[0045] As a preferred embodiment, the locking piece 15 is an electromagnet. Specifically, the electromagnet is liftable through a pneumatic cylinder and is arranged on the base 1.

[0046] After the base travels to the position, the pneumatic cylinder is elongated to make the electromagnet adsorb to the flange plate, so that the base is locked on the flange plate.

[0047] The bolt dispenser 2 is arranged on the base 1. The bolt dispenser 2 is formed with a receiving groove. The receiving groove is used for receiving the shank of a plurality of bolts 7. The shank of the bolt 7 is movably provided with a porcelain ring 8. The porcelain ring 8 is arranged in the notch of the receiving groove.

[0048] One end of the receiving groove is elastically provided with a pushing piece. The pushing piece abuts against the porcelain ring 8. In the present embodiment, the width of the receiving groove is adapted to the outer diameter size of the shank of the bolt. The outer diameter size of the porcelain ring is adapted to the outer diameter size of the bolt cap. The inner diameter size of the porcelain ring is adapted to the outer diameter size of the shank.

[0049] The opposite sides of the porcelain ring are respectively placed on the outer walls of the opposite sides of the slot of the accommodating groove. The lower part of the pushing member is slidably arranged in the accommodating groove, and the upper part of the pushing member is pressed against the porcelain ring and the nail cap. The pushing member is connected to one end of the accommodating groove by a spring. The spring is a coil spring arranged along the length direction of the accommodating groove. The spring pushes the peg and the porcelain ring towards the other end of the accommodating groove through the pushing member.

[0050] As a preferred embodiment, flange plates 21 are respectively formed on the opposite sides of the nailer 2. The accommodating groove is formed on the flange plate 21.

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

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

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

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

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

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

[0057] As a preferred embodiment, the number of the first sliding table modules 31 is two. The two first sliding table modules 31 are respectively arranged on the opposite sides of the nailer 2.

[0058] The grabbing mechanism 4 is installed on the lower end of the third sliding table module 33. The grabbing mechanism 4 is used for grabbing the porcelain ring 8.

[0059] In the embodiment, referring to Figure 6 , the grabbing mechanism 4 includes a base 41, a supporting plate 42 and a driving member.

[0060] In the embodiment, the base 41 is installed on the lower end of the third sliding table module 33. The side part of the base 41 is provided with a sliding groove arranged along the horizontal direction.

[0061] The number of the supporting plates 42 is two. The two supporting plates 42 are respectively connected with sliding blocks. The sliding blocks are slidably arranged in the sliding groove.

[0063] In this embodiment, the driving member is a double-shaft air cylinder. The driving member is installed in the middle of the sliding groove. The two output shafts of the double-shaft air cylinder are respectively connected to a sliding block. By driving the two sliding blocks to move towards or away from each other through the double-shaft air cylinder, the two clamping plates clamp or release the porcelain ring.

[0064] When the double-shaft air cylinder contracts, the clamping plates clamp the porcelain ring (as shown in the state of Figure 5 ); then the double-shaft air cylinder elongates, at which time the clamping plates release the porcelain ring, but a limiting space is formed between the two clamping plates (as shown in the state of Figure 6 ), avoiding the porcelain ring from deviating. Finally, when the double-shaft air cylinder continues to elongate, the clamping plates are completely separated from the porcelain ring (as shown in the state of Figure 3 ).

[0067] The fourth sliding table module is a ball screw sliding table module. The fourth sliding table module and the third sliding table module are connected back to back.

[0068] The controller is signal connected to the motorized 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 application provides a construction method of a steel structure bolt welding equipment, comprising the following steps:

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

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

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

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

[0074] e. The controller uses the drive mechanism 3 to move the gripping mechanism 4 to the welding point of the stud 7.

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

[0076] g. The controller closes the locking element 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 equipment of the present invention is driven by electric rollers to move on the steel structure. Limiting members are provided on opposite sides of the steel structure to prevent the steel structure stud welding equipment from deviating along the length of the steel structure.

[0079] The steel structure stud welding equipment of the present invention is used for high-quality welding operations on large steel structural components such as steel beams. First, a servo motor on the base drives electric rollers, ensuring that the base can move precisely along a preset path. The servo motor not only provides the necessary driving force but also precisely controls the speed and position of the base. The electric rollers are driven by the servo motor, while the driven wheels are equipped with encoders to detect the actual travel distance of the base in real time. This design ensures that even if the electric rollers slip, the current position of the base can be accurately calculated, thus guaranteeing precise positioning during the welding process.

[0080] The drive mechanism consists of three-axis ball screw slide modules: X, Y, and Z. The X-axis represents the length of the steel structure's flange plate, the Y-axis represents the width of the flange plate, and the Z-axis represents the thickness of the flange plate. These modules are also driven by servo motors, enabling three-dimensional adjustment of the welding torch in space. Precise control in these three directions allows the welding torch to flexibly reach any position requiring welding, ensuring flexibility and accuracy during the welding process. The slide modules, with their high precision and low friction characteristics, ensure stable movement of the welding torch in space.

[0081] To ensure welding quality, the steel structure stud welding equipment of this invention is also equipped with a gripping mechanism. The ceramic ring can float up and down with the changes in the welding surface, always maintaining good contact with the welding surface. This protects the welding area from external contamination and ensures that spatter does not interfere with the welding process. In addition, the ceramic ring also helps maintain the shape of the weld pool, improving welding quality.

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

[0083] The electromagnet of the steel structure stud welding equipment is used to adsorb the base on the flange plate, and ensures stability during welding. The electromagnet generates a magnetic field when energized, and can firmly fix the base. The base does not directly contact the electromagnet during movement, avoiding the influence of friction on the movement of the base, and ensuring smooth welding operation.

[0084] The walking of the steel structure stud welding equipment adopts a servo motor to drive a walking electric roller, and the driven wheel is provided with an encoder for detection. The actual walking distance of the base is detected by the encoder, and the positioning of the base is not affected when the electric roller slips.

[0085] A three-axis sliding table module is arranged above the base and is driven by a servo motor.

[0086] The grabbing mechanism is used to ensure that the porcelain ring can be pressed on the steel beam.

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

[0088] The electromagnet is used to adsorb the base on the flange plate, ensuring the stability of the base during welding. The electromagnet does not contact the flange plate when the base moves.

[0089] The operation process of the steel structure stud welding equipment is as follows: the base is placed on the flange plate; the cylinder on the limiting part (the limiting part is installed on the base through the cylinder, and the cylinder is arranged in the width direction of the base) is operated, so that the limiting parts on both sides of the base abut against the side of the flange plate; the controller controls the electric roller to walk, and the base is opened to the welding starting position, and the zero point is confirmed; the distribution parameters (array mode) of the stud are inputted or the *.dwg file is imported on the control interface of the controller, and the system automatically identifies the stud welding coordinates; the stud and the porcelain ring are placed into the stud distributor; the controller starts the driving mechanism, the grabbing mechanism and the welding mechanism to automatically complete the material taking, positioning and welding of the stud and the porcelain ring; after welding a row, the electromagnet is released, the base automatically walks a certain distance, and the electromagnet is adsorbed on the flange plate again; during welding, the stud and the porcelain ring are supplemented manually, and the cable of the control system to the base is arranged.

[0090] The steel structure stud welding equipment realizes automatic stud welding, improves the working efficiency of stud welding, and effectively guarantees the welding quality of stud welding. The steel structure stud welding equipment replaces manual work, reduces the risk of manual operation, and reduces labor cost.

[0091] The above description is only the preferred embodiment of the present application and the explanation of the technical principles. It should be understood by those skilled in the art that the scope of the protection of the present application is not limited to the technical solutions formed by the specific combinations of the above technical features. It should also cover other technical solutions formed by the combinations of the above technical features or their equivalent features without departing from the concept of the present application. For example, the technical solutions formed by the mutual replacements of the above features and the technical features disclosed in the present application (but not limited to) with similar functions.
