Description

Technical Field

[0001] The utility model relates to the technical field of fan welding, in particular to an adjustable welding device for fan production. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is China's customary abbreviation for gas compression and gas delivery machinery. Commonly referred to fans include ventilators, blowers, and wind turbines.

[0003] However, when the existing welding device is in use, the molten iron filings splash easily and cause burns to the clothes or skin of the workers, which poses certain safety hazards.

[0004] In order to solve the above-mentioned defects, in the prior art, a Chinese patent with publication number CN220698678U discloses a welding device for fan production, including a processing table, a three-axis slide, and a welding machine. The three-axis slide is installed on the upper surface of the processing table, and the welding machine is installed on the three-axis slide. A mounting frame is provided under the processing table. The impeller is placed on the inner side of the clamping base and the impeller is fixed by tightening the clamping nut. The moving block can be driven to move by starting the two-way hydraulic rod, and the moving block can be used to drive the driving rod to drive, and then the driving rod drives the bearing platform to rise. The bearing platform can be used to lift the impeller to the top of the processing table, which is convenient for the welding machine to perform welding. At the same time, the moving block will drive the connecting rod to move when moving, so that the two protective plates can be closed, which can prevent sparks from flying during welding.

[0005] During use, the above-mentioned device utilizes a connecting rod to drive the protective plate to close, thereby preventing sparks from flying. However, in the above-mentioned device, the connecting rod only drives the protective plate to close. When the welded object is manually fixed, the flying sparks will fall onto the person's body, making it easy for the person to be injured. Therefore, in actual use, manual fixation of the welded object may cause personal injury. Utility Model Content
