Description

Technical Field

[0001] The utility model belongs to the technical field of electric welding machines, in particular to a seamless welding fixture for welding machines. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "A welding fixture for electric welding machines", and its announcement number is "CN213945425U". This patent mainly includes a base, and the upper side walls at both ends of the base are fixedly connected to brackets. The outer side wall of the bracket located on the right side is fixedly connected to a motor, and the output shaft of the motor passes through the bracket and is fixedly connected to a rotating shaft. The outer side wall of the rotating shaft is slidingly sleeved with two sliders, and an adjustment mechanism is provided between the two sliders and the rotating shaft. The outer side walls of the two sliders are fixedly connected to a clamping plate 1, and the upper side wall of the clamping plate 1 is fixedly connected to a support rod 1. The utility model realizes the clamping of the weldment and the mother part by the second clamping plate through the return movement of the driving end of the telescopic rod, thereby improving the stability of the welding, and drives the rotating shaft to rotate by the motor to adjust the angle between the weldment and the mother part, which facilitates the welding between the weldment and the mother part, and the distance between the two clamping plates 1 is adjusted by the rotation of the turntable, thereby achieving the effect of seamless welding between the weldment and the mother part.

[0003] However, the above device can only fix the two welds at a certain angle and cannot adjust the connection angle of the two welds according to actual conditions, which will lead to unnecessary errors in the welding process. Specifically, when the welding angle does not fully match the design requirements, it may affect the strength and appearance of the weld, and thus affect the performance of the entire structure. Utility Model Content

[0004] The purpose of the utility model is to provide a seamless welding fixture for a welding machine. By providing a fixture mechanism, the fixed ring, the circular shaft and the connecting rod cooperate with each other, so that the connecting block two can slide on the outer wall of the fixed ring, so that it can adapt to the welding of different angles between the connecting pipe one and the connecting pipe two, greatly improving the applicability of the overall device. This design not only enhances the flexibility of operation, but also simplifies the welding process, so that workers can adjust the welding angle more efficiently when welding the connecting pipes, thereby ensuring the welding quality, and solving the problem that the connection angle of the two welds cannot be adjusted according to actual conditions, which will cause unnecessary errors in the welding process.
