A manipulator telescopic device for a welding robot used in the manufacture of RV trailers

Abstract

The invention discloses a manipulator telescopic device for a welding robot used in manufacturing a caravan trailer, relates to the field of welding robots, and includes a connecting plate, a telescopic mechanism, a distance measuring mechanism and a lubricating mechanism. The telescopic mechanism includes an inner tube located at one end of the connecting plate. The outer wall of the inner tube is connected with a limiting plate. In the present invention, a lubricating mechanism is provided. During the moving process of the device, the motor drives a turntable to rotate, and one turntable drives the other turntable to turn through a belt. When the hole is rotated to the outside of the oil tank, its opening end is high, and the lubricating oil on the inner wall of the oil tank can be scooped in. When the rotating plug is rotated to the side away from the oil tank, the opening end of the oil hole is at a low position, and the lubricating oil is ready It slides out along the oil hole and flows into the oil passage, and the lubricating oil in the oil passage continuously contacts with the telescopic tube, so as to achieve a lubricating effect, reduce mechanical wear and improve the service life of the device.

Description

technical field [0001] The invention relates to the field of welding robots, in particular to a manipulator telescopic device for a welding robot used for manufacturing a caravan trailer. Background technique [0002] A welding robot is an industrial robot engaged in welding (including cutting and spraying). According to the definition of a standard welding robot in the International Organization for Standardization (ISO), an industrial robot is a multi-purpose, reprogrammable automatic control operation machine (Manipulator ), with three or more programmable axes, used in the field of industrial automation. [0003] However, the current manipulator telescopic device cannot monitor its elongation length in real time during operation, resulting in the inability to effectively avoid device error operation during the working process. At the same time, during the telescopic process of the existing device, the inner tube is in contact with the telescopic arm The surface of the d...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the elongation length cannot be monitored in real time during operation, resulting in the inability to effectively avoid the erroneous operation of the device during the working process, and the contact surface between the inner tube and the telescopic arm will always produce friction, and long-term use will cause mechanical wear of the device Seriously, the problem that affects the service life of the device is to provide a manipulator telescopic device for a welding robot used in the manufacture of RV trailers
