Description
Technical Field
The invention belongs to an equidistant inner cavity structural member positioning device, in particular to an equidistant curved surface inner cavity structural member positioning device.
Background
In some special machines, an equidistant curved cavity structure is assembled, as shown in fig. 1 and 2, comprising a lower curved member 22, an upper curved member 23, a rear curved plate 24 and a front curved plate 25, respectively positioned in the lower, upper and rear, front, and two connecting flanges 21 connected to the lower curved member 22, the upper curved member 23, the rear curved plate 24 and the front curved plate 25 at the propyl ends thereof. As can be seen from fig. 1 and 2, the longitudinal section of the structural member of the cavity with the curved surface is a closed cavity with equal upper and lower distances and equal front and rear distances, and the curved shape, the transverse length and the longitudinal height of the lower curved surface piece 22, the upper curved surface piece 23, the rear curved surface piece 24 and the front curved surface piece 25 are the same. In general, when the space-between curved surface cavity structural members are assembled, lines are drawn at the space-between curved surface cavity structural members assembled by special machines, then the lower curved surface member 22 or the upper curved surface member 23 are assembled on the special machines respectively, then the rear curved surface plate 24 and the front curved surface plate 25 are connected with the lower curved surface member 22 or the upper curved surface member 23 respectively, and finally the two connecting flanges 21 are connected with the two ends of the lower curved surface member 22, the upper curved surface member 23, the rear curved surface plate 24 and the front curved surface plate 25 respectively. The technical problem with such an assembly is that whether the assembly is acceptable is determined by the accuracy and precision of the drawing, and the skill of the assembler, and the accuracy and precision are well guaranteed. If the accuracy and precision of the line drawing is poor, or the skill of the assembler is poor, the quality of the assembly is poor, or even unacceptable. Whether the assembly is qualified or not is usually detected by a sample with a longitudinal section equal to that of the equidistant curved surface inner cavity structural member and a length capable of ensuring that the whole of the sample passes through a bending position in the equidistant curved surface inner cavity structural member. During detection, the sample is placed into the equidistant curved surface inner cavity structural member from the upper end of the equidistant curved surface inner cavity structural member, and whether the equidistant curved surface inner cavity structural member is qualified is judged by observing whether the outer surface of the sample is identical to the inner wall of the inner cavity of the equidistant curved surface inner cavity structural member. The technical problems of such detection are; if the assembly of the equidistant curved surface inner cavity structural member is unqualified, particularly when the bending part is unqualified, a sample is blocked in the inner cavity of the equidistant curved surface inner cavity structural member, and the sample is very difficult to take out; when the position of the sample in the inner cavity of the equidistant curved surface inner cavity structural member is far away from the upper port or the lower port of the equidistant curved surface inner cavity structural member, whether the outer surface of the sample is identical to the inner wall of the inner cavity of the equidistant curved surface inner cavity structural member or not is difficult to clearly observe, whether the equidistant curved surface inner cavity structural member is qualified or not is difficult to judge, and errors are easy to occur. Meanwhile, whether the structural member is qualified or not is detected after the structural member is assembled, and if the structural member is detected to be unqualified, the structural member with the equidistant curved surface inner cavity is required to be disassembled for reassembly. This may cause the individual components of the equidistant from the curved surface cavity structure to be damaged, either entirely or individually, during disassembly, thereby resulting in an overall scrap.

Further, the three pairs of rotary connecting pieces are all pin columns with I-shaped two end parts larger than the middle part, and the rotary connecting holes are pin holes with the aperture slightly larger than the middle part of the pin column. This makes the structure of the three pairs of rotary joints relatively simple and relatively easy to manufacture.
