Abstract:Aiming at requirements of the automatic loading and unloading of bent axle of compressor in refrigerator during the grinding process, the mathematical model of loading and unloading motion system of robot was set up. Based on SolidWorks Motion, motion characteristics of robot during the loading and unloading process was simulated and researched. The simulation result showed that on the condition of 5s of time for operation of each bent axle and in limited workspace, the robot could fulfill all the requirements. The loading and unloading robot of bent axle is under the successful application in practical production, and creates a precedent in grinding process.
