| With the rapid growth of car sales, the requirements of engine parts and components are also getting higher and higher. And the crankcase as one of the important parts of the engine parts, because of its die casting and other technological reasons, in its processing parts will produce flying edge or burr. These flying edges or burr is not conducive to the processing, assembly and use of the products, and even reduce the working performance and service life of the automobile engine. In the enterprise inside these flying edges or burr cleaning work is generally have workers to polish treatment, which is not only time-consuming and labor-intensive, low efficiency, and even endanger the health of workers. Regarding the characteristics of 4G18 crankcase burrs, industrial robots as the main design an automated polishing clean-up program, the traditional grinding processes and methods were optimized to improve the automation of production lines, reduce labor intensity. The main contents are as follows:First of all, the reasons for the burr and removal methods were analyzed, combined with the user needs to develop a set of 4G18 crankcase cleaning and polishing system software and hardware platform solutions. The hard software platform of the cleaning and polishing system is introduced. On this basis, the cleaning process optimization technology, intelligent control technology and simulation technology are analyzed.And then the design of the cleaning and polishing process, and for grinding process of logical relationship, a general control system is designed with the NC812 and acquisition conveying line and the robot’s working condition and other information, to achieve the monitoring and control.Finally, the robot trajectory of polishing system was studied by using ROBCAD software. Through the establishment of the robot, the floating spindle automatic transportation lines and other related models ROBCAD software, using off-line programming technology of robotic grinding path of three dimensional dynamic programming simulation, interference detection and unreachability detection of polishing path, the feasibility of the subject of verification. |
