Abstract
The invention discloses a method and a system for generating an equipment process detection curve, a storage medium and electronic equipment. The method comprises the following steps: acquiring various physical assembly data in a press-fitting assembly process; obtaining a preset data regression relational expression; according to at least one type of physical assembly data, first physical assembly data of the regression relational expression is obtained through calculation based on the regression relational expression, and second physical assembly data is obtained through calculation by adopting a linear proportional relation; fitting numerical values of the first physical assembly data and the second physical assembly data on a coordinate system to obtain a two-dimensional data curve in the coordinate system; and obtaining a detection curve of the press-fitting assembly process based on the two-dimensional data curve and a preset quality requirement. The technical problem that traditional automatic press-fitting equipment cannot carry out fine process detection due to the fact that process data cannot be output is solved, upgrading of the digital assembly process of the press-fitting equipment is achieved, and the transformation and upgrading cost is further reduced.
Description
technical field [0001] The invention relates to the technical field of engine detection, in particular to a method, device, storage medium and electronic equipment for generating a detection curve of an oil seal press-fitting process. Background technique [0002] In the process of engine production and assembly, interference fit installation of components is involved to meet the sealing requirements, such as the assembly of the front and rear oil seals of the engine crankshaft. The traditional oil seal assembly is to smash the oil seal into the installation hole by violent means, without considering the pressure performance of the press-fitting process during the press-in process. At this time, the state of the parts and the randomness of the installation will cause fluctuations in the assembly quality. With the continuous improvement of assembly quality requirements, automatic press-fitting equipment driven by motors / hydraulic pressure and equipped with pressure and displa...
