Embodiment
Fig. 1 is the concept map of expression according to the structure of the support skeleton body 2 02 of embodiment of the present invention 1.Support skeleton body 202 is the same with support skeleton body 201, the horizontal supporting with along continuous straight runs H supporting aperture grill to 12 and supports horizontal support to 12 vertical support to 11.Horizontal supporting to 12 each all have water supporting mass 12a, the 12b that along continuous straight runs H extends, vertical support to 11 each all have vertical support body 11a, the 11b that vertically extends.For example, vertical support is welded to each other 12 with horizontal supporting 11.
But, in the present embodiment, compared with prior art, the structure difference of horizontal supporting body 12a, 12b and vertical support body 11a, 11b.Horizontal supporting body 12a has face 12ar, the 12at perpendicular to direct of travel Z, perpendicular to the face 12as of vertical direction V, and face 12an parallel with horizontal direction H, that all tilt with respect to vertical direction V and direct of travel Z.Simultaneously, face 12ar, 12as, 12at, 12an connect successively, for example can form horizontal supporting body 12a by metallic plate of bending machining.Horizontal supporting body 12b has face 12br, the 12bt perpendicular to direct of travel Z, perpendicular to the face 12bs of vertical direction V, and face 12bn parallel with horizontal direction H, that all tilt with respect to vertical direction V and direct of travel Z.Simultaneously, face 12br, 12bs, 12bt, 12bn connect successively, for example can form horizontal supporting body 12b by metallic plate of bending machining.The angle of the angle of face 12an, 12at and face 12bn, 12bt is faced mutually.
Fig. 2 is the vertical view that follows when into direction Z observes support skeleton body 202.Horizontal supporting to 12 face 12at, 12bt with respect to the end of horizontal direction H all and vertical support to 11 face 11ar, 11br end welding with respect to vertical direction V, support skeleton body 202 is done as a whole, is " mouth " font on the face perpendicular to direct of travel Z.
Because horizontal supporting body 12a, 12b form by the bending metallic plate as mentioned above, so, even with this metallic plate attenuate and lightweight, also can guarantee to support face 12ar, the 12br of aperture grill, and suppress the reduction of rigidity.Particularly, face 12as, 12bs are last to be supported by being welded on respectively with respect to the opposition side end of face 12at, 12bt for face 112an, 12bn, can suppress the reduction of the rigidity of horizontal supporting body 12a, 12b.
Because vertical support body 11a, 11b are also as mentioned above, form by the bending metallic plate, so even described metallic plate of attenuate and lightweight, also can obtaining vertically, V stretches the required necessary rigidity of tension aperture grill.Thereby, eliminated the problem that causes support skeleton body 202 fixing aperture grills to be out of shape.For example, can with the thickness setting of this metallic plate 1.5～2.0mm.
On face 11at, the 11bt of vertical support body 11a, 11b, offer location hole 11p, 11q respectively.Location hole 11p, 11q are used for the location of relevant horizontal direction H and vertical direction V, are configured in the substantial middle of vertical maintenance body 11a, 11b, on the imaginary line PQ of along continuous straight runs H.
Fig. 3 is the enlarged drawing of details of a part of III of presentation graphs 2.The profile of location hole 11p has arc sections 11pa, 11pc, with the line part 11pb of the along continuous straight runs H extension that is connected arc sections 11pa, 11pc.Arc sections 11pa is connected with line part 11pb at the opposition side of vertical support body 11b.The center of circle that arc sections 11pa, 11pc become a part is configured on the imaginary line PQ basically, thereby line part 11pb is on imaginary line PQ, dispose abreast with horizontal direction H.Location hole 11q forms identical shape with location hole 11p.
The concept map of Fig. 4, Fig. 5 method that to be expression position with respect to the relevant horizontal direction H of support skeleton body 2 02 and vertical direction V.With reference to Fig. 4, for support skeleton body 202, alignment pin 34,36 follows into direction Z (being the top here) and advances, and is fitted to respectively in location hole 11p, the 11q.The line RS that connects alignment pin 34,36 is arranged essentially parallel to horizontal direction H.Contact with face 11at, 11bt respectively by being configured in respect to alignment pin 34,36 with the rightabout supporter 35,37 of direct of travel Z, alignment pin 34,36 follows into that advancing of direction Z once stopped.
In Fig. 3, the position 34 ' of expression alignment pin 34 when chimeric, alignment pin 34 with respect to location hole 11p.Because the profile of location hole 11p has line part 11pb, there is clearance the position of the alignment pin 34 of H in the horizontal direction, so, can be easy to alignment pin 34 chimeric with respect to location hole 11p.In addition, bigger by the diameter that makes arc sections 11pa, 11pc than the diameter of alignment pin 34, on the position of alignment pin 34 relative vertical direction V, obtain clearance.
With reference to Fig. 5,,, it is left mutually being parallel on the horizontal direction H to alignment pin 34,36 application of forces 104 at each alignment pin 34,36 relative positioning hole 11p, the chimeric state of 11q.Because the profile of location hole 11p has line part 11pb, so alignment pin 34 moves to horizontal direction H, arrives the position that is inscribed within arc sections 11pa 34 shown in Figure 3 ".Similarly, do not illustrate among the figure, alignment pin 36 is inscribed among the location hole 11q on vertical body 11a arc sections at a distance.Whereby, can stablize and carry out accurately reliably location on the H and vertical direction V in the horizontal direction.
In addition, compare with the prior art of utilizing locator 31 (Figure 16) and two mechanisms of locator 32 (Figure 17) to carry out the location of horizontal direction H and vertical direction V, in the method for present embodiment, can carry out the location of horizontal direction H and vertical direction V with a mechanism, have advantage stable, easy adjustment.
After the location of carrying out horizontal direction H and vertical direction V, alignment pin 34,36 follows into that advancing of direction Z begins once more.
Fig. 6 is the concept map of the method that positions on direct of travel Z with respect to support skeleton body 202 of expression.Supporter 35,37 (device 39 that is positioned in Fig. 6 covers) pushes away face 11at, 11bt on direct of travel Z, direction Z moves to make support skeleton body 202 follow into, contacts with tabular locator 39 up to face 11ar, the 11br of vertical support body 11.
Then, the same with prior art, one side pushes and makes horizontal supporting body 12a, 12b approaching mutually, and one side is seam welded to not shown aperture grill on face 12ar, the 12br.Owing to make the diameter of the diameter of arc sections 11pa, 11pb, has because of so that the mutual approaching pushing that mode applied of horizontal supporting body 12a, 12b the surplus of vertical support body 11a, 11b strain greater than alignment pin 34.Simultaneously,, depend on to horizontal supporting body 12a, 12b based on this strain vertical support body 11a, 11b by stopping to apply described pushing, to not shown aperture grill vertically V apply tension force, it is stretched tension.
When support skeleton body 202 being followed the location of direction Z into, what contact with alignment pin 39 is vertical support to 11 face 11ar, 11br, is not that horizontal supporting in prior art is to 12 face 112ar, 12br.Thereby, on horizontal supporting body 12a, 12b, seldom produce distortion, or the positional precision of support skeleton body 202 worsens.
In addition, even horizontal supporting deforms slightly to 12 since on shift onto and stitch weldering on the aperture grill, so, also can reduce this distortion.
In addition, the distance of location hole 11p, 11q is preferably big as much as possible, so that support skeleton body 202 is difficult to rotation when the power 104 of applying.
Obtain like this have support skeleton body 202 and an aperture grill select the look skeleton body as described in the present embodiment, the bending process by metallic plate constitutes horizontal supporting to 12, compares with the situation that adopts prior art to position, dimensional accuracy improves about 40%.
Execution mode 2
In order to follow the into location of direction Z, with vertical support 11 face 11ar, locator that 11br contacts being there is no need is to be tabular as locator 39.
Fig. 7 is that the support skeleton body 202 according to embodiment of the present invention 2 follows the into concept map of direction Z location.In the present embodiment, as shown in Figure 7, adopt locator 38a～38c.When following the location of direction Z into, locator 38a contacts with the face 11ar of vertical support body 11a, and when following the location of direction Z into, locator 38b, 38c contact with the face 11br of vertical support body 11b.Like this, as long as without detriment to following the horizontal direction H that carried out before the location of direction Z into and the location of vertical direction V, can make support skeleton body 202 to direct of travel Z move and vertical support contacts 11 face 11ar, 11br and stops, adopting other shape and structure also passable.
