To solve the problems of difficult slag picking, danger, and low efficiency of manual slagging in the casting process, a double-cam connecting rod slagging structure is designed for the zinc ingot production line. First, a set of linkage mechanisms for slagging action is designed using geometric formulas, which are applied to the design of the overall contour of the cam through Excel and SolidWorks' Cosmos/Motion plug-ins, and then the kinematics simulation is carried out using Adams software. Finally, the simulation results show that the double cam connecting rod slag structure has stable work, reliable structure, no obvious vibration shock, and the mechanical structure meets the requirements in the process of simulating the removal of zinc slag.
Taiwan Photon Source is a new 3-GeV ring with characteristics of great brightness and small emittance, at present under construction at National Synchrotron Radiation Research Center (NSRRC) site in Taiwan and due to be commissioned in 2013. The positioning of the magnets is highly sensitive to alignment errors, and the entire building will be constructed half underground at depth 12 m relative to Taiwan Light Source (TLS) for stability reasons; for these reasons the survey and alignment work is confined and difficult. To position magnets precisely and quickly, a highly accurate auto-tuning girder system combined with a survey network was designed to accomplish the alignment tasks. The survey network includes a preliminary Global Positioning System (GPS) network and a laser-tracking network. The position data from the survey network define a basis for the system of motorized girders to auto-tune and improve the accuracy. The detailed survey and alignment design, simulation and preliminary data are described in this paper.
Taiwan Photon Source (TPS), a new 3 GeV synchrotron ring, is under construction at National Synchrotron Radiation Research Center (NSRRC). To discover problems of design, manufacture and installation, a mockup of 1/24 section (one cell) of TPS was installed at NSRRC. A modified, precise, six-axis, prototype girder system of this mockup composed of three girders was fabricated. We discuss both the installation of the girder system and its diagnostics, and present the results including measurement of the dimensions of the components of the girder system and the vibration tests.
