Description

Technical Field

[0001] The utility model relates to the technical field of double-station medium-frequency inverter spot welding machines, and more specifically, to a double-station medium-frequency inverter spot welding machine. Background Art

[0002] In the existing technology, the double-station medium-frequency inverter spot welder is a welding device widely used in the metal processing industry. It realizes efficient spot welding operations by providing a stable welding current. However, this equipment needs to be connected to a cable during use in order to obtain the required electrical energy from the power supply. However, since the spot welder may need to move during operation, this brings up the problem of cable fixing. If the cable cannot be effectively fixed, it may be damaged during movement, such as being stretched, folded or entangled, which will not only shorten the service life of the cable, but also cause the current to be unstable during welding, affecting the welding quality.

[0003] In addition, cable damage may also lead to safety accidents, such as electric shock or fire. Therefore, ensuring the safe fixation of cables during the movement of spot welding machines is the key to improving the use of equipment and ensuring the safety of operators. Existing spot welding machines may have deficiencies in cable fixation, such as the lack of effective cable fixing devices or the fixing method is not stable enough, which makes the cables vulnerable to damage during movement.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a double-station medium-frequency inverter spot welding machine, which has the following beneficial effects:

[0017] 1. The design of the fixing mechanism ensures the stable fixation of the cable during the movement of the double-station medium-frequency inverter spot welding machine. The effective fixation of the cable is achieved through the cooperation of the fixing sleeve, the synchronous sleeve and the threaded tube, as well as the application of the round head and the expansion spring. This mechanism makes the cable less susceptible to stretching or compression when the welding gun moves, thereby protecting the structural integrity of the cable, extending its service life, ensuring the stability of the current during welding, and improving the welding quality.

[0018] 2. The sliding mechanism provides flexible and firm support for the cable through the setting of the shrink sleeve and the slider. The cooperation of the spring and thrust bearing on the slider enables the slider to automatically adjust according to the diameter of the cable, ensuring that the round head can evenly contact the side wall of the cable and provide stable thrust. This design not only improves the adaptability of cable fixation, but also simplifies the operation process, making cable fixation more convenient and reducing operation time.

[0019] 3. The moving mechanism realizes the movement of the welding gun through the cooperation of the transverse sleeve, the follower frame and the hydraulic cylinder. The action of the hydraulic cylinder enables the welding gun to achieve fast and smooth transverse movement on the follower frame, thereby completing the welding process on the workpiece. The design of this moving mechanism improves the flexibility of the welding operation and enables the welding gun to adapt to the welding requirements of different workpieces.
