[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-13 The present invention provides a drilling device for mechanical processing and manufacturing, including a processing table 1, a support frame 3 is fixedly installed on the top of the processing table 1, a drilling mechanism 4 is arranged on the top of the support frame 3, the drilling mechanism 4 includes a drill sleeve 43 installed on the bottom end of the support frame 3, a drill rod 44 for mechanical drilling is installed inside the drill sleeve 43, and a spiral groove 45 is opened on the outer surface of the drill rod 44.

[0036] When drilling a mechanical part through the drill rod 44, when the drill rod 44 rotates, the spiral groove 45 can guide the debris generated by drilling to be discharged along the direction of the spiral groove 45, thereby avoiding the accumulation of debris at the drill hole. The design of the spiral groove 45 enables the debris generated by drilling to be discharged quickly, avoiding the increase in drilling resistance and increased wear of the drill rod 44 caused by the accumulation of debris, thereby improving the drilling efficiency.

[0037] In the technical solution of the embodiment of the present application, a discharge mechanism 5 is provided inside the drill rod 44, and the discharge mechanism 5 includes a fixed rod 52 rotatably installed inside the drill rod 44, a first motor 51 is fixedly installed inside the drill sleeve 43, and the output shaft of the first motor 51 is fixedly connected to the fixed rod 52, and a second bevel gear 56 is fixedly installed on the outer surface of the fixed rod 52, and a material guide cylinder 53 is connected and installed between the spiral groove 45 and the inner wall of the drill rod 44, and a spiral rod 54 for conveying debris is rotatably installed inside the material guide cylinder 53, and a first bevel gear 55 is fixedly installed at one end of the spiral rod 54, and the first bevel gear 55 is meshed with the second bevel gear 56.

[0038] Among them, when the drill rod 44 is drilling, the rotation of the spiral rod 54 can enable the debris accumulated in the spiral groove 45 to be introduced through the guide tube 53, thereby reducing the debris stuck in the spiral groove 45 and improving the efficiency of debris processing. The timely discharge of debris reduces the friction and wear on the outer surface of the drill rod 44 and extends the service life of the drill rod 44. At the same time, the reduction of debris makes the force on the drill rod 44 more uniform during the drilling process, thereby enhancing the stability of the drill rod 44.

[0042] Among them, the first motor 51 drives the connecting rod 581 to rotate, the connecting rod 581 drives the rotating plate 582 to rotate, and the rotating plate 582 drives the scraper 583 to rotate. The scraper 583 can export the debris from the through hole where the piston 585 is located, thereby reducing the debris adhering to the inside of the cavity 584 and ensuring the stable output of the debris.

[0043] In other embodiments, a crushing assembly 59 is disposed inside the drill rod 44 . The crushing assembly 59 includes a crushing roller 591 fixedly mounted on one end of the feeding auger 574 for crushing mechanical debris. The crushing roller 591 is located at the inner bottom of the drill rod 44 .

[0044] When the debris is introduced into the drill rod 44, the crushing roller 591 can continuously crush the debris in the internal space of the drill rod 44, so that some of it can be discharged in cooperation with the feeding auger 574, thereby reducing the jamming of large particles of debris inside the drill rod 44 and affecting the discharge of the material.

[0045] In other embodiments, an annular liquid storage tank 596 filled with coolant is fixedly installed inside the drill sleeve 43, a cooling groove 594 for cooling the drill rod 44 is opened inside the drill rod 44 near the crushing roller 591, a liquid inlet pipe 595 is connected between the cooling groove 594 and the annular liquid storage tank 596, a spiral blade 593 for stirring the coolant is fixedly installed at one end of the crushing roller 591 located inside the cooling groove 594, and a plurality of air holes 592 are opened inside the cooling groove 594 near the crushing roller 591.

[0046] Among them, by distributing the coolant stored inside the drill rod 44 along the liquid inlet pipe 595 inside the drill rod 44, and coordinating the stirring of the spiral blade 593, the coolant is evenly distributed and continuously circulated inside the drill rod 44, effectively improving the thermal stability of the drill rod 44, and helping to prevent the drill rod 44 from being deformed or damaged due to high temperature, thereby ensuring the safety and reliability of the drilling operation.

[0047] In other embodiments, a steel cylinder 46 for reinforcing the strength of the drill rod 44 is fixedly installed inside the drill rod 44 , and the spiral rod 54 and the feeding assembly 57 are both arranged inside the steel cylinder 46 .

[0048] Among them, by installing a steel cylinder 46 inside the drill rod 44 , the firmness of the drill rod 44 is improved, thereby improving the drill rod 44 to achieve stable output and ensure the drilling accuracy of the drill rod 44 .

[0049] In other embodiments, a first connecting pipe 597 is installed between the cooling groove 594 and the inner bottom wall of the steel cylinder 46, a second connecting pipe 598 is installed between the annular liquid storage tank 596 and the cavity 584 inside the drill sleeve 43, and a water inlet pipe 599 with a one-way valve is installed on the outer surface of the drill sleeve 43.

[0050] Among them, by providing a first connecting pipe 597 and a second connecting pipe 598, cooling water can be circulated inside the drill rod 44 along the annular liquid storage tank 596, the liquid inlet pipe 595, and the cooling groove 594, which can not only improve the cooling effect, but also when the debris is transported through the feeding auger 574, the cooling water can effectively absorb and take away the heat generated by the feeding auger 574 during long-term and high-intensity work, thereby preventing the equipment from being damaged or performance degradation due to overheating. At the same time, moisture can cause a certain viscosity between the debris particles, which not only reduces the friction and resistance between the particles, but also makes the auger smoother during the transportation process, thereby improving the transportation efficiency.

[0051] In other embodiments, magnetic plates 2 for absorbing debris are fixedly mounted on both ends of the support frame 3 , and the drill rod 44 is disposed between the magnetic plates 2 .

[0052] Among them, the magnetic plate 2 can use its magnetic force to absorb metal debris generated during the drilling process. These debris are usually small and difficult to effectively remove by conventional means, and the magnetic plate 2 can easily capture them, thereby avoiding the accumulation of debris in the drilling area, which can not only improve the efficiency of debris treatment, but also ensure the cleanliness of the drilling area and guarantee subsequent drilling operations; the accumulation of metal debris will cause damage to the drill rod 44 and drilling equipment, such as scratches, wear or blockage. The presence of the magnetic plate 2 can promptly remove these potential harmful substances, reduce their risk of damage to the drill rod 44 and equipment, and help to extend the service life of the drill rod 44 and drilling equipment and reduce maintenance costs.

[0053] In other embodiments, the outer surface of the drill rod 44 is provided with a protection mechanism 6, which includes an annular plate 61 fixedly mounted on the output end of the hydraulic rod 41, and the outer surface of the drill sleeve 43 is slidably provided with a baffle 62 for protecting against debris splashing.

[0055] In other embodiments, a slide groove 63 is provided on the outer surface of the baffle 62, a slider is fixedly installed inside the annular plate 61, the slider is slidably installed inside the slide groove 63, the baffle 62 is composed of multiple arc-shaped plates to form a cylinder 510 shape, and the drill rod 44 is located inside the baffle 62.

[0056] Among them, by providing a plurality of baffles 62 with adjustable heights, the baffles 62 can adapt to the protection areas of different mechanical parts, ensuring that the drill rod 44 can fully fit inside the cylinder 510 formed by the baffles 62.

[0058] Among them, when drilling is required, first, by controlling the extension and retraction of the hydraulic rod 41, the drive motor 42 and the drill sleeve 43 together with the drill rod 44 are lowered to the top of the mechanical part to be drilled, and then the drive motor 42 is started to rotate its output shaft, thereby driving the drill sleeve 43 and the drill rod 44 to rotate. While the drill rod 44 is rotating, downward pressure is applied through the hydraulic rod 41 to drill the required hole on the mechanical part. The combination of the hydraulic rod 41 and the drive motor 42 is adopted, and the device can realize fast and stable lifting and rotating actions, thereby efficiently completing the drilling operation.

[0059] Working principle: The drill rod 44 is driven to rotate by the driving motor 42, so as to realize drilling of mechanical parts. When drilling, by starting the first motor 51, the first motor 51 drives the fixed rod 52 to rotate, the fixed rod 52 drives the second bevel gear 56 to rotate, the second bevel gear 56 drives the first bevel gear 55 to rotate, and the first bevel gear 55 drives the spiral rod 54 to rotate. Through the rotation of the spiral rod 54, the debris accumulated in the spiral groove 45 can be introduced through the guide barrel 53. At the same time, the fixed rod 52 drives the second circular gear 572 to rotate, the second circular gear 572 drives the first circular gear 571 to rotate, and the first circular gear 571 drives the feeding auger 574 to rotate. The feeding auger 574 cooperates with the feeding barrel 573 to discharge the debris introduced into the drill rod 44, effectively reducing the interference of the debris on the drilling process, thereby significantly improving the drilling accuracy.
