AI Technical Summary
In existing ground-rail welding robot workstations, the tail seat of the displacement machine is prone to inaccurate position pushing, which makes the displacement machine unable to accurately clamp.
The drive mechanism of the screw and thread sleeve is adopted. The thread sleeve is driven to move along the length of the ground rail by rotating the screw, adjusting the spacing between the tail seat and the head seat of the positioning machine, thereby achieving accurate position adjustment.
The position pushing accuracy of the tail seat of the displacement machine is improved to ensure that the displacement machine can be clamped accurately, solving the problem of inaccurate position under traditional motor or cylinder pushing methods.

[0032] The floor-mounted welding robot workstation is a combination of welding robots, floor rail systems, welding power supply systems, robot moving systems, workstation control systems, and welding tooling and other equipment. The design of this workstation aims to improve welding efficiency and quality. Through the floor rail system, the robot can move freely within the working area to perform multi-station welding tasks. The floor-mounted welding robot workstation is usually applied in fields such as steel structure processing and the welding of H-beam workpieces. By using two robots moving on the same floor rail for multi-station welding, automated welding is achieved, improving production efficiency and product quality. In addition, the floor-mounted welding robot workstation also has high flexibility and adaptability, and can adapt to the welding requirements of workpieces of different sizes and shapes. By adjusting the position of the robot and the configuration of the tooling, diverse welding operations can be realized.
[0033] In the prior art, when mechanically welding some longer steel plates, a positioner is usually used. The positioner is divided into a positioner headstock and a positioner tailstock. Usually, the positioner tailstock is movable, that is, for the convenience of placing the steel plate. However, usually, a second motor or a cylinder is used to push the positioner tailstock, which is likely to cause inaccurate position pushing and the positioner cannot accurately clamp.
[0034] Based on this, in order to improve the technical problem in the related art that the positioner tailstock is prone to inaccurate position pushing and the positioner cannot accurately clamp, the embodiments of the present application provide the following solutions.
[0035] Please refer to Figures 1 to 5 , the embodiments of the present application provide a floor-mounted welding robot workstation, including a first base 10 and a second base 20 arranged on one side of the first base 10.
