The tooling plate 30 is positioned by the auxiliary half-width line 40 and the auxiliary height line 50 thereon, the auxiliary half-width line 40 is used for positioning the position of the tooling plate 30 in the width direction of the hull, and the auxiliary height line 50 is used for positioning the tooling plate. The position of the plate 30 in the height direction of the hull. In this embodiment, the thickness of the tooling plate 30 is 12-15 mm.
[0031] refer to figure 2 , the embodiment of the present invention ship segmental outer plate 10 and the positioning method of aggregate 20, comprising the following steps:
[0032] a. According to the shape of the outer plate 10 of the ship section and the coordinates of the relative hull in the length, width and height directions, the tooling plate 30 is designed. The tooling plate 30 has an outer edge 31 that fits with the inner surface of the outer plate 10, along the outer edge 31 is provided with a number of through holes 33 for aggregates 20 to pass through from top to bottom;
[0033] b. Cutting to obtain the tooling board 30, drawing a line on the tooling board 30, including several vertical auxiliary half-width lines 40 and several horizontal auxiliary height lines 50;
[0034] c. Assemble the tire frame base and longitudinal wall panels, the positioning base in the height direction of the hull is on the tire frame base surface, and the centerline of the hull is on the longitudinal wall panels;
[0035] d. Install the tooling plate 30, and take the tire frame base surface and the longitudinal wall plate as the reference, so that the horizontal distance between the auxiliary half-width line 40 and the longitudinal wall plate is the theoretical coordinate value k( Unit: mm), and the height distance between the auxiliary height line 50 and the tire frame base surface is the theoretical coordinate value h (unit: mm) of the auxiliary height line 50 relative to the hull base surface, the accuracy is controlled within 3mm, and the theoretical coordinate value k and h have been determined when making the tooling plate 30 in steps a and b;
[0036] e. Check the verticality of the tooling plate 30 relative to the base surface of the tire frame with a pendant hammer, and the verticality is controlled within 3mm;
[0037] f. Lift the aggregate 20 according to the through hole 33 on the tooling plate 30;
[0038] g. Hoist the outer panel 10 so that the inner surface of the outer panel 10 fits the outer edge 31 of the tooling panel 30;
[0039] h. Weld the outer plate 10 and the aggregate 20.
[0040] In the positioning method of the segmented outer plate 10 and the frame 20 of the ship, the tooling plate 30 has an outer edge 31 that fits the inner surface of the outer plate 10 and a through hole 33 for the frame 20 to pass through, so that the tooling plate 30 can be quickly installed The outer panel 10 and the frame 20 are positioned, while the tooling plate 30 is precisely positioned through the marking lines on it, including the auxiliary half-width line 40 and the auxiliary height line 50, which are respectively aligned with the tooling plate. 30 is positioned in the width direction and height direction of the hull. Therefore, the tooling plate 30 is first positioned and installed, and then the outer plate 10 and the frame 20 are positioned through the tooling plate 30, and finally the outer plate 10 and the frame 20 are welded. Compared with the direct measurement and positioning of the outer panel 10 and the frame 20, the measurement and positioning of the outer panel 10 and the frame 20 are transformed into the measurement and positioning of the tooling plate 30, which greatly reduces the positioning difficulty and improves the positioning accuracy, and can realize ship classification. The precise and rapid positioning of the outer plate 10 and the aggregate 20 improves the production efficiency, and the position of the outer plate 10 and the aggregate 20 is fixed by the tooling plate 30 , which can reduce the welding deformation of the outer plate 10 and the aggregate 20 .
[0041]In step d, the tooling plate 30 is installed in the length direction of the hull at the position of the section closing port of the ship, taking the front end or the rear end of the frame base as the reference, and retracting inward by a distance t (unit: mm), and the precision is controlled Within 3mm, here t is 50mm.
[0042] The outer edge 31 of the tooling plate 30 has higher precision requirements, and it fits the outer plate 10 of the ship section. It should be noted that the inner edge 32 of the tooling plate 30 is not required for positioning, so the line shape of the inner edge 32 can be adjusted according to the needs. It is not necessarily arc-shaped or curved, but can also be a straight line or an irregular shape. In this embodiment, in order to support the tooling and facilitate processing, the inner edge 32 of the tooling plate 30 is arc-shaped , in step d, the diagonal brace 80 is used to support and fix the tooling plate 30, and the diagonal brace 80 can use angle steel.
[0043] In this embodiment, there are two auxiliary half-width lines 40 and two auxiliary height lines 50. The greater the distance between the two auxiliary half-width lines 40, the higher the positioning accuracy. Preferably, the two auxiliary half-width lines 40 are respectively Set at the upper end and lower end of the tooling plate 30, the same is true for the two auxiliary height lines 50, the two auxiliary height lines 50 are respectively set at the upper end and lower end of the tooling plate 30, the auxiliary half-width line 40 and the auxiliary height line 50 cross each other vertical. Since the coordinate values k and h of the auxiliary half-width line 40 and the auxiliary height line 50 are large, up to 10m, if only one auxiliary half-width line 40 and auxiliary height line 50 are used, the positioning accuracy of the tooling plate 30 will be reduced. If three or more auxiliary half-width lines 40 and auxiliary height lines 50 are used, the positioning accuracy depends on the distance between the two furthest auxiliary half-width lines 40 and the farthest two auxiliary height lines. The distance between the lines 50 is equivalent to two auxiliary half-width lines 40 and two auxiliary height lines 50 . The theoretical coordinate values of the two auxiliary half-width lines 40 relative to the centerline of the hull are respectively k 1 and k 2 , the theoretical coordinates of the two auxiliary height lines 50 relative to the base surface of the hull are h 1 and h 2.
[0044] In some embodiments, the scribing in step b also includes an inspection line 60 , and in step d, before installing the tooling plate 30 , check whether the inspection line 60 is a straight line. The inspection line 60 is used to detect whether the tooling plate 30 is deformed after the fabrication of the tooling plate 30 and before installation. Since the accuracy of the tooling plate 30 determines the installation accuracy of the outer plate 10 and the frame 20, its precision requirements are relatively high. Deformation, it is necessary to check whether the inspection line 60 is still a straight line, and ensure that the straightness of the inspection line 60 is less than or equal to 1mm. If the straightness of the inspection line 60 is greater than 1mm, the tooling plate 30 has a certain deformation and cannot be used to position the outer plate 10 and Aggregate 20.
[0045] According to the shape of the outer edge 31 of the tooling plate 30, several (one or more) inspection lines 60 are set, and several inspection lines 60 are distributed sequentially from top to bottom along the outer edge 31, for example: the shape and size of the outer edge 31 of the tooling plate 30 and When the radian is small, only one inspection line 60 is needed, and the inspection line 60 extends from the upper end to the lower end of the tooling plate 30, such as figure 2 Shown; and when the shape size and radian of the outer edge 31 of tooling plate 30 are larger, as image 3 As shown, two inspection lines 60 are set, one of which extends from the upper end to the middle of the tooling plate 30, and the other extends from the middle to the lower end of the tooling plate 30. Before installing the tooling plate 30, it is necessary to ensure that the straightness of the two inspection lines 60 is ≤ 1mm, so as to ensure the accuracy of the entire tooling plate 30. The tooling plate 30 can be used repeatedly, and the straightness of the inspection line 60 needs to be checked before each use, and generally can be used repeatedly for three ships.
[0046] In order to ensure the cutting accuracy and marking accuracy of the tooling plate 30, in step b, the tooling plate 30 is CNC-cut and powder-sprayed and marked by a CNC cutting machine. Yangchong point 70 is convenient for the follow-up powder spraying line to be retrieved and remarked after wear. There are two groups of oceanic points 70 on each straight line, and each group of oceanic points 70 includes three points, and the two groups of oceanic points 70 are respectively set at the head end and tail end of the straight line. When the straight line is longer, such as the inspection line 60, only one group of foreign punching points 70 need to be marked on the head end and the tail end, and it is not necessary to mark the foreign punching points 70 along the whole straight line.
[0047] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the technical field, various modifications can be made without departing from the gist of the present invention. kind of change.
