Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment jig frame special of the present utility model done and further elaborate, but protection domain of the present utility model can not be limited with this.
The utility model relates to the new exclusive frock of sectional construction in a kind of ship building, and this frock is custom-designed for marine stern axle tube sectional construction, so be named as " stern tube segmentation jig frame special ".The principle of design of this stern tube segmentation jig frame special is that stern tube section side state is built, and that is stern tube segmentation is built in vertical state.Therefore, the concrete size of jig frame special depends on the concrete size of the screw shaft pipe segmentation of construction.
In order to screw shaft pipe segmentation is convenient to build, the keystone configuration of this jig frame special is divided into inside and outside two parts: peripheral employing frame-type moulding bed, for ensureing size and the precision of subsection; The movable moulding bed that inner employing is made up of multiple active supporting member, this part contacts with the floor of segmentation, and segmentation major part weight is born by movable moulding bed.Jig frame special of the present utility model can repeated usage, to improve the operating environment of workman, also improves the construction precision of stern tube segmentation simultaneously.
As shown in Figure 1, this jig frame special includes peripheral frame-type moulding bed, inner movable moulding bed and ground moulding bed tap graticule to jig frame special arrangement states of the present utility model.
Above-mentioned frame-type moulding bed includes five split moulding beds, is respectively the second identical split moulding bed 2 of identical the first split moulding bed 1, two structures of two structures and a triad moulding bed 3.Five split moulding beds constitute peripheral frame, and peripheral moulding bed mainly contains two effects, and providing support to most bow end rib plate to install with outside plate provides benchmark.The requirement of peripheral moulding bed is consistent with the requirement of movable moulding bed, and the front view of external surrounding frame posture moulding bed as shown in Figure 4, Figure 5 and Figure 6.
Above-mentioned movable moulding bed includes multiple height-adjustable active supporting member, it is height-adjustable moulding bed conventional at present, inner use movable moulding bed, regulate very convenient, and ensure that gap, inner space is large, be convenient to workman enter into inside and carry out operation, the peripheral construction precision using frame-type moulding bed to be conducive to ensureing segmentation.
As shown in Figure 3, loose bed jig is that origin reference location is installed according to axial center to the layout of inner movable moulding bed.Have stern tube steel casting near axial center, heavier-weight, this region loose bed jig is arranged closeer.Moulding bed has following requirement: verticality of stand column permissible variation≤1/1000L; Moulding bed horizon permissible variation ± 2; Moulding bed column spacing permissible variation ± 3.Moulding bed height adopts (800+XXXX) form mark, and wherein 800 is moulding bed uniform level standard, and XXXX is the height that column should adjust apart from horizon.
Center line of shafting, end face theoretical projection line, plate suture and dimension line is included in above-mentioned moulding bed tap graticule.Moulding bed grid line chart is the important component part of moulding bed figure, is the line basis of moulding bed, as shown in Figure 2.The tap graticule of this figure is 1000*1000 specification, diagonal line permissible variation ± 1.5, limit deviation ± 3.This graph expression axial center, outer plate theory projection line and outside plate plate are sewn on the position on tap graticule.
Said frame formula moulding bed and movable moulding bed are all positioned in moulding bed tap graticule, and the first split moulding bed in frame-type moulding bed and the second split moulding bed are all that reference symmetry is placed with center line of shafting, triad moulding bed is positioned on center line of shafting, and it is that pedestal symmetry is placed that movable moulding bed is arranged in five split moulding beds and with center line of shafting.
Because jig frame special of the present utility model is implemented in full when 319K VLCC ship stern tube is built, and through repeatedly reusing, result of use is remarkable, reaches Expected Results during design, ensure that segmentation precision.
Facts have proved, the utilization of jig frame special in ship building of the utility model stern tube segmentation greatly reduces the vertical portion's labour power of group and labour intensity, enhances productivity, reduces sectional construction cost.
