[0002] A cable is a conductor made of one or more mutually insulated conductors covered with an insulating protective layer, and is laid underground or overhead. Cables generally consist of three components: a conductor, an insulating layer, and a protective layer. There are two common types of cables: power cables and control cables. Power cables are primarily used for the transmission and distribution of electrical energy; control cables are primarily used for measurement, protection, and control. Cables are characterized by internal current flow and external insulation. During cable production, the two cable joints must be welded.

A cable joint welding device for cable production according to any one of claims 1 to 9, characterized in that: Also included is a welding method for the cable production cable joint welding device: S1: Turn the first turning handle (11), the first turning handle (11) drives a first adjusting screw (10) to rotate, the first adjusting screw (10) drives another first adjusting screw (10) to rotate through the first synchronous wheel (12) and the first synchronous belt (13), the lower clamping plate (3) moves downward as the two first adjusting screws (10) rotate, and the cable connectors of the two sections of the cable are passed through the two clamping and fixing grooves (5) on both sides respectively, and then the first turning handle (11) is turned in the opposite direction, the first turning handle (11) drives the two first adjusting screws (10) to rotate in the opposite direction, the lower clamping plate (3) moves upward as the first adjusting screw (10) rotates, and the lower clamping plate (3) and the upper clamping plate (4) clamp and fix the cable; S2: rotating the turntable (21), the turntable (21) drives the first bidirectional screw (20) to rotate, the two T-shaped movable blocks (19) move in opposite directions with the rotation of the first bidirectional screw (20), the two T-shaped movable blocks (19) drive the two telescopic plates (15) and the fixed connecting plate (14) to move in opposite directions, and the two fixed connecting plates (14) drive the two welding fixed blocks (6) to separate; S3: Turn the second turning handle (25), the second turning handle (25) drives the second bidirectional screw (24) to rotate, the two adjusting sliders (23) approach each other as the second bidirectional screw (24) rotates, the two adjusting sliders (23) drive the two movable plates (2) approach each other, the two movable plates (2) drive the two lower clamping plates (3) and the two upper clamping plates (4) approach each other, the upper clamping plate (4) drives the telescopic plate (15) into the movable cavity (16), at this time the lower clamping plate (3) and the upper clamping plate (4) drive the cable connector into the two connecting clamping ports (7), and the two cable connectors come into contact with each other; S4: The turntable (21) is rotated in the opposite direction, and the turntable (21) drives the first bidirectional screw (20) to rotate in the opposite direction, and the two T-shaped movable blocks (19) drive the two fixed connecting plates (14) and the telescopic plate (15) to move closer to each other, and the two fixed connecting plates (14) drive the two welding fixing blocks (6) to move closer to each other, and at this time, the two cable connectors will be fixed inside the connecting clamping port (7), and the connection point will be at the intersection of the connecting clamping port (7) and the welding groove (8); S5: Add molten welding material into the combustion tank (9) and the welding tank (8), rotate the third handle (29), and the third handle (29) drives a second adjusting screw (28) to rotate. The second adjusting screw (28) drives another second adjusting screw (28) to rotate through the second synchronous wheel (30) and the second synchronous belt (31). The adjusting protection frame (26) moves downward as the two second adjusting screws (28) rotate. The adjusting protection frame (26) will cover the two welding fixing blocks (6). At this time, the molten welding material inside the combustion tank (9) and the welding tank (8) is ignited, so that the two cable connectors can be welded together.
