The top welding assembly 12 and the edge welding assembly 13 are located above the processing table 1.
[0022] In this embodiment, as Figure 1 and Figure 3 As shown, slide rods are fixedly connected to both ends of the horizontal lead screw 9 on one side of the processing table 1, and a through hole is opened at the bottom of the column 2 for sliding connection to the outer wall of the slide rod. The column 2 forms a horizontal transmission structure on one side of the processing table 1 through the helical transmission structure with the horizontal lead screw 9.
[0023] In this embodiment, as Figure 3As shown, the shaft at the center of the driven gear 8 is fixedly connected to the center of the bottom of the processing table 1, and the processing table 1 rotates horizontally around the center of the driven gear 8 below the top welding assembly 12 and the edge welding assembly 13 through the meshing transmission of the driving gear 7 and the driven gear 8.
[0024] In this embodiment, as Figure 2 As shown, the first reverse lead screw 3 and the second reverse lead screw 4 are arranged in a cross shape in the horizontal plane, and there is a gap between the first reverse lead screw 3 and the second reverse lead screw 4 above it.
[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the first inner liner assembly 5 and the second inner liner assembly 6 are both composed of two symmetrically distributed metal parts. The bottom of the metal parts is strip-shaped and the top end is semi-circular. The top heights of the first inner liner assembly 5 and the second inner liner assembly 6 are at the same horizontal height. At the same time, the metal parts of the first inner liner assembly 5 and the second inner liner assembly 6 move relative to each other along the top of the processing table 1 through the first reverse lead screw 3 and the second reverse lead screw 4, respectively.
[0026] In this embodiment, as Figure 4 As shown, both the top welding assembly 12 and the edge welding assembly 13 are composed of an electrode chuck and a metal welding head. The welding head is strip-shaped and connected to the electrode chuck by bolts. The welding heads of both the top welding assembly 12 and the edge welding assembly 13 are distributed in an inclined manner.
[0027] In this embodiment, as Figure 4 As shown, the column 2 is fixedly connected to the corresponding ends of the first push cylinder 10 and the second push cylinder 11 at the installation positions of the two ends. The output ends of the gas spring hydraulic support rods 14 are fixedly connected to the electrode clamps of the top welding assembly 12 and the edge welding assembly 13 on the corresponding sides, respectively. The top welding assembly 12 and the edge welding assembly 13 are vertically distributed, and the top welding assembly 12 is located above the processing table 1 and the edge welding assembly 13.
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the working process of this fan cover processing equipment is as follows:
[0029] First, the operator arranges the fan cover and the coiled components to be welded to it. These are then clamped and secured using the first inner lining assembly 5 and the second inner lining assembly 6. The semi-circular ends of the first and second inner lining assemblies 5 and 6 can be aligned with the circular edge of the fan cover, better adapting to its shape and providing stable support and reliable clamping. The spacing between the first and second inner lining assemblies 5 and 6 is adjusted via the first reverse screw 3 and the second reverse screw 4 to accommodate different sizes of fan covers, enhancing the equipment's versatility. The first and second reverse screws 3 and 4 are arranged in a cross shape with intervals in the horizontal plane, allowing for more flexible adjustment of the two inner lining assemblies in different directions. After precisely positioning and supporting the fan cover, and fixing it in place, the position of the column 2 is adjusted using the horizontal screw 9 according to the size and specifications of the workpiece and the welding location. This ensures that the top welding assembly 12 and the edge welding assembly 13 are better aligned with the welding points. During welding, the power output end of the first push cylinder 10 moves the top welding assembly 12 vertically to weld the fan cover to the top component. The power output end of the second push cylinder 11 moves the edge welding assembly 13 horizontally to weld the fan cover to the corner of the component. The column 2 is fixedly connected to the corresponding ends of the first and second push cylinders 10 and 11 using a pneumatic spring hydraulic system. Support rod 14 provides stability in the running direction for the top welding assembly 12 and the edge welding assembly 13, ensuring the stability of the welding process. The welding heads of both the top welding assembly 12 and the edge welding assembly 13 are inclined. Since most fan covers are welded to curved metal columns, there will be a certain degree of curvature at the top or edge. Inclined welding heads, compared to ordinary vertical or horizontal welding heads, achieve a closer fit with the curved surface. This allows heat to be evenly transferred to the welding area during the welding process, avoiding welding defects such as porosity and cracks caused by localized overheating or undercooling. This significantly improves the quality and strength of the weld, ensuring the stability and reliability of the connection between the fan cover and the curved metal column. Both the top welding assembly 12 and the edge welding assembly 13 are equipped with electrode clamps and... The welding head is made of metal. During welding, the electrode chuck is connected to the welding power source, and the current is conducted to the metal welding head through the electrode chuck. The welding head can be changed according to the specifications of the workpiece. After welding at each position is completed, the top welding assembly 12 and the edge welding assembly 13 reset. At this time, the drive gear 7 rotates via a stepper motor and meshes with the driven gear 8. Since the shaft at the center of the driven gear 8 is fixedly connected to the center of the bottom of the processing table 1, the processing table 1 rotates horizontally below the top welding assembly 12 and the edge welding assembly 13 around the axis of the driven gear 8 through the meshing transmission of the drive gear 7 and the driven gear 8. The first inner liner assembly 5 and the second inner liner assembly 6 on the surface of the processing table 1 drive the workpiece to rotate horizontally.The rotating structure allows for continuous welding by rotating another untouched area to the welding angle, facilitating the welding process again. This improves welding efficiency while ensuring the accuracy and consistency of the welding position.
