Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to an auxiliary device for thick plate welding. Background Art

[0002] Welding is a manufacturing process that joins metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. In the process of offshore engineering, large pressure vessel and large container ship manufacturing, due to the need to use thicker plates to build the outer layer and its stressed parts, more and more thick steel plates are used for welding.

[0003] When welding thick plates, double-sided welding is required to increase the welding firmness; when two thick plates are placed flat on the welding platform, after one side of the thick plate is welded, the thick plate needs to be flipped. However, due to factors such as stress at the connection of the two thick plates, it is easy to break when the thick plate is flipped, and the two thick plates are relatively heavy and not easy to flip; if the two thick plates need to be welded at a specific angle, the welding operator needs to flip one of the thick plates upward and tilt it at a specific angle, which is relatively troublesome to operate and the flipping angle is not easy to control.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. In the drawings or descriptions, similar or identical parts are denoted by the same reference numerals, and in actual applications, the shapes, thicknesses or heights of the components may be enlarged or reduced. The embodiments listed in the present invention are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Any obvious modification or change made to the present invention does not depart from the spirit and scope of the present invention.

[0023] In one embodiment, as Figure 1 and Figure 2 shown, a thick plate welding auxiliary device includes an auxiliary support part 100, a belt conveying part 200 and a state adjusting mechanism 300. There are two belt conveying parts 200, and the two belt conveying parts 200 are respectively arranged on both sides of the state adjusting mechanism 300. The state adjusting mechanism 300 is arranged on the auxiliary support part 100, and the two belt conveying parts 200 are used to convey the thick plate to be welded to the state adjusting mechanism 300. The state adjusting mechanism 300 includes a side turning support assembly 400, an upper turning support assembly 500, side fixing plates 600, a side turning motor 700 and an angle adjusting driving assembly 900. There are two side fixing plates 600, and the two side fixing plates 600 are respectively rotatably connected to the two ends of the side turning support assembly 400. The side fixing plates 600 are connected to the corresponding auxiliary support part 100, and a side turning motor 700 for driving the side turning support assembly 400 to rotate is arranged on the side fixing plates 600. The rotation center line of the side turning support assembly 400 is parallel to the moving direction of the thick plate to be welded on the belt conveying part 200. There are two upper turning support assemblies 500, and the two upper turning support assemblies 500 are rotatably arranged at the two ends of the side turning support assembly 400 in a symmetric manner. The rotation center line of the upper turning support assembly 500 is parallel to the width direction of the belt conveying part 200, and the thick plate to be welded is conveyed on the belt conveying part 200 and placed on the corresponding upper turning support assembly 500. The angle adjusting driving assembly 900 is arranged on the side turning support assembly 400 and is connected to both upper turning support assemblies 500. The angle adjusting driving assembly 900 can drive the two upper turning support assemblies 500 to rotate synchronously and in opposite directions. Side clamping parts 550 are arranged on the same side of the two upper turning support assemblies 500. When the side turning support assembly 400 is inclined, the side clamping parts 550 can lift the side of the thick plate to be welded and press the thick plate. In an embodiment of the present invention, two thick plates to be welded are respectively placed on two belt conveying parts 200, and the welding edges of the two thick plates are in a relative state; the two belt conveying parts 200 work synchronously and convey the two thick plates towards the two upper turning and supporting components 500; when the front ends of the thick plates are on the corresponding upper turning and supporting components 500 and the front ends of the two thick plates are in contact, the belt conveying parts 200 stop working; if the two thick plates are welded horizontally, the welding operator welds the contact parts at the front ends of the two thick plates together from the upper side; if the two thick plates need to be welded at an angle, the angle adjusting drive assembly 900 drives the two upper turning and supporting components 500 to rotate synchronously and in opposite directions, and the opposite ends of the two upper turning and supporting components 500 rotate downward, so that the two thick plates rotate with the upper turning and supporting components 500 and form an angle. At this time, the welding operator welds the contact parts at the front ends of the two thick plates together from the upper surface; after the welding on the upper surface of the thick plate is completed, the side turning motor 700 drives the side turning support assembly 400 to rotate and the side turning support assembly 400 rotates downward towards the side clamping part 550, so that the two welded thick plates slide laterally along the upper turning and supporting components 500 until the upper turning and supporting components 500 and the thick plates are in a vertical state, and the side of the thick plate is lifted by the side clamping part 550 and the side clamping part 550 presses the thick plate tightly to prevent the thick plate from detaching from the upper turning and supporting components 500; then the welding operator can weld the two thick plates from the non-welded side of the thick plate. Since the thick plate is in a vertical state, it is convenient for welding operation and double-sided welding to ensure the welding firmness; after welding is completed, the side turning motor 700 drives the side turning support assembly 400 to rotate in the reverse direction and makes the side where the side clamping part 550 is located tilt upward, so that the welded thick plate automatically slides out from the side of the upper turning and supporting components 500 away from the side clamping part 550, and automatic blanking can be carried out; after blanking is completed, the angle adjusting drive assembly 900 and the side turning motor 700 drive the side turning support assembly 400 and the upper turning and supporting components 500 to return to the initial horizontal state.

[0024] In one embodiment, as Figures 1-5As shown, the upper steering support assembly 500 includes an upper support frame 510 and an upper steering shaft 530. Both ends of the upper steering shaft 530 are mounted on the side steering support assembly 400 through rotating seats, and the upper steering shaft 530 is connected to the angle adjustment drive assembly 900. The angle adjustment drive assembly 900 can drive the upper steering shaft 530 to rotate; both sides of the upper support frame 510 are fixed on the upper steering shaft 530, and a plurality of support rollers 520 arranged side by side are provided inside the upper support frame 510. The ends of the support rollers 520 are rotatably connected to the inner wall of the upper support frame 510. The side clamping portion 550 is provided on one side edge of the upper support frame 510; in the implementation of the present invention, the front end of the thick plate is on the upper support frame 510 and is rolled up by the support rollers 520. When the angle adjustment drive assembly 900 drives the upper steering shaft 530 to rotate, the upper steering shaft 530 drives the upper support frame 510 to tilt. When the upper support frame 510 tilts, the thick plate moves towards the end of the upper support frame 510 that tilts downward under the drive of its own gravity.

[0025] In one embodiment, as Figures 1-5 shown, when the upper steering support assembly 500 is in a horizontal state, the arc top of the support roller 520 is on the same horizontal plane as the upper surface of the belt conveying portion 200 to ensure that the thick plate moves from the belt conveying portion 200 to the upper steering support assembly 500 without hindrance.

[0026] In one embodiment, as Figures 1-5 shown, a lower steering gear 540 is provided on the upper steering shaft 530, and at least one adjustment motor 950 is provided on the side steering support assembly 400. The angle adjustment drive assembly 900 includes a left - right hand adjustment screw rod 910, a guide rod 940, and two adjustment sliders 920. The left - right hand adjustment screw rod 910 is rotatably provided on the side steering support assembly 400, and the axis of the left - right hand adjustment screw rod 910 is parallel to the length direction of the side steering support assembly 400. One end of the left - right hand adjustment screw rod 910 is connected to the output end of the adjustment motor 950; the two adjustment sliders 920 are provided on the side steering support assembly 400, and the adjustment sliders 920 are slidably matched with the guide rod 940. The guide rod 940 is arranged on the side steering support assembly 400 along the left - right hand adjustment screw rod 910. Both ends of the left - right hand adjustment screw rod 910 respectively penetrate through the adjustment sliders 920 in a spiral manner, and an upper rack 930 is provided on each adjustment slider 920. The two upper racks 930 are respectively engaged with the two lower steering gears 540; in the embodiment of the present invention, the adjustment motor 950 drives the left - right hand adjustment screw rod 910 to rotate, and the rotating left - right hand adjustment screw rod 910 drives the two adjustment sliders 920 to move towards or away from each other. The two upper racks 930 respectively move with the corresponding adjustment sliders 920, and the upper rack 930 drives the upper steering shaft 530 to rotate by engaging with the corresponding lower steering gear 540.

[0027] In one embodiment, as Figures 1-5 shown, the side clamping portion 550 includes a clamping turntable 551, a lower support plate 552 and an upper clamping frame 553. Both ends of the clamping turntable 551 are rotatably connected to the side of the upper support frame 510 through supports. The lower support plate 552 is arranged between the clamping turntable 551 and the upper support frame 510, and the end of the lower support plate 552 away from the upper support frame 510 extends to the upper side of the support roller 520. The upper clamping frame 553 is arranged on the side wall of the clamping turntable 551 away from the upper support frame 510, and a clamping roller 554 rotatably connected thereto is provided at the end of the upper clamping frame 553 away from the clamping turntable 551; in the embodiment of the present invention, when the upper support frame 510 tilts towards one side of the side clamping portion 550, the thick plate slides towards one side of the side clamping portion 550, and the lower support plate 552 contacts the side of the thick plate. Due to the gravity of the thick plate, the thick plate pushes the lower support plate 552 to rotate, and the lower support plate 552 drives the clamping turntable 551 and the upper clamping frame 553 to rotate. Furthermore, the clamping roller 554 rotates towards the surface of the thick plate and the clamping roller 554 rolls on the surface of the thick plate, preventing the thick plate from detaching from the upper support frame 510 due to tilting.

[0028] In one embodiment, as Figure 2 and Figure 3 shown, the side fixing plate 600 is slidably matched with the auxiliary support portion 100. A lower limit block 110 is arranged on the auxiliary support portion 100 and located below the side fixing plate 600. The side steering support assembly 400 includes a lower steering bracket 410, a lower steering shaft 420 and a lower inclined lifting portion 430. Both ends of the lower steering shaft 420 are respectively rotatably connected to two side fixing plates 600, and one end of the lower steering shaft 420 is connected to the output end of the side steering motor 700. The lower steering bracket 410 is arranged on the lower steering shaft 420 and the lower steering bracket 410 is used to support the upper steering support assembly 500. There are two lower inclined lifting portions 430, and the two lower inclined lifting portions 430 are respectively arranged at both ends of the lower steering shaft 420, and the lower end of the lower inclined lifting portion 430 is in rolling contact with the bottom of the auxiliary support portion 100; in the implementation of the present invention, the side steering motor 700 drives the lower steering shaft 420 to rotate, and the lower steering shaft 420 drives the lower steering bracket 410 and the lower inclined lifting portion 430 to rotate; when the lower inclined lifting portion 430 rotates from an inclined state to a vertical state, the lower inclined lifting portion 430 can push the lower steering bracket 410 and the lower steering shaft 420 to move upward, and thus the upper steering support assembly 500 and the thick plate can be moved upward, thereby preventing interference between the thick plate and the belt conveying portion 200 when the thick plate rotates to a vertical state; when the lower inclined lifting portion 430 rotates from a vertical state to an inclined state, the lower steering shaft 420 and the lower steering bracket 410 move downward and the upper steering support assembly 500 moves down to the initial position.

[0029] In one embodiment, as Figure 2 and Figure 3As shown, the lower inclined lifting part 430 includes a connecting sleeve 431 and two inclined support arms 432. The connecting sleeve 431 is fixedly sleeved on the lower steering shaft 420, and the two inclined support arms 432 are respectively fixed on the two side walls of the connecting sleeve 431. A support roller 433 is provided at the end of the inclined support arm 432 far from the connecting sleeve 431, and the support roller 433 is in rolling contact with the bottom of the auxiliary support part 100. In the implementation of the present invention, when the lower steering bracket 410 is in a horizontal state, both support rollers 433 are in rolling contact with the bottom of the auxiliary support part 100. When the lower steering shaft 420 rotates driven by the side steering motor 700, one of the support rollers 433 rolls relative to the bottom of the auxiliary support part 100, and then one of the inclined support arms 432 rotates from an inclined state to a vertical state, so that the inclined support arm 432 jacks up the lower steering shaft 420 and the lower steering bracket 410 upward, and the lower steering bracket 410 and the upper steering support assembly 500 move upward.

[0030] In one embodiment, as Figure 2 and Figure 3 shown, a positioning assembly 800 is further provided in the middle of the lower steering bracket 410, and the positioning assembly 800 includes a positioning slideway 810 and a positioning baffle 820. The positioning slideway 810 is fixed in the middle of the lower steering bracket 410 and is arranged along the width direction of the lower steering bracket 410. The positioning baffle 820 is slidably arranged on the positioning slideway 810 and can be pulled out from both ends of the positioning slideway 810. Pull rods 830 are provided at both ends of the positioning baffle 820. In the embodiment of the present invention, when the two upper steering support assemblies 500 incline towards each other, the thick plates slide along the upper steering support assemblies 500 towards the middle position. When the welding edges of the two thick plates come into contact with the side surface of the positioning baffle 820, hold the pull rod 830 and pull the positioning baffle 820 out of the positioning slideway 810, so that the welding edges of the two thick plates can be butted together at the middle position of the lower steering bracket 410, and when the positioning baffle 820 is pulled out, the welding edges of the thick plates can be ground, which is convenient for subsequent welding operations.

[0031] The above embodiments provide a thick plate welding auxiliary device, wherein two belt conveying parts 200 work synchronously and convey two thick plates to two upper turning supporting components 500; when the front ends of the thick plates are on the corresponding upper turning supporting components 500 and the front ends of the two thick plates are in contact, the belt conveying parts 200 stop working; if the two thick plates are welded face to face, the welding operator welds the contacting parts at the front ends of the two thick plates from the upper side; if the two thick plates need to be welded at an angle, the angle adjustment driving component 900 drives the two upper turning supporting components 500 to rotate synchronously and in opposite directions, and the opposite ends of the two upper turning supporting components 500 rotate downward, so that the two thick plates rotate with the upper turning supporting components 500 and form an angle. At this time, the welding operator welds the contacting parts at the front ends of the two thick plates from the upper surface; after the welding on the upper surface of the thick plate is completed, the side turning motor 700 drives the side turning support component 400 to rotate and the side turning support component 400 turns downward toward the side where the side clamping part 550 is located, so that the two welded thick plates slide laterally along the upper turning supporting components 500 until the upper turning supporting components 500 and the thick plates are in a vertical state, and the side of the thick plate is supported by the side clamping part 550 and the side clamping part 550 presses the thick plate to prevent the thick plate from detaching from the upper turning supporting components 500; then the welding operator can weld the two thick plates from the non-welded side of the thick plate. Since the thick plate is in a vertical state, it is convenient for welding operation and double-sided welding, ensuring the welding firmness; after welding is completed, the side turning motor 700 drives the side turning support component 400 to rotate in the reverse direction and makes the side where the side clamping part 550 is located tilt upward, so that the welded thick plate automatically slides out from the side of the upper turning supporting components 500 away from the side clamping part 550, and automatic blanking can be achieved; after blanking is completed, the angle adjustment driving component 900 and the side turning motor 700 drive the side turning support component 400 and the upper turning supporting components 500 to return to the initial horizontal state.

[0032] As described above, the above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present disclosure, and all should be covered by the protection scope of the present disclosure.
