Study On Virtual Design Of Hydraulic Manifold Block CAD

With the develpoment of modern equipment manufacturing engineering, Hydraulic manifold block (HMB) schemes are used more and more widely in hydraulics and pneumatic circuit system,HMBS offers many advantage including reduced connectors, size and complexity. It provides a cleaner, leak- free, less vibrant and more reliable solution to difficult machine control system problems. But there are still many shortages in the way of HMB design, after studying and absorbing the research achievement in our country and abroad, Proposing the method which using the virtual design technology to solve the deficiency.The designer at the virtual design environment uses the virtual design technology to be directly capturing "virtual hydraulic valve" on the layout in the "HMB", Then the designer may be enter directly "the hypothesized holes network" center to examine holes each part of connecting with the interference situation,Thus designer may accurately determining the suitable shifting adjustment direction and adjustment quantity, By this means, this software reduces the design work load, the difficult of the spatial imagination, the design and the corrector time, finally assists the designer with ease to complete the design of Hydraulic manifold block.The software includes seven parts: the module of database design, the module of principium diagram digitization, the module of manifold blocks orientation design, the module of auromatic making holes for hydraulic manifold block, the module of corrector for hydraulic manifold block design, the module of 3D model design of hydraulic manifold block and the module of virtual design.This system Adopts the object-oriented technique, in Integrated Development Environment VB, developments the second SolidWorks by ActiveX Automation, achievements the integrated block three dimensionalparameter design, and explains the virtual design of the hydraulic manifold block. By using it, a special HMB CAD software is successfully developed and it includes many functions such as design, calculation, 3D solid molding.
