Description

Technical Field

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

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Welding achieves the purpose of joining through three ways: fusion welding, pressure welding and brazing. At present, in the process of stainless steel welding, it is necessary to clamp and fix the two stainless steel workpieces to be welded by welding auxiliary devices before welding. The existing stainless steel welding auxiliary devices usually do not have a flipping function. When welding different sides of stainless steel materials, frequent disassembly and assembly are required to achieve welding of different sides, which is cumbersome and reduces welding efficiency.

[0003] For example, Chinese patent announcement No. CN214770065U discloses an auxiliary device for stainless steel welding. When in use, the stainless steel material to be welded is docked and placed between two fixed seats, and the second rotating shaft is driven by turning the turning handle to rotate the worm wheel, and the worm engaged with the worm wheel rotates, and the moving block is moved by the threaded transmission of the worm, and the clamping plate is pulled by the hinge rod to clamp and fix the stainless steel material, and welding can be performed after fixation. When different surfaces of the stainless steel material need to be welded, the first rotating shaft is driven to rotate by holding the crank handle, and the first toothed disc sleeved at both ends of the first rotating shaft follows the rotation, and the first toothed disc drives the second toothed disc to rotate through the transmission of the chain, and the two rotating columns follow the two second toothed discs to rotate synchronously, which can drive the clamping tool holding the stainless steel material to flip, thereby facilitating the welding of different surfaces of the stainless steel material, meeting the welding requirements of different surfaces, and being simple to operate and improving efficiency. The problem that the existing auxiliary device for stainless steel welding usually does not have a flipping function and needs to be frequently disassembled and assembled to achieve welding of different surfaces is cumbersome to operate and reduces welding efficiency is solved.

[0004] However, the auxiliary device for stainless steel welding in the above application can only perform flip welding on stainless steel materials of a specific length, and cannot be adjusted specifically according to the length of the stainless steel material. It has a limited scope of application and cannot provide a good clamping effect for cylindrical stainless steel. Therefore, it has certain limitations.

[0005] For this reason, we urgently need to provide an auxiliary device for stainless steel welding. Utility Model Content

[0006] The purpose of the utility model is to provide an auxiliary device for stainless steel welding to solve the problem that the auxiliary device for stainless steel welding proposed in the above-mentioned background technology can only perform flip welding on stainless steel materials of a specific length, cannot be specifically adjusted according to the length of the stainless steel materials, has a limited scope of application, and cannot provide a good clamping effect for cylindrical stainless steel.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary device for stainless steel welding, comprising a base plate and a support frame, wherein the two support frames are respectively installed on the left and right sides of the upper surface of the base plate, an adjustment device is arranged on the base plate, and a clamping device is arranged on the inner side of the support frame.

[0010] A further improvement is that the clamping device includes a turning unit, a clamping unit and a fixing unit.

[0014] A further improvement is that the fixing unit includes a guide rail, a guide rail seat, a U-shaped frame, a threaded rod, and a fixing plate, the guide rail being installed on one side of the inner outer surface of the mounting plate, the guide rail seat being slidably connected to the guide rail, the U-shaped frame being fixedly connected to one side of the guide rail seat, the threaded rod being threadedly connected to the top center of the U-shaped frame, and the fixing plate being fixedly connected to the bottom of the threaded rod.

[0015] A further improvement is that there are four groups of fixing units, and the four groups of fixing units are installed in pairs at the front and rear ends of the inner outer surfaces of the two mounting plates.
