Description

Technical Field

[0001] The invention relates to the technical field of automatic welding equipment, in particular to a full-automatic copper pipe welding equipment. Background Art

[0002] Copper pipe welding equipment is a tool and equipment specially used to connect copper pipes. It heats the filler metal (solder) to melt and flow into the gap between the copper parts to be connected, and forms a strong joint after cooling. This type of equipment is widely used in refrigeration, air conditioning systems, pipeline engineering and other fields.

[0003] Related technology can refer to the patent with announcement number CN213163937U, which discloses a fully automatic copper tube welding device, including: a workbench, the workbench is equipped with a rotary welding structure; the rotary welding structure includes: a pair of drive boxes, a pair of rotating motors, a pair of first gears, a pair of bearings, a pair of fixing fixtures, a pair of shaft fixing blocks, a pair of rotating shafts, a pair of second gears, a pair of transmission chains, a welding support table, a rotating table and a welding manipulator; the patented technical solution solves the problem that the existing copper tube welding is that the staff manually welds the welds with a handheld welding gun, which is cumbersome to operate and has a slow processing speed. The staff needs to weld little by little. When the amount to be welded is large, the workload is large and multiple workers are required to weld, which increases production costs, poor production quality and slow production speed.

[0004] With respect to the above-mentioned related technologies, when welding the copper tubes to be connected, the welding gun is usually used for horizontal welding. Since the welding gun is directly facing the welding area, the heat will be more concentrated, which may cause local overheating, especially on thin-walled materials or materials with good thermal conductivity (such as copper tubes), which can easily cause burn-through or deformation. Therefore, a new type of fully automatic copper tube welding equipment is urgently needed to solve the above technical problems. Summary of the invention

[0005] In order to improve product quality and production efficiency, the invention provides a fully automatic copper pipe welding device.

[0006] The present invention provides a fully automatic copper tube welding device, which adopts the following technical solution: A fully automatic copper pipe welding device comprises a moving plate, two guide rails are horizontally arranged below the moving plate, the guide rails are extended along the length direction of the moving plate, two sliders are arranged on the lower end surface of the moving plate, the two sliders are arranged at the two ends of the moving plate opposite to each other, the sliders are slidably connected with the guide rails, a driving cylinder is arranged at one end of the moving plate, the piston rod of the driving cylinder is fixedly connected with the slider, a moving rod is vertically arranged on the upper end surface of the moving plate, a rotating rod is horizontally arranged on the end of the moving rod away from the moving plate, a placing frame is fixedly connected to the end of the rotating rod away from the moving rod, and the placing frame water It is arranged horizontally, and two relatively arranged placing rings are fixedly connected to the placing frame, and a number of welding guns are fixedly connected to the placing rings, and the welding guns are evenly distributed. A reciprocating mechanism for controlling the moving rod to move back and forth is arranged in the movable plate, and a positioning rod is vertically arranged at the end of the movable plate away from the driving cylinder, and the end of the rotating rod away from the placing frame is rotatably connected to the movable rod, and a sleeve is fixedly connected to the top of the positioning rod, and the rotating rod is located in the sleeve, and the rotating rod is threadedly connected to the sleeve, and a fixing assembly for fixing the copper tube is arranged at the end of the movable plate away from the driving cylinder, and the copper tube on the fixing assembly is located in the two placing rings.

[0007] By adopting the above technical solution, when copper tube welding is required, the staff first splices the copper tubes to be spliced ​​and then puts them on the fixed assembly, and then starts the driving cylinder, which pushes the movable plate forward along the guide rail direction, so that the welding gun on the placement ring is aimed at the welding point of the two copper tubes, and then starts the reciprocating mechanism, which drives the moving rod to move back and forth, thereby expanding the welding range of the welding gun, and while the moving rod moves back and forth, due to the connection relationship between the sleeve and the rotating rod, the position of the sleeve remains unchanged, and the rotating rod moves back and forth and rotates back and forth, thereby driving the welding gun on the placement ring to swing left and right, thereby changing the angle of the welding gun, ensuring that the copper tube welding point is evenly heated, which is beneficial to improving welding efficiency.

[0008] Optionally, the reciprocating mechanism includes a reciprocating rod and two driving half wheels, a driven wheel and a driving wheel are coaxially fixedly connected to the bottom of the two driving half wheels, a connecting wheel is meshed between the driven wheel and the driving wheel, a moving groove is provided on the upper end surface of the moving plate, the moving groove is extended along the length direction of the moving plate, the reciprocating rod is located at the moving groove, the two driving half wheels are relatively arranged at two ends of the reciprocating rod, a driving motor is provided on the lower end surface of the moving plate, the output shaft of the driving motor is coaxially fixedly connected to the driving wheel, the reciprocating rod is meshed with the driving half wheels, and the end of the reciprocating rod away from the driving cylinder is fixedly connected to the moving rod.

[0009] By adopting the above technical solution, when the reciprocating mechanism is needed to drive the moving rod to move back and forth, the staff starts the driving motor, and the driving motor drives the driving wheel to rotate, thereby synchronously driving the driven wheel to rotate with the assistance of the connecting wheel. The rotation of the driving wheel and the driven wheel will drive the two driving half wheels to rotate. Specifically, when the driving motor is started, the first driving half wheel rotates to drive the reciprocating rod to move forward.

The staff starts the water pump, and the water pump drives the water in the water tank to spray out from the water spray pipe, thereby achieving the cooling treatment of the copper tube welding point. The cooled water will remain in the protective wall of the chassis. The accumulated water will collect the waste generated during the welding process to prevent it from falling directly and causing damage to the equipment.

[0029] Reference Figure 1 , Figure 2 and Figure 4 When the copper tube 10 needs to be welded, the staff first splices the copper tube 10 to be spliced ​​and then puts it on the fixed component 2, and then starts the driving cylinder 12. The driving cylinder 12 pushes the moving plate 11 to move forward along the guide rail 111, so that the welding gun 13 on the placement ring 16 is aligned with the welding point of the two copper tubes 10, and then starts the reciprocating mechanism 17. The reciprocating mechanism 17 drives the moving rod 113 to move back and forth, thereby expanding the welding range of the welding gun 13, and while the moving rod 113 moves back and forth, due to the connection relationship between the sleeve 19 and the rotating rod 14, the position of the sleeve 19 remains unchanged, and the rotating rod 14 moves back and forth and rotates back and forth, thereby driving the welding gun 13 on the placement ring 16 to swing left and right, thereby changing the angle of the welding gun 13, ensuring that the welding point of the copper tube 10 is heated evenly, which is beneficial to improving the welding efficiency.
