Burr removing device at pipe fitting welding portion

Abstract

The invention discloses a burr removing device at a pipe fitting welding portion, and aims at solving the problem that existing sand paper easily scratches hands and the resource is wasted at the sametime. The burr removing device comprises a first rotation plate, a second rotation plate, a third rotation plate, a fourth rotation plate, grooves, sleeves, fixed rings, a first connecting block, anda second connecting block, the first rotation plate, the second rotation plate, the third rotation plate and the fourth rotation plate are hinged to rotation shafts, polishing layers are welded to the insides of the grooves, a screw is in threaded connection with the portion between the sleeves, baffles are welded to the outer ends of the screw, force application rods are in threaded connection with the inside of the fixed rings, grasping rods are welded to the upper ends of the force application rods, and a spiral spring is welded between the first connecting block and the second connectingblock. Through cooperation of the polishing layers, the pipe fitting welding portion is conveniently polished in a dislocation mode, through the force application rods, more labor is saved, and the burr removing device is convenient to operate and worthy of application and popularization.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a device for trimming burrs at welded parts of pipe fittings. Background technique [0002] Debris and very fine microscopic metal particles appear on the surface of metal parts, which are called burrs. In the process of mechanical processing, the pipe fittings need to be welded, and burrs are easy to occur during welding. Due to the burrs in the welding place, it is easy to affect the fit when the pipe fittings are matched, and affect the accuracy of the mechanical parts. The existing method of removing burrs That is, use sandpaper to polish the burrs on the welded part. Because the burrs are hard, they are easy to damage the sandpaper, so it is easy to scratch the hands, causing waste of sandpaper, and it is also laborious. Some use grinding wheels for grinding, which requires a motor Drive the grinding wheel to rotate, thereby wasting electric energy, and the speed of the grinding wh...

In the process of mechanical processing, the pipe fittings need to be welded, and burrs are easy to occur during welding. Due to the burrs in the welding place, it is easy to affect the fit when the pipe fittings are matched, and affect the accuracy of the mechanical parts. The existing method of removing burrs That is, use sandpaper to polish the burrs on the welded part. Because the burrs are hard, they are easy to damage the sandpaper, so it is easy to scratch the hands, causing waste of sandpaper, and it is also laborious. Some use grinding wheels for grinding, which requires a motor Drive the grinding wheel to rotate, thereby wasting electric energy, and the speed of the grinding wheel is fast, and it is easy to polish off the welding point of the welding place, thereby reducing the firmness of the pipe fittings, and it is also inconvenient to grind pipe fittings of different thicknesses, and needs to be replaced. The mold is polished, which increases the cost of use
