Description

Technical Field

[0001] The utility model relates to the technical field of ship production equipment, in particular to a welding mechanism for ship curved plates. Background Technique

[0002] Limited by the size of production equipment, steel plates as long as the ship cannot be produced. Additionally, due to the curvature of the ship's hull, the steel plates of the hull are welded in sections. Welding flat steel plates is relatively simple. Align the two ends, ensure the two steel plates are flush, and then leave a weld seam. However, when welding curved steel plates, aligning the steel plates is rather troublesome, and the fixing and supporting of curved steel plates cannot use the fixing devices for flat plates.

[0003] A welding mechanism for ship curved plates provided in Application No. 202223139630.6 includes a main body of the welding mechanism. One end of the main body of the welding mechanism is provided with a welding part mounting seat. The top of the welding part mounting seat is provided with a hydraulic telescopic rod. One end of the hydraulic telescopic rod is provided with a rubber sleeve. The top of the rubber sleeve is provided with a pressing plate. There are two groups of pressing plates, and the two groups of pressing plates are symmetrically distributed with respect to the center line of the welding fume extraction machine. A rubber pad is provided on the outer wall of one side of the pressing plate. A welding fume extraction machine is provided on one side of the top of the main body of the welding mechanism. A rack is provided inside the main body of the welding mechanism.

[0004] This device adjusts the height and angle of the welding part by adjusting the height of each hydraulic telescopic rod, and applies pressure to the welding part from above by using the pressing plate to improve the fixing strength of the device for the welding part. However, in actual production, the surface of the steel plate is not completely clean, and there will be iron filings, rust, dust, etc. remaining on the surface, which will all affect the friction of the rubber parts, thus affecting the fixing strength of the welding part. In addition, the pressing plate rotates around the top of the pressing plate support column through a rotating arm. When the pressing plate is horizontal and contacts the center of the four hydraulic rods, the pressure applied to the welding part is vertically downward. However, when the contact point deviates from the center of the four hydraulic rods or the pressing plate has an angle with the horizontal direction, the pressure applied to the welding part has an angle with the vertical direction, thus affecting the pressure on the welding part and further affecting the fixing strength of the welding part.

[0030] Embodiment 1:

[0031] Please refer to Figures 1-5 , and the above technical solutions of the present utility model are described in detail through the following embodiments:

[0032] A welding mechanism for a ship's curved panel, comprising:

[0033] A base 1, the base 1 includes a bottom plate 11, a fixed seat 12 is fixedly installed on the left side of the top surface of the bottom plate 11 by bolts, a sliding seat 14 is provided on the right side of the fixed seat 12 through a lateral movement assembly, the lateral movement assembly is used to drive the sliding seat 14 to move horizontally, and a welding fixture 2 is provided on the top surfaces of the fixed seat 12 and the sliding seat 14.

[0034] The bottom plate 11 is used to contact the ground to keep the device stable.

[0035] The lateral movement assembly includes a first guide rail 13, the first guide rail 13 is slidably connected to the sliding seat 14, a first oil cylinder 15 is fixedly installed between the first guide rails 13 by bolts, and the piston rod of the first oil cylinder 15 is clamped with the sliding seat 14.

[0036] The first guide rail 13 is fixedly installed on the top surface of the bottom plate 11 by bolts, and the first guide rail 13 is used to limit the sliding direction of the sliding seat 14. By controlling the operation of the first oil cylinder 15, the sliding seat 14 can be driven to move along the first guide rail 13, thereby controlling the distance between the sliding seat 14 and the fixed seat 12.

[0037] The height of the sliding seat 14 is lower than that of the fixed seat 12. A distance measuring assembly 16 is fixedly installed in the middle of the side of the top surface of the sliding seat 14 close to the fixed seat 12 by screws, and the distance measuring assembly 16 is used to measure the distance between the sliding seat 14 and the fixed seat 12.

[0038] The distance measuring assembly 16 can adopt a known infrared or laser distance measuring device, and the left end of the distance measuring assembly 16 is flush with the left side end face of the sliding seat 14.

[0039] The welding fixture 2 includes a magnetic base 24. A universal adjustment assembly is provided below the magnetic base 24. The universal adjustment assembly is used to adjust the angle of the top surface of the magnetic base 24. A magnetic switch 25 is provided on the side of the magnetic base 24. The magnetic switch 25 is used to control the on-off of the magnetism of the magnetic base 24. A second oil cylinder 26 is provided below the universal adjustment assembly on the top surface of the sliding seat 14. The second oil cylinder 26 is used to control the height of the universal adjustment assembly on the top surface of the sliding seat 14, so as to control the height and angle of the steel plate above the sliding seat 14.

[0040] The magnetic base 24 can adopt a well-known magnetic seat. The external is a soft magnetic material shell, which is divided into two symmetrical parts. The two shells are fixedly welded by a non-magnetic metal. There is a cylindrical space in the middle of the shell. A strip-shaped permanent magnet is rotatably installed inside. The permanent magnet is clamped with the magnetic switch 25. By rotating the magnetic switch 25, the permanent magnet can be driven to rotate. When the two poles of the magnet are in the up-down direction, that is, when the N or S pole of the magnet faces the soft magnetic material shell, the shell is magnetized and has strong magnetism in this direction, so it can be used to suck the steel surface. Since there is only extremely small magnetism in the exact middle of the long strip magnet, it can be ignored. When the two poles of the magnet are in the horizontal direction, that is, when the exact middle of NS faces the soft magnetic material shell, the shell will not be magnetized, so there is almost no magnetism on the shell at this time, and it can be easily taken off from the steel surface.

[0041] The universal adjustment assembly includes a ball head seat 21. A ball head 22 is rotatably installed on the ball head seat 21. The top of the ball head seat 21 is threadedly connected with a damping adjustment bolt 23. The top end of the damping adjustment bolt 23 penetrates the ball head seat 21 and abuts against the ball head 22.

[0042] By rotating the damping adjustment bolt 23, the pressure of the damping adjustment bolt 23 on the ball head 22 can be controlled, so as to control the friction force between the ball head 22 and the ball head seat 21, and further change the ease of rotation of the ball head 22.

[0043] The magnetic base 24 is fixedly installed on the top surface of the ball head 22 by screws. Using the rotational connection between the ball head 22 and the ball head seat 21, the magnetic base 24 can be turned to any angle within a limited range, so as to adapt to steel plates with any curvature.

[0044] Through the cooperation of multiple universal adjustment assemblies and the magnetic base 24, the adsorption and fixation of steel plates with any curved surface can be realized.

[0045] The second oil cylinder 26 is fixedly installed on the top of the sliding seat 14 by bolts. The piston rod of the second oil cylinder 26 is vertically upward. A ball head seat 21 is fixedly installed on the top pipe of the piston rod of each second oil cylinder 26.

[0046] Controlling the operation of the second oil cylinder 26 can drive the ball head seat 21 to move in the vertical direction, so as to control the magnetic base 24 to move in the vertical direction, and further control the height and angle of the steel plate adsorbed on the top surface of the magnetic base 24.

[0047] Adjusting assembly 3, the adjusting assembly 3 includes a third oil cylinder 31 and a fourth oil cylinder 35. The third oil cylinder 31 is fixedly installed at the center of the top surface of the sliding seat 14 through bolts. The fourth oil cylinder 35 is installed on the top surface of the bottom plate 11 through a sliding device. The sliding device is used to adjust the position of the fourth oil cylinder 35. The third oil cylinder 31 and the fourth oil cylinder 35 clamp the steel plate through a rolling device, and the rolling device is used for the forward and backward movement of the steel plate.

[0048] The sliding device includes a gantry 33. The gantry 33 is slidably installed on the top surface of the bottom plate 11 near one side of the sliding seat 14 through a second slide rail 34. The fourth oil cylinder 35 is fixedly installed at the middle of the inner top surface of the gantry 33 through bolts, and the piston rod of the fourth oil cylinder 35 is vertically downward.

[0049] The second slide rail 34 is fixedly installed on the top surface of the bottom plate 11 through bolts. There are two second slide rails 34, and the two second slide rails 34 are installed in parallel on the front and rear sides of the sliding seat 14. The gantry 33 can slide along the second slide rail 34, so as to drive the fourth oil cylinder 35 to move left and right, and further ensure that the axes of the fourth oil cylinder 35 and the third oil cylinder 31 coincide.

[0050] The rolling device includes a supporting roller 32 and a pressing roller 36. The supporting roller 32 is rotatably installed at the top end of the piston rod of the third oil cylinder 31. The pressing roller 36 is rotatably installed at the top end of the piston rod of the fourth oil cylinder 35. The rotation axes of the supporting roller 32 and the pressing roller 36 are parallel.

[0051] After the axes of the fourth oil cylinder 35 and the third oil cylinder 31 coincide, control the third oil cylinder 31 and the fourth oil cylinder 35 to work, which can drive the supporting roller 32 and the pressing roller 36 to move, so as to control the distance between the supporting roller 32 and the pressing roller 36.

[0052] After the supporting roller 32 and the pressing roller 36 clamp the steel plate, the steel plate can move along the rotation direction of the supporting roller 32 and the pressing roller 36, that is, move backward. When the steel plate moves forward and backward, it still follows its own curvature, and thus the forward and backward adjustment of the position of the steel plate is realized without changing the height of the steel plate.

[0053] When an operator uses this device, first place one of the steel plates to be welded on the top surface of the fixed seat 12, adjust the angle of the magnetic base 24 to ensure that all the magnetic bases 24 are in contact with the bottom surface of the steel plate. Rotate the magnetic switch 25 to fix the steel plate and the magnetic base 24 through magnetism.

[0054] Place another steel plate above the sliding seat 14, and similarly adjust the angle of the magnetic base 24 to ensure that all the magnetic bases 24 are in contact with the bottom surface of the steel plate. Rotate the magnetic switch 25 to fix the steel plate and the magnetic base 24 through magnetism.

[0055] Control the operation of the second oil cylinder 26 to adjust the height of the steel plate above the sliding seat 14, ensuring that the welding ends of the steel plates above the sliding seat 14 and the fixed seat 12 are approximately flush. Then maintain the pressure of the second oil cylinder 26.

[0056] Control the operation of the first oil cylinder 15 to drive the sliding seat 14 close to the fixed seat 12 until the welding ends of the two steel plates abut against each other. Use the distance measuring component 16 to measure the distance between the sliding seat 14 and the fixed seat 12 at this time and record it as the initial value.

[0057] Control the operation of the second oil cylinder 26 to adjust the height and angle of the steel plate above the sliding seat 14, ensuring that the welding ends of the steel plates above the sliding seat 14 and the fixed seat 12 are at the same height and have a smooth curvature. Then maintain the pressure of the second oil cylinder 26.

[0058] Control the operation of the third oil cylinder 31 to drive the support roller 32 to rise and hold against the bottom surface of the steel plate. Then move the gantry 33 and drive the fourth oil cylinder 35 to move until the axes of the fourth oil cylinder 35 and the third oil cylinder 31 coincide.

[0059] Then control the operation of the fourth oil cylinder 35 to drive the pressing roller 36 to descend until the pressing roller 36 holds against the top surface of the steel plate.

[0060] At this time, turn the magnetic switch 25 of the magnetic base 24 on the top surface of the sliding seat 14 to make the corresponding magnetic base 24 lose magnetism.

[0061] At this time, the steel plate can move along the rotation direction of the support roller 32 and the pressing roller 36. Adjust the front and rear positions of the steel plate to align it with the front and rear sides of the steel plate above the fixed seat 12. Then turn on the magnetic switch 25 of the magnetic base 24 on the top surface of the sliding seat 14 to make the corresponding magnetic base 24 adsorb the steel plate again, completing the adjustment of the position of the steel plate.

[0062] At this time, the two steel plates have the same height, the end faces are aligned, and the curvature is smooth.

[0063] Control the operation of the third oil cylinder 31 and the fourth oil cylinder 35 to drive the support roller 32 and the pressing roller 36 to separate from the steel plate. Move the gantry 33 to make the fourth oil cylinder 35 move out of the range of the steel plate.

[0064] Then control the operation of the first oil cylinder 15 to drive the sliding seat 14 away from the fixed seat 12, and at the same time use the distance measuring component 16 to measure the change in the distance between the sliding seat 14 and the fixed seat 12 in real time.

[0065] Determine the weld width according to the thickness of the steel plate. Stop the operation of the first oil cylinder 15 when the difference between the distance between the sliding seat 14 and the fixed seat 12 measured by the distance measuring component 16 and the initial value is equal to the required weld width.

[0066] After the adjustment of the steel plate is completed, welding can be carried out.
