[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4A drilling device for machining engine cylinder heads includes a base plate 1. A clamping assembly is provided on the top side of the base plate 1. Two cylinders 2 are fixedly installed on the bottom side of the base plate 1. The output ends of the two cylinders 2 pass through the base plate 1 and are fixedly connected to the same top plate 3. A fan 7 and a collection box 8 are fixedly installed on the top side of the top plate 3. A connecting pipe 9 is fixedly installed on one side of the fan 7, and the other end of the connecting pipe 9 is fixedly connected to one side of the collection box 8 and communicates with the collection box 8. A filter plate 12 is provided inside the collection box 8, and a cleaning assembly is provided on one side of the filter plate 12. A drilling mechanism is provided on the top side of the top plate 3. A linkage assembly is provided between the drilling mechanism and the cleaning assembly. By providing the fan 7, the fan 7 is turned on simultaneously during the drilling process of the drill bit 5. The operation of the fan 7 drives the suction nozzle 11 to suck up the debris and dust generated during drilling. Dust and debris are drawn into the collection box 8 through the extraction pipe 10 for storage and subsequent unified processing. The collection box 8 is equipped with a filter plate 12, which can effectively block dust and debris, preventing debris from entering the blower 7 and causing damage to the blower 7. After the blower 7 is turned on, it can quickly form a negative pressure in the drilling area, allowing debris and dust to be sucked away quickly, greatly reducing the situation of debris flying around. At the same time, with the help of the first pulley 6, when the motor 4 is running, the brush 17 can automatically move back and forth to clean the filter plate 12, which further improves the overall cleaning effect. The stable cleaning effect not only ensures that the environment around the equipment is in a low dust state for a long time, but also reduces the probability of equipment failure caused by dust accumulation. At the same time, it makes the entire drilling operation process smoother and reduces the time loss caused by the interruption of cleaning work.

[0023] Specifically, the clamping assembly includes two fixed plates 24 fixedly installed on the top side of the top plate 3. Electric push rods 25 are fixedly installed on the opposite sides of the two fixed plates 24. The output ends of the two electric push rods 25 pass through the fixed plates 24 and are fixedly connected to clamping plates 26. By setting two clamping plates 26, when drilling the cylinder head, the cylinder head to be drilled is first placed between the two clamping plates 26. Then, the two electric push rods 25 are started simultaneously, and the two clamping plates 26 will firmly clamp the cylinder head. The stable clamping of the clamping plates 26 greatly avoids displacement or shaking of the cylinder head during drilling, providing a solid and reliable foundation for subsequent drilling operations and ensuring the accuracy and safety of the drilling operation.

[0024] Specifically, the drilling mechanism includes a motor 4 fixedly installed on the top side of the top plate 3. The output end of the motor 4 rotates through the top plate 3 and is fixedly connected to a drill bit 5. The drill bit 5 faces the bottom plate 1. A first pulley 6 is fixedly sleeved on the outside of the output end of the motor 4. With the drill bit 5 installed, after clamping is completed, two cylinders 2 are started simultaneously. The operation of the cylinders 2 drives the top plate 3 to move downward. When the top plate 3 moves downward and the drill bit 5 contacts the cylinder head, the motor 4 is started. The operation of the motor 4 drives the drill bit 5 to rotate, thereby realizing the drilling operation on the cylinder head. At the same time as the motor 4 is running, the fan 7 is started to simultaneously absorb the dust generated during drilling.

[0025] Specifically, the cleaning component includes a collection box 8 with a circular hole on one side, a lead screw 13 installed inside the hole, one end of the lead screw 13 being rotatably connected to the inner wall of one side of the collection box 8, and the other end of the lead screw 13 being fixedly connected to a first bevel gear 14. A guide rod 15 is fixedly installed inside the collection box 8, and the same slider 16 is slidably sleeved on the outer side of the guide rod 15 and the lead screw 13. A brush 17 is fixedly installed on the other side of the slider 16, and the other end of the brush 17 is attached to one side of the filter plate 12. The linkage component... A fixing bracket 18 is fixedly installed on one side of the top plate 3. The fixing bracket 18 is U-shaped, and round holes are opened on both sides of the fixing bracket 18. The same linkage rod 19 is installed in the two round holes. Two limiting rings 23 are fixedly sleeved on the outer side of the linkage rod 19. The two limiting rings 23, which are far apart from each other, are respectively attached to the inner walls of the two sides of the fixing bracket 18. A second bevel gear 22 is fixedly connected to the top of the linkage rod 19. The second bevel gear 22 meshes with the first bevel gear 14. The bottom end of the linkage rod 19 is fixed... A second pulley 20 is fixedly connected to the first pulley 6. The second pulley 20 and the first pulley 6 share the same belt 21. With the first pulley 6 and the second pulley 20 connected by the same belt 21, the second pulley 20 will synchronously drive the linkage rod 19 to rotate under the transmission action of the belt 21. Since the top of the linkage rod 19 is fixedly connected to the second bevel gear 22, which meshes with the first bevel gear 14, the first bevel gear 14 will synchronously drive the lead screw 13 to rotate under the transmission of the second bevel gear 22. In turn, the slider 16 slidably connected to the outside of the lead screw 13 drives the brush 17 to move back and forth, cleaning the dust and debris attached to the filter plate 12. The stable cleaning by the brush 17 ensures that the filter plate 12 is in good working condition for a long time. Cleaning the filter plate 12 can keep the suction of the fan 7 at the best state, thereby more effectively adsorbing the dust and debris generated by drilling.

[0026] Specifically, an extraction pipe 10 is fixedly installed on one side of the collection box 8, and the extraction pipe 10 is connected to the collection box 8. The other end of the extraction pipe 10 passes through the top plate 3 and is fixedly connected to a suction nozzle 11. The suction nozzle 11 faces the drill bit 5. With the suction nozzle 11, when the fan 7 is running, it will drive the suction nozzle 11 to suck up the dust and debris generated by the drilling. Then the dust and debris will enter the collection box 8 through the extraction pipe 10 for storage, which is convenient for subsequent unified treatment. Because the suction nozzle 11 faces the drill bit 5, it ensures that the dust and debris generated by the drilling are collected efficiently. This not only maintains the cleanliness of the working environment, but also reduces the potential impact of dust on the health of operators.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0028] In use: By placing the cylinder head to be drilled between two clamping plates 26, and then simultaneously starting two electric push rods 25, the two clamping plates 26 can clamp the cylinder head. After clamping, simultaneously starting two cylinders 2 will drive the top plate 3 to move down. When the top plate 3 moves down and the drill bit 5 comes into contact with the cylinder head, the motor 4 will start running. The running of the motor 4 will drive the drill bit 5 to rotate, thereby realizing the drilling of the cylinder head. During the drilling process, the blower 7 will start running simultaneously. The running of the blower 7 will drive the suction nozzle 11 to suck up the debris and dust generated during drilling. Then, the debris and dust will be extracted through the extraction pipe 10 into the collection box 8 for storage, which will facilitate subsequent unified processing. Because the collection box 8 is equipped with a filter plate 12, the filter plate 12 can block dust and debris, thereby preventing debris from entering the blower 7 and causing damage to the blower 7. And because the output end of the motor 4 is fixed with a sleeve on the outside... A first pulley 6 is connected, and the first pulley 6 and the second pulley 20 share the same belt 21. Therefore, under the transmission of the belt 21, the second pulley 20 will synchronously drive the linkage rod 19 to rotate. Since the top of the linkage rod 19 is fixedly connected to the second bevel gear 22, and the second bevel gear 22 meshes with the first bevel gear 14, under the transmission of the second bevel gear 22, the first bevel gear 14 will synchronously drive the lead screw 13 to rotate. This will cause the slider 16, which is slidably sleeved on the outside of the lead screw 13, to drive the brush 17 to reciprocate and clean the dust and debris attached to the filter plate 12. By cleaning the filter plate 12, the suction power of the fan 7 can always be kept at the optimal state, so as to better adsorb the dust and debris generated by drilling. Through the transmission of the first pulley 6, when the motor 4 is running, the brush 17 can reciprocate and clean the filter plate 12, further improving the overall cleaning effect.
