TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure welding, in particular to a welding device for a steel pipe inner partition plate. BACKGROUND

[0002] In recent years, steel structure has been widely used in construction, industry and daily life. Steel structure has the characteristics of factory production of components, good seismic performance, low cost, recyclability and so on. Among them, steel pipe (including square pipe, rectangular pipe and round pipe) is one of the most commonly used steel components. In practical application, due to the need of structural stress, it is often necessary to set a transverse inner partition plate inside the steel pipe, and a full penetration butt joint must be used, for example, a box column (usually a square pipe or a rectangular pipe) used in a steel structure frame building must have a transverse inner partition plate with full penetration welding at the connecting joint with a steel beam. However, due to the limitation of the cross-sectional size of the general steel pipe, the welder cannot enter the inside of the steel pipe for welding, which leads to the need to use a very complex process to complete the welding of the inner partition plate, which is time-consuming and labor-intensive and increases the cost. SUMMARY

[0005] Further, the intelligent welding mechanical arm is a four-axis mechanical arm; the four-axis mechanical arm comprises a rotating block and three sections of mechanical arms; the rotating block can rotate around the central shaft pipe; the three sections of mechanical arms are connected through rotating shafts; the rotating shafts can change the angle to realize the extension and contraction of the mechanical arms; the four-axis mechanical arm is controlled through an intelligent system; optionally, the three sections of mechanical arms can be symmetrically arranged around the central shaft pipe; the three sections of mechanical arms are used to weld the weld between the steel pipe and the inner partition plate;

[0006] Further, the positioning suction cup is composed of a magnetic suction cup and a positioning support; the magnetic suction cup is an electrically controlled magnetic suction cup, which is used to hold the inner partition plate; the positioning support is composed of two equal-length rod members; the two equal-length rod members are symmetrically arranged around the central shaft pipe; the rod members are three sections of telescopic rods; the end of the three sections of telescopic rods away from the central shaft pipe is provided with a cylindrical rod, which is perpendicular to the telescopic rod; the three sections of telescopic rods can be driven by electricity to simultaneously and equidistantly contract in opposite directions, so that the center of the suction cup coincides with the center of the inner partition plate when the suction cup holds the inner partition plate, and the central shaft pipe is kept stable and centered in the steel pipe;

[0007] Further, the matching device comprises an inner partition plate auxiliary positioning seat; the inner partition plate auxiliary positioning seat is composed of a square positioning base plate, a fixed positioning corner and a movable magnetic positioning corner; the fixed positioning corner is located at a corner of the positioning base plate; the fixed positioning corner is composed of two mutually perpendicular steel plates and is perpendicular to the positioning base plate in pairs; the movable magnetic positioning corner comprises an angle steel and a magnetic block behind the angle steel; the movable magnetic positioning corner can be attracted to any position of the positioning base plate; the movable magnetic positioning corner is smaller than the fixed positioning corner; the movable magnetic positioning corner is in a diagonal direction with the fixed positioning corner;

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0018] The embodiments of the present application provide an operation mode for welding an inner partition plate of a box column by using an intelligent internal welding machine. The box column is a square tubular profile. The specific operation mode is as follows:

[0019] Step 1: first place the inner partition plate 10 on the square positioning base plate 11 of the inner partition plate auxiliary positioning seat, so that any corner of the inner partition plate is tightly pressed against the fixed positioning angle 13 in the inner partition plate auxiliary positioning seat, and the other corner (diagonal direction) is tightly pressed and held by the mobile magnetic positioning angle 12 in the inner partition plate auxiliary positioning seat;

[0020] Step 2: move the intelligent internal welding machine host to directly above the inner partition plate and slowly lower it down, with the magnetic force suction plate 2 at the lower end falling on the inner partition plate. The two support rods 3 of the motor-driven positioning suction plate are simultaneously and equally extended in opposite directions to tightly press against the fixed positioning angle 13 and the mobile magnetic positioning angle 12, respectively, to ensure that the magnetic force suction plate is coincident with the center of the inner partition plate, and the support rods are coincident with the diagonal direction of the inner partition plate. After positioning is completed, the magnetic force suction plate holds the inner partition plate by electric control, and after holding is completed, the mobile magnetic positioning angle in the inner partition plate auxiliary positioning seat releases the magnetism and is removed. The two positioning support rods are simultaneously and equally retracted. The inner partition plate is slowly lifted by the intelligent internal welding machine host;

[0021] Step 3: place the box column 9 vertically, and slowly lower the intelligent internal welding machine host with the inner partition plate through the suspension system to the inside of the box column; the distance measuring device ensures that the inner partition plate is placed at a specified position inside the box column; the two positioning supports 3 on the positioning suction plate are simultaneously and equally extended in opposite directions to tightly press against the opposite corners of the inner wall of the box column, to ensure that the central axis tube 1 is in the center position inside the box column and is fixed without shaking, and then the inner partition plate is in the horizontal center position inside the box column;

[0022] Step 4, the intelligent control system controls the mechanical arms 5, 6, 7 to adjust the angle and the telescopic distance according to the size of the box column, until the welding gun 8 clamped at the end can reach the optimal posture and distance of the weld between the inner baffle and the box column, then the three-section mechanical arms with the adjusted posture rotate around the central shaft pipe 1 through the rotating block 4, and drive the welding gun to rotate to weld the four horizontal welds of the inner baffle and the four walls of the box column; the two supporting rods of the positioning suction cup are simultaneously and equidistantly retracted for several seconds after the welding starts, the magnetic suction cup releases the inner baffle; the welding gun continues to complete the welding of the remaining weld between the inner baffle and the box column;

[0023] At the same time of welding, the air blowing system disperses the smoke generated in the welding process, and ensures that the lighting system and the visual monitoring system can work normally;

[0024] Similarly, the visual monitoring system starts to work at step 3, and tracks and observes the whole process of the intelligent inner welding machine in the box column, so as to control and correct at any time.

[0025] Step 5, the four welds between the inner baffle and the box column are welded, and the intelligent inner welding machine exits the box column through the suspension system.

[0026] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
