Abstract

The present invention relates to the technical field of thin plate welding, and particularly to a ship thin plate welding device with a compensation and leveling function. The technical problems to be solved are as follows: the edge limit support for the weld of the thin plate is not sufficient, the suppression effect on the thermal deformation of the thin plate is poor, and the position of the welding torch is relatively fixed, which is not convenient for forming temperature compensation for the surrounding area of the welding position. A ship thin plate welding device with a compensation and leveling function includes: a bottom plate, etc.; two brackets, both fixedly connected to the bottom plate, and a thin plate body is placed on each of the two brackets. The limiting strip and the pressing strip jointly clamp and support the thin plate body. When the thin plate body has slight deformation, the limiting strip and the pressing strip jointly squeeze the thin plate body, which can level the thin plate body, make the welding edges of the two thin plate bodies straighter, and thus better weld the thin plate body.

Description

Technical Field

[0001] The present invention relates to the technical field of thin plate welding, and particularly relates to a ship thin plate welding device with a compensation and leveling function. Background Art

[0002] For the purpose of reducing the weight of the ship and the production cost of the ship, a relatively large number of thin plates with a thickness less than or equal to 6 mm are used in the hull structure and the superstructure on the ship. When the size of the thin plate is insufficient, usually two or more thin plates need to be welded together. The existing thin plate welding devices have the following problems:

[0003] 1. Due to local overheating, the welding edges of the thin plates are prone to thermal deformation. The fixture structure of the existing thin plate welding device is relatively simple, the limit support for the weld edges of the thin plates is not sufficient, and the suppression effect on the thermal deformation of the thin plates is poor;

[0004] 2. The position of the welding torch of the existing thin plate welding device is relatively fixed, which is not convenient for forming temperature compensation for the surrounding area of the welding position, and local overheating of the thin plate is likely to occur, which may cause large thermal deformation of the thin plate and affect the welding quality. Summary of the Invention

[0005] In order to overcome the above-mentioned drawbacks, the present invention provides a ship thin plate welding device with a compensation and leveling function, which can more fully limit and support the weld edges of the thin plates and is convenient for adjusting the position of the welding torch to form temperature compensation for the surrounding area of the welding position, thereby reducing the thermal deformation of the thin plates.

[0006] The technical solution of the present invention is: a ship thin plate welding device with a compensation and leveling function, including:

[0007] A bottom plate;

[0008] Two brackets, both fixedly connected to the bottom plate, and thin plate bodies are placed on both brackets;

[0010] Two light-shielding transparent plates, both fixedly connected to the main bracket;

[0011] A clamping and leveling assembly, arranged on the main bracket;

[0012] A welding assembly, arranged on the clamping and leveling assembly;

[0013] A rolling limit assembly is arranged on the main bracket, and the rolling limit assembly is connected to the welding assembly.

[0014] In one embodiment, the clamping and leveling assembly includes: a set of hydraulic rods are fixedly connected to both sides of the through groove of the main bracket, and the number of the two sets of hydraulic rods is two; a lifting frame is fixedly connected between the telescopic rods of each set of two hydraulic rods; a lower pressing strip is fixedly connected to the lower part of the lifting frame; two limiting strips are respectively fixedly connected to one side of the two brackets close to each other.

[0015] In one embodiment, the welding assembly includes: an upper slide rail is fixedly connected between the two lifting frames; an upper electric slider is slidably connected to the upper slide rail; two guiding strips are both fixedly connected to the lower side surface of the upper electric slider; a mounting bracket is slidably connected between the two guiding strips; a welding gun is fixedly connected to the lower part of the mounting bracket.

[0016] In one embodiment, the rolling and limiting assembly includes: a lower slide rail is fixedly connected to the lower part of the main bracket; a lower electric slider is slidably connected to the lower slide rail; a support frame is fixedly connected to one side of the upper electric slider and the lower electric slider close to each other, and the two support frames are symmetrically arranged; three rollers are rotatably connected to one end of the two support frames close to each other.

[0017] In one embodiment, there is also a moving assembly. The moving assembly is arranged on the support frame located above, the moving assembly is connected to the mounting bracket, and the moving assembly is used to slightly move the welding gun. The moving assembly includes: a guiding grooved wheel frame is rotatably connected to the support frame above, and a wavy guiding groove connected end to end is formed on the guiding grooved wheel frame; a transmission rod frame is fixedly connected to the mounting bracket, and one end of the transmission rod frame is located in the wavy guiding groove on the guiding grooved wheel frame; a pulley group is arranged between the roller closest to the guiding grooved wheel frame and the guiding grooved wheel frame. The pulley group includes a large pulley, a small pulley and a transmission belt. The large pulley is fixedly connected to the roller closest to the guiding grooved wheel frame, the small pulley is fixedly connected to the guiding grooved wheel frame, and the transmission belt is wound between the large pulley and the small pulley.

[0018] In one embodiment, there is also: a flame preheating component is fixedly connected to the upper side surface of the lower electric slider, and the flame preheating component is located on the side of the support frame away from the welding gun.

[0019] In one embodiment, there is also an adsorption assembly. The adsorption assembly is arranged on the bracket, and the adsorption assembly is used to adsorb the thin plate body. The adsorption assembly includes: four air storage cylinders are fixedly connected to the bottom plate; two transmission frames are fixedly connected to the lower part of the two lifting frames; the bottom ends of the four transmission frames are all fixedly connected with partition plates, and the partition plates are slidably connected with the air storage cylinders; two mounting plates are fixedly connected to the upper part of the two brackets; a number of rubber blocks are fixedly connected to the two mounting plates; a pipe rack is fixedly connected to the two mounting plates, and two communication ports are arranged on the two pipe racks. The communication ports on the pipe rack are located above the partition plate, and the pipe rack and the two air storage cylinders on the same side of the main bracket are communicated; a number of suction cups are arranged on the two pipe racks, and the number of suction cups are all communicated with the pipe rack.

[0020] In one of the embodiments, it further includes: two protective plates, respectively fixedly connected to one side of the two support frames close to the welding gun.

[0021] Beneficial effects: 1. The limiting strip and the pressing strip jointly clamp and support the thin plate body. When the thin plate body has slight deformation, the limiting strip and the pressing strip jointly squeeze the thin plate body, which can level the thin plate body, making the welding edges of the two thin plate bodies straighter, so as to better weld the thin plate body. Then, the upper roller and the lower roller respectively roll the upper side and the lower side of the welding edges of the two thin plate bodies, so as to more fully clamp and support the welding edges of the two thin plate bodies. Then, the welding gun welds the two thin plate bodies. In this way, the limiting strip and the pressing strip jointly clamp and limit the two sides of the welding edges of the two thin plate bodies, so as to inhibit the deformation of the thin plate body during the welding process. The upper roller and the lower roller jointly clamp and limit a part of the welding edges of the two thin plate bodies, so as to further inhibit the deformation of the thin plate body during the welding process, making the weld more straight, and thus improving the welding effect.

[0022] 2. The upper roller rolls the upper side of the welding edges of the two thin plate bodies. The thin plate body drives the roller to rotate through friction. The rotation of one roller drives the guide groove wheel frame to rotate through a pulley group. The guide groove wheel frame squeezes the transmission rod frame, the mounting bracket and the welding gun to move slightly back and forth in the direction perpendicular to the welding edges of the two thin plate bodies. In this way, the welding gun moves along a wavy path, so as to increase the heating range for adjusting the welding position, form temperature compensation for the surrounding area of the welding position, and thus can reduce the deformation of the thin plate body caused by local overheating. In this way, the welding effect on the thin plate body is further improved.

[0023] 3. The telescopic rod of the hydraulic rod extends to drive the lifting frame, the pressing strip, the transmission frame and the partition plate to move downward. A negative pressure is formed in the cavity above the partition plate in the suction cup, the pipe rack and the air storage cylinder. The suction cup adsorbs the thin plate body. The rubber block hinders the sliding of the thin plate body through friction. Then, the pressing strip contacts the upper side of the thin plate body. The limiting strip and the pressing strip jointly clamp and support the thin plate body, so as to reduce the offset caused by the extrusion of the pressing strip on the thin plate body, and thus weld the thin plate body more accurately.

Detailed implementation manners

[0034] The present invention will be further described below with reference to the embodiments shown in the drawings.

[0035] Embodiment 1: A ship thin plate welding device with a compensation and leveling function, as Figures 1-9 shown, includes:

[0036] Bottom plate 1;

[0037] Two brackets 2, both connected to the bottom plate 1 by bolts, and the thin plate body 5 is placed on both of the two brackets 2;

[0038] Main support 3, connected to the bottom plate 1 by bolts, and a through groove is opened in the upper part of the main support 3;

[0039] The two light-shielding transparent plates 4 are both connected to the main bracket 3 by bolts;

[0040] The clamping and leveling assembly is arranged on the main bracket 3 and is used for clamping and leveling the thin plate body 5;

[0041] The welding assembly is arranged on the clamping and leveling assembly and is used for welding the thin plate body 5;

[0042] The rolling and limiting assembly is arranged on the main bracket 3, the rolling and limiting assembly is connected to the welding assembly, and the rolling and limiting assembly is used for rolling the thin plate body 5.

[0043] The clamping and leveling assembly includes: A set of hydraulic rods 61 are connected to both sides of the through groove of the main bracket 3 by bolts, and the number of the two sets of hydraulic rods 61 is two; A lifting frame 62 is connected between the telescopic rods of each set of two hydraulic rods 61 by bolts; The lower pressing strip 63 is welded to the lower part of the lifting frame 62; The two limiting strips 64 are respectively welded to one side of the two brackets 2 close to each other.

[0044] The welding assembly includes: The upper slide rail 71 is connected between the two lifting frames 62 by bolts; The upper electric slider 72 is slidably connected to the upper slide rail 71; The two guiding strips 73 are both welded to the lower side surface of the upper electric slider 72; The mounting bracket 74 is slidably connected between the two guiding strips 73; The welding gun 75 is connected to the lower part of the mounting bracket 74 by bolts.

[0045] The rolling and limiting assembly includes: The lower slide rail 81 is connected to the lower part of the main bracket 3 by bolts; The lower electric slider 82 is slidably connected to the lower slide rail 81; Support frames 83 are welded to one side of the upper electric slider 72 and the lower electric slider 82 close to each other, and the two support frames 83 are symmetrically arranged; Three rollers 84 are rotatably connected to one end of the two support frames 83 close to each other.

[0046] The worker places the two thin plate bodies 5 to be welded on two brackets 2 respectively, such that the welding edges of the two thin plate bodies 5 are located between the two limiting bars 64, and the welding edges of the two thin plate bodies 5 are aligned with the welding gun 75. The worker activates the hydraulic rod 61, and the telescopic rod of the hydraulic rod 61 extends to drive the lifting frame 62, the lower pressing strip 63, the upper slide rail 71, the upper electric slider 72, the guiding strip 73, the mounting bracket 74, and the welding gun 75 to move downward. The lower pressing strip 63 contacts the upper side of the thin plate body 5, and the limiting bar 64 and the lower pressing strip 63 jointly clamp and support the thin plate body 5. When the thin plate body 5 has slight deformation, the limiting bar 64 and the lower pressing strip 63 jointly squeeze the thin plate body 5, which can level the thin plate body 5, making the welding edges of the two thin plate bodies 5 straighter, so as to better weld the thin plate body 5. Then the worker activates the upper electric slider 72 and the lower electric slider 82. The upper electric slider 72 and the lower electric slider 82 move synchronously along the upper slide rail 71 and the lower slide rail 81 respectively. The upper electric slider 72 drives the guiding strip 73, the mounting bracket 74, the welding gun 75, the upper support frame 83, and the upper roller 84 to move along the upper slide rail 71, and the lower electric slider 82 drives the lower support frame 83 and the lower roller 84 to move along the lower slide rail 81. The upper roller 84 and the lower roller 84 respectively roll-press the upper side and the lower side of the welding edges of the two thin plate bodies 5, so as to more fully clamp and support the welding edges of the two thin plate bodies 5. When the lower end of the welding gun 75 is located above the welding edges of the two thin plate bodies 5, the worker activates the welding gun 75, and the upper electric slider 72 and the lower electric slider 82 continue to move. The welding gun 75 welds the two thin plate bodies 5. In this way, the limiting bar 64 and the lower pressing strip 63 jointly clamp and limit the two sides of the welding edges of the two thin plate bodies 5, thereby suppressing the deformation of the thin plate body 5 during the welding process. The upper roller 84 and the lower roller 84 jointly clamp and limit a part of the welding edges of the two thin plate bodies 5, thereby further suppressing the deformation of the thin plate body 5 during the welding process, making the weld seam straighter, and thus improving the welding effect. Then when the welding gun 75 moves to no longer be located above the welding edges of the two thin plate bodies 5, the welding gun 75 completes the welding of the two thin plate bodies 5. Then the worker turns off the welding gun 75. After the weld seams of the two thin plate bodies 5 are cooled, the worker controls the telescopic rod of the hydraulic rod 61 to contract to drive the lifting frame 62, the lower pressing strip 63, the upper slide rail 71, the upper electric slider 72, the guiding strip 73, the mounting bracket 74, and the welding gun 75 to move upward and reset. The limiting bar 64 and the lower pressing strip 63 no longer clamp the thin plate body 5. The worker pulls out the two thin plate bodies 5 from one side of the main bracket 3. Then the worker controls the upper electric slider 72 and the lower electric slider 82 to move in the reverse direction and reset. The upper electric slider 72 drives the guiding strip 73, the mounting bracket 74, and the welding gun 75 to move and reset along the direction of the upper slide rail 71.The lower electric slider 82 drives the lower support frame 83 and the lower roller 84 to move reversely along the lower slide rail 81 for resetting.

[0047] Embodiment 2: On the basis of Embodiment 1, as Figures 5-7 shown, it further includes a moving component. The moving component is arranged on the upper support frame 83. The moving component is connected to the mounting bracket 74. The moving component is used for slightly moving the welding gun 75. The moving component includes: a guiding grooved wheel frame 91, rotatably connected to the upper support frame 83. A wavy guiding groove that is connected end to end is formed on the guiding grooved wheel frame 91; a transmission rod frame 92, welded to the mounting bracket 74. One end of the transmission rod frame 92 is located in the wavy guiding groove on the guiding grooved wheel frame 91; a pulley group 93 is arranged between the roller 84 closest to the guiding grooved wheel frame 91 and the guiding grooved wheel frame 91. The pulley group 93 includes a large pulley, a small pulley and a transmission belt. The large pulley is connected to the roller 84 closest to the guiding grooved wheel frame 91 through a flat key. The small pulley is connected to the guiding grooved wheel frame 91 through a flat key. The transmission belt is wound between the large pulley and the small pulley.

[0048] The upper electric slider 72 drives the guiding strip 73, the mounting bracket 74, the welding gun 75, the upper support frame 83 and the upper roller 84 to move along the upper slide rail 71. The upper roller 84 rolls the upper side of the welding edges of the two thin plate bodies 5. The thin plate body 5 drives the roller 84 to rotate through friction. The rotation of one of the rollers 84 drives the guiding grooved wheel frame 91 to rotate through the pulley group 93. The guiding grooved wheel frame 91 squeezes the transmission rod frame 92, the mounting bracket 74 and the welding gun 75 to move slightly back and forth in the direction perpendicular to the welding edges of the two thin plate bodies 5. Thus, the welding gun 75 moves along a wavy path, thereby increasing the heat receiving range for adjusting the welding position, forming temperature compensation for the surrounding area of the welding position, and further reducing the deformation of the thin plate body 5 caused by local overheating. Thus, the welding effect on the thin plate body 5 is improved.

[0049] Embodiment 3: On the basis of Embodiment 2, as Figure 5 and Figure 6 shown, it further includes: a flame preheating component 901, connected to the upper side of the lower electric slider 82 through bolts. The flame preheating component 901 is located on the side of the support frame 83 away from the welding gun 75.

[0050] The upper electric slider 72 and the lower electric slider 82 move synchronously along the upper slide rail 71 and the lower slide rail 81 respectively. The lower electric slider 82 drives the lower support frame 83, the lower roller 84 and the flame preheating component 901 to move along the lower slide rail 81. When the flame preheating component 901 is located below the welding edges of the two thin plate bodies 5, the worker starts the flame preheating component 901, and the flame preheating component 901 preheats the lower sides of the welding edges of the two thin plate bodies 5, and then the welding gun 75 welds the two thin plate bodies 5, so as to reduce the local temperature difference during welding, and further reduce the thermal deformation of the thin plate body 5.

[0051] Embodiment 4: On the basis of Embodiment 3, as Figure 2 , Figure 3 , Figure 8 and Figure 9 shown, it further includes an adsorption component. The adsorption component is arranged on the bracket 2 and is used for adsorbing the thin plate body 5. The adsorption component includes: four air storage cylinders 101, welded on the bottom plate 1; two lower parts of the lifting frames 62 are both welded with two transmission frames 102; the bottom ends of the four transmission frames 102 are both welded with partition plates 103, and the partition plates 103 are slidably connected with the air storage cylinders 101; the upper parts of the two brackets 2 are both connected with mounting plates 104 by bolts; a plurality of rubber blocks 105 are fixedly connected to the two mounting plates 104; pipe racks 106 are welded on the two mounting plates 104, and two communication ports are arranged on the two pipe racks 106. The communication ports on the pipe racks 106 are located above the partition plates 103. The pipe racks 106 and the two air storage cylinders 101 on the same side of the main bracket 3 are communicated; a plurality of suction cups 107 are arranged on the two pipe racks 106, and the plurality of suction cups 107 are all communicated with the pipe racks 106.

[0052] The worker places the two thin plate bodies 5 to be welded on two brackets 2 respectively. The lower side of the thin plate body 5 contacts the suction cup 107, and the lower side of the thin plate body 5 contacts the rubber block 105. The telescopic rod of the hydraulic rod 61 extends to drive the lifting frame 62, the lower pressing strip 63, the transmission frame 102, the partition plate 103, the upper slide rail 71, the upper electric slider 72, the guiding strip 73, the mounting bracket 74 and the welding gun 75 to move downward. The cavity above the partition plate 103 in the air storage cylinder 101 increases, and a negative pressure is formed in the cavity above the partition plate 103 in the suction cup 107, the pipe rack 106 and the air storage cylinder 101. The suction cup 107 adsorbs the thin plate body 5, and the rubber block 105 hinders the sliding of the thin plate body 5 through friction. Then the lower pressing strip 63 contacts the upper side of the thin plate body 5, and the limiting strip 64 and the lower pressing strip 63 jointly clamp and support the thin plate body 5, so as to reduce the deviation caused by the extrusion of the lower pressing strip 63 on the thin plate body 5, and then weld the thin plate body 5 more accurately. When the telescopic rod of the hydraulic rod 61 extends to drive the lifting frame 62, the lower pressing strip 63, the transmission frame 102, the partition plate 103, the upper slide rail 71, the upper electric slider 72, the guiding strip 73, the mounting bracket 74 and the welding gun 75 to move upward and reset, the suction cup 107 no longer adsorbs the thin plate body 5.

[0053] Embodiment 5: On the basis of Embodiment 4, as Figure 5 and Figure 6 shown, it further includes: two protective plates 11, which are respectively welded to one side of the two support frames 83 close to the welding gun 75.

[0054] When the welding gun 75 welds the two thin plate bodies 5, the protective plates 11 can block the spatter generated by welding, thereby reducing the metal adhesion on the rollers 84.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
