Abstract

The invention discloses a method for controlling laser parameters of a finely machined curved gear based on a dynamic effect mechanism. The method comprises the following steps of coupling dynamic effect mechanisms of a QHJ model, a QD model, a QX model, a QA model and a QC model to form a QZ model; inputting laser parameters into the QZ model, and obtaining output gear surface machining quality parameters; judging whether the gear surface machining quality parameters meet preset standards or not; if not, adjusting the laser parameters, and executing the step S2; and if yes, outputting the laser parameters. According to the control method, whether the requirements are met or not is reversely judged through analogue simulation according to the simulation result, and the required laser parameters can be effectively found. Compared with the prior art, the laser parameters can be effectively controlled, and therefore the machining precision is improved.

Description

technical field [0001] The invention mainly relates to the technical field of gear micro-correction processing, in particular to a laser parameter control method for micro-machining curved surface gears based on a dynamic effect mechanism. Background technique [0002] Surface gears are the key to realize intersecting or staggered transmission in space. They mainly include spiral bevel gears and face gears. They have many advantages such as large coincidence, strong bearing capacity, and stable high-speed transmission. They are widely used in aerospace, large-scale equipment, transportation, etc. Transportation, construction machinery and other fields. Therefore, the precision manufacturing of curved gears is one of the technological highlands and cutting-edge research fields that the world's manufacturing powers compete for a long time in the field of transmission. [0003] The tooth shape of the curved gear is complicated, the technical requirements are high, and the manu...
