[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0020] like Figure 1and Figure 2 As shown, this embodiment provides a swing-type automatic welding device, including a frame, a driving mechanism arranged on the frame, a crank slider mechanism arranged on the driving mechanism, and a welding gun arranged on the crank slider mechanism. The driving mechanism is used to drive the welding gun to move along the length direction of the weld, and the crank slider mechanism is used to drive the welding gun to reciprocate linearly along the width direction of the weld. The welding gun performs Z-shaped welding on the weld under the drive of the driving mechanism and the crank slider mechanism.

[0021] The swing-type automatic welding device in this embodiment drives the welding gun to move along the length direction of the weld by the driving mechanism, and drives the welding gun to move back and forth in a straight line along the width direction of the weld by the crank slider mechanism, so that the welding gun realizes Z-shaped welding of the weld under the drive of the driving mechanism and the crank slider mechanism. The weld of the Z-shaped welding is full and has clear lines. The weld height and weld width meet the process standards, and the weld strength is greatly improved, which greatly improves the welding quality, solves the problem of poor welding quality, and thus improves the welding yield.

[0022] The crank slider mechanism in this embodiment includes a rotary drive member 1, a fastening assembly 2, a first connecting rod 3, a second connecting rod 4, and a slider linear guide 5. The first connecting rod 3 is arranged parallel to the power output shaft 11 of the rotary drive member 1, and the first connecting rod 3 is fastened to the power output shaft 11 through the fastening assembly 2. One end of the second connecting rod 4 is hinged to the first connecting rod 3, and the other end of the second connecting rod 4 is hinged to the slider 51 of the slider linear guide 5. The welding gun is set on the slider 51. The setting of the crank slider mechanism realizes the remote operation and control of the welding gun, avoiding damage to other components during the welding process. In actual application, the crank slider mechanism can also be replaced by a telescopic cylinder or a telescopic electric cylinder. The specific selection is based on actual needs and this embodiment does not limit this.

[0023] The fastening assembly 2 in this embodiment includes a fastening sleeve 21 and a tightening bolt 22 threadedly connected to the side wall of the fastening sleeve 21. The fastening sleeve 21 is sleeved on the outside of the power output shaft 11 and the first connecting rod 3. The tightening bolt 22 and the first connecting rod 3 are located on opposite sides of the power output shaft 11, and the tightening bolt 22 passes through the fastening sleeve 21 and is tightened on the power output shaft 11.

[0024] In this embodiment, the length of the crank of the slider-crank mechanism can be changed by varying the thickness of the first connecting rod 3, thereby varying the swing amplitude of the welding gun, thereby meeting the requirements for welds of varying widths. This expands the scope of use of the swing-type automatic welding device and reduces welding costs. Specifically, the thicker the first connecting rod 3, the greater the swing amplitude of the welding gun, while the thinner the first connecting rod 3, the smaller the swing amplitude of the welding gun. The specific selection depends on the welding requirements and is not limited in this embodiment.

[0025] The welding gun in this embodiment is mounted on a welding gun adjustment bracket 6, which is mounted on a slider 51. The provision of the welding gun adjustment bracket 6 allows for adjustment of the welding gun's position and angle, further expanding the scope of use of the swing-type automatic welding device and meeting the welding requirements of various workpieces. The welding gun adjustment bracket 6 in this embodiment is a conventional structure. The accompanying drawings only illustrate a portion of the structure of the welding gun adjustment bracket 6 to illustrate its mounting position; its detailed structure is not detailed here.

[0026] The rotating drive member 1 in this embodiment is a motor. Since the stepper motor has good position accuracy and motion repeatability, the rotating drive member 1 in this embodiment is preferably a stepper motor. Such a setting improves the accuracy of weld seam welding.

[0027] The drive mechanism in this embodiment is a reciprocating linear motion drive mechanism. Due to the advantages of a screw slide with high transmission precision and strong load capacity, the reciprocating linear motion drive mechanism in this embodiment is preferably a screw slide. The screw slide is provided with a mounting seat, and the crank slider mechanism is mounted on this mounting seat. In actual applications, the reciprocating linear motion drive mechanism can also adopt a pneumatic slide or an electric cylinder. The specific selection depends on actual needs and is not limited in this embodiment.

[0028] When in use, the driving mechanism drives the welding gun to move along the length direction of the weld, and the crank slider mechanism drives the welding gun to reciprocate linearly along the width direction of the weld. The welding gun performs Z-shaped welding on the weld under the drive of the driving mechanism and the crank slider mechanism.

[0029] The above is only one embodiment of the swing-type automatic welding device of the utility model. There are many more embodiments that are not described here in detail. In summary, the swing-type automatic welding device of the utility model greatly improves the welding quality, solves the problem of poor welding quality, thereby increasing the welding yield rate. At the same time, it meets the use requirements of welds of different widths, expands the scope of use, and reduces welding costs.

[0030] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by ordinary technicians in this field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
