[0002] An elevator is a vertical lift that serves several floors in a building. It has a car whose size and structure are convenient for passengers to enter and exit or load and unload goods. Regardless of its driving method, the elevator is a general term for vertical transportation tools in a building. In the production process of the elevator car, elevator stainless steel plates are needed. Some elevator stainless steel plates are small in size and need to be welded together with another elevator stainless steel plate to form a whole plate that meets the specifications for use, avoiding material waste.

At the same time, impurities are attached to the edge parts of the plates to be welded, which is inconvenient to clean and is not conducive to improving the welding quality. Therefore, in order to solve the above problems, a welding device for elevator plates is proposed. Summary of the invention

[0023] See also Figure 1-7 As shown, a welding device for elevator plates includes an electric welder 1, an inner toothed belt 2, a plurality of edge processing mechanisms 210 distributed and connected to the inner toothed belt 2, a driving gear 3, a table 5, a linear motor 611, a ceramic side pressure strip block 8 and a U-shaped hanger 9, two welding gun heads 110 connected to the electric welder 1 are respectively installed at the output ends of the two first oil cylinders 120, and the output end of the first oil cylinder 120 located between the two second oil cylinders 130 is installed with a U-shaped hanger 9, the linear motor 611 is installed on the inner top wall of the U-shaped hanger plate 610, and the two ends of the U-shaped hanger plate 610 are respectively installed at the two ends of the top of the table bracket 6, and a gap is left between the top surface of the U-shaped hanger plate 610 and the bottom of the electric welder 1, the cylinder end of the first oil cylinder 120 and the cylinder end of the second oil cylinder 130 are both fixedly connected to the bottom of the pulling connector 612 located on the linear motor 611, and the two sides of the pulling connector 612 are fixedly connected to the bottom of the electric welder 1 through a connecting structure; Combination Figure 7 As shown, when welding is performed on the gap between two plates 10 to be welded, the linear motor 611 drives the electric welder 1, the first cylinder 120 and the second cylinder 130 connected by the pulling connector 612 to move from one end to the other end. At the same time, one of the first cylinders 120 is in an extended state, so that the welding gun head 110 connected to the output end of the first cylinder 120 is close to the part to be welded and welding is performed, thereby completing the welding process of the elevator plate.

[0024] like Figure 1 , Figure 3, Figure 4 and Figure 7 As shown, the edge processing mechanism 210 includes a cleaning disc 211, a slider 212, a U-shaped support 213, a side guide hole 214 and a spring 215. The middle part of the cleaning disc 211 is rotatably installed between the two sliders 212, and the two sliders 212 are respectively slidably connected with the side guide holes 214 on both sides of the U-shaped support 213. The bottom of the slider 212 is connected to the bottom end of the side guide hole 214 through a spring 215. The bottom of the U-shaped support 213 is fixedly connected to the corresponding part of the inner toothed belt 2. The cleaning disc 211 partially exceeds the welding station strip hole 510, and the welding station strip hole 510 is opened in the middle of the table 5. The local surfaces on both sides of the cleaning disc 211 are in contact with the side edges of the two plates 10 to be welded, and the weld spacing between the edges of the two plates 10 to be welded is greater than the width of the ceramic side pressure strip block 8. The two sides of the cleaning disc 211 are not limited to a structural form of bristle distribution. When two plates to be welded are placed flat on the table 5 and need to be aligned, the portion of the cleaning disc 211 that extends beyond the welding station bar hole 510 is used as an alignment stop structure, and combined with multiple cleaning discs 211 on the same straight line, the neatness of the placement of the two plates 10 to be welded to form the weld is ensured.

[0026] Combination Figure 5 and Figure 6 As shown, a short shaft is installed on the convex block part located in the middle of the ceramic side pressure strip block 8, and one end of the short shaft is connected to the reduction motor 910 located on one side of the U-shaped hanger 9, and the bottom of the ceramic side pressure strip block 8 contacts the corresponding opposite edge processing mechanism 210 by moving; Before the welding gun head 110 performs mobile welding, the reduction motor 910 drives one end of the ceramic side pressure strip block 8 connected via the short shaft to rotate downward, so as to press the cleaning disc 211 below the inner side of one end of the ceramic side pressure strip block 8 into the U-shaped support 213 under the action of the spring 215. At the same time, combined with the ceramic side pressure strip block 8 that moves simultaneously with the welding gun head 110, it is beneficial to orderly move the cleaning disc 211 away from between the two plates 10 to be welded, thereby providing an unobstructed welding environment for the mobile welding of the welding gun head 110. When a certain point is welded, the lower part of the welded relatively low temperature point before the point contacts the annular surface of the cleaning disc 211 reset by the spring 215; When the elevator plate is welded, the elevator plate is turned over, and the straight weld welding part is placed at the welding station bar hole 510, and the straight weld welding part is in contact with the annular surface of the cleaning disc 211.

[0028] like Figure 1 and Figure 7 As shown, a carrier block 710 is slidably installed in the side groove 520, and an electromagnet 720 is embedded and installed on the surface of the carrier block 710. One side of the carrier block 710 is connected to the output end of the push-pull cylinder 7 connected to the outer end of the side groove 520. The electromagnet 720 and the push-pull cylinder 7 can be used to complete the position movement and fixation of the plate 10 to be welded.

[0029] Furthermore, a strip-shaped protective cover 410 is installed at the bottom of the gear carrier 4 , and the strip-shaped protective cover 410 surrounds the inner toothed belt 2 and the edge processing mechanism 210 connected to the inner toothed belt 2 .

[0030] Furthermore, the table top 5 is installed on the top of the table bracket 6, and side grooves 520 are distributed on the front and rear parts of the surface of the table top 5.

At the same time, combined with the ceramic side pressure strip block 8 that moves simultaneously with the welding gun head 110, it is beneficial to orderly move the cleaning disc 211 away from between the two plates 10 to be welded, thereby providing an unobstructed welding environment for the mobile welding of the welding gun head 110. When a certain point is welded, the lower part of the welded relatively low temperature point before the point contacts the annular surface of the cleaning disc 211 reset by the spring 215; When the elevator plate is welded, the elevator plate is turned over, and the straight weld seam welding part is placed at the welding station bar hole 510, and the straight weld seam welding part is in contact with the annular surface of the cleaning disc 211. When the elevator plate is fixed, the servo motor is driven to drive a corresponding driving gear 3 to rotate, so that the inner toothed belt 2 and the connected edge processing mechanism 210 connected in meshing transmission are in a high-speed operation state, so that the cleaning disc 211 in the edge processing mechanism 210 moves quickly, which plays a role in surface treatment of the weld seam welding part; The distributed support gears 12 can support the corresponding parts of the inner toothed belt 2 and prevent the inner toothed belt 2 from sagging, thereby ensuring the stability of the position movement of the cleaning disc 211.
