Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a robot deburring device for machining. Background Art

[0002] In modern manufacturing, the development of machining is of vital importance. With the continuous improvement of the requirements for precision and quality of mechanical parts, deburring has become an indispensable part of the machining process. Deburring is aimed at removing various tiny and irregular protrusions generated during the machining process. These burrs not only affect the appearance of the parts, but also have a key impact on their assembly accuracy, performance and life. The emergence of a robotic deburring device for machining has provided strong support for improving machining quality and efficiency. It combines the precision and automation characteristics of robotic technology, can efficiently complete deburring tasks, and adapt to the needs of large-scale, high-precision production in modern industry.

[0003] In terms of mechanical structure, existing deburring devices usually use a more traditional robotic arm with a fixed deburring tool. The movement of the robotic arm relies on preset programs and tracks, with limited accuracy and insufficient flexibility when facing workpieces with complex shapes. Deburring tools are mostly of a single type and are difficult to adapt to the needs of workpieces of various materials and shapes. In terms of technical principles, some devices rely on simple pressure contact and friction to remove burrs, and rely on relatively rough sensing methods for locating burrs, such as some contact sensors that can only detect the general outline of the workpiece. This sensing method is prone to errors, resulting in incomplete deburring or unnecessary damage to the workpiece surface. In addition, the power system of the traditional device is not stable enough, and after working for a long time, it is easy to have unstable power output, which affects the effect and efficiency of deburring.

[0004] In the current deburring technology, the replacement method of the grinding rod is extremely cumbersome. Generally speaking, replacing the grinding rod requires shutting down the equipment first, and then disassembling and installing it with complex tools. Due to the unreasonable design of the equipment structure, multiple components need to be disassembled step by step during the disassembly process, and parts are easily damaged during the disassembly process. In addition, when installing a new grinding rod, fine calibration and debugging work is required to ensure that it can work normally. This series of processes consumes a lot of time and manpower, seriously affecting production efficiency, resulting in frequent production interruptions due to untimely replacement of the grinding rod during the production process. Therefore, a robot deburring device for machining is proposed to solve the above problems. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Reference Figure 1 - Figure 4, the utility model provides an embodiment: a robot deburring device for machining, including a cabinet 1, a side wall of the cabinet 1 is provided with an observation window 5, the observation window 5 is made of high-strength transparent organic glass, has good transparency and impact resistance, and is convenient for staff to observe the working conditions inside the cabinet 1, the side wall of the cabinet 1 is provided with a transport component, the transport component is used to transport the material to be polished, a mechanical arm 6 is fixedly connected to the inside of the cabinet 1, the joint part of the mechanical arm 6 is driven by a high-precision servo motor, the servo motor has precise position control and fast response capability, and can realize precise adjustment of the mechanical arm 6 at different angles and positions, a clamping head 7 is fixedly connected to the side wall of the mechanical arm 6, and a hydraulic clamping device is provided inside the clamping head 7, which is controlled by the controller 4 The size of the clamping force can be accurately controlled to ensure that the material can be grasped stably without causing damage to the material. The side wall of the cabinet 1 is fixedly connected to a controller 4, which can accurately control the mechanical arm 6, the drive motor 10 and the transport component, etc., to realize the automation of the entire deburring process. The inner wall of the cabinet 1 is provided with a grinding component, which is used to grind and deburr the material. The grinding component includes a base 8, which has good stability and shock absorption performance and can provide stable support for the grinding component. The upper surface of the base 8 has high flatness, ensuring that the bracket 9 can be vertically fixed on the base 8. The bottom of the base 8 is fixedly connected to the inner wall of the cabinet 1, and the top of the base 8 is fixedly connected to the bracket 9. The bracket 9 is made of steel as a supporting structure. It has good bending and compression resistance. The bracket 9 is fixedly connected to a driving motor 10. The output end of the driving motor 10 is fixedly connected to a threaded base 15. The threaded base 15 is slidably connected to a plurality of rolling balls 14. The rolling balls 14 are distributed in a circular shape inside the rolling balls 14, which can provide flexible sliding and locking functions when the grinding rod 11 is installed and disassembled. The outer wall of the threaded base 15 is provided with a threaded rotating block 13. The threaded rotating block 13 is made of stainless steel, and its outer surface is processed with anti-slip threads to facilitate manual operation by the staff. The internal thread of the threaded rotating block 13 matches the external thread of the threaded base 15, and relative movement is achieved through thread matching. The inner wall of the threaded rotating block 13 is slidably connected to the outer wall of the threaded base 15, and the inner wall of the threaded base 15 is slidably connected to the outer wall of the threaded base 15. The wall is slidably connected to a grinding rod 11, which is made of a cemented carbide material. This material has high hardness and wear resistance and can effectively grind and remove burrs on the material. Its outer wall has been finely processed, and the surface is smooth and tightly matched with the threaded base 15. A ball groove 12 is provided on the outer wall of the grinding rod 11. The ball groove 12 on the outer wall of the grinding rod 11 matches the size of the ball 14, which can achieve a good locking effect. The transport component includes a conveyor platform 2. The conveyor platform 2 has high strength and stability and can withstand the weight of the material tray 3 and the material to be polished. A transmission chain is provided inside it, which can operate smoothly under the drive of the motor to achieve accurate transportation of the material tray 3. The side wall of the conveyor platform 2 is fixedly connected to the side wall of the cabinet 1.The inner wall of the conveyor table 2 is slidably connected to a material tray 3. The surface of the material tray 3 is designed with anti-slip patterns and positioning grooves. The anti-slip patterns can prevent the material to be polished from sliding on the tray, and the positioning grooves can ensure the accurate position of the material on the tray, making it convenient for the gripping head 7 on the robot arm 6 to perform the grasping operation.

[0036] Specifically, when using the device, the conveyor platform 2 starts to transport the material tray 3. After the material tray 3 is transported to the side wall of the cabinet 1, the mechanical arm 6 inside the cabinet 1 starts to work. The mechanical arm 6 grabs the material to the top of the base 8 and prepares for grinding and deburring operations. When a different grinding rod 11 needs to be replaced, the staff first rotates the threaded rotating block 13 toward the bottom of the threaded base 15. As the threaded rotating block 13 rotates and moves, its inner wall gradually squeezes the rolling ball 14 inside the threaded base 15. When the threaded rotating block 13 rotates downward, the rolling ball 14 gradually loses lateral accumulated pressure and becomes able to slide. At this time, the staff can manually remove the grinding rod 11, and then replace it with a new grinding rod 11 and insert the new grinding rod 11 Inside the threaded base 15, when the ball groove 12 at the end of the grinding rod 11 is located at the position of the ball 14, the staff rotates the threaded rotating block 13 in the opposite direction again. The threaded rotating block 13 moves upward during the rotation, and its inner wall gradually squeezes the ball 14, causing the ball 14 to slide into the ball groove 12. After the ball 14 is embedded in the ball groove 12, the grinding rod 11 is locked by the friction between the ball 14 and the ball groove 12 and the squeezing effect of the threaded rotating block 13. Through such an operation, the grinding rod 11 is unlocked and locked, thereby achieving the effect of quickly and efficiently replacing the grinding rod 11, meeting the needs of grinding and deburring of different materials, and improving the working efficiency and flexibility of the deburring device of the machining robot.

[0037] Reference Figure 5 - Figure 6, a negative pressure fan 20 is fixedly connected to the bottom of the inner wall of the base 8. The blades of the negative pressure fan 20 are made of engineering plastics. After special aerodynamic design, the shape and angle of the blades can ensure that a strong negative pressure suction force is generated when rotating at high speed. A filter plate 16 is fixedly connected to the inner wall of the base 8. The filter plate 16 is composed of a stack of metal filter screens. The filter screens are made of stainless steel. The aperture of the outer filter screen is relatively large, which can intercept larger particles of debris and prevent them from hindering subsequent collection and cleaning work; the aperture of the inner filter screen gradually becomes smaller, forming a gradient filtration structure, which can more effectively filter fine dust particles. A slide groove 19 is provided on the side wall of the base 8. The inner wall of the slide groove 19 is precisely processed, the surface is smooth and coated with a lubricating coating, which can reduce the collection box 1 7 Friction during the sliding process, the inner wall of the slide 19 is slidably connected to the collection box 17, and the side wall of the collection box 17 is fixedly connected to the handle 18. A drop hole 28 is provided on the side wall of the base 8. The inner wall of the drop hole 28 is smoothed and has a certain inclination angle, which can guide the debris to fall smoothly into the collection box 17. A cleaning brush 25 is provided on the top of the filter plate 16. The bristles of the cleaning brush 25 are made of nylon. The nylon bristles have good flexibility and wear resistance, and can effectively sweep up the debris without damaging the filter plate 16. It can ensure that the surface of the filter plate 16 is fully cleaned. The brush handle of the cleaning brush 25 is made of aluminum alloy. One end of the brush handle is slidably connected to the slide groove 3 27 on the inner wall of the base 8 through the slider, and the slider is kept between the inner wall of the slide groove 3 27. Maintaining a very small gap can not only ensure the stability of the cleaning brush 25 during movement, but also enable it to slide smoothly and sweep the debris into the drop hole 28. The cleaning brush 25 is slidably connected to the upper surface of the filter plate 16. A slide groove 3 27 is provided on the inner wall of the base 8. One end of the cleaning brush 25 is slidably connected to the inner wall of the slide groove 3 27. The base 8 is fixedly connected to the inside of the driving motor 21. The outer shell of the driving motor 21 is fixed to the inner wall of the base 8 by bolts. A shock-absorbing rubber pad is also provided at the connection, which can effectively absorb the vibration generated when the motor is running, reduce noise and protect other components of the equipment. The output end of the driving motor 21 is fixedly connected to the rotating rod 1 22. The other end of the rotating rod 1 22 is connected to the inner wall of the base 8 through a bearing to ensure that the rotating rod 1 22 is flexible during rotation. To ensure smooth movement and reduce friction resistance, the base 8 is internally rotatably connected to the rotating rod 23, and the outer walls of the rotating rod 1 22 and the rotating rod 23 are provided with a flexible plate 24. The flexible plate 24 is made of wear-resistant rubber material and has good flexibility and wear resistance. A high-strength fiber reinforcement layer is also embedded in the rubber material, which can not only ensure that the flexible plate 24 is not easy to break during the reciprocating motion, but also effectively transmit power. The inner wall of the flexible plate 24 is slidably connected to the rotating rod 1 22 and the outer wall of the rotating rod 23. The flexible plate 24 is tightly connected to the rotating rod 1 22 and the rotating rod 2 23 by bolts, ensuring that there will be no slipping or falling off during the rotation process. The inner wall of the base 8 is provided with a slide groove 26, and the side wall of the flexible plate 24 is fixedly connected to the side wall of one end of the cleaning brush 25;

[0038] Specifically, when the grinding rod 11 is grinding the material, a large amount of debris will be generated due to friction. At this time, the negative pressure fan 20 inside the base 8 begins to play a key role. The negative pressure fan 20 starts to work to generate negative pressure, and the debris is sucked onto the surface of the filter plate 16 on the inner wall of the base 8. When the debris accumulates to a certain amount on the filter plate 16, the drive motor 21 inside the side of the base 8 is started, and the drive motor 21 drives the rotating rod 1 22 to rotate back and forth. The rotation of the rotating rod 1 22 also drives the rotating rod 2 23 to rotate through the flexible plate 24. As the rotating rod 1 22 and the rotating rod 2 23 rotate, the flexible plate 24 is prompted to rotate. The flexible plate 24 undergoes reciprocating displacement, and during the displacement process, one end of the flexible plate 24 connected to the cleaning brush 25 drives the cleaning brush 25 to move on the surface of the filter plate 16. The outer wall of the collection box 17 is tightly matched with the slide groove 19 on the side wall of the base 8. The handle 18 fixedly connected to the side wall of the collection box 17 is made of plastic or metal, and the surface is anti-slip treated, which is convenient for the staff to pull the collection box 17. The staff can pull the collection box 17 through the handle 18 to process the debris inside the collection box 17, thereby achieving the effect of efficiently cleaning the debris generated by grinding burrs, keeping the working area clean, and also facilitating the normal operation and maintenance of the equipment.

[0039] Working principle: When using this device, the material tray 3 is first transported by the conveyor table 2, and the material to be polished and deburred is sent to the side wall of the cabinet 1, and then the clamping head 7 on the mechanical arm 6 inside the cabinet 1 grabs the material to the top of the base 8, and then the polishing rod 11 polishes and deburrs the material. When a different polishing rod 11 needs to be replaced, the staff first rotates the threaded rotating block 13 toward the bottom of the threaded base 15. As the threaded rotating block 13 rotates and displaces, the rolling ball 14 inside the threaded base 15 gradually loses the lateral accumulated pressure and becomes able to slide. At this time, the staff can manually remove the polishing rod 11 and replace it with a new polishing rod 11. At this time, the new polishing rod 11 is inserted into the threaded base 15. When the ball groove 12 at the end of the polishing rod 11 is located at the position of the rolling ball 14, the staff rotates the threaded rotating block 13 in the opposite direction again. The displacement of the threaded rotating block 13 squeezes the rolling ball 14 to slide into the ball groove 12, thereby completing the replacement. The unlocking and locking of the grinding rod 11 achieves the effect of quickly and efficiently replacing the grinding rod 11. When the grinding rod 11 is working, a large amount of debris will be generated. At this time, the negative pressure fan 20 inside the base 8 starts to work to generate negative pressure, sucking the debris into the surface of the filter plate 16 on the inner wall of the base 8. When a certain amount is accumulated, the driving motor 21 inside the side of the base 8 starts to drive the rotating rod 1 22 to rotate reciprocatingly. The rotation of the rotating rod 1 22 also drives the rotating rod 23 to rotate through the flexible plate 24. As the rotating rod 1 22 and the rotating rod 2 23 rotate, the flexible plate 24 is displaced back and forth. The displacement of the flexible plate 24 drives the cleaning brush 25 on the surface of the filter plate 16 to start displacement, sweeping the debris into the drop hole 28 and falling into the collection box 17 through the drop hole 28. The staff can pull the collection box 17 by the handle 18 to process the debris inside the collection box 17, thereby achieving the effect of efficiently cleaning the debris generated by grinding burrs.
