Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and particularly relates to a steel structure welding equipment. Background Art

[0002] Welding, also known as fusion welding or brazing, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.

[0003] A steel structure is a structure composed 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 sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between components or parts.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0042] As Figures 1 to 10 shown, a steel structure welding device of the present invention includes: a machine table 1; a welding mechanism 3 for welding steel pipes; a fixing mechanism 2 for fixing steel pipes.

[0043] The fixing mechanism 2 includes: a fixing frame 21 fixedly installed on the machine table 1; a first chuck 22 movably installed on the fixing frame 21; a sliding frame 23 slidably installed on the fixing frame 21; a second chuck 24 fixedly installed on the sliding frame 23; a threaded rod 25 threadedly connected to the sliding frame 23; a first power source 26 for driving the threaded rod 25 to rotate, and the first power source 26 is fixedly installed on the fixing frame 21.

[0044] Before welding, it is necessary to fix two steel pipes separately, that is, one steel pipe is clamped and fixed by the first chuck 22, and the other steel pipe is clamped and fixed by the second chuck 24. Both the first chuck 22 and the second chuck 24 are common electric three-jaw chucks and are driven by motors to rotate, and then the fixed steel pipes can be driven to rotate, and in cooperation with the welding mechanism 3, the two steel pipes can be circumferentially welded, improving the welding efficiency.

[0045] When welding the steel pipes, start the first power source 26 to drive the threaded rod 25 to rotate. The threaded rod 25 drives the sliding frame 23 to slide on the fixing frame 21, thereby driving the second chuck 24 to move, so that the welding ends of the two steel pipes are closely abutted, preparing for subsequent welding.

[0046] It is supplemented here that the power source 26 is preferably a motor.

[0047] The welding mechanism 3 includes: a laser welding head 31; a grinding machine 32; a robot 33 that drives the laser welding head 31 and the grinding machine 32 to move, and the robot 33 is fixedly installed on the machine table 1; an adjustment assembly 34 for adjusting the positions of the laser welding head 31 and the grinding machine 32; the adjustment assembly 34 includes: a mounting shell 341 installed on the robot 33; an interlocking gear 342 rotatably installed in the mounting shell 341; an interlocking rack 343 meshed and connected with the interlocking gear 342, and there are two interlocking racks 343, symmetrically arranged on both sides of the interlocking gear 342; a power source 344 for driving the interlocking rack 343 to move; the power source 344 is fixedly installed in the mounting shell 341, and the telescopic end of the power source 344 is fixedly connected to any one of the interlocking racks 343; a limiting member 345 for limiting the interlocking rack 343; both the laser welding head 31 and the grinding machine 32 are fixedly connected to the interlocking rack 343; the bottom end of one interlocking rack 343 is fixedly connected to the laser welding head 31, and the bottom end of the other interlocking rack 343 is fixedly connected to the grinding machine 32.

[0048] Since the surface to be welded of the steel pipe is prone to oxide scale, rust, oil stain and unevenness, it is easy to cause welding interruption or repeated welding, affecting the welding efficiency.

[0049] In the present invention, by providing the grinding machine 32, the surface to be welded of the steel pipe can be ground before welding, effectively removing oxide scale, rust, oil stain and unevenness, significantly improving the surface roughness, creating good physical conditions for subsequent welding. This grinding pretreatment ensures the high cleanliness and flatness of the welding area and improves the welding efficiency.

[0050] Before grinding, the surfaces to be welded of the two steel pipes are not butted. After grinding is completed, the fixing mechanism 2 is started to butt the surfaces to be welded of the two steel pipes, so that the surfaces to be welded of the two steel pipes are closely abutted, and then the laser welding head 31 is started for welding.

[0051] It is supplemented here that the power source 344 is preferably a cylinder.

[0052] The limiting member 345 includes: a slide rail 3451 fixedly installed inside the installation shell 341; a slider 3452 slidably installed on the slide rail 3451; a chute opened inside the installation shell 341; a slide bar 3453 slidably installed in the chute; both the slider 3452 and the slide bar 3453 are fixedly connected to the linkage rack 343; when the linkage rack 343 moves, it can drive the slider 3452 to slide on the slide rail 3451 and at the same time drive the slide bar 3453 to slide in the chute. Through the setting of the limiting member 345, the linkage rack 343 can be double-limited, thus ensuring the stability of the linkage rack 343 during movement, and further ensuring the stability of the laser welding head 31 and the grinding machine 32 during movement.

[0053] When adjusting the positions of the laser welding head 31 and the grinding machine 32, when the power source two 344 is started to drive the adjacent linkage rack 343 to move downward, the linkage rack 343 drives the linkage gear 342 to rotate, thereby driving the other linkage rack 343 to move upward. When the power source two 344 drives the adjacent linkage rack 343 to move upward, the linkage rack 343 drives the linkage gear 342 to rotate in the reverse direction, thereby driving the other linkage rack 343 to move downward.

[0054] Since the bottom end of one of the two linkage racks 343 is fixedly connected to the laser welding head 31, and the bottom end of the other linkage rack 343 is fixedly connected to the grinding machine 32; therefore, when the laser welding head 31 moves downward, the grinding machine 32 moves upward; similarly, when the laser welding head 31 moves upward, the grinding machine 32 moves downward.

[0055] When grinding the surface of the steel pipe to be welded, the grinding machine 32 moves downward. The grinding machine 32 mainly consists of a motor and a grinding cylinder. The robot 33 drives the grinding machine 32 to move to the required position, and the steel pipe is rotated by the fixing mechanism 2, so as to realize the grinding of the surface of the steel pipe to be welded.

[0056] In the present invention, through the setting of the adjusting assembly 34, the positions of the laser welding head 31 and the grinding machine 32 can be adjusted. On the one hand, the surface of the steel pipe to be welded can be ground before welding, effectively removing oxide scale, rust, oil stain and unevenness, significantly improving the surface roughness, and creating good physical conditions for subsequent welding. On the other hand, the surface of the steel pipe to be welded after grinding can be welded, improving the welding efficiency and welding effect.

[0057] The welding mechanism 3 further includes a dust removal assembly 35 for collecting dust during grinding; the dust removal assembly 35 includes a collection box 351 fixedly installed on the machine table 1, a pump body 352; a first filter screen 353 fixedly installed in the collection box 351; a first air jet member 354 fixedly installed on the laser welding head 31; a second air jet member 355 fixedly installed on the grinding machine 32; the collection box 351 is communicated with the pump body 352 through an air delivery pipe 358; the first air jet member 354 includes a first annular pipe 3541 fixedly installed on the laser welding head 31; a first nozzle 3542 communicated with the first annular pipe 3541; the second air jet member 355 includes a second annular pipe 3551 fixedly installed on the grinding machine 32; a second nozzle 3552 communicated with the second annular pipe 3551.

[0058] When grinding the steel pipe, dust will be generated, which is likely to pollute the environment. Therefore, it is necessary to collect the dust to avoid polluting the environment.

[0059] When the grinding machine 32 grinds the steel pipe, the pump body 352 is started. The pump body 352 sucks out the air in the collection box 351 through the air delivery pipe 358, causing a negative pressure in the collection box 351. As a result, the outside air flows into the collection box 351, and then the dust generated during grinding enters the collection box 351 with the air flow for collection. Through the setting of the first filter screen 353, the air entering the collection box 351 can be filtered, so that the dust remains on the air inlet side of the first filter screen 353, and the filtered air is discharged through the pump body 352.

[0060] In addition, during the welding process of the steel pipe, welding slag and welding fumes will be generated. During this process, the welding slag and welding fumes enter the collection box 351 with the air flow, so that the welding slag and welding fumes can be filtered, further avoiding polluting the environment.

[0061] The dust removal assembly 35 further includes a switching unit 356 for switching the gas flow direction discharged from the pump body 352; the switching unit 356 includes a gas collecting pipe 3569 fixedly installed on the installation shell 341; a threaded shaft 3561 coaxially connected to the linkage gear 342, the threaded shaft 3561 is rotatably installed on the installation shell 341; a threaded pipe 3562 threadedly connected to the threaded shaft 3561; a piston 3563 fixedly installed at the end of the threaded pipe 3562, the piston 3563 is slidably installed in the gas collecting pipe 3569; a limiting pipe 3564 sleeved on the threaded pipe 3562, the limiting pipe 3564 is fixedly connected to the installation shell 341; a limiting groove opened in the limiting pipe 3564; a limiting strip 3565 slidably installed in the limiting groove; the limiting strip 3565 is fixedly connected to the threaded pipe 3562; the gas collecting pipe 3569 is communicated with the pump body 352 through an air inlet pipe 3566, the gas collecting pipe 3569 is communicated with the first annular pipe 3541 through an air outlet pipe 3567, and the gas collecting pipe 3569 is communicated with the second annular pipe 3551 through an air outlet pipe 3568.

[0062] When the grinding machine 32 moves downward, that is, the second power source 344 drives the adjacent linkage rack 343 to move downward. At this time, the linkage gear 342 can be driven to rotate, the linkage gear 342 drives the threaded shaft 3561 to rotate, the threaded shaft 3561 drives the threaded pipe 3562 to move. Under the limiting action of the limiting pipe 3564 and the limiting strip 3565, the threaded pipe 3562 moves along the axial direction of the threaded shaft 3561 and drives the piston 3563 to slide in the gas collecting pipe 3569 towards the air inlet end of the air outlet pipe 3568. When the grinding machine 32 moves downward to the required position, the piston 3563 is close to the air inlet end of the air outlet pipe 3568, so as to separate the air inlet end of the air outlet pipe 3568 from the air outlet end of the air inlet pipe 3566;

[0063] At this time, the pump body 352 transports the filtered gas to the gas collecting pipe 3569 through the air inlet pipe 3566, passes through the air outlet pipe 3567 and the first annular pipe 3541 in sequence, and sprays out from the first nozzle 3542. On the one hand, the dust on the surface of the grinding cylinder can be blown off to clean the grinding cylinder. On the other hand, it blows on the grinding area, and the dust at the grinding area can be blown off to clean the grinding area, and at the same time, it plays a role in blowing air and cooling the grinding area.

[0064] When the laser welding head 31 moves downward, that is, the power source two 344 drives the adjacent linkage rack 343 to move upward. At this time, the linkage gear 342 can be driven to rotate reversely. The linkage gear 342 drives the threaded shaft 3561 to rotate reversely, and the threaded shaft 3561 drives the threaded tube 3562 to move. Under the limiting action of the limiting tube 3564 and the limiting strip 3565, the threaded tube 3562 moves along the axial direction of the threaded shaft 3561 and drives the piston 3563 to slide towards the intake end of the first air outlet pipe 3567 in the air collecting pipe 3569. When the laser welding head 31 moves downward to the required position, the piston 3563 approaches the intake end of the first air outlet pipe 3567, thereby separating the air outlet end of the intake pipe 3566 from the intake end of the first air outlet pipe 3567;

[0065] At this time, the pump body 352 conveys the filtered gas to the air collecting pipe 3569 through the intake pipe 3566, passes through the second air outlet pipe 3568 and the second annular pipe 3551 in sequence, and sprays out from the second nozzle 3552. On the one hand, it can blow off the welding slag at the welding position to clean the welding position. On the other hand, when blowing on the surface of the laser welding head 31, it can blow off the dust on the surface of the laser welding head 31 to clean the laser welding head 31, and at the same time play a role in blowing air to cool the welding position.

[0066] As can be seen from the above, when the filtered gas is sprayed out through the first nozzle 3542, the dust generated during grinding can be cleaned. When the filtered gas is sprayed out through the second nozzle 3552, the welding slag generated during welding can be cleaned. The dust and welding slag fall into the collection box 351. At the same time, a negative pressure is generated in the collection box 351, which can quickly collect the dust and welding slag and improve the collection effect of the dust and welding slag.

[0067] The dust removal component 35 further includes a cleaning unit 357 for cleaning the first filter net 353; the cleaning unit 357 includes a movable pipe 3571 rotatably installed on the first filter net 353; an installation sleeve 3572 sleeved on the movable pipe 3571, and a sealing ring is fixedly installed on the inner wall of the installation sleeve 3572. When the installation sleeve 3572 is sleeved on the movable pipe 3571, the sealing ring improves the tightness between the installation sleeve 3572 and the movable pipe 3571; a collection pipe 3574 fixedly installed on the installation sleeve 3572; a second filter net 3576 fixedly installed in the collection pipe 3574, and the second filter net 3576 is spherical; a collection opening 3575 opened on the collection pipe 3574, and a plurality of collection openings 3575 are opened and arranged linearly; a guide pipe 3578 connecting the movable pipe 3571 and the air delivery pipe 358, and the air inlet end of the air delivery pipe 358 is rotatably connected to the movable pipe 3571; a connecting pipe 3577 connecting the collection pipe 3574 and the installation sleeve 3572, a through hole matching the connecting pipe 3577 is opened on the installation sleeve 3572, a third filter net is fixedly installed in the through hole, and the through hole is aligned with the corresponding connecting pipe 3577; a positioning block 3573 fixedly installed at the end of the movable pipe 3571, the positioning block 3573 is a rectangular block, and a positioning groove matching the positioning block 3573 is opened on the inner wall of the installation sleeve 3572. When the installation sleeve 3572 is installed on the movable pipe 3571, when the positioning block 3573 is completely inserted into the positioning groove, the connecting pipe 3577 is completely aligned with the through hole; a power member 3579 for driving the collection pipe 3574 to rotate.

[0068] When the pump body 352 is started, the gas in the collection pipe 3574 sequentially enters the air delivery pipe 358 through the connecting pipe 3577, the through hole, the movable pipe 3571, and the guide pipe 3578, so that a negative pressure is formed in the collection pipe 3574. At this time, suction is generated at the collection opening 3575, and the dust and welding slag on the surface of the first filter net 353 can be sucked into the collection pipe 3574 for collection, realizing the cleaning of the first filter net 353 and avoiding the blockage of the first filter net 353 by dust and welding slag, which affects the filtering effect.

[0069] Moreover, the collection opening 3575 is obliquely facing the top of the filter net, so as to facilitate sucking the dust and welding slag on the surface of the first filter net 353 into the collection pipe 3574 for collection.

[0070] Through the setting of the second filter net 3576, the air entering the collection pipe 3574 can be filtered, so that the dust and welding slag stay in the collection pipe 3574. Since the second filter net 3576 is spherical, it is not easy for the second filter net 3576 to accumulate dust and welding slag.

[0071] Meanwhile, start the power component 3579. The power component 3579 includes: a driven gear 35791 fixedly sleeved on the movable pipe 3571; a driving gear 35792 meshed with the driven gear 35791; a third power source 35793 that drives the driving gear 35792 to rotate. The third power source 35793 is fixedly installed in the collection box 351. That is, start the third power source 35793 to drive the driving gear 35792 to rotate. The driving gear 35792 drives the driven gear 35791 to rotate, thereby driving the movable pipe 3571 to rotate. The movable pipe 3571 drives the positioning block 3573 to rotate, and the positioning block 3573 drives the mounting sleeve 3572 to rotate, and then drives the collection pipe 3574 to rotate. By rotating the collection pipe 3574, the cleaning range of the collection pipe 3574 can be expanded, and the cleaning effect on the first filter screen 353 is improved.

[0072] When a certain amount of dust and welding slag are collected in the collection pipe 3574, pull the mounting sleeve 3572 to separate the mounting sleeve 3572 from the movable pipe 3571. At this time, it is convenient to take out the collection pipe 3574 from the collection box 351, and the dust and welding slag in the collection pipe 3574 can be removed. Then, install the collection pipe 3574 on the movable pipe 3571, so that the first filter screen 353 can be continuously cleaned.

[0073] When the collection pipe 3574 is taken out from the collection box 351, the first filter screen 353 can continue to collect dust and welding slag, thereby realizing the automatic cleaning of the first filter screen 353 without stopping the machine, without disassembling and cleaning the first filter screen 353, and facilitating the cleaning of the dust and welding slag collected in the collection pipe 3574, improving the welding efficiency.

[0074] It should be added here that the third power source 35793 is preferably a motor.

[0075] As an alternative solution of the present invention, a fan blade is also fixedly installed on the movable pipe 3571. When the movable pipe 3571 rotates, it can drive the fan blade to rotate, which can accelerate the flow of gas from the outside to the inside of the collection box 351 and improve the gas flow efficiency.

[0076] The standard parts used in the present invention can all be purchased from the market.
