in operation, because the path of the mounting ring 9 when pushing the contact rod 30 and the support sliding plate 27 to move leftward is an arc with the rotating shaft 2 as the rotating center, the arc-shaped groove 28 and the support sliding plate 27 are both configured to be arc-shaped, and the arc-shaped groove 28 and the support sliding plate 27 are both concentric with the rotating shaft 2, so that when the mounting ring 9 pushes the contact rod 30 and the support sliding plate 27 to slide leftward, no relative displacement occurs between the mounting ring 9 and the contact rod 30 as well as between the mounting ring 9 and the support sliding plate 27, and the wear of the mounting ring 9 and the support sliding plate 27 is reduced.
As a further scheme of the invention, a lifting groove 34 is formed on the circumferential surface of the rotating cylinder 23, a sliding shaft is slidably mounted at the lower end of the inner cavity of the cooling liquid pool 1, a lifting rod 35 is fixedly mounted at the upper end of the sliding shaft, the rear end of the lifting rod 35 is slidably mounted in the lifting groove 34, a lower supporting ring 36 is fixedly mounted at the front end of the lifting rod 35, an upper supporting ring 37 is fixedly mounted at the lower end of the mounting shaft 5, and the lower supporting ring 36 is in contact with the lower end surface of the upper supporting ring 37 while being rotatably connected with the lower end of the mounting shaft 5;
as shown in fig. 2-3, during operation, the rotary drum 23 will rotate continuously, the lifting groove 34 of the rotary drum 23 will drive the lifting rod 35 to ascend or descend during rotation, and the mounting shaft 5 is slidably mounted at the rear end of the driving device 4, so that the upper supporting ring 37 at the lower end of the mounting shaft 5 can be supported by the lower supporting ring 36 at the front end of the lifting rod 35, and thus the lifting rod 35 can drive the mounting shaft 5 to ascend and descend synchronously during ascending and descending, and the rotation of the rotary shaft 2 and the ascending and descending of the mounting shaft 5 are linked, so that the overall operation is more continuous.
As a further scheme of the invention, a boss is fixedly mounted at the rear end of the mounting frame 26, a tray 38 is fixedly mounted at the upper end of the boss, a rotating rod 39 is rotatably mounted in the middle of the boss, a blanking disc 40 is fixedly mounted at the upper end of the rotating rod 39, a plurality of blanking slots 41 are formed in the blanking disc 40, a blanking hole 42 is formed in the leftmost end of the tray 38, a blanking barrel is arranged at the upper end of the blanking disc 40, and the rotating rod 39 and the rotating shaft 2 are in transmission through a chain;
as shown in fig. 8-9, in operation, a worker can directly stack gears in the feed cylinder, because the lower end of the rotating rod 39 is in transmission with the rotating shaft 2 through a chain, the rotating rod 39 also rotates when the rotating shaft 2 rotates, the rotating rod 39 rotates to drive the feed tray 40 above the rotating rod to rotate, when the feed tank 41 rotates to the position below the feed cylinder, the gears in the feed cylinder fall into the feed tank 41, then the feed tray 40 rotates to drive the gears in the feed tank 41 to rotate, when the feed tank 41 rotates to be aligned with the feed holes 42, the gears in the feed tank 41 pass through the feed holes 42 and fall into the positioning grooves 11 below, the worker only needs to place the stacked gears in the feed cylinder, and does not need to place one gear into the positioning grooves 11, which further facilitates the operation of the worker.
As a further scheme of the present invention, a lifting inclined plane 43 for lifting the mounting block 7 is fixedly mounted at the rear end of the mounting frame 26, and a return spring 44 is fixedly mounted at one end of the stopper 13 facing the inner side of the mounting groove 12;
as shown in fig. 10, in operation, since the mounting block 7 descends after being separated from the mounting frame 26 and the supporting sliding plate 27, when the mounting block 7 rotates to the mounting frame 26 again, the mounting block 7 needs to be lifted upwards to reset, a lifting inclined plane 43 is installed at the large rear end of the mounting frame 26, the lifting inclined plane 43 can lift and reset the descending mounting block 7, when the mounting block 7 is lifted and reset, the pressing gear 17 rotates counterclockwise, the pressing rack 15 rises in the mounting groove 12, as shown in fig. 6, then the return spring 44 pushes the stopper 13 to extend out of the mounting groove 12, so that the stopper 13 resets, and the mounting block 7 and the stopper 13 do not need to be manually reset by an operator, so that the whole device is simpler and more convenient to use.
