Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and more specifically, to a drilling device for the production of ship parts. Background Technology

[0002] Drilling is a common and crucial process in the production of ship parts. Traditional drilling equipment for ship parts is typically simple in structure and limited in function. Most are equipped with only a single drill bit, resulting in low drilling efficiency. Furthermore, traditional equipment is cumbersome to operate and has poor positioning accuracy when fixing ship parts of different sizes and shapes. Existing equipment is often inflexible and inconvenient in terms of height adjustment, requiring complex adjustments using additional tools. A device that can easily adjust the height of workpieces and facilitate simultaneous drilling in multiple locations would greatly improve production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a drilling device for the production of ship parts. The motor drives the first gear to rotate, which causes multiple second gears to rotate simultaneously, thereby driving multiple drill bits to work synchronously. Compared with the traditional single-drill-bit drilling device, the drilling efficiency is greatly improved, and multiple holes can be drilled at the same time.

[0004] A drilling device for manufacturing ship parts includes a fixed frame, a cylinder fixedly connected to the lower side of the fixed frame, a telescopic rod of the cylinder fixedly connected to a cavity, a motor fixedly installed inside the cavity, the output shaft of the motor fixedly connected to the center of a first gear, several fixed shafts evenly arranged in a circle fixedly installed on the upper side of the cavity, the lower side of the fixed shafts rotatably connected to the central shaft of a second gear, the second gear meshing with the first gear, the lower end of the central shaft of the second gear passing through the lower side of the cavity, and the lower end of the central shaft of the second gear fixedly connected to the upper end of a drill bit.

[0005] The fixing frame is fixedly connected to the column, and the column is fixed on the base.

[0006] As a further limitation of this technical solution, the column is connected to a support assembly, which can move up and down along the column. The support assembly is used to support the workpiece, which is placed under the drill bit. The support assembly includes a support plate, and a placement plate is fixedly installed on the upper side of the support plate. Positioning blocks are fixedly installed at the middle positions of adjacent sides of the placement plate. Limiting grooves are respectively opened on the other two sides of the placement plate corresponding to the positions of the positioning blocks. An electric push rod is fixedly installed in each limiting groove. The telescopic rod end of each electric push rod is fixedly connected to a top block. The top block and the positioning block are arranged face to face. The workpiece can be placed on the placement plate, and the workpiece can be fixed by the positioning block and the top block.

[0007] As a further limitation of this technical solution, a movable ring is fixedly connected to the middle of one side of the support plate, and a handle is fixedly connected to the movable ring. An opening is provided on the movable ring. The arc-shaped wall of the column is provided with serrations from top to bottom. A groove is provided on the movable ring corresponding to the position of the serrations. The serrations are located in the grooves, and the surface of the grooves can abut against the serrations. Ear blocks are fixedly connected to both ends of the movable ring corresponding to the opening. One ear block is passed through by a bolt. A handle is fixed to one end of the bolt, and the bolt is screwed to the other ear block. The two ear blocks can be locked by the bolt.

[0008] As a further limitation of this technical solution, the saw teeth are elastic rubber teeth. When the two ear blocks tighten and drive the two ends of the moving ring to tighten, the saw teeth can be elastically shaped under the pressure of the groove on the side corresponding to the saw teeth.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are:

[0010] The positioning block on the support assembly and the top block driven by the electric push rod cooperate with each other and can be flexibly adjusted according to the size of the workpiece to achieve precise positioning and firm fixation of workpieces of different shapes and sizes, effectively ensuring the accuracy of the drilling position.

[0011] The motor drives the first gear to rotate, causing multiple second gears to rotate simultaneously, which in turn drives multiple drill bits to work synchronously. Compared with traditional single-drill-bit drilling devices, this greatly improves drilling efficiency and enables drilling of multiple holes at the same time.

[0012] The moving ring of the support assembly engages with the serrations on the column, allowing for easy vertical movement and fixation of the support assembly via bolts and a handle. Furthermore, the serrations are made of elastic rubber, which deforms elastically when the moving ring is tightened, enhancing the stability of the fixation. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in terms of the embodiments and implementation methods.

[0019] A drilling device for manufacturing ship parts includes a fixed frame 1, a cylinder 13 fixedly connected to the lower side of the fixed frame 1, a telescopic rod of the cylinder 13 fixedly connected to a cavity 12, a motor 23 fixed inside the cavity 12, the output shaft of the motor 23 fixedly connected to the center of a first gear 20, a plurality of circumferentially evenly arranged fixed shafts 22 fixed to the upper side of the cavity 12, the lower side of the fixed shafts 22 rotatably connected to the central shaft of a second gear 21, the second gear 21 meshing with the first gear 20, the lower end of the central shaft of the second gear 21 passing through the lower side of the cavity 12, and the lower end of the central shaft of the second gear 21 fixedly connected to the upper end of a drill bit 11.

[0020] The fixing frame 1 is fixedly connected to the column 3, and the column 3 is fixed on the base 4.

[0021] In this embodiment, cylinder 13 is activated, and the extension rod of cylinder 13 moves cavity 12 downward, bringing drill bit 11 closer to workpiece 10. Simultaneously, motor 23 is activated, and its output shaft drives first gear 20 to rotate. Since first gear 20 meshes with multiple second gears 21, the rotation of first gear 20 drives multiple second gears 21 to perform circular motion around fixed shaft 22. Drill bit 11, fixed to the lower end of the central shaft of the second gears 21, rotates accordingly, performing drilling operations on the ship fittings below.

[0022] The column 3 is connected to a support assembly, which can move up and down along the column 3. The support assembly is used to support the workpiece 10, which is placed under the drill bit 11. The support assembly includes a support plate 5, and a placement plate 6 is fixedly installed on the upper side of the support plate 5. Positioning blocks 19 are fixedly installed at the middle positions of the two adjacent sides of the placement plate 6. Limiting grooves 8 are respectively opened on the other two sides of the placement plate 6 corresponding to the positions of the positioning blocks 19. An electric push rod 7 is fixedly installed in each limiting groove 8. The telescopic rod end of each electric push rod 7 is fixedly connected to a top block 9. The top block 9 and the positioning block 19 are arranged face to face. The workpiece 10 can be placed on the placement plate 6, and the workpiece 10 can be fixed by the positioning block 19 and the top block 9.

[0023] In this embodiment, the ship fittings are placed on the placement plate 6, and the electric push rod 7 is activated according to the size of the workpiece 10. The telescopic rod of the electric push rod 7 pushes the top block 9 to move towards the positioning block 19 until the positioning block 19 and the top block 9 are tightly attached to both sides of the workpiece 10, thereby achieving precise positioning and firm fixation of the workpiece 10.

[0024] A movable ring 302 is fixedly connected to the middle of one side of the support plate 5. The movable ring 302 is fixedly connected to a handle 303. An opening 15 is provided on the movable ring 302. The arc-shaped wall of the column 3 is provided with serrations 301 from top to bottom. A groove 14 is provided on the movable ring 302 corresponding to the position of the serrations 301. The serrations 301 are located in the groove 14. The surface of the groove 14 can abut against the serrations 301. Ear blocks 16 are fixedly connected to both ends of the movable ring 302 corresponding to the opening 15. One ear block 16 is passed through by a bolt 18. One end of the bolt 18 is fixed to a handle 17. The bolt 18 screws the other ear block 16. The two ear blocks 16 can be locked by the bolt 18.

[0025] The saw teeth 301 are elastic rubber teeth. When the two ear blocks 16 tighten and drive the two ends of the moving ring 302 to tighten, the saw teeth 301 can be elastically shaped under the pressure of the groove 14 on the side corresponding to the saw teeth 301.

[0026] In this embodiment, the bolt 18 is loosened, and the movable ring 302 is pushed by the handle 303. Since the serrations 301 in the groove 14 of the movable ring 302 are elastic, they can move flexibly on the serrations 301 of the column 3, realizing the up-and-down movement of the support assembly along the column 3. After adjusting to a suitable height, the bolt 18 is tightened, and the lug 16 tightens, causing the two ends of the movable ring 302 to tighten. The groove 14 squeezes the serrations 301, causing the serrations 301 to undergo elastic deformation, thereby firmly fixing the movable ring 302 to the column 3, completing the height adjustment of the support assembly.

[0027] The method of using this utility model is as follows: Clean the ship parts to be drilled, check whether all components of the device are intact, and ensure that the cylinder 13, motor 23, electric push rod 7, and other equipment are operating normally. Place the ship parts on the placement plate 6. According to the size of the workpiece 10, start the electric push rod 7, adjust the position of the top block 9, and make the positioning block 19 and the top block 9 tightly fix the workpiece 10. Loosen the bolt 18, move the moving ring 302 through the handle 303, adjust the support assembly to a suitable height, and then tighten the bolt 18 to fix the support assembly. Start the cylinder 13 to bring the drill bit 11 close to the workpiece 10. Then start the motor 23, and the drill bit 11 begins to rotate to drill a hole in the ship parts. During the drilling process, it is necessary to observe the drilling situation to ensure the drilling quality. After drilling is completed, first turn off the motor 23, then retract the cylinder 13 extension rod to raise the drill bit 11. Loosen the top block 9 and remove the drilled ship parts.

[0028] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
