Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, the present invention provides a small mobile welding robot, including a wheeled mobile platform 2, a welding torch adjustment mechanism, and an arc sensor 4. The wheeled mobile platform adopts a differentially driven three-wheel structure, and two driving wheels are arranged at the rear of the robot. , constitutes the working plane with the front universal wheel to ensure that the robot can move reliably on the workpiece; the two driving wheels are independently driven by two stepping motor drive systems, and the trajectory planning and tracking of the robot are realized through different speed controls. Installed on the front of the robot An ultrasonic ranging sensor prevents the robot from colliding with the workpiece in front; at the same time, it is used to detect the distance between the robot and the wor...

Abstract

The invention relates to the technical field of welding robots, in particular to a small mobile welding robot. The small mobile welding robot comprises a wheeled mobile platform, a welding torch adjusting mechanism and an arc sensor, the wheeled mobile platform is of a three-wheeled differential driving structure, an adjustable magnetic adsorbability is mounted at the bottom, and a controller is integrated on the mobile platform. The welding torch adjusting mechanism is composed of a cross slider and a welding torch connecting device, the cross slider is driven by two motors respectively, and horizontal and vertical accurate tracking of welds is realized; the arc sensor adopts a conical pendulum form and is designed with a welding gun integrally, and convenience in use is achieved. The robot meets the requirements of bend weld tracking, and is good in welding quality, small in size, lightweight, convenient to use and the like, and the requirements on welding robots in narrow space are met.

Description

technical field [0001] The invention relates to the technical field of welding robots, in particular to a small mobile welding robot. Background technique [0002] With the improvement of people's requirements for welding quality and welding efficiency and the cost of manual welding, the demand and use of welding robots are becoming more and more extensive. In shipbuilding, in order to strengthen the strength of the hull, there are usually many lattice-shaped frame structures at the bottom of the cabin. Due to the narrow working space of the structure, the welding workers are physically uncomfortable when working. [0003] It can be stretched freely, and the working conditions are very harsh, so that the development of welding robots for this type of structure has good economic and social benefits. However, the existing industrial manipulator cannot weld large-sized workpieces because its arm length is generally 1.5-2.0 m, and the base cannot move in a large range; for the...
