Description

Technical Field

[0001] The utility model relates to an automatic welding machine with an adjustable welding gun. Background Art

[0002] A ship is a means of transportation that can sail or anchor in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements. The ship plate is an important component of the interior of the ship. Welding work is inevitable during the production and processing of the ship plate to make it meet people's usage requirements. A large amount of heat is generated during the welding process of the ship plate, which can easily cause certain deformation at the weld of the ship plate, affecting the normal use of the subsequent ship plate. In order to reduce welding deformation, the existing technology adopts the method of setting a contraction seam at the welding position to provide space for the thermal expansion and contraction generated during the welding process. However, the welding gun in the existing welding equipment is mostly continuously moving, and it is not easy to avoid the contraction seam position. Manual adjustment of the welding position is required, which is extremely inconvenient. Utility Model Content

[0005] As a further improvement of the present invention, the cross section of the cross bar is square, the left side of the mounting and positioning seat is processed with an inclined surface, the rotary cylinder is installed on the inclined surface, the support rod forms an angle with the horizontal line, and the support rod tilts upward from right to left.

[0006] As a further improvement of the present invention, the positioning bracket is hingedly mounted on the end of the support rod through a pin and is locked with a locking nut.

[0015] like Figure 1-2 As shown, the utility model of an automatic welding machine with adjustable welding gun includes a mounting base 3, the upper part of the mounting base 3 is slidably arranged on the lower part of the lifting base 1 through a screw slider mechanism 2, the screw slider mechanism 2 includes a slider 21 fixedly mounted on the upper part of the mounting base 3, the upper part of the slider 21 is slidably matched with the lifting base 1 through a guide rail 23, the middle part of the slider 21 is threadedly connected to the screw rod 22, both ends of the screw rod 22 are mounted on the lower part of the lifting base 1 through a bearing seat 24, one end of the screw rod 22 is connected to the motor 25, and the left side of the mounting base 3 is installed. The rotating cylinder 4 is installed with a bevel 31 processed on the left side of the positioning seat 3. The rotating cylinder 4 is installed on the bevel 31. The support rod 5 forms an angle with the horizontal line. The support rod 5 tilts upward from right to left. One end of the support rod 5 is fixed to the output end of the rotating cylinder 4. The other end of the support rod 5 is installed with a positioning bracket 7. The end of the positioning bracket 7 away from the support rod 5 is provided with a welding gun 8. An angle is formed between the positioning bracket 7 and the support rod 5 and the angle is adjustable. The positioning bracket 7 is hingedly installed on the end of the support rod 5 through a pin shaft 6 and is locked with a locking nut 61.

[0016] This structure is mainly used for ship plate welding. During the welding process, the rotating cylinder is used to drive the welding gun to flip at intervals, thereby automatically avoiding the grooves on the parts to be welded, providing space for the thermal expansion and contraction of the parts to be welded during the welding process, effectively controlling and reducing welding deformation, and improving welding quality.

[0017] In order to facilitate understanding of the present invention, the following description will be given in conjunction with the accompanying drawings.

[0018] like Figure 4 The welded component 9 shown includes a first plate 91 and a second plate 92. A groove 93 is uniformly machined on one side of the second plate 92 for connection to the first plate 91. The groove 93 is mainly used to provide space for thermal expansion and contraction of the first plate 91 during welding. The groove 93 should be avoided during welding.

[0019] When welding, the first plate and the second plate are positioned, and the side of the second plate with the groove rests on the first plate, and the first plate and the second plate are both tilted; then, to adjust the angle of the welding gun, just loosen the locking nut, the positioning bracket drives the welding gun to rotate a certain angle with the pin shaft as the center, and locks the positioning with the locking nut, and the lifting seat moves down as a whole so that the welding gun is close to the connection between the first plate and the second plate, and the screw slider mechanism drives the installation positioning seat to move at a uniform speed in the front and rear directions as a whole, and the welding gun welds the connection between the first plate and the second plate. When the welding gun moves to the groove position, the rotating cylinder drives the support rod to rotate a certain angle, and the positioning bracket and the welding gun are flipped synchronously, and the welding gun is disengaged from the groove position. When the welding gun moves out of the groove position, the rotating cylinder drives the support rod to rotate and reset, and the welding gun is close to the connection between the first plate and the second plate again for welding;

[0020] The reason for setting an inclined surface and installing a rotating cylinder on the mounting base is mainly to consider on-site maintenance welding. The second plate is placed horizontally and its position is inconvenient to adjust. In order to allow the welding gun to smoothly avoid the groove position after flipping, the support rod is set at an angle, which has better overall versatility and is convenient for multi-angle welding.

[0021] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
