Abstract
The utility model provides a quick clamping device for elbow longitudinal seam welding, which is characterized in that the quick clamping device is provided with a bottom plate and a circumferential clamping flange; the bottom plate is provided with three clamp heads along the circumference; two clamp heads are fixedly arranged on the bottom plate, and the tail end of the third clamp head is connected with a screw rod; a support base is arranged on the bottom plate and is formed with a through screw hole towards the circle center of the circumference; the screw rod is screwed in the through screw hole; the lateral surfaces of the three clamp heads, which face towards the circle center of the circumference, are reverse and downward inclined surfaces, and the reverse inclined surfaces of the three clamp heads form a spatial taper surface; and the outer lateral surface of the clamping flange is an upward external taper surface of which the angle is matched with the angles of the reverse inclined surfaces of the three clamp heads. The quick clamping device has the beneficial effects that the cantilever type clamping elbow is adopted, so the structure is compact, the floor area is small and larger space is provided for the subsequent operation; as only one movable clamp head is adopted, the clamping is quick and the clamping force is large; the thread structure has self-locking property, so the operation is safe and reliable; as the clamping flange has a taper surface, the clamping flange can be tightly attached to the bottom plate of the fixture under the self gravity of the elbow after the clamping flange enters the fixture; and after the clamping head is moved, the workpiece cannot fall down even if the movable clamp head is not locked completely, so the safety is high.
Description
Technical field
The utility model relates to a kind of quick clamping device, particularly a kind of elbow longitudinal seam welding elbow quick clamping device.
Background technology
All adopt elbow middle part both sides welding circular shaft after-frame swing on the planer-type moulding bed for manual welding during existing elbow longitudinal seam welding, the moulding bed occupation of land is bigger, swings not steadily because of both sides are difficult for centering, can not adapt to automatic requirement of welding.
Summary of the invention
The utility model provides a kind of elbow longitudinal seam welding quick clamping device, and purpose is to solve the prior art problem, provides a kind of and can adapt to the elbow that the elbow longitudinal joint welds automatically.
The utility model technical scheme that adopts of dealing with problems is:
Elbow longitudinal seam welding quick clamping device, it is characterized in that: have base plate, base plate upper edge one circumference is provided with three chucks, wherein two chucks are fixedly arranged on base plate, the tail end of another chuck is connected with a screw rod, base plate is provided with bearing, offer logical screw on the bearing towards the center of circle of above-mentioned circumference, above-mentioned screw rod spiral shell is located in the above-mentioned logical screw, above-mentioned three chucks are the reverse slope towards the below towards the side in the center of circle of above-mentioned circumference, and the reverse slope of above-mentioned three chucks can constitute the conical surface on the space; Also has circle-shaped clamping flange, the lateral surface of clamping flange the male cone (strobilus masculinus) that to be angle cooperate with reverse slope on above-mentioned three chucks towards the top.
The beneficial effects of the utility model: the elbow quick clamping device adopts cantilevered clamping elbow, compact conformation, and floor space is few, for subsequent operation provides bigger space; Because only adopt a mobile chuck, so clamping is rapid, and folder power is big, helicitic texture has self-locking performance, and is safe and reliable.The clamping flange has the conical surface, as long as enter in the anchor clamps, just can be close to the anchor clamps base plate under the elbow deadweight, even the not locking fully of mobile chuck, workpiece can not fall down yet, and is safe.

The specific embodiment
As shown in Figure 1, the utlity model has base plate 1, base plate 1 upper edge one circumference is provided with some screws as fixing hole 10, have three chucks 21,22,23, two chucks 21 wherein, 22 is fixed chuck, cooperation by screw rod 20 and fixing hole 10 is fixedly arranged on base plate 1, another chuck 23 is an active chuck, the tail end of active chuck 23 is connected with a screw rod 24, base plate 1 is provided with bearing 25, offer the logical screw towards the center of circle of above-mentioned circumference on the bearing 25, above-mentioned screw rod 24 spiral shells are located in the above-mentioned logical screw, also are that rotating screw bolt 24 just can push-and-pull active chuck 23.Active chuck 23 is clamped in two fixed blocks 29 that are fixed on the base plate 1 to keep the direction of motion.The reverse slope that above-mentioned three chucks 21,22,23 also promptly are towards the below towards interior medial surface 210,220,230 towards the side in the center of circle of above-mentioned circumference, three reverse slopes spatially form a conical surface.
As shown in Figure 2, the utility model also has circular clamping flange 3, the lateral surface of clamping flange 3 male cone (strobilus masculinus) 31 towards the top that to be angles cooperate with reverse slope formula medial surface 210,220,230 on above-mentioned three chucks also is that clamping flange 3 can firmly be clamped by three chucks 21,22,23 with cooperating of medial surface 210,220,230 by male cone (strobilus masculinus) 31.
The base plate 1 of elbow quick clamping device is installed on the positioner (not shown) during use, and large-scale elbow 4 usefulness connecting plates spot weld on the clamping flange 3.Connecting plate can be an annular, and as shown in Figure 3, Figure 4,4 at elbow is welded on the annular connecting plate 5, and connecting plate 5 is welded on the clamping flange 3 again.Connecting plate also can be a square plate, and as Fig. 5, shown in Figure 6,4 at elbow is welded on the square connecting plate 6, and connecting plate 6 is welded on the clamping flange 3 again.
Elder generation's rotary screw 24 falls back on the outside to the active chuck 23 of slide block type, with driving clamping flange 3 is hung between three chucks 21,22,23 then.Rotary screw 24 holds out against clamping flange 3 to active chuck 23 again, promptly finishes an elbow 4 cantilevereds and is sandwiched on the positioner.
