[0002] Welding equipment is widely used, especially for welding various metal pipes, metal profiles and parts. Basically, the workpiece to be welded is placed on the platform of the welding equipment for welding. Among them, profiles are usually made of aluminum alloy or steel.

When welding profiles, positioning equipment and welding equipment are generally required to cooperate.

[0003] The existing conventional profile welding equipment directly adopts a clamp for clamping, and then uses a welding machine for welding. However, when stacking and welding long profiles, the positioning and fixing between the profiles is not convenient enough and requires manual cooperation. In addition, the fixed position between the two profiles is prone to displacement, which affects the welding effect. Therefore, the utility model provides an automatic welding device.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution for automatic welding equipment: an automatic welding equipment, comprising a bracket 1 and a welding table 2 fixedly arranged on the top of the bracket 1, two slide rails 3 are symmetrically installed on one side of the upper surface of the welding table 2, and a welding gun moving seat 4 is commonly connected to the two slide rails 3, and two slide seats are installed on the lower surface of the welding gun moving seat 4 corresponding to the slide rail 3, and the welding gun moving seat 4 is slidably connected to the slide rail 3 through the two slide seats, and the welding gun moving seat 4 can be limited by the slide rail 3 to ensure the stability and safety of the welding gun moving seat 4 when moving;

[0020] A driving motor 7 and a vertical adjustment seat 51 are installed on the welding gun moving seat 4. The output end of the driving motor 7 is located below the welding gun moving seat 4 and is connected to a driving gear 71. The upper surface of the welding table 2 is located between the two slide rails 3 and is equipped with a rack 8. The driving gear 71 is meshed with the teeth on the surface of the rack 8. By controlling the driving motor 7 to rotate, the driving gear 71 is driven to move along one side (the side with the teeth) of the rack 8, thereby driving the welding gun 6 to weld and fix each point of the profile;

[0021] like Figure 1 As shown, a plurality of protective covers 10 and a plurality of positioning seats 9 are installed at equal intervals on the other side of the upper surface of the welding table 2, and a positioning cylinder 11 is installed in each protective cover 10. The telescopic end of the positioning cylinder 11 is connected to an extrusion block 12, and a magnet 14 is installed on the top surface of the positioning seat 9 and the lower end of one side of the corresponding extrusion block 12. Before welding, the first profile (i.e., the bottom profile) is placed on the supporting top block 13, and the supporting top block 13 is used to support the bottom profile, and at the same time, the magnet 14 at the lower end of one side of the positioning seat 9 is used to adsorb and position the bottom profile. Then, the positioning cylinder 11 is controlled to extend, and the extrusion block 12 is pushed to extrude and fix the other side of the bottom profile, thereby completing the fixation of the bottom profile. Then, the second profile (i.e., the top profile) is directly stacked on the bottom profile. At the same time, the magnet 14 on the top of the positioning seat 9 can be used to adsorb and fix the top profile. As a result, when the top profile is stacked on the bottom profile, it is positioned by its own gravity on the one hand, and by the adsorption of the magnet on the other hand, so that it is convenient for the welding gun 6 to weld and fix the two profiles.

[0022] like Figure 1 and 3 As shown, the upper surface of the welding table 2 is located at a plurality of locating seats 9 and a plurality of protective covers 10 at equal intervals, and a plurality of supporting top blocks 13 are arranged. The plurality of supporting top blocks 13 are on the same horizontal line, and the supporting top blocks 13 are threadedly connected to the welding table 2. The height of the supporting top blocks 13 can be adjusted by screwing the threads, thereby ensuring the stability and horizontality of the placement of the bottom profile.

[0023] like Figure 1 and 2 As shown, a transverse adjustment seat 5 is installed on the top of the vertical adjustment seat 51, and an adjustment hole is provided on the upper end surface of the vertical adjustment seat 51. One end of the transverse adjustment seat 5 is fixed to the vertical adjustment seat 51 by a bolt passing through the adjustment hole. Through the cooperation of the vertical adjustment seat 51 and the adjustment hole, the position of the transverse adjustment seat 5 in the vertical direction can be adjusted, that is, the height of the welding gun 6 can be adjusted. An adjustable welding gun 6 is installed at one end of the transverse adjustment seat 5, and an adjustment hole is also provided at the other end of the transverse adjustment seat 5. The welding gun 6 and the transverse adjustment seat 5 are also fixed by a bolt passing through the adjustment hole. By utilizing the cooperation of the transverse adjustment seat 5 and the adjustment hole, the position of the welding gun 6 in the horizontal direction can be adjusted, thereby improving the welding efficiency of the welding gun 6.

[0024] The working principle of the utility model is as follows: firstly, the bottom profile is placed on the supporting top block 13, and the supporting top block 13 is used to support the bottom profile, and at the same time, the magnet 14 at the lower end of one side of the positioning seat 9 is used to adsorb and position the bottom profile, and then the positioning cylinder 11 is controlled to extend, and the extrusion block 12 is pushed to extrude and fix the other side of the bottom profile, thereby completing the fixing of the bottom profile;

[0025] Then, the top profile is directly stacked on the bottom profile. At the same time, the top profile can be adsorbed and fixed by the magnet 14 on the top of the positioning seat 9, thereby completing the positioning of the two profiles to be welded.

[0026] Furthermore, according to the height of the welding point of the profile, the vertical and lateral positions of the welding gun 6 are adjusted, and then the driving motor 7 is controlled to rotate to drive the driving gear 71 to move along one side of the rack 8. While moving, the sliding seat and the slide rail 3 at the bottom of the welding gun moving seat 4 are used to limit the stability of the welding gun 6 during movement. Furthermore, the welding gun 6 can be used to weld and fix each point at the connection of the two profiles.

[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
