[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 6 As shown, a clamp for an automatic welding machine for flute-shaped pipes of air conditioners comprises a base 1, a movable clamping block 2 and a fixed clamping block 3 are respectively arranged at two ends of the top of the base 1, the fixed clamping block 3 is fixedly arranged on the top of the base 1, a telescopic cylinder 4 is arranged on one side of the movable clamping block 2 away from the fixed clamping block 3, and the telescopic cylinder 4 is fixedly arranged on the top of the base 1 through a fixing member;

[0029] A positioning plate 5 is provided above the base 1, and support plates 6 are slidably sleeved on both ends of the positioning plate 5, and the support plate 6 is slidably provided on the top of the base 1, and a spacing adjustment component 7 is provided on the back of the dynamic clamping block 2, and adjustment blocks 14 are slidably provided inside the dynamic clamping block 2 and the fixed clamping block 3, and springs 15 are provided between the top and bottom of the back of the adjustment block 14 and the inner walls of the dynamic clamping block 2 and the fixed clamping block 3;

[0030] The dynamic clamping block 2 and the fixed clamping block 3 are both provided with nitrogen charging heads. When the flute-shaped tube is placed between the dynamic clamping block 2 and the fixed clamping block 3 for clamping and fixing, the two nitrogen charging heads can be respectively inserted into the two ends of the flute-shaped tube. During welding, the nitrogen charging heads can discharge nitrogen, thus avoiding oxidation during welding of the pipe and the flute-shaped tube. By moving the telescopic cylinder 4, the operation time of the flute-shaped tube is shortened, thereby improving the welding efficiency of the flute-shaped tube.

[0031] When clamping and fixing the flute-shaped tubes with different outer diameters, the distance between the adjustment block 14 and the inner wall directly facing the dynamic clamping block 2 and the fixed clamping block 3 is adjusted by setting the spacing adjustment component 7, so that the outer side of the flute-shaped tube is in contact with the adjustment block 14 and the dynamic clamping block 2 and the fixed clamping block 3, ensuring the levelness of the two ends of the flute-shaped tube, avoiding the situation that the outer wall of the two ends of the flute-shaped tube is tilted due to the different spacing between the adjustment block 14 and the dynamic clamping block 2 or the fixed clamping block 3, thereby improving the welding effect between the flute-shaped tube and the pipe.

[0032] A plurality of evenly distributed first positioning holes 8 are provided at one end of the positioning plate 5 close to the dynamic clamping block 2, and a plurality of evenly distributed second positioning holes 9 are provided inside the positioning plate 5. When welding the flute-shaped tube to the piping, the first positioning holes 8 are used to position the vertical piping, and the second positioning holes 9 are used to position the curved piping.

[0033] like Figure 4 and Figure 5 As shown, the spacing adjustment assembly 7 includes two connecting members 71 and a telescopic member 72. The two connecting members 71 are respectively fixedly arranged on the back of the movable clamping block 2 and the fixed clamping block 3, and the two ends of the telescopic member 72 are respectively rotatably connected to the two connecting members 71;

[0034] Both ends of the telescopic member 72 are fixedly provided with a push block 73 and a connecting rod 74. A second positioning bolt 75 is provided on one side of the connecting rod 74 close to the connecting member 71. An arc groove 76 cooperating with the second positioning bolt 75 is provided at one end of the connecting member 71.

[0035] The telescopic member 72 is composed of a cross rod 721 and two sleeves 722. The two sleeves 722 are respectively slidably sleeved on both ends of the cross rod 721. The arrangement of the cross rod 721 and the two sleeves 722 makes the telescopic member 72 retractable. When adjusting the spacing between the movable clamping block 2 and the fixed clamping block 3, the rotation of the push block 73 will not be affected.

[0036] When adjusting the position of the adjustment block 14, first tighten the nut on the outside of the second positioning bolt 75 to loosen the connecting rod 74, then the telescopic member 72 can be rotated, the connecting rod 74 and the push block 73 rotate synchronously, and the adjustment block 14 is pushed by the push block 73 rotating clockwise, so that the adjustment block 14 can move forward, and the spring 15 is stretched under the force. When the push block 73 rotates counterclockwise, the adjustment block 14 moves backward under the action of the spring 15, thereby achieving the effect of adjusting the position of the adjustment block 14.

[0037] like Figure 2 As shown, a plurality of adjustment holes 10 are provided at both ends of the support plate 6, and two first positioning bolts 11 that cooperate with the adjustment holes 10 are provided at both ends of the positioning plate 5;

[0038] By tightening the nut on the outside of the first positioning bolt 11 and removing the first positioning bolt 11, the positioning plate 5 can be moved up and down along the support plate 6 to adjust the height of the positioning plate 5. After adjusting to a suitable height, the first positioning bolt 11 is inserted into the corresponding adjustment hole 10 to fix the positioning plate 5, so that the positioning plate 5 can position pipes at different heights.

[0039] like Figure 1 As shown, both ends of the top of the base 1 are provided with slide grooves 12, the bottoms of the two support plates 6 are slidably connected to the two slide grooves 12 respectively, and a locking bolt 13 is provided at one end of the bottom of the support plate 6;

[0040] By rotating the locking bolt 13 to loosen the support plate 6, the position of the support plate 6 can be adjusted forward and backward, so that the pipes in the flute-shaped pipe at different positions can be positioned.

[0041] The working principle of a clamp for an automatic welding machine for flute-shaped pipes of air conditioners provided by the utility model is as follows:

[0042] When in use, first adjust the position of the adjustment block 14 according to the outer diameter of the flute-shaped tube. After the adjustment is completed, place the flute-shaped tube between the dynamic clamping block 2 and the fixed clamping block 3, and make the mounting hole in the flute-shaped tube for inserting the pipe be located directly above. Then use the telescopic cylinder 4 to push the dynamic clamping block 2 to move left and right to fix the flute-shaped tube. After the fixation is completed, insert the pipe into the flute-shaped tube. For vertical pipes, place the outer side of the flute-shaped tube in the first positioning hole 8. For curved pipes, place the end away from the flute-shaped tube in the second positioning hole 9 for positioning. Different types of pipes can be adjusted accordingly as needed. After the pipes are positioned, the pipes can be welded between the flute-shaped tubes.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
