The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
A kind of robot welding anchor clamps, as shown in Figure 1, comprise the left and right terminal pad 2 that is arranged symmetrically in workpiece 3 both sides, 20, be located at left and right terminal pad 2, support slide rail 1 between 20, this support slide rail 1 middle position is equipped with second hold down gag 5 of workpiece pressing 3 lower covers, at second hold down gag 5 and left and right terminal pad 2, between 20, with second hold down gag 5 is that the center symmetric arrangement has positioner 6 and first hold down gag 4 that is used for workpiece pressing 3 ends, and the positioner 6 and first hold down gag 4 are fixed on and support on the slide rail.Described first hold down gag 4, second hold down gag 5, positioner 6 can be finely tuned by movable bolt 15 scenes according to the size of workpiece 3 at the particular location that supports on the slide rail 1.
Shown in Fig. 1～4, described first hold down gag 4 comprises base plate 7, is contained in the gusset 8 on the base plate 7, is contained in the cover plate 9 that is used for supporting workpiece 3 on the gusset 8, be located at the block 10 of cover plate 9 one sides, and be bolted in the briquetting 11 that is used for workpiece pressing 3 two ends on the cover plate 9 workpiece 3 fore-and-aft directions location.The screwed hole 16 that the M24 that processes is arranged on the cover plate 9 has the bolt 17 of M24 on the briquetting 11, after whole work-piece 3 all directions were all had good positioning, briquetting 11 was by bolt workpiece pressing 3 ends.It should be noted that briquetting 11 positions are unsuitable too high, in order to avoid bump rifle.
Shown in Fig. 5～6, described second hold down gag 5 comprises the base plate 70 that is used for supporting workpiece 3, is fixed on the square spiral shell seat 12 on the base plate 70.During work, the M16 bolt that is equipped with on the square spiral shell seat 12 is used for the location of workpiece 3 fore-and-aft directions.
Shown in Fig. 7～9, described positioner 6 comprises base plate 71, is contained in the side plate 13 on base plate 71 both sides, is contained on the base plate 71 and is used to block the location-plate 14 of workpiece 3 between biside plate 13.During the location, location-plate 14 blocks workpiece 3 draw-bar seat home records, positioner 6 can be up and down and the position of left and right directions adjusted workpiece 3, after frock is debugged for the first time, movable bolt 15 usefulness nut checks are maintained static, can to about the workpiece 3, left and right directions positions, and can also assist the fore-and-aft direction location.
Described support slide rail 1 is that one 250mm * 10mm * 4500mm seamless cold square steel tube and low alloy steel plate assembly welding integral body process parts, the versatility of anchor clamps be can guarantee, shear stress and tension that enough intensity is produced in the time of bearing workpiece 3 rotations guaranteed simultaneously.
During installation, at first by the robot welding anchor clamps are passed through left and right terminal pad 2,20 are contained on the left and right robot welding positioner, then workpiece 3 is lifted on the robot welding anchor clamps, utilize 6 pairs of workpiece of positioner 3 to carry out level and vertical direction location, by the lower cover of second hold down gag, 5 workpiece pressings 3, clamping is realized at briquetting 11 workpiece pressings 3 two ends of first hold down gag, 4 tops at last.
These robot welding anchor clamps, having overcome common anchor clamps centre does not have clamping and positioning, and the workpiece positioning accuracy is low, the shortcoming that post welding distortion is bigger, whole anchor clamps have been made an integral body, and the centre increases positioner and hold down gag, has improved the positioning accuracy of whole weld jig greatly.Can not only guarantee that robot successfully welds workpiece, and control welding deformation well, simultaneously, after anchor clamps are debugged for the first time, just some bolts can be fixed with nut check, guarantee the precision of workpiece repeated clamping.
