Description

Technical Field

[0001] The utility model relates to a welding integrated device, in particular to an integrated device for furnace roll welding. Background Art

[0002] The welding of the weld seam after the assembly of the conveying roller components of the glass annealing furnace is a key link in product manufacturing. At present, the circumferential welds at both ends of the conveying rollers of the glass annealing furnace are usually welded manually. Its disadvantages are low work efficiency and unstable weld quality. In mass production, these problems have a great impact on ensuring quality and meeting the delivery date. Therefore, the traditional manual welding process cannot meet the requirements of industrial mass production in terms of operation efficiency and weld quality. One of the main factors leading to low work efficiency is that since the length and weight of the assembled glass annealing furnace conveying roller components as workpieces are relatively large, it is time-consuming and laborious to align and adjust them with the rotary drive mechanism.

[0003] On the other hand, the dust collection box used in conjunction with the welding operation is generally arranged at a fixed position near the workpiece. A relatively long air duct needs to be connected to connect the dust collection hood and the box body. And when changing the welding position of the circumferential welds at both ends of the glass annealing furnace conveying roller, it is necessary to correspondingly change the layout of the air duct, or two sets of air ducts and dust collection hoods need to be configured. This is not only cumbersome in operation, but also occupies a large amount of workshop space. Summary of the Utility Model

[0007] Preferably, the welding torch support mechanism includes a second vertical shaft fixed to the bottom end of the frame body. A first cross bar is rotatably and slidably connected to the second vertical shaft. A first vertical shaft is horizontally slidably connected to the first cross bar. A welding torch clamping mechanism is rotatably and slidably connected to the first vertical shaft.

[0008] More preferably, the welding torch clamping mechanism includes two clamping blocks for clamping the welding torch. The two clamping blocks are connected to each other by a connecting bolt.

The upper end of the lead screw 15-4 is connected to a supporting wheel frame 2, and the left and right sides of the supporting wheel frame 2 are respectively installed with supporting wheels 17 for supporting the workpiece 13. When the workpiece 13 is placed on the supporting wheels 17 on the left and right sides, the central axis of the workpiece 13 is in the left and right directions ( Figure 3 Left and right directions shown, Figure 1 The chuck is aligned with the center of the chuck 4 in the front-to-back direction (as shown).

[0025] To support workpieces 13 with different pipe diameters and align the central axis of the workpiece 13 with the center of the chuck 4 in the height direction, the supporting wheel frame 2 of the supporting trolley 15 in this embodiment can move up and down. Specifically, by rotating the handle 15-6 to drive the lead nut 15-5 to rotate self, the lead screw 15-4 cooperating with the lead nut 15-5 drives the supporting wheel frame 2 to move up and down, achieving the purpose of adjusting the height of the workpiece 13.

[0026] Still as Figure 1 and Figure 2 , this embodiment further includes a secondary track 12 provided on one side of the main track 1 and parallel to the direction of the main track 1. An auxiliary trolley is provided on the secondary track 12. The auxiliary trolley includes a frame body. Wheels running on the secondary track 12 are installed on the lower side of the frame body. A welding machine 9 and a dust collecting box 11 are installed side by side on the frame body. A dust removal filter is provided in the dust collecting box 11. The dust removal filter is connected with an air draft pipe 10. The outer end of the air draft pipe 10 is connected with a dust collecting hood 16. During use, the dust collecting hood 16 faces the welding part.

[0027] The welding machine 9 is connected with Figure 4 the welding torch support mechanism shown in Figure 5 .

[0031] Use a crane to lift the workpiece 13 above the main track 1, and slowly lower it until the center height of the workpiece 13 is equal to that of the chuck 4. Insert the shaft end of the workpiece into the chuck 4. After adjusting the orientation of the workpiece to be horizontal, slowly tighten the chuck 4. Move the support trolley 15 to a suitable position on the roll body of the workpiece 13, and adjust the height of the idler support 2 through the lead screw and nut mechanism so that the idler 17 fully supports the furnace roll and ensures close contact between the roll body of the furnace roll and the idler set. Slowly release the lifting tooling of the crane. After checking the chuck 4 again, start the motor 7 and set the rotation speed so that the rotation speed of the furnace roll (workpiece 13) matches the welding speed.

[0032] Move the auxiliary trolley on the auxiliary track 12 to the welding station. Turn on the welding machine 9, and move the welding torch 24 to the welding position by adjusting the welding torch support mechanism and the welding torch clamping mechanism. Ignite the arc to start welding. After the 360° welding of this weld seam is completed, move the auxiliary trolley to move the welding machine 9 and the dust collector 11 to other weld seam positions to complete the welding of other weld seams. After all the weld seams are welded, turn off the welding machine 9, the dust collector 11 and the motor 7. Use a crane sling to lift the furnace roll, loosen the chuck 4, and lift the furnace roll to the storage position.

[0033] The power system of the embodiment of the present invention is that the motor 7 drives the speed reducer 5, and the output shaft of the speed reducer 5 drives the chuck 4 to rotate. The motor 7 is a frequency conversion motor, and the rotation speed is adjusted through a frequency converter.
