Industrial robot-based assembly method and device of piston, piston pin and connecting rod

Abstract

The invention relates to an industrial robot-based assembly method and device of a piston, a piston pin and a connecting rod. The method of the invention comprises the following steps: a vision camera is used to identify the positions and directions of the piston, piston pin and connecting rod, the grabing positions are calculated by a computer, a mechanical paw grabs the piston, the piston pin and the connecting rod to place on an intelligent assembly table; the connecting rod is inserted in the piston under the control of the intelligent assembly table; an industrial robot places the piston pin in a piston assembly hole; the vision camera in the device identifies and positions the piston, piston pin and connecting rod on a work platform; the data terminal of the industrial robot is connected with the data terminal of the computer; the vision camera is connected with the computer; the industrial robot controls the mechanical paw to grab the piston, piston pin and connecting rod and place on the intelligent assembly table; the serial signal line of the intelligent assembly table is connected with the computer, the control circuit board of the intelligent assembly table controls a connecting rod jig to insert the connecting rod in the piston; and the industrial robot assembles the piston pin in the piston assembly hole according to the sensorless assembly method.

Description

technical field [0001] The invention relates to an engine piston, piston pin and connecting rod assembly method and device based on an industrial robot. Background technique [0002] The engine is the "heart" of the car, and its manufacturing technology is the concentrated expression of the whole vehicle manufacturing technology. Whether the engine can be guaranteed to have good performance and achieve reliable operation depends to a large extent on the final process of the engine manufacturing process - assembly. The engine assembly line can complete the assembly of products through reasonable process regulations and correct operation methods on the premise of saving costs to meet the needs of production. The flexible and automated production process can improve product quality and increase production efficiency on the one hand, and reduce labor intensity on the other hand. [0003] Due to its advantages of high degree of automation, high flexibility, small installation s...
