Brush drilling mechanism used for drilling inverted-T-shaped hole and drilling method

Abstract

The invention discloses a brush drilling mechanism used for drilling an inverted-T-shaped hole, and relates to the brush drilling mechanism. The brush drilling mechanism comprises a bottom plate, a first supporting base, a second supporting base and a V-shaped pull rod, wherein a power shaft is arranged on the first supporting base; the power shaft passes through one end of the first supporting base, and is equipped with a first eccentric wheel; one end of the V-shaped pull rod is hinged with the first eccentric wheel through a connecting rod; the other end of the V-shaped pull rod is hinged with a clamping plate through a V-shaped pull rod fixed shaft; the right lower part of the bottom plate is equipped with a motor fixed plate; an eccentric motor is fixedly arranged on the motor fixed plate; the output shaft of the eccentric motor is connected with a second eccentric wheel; the second eccentric wheel is fixedly connected with a cam shaft; and the cam shaft is fixedly connected witha swing plate through a connecting plate. The brush drilling mechanism is small in labor intensity of a worker, and further improves efficiency. The invention further discloses a drilling method of the brush drilling mechanism used for drilling the inverted-T-shaped hole.

Description

technical field [0001] The invention relates to a brush drilling mechanism, more specifically a brush drilling mechanism for drilling inverted T-shaped holes. The invention also relates to a drilling method of the brush drilling mechanism used for drilling inverted T-shaped holes. Background technique [0002] Such as Figure 8.1 and Figure 8.2 Drill holes in the existing hair brush, as shown in the structure schematic diagram of the bristles and horse nails, the vertical section of the hole drilled in the existing hair brush is rectangular. In this hairbrush, the maximum tensioning force only has 10-20 kilograms, and there is no hairbrush with tensioning force exceeding 20 kilograms at present. After long-term use of this kind of hair brush, the bristles will fall off or the horse nails will fall off. [0003] Horse nails are generally not used for large brushes. For example, the brush disc of a disc glass brush can only be artificially planted, which has extremely low...

AI Technical Summary

Problems solved by technology

For example, the brush disc of a disc glass brush can only be artificially planted, which has extremely low labor efficiency, and it is difficult to recruit workers for this type of work. One person can only plant the wool on one disc glass brush per day (circular The diameter of the disc glass brush disc is 1.2 meters), and the wool material fixed by artificial wool planting method will not exceed 20 kg. Disc scrap

There are also situations where the wool is put into the pores by manual hammering and then fixed with a pull wire. In this case, the tension force is not high.
