Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an auxiliary welding device. Background Art

[0002] Welding is a process that uses heat, high temperature, or high pressure to join metals or other thermoplastic materials. Typically, the edges of two materials are placed against each other on a surface. Workers then heat the edges to melt them, allowing the melted portion to cool and solidify, completing the connection.

[0003] For example, Chinese utility model patent publication CN218800073U discloses a "welding device" comprising a support frame equipped with a horizontal plate mechanism for facilitating automated welding in mechanical manufacturing. The horizontal plate mechanism comprises a pull plate and a C-shaped plate. Cylindrical slots are formed through the ends of both sides of the support frame. There are two pull plates, each with a connecting rod fixedly mounted on its side. Both connecting rods are rotatably mounted on the inner sidewalls of the cylindrical slots. There are two C-shaped plates, each with a telescopic rod fixedly mounted between the two C-shaped plates and the two connecting rods. This device incorporates a rubber pad, which is relatively soft and has a certain degree of friction. This ensures secure fixation when securing a mechanical workpiece. The curved end of the rubber pad is suitable for clamping mechanical workpieces of varying shapes.

[0004] However, since the above-mentioned device can only clamp shorter and smaller materials for welding, it has low adaptability and is difficult to clamp long tubular workpieces for welding. At the same time, the welding of cylindrical workpieces requires higher automation and precision control. The geometric shape of the cylinder makes the welding process more complicated, making it difficult to fix and dock the cylindrical workpieces, affecting the coaxiality requirements of the two workpieces. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides an auxiliary welding device, which solves the problem in the prior art that the transmission welding device is difficult to meet the welding requirements for cylindrical workpieces.

Each movable seat is adjusted by an adjustment device to change the distance between the corresponding fixed seat, and the two fixed seats and the two movable seats are used to place tubular parts; a C-shaped frame, one end of which is hinged to the operating table, and the other end is detachably connected to the operating table, and two groups of limit members are arranged on it, the two limit members correspond one-to-one to the two fixed seats, and are located on the upper side of the corresponding fixed seats, and the two limit members are used to press the tubular parts.

[0007] Compared with the prior art, the present invention has the following beneficial effects: by arranging a placement assembly for placing tubular parts and a C-shaped frame for limiting the position of the tubular parts on the operating table, the tubular parts are limited and fixed, so that the axes of two workpieces to be welded overlap to ensure their coaxiality. At the same time, with the setting of multiple sets of rollers, the welded workpieces can be rotated synchronously during the welding process, which is convenient for operation. At the same time, welding is performed along the butt joint without affecting the coaxiality due to rotation. The two sets of movable seats can be adjusted to change the distance between them and the corresponding fixed seats to adapt to welding workpieces of different lengths.

At the same time, with the setting of multiple sets of rollers 401, the welded workpieces can be rotated synchronously during the welding process, which is convenient for operation. At the same time, welding is performed along the butt joint without affecting the coaxiality due to rotation. The two sets of movable seats 3 can be adjusted to change the distance between them and the corresponding fixed seats 4 to adapt to welding workpieces of different lengths.

[0023] like Figure 2As shown, the upper surfaces of each movable seat 3 and each fixed seat 4 are arc-shaped, and multiple groups of rollers 401 are distributed along the arc, and the axes of each roller 401 overlap in the horizontal direction.
