Description

Technical Field

[0001] This invention relates to the field of gear grinding, and in particular to a multi-station, multi-directional gear burr trimming device. Background Technology

[0002] Gears, as core components in the field of mechanical transmission, are widely used in automobiles, construction machinery, aerospace, precision machine tools, and other fields. After machining processes such as hobbing, shaping, shaving, turning, and drilling, irregular burrs, flash, and sharp edges are easily generated on the tooth tip edges, tooth flanks, tooth root fillets, and inner hole openings. If these burrs are not completely removed, they will not only affect the subsequent heat treatment, grinding, and assembly accuracy of the gears, but also lead to problems such as abnormal noise, accelerated wear, and meshing jamming during gear transmission, seriously reducing the gear transmission accuracy and service life. Therefore, gear deburring is an indispensable key process in gear manufacturing.

[0003] Existing pinion grinding and trimming structures use flexible grinding heads, which can grind multiple parts of the gear. However, in actual use, the pinion is placed on the corresponding turntable, and the grinding head can easily cause the gear to shake or even dislodge from the workstation, posing a high risk. In addition, the grinding head is usually placed at an angle, which prevents the bottom and lower surface of the gear from being ground, resulting in insufficient grinding. To solve the above problems, a multi-station, multi-directional gear burr trimming device is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in existing gear burr trimming equipment, where the small gear is placed behind the turntable, and the flexible grinding head easily causes the gear to shake or even fall off the work position, posing a safety hazard; at the same time, the inclined setting of the grinding head causes the bottom and lower surface of the gear to be unable to be ground, resulting in grinding blind spots and insufficient trimming.

[0005] The present invention adopts the following technical solution: A multi-station, multi-directional gear burr trimming device includes a worktable and a turntable on the worktable. A grinding component and a flipping component are provided on the outer edge of the turntable. A planetary gear carrier is provided below the turntable for driving the turntable to rotate. Several limiting posts are also provided on the turntable for placing gears to be ground. The limiting posts are connected to the planetary gear carrier and are used to drive the limiting posts to rotate while the turntable rotates, thereby driving the gears to rotate on the turntable. There are two sets of grinding components, located on both sides of the turntable, for grinding the gears on the turntable. The flipping component is located between the two grinding components and is used to clamp and flip the gears on the limiting posts, exposing the unground bottom and lower surface of the gears. Furthermore, the turntable is located on the surface of the worktable, and the planetary gear carrier is located inside the worktable to drive the turntable and the limiting post to rotate. The planetary gear carrier is driven by a motor inside the worktable. The planetary gear carrier includes a driving gear and a driven gear. The driving gear is driven by a motor, and a turntable is fixedly installed on the top of the driving gear to drive the turntable to rotate. There are several driven gears, which are evenly distributed on the outer edge of the driving gear and mesh with the driving gear through gears. A limiting post is fixedly installed on the upper end of the driven gear. The limiting post passes through the turntable and protrudes from the upper end of the turntable. The diameter of the driven gear is smaller than the diameter of the driving gear. Furthermore, the surface of the portion of the limiting post protruding from the turntable is provided with threaded guide grooves. There are two threaded guide grooves, which are symmetrical about the axis of the limiting post. The threaded guide grooves extend downward from the uppermost end of the limiting post to the bottommost part of the portion of the limiting post protruding from the turntable. The threaded guide grooves circumferentially surround the limiting post. A locking groove is provided at the bottom of the threaded guide grooves. Furthermore, the locking groove continues the thread direction of the threaded guide groove, and its cross-section is arc-shaped, which is used to fix the position of the gear; Furthermore, a gear to be processed is sleeved on the limiting post, and a gear sleeve is installed in the inner hole of the gear. The gear sleeve includes an upper sleeve and a lower sleeve, which are connected by threads. The upper and lower sleeves are provided with outwardly expanding bosses on their upper and lower edges. These bosses contact the upper and lower edges of the gear and are used to fix the gear sleeve on the gear. Furthermore, the lower edge of the lower sleeve has an inwardly protruding guide protrusion. The guide protrusion matches the cross-sectional size of the threaded guide groove. The guide protrusion cooperates with the threaded guide groove to drive the gear and gear sleeve to spiral downward along the threaded guide groove, which is used to place the gear on the limiting post. Furthermore, the positioning groove and the guide protrusion are at the same height, and the guide protrusion moves from the bottom end of the threaded guide groove into the positioning groove, driving the gear to rotate through the rotating limiting post; Furthermore, the polishing assembly includes a polishing frame and a polishing wheel mounted thereon. The polishing frame is equipped with an electric rotating shaft, and a polishing base is provided at the front end of the electric rotating shaft. The polishing wheel is mounted on the polishing base. The polishing frame is controlled by a motor inside the worktable to control the overall height of the polishing wheel. The electric rotating shaft is also controlled by a controller inside the worktable to control the tilt angle of the polishing wheel. Furthermore, the grinding wheel is a flexible grinding wheel, which has flexibility at the contact position with the gear to increase the contact area between the grinding wheel and the gear. The rotation direction of the grinding wheel is perpendicular to the rotation direction of the turntable and opposite to the rotation direction of the gear on the side near the outer edge of the turntable, in order to improve grinding efficiency. Furthermore, there are two sets of grinding components, which are symmetrical about the axis of the turntable. A flipping component is provided between the two grinding components. The flipping component has a flipping frame and a mechanical gripper on it. The mechanical gripper is controlled by a robotic arm and is used to pick up the gear and flip it, and then put it into the limiting post. The end of the mechanical gripper has a rotating frame controlled by the robotic arm that is opposite to the rotation direction of the limiting post, and is used to pick up the gear from the limiting post in the opposite direction.

[0006] The beneficial effects of this invention are: The multi-station structure, which combines planetary gear revolution with station rotation, enables continuous cyclic grinding of multiple gears, significantly improving batch production efficiency. At the same time, the gears rotate autonomously with the station, ensuring uniform grinding of all positions around the gears and eliminating any local grinding omissions. The locking and positioning structure, which combines a limiting post with a threaded guide groove, a locking groove, and a gear sleeve, can achieve precise locking and fixing of the gear after assembly. This effectively eliminates the problems of gear shaking, offsetting, and detaching from the work station during the grinding process, greatly improving the stability of equipment operation and production safety, and reducing the risk of equipment failure and workpiece scrap. It abandons the traditional fixed and tilting grinding structure and adopts a grinding structure that can be raised, lowered, and flipped at multiple angles. The grinding height and angle are adaptively adjusted according to the gear specifications to completely eliminate traditional grinding dead corners such as the bottom and lower surface of the gear. This achieves all-round burr repair on the entire end face and tooth surface of the gear, resulting in thorough grinding and high processing precision. Equipped with an independent automatic flipping component, it can automatically complete the gear clamping, flipping, and resetting operations without the need for manual disassembly and flipping. This high degree of automation significantly saves labor costs and improves production efficiency. The double-sided symmetrical flexible grinding wheel reverse grinding structure has good contact and uniform grinding force, which can effectively remove fine flash and burrs, while avoiding damage to the precision-machined surface of the gear, and significantly improve the product yield. With high overall structural integration, stable operation, and strong adaptability, it can meet the high-precision, batch, and dead-angle-free deburring needs of small gears of different specifications, solving the problems of incomplete grinding, poor stability, and low safety of traditional equipment. It has extremely high production economy and practicality. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0010] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0011] Example 1 This invention provides a multi-station, multi-directional gear burr trimming device, including a workbench 1 and a turntable 4 on the workbench 1. The workbench 1 has a circular turntable 4 structure that rotates on its surface. The workbench 1 has a sealed integrated planetary gear carrier 5 drive structure inside. The overall built-in drive layout can effectively save equipment space while protecting the transmission structure from external dust and iron filings, and extending the service life of the transmission structure. The planetary gear carrier 5 is driven by a motor built into the worktable 1. The planetary gear carrier 5 includes a central driving gear 6 and multiple sets of evenly arranged driven gears 7. The top of the driving gear 6 is fixedly connected to the center of the bottom of the turntable 4. During the continuous operation of the driving gear 6 driven by the motor, the upper turntable 4 can be driven to rotate horizontally at the same time, so that the multiple sets of gears 11 on the turntable 4 can be circulated to the grinding areas on both sides, realizing uninterrupted continuous grinding operation and greatly improving the processing cycle of mass production. Multiple sets of driven wheels 7 are evenly meshed and assembled on the outer circumference of the driving wheel 6 to form a stable planetary transmission structure. Each set of driven wheels 7 is vertically fixed with a limiting post 8 at its upper end. The limiting post 8 is vertically protruding from the surface of the turntable 4 and exposed, and can independently support a single gear 11 workpiece to be processed. The driven wheel 7 has a smaller overall diameter than the driving wheel 6, which makes the rotation speed of the limiting post 8 higher than the revolution speed of the turntable 4. This ensures that each gear 11 can complete multiple rotations within the time period of passing through the grinding component 2, ensuring that the entire circumference of the gear 11 can be fully ground. Each driven wheel 7 can rotate independently under the drive of the driving wheel 6 without interfering with each other. Thus, while the turntable 4 revolves as a whole, each station limiting post 8 carries the gear 11 to rotate independently, allowing the gear 11's gear ring, tooth tip, and tooth side to contact the grinding structure evenly and orderly. This avoids the problems of local grinding omissions and uneven grinding caused by traditional unidirectional fixed-point grinding, effectively improving the overall grinding consistency of the gear 11. Two threaded guide grooves 9 are symmetrically opened on the column position of the limiting post 8 exposed on the surface of the turntable 4. The two threaded guide grooves 9 are symmetrically arranged about the central axis of the limiting post 8. The threaded guide grooves 9 spiral downward from the uppermost position of the limiting post 8, completely circle the column body, and extend to the bottom of the exposed section. The regular spiral groove structure can play a role in precise guidance, limiting and sliding guidance of the guide protrusion 15 of the lower gear sleeve 12 during the assembly of the gear 11, so as to realize the spiral and smooth assembly of the gear 11. There is no need for repeated manual alignment and calibration, which greatly reduces the difficulty of manual assembly and improves the material feeding efficiency and assembly accuracy. The bottom end of the threaded guide groove 9 is followed by the locking groove 10. The locking groove 10 continues the spiral extension direction of the threaded guide groove 9 and the overall cross-section is set as an arc structure, which can match the guide protrusion 15 at the bottom of the gear sleeve 12. When the gear 11 is assembled, the guide protrusion 15 can be accurately locked into the locking groove 10. Through the single lateral and vertical limiting effect of the locking groove 10, combined with the rotation direction of the limiting post 8, the assembled gear sleeve 12 and gear 11 are locked and positioned, which limits the problems of circumferential slippage, vertical movement and radial displacement of gear 11 during high-speed grinding. This solves the defects of traditional grinding equipment that cause workpiece shaking, displacement or even separation from the workstation due to friction and impact, and improves the stability of the workpiece and the overall safety of the equipment during the grinding process. A gear sleeve 12 is provided at the center inner hole of the gear 11 to be processed. The gear sleeve 12 is assembled into a whole by the upper sleeve 13 and the lower sleeve 14 through thread engagement. The thread engagement assembly structure is easy to disassemble and assemble, and the connection is firm. The assembly spacing can be flexibly adapted according to the thickness of different gears 11. It can also be quickly disassembled and reused. The upper end edge of the upper sleeve 13 and the lower end edge of the lower sleeve 14 are both integrally provided with outwardly extending boss structures. The upper and lower bosses can be tightly fitted to the upper and lower end face edges of the gear 11 respectively. The gear sleeve 12 is firmly locked in the center of the inner hole of the gear 11 by bidirectional clamping and limiting, so that the gear 11 and the gear sleeve 12 form an integrated linkage structure, ensuring that there is no relative slippage or loosening between the gear 11 and the sleeve during subsequent grinding, and the transmission synchronization is higher. The lower end of the lower sleeve 14 is integrally provided with an inwardly protruding guide protrusion 15. The outer dimensions, thickness, and curvature of the guide protrusion 15 are all matched with the threaded guide groove 9 on the surface of the limiting post 8. During assembly, the guide protrusion 15 can be precisely inserted into the threaded guide groove 9 and slide smoothly down along the spiral groove trajectory. The gear 11 is precisely guided to sit smoothly with the sleeve as a whole, and finally the guide protrusion 15 is precisely embedded in the bottom locking groove 10, so as to achieve precise locking and positioning of the workpiece as a whole. The height dimensions of the locking groove 10 and the guide protrusion 15 are matched to ensure that the locking gap is extremely small and the positioning accuracy is extremely high. During the rotation of the limiting post 8, the locking groove 10 and the guide protrusion 15 can stably drive the gear sleeve 12 and the gear 11 to rotate synchronously, providing a reliable transmission and positioning basis for the cyclic grinding of the gear 11. Two sets of grinding components 2 are symmetrically arranged on the left and right sides of the turntable 4. The symmetrical grinding layout on both sides can simultaneously grind the rotating gear 11, improving the grinding efficiency. At the same time, the symmetrical force on both sides can offset the lateral impact force generated by grinding on one side, improving the stability of the turntable 4 rotation. The grinding assembly 2 consists of a grinding frame 16, a grinding base 18, and a flexible grinding wheel 19. The grinding frame 16 is the supporting base of the overall grinding execution structure. The overall lifting stroke and height position are independently controlled by a dedicated motor inside the worktable 1. The vertical height of the grinding wheel 19 can be adaptively and precisely adjusted according to the thickness, tooth height, and size of the gear 11 to be processed, accurately matching the grinding position of different gears 11 and adapting to the flexible grinding production needs of multiple specifications of gears 11. The grinding base 18 can be rotatably mounted on the front working end of the grinding frame 16 through an electric rotating shaft 17. The electric rotating shaft 17 can be precisely controlled by the built-in controller of the equipment to drive the grinding base 18 and the front grinding wheel 19 to achieve multi-angle tilt adjustment. The contact angle of the grinding wheel 19 can be flexibly adjusted according to the grinding requirements of different positions such as the tooth tip, tooth side, tooth root, end face, and hole of the gear 11. The grinding wheel 19 is made of flexible material to form a flexible grinding structure. It has good elasticity and fit at the contact position with the gear 11. It can adapt to the complex tooth profile of the gear 11 and cover the upper part of the gear 11, greatly increasing the grinding contact area and realizing uniform grinding with curved surface fit. This avoids the damage such as tooth surface scratches and tooth tip chipping caused by single-point force concentration in traditional rigid grinding, and effectively improves grinding accuracy and product yield. Meanwhile, the rotation direction of the grinding wheel 19 is perpendicular to the overall revolution direction of the turntable 4, and moves in the opposite direction to the rotation direction of the gear 11 on the side near the outer edge of the turntable 4. The reverse friction improves the burr removal efficiency, allowing fine flash, sharp burrs, and residual iron filings to be removed quickly, resulting in a more uniform and cleaner grinding quality. A flipping assembly 3 is centrally located between two symmetrically arranged grinding components 2. The flipping assembly 3 consists of a flipping frame 20, a controllable robotic arm, and an end mechanical gripper 21. The flipping frame 20 provides a stable installation support for the overall flipping structure, ensuring that the robotic arm operates stably without shaking. The mechanical gripper 21 achieves multi-degree-of-freedom movement through the robotic arm, which can accurately align with the gear 11 workpiece and stably clamp the gear 11 on the limiting post 8 and lift it upward from the limiting post 8 position. The robotic arm adopts a multi-degree-of-freedom controlled robotic arm commonly used in existing technologies. When the workpiece reaches the flipping area, the motor-controlled turntable 4 and limit post 8 in the worktable 1 stop rotating. After the flipping is completed, they continue to rotate. The mechanical gripper 21 is equipped with a reverse rotation frame independently controlled by the robotic arm. This frame can drive the gear 11 in the gripping state to accurately complete a 180-degree reverse flip, so that the bottom and lower surface of the gear 11, which were originally covered and could not be ground, are completely exposed upwards. After the flipping is completed, the robotic arm moves again to smoothly and accurately put the flipped gear 11 back to the original limit post 8 position, completing the automatic flipping and reset operation. The flipped gear 11 can then be transferred to the opposite grinding component 2 area with the turntable 4 to perform secondary all-round grinding on the unprocessed areas such as the bottom, lower surface, and lower tooth root. This eliminates the bottom grinding dead angles that exist in traditional inclined grinding equipment, and achieves precision deburring and finishing of the entire outer circle, end face, and tooth surface of the gear 11 without dead angles. This greatly improves the overall grinding integrity and processing quality of the gear 11.
