Description

TECHNICAL FIELD

[0001] The present application relates to a kind of special tools for ship plate splicing, which belongs to the technical field of ship plate welding. BACKGROUND

[0002] The existing ship plate splicing generally adopts the process of positioning horse plate positioning and assembling horse plate adjustment to position and correct the work of ship plate splicing. The operation process is generally to place the plate to be spliced on the rack, adjust the two plates to be spliced to the splicing position, adjust the butt joint gap of the two plates to be spliced, and weld the positioning horse at the end of the plate. Since the plate itself is flexible, the planes of the two plates at the splicing position may not be on the same plane, which is called misalignment in the industry. In order to adjust the misalignment, an angle iron (a kind of assembling horse) is used to adjust the two plates to within the standard range (1 / 3 of the thickness of the thin plate is required by the specification). After adjustment, the butt joint of the two plates is welded. After welding, the angle iron and horse plate on both sides of the weld are removed. Removal is generally by carbon planing or oxyacetylene flame cutting. After removal, repair welding or polishing is required to ensure that the removed horse plate part is defect-free.

[0003] The existing ship plate splicing generally adopts the process of positioning horse plate positioning and assembling horse plate adjustment to position and correct the work of ship plate splicing. Since the horse plate needs to be welded on the outer plate, the horse plate needs to be removed after the outer plate splicing is welded. Removal is generally by carbon planing or oxyacetylene flame cutting. After removal, repair welding or polishing is required to ensure that the removed horse plate part is defect-free. The present application mainly solves the problem of not needing to weld the horse plate on the outer plate and reduces the damage and repair work caused by horse plate welding and removal.

[0004] Since horse plate welding is a temporary welding, it is generally removed by repair welding and polishing after welding. During the welding of the tool, invisible welding defects may extend into the steel plate. After the horse plate is removed, defects may be left, affecting the properties of the plate. In the horse plate removal stage, there is a lot of repair work, which takes a long time and there are invisible defects left in the steel plate. SUMMARY

[0005] To solve the problems in the prior art, the present application provides a special tool for ship plate splicing, which avoids the welding of the outer plate horse plate and the repair work caused by the removal of the horse plate.

[0006] The technical scheme adopted by the present application is: a special tool for ship plate splicing, characterized in that: the tool includes two tool unit chains arranged in mirror image on a first splicing plate and a second splicing plate, and the two tool unit chains are locked by chain heads. Two adjacent tool units in the tool unit chain are connected by a connecting handle; The tool unit comprises a tool shell, a magnetic attraction structure and a chain tooth structure. The middle support plate of the magnetic attraction structure is fixed in the tool shell. A puzzle support plate with a magnet movable hole is arranged below the middle support plate. A permanent magnet is fixedly installed below the magnet connecting plate. The magnet connecting plate passes through the magnet movable hole and moves up and down in the magnet movable hole. The magnet lifting shaft passing through the middle support plate is fixed above the magnet connecting plate. The magnet lifting shaft passes out of the end of the tool shell and is connected to a demagnetization handle. When the demagnetization handle is pulled from vertical to horizontal, the magnet lifting shaft is pulled upward, thereby driving the magnet connecting plate to move upward in the magnet movable hole. The magnet connecting plate drives the permanent magnet to move upward away from the surface of the puzzle, thereby demagnetizing. When the demagnetization handle is pulled from horizontal to vertical, the magnet lifting shaft moves downward, thereby driving the magnet connecting plate to move downward in the magnet movable hole. The magnet connecting plate drives the permanent magnet to move downward. The permanent magnet is attracted to the surface of the puzzle and is magnetically attracted. One end of the chain tooth in the chain tooth structure is fixed on the top surface of the tool shell, and the other end is a suspended engagement head. A chain tooth guide block that acts on the chain head is further arranged on the chain tooth.

[0007] Further, the bottom of the demagnetization handle is a volute structure. The distance h from the rotation point of the demagnetization handle to the tool shell when the demagnetization handle is vertical is less than the distance H from the rotation point of the demagnetization handle to the tool shell when the demagnetization handle is horizontal.

[0008] Further, 3-5 groups of magnetic attraction structures are arranged in the tool unit.

[0009] Further, 5-10 groups of chain tooth structures are arranged in the tool unit.

[0010] Further, a connecting handle hole is arranged on the outside of the tool shell. The connecting handle is fixed in the connecting handle hole by connecting handle bolts between two adjacent tool shells, thereby connecting the two tool shells.

[0011] Further, after the two tool unit chains are engaged by the chain head, the first puzzle and the second puzzle are at the same height. The gap between the first puzzle and the second puzzle is a welding seam area.

[0012] A working method of a special tool for a ship plate puzzle, comprising the following steps: a. Place the tool unit at the edge of the first puzzle. When the demagnetization handle is pulled from horizontal to vertical, the magnet lifting shaft moves downward, thereby driving the magnet connecting plate to move downward in the magnet movable hole. The magnet connecting plate drives the permanent magnet to move downward. The permanent magnet is attracted to the surface of the puzzle, and the tool unit is magnetically attracted to the first puzzle. The adjacent two tooling housings are connected by connecting the connecting handle in the connecting handle hole through the connecting handle bolt, and then the adjacent two tooling housings are connected, and the tool units are connected in sequence to form the tool unit chain on the first panel; b. When setting the tool unit on the second panel, the tool unit on the first panel is set in mirror image and staggered by one chain tooth; when the demagnetization handle is pulled from horizontal to vertical, the magnet lifting shaft moves downward, and then the magnet connecting plate moves downward in the magnet movable hole, the magnet connecting plate drives the permanent magnet to move downward, the permanent magnet is adsorbed to the panel surface, and the tool unit is magnetically adsorbed to the first panel; The adjacent two tooling housings are connected by connecting the connecting handle in the connecting handle hole through the connecting handle bolt, and then the adjacent two tooling housings are connected, and the tool units are connected in sequence to form the tool unit chain on the second panel; c. The chain teeth at the first ends of the first panel and the second panel are engaged, and the chain head is installed, the chain head is pulled, the side wall of the chain head acts on the chain tooth guide block of the chain tooth, and the tool unit chains on the first panel and the second panel are engaged; after engagement, the first panel and the second panel are at the same height, and the gap between the first panel and the second panel is a welding seam area; d. Weld the welding seam area, and after welding is completed; when the demagnetization handle in the tool unit is pulled from vertical to horizontal, the magnet lifting shaft is pulled upward, and then the magnet connecting plate moves upward in the magnet movable hole, the magnet connecting plate drives the permanent magnet to move upward and away from the panel surface, and demagnetization is performed; the tool units on the first panel and the second panel are removed respectively.

[0013] Compared with the prior art, the present application has the following advantages: two tool unit chains set in mirror image and staggered and the chain head of the locking chain are used, the magnetic attraction structure in the tool unit can control the permanent magnet to be adsorbed or separated from the panel by pulling the demagnetization handle, and the chain tooth structure has one end of the chain tooth fixed and the other end of the chain tooth as a hanging engagement head with a chain tooth guide block cooperating with the chain head. When working, the tool units are respectively magnetically adsorbed to the two panels and form the mirror image and staggered tool unit chains, and then the chain head engages the chain tooth to accurately position the two panels (at the same height and with a gap as a welding seam area), and the tool can be removed by pulling the demagnetization handle after welding is completed. The tool fundamentally avoids the welding operation of the outer plate horse plate in the traditional process and the damage and repair treatment of the outer plate caused by the removal of the horse plate, not only greatly saves the material, labor and time cost, improves the shipbuilding efficiency, but also guarantees the panel welding quality through accurate positioning and stable clamping, reduces the welding deformation, effectively solves the problems existing in the prior art, and realizes the high efficiency and high quality of the ship outer plate panel process.

[0014] During the assembly process, the two ends of the plates are first positioned using positioning brackets to ensure that the assembly gap between the two plates meets the welding requirements. At the locations where angle irons (assembly brackets) are originally required, a magnetic device is used to attach the special assembly tool to the area to be assembled. Then, the tool is used to adjust the misalignment of the assembled plates. After welding is completed, the tool is demagnetized and removed, eliminating the need for welding and post-weld repair work. Attached Figure Description

[0028] Figs. 1 to 3 A special tool for splicing ship outer plates is shown. The tool includes two tool unit chains arranged in a mirror-like staggered manner on the first splice plate 12 and the second splice plate 13. The two tool unit chains are locked with chain teeth 14 by chain heads 11. Two adjacent tool units in the tool unit chain are connected by a connecting plate 8. The tool unit includes a tool housing 1, a magnetic structure, and a chain tooth structure.

[0029] The intermediate support plate 6 of the magnetic structure is fixed inside the tooling housing 1. Below the intermediate support plate 6, a splicing support plate 4 with a magnet movable hole 16 is provided. The permanent magnet 2 is fixedly installed below the magnet connecting plate 5. The magnet connecting plate 5 passes through the magnet movable hole 16 and moves up and down within the magnet movable hole 16. Above the magnet connecting plate 5, a magnet lifting shaft 3 passes through the intermediate support plate 6. The end of the magnet lifting shaft 3 that extends out of the tooling housing 1 is connected to the demagnetizing handle 7. The bottom of the demagnetizing handle 7 has a volute-shaped structure. When the vertical direction is perpendicular, the distance h from the rotation point of the demagnetizing handle 7 to the tooling housing 1 is less than the distance H from the rotation point of the demagnetizing handle 7 to the tooling housing 1 when the horizontal direction is perpendicular.

[0030] When the demagnetizing handle 7 is moved from vertical to horizontal, the magnet lifting shaft 3 is pulled upward, which in turn drives the magnet connecting plate 5 to move upward within the magnet movable hole 16. The magnet connecting plate 5 drives the permanent magnet 2 to move upward away from the panel surface for demagnetization. When the demagnetizing handle 7 is moved from horizontal to vertical, the magnet lifting shaft 3 moves downward, which in turn drives the magnet connecting plate 5 to move downward within the magnet movable hole 16. The magnet connecting plate 5 drives the permanent magnet 2 to move downward, and the permanent magnet 2 is attracted to the panel surface for magnetic attraction. In the chain tooth structure, one end of the chain tooth 14 is fixed to the top surface of the tool housing 1, and the other end is a suspended biting head 17. The chain tooth 14 is also provided with a chain tooth guide block 15 that interacts with the chain head 11.

[0031] The tool unit has 3 sets of magnetic attraction structures. The tool unit has 8 sets of chain tooth structures.

[0032] A connecting plate hole 9 is provided on the outer side of the tool housing 1. The connecting plate 9 is fixed in the connecting plate 9 between two adjacent tool housings 1 by connecting plate bolts 10, thus connecting the two tool housings 1. The chain tooth 14 is a rigid structure, and the connection between the chain tooth 14 and the tool housing 1 is rigid, ensuring that after the two tool unit chains are engaged by the chain head 11, the first panel 12 and the second panel 13 are at the same height, and the gap between the first panel 12 and the second panel 13 is the weld area.

[0033] When using the above technical solution, the following steps are included: a. Place the tool unit at the edge of the first panel 12. When the demagnetizing handle 7 is moved from horizontal to vertical, the magnet lifting shaft 3 moves downward, which in turn drives the magnet connecting plate 5 to move downward in the magnet moving hole 16. The magnet connecting plate 5 drives the permanent magnet 2 to move downward, and the permanent magnet 2 is attracted to the surface of the panel. The tool unit is magnetically attracted to the first panel 12. The connecting plate 9 is fixed in the connecting plate 9 by the connecting bolt 10 between two adjacent tool housings 1, and the two adjacent tool housings 1 are connected, and the tool units are connected in sequence to form the tool unit chain on the first panel 12. b. When setting the tool unit on the second panel 13, it is mirrored on the tool unit on the first panel 12 and staggered by one chain tooth 14. When the demagnetizing handle 7 is moved from horizontal to vertical, the magnet lifting shaft 3 moves downward, which in turn drives the magnet connecting plate 5 to move downward in the magnet moving hole 16. The magnet connecting plate 5 drives the permanent magnet 2 to move downward, and the permanent magnet 2 is attracted to the surface of the panel. The tool unit is magnetically attracted to the first panel 12. The connecting plate 9 is fixed in the connecting plate 9 by the connecting plate bolt 10 between two adjacent tool housings 1, and the two adjacent tool housings 1 are connected, and the tool units are connected in sequence to form the tool unit chain on the second panel 13. c. Engage the chain teeth 14 at the beginning of the first panel 12 and the second panel 13, insert the chain head 11, pull the chain head 11, and the side wall of the chain head 11 acts on the chain tooth guide block 15 of the chain teeth 14, so that the tool unit chains on the first panel 12 and the second panel 13 engage. The first panel 12 and the second panel 13 are at the same height, and the gap between the first panel 12 and the second panel 13 is the weld area. d. Weld the weld area. After welding, when the demagnetizing handle 7 in the tool unit is moved from vertical to horizontal, the magnet lifting shaft 3 is lifted upward, which in turn drives the magnet connecting plate 5 to move upward in the magnet moving hole 16. The magnet connecting plate 5 drives the permanent magnet 2 to move upward away from the surface of the panel for demagnetization. Remove the tool units on the first panel 12 and the second panel 13 respectively.

[0034] Magnetic fixtures are used to adjust the misalignment of the assembled panels. The magnetic device is a small assembly unit that can be adjusted according to the length of the weld bead. The fixtures on the magnetic device ensure this. The fixtures adopt a zipper design, with each fixture being a tooth in the zipper. One side of the tooth is welded to the fixture housing. The zipper head is used to lock the teeth on both sides of the weld bead of the panel to be assembled. Since the height of each tooth is consistent, the panels on both sides will be on the same plane after locking, and will not be adjusted due to changes in the linearity of the outer panel.

[0035] This solution uses a magnetic device to attach a special tool for splicing panels to the part of the panel to be spliced. Then, the tool is used to adjust the misalignment of the panels. After welding is completed, the tool is demagnetized and removed, eliminating the need for welding and post-weld repair work.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
