When adopting technique scheme, will by before annulus to be welded and blade clamping, unscrew the nut of clamping screw, outer plate, clip plate are all taken off, annulus is placed on base upper surface, then blade is inserted in the blade profile hole of annulus, tumbler ring, the tip making the locating hole on annulus and backstay locate side aligns, rotational positioning bar, because backstay outer surface is provided with thread groove, and holding screw inserts in thread groove, so backstay moves along its axis and inserts in the locating hole on annulus, now locate complete.Then clip plate, stage clip and outer plate are loaded, and fastening nut, now blade clamps by clip plate, and annulus clamps by outer plate.Now, annulus to be welded and blade are all clamped and location, can weld.In the present invention, be provided with thread groove at the outer surface of backstay, and on guide holder, be provided with the holding screw inserting thread groove, in the process of rotational positioning bar, backstay just can be regulated along the movement of self axis, annulus is located.And existing this kind of clamping device is connected with backstay threaded one end by screw, in use easily loosen, the present invention can address this problem well.
Further, described backstay is provided with and thread groove continuous print straight trough near Workpiece fixing side, being provided with straight trough can along the position of the axial running fix bar rapidly of backstay.
Further, the outer rim of described clip plate clamping blade is provided with rubber blanket, and the thickness of blade is less, and the end face of clamping blade easily causes deformable blade, and the outer rim of clip plate clamping blade is provided with the distortion that rubber blanket can reduce blade.。
Further, described base is provided with the lead running through clip plate and outer plate, lead and clamping screw run through clip plate, outer plate respectively, so can prevent clip plate or outer plate in use procedure from rotating, tightening and unscrewing in nut process to prevent clip plate and outer plate from rotating, convenient operation.
Further, described backstay is provided with handler away from one end, location, directly just can be tightened by handler or unscrew backstay, so convenient, laborsaving in use procedure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of weld clamp device embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of weld clamp device, comprise base 1, clamping section and location division, clamping section comprises outer plate 2, clip plate 3 and clamping screw 4, and wherein, outer plate 2, clip plate about 3 are arranged, clamping screw 4 runs through clip plate 3, outer plate 2, and lower end is connected with base 1, upper end compresses outer plate 2 by nut 6, and the clamping screw 4 between clip plate 3, outer plate 2 is arranged with stage clip 5; Location division comprises guide holder 8, holding screw 9 and backstay 7, annulus 11 one end located by backstay 7 is taper, and backstay 7 outer surface is provided with thread groove 71, guide holder 8 is fixed on the base 1 of outer plate 2 side, and guide holder 8 offers the through hole be slidably matched with backstay 7, holding screw 9 is fixed on guide holder 8, and one end is inserted thread groove 71 and coordinated with it.
