[0010] By adopting the above technical solution, the setting of the second cylinder can cooperate with the bottom of the placement groove to clamp the shaft to be processed, so that the shaft to be processed can partially extend out of the placement groove. The mounting frame does not need to be too close to the grinder body to send the shaft to be processed between the grinding wheel and the guide wheel, making it less likely for interference between the mounting frame and the grinder body, thereby increasing the service life of the mounting frame.

[0011] Optionally, it also includes a material delivery component, which is arranged on one side of the mounting frame to deliver material into the placement groove. The material delivery component includes a fixed plate, a movable plate and a third cylinder.

The bracket 31 is installed on the oil collecting box 22, and the bracket 31 is arranged along the length direction of the base 21 to support other structures. The guide rail 32 is fixedly connected to the bracket 31, and the guide rail 32 is arranged along the length direction of the bracket 31. The sliding frame 33 is provided with a sliding groove 331 matching the guide rail 32, and the sliding groove 331 runs through both sides of the sliding frame 33. A part of the guide rail 32 is embedded and slides in the sliding groove 331, so that the sliding frame 33 is slidably connected to the guide rail 32 to approach or move away from the grinding machine body 1. A synchronous belt 311 is also installed on the bracket 31. A motor and a transmission roller that drive the synchronous belt 311 to rotate are fixedly connected to the bracket 31, which are not drawn in this figure. A driving block 332 is fixedly connected to the side of the sliding frame 33 close to the synchronous belt 311. The driving block 332 is meshed and clamped with the rack on the synchronous belt 311, so that the synchronous belt 311 drives the sliding frame 33 to slide along the length direction of the guide rail 32.

[0043] The fourth cylinder 37 is fixedly connected to the sliding frame 33 and the piston shaft is set downward. The mounting frame 34 is fixedly connected to the piston rod of the fourth cylinder 37. The mounting frame 34 slides on the sliding frame 33 in the vertical direction and is limited by the slide rail, so that the mounting frame 34 is not easy to interfere with the material delivery assembly 4 as the sliding frame 33 slides. The side of the mounting frame 34 away from the fourth cylinder 37 is horizontally arranged. The side of the mounting frame 34 away from the sliding frame 33 is provided with a placement groove 341. The placement groove 341 is arranged along the length direction of the bracket 31 and passes through the side of the mounting frame 34 close to the grinder body 1 for placing the shaft to be processed. The first cylinder 35 is fixedly connected to the side of the mounting frame 34 away from the grinder body 1. The first cylinder 35 is arranged along the length direction of the placement groove 341. The piston rod of the first cylinder 35 extends into the placement groove 341 to push the shaft to be processed in the placement groove 341 out of the placement groove 341 and into the grinder body 1.

[0044] The second cylinder 36 is fixedly connected to the sliding frame 33, and the piston rod of the second cylinder 36 is set toward the placement groove 341. An abutment column 361 is fixedly connected to the piston rod of the second cylinder 36. The abutment column 361 is located on the side of the placement groove 341 away from the first cylinder 35. The abutment column 361 abuts on the axis to be processed placed in the placement groove 341, so that the axis to be processed can partially extend out of the placement groove 341 without being completely placed in the placement groove 341.

[0045] A first sensor 312 is also installed on the bracket 31 . There are two first sensors 312 . Both first sensors 312 are located at two ends of one side of the synchronous belt 311 to sense the sliding frame 33 on the synchronous belt 311 .

[0046] When the shaft to be processed is placed in the placement groove 341, the second cylinder 36 drives the abutment column 361 to abut against the shaft to be processed, and then the fourth cylinder 37 drives the mounting frame 34 to move upward to avoid the material delivery assembly 4, and then the synchronous belt 311 drives the sliding frame 33 to approach the grinder body 1. When the sliding frame 33 reaches the corresponding position of the first sensor 312, the sliding frame 33 stops sliding, and then the first cylinder 35 pushes the shaft to be processed to fall between the grinding wheel and the guide wheel of the grinder body 1 for grinding.

[0047] Reference Figure 3 and Figure 4 The material delivery assembly 4 is installed on the bracket 31 so that the material feeding assembly 3 can continuously feed the material. The structure of the material delivery assembly 4 is as follows: the material delivery assembly 4 includes a fixed plate 41, a movable plate 42, a third cylinder 43, a material discharge plate 44, a material blocking plate 45, a material feeding plate 46 and a fifth cylinder 47.

[0048] Combination Figure 2The fixed plate 41 is mounted on the bracket 31. When the sliding frame 33 slides to the side away from the grinding machine body 1, the fixed plate 41 is located on the side of the mounting frame 34 close to the grinding machine body 1. There are two fixed plates 41, and the two fixed plates 41 are symmetrically arranged. The two fixed plates 41 are arranged perpendicular to the bracket 31. The upper side of the fixed plate 41 is provided with a first material transfer groove 411. There are several first material transfer grooves 411. Several first material transfer grooves 411 are arranged along the length direction of the fixed plate 41 and are arranged adjacent to each other so that the two ends of the axis to be processed can be embedded one by one. A guide surface 4111 is provided on the side of the first material transfer groove 411 away from the mounting frame 34, so that the side wall of the first material transfer groove 411 away from the mounting frame 34 is arranged to be inclined downward from the side away from the mounting frame 34 to the side close to the mounting frame 34, so as to guide the axis to be processed entering the first material transfer groove 411 to roll to the side close to the mounting frame 34. A second material transfer groove 412 is provided on the upper side of the fixed plate 41 near the mounting frame 34, so that the two ends of the axis to be processed can be inserted one by one, and the two ends of the axis to be processed extend through the second material transfer groove 412 to the opposite sides of the two fixed plates 41. When the sliding frame 33 slides to the side away from the grinding machine body 1, the second material transfer groove 412 and the placement groove 341 are coaxially arranged, so that the end of the axis to be processed placed in the second material transfer groove 412 near the placement groove 341 can be inserted into the placement groove 341. The third cylinder 43 is fixedly connected to the bracket 31 and is located on the lower side of the fixed plate 41. The piston rod of the third cylinder 43 is arranged upward, and a mounting block 431 is fixedly connected to the piston rod of the third cylinder 43. There are two movable plates 42, and the two movable plates 42 are fixedly connected to the two sides of the mounting block 431 to move up and down with the piston rod of the third cylinder 43. The two movable plates 42 are both located between the two fixed plates 41 and are arranged parallel to the fixed plates 41, so that when the movable plates 42 move upward, the axis to be processed located in the first material transfer groove 411 is pushed upward. The movable plate 42 is also provided with a movable groove 421 identical to the first material transfer groove 411, so that when the axis to be processed moves upward, it enters the adjacent first material transfer groove 411 on the side close to the mounting frame 34 under the guidance of the side wall of the movable groove 421. The bracket 31 is also provided with a first long waist hole 313, which is arranged in the vertical direction, and the number of the first long waist holes 313 is two. The fixed plate 41 is provided with a second long waist hole 413, which is arranged parallel to the first long waist hole 313. The movable plate 42 is fixedly connected with a sliding rod 432, and the two ends of the sliding rod 432 pass through the second long waist hole 413 and the first long waist hole 313 one by one and extend to the two ends, limiting the range of the upward and downward sliding of the movable plate 42.

[0049] The material discharge plate 44 is fixedly connected to the side of the fixed plate 41 away from the mounting frame 34 for placing the processing shaft. Baffles 441 are fixedly connected to both sides of the material discharge plate 44 so that the processing shafts can be piled up. The material discharge plate 44 is arranged to be tilted downward from the side away from the fixed plate 41 to the side away from the fixed plate 41, so that the shafts to be processed on the material discharge plate 44 all roll toward the side of the fixed plate 41. The baffle plate 45 is fixedly connected to the side of the fixed plate 41 away from the mounting frame 34, and the baffle plate 45 is located between the fixed plate 41 and the material discharge plate 44, so that the material on the material discharge plate 44 is not easy to enter the fixed plate 41.

[0050] The fifth cylinder 47 is fixedly connected to the bracket 31, and the fifth cylinder 47 is located at the lower side of the material discharge plate 44. The piston rod of the fifth cylinder 47 is arranged upward, and the feed plate 46 is fixedly connected to the piston rod of the fifth cylinder 47 to move up and down with the driving of the fifth cylinder 47. The material discharge plate 44 has a sliding hole 442, and the sliding hole 442 is located on the side of the material discharge plate 44 close to the material blocking plate 45, so that the feed plate 46 can slide up and down. The feed plate 46 has an embedding hole 461 for embedding and placing a shaft to be processed. The lower side wall of the embedding hole 461 is arranged in a plane parallel to the upper surface of the placement plate. When the feed plate 46 moves downward, the lower side wall of the embedding hole 461 and the upper surface of the placement plate are arranged in the same plane to guide a shaft to be processed into the embedding hole 461. When the feed plate 46 moves upward, the shaft to be processed entering the embedding hole 461 is matched by the baffle plate 45 and the lower side wall of the embedding hole 461 and is not easy to fall from the embedding hole 461 until the feed plate 46 rises to the position corresponding to the upper side wall of the baffle plate 45. The upper side wall of the baffle plate 45 is arranged downwardly from the side away from the fixed plate 41 to the side away from the fixed plate 41. Here, the upper side wall of the baffle plate 45 and the lower side wall of the embedding hole 461 are arranged in parallel, so that after rolling from the embedding hole 461 to the upper side wall of the baffle plate 45, it continues to roll into the first material delivery groove 411 of the fixed plate 41.

[0051] A second sensor 314 is also mounted on the bracket 31 . The second sensor 314 is located between the two fixing plates 41 and at the lower side of the second material transfer trough 412 to sense whether there is a shaft to be processed in the second material transfer trough 412 .

[0052] When the second sensor 314 senses that there is no axis to be processed in the second material transfer slot 412, the third cylinder 43 is driven to push the movable plate 42 upward, thereby driving the axis to be processed in each first material transfer slot 411 to the adjacent first material transfer slot 411, and then the axis to be processed in the first material transfer slot 411 adjacent to the second material transfer slot 412 enters the second material transfer slot 412 for replenishment. The fifth cylinder 47 pushes the feeding plate 46 upward to push the axis to be processed in the embedded hole 461 upward and then roll it to the first material transfer slot 411 close to the blocking plate 45.
