Description
Technical Field
[0001] The utility model relates to the technical field of welding devices, in particular to a copper tube flame brazing device which is easy to fix. Background Art
[0002] Flame brazing is divided into flame hard brazing and flame soft brazing. Flame brazing uses the flame of a mixture of combustible gas and oxygen or compressed air as the heat source for welding. Flame brazing equipment is simple and easy to operate. Depending on the shape of the workpiece, multiple flames can be used for simultaneous heating and welding.
[0003] The existing patent with publication number CN2784122Y discloses a brazing structure of copper tube and aluminum tube, in which the copper tube and the aluminum tube are plugged together, and an intermediate filter brazing material layer is plated on the tube surface where the copper tube and the aluminum tube are plugged together, and the copper tube is welded to the aluminum tube through the brazing material layer.
[0004] Although the above patent realizes convenient operation and the brazing seam formed after welding can fully meet the requirements of the refrigeration system, it is similar to the traditional manual welding method. During the vertical welding process, generally only the pipe located below is fixed, which easily leads to inaccurate positioning problems. Moreover, this method is only convenient for single-side welding and inconvenient for welding on both sides. Based on this, we propose an improved copper tube flame brazing device that is easy to fix. Utility Model Content

[0023] Example 1
[0024] Combine Figures 1-4 A copper tube flame brazing device that is easy to fix includes an adjustment mechanism 1, the adjustment mechanism 1 includes a frame 11, a mounting block 14 is slidably provided on the frame 11, a positioning mechanism 2 is provided at the front end of the mounting block 14, and a rotating mechanism 3 is provided at the rear end of the mounting block 14;
[0025] The positioning mechanism 2 includes an adjusting frame 21, on which an adjusting clamp 24 is slidingly provided, and a fixed clamp 25 is fixedly connected to the lower end surface of the adjusting frame 21. Auxiliary pads 28 are fixedly connected to the circular holes of the adjusting clamp 24 and the fixed clamp 25 near the rear side. Adjusting screws 26 are threadedly connected to the adjusting clamp 24 and the fixed clamp 25, and the rear ends of the two adjusting screws 26 respectively pass through the adjusting clamp 24 and the fixed clamp 25 and are rotatably connected to a sliding pad 27.
[0026] See Figure 1 、 Figure 2 and Figure 4, it is further obtained that the two sliding pads 27 are respectively arranged opposite to the two auxiliary pads 28, and the front end surfaces of the two sliding pads 27 are fixedly connected with guide rods on both sides, and multiple guide rods are respectively set through the adjusting clamp 24 and the fixed clamp 25, and the adjusting frame 21 is respectively rotatably and fixedly connected with the screw rod 22 and the slide rod 23, and the adjusting clamp 24 is respectively threaded and slidably connected to the outer walls of the screw rod 22 and the slide rod 23.
[0027] Specifically, when the sliding pad 27 is driven to move by rotating the adjusting screw 26, the guide rod limiter can prevent the sliding pad 27 from rotating, and then the auxiliary pad 28 can be used to clamp and fix the pipe 4. At the same time, the motor is used to drive the screw rod 22 to rotate to drive the adjusting clamp 24 to rise and fall, thereby adjusting the distance between the two pipes 4 and facilitating the installation of joints of different lengths.
[0028] Example 2
[0029] See Figure 2 and Figure 3 , and on the basis of Example 1, it is further obtained that four positioning holes 15 are opened at the rear end of the mounting block 14, the rotating mechanism 3 includes an adjusting shaft 33, the adjusting shaft 33 is rotatably connected and arranged in the mounting block 14, and the front end of the adjusting shaft 33 is fixedly connected to the rear end surface of the adjusting frame 21, the rear end of the adjusting shaft 33 is fixedly sleeved with a rotating wheel 34, and a positioning pin 35 is slidably sleeved on the rotating wheel 34, and the front end of the positioning pin 35 is slidably sleeved in the positioning hole 15, and a circular plate 32 is fixedly sleeved on the outer wall of the rear end of the positioning pin 35, and a spring 31 is fixedly connected between the circular plate 32 and the rotating wheel 34, and the spring 31 is movably sleeved on the outer end of the positioning pin 35.
[0030] Specifically, the rotating wheel 34 can drive the adjusting shaft 33 to rotate, thereby driving the adjusting frame 21 to rotate, thereby facilitating flip adjustment during vertical welding. At the same time, the positioning pin 35 is sleeved on the positioning hole 15 to fix the angle of the rotating wheel 34 and prevent the adjusting frame 21 from shaking.
[0031] Example 3
[0032] See Figure 1 and Figure 4 On the basis of Example 1 and Example 2, it is further obtained that a screw rod 13 and a slide rod 12 are rotatably and fixedly connected respectively between the upper and lower plates of the frame 11 near the two sides, and one side of the mounting block 14 is threadedly connected to the outer wall of the screw rod 13, and the other side is slidably sleeved on the outer wall of the slide rod 12.
[0033] Specifically, the height of the mounting block 14 can be adjusted by rotating the screw rod 13 driven by the motor, thereby adjusting the overall height of the positioning mechanism 2 to facilitate connection to the pipe 4 below.
[0034] The adjusting screw 26 is used to rotate the adjusting screw 26 to drive the sliding pad 27 to move toward the auxiliary pad 28 to clamp the pipe 4. Then, according to the length of the joint between the two pipes 4, the adjusting clamp 24 is driven to rise and fall by rotating the screw rod 22, so that the joint can be sleeved on the two pipes 4 for welding. After welding on one side, the positioning pin 35 is pulled out of the positioning hole 15. Then, after the rotating wheel 34 is rotated 180°, the positioning pin 35 is sleeved in the positioning hole 15 located below and fixed, and prevented from falling out under the pressure of the spring 31. At this time, the adjusting shaft 33 will drive the adjusting frame 21 to rotate the same angle, swapping the upper and lower pipes 4, thereby facilitating welding of the interface on the other side. During the welding process, according to the length of the pipe 4 located below, the motor can be used to drive the screw rod 13 to rotate to adjust the height of the mounting block 14, thereby driving the positioning mechanism 2 to rise and fall, and adjusting the height of the fixed clamp 25.
