[0002] A drilling machine is a mechanical device that uses rotation, impact, or vibration to precisely drill holes in various materials. It is widely used in construction, manufacturing, maintenance, and other fields.

[0003] However, the tooling for hole-type parts on traditional drilling machines is often fixed, which makes it impossible to quickly replace the tooling to adapt to parts of different sizes and shapes, reducing the overall applicability and processing efficiency of the equipment. Secondly, the drilling machine body on traditional drilling machines cannot be quickly adjusted to perform drilling operations on different parts to be processed, making it difficult to meet the diverse processing needs of parts. Utility Model Content

[0004] The purpose of this invention is to provide a drilling machine that can quickly replace tooling for hole-type parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: it includes a workbench, a processing table switching component is provided on the workbench, and a drilling component is provided on the top of the workbench.

[0006] As a preferred embodiment of this utility model, the processing table switching assembly includes a mounting groove formed on the worktable. A fixing sleeve is provided on one side of the mounting groove, and a lead screw is inserted into the fixing sleeve. A motor is provided on the side of the mounting groove away from the fixing sleeve. The transmission end of the motor is connected to one end of the lead screw. A drive block 1 and a drive block 2 are spirally sleeved on the outside of the lead screw. A pair of guide rails symmetrically arranged in the mounting groove are provided. The drive blocks 1 and 2 are slidably mounted on the guide rails. A cover plate is provided on the mounting grooves on both sides of the drive blocks 1 and 2.

[0007] As a preferred embodiment of the present invention, the drive block is provided with a tooling table, and a pair of telescopic cylinders are symmetrically arranged on the tooling table. The top of the telescopic rod of each of the two telescopic cylinders is provided with an anti-slip clamping seat. A pair of guide posts are provided on one side of each anti-slip clamping seat. Guide sleeves are provided on the tooling table on both sides of the telescopic cylinder at the positions corresponding to the guide posts.

[0008] As a preferred embodiment of this utility model, the driving block 2 is provided with a tooling table 2, and the tooling table 2 is provided with fixing blocks on all four sides. Each fixing block is provided with a pair of oil storage cylinders on one side. Each oil storage cylinder is slidably provided with a piston 1. Each piston 1 is provided with a piston rod, which passes through the oil storage cylinder. A buffer spring is provided between the piston rod and the oil storage cylinder on the same side. An anti-slip clamping seat 2 is provided on one side of the two piston rods.

[0009] As a preferred embodiment of this utility model, the drilling assembly includes a mounting box disposed on a workbench, a second motor disposed inside the mounting box, a gear disposed on the transmission end of the second motor, a rack meshing with one side of the gear, a second guide rail disposed inside the mounting box, and the rack slidably disposed on the second guide rail.

[0010] As a preferred embodiment of this utility model, a driving block three is provided at the bottom of the rack, a cover plate two is provided on the mounting box on one side of the driving block three, a pair of telescopic cylinders two are symmetrically provided at the bottom of the driving block three, a driving block four is provided at the top of the telescopic rods of the two telescopic cylinders two, a guide rail three is provided on the driving block three, and the driving block four is slidably provided on the guide rail three.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This invention utilizes a processing table switching assembly. The combination of motor one and lead screw converts the rotational motion of the lead screw into the linear motion of drive block one and drive block two. Drive block one and drive block two respectively support tooling table one and tooling table two, moving linearly under the guidance of guide rail one, thus enabling rapid tooling replacement for hole-type parts. Secondly, tooling table one drives the anti-slip clamping seat one to move via telescopic cylinder one, achieving clamping and releasing of the workpiece. Guide post one and guide sleeve one provide guidance for the movement of anti-slip clamping seat one, ensuring clamping accuracy. Furthermore, tooling table two uses a combination of a fixed block, oil reservoir, piston one, piston rod, and anti-slip clamping seat two to clamp irregular parts. The oil reservoir stores hydraulic oil, and piston one slides within the oil reservoir under the drive of the piston rod. Combined with a buffer spring, anti-slip clamping seat two can automatically adjust its position according to the shape of the irregular part, achieving stable clamping. The hydraulic oil generates damping force during the movement of piston one, ensuring the stability of anti-slip clamping seat two.

[0013] This invention features a drilling assembly. Motor 2 drives a gear to rotate, transmitting power to a rack. Guided by guide rail 2, the rack moves linearly, adjusting the horizontal position of the drilling machine body. Next, telescopic cylinder 2 drives drive block 4 to move along guide rail 3, adjusting the horizontal position of the drilling machine body. This allows the drilling machine body to quickly and sequentially align with multiple workpiece positions. Furthermore, telescopic cylinder 3, through the telescopic movement of the telescopic rod, drives guide post 2 and the drilling machine body to rise and fall along guide sleeve 2, ensuring the accuracy of drilling and the controllability of the drilling depth.

[0017] like Figures 1-7 As shown, the present invention proposes a drilling machine with a quick-change tooling for hole-type parts, which includes a worktable 1, a processing table switching component 2 on the worktable 1, and a drilling component 3 on the top of the worktable 1.

[0018] The machining table switching assembly 2 includes a mounting slot 21 formed on the worktable 1. The mounting slot 21 provides a mounting base for other components in the machining table switching assembly 2. A fixing sleeve 22 is provided on one side of the mounting slot 21, and a lead screw 23 is inserted into the fixing sleeve 22. The fixing sleeve 22 provides stable support for the lead screw 23, ensuring the stability of the lead screw 23 during rotation. A motor 24 is provided on the side of the mounting slot 21 away from the fixing sleeve 22. The transmission end of the motor 24 is connected to one end of the lead screw 23. The motor 24 provides rotational power to the lead screw 23, converting the rotational power of the lead screw 23 into linear motion of the drive block 25 and the drive block 26, thereby driving... Drive block 1 25 and drive block 26 move along guide rail 1 27 to switch the positions of tooling table 1 29 and tooling table 214. Drive block 1 25 and drive block 26 are spirally sleeved on the outside of the lead screw 23. Drive block 1 25 and drive block 26 provide the installation base for tooling table 1 29 and tooling table 214 respectively. A pair of guide rails 1 27 are symmetrically arranged in the mounting groove 21. Drive block 1 25 and drive block 26 are slidably mounted on guide rails 1 27. Cover plate 1 28 is provided on the mounting groove 21 on both sides of drive block 1 25 and drive block 26. Guide rail 1 27 provides guidance for the movement of drive block 1 25 and drive block 26 to ensure their stability during the movement process.

[0019] A tooling table 29 is provided on the drive block 25. The tooling table 29 is used to place regularly shaped parts. A pair of telescopic cylinders 210 are symmetrically arranged on the tooling table 29. The top of the telescopic rod of each telescopic cylinder 210 is provided with an anti-slip clamping seat 211. The telescopic cylinder 210 drives the anti-slip clamping seats 211 on both sides to move through the telescopic movement of the telescopic rod, thereby realizing the clamping and release of the parts to be processed. A pair of guide posts 212 are provided on one side of each anti-slip clamping seat 211. Guide sleeves 213 are provided on the tooling table 29 on both sides of the telescopic cylinder 210 at the positions corresponding to the guide posts 212.

The oil reservoir 216 stores hydraulic oil and provides space for the movement of the piston 217. The anti-slip clamping seat 219 pushes the piston rod 218 and the piston 217. 7. When moving within the oil reservoir 216, piston 1 217 divides the space within the oil reservoir 216 into two chambers, facilitating the flow of hydraulic oil and the generation of damping force, ensuring the stability of anti-slip clamping seat 219. A buffer spring 220 is provided between the piston rod 218 on the same side and the oil reservoir 216. An anti-slip clamping seat 219 is provided on one side of the two piston rods 218.

After the part is processed, the buffer spring 220 can also help the anti-slip clamping seat 219 return to its original position.

[0021] The drilling assembly 3 includes a mounting box 31 mounted on the workbench 1. The mounting box 31 provides a mounting base for other components in the drilling assembly 3. A second motor 32 is installed inside the mounting box 31. A gear 33 is installed at the transmission end of the second motor 32. A rack 34 is meshed on one side of the gear 33. The second motor 32 provides power for the rotation of the gear 33. The gear 33 transmits power to the rack 34 through meshing, converting the rotational motion of the gear 33 into the linear motion of the rack 34, thereby adjusting the horizontal position of the drilling machine body 314. A second guide rail 35 is installed inside the mounting box 31. The rack 34 is slidably mounted on the second guide rail 35. The second guide rail 35 provides guidance for the movement of the rack 34, ensuring the stability of the rack 34 during movement.

[0022] A drive block 37 is provided at the bottom of the rack 34. A cover plate 36 is provided on the mounting box 31 on one side of the drive block 37. The drive block 37 provides a mounting base for the telescopic cylinder 38. A pair of telescopic cylinders 38 are symmetrically arranged at the bottom of the drive block 37. A drive block 39 is provided at the top of the telescopic rods of the two telescopic cylinders 38. A guide rail 310 is provided on the drive block 37. The drive block 39 is slidably arranged on the guide rail 310. By extending and retracting the telescopic rods of the telescopic cylinders 38, the drive block 39 is driven to move along the guide rail 310, thereby adjusting the position of the drilling machine body 314 in the horizontal axis.

[0023] The bottom of the drive block 4 39 is provided with a guide sleeve 2 311, and the guide sleeve 2 311 is provided with a telescopic cylinder 3 312. The telescopic cylinder 3 312 drives the guide post 2 313 and the drilling machine body 314 to rise and fall along the guide sleeve 2 311 through the telescopic movement of the telescopic rod. The bottom of the telescopic rod of the telescopic cylinder 3 312 is provided with a guide post 2 313 corresponding to the guide sleeve 2 311. The combination of the guide post 2 313 and the guide sleeve 2 311 provides guidance for the rising and falling of the drilling machine body 314, ensuring the stability of the drilling machine body 314 during the rising and falling process. The bottom of the guide post 2 313 is provided with the drilling machine body 314, which performs drilling processing on the parts.

[0024] Working principle: The operator first places the part to be drilled on the tooling table 29. Then, the telescopic rod of the telescopic cylinder 210 extends, driving the anti-slip clamping seat 211 to move. This allows the anti-slip clamping seats 211 on both sides to move closer together and clamp the part, ensuring stability during the part processing. Next, the drilling assembly 3 is started, and the motor 32 drives the gear 33 to rotate. The gear 33 transmits power to the rack 34 through meshing, thereby driving the rack 34 and the drive block 37 to move along the guide rail 35. Then, in conjunction with the telescopic movement of the telescopic cylinder 38, the drive block 39 moves along the guide rail 310, thereby quickly adjusting the position of the drilling machine body 314 so as to align with the parts to be processed in sequence. After each alignment, the telescopic cylinder 312 can extend to drive the guide post 313 and the drilling machine body 314 to descend along the guide sleeve 311 to contact the parts, and start the drilling machine body 314 to perform drilling operations. After drilling is completed, the telescopic cylinder 312 can retract to allow the drilling machine body 314 to rise and reset. After drilling is completed at all the positions to be processed, the telescopic cylinder 210 can retract to release the parts from the anti-slip clamping seats 211 on both sides, and the operator can then remove the parts.

[0025] If the part is irregularly shaped, the operator can drive the lead screw 23 to rotate via motor 24, converting the rotational motion of the lead screw 23 into the linear motion of drive block 25 and drive block 26. This causes drive block 25 and drive block 26 to move tooling table 29 and tooling table 214 respectively, thus moving tooling table 214 directly below the drilling assembly 3. The irregularly shaped part is then placed between several anti-slip clamps 219. When placed, the part pushes the anti-slip clamps 219 to move, and the buffer spring 220 extends and retracts to allow the anti-slip clamps 219 to conform to the surface of the part. At the same time, the anti-slip clamps 219 push the piston 217 and piston rod 218 in the oil reservoir. The piston 217 slides inside the cylinder 216, dividing the space inside the oil reservoir 216 into two chambers. The hydraulic oil in the oil reservoir 216 will repeatedly flow from one chamber to another through different small holes on the piston 217. During the flow of hydraulic oil, the friction between the hole wall and the hydraulic oil and the internal friction between the hydraulic oil molecules will hinder the flow of hydraulic oil and generate damping force, thereby ensuring the stability of the anti-slip clamping seat 219 and preventing the buffer spring 220 from rebounding too quickly, causing the anti-slip clamping seat 219 to become unstable, which in turn affects the stability and accuracy of the part processing. Then, the drilling assembly 3 is started according to the same steps as above to perform drilling operations on the part to be processed in sequence.
