Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and more specifically, to a deburring device for indexable multi-station gears. Background Technology

[0002] As a key basic component in the field of mechanical transmission, the machining accuracy and surface quality of gears directly affect the reliability, noise level, and service life of the transmission system. In the mass production process of gears, whether through cutting processes such as hobbing, gear shaping, and milling, or through near-net-shape forming processes such as precision forging and powder metallurgy, burrs of varying degrees and shapes are inevitably generated on the tooth profile and other parts.

[0003] For example, the specification of the "Multi-station Fully Automatic Deburring Machine" disclosed in Chinese Utility Model Patent (Publication No.: CN221290582U) states that: by starting the drive motor, the first gear rotates and meshes with the second gear. Since the workpiece on the connecting plate is located directly below the automatic brush machine, the first telescopic controller is activated, and the automatic brush machine is used to automatically deburr the workpiece. This allows the surface of each workpiece to be polished by the automatic brush machine, making the removal of burrs more thorough and comprehensive, so that the workpiece achieves the specified flatness and the surface of the workpiece is more uniform.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In actual use, after the workpiece is positioned in the slot, only its upper surface is exposed for the brush to contact, while the mounting reference surface that contacts the bottom of the slot remains obscured, making simultaneous deburring impossible. This single-sided processing strategy means that after completing one processing cycle, if the bottom surface of the workpiece needs to be treated in the same way, manual intervention is required for secondary clamping and positioning, which not only disrupts the continuity of the production process but also significantly reduces overall processing efficiency.

[0005] Therefore, we have made improvements to this and proposed a multi-station indexable gear deburring device. Utility Model Content

[0009] A rotating plate is fixedly installed at the top of the rotating shaft. Several slots are equidistantly opened on the outer side of the top of the rotating plate. An external groove is opened at the bottom of the inner wall of the slot. A driving component is provided on the top of the support plate. A grinding component and a limiting component are respectively provided on the rear side of the top of the processing table. A flipping component is provided on one side of the top of the processing table.

[0012] As a preferred technical solution of this application, the polishing assembly includes a polishing frame fixedly installed on the back of the processing table, a second electric telescopic rod fixedly installed on the top of the polishing frame, the driving end of the second electric telescopic rod passing through the polishing frame and extending to the top of the rotating plate, and an automatic brush machine fixedly installed on the driving end of the second electric telescopic rod.

[0013] As a preferred technical solution of this application, the limiting component includes a third electric telescopic rod fixedly installed on the rear side of the top of the processing table, and a pressure plate is fixedly installed on the driving end of the third electric telescopic rod, the pressure plate being adapted to the position of the slot.

[0014] As a preferred technical solution of this application, a guide rod is fixedly installed on the top of the processing table in front of the third electric telescopic rod, and a sliding hole adapted to the guide rod is opened on the pressure plate. The pressure plate is slidably connected to the guide rod through the sliding hole.

[0015] As a preferred technical solution of this application, the drive assembly includes a first servo motor fixedly installed on the top of the support plate, a first gear fixedly installed on the drive end of the first servo motor, and a second gear fixedly installed on the outer wall of the rotating shaft, the second gear meshing with the first gear.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. Through the coordinated use of a processing table, support legs, support plate, controller, rotating plate, slot, external groove, grinding assembly, flipping assembly, first servo motor, first gear, second gear, and rotating shaft, the gear is precisely gripped by the coordinated action of the clamping plate and the bidirectional lead screw. It then rotates 180° along the vertical rail to automatically flip the gear, before returning it to the slot for processing on the other side. This achieves automated continuous operation of double-sided gear processing, completely eliminating process interruptions and repetitive positioning errors caused by manual flipping, and significantly improving processing efficiency, accuracy, and production line continuity.

[0020] 2. By using a combination of limiting components, pressure plates, guide rods, and a third electric telescopic rod, the pressure plates are driven by the third electric telescopic rod to independently clamp the gears. This ensures clamping rigidity during processing while allowing for flexible adjustment of the pressure plate's clamping position through the micro-indexing of the rotating plate. This dynamic limiting strategy effectively avoids processing blind spots caused by fixed clamping, enabling the automatic brushing machine to perform full-area deburring on the gear's upper surface. This significantly improves processing stability while ensuring the consistency and integrity of the surface treatment, solving the problem of burr residue caused by traditional fixed-point clamping.

[0032] Example 1

[0033] Please refer to Figures 1-5 A multi-station indexable gear deburring device includes a processing table 1. Symmetrically distributed support legs 2 are fixedly installed on both sides of the bottom of the processing table 1. A support plate 3 is fixedly installed on the support leg 2. A rotating shaft 14 is rotatably installed on the top of the support plate 3. The top end of the rotating shaft 14 passes through the processing table 1 and extends to the top of the processing table 1. A controller 4 is fixedly installed on one of the support legs 2.

[0034] A rotating plate 5 is fixedly installed at the top of the rotating shaft 14. Several slots 6 are equidistantly opened on the outer side of the top of the rotating plate 5. An external groove 7 is opened at the bottom of the inner wall of the slot 6. A drive assembly is provided on the top of the support plate 3. A grinding assembly 8 and a limiting assembly 9 are respectively provided on the rear side of the top of the processing table 1. A flipping assembly 10 is provided on one side of the top of the processing table 1.

[0035] Furthermore, the flipping assembly 10 includes a guide rail 16 fixedly installed on one side of the top of the processing table 1. An electric slider 17 is slidably arranged on the guide rail 16. A first electric telescopic rod 18 is fixedly installed on the top of the electric slider 17. A limit frame 19 is fixedly installed on the drive end of the first electric telescopic rod 18. A second servo motor 15 is fixedly installed on one side of the limit frame 19. The drive end of the second servo motor 15 passes through the limit frame 19 and extends into the interior of the limit frame 19. A clamping assembly is provided on the drive end of the second servo motor 15.

[0036] Furthermore, the clamping assembly includes a vertical rail 20 fixedly mounted on the drive end of the second servo motor 15. A bidirectional lead screw 22 is rotatably mounted inside the vertical rail 20. Symmetrically distributed adjusting blocks 21 are sleeved on the outer wall of the bidirectional lead screw 22. The adjusting blocks 21 are slidably mounted on the vertical rail 20. A clamping plate 23 is fixedly mounted on one side of each adjusting block 21. A third servo motor 24 is fixedly mounted at the bottom end of the vertical rail 20. The drive end of the third servo motor 24 passes through the vertical rail 20 and extends into the interior of the vertical rail 20, where it is fixedly connected to the bottom end of the bidirectional lead screw 22. This enables the two clamping plates 23 to achieve stable, centered, and adjustable clamping action, ensuring that the gear is reliably gripped and released during the flipping process.

[0037] Furthermore, the polishing assembly 8 includes a polishing frame 25 fixedly installed on the back of the processing table 1.

[0040] Example 2

[0041] The deburring device for indexable multi-station gears provided in Embodiment 1 is further optimized. Specifically, the limiting component 9 includes a third electric telescopic rod 30 fixedly installed on the rear side of the top of the processing table 1. A pressure plate 28 is fixedly installed on the drive end of the third electric telescopic rod 30, and the pressure plate 28 is adapted to the position of the slot 6.

[0042] Furthermore, a guide rod 29 is fixedly installed on the top of the processing table 1 in front of the third electric telescopic rod 30. A sliding hole adapted to the guide rod 29 is provided on the pressure plate 28, and the pressure plate 28 is slidably connected to the guide rod 29 through the sliding hole. This provides precise radial constraint and guidance for the vertical movement of the pressure plate 28, effectively preventing the pressure plate 28 from deflecting or jamming during the clamping process.

[0043] It should be noted that the controller control circuit can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0044] The usage process of the indexable multi-station gear deburring device provided by this utility model is as follows:

[0045] In the actual processing, the operator first places the gear to be processed into the matching slot 6. Then, the controller 4 starts the first servo motor 11, whose output shaft drives the first gear 12 to rotate. The first gear 12 meshes with the second gear 13 fixed on the rotating shaft 14, driving the rotating shaft 14 and the rotating plate 5 fixed to it to rotate synchronously. This moves the slot 6 containing the gear to the work position directly below the automatic brushing machine 27. At this time, the limiting component 9 is activated to constrain the gear in the slot 6. Then, the second electric telescopic rod 26 pushes the automatic brushing machine 27 downward in the vertical direction, so that it contacts the upper surface of the gear to perform deburring. After the upper surface is processed, the limiting component 9 is unlocked, and the first servo motor 11 drives the rotating plate 5 to rotate again, sending the processed gear to the position corresponding to the flipping component 10. At the same time, the gears in the subsequent work positions can continue to be processed synchronously by the grinding component 8 and the limiting component 9, realizing parallel operation. During the flipping process, the electric slider 17 moves along the guide rail 16, and the position of the limiting frame 19 is adjusted by the first electric telescopic rod 18. The second servo motor 15 drives the vertical rail 20 to move, so that the upper and lower clamping plates 23 installed on the vertical rail 20 are respectively embedded into the bottom external groove 7 of the slot 6 and cover the upper part of the gear. Then the third servo motor 24 starts, driving the bidirectional lead screw 22 to rotate. Utilizing its left-hand and right-hand thread transmission and the sliding cooperation between the adjusting block 21 and the vertical rail 20, the two clamping plates 23 move towards each other to clamp the gear. Then the first electric telescopic rod 18 lifts the limiting frame 19 to move the gear out of the slot 6. At the same time, the second servo motor 15 drives the vertical rail 20 to rotate 180° to complete the gear flipping. The above operation is performed in reverse to put the gear back into the slot 6. It is then rotated and transported by the turntable 5 to the bottom of the automatic brush machine 27 for deburring of its other surface. The flipping component 10 integrated into the conveying path enables automatic flipping during gear processing, effectively avoiding process interruptions and cumulative positioning errors caused by traditional manual secondary clamping, and significantly improving the continuity of the production line and overall processing efficiency.

[0046] In the gear machining process, when the limiting component 9 performs positioning and locking on the gear, the pressure plate 28 is driven to move vertically by controlling the third electric telescopic rod 30, so that it precisely presses against the upper surface of the gear, thereby firmly constraining the gear inside the slot 6, significantly enhancing the machining stability of the gear under the action of high-speed rotation and brush contact force. The limiting component 9 adopts an independent drive and independent control strategy, which can perform asynchronous sequential limiting of gears in each slot 6, rather than overall synchronous locking, thus forming a flexible and controllable limiting sequence during the machining process. Specifically, after the gear rotates with the rotating plate 5 to below the automatic brush machine 27, the circumferential position of the gear can be adjusted by the precise indexing or micro-rotation of the rotating plate 5, and then the third electric telescopic rod 30 is driven to press the pressure plate 28 against different areas of the upper surface of the gear. This variable clamping position strategy effectively avoids the process blind spots caused by the pressure plate 28 always being fixed to cover the same local area, which prevents the burrs in the blocked area from being effectively removed by the automatic brushing machine 27. This achieves full coverage of deburring on the upper surface of the gear, and further improves the consistency and integrity of the surface treatment while ensuring clamping stability.
