The Characteristics And Design For On-line Detection Equipment Of Auto Staping Parts

Traditional automobile stamping parts detection means are not reliable, lower Detection efficiency,No Quality Tracking and poor digital integration and it is Difficult to meet the modern factory-volume, high-speed and efficient detection in the practical requirements.Basing on the fully understanding of the working principle and the Mechanical structure of the traditional coordinate measuring machine, we introduced the on-line detection equipment for automobile punching parts(APODE),a new developing technologies and research findings of which was proposed. It laid the foundation to solve problem of the on-line detection for automotive stamping parts and digital integration, which has important engineering significance.The main contents of this paper are as follows:1)The working principle of the APODE.Based on the analysis of the detection principle and 3D point cloud alignment technology, equipmental structure, parameters, functions are described.2)The host structural design of the APODE.Starting from the use of the environment and the analysis of the CMM, it is easily to get the structural design of the equipment.Then the key equipment's components are designed and the digital model is built in the UG environment and Assemble and interference is conducted.3)APODE simulation analysis. In order to improve the vibration characteristics of the machine, Two guides are prompted:aerostatic guideway and LM rolling guideway.The comparison of the seismic characteristics is done. Then to reduce the dynamic error, the model is parametered and the dynamic simulation is done, which further optimize the dynamic characteristics of the equipment.4)APODE static and dynamic error analysis and correction. Firstly APODE static error sources are discussed; Second, Camera's dynamic position error, affected by the the driving force and the inertial force in the three directions, is analyzed. Initially a single-axis error model is established and the uniaxial error expression is given. In the end, the method to reduce APODE dynamic error is discussed.5)APODE CNC system design. Firstly, the main structure of the CNC system is proposed and the key devices are chosen. CNC Simulation, which is analysis of motor start-up performance under External Load and then to change the control strategy to optimize the motor start-up performance, is done based en the ADAMS...
