Studies On Optimal Design And Application Of QMSK Automatic Grinding Machine

With "Made in China 2025" was put forward, China’s machinery manufacturing industry is developing towards the direction of intelligent, efficient and environmental protection. As the basic of machinery manufacturing, the foundry industry advocates the concept of "green casting". However casting grinding shop floor has poorer working conditions and lower level of automation in the machinery manufacturing plants. Meanwhile the flue gas, dusts, noises pollution is mostly focused on the place, which has become a major challenge to the foundry industry, due to its obstruction of the realization of "Made in China 2025" goals. Currently, the realization of casting grinding plant’s machinery and automation has become an inevitable trend of the foundry industry development.This paper is mainly engaged in the work of the development and application of QMSK automatic grinding machine, studies on its mechanical structure design, finite element analysis, structural optimization and the realization of automatic grinding. 3D modeling software SolidWorks was used to design and model the automatic grinding machine. Meanwhile, ANSYS Workbench was used to analyze the main mechanical structure of X axis machine tool stent about its finite element analysis and structural optimization. Under the precondition of ensuring mechanical properties to economize its manufacturing costs greatly.In this paper, the structure and function of QMSK automatic grinding machine were introduced first. According to the design scheme of the equipment and the function of each part, the 3D modeling software Solid Works was used to model and select the structure of the equipment and also, the function of each structure was introduced.Again, the X axis machine tool stent which is the main load-breading structure of QMSK automatic grinding machine was selected to study by ANSYS Workbench. And the finite element static analysis and modal analysis were also used to study X axis machine tool stent. The rigidity and the first six-order natural frequency of the X axis machine tool stent was checked and analyzed, respectively. Moreover, the various modal vibration patterns were described, and the rationality of the structural design was verified in theoretically, so to avoid the resonance.Then Multi-Objective Optimization of ANSYS Workbench was used to optimize the structure of X axis machine tool stent. Also the thickness of each plate on X axis machine tool stent was taken as the design parameters, and the total mass, the deformation and the equivalent stress was taken as target parameters. Then via the given objective function to optimize it. Finally we selected the optimal parameters by combining the response surface analysis with sensitivity analysis to re-model X axis machine tool stent. Static analysis and modal analysis were taken for the new model, and then it was compared with the finite element analysis results of former X axis machine tool stent. The results show that the total mass of the X axis machine tool stent is reduced 11%, up to 454 kg.At the end of this paper, the two-dimensional code technology and the machine vision were combined of automatic identification system, which was applied to casting recognition and detection to realize automatic grinding of grinder and ensured the reliability of the results. Collected and analyzed the operation in field efficiency of work and quality of product and summed up the optimal operation state of grinder at different situation.
