Although the welding head can be used to weld steel structure workpieces, it lacks a limiting function for the workpieces, so that the workpieces are prone to shift during the processing process, which in turn affects the welding quality of the welding equipment and reduces the practicality of the device.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A welding device for steel structure processing with a limiting function, including a protective working chamber. A through cavity is provided on one side of the protective working chamber, and the through cavity penetrates through the left and right sides of the protective working chamber. A welding robot assembly is arranged inside the protective working chamber. A driving frame component is arranged on one side of the welding robot assembly, and a welding head is arranged on one side of the driving frame component. A transparent protective plate is arranged on one side of the protective working chamber, and the transparent protective plate is a protective plate made of a transparent material.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The utility model discloses a welding device for steel structure processing with a limiting function. When an operator needs to weld two steel plates, the two groups of steel plates can be placed on the top surface of the workbench plate. At the same time, the positions of the two groups of steel plates are respectively placed below the two groups of positioning pressing blocks. After the side walls of the two groups of steel plates that need to be welded are butted against each other, the working modes of the two groups of hydraulic cylinders are started at the same time. The hydraulic cylinders extend and drive the positioning pressing blocks to extend. The positioning pressing blocks move downward in the direction close to the steel plates until the bottoms of the positioning pressing blocks are pressed down to the tops of the steel plates. Then, the two groups of positioning pressing blocks perform the limiting and stabilizing work on the two groups of steel plates, and the working modes of the two groups of hydraulic cylinders are closed. The operator starts the working mode of the welding robot assembly. The driving frame component and the driving component cooperate to drive the welding head to move in the direction specified by the operator. Then, the cooperation between the driving frame component and the driving component will drive the welding head to move to the connection position between the two plates, and the welding head performs welding work on this position until the work is completed. When the work is completed, the two groups of hydraulic cylinders contract at the same time. The hydraulic cylinders drive the positioning pressing blocks to move upward until the positioning pressing blocks are completely away from the steel plates, and the working mode of the hydraulic cylinders is closed, waiting for the operator to unload the workpiece later. This setting can complete the limiting and fixing work of the steel structure workpiece through the cooperation of the two groups of positioning components, prevent the workpiece from shifting during the welding process, and affect the working quality of the device. Moreover, the positioning components are simple and quick to operate, improving the practicability of the equipment.

[0016] 2. Since light will also cause certain harm to people's eyes when the welding robot assembly is in use, and laser radiation will also pose a health hazard to the operators, the welding work of the welding robot assembly is carried out inside the protective working chamber. When the device is working, the operator can stand in front of the transparent protective plate to observe the welding work inside the protective working chamber. The user can observe the welding work of the welding robot assembly through the transparent protective plate, and the transparent protective plate plays a role in protecting the eyes of the staff. When the welding work is completed and the working mode of the welding robot assembly is closed, when the workpiece needs to be taken out, the operator can move to the side access opening of the protective working chamber. At this time, the operator starts the first motor, and the first motor drives the first lead screw to rotate forward. The first lead screw drives the moving block to move horizontally forward along the limiting groove. The moving block drives the workbench plate and the welded workpiece to move in the direction close to the operator until the workbench plate drives the workpiece to move to the position closest to the operator. At this time, it is convenient for the operator to take down the workpiece processed on the top surface of the workbench plate. Then, the first motor drives the first lead screw to rotate reversely. The first lead screw drives the moving block to move horizontally backward along the limiting groove, and the workbench plate contracts towards the bottom support seat until the workbench plate returns to its original position. During the horizontal movement of the workbench plate, the limiting plate slides along the corresponding limiting cavity, which is beneficial to improving the stability of the movement of the workbench plate. This setting is convenient for the operator to unload the welded steel structure workpiece, is simple to operate, and improves the practicability of the device. Description of the Drawings

[0031] In summary: The present utility model discloses a welding device for steel structure processing with a limiting function. The welding robot assembly 3 is a conventional device well-known to those skilled in the art and purchased on the market. The model of the welding robot assembly 3 of this device adopts the welding device of SZGH-HZ2000-B-6. In this application, we only use it and do not improve its structure and function. Its setting method, installation method, and electrical connection method can be debugged and operated by those skilled in the art as long as they follow the requirements of its user manual, and will not be elaborated here. When an operator needs to weld two steel plates, the two groups of steel plates can be placed on the top surface of the workbench plate 42, and at the same time, the positions of the two groups of steel plates are respectively placed below the two groups of positioning blocks 24. After the side walls of the two groups of steel plates that need to be welded are butted against each other, the working modes of the two groups of hydraulic cylinders 23 are simultaneously started. The hydraulic cylinders 23 extend and drive the positioning blocks 24 to extend. The positioning blocks 24 move downward in the direction close to the steel plates until the bottoms of the positioning blocks 24 are pressed down to the tops of the steel plates. Then, the two groups of positioning blocks 24 perform the limiting and stabilizing work on the two groups of steel plates, and the working modes of the two groups of hydraulic cylinders 23 are closed. The operator starts the working mode of the welding robot assembly 3. The driving frame component 31 and the driving component cooperate to drive the welding head 32 to move in the direction specified by the operator. Then, the cooperation between the driving frame component 31 and the driving component will drive the welding head 32 to move to the connection position between the two plates, and the welding head 32 welds this position until the work is completed. When the work is completed, the two groups of hydraulic cylinders 23 contract simultaneously. The hydraulic cylinders 23 drive the positioning blocks 24 to move upward until the positioning blocks 24 are completely away from the steel plates, and the working mode of the hydraulic cylinders 23 is closed, waiting for the operator to unload the workpiece later. This setting can complete the limiting and fixing work of the steel structure workpiece through the cooperation of the two groups of positioning components 2, prevent the workpiece from shifting during the welding process, and affect the working quality of the device. Moreover, the positioning component 2 is simple and fast to operate, improving the practicability of the equipment;

[0032] Since the light will also cause certain harm to people's eyes when the welding robot component 3 is in use, and the laser radiation will also pose a health hazard to the operators, the welding operation of the welding robot component 3 is carried out inside the protective working chamber 1. When the device is working, the operator can stand in front of the transparent protective plate 11 to observe the welding operation inside the protective working chamber 1. The user can observe the welding operation of the welding robot component 3 through the transparent protective plate 11, and the transparent protective plate 11 plays a role in protecting the eyes of the staff. When the welding operation is completed and the working mode of the welding robot component 3 is turned off, and the workpiece needs to be taken out, the operator can move to a position and stand at the side opening of the protective working chamber 1. At this time, the operator turns on the first motor 47, and the first motor 47 drives the first lead screw 48 to rotate forward. The first lead screw 48 will drive the moving block 46 to move horizontally forward along the limiting groove 44. The moving block 46 drives the workbench plate 42 and the welded workpiece to move in the direction close to the operator until the workbench plate 42 drives the workpiece to move to the position closest to the operator. At this time, it is convenient for the operator to take off the workpiece processed on the top surface of the workbench plate 42. Then the first motor 47 drives the first lead screw 48 to rotate reversely, and the first lead screw 48 drives the moving block 46 to move horizontally backward along the limiting groove 44, and the workbench plate 42 contracts towards the bottom support seat 41 until the workbench plate 42 returns to its original position. During the horizontal movement of the workbench plate 42, the limiting plate 45 slides along the corresponding limiting cavity 43, which is beneficial to improving the stability of the movement of the workbench plate 42. This setting is convenient for the operator to cut the welded steel structure workpiece, with simple operation and improved practicality of the device.
