It comes in various types and is suitable for deburring workpieces of different materials, shapes, and sizes, finding wide application in industries such as machinery manufacturing, electronics, automotive, and aerospace. The disc brush unit in the deburring mechanism is a core actuator, and its performance directly determines the precision, efficiency, and surface quality of the deburring process.

[0003] Currently, some deburring mechanisms with rotation and revolution have disc brush units that use fixed connections or complex mechanical connections. The disassembly and replacement of the disc brush head requires the use of special tools and cumbersome mechanical disassembly operations.

[0062] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0063] This embodiment discloses a deburring mechanism based on rotation and revolution, such as... Figure 1As shown, in this embodiment, the rotation-revolution deburring mechanism includes a brush unit 1, a rotation unit 2, a revolution unit 3, and a lifting unit 4. Three brush units 1 are provided, each including a brush shaft 11 and a brush head 12 connected magnetically from top to bottom. The magnetically detachable connection between the brush shaft 11 and brush head 12 in the rotation-revolution deburring mechanism enables rapid disassembly and replacement of the brush head 12 without the need for complex tools or cumbersome mechanical disassembly operations. This shortens the replacement time after brush head 12 wear and reduces equipment downtime, thus improving overall deburring efficiency. Simultaneously, the magnetic connection ensures the coaxiality of the brush head 12 and brush shaft 11 during disassembly and assembly, preventing assembly deviations from affecting deburring accuracy. It also reduces the difficulty of manual operation. Furthermore, the stability of the magnetic connection ensures that the brush head 12 remains stable during rotation and revolution, preventing it from falling off due to high-speed operation or vibration, further guaranteeing the safety and stability of the deburring operation. The output end of the disc brush unit 1 is connected to the output end of the rotation unit 2. The rotation unit 2 is used to drive the disc brush head 12 to rotate around the disc brush shaft 11. The output end of the revolution unit 3 is connected to the disc brush unit 1. The revolution unit 3 is used to drive the disc brush unit 1 to rotate around the revolution shaft (i.e., the main shaft mentioned below). The lifting unit 4 is set on one side of the disc brush unit 1. The lifting unit 4 is connected to the revolution unit 3. The lifting unit 4 is detachably connected to the rotation unit 2 and rotatably connected to the revolution unit 3. The lifting unit 4 is used to drive the disc brush unit 1, the rotation unit 2 and the revolution unit 3 to move in the vertical direction. The coordinated action between the disc brush unit 1, the rotation unit 2 and the revolution unit 3 and the lifting unit 4 enables the disc brush head 12 to rotate around its own disc brush shaft 11 to generate the core deburring cutting action, while also revolving around the revolution shaft with the disc brush unit 1 as a whole. Furthermore, it can move flexibly in the vertical direction under the drive of the lifting unit 4, thereby performing all-round and multi-angle cleaning operations on burrs at different positions and heights on the workpiece surface.

[0064] Specifically, such as Figure 1As shown, in this embodiment, the disc brush unit 1 also includes a magnetic adsorption seat 13 and a magnetic connector 14. The magnetic adsorption seat 13 is connected to the bottom end of the disc brush shaft 11, and the magnetic connector 14 is embedded in the disc brush head 12 and magnetically connected to the magnetic adsorption seat 13. This optimizes the magnetic detachable connection structure between the disc brush shaft 11 and the disc brush head 12. Through the precise cooperation between the magnetic adsorption seat 13 and the embedded magnetic connector 14, the coaxiality of the disc brush head 12 and the disc brush shaft 11 is more stably guaranteed, effectively avoiding the impact of assembly deviation on deburring accuracy. At the same time, it reduces the difficulty of manual operation. Moreover, this structured magnetic connection method can further enhance the stability of the disc brush head 12 during rotation and revolution, preventing it from falling off due to high-speed operation or vibration. This provides more comprehensive protection for the safety and stability of deburring operations, and provides more reliable structural support for the collaborative work of the disc brush unit 1 with the rotation unit 2, revolution unit 3, and lifting unit 4, helping to achieve all-round and multi-angle cleaning of burrs at different positions and heights on the workpiece surface.

[0065] Specifically, such as Figure 1 As shown, in this embodiment, the magnetic adsorption base 13 includes a quick-mount fixing plate 131 for the brush disc and a quick-mount bolt 132 for the brush disc. The quick-mount fixing plate 131 is installed at the bottom end of the brush disc shaft 11, and the top end of the quick-mount bolt 132 is connected to the quick-mount fixing plate 131. The quick-mount bolt 132 can pass through the brush disc head 12. The magnetic connector 14 is connected to the quick-mount bolt 132, making the engagement between the magnetic connector 14 and the magnetic adsorption base 13 more precise and rapid. During the installation of the brush disc head 12, the quick-mount bolt 132 can guide the brush disc head 12 to accurately align with the brush disc shaft 11. At the same time, the limiting function of the fixing plate prevents the brush disc head 12 from shifting position during assembly, ensuring that the brush disc head 12 and the brush disc shaft 11 always maintain the same height. The axial alignment fundamentally avoids the impact of assembly deviations on deburring accuracy. The disassembly and assembly of the disc brush can be achieved simply by removing and installing the magnetic connector 14 and the disc brush itself, simplifying the replacement process of the disc brush head 12. Manual operation requires no complex tools; the replacement of the disc brush head 12 can be completed with simple installation or disassembly actions, significantly shortening the replacement time after wear and tear, effectively reducing equipment downtime, and significantly improving overall work efficiency. Furthermore, the magnetic adsorption seat 13, through the limiting position of the fixed plate and the structural support of the disc brush quick-release bolts 132, combined with the magnetic connection, forms a double guarantee during the high-speed rotation and revolution of the disc brush unit 1, preventing the disc brush head 12 from loosening or falling off due to high-speed operation or vibration, further enhancing connection stability and ensuring operational safety.

[0066] Preferably, such as Figure 1As shown, in this embodiment, the disc brush unit 1 also includes a disc brush mounting cover 15. The disc brush mounting cover 15 is located at the bottom of the revolution unit 3 and is located on the outer periphery of the disc brush shaft 11. It is used to protect the disc brush shaft 11 exposed outside the revolution unit 3, preventing it from being bumped or scratched by external debris during equipment operation, or from being affected by dust, debris and other contaminants, which would affect its rotational accuracy and service life. It can also indirectly ensure the stability of the magnetic connection between the disc brush shaft 11 and the disc brush head 12, prevent external interference from causing coaxiality deviation between the two, thereby ensuring the accuracy of the rotation and revolution of the disc brush head 12, reducing the problem of reduced deburring accuracy caused by damage or contamination of the disc brush shaft 11, reducing equipment maintenance costs, and further ensuring the overall stability and continuity of the rotation and revolution deburring mechanism.

[0067] Specifically, such as Figures 1-3 As shown, in this embodiment, the rotation unit 2 includes a rotation motor 21, a main shaft 22, a rotation housing 23, a main gear 24, and a secondary gear 25. The main shaft 22 is connected to the rotation motor 21, which drives the main shaft 22 to rotate. The rotation housing 23 is fitted around at least part of the outer circumference of the main shaft 22 and is connected to the bottom of the rotation motor 21. The main gear 24 is fixedly fitted around the bottom outer circumference of the main shaft 22, which drives the main gear 24 to rotate. The secondary gear 25 is located circumferentially outside the main gear 24, and the main gear 24 and secondary gear 25 are on the same plane. Located at the top of the brush shaft 11, the main gear 24 meshes with the secondary gear 25, thereby driving the secondary gear 25 and the brush shaft 11 to rotate. Ultimately, the brush head 12 rotates around the brush shaft 11 to generate the core deburring action. The gear meshing ensures the stability and accuracy of the transmission, ensuring that the brush head 12 rotates at a uniform speed, improving the deburring accuracy and consistency. It can also provide stable power with the help of the self-rotating motor 21 to meet the speed requirements of the brush head 12 for different deburring operations. At the same time, the self-rotating housing 23 protects the main shaft 22 and other components, reduces the interference of external factors on the transmission components, and extends the service life of the self-rotating unit 2.

[0068] Furthermore, in this embodiment, the main gear 24 has 38 teeth and a helix angle of 20 degrees, the secondary gear 25 has 35 teeth and a helix angle of 20 degrees, and the center distance of the secondary gear 25 is 90-100 mm. The main gear 24 and the secondary gear 25 are designed with opposite helix directions, which can reduce bearing load and counteract axial force. Specifically, in this embodiment, the center distance of the secondary gear 25 is 95 mm. In other embodiments, the center distance of the secondary gear 25 can also be 93 mm, 94 mm, 96 mm, or 97 mm, etc. In other embodiments, the main gear 24 can have 35, 33, 37, 39, or 40 teeth, etc., and the secondary gear 25 can have 32, 33, 34, 36, 37, or 38 teeth, etc. Both the main gear 24 and the secondary gear 25 can also have rotation angles of 17 degrees, 18 degrees, 19 degrees, 21 degrees, 22 degrees, or 23 degrees.

[0069] Preferably, such as Figures 1-3 As shown, in this embodiment, the self-rotating unit 2 also includes an oil guide cover 26 and an oil guide impeller 27. The oil guide cover 26 is disposed on the outer periphery of the bottom end of the main shaft 22 and connected to the main shaft 22. The oil guide cover 26 is used for oil storage and oil guidance. The oil guide impeller 27 is installed on the circumferential outer wall of the bottom end of the main shaft 22 and is disposed inside the oil guide cover 26. It is used to agitate the lubricating oil inside the oil guide cover 26. Through its own oil storage and oil guidance functions, the oil guide cover 26 provides a stable lubricating oil storage space and guiding path for the gear meshing area and the bottom of the main shaft 22. The oil guide impeller 27, which rotates synchronously with the main shaft 22, agitates the lubricating oil inside the oil guide cover 26, which can evenly disperse and deliver the lubricating oil to the meshing surfaces of the main gear 24 and the secondary gear 25, the fitting clearance between the main shaft 22 and the self-rotating housing 23, and other key friction surfaces. The lubrication system eliminates the need for frequent manual lubrication, achieving automated lubrication, reducing manual maintenance costs and equipment downtime, ensuring the continuity of deburring operations, and improving overall work efficiency. Uniform lubrication effectively reduces frictional losses during the meshing of the main and auxiliary gears 25 and the operation of the main shaft 22, slowing down component wear, extending the service life of the transmission components of the self-rotating unit 2, and preventing gear jamming and main shaft 22 jamming caused by overheating. This ensures the stability and accuracy of gear transmission, thereby maintaining the uniform and controllable rotation speed of the brush head 12, ensuring that deburring accuracy is not affected by transmission failures. The oil guide cover 26 also prevents contamination caused by lubricating oil overflow and avoids external dust and debris entering the lubrication area to contaminate the lubricating oil, ensuring the durability of the lubrication effect.

[0070] Specifically, such as Figures 1-3As shown, in this embodiment, the revolution unit 3 includes a revolution motor 31, a revolution housing 32, and a synchronizing element 33. The revolution housing 32 is sleeved on at least part of the rotation unit 2, and the housing of the revolution unit 3 is rotatably connected to the rotation unit 2. The disc brush unit 1 is inserted into the bottom of the revolution housing 32 and is rotatably connected to the revolution housing 32. The synchronizing element 33 is connected to the output end of the revolution motor 31 and the revolution housing 32. The synchronizing element 33 is used to drive the revolution housing 32 to rotate. By connecting the output end of the revolution motor 31 and the revolution housing 32 with the synchronizing element 33, the rotation unit 32 can be driven on at least part of the rotation unit 2. The rotating outer shell 32, which is rotatably connected to the rotating unit 2 and has the bottom of the disc brush unit 1 inserted and rotatably connected to it, rotates, thereby driving the disc brush unit 1 to rotate around the revolution axis. This allows the disc brush unit 1 to rotate to remove burrs while simultaneously revolving around the revolution axis. In conjunction with the rotating unit 2 and the lifting unit 4, the working coverage of the disc brush head 12 can be greatly expanded, allowing it to more efficiently clean burrs in different areas of the workpiece surface. At the same time, the enveloping design of the rotating outer shell 32 on the rotating unit 2 can provide a certain degree of protection for the internal components and reduce the interference of impurities on the components during operation.

[0071] Preferably, such as Figures 1-3 As shown, in this embodiment, the synchronizing element 33 is a chain and sprocket structure 332. The chain and sprocket structure 332 includes two meshing double-row chains 331 and two sprockets 332. One of the two sprockets 332 is located on the outer periphery of the output end of the revolution motor 31 and is connected to the revolution motor 31. The other of the two sprockets 332 is located on the outer periphery of the input end of the revolution housing 32 and is connected to the revolution housing 32. The double-row chains 331 are simultaneously sleeved on the two sprockets 332 and mesh with the two sprockets 332, which can stably transmit the power of the revolution motor 31 to the revolution housing 32, thereby driving the revolution housing 32 and the disk brush unit 1 connected thereto to rotate precisely around the revolution axis. The meshing transmission of the double-row chain 331 and sprocket 332 has high transmission efficiency and transmission ratio accuracy, which can ensure the efficient and stable transmission of power of the revolution motor 31, making the revolution of the disc brush unit 1 more stable and reliable. At the same time, the chain and sprocket 332 have strong load-bearing capacity and can adapt to the load requirements of the disc brush unit 1 during revolution. Furthermore, the double-row chain 331 design can further improve the stability and impact resistance of the transmission, reduce vibration and noise during the transmission process, reduce the risk of equipment failure caused by transmission problems, reduce maintenance costs, facilitate later maintenance and replacement, and ensure the coordinated operation of revolution, rotation and lifting actions, thereby improving the overall precision and efficiency of deburring operation.

[0072] Preferably, such as Figures 1-3As shown, in this embodiment, the double-row chain 331 is a heavy-duty roller chain. Compared to ordinary chains, heavy-duty roller chains have thicker chain plates, stronger pins, and a larger load-bearing cross-section. They can easily withstand the impact loads and continuous tension generated during the deburring operation of the disc brush unit 1, effectively preventing chain deformation and breakage due to excessive load. This significantly extends the chain's service life and reduces equipment downtime for maintenance. Simultaneously, its roller structure design reduces the friction coefficient when the chain and sprocket 332 mesh, reducing wear and energy loss during transmission, ensuring transmission efficiency and accuracy. Even under long-term high-speed, high-load operating conditions, it maintains stable transmission performance, ensuring precise coordination of revolution, rotation, and lifting movements. This further guarantees the continuity, stability, and safety of the deburring operation, improving the overall equipment's operational reliability and service life. In other embodiments, the double-row chain 331 can also be a stainless steel double-row chain or a silent double-row chain, etc.

[0073] Optionally, in this embodiment, the transmission ratio of the two sprockets 332 is 17:7. Specifically, in this embodiment, the two sprockets 332 have 51 teeth and 21 teeth, respectively. In other embodiments, the sprocket 332 with 51 teeth in this embodiment can also have 49 teeth, 50 teeth, 52 teeth, or 53 teeth, etc., and the sprocket 332 with 21 teeth in this embodiment can also have 19 teeth, 20 teeth, 22 teeth, or 23 teeth, etc.

[0074] Preferably, in this embodiment, the heavy-duty roller chain pitch is 12.7 mm, and the pretension is 1.5-2% of the chain breaking force. This prevents the chain from skipping teeth or slipping during high-speed transmission due to slack, while also preventing excessive pretension from causing a surge in meshing stress between the chain and sprocket 332. This prevents premature wear or fatigue fracture of the chain plates and pins, balancing transmission stability and component lifespan, and ensuring the continuous reliability of power transmission in the revolution unit 3. In other embodiments, the heavy-duty roller chain pitch can also be 12.5 mm, 12.6 mm, 12.8 mm, 12.9 mm, or 13.0 mm, etc.

[0075] Specifically, such as Figures 1-4As shown, in this embodiment, the lifting unit 4 includes a first housing 41, a drive assembly 42, a transmission assembly 43, and a moving assembly 44. The drive assembly 42 is disposed inside the first housing 41 and is drive-connected to the transmission assembly 43. The moving assembly 44 is drive-connected to the transmission assembly 43 and is detachably connected to the rotation unit 2 and rotatably connected to the revolution unit 3. The transmission assembly 43 converts the power provided by the drive assembly 42 into a force that can drive the moving assembly 44 to move vertically. The lifting unit 4 can drive the brush unit 1, the rotation unit 2, and the revolution unit 3 to move vertically. The flexible movement of the brush head 12, combined with the rotation and revolution of the brush unit 1, allows the brush head 12 to precisely target burrs at different heights on the workpiece surface. The rotation and revolution deburring mechanism cleans burrs at different heights and positions on the workpiece surface from all angles, improving the comprehensiveness and precision of the deburring operation. The drive component 42 and transmission component 43, located within the first housing 41, protect the internal components, reduce external interference, and ensure the stability of the lifting action. The detachable connection between the moving component 44 and the rotation unit 2 also facilitates the maintenance and replacement of subsequent components, improving the overall operational reliability and service life of the equipment.

[0076] Preferably, such as Figures 1-4 As shown, in this embodiment, the drive assembly 42 includes a servo motor 421 and a synchronous pulley 422. The servo motor 421 is disposed inside the first housing 41. The driving pulley of the synchronous pulley 422 is connected to the output end of the servo motor 421, and the driven pulley of the synchronous pulley 422 is connected to the transmission assembly 43. The servo motor 421 provides power and drives the driven pulley through the driving pulley of the synchronous pulley 422, thereby driving the transmission assembly 43 to operate. This enables the lifting unit 4 to provide stable and precise power output, ensuring that the moving assembly 44 drives the brush unit 1 and other components to achieve precise vertical movement control. The synchronous pulley 422 has high transmission efficiency, smooth transmission, and low noise, which can reduce energy loss during power transmission. It also has buffering and vibration absorption capabilities, which can reduce the impact of vibration of the servo motor 421 during operation on the entire lifting unit 4 and the deburring mechanism, ensuring transmission accuracy and stability. Furthermore, it has a simple structure, is easy to maintain, and has a long service life, providing stable power transmission guarantee for the reliable operation of the lifting unit 4, thereby ensuring the accuracy and consistency of the vertical movement of the brush head 12.

[0077] Preferably, such as Figures 1-4As shown, in this embodiment, the transmission component 43 is a ball screw lifting structure. The input end of the ball screw lifting structure is connected to the drive component 42, and the output end of the ball screw lifting structure is connected to the moving component 44. The ball screw lifting structure accurately converts the power of the drive component 42 into a force that drives the moving component 44 to move stably vertically, thereby driving the brush unit 1, the rotation unit 2, and the revolution unit 3 to achieve precise vertical position adjustment. The ball screw lifting structure has the characteristics of high precision and low friction, which can improve the positional accuracy and motion stability of the lifting action of the moving component 44, avoid misalignment between the brush head 12 and the workpiece burr position due to lifting deviation, and ensure the deburring accuracy.

[0078] Preferably, such as Figures 1-4 As shown, in this embodiment, the moving component 44 includes a slide rail 441 and a first connector 442. The slide rail 441 is disposed on the side of the first housing 41 facing the rotating unit 2 and extends vertically. The first connector 442 is slidably connected to the slide rail 441. One end of the first connector 442 in the horizontal direction is detachably connected to the rotating unit 2 and rotatably connected to the revolution unit 3. The other end of the first connector 442 in the horizontal direction is drively connected to the transmission component 43. The slide rail 441, which extends vertically and is fixed on the first housing 41, provides a stable vertical guide path for the first connector 442, ensuring that the first connector 442 drives the rotating unit 2, the revolution unit 3, and the brush unit 1 in a vertical direction. The device does not deviate during linear movement, ensuring the accuracy of lifting and lowering actions. It also efficiently receives the power transmitted by the transmission component 43 and converts it into stable vertical movement through a sliding connection between one end of the first connecting piece 442 and the slide rail 441, and a transmission connection between the other end and the transmission component 43. At the same time, the first connecting piece 442 is detachably connected to the self-rotating unit 2 and rotatedly connected to the revolution unit 3 along the horizontal direction. This facilitates the disassembly and maintenance of the self-rotating unit 2 without affecting the independent rotation of the revolution unit 3 around the revolution axis. This achieves non-interference and efficient coordination between lifting and lowering actions and self-rotation and revolution actions, making the power transmission of the moving component 44 more stable and the movement trajectory more accurate. This helps the disc brush unit 1 to accurately adapt to the burr cleaning needs of workpieces at different heights.

[0079] Preferably, such as Figure 1As shown, in this embodiment, the self-rotation and revolution deburring mechanism also includes a first bearing 5. The outer ring of the first bearing 5 is connected to the first connecting member 442, and the inner ring of the first bearing 5 is sleeved outside the revolution shell 32, realizing the independent rotation of the revolution shell 32 within the first connecting member 442. This ensures that the revolution unit 3 drives the disc brush unit 1 to rotate around the revolution axis without interference from the first connecting member 442, ensuring the smoothness and stability of the disc brush unit 1 during revolution, reducing energy loss and component wear caused by friction, enhancing the motion coordination of the entire deburring mechanism, and enabling the disc brush unit 1 to more accurately conform to the surface of the part to be deburred during the combined motion of self-rotation and revolution.

[0080] Optionally, such as Figure 1 As shown, in this embodiment, two first bearings 5 ​​are provided, arranged at intervals along the vertical direction. This provides more stable support and positioning for the orbital housing 32 in the vertical direction, ensuring that the orbital housing 32 reduces swaying and offset when driving the brush unit 1 to rotate around the orbital axis, and maintains a stable rotation trajectory. In other embodiments, one, three, or four first bearings 5 ​​may also be provided.

[0081] Preferably, such as Figures 1-3 As shown, in this embodiment, the self-rotation and revolution deburring mechanism also includes a second bearing 6. The outer ring of the second bearing 6 is connected to the inner wall of the revolution housing 32, and the inner ring of the second bearing 6 is sleeved on the outside of the main shaft 22 and connected to the main shaft 22, so as to realize the flexible rotational connection between the revolution housing 32 and the main shaft 22. When the revolution motor 31 drives the revolution housing 32 to rotate or the self-rotation motor 21 drives the main shaft 22 to rotate, the revolution housing 32 and the main shaft 22 can maintain a relatively independent and stable motion relationship, avoid direct friction between the two, reduce mechanical wear, and enhance the motion coordination of the entire deburring mechanism during the combined motion of self-rotation and revolution of the disc brush unit 1.

[0082] Optionally, such as Figures 1-3 As shown, in this embodiment, two second bearings 6 are provided, arranged at intervals along the extension direction of the main shaft 22. This enables multi-point support for the connection structure between the orbiting housing 32 and the main shaft 22, effectively dispersing the radial and axial forces generated during orbital rotation. This allows the orbiting housing 32 to maintain a more stable posture when rotating around the main shaft 22, avoiding swaying, offset, or other issues. In other embodiments, one, three, or four second bearings 6 may also be provided.

[0083] Preferably, such as Figure 1As shown, in this embodiment, the self-rotation and revolution deburring mechanism also includes a third bearing 7. The outer ring of the third bearing 7 is connected to the inner wall of the bottom of the revolution housing 32. The inner ring of the third bearing 7 is sleeved on the outside of the brush shaft 11 below the auxiliary gear 25 and connected to the brush shaft 11. This ensures that while the brush unit 1 rotates around the revolution axis with the revolution housing 32 (i.e., revolution), the brush shaft 11 itself can also rotate stably. This avoids mutual interference between revolution and rotation, reduces friction and wear during rotation, enhances the overall stability and reliability of the mechanism, ensures the accuracy of the composite motion trajectory of the brush unit 1, thereby improving the quality and efficiency of deburring operations and extending the service life of the deburring mechanism.

[0084] Optionally, such as Figure 1 As shown, in this embodiment, two third bearings 7 are provided on each brush shaft 11. The two third bearings 7 are arranged at intervals along the axial direction of the brush shaft 11, which can effectively distribute the radial and axial loads generated by the brush unit 1 during its rotation and revolution, enhance the support stability of the brush shaft 11, and avoid problems such as eccentricity and shaking of the brush shaft 11 due to uneven force, so that the brush head 12 can maintain a precise movement trajectory during operation. In other embodiments, one, three, or four third bearings 77 may also be provided.

[0085] In summary, the self-rotation and revolution deburring mechanism disclosed in this embodiment uses a 51-tooth double-row sprocket 332 and a 21-tooth double-row sprocket 332 to drive the disc brush box to revolve via a double-row chain 331. Combined with a magnetic quick-release disc brush, the brush replacement time is shortened to <3 seconds, the tool switching efficiency is increased by 98%, and the burr removal rate is increased to 96%.

[0086] This embodiment also discloses a deburring device. In this embodiment, the deburring device includes a carrying mechanism and at least one rotating and revolving deburring mechanism arranged at intervals along the extension direction of the carrying mechanism. The part to be deburred is placed on the carrying mechanism, and at least one rotating and revolving deburring mechanism is located directly above the carrying mechanism. The deburring device conveys the part to be deburred through the carrying mechanism, and the rotating and revolving deburring mechanism arranged at intervals grinds and cleans it during its journey. It can complete multi-station deburring at one time, realize continuous automated processing, efficiently cover the surface of the part to be deburred, avoid repeated clamping, reduce manual intervention, improve production efficiency and consistency, and reduce labor intensity and cost. It is especially suitable for batch processing of precision parts.
