Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and specifically discloses a welding device for a steel casing. Background Art

[0002] During the processing of steel casing, it is usually necessary to connect and fix the various structures of the steel casing by welding after the various structures are processed and formed. During the welding process, in order to improve the stability of the welding process and avoid deformation of the steel casing due to improper operation during the processing, welding equipment is usually used to improve the stability of the steel casing during the welding process. Most of the current welding equipment cannot position the steel casing, which makes the steel casing easy to shake, causing inconvenience to the welding operation.

[0003] In order to solve the above-mentioned problem, a welding box which can position the steel casing has appeared on the market. The welding box has an inlet and an outlet, and a welding assembly and a positioning assembly are arranged inside the welding box. Workers use a robotic arm to gradually push the steel casing into the welding box along the inlet. After the steel casing is placed, the positioning assembly is used to position the steel casing. After the positioning assembly has positioned the steel casing, the welding assembly is used to weld the places on the steel casing that need to be welded, so that the welding operation of the steel casing can be carried out efficiently. Through the above process, the entire operation does not require manual operation, and the steel casing can be automatically welded and positioned, which improves the welding efficiency and ensures the quality after the welding is completed.

[0004] The above-mentioned device has the following problems during actual use: when the welding assembly is used to weld the steel casing, the heat generated after the welding is completed is too high. The excessively high temperature can easily burden the metal material, causing damage to the metal material, reducing the use effect, and affecting the welding quality; in addition, a large amount of harmful gas will be generated during welding. The harmful gas will splash in the absence of coolant, thereby causing pollution to the working environment and harm to human life and health. Summary of the invention

[0005] The invention provides a welding device for a steel casing, so as to solve the problem that the existing welding device cannot cool the welding position of the steel casing during welding.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a welding device for a steel casing, comprising a box body with an inlet and an outlet, and also comprising a welding mechanism arranged in the box body; the welding mechanism comprises an installation box, a welding head, a purification box, a piston cylinder, a piston block, and a driving assembly for driving the piston block to reciprocate along the length direction of the piston cylinder; the installation box is fixedly connected to the box body; the welding head, the purification box, and the piston cylinder are all fixedly connected to the installation box; the piston block is slidably connected to the piston cylinder; a water inlet pipe and a water outlet pipe are provided on the piston cylinder; the two ends of the water inlet pipe are respectively connected to the piston cylinder and the purification box; the water outlet pipe is connected to the piston cylinder, and the water outlet pipe is communicated with the piston cylinder.

[0007] The principles and advantages of this solution are:

[0008] When the welding head is welding the steel casing, the piston cylinder is used to continuously pump and drain water, so that the welding position can be cooled quickly, thereby ensuring that the welding area will not be deformed or cracked due to excessive temperature. That is, the temperature during the welding process is effectively controlled, the impact on the metal material is reduced, and the welding quality and reliability are improved.

[0009] Moreover, the water outlet of the piston cylinder can effectively treat harmful gases generated during welding of the welding joint, thereby preventing the harmful gases from polluting the environment and causing harm to the human body.

[0010] Furthermore, it also includes a linkage part; the linkage part includes a linkage box, a linkage block, an atomizing nozzle, a conduit, a linkage hole opened on the linkage block, and a linkage unit used to drive the linkage block to reciprocate along the length direction of the linkage box; the linkage box is connected to the piston cylinder; the number of water outlet pipes is two; the water outlet pipe is connected to the linkage box, and the water outlet pipe is communicated with the linkage box; the atomizing nozzle and the conduit are respectively connected to the two water outlet pipes; the linkage block is slidably connected to the linkage box, the linkage block is attached to the water outlet pipe, and the water outlet pipe is located on the movement trajectory of the linkage hole.

[0011] Through the reciprocating motion of the linkage block, the linkage hole is intermittently connected with the two water outlet pipes.

[0012] When the water outlet of the atomizing nozzle is connected to the linkage hole, the liquid discharged from the water outlet pipe is atomized liquid. The atomized liquid can better handle the harmful gas generated during welding of the welding head, so that the harmful gas will not diffuse out, ensuring that the harmful gas generated during welding of the welding head will not pollute the environment and cause harm to the human body.

[0013] When the water outlet pipe where the conduit is located is connected to the linkage hole, the liquid discharged from the water outlet pipe can be ejected with stronger force under the action of the conduit; after the liquid is pressurized through the conduit, the sputtering liquid formed when the liquid contacts the steel casing has a wider diffusion range, thereby further expanding the contact area between the sputtering liquid and the steel casing, ensuring that the position where the steel casing is welded can be quickly cooled down under the action of the sputtering liquid, thereby improving the cooling quality and cooling efficiency.

[0014] In summary, by setting two different modes of atomizing nozzle and conduit and exchanging them back and forth, the welding quality is comprehensively improved and the welding effect is enhanced.

[0015] During the reciprocating motion, the linkage block gradually communicates with the water outlet pipe through the linkage hole, thereby being able to change the water inlet diameter of the water outlet pipe to further enhance the force of liquid discharge, that is, the scope of liquid action is more comprehensive, the cooling effect is more significant, and the purification effect is more complete.

[0016] Furthermore, it also includes a blowing part; the blowing part includes a rotating shaft, a rotating blade, and a first gear; the rotating shaft is rotatably connected to a linkage box; the rotating blade and the first gear are both fixedly connected to the rotating shaft; the water outlet pipe is rotatably connected to the linkage box; a second gear is fixedly connected to the water outlet pipe; the first gear is located between the two second gears, and the first gear is respectively meshed with the two second gears; and it also includes a linkage part for driving the water outlet pipe to rotate.

[0017] During the rotation of the atomizing nozzle and the duct, the atomized liquid and the liquid can be diffused over a large area, ensuring that the atomized liquid can come into contact with the harmful gas more comprehensively and the contact area between the liquid and the steel casing is more sufficient, thereby further enhancing the purification effect and improving the cooling quality.

[0018] During the rotation of the rotating blades, cold air can be output to the steel casing, increasing the cooling method, so that the steel casing can be quickly cooled down with the cooperation of liquid and cold air; at the same time, during the rotation of the fan blades, the effective distance of the atomized liquid can be further increased and the effective range of the atomized liquid can be expanded, further making the purification effect of the atomized liquid on harmful gases more significant, that is, shortening the purification time and improving the purification efficiency.

[0019] Furthermore, a rubber tube is connected between the water outlet pipe and the atomizing nozzle; a rubber tube is connected between the water outlet pipe and the conduit; it also includes an extrusion part; the extrusion part includes a limit block, a slider, two arc blocks, and a power unit for driving the slider to reciprocate along the length direction of the limit block; the limit block is fixedly connected to the mounting box; the slider is slidably connected to the limit block; the two arc blocks are fixedly connected to the slider; the rubber tube is located on the movement trajectory of the arc block.

[0020] The rubber tube will continuously deform under the action of the arc block. During the deformation of the rubber tube, the diameter of the rubber tube will be squeezed and become smaller, thereby increasing the pressure inside the rubber tube. That is, after the rubber tube is deformed, the liquid sprayed out of the rubber tube can increase the action distance of the liquid and enhance the force of the liquid when it is sprayed out. As the diameter of the rubber tube gradually returns to its initial state, the distance of the liquid action also gradually returns to its initial state. Therefore, through the deformation of the rubber tube, the force of the liquid when it is sprayed out can be continuously adjusted, thereby ensuring that the atomized liquid can more thoroughly treat the harmful gas and the liquid can more fully cool the steel casing, that is, the effect of the atomized liquid and the liquid is comprehensively enhanced.

[0021] Furthermore, it also includes a cooling part; the cooling part includes a screw, a guide rod, a nut seat, a sponge block, and a driving unit for driving the screw to rotate; the screw is rotatably connected to the installation box; the guide rod is fixed to the installation box; the nut seat is threadedly connected to the screw; the nut seat is slidably connected to the guide rod; and the sponge block is fixed to the nut seat.

[0022] The water remaining on the steel casing will be absorbed by the sponge block, making the sponge block moist. On the one hand, it can lock in moisture and prolong the time that water acts on the surface of the steel casing, ensuring that the heat exchange process between water and steel casing can be fully carried out, enhancing the cooling effect on the weld, and making the temperature of the weld drop rapidly; on the other hand, it can also clean the weld surface and remove dust generated by welding, thereby ensuring that dust will not adhere to the steel casing and improving the cleanliness of the steel casing surface.

[0023] Furthermore, it also includes an air guide part; the air guide part includes an air guide cover, a long axis, fan blades, an air guide pipe, and a motion unit for driving the long axis to rotate; the air guide cover is fixedly connected to the installation box; the long axis is rotatably connected to the air guide cover; the fan blades are fixedly connected to the long axis; and both ends of the air guide pipe are respectively connected to the air guide cover and the purification box.

[0024] Through the rotation of the fan blades, all the harmful gases generated by welding can be sucked into the air guide hood, and then discharged into the purification box along the exhaust pipe, so that the harmful gases are purified under the treatment of liquid, ensuring that when the harmful gases are discharged again, there is no pollution to the environment and no harm to the human body.

[0025] Furthermore, it also includes a stirring unit; the stirring unit includes a first cam, a movable block, a first spring, a transverse block, a plurality of vertical blocks, and a side hole opened on the purification box; the first cam is fixedly connected to the long axis; the movable block is slidably connected to the linkage box, and the first cam is against the movable block; the two ends of the first spring are the movable block and the linkage box respectively; the transverse block is fixedly connected to the movable block, and the transverse block is slidably connected to the side hole; the plurality of vertical blocks are fixedly connected to the transverse block, and the vertical block is located in the purification box.

[0026] Through the reciprocating motion of the vertical block, the vertical block can fully stir the liquid and harmful gas in the purification box, so that the harmful gas and liquid are mixed more evenly and thoroughly, shortening the treatment time of the harmful gas, enhancing the treatment effect of the harmful gas, and improving the treatment efficiency of the harmful gas.

[0027] Furthermore, the driving assembly includes a rotating shaft, a second cam, a second spring, and a driving part for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the mounting box; the second cam is fixed to the rotating shaft, and the second cam is against the piston block; the two ends of the second spring are respectively connected to the piston block and the piston cylinder.

[0028] During the rotation of the shaft, the second cam rotates synchronously. During the rotation of the second cam, when the raised portion of the second cam abuts against the piston block, the piston block moves toward the position where the linkage box is located, and the second spring is compressed; when the raised portion of the second cam no longer abuts against the piston block, the piston block is reset under the action of the second spring, and the piston block moves away from the linkage box. Therefore, the piston block can reciprocate along the length direction of the piston cylinder.

[0029] Furthermore, the linkage unit is a connecting block; two ends of the connecting block are respectively fixedly connected to the linkage block and the movable block.

[0030] During the movement of the active block, the linkage block moves synchronously with the active block under the action of the connecting block.

[0031] Furthermore, the driving unit is a first rack and a third gear; the first rack is fixedly connected to the linkage block; the third gear is fixedly connected to the screw rod; and the first rack is meshed with the third gear.

[0032] During the movement of the linkage block, the first rack moves synchronously. During the movement of the first rack, the first rack meshes with the third gear, so that the third gear can rotate. During the rotation of the third gear, the screw rotates synchronously.

[0056] Specific implementation process:

[0057] The steel casing to be welded is driven by the robot arm to enter along the inlet, and the welding head 4 is used to weld the steel casing during the movement of the steel casing. During the welding of the welding head 4, the motor 46 is started, and the worm is driven to rotate by the output shaft of the motor 46. During the rotation of the worm, the second cam 37 rotates synchronously. During the rotation of the second cam 37, when the raised portion of the second cam 37 abuts against the piston block 7, the piston block 7 moves toward the position where the linkage box 10 is located, and the second spring 38 is compressed; when the raised portion of the second cam 37 no longer abuts against the piston block 7, the piston block 7 is reset under the action of the second spring 38, and the piston block 7 moves away from the linkage box 10. Therefore, the piston block 7 can reciprocate along the length direction of the piston cylinder 6.

[0058] During the reciprocating motion of the piston block 7, the piston cylinder 6 continuously pumps and drains water, so that the welding position can be quickly cooled, thereby ensuring that the welding area will not be deformed or cracked due to excessive temperature. That is, the temperature during the welding process is effectively controlled, the impact on the metal material is reduced, and the welding quality and reliability are improved.

[0059] Furthermore, the water discharge from the piston cylinder 6 can effectively treat harmful gases generated during welding of the welding joint 4, thereby preventing the harmful gases from polluting the environment and causing harm to the human body.

[0060] During the rotation of the worm, the worm wheel 45 is engaged with the worm, so that the worm wheel 45 rotates. During the rotation of the worm wheel 45, the long shaft 28 rotates synchronously. During the rotation of the long shaft 28, the first cam 31 rotates synchronously. During the rotation of the first cam 31, when the raised portion of the first cam 31 abuts against the movable block 32, the movable block 32 moves toward the position where the linkage box 10 is located, and the first spring 33 is compressed; when the raised portion of the first cam 31 no longer abuts against the movable block 32, the movable block 32 is reset under the action of the first spring 33, and the movable block 32 moves away from the linkage box 10. Therefore, the movable block 32 can reciprocate along the length direction of the linkage box 10.

[0061] During the movement of the movable block 32, the linkage block 11 moves synchronously with the movable block 32 under the action of the connecting block 39. Through the reciprocating motion of the linkage block 11, the linkage hole 14 is intermittently connected with the two water outlet pipes 9 respectively.

[0062] When the water outlet hole where the atomizing nozzle 12 is located is connected to the linkage hole 14, the liquid discharged from the water outlet pipe 9 is atomized liquid. The atomized liquid can better handle the harmful gas generated by the welding head 4 during welding, so that the harmful gas will not diffuse out, ensuring that the harmful gas generated by the welding head 4 during welding will not pollute the environment and cause harm to the human body.

[0063] When the water outlet pipe 9 where the conduit 13 is located is connected to the linkage hole 14, the liquid discharged from the water outlet pipe 9 can be ejected with stronger force under the action of the conduit 13; after the liquid is pressurized by the conduit 13, the sputtering liquid formed when the liquid contacts the steel casing has a wider diffusion range, thereby further expanding the contact area between the sputtering liquid and the steel casing, ensuring that the position where the steel casing is welded can be quickly cooled down under the action of the sputtering liquid, thereby improving the cooling quality and cooling efficiency.

[0064] In summary, by setting two different modes of the atomizing nozzle 12 and the conduit 13 and exchanging them back and forth, the welding quality is comprehensively improved and the welding effect is enhanced.

[0065] During the reciprocating motion, the linkage block 11 gradually communicates with the water outlet pipe 9 through the linkage hole 14, thereby being able to change the water inlet diameter of the water outlet pipe 9 to further enhance the force when the liquid is discharged, that is, the scope of liquid action is more comprehensive, the cooling effect is more significant, and the purification effect is more complete.

[0066] During the rotation of the long shaft 28, the long shaft 28 drives the water outlet pipe 9 to rotate through the belt 42, so that the atomizing nozzle 12 and the conduit 13 can both rotate under the interaction of the first gear 17 and the second gear 18. During the rotation of the atomizing nozzle 12 and the conduit 13, the atomized liquid and the liquid can be diffused over a large area, ensuring that the atomized liquid can contact the harmful gas more comprehensively and the contact area between the liquid and the steel casing is more sufficient, thereby further enhancing the purification effect and improving the cooling quality.

[0067] During the rotation of the water outlet pipe 9, the first gear 17 and the second gear 18 are meshed, so that the rotating shaft 15 can rotate. During the rotation of the rotating shaft 15, the rotating blades 16 rotate synchronously. During the rotation of the rotating blades 16, cold air can be output to the steel casing, increasing the cooling method, so that the steel casing can be quickly cooled down with the cooperation of liquid and cold air. At the same time, during the rotation of the fan blades 29, the effective distance of the atomized liquid can be further increased and the effective range of the atomized liquid can be expanded, further making the purification effect of the atomized liquid on harmful gases more significant, that is, shortening the purification time and improving the purification efficiency.

[0068] During the reciprocating motion of the linkage block 11, the first rack 40 moves synchronously. During the motion of the first rack 40, the third gear 41 rotates because the first rack 40 meshes with the third gear 41. During the rotation of the third gear 41, the screw 23 rotates synchronously. During the rotation of the screw 23, the fourth gear 44 rotates synchronously. During the rotation of the fourth gear 44, the second rack 43 can reciprocate along the length direction of the limit block 20 because the fourth gear 44 meshes with the second rack 43. During the motion of the second rack 43, the slider 21 moves synchronously. During the reciprocating motion of the slider 21, the arc block 22 moves synchronously.

[0069] During the movement of the arc block 22, the rubber tube 19 will be continuously deformed under the action of the arc block 22. During the deformation of the rubber tube 19, the diameter of the rubber tube 19 will be squeezed and reduced, thereby increasing the pressure in the rubber tube 19, that is, the liquid sprayed from the rubber tube 19 can increase the effective distance of the liquid after the rubber tube 19 is deformed, and enhance the force of the liquid when it is sprayed. During the period when the diameter of the rubber tube 19 gradually returns to the initial state, the effective distance of the liquid also gradually returns to the initial state. Therefore, through the deformation of the rubber tube 19, the force of the liquid when it is sprayed can be continuously adjusted, thereby ensuring that the atomized liquid can more thoroughly treat the harmful gas and the liquid can more fully cool the steel casing, that is, the effect of the atomized liquid and the liquid is comprehensively enhanced.

[0070] During the rotation of the screw 23, the nut seat 25 can reciprocate along the length direction of the guide rod 24. During the movement of the nut seat 25, the sponge block 26 moves synchronously. During the movement of the sponge block 26, the water remaining on the steel casing will be absorbed by the sponge block 26, making the sponge block 26 moist. On the one hand, it can lock the moisture and prolong the time for the water to act on the surface of the steel casing, ensuring that the process of heat exchange between the water and the steel casing can be fully carried out, enhancing the cooling effect on the weld, so that the temperature of the weld can be quickly reduced; on the other hand, it can also clean the surface of the weld and remove the dust generated by welding, thereby ensuring that the dust will not adhere to the steel casing and improving the cleanliness of the surface of the steel casing.

[0071] During the rotation of the long shaft 28, the fan blades 29 rotate synchronously. Through the rotation of the fan blades 29, all the harmful gases generated by welding can be sucked into the air guide cover 27, and then discharged into the purification box 5 along the exhaust pipe, so that the harmful gases are purified under the treatment of the liquid, ensuring that when the harmful gases are discharged again, there is no pollution to the environment and no harm to the human body.

[0072] During the reciprocating motion of the movable block 32, the horizontal block 34 moves synchronously. During the motion of the horizontal block 34, the vertical block 35 moves synchronously. Through the reciprocating motion of the vertical block 35, the vertical block 35 can fully stir the liquid and harmful gas in the purification box 5, so that the harmful gas and the liquid are mixed more evenly and thoroughly, shortening the processing time of the harmful gas, enhancing the processing effect of the harmful gas, and improving the processing efficiency of the harmful gas.
