[0046] The stamping device 8 can be implemented by using a punch head in conjunction with a steel stamping head. This does not belong to the innovative point of the present invention and will not be further specifically described. Technicians can refer to the existing technology to implement it.

[0047] Working principle: The feed push plate is driven by the feed cylinder to move, and the feed push plate pushes the workpiece to be processed that falls from the bottom layer of the feed placement through hole on the feed trough to the product positioning block of the hole expansion station, and the stroke and position of the workpiece to be processed are positioned by the lower limit column and the upper limit column, and then the positioning cylinder drives the positioning pressure plate downward, so that the positioning pin on the positioning pressure plate contacts the positioning hole on the workpiece to be processed to achieve the positioning of the workpiece to be processed; then the feed cylinder drives the feed push plate back to the initial position, and the workpiece to be processed at the bottom layer of the feed placement through hole falls freely to the feed trough to wait for the next feeding;

[0048] After the positioning platen moves downward to position the workpiece to be processed, the drilling machine drives the drill bit to work, and the reaming drill bit avoids the through hole and contacts the hole to be processed on the workpiece to be processed to carry out reaming. After the reaming is completed, the Y-axial movement of the transport slider is used to approach the product positioning block, and then the workpiece to be processed that has been reamed is clamped by the transport gripper, and then the Y-axial movement of the transport slider is used again to drive the transport gripper away from the product positioning block, and finally the workpiece to be processed on the transport gripper is sent to the reaming station through the X-axial movement of the transport slider, and the workpiece to be processed that has been reamed is sent to the product positioning block on the reaming station through the transport gripper, and then positioned by the positioning pin on the positioning plate on the reaming station, and then the reaming is completed by the reaming drill bit on the reaming station. After the reaming is completed, the above-mentioned working mode of the transport slider usually sends the reamed workpiece to the double-sided chamfering station to complete the single-sided chamfering through the chamfering drill bit, and then the workpiece with one side chamfered is flipped over by the flipping device and sent back to the product positioning block of the double-sided chamfering station, and the downward positioning of the positioning plate on the double-sided chamfering station and the chamfering of the chamfering drill bit are repeated to complete the chamfering of the other side.

[0049] After chamfering is completed, the product positioning block of the double-sided chamfering station is flipped again, and then the chamfered workpiece is sent to the fine twisting station through the handling gripper on the handling slide, and the fine twisting is completed by the fine twisting drill. After the fine twisting is completed, the handling gripper on the handling slide sends the fine twisted workpiece to the stamping station for stamping until the hole processing is completed, and then the material is discharged.

[0050] Through the stepper motor or servo motor in conjunction with the X-axis slide rail, Y-axis slide rail, flip drive device, front positioning protrusion, and rear positioning protrusion, it is ensured that the position of the workpiece to be processed can be controlled and is in the set position after each transportation and flipping.
