[0002] Welding equipment is a device used to join two or more metal workpieces together by applying high temperature heat or pressure. Welding machines are widely used in industrial manufacturing, maintenance and metal processing.

[0003] The welding equipment mainly includes a welding table and a welding arm. The welding arm is placed on the side of the welding table. When welding is required, the welding arm controls the welding end of the welding arm head to move to the top of the welding table, and then performs welding operations on the workpiece to be welded on the welding table. In this structure, since the welding arm is located on the side of the welding table, the welding arm needs to reserve a certain length to compensate for the displacement of the welding arm in the horizontal direction, especially when the welding position is on the side of the welding table away from the welding arm, the welding arm needs to be longer. Therefore, the welding equipment of this structure needs to be equipped with a welding arm with a larger control stroke, which makes welding inconvenient and needs further improvement.

[0027] Combination Figures 1 to 3 The utility model robot welding equipment is further described.

[0028] A robot welding device is characterized by comprising a main beam 1, a mounting beam 3, a welding arm 7 and a welding workbench 2.

[0029] On the bottom surface of the main beam 1, there are a plurality of columns arranged and distributed along the length direction of the main beam 1. The main beam 1 is installed on the site through the plurality of columns, so that the main beam 1 is away from the ground. A control cabinet slide 4 that can slide along the length direction of the main beam 1 and a ladder 5 for operators to climb onto the main beam 1 are arranged on the main beam 1. The ladder 5 is located at one end of the main beam 1, and the upper side of the ladder 5 corresponds to the entrance of the control cabinet slide 4, so that the operator can enter the control cabinet slide 4 after climbing up the ladder 5. The installation beam 3 is perpendicular to the main beam 1 and fixed on the control cabinet slide 4, that is, the installation beam 3 is divided into two sections along the length direction, one section is a fixed section fixed in the control cabinet slide 4, and the other section extends to the main beam 1 and the installation section outside the control cabinet slide 4. The welding arm 7 is arranged on the installation section, and the welding workbench 2 is arranged on the side of the main beam 1 and is located below the welding arm 7.

[0030] The control cabinet slide 4 structure includes a slide plate 41, a top plate 42 and a sliding drive assembly.

[0031] The slide plate 41 is slidably fitted on the top surface of the main beam 1 through a guide rail assembly.

[0032] The sliding drive assembly is arranged between the slide plate 41 and the main beam 1, and drives the slide plate 41 to move along the length direction of the main beam 1. The specific structure of the sliding drive assembly includes a driving motor 431 and a driving rack 432, wherein the driving rack 432 is arranged on the top surface of the main beam 1 and extends along the length direction of the main beam 1; the driving motor 431 is arranged on the slide plate 41 in an inverted state, and a gear is arranged on the rotating shaft of the driving motor 431, and the gear is meshed with the driving rack 432. Therefore, after the driving motor 431 drives the gear to rotate, the slide plate 41 can move on the main beam 1 under the cooperation of the gear and the driving rack 432.

[0033] The top plate 42 is fixed on the top of the slide plate 41 by a plurality of brackets 421, so that the top plate 42 is separated from the slide plate 41, and an installation space 43 is formed between the top plate 42 and the slide plate 41 for the installation beam 3 to be inserted and fixed. The fixed section of the installation beam 3 is inserted into the installation space 43 and fastened to the slide plate 41 and the top plate 42 by bolts. The top surface of the top plate 42 is provided for the installation of a plurality of control cabinets 6, and a fence 422 is provided at the edge of the top plate 42 to protect the control cabinets 6 and the operator. An entrance corresponding to the upper end of the ladder 5 is reserved on the fence 422 for the operator to enter.

[0034] In the installation structure of the welding arm 7 on the installation section, the installation section has multiple installation positions for the welding arm 7, and the multiple installation positions are arranged along the length direction of the installation beam 3. This structure can be used for the installation of multiple welding arms 7, or the installation arms can be installed at different positions, so that the welding arm 7 corresponds to the welding workbench 2 up and down, thereby improving the convenience of welding.

[0035] The tail of the welding arm 7 has a mounting seat 71, and the side wall of the mounting seat 71 has a plurality of connecting ears 711, and bolts are matched in the connecting ears 711. The mounting position on the mounting section is located on the bottom surface of the mounting section and is composed of a plurality of threaded holes. Therefore, the mounting seat 71 can be fixed to the threaded holes of the corresponding mounting position through the connecting ears 711 and the corresponding bolts, and has the characteristic of convenient disassembly and assembly.

[0036] A secondary fastening assembly is also provided on the installation position, and the secondary fastening assembly includes a fastening frame 72 corresponding to each connecting ear 711, that is, the number of fastening frames 72 on each installation position is the same as the number of connecting ears 711 on each mounting seat 71, and they correspond one to one. The fastening frame 72 is an L-shaped structure, including a vertical fixing portion 721 fixed to the installation position by bolts and a horizontal fixing portion 722 located at the lower end of the vertical fixing portion 721 and extending to the bottom of the connecting ear 711. The horizontal fixing portion 722 is equipped with a fastening bolt 723, and the upper end of the fastening bolt is pressed against the connecting ear 711, thereby providing an upward pressure on the connecting ear 711, forming a secondary fastening structure, so that the welding arm 7 can be installed more stably on the installation position.

[0037] In the structure of the welding workbench 2, the specific number of the welding workbench 2 can be set according to actual needs. In this embodiment, there are two welding workbenches 2, and they are arranged along the length direction of the main beam 1. It should be noted that the sum of the lengths of the two welding workbenches 2 is less than the length of the main beam 1, so that the welding arm 7 can be moved to the top of each welding workbench 2 for welding operations. During the welding operation, the two welding workbenches 2 can be used interchangeably. When the first welding workbench 2 is in welding operation, the next workpiece to be welded can be loaded onto the second welding workbench 2 that is not in operation. After the welding work on the first welding workbench 2 is completed, the welding arm 7 can be directly moved to the top of the second welding workbench 2 to perform welding operations on the workpiece to be welded fixed thereon. At the same time, the workpiece on the first workbench can be unloaded and reloaded, which can significantly improve the convenience of welding.

[0038] Each welding workbench 2 comprises a rectangular table 21 and a base frame for mounting the table 21 and driving the table 21 to rotate. The table 21 is used to fix the welding tooling, and the welding work is used to fix the workpiece to be welded. The length direction of the table 21 is in the same direction as the extension direction of the main beam 1. The length direction of the rectangular table 21 is in the same direction as the extension direction of the main beam 1, which can facilitate the covering of the welding arm 7 moving along the length direction of the main beam 1 on the table 21, and facilitate the docking with the welding position.

[0039] The base frame includes a U-shaped frame 22, a turntable 23 arranged on both sides of the U-shaped frame 22, and a rotating motor driving the turntable 23 to rotate. The turntable 23 has a connecting block, and the two ends of the table 21 are fixed to the connecting blocks of the two turntables 23 by corresponding bolts. The rotating setting of the table 21 can rotate the position of the workpiece on the table 21 that needs to be welded, further facilitating the correspondence between the welding position and the welding end of the welding arm 7, so as to further improve the convenience of welding.
