DETAILED DESCRIPTION

[0024] 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.

[0025] Reference Figure 1-Figure 3The present invention provides an embodiment of a robot cutting device for machining, comprising a mechanical arm 1, a movable head 2 and a fixed-distance fine-adjustment component. The mechanical arm 1 serves as the support and movement basis of the entire device. The bottom of the mechanical arm 1 and the movable head 2 are both equipped with a motor 3. The top of the movable head 2 is connected to the fixed-distance fine-adjustment component, which can drive the cutting wheel 6 to rotate and cut. The angle can be fine-tuned under the action of the fixed-distance fine-adjustment component. The fixed-distance fine-adjustment component is arranged on the top of the movable head 2. The output end of the lower motor 3 is fixedly connected to a rotating seat 4. The outer side of the rotating seat 4 is fixedly connected to two limit plates 5 to limit the installation position of the cutting wheel 6. The outer side of the rotating seat 4 is provided with an easy-to-disassemble component for facilitating the disassembly and replacement of the cutting wheel 6; the easy-to-disassemble component includes a fixed block 7, which is fixedly connected to the outer side of the rotating seat 4. The outer side of the fixed block 7 is fixedly connected to two spring telescopic rods 8, which provide fixing force for the installation of the cutting wheel 6 and are convenient for retraction during disassembly. The outer side of the spring telescopic rod 8 is fixedly connected with a paddle 9, which is used to paddle the spring telescopic rod 8 to retract so as to disassemble the cutting wheel 6. Four support blocks 10 are provided on the outer side of the rotating seat 4, which engage with the inside of the cutting wheel 6 to provide support and positioning for the cutting wheel 6. An assembly groove 11 is provided on the outer side of the support block 10, and two sockets 12 are provided inside the cutting wheel 6. A mounting block 13 is provided on the outer side of the cutting wheel 6. The outer side of the mounting block 13 is fixedly connected with two plug rods 14, which are inserted into the sockets 12 and engage with the spring telescopic rod 8 work together to ensure that the cutting wheel 6 is firmly installed and can be pulled out when disassembled. Two slots 15 are provided on the inner side of the mounting block 13. The outer side of the support block 10 fits with the outer side of the rotating seat 4, wherein the outer sides of the two support blocks 10 fit with the outer sides of the two limit plates 5 respectively. The inner side of the cutting wheel 6 fits with the inner side of the assembly groove 11, the outer side of the insertion rod 14 is slidably connected with the inner side of the socket 12, the outer side of the support block 10 fits with the outer side of the mounting block 13, and one end of the spring telescopic rod 8 fits inside the slot 15.

[0026] Specifically, when the cutting wheel 6 needs to be replaced after prolonged use, a worker can gently manually move the two paddles 9. As the paddles 9 move, the spring-loaded telescopic rod 8 connected to it begins to retract. During this process, one end of the spring-loaded telescopic rod 8 gradually withdraws from the interior of the retaining slot 15. Next, the insertion rod 14 on the outside of the mounting block 13 is withdrawn from the interior of the receptacle 12, and the mounting block 13 is removed. At this point, the cutting wheel 6 and its four support blocks 10 can be smoothly removed from the outside of the rotating base 4. Subsequently, the four support blocks 10 are pushed toward the center. Due to the unique connection between the support blocks 10 and the cutting wheel 6, they will slide out of the central through-hole of the cutting wheel 6. This series of operations completes the removal of the cutting wheel 6. Compared to traditional bolt-on methods, this disassembly method eliminates the need for additional tools, making it more convenient and efficient, significantly saving time and labor costs.

[0027] Reference Figure 3-Figure 5 The outer side of the robotic arm 1 is fixedly connected to two telescopic columns 16. The fixed distance fine-tuning component includes a movable cylinder 17, the inner wall of which is connected to the connecting column 20 through a fixed ring 19, and cooperates with the movable head 2 and the teeth 18 to achieve angle fine-tuning. The outer side of the movable cylinder 17 is fixedly connected to one end of the two telescopic columns 16, the inner wall of the movable cylinder 17 is fixedly connected to a fixed ring 19, and the inner side of the fixed ring 19 is slidably connected to a connecting column 20. The bottom of the connecting column 20 is fixedly connected to the top of the movable head 2, and the top of the connecting column 20 is fixedly connected to the output end of the upper motor 3. Then, multiple teeth 18 are provided on the adjacent sides of the movable head 2 and the movable cylinder 17, and the angle is fine-tuned by meshing and staggering, and the single rotation angle can be controlled. Multiple teeth 18 on the upper and lower sides are meshed, and a reset spring 22 is provided on the outer sleeve of the connecting column 20 to provide elastic force when the angle is fine-tuned to reset the movable cylinder 17 and ensure that the teeth 18 are re-engaged. One end of the reset spring 22 is fixedly connected to the sliding ring 21, and the bottom of the sliding ring 21 is in contact with the top of the fixed ring 19. The other end of the reset spring 22 is fixedly connected to the top of the connecting column 20.

[0028] Specifically, when the cutting angle of the cutting wheel 6 needs to be fine-tuned, the movable head 2 can be rotated first. While rotating the movable head 2, the movable cylinder 17 is pushed to slide. In this way, the multiple teeth 18 on the adjacent sides of the movable head 2 and the movable cylinder 17 are disengaged. In this state, the movable head 2 can drive the cutting wheel 6 to rotate freely and quickly. In addition, the upper motor 3 can be started. When the upper motor 3 starts working, it drives the connecting column 20 to rotate. At a low speed, the multiple teeth 18 will gradually shift their positions. As the teeth 18 shift, the movable cylinder 17 will also move slightly. When the multiple teeth 18 are completely offset by one grid, the movable cylinder 17 will quickly reset under the elastic force of the reset spring 22. At this time, the multiple teeth 18 will re-engage. In this way, the cutting wheel 6 can rotate to a fixed angle. Moreover, the angle of a single rotation can be accurately controlled by setting the size of the teeth 18. This method does not require the aid of other tools for measurement and is more accurate and reliable than the subjective judgment of the staff. In actual working scenarios, it can greatly improve the accuracy of the cutting angle and ensure the quality and efficiency of the cutting work.

[0029] Working principle: When the cutting wheel 6 needs to be replaced after long-term use, the two paddles 9 can be toggled to shrink the spring telescopic rod 8, and one end of the spring telescopic rod 8 can be pulled out from the inside of the card slot 15, and then the insertion rod 14 is pulled out from the inside of the socket 12. After removing the mounting block 13, the cutting wheel 6 and the four support blocks 10 are removed from the outside of the rotating seat 4, and then the four rotating seats 4 are pushed toward the center and slide off the central through hole of the cutting wheel 6. In this way, the cutting wheel 6 is disassembled. Compared with traditional bolt fastening, other tools are eliminated during disassembly, which is more convenient.

[0030] In addition, when it is necessary to fine-tune the cutting angle of the cutting wheel 6, the movable head 2 can be rotated and the movable cylinder 17 can be pushed to slide to cancel the engagement between the multiple teeth 18, so that the movable head 2 can drive the cutting wheel 6 to rotate freely and quickly, and the upper motor 3 can be started to drive the connecting column 20 to rotate. At low speed, the multiple teeth 18 will gradually stagger their positions, and the movable cylinder 17 will also move slightly. When the multiple teeth 18 are completely staggered by one grid, the movable cylinder 17 will quickly reset under the elastic force of the reset spring 22, and the multiple teeth 18 will re-engage. The following can achieve rotation at a fixed angle. The angle of a single rotation can be controlled by setting the size of the teeth 18. No tool is needed to measure, which is more accurate than the subjective judgment of the staff.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
