Tooling for assembly of marine buoy angle profile frame

technical field

The invention relates to the field of buoy manufacture, and mainly relates to a tooling used for assembling an internal angle profile frame of an ocean buoy, which performs limit and controller welding deformation for the assembly of the angle profile frame.

Background technique

Ocean buoys are automatic observation stations for ocean hydrology, water quality and meteorology that are mainly composed of observation buoys anchored at sea. It can continuously and continuously collect marine hydrology, water quality and meteorological data for marine scientific research, offshore oil (gas) development, port construction and national defense construction in accordance with regulations, especially for the collection of severe weather and sea conditions that are difficult for survey ships to collect. material.

At present, in order to solve the insufficient corrosion resistance of steel buoys and the interference of material magnetism on the monitoring and collection of marine meteorological data, titanium alloy buoys can be used to make buoys. Whether it is a steel buoy or a titanium alloy buoy, the corner profile frame is an important part of the buoy structure.

Based on the structural characteristics of titanium alloy buoys, it is more reasonable, economical and efficient to adopt the positive manufacturing method, that is, the assembly sequence from bottom to top and from inside to outside. However, if this scheme is adopted, the accuracy of the outer dimensions of the angle titanium frame must be strictly controlled so that it can be used as a benchmark for subsequent assembly to ensure the assembly quality of the titanium alloy buoy structure.

At the same time, the structures of the 3-meter, 6-meter and 10-meter steel marine monitoring buoys currently used in large quantities in my country all have angle profile frame structures similar to angle titanium frame structures and functions.

As an important part of marine buoys, the corner profile frame plays a benchmark role in the subsequent assembly process, and its dimensional accuracy after assembly and welding directly affects the overall quality of the buoy. If ordinary three-dimensional platforms and fixtures are used, manual scribing and clamping assembly, the production efficiency is low, and the assembly accuracy and welding deformation of the corner profile frame cannot be ideally controlled, and distortion and deformation after welding and insufficient assembly dimensional accuracy are prone to occur.

Therefore, whether it is a titanium alloy buoy or a steel buoy, the assembly accuracy of the corner profile frame and the control of welding deformation are important factors that affect the overall quality of the buoy.

Detailed ways

The present invention will be further described in detail below in conjunction with the drawings and embodiments, but it is not used as a basis for any limitation on the invention.

This embodiment relates to the assembly of an internal angular titanium frame of a 6-meter-sized all-titanium marine buoy.

The specifications of the above-mentioned buoys are marine buoys with a diameter of 6 meters and all made of titanium alloy. As shown in Figure 1, the structure of the buoy is composed of a central instrument compartment and 6 independent watertight compartments 1 on the periphery. Angled titanium frames 2 are arranged inside the watertight compartment 1 to ensure the rigidity and stability of the overall structure. sex.

In order to reduce production costs and improve construction efficiency, the buoy adopts a positive manufacturing scheme, that is, the manufacturing scheme of assembling the structure from bottom to top and from inside to outside. The characteristic of this scheme is that it makes full use of the rigidity and profile position of the angle titanium frame 2 inside the buoy to provide a reference for positioning, marking and installation for the assembly of the shell plate. That is, the buoy shell plate is used as a skin, and is attached to the internal angular titanium frame 2 . 18 sets of L75×50×6 angle titanium frames 2 are arranged inside the watertight compartment 1 of the titanium alloy buoy.

Using the middle longitudinal section of the buoy shell, as shown in Figure 2, select the four corners 3 inside the buoyancy chamber at the bow or stern, delete the rest of the parts, and obtain the assembly positions of the four corners 3. Four angle titanium 3 and four connecting brackets 4 form a quadrangle as shown in FIG. 3 , that is, the angle titanium frame 2 .

According to the assembly position of the angle titanium 3 above, the limit block 5 is designed. Limiting blocks are arranged at each vertex of the quadrilateral formed by the angular titanium 3 . The assembly position of the angle titanium 3 is controlled by the semi-closed limit groove 9 on the limit block 5 .

The limit block 5 is made of a thicker plate, and the thickness of the plate is selected in consideration of a certain rigidity after processing, and considering the installation position of the connecting bracket 4, a 45mm thick plate is selected. In order to facilitate the installation of the connecting bracket 4 and the stability of the angle titanium 3, the processing depth of the limiting groove 9 is 30 mm. The width of the limiting groove 9 is based on the wider panel of the angle titanium 3 to be assembled. At the same time, the bending degree of the angle titanium of L75×50×6 is required to be ≤1mm/m; the twisting degree is ≤1mm/1000m. Type-qualified angle titanium can be easily loaded, and the width of the limit groove 9 is set to 78mm. The length of the groove should be greater than or equal to 50mm in consideration of stably fixing the angle titanium 3 at each position.

The limiting groove 9 is arranged on the back side of the limiting block 5, and each limiting block 5 is provided with two limiting grooves 9, and there is an interval 13 between the two limiting grooves 9, two The plane on the same side of the limiting groove 9 is the placing part 10 for placing the connecting bracket 4 , so the shape of the placing part 10 is adapted to the shape of the connecting bracket 4 .

The limit block 5 is processed by a horizontal milling machine end mill, because the limit groove 9 has a large processing depth and belongs to a semi-closed groove, so when processing, it is milled in two times to reach the required depth. Simultaneously, owing to there is the very short situation of two spacer grooves 9 intervals, therefore can only be milled to groove depth by the outer end of groove, expand milling groove both sides after groove deep milling. Pay attention to the feed rate when expanding milling, and avoid down milling to avoid damage to the milling cutter and damage the thin interlayer of the groove.

The tooling of the present invention also includes four connecting slats 6, each connecting slat 6 is connected to two limit blocks 5, so that the limit block 5 and the connecting slats 6 form a joint that is compatible with the shape of the corner profile frame. Assemble the frame. The width of the connecting lath 6 is wider than that of the Angle Titanium 3 panel, which is 115mm. The positioning bolts 7 are used for positioning to realize the fixed connection between two connecting slats 6 and a limiting block 5 , and the connecting slats 6 are connected to the front of the limiting block 5 .

The tooling of the present invention also includes limit pressure plates 8 arranged and used in pairs, each pair of limit pressure plates 8 is composed of a T-shaped pressure plate 11 and an L-shaped pressure plate 12, and the T-shaped pressure plate 11 is installed on the connecting strip 6 by screws , when installing the angle titanium 3, the apex of the angle titanium 3 is at the right angle of the T-shaped pressure plate 11, and then the L-shaped pressure plate 12 is inverted so that one surface of the L-shaped pressure plate 12 is pressed against the angle titanium 3 On the plate surface, the L-shaped pressing plate 12 is fixed on the connecting strip 6 with screws, so that the T-shaped pressing plate 11 and the L-shaped pressing plate 12 form a position-limiting mechanism capable of clamping the angle titanium 3, from the horizontal direction and the vertical direction. The direction is limited to the angle titanium 3, so as to control the welding deformation.

When using the tooling of the present invention to assemble the angle titanium, the surface of the angle titanium 3 should be cleaned and straightened, and then loaded into the tool after passing the test.

The angle titanium frame 2 also includes a connecting bracket 4, which can connect the two ends of the adjacent angle titanium 3, and after the angle titanium 3 is placed, the connecting bracket 4 is placed on the limit block 5 The placement part 10 of the connecting bracket 4 and the plate surface of the angle titanium 3 are contacted and welded, so that the welding assembly position can be found directly, and the marking process is eliminated, and then the connecting bracket 4 and the angle titanium 3 are welded and formed to obtain the required The Angle Titanium Frame 2. During the welding process, since the tooling of the present invention has good rigidity and can be positioned and limited from the end and middle of the angle titanium 3, the welding deformation can be well controlled.

After inspection, the angular titanium frame obtained by using the tooling of the present invention has a dimension deviation of ≤2mm, and the flatness is controlled within 2mm, the molding quality is good, and the assembly requirements are fully met. At the same time, through comparison, the assembly efficiency of the angular titanium frame is greatly improved by adopting the tooling of the present invention. It provides a good construction foundation for the subsequent installation of parts such as bilge plates and bulwarks.

The steel buoys of 3 meters, 6 meters and 10 meters used in large quantities in my country all have angle steel frame structures similar to angle titanium frames. Assembly quality and efficiency.
