Description

Technical Field

[0001] This invention relates to the field of gear rotary surface grinding technology, and in particular to a deburring equipment for the rotary surface of cylindrical gears. Background Technology

[0002] Cylindrical gears are the core components of mechanical transmission. Their manufacturing precision directly affects transmission efficiency and service life. However, after processing, burrs will be generated on them. Burr residue will aggravate meshing impact, increase noise, accelerate tooth surface wear, and in severe cases, even lead to gear failure. With the increasing demand for lightweight design, gear end faces are often equipped with annular grooves (oil reservoirs, tool relief grooves) and multiple weight reduction holes. These structures significantly increase the difficulty of deburring.

[0003] A search revealed that Chinese patent document CN120480698A discloses an internal hole grinding device for manufacturing planetary gears in wind turbine gearboxes. The device includes a housing and a grinding rod installed inside the housing. An installation component is located at the upper end of the housing's interior, and a clamping component is located at the upper end of the installation component. A detection component is located on one side of the clamping component. The installation component can be used to install the clamping and detection components, and can also adjust their position within the housing. This invention provides an internal hole grinding device for manufacturing planetary gears in wind turbine gearboxes. It includes a clamping component and a detection component, which can detect the flatness of the end face of each gear and check for pits, protrusions, deformation, and horizontality of the grinding rod before each processing step. This ensures the perpendicularity of the end face to the internal hole, preventing over-grinding or under-grinding. Furthermore, it reduces coolant consumption and saves installation space.

[0004] Although the aforementioned grinding equipment for manufacturing planetary gears in wind turbine gearboxes can automatically detect the deformation and end face flatness of the grinding rod before grinding, it still has the following problems: This equipment focuses only on grinding the inner hole and cannot deburr the annular groove and weight reduction hole on the gear end face; the end face chamfering cutter has a fixed angle and cannot perform variable angle grinding for different tooth edges or groove sidewalls, resulting in incomplete burr removal in complex structures and making it difficult to meet the comprehensive deburring requirements of modern lightweight gears. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a deburring device for the rotating surface of cylindrical gears, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A deburring device for the rotating surface of a cylindrical gear includes a worktable and a workpiece. A processing plate is mounted on the worktable via a telescopic cylinder. The device also includes a self-clamping assembly for automatically straightening and clamping the workpiece on the worktable. The self-clamping assembly includes a motor fixedly mounted on the bottom of the worktable; an end-face processing assembly for deburring annular grooves on the end face of the workpiece, including a motor fixedly mounted on the processing plate. The output end of the motor is connected to a rotating disk rotatably connected to the processing plate via a reducer. An inner ring is fixedly mounted on the bottom of the rotating disk. Multiple flexible processing components are fitted between the rotating disk and the inner ring, automatically changing the deburring angle of the annular grooves on the end face of the workpiece during processing; and a hole processing assembly for deburring weight-reducing holes on the workpiece. The hole processing assembly includes a mounting ring rotatably connected to the inner ring, with multiple round rods rotatably mounted on the mounting ring. Each round rod has a fixed rod fixedly mounted on its bottom.

[0007] Furthermore, a drive rod is fixedly connected to the output end of the motor, and a hollow rod is mounted on the drive rod via a damping bearing. A bevel gear is fixedly mounted on the top of the hollow rod. Multiple lead screws are rotatably mounted inside the worktable, and each lead screw is fixedly mounted with a bevel gear that meshes with the bevel gear. Multiple sliding grooves are provided on the worktable, and a sliding rod that is threadedly connected to the corresponding lead screw is slidably mounted in each groove. A mounting block is fixedly mounted on the top of each sliding rod, and a clamping block is mounted on each mounting block via a connecting mechanism.

[0008] Furthermore, a grinding disc is fixedly installed on the top of the drive rod, and the connecting mechanism consists of a connecting block, a connecting groove, a spring, a guide block, and a three-way groove. The connecting block is fixedly installed on the clamping block, the connecting groove is opened on the mounting block, the spring is installed between the connecting block and the connecting groove, the guide block is fixedly installed on the side wall of the connecting block, and the three-way groove is opened on the side wall of the connecting groove, and the three-way groove cooperates with the guide block.

[0009] Furthermore, the flexible processing component comprises a moving rod, a fixed block, a grinding head, a rotating rod, a fixed disc, a moving groove, a telescopic groove, and a telescopic rod. The rotating disc and the bottom of the inner ring are both provided with moving grooves. The moving rod is slidably installed in the moving groove. The fixed block is installed at the bottom of the moving rod. The rotating rod is rotatably installed on the fixed block. The grinding head is fixedly installed on the rotating rod. Fixed discs are fixedly installed at both ends of the rotating rod, and torsion springs are installed between the two fixed discs and the fixed block. The telescopic groove is opened on the side wall of the moving groove. The telescopic rod is slidably installed in the telescopic groove, and the telescopic rod and the moving rod are wedge-shaped.

[0010] Furthermore, the processing plate has a groove, and multiple screws are rotatably installed on both the rotating disk and the inner ring. Each screw is threadedly connected to a corresponding telescopic rod. A chain drive structure is installed between every two corresponding screws. A fixed gear is fixedly installed on the top of each screw located on the inner ring. Multiple arc-shaped racks that cooperate with the fixed gears are fixedly installed on the inner wall of the groove.

[0011] Furthermore, multiple grinding blocks are fixedly installed on the side wall of each of the fixed rods, a fixed gear ring is fixedly installed on the top of each of the round rods, and a drive gear ring that meshes with the multiple fixed gear rings is fixedly installed on the side wall of the inner ring.

[0012] Furthermore, a collection cavity is provided inside the fixing rod, and a through hole communicating with the collection cavity is provided on the side wall of the fixing rod, and the through hole is located at the lower end of the grinding block.

[0013] Furthermore, a connecting ring that communicates with the collection chamber is rotatably sealed on the side wall of the fixing rod, and a connecting nozzle is fixedly connected to the connecting ring. A filter screen is fixedly installed inside the collection chamber, and a sealing cap is threadedly installed at the bottom of the collection chamber.

[0014] The beneficial effects are as follows: 1. Through the design of flexible processing components, the grinding head can perform radial scanning while revolving during the processing, and automatically deflect when the grinding head contacts the side wall of the annular groove, always fitting the groove wall at the optimal angle. Regardless of whether the annular groove is rectangular, trapezoidal or other irregular contours, the grinding head can fit tightly against the bottom and side wall of the groove, effectively removing burrs in complex structures and avoiding the problem of fixed-angle tools not being able to reach corners or excessive wear on the tooth surface.

[0015] 2. Through the cooperation of damping bearings, three-way grooves and guide blocks, during the movement of the clamping blocks toward the center, the flexible buffer of the spring and the sliding within the groove of the guide block allow the clamping blocks to automatically adjust their posture according to the outer diameter of the gear. When the gear is slightly misaligned, the clamping blocks compress the spring under radial force and generate circumferential oscillation. Combined with the rotation of the grinding disc, the gear automatically rotates and centers. Finally, all clamping blocks return to their positions synchronously to achieve precise centering. No manual centering is required, avoiding rigid impact damage to the tooth surface and significantly improving clamping efficiency and positioning accuracy.

[0016] 3. By combining the collection chamber with the through hole, metal chips generated during grinding can be collected, avoiding secondary scratches caused by chip residue in the hole, keeping the working environment clean, reducing subsequent cleaning processes, and improving processing quality and efficiency.

[0017] In summary, this invention achieves rapid and precise gear clamping, avoiding the tediousness and errors of manual alignment. Simultaneously, it allows the grinding head to synchronously scan radially and automatically adjust its angle during revolution, effectively solving the deburring problem of complex annular groove contours. Furthermore, it can simultaneously remove debris while grinding weight-reducing holes, preventing secondary contamination. This enables gears to undergo comprehensive deburring of the end face, annular groove, and weight-reducing holes in a single clamping operation, significantly improving processing efficiency and quality, and providing reliable technical support for the precision manufacturing of modern lightweight gears.

[0020] Reference Figures 1-6 A deburring machine for the rotating surface of a cylindrical gear includes a worktable 1 and a workpiece 2 (cylindrical gear) to be processed. A processing plate 4 is mounted on the worktable 1 via a telescopic cylinder 3. The telescopic cylinder 3 can drive the processing plate 4 to move up and down to adapt to gears of different heights and control the processing feed. The machine also includes a self-clamping assembly, an end face processing assembly, and a hole processing assembly. The three work together to complete the grinding and deburring of various parts of the workpiece 2.

[0021] Reference Figures 1-3 , Figure 5 as well as Figure 7 As shown, the self-clamping assembly is used to automatically straighten and clamp the workpiece 2 on the worktable 1, ensuring that the axis of the workpiece 2 is coaxial with the machining spindle, and providing a stable reference for subsequent machining. The self-clamping assembly includes a motor 11 fixedly installed at the bottom of the worktable 1. The output end of the motor 11 is fixedly connected to a drive rod 12. A hollow rod 14 is installed on the drive rod 12 through a damping bearing 16. The introduction of the damping bearing 16 allows the hollow rod 14 to rotate relative to the drive rod 12 when subjected to a large rotational resistance. A bevel gear 15 is fixedly installed on the top of the hollow rod 14. Multiple lead screws 9 are rotatably installed inside the worktable 1. There are three lead screws 9. Each lead screw 9 is fixedly installed with a bevel gear 10 that meshes with the bevel gear 15. When the motor 11 drives the drive rod 12 to rotate, the damping bearing 16 drives the hollow rod 14 and the bevel gear 15 to rotate, thereby driving all the lead screws 9 to rotate synchronously. The worktable 1 has multiple grooves 5 corresponding to the number of lead screws 9. Each groove 5 has a sliding rod 6 that is threadedly connected to the corresponding lead screw 9. When the lead screw 9 rotates, the sliding rod 6 moves radially along the groove 5. Each sliding rod 6 has a mounting block 7 fixedly mounted on its top, and each mounting block 7 has a clamping block 8 mounted on it via a connecting mechanism. When multiple sliding rods 6 move towards the center of the worktable 1 at the same time, they can drive multiple clamping blocks 8 to move closer to the workpiece 2 at the same time. Then, the workpiece 2 can be held in place by the clamping action of the multiple clamping blocks 8. The drive rod 12 is fixed on the workbench 1, and a grinding disc 13 is also fixedly installed on the top of the drive rod 12. When the workpiece 2 is not fixed, the rotation of the drive rod 12 can drive the workpiece 2 to rotate at the same time through the grinding disc 13. However, when the workpiece 2 is fixed, if the drive rod 12 continues to rotate, the slide rod 6 will be blocked from moving due to the reaction force of the workpiece 2. Therefore, the rotation of the drive rod 12 will not drive the hollow rod 14 to rotate. At this time, only the grinding disc 13 will rotate, which can perform preliminary deburring on the bottom end face of the workpiece 2.

[0022] Reference Figure 5 , Figure 6 as well as Figure 8 As shown, the connecting mechanism consists of a connecting block 17, a connecting groove 18, a spring 19, a guide block 20, and a three-way groove 21. The connecting block 17 is fixedly installed on the clamping block 8, the connecting groove 18 is opened on the mounting block 7, the spring 19 is installed between the connecting block 17 and the connecting groove 18, so that the clamping block 8 has a certain radial floating ability, the guide block 20 is fixedly installed on the side wall of the connecting block 17, and the three-way groove 21 is opened on the side wall of the connecting groove 18, and the three-way groove 21 cooperates with the guide block 20. The three-way groove 21 has a central groove extending radially and two lateral arc-shaped grooves symmetrically distributed circumferentially. In the initial state, the guide block 20 is located in the central groove, and the clamping block 8 can move radially. When the clamping block 8 contacts the outer circle of the workpiece 2 and is subjected to circumferential force, the guide block 20 can slide into the lateral groove, allowing the clamping block 8 to swing circumferentially. During operation, workpiece 2 is roughly placed in the center of worktable 1. Motor 11 is started, and lead screw 9 rotates, driving slide bar 6 to move towards the center. Clamping block 8 gradually approaches the outer circumference of the gear. Due to the presence of spring 19, clamping block 8 contacts the gear with a flexible force, avoiding rigid impact. When all clamping blocks 8 have contacted the gear, if there is a slight deviation between the gear center and the spindle, clamping block 8 will compress spring 19 under radial force. Simultaneously, guide block 20 slides along the lateral groove of the three-way groove 21, causing clamping block 8 to produce a slight circumferential oscillation. Furthermore, the hollow rod 14 drives the grinding disc 13 to rotate, causing the workpiece 2 to rotate simultaneously among multiple clamping blocks 8. This automatically adjusts the posture of the workpiece 2 to adapt to the multiple clamping blocks 8. As clamping continues, the clamping blocks 8 move into the mounting block 7, and finally the guide block 20 enters the radially extending middle groove at the bottom of the three-way groove 21. Then the clamping blocks 8 will return to a state that is relatively horizontal with the mounting block 7. At this time, the return of the multiple clamping blocks 8 can automatically secure the workpiece 2, achieving adaptive centering clamping.

[0023] Reference Figures 1-5 , Figures 9-11 as well as Figure 13 As shown, the end face processing assembly is used to deburr the annular groove on the end face of the workpiece 2. Its core is that the flexible processing assembly can automatically adjust the angle and position of the grinding head 27 according to the progress of grinding and deburring to achieve uniform and thorough deburring. The end face processing assembly includes a motor 22 fixedly installed on the processing plate 4. The output end of the motor 22 is connected to the rotating disk 23 rotatably via a reducer. An inner ring 24 is fixedly installed at the bottom of the rotating disk 23. The flexible processing assembly is installed between the rotating disk 23 and the inner ring 24. The flexible processing assembly consists of a movable rod 25, a fixed block 26, a grinding head 27, a rotating rod 28, a fixed plate 29, a movable groove 30, a telescopic groove 31, and a telescopic rod 32. Movable grooves 30 are provided at the bottom of both the rotating plate 23 and the inner ring 24. The movable rod 25 is slidably installed within the movable groove 30 and can move radially. The fixed block 26 is installed at the bottom of the movable rod 25. The rotating rod 28 is rotatably installed on the fixed block 26. The grinding head 27 is fixedly installed on the rotating rod 28. Fixed plates 29 are fixedly installed at both ends of the rotating rod 28. Torsion springs are installed between the fixed plate 29 and the fixed block 26. The torsion springs keep the grinding head 27 at an initial angle perpendicular to the end face in a free state. The telescopic groove 31 is opened on the side wall of the moving groove 30. The telescopic rod 32 is slidably installed in the telescopic groove 31, and the telescopic rod 32 and the moving rod 25 are engaged by a wedge-shaped surface. The moving rod 25 is provided with an inclined surface, and the end of the telescopic rod 32 is provided with an inclined surface that engages with it. When the telescopic rod 32 moves axially, it pushes the moving rod 25 to move radially through the wedge-shaped surface, thereby changing the radial position of the grinding head 27. The processing plate 4 has a groove 34. Multiple screws 33 corresponding to the number of flexible processing components are rotatably installed on the rotating disk 23 and the inner ring 24. Each screw 33 is threadedly connected to the corresponding telescopic rod 32. A chain drive structure 35 is installed between every two corresponding screws 33, so that the two screws 33 in the same group rotate synchronously. Each screw 33 located on the inner ring 24 has a fixed gear 36 fixedly installed at its top. Multiple arc-shaped racks 37 that mesh with the fixed gears 36 are fixedly installed on the inner wall of the groove 34. As the inner ring 24 rotates, the fixed gears 36 sequentially mesh with the arc-shaped racks 37. During operation, when the motor 22 drives the rotating disk 23 to rotate, the inner ring 24 rotates synchronously, thereby causing all flexible processing components to revolve around the axis of the workpiece 2. Simultaneously, the fixed gears 36 rotate with the inner ring 24, meshing with the arc-shaped racks 37 as they pass, driving the fixed gears 36 to rotate. This, in turn, drives the telescopic rod 32 to move axially via the screw 33, and then pushes the moving rod 25 downwards via the wedge-shaped surface. In this way, as the grinding head 27 revolves, its radial position changes periodically according to the meshing state of the fixed gear 36 and the arc-shaped rack 37. This allows for scanning deburring of annular grooves of different diameters. Furthermore, due to the action of the torsion spring, the grinding head 27 automatically deflects according to the inclination angle of the sidewall when it contacts the sidewall of the annular groove, ensuring that the grinding head 27 always fits the groove wall at the optimal angle. This achieves flexible adaptive angle adjustment. This design ensures that the grinding head 27 can fit tightly regardless of whether the annular groove is rectangular, trapezoidal, or other shapes, effectively removing burrs from the bottom and sidewalls of the groove. This avoids the problem of fixed-angle tools being unable to reach corners or excessively wearing down the tooth surface. Alternatively, elastic telescopic components (refer to the structural combination of spring 19, connecting block 17 and connecting groove 18) can also be installed on the fixed block 26 and the moving rod 25 to give the fixed block 26 and the moving rod 25 a certain amount of moving space to meet more complex moving trajectories.

[0024] like Figures 3-5 , Figures 10-12 and Figure 14 , Figure 15 As shown, the hole processing assembly is used to deburr multiple weight-reducing holes on workpiece 2 and simultaneously collect grinding debris to prevent secondary pollution. The hole processing assembly includes a mounting ring 38 rotatably connected to the inner ring 24. Multiple round rods 39 corresponding to the number of weight-reducing holes are rotatably mounted on the mounting ring 38. A fixing rod 40 is fixedly mounted at the bottom of each round rod 39. Multiple grinding blocks 41 are fixedly mounted on the side wall of the fixing rod 40. The grinding blocks 41 are multiple flexible brushes or abrasive blocks distributed along the axial direction, used to deburr the weight-reducing holes.

[0025] Each round rod 39 has a fixed toothed ring 42 fixedly installed on its top. The inner ring 24 has a drive toothed ring 43 fixedly installed on its side wall, which meshes with the multiple fixed toothed rings 42. When the inner ring 24 rotates, the drive toothed ring 43 drives all the fixed toothed rings 42 to rotate, thereby causing each fixed rod 40 to rotate, thus achieving the grinding and deburring treatment of the weight reduction hole.

[0026] A collection chamber 44 is provided inside the fixed rod 40. A through hole 45 communicating with the collection chamber 44 is provided on the side wall of the fixed rod 40. The through hole 45 is located at the lower end of the grinding block 41. A connecting ring 47 communicating with the collection chamber 44 is rotatably connected to the side wall of the fixed rod 40. A connecting nozzle is fixedly connected to the connecting ring 47, and the connecting nozzle can be connected to an external air extraction device. A filter screen 46 is fixedly installed inside the collection chamber 44. A sealing cover 48 is threadedly installed at the bottom of the collection chamber 44 for periodically cleaning debris. During operation, when the fixed rod 40... During rotation, the grinding block 41 grinds the inner wall of the weight reduction hole. At the same time, a vacuum device connected to the connecting nozzle creates a negative pressure in the collection chamber 44. The grinding debris is sucked into the collection chamber 44 through the through hole 45 and blocked in the chamber by the filter screen 46. The air is discharged from the connecting nozzle. Since the weight reduction hole is generally set to be through from top to bottom, collecting debris during the grinding process not only keeps the working environment clean but also avoids secondary scratches caused by debris remaining in the hole. The sealing cover 48 can be opened periodically to clean the accumulated debris.

[0027] It is worth noting that the telescopic cylinder 3, motor 11 and motor 22 used above are all existing products. Their working principle and specific models will not be described here. Among them, motor 11 and motor 22 can be selected as servo motors.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
