[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4 As shown, a high-efficiency feeding device for gear processing comprises a processing table 1, a lifting seat 2 is movably installed at the center of the upper end surface of the processing table 1, symmetrically arranged mounting blocks 4 are fixedly installed on the outer walls of both sides of the processing table 1, and a driving gear 3 is rotatably installed on the mounting blocks 4, a rotating rod 6 is fixedly installed at the center of the outer wall of the driving gear 3, a clamping block 8 is fixedly installed at the end of the rotating rod 6, the cross section of the clamping block 8 is L-shaped, and a positioning component is arranged inside the clamping block 8, wherein a plurality of mounting holes are opened on the upper end surface of the processing table 1 on the peripheral side of the lifting seat 2, and a buffer component is arranged inside the plurality of mounting holes;

[0025] Two groups of symmetrical clamping blocks 8 arranged on both sides of the processing table 1 can respectively clamp large gears and load them onto the processing table 1 for processing, and clamp large gears that have been processed on the lifting seat 2 for unloading. When the driving gear 3 on one side of the processing table 1 rotates, the rotating rod 6 fixedly connected to the driving gear 3 rotates synchronously. The end of the rotating rod 6 is fixedly connected to a clamping block 8, and the rotating rod 6 and the clamping block 8 are perpendicular to each other. When the rotating rod 6 flips 180 degrees, the clamping block 8 arranged at the end of the rotating rod 6 is parallel to the ground. At this time, the clamping block 8 can be arranged on both sides of the large gear to be processed. The two clamping blocks 8 can clamp the large gear. The two groups of clamping blocks 8 arranged on both sides of the processing table 1 can alternately perform loading and unloading operations on the processing table 1, thereby improving the processing efficiency of the processing table 1 for gears.

[0026] like Figure 1 As shown, the positioning assembly includes multiple return springs 11, one end of the return spring 11 is fixedly connected to the inner wall of the clamping block 8, and the other ends of the multiple return springs 11 are commonly connected to the arc block 12; when the large gear is clamped, in the process of flipping the clamping block 8 to place the large gear on the upper surface of the processing table 1 or removing the large gear from the upper surface of the processing table 1, when the clamping block 8 is flipped to both sides of the upper end surface of the processing table 1, the arc surface of the arc block 12 arranged inside the clamping block 8 and the protrusion of the upper end surface of the processing table 1 are squeezed, then when the arc block 12 is squeezed, the multiple return springs 11 fixedly connected to the arc block 12 can synchronously make adaptive deformation, then under the action of the arc block 12, it can avoid the end of the clamping block 8 away from the rotating rod 6 from approaching each other, thereby causing the large gear to be placed on the upper surface of the processing table 1. Inaccurate position.

[0027] like Figure 4 As shown, the buffer assembly includes a gas spring 10 fixedly installed inside the mounting hole, and the upper end of the gas spring 10 is rotatably connected to a buffer support block 9. When any position of the buffer support block 9 is squeezed, the inclination angle of the buffer support block 9 can be adaptively adjusted, thereby making the buffer support block 9 fit the outer wall of the large gear to be processed.

[0028] like Figure 4 As shown, the buffer support block 9 is arranged in a fan ring shape, and multiple buffer support blocks 9 are combined into a circular ring; multiple fan ring-shaped buffer support blocks 9 are combined and surrounded on the circumference of the lifting seat 2, thereby ensuring the buffering effect of the large gear to be processed during the process of placing the end surface on the processing table 1.

[0029] like Figure 2As shown, a synchronous belt 5 is arranged between the two driving gears 3 arranged on the same side of the processing table 1, and the two ends of the synchronous belt 5 are respectively meshed and connected with the two driving gears 3; under the action of the synchronous belt 5, when one of the driving gears 3 rotates under the drive of external force, the other driving gear 3 can rotate synchronously, so that the two groups drive the two groups of clamping blocks 8 arranged on both sides of the processing table 1 to alternately clamp the large gear, so that the unloading of the large gear after processing and the loading of the unprocessed large gear can be carried out synchronously.

[0030] like Figure 1 As shown, electric telescopic rods 7 are fixedly installed on the outer walls of the opposite sides of the two clamping blocks 8, and rubber blocks 13 are fixedly installed on the output ends of the electric telescopic rods 7; after the electric telescopic rods 7 are extended, they can squeeze the outer wall of the large gear, and then clamp and fix the large gear. The rubber block 13 arranged at the end of the electric telescopic rod 7 can, on the one hand, prevent the end of the electric telescopic rod 7 from squeezing the outer wall of the large gear and causing damage to its outer wall, and on the other hand, increase the friction between the end of the electric telescopic rod 7 and the large gear to be processed.

[0031] like Figure 1 As shown, the number of the electric telescopic rods 7 is not less than three groups, and the rubber block 13 arranged at the end of the electric telescopic rod 7 is elastically arranged; the multiple electric telescopic rods 7 on the two clamping blocks 8 change according to the shape of the large gear until the ends of the multiple electric telescopic rods 7 are against the outer wall of the large gear to be processed, wherein the rubber block 13 arranged at the end of the electric telescopic rod 7 can be elastically deformed accordingly, and the more the number of electric telescopic rods 7 is, the more contact points there are with the outer wall of the large gear to be processed, and the large gear can be clamped more stably.

[0032] The working principle of the utility model is as follows: when in use, two groups of symmetrical clamping blocks 8 arranged on both sides of the processing table 1 can respectively clamp large gears to be loaded onto the processing table 1 for processing, and clamp large gears that have been processed on the lifting seat 2 for unloading. When the driving gear 3 on one side of the processing table 1 rotates, the rotating rod 6 fixedly connected to the driving gear 3 rotates synchronously, and the clamping block 8 is fixedly connected to the end of the rotating rod 6, and the rotating rod 6 and the clamping block 8 are perpendicular to each other. When the rotating rod 6 is turned over 180 degrees, the clamping block 8 arranged at the end of the rotating rod 6 is parallel to the ground. At this time, the clamping blocks 8 can be arranged on both sides of the large gear to be processed, and the multiple electric telescopic rods 7 on the two clamping blocks 8 change according to the shape of the large gear until the ends of the multiple electric telescopic rods 7 abut against the outer wall of the large gear to be processed, wherein the rubber blocks 13 arranged at the ends of the electric telescopic rods 7 can be elastically deformed accordingly. After the multiple electric telescopic rods 7 stably clamp the outer walls of the large gear to be processed respectively, the driving gear 3 rotates under the driving of an external force, so that the rotating rod 6 turns 180 degrees and places the large gear to be processed on the upper surface of the processing table 1. When placing the large gear to be processed on the upper surface of the processing table 1, the large gear to be processed can preferentially contact one of the buffer support blocks 9, and the bottom surface of the buffer support block 9 is rotatably connected to the upper end surface of the gas spring 10, so the buffer support block 9 can be adaptively changed synchronously when contacting the large gear. In the process of gradually placing the large gear on the upper surface of the processing table 1, the multiple gas springs 10 and the buffer support block 9 cooperate with each other to buffer the process of placing the large gear. When the large gear to be processed is completely placed on the upper surface of the processing table 1, the lifting seat 2 is lifted upward to The large gear to be processed is lifted, which makes it easier to perform drilling or gear grinding on other existing structures on the processing table 1. In this process, after the large gear to be processed is processed, the driving gear 3 rotates again. At this time, under the action of the synchronous belt 5, a group of clamping blocks 8 located on the other side of the processing table 1 can be flipped to clamp the processed large gear. In the process of continuous forward or reverse rotation of the driving gear 3, the two groups of clamping blocks 8 can alternately load and unload materials on the processing table 1, thereby improving the processing efficiency of the processing table 1 for gears.
