[0028] Embodiment 1

[0029] Refer to Figures 1-4 , which is the first embodiment of the present utility model, and provides a reciprocating automatic welding device. Such a reciprocating automatic welding device includes a rack 1, the rack 1 is arranged in an inclined state with the left side high and the right side low, a control box 3 is welded on one side of the rack 1, a cross beam 2 is welded on the rear side of the top of the rack 1 through a bracket, and a lifting assembly 4 is slidably installed on the front side of the cross beam 2. The tail end of the lifting assembly 4 is fixedly connected to a linkage frame 21;

[0030] The movable end of the lifting assembly 4 is welded with a horizontal pipe 5. Two adjusting locks 6 are sleeved on the horizontal pipe 5. The clamping ends of the adjusting locks 6 are fixedly installed with welding torches 7. Welding machines 24 and pipe racks 25 are respectively installed on both sides of the top of the linkage frame 21, and the pipe rack 25 is located in front of the welding machine 24.

[0031] A first guide bar 23 is installed on the top of the cross beam 2, and a second slider that slides on the first guide bar 23 is installed at the bottom of the linkage frame 21.

[0032] A second guide bar 210 is installed on the front side of the cross beam 2. A first slider 28 is slidably installed on the second guide bar 210, and the first slider 28 is fixed on the side of the lifting assembly 4 close to the cross beam 2. A lead screw 29 is rotatably installed on the front side of the cross beam 2 and above the second guide bar 210 through a bearing. A transmission block 27 is threadedly driven on the lead screw 29, and a threaded hole threadedly connected to the lead screw 29 is opened on one side of the transmission block 27. The transmission block 27 is fixed on the side of the lifting assembly 4 close to the cross beam 2. A motor support plate 22 is welded on the side of the cross beam 2 close to the control box 3. A driving motor 26 for driving the rotation of the lead screw 29 is installed on the top of the motor support plate 22, and the driving end of the driving motor 26 is connected to the shaft end of the lead screw 29.

[0033] The lead screw 29 is driven to rotate by the drive motor 26. Under the action of the transverse screw drive between the lead screw 29 and the first slider 28, the lifting assembly 4 is driven to move by the first slider 28, thereby driving the welding torch to move, so that the welding torch welds the seam while moving. Two welding torches 7 are installed on the horizontal pipe 5, and the welding ends of the welding torches 7 are aligned with the seam. The welding torches 7 are driven to reciprocate along the seam, and the welding of two seams can be completed simultaneously at one time.

Under the action of the transverse screw drive between the lead screw 29 and the first slider 28, the lifting assembly 4 is driven to move by the first slider 28, thereby driving the welding torch to move, so that the welding torch welds the seam while moving. Two welding torches 7 are installed on the horizontal pipe 5, and the welding ends of the welding torches 7 are aligned with the seam. The welding torches 7 are driven to reciprocate along the seam, and the welding of two seams can be completed simultaneously at one time. The machine replaces manual welding, reducing the welding intensity and ensuring the welding quality of the workpiece, with high working efficiency.

[0037] Embodiment 2

[0038] Refer to Figures 1-4 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is:

[0039] The adjusting lock 6 includes a locking ring 61 installed on the horizontal pipe 5. A ball head rod 67 is rotatably installed on one side of the locking ring 61, and a fixture 69 for fixing the welding torch 7 is installed at the end of the ball head rod 67 away from the locking ring 61.

[0040] Both ends of the locking ring 61 are integrally formed with convex edges 62. Threaded holes are provided on the convex edges 62, and the two convex edges 62 are threadedly installed with a first butterfly bolt 63 through the threaded holes thereon. Unscrew the first butterfly bolt 63 from the convex edge 62 to reduce the friction between the locking ring 61 and the horizontal pipe 5, so that the locking ring 61 can move along the horizontal pipe 5. After the movement is completed, screw the adjusting lock 6 onto the threaded hole on the convex edge 62, so that the inner wall surface of the locking ring 61 fits against the outer wall surface of the horizontal pipe 5, increasing the friction between the locking ring 61 and the horizontal pipe 5, and fixing the locking ring 61 on the horizontal pipe 5. Thus, the distance between the two locking rings 61 on both sides can be adjusted to adapt to welding of two seams with different distances, with strong flexibility and high practicability.

[0041] A fixing block 64 is welded to one side of the outer wall of the locking ring 61. The top of the fixing block 64 is installed with a pressing block 65 through a bolt. Rotating grooves 66 are provided on the opposite surfaces of the fixing block 64 and the pressing block 65, and the two rotating grooves 66 form a rotating cavity for limiting the rotation of the ball head rod 67. The pressing block 65 is threadedly installed with a second butterfly bolt 68 through the threaded hole provided on its top, and the bottom end of the second butterfly bolt 68 abuts against the outer wall surface of the ball head rod 67.

[0042] The rotation of the ball head rod 67 can adjust the inclination angle of the welding torch 7. At the same time, the rotation of the locking ring 61 can also adjust the inclination angle of the welding torch 7. Therefore, the placement angle of the welding torch 7 can be adaptively adjusted according to actual use requirements.

[0043] During the use process, the process of fixing the adjusting lock 6 on the horizontal pipe 5 is as follows:

[0044] Unscrew the first butterfly bolt 63 from the convex edge 62 to reduce the friction between the locking ring 61 and the horizontal pipe 5, so that the locking ring 61 can move along the horizontal pipe 5. After the movement is completed, screw the adjusting lock 6 onto the threaded hole on the convex edge 62, so that the inner wall surface of the locking ring 61 fits against the outer wall surface of the horizontal pipe 5, increasing the friction between the locking ring 61 and the horizontal pipe 5, and fixing the locking ring 61 on the horizontal pipe 5;

[0045] Rotate the second butterfly bolt 68 upward to release the abutment between the second butterfly bolt 68 and the ball head rod 67, thus releasing the locking of the ball head rod 67. Rotating the ball head rod 67 can adjust the inclination angle of the welding torch 7. After the adjustment is completed, rotate the second butterfly bolt 68 in the reverse direction so that the second butterfly bolt 68 abuts against and locks the ball head end of the ball head rod 67 to fix the welding torch 7. At the same time, the rotation of the locking ring 61 can also adjust the inclination angle of the welding torch 7.

[0046] The remaining structure is the same as that of Embodiment 1.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them.
