The push plate 52 is arranged along the vertical direction, and one side of the push plate 52, which is far away from the sixth cylinder 51, extends into the space between the grinding wheel and the guide wheel of the grinding machine body 1 so as to push the processed shaft entering the space between the grinding wheel and the guide wheel of the grinding machine body 1 out of the grinding machine body 1.

Referring to fig. 2, a belt 53 is fixedly attached to the support 31, the belt 53 is driven by a motor, the belt 53 is disposed in parallel with the guide rail 32, and the belt 53 is disposed on the lower side of the carriage 33 such that the position of the belt 53 is aligned with the gap between the grinding wheel and the guide wheel of the grinding machine body 1. One end of the conveyor belt 53 extends to the side wall of the grinding machine body 1 away from the sixth cylinder 51, so that the processed shaft pushed out by the push plate 52 enters the conveyor belt 53 and moves to the side away from the grinding machine body 1.

In order to prevent the processed shaft from being separated from the conveyor belt 53, two barrier strips 315 are fixedly connected to the bracket 31, and the two barrier strips 315 are located at two sides of the conveyor belt 53 to block the processed shaft on the conveyor belt 53. One side of the barrier strip 315 far away from the bracket 31 is fixedly connected with a guide plate 316, the guide plate 316 is located on one side of the barrier strip 315 close to the grinding machine body 1, and the upper surface of the guide plate 316 is inclined and arranged downwards from one side far away from the barrier strip 315 to one side close to the barrier strip 315, so that a processed shaft pushed out by the push plate 52 enters between the two barrier strips 315 along the direction of the guide plate 316.

The material blocking block 54 is installed on one side, far away from the grinding machine body 1, of the conveyor belt 53, and the material blocking block 54 and the conveyor belt 53 are obliquely arranged in the length direction so as to block a processed shaft on the conveyor belt 53 out of the conveyor belt 53. The storage box 55 is fixedly connected to one side of the conveyor belt 53, and the material blocking block 54 extends onto the storage box 55, so that the processed shaft pushed out by the material blocking block 54 enters the storage box 55 for storage.

The implementation principle of the full-automatic centerless cylindrical grinder in the embodiment of the application is as follows: the shaft to be processed on the material placing plate 44 enters the embedding hole 461, the fifth cylinder 47 pushes the material feeding plate 46 to move upwards to push the shaft to be processed in the embedding hole 461 upwards and then roll to the first material passing groove 411 close to the material blocking plate 45, the third cylinder 43 is driven to push the movable plate 42 upwards to drive the shaft to be processed in each first material passing groove 411 to be processed in the adjacent first material passing groove 411, then the shaft to be processed in the first material passing groove 411 adjacent to the second material passing groove 412 enters the second material passing groove 412, and one end of the shaft to be processed enters the placing groove 341; the second cylinder 36 orders about the butt column 361 butt on waiting to process epaxial, then the fourth cylinder 37 orders about the mounting bracket 34 and shifts up and avoid passing the material subassembly 4, then hold-in range 311 drives the slip frame 33 and be close to grinding machine body 1, when the slip frame 33 reachs the first sensor 312 corresponding position, the slip frame 33 stops sliding, then first cylinder 35 promotes waiting to process the axle and fall into grinding machine body 1's emery wheel and guide pulley between polish, after finishing polishing, sixth cylinder 51 orders about push pedal 52 and pushes away to the conveyer belt 53 with the axle that has processed, then the axle that has processed is kept off on the conveyer belt 53 at the material blocking piece 54 and is gone into in the receiver 55 and accomodate.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
