[0002] Welding of elevator sheet metal parts is a crucial step in elevator manufacturing, directly impacting the elevator's safety performance and lifespan. Elevator sheet metal parts mainly include car wall panels, door panels, and top and bottom frames. These components are typically made of steel or stainless steel plates, requiring good strength, corrosion resistance, and aesthetics.
[0003] During the welding process of sheet metal parts, they need to be clamped and fixed to ensure the subsequent welding quality. However, the existing fixtures on the processing table can only clamp sheet metal parts of a fixed size. When clamping sheet metal parts of different sizes or models, the fixtures need to be changed, which is cumbersome, time-consuming and labor-intensive. At the same time, after the existing fixtures clamp and fix the sheet metal parts, they cannot adjust the orientation according to the welding position. This means that the orientation of the sheet metal parts needs to be adjusted before clamping and fixing them. However, after clamping, the orientation of the sheet metal parts will inevitably change, which will affect the subsequent welding. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0024] The following provides a detailed description of the welding processing table for elevator sheet metal parts. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.
[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] Please see Figures 1-4 In this embodiment, an elevator sheet metal welding processing table is provided, including: a workbench 1, with two moving slots 101 on the top of the workbench 1, a moving block 104 slidably connected inside the moving slots 101, a fixed plate 2 fixedly connected to the top of the moving block 104, and a rotating plate 3 on the top of the fixed plate 2; a fixing assembly is provided on the rotating plate 3 for fixing the elevator sheet metal parts, the fixing assembly including: a clamping slot 301, a lead screw 302, a servo motor 303, a drive block 304 and a clamping plate 305; a rotating assembly is provided between the rotating plate 3 and the fixed plate 2 for changing the orientation of the rotating plate 3, the rotating assembly including: a rotating slot 201, a rotating motor 202, a drive wheel 203 and a driven wheel 204.
[0027] The device features a fixed component that can clamp and fix sheet metal parts of different sizes and models without requiring the replacement of the clamps, making it convenient and quick. It also increases the number of clamping points, improving clamping stability. Furthermore, the rotating component allows the orientation of the sheet metal parts to be adjusted according to their welding positions after clamping and fixing, avoiding errors caused by adjusting the orientation before clamping.
[0028] The rotating plate 3 has multiple clamping slots 301 on its top. A lead screw 302 is rotatably connected inside the clamping slot 301. Multiple servo motors 303 are fixedly installed on the outside of the rotating plate 3. Two drive blocks 304 are threadedly connected to the outside of the lead screw 302. A clamping plate 305 is fixedly connected to the top of the drive block 304. The multiple servo motors 303 correspond to the multiple clamping slots 301. One end of the lead screw 302 is connected to the drive shaft of the servo motor 303. The cross-sectional profile of the drive block 304 matches the cross-sectional size of the clamping slot 301.
[0029] The lead screw 302 has two threads in opposite directions, and the drive block 304 has a threaded hole that meshes with the lead screw 302. The two drive blocks 304 are located on the two threads on the lead screw 302 respectively, and a buffer pad 306 is fixedly connected to one side of the clamping plate 305.
[0030] When welding elevator sheet metal parts, the sheet metal parts need to be clamped and fixed to avoid positional displacement during the welding process, which would affect the welding quality. At this time, the sheet metal parts to be welded are placed on the rotating plate 3 and located between multiple clamping plates 305. Then, the servo motor 303 drives the lead screw 302 to rotate. Since the lead screw 302 has two threads with opposite directions, the two drive blocks 304 on the lead screw 302 move in opposite directions. In turn, the two drive blocks 304 drive the clamping plates 305 to move towards the sheet metal parts and clamp and fix the sheet metal parts.
[0031] By setting up multiple clamping plates 305, clamping slots 301 and servo motors 303, the clamping status of the clamping plate 305 on a certain lead screw 302 can be controlled individually. It can be adaptively adjusted according to the shape of the sheet metal part, so that multiple clamping plates 305 can firmly clamp and fix the surface of the sheet metal part, improve the clamping points of the sheet metal part, and improve the clamping stability.
[0032] The buffer pad 306 provides a certain degree of protection for the surface of the sheet metal parts, preventing the clamping plate 305 from leaving clamping marks on the surface of the sheet metal parts.
[0033] The fixed plate 2 has a rotating groove 201 inside, and a rotating motor 202 is fixedly installed inside the rotating groove 201. The top of the rotating motor 202 is connected to a drive wheel 203. The bottom of the rotating plate 3 is fixedly connected to a rotating rod 205. The bottom end of the rotating rod 205 extends into the rotating groove 201 and is fixedly connected to a driven wheel 204. Both the drive wheel 203 and the driven wheel 204 are gears, and the drive wheel 203 and the driven wheel 204 mesh with each other.
[0034] During the welding process of sheet metal parts, since the welding positions of different sheet metal parts are different, it is necessary to rotate the sheet metal parts and make the welding positions of the two sheet metal parts correspond. At this time, the drive wheel 203 can be driven to rotate by the rotary motor 202, so that the drive wheel 203 drives the rotating rod 205 to rotate through the driven wheel 204, and then drives the rotating plate 3 to rotate around the rotating rod 205 as the rotation center. After the sheet metal parts are clamped and fixed, their orientation can be changed so that the welding positions of the sheet metal parts on the two rotating plates 3 are opposite, which facilitates the subsequent welding operation.
[0035] The fixed plate 2 has an annular groove 4 on its top, and the rotating plate 3 has multiple rollers 401 fixedly installed at its bottom, with the rollers 401 located inside the annular groove 4.
[0036] During the rotation process, the rotating plate 3 is equipped with multiple rollers 401, which on the one hand makes the rotation of the rotating plate 3 smoother, and on the other hand supports the weight of the rotating plate 3, avoiding friction between the rotating plate 3 and the fixed plate 2, which would affect the rotation of the rotating plate 3.
[0037] The workbench 1 has a drive motor 103 fixedly installed on both the left and right sides. One side of the drive motor 103 is connected to a threaded rod 102, and one end of the threaded rod 102 extends into the moving groove 101 and is connected to the inner wall of the moving groove 101 through a bearing. The moving block 104 has a threaded hole that meshes with the threaded rod 102. The cross-sectional size of the moving block 104 matches the cross-sectional profile of the moving groove 101.
[0038] After the sheet metal parts are clamped and fixed and the welding positions are aligned, there is still space between the sheet metal parts on the two rotating plates 3. At this time, the threaded rod 102 can be rotated by the drive motor 103, so that the threaded rod 102 drives the moving block 104 to move in the moving groove 101 under the action of thread engagement, thereby driving the fixed plate 2, the rotating plate 3 and the sheet metal parts to move, so that the two sheet metal parts are brought closer to each other to facilitate welding operations.
[0039] Working principle:
[0040] When welding elevator sheet metal parts, the sheet metal parts need to be clamped and fixed to avoid positional displacement during the welding process, which would affect the welding quality. At this time, the sheet metal parts to be welded are placed on the rotating plate 3 and located between multiple clamping plates 305. Then, the servo motor 303 drives the lead screw 302 to rotate. Since the lead screw 302 has two threads with opposite directions, the two drive blocks 304 on the lead screw 302 move in opposite directions. In turn, the two drive blocks 304 drive the clamping plates 305 to move towards the sheet metal parts and clamp and fix the sheet metal parts.
[0041] By setting up multiple clamping plates 305, clamping slots 301 and servo motors 303, the clamping status of the clamping plate 305 on a certain lead screw 302 can be controlled individually. It can be adaptively adjusted according to the shape of the sheet metal part, so that multiple clamping plates 305 can firmly clamp and fix the surface of the sheet metal part, improve the clamping points of the sheet metal part, and improve the clamping stability.
[0042] The buffer pad 306 provides a certain degree of protection for the surface of the sheet metal parts, preventing the clamping plate 305 from leaving clamping marks on the surface of the sheet metal parts.
[0043] During the welding process of sheet metal parts, since the welding positions of different sheet metal parts are different, it is necessary to rotate the sheet metal parts and make the welding positions of the two sheet metal parts correspond. At this time, the drive wheel 203 can be driven to rotate by the rotary motor 202, so that the drive wheel 203 drives the rotating rod 205 to rotate through the driven wheel 204, and then drives the rotating plate 3 to rotate around the rotating rod 205 as the rotation center. After the sheet metal parts are clamped and fixed, their orientation can be changed so that the welding positions of the sheet metal parts on the two rotating plates 3 are opposite, which facilitates the subsequent welding operation.
[0044] During the rotation process, the rotating plate 3 is equipped with multiple rollers 401, which on the one hand makes the rotation of the rotating plate 3 smoother, and on the other hand supports the weight of the rotating plate 3, avoiding friction between the rotating plate 3 and the fixed plate 2, which would affect the rotation of the rotating plate 3.
[0045] After the sheet metal parts are clamped and fixed and the welding positions are aligned, there is still space between the sheet metal parts on the two rotating plates 3. At this time, the threaded rod 102 can be rotated by the drive motor 103, so that the threaded rod 102 drives the moving block 104 to move in the moving groove 101 under the action of thread engagement, thereby driving the fixed plate 2, the rotating plate 3 and the sheet metal parts to move, so that the two sheet metal parts are brought closer to each other to facilitate welding operations.

The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
