The polishing tool for polishing the arc angle has the advantages that the abrasive paper with worn or damaged edges can be reused, special-shaped positions, curved surfaces and gaps on furniture or wood products can be polished, the polishing efficiency is high, and the resource waste is reduced; the technical problems that sand paper on a grinding machine in the prior art needs to be replaced after the edge of the sand paper is worn or damaged, the waste rate of the sand paper is very high, a common grinding machine cannot grind special-shaped parts, curved surfaces and gaps on furniture or wooden products, the sand paper needs to be manually used for grinding, and the grinding efficiency is low are solved.
The technical problems of the utility model are solved by the following technical scheme: the utility model provides a grind and throw instrument for polishing circular arc angle, includes the drive shaft, drive shaft one end be equipped with the driving piece, the other end of drive shaft is equipped with the piece of polishing, the piece of polishing includes the crisscross stack of a plurality of layers of paper of polishing, all buckles to the center on every paper of polishing and has a plurality of curved arc of polishing. During assembly, round sand paper which cannot be normally used due to abrasion is cut at the edges and then bent towards the center to form a polishing arc, a plurality of sand paper is overlapped and sleeved outside the driving shaft in a staggered mode, the driving piece can drive the driving shaft and the polishing paper to rotate at a high speed, the polishing paper can polish special-shaped parts on some furniture, such as curved surfaces or gaps, the parts which cannot be polished by the conventional sand paper can be polished, the waste sand paper is reused, and the resource waste is saved while the working efficiency is improved.
Preferably, the polishing paper is flexible and bendable polishing paper. The flexible abrasive paper can be bent to form an arc-shaped polishing arc, so that the flexible abrasive paper can be better polished to curved surfaces or groove seams on some furniture, and the rigid abrasive paper cannot be bent and cannot meet the use requirements.
Preferably, the layers of polishing paper on the driving shaft are spirally overlapped together. The spiral overlapping of the paper of polishing of a plurality of layers is in the same place, can increase the efficiency when polishing, and the efficiency is lower when polishing of the paper of polishing of individual layer, and the spiral overlapping of the paper of polishing of multilayer can increase efficiency and the effect of polishing together.
Preferably, the two sides of the polishing paper are symmetrically provided with gaskets, the two sides of the polishing paper are also provided with locking nuts for clamping the gaskets and the polishing paper, and the locking nuts are matched with the driving shaft through threads. During installation, a plurality of layers of polishing paper are overlapped and sleeved outside the driving shaft, then the gaskets are clamped on two sides of the polishing paper, the gaskets and the polishing paper are clamped through the locking nuts, and finally the driving shaft is installed on the driving piece for use.
Preferably, the polishing paper on the driving shaft is 3 layers. The number of layers of the polishing paper and the angle of spiral staggering can be adjusted according to actual conditions, and the utility model uses 3 layers of polishing paper to be overlapped together as an example, wherein 3 layers of polishing paper are spirally overlapped together, and each polishing paper is symmetrically bent with 4 polishing arcs, so that the polishing paper can be rapidly polished to curved surfaces or grooves on some furniture or wooden products.
Preferably, the driving member comprises a gun body connected with the driving shaft, and a motor head connected with the driving shaft is arranged on the gun body. The driving piece is used for driving the driving shaft and the polishing paper to rotate at a high speed, the gun body and the motor head are of an integral device, the device is of an existing structure, and the assembled polishing paper and the driving shaft can be used only after being installed on the motor head.
Preferably, the driving member further comprises a control switch mounted on the gun body. The control switch is used for controlling the stop of the motor head, further controlling the rotation and stop of the driving shaft and the polishing paper, and facilitating the operation and control.
Therefore, the polishing tool for polishing the arc angle has the following advantages: the edge worn or broken sand paper can be reused, and the polishing arc formed after the old sand paper is bent can polish the special-shaped, curved surface and groove seam on furniture or wood products, so that the polishing efficiency is high, and the resource waste is reduced.
