Embodiment Construction
[0047] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
[0048] Such as Figure 1~Figure 13 As shown, the new automatic welding system suitable for heat exchangers includes a gas pressure control cabinet 1, a main control cabinet 2, a welding machine and an exhaust gas treatment machine 3, and the welding machine includes a base 4, a workpiece table 5 and a burning machine. Welding mechanism, the workpiece table 5 is an "L" shaped frame structure, the workpiece table 5 slides back and forth along the base 4 through the screw mechanism-6, that is, the workpiece table 5 slides along the length direction of the base 4, Such as Figure 4 shown.
[0049] Specifically, the screw mechanism one 6 is arranged on the base 4, and the screw mechanism one 6 includes a drive motor 7, a screw rod 8 connected to the drive motor 7, and guide rods 9 arranged on both sides of the screw rod 8. The motor 7 is a servo motor,...

The invention relates to a novel automatic welding system suitable for a heat exchanger. The system comprises a gas pressure control cabinet, a main control cabinet, a welding machine and a waste gas treatment machine, wherein the welding machine comprises a base, a workpiece table and a welding mechanism, and the heat exchanger is detachably connected to the workpiece table; the welding mechanism comprises welding units symmetrically arranged on the two sides of the base and a gas collecting hood, each welding unit comprises a maintenance platform, a main frame body, a welding gun base and a plurality of welding guns, and a distance sensor is further arranged on each welding gun base; and the gas collecting hood comprises side plates and an inverted-cone-shaped hood body, the side plates are arranged between the main frame bodies on the two sides in a rectangular surrounding manner, and the hood body communicates with the waste gas treatment machine. The heat exchanger can be driven to accurately move front and back, and meanwhile, the welding guns can be driven to accurately move up and down and left and right, so that the heat exchangers with different heights, different row numbers and different structural sizes can be continuously welded, the welding efficiency is effectively improved, the labor cost is reduced, and meanwhile, the welding quality is stable.
Description
technical field [0001] The invention relates to the technical field of welding equipment, in particular to a novel automatic welding system suitable for heat exchangers. Background technique [0002] The heat exchanger automatic welding machine is an automatic welding equipment applied to U-shaped tube welding, which connects the U-shaped elbow with two adjacent copper tubes to form a complete heat exchanger coil. [0003] Taking the heat exchanger for air conditioning units as an example, it is bulky, including the frame, the end plates arranged at both ends of the frame, a number of copper pipes fixed between the end plates at both ends, and the elbow connecting the corresponding two copper pipes. As well as several layers of cooling fins arranged between several copper tubes, in order to increase the strength of the heat exchanger, the edge of the end plate is also bent. [0004] The welding of the above-mentioned large-scale heat exchangers, traditional welding is mostl...
