[0030] Please refer to Figure 1-8 , the present invention provides a technical solution: an intelligent tooling for processing transmission gears, including a base 1, a four-jaw chuck 2 is rotatably connected to the upper end of the base 1, a support rod 3 is clamped and fixed to the upper end of the four-jaw chuck 2, a support block 4 is fixedly connected to the upper end of the support rod 3, a fixed cylinder 12 is fixedly connected to the upper end of the support block 4, and an automatic alignment mechanism is arranged on the fixed cylinder 12. The automatic alignment mechanism is used for automatically aligning the gear to be processed after sleeving it on the fixed cylinder 12, so that the gear to be processed and the fixed cylinder 12 are in a concentric position and remain fixed;

[0031] When the above solution is put into actual use, the gear raw material processed according to the size is taken off from the lathe, a support rod 3 of a suitable size is selected according to the inner diameter of the gear to be processed and placed on the upper end of the four-jaw chuck 2, the four-jaw chuck 2 is started to clamp and fix the support rod 3. After fixing, the gear to be processed is placed on the upper end of the support block 4, the automatic alignment mechanism is sleeved on the fixed cylinder 12 and slides downwards, and the gear to be processed placed on the support block 4 is compacted and fixed on the upper end of the support block 4, and during the compaction process, the gear to be processed and the fixed cylinder 12 are kept in a concentric position. According to the requirements of gear processing, a corresponding hobbing gear is selected and installed on the hobbing machine table on one side of the base 1, and the inclination angle of the hobbing gear is adjusted according to the gear requirements. The driving motor inside the base 1 is started to drive the four-jaw chuck 2 to rotate, so that the gear to be processed on the support block 4 contacts the hobbing gear and is ground into shape. After grinding, the automatic alignment mechanism is loosened and removed from the support rod 3, and then the processed gear can be taken off from the support rod 3 for further processing. The present invention adopts an automatic alignment mechanism, which can synchronously perform the fixing and alignment processing of the gear to be processed. When the gear to be processed is fixed on the support rod 3, the gear to be processed and the support rod 3 are kept in a concentric position at the same time, which can greatly improve the processing efficiency and also improve the accuracy during processing.

[0032] As a further solution of the present invention, the automatic positioning component includes a fixing ring 10, which is slidably sleeved on a fixing cylinder 12, a connecting ring 6 is arranged below the fixing ring 10, and a plurality of connecting shafts 8 equidistantly distributed are fixedly connected to the upper end of the connecting ring 6, and the upper end of the connecting shaft 8 slides through the fixing ring 10 and is arranged on the upper side of the fixing ring 10, a first spring 7 is fixedly connected to the bottom end of the connecting ring 6, and a clamping ring 5 is fixedly connected to the bottom end of the first spring 7, and a fixing frame 13 is fixedly connected to the upper end of the connecting ring 6, and a cone block 16 is slidably connected to one end of the fixing frame 13, and a shifting block 15 is fixedly connected to the upper end of the cone block 16, and the shifting block 15 is slidably arranged inside the fixing frame 13, and a second spring 14 for resetting the cone block 16 is fixedly connected to one end of the cone block 16, and a plurality of equidistantly distributed card slots 17 are opened on one side of the fixing cylinder 12, and a concentric shifting assembly is arranged inside the fixing cylinder 12, and the concentric shifting assembly is used to keep the gear to be processed and the fixing cylinder 12 in a concentric position;

[0033] When the above scheme is put into actual use, after the gear raw material with processed inner and outer diameters is placed on the upper end of the support block 4, when the gear raw material is fixed, the fixing ring 10 is sleeved on the outside of the fixing cylinder 12 and slides downward. During the sliding process of the fixing ring 10, the concentric toggle assembly is driven to extend from the inside of the fixing cylinder 12 to contact the inner diameter of the gear to be processed, and to press against the inner wall of the gear to be processed to keep it in a position concentric with the fixing cylinder 12. After the gear to be processed and the fixing cylinder 12 are kept concentric, the fixing ring 10 is fixed on the fixing cylinder 12, and then the connecting ring 6 is pushed to continue to slide downward so that the bottom end of the clamping ring 5 contacts the upper end surface of the gear and is gradually compressed. When the connecting ring 6 slides down, the cone block 16 at the upper end thereof is inserted into the fixing cylinder Inside the slot 17 on one side of 12, due to the inclined surface of the side wall of the cone block 16 and the action of the second spring 14, the cone block 16 can slide down along the slot 17 when the connecting ring 6 slides down. When the clamping ring 5 completely fixes the gear, the connecting ring 6 is released. Due to the elastic force of the first spring 7, the connecting ring 6 tends to slide upward, but because the cone block 16 is inserted into the inside of the slot 17, the position of the connecting ring 6 is fixed. At this time, the concentric alignment and fixation of the gear to be processed can be completed, that is, the gear is fixed at the upper end of the fixed cylinder 12, and then the gear rolling process can be performed. Through such an alignment method, not only the fixing effect is firm, but also the concentric processing effect of the gear and the fixed cylinder 12 through the concentric toggle assembly is also very precise.

[0034] As a further solution of the present invention, the concentric toggle assembly includes a turntable 22, which is rotatably arranged inside the fixed cylinder 12, and a plurality of equally spaced arc grooves 21 are provided on the turntable 22, and a plurality of equally spaced push rods 24 are equidistantly slidably connected inside the fixed cylinder 12, and one end of the push rod 24 can slide through the fixed cylinder 12, and a plurality of push rods 24 are fixedly connected to one side of their upper ends respectively, and the push rods 23 are slidably arranged inside the arc groove 21, and a positioning column 18 is fixedly connected to the top of the turntable 22, and a plurality of equally spaced threaded grooves 19 are provided on the positioning column 18, and a toggle ring 9 is fixedly connected to the inside of the fixed ring 10, and a connecting block is fixedly connected to the inner wall of the toggle ring 9, and a sliding groove 20 docking with the toggle ring 9 is provided on one side of the fixed cylinder 12;

[0035] When the above scheme is put into practical use, when the fixing ring 10 is slid down to the concentric processing of the gear to be processed and the fixing cylinder 12, the fixing ring 10 drives the toggle ring 9 to slide down synchronously, and the connecting block on the inner wall of the toggle ring 9 slides down along the threaded groove 19 on the outer wall of the alignment column 18, driving the alignment column 18 to rotate. When the alignment column 18 rotates, it drives the turntable 22 at the bottom to rotate synchronously. During the rotation of the turntable 22, the protrusion 23 slides along the arc groove 21, so that the push rod 24 extends to the outside of the fixing cylinder 12 along the protrusion 23. The extended fixing cylinder 12 will gradually contact the inner wall of the gear. When several fixing cylinders 12 are in contact with the inner wall of the gear, When in contact, since the extended lengths of several fixing tubes 12 are fixed, the gear can be fixed to a position concentric with the fixing tube 12. At this time, the fixing ring 10 cannot continue to slide downward, and the fixing ring 10 is fixed on the surface of the fixing tube 12. The connecting ring 6 continues to slide down to compact and fix the gear through the clamping ring 5. At this time, the positioning and fixing of the gear can be completed. The advantage of this is that there is no limit to the extended length of the push rod 24, that is, when facing gears of different sizes, the push rod 24 can contact the inner wall of the gear to fix the gear, so that a good positioning effect can be achieved when positioning gears of different sizes.

[0036] As a further solution of the present invention, one end of the fixing ring 10 is spirally connected to a threaded rod 11, and one end of the threaded rod 11 can be spirally passed through the fixing ring 10 and fit into the outer wall of the fixing tube 12;

[0037] When the above scheme is put into actual use, when the fixing ring 10 slides down to the position where the top rod 24 can make the gear concentric with the fixing tube 12 and cannot slide down further, the fixing ring 10 can be fixed to the fixing tube 12 by tightening the threaded rod 11. The fixing effect by the threaded rod 11 is strong enough and is very convenient to adjust.

[0038] As a further solution of the present invention, a waste frame 26 is slidably sleeved on the upper end of the base 1, and a docking port 27 for docking with the four-jaw chuck 2 is provided inside the waste frame 26, and the outer wall section of the docking port 27 is an inclined surface;

[0039] When the above scheme is put into actual use, a lot of debris will be generated during the gear tooth hobbing process. If these debris are not collected, it will be very troublesome to clean them up later. The debris generated by the gear hobbing can be effectively collected by the waste frame 26. The waste frame 26 can be removed from the upper end of the base 1, making it very convenient to handle the waste during the gear hobbing process.

[0040] As a further solution of the present invention, a plurality of rollers 25 equidistantly distributed are rotatably arranged at the upper end of the support block 4, and a third spring for resetting the rollers 25 is fixedly connected to the bottom end of the rollers 25;

[0041] When the above scheme is put into actual use, when the gear is placed on the upper end of the support block 4, the bottom end of the gear will preferentially contact the roller 25, so that when the gear and the fixed cylinder 12 are concentrically aligned, the gear can roll on the upper end of the roller 25. This has less friction than sliding directly on the upper end of the support block 4, and is more convenient for adjusting the position of the gear. The third spring allows the roller 25 to be retracted into the upper end of the support block 4, so that when squeezed and fixed, the sliding friction between the gear and the support block 4 replaces the rolling friction with the roller 25, thereby increasing the friction at the bottom end of the gear and enhancing the fixing effect.

[0042] As a further solution of the present invention, a driving motor is fixedly connected inside the base 1, and an output end of the driving motor is fixedly connected to the four-jaw chuck 2;

[0043] When the above solution is put into practical use, the four-jaw chuck 2 is driven to rotate by the driving motor, so that the gear can rotate to perform gear hobbing on the circumference of the gear during gear hobbing.

[0045] Step 1: Select a support rod 3 of appropriate size according to the inner diameter of the gear to be processed and place it on the upper end of the four-jaw chuck 2, start the four-jaw chuck 2 to clamp and fix the support rod 3, and after fixing it, place the gear to be processed on the upper end of the support block 4;

[0046] Step 2: Sleeve the automatic alignment mechanism on the fixed cylinder 12 and slide it downward to compact and fix the gear to be processed placed on the support block 4 to the upper end of the support block 4, and keep the gear to be processed and the fixed cylinder 12 in a concentric position during the compaction process;

[0047] Step 3: Start the drive motor inside the base 1 to drive the four-jaw chuck 2 to rotate, so that the gear to be processed on the support block 4 contacts the hob gear and is ground into shape;

[0048] Step 4: After the processing is completed, remove the automatic alignment mechanism from the fixed cylinder 12 and remove the processed gear.

Slide the automatic alignment mechanism downward after sleeving it on the fixed cylinder 12 to press and fix the gear to be processed placed on the support block 4 on the upper end of the support block 4, and keep the gear to be processed and the fixed cylinder 12 concentric during the pressing process. Select the corresponding hob gear according to the requirements of gear processing and install it on the hobbing machine table on one side of the base 1, and adjust the inclination angle of the hob gear according to the gear requirements. Start the drive motor inside the base 1 to drive the four-jaw chuck 2 to rotate, so that the gear to be processed on the support block 4 contacts the hob gear and is ground into shape. After grinding, loosen and remove the automatic alignment mechanism from the support rod 3, and then the processed gear can be removed from the support rod 3 for further processing.
