Description

Technical Field

[0001] The utility model relates to the technical field of welding parts of lawn mowers and sweeping robots, and in particular to a welding tool. Background Art

[0002] The main feature of the sweeping robot is that it is very convenient, reducing the time of manual sweeping and being more efficient. When cleaning, you only need to start the sweeping robot with one button to free your hands to do other things, which is more worry-free and labor-saving.

[0003] A lawn mower is also called a weed cutter, lawn mower, lawn trimmer, etc. A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. It consists of a cutter disc, an engine, running wheels, a walking mechanism, a blade, an armrest, and a control part.

[0004] Sweeping robots and lawn mowers are both cleaning tools. During production, their metal impellers and other components need to be welded using welding tooling.

[0005] For example, a high-frequency welding machine for welding impellers of sweeping robots, with application number CN202320838378.3 and publication date 20230801, includes a machine base and a high-frequency generator arranged on one side of the machine base; a turntable and a drive device for driving the turntable to rotate are provided on the machine base, at least two corresponding blade jigs are provided on the turntable, and each blade jig is also provided with at least two slots for inserting blades; a welding station and a loading station are provided around the turntable; a hose jig for installing a hose and a first cylinder for driving the hose jig up and down are provided at the welding station; the hose jig can be pressed together with the blade jig after being driven, and the blade and hose can be welded together by a high-frequency generator after being pressed together. The utility model rotates the blade jig with different hardness to the welding station by driving the turntable, and uses the cylinder to drive the hose jig to press together with the blade jig before high-frequency welding is performed, thereby enabling blades of different hardness to be welded to the hose.

[0006] The welding fixtures for components such as the impellers of sweeping robots and lawn mowers are mostly made of metal and cannot be adjusted, making it impossible to fix components of different diameters. Therefore, it is urgent to design a welding fixture to solve the above problem. Utility Model Content
