The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0049] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0052] like Figures 1-7As shown, this utility model provides a welding device, including a fixed base 1, an adjusting base 2, a fixed electrode 3, a driving mechanism 4, and a movable electrode 5. The fixed base 1 is provided with an arc-shaped sliding track 11. The adjusting base 2 can slide along the sliding track 11 for orientation adjustment. The adjusting base 2 is provided with a wire inlet hole 21. The fixed electrode 3 is mounted on the adjusting base 2. The driving mechanism 4 is mounted on the adjusting base 2. The movable electrode 5 is mounted on the output end of the driving mechanism 4. A reinforcing bar passing through the wire inlet hole 21 is located between the fixed electrode 3 and the movable electrode 5. The driving mechanism 4 can drive the movable electrode 5 to move towards the fixed electrode 3.

[0053] In this invention, compared to a circular track, the fixed base 1 with an arc-shaped sliding track 11 occupies less space. On this basis, the adjusting base 2 supports the fixed electrode 3, the driving mechanism 4, and the movable electrode 5, and can drive the fixed electrode 3, the driving mechanism 4, and the movable electrode 5 to slide along the sliding track 11 for orientation adjustment, making the orientation adjustment of welding more flexible and convenient. It eliminates the need for the configuration of the driving mechanism 4 such as a robot, reduces processing costs, and can meet the welding needs of stirrups 100 of various sizes and shapes.

[0054] Specifically, the sliding track 11 includes two coaxially arranged arc-shaped rails, and the adjusting seat 2 can slide along the two arc-shaped rails. The two arc-shaped rails cooperate to prevent the adjusting seat 2 from translating when sliding, so that the adjusting seat 2 can deflect stably and reliably for orientation adjustment.

[0055] More specifically, the welding device also includes fasteners. The arc-shaped rail has an elongated hole 111, through which the fastener passes and is screwed to the adjusting seat 2. The fastener has a tightened state and a released state. When the fastener is in the tightened state, the fixing seat 1 is clamped between the adjusting seat 2 and the head of the fastener. When the fastener is in the released state, the adjusting seat 2 can slide along the arc-shaped rail. The above configuration allows the adjusting seat 2 to be reliably locked in the set position.

[0056] In this embodiment, both the fixed seat 1 and the adjusting seat 2 are plate-shaped structures, and the fasteners are bolts. At least one bolt is inserted in each elongated hole 111. In the tightened state, the head of the bolt abuts against the fixed seat 1 to lock the adjusting seat 2. In the released state, the distance between the adjusting seat 2 and the head of the fastener is greater than the thickness of the fixed seat 1, so that the adjusting seat 2 can slide in the elongated hole 111 through the fastener.

[0057] In other embodiments, the arc-shaped rail can also be a grooved rail. The adjusting seat 2 is provided with a slider, which is slidably disposed in the grooved rail. In this case, the fastener is a bolt or screw, which is screwed to the adjusting seat 2 and can abut against the fixed seat 1.

[0058] Specifically, the fixed base 1 is provided with a clearance hole 12, and the inlet hole 21 is connected to the clearance hole 12. The above arrangement allows the reinforcing bar to be fed in with the clearance hole 12 as a reference, and then extends into the space between the fixed electrode 3 and the movable electrode 5 through the inlet hole 21, which is more stable and reliable.

[0059] More specifically, the sliding track 11 is centered on the axis of the clearance hole 12. This arrangement ensures that when the adjusting seat 2 slides relative to the fixed seat 1, the inlet hole 21 is always reliably connected to the clearance hole 12.

[0060] In this embodiment, the inlet hole 21 is elongated, and its length direction is parallel to the moving direction of the driving mechanism 4 driving the movable electrode 5. This arrangement allows the inlet hole 21 to initially limit the movement of the reinforcing bar inserted therein.

[0061] Specifically, the drive mechanism 4 includes a driver 41 and an insulating plate 42. The driver 41 is mounted on the adjusting base 2, and the movable electrode 5 is connected to the output end of the driver 41 via the insulating plate 42. By setting the insulating plate 42, the fixed electrode 3 and the movable electrode 5 can perform welding operations safely and reliably.

[0062] More specifically, the drive mechanism 4 also includes a support frame 43, a guide post 44, and an electrode holder 45. The support frame 43 is mounted on the adjusting base 2, the driver 41 is mounted on the support frame 43, the guide post 44 is slidably disposed on the support frame 43, one end is connected to the output end of the driver 41, and the other end is connected to the insulating plate 42. The electrode holder 45 is mounted on the side of the insulating plate 42 opposite to the guide post 44, and the movable electrode 5 is mounted on the side of the electrode holder 45 opposite to the insulating plate 42. The support frame 43, guide post 44, and electrode holder 45 cooperate to enable the driver 41 to drive the movable electrode 5 more stably and reliably.

[0063] In this embodiment, the actuator 41 is a cylinder. In other embodiments, the actuator 41 can also be a linear drive device such as an electric cylinder.

[0064] Specifically, the electrode holder 45 is provided with a first flow channel 451 and a first inlet / outlet 452 and a second inlet / outlet 453 connected to the first flow channel 451. The movable electrode 5 is connected to the opening of the first flow channel 451. Since welding generates a large amount of heat, cooling is required. In the above configuration, the first inlet / outlet 452 and the second inlet / outlet 453 are respectively a water inlet and a water outlet. The water entering from the water inlet flows through the movable electrode 5 in the first flow channel 451 and then flows out from the water outlet, thus achieving water cooling of the movable electrode 5.

[0065] More specifically, a water inlet copper core 46 is provided in the first flow channel 451, a first sink is provided on the movable electrode 5, a first threaded hole 454 is provided at the bottom of the first flow channel 451, and a first inlet / outlet 452 is connected to the first flow channel 451 through the first threaded hole 454. One end of the water inlet copper core 46 is screwed into the first threaded hole 454 and connected to the first inlet / outlet 452, and the other end extends into the first sink, so that cooling water can extend into the movable electrode 5 for cooling.

[0066] In this embodiment, the drive mechanism 4 further includes a guide rod 47, a copper limiting sleeve 48, and a fastening member 49. One end of the guide post 44 is provided with a first connecting block. The insulating plate 42 is a plate made of insulating material and is laid and installed on the first connecting block. The guide rod 47 passes through the sliding groove of the support frame 43 and is provided with a second connecting block at one end. The second connecting block is connected to the first connecting block by bolts, thereby interfering with the rotation of the guide post 44. A copper limiting sleeve 48 is provided on each side of the guide rod 47. Each copper limiting sleeve 48 is equipped with a fastening member 49. The fastening member 49 is a bolt and is screwed to the support frame 43. One end of the fastening member 49 extends into the sliding groove and is connected to the copper limiting sleeve 48. By limiting the two copper limiting sleeves 48, the guide rod 47 can be stably translated and extended.

[0067] In other embodiments, a guide groove can be provided on the guide post 44, extending along the axial direction of the guide post 44, and a steel key can be installed on the support frame 43, extending into the guide groove, thereby interfering with the rotation of the guide post 44.

[0068] Specifically, the welding device also includes a transformer 6, whose two output electrodes are a first output electrode 61 and a second output electrode 62. The first output electrode 61 is electrically connected to the fixed electrode 3, and the second output electrode 62 is electrically connected to the movable electrode 5. This arrangement ensures that the fixed electrode 3 and the movable electrode 5 can be reliably connected to the power supply.

[0069] More specifically, the first output electrode 61 is electrically connected to the fixed electrode 3 via the adjusting seat 2. This arrangement makes the electrical connection between the first output electrode 61 and the fixed electrode 3 simpler and more reliable.

[0070] In this embodiment, the adjusting seat 2 is an aluminum plate. Aluminum plates have good electrical conductivity and play a conductive role in welding. The first output electrode 61 is connected to the aluminum plate via a side-connecting copper seat 63. The fixed electrode 3 is connected to the aluminum plate via a brass base 64. The second output electrode 62 is connected to the electrode seat 45 via a flexible wire 65, and then electrically connected to the movable electrode 5. When the fixed electrode 3 and the movable electrode 5 clamp the longitudinal rib 200 and the stirrup 100, a closed circuit is formed, allowing welding to proceed. During the welding process, the aluminum plate also generates heat. The aluminum plate should have advantages such as high strength, corrosion resistance, light weight, and good electrical conductivity. Therefore, this embodiment uses 7075 alloy aluminum, but is not limited to 7075 alloy aluminum.

[0071] Specifically, the brass base 64 is provided with a second flow groove and a third and a fourth inlet / outlet connected to the second flow groove. The fixed electrode 3 is connected to the opening of the second flow groove. Due to the large amount of heat generated during welding, cooling is required. The third and the fourth inlet / outlet are water inlets and outlets, respectively. Water entering from the inlet flows through the fixed electrode 3 in the second flow groove and then flows out from the outlet, thus achieving water cooling of the fixed electrode 3. A water inlet copper core 46 can also be provided in the second flow groove. A second sink is provided on the fixed electrode 3. A second threaded hole is provided at the bottom of the second flow groove. One end of the water inlet copper core 46 is screwed into the second threaded hole and connected to the third inlet / outlet, while the other end extends into the first sink, so that cooling water can extend into the interior of the fixed electrode 3 for cooling.

[0072] More specifically, a small, flexible, and lightweight transformer 6 is selected. The transformer 6 has threaded holes on its side so that it can be installed on an aluminum plate. Furthermore, a flow channel is provided on the transformer 6 to connect the first output electrode 61 and the second output electrode 62. The flow channel is connected to the outside through the fifth inlet and outlet and the sixth inlet and outlet. When heat is generated during welding, the transformer 6 can be cooled by water cooling.

[0073] The welding device of this utility model is used to weld circular stirrup beams and columns. In addition, it can also weld longitudinal bars 200 and stirrups 100 of other shapes together, such as rectangular, circular and various shapes of stirrups 100.

[0074] This utility model also provides a welding method using the above-mentioned welding apparatus, comprising:

[0075] Step 1: Adjust the position of the adjusting seat 2 by sliding it along the sliding track 11 so that the line connecting the fixed electrode 3 and the movable electrode 5 is perpendicular to the tangent of the stirrup 100 at the point to be welded.

[0076] Step 2: Place the stirrup 100 to be welded between the fixed electrode 3 and the movable electrode 5;

[0077] Step 3: Insert the longitudinal rib 200 through the inlet hole 21 between the fixed electrode 3 and the movable electrode 5, so that the longitudinal rib 200 is located on the side of the stirrup 100 to be welded away from the fixed electrode 3.

[0078] Step 4: Drive mechanism 4 drives movable electrode 5 to move toward fixed electrode 3, so that the weldable parts of longitudinal rib 200 and stirrup 100 are sandwiched between fixed electrode 3 and movable electrode 5.

[0079] Step 5: Apply electricity to the fixed electrode 3 and the movable electrode 5 to weld the joints to be welded on the longitudinal rib 200 and the stirrup 100.

[0080] In the welding method of this utility model, compared with a circular track, the fixed seat 1 with an arc-shaped sliding track 11 occupies less space. On this basis, the adjusting seat 2 supports the fixed electrode 3, the driving mechanism 4 and the movable electrode 5, and can drive the fixed electrode 3, the driving mechanism 4 and the movable electrode 5 to slide along the sliding track 11 for orientation adjustment, making the orientation adjustment of welding more flexible and convenient. It eliminates the need for the configuration of the driving mechanism 4 such as the robot, reduces the processing cost, and can meet the welding needs of stirrups 100 of various sizes and shapes.

[0081] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
