After taking over the cylinder automatic grinding project of the state-owned engine co., LTD., Yuyang specially assigned the chief expert who had participated in the national major automation technology project to participate in the research and development, fully considering the technical difficulties in the above industry, and to overcome all kinds of difficulties, and finally overcome the technical problems in the industry.
The engineer in charge of the project said that the project team first improved the deviation of the casting clamps through tests and found effective compensation measures. In this automatic grinding project, the advantages and disadvantages of the measured points in each part are compared and calculated again. When selecting the measuring points, the variation points of the cylinder block, the cutting and grinding path of the cylinder block and the points, lines and surfaces that can affect the machining quality are taken into full consideration.
When clamping the cylinder block, cylinder was selected as the clamping point, and some stable points of the lower cylinder block were selected as the fixing point, which was determined after repeated tests. In this way, both the proportional algorithm and the differential method are easier to achieve the accuracy of detection.
Yuyang specialized more in the development of a system of procedures to control compensation measures. During the implementation, after the cylinder is measured by laser, the corresponding data is transmitted to the control system in real time, and the specially developed software and modules for this project are compared and calculated, so as to generate a compensation program and guide the robot to cut and polish the cylinder.
Secondly, the project team re-planned the trajectory of the robot. Yuyang has close cooperation with KUKA, Siemens and other companies. In the research and development and practice, the soft implementation of 3d simulation with executive software solves various possibilities of offline programming. The calculation software developed by Yuyang can repair and compensate the planning path of the robot, so that the simulation effect is close to the real machining track. Then the simulation software of the robot is used for calibration and re-planning, making the trajectory planning more real and more efficient.
Finally, the choice of polishing products is reasonable. People in the industry know that castings vary in size, quality and structure. For different types of castings, Yuyang has successfully developed intelligent grinding equipment and intelligent robot as early as 2015. It can be said that different types of castings can be handled with ease.
