Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing technology, and in particular to a burr removal device for cutting tool processing. Background Technology

[0002] Knives are among the oldest and most important tools in human history, closely intertwined with our daily lives and the development of civilization. From ancient stone knives used for cutting and hunting to modern knives of various shapes and functions, they have always played an indispensable role in human production and life.

[0003] Currently, most operators still use handheld devices for manual deburring of cutting tools. This method is not only inefficient and labor-intensive, but also significantly increases the burden on operators. Furthermore, the deburring process generates a large amount of metal dust, which, if not handled promptly and effectively, can harm the health of operators, thus reducing the practicality and safety of the entire process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned in the background section by providing a burr removal device for tool processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A burr removal device for cutting tool processing includes a circular work plate, a worktable fixedly connected to the upper surface of the circular work plate, a support frame fixedly connected to the rear of the upper surface of the worktable, a drive motor fixedly mounted on the upper surface of the support frame, and a grinding plate fixedly connected to the power output end of the drive motor.

[0007] A guide groove is provided in the middle of the upper surface of the workbench. Two moving blocks are slidably connected inside the guide groove. A limit frame is fixedly connected to the front of each of the two moving blocks. A threaded rod is threadedly connected to the upper surface of the right limit frame, and a movable rod is movably connected to the upper surface of the left limit frame. A pressure plate is movably mounted on the lower surface of the threaded rod via a rotating shaft. A second pressure plate is fixedly connected to the lower surface of the movable rod. A connecting plate is fixedly connected to the inner side of the first and second pressure plates. A push rod is fixedly connected to the left side of the left moving block.

[0008] Preferably, the upper surface of the circular working plate is provided with an annular guide groove, and the lower surface of the circular working plate is fixedly connected with a support column.

[0009] Preferably, a placement frame is fixedly connected to the lower surface of the circular working plate, and a second drive motor is fixedly installed on the upper surface of the placement frame. A drive rod is fixedly connected to the power output end of the second drive motor.

[0010] Preferably, a gear is fixedly connected to the upper surface of the drive rod, and a toothed ring is meshed with the outer surface of the gear, with the toothed ring located inside the annular guide groove.

[0011] Preferably, an annular plate is fixedly connected to the upper surface of the toothed ring, and a movable plate is fixedly connected to the upper surface of the annular plate.

[0012] Preferably, a vacuum cleaner is fixedly installed on the upper surface of the movable plate, a vacuum hose is fixedly connected to the output end of the vacuum cleaner, a vacuum sleeve is fixedly connected to the rear of the vacuum hose, and a vacuum head is fixedly installed inside the vacuum sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a push rod to slide a movable block within a guide groove, allowing adjustment of the position of the limiting frame to accommodate tools of different sizes. The threaded rod on the right limiting frame and the movable rod on the left limiting frame work together to securely fix the tool in place using pressure plates one and two. The threaded rod design also allows for easy adjustment of the height of pressure plate one to accommodate tools of varying thicknesses. The clamping process is simple and quick, reducing the operator's workload and improving work efficiency.

[0015] The second drive motor, through the transmission of a drive rod, gears, and a gear ring, drives the annular plate and movable plate to rotate, enabling the vacuum cleaner to move in a circular motion around the blade, comprehensively collecting the debris generated during the grinding process. The design of the vacuum hose and vacuum sleeve allows the vacuum head to be close to the blade, effectively removing debris, maintaining a clean working environment, and also protecting the health of the equipment and operators.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-4 A burr removal device for cutting tool processing includes a circular working plate 1, a worktable 2 fixedly connected to the upper surface of the circular working plate 1, a support frame 3 fixedly connected to the rear of the upper surface of the worktable 2, a drive motor 4 fixedly installed on the upper surface of the support frame 3, and a grinding plate 5 fixedly connected to the power output end of the drive motor 4.

[0025] A guide groove 6 is provided in the middle of the upper surface of the worktable 2. Two moving blocks 7 are slidably connected inside the guide groove 6. Limiting frames 8 are fixedly connected to the front of each of the two moving blocks 7. A threaded rod 9 is threadedly connected to the upper surface of the right limiting frame 8, and a movable rod 10 is movably connected to the upper surface of the left limiting frame 8. A pressure plate 11 is movably mounted on the lower surface of the threaded rod 9 via a rotating shaft. A pressure plate 12 is fixedly connected to the lower surface of the movable rod 10. A connecting plate 13 is fixedly connected to the inner side of the pressure plate 11 and the pressure plate 12. A push rod 14 is fixedly connected to the left side of the left moving block 7. The burr removal equipment for tool processing is based on the circular worktable 1, and the worktable 2 fixed above it provides an operating platform for tool processing. The support frame 3 behind the worktable 2 serves to fix the drive motor 4. When the drive motor 4 is started, its power output end will drive the grinding plate 5 to rotate at high speed. The rotating grinding plate 5 can contact the burrs on the tool surface and remove the burrs through friction cutting.

[0026] To ensure the tool's stable position during grinding, a guide groove 6 on the worktable 2 provides a sliding track for the two moving blocks 7. The limiting frame 8 connected to the front of the moving blocks 7 can be adjusted by pushing the moving blocks 7 with a push rod 14 to accommodate tools of different sizes. After the tool is placed between the two limiting frames 8, rotating the threaded rod 9 on the right limiting frame 8 will cause the threaded rod 9 to move downwards along the thread, thereby driving the pressure plate 11 to move downwards. Since the pressure plate 11 and the pressure plate 2 are connected by a connecting plate 13, and the pressure plate 212 is fixed to the movable rod 10 on the left limiting frame 8, the downward movement of the pressure plate 11 will pull the pressure plate 212 downwards synchronously. Finally, the two pressure plates together firmly fix the tool on the worktable 2, preventing the tool from shaking during grinding and affecting the machining accuracy.

[0027] In actual processing, the operator first adjusts the position of the moving block 7 and the limit frame 8 using the push rod 14, places the tool in, and fixes the tool by driving the pressure plate with the threaded rod 9. Then, the drive motor 4 is started to rotate the grinding plate 5, and the push rod 14 is slowly pushed to move the moving block 7 and the tool toward the grinding plate 5, so that the part of the tool that needs to be deburred comes into contact with the rotating grinding plate 5. The high-speed rotation of the grinding plate 5 cuts and grinds the burrs, thereby completing the burr removal operation.

[0028] The upper surface of the circular work plate 1 is provided with an annular guide groove 15, and the lower surface of the circular work plate 1 is fixedly connected with a support column 16. The annular guide groove 15 on the upper surface of the circular work plate 1 serves as the movement track for the movable parts in the equipment, which can limit the movement path of the movable parts and make them run smoothly only along the annular track. When collecting debris, the parts that need to move in a circle around the tool on the worktable 2 can achieve precise and non-offset rotation by relying on the annular guide groove 15, which ensures the relative position of the movable parts and the grinding area is stable. This not only avoids jamming or offset when the parts move, but also indirectly helps to improve the coordination efficiency of burr removal and dust collection, making the entire equipment run more smoothly.

[0029] A mounting bracket 17 is fixedly connected to the lower surface of the circular work plate 1, and a second drive motor 18 is fixedly mounted on the upper surface of the mounting bracket 17. A drive rod 19 is fixedly connected to the power output end of the second drive motor 18. In this burr removal equipment for tool processing, the core function of the mounting bracket 17 fixed to the lower surface of the circular work plate 1 is to provide a stable mounting carrier for the second drive motor 18. Because the second drive motor 18 generates power during operation, it needs a fixed support to prevent positional displacement. The mounting bracket 17, through its firm connection with the circular work plate 1, allows the second drive motor 18 to be stably mounted on it, ensuring that the motor will not shake during subsequent power output, thus laying the foundation for stable power transmission.

[0030] The second drive motor 18, mounted on the mounting frame 17, is the power source for the dust removal function of the equipment. When the equipment starts dust removal, the second drive motor 18 is started. The start of the second drive motor 18 will drive the drive rod 19 to rotate. The drive rod 19, as the link for power transmission, is closely connected at one end to the power output end of the second drive motor 18 and can rotate synchronously with the motor output end. In turn, the power generated by the second drive motor 18 is transmitted to the gear 20 of the equipment, providing power support for the structures in the equipment that need to move. This allows the equipment to smoothly carry out the supporting auxiliary operations while removing burrs, ensuring the continuity and efficiency of the overall operation of the equipment.

[0031] A gear 20 is fixedly connected to the upper surface of the drive rod 19. A gear ring 21 is meshed with the outer surface of the gear 20. The gear ring 21 is located inside the annular guide groove 15. The gear rings 21 are meshed with each other. The groove structure of the annular guide groove 15 limits and guides the gear ring 21, strictly restricting its movement trajectory and ensuring that it can only rotate smoothly along the annular path of the annular guide groove 15. This prevents the gear ring 21 from deviating, jamming, or falling off the track during movement, ensuring the stability and continuity of power transmission.

[0032] A ring plate 22 is fixedly connected to the upper surface of the toothed ring 21. A movable plate 23 is fixedly connected to the upper surface of the ring plate 22. A vacuum cleaner 24 is fixedly mounted on the upper surface of the movable plate 23. A vacuum hose 25 is fixedly connected to the output end of the vacuum cleaner 24. A vacuum sleeve 26 is fixedly connected to the rear of the vacuum hose 25. A vacuum head is fixedly mounted inside the vacuum sleeve 26. The vacuum cleaner 24 fixed on the movable plate 23 is the core component for debris collection. It moves around the tool on the worktable 2 as the movable plate 23 rotates. When the vacuum cleaner 24 is started, it transmits suction power to the vacuum head inside the vacuum sleeve 26 through the vacuum hose 25 connected to the output end. The vacuum hose 25 has a certain degree of flexibility and can flexibly adapt to the rotation of the movable plate 23 to ensure that the vacuum head can always be close to the tool grinding area to suck up the burrs and debris generated during the grinding process in time, and then transport them to the vacuum cleaner 24 for collection through the vacuum hose 25.

[0033] Currently, most operators still use handheld devices for manual deburring of cutting tools. This method is not only inefficient and labor-intensive, but also significantly increases the burden on operators. Furthermore, the deburring process generates a large amount of metal dust, which, if not handled promptly and effectively, can harm the health of operators, thus reducing the practicality and safety of the entire process.

[0034] When the operator uses this device, first place the tool to be deburred on the worktable 2, with the part of the tool to be deburred facing down towards the grinding plate 5. Ensure that both ends of the tool are aligned with the inner sides of the two limit frames 8 to avoid tool deviation affecting grinding accuracy. Rotate the threaded rod 9 on the right limit frame 8 clockwise. The threaded rod 9 moves down along the thread, causing the pressure plate 11 to move down synchronously. Since pressure plate 11 and pressure plate 12 are connected by connecting plate 13, when pressure plate 11 moves down, it will pull pressure plate 12 down synchronously along the left movable rod 10 until the two pressure plates are tightly pressed against the upper surface of the tool. Continue to rotate the threaded rod 9 until the tool is firmly fixed without any up-down or left-right wobbling. Turn on the control switch of drive motor 4. The power output end of drive motor 4 drives the grinding plate 5 to rotate at high speed. After the grinding plate 5 has stabilized, slowly loosen the temporary fixation of the moving block 7. Slowly push the moving block 7 through the push rod 14 to move the tool along the guide groove 6 towards the grinding plate 5, so that the part of the tool that needs to be deburred comes into contact with the rotating grinding plate 5. According to the distribution of the tool burrs, finely adjust the tool's moving speed and position through the push rod 14 to ensure that the grinding plate 5 evenly covers the tool burr area. For parts with thicker burrs, the moving speed can be appropriately slowed down to allow the grinding plate 5 to fully cut the burrs; for parts with thinner burrs, maintain a uniform moving speed to avoid over-grinding and damaging the tool body. Throughout the grinding process, the surface condition of the tool must be observed to ensure that burrs are completely removed and the tool surface is smooth.

[0035] Simultaneously with the start of the grinding mechanism, the switch of the vacuum cleaner 24 is turned on, creating negative pressure in the suction head inside the suction sleeve 26. Then, the control switch of the drive motor 18 is turned on, and the drive motor 18 drives the drive rod 19 to rotate via its power output end. The gear 20 at the top of the drive rod 19 rotates synchronously, meshing with the gear ring 21 and driving the gear ring 21 to move in a circular motion along the annular guide groove 15. As the gear ring 21 rotates, its top annular plate 22 and movable plate 23 rotate synchronously. The vacuum cleaner 24, suction hose 25, and suction sleeve 26 on the movable plate 23 also move in a circular motion around the worktable 2. The operator can manually adjust the angle of the suction sleeve 26 to ensure the suction head is always close to the contact area between the grinding plate 5 and the tool. This allows for timely suction of burrs and debris generated during grinding, which is then drawn into the dust collection bag inside the vacuum cleaner 24 via the suction hose 25. This prevents debris from flying and polluting the environment or affecting machining accuracy. After the tool burrs are completely removed, the drive motor 4 is turned off. Once the grinding plate 5 stops rotating, the threaded rod 9 is rotated counterclockwise, causing the pressure plates 11 and 12 to move upwards, loosening the fixation on the tool. The tool is then moved off the worktable 2 using the push rod 14.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
