Description

Technical Field

[0001] This utility model belongs to the technical field of liquefied natural gas (LNG) insulation box production equipment, specifically relating to a multi-functional processing device for a single slide block of an insulation box workpiece. Background Technology

[0002] With the accelerated energy transition, global liquefied natural gas (LNG) trade is projected to grow from 250 million tons in 2010 to 450 million tons in 2024, driving a continuous increase in LNG carrier orders. The cargo containment system is a core component of the LNG carrier's cargo tanks, responsible for the safe storage of LNG at ultra-low temperatures of -163°C. Key components of the cargo containment system include insulating boxes that provide thermal insulation. The manufacturing process of these insulating boxes involves complex and diverse machining steps, including the cutting and precision milling of various materials. For example, the foam core material requires irregular contour cutting with tolerances controlled within ±0.5mm; while the splicing surfaces of composite panels require high-precision milling to ensure a perfect fit.

[0003] For insulation boxes, the current industry standard for processing is "cutting-transfer-milling." The cutting process relies heavily on specialized sawing equipment, which is typically only capable of straight or simple angle cuts; complex machining requires multiple clamping and adjustments. The milling process uses a three-axis machining center, which cannot also perform sawing. This step-by-step processing method using different equipment presents three main problems:

[0004] First, the process changeover is time-consuming. Processing a single box requires 3-4 equipment changes, resulting in a significant amount of auxiliary time, which severely restricts production efficiency.

[0005] Secondly, the repeatability error is large, and the positioning deviation caused by multiple clamping can reach 0.3mm-0.8mm, which is difficult to meet the requirements of high-precision assembly.

[0006] Third, the equipment utilization rate is low. The load rate of dedicated sawing equipment and processing center is only 45% and 60% respectively, and independent loading and unloading areas are required, increasing the workshop floor area by more than 30%.

[0007] As the construction cycle of LNG carriers continues to shorten, the efficiency bottleneck of existing processing equipment is becoming increasingly apparent. Data from a major domestic shipyard shows that the insulation box processing stage has become a critical bottleneck in the production of LNG cargo containment systems, with equipment capacity falling short by 40%, directly leading to delays in the delivery of some orders. Simultaneously, the increased manual intervention in the step-by-step processing model has not only increased labor costs by 30% but also resulted in approximately 2% of workpieces being scrapped due to operational errors, further pushing up production costs. Therefore, developing high-efficiency processing equipment capable of integrating cutting and milling functions has become an urgent need to overcome the bottleneck in LNG carrier insulation box production.

Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes in detail the multi-functional processing device for single slide ram of insulating box workpiece of this utility model in conjunction with the embodiments and accompanying drawings.

[0027] Example

[0028] This embodiment provides a multi-functional single-slide machining device for insulating box workpieces, used to process insulating box workpieces that constitute LNG cargo tanks. It solves the problem of cumbersome processing procedures for insulating boxes, improves processing efficiency, and reduces processing costs. To facilitate explanation of the device's structure and function, the structure of the workpiece and processing requirements will be briefly described below.

[0029] Figure 3 This is a schematic diagram of the structure of an insulating box workpiece in the prior art.

[0030] like Figure 3 As shown, the insulating box workpiece 20 includes a workpiece body 21 and multiple wedges 22.

[0031] The workpiece body 21 has a three-layer composite structure, with a middle layer of polyurethane foam board 211 (foam core material) and upper and lower layers of wood-based panels 212. The upper surface of the workpiece body 21 has multiple elongated grooves 213. Each of the four corners of the workpiece body 21 has a right-angle groove 214, with chamfered corners at the inner angles of the right-angle grooves 214. Furthermore, the upper surface and sides of the workpiece body 21 have multiple mounting holes (not shown in the figure).

[0032] The wedge 22 is made of wood and consists of a long wooden board and two wooden strips. The whole is roughly U-shaped with right angles. The two wooden strips are respectively embedded and fixed in two right-angled grooves 214 at one end of the workpiece body 21.

[0033] The device provided in this embodiment is used to give the workpiece body 21 more precise dimensions by sawing and milling the plane, and to process the above-mentioned elongated groove 213, right-angle groove 214, and assembly hole. Although existing five-axis machine tools can also achieve these processing requirements, the insulation box workpiece is very large, requiring a large diameter circular saw blade for processing, resulting in a large spindle of the five-axis machine tool and excessive cost.

[0034] Insulation box workpieces come in many other shapes, but the processing requirements are quite similar.

[0035] Figure 1 This is a schematic diagram of the multi-functional processing device for a single slide block of an insulating box workpiece in this embodiment. Figure 2 yes Figure 1 Enlarged view of the inner part of frame A.

[0036] like Figure 1 and Figure 2 As shown, the multi-functional machining device 100 for single slide blocks of insulating box workpieces includes: a worktable 11, a support mechanism 12, a machining mechanism 13, and a tool magazine 14.

[0037] The worktable 11 is flat, with its upper surface being essentially planar, and is used to hold the raw material plate or insulation box workpiece to be processed. Appropriate tooling can be used to position the insulation box workpiece on the worktable 11; such tooling includes, for example, locating pins and locating blocks.

[0038] The support mechanism 12 provides support for the worktable 11 and the processing mechanism 13, and includes a base 121, two columns 122, and a crossbeam 123. The base 121 is generally a flat plate with a groove in the middle, and the worktable 11 is embedded in the groove in the middle of the base 121. The two columns 122 are generally inverted T-shaped and are respectively disposed on both sides of the base 121, located on both sides of the worktable 11 in the width direction. The two ends of the crossbeam 123 are respectively disposed on the upper ends of the two columns 122, and the crossbeam 123 is positioned above the worktable 11, with its length direction extending along the width direction of the worktable 11.

[0039] The machining mechanism 13 is used to perform various machining operations on the insulation box workpiece, including sawing and cutting. Cutting operations can include milling and drilling. The machining mechanism 13 includes: a slide 131, a slide drive mechanism (not shown in the figure), a three-axis machining assembly 132 (cutting assembly), and a four-axis machining assembly 133 (sawing assembly). That is, the device in this embodiment is a combined three-axis and four-axis machining device.

[0040] The three-axis machining assembly 132 and the four-axis machining assembly 133 are both mounted on the slide 131, which is slidably mounted on the crossbeam 123 to drive the two machining assemblies to move along the length of the crossbeam 123 (i.e., along the horizontal direction). The slide drive mechanism can adopt corresponding structures in the prior art, such as those including servo motors and lead screws.

[0041] The three-axis machining assembly 132 is used for milling, chamfering, grooving, and drilling on the upper surface and sides of the insulation box workpiece. For example, it includes milling the entire insulation box workpiece onto the upper plane and sides to give it more precise dimensions; chamfering the edges of the insulation box workpiece; and grooving and drilling at predetermined positions on the upper surface and sides of the insulation box workpiece, etc. The three-axis machining assembly 132 includes a first slide 1321, a first cylinder 1322, a three-axis power head 1323 (cutting power head), and a machining tool 1324.

[0042] The first slide 1321 is slidably mounted on the slide block 131 in a vertical direction, that is, the first slide 1321 can be raised and lowered. For example, a vertical guide rail is provided on the outer surface of the slide block 131, and the first slide 1321 has a groove that matches the guide rail and is slidably mounted on the guide rail.

[0043] The first cylinder 1322 is mounted on the slide block 131 and located above the first slide table 1321. Its piston rod is connected to the upper end of the first slide table 1321 and is used to drive the first slide table 1321 to move up and down.

[0044] The three-axis power head 1323 is fixedly mounted on the first slide 1321, and the machining tool 1324 is detachably mounted on the lower end of the first slide 1321. The three-axis power head 1323 can drive the cutting tool 1324 to move along three motion axes, thereby machining the insulating box workpiece placed on the worktable 11. The cutting tool 1324 can be a surface machining tool (e.g., a milling tool) or a hole machining tool (e.g., a drilling tool), and can be any of these types of tools, depending on the edge structure, groove structure, hole structure, etc. to be machined.

[0045] The four-axis machining assembly 133 is used to perform transverse and longitudinal sawing operations on the insulation box workpiece, such as cutting the raw material board into multiple pieces; sawing the side of the insulation box workpiece, etc. The four-axis machining assembly 133 includes a second slide 1331, a second cylinder 1332, a four-axis power head 1333 (a power head for sawing), and a circular saw blade 1334.

[0046] The second slide 1331 is slidably mounted on the slide block 131 in a vertical direction. For example, a vertical guide rail is provided on the outer surface of the slide block 131, and the second slide 1331 has a groove that matches the guide rail and is slidably mounted on the guide rail. That is, the first slide block 1321 and the second slide block 1331 can be raised and lowered independently.

[0047] The second cylinder 1332 is mounted on the slide block 131 and located above the second slide table 1331. Its piston rod is connected to the upper end of the second slide table 1331 and is used to drive the second slide table 1331 to move up and down.

[0048] The four-axis power head 1333 is fixedly mounted on the first slide table 1321. The circular saw blade 1334 is mounted on one side of the lower end of the four-axis power head 1333, and is located on both sides of the four-axis power head 1333, respectively, to avoid interference during processing. The four-axis power head 1333 can drive the circular saw blade 1334 to rotate and move it along three motion axes, thereby cutting the insulating box workpiece placed on the worktable 11. In this embodiment, the diameter of the circular saw blade 1334 is relatively large, greater than or equal to 1m.

[0049] Tool magazine 14 is located at the lower part of one of the columns 122. Tool magazine 14 is a hat-shaped tool magazine used to accommodate (store) multiple different replacement cutting tools, so as to provide different tools for the three-axis power head 1323 and ensure that the appropriate tool can be changed for the three-axis power head 1323 in a timely manner according to the machining requirements. The replacement cutting tools can also be surface machining tools (e.g., milling tools) or hole machining tools (e.g., drilling tools), and all replacement cutting tools are matched with the three-axis power head 1323. In this embodiment, the cutting tools and replacement cutting tools include at least milling cutters for milling planes, milling cutters for chamfering, turning tools or milling cutters for grooving, and drilling tools for drilling.

[0050] Three-axis power heads, four-axis power heads, tool magazines, and cutting tools can all adopt corresponding structures from existing technologies, so they will not be elaborated further.

[0051] In use, the first cylinder 1322 and the second cylinder 1332 cause one of the three-axis power head 1323 and the four-axis power head 1333 to descend as the current machining power head, while the other remains at its initial height, and then the corresponding machining is performed using the machining power head.

[0052] by Figure 3Taking the insulation box workpiece 20 as an example, a four-axis machining assembly 133 (sawing assembly) can be used to cut a large raw material plate into multiple plates 212; the four-axis machining assembly 133 can also be used to saw the sides of the insulation box workpiece 20. The three-axis power head 1323 can be replaced with the corresponding cutting tools in sequence, and the three-axis machining assembly 132 can be used to perform milling of the upper and side surfaces of the insulation box workpiece 20, chamfering of the edges, cutting of long grooves 213 and right-angle grooves 214, drilling of assembly holes, etc., thereby covering a variety of machining operations required for the insulation box workpiece.

[0053] The role and effect of the embodiments

[0054] The multi-functional processing device for insulating box workpieces provided in this embodiment, with its slide, sawing component, and cutting component, can perform sawing and cutting on insulating box workpieces, including milling, grooving, and drilling. A single device can cover various processing needs of insulating boxes, eliminating the need for multiple processing equipment and workpiece transfer between equipment, thus effectively reducing processing steps and improving efficiency. Since the same device covers all processing steps, and because sawing and cutting do not need to be performed simultaneously, the sawing component and cutting component can be mounted on the same slide, significantly reducing the processing cost of insulating boxes. In summary, this embodiment provides strong equipment support for insulating box processing, improving processing efficiency and reducing processing costs.

[0055] Furthermore, since the sawing assembly uses a four-axis conventional power head and the cutting assembly uses a three-axis conventional power head, compared with a five-axis machine tool, it can significantly reduce equipment costs while fully meeting processing requirements.

[0056] Furthermore, since each of the two processing components has a slide and a cylinder, one of the power heads can be lowered to serve as the processing power head, while the other power head remains at its original height. At the same time, the larger diameter circular saw blade is positioned on the outside. Therefore, the sawing processing component and the cutting processing component can be mounted on the same slide and do not interfere with each other during processing, making it convenient to use.

[0057] Furthermore, since a hat-shaped tool magazine is installed on one side of the worktable, storing multiple different replacement cutting tools, the appropriate tool can be replaced for the three-axis power head in a timely manner according to the machining requirements, thereby further improving machining efficiency.

Those skilled in the art should understand that the utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only for illustrating the principles of the utility model.
