[0002] According to the patent document with publication number CN219052968U, after the railing is placed inside the U-shaped cover, a small electric telescopic rod is used to drive the push plate to move downward and to one side of the railing. Then, the telescopic end of the hydraulic telescopic rod drives the push plate to move to the inside of the U-shaped cover, thereby fixing the railing inside the U-shaped cover. Subsequently, the output shaft of the second motor rotates to drive the bidirectional screw to rotate, thereby moving the two clamping plates closer together to clamp the railing.
[0003] The patent document states that, due to the limitations of the overall structure, only one railing can be drilled at a time when drilling holes in the railings. Drilling holes in each railing sequentially may cause misalignment of holes in adjacent railings during later installation. Utility Model Content

Furthermore, the electrical components mentioned in this document are all electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.
[0027] The present invention will be further described below with reference to the accompanying drawings:
[0028] like Figures 1-7 As shown, a radial drilling machine for processing ship railings includes a support mechanism 2, a drilling mechanism 1 on the upper side of the support mechanism 2, and a clamping mechanism 3 located between the drilling mechanism 1 and the support mechanism 2.
[0029] In this embodiment: the support mechanism 2 includes a base 22, a side plate 21 is fixed on the top of the base 22, and two guide rails 23 are fixed on one side of the side plate 21. The base 22 is used to support the side plate 21, and one end of the stacked railings is pressed against the side of the side plate 21 to complete the alignment of the railings. At the same time, the guide rails 23 on one side of the side plate 21 are used to facilitate the lifting and lowering of the drilling mechanism 1.
[0030] In this embodiment: the clamping mechanism 3 includes two worm gears 35, and two rotating shafts 31 are provided on the side of each worm gear 35 that is far apart from each other. A cam frame 32 is fixed on the upper side of each rotating shaft 31, and a worm wheel 34 is fixed on the lower side of each rotating shaft 31. An anti-slip pad 33 is adhered to the side of each cam frame 32 near the railing. Both ends of the two worm gears 35 are rotatably connected to the bottom side of the base 22. Each worm gear 35 meshes with two worm wheels 34 on the same side. A drive motor 36 is fixedly installed at the input end of the worm gear 35. The drive motor 36 is fixed on one side of the bottom of the base 22. The cam frame 32 is located on the top side of the base 22. The cam mechanism 36 is rotated by the drive motor 36. The worm gear 35 located on the front side is driven to rotate, and the two worm gears 35 drive the two worm wheels 34 on the same side to rotate synchronously. The two worm wheels 34 on the same side drive their respective rotating shafts 31 to rotate, thereby causing the two cam frames 32 located on the front side of the top of the base 22 to rotate backward, and at the same time causing the two cam frames 32 located on the rear side to rotate forward. Thus, the four cam frames 32 on the base 22 are used to clamp and fix the stacked railings. In addition, the anti-slip rubber pads 33 on each cam frame 32 can prevent the railings from sliding during drilling. Furthermore, the locking function between the worm wheels 34 and the worm gears 35 ensures the clamping force of the railings during drilling.
[0031] In this embodiment: the drilling mechanism 1 includes a movable truss 11, with two sliding guide rods 17 fixed at the bottom of the movable truss 11. Each sliding guide rod 17 has a lifting hydraulic cylinder 12 on one side. A movable plate 13 is slidably connected to the middle of the movable truss 11. A drilling motor 15 is fixed to the top of the movable plate 13. A drill bit mounting seat 16 is rotatably connected to the lower side of the movable plate 13. An adjusting hydraulic cylinder 14 is provided on one side of the movable plate 13. A concave groove is formed on the side of the two sliding guide rods 17 away from the lifting hydraulic cylinder 12, and the concave groove is sleeved on the outside of the guide rail 23. A guide groove for sliding the movable plate 13 is formed in the middle of the movable truss 11, and the adjusting hydraulic cylinder... The fixed part 14 is fixedly connected to one side of the movable truss 11, and the telescopic part of the adjusting hydraulic cylinder 14 is fixedly connected to one side of the movable plate 13. The telescopic parts of the two lifting hydraulic cylinders 12 drive the movable truss 11 to move up and down. During this process, the concave grooves on the two sliding guide rods 17 cooperate with the two guide rails 23 to allow the movable truss 11 to move up and down stably. At the same time, the telescopic part of the adjusting hydraulic cylinder 14 pushes the movable plate 13 to move to both sides within the movable truss 11, thereby adjusting the position of the drill bit under the drill bit mounting seat 16. Then, the rotating part of the drilling motor 15 drives the drill bit under the drill bit mounting seat 16 to rotate.
[0032] Working principle: In use, the two lifting hydraulic cylinders 12 are first used to move the moving truss 11 upwards. Simultaneously, the concave grooves on the two sliding guide rods 17 cooperate with the two guide rails 23, allowing the moving truss 11 to move stably. After the moving truss 11 reaches a suitable height, the drill bit to be drilled is installed on the drill bit mounting seat 16. The railings to be drilled are stacked on top of the base 22, positioned between the two front cam frames 32 and the two rear cam frames 32. Then, the adjusting hydraulic cylinder 14 is used to push the moving plate 13 to move laterally within the moving truss 11, moving the lower end of the longer drill bit to the position where a hole needs to be drilled in the railing. Subsequently, the drilling motor 15 rotates... The drill bit mounting base 16 drives the longer drill bit to start rotating at high speed. At the same time, the drive motor 36 drives the worm gear 35 located on the front side to rotate. The two worm gears 35 drive the two worm wheels 34 on the same side to rotate synchronously. The two worm wheels 34 on the same side drive their respective rotating shafts 31 to rotate, thereby causing the two cam frames 32 located on the front side of the top of the base 22 to rotate backward, and the two cam frames 32 located on the rear side to rotate forward. Thus, the four cam frames 32 on the base 22 are used to clamp and fix the stacked railings. In addition, the anti-slip rubber pads 33 on each cam frame 32 can prevent the railings from sliding during drilling. Furthermore, the locking function between the worm wheels 34 and the worm gears 35 ensures the clamping force of the railings during drilling.
[0033] Subsequently, the telescopic parts of the two lifting hydraulic cylinders 12 drive the moving truss 11 and the two sliding guide rods 17 on its lower side to move slowly downward along the guide rail 23. During this process, the high-speed rotating drill bit begins to drill holes in the uppermost railing. After the uppermost railing is completely drilled through, as the moving truss 11 continues to move downward, the drill bit begins to drill holes in the same position of the stacked second layer of railings. This can then accelerate the descent speed of the moving truss 11. During this process, the downward force of the drill bit during drilling is limited by the drilling of the top two layers of railings, thereby preventing the drill bit from deviating during subsequent drilling.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
