[0039] In this embodiment, the steel structure stud welding device of the present invention is used to weld studs to a steel structure, wherein the steel structure is an I-shaped steel beam, and the studs are welded to the outer side of the flange plate of the I-shaped steel beam.

[0040] The base 1 is in the shape of an elongated strip. The base has a front end and a rear end. The front-to-back direction of the base is based on the traveling direction of the base, wherein the front end of the base is the front of the base in the traveling direction, and the rear end of the base is the rear of the base in the traveling direction.

[0041] The front and rear ends of the base 1 are respectively provided with a motorized roller 11 and a driven wheel 12.

[0043] In this embodiment, the two opposite sides of the front and rear ends of the base are respectively provided with limit members through brackets. The limit members are rollers. The wheel surface of the rollers abuts against the side of the flange plate, so that the base moves along the length direction of the flange plate to avoid deviation.

[0044] A locking member 15 for locking the steel structure 6 is liftably mounted on the base 1 .

[0045] As a preferred embodiment, the locking member 15 is an electromagnet. Specifically, the electromagnet is installed on the base 1 in a movably movable manner via a cylinder.

[0046] After the base moves into position, the cylinder extends to allow the electromagnet to be attracted to the flange plate, thereby locking the base on the flange plate.

[0047] The nail distributor 2 is mounted on the base 1. The nail distributor 2 is formed with a receiving groove. The receiving groove is used to receive the nail rods of a plurality of bolts 7. The nail rods of the bolts 7 are movably penetrated with a ceramic ring 8. The ceramic ring 8 is placed on the notch of the receiving groove.

[0048] A push piece is elastically mounted at one end of the receiving groove. The push piece presses against the ceramic ring 8. In this embodiment, the width of the receiving groove is adapted to the outer diameter of the nail rod of the stud. The outer diameter of the ceramic ring is adapted to the outer diameter of the nail cap of the stud. The inner diameter of the ceramic ring is adapted to the outer diameter of the nail rod.

[0049] The opposite sides of the ceramic ring are respectively placed on the opposite outer walls of the notch of the receiving groove. The lower part of the push-pull member is slidably arranged in the receiving groove, and the upper part of the push-pull member presses against the ceramic ring and the nail cap. The push-pull member is connected to one end of the receiving groove through a spring. The spring is a coil spring, and the coil spring is arranged along the length direction of the receiving groove. The spring pushes the bolt and the ceramic ring to the other end of the receiving groove through the push-pull member.

[0050] As a preferred embodiment, flange plates 21 are formed on opposite sides of the nail distributor 2. The receiving grooves are formed on the flange plates 21.

[0051] In this embodiment, the nail distributor 2 is arranged along the length direction of the base 1 .

[0052] The driving mechanism 3 includes a first slide module 31 , a second slide module 32 and a third slide module 33 .

[0053] In this embodiment, the first slide module 31 , the second slide module 32 and the third slide module 33 are ball screw slide modules respectively.

[0054] Specifically, the first slide module 31 is installed on the base 1. The first slide module 31 is arranged along the length direction of the base 1.

[0055] The second slide module 32 is installed on the slide of the first slide module 31. The second slide module 32 is arranged along the width direction of the base 1.

[0056] The slide of the third slide module 33 is installed on the slide of the second slide module 32. The third slide module 33 is arranged along the vertical direction.

[0058] The grabbing mechanism 4 is installed at the lower end of the third slide module 33. The grabbing mechanism 4 is used to grab the ceramic ring 8.

[0059] In this embodiment, see Figure 6 As shown, the grabbing mechanism 4 includes: a base 41, a support plate 42, and a driving member.

[0060] In this embodiment, the base 41 is installed at the lower end of the third slide module 33. The side of the base 41 is provided with a slide groove arranged in the horizontal direction.

[0061] There are two supporting plates 42. The two supporting plates 42 are respectively connected with sliders. The sliders are slidably arranged in the slide grooves. The bottom wall of the supporting plate 42 is connected with a clamping plate 43 through an ear plate. A clamping space for clamping the ceramic ring 8 is formed between the two clamping plates 43.

[0062] The driving member is connected between the sliders on the two support plates 42. The driving member signal is connected to the controller.

[0063] In this embodiment, the driving member is a double-axis cylinder. The driving member is installed in the middle of the slideway. The two output shafts of the double-axis cylinder are respectively connected to a slider. The two sliders are driven by the double-axis cylinder to move toward or away from each other, so that the two clamps clamp the ceramic ring or release the ceramic ring.

[0064] When the double-axis cylinder contracts, the clamping plate holds the ceramic ring (such as Figure 5 Afterwards, the double-axis cylinder extends, and the clamping plate releases the ceramic ring, but a limited space is formed between the two clamping plates (such as Figure 6 Finally, when the double-axis cylinder continues to extend, the clamping plate and the ceramic ring are completely separated (as shown in the figure). Figure 3 status shown).

[0065] The welding mechanism 5 is movably mounted on the third slide module 33. The welding mechanism 5 is located above the grabbing mechanism 4.

[0066] Specifically, in this embodiment, the welding mechanism 5 is escalably mounted on the third slide module 33 via the fourth slide module 51. The fourth slide module 51 is arranged in the same direction as the third slide module 33. The fourth slide module 51 is signal-connected to the controller.

[0067] The fourth slide module is a ball screw slide module, and the fourth slide module is connected back to back with the third slide module.

[0068] The controller signal is connected to the electric roller 11 , the encoder 13 , the locking member 15 , the driving mechanism 3 , the grabbing mechanism 4 and the welding mechanism 5 .

[0069] The present invention provides a construction method of a steel structure stud welding device, comprising the following steps:

[0070] a. The controller starts the electric roller 11 and based on the signal collected by the encoder 13, the base 1 moves to the construction position along the length direction of the steel structure 6.

[0071] b. The controller activates the locking member 15 to lock the steel structure 6.

[0072] c. The controller starts the driving mechanism 3 , and the first slide module 31 , the second slide module 32 and the third slide module 33 cooperate to move the grabbing mechanism 4 to the bolt 7 in the nail distributor 2 .

[0073] d. The controller starts the grabbing mechanism 4 to grab the ceramic ring 8 on the stud 7.

[0074] e. The controller drives the mechanism 3 to move the grabbing mechanism 4 to the welding point of the bolt 7.

[0075] f. The controller starts the welding mechanism 5 and welds the bolt 7 to the steel structure 6.

[0076] g. The controller closes the locking piece 15 to release the steel structure 6.

[0077] h. Repeat steps a to g until all studs 7 are welded.

[0078] The steel structure stud welding device of the present invention is driven by an electric roller to move on the steel structure. The limiters are arranged on opposite sides of the steel structure so that the steel structure stud welding device of the present invention will not deviate when moving along the length direction of the steel structure.

[0079] The steel structure stud welding equipment of the present invention is used to perform high-quality welding operations on large steel structures such as steel beams. First, the servo motor on the base drives the electric roller to ensure that the base can move accurately on the preset path. The servo motor not only provides the necessary driving force, but also accurately controls the speed and position of the base. The electric roller is driven by the servo motor, and the driven wheel is equipped with an encoder for real-time detection of the actual travel distance of the base. This design ensures that even if the electric roller slips, the current position of the base can be accurately calculated, thereby ensuring precise positioning during the welding process.

[0080] The drive mechanism is composed of three-axis ball screw slide modules of X, Y, and Z. The X direction is the length direction of the flange plate of the steel structure, the Y direction is the width direction of the flange plate, and the Z direction is the thickness direction of the flange plate. These modules are also driven by servo motors, which can realize the three-dimensional adjustment of the welding gun in space. Through the precise control of these three directions, the welding gun can flexibly reach any position where welding is required, ensuring flexibility and accuracy during the welding process. The slide module, with its high precision and low friction characteristics, can ensure the stable movement of the welding gun in space.

[0081] In order to ensure the welding quality, the steel structure stud welding equipment of the present invention is also equipped with a grabbing mechanism. The ceramic ring can float up and down with the changes of the welding surface, and always maintain good contact with the welding surface, which can not only protect the welding area from external contamination, but also ensure that the spatter during welding will not interfere with the welding process. In addition, the ceramic ring can also help maintain the shape of the welding pool and improve the welding quality.

[0082] The welding mechanism of the steel structure stud welding equipment of the present invention can automatically complete the arc drawing preparation before welding and the downward pressing action during welding, ensuring the stability of the arc during welding and the appropriate contact pressure between the welding gun and the welding surface, thereby improving the welding efficiency and quality.

[0083] The electromagnet of the steel structure stud welding device of the present invention is used to adsorb the base on the flange plate to ensure stability during the welding process. The electromagnet generates a magnetic field when energized, which can firmly fix the base. At the same time, the base does not directly contact the electromagnet during the movement, avoiding the influence of friction on the movement of the base, and ensuring the smooth progress of the welding operation.

[0084] The steel structure stud welding equipment of the present invention uses a servo motor to drive the electric roller for walking, and the driven wheel belt is equipped with an encoder for detection. The actual walking distance of the base is detected by the encoder, and when the electric roller slips, it does not affect the positioning of the base.

[0085] The base is equipped with an X, Y, and Z three-axis slide module, which is driven by a servo motor.

[0086] The gripping mechanism is used to ensure that the ceramic ring can be pressed tightly onto the steel beam.

[0087] The welding mechanism is used to realize a series of welding actions such as arc drawing and pressing down.

[0088] The base is adsorbed on the flange plate by an electromagnet to ensure the stability of the base during welding. When the base moves, the electromagnet does not contact the flange plate.

[0089] The operation process of the steel structure stud welding equipment of the present invention is as follows: place the base on the flange plate; operate the cylinder on the limit piece (the limit piece is installed on the base through the cylinder, and the cylinder is arranged along the width direction of the base) to make the limit pieces on both sides of the base abut against the side of the flange plate; the controller controls the electric roller to move, opens the base to the welding starting position, and confirms the zero point; manually inputs the distribution parameters of the stud (array mode) in the control interface of the controller or imports the *.dwg file, and the system automatically identifies the stud welding coordinates; manually puts the studs and ceramic rings into the stud dispenser; the controller starts the driving mechanism, the grasping mechanism and the welding mechanism to automatically complete the material collection, positioning and welding of the studs and ceramic rings; after a row of welding is completed, the electromagnet is released, the base automatically moves a certain distance, and the electromagnet absorbs the flange plate again; during the welding process, the studs and ceramic rings are manually replenished, and the cables from the control system to the base are sorted.

[0090] The steel structure stud welding equipment of the present invention realizes automated stud welding and improves the working efficiency of stud welding. The steel structure stud welding equipment of the present invention adopts mechanized operation and effectively ensures the welding quality of stud welding. The steel structure stud welding equipment of the present invention replaces manual labor, reduces the risk of manual labor, and reduces labor costs.

[0091] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
