Problems solved by technology

However, the drive motors of such welding robots with traditional open-chain series structure must be installed at the joints, resulting in problems such as heavy weight, poor rigidity, large inertia, and accumulated joint errors. The dynamic performance of the mechanism is poor, and it is difficult to meet high-speed Handling and palletizing requirements

Abstract

A four-degree-of-freedom double-push cylinder type welding robot, the first electric push rod drives the fifth sliding sleeve to move back and forth on the forearm, the second electric push rod drives the third sliding sleeve to move back and forth on the forearm, and the third The sliding sleeve and the fifth sliding sleeve control the movement of the actuator through the link mechanism composed of the third connecting rod to the fifteenth connecting rod. The invention realizes the series transmission of the crank slider mechanism, overcomes the shortcomings of the traditional four-bar transmission mechanism such as low overall rigidity and large space occupation, and has the characteristics of compact transmission structure and high reliability. Connect in series to realize the coaxial transmission of slider rotation and slider sliding.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a four-degree-of-freedom double-push cylinder welding robot. Background technique [0002] Welding robots are widely used in automatic handling operations such as loading and unloading of machine tools, automatic production lines of stamping machines, automatic assembly lines, handling and palletizing, and containers. The existing welding robots mainly have three structural types: Cartesian coordinate type, cylindrical coordinate type and joint type. Among them, the articulated welding robot has gradually become the main structural form of the welding robot because of its compact structure, flexible movement, small footprint, and large working space. However, the drive motors of such welding robots with traditional open-chain series structure must be installed at the joints, resulting in problems such as heavy weight, poor rigidity, large inertia, and accumulated joint errors. The dynamic...
