[0002] A gear shaft refers to a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. It simplifies the transmission mechanism by combining the functions of the gear and the shaft into one. It is generally in the shape of a metal round rod, and each section can have a different diameter.

[0003] During the gear shaft processing, the gear groove is first cut out using cutting methods such as hobbing and gear shaping to form a blank with a rough gear contour. The cut gear groove is then precision ground using a gear grinder. The gear grinder can effectively correct the errors generated in the early cutting process and improve the accuracy of the gear shaft.

[0004] When using a gear grinder to process a gear shaft, first place the gear shaft in a fixture, then start the gear grinder to grind the gear shaft.

[0035] Combined with Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 7 , Attachment Fig.10 , Attachment Fig.11As shown, the adjustment mechanism 8 includes a plug column 81 movably plugged into the workbench 1, one end of the plug column 81 is provided with a connecting ring 82, the other end of the plug column 81 abuts against the bottom surface of the gear 1 61, the connecting ring 82 is provided with two connecting plates 83, the connecting plate 83 is provided with a slide groove 1 84, the bottom surface of the workbench 1 is hinged with a connecting rod 2 85, and a torsion spring 86 is provided between the connecting rod 2 85 and the workbench 1, one end of the connecting rod 2 85 is provided with a sliding shaft 87, and the sliding shaft 87 is located in the slide groove 1 84, the workbench 1 A plug plate 88 is movably connected to the platform 1, and a plug hole 89 is provided on the plug plate 88. A push rod 810 is provided on the grinding mechanism 4. The push rod 810 is arranged on one side of the slide 42. A driving block 811 that cooperates with the plug hole 89 is provided on the push rod 810.

[0036] Working principle: when the gear grinding mechanism 4 is not in the gear grinding position, the torsion spring 86 is in a tensioned state, and the gear 1 61 on the rotating shaft 5 is meshed with the gear 2 62. When the gear grinding mechanism 4 is in the gear grinding position, the driving block 811 is away from the insertion hole 89, and the torsion spring 86 drives the connecting rod 2 85 to rotate. At this time, the connecting rod 2 85 close to one end of the turntable 2 is upward, and through the setting of the extension plate 812, the sliding hole 813, the second slide groove 814, and the sliding column 815, one end of the plug plate 88 is slidably connected with the connecting rod 2 85, so that the other end of the connecting rod 2 85 rotates to drive the plug plate 88 to move downward, and through With the arrangement of the sliding shaft 87 and the slide groove 84, the connecting rod 2 85 rotates upward to drive the connecting ring 82 to move upward, and the connecting ring 82 pushes the gear 1 61 to move upward, and the gear 1 61 moves up and meshes with the gear 3 74. When the grinding mechanism 4 completes the grinding and moves away from the grinding station, the driving block 811 is inserted into the socket 89, and the plug plate 88 moves up. The upward movement of the plug plate 88 drives one end of the connecting rod 2 85 to move up, and the connecting rod 2 85 located at one end of the turntable 2 moves down. Under the action of gravity, the gear 1 61 is always in contact with the plug column 81, thereby following the plug column 81 to move downward, and the gear 1 61 moves down and meshes with the gear 2 62.

[0037] Combined with Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 8 As shown, the rotating column 3 is provided with a fixing mechanism 32 for fixing the gear shaft 21, and the fixing mechanism 32 includes a plurality of clamping blocks 33 hinged on the rotating column 3, and an external threaded barrel 34 is rotatably provided on the rotating column 3, and a threaded ring 35 is threadedly connected to the external threaded barrel 34, and a plurality of connecting rods 36 are hinged on the threaded ring 35, and the other end of the connecting rod 36 is hinged to the clamping block 33, and a toggle ring 37 is provided at one end of the external threaded barrel 34, and a limiting column 38 penetrating the threaded ring 35 is provided on the bottom surface of the rotating column 3.

[0038] The working principle of the fixing mechanism 32 is as follows: the toggle ring 37 is rotated, the toggle ring 37 drives the external threaded tube 34 to rotate, the rotation of the external threaded tube 34 causes the threaded ring 35 to move upward, the upward movement of the threaded ring 35 drives the connecting rod 1 36 to rotate, and the connecting rod 1 36 drives the clamping block 33 to clamp the gear shaft 21 on the rotating column 3.

The control mechanism 11 includes a fixed column 12 arranged on the workbench 1, a fixed ring 13 is provided on the fixed column 12, a top column 14 abutting against the fixed ring 13 is provided on the gear three 74, and an arc-shaped inclined surface 15 is provided on the fixed ring 13 at the gear grinding station.

[0040] Working principle of control mechanism 11: In the initial state, spring 73 is in a compressed state. When rotating column 3 is on arc slope 15, spring 73 pushes rotating shaft 72 to move downward, so that top column 14 on gear three 74 is against arc slope 15, and gear three 74 moves downward so as to engage with gear one 61, thereby realizing that only rotating column 3 located at the gear grinding station rotates.

[0041] Combined with Figure 5 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig.11 As shown, a sliding groove 91 is provided on the workbench 1 at the rotating shaft 5, a fixed gear 92 is provided on the plug column 81, a limit block 93 is provided on the gear three 74, and a limit groove cooperating with the limit block 93 is provided on the bottom surface of the turntable 2. When the rotating shaft 5 drives the turntable 2 to rotate, the fixed gear 92 is located in the sliding groove 91 and does not play a role in limiting the position of the gear two 62. The gear three 74 located above the fixed ring 13 cannot rotate under the action of the limit block 93 and the limit groove. The gear three 74 located above the arc-shaped inclined surface 15 moves downward, so that the limit block 93 is away from the limit groove and can rotate. When the rotating shaft 5 drives the gear three 74 to rotate, the plug column 81 pushes the gear one 61 to mesh with the gear three 74, and the fixed gear 92 moves up to mesh with the gear two 62 to limit the turntable 2.

[0042] In specific use, the gear shaft 21 is placed on the limiting groove 31 on the rotating column 3, and then the gear shaft 21 is fixed by the fixing mechanism 32. The motor drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the turntable 2 to rotate through the rotating mechanism 6. Then the gear shafts 21 are placed and fixed in sequence. When the first gear shaft 21 reaches the gear grinding station, the gear grinding mechanism 4 is started, and the gear grinding mechanism 4 moves to drive the adjusting mechanism 8. The adjusting mechanism 8 makes the rotating shaft 5 drive the turntable 2 to rotate instead of driving the rotating column 3. Then the gear grinding mechanism 4 adjusts the tooth grooves on the gear shaft 21. Gear grinding, when one tooth groove is ground, the rotating shaft 5 rotates to drive the rotating mechanism 2 7, and the rotating mechanism 2 7 drives the rotating column 3 to rotate, so as to continue grinding the other tooth grooves. After processing one gear shaft 21, the gear grinding mechanism 4 moves away from the gear grinding station, and the gear grinding mechanism 4 drives the adjusting mechanism 8. The adjusting mechanism 8 allows the rotating shaft 5 to drive the rotating column 3 to rotate and then drive the turntable 2 to rotate, so as to replace the gear shaft 21, saving the time for replacing the gear shaft 21 and unloading, and the gear shaft 21 can be loaded and unloaded when it is being processed, thereby improving the processing efficiency.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
