Description

Technical Field

[0001] The invention relates to the technical field of ship production equipment, in particular to a welding device for ship steel structures. Background Art

[0002] Ship steel structure welding equipment is a professional equipment used for welding steel structures during shipbuilding and repair. Welding is one of the key process technologies of modern shipbuilding engineering. With the advancement of modern civilization and science and technology, the shipbuilding industry has developed greatly, and the development and renewal of ship materials have directly promoted the development of ship welding technology. Welding technology not only improves the efficiency and quality of shipbuilding, but also promotes the large-scale and diversification of ships. In the shipbuilding process, steel structure welding equipment is widely used in welding operations of hull structures, turbine equipment, piping systems, etc. These devices use heating, pressurization or both to achieve atomic bonding between two separated metal surfaces to form a permanent connection. Arc welding is one of the most commonly used methods in ship welding. It melts and connects metals together through the high temperature generated by the arc; resistance welding is a method of melting and connecting metals together through the resistance heat generated by the current. Common resistance welding devices include spot welding, seam welding, etc.

[0003] After searching, the patent document (authorization announcement number is CN117381257A) includes a mobile base, a rectangular rod is fixedly installed on one side of the top of the mobile base, a first slide groove is opened in the middle of one side of the rectangular rod, and a second slide groove is opened in the middle of the other side of the rectangular rod. A first motor is fixedly installed on one side of the bottom of the mobile base, and a first threaded rod is fixedly installed on one end of the output shaft of the first motor through a coupling, and the top of the first threaded rod passes through the mobile base and is rotatably connected to the top of the inner wall of the first slide groove. By arranging a support assembly and a clamping assembly on the surface of the first threaded rod, under the action of the first motor and the first threaded rod, the support assembly and the clamping assembly can move up and down normally, which is convenient for welding the ship steel structure from different heights and different positions using a welding gun head, and does not require workers to climb up to ensure the safety of workers.

[0004] However, the above device still has shortcomings:

[0005] 1. When welding the ship's steel structure, due to the large overall structure of the ship's steel structure, welding operations need to be performed at multiple points. During welding, metal residues will be generated, and these residues will spread on the surface of the ship's steel structure, thereby affecting the welding effect of other parts of the ship's steel structure.

[0006] 2. During welding, since the device needs to work for a long time, the temperature of the welding device body will continue to rise. If the device is in a high temperature state for a long time, this will greatly reduce the overall life of the device and even cause damage to the device. Summary of the invention

These wind forces are directly sprayed onto the surface of the ship's steel structure through the ventilation duct, thereby achieving the cleaning effect on the surface of the ship's steel structure, avoiding welding residues left on its surface, which leads to the problem of poor subsequent welding effect.

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The bottom of the slide rail 43 is slidably connected to a slide rod 44, the bottom of the slide rod 44 is fixedly connected to a plate 45, the top of the plate 45 is fixedly connected to a plurality of driving cylinders 46, the interior of the driving cylinder 46 is inserted with a clamping rod 47, and the clamping rod 47 is slidably connected to the plate 45.

[0031] A welding device housing 5 is disposed above the workbench 1 , and a welding gun body 51 is plugged into the bottom of the welding device housing 5 .

[0032] A cooling treatment component 6 is provided inside the welding device housing 5, and the cooling treatment component 6 includes a first box body 61, which is fixedly connected to the inner bottom of the welding device housing 5, and one end of the welding gun body 51 arranged in the welding device housing 5 is slidably connected in the first box body 61, and the welding device housing 5 is slidably connected with a built-in driving rod 52, and the top of the welding gun body 51 is slidably connected with the built-in driving rod 52, and the inside of the welding device housing 5 is fixedly connected with a second box body 62, and the top of the built-in driving rod 52 is slidably connected in the second box body 62, and one end of the built-in driving rod 52 arranged in the second box body 62 is fixedly connected with a piston push plate 53, and the piston push plate 53 is slidably connected in the second box body 62, and the side wall of the second box body 62 is provided with a through hole 64, and the side wall of the first box body 61 is fixedly connected with a connecting pipe 65, and the inner wall of the welding device housing 5 is provided with an inner hole 63, and the through hole 64 and the connecting pipe 65 are both connected to the inner hole 63.

[0033] By setting the cooling treatment component 6, after the welding operation of the welding gun body 51, the welding gun body 51 is retracted into the welding device housing 5, and the cooling liquid in the welding device housing 5 enters the first box 61 through the inner hole 63 and the through hole 64 through the push of the piston push plate 53, so as to cool the part of the welding gun body 51 in the first box 61. Such a design makes it possible to cool the welding gun body 51 each time after the welding gun body 51 completes its work, avoiding the problem of insufficient temperature during its work. Secondly, each time the welding gun body 51 is retracted, only a certain amount of cooling liquid will be squeezed out, avoiding the problem of storing all the cooling liquid together, thereby causing all the cooling liquid to be contaminated.

The ship steel structure 3 is arranged above the conveyor belt 2 . The driving cylinders 46 are distributed on both sides of the slide bar 44 .

[0035] A cleaning assembly 7 is provided inside the welding device housing 5, and the cleaning assembly 7 includes a ventilation duct 71, which is fixedly connected to the bottom of the second box body 62, and the bottom of the ventilation duct 71 passes through the welding device housing 5 and extends to the outside thereof, and a threaded rod 72 is provided inside the ventilation duct 71, and the top of the threaded rod 72 is fixedly connected to the piston push plate 53, and the bottom of the second box body 62 is fixedly connected to a fixing plate 73, and the surface of the fixing plate 73 is rotatably connected to a fan blade 74, and the fan blade 74 is threadedly connected to the outside of the threaded rod 72, and the fixing plate 73 is rotatably connected to the outside of the fixing plate 73.

[0036] Through the setting of the cleaning component 7, when moving from one part to another part after welding, the cooling treatment component 6 is started to operate. When the cooling treatment component 6 is in operation, the piston push plate 53 drives the threaded rod 72 to move, and then under the premise that the fan blade 74 and the threaded rod 72 are threadedly connected, the threaded rod 72 drives the fan blade 74 to rotate, and the fan blade 74 generates wind force through its own rotation. These wind forces are directly sprayed onto the surface of the ship steel structure 3 through the ventilation duct 71, thereby achieving the cleaning effect on the surface of the ship steel structure 3, avoiding welding residues remaining on its surface, thereby causing the problem of poor subsequent welding effect.

[0037] An inner sliding groove 66 is provided on the inner wall of the second box body 62, and a first one-way rotating rod 67 is rotatably connected to the inner wall of the inner sliding groove 66. A first rotating shaft 68 is fixedly connected to the side wall of the first one-way rotating rod 67. The first rotating shaft 68 is rotatably connected in the inner sliding groove 66. A first torsion spring 69 is sleeved on the outer side of the inner sliding groove 66. A second locking tooth 531 is fixedly connected to the side wall of the piston push plate 53. Through the coordinated arrangement of the first one-way rotating rod 67, the first rotating shaft 68 and the first torsion spring 69, the piston push plate 53 can only rise but not fall in the second box body 62. In this way, it can be ensured that the cooling liquid in the second box body 62 can be discharged every time the piston push plate 53 moves.

[0038] The inner wall of the welding gun body 51 is rotatably connected with the second one-way rotating rod 8, the side wall of the second one-way rotating rod 8 is fixedly connected with the second rotating shaft 81, the second rotating shaft 81 is rotatably connected to the inner wall of the welding gun body 51, the outer side of the second rotating shaft 81 is sleeved with a second torsion spring 82, the built-in driving rod 52 is arranged at the bottom of one end in the welding gun body 51 and is fixedly connected with the first latching tooth 521, through the cooperation of the second one-way rotating rod 8, the second rotating shaft 81 and the second torsion spring 82, the built-in driving rod 52 can only be moved toward the welding gun body 51 When the welding gun body 51 is retracted into the welding device housing 5, the built-in driving rod 52 can drive the piston push plate 53 to move upward, and when the welding gun body 51 moves out of the welding device housing 5, the piston push plate 53 is blocked by the first one-way rotating rod 67 and cannot move. The built-in driving rod 52 cannot move due to the fixed action of the piston push plate 53, so that the built-in driving rod 52 is away from the welding gun body 51, so that each movement of the welding gun body 51 can drive the piston push plate 53 to move upward.

[0039] Working principle: After the welding operation of the welding gun body 51, the welding gun body 51 is retracted into the welding device housing 5, and the cooling liquid in the welding device housing 5 enters the first box body 61 through the inner hole 63 and the through hole 64 through the push of the piston push plate 53, thereby cooling the part of the welding gun body 51 in the first box body 61;

[0040] When moving to other parts after welding one part, the cooling treatment component 6 is started. When the cooling treatment component 6 is in operation, the piston push plate 53 drives the threaded rod 72 to move, and then the threaded rod 72 drives the blades 74 to rotate under the premise of threaded connection between the blades 74 and the threaded rod 72. The rotation of the blades 74 generates wind force, which is directly sprayed onto the surface of the ship steel structure 3 through the ventilation duct 71, thereby achieving a cleaning effect on the surface of the ship steel structure 3.

[0041] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
