The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1 and Figure 2, curve housing weld groove processing tool, comprise base, base is comprised of cylindrical shell 1 and the circular bottom plate 2 that is arranged on cylindrical shell 1 lower end, offer on the cylindrical shell 1 for human body and enter manhole 3 in the cylindrical shell 1, along being provided with at least two arc plates 4 on the cylindrical shell circumferencial direction, link to each other by location-plate 26 between the adjacent arc plate 4 on cylindrical shell 1 inwall.Adopt four arc plates in this implementation column.The arc-shaped side 5 of arc plate 4 forms a cambered surface suitable with curve housing outer arcuate face.Contact with the outer arcuate face of curve housing 6 but do not affect its location in order to be beneficial to arc-shaped side 5, arc-shaped side 5 middle parts can be arranged sunk area, arc-shaped side 5 that namely should the zone does not contact with the extrados of curve housing 6.Be provided with at least two bases 7 that curve housing 6 is withstood on the base plate 2, also be provided with at least three root posts 8 on the base plate 2, adopt four root posts 8 in the present embodiment.Be fixed with the locating ring 9 of annular on the column 8 by screw bolt and nut, cylindrical shell 1 upper end is provided with the flat board 10 of annular, be provided with the gap 11 for curve housing 6 location on dull and stereotyped 10 inner side edges, be provided with at least two on the locating ring 9 towards the upper holding device 12 of gap 11, be provided with the lower holding device 13 of regulating curve housing 6 positions on the base plate 2.
Adopt following lower holding device simple in structure, upper holding device and base in the present embodiment.As shown in Figure 4, described lower holding device 13 comprises lower locating piece 14, minor axis 15 and the ∏ shape pushing block 16 that is arranged on the base 2, be connected with bearing pin 17 between two vertical sections of pushing block 16, the two ends of minor axis 15 are respectively arranged with mutually reverse screw thread, one end of minor axis 15 is threaded with lower locating piece 14, and the other end is threaded with bearing pin 17.Because curve housing 6 is larger, be provided with two through holes 18 radially at the middle part of minor axis 15, and the center line of two through hole 18 is mutually vertical, rotating 15 o'clock, can utilizes lever to stretch in the through hole 18, thereby can utilize less power to rotate minor axis 15.When rotating minor axis 15, because it is mutual reverse screw thread that the two ends of minor axis 15 are arranged on, so pushing block 16 and lower locating piece 14 will be mutually near or away from, again since lower locating piece 14 be fixed on the base plate 2, thereby can realize purpose that curve housing 6 is advanced or retracts.Because be provided with bearing pin 17 on the pushing block 16, this is convenient to pushing block 16 and is adjustable to suitable position when propping up curve housing 6, and do not affect the function of lower holding device 13 just so that between pushing block 16 and the minor axis 15 small change in displacement can be arranged.As shown in Figure 5, described upper holding device 12 comprises the upper locating piece 19 on the fixing locating ring 9 and the screw 20 that is threaded with upper locating piece 19.As shown in Figure 3, described base 7 comprises transverse slat 21, riser 22 and swash plate 23, two mounting holes 24 are set on the transverse slat 21, riser 22 is vertically welded on the transverse slat 21, swash plate 23 is vertically welded on the transverse slat 21 and meet to the bottom of curve housing 6 on a plane of swash plate 23, and base 7 is by passing being bolted on the base plate 2 of mounting hole 24 on the transverse slat 21.
Operation principle of the present utility model is: curve housing 6 is placed on the arc-shaped side 5 of arc plate 4, pushing block 16 end faces in the lower end of curve housing 6 and the lower holding device 13 offset, then be shelved on locating ring 9 on the column 8 and utilize bolt, nut to fix, need on the curve housing 6 this moment to stretch out the gap 11 of end on dull and stereotyped 10 of finished edge, then rotate minor axis 15 and regulate end, curve housing 6 upper end to correct position, i.e. the punching of sample on the curve housing 6 point is to correct position.Movable base 7 again, so that the limit, lower end of the inclined-plane of swash plate 23 and curve housing 6 offsets, then clamping screw is fixed on base 7 on the base plate 2, and rotary screw 20, the upper end of curve housing 6 are fixed in dull and stereotyped 10 the gap 11.After curve housing 6 is fixed, just can carry out machined to limit, curve housing 6 upper end, owing to having adopted machined, just can process U-shaped groove 25, also can process double V groove simultaneously---shown in Figure 6.The advantage of U-shaped groove is: weld size is little, and not only welding job amount is little, and welding deformation is also little.Welding material consumption, to boost productivity and to reduce cost.Thereby can improve the quality of weld seam in end socket or the storage tank, improve its life-span.After adopting machined, can also guarantee the requirement of groove face roughness≤12.5mm, guarantee the requirement of groove face flatness≤1mm, guarantee the requirement of Spherical Tank Shell Plates counterpart unfitness of butt joint≤2mm, guarantee the dimension precision requirement of groove, satisfy the requirement that surface infiltration (PT) detects.
