Description

Technical Field

[0001] This utility model belongs to the field of robot ground rail technology, and in particular relates to anti-collision welding robot ground rail. Background Technology

[0002] Welding robots are often mounted on a ground rail during use, so that the ground rail can be used to move the welding robot and adjust its working position to meet its welding requirements.

[0003] When using robots to weld workpieces, some workpieces have multiple welding points. To improve work efficiency, multiple welding robots are installed on the same ground rail to perform welding operations at the corresponding positions simultaneously, ensuring the normal progress of the work. The existing ground rail has a one-piece carrier with a fixed bearing surface size. Since the bearing surface of the carrier is limited, when two or more welding robots are installed on the ground rail, the close proximity of the welding robots makes them prone to collisions during movement and turning, which can damage the welding robots and affect the welding progress.

[0004] To address the above issues, we propose a collision-resistant welding robot ground track. Utility Model Content

[0007] The detection assembly includes a first T-shaped block, a fixed rod, a detection plate, and a laser rangefinder. A first T-shaped groove is formed at the bottom of the inner cavity of the movable frame. The first T-shaped block is movably disposed within the first T-shaped groove, and the upper end of the first T-shaped block is fixedly connected to the bottom of the L-shaped support plate. The fixed rod is fixed to one end of the first T-shaped block. The detection plate is fixedly connected to the end of the fixed rod away from the first T-shaped block. The laser rangefinder is installed on one side of the detection plate, and the laser rangefinder cooperates with the adjacent detection plate.

The movable fit of the movable plate 4 and the lead screw 3 facilitates the adjustment of the mutual approach of the two adjacent movable plates 4. The hinge action at the two ends of the connecting arm 6 pushes the push plate 5 away from the lead screw 3. Under the movable fit of the L-shaped plate 7 and the avoiding groove 8, the L-shaped plate 7 is further pushed to the outside of the moving frame 2.
