Polishing brush for curved surface board and plane board

Abstract

The invention discloses a polishing brush for a curved surface board and a plane board. The polishing brush comprises a rotary drum, polishing abrasive cloth, brush bars, a nut and a screw. One side edge of the polishing abrasive cloth is connected with the outer wall of the rotary drum, the connecting edges of the polishing abrasive cloth and the rotary drum are parallel to the axis of the rotary drum, and the bottom edges of the brush bars are connected with the outer wall of the rotary drum and are parallel to the axis of the rotary drum. The polishing abrasive cloth and the brush bars are alternately arranged. The screw penetrates through a center shaft of the rotary drum, the nut is mounted on the screw, and the rotary drum is tightly pressed between the nut and the head of the screw. The polishing brush can be used for polishing the curved surface board, a concave line groove and a convex line, the polishing effect is good, the polishing abrasive cloth is convenient to replace, the cost performance is high, economy and environment protection are realized, the boards can be protected, operation and transportation are convenient, and the working efficiency is high.

Description

technical field [0001] The invention relates to a grinding brush, in particular to a grinding brush for curved surfaces and plane boards, which is especially suitable for grinding curved surfaces, grooves and convex lines. Background technique [0002] The existing grinding brushes directly connect the abrasive wires to the turntable or drum, not only the grinding effect is not good, the wires are used up, but the entire flower head including the shaft and the iron handle must be discarded, resulting in a waste of national resources. Economical, not environmentally friendly. in addition. The iron handle combined with the current grinding brush and the motor is fixed, which is not conducive to handling; and the iron handle cannot exceed 4.5 cm, which is not convenient for workers to operate. If it is to be lengthened, the requirements for abrasive tools are high and the cost is high. [0003] Therefore, when the grinding precision is required to be high, it is still general...

AI Technical Summary

Problems solved by technology

The iron handle combined with the current grinding brush and the motor is fixed, which is not conducive to handling; and the iron handle cannot exceed 4.5 cm, which is not easy for workers to operate. If it is to be lengthened, the requirements for abrasive tools are high and the cost is high

[0003] Therefore, when the grinding precision requirements are high, it is still common to use hand-grasped emery cloth to polish the curved plank. The disadvantages are obvious, labor is wasted and the polishing effect is not good enough, and it is impossible to quickly polish the curved plank, grooves and convex lines.
