Description

Technical Field

[0001] The invention relates to a guide pin and a processing method thereof, in particular to a spring positioning guide pin for key processing and a processing method thereof, belonging to the technical field of key processing. Background Art

[0002] Key is a commonly used unlocking tool in people's lives. The materials for making keys are mainly copper, zinc, aluminum, iron and other metals.

[0003] Key processing equipment, also known as key milling machine, is a small lathe used to copy keys. In existing key processing equipment, positioning guide pins are often required. The principle of key configuration is mainly profiling. Guide pins are used as the basis for profiling on the original key. Because the marbles of the key of the marble lock cylinder have different angles, the configuration of the punch key requires guide pins and tools with more angles, which makes it costly for the locksmith to prepare the guide pins and difficult to distinguish and preserve.

[0004] Chinese invention patent publication number CN 103722452 A discloses "a key processing device", which relates to the field of key-making mechanical equipment. A motor is arranged on a base, and a shaft is arranged at one end of the motor. A plurality of milling cutter grooves are arranged on the shaft. The milling cutter is clamped in the milling cutter groove. A fastener is arranged on one side of the milling cutter. A fixing seat is arranged at one end of the base. A thimble is arranged on the fixing seat. A key fixing seat is arranged at the front end of the thimble and the milling cutter. A mother key fixing groove and a plurality of child key fixing grooves are arranged on the key fixing seat. The bottom of the key fixing seat is sleeved on a slide rail, and the slide rail is connected to a driving device. A switch is arranged on the driving device. It has a simple structure and is easy to operate. It can copy several keys at the same time. A key fixing seat is arranged at the front end of the thimble and the milling cutter. If the guide pin is fixed, then once a keyhole cannot be processed, multiple keys will not be processed. Moreover, the guide pin needs to be frequently replaced for the keys that cannot be processed, so the processing efficiency will be greatly reduced.

[0005] Therefore, it is urgent to improve the spring positioning guide pin for key processing to solve the above-mentioned problems. Summary of the invention
