Description

Technical Field

[0001] This application relates to the field of drilling technology, and more specifically, to a drilling mechanism for processing metal parts. Background Technology

[0002] Drilling mechanisms for parts processing are specialized equipment used for machining holes in the production of metal parts. They are suitable for different types of metal workpieces such as steel plates, profiles, and precision parts. They can accurately drill holes of different diameters and depths according to processing requirements. The workpiece can be firmly clamped by a fixing device to prevent displacement during drilling, ensuring hole accuracy and drilling efficiency. They are suitable for the metal parts processing needs of the automotive, machinery, and hardware industries, helping to improve the quality and production efficiency of parts processing. At the same time, they can adapt to metal materials of different thicknesses and hardness, meeting diverse drilling processing scenarios.

[0003] In actual operation, drilling machines used for processing small metal parts mostly drill directly into the parts without a stable clamping and fixing structure. This can easily cause the parts to shift during the drilling process, thus affecting the accuracy of the hole position. At the same time, some drilling mechanisms rely on complex electrical control systems to operate, and the convenience of manual operation is poor, which brings inconvenience to the precise and safe drilling of small metal parts. Utility Model Content

[0004] The purpose of this application is to provide a drilling mechanism for processing metal parts, which solves the technical problems in the background art.

[0005] This application provides a drilling mechanism for processing metal parts, including a fixed plate. A fixed rod is fixedly connected to one side of the upper surface of the fixed plate. A movable plate is slidably connected to the periphery of the fixed rod. A fixed cylinder is fixedly connected to the upper end of the fixed rod. A rotating rod is rotatably inserted into the inside of the fixed cylinder. An eccentric wheel is provided at one end of the rotating rod. An insertion hole is provided above the inside of the eccentric wheel, and one end of the rotating rod is fixedly inserted into the insertion hole. A handle is fixedly connected to the other end of the rotating rod. A fixed block is rotatably connected to one side of the lower surface of the movable plate. A drill rod is detachably attached to the lower end of the fixed block. A spring damper is fixedly connected between the fixed plate and the movable plate.

[0006] Optionally, a threaded rod is fixedly connected to the lower end of the fixing plate, and the outer wall of the threaded rod is symmetrically provided with sliding grooves.

[0007] Optionally, a clamping plate is slidably connected to the periphery of the threaded rod, and a through hole is provided on one side of both the fixing plate and the clamping plate. An internal threaded cylinder is rotatably connected to the lower end of the clamping plate, and the internal threaded cylinder is rotatably connected to the threaded rod through a thread.

[0008] Optionally, the clamp plate has a through-hole, and the threaded rod is slidably inserted into the through-hole. The inner wall of the through-hole is symmetrically fixed with sliders, and the sliders are located in the groove.

[0009] Optionally, a motor is fixedly connected to one side of the upper surface of the movable plate, and the output end of the motor is fixedly connected to the fixed block.

[0010] Optionally, a support base is fixedly connected to the lower end of the threaded rod.

[0011] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0012] This application places the part to be drilled between the fixed plate and the clamping plate. Rotating the internal threaded cylinder causes the clamping plate to move upward through the threaded engagement. The slider slides along the slide groove to ensure that the clamping plate moves stably and vertically until it clamps the part together with the fixed plate, preventing the part from shifting during drilling and ensuring drilling accuracy.

[0013] Rotating the handle drives the rotating rod and eccentric wheel to rotate. The eccentric wheel presses against the moving plate, causing it to move downwards along the fixed rod, thus feeding the drill rod downwards to complete the drilling. During the feeding process, the spring damper is compressed, which buffers the feed speed of the moving plate and prevents damage to the drill rod due to excessive feed speed and cutting force, improving operational safety. After drilling is completed, rotating the handle in the opposite direction causes the spring damper to push the moving plate back to its original position, disengaging the drill rod from the part. Rotating the internal threaded cylinder in the opposite direction releases the clamp and allows the part to be removed. The entire process requires no complex electrical control system and can be completed manually, making it convenient and practical. It combines stable fixation, flexible adaptation, and safe operation, making it suitable for drilling small metal parts. Attached Figure Description

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-3 This application provides a drilling mechanism for processing metal parts, including a fixed plate 1. A fixed rod 2 is fixedly connected to one side of the upper surface of the fixed plate 1. A movable plate 3 is slidably connected to the periphery of the fixed rod 2. A fixed cylinder 4 is fixedly connected to the upper end of the fixed rod 2. A rotating rod 5 is rotatably inserted into the inside of the fixed cylinder 4. One end of the rotating rod 5 is provided with an eccentric wheel 6. An insertion hole 7 is provided above the inside of the eccentric wheel 6, and one end of the rotating rod 5 is fixedly inserted into the insertion hole 7. A handle 20 is fixedly connected to the other end of the rotating rod 5. A fixed block 9 is rotatably connected to one side of the lower surface of the movable plate 3. A motor 8 is fixedly connected to one side of the upper surface of the movable plate 3. A drill rod 10 is detachably attached to the lower end of the fixed block 9, and the output end of the motor 8 is fixedly connected to the fixed block 9. A spring damper 11 is fixedly connected between the fixed plate 1 and the movable plate 3. Rotating the handle 20 drives the rotating rod 5 and the eccentric wheel 6 to rotate. The eccentric wheel 6 presses the movable plate 3, causing it to move downward along the fixed rod 2, thus driving the drill rod 10 downward to complete the drilling. During the feeding process, the spring damper 11 is compressed, which can buffer the feeding speed of the movable plate 3 and prevent the drill rod 10 from being damaged due to excessive feeding speed and cutting force, thereby improving operational safety. After drilling is completed, rotating the handle 20 in the opposite direction causes the spring damper 11 to push the movable plate 3 back to its original position, and the drill rod 10 disengages from the component. The operation is simple and convenient.

[0020] A threaded rod 12 is fixedly connected to the lower end of the fixed plate 1. A sliding groove 13 is symmetrically opened on the outer wall of the threaded rod 12. A clamping plate 14 is slidably connected to the outer periphery of the threaded rod 12. A through hole 15 is opened through one side of both the fixed plate 1 and the clamping plate 14. An internal threaded cylinder 16 is rotatably connected to the lower end of the clamping plate 14, and the internal threaded cylinder 16 is rotatably connected to the threaded rod 12 through the thread. A sliding hole 18 is opened through the inside of the clamping plate 14, and the threaded rod 12 is slidably inserted into the sliding hole 18. A slider 19 is symmetrically fixedly connected to the inner wall of the sliding hole 18, and the slider 19 is located in the sliding groove 13. A support base 17 is fixedly connected to the lower end of the threaded rod 12. The part to be drilled is placed between the fixed plate 1 and the clamping plate 14. The internal threaded cylinder 16 is rotated to drive the clamping plate 14 to move upward through the threaded engagement. The slider 19 slides along the sliding groove 13 to ensure that the clamping plate 14 moves stably and vertically until it clamps the part together with the fixed plate 1, preventing the part from shifting during drilling and ensuring drilling accuracy.

[0021] Working principle: Place the metal part to be drilled between the fixing plate 1 and the clamping plate 14, ensuring that the drilling position on the part is aligned with the through hole 15 inside the fixing plate 1 and the clamping plate 14; then rotate the internal threaded cylinder 16 at the lower end of the clamping plate 14. The internal threaded cylinder 16 and the threaded rod 12 are connected by threads, which drives the clamping plate 14 to move upward along the threaded rod 12. At the same time, the slider 19 on the inner wall of the sliding hole 18 slides along the sliding groove 13 on the outer wall of the threaded rod 12, ensuring that the clamping plate 14 only moves vertically and does not rotate, until the clamping plate 14 is tightly attached to the lower end face of the part, and together with the fixing plate 1, clamps and fixes the part.

[0022] Start the motor 8 on one side of the upper end of the moving plate 3. The output end of the motor 8 drives the lower fixed block 9 to rotate. The detachable drill rod 10 at the lower end of the fixed block 9 rotates synchronously at high speed with the fixed block 9, providing cutting power for drilling. If it is necessary to replace the drill rod 10 with a different specification, simply disassemble the connection between the fixed block 9 and the drill rod 10 to adapt to drilling requirements of different hole diameters.

[0023] Rotate the handle 20 at the other end of the rotating rod 5. The rotating rod 5 rotates inside the fixed cylinder 4. One end of the rotating rod 5 is fixedly inserted into the insertion hole 7 of the eccentric wheel 6, driving the eccentric wheel 6 to rotate synchronously. During the rotation of the eccentric wheel 6, its eccentric structure continuously presses the upper surface of the moving plate 3, pushing the moving plate 3 to slide downward along the fixed rod 2. The moving plate 3 drives the lower motor 8, the fixed block 9 and the high-speed rotating drill rod 10 to move downward synchronously. The drill rod 10 gradually approaches and contacts the metal parts, and drills holes in the parts through the cutting action of high-speed rotation, realizing the drilling feed action.

[0024] During the downward feeding of the moving plate 3, the spring damper 11 between the fixed plate 1 and the moving plate 3 is compressed. The spring damper 11 generates a compressive force, which can buffer the feed speed of the moving plate 3 and prevent the drill rod 10 from being damaged by excessive cutting force due to excessive feed. After drilling is completed, the handle 20 is rotated in the opposite direction, the squeezing force of the eccentric wheel 6 on the moving plate 3 disappears, and the spring damper 11 pushes the moving plate 3 to reset upward along the fixed rod 2 under its own elastic force, which drives the drill rod 10 to detach from the parts and completes one drilling operation.

[0025] To remove a component, rotate the internal threaded cylinder 16 in the opposite direction to move the clamping plate 14 downwards along the threaded rod 12, releasing the clamping of the component. The machined component can then be removed from between the fixing plate 1 and the clamping plate 14. Repeat the above operation to perform drilling on the next metal component. The entire process does not require a complex electrical control system and can be completed manually.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
