Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a welding device and method for assembling structural parts with a weld quality inspection function. Background Art

[0002] Ship structures refer to various structural components and parts used in the construction and operation of ships. The design and manufacture of these structural parts are crucial to the strength, stability and safety of ships. Ship structural welding is an important part of ship manufacturing and maintenance, involving the joining of metal structural parts through welding processes to form a solid whole.

[0003] The quality of welding directly affects the safety and service life of ships. Most welding processes in existing shipbuilding usually require manual assistance, which requires the cooperation of multiple workers. This method not only consumes a lot of man-hours and is inefficient, but also fails to effectively monitor and inspect the welds at the welds, making it impossible to control the welding quality. Summary of the invention

When the base belt is a first unconnected conveyor chain plate after disassembly, the base belt is fixed on the hoisting rack so that the base belt acts as a guide rail. At this time, the workbench and the side plate are in an inverted state, so it is necessary to flip the carrier plate 180° on the workbench, and the rodless cylinder works to drive the rack plate to move through the slider. During the movement, the rack plate rotates the steering gear, and the steering gear flips the carrier plate through the rotating shaft, so that the carrier plate completes a 180° flip, so that the laser is still in a downward state.

The control system calculates the resistance value of the welding points according to Ohm's law, and verifies the welding quality of the welding points again through the resistance value. When the electrode sheets and electromagnetic parts within the coverage range of the ferrule are energized, the driving roller rotates and drives the baseband to run, and the side plate also forms a relative position with the baseband, so that the bearing column located in the coverage range of the ferrule moves out of the coverage range, so that the electrode sheets and electromagnetic parts are naturally powered off. No additional control by the control system is required.

When the base belt moves on the structural parts to be welded, the current flows through the welding point. Using Ohm's law, the control system calculates the resistance and further obtains the welding quality of the weld.

[0029] Working principle of the present invention: When welding a structural member, place the welding device on the structural member. When the angle between the two components constituting the structural member is 90°, the adjusting cylinder 4 adjusts the angle between the side panel 2 and the workbench 1 by contracting the cylinder rod, so that the workbench 1 and the side panel 2 can adapt to the structural member with a 90° angle, so that the workbench 1 is in a 45° inclined state; when the angle between the two components constituting the structural member is 180°, the workbench 1 and the side panel 2 are in a mutually parallel state.

[0030] When the base belt 7 is a conveyor belt or a first connected conveyor chain plate, the driving disc 3 drives the driving roller 8 to rotate, and the base belt 7 runs. When the base belt 7 drives the workbench 1 to move between the structural parts to be welded, the laser welds the weld seam driven by the workbench 1.

[0031] When the base belt 7 moves on the structural part, the control system in the control box 5 connects the copper sheet to the circuit, and then connects the electromagnetic part 21 and the electrode sheet 18 to the circuit through the metal contact. The electromagnetic part 21 is energized to generate a magnetic field and magnetically attract the structural part to prevent the base belt 7 from deviating from the direction when moving on the structural part; The electrode sheet 18 and the electromagnetic component 21 within the coverage of the card sleeve 9 are energized. When the driving roller 8 rotates and drives the base belt 7 to run, the side plate 2 and the base belt 7 are in relative position, so that the bearing column 10 located in the coverage of the card sleeve 9 moves out of the coverage, so that the electrode sheet 18 and the electromagnetic component 21 are naturally powered off, and no additional control by the control system is required. The electrode sheet 18 and the electromagnetic component 21 corresponding to the bearing column 10 newly entering the coverage of the card sleeve 9 will automatically connect to the circuit and work; The electrode sheets 18 on the two base strips 7 cooperate with each other to allow current to flow through the welding point of the structural parts. The control system calculates the resistance value of the welding point according to Ohm's law, and verifies the welding quality of the welding point again through the resistance value.

[0032] According to the welding position of the structural parts, the base belt 7 can be disassembled. When the base belt 7 is disassembled into the first unconnected conveyor chain plate, the base belt 7 is fixed on a hoisting or overhead rack, so that the base belt 7 is inverted in the air and acts as a guide rail. The clamping sleeve 9 is installed on the bearing column 10 through the electrode column and the notch 20. The clamping sleeve 9 acts as a slider and drives the side plate 2 to move on the base belt 7. The overall length of the base belt 7 can be automatically increased according to work requirements; When the base belt 7 is inverted, since the workbench 1 and the side plate 2 are also in an inverted state, it is necessary to first flip the carrier plate 12 on the workbench 1 by 180° when the base belt 7 is not inverted. The rodless cylinder 16 works under the control of the control system and drives the rack plate 14 to move through the slider. During the movement, the rack plate 14 rotates the steering gear 15, and the steering gear 15 flips the carrier plate 12 through the rotating shaft, so that the carrier plate 12 completes a 180° flip, so that the laser is still in a downward state. The laser welds the weld.

[0033] The thermal imagers 6 are distributed in front and behind the laser in the forward direction. There is always a thermal imager 6 located behind the laser. After the laser welds the weld, the thermal imager 6 collects data on the position after welding. The control system processes the data fed back by the thermal imager 6 to obtain the welding quality of the weld.

[0034] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
