Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] An embodiment of the present utility model discloses a welding device for a steel core of a printing roller shaft. Refer to Figures 1-3 , a welding device for a steel core of a printing roller shaft, including a base 3, a plurality of first electric push rods 1 and a processing frame 2 are arranged on the upper part of the base 3, and the two first electric push rods 1 are symmetrically distributed on the left and right sides of the upper part of the base 3. One end of the first electric push rod 1 is provided with a slider 4, and the upper end of the slider 4 is provided with a first clamping mechanism 5 for clamping the steel core and the connecting head. Second clamping mechanisms 6 for assisting in clamping the steel core and the connecting head are arranged on the left and right sides of the processing frame 2, and a welding mechanism 7 for welding the steel core and the connecting head is arranged at the upper end of the processing frame 2;

[0030] Refer to Figure 1 , the first clamping mechanism 5 includes a first bearing seat 501 and a mechanical chuck 502. The first bearing seat 501 is arranged at the upper end of the slider 4 and can move left and right through the slider 4. The mechanical chuck 502 is arranged on one side of the first bearing seat 501 and is used for clamping the steel core and the connecting head.

[0031] By adopting the above technical solution, when welding the steel core and the connecting head, the end of the steel core can be clamped and fixed by the mechanical chuck 502 on the left side, and the end of the connecting head can be clamped and fixed by the mechanical chuck 502 on the right side.

[0032] Refer to Figure 2, the second clamping mechanism 6 includes a second bearing block 601 and a hollow mechanical chuck 602. The second bearing block 601 is arranged on one side of the processing frame 2, and the hollow mechanical chuck 602 is arranged on one side of the second bearing block 601, which is used to assist in clamping the steel core and the connector. The hollow mechanical chuck 602 is a power chuck with the model K51.

[0033] By adopting the above technical solution, the other positions of the steel core can be clamped and fixed by the hollow mechanical chuck 602 on the left side, and the other positions of the connector can be clamped and fixed by the hollow mechanical chuck 602 on the right side, which greatly ensures the stability when the steel core and the connector are welded.

[0034] Refer to Figure 2 , the welding mechanism 7 includes a second electric push rod 701 and a welding head 702. The second electric push rod 701 is arranged at the upper end of the processing frame 2, and the welding head 702 is arranged at the bottom end of the second electric push rod 701, which is used to weld the steel core and the connector.

[0035] By adopting the above technical solution, after the steel core and the connector are concentrically docked, the second electric push rod 701 works to drive the welding head 702 to move downwards to weld the steel core and the connector.

[0036] Refer to Figure 1 , a motor 8 is arranged on one side of one of the first bearing blocks 501, and the output shaft of the motor 8 is connected to one side of the corresponding mechanical chuck 502.

[0037] By adopting the above technical solution, when the steel core and the connector are welded, the motor 8 works to drive the mechanical chuck 502 on the left side to rotate, so that the steel core can rotate, and then the steel core and the connector can be welded in all directions.

[0038] Refer to Figure 3 , sliding grooves 9 are respectively arranged on the upper left and right sides of the base 3, and the bottom end of the slider 4 penetrates into the sliding groove 9 and is slidably connected with the sliding groove 9.

[0040] Working principle: When this utility model is in use, the electrical components appearing in this application are externally connected to a power source and a control switch during use. First, insert the steel core onto the mechanical chuck 502 on the left side, and then clamp and fix the end of the steel core through the mechanical chuck 502 on the left side. Then, the first electric push rod 1 on the left side works to drive the right end of the steel core to pass through the hollow mechanical chuck 602 on the left side and enter the interior of the processing frame 2. Then, the hollow mechanical chuck 602 can clamp and fix other positions of the steel core, making the steel core more stable during welding. Similarly, the mechanical chuck 502 and the hollow mechanical chuck 602 on the right side can be used to clamp and fix the connector. Then, the first electric push rod 1 on the right side works to drive the left end of the connector to be concentrically docked with the right end of the steel core. Finally, the second electric push rod 701 works to drive the welding head 702 to move downward to weld the steel core and the connector. And during welding, the motor 8 works to drive the mechanical chuck 502 on the left side to rotate, so that the steel core can rotate, and then the steel core and the connector can be welded in all directions, ensuring the welding effect between the steel core and the connector. There is no need for the staff to preliminarily weld the steel core and the connector first, which greatly improves the welding efficiency between the steel core and the connector.

[0041] When this utility model is in use, there is no need for the staff to preliminarily weld the steel core and the connector first, which greatly improves the welding efficiency between the steel core and the connector, and at the same time ensures the welding effect between the steel core and the connector.
