Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a turntable type continuous brazing device. Background Art

[0002] PMA plasma brazing machine completely replaces traditional brazing equipment. It is a new generation of brazing equipment that does not require flammable gas and adopts IGBT inverter control principle. During welding, the flame is very stable. The whole equipment is light and convenient, suitable for outdoor welding. The welding machine is simple to operate and can be operated by people who know a little about welding. No special training is required. This product does not require acetylene and other flammable and explosive gases, and the safety performance is greatly improved. Only electricity is needed. The advantages of using plasma brazing machines in some underdeveloped areas (no oxygen or acetylene, gasoline, etc.) are very obvious. During the welding process, gas flux can be directly used instead of the traditional manual addition of borax to improve the wettability and fluidity of brazing, so as to reduce the formation of pores and improve the tensile strength of the weld. There is no oxidation on the surface during welding, and it does not turn black. No pickling is required, which greatly improves the effective welding efficiency.

[0003] The patent document with the prior art publication number CN211072149U provides a turntable composite brazing machine, which has a simple structure, is easy to use, and has strong practicality. It is equipped with a drive motor and a drive wheel, which can realize automatic wire feeding and high welding efficiency. It is equipped with a rotating motor and a rotating welding disk, which can realize rotary welding and has good welding effect. However, there are some defects in the existing CN211072149U patent. Brazing is mainly used for welding pipe-type workpieces. The center of gravity of pipe-type workpieces is high. If they are directly placed on the rotating welding disk without being fixed, they are easy to fall over once they are rotated, which is not conducive to welding. In addition, the welding head is arranged above the rotating welding disk, and the horizontal position is fixed. It is impossible to weld pipe-type workpieces of different sizes, and the scope of application is small. Therefore, a turntable continuous brazing device is urgently needed. Utility Model Content

Power supplies and controllers are arranged on the left and right sides of the motor 3 in the device for driving the motor 3. The motor 3 drives the connecting rod 2 to rotate, thereby driving the placement table 4 to rotate. The lower surface of the placement table 4 does not contact the workbench 1, which is conducive to the stable rotation of the placement table 4. A first slide groove 5 is opened inside the placement table 4, and a double-headed reverse screw rod 6 is rotatably connected to the inside of the first slide groove 5. The left end of the double-headed reverse screw rod 6 is connected to a first knob 7. The outer side of the double-headed reverse screw rod 6 is threadedly connected with an active The movable plate 8 is provided with a clamping plate 9 welded on the top of the movable plate 8, the bottom end of the movable plate 8 is slidably fitted with the inner wall of the first slide groove 5, and the movable plate 8 forms a sliding structure with the placing table 4 through the first slide groove 5.

The movable plate 8 and the clamping plate 9 are both provided with two, and the clamping plate 9 is provided with a "V"-shaped structure, and the end of the clamping plate 9 away from the movable plate 8 is covered with a rubber pad. The pipe-shaped workpiece is clamped and fixed by the "V"-shaped clamping plate 9. Since the movable plate 8 can be translated, the clamping plate 9 can effectively clamp pipes of different sizes. The setting of the rubber pad prevents the clamping plate 9 from scratching the pipe-shaped workpiece. The bottom support columns 10 are fixed at the four corners of the lower surface of the workbench 1.
