Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more particularly to shipbuilding jigs. Background Technology

[0002] A jig is a mold used to manufacture aluminum alloy workpieces with complex curvature. It can better control the shape of the aluminum alloy sheet to quickly manufacture various aluminum alloy workpieces that meet the requirements.

[0003] In the prior art, the jig includes a mounting plate, which is arc-shaped. An aluminum plate is provided on the upper side of the mounting plate, and a base plate and a support rod are provided on the lower side of the mounting plate. The upper side of the mounting plate is used to fit against the aluminum alloy sheet, and the aluminum alloy sheet can be bent according to the arc of the mounting plate by extrusion to generate an aluminum alloy workpiece that meets the requirements.

[0004] However, when the aluminum alloy workpiece is separated from the mounting plate and removed from the mold, the stress inside the aluminum alloy workpiece will concentrate at the edge due to the elimination of the constraint force. This can easily lead to severe wavy bending deformation at the edge, resulting in a deterioration in the processing quality of the aluminum alloy workpiece. Summary of the Invention

[0005] The purpose of this invention is to provide a shipbuilding jig, which solves the problem in the prior art that the aluminum alloy workpiece suffers from poor processing quality due to stress concentration at the edge after removal from the jig, resulting in deformation at the edge.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Shipboard racks, which include:

[0008] The tire frame body is arc-shaped and its concave side is used to fit the aluminum alloy sheet.

[0009] The end of the tire frame is located at the end edge of the tire frame body, and the edge of the aluminum alloy sheet is attached to the end of the tire frame.

[0010] A connecting component is disposed on the tire frame body and detachably connected to the end of the tire frame; and

[0011] The fixing mechanism includes a first fixing component disposed on the body of the tire frame and a second fixing component disposed at the end of the tire frame, both of which are fixedly connected to the aluminum alloy sheet.

[0012] Optionally, the connection component includes:

[0013] A connecting plate is disposed on the end edge of the tire frame body and partially corresponds to the end of the tire frame; and

[0014] Fasteners are provided on the connecting plate and detachably connected to the end of the frame.

[0015] Optionally, the fasteners are spaced out in multiples.

[0016] Optionally, the first fixing component includes:

[0017] A fixing plate is fixed to the aluminum alloy sheet; and

[0018] A fastener is provided on the fixing plate and connected to the frame body.

[0019] Optionally, the fixing plate is an aluminum plate.

[0020] Optionally, the fixing plate is welded and fixed to the aluminum alloy sheet.

[0021] Optionally, the fastener is a spiral puller.

[0022] Optionally, multiple first fixing components are distributed at intervals along the body of the tire frame.

[0023] Optionally, the shipboard frame further includes:

[0024] A support frame is disposed on the side of the jig body away from the aluminum alloy sheet.

[0025] Optionally, the support frame includes:

[0026] Base plate;

[0027] Multiple support rods, one end of which is fixedly connected to the base plate and the other end of which is fixedly connected to the frame body.

[0028] The beneficial effects of this invention are:

[0029] By connecting the end of the jig to the jig body using a connecting assembly, the aluminum alloy sheet can be attached to the jig body, ensuring that the edges of the aluminum alloy sheet align with the end of the jig. A first fixing assembly secures the aluminum alloy sheet to the jig body, while a second fixing assembly secures the edges of the aluminum alloy sheet to the end of the jig. This allows the aluminum alloy sheet to be processed to produce a workpiece that meets the requirements. After processing, the first fixing assembly can be disassembled, and then the end of the jig can be separated from the jig body using the connecting assembly. This allows the aluminum alloy sheet to separate from the jig body along with the end of the jig, completing the removal from the jig. After removal, the end of the jig maintains a constraint force on the edges of the aluminum alloy workpiece. This ensures that the constraint force at the edges of the aluminum alloy workpiece remains unchanged after removal from the jig, reducing the possibility of deformation at the edges and effectively improving the processing quality of the aluminum alloy workpiece. Furthermore, the detachable connection between the jig body and the end of the jig allows the end of the jig to be reused, effectively improving the utilization efficiency of the jig end.

[0040] This invention discloses a shipboard tire frame.

[0041] Reference Figure 1 The shipboard jig includes a jig body 1, a jig end 2, a connecting assembly 3, and a fixing mechanism. The jig body 1 is arc-shaped with a concave side for fitting with an aluminum alloy sheet 7; the jig end 2 is located at the end edge of the jig body 1, and the edge of the aluminum alloy sheet 7 fits against the jig end 2; the connecting assembly 3 is located on the jig body 1 and detachably connected to the jig end 2; the fixing mechanism includes a first fixing assembly 4 located on the jig body 1 and a second fixing assembly 5 located on the jig end 2, both of which are fixedly connected to the aluminum alloy sheet 7.

[0042] Specifically, both the jig body 1 and the jig end 2 are made of steel, such as channel steel, and are long and curved with an upward curve. The specific curvature can be designed according to processing requirements, and this invention does not limit it. The connecting component 3 is set on the side of the jig body 1, and two sets of the connecting component 3 can be set, one set on each side of the jig body 1, so as to make the connection stability between the jig end 2 and the jig body 1 better. The first fixing component 4 and the second fixing component 5 can adopt the same structure, the only difference being their position and the order of disassembly. Depending on the length of the jig body 1, multiple first fixing components 4 can be distributed at intervals to ensure the connection strength between the aluminum alloy sheet 7 and the jig body 1, while only one second fixing component 5 can be set, or multiple second fixing components can be set at intervals. This invention does not limit the number of first fixing components 4 and second fixing components 5.

[0043] By connecting the end 2 of the jig to the jig body 1 using the connecting component 3, the aluminum alloy sheet 7 can be attached to the jig body 1, ensuring that the edge of the aluminum alloy sheet 7 corresponds to the end 2 of the jig. The first fixing component 4 fixes the aluminum alloy sheet 7 to the jig body 1, while the second fixing component 5 fixes the edge portion of the aluminum alloy sheet 7 to the end 2 of the jig. The aluminum alloy sheet 7 can then be processed to produce a qualified aluminum alloy workpiece. After processing, the first fixing component 4 can be disassembled, and then the end 2 of the jig can be separated from the jig body 1 using the connecting component 3. This allows the aluminum alloy sheet 7 to separate from the jig body 1 along with the end 2 of the jig, thus completing the removal from the jig. After removal, the end 2 of the jig maintains a constraint force on the edge of the aluminum alloy workpiece. This ensures that the constraint force at the edge of the aluminum alloy workpiece remains unchanged after removal from the jig, reducing the possibility of deformation at the edge and effectively improving the processing quality of the aluminum alloy workpiece. Furthermore, the detachable connection between the tire frame body 1 and the tire frame end 2 allows the tire frame end 2 to be reused, effectively improving the utilization efficiency of the tire frame end 2.

[0044] Reference Figure 2 and Figure 3 Optionally, the connecting assembly 3 includes a connecting plate 31 and fasteners 32. The connecting plate 31 is disposed on the end edge of the carcass body 1 and partially corresponds to the end of the carcass 2; the fasteners 32 are disposed on the connecting plate 31 and detachably connected to the end of the carcass 2. Multiple fasteners 32 are spaced apart.

[0045] Specifically, the connecting plate 31 is rectangular and made of steel. It can be fixed to the side of the frame body 1 or detachably connected to the frame body 1. One side of the connecting plate 31 extends out of the frame body 1 to correspond to the side of the frame end 2. The fastener 32 can be a bolt, which passes through the connecting plate 31 and through the frame end 2. A nut is provided on the side of the bolt that passes through the frame end 2. Multiple fasteners 32 can be spaced apart to ensure the connection strength between the connecting plate 31 and the frame end 2. In this embodiment, the connecting plate 31 and the frame body 1 are also detachably connected by the fastener 32 to facilitate the installation and removal of the connecting plate 31.

[0046] By setting up the connecting plate 31 and fasteners 32, when it is necessary to connect the end 2 of the frame to the body 1 of the frame, the connecting plate 31 is attached to the body 1 of the frame and the end 2 of the frame respectively, and then multiple fasteners 32 are passed through the connecting plate 31 in sequence, so that the end 2 of the frame and the body 1 of the frame can be installed together. When it is necessary to disassemble, it is only necessary to remove the multiple fasteners 32 from the connecting plate 31 to quickly separate the body 1 of the frame and the end 2 of the frame.

[0047] Reference Figure 1 Optionally, the first fixing component 4 includes a fixing plate 41 and a fixing member 42. The fixing plate 41 is fixed to the aluminum alloy sheet 7; the fixing member 42 is disposed on the fixing plate 41 and connected to the jig body 1, and the fixing member 42 is a spiral puller. The fixing plate 41 is an aluminum plate. The fixing plate 41 is welded and fixed to the aluminum alloy sheet 7.

[0048] Specifically, the fixing plate 41 is made of aluminum and can be fixed to the aluminum alloy sheet 7 by spot welding. The fixing plate 41 is located on the side of the aluminum alloy sheet 7 near the jig body 1, and the fixing member 42 is fixedly connected to the fixing plate 41 at one end and to the jig body 1 at the other end. A spiral puller is used as the fixing member 42 to effectively improve the connection strength between the aluminum alloy sheet 7 and the jig body 1. The second fixing component 5 has the same structure as the first fixing component 4, and the structure of the second fixing component 5 will not be described in detail here.

[0049] When the aluminum alloy sheet 7 is placed on the tire frame body 1, the fixing plate 41 is first fixed to the aluminum alloy sheet 7 by spot welding. Then, the fixing member 42 is set and connected to the tire frame body 1, thus quickly achieving a fixed connection between the aluminum alloy sheet 7 and the tire frame body 1. When tire removal is required, the fixing member 42 is removed, and the aluminum alloy sheet 7 can be separated from the tire frame body 1, thus successfully completing the tire removal.

[0050] Reference Figure 4 Optionally, the marine jig also includes a support frame 6. The support frame 6 is located on the side of the jig body 1 away from the aluminum alloy sheet 7.

[0051] Specifically, the support frame 6 includes a base plate 61 and multiple support rods 62. One end of each support rod 62 is fixedly connected to the base plate 61, and the other end is fixedly connected to the frame body 1. The fixing method can be welding or bolting. Both the base plate 61 and the support rods 62 are made of steel. The base plate 61 is fixed to the bottom surface or other equipment, while the support rods 62 extend vertically. Multiple support rods 62 are distributed at intervals along the length of the frame body 1. As the curvature of the frame body 1 changes, the height of the support rods 62 can also change accordingly to reduce overall material consumption and manufacturing costs.

[0052] The specific implementation principle of this embodiment is as follows:

[0053] First, the base plate 61 and the support rod 62 are welded together to form a support frame 6. Then, the jig body 1 is fixed on the upper side of the support frame 6, with the concave surface of the jig body 1 facing upwards to place the aluminum alloy sheet 7. Before processing the aluminum alloy sheet 7, the jig end 2 is aligned with the end face of the jig body 1. Then, the connecting plate 31 is placed, and multiple fasteners 32 are sequentially installed to fix the connecting plate 31 to the jig body 1 and the jig end 2, thereby fixing the jig end 2 to the jig body 1 together.

[0054] After fixing the end 2 of the jig frame and the jig frame body 1, the aluminum alloy sheet 7 can be placed on the concave side of the jig frame body 1, and the edge of the aluminum alloy sheet 7 should be aligned with the end 2 of the jig frame. Then, the first fixing component 4 and the second fixing component 5 are set in sequence to fix the aluminum alloy sheet 7 to the jig frame body 1 and the end 2 of the jig frame, so that the aluminum alloy sheet 7 can be processed.

[0055] When the aluminum alloy sheet 7 is processed to form an aluminum alloy workpiece and is removed from the mold, the first fixing component 4 is first removed, and then the fastener 32 on the connecting plate 31 is removed. At this time, the mold end 2 and the aluminum alloy workpiece can be removed as a whole, so that the mold end 2 can maintain the constraint force on the edge position of the aluminum alloy workpiece, thereby reducing the possibility of deformation at the edge position of the aluminum alloy workpiece and effectively improving the processing quality of the aluminum alloy workpiece.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
