Abstract

The application belongs to the technical field of machining, in particular to a horizontal correction mechanism of a rotating platform for hypoid gear machining, which comprises a main table body, observation components and a correction component, the correction component is arranged at the middle of the inner wall of the main table body, and the observation components are symmetrically arranged on both sides of the correction component; the correction component comprises a turnover pair of discs, a rubber connecting cylinder, an inner controller and an adjusting element, the turnover pair of discs on the upper and lower sides are limited in the initial state due to the connection of the rubber connecting cylinder and the adjusting element and other components, and remain in a parallel state. Since the turnover pair of discs can actively change their own deflection angles through the adjusting element, and the turnover pair of discs can also perform axial rotation motion through the adjusting element, during actual machining of the hypoid gear, dynamic adjustment work can be performed according to the required deflection angle of the gear, since the deflection only occurs on the inner side of the limiting inner ring, only fine adjustment work needs to be performed during actual adjustment, so as to achieve the effect of rapid adjustment.

Description

Technical Field

[0001] This invention belongs to the field of machining technology, specifically a horizontal correction mechanism based on a rotary platform for Hybo gear machining. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears can be classified into parts such as teeth, tooth grooves, end faces, normal faces, addendum circles, root circles, base circles, and pitch circles according to their structure. Commonly used steels for manufacturing gears include tempered steel, quenched steel, carburized and quenched steel, and nitrided steel. Existing rotary platforms for gear machining cannot guarantee that they are in a horizontal state during machining, which can easily affect the accuracy of subsequent machining.

[0003] The existing publication number CN219074590U describes a horizontal correction structure based on a rotary platform for processing hybo gears. A level ruler allows for constant monitoring of the machining table's level. A servo motor drives a hybo gear placed on top of the rotary table to rotate, facilitating post-processing. However, in practice, adjustments are still made by visually inspecting the machining table's angle for horizontality. This subjective approach is prone to significant errors, necessitating improvements to the device for more rigorous machining operations. Summary of the Invention

[0004] To address the problem of errors easily arising from visual inspection in existing technologies, the technical solution adopted in this invention is: a horizontal correction mechanism based on a rotary platform for Hybo gear processing, comprising a main platform, an observation component, and a correction component. The correction component is located in the middle of the inner wall of the main platform, and the observation component is symmetrically arranged on both sides of the correction component. The corrective component includes a pair of flipping discs, a rubber connecting cylinder, an internal controller, and an adjustment element. In the initial state, the flipping discs on the upper and lower sides remain parallel due to the connection between the rubber connecting cylinder and the adjustment element. The upper and lower ends of the rubber connecting cylinder are always connected to the flipping discs on both sides. However, when the flipping discs are tilted, the rubber connecting cylinder can bend and deform to maintain the connection between the two pairs of discs. The inner cavity of the rubber connecting cylinder is uniformly provided with through slots. The outer surface of the inner controller is connected to the outer surface of the adjusting element through a plug-in connecting plate. The inner controller controls the adjusting element through the plug-in connecting plate. The inner wall of the flip plate is provided with a rotary groove, and the upper surface of the upper flip plate is provided with a gear slot. The inner controller controls the upper and lower ends of the adjusting element to expand and contract through the plug-in connecting plate, thereby pushing the corresponding position of the upper flip plate upward.

[0005] Furthermore, the corrective component also includes: The main control box has a vertical push rod slidably connected at its axis. The top of the vertical push rod extends through a large through-hole to the interior of the lower flip-up disc, and the top of the vertical push rod is inserted into the axis at the bottom of the inner controller. Since the main control box ensures that the inner controller is in a horizontal state through the vertical push rod, the inner controller can ensure that the middle of the externally set adjustment element is also in a horizontal state through the plug-in connecting plate. The suction disk has its outer surface engaged with the middle of the upper flip disk. Iron filings that detach from gear processing will be collected in the middle of the upper flip disk through the suction disk, awaiting unified processing after processing.

[0006] Furthermore, the adjusting element includes: A bidirectional air pump, wherein air inlets are uniformly opened on the outer surface of the bidirectional air pump housing; The groove end cap has an outer surface that is rotatably connected to the inner wall of the flip plate through a rotary groove, and a ball groove is provided at the top of the inner cavity of the groove end cap. The compression connecting cylinder has its bottom end inserted into the shaft center of the inner cavity of the bidirectional air pump, and its top end inserted into the middle of the outer surface of the groove end cover. The bidirectional air pump can perform different pressure control operations on the upper and lower compression connecting cylinders respectively, so that the upper and lower compression connecting cylinders can extend and retract by different lengths. In turn, by pushing the groove end cover, the tilt angle of the upper flip plate is changed.

[0007] Furthermore, the adjusting element also includes: The ball drum has its outer surface inserted into the inner cavity of the groove end cap. Friction balls are rotatably connected to the top of the inner cavity of the ball drum, and the top of the friction balls extends to the outside of the groove end cap through a ball groove. The outer surface of the friction balls is rolledly connected to the inner wall of the flipping disc through a rotary groove. No matter how the flipping disc is tilted, the end of the groove end cap is always inserted into the rotary groove of the flipping disc. Therefore, the ball drum can drive the flipping disc to rotate around its axis by rotating the friction balls and using rolling friction.

[0008] Furthermore, the main platform includes: A fixed base, wherein adjusting rods are evenly arranged on the upper surface of the fixed base, and the bottom of the main control box is inserted into the upper surface of the fixed base; A support plate, the lower surface of which is inserted into the top end of an adjusting rod, and a guide groove is provided on the upper surface of the support plate.

[0009] Furthermore, the main platform also includes: A limiting inner ring, the outer surface of which is sleeved with the axis of the inner cavity of the support plate; The side sealing strip has its outer surface engaged with the inner wall of the inner limiting ring, and its inner wall rotatably connected to the outer surface of the flipping disc. To ensure that the flipping disc has enough space to tilt, a clearance is left between the flipping disc and the inner limiting ring. At the same time, the clearance is sealed by the side sealing strip to prevent processing debris from falling in. When the flipping discs on the upper and lower sides tilt, their outer surfaces are connected to the inner limiting ring through the rubber side sealing strip, at which time the side sealing strip will deform.

[0010] Furthermore, the observation component includes: A power board, wherein a display screen is provided on the outer surface of the power board; A bent guide plate, the bottom end of which is inserted into the inner cavity of the power board; A guide gasket, the bottom of which is inserted into the top of the bent guide plate; The scanner is located on top of the bent guide plate.

[0011] Furthermore, the scanner includes: The arc-shaped outer shell has its bottom connected to the upper surface of the support plate via a guide groove, and its two ends are symmetrically connected with connecting rods. The bottom of the inner cavity of the arc-shaped outer shell is provided with a guide groove, and the upper surface of the guide pad is slidably connected to the inner cavity of the arc-shaped outer shell through the guide groove.

[0012] Furthermore, the scanner also includes: Signal tubes, which are evenly inserted into the outer surface of the arc-shaped outer shell; The detection head is inserted into the axis of the inner cavity of the signal tube. The arc-shaped outer shell can rotate along the guide groove on the upper surface of the support plate, thereby changing the detection range of the detection head and achieving the effect of comprehensive observation with fewer detection heads. When the arc-shaped outer shell rotates, the guide pad inserted into the guide groove slides relatively, so the guide pad and the bent guide plate can supply power to the detection head and receive the image signal while maintaining a relatively stationary state.

[0013] The beneficial effects of this invention are as follows: 1. This device uses a rotating disc at the center of the support plate to mount the gear. Since the rotating disc can actively change its own deflection angle through the adjustment element, and the rotating disc can also rotate on its own axis through the adjustment element, the actual machining of Hypo gears can be dynamically adjusted according to the required deflection angle of the gear. Since the deflection only occurs inside the inner ring of the limiting ring, only fine-tuning is required during actual adjustment to achieve a rapid adjustment effect.

[0014] 2. During actual gear processing, the gears are constantly subjected to impact forces. At this time, the rotating disc supporting the gears will also be unable to stabilize its deflection angle due to the impact. In addition, the gear processing will generate debris. Therefore, considering all factors, rubber side sealing strips are provided on the rotating discs and the inner ring of the limiting ring. On the one hand, the rubber material absorbs the impact force on the rotating discs and plays a buffering role. On the other hand, it can prevent the debris generated during processing from falling below the support plate, so that it can be recycled by adsorbing the disk.

[0015] 3. When reset is required, the bidirectional air pump stops pressurizing. At this time, the compression cylinders on the upper and lower sides will quickly depressurize, and then the side sealing strip will quickly reset and tighten under the action of elastic potential energy, pulling the upper and lower flip plates back to a state parallel to the support plate. This achieves the reset of the flip plates in the shortest possible time and ensures that the flip plates are in a horizontal state, thereby correcting the gears and returning them to a horizontal position.

[0016] 4. The device uses an assembled surround scanner that surrounds the gear to perform lateral horizontal monitoring of the gear supported by the upper flip plate. Since the scanner is always located on a support plate parallel to the ground, it will not cause monitoring errors due to vibration or tilting during gear processing. The monitoring results are transmitted to the display screen through screen feedback so that the operator can make dynamic adjustments. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Example 1, please refer to Figures 1-4 This invention provides a technical solution: a horizontal correction mechanism based on a rotary platform for Hybo gear processing, comprising a main platform 1, an observation component 3, and a correction component 2. The correction component 2 is disposed in the middle of the inner wall of the main platform 1, and the observation component 3 is symmetrically disposed on both sides of the correction component 2. The corrective component 2 includes a pair of flipping discs 24, a rubber connecting cylinder 25, an internal controller 23, and an adjusting element 4. In the initial state, the flipping discs 24 on the upper and lower sides remain parallel due to the connection between the rubber connecting cylinder 25 and the adjusting element 4, and the upper and lower ends of the rubber connecting cylinder 25 are always connected to the flipping discs 24 on both sides. However, when the flipping discs 24 are tilted, the rubber connecting cylinder 25 can bend and deform to maintain the connection between the two pairs of discs. The inner cavity of the rubber connecting cylinder 25 is evenly provided with through slots. The outer surface of the inner controller 23 is connected to the outer surface of the adjusting element 4 through the plug-in connecting plate 27. The inner controller 23 controls the adjusting element 4 through the plug-in connecting plate 27. The inner wall of the flip plate 24 is provided with a rotary groove, and the upper surface of the upper flip plate 24 is provided with a gear slot. The inner controller 23 controls the upper and lower ends of the adjusting element 4 to expand and contract through the plug-in connecting plate 27, thereby pushing the corresponding position of the upper flip plate 24 upward.

[0021] Corrective component 2 also includes: The main control box 21 has a vertical push rod 22 slidably connected at its axis. The top of the vertical push rod 22 extends through a large through-hole to the interior of the lower flip plate 24, and the top of the vertical push rod 22 is inserted into the axis at the bottom of the inner controller 23. Since the main control box 21 ensures that the inner controller 23 is in a horizontal state through the vertical push rod 22, the inner controller 23 can ensure that the middle part of the externally set adjustment element 4 is also in a horizontal state through the plug-in connecting plate 27. The outer surface of the adsorption disk 26 engages with the middle part of the upper flip disk 24. Iron filings that detach from gear processing will gather in the middle part of the upper flip disk 24 through the adsorption disk 26, waiting for unified processing after processing.

[0022] Adjustment element 4 includes: A two-way air pump 41 has air inlets evenly distributed on the outer surface of its housing. The outer surface of the groove end cap 43 is rotatably connected to the inner wall of the flip plate 24 through a rotary groove, and a ball groove is provided at the top of the inner cavity of the groove end cap 43. The compression connecting cylinder 42 is inserted at its bottom end into the shaft of the inner cavity of the bidirectional air pump 41, and at its top end into the middle of the outer surface of the groove end cover 43. The bidirectional air pump 41 can perform different pressure control operations on the upper and lower compression connecting cylinders 42, thereby causing the upper and lower compression connecting cylinders 42 to extend and retract by different lengths. In turn, by pushing the groove end cover 43, the tilt angle of the upper flip plate 24 is changed.

[0023] Adjustment element 4 also includes: The outer surface of the ball drum 44 is inserted into the inner cavity of the groove end cover 43. The top of the inner cavity of the ball drum 44 is rotatably connected to a friction ball 45, and the top of the friction ball 45 extends to the outside of the groove end cover 43 through the ball groove. The outer surface of the friction ball 45 is rolledly connected to the inner wall of the flip plate 24 through the rotary groove. No matter how the flip plate 24 is tilted, the end of the groove end cover 43 is always inserted into the rotary groove of the flip plate 24. Therefore, the ball drum 44 can drive the flip plate 24 to rotate around its axis by rotating the friction ball 45.

[0024] The gear is placed flat on the upper flip plate 24. After the gear is simply fixed by the slot, the gear is rotated for machining.

[0025] The internal controller 23 activates the ball drum 44 inside each adjustment element 4, causing the friction balls 45 to rotate. The rolling friction drives the upper flip plate 24 to rotate, thereby causing the gear to rotate.

[0026] When machining gears, the horizontal position of the gear can be monitored by the external observation component 3. If the gear is skewed, the skew angle error can be measured by the display screen 32 on the outside of the power board 31, and then adjustment can be made.

[0027] Since the gears are attached to the upper surface of the upper flipping disc 24, the effect of changing the gears' deflection can be achieved by changing the deflection of the upper flipping disc 24. Specifically, the internal controller 23 pressurizes the compression cylinder 42 at the position to be lifted by controlling the bidirectional air pump 41 at a specific point. This causes the extended compression cylinder 42 to lift the upper flipping disc 24, achieving the effect of the flipping disc 24 deflecting to the side. Meanwhile, the compression cylinder 42 at the opposite position contracts to achieve a matching effect.

[0028] When the upper flip plate 24 tilts to the side, in order to ensure overall stability, the lower flip plate 24 also needs to tilt to the side simultaneously, so as to keep the upper and lower flip plates 24 parallel. When the flip plate 24 tilts to the side, it will exert a traction force on the surrounding side sealing strip 16, causing the side sealing strip 16 to undergo elastic deformation. Therefore, when it is necessary to reset, the bidirectional air pump 41 stops pressurizing. At this time, the compression cylinders 42 on the upper and lower sides will quickly depressurize, and then the side sealing strip 16 will quickly reset and tighten under the action of elastic potential energy, pulling the upper and lower flip plates 24 back to a state parallel to the support plate 13.

[0029] Example 2, please refer to Figures 1-7 The present invention provides a technical solution: the main body 1 includes: A fixed base 11 is provided, and adjusting rods 12 are evenly arranged on the upper surface of the fixed base 11. The bottom of the main control box 21 is inserted into the upper surface of the fixed base 11. The support plate 13 has its lower surface inserted into the top end of the adjusting rod 12, and its upper surface has a guide groove 14.

[0030] Main body 1 also includes: The inner ring 15 is restricted, and the outer surface of the inner ring 15 is sleeved with the axis of the inner cavity of the support plate 13. The side sealing strip 16 has its outer surface engaged with the inner wall of the inner limiting ring 15, and its inner wall rotatably connected to the outer surface of the flipping disc 24. To ensure that the flipping disc 24 has enough space to tilt, a clearance is left between the flipping disc 24 and the inner limiting ring 15. At the same time, the clearance is sealed by the side sealing strip 16 to prevent processing debris from falling in. When the flipping disc 24 on the upper and lower sides tilts, its outer surface is connected to the inner limiting ring 15 by the rubber side sealing strip 16, at which time the side sealing strip 16 will deform.

[0031] Observation component 3 includes: A power board 31 has a display screen 32 on its outer surface. The bottom end of the bent guide plate 33 is inserted into the inner cavity of the power board 31. The bottom of the guide pad 34 is inserted into the top of the bent guide plate 33; Scanner 5 is positioned on top of the bending guide plate 33.

[0032] Scanner 5 includes: The arc-shaped outer shell 51 has its bottom connected to the upper surface of the support plate 13 via a guide groove 14, and its two ends are symmetrically connected with connecting rods 53. A guide groove 52 is provided at the bottom of the inner cavity of the arc-shaped outer shell 51, and the upper surface of the guide pad 34 is slidably connected to the inner cavity of the arc-shaped outer shell 51 through the guide groove 52.

[0033] Scanner 5 also includes: Signal tubes 54 are evenly inserted into the outer surface of the arc-shaped housing 51. The detection head 55 is inserted into the axis of the inner cavity of the signal tube 54. The arc-shaped outer shell 51 can rotate along the guide groove 14 on the upper surface of the support plate 13, thereby changing the detection range of the detection head 55 and achieving the effect of comprehensive observation with fewer detection heads 55. When the arc-shaped outer shell 51 rotates, the guide pad 34 inserted into the guide groove 52 slides relative to each other, so the guide pad 34 and the bent guide plate 33 can supply power to the detection head 55 and receive the image signal while maintaining a relatively stationary state.

[0034] After the gear is placed flat on the upper part of the support plate 13, the scanner 5 is installed on the outside of the gear. The scanners 5 on the front and rear sides are inserted into the guide slots 14 on both sides of the support plate 13, and then connected to form a ring structure surrounding the outside of the gear. At the same time, the guide pad 34 is also inserted into the guide slot 52 for signal transmission. Since the scanner 5 is placed flat on the upper surface of the support plate 13, the scanner 5 always remains horizontal.

[0035] During gear machining, the arc-shaped outer shell 51 can be manually rotated to rotate around the guide groove 14 of the support plate 13, so that the signal tube 54 can sweep across the entire outer surface of the gear through the probe end 55, thereby observing the gear's deflection angle in a horizontal state.

[0036] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
