[0033] As Figures 1 to 7 shown, a drill bit device 1 for a drilling machine includes a disk block 10 and a replacement assembly 20. The disk block 10 is arranged on the drilling machine, and a perforation 11 is formed on the disk block 10. The replacement assembly 20 includes a collecting disk 21, a rotating block 22, a top block 23, and a number of replacement parts 24.

[0034] It should be noted that the disk block 10 includes a convex column 12 and a round block 13. The convex column 12 is arranged on the drilling machine, and the round block 13 is arranged at the end of the convex column 12 away from the drilling machine. The diameter of the convex column 12 is smaller than that of the round block 13, so that a T-shaped cylinder 221 is formed around the round block 13 relative to the convex column 12. The through hole 11 penetrates through the convex column 12 and the round block 13, and the through hole 11 is communicated with the inside of the drilling machine. A first rotating surface 131 is arranged on the side of the round block 13 away from the convex column 12. The first rotating surface 131 spirally protrudes in a propeller shape around the through hole 11 for one circle, so that a raised step is formed on the round block 13. Further, a round groove 211 is formed in the collecting disk 21. The round groove 211 is formed centered on the axis of the collecting disk 21. A through hole is formed in the round groove 211, and the diameter of the round groove 211 is larger than that of the through hole, so that a convex platform is formed around the round groove 211 relative to the through hole. Further, the aperture of the through hole is adapted to the diameter of the convex column 12. When the collecting disk 21 is sleeved on the convex column 12 and the collecting disk 21 is located between the drilling machine and the round block 13, the round block 13 is located in the round groove 211, and the peripheries of the round block 13 and the round groove 211 are abutted against each other, so that the collecting disk 21 can be suspended on the drilling machine and can rotate at the same time.

[0035] As Figures 1 to 4 shown, in one embodiment, a plurality of sliding grooves 212 are further formed in the collecting disk 21. One end of each sliding groove 212 is communicated with the through hole, and each replacement part 24 is slidably arranged in each sliding groove 212 in a one-to-one correspondence.

[0036] It should be noted that each sliding groove 212 has a T-shaped structure. One end of each sliding groove 212 is circumferentially distributed around the axis of the round groove 211, and one end of each sliding groove 212 close to the round groove 211 is communicated with the round groove 211. Further, a replacement part 24 is slidably arranged in each sliding groove 212. Since each sliding groove 212 is communicated with the round groove 211, the replacement parts 24 in each sliding groove 212 can slide from the sliding groove 212 into the round groove 211.

[0037] As Figures 1 to 2 、 Figure 4 shown, in one embodiment, one end of the rotating block 22 passes through the through hole 11 and is connected to the driving shaft of the drilling machine, so that the driving shaft of the drilling machine drives the rotating block 22 to rotate.

[0038] It should be noted that the rotating block 22 includes a cylinder 221 and a circular base 222. The cylinder 221 passes through the perforation 11 on the disc block 10 and is connected to the drive shaft of the drilling machine. The circular base 222 is arranged at the end of the cylinder 221 away from the drive shaft of the drilling machine, so that the drive shaft of the drilling machine can drive the rotating block 22 to rotate. Further, a second rotating surface 2221 is arranged on the side surface of the circular base 222 facing the cylinder 221. The second rotating surface 2221 is adapted to the first rotating surface 131, so that a raised step is also formed on the second rotating surface 2221. When the cylinder 221 of the rotating block 22 is inserted into the perforation 11 on the disc block 10, the rotating block 22 and the disc block 10 can slide coaxially closer to or away from each other. Thus, when the rotating block 22 slides closer to the disc block 10, the second rotating surface 2221 will fit along the first rotating surface 131, so that the rotating block 22 rotates along the first rotating surface 131. When the step on the second rotating surface 2221 rotates to abut against the step on the first rotating surface 131, the rotating block 22 cannot rotate, and at this time, the rotating block 22 is docked at a specified position.

[0039] As Figure 2 , Figures 4 to 6 shown, in one embodiment, the rotating block 22 is provided with a material placing groove 2222. The drive shaft of the drilling machine drives the rotating block 22 to rotate, so that the material placing groove 2222 communicates with one of the sliding grooves 212.

[0040] It should be noted that since the circular block 13 on the disc block 10 is located in the circular groove 211, and a first rotating surface 131 is arranged on the side surface of the circular block 13 away from the drilling machine. When the drive shaft of the drilling machine drives the rotating block 22 to rotate and approach the disc block 10, the second rotating surface 2221 on the circular base 222 approaches the first rotating surface 131 on the circular block 13. When the second rotating surface 2221 is completely fitted to the first rotating surface 131, the rotating block 22 is completely accommodated in the circular groove 211. Further, a material placing groove 2222 is provided on the circular base 222. The shape of the material placing groove 2222 is the same as that of the sliding groove 212, both of which are T-shaped structures. After the circular base 222 is completely accommodated in the circular groove 211, the material placing groove 2222 can communicate with one of the sliding grooves 212, so that the replacement part 24 in one of the sliding grooves 212 can slide from the sliding groove 212 into the material placing groove 2222. Further, when a replacement part 24 slides into the material placing groove 2222, the drive shaft of the drilling machine will drive the rotating block 22 away from the disc block 10, and then the rotating block 22 drives the replacement part 24 away from the collecting disc 21.

[0041] As Figures 5 to 6 shown, in one embodiment, the rotating block 22 is provided with a locking hole 2223 and a top hole 2224. The locking hole 2223 extends from the side surface of the rotating block 22 away from the disc block 10 to the inside of the material placing groove 2222, and the top hole 2224 extends from the side surface of the rotating block 22 away from the disc block 10 to the second rotating surface 2221.

[0042] It should be noted that the material placing groove 2222 is of a T-shaped structure, and the lock hole 2223 extends from the side surface of the circular seat 222 away from the cylinder 221 into the material placing groove 2222, and the top hole 2224 extends from the side surface of the circular seat 222 away from the cylinder 221 to the second rotating surface 2221. Further, a connecting groove is formed on the side surface of the circular seat 222 away from the cylinder 221, and the two ends of the connecting groove are respectively communicated with the lock hole 2223 and the top hole 2224. Thus, the lock hole 2223, the connecting groove and the top hole 2224 together form a U-shaped hole structure.

[0043] As Figure 4 shown, in an embodiment, the top block 23 is of a U-shaped structure. One end of the top block 23 is slidably arranged in the lock hole 2223 to extend into the material placing groove 2222, and the other end of the top block 23 is slidably arranged in the top hole 2224 to extend out from the second rotating surface 2221.

[0044] It should be noted that the top block 23 is adapted to the U-shaped hole structure formed by the lock hole 2223, the connecting groove and the top hole 2224, so that the top block 23 can be inserted into the U-shaped hole structure. Further, one end of the top block 23 is slidably arranged in the lock hole 2223 to extend into the material placing groove 2222, and the other end of the top block 23 is slidably arranged in the top hole 2224 to extend out from the second rotating surface 2221. Since the top block 23 is an integral structure, the two ends of the top block 23 sliding in the lock hole 2223 and the top hole 2224 slide synchronously. For example, when one end of the top block 23 extending out from the second rotating surface 2221 is externally pressed, the top block 23 will be extruded to extend out from the side surface of the circular seat 222 away from the cylinder 221, and at the same time, the end extending into the material placing groove 2222 will also be synchronously pulled out of the material placing groove 2222.

[0045] As Figures 4 to 6 shown, in an embodiment, the replacement component 20 further includes a spring 25. The spring 25 respectively pushes the rotating block 22 and the top block 23 to make the end of the top block 23 located in the material placing groove 2222 clamp the replacement part 24.

[0046] It should be noted that a top platform 2225 is further provided on a side surface of the circular base 222 away from the cylinder 221. The top platform 2225 is located at one end of the top hole 2224. When the top hole 2224 extends from the second rotating surface 2221, it extends into the top platform 2225. The spring 25 is located in the top platform 2225, and the spring 25 respectively pushes against the inner side wall of the top platform 2225 and the top block 23, so that one end of the top block 23 extends into the material placing groove 2222 and the other end extends out from the second rotating surface 2221. Further, when one end of the top block 23 extending out from the second rotating surface 2221 is externally squeezed, the top block 23 squeezes the spring 25, and further makes the end of the top block 23 extending into the material placing groove 2222 slide out from the material placing groove 2222. When the external force on the end of the top block 23 extending out from the second rotating surface 2221 disappears, the spring 25 will push one end of the top block 23 to remain extending into the material placing groove 2222 and the other end to remain extending out from the second rotating surface 2221.

[0047] As Figure 4 shown, in an embodiment, the replacement part 24 includes a bottom block 241, a locking platform 242 and a drill bit 243. The bottom block 241 is slidably arranged in the sliding groove 212. The locking platform 242 is arranged on the bottom block 241. The drill bit 243 is detachably arranged on the locking platform 242. A locking groove 2411 is formed on the bottom block 241, and one end of the top block 23 extending into the material placing groove 2222 is inserted into the locking groove 2411.

[0048] It should be noted that when the drive shaft of the drilling machine drives the rotating block 22 to fit with the disc block 10, one of the sliding grooves 212 on the collecting disc 21 will communicate with the material placing groove 2222 on the rotating block 22. In this way, the bottom block 241 can slide into the material placing groove 2222 from the sliding groove 212, and then drive the drill bit 243 on the bottom block 241 to slide onto the rotating block 22. Further, a locking groove 2411 is formed on the bottom block 241. When the bottom block 241 drives the drill bit 243 to completely slide into the material placing groove 2222, the locking groove 2411 communicates with the locking hole 2223, so that one end of the top block 23 extending into the material placing groove 2222 can be inserted into the locking groove 2411 from the locking hole 2223, enabling the top block 23 to lock the bottom block 241. In this way, the bottom block 241 cannot slide out after sliding into the material placing groove 2222. Further, when one end of the top block 23 extending from the second rotating surface 2221 is externally squeezed, the other end of the top block 23 slides out of the locking groove 2411, enabling the bottom block 241 to slide out of the material placing groove 2222. In this way, when the operator needs to replace the drill bit 243, the operator will operate the drive shaft of the drilling machine to move upward, causing the rotating block 22 to fit with the disc block 10. When the second rotating surface 2221 fits with the first rotating surface 131, the first rotating surface 131 will first squeeze one end of the top block 23 extending from the second rotating surface 2221, causing the top block 23 to compress the spring 25 toward the side of the circular block 13 away from the cylinder 221, and then the end extending into the material placing groove 2222 will be disengaged from the clamping connection with the bottom block 241. When the operator continuously operates the drive shaft to move upward until the step on the second rotating surface 2221 abuts against the step on the first rotating surface 131, at this time, one of the sliding grooves 212 on the collecting disc 21 will communicate with the material placing groove 2222 on the rotating block 22. The bottom block 241 located in the material placing groove 2222 can slide into the sliding groove 212 from the material placing groove 2222 because it loses the clamping connection of the top block 23. Further, the operator rotates the collecting disc 21 to make another sliding groove 212 communicate with the material placing groove 2222, enabling the bottom block 241 in the other sliding groove 212 to slide into the material placing groove 2222. After another bottom block 241 slides into the material placing groove 2222, when the operator operates the drive shaft to slide downward to drive the rotating block 22 away from the disc block 10, the first rotating surface 131 will be disengaged from the second rotating surface 2221, causing one end of the top block 23 extending from the second rotating surface 2221 to lose the external squeezing force. At this time, the spring 25 will push one end of the top block 23 to extend from the second rotating surface 2221, and at the same time, the end of the top block 23 extending into the material placing groove 2222 will continue to extend into the locking groove 2411 of another bottom block 241, enabling the bottom block 241 extending into the material placing groove 2222 to clamp another bottom block 241 so that it cannot slide out of the material placing groove 2222 into the sliding groove 212.Further, a number of sliding grooves 212 are formed in the tray 21, and a replacement part 24 is slidably disposed on each sliding groove 212. The locking platform 242 is disposed on the bottom block 241, and a screw hole is formed in the locking platform 242. The drill bit 243 can be installed on the locking platform 242 through a screw. In this way, drill bits 243 required for various drilling operations can be installed on the tray 21 to meet various drilling requirements.

[0049] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
