[0025] Specifically, four conveying claw hooks 33 are evenly distributed on the conveying chain 32 .

[0026] Specifically, a material unloading mechanism 5 is also provided on the frame 1, and the material unloading mechanism 5 includes a third cylinder 51 and a material unloading plate 53. The third cylinder 51 is arranged on the frame 1 on one side of the conveying mechanism 3, and a material unloading push plate 52 is fixedly connected to the output shaft of the third cylinder 51. The material unloading plate 53 is obliquely arranged on one side of the third cylinder 51 and is located below the moving path of the conveying claw hook 33.

[0027] In the above embodiment, the small end of the pin to be drilled is placed downward on the conveyor belt 21 in the material guide channel, the first motor 23 drives the conveyor belt 21 to work and drives the pin located in the material guide channel to move toward the discharge port 221 so that the pins are placed side by side in the material guide channel, and the front end of the pin is located at the discharge port 221. At the same time, the second motor 34 drives the conveyor chain 32 to move and drives the conveying claw hook 33 to move. In the process of moving the conveying claw hook 33 above the discharge port 221, the small end of the pin at the front end is stuck in the claw hook opening of the conveying claw hook 33, and the large end of the pin is against the conveyor. The upper end surface of the feeding claw hook 33 keeps the pin shaft in the transmission claw hook 33 and moves with the transmission claw hook 33. The frontmost pin shaft leaves the material guide channel through the discharge port 221 under the drive of the transmission claw hook 33. After the frontmost pin shaft leaves the material guide channel, the conveyor belt 21 drives the pin shaft in the material guide channel to move forward and moves the next pin shaft to the discharge port 221, so as to realize continuous feeding of the pin shaft when the next feeding claw hook moves above the discharge port 221, and the pin shaft kept in the transmission claw hook 33 moves with the transmission claw hook 33 to the position where the transmission claw hook 33 is aligned with the positioning seat 42 up and down. Then the first cylinder 45 drives the lifting plate 41 to rise so that the positioning seat 42 is tightly against the lower end of the pin shaft, and cooperates with the mounting plate 31 to fix the pin shaft. Then the second cylinder 46 drives the third motor 43 to move toward the pin shaft. At the same time, the third motor 43 drives the boring tool 44 to rotate, and cooperates with the movement of the third motor 43 to drill a retaining ring hole on the pin shaft to achieve the drilling operation of the pin shaft. After the drilling is completed and the third motor 43 and the lifting plate 41 are reset, the transmission claw hook 33 drives the pin shaft that has completed the drilling to continue to move to the side of the unloading push plate 52, and the third cylinder 51 drives the push plate to move toward the pin shaft that has completed the drilling. The pin is pushed out of the conveying claw hook 33 and falls onto the unloading plate 53, so as to realize the unloading of the pin with completed drilling. In the above manner, the loading mechanism 2 continuously conveys the pin to be drilled to the conveying mechanism 3, and the conveying mechanism 3 continuously conveys the pin to be drilled to the drilling mechanism 4, and the drilling mechanism 4 drills the pin and continuously conveys the pin with completed drilling to the unloading mechanism 5, and the unloading mechanism 5 realizes the unloading of the pin, thereby realizing the automation of the pin drilling operation, reducing the degree of manual participation in the pin drilling operation, saving manpower, and improving production efficiency.

[0028] Preferably, a baffle plate 222 made of a flexible material is provided in the discharge port 221. The baffle plate 222 limits the pin located at the discharge port 221 to prevent the pin from falling out of the material guide channel by itself, and provides a moving force when the pin is inserted into the conveying claw hook 33, so that the pin can be smoothly inserted into the conveying claw hook 33. When the conveying claw hook 33 drives the pin through the discharge port 221, the baffle plate 222 made of a flexible material is deformed under the action of the force so that the pin can pass through the discharge port 221. Specifically, the baffle plate 222 is made of rubber material.

[0029] Preferably, a guide rod 331 is fixedly connected to the conveying claw hook 33, and a guide groove 311 is opened on the mounting plate 31 along the moving path of the guide rod 331 with the conveying claw hook 33 and matching the guide rod 331. The guide rod 331 is placed in the guide groove 311. When the conveying claw hook 33 moves with the conveying chain 32 to convey the pin shaft, the guide rod 331 remains in the guide groove 311 and cooperates with the guide groove 311 to provide a guiding effect for the movement of the conveying claw hook 33, thereby ensuring the accuracy of the moving path of the conveying claw hook 33, thereby ensuring the accuracy of the conveying claw hook 33 when conveying the pin shaft, and ensuring that the pin shaft can be accurately moved to the drilling mechanism 4 and the unloading mechanism 5.

[0030] Preferably, the upper end of the guide rod 331 is fixedly connected to a limit block 332 that rests on the upper surface of the mounting plate 31. The limit block 332 slides on the mounting plate 31 while the guide rod 331 moves in the guide groove 311, providing longitudinal support for the conveying claw hook 33, so that the pin shaft in the conveying claw hook 33 remains vertical when moving with the conveying claw hook 33, thereby better cooperating with the drilling mechanism 4 and the unloading mechanism 5.

[0031] Preferably, a positioning hole 421 is provided on the end face of the positioning seat 42, and a first penetration hole 422 for the boring tool 44 to pass through is provided on the side wall of the positioning hole 421. When the positioning seat 42 moves toward the pin shaft along with the lifting plate 41, the lower end of the pin shaft is inserted into the positioning hole 421. The positioning hole 421 provides support for the pin shaft when the boring tool 44 passes through the first penetration hole 422 to drill the pin shaft, so that the pin shaft remains stable, thereby ensuring the drilling effect.

[0032] Preferably, the lifting plate 41 is provided with a dust cover 47 covering the positioning seat 42, and a second penetration hole 471 for the boring tool 44 to pass through is provided on the side plate of the dust cover 47, and the positioning seat 42 is fixedly connected to the top plate of the dust cover 47 so that a recovery gap is formed between the lower end of the positioning seat 42 and the mounting plate 31, and a recovery port 411 connected to the dust cover 47 is provided on the lifting plate 41. When the boring tool 44 passes through the second penetration hole 471 and the first penetration hole 422 in sequence to drill the pin shaft retained in the positioning hole 421, the generated debris and dust falls into the dust cover 47 without generating splashing of the debris and dust, and the debris and dust falling into the dust cover 47 falls out of the dust cover 47 through the recovery port 411, which is convenient for the recovery of the debris, and in order to achieve a better recovery effect, an exhaust device can also be connected to the recovery port 411.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
