Abstract

Technical Field
[0001] This utility model relates to the field of shipbuilding equipment technology, and in particular to a drilling device for shipbuilding. Background Technology
[0002] In the shipbuilding industry, drilling is a crucial process in hull structure assembly, equipment installation, and pipeline connection, directly affecting the ship's construction quality, structural strength, and assembly precision. Ship components are mostly made of high-strength steel (such as marine low-carbon steel and high-strength alloy structural steel), and are characterized by large size, uneven thickness, and complex shapes (such as curved panels, ribs, and bulkheads), which places stringent requirements on the stability, precision, adaptability, and operational efficiency of drilling equipment.
[0003] However, in the current technology, for on-site operation scenarios, the drilling equipment is usually fixed to the workpiece surface by temporary methods such as expansion bolts and heavy objects. Each time the drilling position is changed, the fixing device needs to be disassembled and the positioning needs to be recalibrated. Each adjustment is time-consuming. For components with multiple holes, repeated disassembly and assembly leads to a significant reduction in work efficiency and drilling efficiency. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0018] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a drilling device for shipbuilding, including a mounting plate 1 and a drilling mechanism 11. A clamping mechanism 2 is provided at one end of the mounting plate 1, and a position adjustment mechanism 3 is provided at the upper end of the mounting plate 1. The clamping mechanism 2 includes two sets of fixed seats 21. Rotating frames 22 are rotatably installed inside the two mating seats at the other end of the frame plate 1. Cylinders 23 are installed inside the two sets of rotating frames 22. Two sets of rotating rods 24 are rotatably installed in the middle of the two sets of fixed seats 21. Two sets of clamping heads 25 are fixedly installed on the outer walls of the two sets of rotating rods 24. Cranks 26 are installed on the outer walls of the two sets of rotating rods 24. Connecting parts 27 are rotatably installed on the outer walls of the two sets of cranks 26. Auxiliary gears 28 are installed on the outer walls of the two sets of rotating rods 24, and the two sets of auxiliary gears 28 mesh with each other. Guide recesses 29 are installed on one side of the two sets of fixed seats 21. The protruding ends of the two sets of cylinders 23 pass through the two reserved holes of the mating frame plate 1 and are respectively fixed to one end of the two sets of connecting parts 27.
[0019] The specific settings and functions of this embodiment are described below. The frame plate 1 serves as the basic support structure of the device. One end is equipped with a clamping mechanism 2 for fixing the device, and the upper end is equipped with a position adjustment mechanism 3 for adjusting the drilling position. The drilling mechanism 11 is integrated on the position adjustment mechanism 3 to achieve precise drilling operations on ship components. The clamping mechanism 2 is used to stably fix the entire device on the ship workpiece, and simultaneously adjusts the position of the device on the workpiece. Two sets of fixed seats 21 are provided as the mounting base for the clamping mechanism 2, providing stable support for other components. The rotating frame 22 is rotatably mounted inside two mating seats at the other end of the mating frame plate 1, and can adaptively rotate according to the workpiece surface angle to ensure clamping stability. The cylinder 23 is installed inside the two sets of rotating frames 22, serving as the power source for the clamping action and providing stable driving force. Two sets of rotating rods 24 are rotatably mounted in the middle of the two sets of fixed seats 21, and their rotation drives the clamping heads 25 to move. The clamping heads 25 are fixedly mounted on the outer walls of the two sets of rotating rods 24, with two sets on each set of rotating rods 24, for a total of four sets of clamping heads 25. Synchronous action achieves clamping of the workpiece. The clamping head 25, made of high-strength alloy material, is designed to clamp or release the workpiece. Its inner side features anti-slip textures and wear-resistant rubber pads, ensuring clamping force while preventing damage to the workpiece surface. Cranks 26 are mounted on the outer walls of the two sets of rotating rods 24, serving as force transmission components and converting the linear motion of the cylinder 23 into the rotational motion of the rods 24. Connecting parts 27 are rotatably mounted on the outer walls of the two sets of cranks 26, with one end fixed to the extended end of the cylinder 23, achieving a movable connection between the cylinder 23 and the cranks 26. Two sets of auxiliary gears 28 are respectively mounted on the outer walls of the two sets of rotating rods 24 and mesh with each other, ensuring that the two sets of rotating rods 24 rotate synchronously in opposite directions, thus coordinating the movements of the clamping head 25. Guide recesses 29 are mounted on one side of the two sets of fixed seats 21, guiding and limiting the movement trajectory of the clamping head 25 to ensure accurate and reliable clamping. Working principle of clamping mechanism 2: When cylinder 23 extends or retracts, it drives crank 26 to rotate through connecting piece 27. Under the meshing action of auxiliary gear 28, two sets of rotating rods 24 rotate synchronously in opposite directions, thereby driving four sets of clamping heads 25 to open or close simultaneously, realizing the clamping and fixing or loosening adjustment of the workpiece. The extended end of cylinder 23 passes through two reserved holes of the mating frame plate 1 to ensure the stability of power transmission.
[0020] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the position adjustment mechanism 3 includes a frame 31, a sliding plate 32 slidably mounted on the upper end of the frame 31, a square hole seat 33 mounted on one end of the sliding plate 32, a push plate 34 provided on one side of the frame 31, two sets of first telescopic rods 35 installed inside the frame 31, a round hole plate 36 provided below the square hole seat 33, and second telescopic rods 37 installed on the upper end of the square hole seat 33 and near the four corners. The lower end of the frame 31 is fixed to the upper end of the cooperating frame plate 1. The protruding ends of the two sets of first telescopic rods 35 pass through one end of the frame 31 and are fixed to one end of the push plate 34. The upper end of the push plate 34 is fixed to the lower end of the square hole seat 33. The protruding ends of the four sets of second telescopic rods 37 pass through the upper end of the square hole seat 33 and are fixed to the upper end of the round hole plate 36. A drilling mechanism 11 is located inside the square hole seat 33, and the lower end of the drilling mechanism 11 is fixed to the upper end of the round hole plate 36.
[0021] The overall effect of this embodiment is as follows: the position adjustment mechanism 3 is used to precisely adjust the spatial position of the drilling mechanism 11 to meet the drilling requirements at different positions; the frame 31 serves as the base frame 31 of the position adjustment mechanism 3, with its lower end fixed to the upper end of the mating frame plate 1, providing stable support for the entire adjustment mechanism; the sliding plate 32 is slidably installed on the upper end of the frame 31 and can slide horizontally along the frame 31 to achieve lateral position adjustment of the drilling mechanism 11; the square hole seat 33 is installed on one end of the sliding plate 32, serving as the mounting carrier for the drilling mechanism 11 and providing an installation position for the second telescopic rod 37; the push plate 34 is disposed on one side of the frame 31, with its upper end fixed to the lower end of the square hole seat 33, for transmission... The first telescopic rod 35 is driven by two sets of first telescopic rods 35 installed inside the frame 31. The protruding ends of the first telescopic rods 35 all pass through one end of the frame 31 and are fixed to one end of the push plate 34. As a power source for lateral adjustment, the push plate 34 and the square hole seat 33 are moved laterally by telescopic movement. The round hole plate 36 is set below the square hole seat 33 and is used to install and fix the drilling mechanism 11. The second telescopic rod 37 is installed on the upper end of the square hole seat 33 and near the four corners. The protruding ends of the second telescopic rods 37 all pass through the upper end of the square hole seat 33 and are fixed to the upper end of the round hole plate 36. As a power source for vertical adjustment, the round hole plate 36 and the drilling mechanism 11 are moved up and down by synchronous telescopic movement. The working principle of the position adjustment mechanism 3: By extending and retracting the first telescopic rod 35, the push plate 34 is pushed to drive the square hole seat 33 and the sliding plate 32 to slide laterally along the frame 31, thereby realizing the horizontal position adjustment of the drilling mechanism 11; by synchronously extending and retracting the four sets of second telescopic rods 37, the round hole plate 36 and the drilling mechanism 11 are driven to move up and down, thereby realizing the vertical position adjustment of the drilling mechanism 11. The two work together to achieve precise positioning of the drilling mechanism 11 in two-dimensional space; the drilling mechanism 11 is set inside the square hole seat 33, and its lower end is fixed to the upper end of the round hole plate 36. The position is adjusted according to the movement of the position adjustment mechanism 3. The drilling mechanism 11 includes a drive motor, a transmission shaft and a drill bit assembly. The drive motor drives the drill bit to rotate through the transmission shaft to realize the drilling operation. The drill bit assembly adopts a quick-change structure, and different specifications of drill bits can be replaced as needed to meet the drilling requirements of different hole diameters.
[0022] How to use and how to work this device: First, in the clamping and fixing stage: the cylinder 23 extends and retracts to drive the connecting piece 27, which in turn drives the two sets of rotating rods 24 to rotate via the crank 26. Under the meshing action of the auxiliary gear 28, the four sets of clamping heads 25 open and close synchronously. When closed, the clamping heads 25 tightly clamp the workpiece to complete the device fixing; when released, the device can be pushed to move on the workpiece surface to adjust the working area, and the guide recess 29 ensures that the clamping action is smooth. Then, in the position adjustment stage: the first telescopic rod 35 extends and retracts to push the push plate 34, which drives the square hole seat 33 and the sliding plate 32 to slide laterally along the frame 31, thereby realizing the horizontal position adjustment of the drilling mechanism 11; the four sets of second telescopic rods 37 extend and retract synchronously, and drive the drilling mechanism 11 to rise and fall vertically through the round hole plate 36 to complete the height positioning. Finally, the drilling operation stage: After the position is determined, the drive motor of the drilling mechanism 11 drives the drill bit to rotate, and based on the positioning of the position adjustment mechanism 3, it performs precise drilling on the ship components.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
