[0002] In railway signaling projects, the quality of cable connections directly impacts signal transmission efficiency and railway operation safety. During railway signaling construction and maintenance, particularly for connecting and welding signal cables, a wire bonding device is required. Existing wire bonding devices typically use a clamp to secure the cable ends, then weld the secured cables using methods such as gas pressure welding, argon arc welding, and thermite welding. Clamps typically use snap-fit methods to secure the cable ends.

[0003] Existing application number CN202020008930.2 The utility model discloses a cable welding clamp, including a fixed seat, a receiving part, a rotating assembly and a pressure block, the receiving part and the rotating assembly are fixed on the fixed seat, the receiving part has a card slot for accommodating the cable, the width of the card slot gradually increases from the inside to the outside, the pressure block cooperates with the card slot to position the cable; the rotating assembly is movably connected to the pressure block, and the rotating assembly is used to drive the pressure block to move closer to or away from the card slot. The utility model drives the pressure block to cooperate with the card slot through the rotating assembly, which can quickly align and clamp the cable, which is beneficial to improving the consistency and reliability of welding; and the width of the card slot gradually increases from the inside to the outside, which is suitable for positioning cables of different diameters; the overall structure is simple, and it is convenient to carry and operate.

After the cable is fixed, there may be errors in the distance. The cable position needs to be frequently disassembled and adjusted to ensure that the distance between the two ends of the cable remains within the design range. The operation is relatively cumbersome. Moreover, after the visible side of the cable is welded, in order to weld the other side, the cable needs to be removed and turned over before being fixed and welded, which is cumbersome.
