Problems solved by technology

However, it is difficult to have an ideal positioning reference for special-shaped pipe fittings formed by cold plastic processing, and it is difficult to accurately ensure the assembly size only by mechanical positioning.
In addition, when assembling thin-walled parts, if the positioning accuracy is strictly guaranteed through fixtures, parts are easily deformed due to bumps and other reasons during loading and unloading

Abstract

The invention discloses special-shaped pipe fitting welding equipment. The special-shaped pipe fitting welding equipment comprises a workbench, a high-frequency sensing heating unit, an image measurement unit, a mechanical positioning and clamping unit, an exhaust fan and a control cabinet, wherein the exhaust fan is installed behind the mechanical positioning and clamping unit, the mechanical positioning and clamping unit is arranged in the middle of the tabletop of the workbench, and a PLC is installed in the control cabinet. The special-shaped pipe fitting welding equipment is applicable to assembling small-size special-shaped pipe fittings according to a soldering method, and the problem that high assembly accuracy can not be achieved when the positioning standard is not ideal is solved by the adoption of image measurement and positioning; meanwhile, errors caused by clamping force in the welding and heating process are compensated for conveniently and rapidly, welding accuracy is improved, and thin-wall positions of a part can be effectively prevented from collision deformation in the assembly or disassembly process.

Description

technical field [0001] The invention belongs to welding equipment, in particular to a special-shaped pipe fitting welding equipment. Background technique [0002] The process of assembling special-shaped pipe fittings by welding can produce parts with complex shapes and positions to meet special applications in the fields of energy, automobiles and electrical appliances. For welding assemblies of small-sized special-shaped pipe fittings with high sealing requirements but low load-bearing capacity requirements, they are generally processed by soft solder brazing on special welding equipment. [0003] The heating method of welding equipment is determined according to the material, size and welding requirements of the parts, such as high-frequency induction heating, laser heating, gas flame heating, etc. Compared with other methods, high-frequency induction heating has the advantages of cleanliness and safety, and is especially suitable for processing small-sized parts using s...
