[0003] To improve production efficiency, our company uses robotic welding for the upper beam welding of elevator car frames, which is highly automated. However, after welding, manual removal of the weld slag with a small hammer is still required, resulting in additional labor costs and impacting production efficiency.

[0004] Therefore, in order to further improve production efficiency and automation, it is urgent to improve existing welding robots. Utility Model Content

The tertiary servo ball screw slide is fixed on the slide of the secondary servo ball screw slide, the secondary servo ball screw slide is fixed on the slide of the primary servo ball screw slide, and the mounting bracket is fixed on the slide of the tertiary servo ball screw slide.

[0010] Preferably, a shock-absorbing pad is provided between the impact hammer and the bearing plate, which can reduce the vibration transmission and impact of the impact hammer.

[0011] Preferably, in order to better contact the weld joint, the impact hammer is equipped with a flat-headed impact chisel, the ends of which are rounded on both sides.

[0012] In summary, this application includes at least one of the following beneficial technical effects: the welding device for welding the upper beam of the elevator car frame with slag removal function, by setting up a slag removal mechanism, after welding is completed, uses an impact hammer to hammer the slag at the weld joint, causing the slag to detach, and uses a Y-axis multi-stage extension arm to drive the impact hammer to move back and forth, so as to remove the slag from the entire weld. The slag removal effect is good, and it works in coordination with the welding arm, which greatly improves production efficiency and saves labor costs. Attached Figure Description

On the traveling trolley 37, the mounting bracket 34 is fixed on the Y-axis multi-stage extension arm 33, the servo linear guide slide 35 is vertically fixed on the mounting bracket 34, the bearing plate 38 is fixed on the slide of the servo linear guide slide 35, the impact hammer 36 is obliquely fixed on the bearing plate 38, the impact hammer 36 is mounted with a flat-head impact chisel 39, the ends of the flat-head impact chisel 39 are rounded on both sides, and a shock-absorbing pad is provided between the impact hammer 36 and the bearing plate 38. The shock-absorbing pad can reduce the vibration transmission and impact of the impact hammer 36.

[0018] Reference Figs. 1-2 A rack 4 is fixed to the side of the X-axis slide rail 31, and a gear that meshes with the rack 4 is fixed to the output end of the walking motor 32.

[0019] Reference Figs. 1-2 The Y-axis multi-stage extension arm 33 includes a first-stage servo ball screw slide 331, a second-stage servo ball screw slide 332, and a third-stage servo ball screw slide 333.

[0020] The walking motor 32, the servo linear guide slide 35, and the Y-axis multi-stage extension arm 33 are all connected to the computer control system.

[0021] The implementation principle of a welding device with slag removal function for welding elevator car frame upper beams according to an embodiment of this application is as follows:

[0022] After the elevator car frame upper beam and the sealing plate are combined, they are placed on the base 1. The welding arm 2 welds the elevator car frame upper beam and the sealing plate. After welding, the Y-axis multi-stage extension arm 33 extends and drives the impact cone to move above the weld. Then, the servo linear guide slide 35 drives the impact hammer 36 to move down to the set position. The impact cone drives the flat-head impact chisel 39 to hammer the weld slag, so that the weld slag can be quickly removed. In this process, the first-stage servo ball screw slide 331 first works to drive the second-stage servo ball screw slide 332 to move forward as a whole. Then the second-stage servo ball screw slide 332 works to drive the third-stage servo ball screw slide 333 to move forward. Finally, the third-stage servo ball screw slide 333 drives the impact cone to move forward until the entire weld slag is removed. Similarly, the traveling trolley 37 drives the Y-axis multi-stage extension arm 33 to move left and right. Each weld slag is removed by repeating the above actions.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
