[0002] Stainless steel, full name stainless acid-resistant steel, refers to a series of steel types with high chemical stability in air, water, aqueous solutions of salts, acids, and other corrosive media; it is an alloy steel containing more than 13% chromium, and some also contain other elements such as nickel and titanium. Stainless steel has characteristics such as corrosion resistance and heat resistance. Its corrosion resistance decreases with the increase of carbon content, and the carbon content of most stainless steels is relatively low, with a maximum not exceeding 1.2%. It is a very widely used elevator decoration material, which can be selected for landing doors, door frames, door lintels, car doors, and car walls, etc. However, during the use of stainless steel, in order to improve its practicability, welding treatment is often required for stainless steel. However, during the welding process, in order to improve the welding effect, external welding positioning devices are often needed for auxiliary treatment. However, when the existing welding positioning devices are in use, there are still some problems:

[0003] Poor positioning effect. When the existing stainless steel welding positioning device performs positioning treatment on it, due to the poor overall adjustability, for the positioning treatment of stainless steel with different welding requirements, it often cannot be effectively satisfied, resulting in a poor positioning effect of the welding positioning device and unable to perform positioning treatment according to actual needs.

[0021] Embodiment 1:

[0022] A positioning device for welding the corners of a stainless steel frame. This embodiment is based on plastic products with a density greater than that of water. In order to achieve the cleaning of impurities, such as Figures 1-3 As shown, it includes a frame body 1. On one side outer wall of the bottom of the frame body 1, symmetrically distributed guide rails 2 are fixed by bolts, and guide blocks 3 are slidably inserted into the inner walls of the guide rails 2. The top outer wall of the guide block 3 is welded with a first support platen 4, and a sliding rail 9 is connected to the bottom of the frame body 1. A sliding block 10 is slidably inserted into the inner wall of the sliding rail 9, and a guide screw rod 11 is screwed in the center of the sliding block 10. The top of the sliding block 10 is fixed by bolts with a servo motor 12, and the output shaft of the servo motor 12 is provided with a second support platen 13;

[0023] By placing the segmented stainless steel on the support platen and cooperating with the position-adjustable positioning pressure plate 16, the stainless steel can be effectively squeezed and positioned, which can avoid the displacement of the stainless steel during the welding process and improve the welding accuracy.

[0028] When this embodiment is in use, first place the stainless steel to be welded under the positioning pressure plate 16, then rotate the threaded rod 15 to drive the positioning pressure plate 16 to press down, so as to squeeze and fix the stainless steel. After the squeezing and fixing is completed, according to the actual welding requirements, use the electric telescopic rod 6 at the bottom to drive the first support plate 4 to adjust the height position. After meeting the welding requirements of the second support plate 13, use the servo motor 12 to drive the second support plate 13 to rotate and adjust, so that the ends of the two stainless steel bodies are in contact with each other, and then use an external welding device to weld the stainless steel at the ends, so as to meet different welding requirements for processing.
