Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
the magnet fixing and pulling-out device suitable for the welding tractor comprises a magnet 10, a fixing holder 20, a first connecting rod 30, a second connecting rod 40 and a supporting seat 50, wherein the first connecting rod 30 is hinged with the fixing holder 20; the magnet 10 is adsorbed and fixed below the fixed retainer 20, the fixed retainer 20 is detachably connected with the welding trolley 1, and the fixed retainer 20 can rotate around a shaft; the second connecting rod 40 is provided with a bent portion 41, the bent portion 41 is hinged with the supporting seat 50, and the supporting seat 50 is detachably fixed on the welding carriage 1 through threaded connection. Like this all fix fixed holder 20 and supporting seat 50 on welding carriage 1, magnet 10 adsorbs on work piece 2, rotating bending portion 41, second connecting rod 40 is so that use supporting seat 50 to rotate as the fulcrum and drive first connecting rod 30 upward movement, make first connecting rod 30 drive fixed holder 20 and do pivoting motion, utilize the light certain contained angle that produces between messenger magnet 10 and the work piece 2 of the lever principle of second connecting rod 40, thereby the effectual adsorption affinity that has reduced magnet 10, make magnet 10 very easily pull out from work piece 2 and take off. When the magnet 10 is adsorbed on the workpiece 2, the gravity center of the welding trolley 1 is lowered, when the welding trolley 1 moves, the transverse adsorption force between the magnet 10 and the workpiece 2 needs to be overcome, and the magnet 10 can slide on the workpiece 2, so that the phenomenon that the welding trolley 1 is easy to swing is relieved, the motion stability is improved, the welding quality is improved, and the application range is wide.
