When the second hydraulic rod moves to the left, it will drive the components to act in the reverse direction, causing the fourth hydraulic rod to descend and the telescopic plate to descend at the same time, and the position of the collection device can be flexibly adjusted according to needs to better adapt to the debris collection requirements in different situations, improving the automation degree of the equipment and the cleanliness of the working environment.

[0021] 3. In this application, when the collection box rises or falls, through the linkage of components such as the vertical plate, the second rotating rod, the second circular gear, and the second rack, the knocking block knocks on the collection box. This design can improve the effect of dumping debris from the collection box. By knocking, the debris attached to the inner wall of the collection box or piled up is loosened and discharged smoothly, avoiding debris blockage or residue, improving the efficiency and thoroughness of debris cleaning, facilitating the subsequent cleaning of the collection box and the centralized treatment of debris, and at the same time preparing for the next drilling process, ensuring the continuous and stable operation of the equipment.

[0039] Embodiment 1, see Figures 1-8 , this embodiment provides a drilling device for small holes in an engine connecting rod, including:

[0040] A base 1, on the top of the base 1 is assembled a drilling machine body 6;

[0041] The clamping assembly 5 is used to clamp the engine connecting rod, and the clamping assembly 5 is assembled on the top of the base 1;

[0042] A fixing base 21 is assembled on the top of the base 1. A fixing plate 22 is assembled on the top of the fixing base 21. A connecting block 23 is assembled on the top of the fixing plate 22. A chute 25 is formed on the outer wall of the connecting block 23. A slider 27 is slidably connected to the inner wall of the chute 25. A moving block 26 is assembled on the top of the slider 27. A transmission component for transmission is assembled between the moving block 26 and the connecting block 23. A motor 29 is assembled on the side of the moving block 26. An operating platform 210 is assembled on the top of the moving block 26. A suction cup 222 is arranged on the side of the operating platform 210. A hydraulic component for generating suction force for the suction cup 222 is assembled on the top of the fixing plate 22. The base 1 serves as a basic support component, and a drilling machine body 6 is assembled on the top for drilling operations. The clamping component 5 clamps and fixes the engine connecting rod to ensure stability during the drilling process. Structures such as the fixing base 21, the fixing plate 22, the connecting block 23, the chute 25, and the slider 27 cooperate with each other to realize the movement of the moving block 26, and then drive the suction cup 222 on the operating platform 210 to move to a suitable position. The hydraulic component provides suction force for the suction cup 222 to ensure that the engine connecting rod can be firmly adsorbed on the operating platform 210 during drilling, improving the drilling accuracy and safety, and realizing the drilling function for the small holes of the engine connecting rod. The connecting rod is fixed by the clamping component 5, and at the same time, the hydraulic component is used to generate suction force for the suction cup 222, which is convenient for adsorbing and fixing the workpiece. The transmission component includes a worm gear 24, and the worm gear 24 is fixedly connected to the outer wall of the connecting block 23. A worm 28 is rotatably connected to the inner side of the wall of the moving block 26 through a bearing. The worm 28 extends to the right through the moving block 26, and its extended end is fixedly connected to the output end of the motor 29. The worm gear 24 and the worm 28 are meshed with each other. The output end of the motor 29 drives the worm 28 to rotate. The worm 28 is meshed with the worm gear 24, and the worm gear 24 is fixedly connected to the outer wall of the connecting block 23, so that the moving block 26 moves in the chute 25. Due to the self-locking property of the worm gear 24 and worm 28 transmission, when the motor 29 stops rotating, the moving block 26 can remain stable at the current position and will not be displaced due to external forces, ensuring the accuracy and reliability of the drilling operation. Through the worm gear 24 and worm 28 transmission, the stable and precise movement of the moving block 26 is realized, and it has self-locking property, which can ensure the stable position of the moving block 26 during the drilling process. The hydraulic component includes a first hydraulic chamber 212, and the first hydraulic chamber 212 is fixedly connected to the top of the fixing plate 22. A first hydraulic rod 213 is slidably connected to a piston at one end inside the first hydraulic chamber 212. A resilient telescopic rod 214 is fixedly connected to the top of the first hydraulic rod 213. A fixing rod 216 is fixedly connected to the front of the moving block 26. A first spring 215 is movably sleeved on the outer walls of the first hydraulic rod 213 and the resilient telescopic rod 214. The first hydraulic rod 213 in the first hydraulic chamber 212 is hydraulically driven to convert hydraulic energy into mechanical energy, driving the resilient telescopic rod 214 and the first spring 215 to perform telescopic movements.When it is necessary to adsorb the engine connecting rod, the first hydraulic rod 213 extends, and the elastic telescopic rod 214 elongates accordingly. The first spring 215 is stretched, generating elastic potential energy. At the same time, the suction cup 222 generates suction to adsorb the workpiece. After the drilling is completed, the first hydraulic rod 213 retracts. Under the elastic action of the elastic telescopic rod 214 and the first spring 215, the suction cup 222 can quickly reset and release the workpiece, facilitating subsequent operations. The hydraulic component can provide stable suction for the suction cup 222. At the same time, through the cooperation of the elastic telescopic rod 214 and the first spring 215, it plays a buffering and resetting role in the movement of the first hydraulic rod 213, improving the stability and reliability of the overall device. A second hydraulic chamber 218 is fixedly connected to the top of the operation platform 210. One end of the piston inside the second hydraulic chamber 218 is slidably connected to a second hydraulic rod 219. A sealing gasket 220 is fixedly connected to the side of the second hydraulic rod 219. A sleeve 221 is fixedly connected to the side of the operation platform 210. The sealing gasket 220 is slidably connected to the inner wall of the sleeve 221. The second hydraulic rod 219 slides with the piston inside the second hydraulic chamber 218, driving the sealing gasket 220 to slide on the inner wall of the sleeve 221 through hydraulic transmission. The sleeve 221 is fixed to the side of the operation platform 210, providing a stable sliding track for the sealing gasket 220, preventing the sealing gasket 220 from shifting or shaking during movement, thereby ensuring the sealing performance and stability of the hydraulic system and ensuring the normal operation of the entire device. The cooperation between the second hydraulic chamber 218 and the sealing gasket 220 can achieve the sealing and support of the operation platform 210, ensuring the stable operation of the hydraulic system. At the same time, the sleeve 221 plays a guiding and limiting role for the sealing gasket 220, ensuring that the suction cup 222 generates suction on the engine connecting rod. The first hydraulic chamber 212 and the second hydraulic chamber 218 are connected and set through a connecting hose 217. A through hole 211 is opened at the top of the operation platform 210. The elastic coefficient of the elastic telescopic rod 214 is relatively large. The first hydraulic chamber 212 and the second hydraulic chamber 218 are connected through the connecting hose 217, enabling hydraulic oil to flow between the two hydraulic chambers and realizing the synchronous control of the hydraulic system. When the first hydraulic rod 213 moves, the hydraulic oil enters the second hydraulic chamber 218 through the connecting hose 217, pushing the second hydraulic rod 219 to move, thereby realizing the adsorption and release actions of the suction cup 222. The through hole 211 at the top of the operation platform 210 ensures that the debris generated during processing will not accumulate on the top of the operation platform 210. By connecting the first hydraulic chamber 212 and the second hydraulic chamber 218 through the connecting hose 217, the collaborative work of the hydraulic system is realized.

[0043] When the above-mentioned device is in specific use, the engine connecting rod is placed on the top of the operation platform 210, and the engine connecting rod is clamped by the clamping assembly 5, so that the engine connecting rod is attached to the right side of the operation platform 210. Then, the motor 29 is started, and the motor 29 drives the worm 28 to rotate. The worm 28 rotates and slides on the outer wall of the worm gear 24, so that the worm 28 slides on the moving block 26 and slides to the left through the slider 27. The moving block 26 drives the fixed rod 216 to squeeze the elastic telescopic rod 214, and the elastic telescopic rod 214 squeezes the first hydraulic rod 213. During the process of the first hydraulic rod 213 descending, the internal pressures of the first hydraulic chamber 212, the connecting hose 217, and the second hydraulic chamber 218 increase, driving the second hydraulic rod 219 to move to the right. When the second hydraulic rod 219 moves to the right, it drives the sealing gasket 220 to move to the right. During the movement of the sealing gasket 220, a negative pressure is formed inside the sleeve 221, causing the suction cup 222 to generate suction, thereby improving the stability of the engine connecting rod during the movement of the operation platform 210. When the moving block 26 continues to move to the left, since the first hydraulic rod 213 has descended to the limit position, the moving block 26 and the fixed rod 216 will compress the elastic telescopic rod 214.

[0044] Embodiment 2, see Figures 1-8, on the basis of the first embodiment, a collection device 3 for collecting the debris generated by drilling is assembled on the top of the base 1. Each component in the collection device 3 cooperates with each other to collect and process the debris generated by drilling. For example, the first rack 32 at the bottom of the second hydraulic rod 219 meshes with the first circular gear 35. When the second hydraulic rod 219 moves, it drives the first circular gear 35 to rotate, thereby driving the extrusion block 36 to extrude and collect the debris. Or through the synergistic action of other components, the debris is collected into the collection box 311, avoiding the debris from splashing or accumulating on the workbench and affecting the normal progress of the drilling operation. The collection device 3 can effectively collect the debris generated during the drilling process, keep the working environment clean, and improve production efficiency and safety. The collection device 3 includes a connecting rod 31. The connecting rod 31 is fixedly sleeved on the outer wall of the second hydraulic rod 219. The bottom of the second hydraulic rod 219 is fixedly connected with a first rack 32. A connecting plate 33 is assembled on the side of the operation platform 210. The front of the connecting plate 33 is rotatably connected with a first rotating rod 34 through a bearing. The first circular gear 35 is fixedly sleeved on the outer wall of the first rotating rod 34. The extrusion block 36 is fixedly sleeved on the outer wall of the first rotating rod 34. A third hydraulic chamber 37 is assembled on the side of the operation platform 210. One end of the piston in the third hydraulic chamber 37 is slidably connected with a third hydraulic rod 38. The second spring 39 is movably sleeved on the outer wall of the third hydraulic rod 38. One end of the piston on the inner wall of the third hydraulic chamber 37 is slidably connected with a fourth hydraulic rod 310. The fourth hydraulic rod 310 is hinged to the side of the collection box 311. The collection box 311 is hinged to the bottom of the operation platform 210 through a hinge rod. The third hydraulic rod 38 is hinged to the side of the collection box 311. The bottom of the operation platform 210 is fixedly connected with a telescopic plate 312. The telescopic plate 312 is hinged to the side of the collection box 311. The first rack 32 meshes with the first circular gear 35. When it is necessary to clean the debris in the collection box 311, the third hydraulic rod 38 extends or retracts. Under the elastic action of the second spring 39, it drives the collection box 311 to rotate around the hinge rod, opening or closing the collection box 311. The telescopic plate 312 plays a guiding and limiting role during the opening and closing process of the collection box 311, ensuring the smooth movement and reliable fixation of the collection box 311. At the same time, the meshing relationship between the first rack 32 and the first circular gear 35 enables other related components to perform corresponding actions synchronously during the opening and closing process of the collection box 311, such as the movement of the extrusion block 36, further improving the collection efficiency and effect. The collection box 311 is connected to the bottom of the operation platform 210 through a hinge rod, and the cooperation of the third hydraulic rod 38 and the telescopic plate 312 is used to realize the opening and closing and fixation of the collection box 311, facilitating the cleaning and replacement of the debris in the collection box 311.

[0045] When the above device is in specific use, when the second hydraulic rod 219 moves to the right, it drives the connecting rod 31 to move to the right. The connecting rod 31 drives the first rack 32 to move to the right. The first rack 32 drives the first circular gear 35 to rotate. The first circular gear 35 drives the first rotating rod 34 to rotate. The first rotating rod 34 drives the extrusion block 36 to rotate. When the extrusion block 36 no longer extrudes the third hydraulic rod 38, the second spring 39 drives the third hydraulic rod 38 to move to the right. During the process of the third hydraulic rod 38 moving to the right, the internal pressure of the third hydraulic chamber 37 decreases, driving the fourth hydraulic rod 310 to rise, which is used to catch the debris falling from the through hole 211 during processing. When the second hydraulic rod 219 moves to the left, it drives the connecting rod 31 to move to the left. The connecting rod 31 drives the first rack 32 and the first circular gear 35 to rotate. The first circular gear 35 drives the first rotating rod 34 to rotate. The first rotating rod 34 drives the extrusion block 36 to extrude the third hydraulic rod 38. The internal pressure of the third hydraulic chamber 37 increases, driving the fourth hydraulic rod 310 to descend, and at the same time, the telescopic plate 312 descends.

[0046] Embodiment 3, refer to Figures 1-8 , on the basis of Embodiment 1, a knocking device 4 for further making the debris inside the collection box 311 fall is assembled on the top of the base 1. The knocking device 4 includes a second rack 41. The second rack 41 is fixedly connected to the bottom of the operation platform 210. A vertical plate 42 is fixedly connected to the bottom of the inner wall of the collection box 311. A second rotating rod 43 is rotatably connected to the side of the vertical plate 42 through a bearing. A second circular gear 44 is fixedly connected to the outer wall of the second rotating rod 43. A knocking block 45 is fixedly sleeved on the outer wall of the second rotating rod 43. The second rack 41 and the second circular gear 44 are meshed with each other. The second rotating rod 43 rotatably connected to the side of the vertical plate 42 drives the knocking block 45 to regularly knock on the inner wall of the collection box 311 under the meshing relationship between the second circular gear 44 and the second rack 41. When the second rack 41 moves, the second circular gear 44 rotates accordingly, and the knocking block 45 generates a knocking force on the inner wall of the collection box 311, prompting the debris to loosen and fall. This knocking method can more accurately knock on the debris at different positions inside the collection box 311, improving the comprehensiveness and thoroughness of debris collection. By combining with the knocking device 4, the knocking effect on the debris inside the collection box 311 is further optimized, making it fall more smoothly and improving the efficiency and quality of debris collection.

[0047] When the above-mentioned device is in specific use, when the collection box 311 rises, it drives the vertical plate 42 to rise. The vertical plate 42 drives the second rotating rod 43 and the second circular gear 44 to rise. When the second circular gear 44 moves upward, through the meshing of the second circular gear 44 and the second rack 41, the second circular gear 44 rotates. The second circular gear 44 drives the second rotating rod 43 to rotate, and the second rotating rod 43 drives the knocking block 45 to knock on the collection box 311. When the collection box 311 descends, the vertical plate 42 drives the second rotating rod 43 and the second circular gear 44 to descend. When the second circular gear 44 moves downward, through the meshing of the second circular gear 44 and the second rack 41, the second circular gear 44 rotates. The second circular gear 44 drives the second rotating rod 43 to rotate, and the second rotating rod 43 drives the knocking block 45 to knock on the collection box 311, improving the effect of the collection box 311 pouring out debris.

[0048] When the above-mentioned device is in specific use, as described above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
