DETAILED DESCRIPTION

[0026] like Figures 1 to 5 As shown, the present invention is an intelligent gear shaft processing device, including a grinding wheel 1 and two groups of tooth side support assemblies 2 arranged on both sides of the grinding wheel 1. The grinding wheel 1 is circular as a whole, and the outer side is a conical structure corresponding to the tooth groove. The two groups of tooth side support assemblies 2 are symmetrical relative to the grinding wheel 1.

[0027] Specifically, the tooth side support assembly 2 includes a telescopic support frame 3, a connecting bracket 4, a first telescopic device 5, a fixed disk 6, a connecting plate 7, a first locking piece 8 and a contour tooth 9. The output end of the telescopic support frame 3 can be telescopic. A transmission shaft 10 is rotatably arranged between the output ends of the telescopic support frames 3 of the two groups of tooth side support assemblies 2. The grinding wheel 1, two fixed disks 6, and two contour teeth 9 are all located between the output ends of the two telescopic support frames 3. The grinding wheel 1 is connected to the transmission shaft 10 and is driven to rotate by the rotating drive assembly.

[0028] The fixed disk 6 is connected to the output end of the telescopic support frame 3, and its center is pivotally connected to the connecting plate 7. The inner end of the connecting plate 7 is rotatably connected to the fixed disk 6 and can be locked with the fixed disk 6 by the first locking piece 8. The outer end of the connecting plate 7 is connected to the profiling tooth 9, so that the profiling tooth 9 can rotate around the inner end of the connecting plate 7 to adaptively adjust the displacement, so as to facilitate the pressing of the gear teeth; the output end of the telescopic support frame 3 is also fixedly connected to the connecting bracket 4, which is connected to the connecting bracket 4 by screws arranged at the bottom of the telescopic support frame 3. The two ends of the first telescopic device 5 are respectively hinged to the connecting bracket 4 and the middle part of the connecting plate 7. The connecting plate 7 is made of elastic material. The telescopic movement of the first telescopic device 5 can drive the profiling tooth 9 at the outer end of the connecting plate 7 to press the gear tooth side of the gear.

[0029] In this embodiment, an arc-shaped through groove 11 is provided on the side of the fixed plate 6, and a first rotating shaft 12 is fixed to the inner end of the connecting plate 7. The first rotating shaft 12 is perpendicular to the surface of the fixed plate 6, and the first rotating shaft 12 passes through the arc-shaped through groove 11. The first rotating shaft 12 can slide along the arc-shaped channel, and the first rotating shaft 12 and the fixed plate 6 can be locked by the first locking member 8. A fan-shaped groove 13 is provided on the outer side of the fixed plate 6 for the connecting plate 7 to give way, so that the connecting plate 7 can be protected by the fan-shaped groove 13 to avoid interference with surrounding structures.

[0030] In this embodiment, the outer end of the connecting plate 7 is fixedly connected to the second rotating shaft 14, the profiling tooth 9 is pivotally connected to the second rotating shaft 14, and the profiling tooth 9 and the second rotating shaft 14 are locked by a second locking member 15. Before machining, the second locking member 15 can be loosened to adjust the position of the profiling tooth 9 to make it more suitable for the arrangement of the gear tooth position, and then its position is locked by the second locking member 15 so that its position can be adjusted, allowing it to support the gear tooth more compactly.

[0031] In this embodiment, the shape of the profiling tooth 9 is adapted to the tooth groove shape of the gear. A ball groove 16 is provided on the side of the profiling tooth 9. A ball 17 is rolled in the ball groove 16. The profiling tooth 9 rolls with the surface of the gear tooth through the ball 17. Through the support of the ball 17, the damage to the gear during the support process can be reduced, and the support surface can be effectively protected.

[0032] In this embodiment, two groups of tooth side support assemblies 2 are fixed on a bottom plate 18 at the same time. A base 19 is arranged below the bottom plate 18. One side of the bottom plate 18 is pivotally connected to the base 19, and the other side is connected to the base 19 through a second telescopic device 20. The base 19 is generally placed horizontally and can also be connected to a robotic arm. By setting the second telescopic device 20, the deflection angle of the bottom plate 18 can be adjusted so that the grinding wheel 1 and the contour tooth 9 can be adaptively deflected. The deflection angle corresponds to the angle of the bevel gear to achieve grinding and support of the bevel gear.

[0033] In this embodiment, the telescopic support frame 3 includes an outer rod 21 and an inner rod 22 with one end slidably arranged in the outer rod 21. The inner rod 22 can adjust the extension length relative to the outer rod 21. The outer end of the inner rod 22 is the output end of the telescopic support frame 3. The outer rod 21 and the inner rod 22 are locked by a third locking member 23.

[0034] In this embodiment, the rotation drive assembly includes a driven wheel 24, a driving wheel 25, and a transmission belt 26. The center of the driven wheel 24 is connected to the transmission shaft 10, and the driven wheel 24 is connected to the driving wheel 25 through the transmission belt 26. The driving wheel 25 is driven to rotate by the motor 27. A vertical plate is fixed above the telescopic support frame 3, and the upper end of the vertical plate is hinged to one end of a rotating plate 29. The other end of the rotating plate 29 is connected to a tensioning wheel 30. The outer side of the tensioning wheel 30 abuts against the transmission belt 26. The rotating plate 29 is connected to the vertical plate through a third telescopic device 31. Transmission is carried out through a pulley, so that the output position of the rotating drive component can be adjusted to adapt to the extended length of the telescopic support frame 3, and there is no need to re-plan the output method of the rotating drive component, making its output more convenient. Similarly, the transmission belt 26 is tensioned by the tensioning wheel 30, and the third telescopic device 31 is used to adjust the tensioning position and degree. When the position of the grinding wheel 1 is changed, there is no need to change the specifications of the transmission belt 26, and the tensioning of the transmission belt 26 can be achieved, which makes adjustment more convenient and saves costs.

[0035] In this embodiment, the rotating drive assembly has two groups and is arranged on both sides of the grinding wheel 1. The driving wheels 25 of the two groups of rotating drive assemblies are connected by the same rotating shaft, and the rotating shaft is connected to the same motor 27, which can simplify the transmission structure. The rotating shaft is also connected to the bearing seat 32, making the overall transmission structure more stable.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
