Description

Technical Field

[0001] The invention relates to a combined numerical control machining machine for a pin lock cylinder, belonging to the field of machining equipment. Background Art

[0002] Pin lock cylinders are mostly made of brass or aluminum. The pin holes, milled spring grooves, transmission blocks, and side grooves for reducing friction all need to be machined. There are many processes involved, and the positions that need to be processed are all over the surface of the lock cylinder. Currently, there is no automated equipment on the market that can complete all the processes at one time. Since the processing position of each process is different, the lock cylinder workpiece needs to be rotated in advance before being sent to each process to cooperate with the tool processing. The cylindrical shape of the lock cylinder workpiece easily leads to self-rotation displacement during transportation, resulting in the inability to accurately complete the transmission. Therefore, it is difficult to achieve automatic assembly line processing. Therefore, manufacturers on the market are still in the stage of processing by separate machines and processes, which increases labor costs and low production efficiency. Summary of the invention
