Description

Drilling and grinding device

Technical Field

The utility model belongs to the technical field of the work piece processingequipment, concretely relates to bore and grind device.

Background

After the workpiece is drilled, in order to avoid the situation that the using effect is poor due to burrs on the hole wall of the drilled hole, the drilled hole needs to be polished, and the burrs on the hole wall are removed, so that the using effect of the workpiece is guaranteed.

In the early polishing mode, a worker polishes the drilled hole by using abrasive paper, the operation is troublesome, the efficiency is low, and the stability of the polishing quality is difficult to ensure. To improve efficiency, a sanding device (also known as Kong Moji) has emerged. However, the existing polishing devices are all handheld, the shape of the existing polishing devices is similar to that of a small inflator, and during operation, a worker needs to hold a workpiece with one hand and hold the polishing device with the other hand to punch a hole in the workpiece. Because grinding device has certain weight and during operation can vibrate, the condition of taking unstability or even taking off the hand appears easily, and then leads to the stability of polishing not enough, except this, grinding device takes off the hand still can lead to the incident.

Therefore, a drilling and grinding device is needed, which can stably and safely grind the drilled hole on the workpiece.
