One series of cone welding workpiece is a key part of certain critical equipment;we detected the weld quality and geometric error to ensure the high quality. This paper we research the straight weld, the girth weld ultrasonic testing equipment and geometric errors laser automatic testing equipment. Since the testing equipments have a certain degree of correlation, this article also draws on product family design thought, the modular and parametric technique to design the different testing equipments. The kind of design greatly improves the quality, reduces the manufacturing costs, shortens the research and development cycle, receives very nice results.

A simplified model of self-balance screen was constructed by using SolidWorks, and then imported into the Simulation to analysis its structure and modal. The stress distribution, deformation and structural natural frequency, mode shapes under static loads of the self-balance vibrating screen were calculated to provide theoretical basis for the following analysis of the dynamic characteristics and structure optimization design of vibrating screen.

With the continuous development of CNC technology, its application is more and more extensive. In recent years, the application of CNC technology in the area of stage also made great achievements. This paper detailed a scientific and reasonable scheme of acrobatic stage machinery and its control part, using CNC technology in acrobatic stage, through the corresponding algorithm and software realizing the operation and control of any trajectory in 3D space, taking advantage of intelligent editing function of screen running track, and compared with the traditional acrobatic stage , it gets more flexible, stronger strain capacity.

Further development of SolidWorks with VB is carried out in this paper. Program and dimension driving methods are utilized for parametric design to realize the automatic generation of three dimension component and engineering drawing in SolidWorks. Intelligent generation of drawing is achieved by adjusting the view scale of engineering drawing, generating view size and cutaway view in order to improve the design efficiency and quality.
