Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

In this embodiment, referring to fig. 1-4, a single-side welding and fixing device for a large-diameter thick-wall smelting furnace comprises a fixing table 1 and an extension table 2 circumferentially arranged outside the fixing table 1, wherein sliding plates 7 are respectively and slidably connected to the extension table 2, the sliding plates 7 are radially arranged, a sliding groove 11 is formed in the central axis of the table surface of the extension table 2 along the length direction of the table surface, a sliding way which is identical to the sliding groove 11 is formed in the edge of the table surface of the fixing table 1, and the sliding plates 7 radially slide onto the table surface of the fixing table 1 from the table surface of the extension table 2 along the sliding groove 11, as shown in fig. 2 or fig. 3.

The face front side of sliding plate 7 is provided with fixed column 8, and the rear side is provided with mount pad 9, and revolving stage 3 is installed through rotation axis 10 rotation in the mesa center of fixed station 1, and the bottom of fixed station 1 is provided with installation base 5, and the inside of installation base 5 is provided with drive rotation axis 10 pivoted motor 6. The rotation of the rotary table 3 is controlled by a motor 6.

The table top of the rotary table 3 is provided with a plurality of arc grooves 13 distributed in the circumferential direction, the fixed column 8 at the front side of each sliding plate 7 is respectively arranged in a corresponding arc groove 13 and slides along the groove channel, and the mounting seat 9 is provided with a workpiece clamping groove 14 for inserting and placing the single plate 12. It should be noted that, the groove wall profile of the workpiece clamping groove 14 is an arc surface, and the arc surface is matched with the corresponding plate surface profile of the single plate 12, so that the purpose of the design is to ensure that the single plate 12 can be clamped in the workpiece clamping groove 14 with a high degree of adhesion, and provide sufficient stability.
