The locking structure 109 includes a hydraulic cylinder 118, a push block 119 and an arc-shaped locking plate 120. The above-mentioned solution solves the problem of the existing piston pin processing device. Since the front and rear ends generally need to be processed during the processing of the piston pin, after processing one end, it needs to be disassembled and replaced with the other end and re-clamped, which greatly affects the processing efficiency.

[0025] According to this specific embodiment, the machine tool 101 is used to support the installation of the processing assembly.

[0026] Among them, the drilling structure 102 is arranged on one side of the machine tool 101; the load-bearing seat 103 is fixedly connected to the machine tool 101 and is located on one side of the machine tool 101; the rotating motor 104 is fixedly connected to the load-bearing seat 103 and is located on one side of the load-bearing seat 103; the coupling 105 is fixedly connected to the output end of the rotating motor 104 and is located on one side of the rotating motor 104; the U-turn seat 106 is fixedly connected to the coupling 105 and is located on one side of the coupling 105; the fixed frame 107 is fixedly connected to the U-turn seat 106 and is located on one side of the U-turn seat 106; the arc-shaped placement seat 108 is fixedly connected to the fixed frame 107 and is located on one side of the fixed frame 107; the two locking structures 109 are respectively arranged on both sides of the fixed frame 107, and the workpiece raw material is placed when the piston pin is processed. The workpiece material is placed on the arc-shaped placement seat 108 in the fixing frame 107, and then the two locking structures 109 are controlled to cooperate with the arc-shaped placement seat 108 to fix the workpiece material. After the workpiece material is fixed, the drilling structure 102 is controlled to process and drill it. After one end of the workpiece material is processed, the drilling structure 102 is controlled to move away from the workpiece material. Then, the rotating motor 104 on the load-bearing seat 103 is controlled to drive the U-turn seat 106 to rotate through the coupling 105, and the unprocessed end is rotated to the side facing the drilling structure 102. Then, the drilling structure 102 is controlled to process and drill the other end. This solves the problem of the existing piston pin processing device. Since the front and rear ends generally need to be processed during the processing of the piston pin, it is necessary to disassemble and replace the other end after processing one end, which greatly affects the processing efficiency.

The workpiece material is continuously pushed forward for drilling processing. After one end of the workpiece material is processed, the propulsion cylinder 112 is controlled to drive the drill bit 114 to retreat so that the drill bit 114 is away from the workpiece material. Then, the rotating motor 104 on the load-bearing seat 103 is controlled to drive the turning seat 106 to rotate through the coupling 105, and the unprocessed end is rotated to the side facing the drill bit 114. Then, the propulsion cylinder 112 is controlled to drive the drill bit 114 to approach the workpiece material to drill the other end thereof, thereby solving the problem of the existing piston pin processing device.
