[0002] In industries such as machinery manufacturing and automotive parts processing, gear chamfering is a crucial process for ensuring gear assembly compatibility and transmission stability, requiring stringent precision in angle accuracy and surface flatness. To prevent chamfering deviations from affecting subsequent equipment operation, a correction device is needed to precisely machine and correct deviations in the gear chamfer, meeting the requirements of high-precision transmission systems.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 3This utility model provides an embodiment of a gear chamfering machine correction device, including a limiting sleeve 5 and a drive motor 15. Multiple sliding plates 6 are slidably connected inside the limiting sleeve 5 and slide radially inside the limiting sleeve 5, driving the connecting block 7 to move, thereby pushing the arc-shaped clamping plate 8 to converge towards the center. It is a direct structure for performing gear clamping action. The position of the arc-shaped clamping plate 8 is changed by its own sliding. The front end of the sliding plate 6 is fixedly connected to the connecting block 7 to transmit the moving force of the sliding plate 6 to the arc-shaped clamping plate 8, so that the arc-shaped clamping plate 8 moves synchronously with the sliding plate 6, playing a role in force transmission, so that the sliding energy of the sliding plate 6 can be effectively converted into the convergence action of the arc-shaped clamping plate 8.

[0013] An arc-shaped clamping plate 8 is fixedly connected to the front end of the connecting block 7. Pushed by the connecting block 7, it moves towards the center of the limiting sleeve 5. Multiple clamping plates clamp the gears from different directions during operation, stabilizing them in the center position and preventing gear displacement during machining. This provides a stable foundation for calibration. A rack plate 9 is provided on the outside of the sliding plate 6 to convert the rotation of the transmission gear 10 into its own linear displacement. Through its connection with the sliding plate 6, the rack plate 9 transmits the displacement force to the sliding plate 6, becoming the power transmission medium for the sliding of the sliding plate 6. This connects the movement of the transmission gear 10 and the sliding plate 6. Multiple rack plates 9 are meshed with multiple transmission gears 10. Multiple transmission gears 10 are rotatably connected inside the limiting sleeve 5, receiving power from the transmission motor 11 and rotating. Through meshing with the gear ring 12, the power is synchronously transmitted to other transmission gears 10. Multiple sets of transmission gears 10 rotate in tandem, providing a power transmission path for the displacement of the rack plate 9. The right end of the transmission gear 10 is fixedly connected to the left end of the limiting sleeve 5. The rear end of one of the transmission gears 10 is fixedly connected to a transmission motor 11 as the power source. After starting, it provides driving force for the rotation of the transmission gear 10, initiating the gear clamping process. This is the initial power input structure for achieving stable gear clamping, driving the subsequent linkage components to operate. The limiting sleeve 5 is internally connected to a toothed ring 12. Through its meshing relationship with multiple transmission gears 10, the rotation of a single transmission gear 10 can link with the other transmission gears 10, ensuring the consistency of rotation of each transmission gear 10. This allows the sliding plate 6 to slide synchronously along the radial direction, maintaining the uniformity of the clamping action. The toothed ring 12 is meshed with multiple transmission gears 10.

[0014] Referring to Figures 1-2, a movable component is rotatably connected to the outside of the limiting sleeve 5. The movable component includes a support ring 4 rotatably connected to the outside of the limiting sleeve 5, with its bottom end fixed to the electric slider 3. By sliding the electric slider 3, the limiting sleeve 5 and the gear move horizontally, achieving coarse adjustment of the gear's horizontal position and adjusting the initial machining position. The inside of the support ring 4 is rotatably connected to the outside of the limiting sleeve 5, and the bottom end of the support ring 4 is fixedly connected to the electric slider 3, which slides along the electric slide rail 2. By controlling its sliding direction and distance, the support ring 4, the limiting sleeve 5, and the gear are driven, which is the actuator for coarse horizontal adjustment of the gear, giving controllability to the horizontal displacement. The bottom end of the electric slider 3 is internally slidably connected to two electric slide rails 2, which provide a sliding track for the electric slider 3, limit its sliding path, and ensure that the trajectory is stable when the electric slider 3 drives the gear to move horizontally. It is the basic support structure for coarse horizontal adjustment and ensures the accuracy of displacement.

[0015] The bottom ends of the two electric slide rails 2 are fixedly connected to the main body 1 of the device, which serves as the load-bearing frame of the entire device. This provides installation space and support for components such as the electric slide rails 2 and the electric push rods 13, allowing the various structures to be assembled in an orderly manner and work together. This is the basic carrier for the operation of the device. The top of the inner wall of the main body 1 is fixedly connected to the electric push rod 13. Through its extension and retraction, the push rod 13 drives the drive motor 15 to move vertically. Adjusting the height of the drive motor 15 allows the detection and processing mechanism 20 to be initially aligned with the gear to be processed, thus achieving vertical position adjustment. The right end of the drive motor 15 is slidably connected to the limit plate 14. The bottom end of the electric slider 3 is slidably connected to the bottom of the inner wall of the main body 1. The output end of the electric push rod 13 is fixedly connected to the top of the drive motor 15. In addition to serving as the power source for processing and adjustment, the limit plate 14 at its right end provides guidance and limitation for its vertical movement, ensuring that the trajectory of the electric push rod 13 is stable when it is driven to rise and fall, and avoiding deviation that affects the processing alignment. The bottom end of the drive motor 15 is fixedly connected to two fixed plates 22.

[0016] Two sliding sleeves 16 are fixedly connected to the left end of the drive motor 15, providing a rotational mounting base for the threaded rod 17 and limiting the sliding direction of the sliding block 18. This allows the sliding block 18 to slide stably along the axial direction of the sliding sleeve 16, ensuring the linearity and controllability of the machining adjustment action. Two threaded rods 17 are fixedly connected to the drive end of the drive motor 15 and are driven to rotate synchronously. Utilizing the threaded connection with the sliding block 18, the rotation is converted into axial displacement of the sliding block 18, which is the power component for adjusting the angle of the machining mechanism 20 and the pointing of the file 21. The external threaded connection of the threaded rod 17 is to the sliding block 18, which slides along the sliding sleeve 16. When moving, it drives the internal... The connecting plate 19 is displaced, serving as the power transmission carrier for the angle adjustment of the processing mechanism 20. It connects the threaded rod 17 and the connecting plate 19. The outside of the threaded rod 17 is rotatably connected to the inside of the sliding sleeve 16, and the outside of the sliding block 18 is slidably connected to the inside of the sliding sleeve 16. A detection mechanism is provided at the close end of the two sliding blocks 18. The detection mechanism includes two connecting plates 19 that move with the sliding blocks 18, slide inside the processing mechanism 20 and drive its displacement. By means of the rotational connection between the processing mechanism 20 and the fixed plate 22, the linear displacement is converted into an angle change of the processing mechanism 20, and the direction of the file 21 is initially adjusted. The outside of the two connecting plates 19 is rotatably connected to the inside of the two sliding blocks 18 respectively.

[0017] Referring to Figures 1-2, a processing mechanism 20 is slidably connected to one end of two connecting plates 19 and rotatably connected to a fixed plate 22 at its bottom. When the mechanism is displaced by the connecting plates 19, its angle changes due to the limitation of the fixed plate 22, adjusting the direction of the file 21. This is the execution structure for adjusting the angle of the file 21, adapting to the processing angle requirements. The top of the processing mechanism 20 is equipped with a file 21 that directly contacts the chamfered surface of the gear. By cutting, the chamfer angle and flatness are corrected. This is the final execution tool for achieving the correction processing, transforming mechanical actions into actual processing effects. The file 21 is externally fixedly connected to a connecting sleeve 23, which accommodates components such as the telescopic rod 24 and spring 25, providing integrated installation space for the detection structure. This allows the detection and processing functions to be realized collaboratively on the file 21, integrating the detection and processing links. The top of the inner wall of the connecting sleeve 23 is fixedly connected to a telescopic rod 24 with a spring 25, providing elastic support and displacement guidance for the clamping block 26. This allows the clamping block 26 to elastically extend and retract when it contacts the gear, ensuring sensitive and stable pressure signal feedback and avoiding rigid damage to the gear.

[0018] A spring 25 is sleeved on the outside of the telescopic rod 24. In the compressed state, it applies an elastic force to the clamping block 26, keeping the clamping block 26 in contact with the detector 27. When the file 21 approaches the gear, the elastic force causes the clamping block 26 to quickly return a pressure signal. The bottom end of the telescopic rod 24 is fixedly connected to the clamping block 26 and slidably connected inside the connecting sleeve 23. The bottom end contacts the detector 27. When the file 21 approaches the gear, it first contacts the gear surface and transmits pressure, converting physical contact into a pressure signal, providing a trigger basis for detection. One end of the spring 25 is fixedly connected to the top of the inner wall of the connecting sleeve 23, and the other end of the spring 25 is fixedly connected to the top of the clamping block 26. The bottom end of the processing mechanism 20 is rotatably connected to the inside of the two fixed plates 22, providing a rotational connection basis for the bottom end of the processing mechanism 20. This limits the displacement of the processing mechanism 20, converting its displacement into an angle change. It is a key limiting component for the angle adjustment of the file 21, ensuring orderly angle adjustment.

[0019] The clamping block 26 is slidably connected to the inside of the connecting sleeve 23. The outside of the detector 27 is in contact with the bottom end of the clamping block 26. The detector 27 is slidably connected to the bottom end of the inner wall of the connecting sleeve 23 to receive the pressure signal of the clamping block 26. Combined with the analysis of the control system, the gear position and angle deviation are accurately detected, providing data support for correction machining. It is a key detection component for precision closed-loop control.

[0020] Working principle: After the device is started, the drive motor 11 works first, and its drive end drives the drive gear 10 fixedly connected to it to rotate. Since the gear ring 12 meshes with multiple drive gears 10, and all drive gears 10 are rotatably connected inside the limiting sleeve 5, the rotation of a single drive gear 10 will synchronously drive the other drive gears 10 through the gear ring 12. At this time, the rack plate 9 meshing with the drive gear 10 undergoes linear displacement as the gear rotates, and the rack plate 9 is fixedly connected to the sliding plate 6, causing the sliding plate 6 to slide radially inside the limiting sleeve 5.

[0021] The connecting block 7 at the front end of the sliding plate 6 moves synchronously, pushing the arc-shaped clamping plate 8 towards the center of the limiting sleeve 5. The multiple arc-shaped clamping plates 8 work together to stably clamp the gear to be processed at the center position of the limiting sleeve 5, ensuring no displacement deviation during gear processing and providing a basis for subsequent correction.

[0022] After the gear clamping is completed, the moving component is activated to adjust the gear's spatial position. The support ring 4 is rotatably connected to the outside of the limiting sleeve 5, and the electric slider 3 fixed at its bottom can slide along the electric slide rail 2. By controlling the sliding direction and distance of the electric slider 3, the support ring 4 drives the limiting sleeve 5 and the gear to move on the horizontal plane, thereby achieving coarse adjustment of the gear's horizontal position.

[0023] Simultaneously, the electric push rod 13 at the top of the inner wall of the main body 1 extends and retracts, and its output end is fixedly connected to the top of the drive motor 15, which can drive the drive motor 15 to move vertically and adjust the height of the drive motor 15 so that the subsequent detection and processing mechanism 20 is initially aligned with the gear to be processed. The limiting plate 14 slidably connected to the right end of the drive motor 15 provides guidance and limitation for vertical movement, ensuring the stability of the displacement process.

[0024] After the coarse position adjustment is completed, the drive motor 15 starts, and its drive end drives the two threaded rods 17 to rotate synchronously. Since the threaded rods 17 are rotatably connected to the inside of the sliding sleeve 16, and the sliding block 18 is threadedly connected to the threaded rods 17 and slidably connected to the inside of the sliding sleeve 16, when the threaded rods 17 rotate, the sliding block 18 slides along the axial direction of the sliding sleeve 16.

[0025] The connecting plate 19, which is rotatably connected inside the sliding block 18, moves with it, slides inside the processing mechanism 20, and drives the processing mechanism 20 to move. Because the bottom end of the processing mechanism 20 is rotatably connected inside the two fixed plates 22, the fixed plates 22 limit it. When the processing mechanism 20 moves, the angle changes, thereby adjusting the direction of the file 21 so that it is initially aligned with the chamfered area of ​​the gear.

[0026] Meanwhile, inside the connecting sleeve 23 fixed to the outside of the file 21, the spring 25 sleeved on the outside of the telescopic rod 24 is in a compressed state, applying an elastic force to the bottom clamping block 26. The clamping block 26 is slidably connected inside the connecting sleeve 23, and its bottom end contacts the detector 27. When the file 21 approaches the gear, the clamping block 26 contacts the gear surface and feeds back a pressure signal. After receiving the signal, the detector 27, in conjunction with the control system, accurately detects the gear's position and angular deviation, providing data for correction processing.

[0027] Based on the deviation data fed back by the detector 27, the drive motor 15 continuously drives the threaded rod 17 to rotate, and the sliding block 18 continues to slide, driving the processing mechanism 20 to adjust its angle through the connecting plate 19, so that the file 21 accurately fits the chamfered surface of the gear to be corrected. During the processing, the moving components work together continuously: the electric slider 3 is finely adjusted along the electric slide rail 2 to change the horizontal position of the gear; the electric push rod 13 extends and retracts in a timely manner to adjust the height of the drive motor 15, ensuring that the file 21 fully covers the internal and external chamfered areas of the gear. Under the cutting action of the file 21, the angle and flatness of the gear chamfer are gradually corrected.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
