Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a square steel cage welding device. Background Technology

[0002] A steel cage is a cage-like structure made of steel bars, mainly used in the construction industry for pouring concrete to enhance the strength and bending resistance of concrete structures. Steel cages are also an indispensable structure in the modern construction field.

[0003] Existing square steel cages are mainly made of woven steel reinforcement materials, such as Figure 1 The diagram shows an existing reinforced steel cage structure. It includes several main reinforcing bars 101 arranged parallel to each other and several reinforcing bars 102 arranged at equal intervals around the main reinforcing bars 101. The main reinforcing bars 101 are arranged in a rectangular direction, and the reinforcing bars 102 are connected to the main reinforcing bars 101 by binding with thin steel wire to fix their positions. However, if the main reinforcing bars 101 and the reinforcing bars 102 are only bound with thin steel wire, the connection strength will inevitably be insufficient. When the square reinforced steel cage needs to be transported over long distances, it is easy to deform during transportation. Therefore, in order to improve the structural strength of the reinforced steel cage, it is generally necessary to weld the contact points of the main reinforcing bars 101 and the reinforcing bars 102. The traditional welding method is manual welding, but manual welding is not only labor-intensive but also inefficient. Therefore, it is necessary to propose a device that can automatically weld square reinforced steel cages.

[0004] Furthermore, after the rebar cage is welded, weld slag may protrude outwards from the weld points. When workers handle the rebar cage, they may sometimes accidentally get their hands pricked by the slag, causing inconvenience to their work. Therefore, we propose a square rebar cage welding device to effectively solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a square steel cage welding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A square rebar cage welding device includes a base and a welding mechanism. The top surface of the base is provided with a three-axis positioning mechanism for driving the welding mechanism to move. It also includes: two seat rings, each located on the top surface of the base and on the left and right sides of the welding mechanism. A rotating disk is rotatably connected inside each seat ring, and an operating opening is provided through the rotating disk for the rebar cage to pass through. A driving mechanism is mounted on the base and used to drive the rotating disk to rotate inside the seat rings. A cleaning frame is also included, mounted on the base. The cleaning frame has a rectangular structure, and wire brushes are rotatably connected to the four sides of the cleaning frame. The axial direction of the wire brushes is parallel to the corresponding sidewalls of the cleaning frame.

[0010] Optionally, a cleaning motor is also provided outside the cleaning frame, and the output shaft of the cleaning motor is coaxially connected to one of the steel wire roller brushes.

[0011] Optionally, the number of spray pipes corresponds one-to-one with the number of main reinforcing bars, and when the wire roller brush contacts the reinforcing bar, the nozzles at the end of the spray pipes are all aligned with the contact points between the corresponding main reinforcing bars and reinforcing bars. The spray pipes are also equipped with solenoid valves.

[0012] Optionally, lifting blocks are movably installed on both the left and right sides inside the cleaning frame. The lifting blocks are located between the gaps of two adjacent main reinforcing bars, and the bottom of the lifting blocks is arc-shaped. A conductive copper sheet is also attached to the bottom surface of the lifting blocks. When the conductive copper sheet contacts one reinforcing bar, the wire brush contacts the other reinforcing bar. A power supply is also provided on the base. The two conductive copper sheets are respectively connected to the positive and negative poles of the power supply through wires. The cleaning motor is set on the line where the negative pole of the power supply is connected to the conductive copper sheet.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Please refer to Figures 2-9A square rebar cage welding device includes a base 200 and a welding mechanism 300. A three-axis positioning mechanism 201 is provided on the top surface of the base 200 for driving the welding mechanism 300 to move. The invention also includes a seat ring 400 and a driving mechanism 600. There are two seat rings 400, both located on the top surface of the base 200 and on the left and right sides of the welding mechanism 300. The seat rings 400 have an annular structure. A rotating disk 500 is rotatably connected inside the seat ring 400. An operating port 501 is provided through the rotating disk 500 for the rebar cage to pass through. Specifically, several rollers 401 are rotatably connected to the inner ring wall of the seat ring 400. A rolling groove 502 is formed around the outer surface of the rotating disk 500 in a circumferential direction. The rollers 401 roll and fit against the rolling groove 502, thus allowing the rotating disk 500 to rotate freely inside the seat ring 400. Additionally, as... Figure 3 As shown, the seat ring 400 is composed of two semi-circular structures joined together, and the two semi-circles are fixed together by welding or bolts.

[0020] Additionally, the drive mechanism 600 is mounted on the base 200 and is used to drive the rotating disk 500 to rotate within the seat ring 400; specifically, the drive mechanism 600 includes a mounting base 601, a drive motor 602, and a drive gear 603, such as... Figure 2 As shown, the mounting base 601 is fixedly mounted on the base 200, the drive motor 602 is fixedly mounted on the mounting base 601, and the drive gear 603 is coaxially connected to the output shaft of the drive motor 602; a gear ring 503 is coaxially mounted on the outer surface of the rotating disk 500, and the gear ring 503 meshes with the drive gear 603. Therefore, the rotation of the rotating disk 500 can be indirectly controlled by the drive motor 602. The drive motor 602 is specifically a servo motor, and its function is to facilitate the control of the flipping of the square steel cage.

[0021] Furthermore, such as Figure 3 As shown, the operating port 501 is rectangular. The inner four walls of the operating port 501 are provided with hidden grooves 504. A rotating seat 505 is movably arranged inside the hidden grooves 504. A sliding shaft 506 is rotatably connected to the rotating seat 505. Through holes 507 are evenly provided on the rotating seat 505 along the radial direction of the rotating disk 500. The outer surface of the rotating disk 500 is threaded with positioning bolts 508 that are compatible with the through holes 507. When the positioning bolts 508 are connected inside the through holes 507, the position of the rotating seat 505 is fixed. The purpose of providing multiple through holes 507 is to facilitate the adjustment of the distance between the sliding shaft 506 and the center of the rotating disk 500 to accommodate steel cages of different specifications.

[0022] This embodiment also includes a cleaning frame 700, which is mounted on the base 200. The cleaning frame 700 has a rectangular structure, and steel wire roller brushes 701 are rotatably connected to all four sides of the interior of the cleaning frame 700. The axial direction of the steel wire roller brushes 701 is parallel to the corresponding sidewalls of the cleaning frame 700. Figure 6 As shown, both ends of the rotating shaft of the wire roller brush 701 are provided with bevel gears 702, and the bevel gears 702 at the ends of two adjacent wire roller brushes 701 mesh with each other; specifically, the wire roller brush 701 is composed of a rotating shaft and steel wires distributed on the outer surface of the rotating shaft, and bearings are also sleeved at both ends of the rotating shaft of the wire roller brush 701. The bearings are fixedly connected to the inner wall of the cleaning frame 700 through bearing seats 713; since the bevel gears 702 at the ends of two adjacent wire roller brushes 701 mesh with each other, as long as one wire roller brush 701 rotates, it can synchronously drive the other wire roller brushes 701 to rotate.

[0023] Furthermore, a cleaning chamber 703 is provided inside the side wall of the cleaning frame 700, and several spray pipes 704 are provided on the inner wall of the cleaning frame 700. The cleaning chamber 703 is connected to an external water source, and the spray pipes 704 are connected to the cleaning chamber 703. The ends of the spray pipes 704 are equipped with nozzles 705. Specifically, the number of spray pipes 704 corresponds one-to-one with the number of main reinforcing bars 101, and when the wire brush 701 contacts the reinforcing bar 102, the nozzles 705 at the ends of the spray pipes 704 are all aligned with the contact points between the corresponding main reinforcing bar 101 and the reinforcing bar 102. Figure 6 As shown; a cleaning motor 706 is also provided on the outside of the cleaning frame 700. The output shaft of the cleaning motor 706 is coaxially connected to one of the wire roller brushes 701. The cleaning motor 706 is used to drive several wire roller brushes 701 to rotate. A solenoid valve 707 is also provided on the spray pipe 704. A water inlet 712 is also provided on the outer surface of the cleaning frame 700. The water inlet 712 is connected to an external water source through a pipeline. The water source needs to be connected to the water inlet 712 through a booster pump. Its function is to increase the water pressure inside the cleaning chamber 703. When the solenoid valve 707 is opened, the water inside the cleaning chamber 703 can be sprayed out through the nozzle 705.

[0024] Furthermore, lifting blocks 708 are movably installed on both the left and right sides of the interior of the cleaning frame 700. The lifting blocks 708 are located between the gaps of two adjacent main reinforcing bars 101, and their bottom ends are arc-shaped. Conductive copper sheets 709 are also attached to the bottom surface of the lifting blocks 708. When the conductive copper sheet 709 contacts one reinforcing bar 102, the wire brush 701 contacts the other reinforcing bar 102. A power supply 800 is also provided on the base 200. Figure 9As shown, two conductive copper sheets 709 are connected to the positive and negative poles of the power supply 800 via wires. The cleaning motor 706 is located on the line connecting the negative pole of the power supply 800 to the conductive copper sheet 709. Several solenoid valves 707 are connected in parallel on the line connecting the positive pole of the power supply 800 to the conductive copper sheet 709. Therefore, when both conductive copper sheets 709 are in contact with the reinforcing rib 102, the circuit is connected, and the solenoid valves 707 and the cleaning motor 706 are energized, thereby precisely controlling the operation of the wire roller brush 701, which helps to save electricity and water resources.

[0025] In addition, the lifting block 708 is also provided with a mounting sleeve 710 on its exterior. The mounting sleeve 710 is fixedly installed on the inner wall of the cleaning frame 700. The mounting sleeve 710 is provided with a compression spring 711 inside. The two ends of the compression spring 711 abut against the inner wall of the mounting sleeve 710 and the lifting block 708, respectively. Both the lifting block 708 and the mounting sleeve 710 are made of insulating material. Figure 8 As shown, the lifting block 708 can move freely inside the mounting sleeve 710, and in its natural state, the compression spring 711 is in a compressed state, which makes the conductive copper sheet 709 in close contact with the reinforcing rib 102.

[0026] In summary, in practical use, when welding a square steel reinforcement cage, the cage is inserted into the two operating ports 501 from left to right. Figure 2 In the state shown, the three-axis positioning mechanism 201 and welding mechanism 300 are then activated to weld the contact points on the top surface of the rebar cage. After the contact points on the top surface of the rebar cage are welded, the rebar cage is rotated 90° by the drive mechanism 600 to weld the top surface of the rebar cage. This process is repeated until all four sides of the rebar cage are welded. Then, the rebar cage is pushed to the right a certain distance. When the rebar cage moves to the right, the two conductive copper sheets 709 will continuously contact the reinforcing rib 102. When the conductive copper sheet 709 contacts the reinforcing rib 102, the circuit is turned on and the wire brush 701 starts to work, thereby accurately removing the welding slag at the welding point.
