With the rapid economic growth, improving the quality of people's lives and improve the living environment, vertical doors modern life has become an indispensable and office furniture and other environmental products, vertical door's design is increasingly showing a personalized, art and scale of features. However, our current legislature door hole slot axis machining is mainly used woodworking drilling machines, multi-axis drilling and loose-leaf woodworking drilling machines, machining processes such processing methods exist scattered, low precision and low degree of automation of many problems, both the processing precision, the machine structure, and production efficiency can not meet the requirements of modern processing. Therefore, it is an urgent need to design a new type of vertical door hole slot dedicated CNC machine tools, to meet the market demand, but also for the development of woodworking machinery provides a new idea to improve our level of CNC woodworking machines. In this paper, a typical vertical door opening slot for the processing of objects, holes through the door opposite the groove machining process analysis, design of the vertical door hole slot dedicated CNC machining equipment. Machine using X, Y, Z axis linkage gantry structure, mainly by the feeding mechanism, pusher, locating and clamping mechanism, the beam axis motion mechanism, gantry vertical drive mechanism, cutting agencies and electric control system components . In addition, the design of a pneumatic control mechanism dedicated positioning clamp, clamping the workpiece in a case of the machine axis linkage, to complete the processing of all processes, reducing the cumulative result of several clamping errors. Meanwhile, the use of ADAMS software pair of clamping mechanism pinion meshing simulation analysis, in order to verify that the design is reasonable. This article also beamed with ANSYS software movement mechanism of spindle gantry beams with finite element analysis, first of all, for gantry beam displacement and stress of static structural analysis, displacement and stress cloud; Second, for gantry beam at different frequency of vibration modal analysis, the natural frequencies of the gantry beam and mode shapes; Finally, for gantry beam outside the known frequency vibrations generated under load displacement response of the harmonic response analysis, the gantry beam points displacement response curves to provide a basis for structural optimization. In addition, Pro / NC module simulate CNC vertical door hole slot machining process to achieve a vertical hole slot door automatic programming process. Finally, in Pro / E environment for the entire CNC machine tools and assembly modeling, motion simulation and analysis of the model, the design can be found by analyzing the problems ahead for improvement and perfection, shorten product development cycles, reduce design costs.
