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. Background technique [0002] 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 work of t...

Problems solved by technology

[0003] In order to solve the technical bottleneck of the current chain industry in this production link and to solve this backward production method, this technology has solved this problem very well and realized the fully automatic production process of parts processing, which would have required a large number of manual labor. operation, and the parts that need to be completed in multiple processes are completed at one time, which greatly improves the production efficiency and product quality. Installed on the rack table, the automatic drilling and milling machine includes a vibrating plate, a feeding guide rail, a cylinder, a clamping fixture, a milling platform mechanism, a center hole drilling mechanism, a small hole drilling mechanism, a chamfering mechanism, and an octagonal eight-station Turntable, precision cam divider, high-speed electric spindle mounting seat, high-speed electric spindle front and rear adjustment handwheel, material distribution mechanism, motor and automatic drilling and milling machine main body support, the main body support of the automatic drilling and milling machine is on the table of the rack, and the There is an octagonal eight-station turntable on the front side of the main body support of the automatic drilling and milling machine. There is a precision cam divider behind the octagonal eight-station turntable. There is a motor on the rear side of the main body support of the automatic drilling and milling machine. Connected with precision cam splitter;
