Problems solved by technology
[0002] During the production process of the outboard motor crank, it is necessary to perform processing procedures such as drilling eccentric holes, boring eccentric holes, milling key slots, and turning eccentric planes. The existing processing methods are relatively primitive and the processes are disordered, resulting in low efficiency and poor precision, which cannot meet Yield and quality requirements for batch processing

Description
technical field [0001] The invention relates to a processing technology of an outboard engine crank. Background technique [0002] During the production process of the outboard motor crank, it is necessary to perform processing procedures such as drilling eccentric holes, boring eccentric holes, milling key slots, and turning eccentric planes. The existing processing methods are relatively primitive and the processes are disordered, resulting in low efficiency and poor precision, which cannot meet Yield and quality requirements for batch processing. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a processing technology for the crank of an outboard motor. [0004] The technical solution of the present invention is realized like this: a kind of processing technology of outboard engine crank comprises the following steps: [0005] ① Install the crank workpiece on the eccentric hole dril...
