[0002] Excavators, also known as excavation machinery, are earth-moving machines that use buckets to dig materials above or below the surface of the machine and load them into transport vehicles or unload them to stockpiles. The materials excavated by excavators are mainly soil, coal, silt, and pre-loosened soil and rocks. From the development of construction machinery in recent years, the development of excavators has been relatively fast. Excavators have become one of the most important construction machinery in engineering construction.

[0003] In the welding process of the excavator track frame, the control wire seat needs to be welded to the track frame. When welding the wire seat, the staff needs to calculate and adjust the position of the wire seat before welding for subsequent installation and use. The traditional method is manual measurement and positioning, which is cumbersome and inefficient, further reducing production efficiency. After positioning, the operator is required to always support the wire seat to prevent the wire seat from shifting during welding, which is extremely inconvenient. Utility Model Content

Positioning modules 2 are arranged below both ends of the positioning rod 1. The positioning modules 2 cooperate with the bolt holes 12 on the track frame 11. Two symmetrical fixing seats 3 are arranged below the positioning rod 1 and the fixing seats 3 are arranged on the inner sides of the positioning modules 2 on both sides. A connecting seat 5 is arranged above the connecting rod 4. The connecting seat 5 is connected to the fixing seat 3 by bolts. An axle seat 6 is arranged below the connecting rod 4. A telescopic module 8 is arranged below the axle seat 6. The telescopic module 8 is connected with a positioning shaft 9. The positioning shaft 9 cooperates with the position of the wire seat 13.

[0024] The telescopic module 8 includes a shell 81 and a movable block 82. The shell 81 is a tubular body. The movable block 82 is matched with the inner cavity gap of the shell 81 and can slide in the inner cavity. A slide groove 84 is arranged inside the tubular body. One end of the slide groove 84 is in a closed state to prevent the movable block 82 from popping out. A slider 83 is arranged on the side of the movable block 82. The slider 83 is slidably connected with the slide groove 84. A spring seat 86 is connected to the upper end of the shell 81.
