Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, and in particular to a chamfering and deburring mechanism for fitters. Background Technology

[0002] A fitter's chamfering and deburring mechanism is a device used to chamfer and remove burrs from the edges of workpieces. In existing technology, a clamping mechanism is commonly used to hold the workpiece during chamfering and deburring. However, when the workpiece is small, even with the clamping mechanism open, the hand operating space is still very limited, making it difficult to accurately reach in and stably grasp the workpiece, increasing the difficulty of removal. Furthermore, due to the small size of the workpiece, the contact area when gripping with fingers or tools is limited, failing to provide sufficient friction and gripping force, causing the workpiece to easily slip, requiring repeated operations and severely impacting removal efficiency. In addition, manual tools such as files and scrapers are commonly used for chamfering and deburring workpieces, a processing method that is inefficient and makes it difficult to guarantee consistent accuracy. Utility Model Content

[0003] The purpose of this invention is to address the problems in existing technologies where clamping mechanisms for small workpieces suffer from limited operating space, making them difficult to grip, and the small contact area leading to easy slippage, thus affecting retrieval efficiency. Furthermore, manual workpiece processing suffers from low efficiency and difficulty in ensuring consistent precision. This invention proposes a chamfering and deburring mechanism for fitters.

[0004] The technical solution of this utility model is as follows: a chamfering and deburring mechanism for fitters, comprising a robotic arm and a bolt, wherein the robotic arm is provided with a pair of clamps for holding the bolt, and further comprising: a spring mechanism provided at one end of the clamps to push the bolt out automatically; a positioning support plate fixedly connected to the bottom of the robotic arm, wherein the upper surface of the positioning support plate is provided with a processing mechanism for chamfering and deburring the bolt.

[0007] Optionally, the bottom of the drilling machine is provided with a positioning plate.

[0008] Optionally, the bolt is provided with a through hole for the machining mechanism to chamfer and deburr.

[0009] Optionally, each of the pair of clamps is provided with a slot, and a rubber layer is fixedly connected inside the slot.

[0010] Optionally, each of the clamps has multiple linearly arranged toothed grooves for securing the bolts.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This invention utilizes the cooperation of a robotic arm, bolts, chucks, a spring-loaded mechanism, and a processing mechanism. A spring-loaded mechanism is installed on the chuck holding the bolt workpiece, allowing small-volume bolts to automatically eject when the chuck opens, effectively solving the problems of inconvenience and low efficiency associated with manual workpiece handling.

[0024] Example

[0025] like Figures 1 to 4As shown, this utility model proposes a chamfering and deburring mechanism for fitters, including a robotic arm 6 and a bolt 9. The bolt 9 has a through hole 8 for chamfering and deburring the bolt 9. The through hole 8 and the chamfering and deburring of the bolt 9 are crucial. From an assembly perspective, burrs easily scratch the internal threads of nuts and the walls of holes in connected parts, affecting assembly accuracy and part lifespan. Chamfering and deburring ensures a tight and smooth fit, avoiding uneven gaps and localized wear. Simultaneously, the chamfer provides guidance for bolt 9 insertion, significantly improving assembly efficiency and success rate, especially in automated assembly, preventing burrs from hindering bolt 9 from being screwed in or inserted. From a safety and performance perspective, sharp burrs pose a risk of scratching operators; removing them eliminates this safety hazard. Furthermore, burrs easily accumulate corrosive substances such as moisture and dust, accelerating bolt 9 corrosion. Chamfering and deburring smooths the surface, reducing the adhesion of corrosive media and enhancing corrosion resistance. In addition, for high-end machinery and automotive parts with high appearance requirements, chamfering and deburring makes the bolt 9 more aesthetically pleasing and neat, improving the overall quality and grade of the product. The robotic arm 6 is equipped with a pair of clamping bolts 9 and chucks 10. A positioning support plate 1 is fixedly connected to the bottom of the robotic arm 6. The positioning support plate 1 plays a crucial role in supporting multiple devices. Through a precise positioning structure or reference surface, it ensures accurate device installation, maintains a fixed relative position between devices, achieves precise fit, and improves product processing accuracy. Simultaneously, it provides stable support for the equipment, distributes load and vibration, prevents equipment swaying and displacement, ensures equipment performance and lifespan, and reduces processing errors.

[0026] Among them, such as Figure 4 As shown, one end of the chuck 10 is equipped with a spring-loaded mechanism that automatically releases the push bolt 9. The spring-loaded mechanism includes a telescopic groove 13 at the end of the chuck 10. A return spring 14 is fixedly connected inside the telescopic groove 13. The return spring 14 causes the telescopic spring rod 15, which is not stuck, to rotate and pop out after being charged. The telescopic spring rod 15 is slidably connected inside the telescopic groove 13. One end of the telescopic spring rod 15 inserted into the telescopic groove 13 is fixedly connected to the return spring 14.

[0027] In addition, such as Figure 1As shown, the upper surface of the positioning support plate 1 is equipped with a processing mechanism for chamfering and deburring bolts 9. The processing mechanism includes a camera bracket 3, a hand-punch gun bracket 5, and a drill press 7, all fixedly connected to the positioning support plate 1. A positioning plate 71 is located at the bottom of the drill press 7, a high-precision camera 2 is located at the top of the camera bracket 3, and a hand-punch gun 4 is located at the top of the hand-punch gun bracket 5. The robotic arm 6, high-precision camera 2, hand-punch gun 4, and drill press 7 work together to chamfer and deburr the workpiece, based on multi-dimensional precision coordination. The high-precision camera 2 positions the workpiece through visual recognition and transmits its position and posture information to the robotic arm 6 for precise positioning. The robotic arm 6, with its flexible programmable characteristics, drives the hand-punch gun 4 and drill press to move along a preset trajectory, collaboratively completing the processing. During processing, the robotic arm 6 senses the processing force through a force sensor and adjusts its movement and force in real time to avoid workpiece damage. The entire system is automated through programming. From image acquisition and robotic arm 6 control to processing operations, each link is closely connected, forming an efficient and stable process, significantly improving the efficiency and quality of chamfering and deburring.

[0028] It is worth noting that, such as Figure 4 As shown, each pair of chucks 10 is provided with a slot 101. The shape and size of the slot 101 match the workpiece, accurately defining the workpiece's position and ensuring it maintains a fixed posture and position during processing or assembly, thus guaranteeing processing accuracy and assembly precision. The chucks 10 contact the workpiece through the slots 101, evenly distributing the clamping force across the workpiece surface. This prevents deformation or damage due to excessive localized force, which is especially important for thin-walled or easily deformable workpieces. A rubber layer 11 is fixedly connected inside each slot 101. The soft rubber layer 11 prevents direct contact between the slot 101 and the workpiece, avoiding scratches and indentations on the workpiece surface during clamping. Simultaneously, the rubber's good elasticity and high coefficient of friction increase the friction between the chucks 10 and the workpiece, making the clamping more stable and effectively preventing slippage or displacement of the workpiece during processing.

[0029] Furthermore, such as Figures 2 to 4 As shown, the chuck 10 has multiple linearly arranged grooves 12 for holding the bolts 9. These grooves 12 significantly increase friction by increasing the contact area and surface roughness, thus firmly clamping the workpiece and ensuring machining accuracy and stability. Simultaneously, the grooves 12 allow for flexible control of the clamping force by adjusting the meshing degree, preventing damage to the workpiece. Furthermore, the grooves 12 can also mate with irregular or specially shaped workpiece surfaces, enhancing the chuck's adaptability and versatility to workpieces of different shapes and sizes.

[0030] In this embodiment, when using a fitter's chamfering and deburring mechanism, simply open a pair of chucks 10 on the robotic arm 6, first insert the bolt 9's screw into the slot 101 within the chuck 10, and then have the hexagonal head of the bolt 9 engage the telescopic spring rods 15 at the ends of multiple chucks 10. Next, press the hexagonal head into the telescopic groove 13, ensuring the hexagonal head tightly engages the end of the telescopic spring rod 15. Simultaneously, activate the pair of chucks 10 to tightly clamp the bolt 9's screw, thereby enabling the high-precision camera 2, punch gun 4, drill press 7, and positioning plate 71 to process the bolt 9 and through hole 8. After processing, simply place the bolt 9 in the area where it is to be pre-emerged. After opening the pair of chucks 10, the telescopic spring rod 15, through the elastic thrust of the return spring 14 within the telescopic groove 13, causes the telescopic spring rod 15 to spring the hexagonal head of the bolt 9, finally allowing the bolt 9 to quickly and automatically emerge from the middle of the pair of chucks 10, allowing the prepared hand to catch the processed bolt 9, making the process convenient and quick.
