Existing automated brazing equipment often uses turntable brazing machines and flat structure brazing machines. However, such equipment occupies a large area, and a large amount of harmful gases will be generated during welding, which cannot be recovered. What kind of factors will appear in the brazing mechanism is mainly related to the welding method, the material to be welded and the shielding gas, and its intensity is affected by the welding specifications. A large amount of electric welding fume will be generated during the fusion welding process. It includes smoke and dust, mainly ozone, nitrogen oxides, carbon monoxide and hydrogen fluoride. Therefore, a vertical pipe induction brazing machine is proposed to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0017] according to Figure 1 , Figure 2 and Figure 3As shown, a vertical pipe induction brazing machine includes a main box body 3 and a frame body 1. A mounting bracket 8 is arranged on a rotating platform 15 installed in the main box body 3, so that the mounting bracket 8 is driven to rotate by the rotating platform 15. Air claws 12 arranged in four directions are arranged in sequence from bottom to top in the mounting bracket 8, so that the pipe fittings are clamped by the air claws 12, and the adjacent air claws 12 have different directions. The frame body 1 is respectively arranged on the left and right sides of the main box body 3, and the frame body 1 is connected with the main box body 3. Lifting mechanisms are respectively arranged in the frame body 1. A mechanical arm 6 is installed on the lifting mechanism in the frame body 1 on the left side of the main box body 3, and a high-frequency welder 13 is installed on the lifting mechanism in the frame body 1 on the right side of the main box body 3. The mechanical arm 6 and the high-frequency welder 13 are driven up and down by the lifting mechanism. The mechanical arm 6 has the function of loading and unloading. The shell moves the assembled pipe fitting to the position of the air claw 12 and clamps it by the air claw 12. Otherwise, the pipe fitting can be removed from the position of the air claw 12. The induction coil of the high-frequency welder 13 can weld the joints of the assembled pipe fittings.

[0018] The design uses a special design mechanism of the air gripper 12 and the mounting bracket 8 to clamp the pipe fittings vertically and weld them in sequence, which greatly saves floor space.

[0019] A movable slide 14 is installed on the lifting mechanism located in the frame 1 on the right side of the main box body 3, and a high-frequency welding machine 13 is slidably set on the movable slide 14, and the moving direction of the high-frequency welding machine 13 is directly opposite to the mounting bracket 8, so that the induction coil of the high-frequency welding machine 13 can smoothly approach the connection of the pipe fittings to heat the welding object to a certain temperature through the induction current to melt the solder and connect the pipe fittings.

[0020] A turntable 10 is provided in the main box 3 and is arranged opposite to the rotating platform 15. The turntable 10 is connected to the mounting bracket 8. The turntable 10 rotates synchronously with the rotating platform 15. The setting of the turntable 10 is beneficial to ensure the stability of the mounting bracket 8 during rotation.

[0021] A harmful gas filter box 4 for filtering the air in the main box 3 is provided on the top of the main box 3. The harmful gas filter box 4 can filter the harmful gas generated during welding to avoid the harm of the harmful gas to the operator's body and create a good production environment. The harmful gas is a rising gas, and the harmful gas filter box 4 is installed on the top of the main box 3, which is beneficial to the filtering of the harmful gas by the harmful gas filter box 4.

[0022] The lifting mechanism includes a lifting seat 5 and a driving motor 9 installed on the frame 1. The output end of the driving motor 9 is connected to one end of a screw 11 located in the frame 1 to drive the screw 11 to rotate. The other end of the screw 11 is rotationally connected to the frame 1, and the screw 11 is threadedly connected to the lifting seat 5 to drive the lifting seat 5 to move up and down. The two ends of the lifting seat 5 are respectively slidably set on the guide rails 7 installed in the frame 1. The guide rails 7 play a guiding role. The lifting seat 5 is used to install a robotic arm 6 or a high-frequency welding machine 13.

[0023] A viewing window 2 is provided on the main box body 3 , through which the welding condition inside the main box body 3 can be observed.

[0024] Working principle: first, the screw rod 11 is driven by the driving motor 9 to rotate and drive the lifting seat 5 to move up and down, and the pre-assembled pipe fittings are moved to the clamping station by the mechanical arm 6, and the pipe fittings are clamped separately by the air claws 12 on the clamping station, or they can be clamped by the upper and lower air claws 12 in combination. After the air claws 12 on one side of the mounting bracket 8 have clamped the pipe fittings, the rotating platform 15 drives the mounting bracket 8 to rotate, and clamps the pipe fittings on the air claws 12 facing other sides of the mounting bracket 8 in turn, and the screw rod 11 is driven by the driving motor 9 to rotate and drive the lifting seat 5 to move up and down, so that the high-frequency welder 13 moves up and down synchronously, and the rotating platform 15 rotates so that the air claws 12 are facing the high-frequency welder 13 in turn, and the induction coil on the high-frequency welder 13 moves to the joint of the pipe fittings in turn for welding. At the same time, the high-frequency welder 13 is controlled to move back and forth by the moving slide 14, so as to ensure that the induction coil moves smoothly to the welding position of the pipe fittings. During this welding process, the harmful gas filter box 4 filters the harmful gas generated during the welding process.
