Description

Technical Field

[0001] This invention relates to the field of shipbuilding, and specifically to an adaptive T-section welding clamping device and its usage method. Background Technology

[0002] During shipbuilding, the welding of T-sections has become much more convenient with the improvement of modern industrial production levels. However, there are still many defects, such as: unreasonable welding clamping equipment structure, which makes it impossible to properly limit and fix the profiles, resulting in deviations in the welded T-sections and failure to meet the expected accuracy standards, leading to material waste; in addition, the current processing of ship T-sections mostly relies on manual welding, and some automated processing equipment only supports the processing of ordinary T-sections. Some equipment cannot change the positioning settings of the positioning fixtures for T-sections in real time according to the actual size of the T-sections produced, resulting in insufficient flexibility in adjusting the positioning fixtures for T-sections of different sizes; moreover, some welding clamping equipment has a complex structure, unclear structural hierarchy, and unreasonable overall layout, which seriously affects the later maintenance and repair of the equipment, thereby increasing the maintenance cost of the equipment.

[0003] Patent No. CN212761834U, entitled "A T-profile Welding Production Equipment," addresses the issue of insufficient precision in T-profiles produced by welding equipment. It ensures effective positioning of the T-profile throughout the welding process, achieving the expected precision and providing an excellent user experience. Patent No. CN107717266A, entitled "An Automatic Assembly and Welding Device for Thin-Walled T-Profiles," addresses the problems of high production time and low efficiency in thin-walled T-profile manufacturing. It improves the production process, enabling automatic positioning, clamping, and welding of thin-walled T-profiles. This eliminates the previous need for manual marking, assembly spot welding, and post-weld deformation correction, allowing for assembly line operations, reducing T-profile manufacturing time, and improving overall efficiency. The patent, numbered CN215588256U and entitled "A Welding System for Bent T-Profiles," addresses the problem that existing bent T-profiles lack welding fixing devices, leading to welding difficulties and high labor intensity for workers. It improves the positioning accuracy and welding speed of bent T-profiles and reduces the labor intensity for workers.

[0004] However, most existing ship T-section processing equipment is designed for welding and clamping a single type of T-section and cannot process different types of T-sections simultaneously. Summary of the Invention

[0005] Purpose of the invention: The present invention provides an adaptive T-profile welding clamping device, which reduces the scheduling cost of T-profiles while improving the welding efficiency of T-profiles.

[0006] Technical solution: The present invention proposes an adaptive T-profile welding clamping device, including an equipment housing, a panel adaptive clamping device, a web adaptive clamping lifting platform, and a profile positioning adaptive clamping device; the panel adaptive clamping device and the web adaptive clamping lifting platform are arranged opposite to each other, and the profile positioning adaptive clamping device is located to the side of the panel adaptive clamping device and the web adaptive clamping lifting platform.

[0007] The panel adaptive clamping device includes a first transverse clamping screw transmission platform, a first longitudinal clamping screw transmission slide mounted on the first transverse clamping screw transmission platform and extending upward, and a first clamping claw mounted on the first longitudinal clamping screw transmission slide. The first transverse clamping screw transmission platform is fixed inside the equipment housing. The first transverse clamping screw transmission platform drives the first longitudinal clamping screw transmission slide to move closer to or further away from the web adaptive clamping lifting platform. The first longitudinal clamping screw transmission slide drives the first clamping claw to move up and down.

[0008] The web plate adaptive clamping lifting platform includes a second transverse clamping screw transmission platform, a movable lifting platform installed on the second transverse clamping screw transmission platform, a positioning plate installed on the top of the movable lifting platform, a second longitudinal clamping screw transmission slide installed on the movable lifting platform and extending upward, and a second clamping claw installed on the second longitudinal clamping screw transmission slide. The second transverse clamping screw transmission platform is fixed inside the equipment box. The movable lifting platform drives the positioning plate to rise and fall relative to the equipment box. The second longitudinal clamping screw transmission slide drives the second clamping claw (13) to rise and fall relative to the positioning plate.

[0009] The profile positioning adaptive clamping device includes a transverse positioning clamping screw drive slide, a drive platform installed on the transverse positioning clamping screw drive slide, and a clamping block fixed to the inner side of the drive platform. The transverse positioning clamping screw drive slide is fixed inside the equipment housing. The transverse positioning clamping screw drive slide drives the drive platform to move closer to or away from the panel adaptive clamping device and the web adaptive clamping lifting platform.

[0010] Preferably, it further includes a clamping baffle, which is fixed on the slider of the first transverse clamping screw transmission platform and located below the first clamping claw.

[0011] Preferably, a positioning block is provided on the working surface of the equipment housing; the positioning block and the profile positioning adaptive clamping device are arranged opposite to each other, and the positioning block and the profile positioning adaptive clamping device are respectively located on both sides of the panel adaptive clamping device and the web adaptive clamping lifting platform.

[0012] Preferably, the housing has slots above the first transverse clamping screw transmission platform, the second transverse clamping screw transmission platform, and the transverse positioning clamping screw transmission slide. The sliding blocks on the first transverse clamping screw transmission platform and the transverse positioning clamping screw transmission slide move within the corresponding slot range. The moving lifting platform moves through the corresponding slots when it is raised or lowered. The first longitudinal clamping screw transmission slide, the second longitudinal clamping screw transmission slide, and the transmission platform are all located above the housing.

[0013] Preferably, the clamping block is L-shaped.

[0014] Preferably, the transmission distance of the first longitudinal clamping screw drive slide is twice that of the second longitudinal clamping screw drive slide.

[0015] Preferably, the first transverse clamping screw drive platform, the second transverse clamping screw drive platform, the first longitudinal clamping screw drive slide, the second longitudinal clamping screw drive slide, and the transverse clamping screw drive slide are electric screw slides.

[0016] Preferably, a displacement sensor is provided at the clamping baffle, a pressure sensor and a displacement sensor are installed on one side of the worktable of the second transverse clamping screw transmission platform, a displacement sensor is provided on one side of the worktable of the movable lifting platform, and a pressure sensor is provided on one side of the worktable of the first longitudinal clamping screw transmission slide, the second longitudinal clamping screw transmission slide, and the transverse clamping screw transmission slide.

[0017] A method of using an adaptive T-profile welding clamping device includes the following steps: the adaptive clamping device of the panel first works, then the adaptive clamping lifting platform of the web plate works, and finally the adaptive clamping device of the profile positioning works.

[0018] When a T-profile needs to be welded, the displacement sensor installed at the clamping baffle automatically detects the position of the T-profile panel and contacts the clamping baffle with the panel. At this time, the slider of the first longitudinal clamping screw drive slide works and the first clamping claw presses down. When the pressure sensor senses that the pressure exceeds the preset range, the first clamping claw stops pressing down.

[0019] The second transverse clamping screw drive platform operates after the panel adaptive clamping device has finished working. A displacement sensor mounted on the platform senses the panel's position and moves to a position 0.1–0.3 meters from the panel, waiting 5–6 seconds. The moving lifting platform rises, and a displacement sensor on it monitors the web plate's position. The platform stops rising when the positioning plate contacts the web plate. After the waiting time, the pressure sensor in the second transverse clamping screw drive platform activates, moving the slider to drive the positioning plate to work again. The positioning plate begins to approach the panel and gradually presses it down. When the pressure sensor detects that the pressure exceeds a preset range, the first transverse clamping screw drive platform stops working. At this time, the second longitudinal clamping screw drive slide begins working, and the clamping jaws press down. When the pressure sensor detects that the pressure exceeds a preset range, the clamping jaws stop pressing down.

[0020] The transverse clamping screw drive slide begins to operate after the panel adaptive clamping device and the web adaptive clamping lifting platform in the T-profile welding clamping device have both completed their operations. At this time, the transverse clamping screw drive slide begins to move, and the clamping block begins to press the T-profile panel and web. When the pressure sensor on the transverse clamping screw drive slide worktable senses that the pressure exceeds the preset range, the clamping block stops working.

[0021] Preferably, the pressure sensor has a preset range of 0.2 to 0.3 MPa.

[0022] Beneficial effects: The adaptive T-profile welding clamping device proposed in this invention can simultaneously process two types of welding clamping equipment: ordinary T-profiles and panel-bent T-profiles. The baffle has a spherical surface on the side that contacts the panel, so that regardless of whether the T-profile is curved or straight, it can effectively contact the worktable and be fixed by the panel. This reduces the scheduling cost of T-profiles while improving the welding efficiency of T-profiles. Attached Figure Description

[0033] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. After reading this invention, any modifications of the invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0034] This invention provides an adaptive T-profile welding clamping device, taking a 2-meter-long bent T-profile as an example.

[0035] like Figure 1 , Figure 2 As shown, the adaptive T-profile welding clamping device includes an equipment housing 1, a panel adaptive clamping device 2, a web adaptive clamping lifting platform 3, a profile positioning adaptive clamping device 4, and a positioning block 5.

[0036] The equipment enclosure 1 encloses the entire equipment, providing protection for the core components and support for the parts.

[0037] like Figure 3 As shown, the panel adaptive clamping device 2 includes a first transverse clamping screw transmission platform 6, a first longitudinal clamping screw transmission slide 7, and a first clamping claw 8.

[0038] The first transverse clamping screw transmission platform 6 is fixed inside the equipment housing 1 by a threaded connection. The first longitudinal clamping screw transmission slide 7 is fixed above the workbench of the first transverse clamping screw transmission platform 6 near the T-shaped panel by welding. The first clamping claw 8 is fixed on the first longitudinal clamping screw transmission slide 7 by a threaded connection.

[0039] like Figure 4As shown, the web plate adaptive clamping lifting platform 3 includes a second transverse clamping screw transmission platform 10, a movable lifting platform 11, a positioning plate 12, clamping claws 13, and a second longitudinal clamping screw transmission slide 14.

[0040] The second transverse clamping screw transmission platform is fixed inside the equipment housing by a threaded connection. The movable lifting platform 11 is fixed on the workbench of the second transverse clamping screw transmission platform 10 by a threaded connection. The positioning plate is welded onto the movable lifting platform 11. The second longitudinal clamping screw transmission slide 10 is fixed at the middle position of the side of the positioning plate 12 facing the web of the T-profile by a threaded connection. The clamping claw 13 is fixed on the second slider 19 of the longitudinal clamping transmission slide 14 by a threaded connection.

[0041] like Figure 5 As shown, the profile positioning adaptive clamping device 4 includes a transverse positioning clamping screw drive slide 15, a drive table 16, and a clamping block 17.

[0042] The transverse positioning clamping screw drive slide 15 is fixed inside the equipment housing by a threaded connection, the drive table 16 is fixed on the first slider 18 of the transverse positioning clamping screw drive slide 15 by a threaded connection, and the clamping block 17 is fixed in the middle position of the drive table 16 by a threaded connection.

[0043] like Figure 10 As shown, the clamping block 5 is fixed to the working surface of the equipment housing by a threaded connection, and is used to position the T-profile in a fixed position to achieve subsequent clamping and welding of the equipment.

[0044] like Figure 3 As shown, the clamping baffle 9 is fixed to the slider of the transverse clamping screw transmission platform 6 by a threaded connection. The baffle has a spherical surface on the side that contacts the panel, so that the T-profile can effectively contact the worktable and be fixed by the panel, regardless of whether the T-profile is curved or straight.

[0045] like Figure 4 , Figure 9 As shown, the clamping claw 13 is fixed to the second slider 19 of the second longitudinal clamping screw drive slide 14 by a threaded connection, and a boss is provided at the connection between the clamping claw 13 and the second slider 19, which provides longitudinal clamping force to the web of the T-profile during the clamping process and also plays a clamping role in the lateral direction.

[0046] like Figure 5 , 10 As shown, the clamping block 17 is designed in an L shape, which serves both as a positioning function and as a way to prevent interference from the welding equipment during the welding process, i.e., to avoid accidentally welding the clamping block to the T-profile together.

[0047] The first transverse clamping screw transmission platform 6 has 3 units, the first longitudinal clamping screw transmission slide 7 has 3 units, and the first clamping claw 8 has 3 units; the second transverse clamping screw transmission platform 10 has 2 units, the movable lifting platform 11 has 2 units, the second longitudinal clamping screw transmission slide 14 has 2 units, and the clamping claw 13 has 2 units.

[0048] The first transverse clamping screw drive platform 6, the second transverse clamping screw drive platform 10, the first longitudinal clamping screw drive slide 7, the second longitudinal clamping screw drive slide 14, and the transverse clamping screw drive slide 15 belong to the same type of slide.

[0049] like Figure 6 , Figure 7 As shown, the transmission distances of the first longitudinal clamping screw drive slide 7 and the second longitudinal clamping screw drive slide 14 are different. The transmission distance of the first longitudinal clamping screw drive slide 7 is twice that of the second longitudinal clamping screw drive slide 14.

[0050] The first transverse clamping screw drive platform 6, the second transverse clamping screw drive platform 10, the first longitudinal clamping screw drive slide 7, the second longitudinal clamping screw drive slide 14, and the transverse clamping screw drive slide 15 are all electric screw slides.

[0051] In the T-profile welding clamping device, the panel adaptive clamping device 2 works first, followed by the web adaptive clamping lifting platform 3, and finally the profile positioning adaptive clamping device 4.

[0052] Displacement sensors are installed at the clamping baffle 9. Pressure sensors and displacement sensors are installed on one side of the worktable of the second transverse clamping screw transmission platform 10. Displacement sensors are installed on one side of the worktable of the movable lifting platform 11. Pressure sensors are installed on one side of the worktable of the first longitudinal clamping screw transmission slide 7, the second longitudinal clamping screw transmission slide 14, and the transverse clamping screw transmission slide 15.

[0053] When a T-profile needs to be welded, the displacement sensor installed at the clamping baffle automatically detects the position of the T-profile panel and brings the clamping baffle 9 into contact with the panel. At this time, the slider of the first longitudinal clamping screw drive slide 7 works, and the first clamping claw 8 presses down. When the pressure sensor senses that the pressure exceeds 0.2 MPa, the first clamping claw 8 stops pressing down.

[0054] The second transverse clamping screw drive platform 10 starts working after the panel adaptive clamping device 2 finishes its operation. At this time, the displacement sensor installed on the worktable of the second transverse clamping screw drive platform 10 senses the position of the panel and moves to 0.1 meters from that position, waiting for 6 seconds. Then, the moving lifting platform 11 rises. At this time, the displacement sensor on the moving lifting platform 11 monitors the position of the web plate. When the positioning plate 12 on the moving lifting platform contacts the web plate, the rising stops. After the waiting time ends, the pressure sensor in the second transverse clamping screw drive platform 10 starts working. At this time, the slider of the second transverse clamping screw drive platform 10 drives the positioning plate 12 to work again. The positioning plate 12 begins to approach the panel and gradually presses the panel. When the pressure sensor senses that the pressure exceeds 0.2 MPa, the second transverse clamping screw drive platform 10 stops working. At this time, the second longitudinal clamping screw drive slide 14 starts working, and the clamping jaw 13 presses down. When the pressure sensor senses that the pressure exceeds 0.2 MPa, the clamping jaw 13 stops pressing down.

[0055] The transverse clamping screw drive slide 15 starts working after the panel adaptive clamping device 2 and the web adaptive clamping lifting platform 3 in the T-profile welding clamping device have finished working. At this time, the transverse clamping screw drive slide 15 starts to move, and the clamping block 17 starts to press the T-profile panel and web. When the pressure sensor on the worktable of the transverse clamping screw drive slide 15 senses that the pressure exceeds 0.2 MPa, the clamping block 17 stops working.

[0056] In the T-profile welding clamping device, the initial position of the self-adaptive clamping device 2 is at the furthest point from the T-profile panel placement position; the initial position of the slider of the longitudinal clamping screw drive slide 1 in the T-profile panel self-adaptive clamping device 2 is at the furthest point from the equipment box workbench.

[0057] The initial position of the web self-adaptive clamping lifting platform 3 is at the furthest point from the placement position of the T-section web; the movable lifting platform 11 in the web self-adaptive clamping lifting platform 3, such as Figure 8 As shown, the initial lifting value is set to 0; the slider of the second longitudinal clamping screw drive slide 14 in the web self-adaptive clamping lifting platform 3 is initially positioned at the position farthest from the positioning plate.

[0058] The initial position of the profile positioning adaptive clamping device 4 is at the furthest distance from the placement position of the T-profile panel and web.
