The welding of GIS needs to be carried out strictly in accordance with relevant standards and specifications, including the selection of welding materials, the use of welding equipment, and the control of welding parameters. Specifically, the following measures can be taken: according to the material and usage environment of GIS, ensure that the welding equipment meets relevant safety requirements, and carry out necessary maintenance and repair. Strictly control welding parameters such as current, voltage, welding speed, and welding temperature to ensure the quality and stability of the weld.

[0003] Chinese Patent No. CN202220401450.1 discloses a 3D laser robot welding workstation for stainless steel GIS, which uses an articulated robot to perform welding on GIS, realizing the automated welding of GIS.

[0004] Regarding the above technical solution, the inventor believes that although the articulated robot has a high degree of flexibility, its cost is high and it is not easy to maintain, and it is prone to jitter during movement, and the welding accuracy needs to be improved. Summary of the Utility Model

[0005] In order to ensure automation of welding while improving welding accuracy and usage stability, this application provides a three-dimensional five-axis welding equipment.

[0006] A three-dimensional five-axis welding equipment provided by this application adopts the following technical solution:

First, the three-dimensional five-axis module drives the contour sensor to move in the X, Y, and Z directions. The contour sensor pre-scans the cabinet to obtain a three-dimensional contour model of the cabinet, and transmits the data of the three-dimensional contour model to the central control system. The central control system generates the weld path of the cabinet and converts the weld path into a control instruction, and finally sends a control instruction to the three-dimensional five-axis module to control the movement route of the three-dimensional five-axis module. The three-dimensional five-axis module drives the laser welding head to weld the cabinet, thereby realizing the precision welding of the gas-insulated switchgear. In this application, the three-dimensional five-axis module is used to drive the laser welding head to move.

First round holes are correspondingly arranged on both the adjustment plate and the fixing plate. A second round hole is provided on the fixing plate, and an arc-shaped adjustment hole corresponding to the second round hole is provided on the adjustment plate. The center of the arc-shaped adjustment hole on the adjustment plate coincides with the center of the first round hole.

[0012] By adopting the above technical solution, inserting bolts into the first round hole and the second round hole and screwing on nuts can fix the adjustment plate and the fixing plate. Through the setting of the arc-shaped adjustment hole, it is convenient for the adjustment plate to rotate around the center of the arc-shaped adjustment hole, so as to achieve the purpose of adjusting the pitch angle of the contour sensor.

[0014] By adopting the above technical solution, during welding and processing, the cabinet is clamped and fixed, reducing the possibility of the cabinet shifting on the processing table and ensuring welding precision and welding efficiency.

[0015] Optionally, the tooling mechanism includes a first positioning plate and a second positioning plate which are respectively abutted against two adjacent sides of the cabinet body. The first positioning plate and the second positioning plate are respectively fixed on the processing table. The tooling mechanism further includes a first clamping plate and a second clamping plate. The first clamping plate is arranged opposite to the first positioning plate, and the second clamping plate is arranged opposite to the second positioning plate. The processing table is provided with a first driving member for driving the first clamping plate to move towards the first positioning plate and a second driving member for driving the second clamping plate to move towards the second positioning plate.

[0016] By adopting the above technical solution, the four bottom side edges of the cabinet body are clamped and positioned by the first positioning plate, the second positioning plate, the first clamping plate and the second clamping plate, so as to avoid the possibility of the cabinet body shifting in the horizontal direction during welding processing.

[0017] Optionally, mounting bases are arranged at the bottoms of the first positioning plate, the second positioning plate, the first driving member and the second driving member. A plurality of positioning holes are evenly distributed on the processing table, and the mounting bases are connected with the positioning holes through fasteners.

[0018] By adopting the above technical solution, the installation positions of the first positioning plate, the second positioning plate, the first driving member and the second driving member can be adjusted according to different cabinet body specifications, so as to ensure the applicability of the tooling mechanism.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. Through the settings of the three-dimensional five-axis module, the three-dimensional five-axis module, the profile sensor and the central control system, the cabinet body to be welded and processed is placed on the processing table. First, the three-dimensional five-axis module drives the profile sensor to move in the X, Y, and Z directions. The profile sensor pre-scans the cabinet body to obtain a three-dimensional contour model of the cabinet body, and transmits the data of the three-dimensional contour model to the central control system. The central control system generates a weld path of the cabinet body and converts the weld path into a control instruction, and finally sends a control instruction to the three-dimensional five-axis module to control the movement route of the three-dimensional five-axis module. The three-dimensional five-axis module drives the laser welding head to weld the cabinet body, thereby realizing precise welding of the gas-insulated switchgear. In the present application, the three-dimensional five-axis module is used to drive the laser welding head to move.
