When the round tube column 612 completes the central axis positioning, the grabbing and conveying of the reinforcing rib plate 62 and the abutting and tightening operation between the round tube column 612 can be completed through the grabbing and abutting mechanism 5, specifically, the grabbing and executing assembly 55 is driven by the traversing assembly 51 to move to the position right above one reinforcing rib plate 62 conveyed by the rib plate conveyor 2, then the grabbing and executing assembly 55 is driven by the starting lifting cylinder 52 to move downwards, the reinforcing rib plate 62 is relatively moved between the two side clamping pieces 552, then the driving cylinder 551 is started to pull the two side clamping pieces 552 to move towards each other through the two pulling connecting rods 553, then the reinforcing rib plate 62 is clamped between the two side clamping pieces 552, then the lifting cylinder 52 is started again to drive the reinforcing rib plate 62 to be separated from the limiting groove 21 to complete the clamping and lifting, then the clamped reinforcing rib plate 62 is driven by the traversing assembly 51 to move to the round tube column main body 61 for completing the central axis positioning, so that the vertical edge of the reinforcing rib plate 62 contacts with the outer wall of the round tube column 612, then, the lifting cylinder 52 is started again to drive the reinforcing rib plate 62 to move downwards and contact with the end face of the fixed chassis 611, as the clamping balls 5523 which are in clamping contact with the surface of the reinforcing rib plate 62 can roll along the surface of the surface, the two side clamping pieces 552 move downwards along the surface of the two sides of the reinforcing rib plate 62, simultaneously the bearing frame 54, the grabbing execution assembly 55 and the leaning assembly 56 move downwards synchronously, the inclined surface of the leaning clamping block 561 contacts with the inclined edge of the reinforcing rib plate 62, then moves downwards continuously, the leaning clamping block 561 applies an inclined side clamping force to the reinforcing rib plate 62, the vertical component force thereof compresses the vertical compression spring 5412 to generate vertical pressure, the horizontal component force thereof forces the side clamping spring 563 to compress and generate lateral horizontal clamping force, then, in the precondition that the two side clips 552 keep the reinforcing rib plate 62 aligned, the welding contact position between the reinforcing rib plate 62 and the round tube column 612 and the fixing base plate 611 is further kept clamped, so that the welding strength and reliability of the welding contact position after welding forming can be improved. It should be noted that, the surface of the clamping ball 5523 is roughened, and the clamping ball 5523 is embedded in the base block 5521 to have a large rolling resistance, when the reinforcing rib 62 with a certain weight is clamped, the rolling resistance of the clamping ball 5523 can overcome the dead weight of the reinforcing rib 62 and realize clamping, and when the pressing cylinder 41 is started to drive the two side clamping pieces 552 to move downward, the pressing thrust can overcome the rolling resistance of the clamping ball 5523 so that the clamping ball 5523 can roll along the plate surface of the reinforcing rib 62.
When the butt joint of the reinforcing rib plate 62 is tightly attached through the grabbing butt joint mechanism 5, automatic welding can be completed through the welding mechanical arm, after welding is completed, the grabbing butt joint mechanism 5 is loosened and moved to the initial position, the rotary part 44 rotates the round tube stand column main body 61 by a fixed angle to enable the round tube stand column main body 61 to rotate to the next butt joint welding position, as shown in fig. 11, the reinforcing rib plate 62 which is uniformly distributed is contained in the reinforcing round tube stand column 6, therefore, the intermittent stirring angle of the rotary part 44 is 60 degrees, after stirring is completed, the reinforcing rib plate 62 is grabbed and butted again through the grabbing butt joint mechanism 5, and then welding forming of the single reinforcing round tube stand column 6 can be completed through six continuous operations.
In summary, the gantry machining center device provided by the invention can be used with a welding mechanical arm, and can replace manual work to complete automatic welding operation on the reinforced circular tube column 6, the circular tube column main body 61 and the reinforced rib plate 62 to be welded can be respectively and intermittently aligned and conveyed through the arranged column main body conveyor 1 and the rib plate conveyor 2, the circular tube column 612 can be automatically positioned by the arranged positioning shifting mechanism 4, and the welding shifting position is performed, and the butt joint conveying and the welding clamping operation between the reinforced rib plate 62 and the circular tube column main body 61 can be automatically completed through the arranged grabbing and butt joint mechanism 5, so that the problems of labor-consuming manual operation error and unreliable manual welding clamping in the manual welding process are solved, the welding machining efficiency is greatly improved, and the stability and reliability of the welding quality of the reinforced circular tube column 6 are improved.
