process the drill bit clamped in the three clamping assemblies. The drill bit clamped in the three clamping assemblies is processed sequentially by the grooving grinding wheel, edge-cleaning grinding wheel, and open-back-angle grinding wheel, and the three processing processes are performed simultaneously. Using this processing method, the drill bit is clamped only once during each processing cycle, improving and maintaining processing efficiency.

[0004] During the use of the above-mentioned device, although it can perform multiple processing steps on the workpiece, when turning the drill bit, the metal cut off may adhere to the surface of the turning tool due to the influence of temperature and coolant. It cannot be washed away by coolant alone. During the next turning operation, it may cause the tool head to vibrate and crack, and may also cause damage to the surface of the workpiece. Summary of the Invention

[0009] As a further optimization of the present invention, the second connecting member includes a connecting tube fixedly installed in a linear array at the bottom of the U-shaped fixing frame. A hollow gear plate is slidably installed inside the connecting tube. An inner sliding tube is fixedly installed at the bottom of the hollow gear plate.

[0012] As a further optimization of the present invention, the rotating component includes a third U-shaped plate fixedly installed on the outside of the fixed frame on the side away from the second U-shaped plate, a third telescopic rod fixedly installed on the side of the third U-shaped plate, a fourth U-shaped plate fixedly installed at the end of the third telescopic rod on the side away from the third U-shaped plate, a third spring provided on the outside of the third telescopic rod, and the fourth U-shaped plate connected to the next grinding component.

This flushes the outer wall of the ground workpiece after grinding, facilitating cooling and cleaning. The rotation of the grinding workpiece grinds the top of the first cutting tool, preventing cutting chips from adhering to the top of the first cutting tool and affecting the subsequent cutting effect, thus improving safety during cutting.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0020] like Figures 1 to 2As shown in the embodiment of the present invention, a drill bit cooling device for geological drilling includes a lathe 1, on which two clamps 11 are provided. A first drill bit 12 is held inside the clamps 11. A cutting tool mounting part 13 is threaded inside the lathe 1. A first cutting tool 14 is provided on the top of the cutting tool mounting part 13. A grinding device 2 is provided on the first cutting tool 14. The first cutting tool 14 is used to process the first drill bit 12. The grinding device 2 is used to grind and cool the iron filings adhering to the top of the first cutting tool 14. like Figures 3 to 4 As shown, the grinding device 2 includes a first fixed plate 21, a first telescopic rod 22, a U-shaped fixing frame 24, a second connecting piece 25, a draining piece 26, and a grinding piece 27. The first fixed plate 21 is fixedly installed on the top of the first cutting tool 14, and the first telescopic rod 22 is fixedly installed on the side of the first fixed plate 21. The grinding piece 27 is rotatably installed on the first telescopic rod 22, and the draining piece 26 is sleeved on the outside of the grinding piece 27. The U-shaped fixing frame 24 is fixedly installed on the top of the first telescopic rod 22, and the second connecting piece 25 is provided at the bottom of the U-shaped fixing frame 24. The grinding piece 27 is used to grind the top of the first cutting tool 14. The second connecting piece 25 communicates with the draining piece 26 to cool the top of the first cutting tool 14 and the first drill bit 12.

[0021] It should be noted that during the machining process, the first drill 12 rotates and contacts the first cutting tool 14, thereby machining the end of the first drill 12. Machining produces iron chips, which are generally in strip or block shape. When the machining is almost finished, the iron chips will fall off. Due to the high temperature during machining and the influence of the coolant, the strip or block iron chips may get stuck at the top cutting position of the first cutting tool 14. When the next round of cutting is performed, the iron chips will come into contact with the cutting position on the first cutting tool 14 and the outside of the first drill 12, resulting in jamming or vibration. If the first drill 12 is in a state of high rotation, it will cause vibration and tool breakage. In order to solve this problem, the following improvements have been made. First, the first drill bit 12 is placed inside the two clamps 11. Then, the clamps 11 are activated to rotate the first drill bit 12. By controlling the position of the tool mounting piece 13, the first cutting tool 14 is moved, allowing the cutting edge on the first cutting tool 14 to cut the end of the first drill bit 12. High temperatures are generated during the cutting process, so a grinding device 2 is installed on the top of the first cutting tool 14. A coolant pipe is connected to the second connector 25, allowing the coolant to contact the top of the first cutting tool 14 and flow from the top of the first cutting tool 14 towards the cutting edge. Then, a motor drives the grinding piece 27 to rotate. A gap exists between the grinding piece 27 and the first cutting tool 14, so the rotation of the grinding piece 27 does not grind the top of the first cutting tool 14. The grinding component 27 is installed inside the first telescopic rod 22. As the grinding component 27 rotates, coolant flows through the second connector 25 into the guide component 26. Guided by the grinding component 27, it moves towards the cutting edge of the first drill bit 12, thus acting as a guide. However, due to the coolant and high temperature, the cut metal chips at the top of the first cutting tool 14 may adhere to its top, affecting subsequent cutting. Therefore, after the first cutting tool 14 has finished cutting the first drill bit 12, the first telescopic rod 22 can be activated to move the entire grinding device 2 towards the centerline of the first drill bit 12. A torsion spring is provided at the connection between the guide component 26 and the first telescopic rod 22 to maintain a constant distance between them. Figure 3In this state, when it is necessary to rotate the guide member 26, the coolant flushed inside the second connector 25 can be pressurized, thereby increasing the flow rate of the coolant inside the second connector 25. During the movement of the first telescopic rod 22 driving the grinding part 27, the surface of the first lathe tool 14 can be ground. The second connector 25 is equipped with fan blades. Due to the increased flow rate of the coolant inside the second connector 25, the fan blades inside can be driven to rotate, thereby overcoming the force of the torsion spring at the connection position between the first telescopic rod 22 and the guide member 26, thus driving the second connector 25 to rotate. The rotation of the second connector 25 can drive the guide member 26 to rotate clockwise (viewed from the direction of the motor connector 23 towards the grinding part 27). After the guide member 26 has rotated 90°, it stops rotating. During the movement, the other end of the second connector 25 is connected to the guide member 26, thereby cleaning the iron filings ground on the outside of the grinding part 27. This device is designed to prevent iron filings from adhering to the top of the first cutting tool 14, which could affect subsequent cutting. The coolant connected to the second connector 25 also cools the grinding part 27, the first cutting tool 14, and the first drill bit 12. The device connects the second connector 25 to both ends of the guide member 26, thus achieving cooling for the grinding part 27, the first cutting tool 14, and the first drill bit 12. By adjusting the flow rate and pressure of the coolant inside the second connector 25, the internal fan blades of the second connector 25 rotate, causing the second connector 25 to rotate, which in turn causes the guide member 26 to rotate. This flushes the outer wall of the grinding part 27 after grinding, facilitating cooling and cleaning. The rotation of the grinding part 27 grinds the top of the first cutting tool 14, preventing iron filings from adhering to the top of the first cutting tool 14 and affecting subsequent cutting, thereby improving safety during cutting.

[0022] like Figures 2 to 4 As shown, the polishing device 2 includes a motor connector 23 fixedly installed on the side of the first telescopic rod 22. An adapter 28 is fixedly installed on the motor connector 23. The adapter 28 is connected to the polishing component 27. Multiple polishing components 27 are provided on both sides of the first telescopic rod 22. A rotating component 29 is provided between the multiple polishing components 27.

[0023] It should be noted that, considering the need to rotate the grinding element 27, a motor connector 23 is provided on the side of the first telescopic rod 22 to rotate the grinding element 27. Since the iron filings adhering to the top of the first cutting tool 14 may be located in one place, if the grinding element 27 is just a single rod during grinding, it may cause the grinding element 27 to lift up. When the grinding element 27 lifts up, only the iron filings at the highest point of the top of the first cutting tool 14 can be ground. Therefore, multiple grinding elements 27 are provided between the first telescopic rods 22, and the grinding elements 27 are connected by a rotating component 29. The first telescopic rod 22 and the grinding elements 27 are connected by an adapting component 28. When the motor connector 23 rotates, it can rotate the grinding element 27, and the grinding element 27 can adapt to multiple protrusions on the top of the first cutting tool 14, thereby achieving grinding effects at different positions.

[0024] like Figure 4 As shown, the motor connector 23 includes a first fixing rod 231 fixedly installed on the side of the first telescopic rod 22, a second fixing plate 232 fixedly installed at the end of the first fixing rod 231, a first motor 233 fixedly installed inside the second fixing plate 232, and the first motor 233 passing through the first telescopic rod 22 and connected to the rotating component 29.

[0025] It should be noted that the output shaft of the first motor 233 passes through the inside of the guide 26 and is connected to the adaptor 28. Therefore, when the first motor 233 is started, it can drive the grinding part 27 to rotate, thereby achieving the effect of grinding the iron filings adhering to the top of the first cutting tool 14.

[0026] like Figure 3 and Figure 6 As shown, the second connector 25 includes a connecting tube 251 linearly arrayed and fixedly installed at the bottom of the U-shaped bracket 24. A hollow gear plate 254 is slidably installed inside the connecting tube 251. An inner sliding tube 253 is fixedly installed at the bottom of the hollow gear plate 254. A first spring 252 is fixedly installed at the top of the inner sliding tube 253. The bottom of the inner sliding tube 253 cooperates with the draining member 26 to cool the first cutting tool 14 and the first drill bit 12.

[0027] It should be noted that the coolant pipe is connected to the connecting pipe 251, which passes through the U-shaped fixing bracket 24. The connecting pipe 251, the inner sliding tube 253, and the hollow gear plate 254 are all hollow, so the coolant can flow from the connecting pipe 251 to the inner sliding tube 253, and then connect to the hole at the top of the guide member 26, thus flowing to the top of the first cutting tool 14 through the guide member 26. The bottom of the inner sliding tube 253 is rounded. When the guide member 26 rotates, the bottom of the inner sliding tube 253 slides outside the guide member 26. The connecting pipe 251 is equipped with fan blades, so when... When the internal pressure of the connecting pipe 251 is increased, thereby accelerating the flow rate of the coolant, it can drive the fan blades inside the connecting pipe 251 to rotate, which in turn drives the inner slide pipe 253 to rotate. This allows the inner slide pipe 253 to overcome the force of the torsion spring between the first telescopic rod 22 and the guide member 26, thereby driving the guide member 26 to rotate. When the guide member 26 rotates 90°, the fan blades inside the connecting pipe 251 stop rotating again due to the effect of the gear teeth inside the guide member 26, until the first telescopic rod 22 resets, and the flow rate of the coolant inside the connecting pipe 251 is reduced again, thus achieving the effect of resetting the guide member 26.

[0028] like Figures 3 to 5 As shown, the adaptor 28 includes a first U-shaped plate 281 fixedly mounted on the output shaft of the first motor 233, a first adaptor plate 282 rotatably mounted inside the first U-shaped plate 281, a second telescopic rod 283 fixedly mounted on the side of the first adaptor plate 282, a second U-shaped plate 284 fixedly mounted at the end of the second telescopic rod 283, a second spring 285 provided outside the second telescopic rod 283, and the interior of the second U-shaped plate 284 rotatably connected to the grinding component 27.

[0029] It should be noted that when the output shaft of the first motor 233 rotates and drives the first U-shaped plate 281 to rotate, it can drive the first adapting plate 282, the second telescopic rod 283, and the second U-shaped plate 284 to rotate. The rotation of the second U-shaped plate 284 drives the grinding part 27 to rotate, thereby enabling the grinding part 27 to grind the blocky iron filings adhering to the top of the first cutting tool 14.

[0030] like Figures 3 to 5 As shown, the grinding component 27 includes a fixed frame 273 rotatably mounted on the outside of the second U-shaped plate 284. A third fixed plate 272 is fixedly mounted on the outside of the fixed frame 273. A first grinding ring 271 is fixedly mounted on the outside of the third fixed plate 272. The two sides of the fixed frame 273 are symmetrical about the third fixed plate 272.

[0031] It should be noted that a rotating component 29 is rotatably mounted on the side of the fixed frame 273 away from the second U-shaped plate 284. The two fixed frames 273 are connected by the rotating component 29. Therefore, when the fixed frame 273 rotates, it drives the rotating component 29 to rotate, which in turn drives the other grinding component 27 to rotate. Both the grinding component 27 and the rotating component 29 are equipped with springs. Therefore, during the rotation of the first grinding ring 271, the first grinding ring 271 is allowed to be at different heights because of the different heights of the blocky iron filings adhering to the top of the first cutting tool 14. This allows the first grinding ring 271 to grind the iron filings adhering to multiple places on the top of the first cutting tool 14.

[0032] like Figure 5 As shown, the rotating component 29 includes a third U-shaped plate 291 fixedly installed on the outside of the fixed frame 273 on the side away from the second U-shaped plate 284, a third telescopic rod 292 fixedly installed on the side of the third U-shaped plate 291, a fourth U-shaped plate 294 fixedly installed at the end of the third telescopic rod 292 on the side away from the third U-shaped plate 291, a third spring 293 provided on the outside of the third telescopic rod 292, and the fourth U-shaped plate 294 connected to the next grinding component 27.

[0033] It should be noted that the third spring 293 can accommodate the height difference between the two first grinding rings 271, so the first grinding rings 271 can accommodate iron filings of different heights, thereby improving the effect of iron filings grinding on the top of the first cutting tool 14.

[0034] like Figures 6 to 7 As shown, the diversion component 26 includes a diversion isolation plate 261 rotatably mounted on the outer wall of the first motor 233. The diversion isolation plate 261 is provided with a plurality of diversion grooves 262, which correspond to the positions of the second connecting member 25. The outer wall of the center of the diversion isolation plate 261 is provided with teeth 263, which are used to engage with the inner sliding tube 253. A nozzle 264 is fixedly installed on the inner wall of the diversion isolation plate 261, and the nozzle 264 corresponds to the position of the diversion isolation plate 261. A plurality of bristles 265 are fixedly installed inside the diversion isolation plate 261. A nozzle 266 is fixedly installed on the upper part of the diversion isolation plate 261. The nozzle 264, the bristles 265, and the nozzle 266 are on the same straight line.

[0035] It should be noted that the drainage isolation plate 261 has multiple drainage grooves 262 on its exterior, and the inner sliding tube 253 can engage with either the upper or lower drainage grooves 262. When the inner sliding tube 253 rotates and engages with the teeth 263, causing the drainage isolation plate 261 to rotate 90°, as... Figure 6As shown, the inner sliding tube 253 engages with the lower drainage groove 262 of the drainage isolation plate 261 (the other end of the drainage component 26 described above is connected), allowing the coolant to flow out from the nozzle 264. This cleans and cools the outside of the first grinding ring 271. The bristles 265 brush the outside of the first grinding ring 271, preventing iron filings from adhering to the outside of the first grinding ring 271. When the inner sliding tube 253 engages with the upper drainage groove 262, the coolant flows out from the nozzle 266. After passing through the first grinding ring 271, the coolant flows from the cutting edge of the first cutting tool 14 to the cutting position of the first drill bit 12, thus achieving a cooling effect.

[0036] like Figure 7 As shown, the inner diameter of the drainage isolation plate 261 is larger than the outer diameter of the first polishing ring 271.

[0037] It should be noted that the inner diameter of the drainage isolation plate 261 is larger than the outer diameter of the first grinding ring 271, so that the rotation of the first grinding ring 271 will not cause friction with the drainage isolation plate 261, thus improving the stability of the device operation.

[0038] like Figures 6 to 7 As shown, the connecting pipe 251 is provided with a fan blade inside, which is used to drive the inner sliding pipe 253 to rotate. The side of the drainage isolation plate 261 is rotatably connected to the side of the first telescopic rod 22. A torsion spring is provided at the connection position between the drainage isolation plate 261 and the first telescopic rod 22.

[0039] It should be noted that the connecting pipe 251 is internally equipped with fan blades, which drive the inner sliding pipe 253 to rotate. The side of the drainage isolation plate 261 is rotatably connected to the side of the first telescopic rod 22. A torsion spring is provided at the connection position between the drainage isolation plate 261 and the first telescopic rod 22. When pressure is applied inside the connecting pipe 251, the fan blades inside the connecting pipe 251 can rotate, thereby driving the inner sliding pipe 253 to rotate. The rotation of the inner sliding pipe 253 engages with the teeth 263, thereby driving the drainage isolation plate 261 to rotate. The torsion spring at the connection position between the drainage isolation plate 261 and the first telescopic rod 22 allows the drainage isolation plate 261 to be in a relatively stable position when the pressure inside the connecting pipe 251 is low. Figure 6 The state.
