[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4This utility model provides a technical solution: a double-headed arc welding machine, including: a workbench 1, an electric welding machine 2 fixedly connected to the inner wall of the workbench 1, and a pressing structure 3, the outer wall of the bottom of the pressing structure 3 being fixedly connected to the outer wall of the top of the workbench 1, and a module structure 4 being fixedly connected to the outer wall of the top of the workbench 1; the module structure 4 includes a connecting seat 41, a lower welding head 42 fixedly connected to the inner wall of the bottom of the connecting seat 41, a positioning pin 43 fixedly connected to the inner wall of the bottom of the connecting seat 41, a mold base 44 slidably connected to the inner wall of the connecting seat 41, a positioning hole 45 opened on the outer wall of the bottom of the mold base 44, and fixing holes 46 symmetrically opened on the outer wall of the side of the mold base 44, a threaded rod 47 rotatably connected to the outer wall of the connecting seat 41, a fixing plate 48 threadedly connected to the outer wall of the threaded rod 47, and fixing rods 49 symmetrically fixedly connected to the outer wall of the fixing plate 48.
[0025] Positioning pins 43 are arranged in an array along the inner wall of the bottom of the connecting seat 41. The outer wall of the positioning pins 43 is slidably connected to the inner wall of the positioning hole 45. The outer wall of the bottom of the connecting seat 41 is fixedly connected to the outer wall of the top of the workbench 1. A suitable mold base 44 is selected and installed into the connecting seat 41. Since the positioning pins 43 are arranged in an array along the inner wall of the bottom of the connecting seat 41, and the outer wall of the positioning pins 43 is slidably connected to the inner wall of the positioning hole 45, when the mold base 44 is placed into the connecting seat 41, the positioning pins 43 can be inserted into the positioning hole 45, which plays a preliminary positioning role.
[0026] The outer wall of the lower welding head 42 is slidably connected to the inner wall of the mold base 44, and the outer wall of the fixing rod 49 is slidably connected to the inner wall of the connecting seat 41 and the fixing hole 46. When the threaded rod 47 is rotated, the threaded rod 47 is threadedly connected to the fixing plate 48. As the threaded rod 47 rotates, the fixing plate 48 will move on the threaded rod 47. Because the fixing rod 49 is symmetrically fixedly connected to the outer wall of the fixing plate 48, and the outer wall of the fixing rod 49 is slidably connected to the inner wall of the connecting seat 41 and the fixing hole 46, when the fixing plate 48 moves, the fixing rod 49 will be inserted into the fixing hole 46, thereby firmly fixing the mold base 44 in the connecting seat 41.
[0027] The pressing structure 3 includes a support frame 31, a hydraulic rod 32 is fixedly connected to the outer wall of the top of the support frame 31, a pressing plate 33 is fixedly connected to the outer wall of the bottom of the hydraulic rod 32, an upper welding head 34 is fixedly connected to the inner wall of the pressing plate 33, a guide rod 35 is fixedly connected to the outer wall of the top of the pressing plate 33, an exhaust pipe 36 is fixedly connected to the inner wall of the side of the support frame 31, and an exhaust fan 37 is fixedly connected to the outer wall of the exhaust pipe 36.
[0028] The outer wall of the guide rod 35 is slidably connected to the inner wall of the top of the support frame 31, ensuring the stability of the lower pressure plate 33 in the vertical direction. The outer walls of the bottom of the support frame 31 and the exhaust fan 37 are fixedly connected to the outer wall of the top of the workbench 1. During the welding process, the exhaust fan 37 works and extracts and discharges the fumes and exhaust gases generated during the welding process through the exhaust pipe 36, keeping the working environment clean.
[0029] The outer wall at the bottom of the lower pressure plate 33 contacts the outer wall at the top of the connecting seat 41. The lower pressure plate 33 is positioned above the connecting seat 41. When the outer wall at the bottom of the lower pressure plate 33 contacts the outer wall at the top of the connecting seat 41, the welding machine 2 is started. The upper welding head 34 and the lower welding head 42 are in a suitable welding position. The welding machine 2 uses a connecting line to enable the upper welding head 34 and the lower welding head 42 to perform double-head welding on the workpiece.
[0030] In use, the lower welding head 42 on the module structure 4 and the upper welding head 34 on the lower pressing structure 3 are connected to the welding machine 2 through the connecting line. The upper welding head 34 and the lower welding head 42 perform double-head welding on the workpiece through the connecting line of the welding machine 2.
[0031] First, select a suitable mold base 44 according to the corresponding welding parts, and install the mold base 44 into the connecting seat 41. Since the positioning pins 43 are arranged in an array along the inner wall of the bottom of the connecting seat 41, and the outer wall of the positioning pins 43 is slidably connected to the inner wall of the positioning hole 45, when the mold base 44 is placed into the connecting seat 41, the positioning pins 43 can be inserted into the positioning hole 45, which plays a preliminary positioning role. Then, rotate the threaded rod 47, which is threadedly connected to the fixing plate 48. As the threaded rod 47 rotates, the fixing plate 48 will move on the threaded rod 47. Since the outer wall of the fixing plate 48 is symmetrically fixedly connected with the fixing rods 49, and the outer wall of the fixing rods 49 is slidably connected to the inner wall of the connecting seat 41 and the fixing hole 46, when the fixing plate 48 moves, the fixing rods 49 will be inserted into the fixing hole 46, thereby firmly fixing the mold base 44 in the connecting seat 41.
[0032] Next, the welded part is placed in the groove on the mold base 44, and then the hydraulic rod 32 is activated. The hydraulic rod 32 pushes the lower pressure plate 33 to move downward. Because the upper welding head 34 is fixedly connected to the inner wall of the lower pressure plate 33, the upper welding head 34 will move downward with the lower pressure plate 33. The outer wall of the guide rod 35 is slidably connected to the inner wall of the top of the support frame 31, which ensures the stability of the lower pressure plate 33 in the vertical direction. When the outer wall of the bottom of the lower pressure plate 33 contacts the outer wall of the top of the connecting seat 41, the electric welding machine 2 is started. The upper welding head 34 and the lower welding head 42 are in a suitable welding position. The electric welding machine 2 enables the upper welding head 34 and the lower welding head 42 to perform double welding on the workpiece through the connecting line. During the welding process, the exhaust fan 37 works. The exhaust fan 37 extracts and discharges the smoke and exhaust gas generated during the welding process through the exhaust pipe 36 to keep the working environment clean.
[0033] After welding is completed, the hydraulic rod 32 moves in the opposite direction, driving the lower pressure plate 33 and the upper welding head 34 to move upward and return to the initial position, so that the welded part can be taken out and the welding is completed.
[0034] If different welding parts need to be welded, the mold base 44 needs to be replaced. The threaded rod 47 can be rotated to move the fixing plate 48 outward, the fixing rod 49 can be pulled out from the fixing hole 46, the mold base 44 can be removed, and then the new mold base 44 can be installed and the above fixing steps can be repeated.
