Description

technical field [0001] The technology of the present invention relates to an automatic drilling and milling processing mechanical equipment for chain connecting pin shafts in the chain industry in the field of hardware machining, and is suitable for processing small holes and milling platforms for small pin shaft parts. [0002] Background technique [0003] At present, all large and medium-sized chain enterprises and related chain accessories processing enterprises in China use traditional drilling and milling equipment in the processing of the small holes of the chain connecting pins, and install some simple fixtures, which are manually processed by workers. . The production process is backward, the work efficiency is low (the average speed of mass production is about 15 seconds / piece), and the product quality is uneven (the deviation of the drilling size is large, exceeding 0.5mm). And each production enterprise needs a large number of workers to complete the processing...
