Description

Technical Field

[0001] The invention belongs to the technical field of steel structure welding, in particular to a steel structure welding device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. Steel structure welding is a common connection method and is widely used in buildings, bridges, ships and other fields. It has the advantages of high strength, good seismic resistance and long service life. Therefore, it has been widely used in modern engineering. Among them, steel plate welding in steel structure occupies a vital position in the field.

A protective cover is installed on the top of the device body, a fixed plate is installed on the inner wall of the device body, a slide rail seat is symmetrically installed on the top of the fixed plate, and a driving slider is embedded on the top of the slide rail seat; the positioning clamping plate is driven by the telescopic rod to clamp the outer side of the stainless steel flat plate, which reduces labor intensity and is suitable for the processing requirements of stainless steel flat plates of different sizes and specifications. The protective cover seals the welding process, and the fan runs through the smoke hood to absorb the welding smoke generated during the welding process to reduce pollution.

[0004] In the above technical scheme, although the versatility of welding can be improved and the pollution of welding smoke can be reduced, the protective hood absorbs the welding smoke, which causes the inner wall of the protective hood to easily breed more dirt.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Combination Figure 1 and Figure 2As shown, a steel structure welding device comprises a base 1, a mounting seat 2 is fixedly connected to the front and back sides of the base 1, a threaded rod 3 is rotatably connected to the inner cavity of the base 1, a welding frame 4 is fixedly connected to the top of the base 1 above the mounting seat 2, a processing box 6 is fixedly connected between the inner side walls of the two mounting seats 2, a welding gun 5 is installed at the lower side of the welding frame 4 close to the processing box 6, the bottom end of the welding gun 5 has a welding head, the welding gun 5 is externally connected to a welding machine through a connecting pipe, a hoop 7 is fixedly connected to the outside of the welding gun 5, a driving assembly is transferred to the outside of the threaded rod 3, a clamping assembly is installed on the top of the mounting seat 2, the clamping assembly is used to clamp and fix the steel plate workpiece, a welding smoke prevention assembly is installed inside the processing box 6, the welding smoke prevention assembly is used to seal the smoke during the welding of the steel plate workpiece; when working, the equipment is applied to the workshop scene of the welding process of the steel structure factory, the purpose is to weld two steel plate workpieces together, expand the coverage of the steel plate workpiece, and facilitate the subsequent welding. The steel plate workpiece is welded with the steel section to form a steel frame. First, the steel plate workpiece is placed on the clamping assembly, and then the welding machine and the driving assembly are started through the control program. The driving assembly drives the threaded rod 3 to rotate. When the threaded rod 3 rotates, the internal thread rubs against the driving assembly. Under the action of the thread cooperation of the threaded rod 3, the driving assembly is displaced. After the displacement, the driving assembly drives the clamping assembly to move, and the clamping assembly generates a force for moving in opposite directions. Under the action of the clamping force of the opposite movements, the steel plate workpiece is clamped and squeezed tightly. At the same time, when the driving assembly drives the clamping assembly to move, the movement of the clamping assembly gradually pushes the steel plate workpiece away, and the steel plate workpiece is displaced. At this time, the welding head at the end of the welding gun 5 welds the moving steel plate workpiece, and finally the steel plate workpiece passes through the welding frame 4 and flows out, which solves the problem that the steel plate workpiece is too long and affects the clamping and fixation, so as to prevent the quality of subsequent welding from being affected. It should be noted that the connecting pipe and the welding machine are prior art.

[0023] After the clamping component is processed, the welding smoke generated by the welding of the welding gun 5 and the steel plate workpiece is difficult to handle, causing the welding smoke to rise and spread around. After the diffusion, it will contaminate the clamping component outside the processing box 6, causing the clamping component equipment to turn black, and the aesthetics and cleanliness will decrease. In addition, the welding smoke has a high temperature and meets the small water droplets in the air, liquefies to form sewage and falls on the steel plate workpiece, which may contaminate the welded steel plate workpiece, resulting in poor welding quality and dirt problems. Because the welding gun 5 needs to be pressed down and contacted with the steel plate workpiece by the program during welding, the ring hoop 7 is driven to move when the welding gun 5 is pressed down, and the ring hoop 7 is gradually squeezed downward with the welding smoke protection component. The welding smoke protection component is squeezed and deformed and moves. After the movement, the welding smoke protection component gradually moves toward the direction of the processing box 6, and by surrounding the outside of the processing box 6, the scope of welding smoke pollution is reduced, and the welding smoke is prevented from passing through the processing box 6 to contaminate the external clamping component, which is convenient for improving the cleanliness of the equipment and ensuring that the welding quality of the steel plate workpiece is not affected.

[0024] Combination Figures 3 to 5The drive assembly includes a servo motor 31 installed at the end of the threaded rod 3, the output end of the servo motor 31 is connected to the threaded rod 3, the outer surface of the threaded rod 3 is connected to a slide seat 32, the top of the slide seat 32 is connected to a guide plate 33, and a bolt column 34 is fixedly connected to the upper end of the guide plate 33 away from the slide seat 32; the slide seat 32 is a "T"-shaped structure, the threaded rod 3 passes through the interior of the slide seat 32 and is connected to the servo motor 31, the top of the bolt column 34 is installed with an anti-drop sheet, and the top of the base 1 is provided with a track compatible with the slide seat 32; during operation, since the steel plate workpiece needs to be fixed before welding to ensure the accuracy of welding, the force driven by the threaded rod 3 needs to be converted during fixing so that the driving force acts on the clamping assembly to complete the fixing, using the embodiment of the present invention, the servo motor 31 is started to work through the control program, the servo motor 31 is energized to drive the threaded rod 3 to rotate, the threaded rod 3 rotates and squeezes the internal texture of the slide seat 32, and the slide The seat 32 is acted upon by the thread to slide along the track at the top of the base 1. When the servo motor 31 is not started, the distance of the slide 32 remains unchanged when it is not twisted by the threaded rod 3. The slide 32 pulls the guide plate 33 with the same force, and the guide plate 33 does not change its position. When the slide 32 is displaced by the twisting action of the threaded rod 3, the slide 32 will drive the guide plate 33 and the bolt column 34 to move synchronously, the displacement distance of the slide 32 changes, and the traction force of the slide 32 on the guide plate 33 increases. At this time, the slide 32 drives the guide plate 33 to change its position, and the guide plate 33 moves from the outside to the direction close to the processing box 6. The guide plate 33 drives the bolt column 34 to move synchronously, and the bolt column 34 is connected to the clamping assembly. After the drive of the threaded rod 3 and the displacement of the bolt column 34, the clamping assembly is driven, which ensures that the equipment has the function of synchronous movement, reduces unnecessary steps required for operation, achieves the effect of synchronous clamping during direct welding, and improves production efficiency.

[0025] Combination Figures 6 to 8As shown, the clamping assembly includes a horizontal plate 21 installed on the top of the mounting seat 2, the bottom of the horizontal plate 21 is located at the inner wall of the mounting seat 2 and is fixedly connected to a magnetic plate 22, the inner wall of the magnetic plate 22 is slidably connected to a magnetic plate 23, the bottom end of the magnetic plate 23 is fixedly connected to a clamp 24, a rotating bead is installed at the bottom of the clamp 24, a bottom leg 25 is fixedly connected to the middle of the bottom of the clamp 24, a guide rail 26 is fixedly connected between the two magnetic plates 22, a placement box 27 is fixedly connected to the middle of the top of the guide rail 26, a conveyor belt is arranged at the bottom of the placement box 27, and the conveyor belt is connected to the slide seat 32 by a belt type; the top of the placement box 27 is fixedly connected to the bottom of the processing box 6, and slide grooves are opened on both sides of the guide rail 26, and the slide grooves of the guide rail 26 are adapted to the bottom legs 25; the placement box 27 The sides close to the magnetic plate 23 are provided with through grooves corresponding to the clamps 24. The magnetic plate 1 22 is made of soft magnetic material. The top of the clamp 24 is connected to the bolt 34, and the bottom leg 25 is slidably connected to the slide groove of the guide rail 26. During operation, it is necessary to fix the steel plate workpiece so that the welding of the steel plate workpiece does not deviate to ensure the welding accuracy. However, due to the different specifications and lengths of the steel plate workpieces, some steel plate workpieces are too long during the fixing process, and the excess parts will interfere with the fixing effect. It is often necessary to unify the specifications before welding at the designated position. The universal performance is not high and there are certain limitations. Using the embodiment of the present invention, firstly, the corresponding threshold value is formulated through the control program, and then the steel plate The workpiece is placed on the conveyor belt from the through slot on the side of the placement box 27, and the bolt 34 is driven by the guide plate 33 to move. The clamp 24 connected to the top of the bolt 34 is affected and moves synchronously. When the bolt 34 moves in the direction close to the placement box 27, the clamp 24 gradually moves in the direction close to the placement box 27. The displacement of the clamp 24 drives the magnetic suction plate 23 and the bottom leg 25 to work. The displacement of the magnetic suction plate 23 decomposes the force adsorbed on the magnetic suction plate 1 22, and the magnetic suction plate 23 is separated from the side wall of the magnetic suction plate 1 22. The bottom leg 25 moves along the slide groove of the guide rail 26, and finally the two clamps 24 are driven to be squeezed close to the position of the steel plate workpiece. Under the action of the opposite squeezing, the steel plate workpiece in the middle of the placement box 27 is placed. The parts are clamped and fixed, so that the steel plate workpiece can be fixed according to the preset clamping force threshold, which improves the versatility of clamping. At the same time, when the slide 32 drives the two clamps 24 to clamp the steel plate workpiece, the slide 32 moves a certain distance, and the slide 32 interacts with the conveyor belt. The conveyor belt will transport the steel plate workpiece, and the steel plate workpiece moves toward the welding frame 4. When moving, it passes through the welding head position at the bottom of the welding gun 5. Through the continuous movement of the steel plate workpiece, it is welded with the welding head at the bottom of the welding gun 5, thereby completing the welding process of the two steel plate workpieces and improving the convenience of use. It should be noted that the rotating ball at the bottom of the clamp 24 plays a role in facilitating the reinforcement of the steel plate workpiece without hindering the transportation of the steel plate workpiece.

[0026] Combination Figures 8 to 10 , Fig.12The welding smoke prevention component includes a folding plate 61 installed inside the processing box 6, and a rotating rod 62 is rotatably connected inside the folding plate 61. The rotating rod 62 is composed of a rod and a block. A shielding plate 66 is fixed to the outside of the block of the rotating rod 62. A push rod 2 65 is fixed to the middle of the inner wall of the shielding plate 66, and a push rod 1 64 is fixed to the top of the push rod 2 65. The top of the push rod 1 64 is rotatably connected to an inclined block 63. A traction rope 67 is fixed to the end of the push rod 2 65 away from the shielding plate 66, and a pressing plate 68 is fixed to the end of the traction rope 67. A rubber pad 69 is clamped at the inner cavity of the pressing plate 68. The diameter of the hoop 7 is larger than the diameter of the middle part of the rubber pad 69. A plurality of top columns 60 are fixed between the top of the pressing plate 68 and the inner top wall of the processing box 6. The folding plate 61 and the rotating rod 6 2, there is reserved space between the blocks for turning over the shielding plate 66, the traction rope 67 passes through the pressure plate 68 and is connected to the rubber cushion layer 69; the top of the inclined block 63 is connected to the inner top wall of the processing box 6, and the inclined block 63 is composed of a semicircular block and a rod accessory. The outside of the rod accessory of the inclined block 63 is rotatably connected to the push rod 64, and a magnetic strip is installed at the bottom of the shielding plate 66, and a blocking component is installed at the bottom of the pressure plate 68. The blocking component is used to clean the position after the welding smoke rises; when working, in the process of welding, the steel plate workpiece contacts with the welding gun 5 to generate high temperature and form welding smoke. The welding smoke spreads upward or around. If the welding smoke is not sealed, the diffusion range is large, which will cause the surrounding parts to be contaminated. When a batch of dirt is caused, if the processing box 6 is sealed, it is inconvenient to clean the inside of the processing box 6. When it is necessary to facilitate cleaning and prevent the welding smoke pollution from expanding, the embodiment of the present invention is used to control the welding gun 5 to move downward to weld the steel plate workpiece. When the welding gun 5 is pressed down, the hoop 7 is driven to move. The welding gun 5 and the hoop 7 pass through the inside of the processing box 6. The welding gun 5 passes through the middle of the rubber cushion layer 69. However, since the diameter of the hoop 7 is larger than the diameter of the middle of the rubber cushion layer 69, the hoop 7 will collide with the rubber cushion layer 69 when it is pressed down. The rubber cushion layer 69 is squeezed downward and deformed downward. The deformation of the rubber cushion layer 69 tightens the traction rope 67 to move, and the traction rope 67 gradually The push rod 2 65 is driven to work, and the push rod 2 65 drives the baffle plate 66 and the push rod 1 64 to move. The push rod 1 64 rotates along the outer periphery of the rod fitting of the inclined block 63, and the baffle plate 66 is pulled to move from the outside to the inside toward the direction of the steel plate workpiece. The rotating rod 62 is affected by the baffle plate 66 and rotates. The baffle plate 66 covers the two sides of the processing box 6 to seal the two sides of the processing box 6 to prevent the welding smoke from leaking from the side of the processing box 6. Finally, the magnetic strip of the baffle plate 66 is adsorbed with the top side of the placement box 27 to ensure that the internal welding range is reduced, ensure the cleanliness of the overall equipment, avoid spreading outward and causing dirt, so that the side wall of the processing box 6 is easy to clean after opening, and does not affect the sealing treatment of the welding smoke.

[0027] Combination Figure 10 to Figure 11The blocking assembly includes two vertical bars 665 installed at the bottom of the pressure plate 68, the bottom ends of the two vertical bars 665 are fixedly connected to a shell 664, and a docking plate 663 is slidably connected to the inner cavity of the shell 664. A middle guide rod 662 is fixedly connected to the side of the docking plate 663 close to the shielding plate 66, and a fixing frame 661 is penetrated and connected to the outside of the end of the middle guide rod 662; the fixing frame 661 is fixedly connected to the inner wall of the shielding plate 66, the interior of the shell 664 is hollow, and the bottom surface of the shell 664 is honeycomb-shaped, activated carbon is installed inside the shell 664, and the docking plate 663 penetrates the interior of the shell 664; when working, in the process of welding, the range of welding smoke is reduced due to the cooperation of the processing box 6 and the shielding plate 66, but the welding smoke itself has a high temperature. After the welding smoke temperature contacts with the water vapor in the air, it is easy to liquefy to produce small water droplets that adhere to the bottom end of the welding gun 5 or the bottom surface of the pressure plate 68. Over time The latter drips on the position of the steel plate workpiece, affecting the quality of the steel plate workpiece during normal welding. When the shielding plate 66 moves in the direction close to the steel plate workpiece, the shielding plate 66 will drive the fixing frame 661 to move, and the fixing frame 661 gradually contacts with the middle guide rod 662, and the fixing frame 661 hits the middle guide rod 662 to move, and the middle guide rod 662 pushes the docking plate 663 to move synchronously, and the docking plate 663 penetrates the internal displacement of the shell 664, and the docking plate 663 extends from the inside of the shell 664. The two shells 664 move toward the middle and dock at the periphery of the welding gun 5, and the bottom of the shell 664 gradually absorbs the floating welding smoke, and the activated carbon inside the shell 664 purifies the welding smoke, isolates the conditions required for liquefaction, prevents the welding quality from being disturbed, and ensures the cleanliness of the steel plate workpiece; it should be noted that the above equipment can withstand the high temperature generated during welding.

[0028] Working principle: since the steel plate workpiece needs to be fixed before welding to ensure the accuracy of welding, but the force driven by the threaded rod 3 needs to be converted during fixing so that the driving force acts on the clamping assembly to complete the fixing, using the embodiment of the present invention, the servo motor 31 is started by the control program, the servo motor 31 is energized to drive the threaded rod 3 to rotate, the threaded rod 3 rotates and is squeezed against the internal texture of the slide 32, the slide 32 is slid along the track at the top of the base 1 by the thread, when the servo motor 31 is not started, the distance of the slide 32 does not change when it is not twisted by the threaded rod 3, the slide 32 pulls the guide plate 33 with the same force, the guide plate 33 does not change position, and the slide When 32 is displaced by the twisting action of the threaded rod 3, the slide 32 will drive the guide plate 33 and the bolt 34 to move synchronously, the displacement distance of the slide 32 changes, the traction force of the slide 32 on the guide plate 33 increases, and the slide 32 drives the guide plate 33 to change its position at this time, and the guide plate 33 moves from the outside to the direction close to the processing box 6, and the guide plate 33 drives the bolt 34 to move synchronously, and the bolt 34 is connected to the clamping assembly. Through the drive of the threaded rod 3 and the displacement of the bolt 34, the clamping assembly is driven, which ensures that the equipment has the function of synchronous movement, reduces unnecessary steps required for operation, achieves the effect of synchronous clamping during direct welding, and improves production efficiency.

[0029] Since the steel plate workpiece needs to be fixed so that the welding of the steel plate workpiece does not deviate to ensure the welding accuracy, but due to the different specifications and lengths of the steel plate workpieces, some steel plate workpieces are too long during the fixing process, and the excess part will interfere with the fixing effect. It is often necessary to unify the specifications before welding at the designated position. The universal performance is not high and there are certain limitations. Using the embodiment of the present invention, firstly, the corresponding threshold value is set through the control program, and then the steel plate workpiece is placed in the middle from the through slot on the side of the placement box 27. The bolt 34 is driven by the guide plate 33 to move, and the clamp 24 connected to the top of the bolt 34 is affected and moves synchronously. When the bolt column 34 moves toward the placement box 27, the clamp 24 gradually moves toward the placement box 27, and the displacement of the clamp 24 drives the magnetic plate 23 and the bottom leg 25 to work. The displacement of the magnetic plate 23 decomposes the force adsorbed on the magnetic plate 1 22, and the magnetic plate 23 separates from the side wall of the magnetic plate 1 22. The bottom leg 25 moves along the slide groove of the guide rail 26, and finally the two clamps 24 are driven to be squeezed toward the position close to the steel plate workpiece. Under the action of the mutual squeezing, the steel plate workpiece in the middle of the placement box 27 is clamped and fixed, so that the steel plate workpiece can be fixed according to the preset clamping force threshold, thereby improving the versatility of clamping and the convenience of use.

[0030] During the welding process, the steel plate workpiece contacts the welding gun 5 to generate high temperature and form welding smoke. The welding smoke spreads upward or around. If the welding smoke is not sealed, the diffusion range is large, which will cause the surrounding parts to be contaminated in a larger range and cause batch contamination problems. If the processing box 6 is sealed, it is inconvenient to clean the inside of the processing box 6. When it is necessary to facilitate cleaning and prevent the welding smoke from being contaminated in a larger range, the embodiment of the present invention is used to control the welding gun 5 to move downward to weld the steel plate workpiece. When the welding gun 5 is pressed down, the hoop 7 is driven to move. The welding gun 5 and the hoop 7 pass through the interior of the processing box 6. The welding gun 5 passes through the middle of the rubber pad 69. However, since the diameter of the hoop 7 is larger than the diameter of the middle of the rubber pad 69, the hoop 7 will collide with the rubber pad 69 when it is pressed down, and the rubber pad 69 is squeezed downward. The rubber cushion layer 69 deforms downward, and the deformation of the rubber cushion layer 69 tightens the traction rope 67 to move. The traction rope 67 gradually drives the push rod 2 65 to work, and the push rod 2 65 drives the baffle plate 66 and the push rod 1 64 to move. The push rod 1 64 rotates along the outer periphery of the rod fitting of the inclined block 63, and the baffle plate 66 is pulled from the outside to the inside toward the direction of the steel plate workpiece. The rotating rod 62 is affected by the baffle plate 66 and rotates. The baffle plate 66 covers the two sides of the processing box 6 to seal the two sides of the processing box 6 to prevent the problem of welding smoke leakage from the side of the processing box 6. Finally, the magnetic strip of the baffle plate 66 is adsorbed with the top side of the placement box 27 to ensure that the internal welding range is reduced, ensure the cleanliness of the overall equipment, and avoid spreading outward to cause dirt, so that the side wall of the processing box 6 is easy to clean after opening, and does not affect the sealing treatment of the welding smoke.

[0031] During the welding process, the range of welding smoke is reduced due to the cooperation between the processing box 6 and the shielding plate 66. However, the welding smoke itself has a high temperature. After the welding smoke temperature contacts with the water vapor in the air, it is easy to liquefy to produce small water droplets that adhere to the bottom end of the welding gun 5 or the bottom surface of the pressure plate 68. After a long time, it drips on the position of the steel plate workpiece, affecting the quality of the steel plate workpiece during normal welding. When the shielding plate 66 moves in the direction close to the steel plate workpiece using the embodiment of the present invention, the shielding plate 66 will drive the fixing frame 661 to move, and the fixing frame 661 gradually contacts with the middle guide rod 662, and the fixing frame 6 61 hits the middle guide rod 662 to move, and the middle guide rod 662 pushes the docking plate 663 to move synchronously. The docking plate 663 penetrates the internal displacement of the shell 664, and the docking plate 663 extends from the inside of the shell 664. The two shells 664 move toward the middle and dock at the outer periphery of the welding gun 5. The bottom of the shell 664 gradually absorbs the floating welding smoke, and the activated carbon inside the shell 664 purifies the welding smoke, isolates the conditions required for liquefaction, prevents the welding quality from being disturbed, and ensures the cleanliness of the steel plate workpiece; it should be noted that the above equipment can withstand the high temperature generated during welding.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
