Description

Technical Field

[0001] This invention relates to the field of air conditioner manufacturing technology, and in particular to an angle welding positioning device and its usage method. Background Technology

[0002] Currently, when welding the oil separator components of the super magnetic screw compressor, the on-site personnel manually assemble the components according to the assembly drawings. Because there are angle requirements for the assembly of the oil separator component's connecting pipes, this process is prone to assembly abnormalities when using traditional welding methods. It is difficult to ensure the accuracy of the angles. If there are problems with the relative positioning and welding dimensions, the welded oil separator will not align with the hole positions on the shell. It is necessary to disassemble the connecting pipes and reassemble them for welding. The disassembly and reassembly process can easily damage the shell of the main pressure-bearing components of the pressure vessel, posing serious quality and safety hazards.

[0003] During production, the relative positions, longitudinal and lateral distances, and sizes of the oil separator components and connecting pipes vary across different models, making on-site assembly difficult and severely impacting production efficiency. Therefore, there is an urgent need for a tooling system that facilitates precise assembly of oil separator components and connecting pipes. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide an angle welding positioning device and its usage method, so as to achieve zero deviation in the relative positioning size and angle size of the connecting pipe and the built-in oil separator assembly during the assembly and team formation process. The positioning device is easy to use and effectively improves welding efficiency, thereby solving the problems mentioned in the background art.

[0010] As a further improvement of the present invention: the width of the tooling groove matches the diameter of the connecting pipe, and the connecting pipe is snapped into the tooling groove.

[0011] As a further improvement of the present invention: the bottom of the fixing part and the bottom of the positioning part are fitted together on the top surface plane of the built-in oil separator assembly.

[0012] As a further improvement of the present invention: the top of the built-in oil separator assembly is provided with a baffle, and the baffle is provided with inlet and outlet water baffle holes.

[0013] As a further improvement of the present invention: the positioning part and the fixing part are made of tail material plate or stainless steel plate, and the thickness of the positioning part and the fixing part is 8mm.

[0014] As a further improvement of the present invention: the connector is a magnet, the magnet is fixedly mounted on the bottom of the fixing part, and the magnet is adsorbed and connected to the baffle on the top surface of the built-in oil separator assembly.
