Description

A clamping device for bench drill

Technical Field

The utility model relates to the technical field of mechanical processing, in particular to a clamping device for a bench drill.

Background Art

The bench drilling machine is also called bench drill for short. It is a small hole processing machine with a compact size and easy operation. It is usually installed on a special workbench. The drilling diameter of the bench drilling machine is generally less than 13 mm, and the maximum does not exceed 16 mm. The spindle speed change is generally achieved by changing the position of the V-belt on the conical pulley, and the spindle feed is manually operated. At present, bench drills are widely used in the manufacturing field.

Although the existing bench drill is equipped with a clamping workbench, the original clamping workbench has problems such as poor clamping reliability and easy sliding of the workpiece, which can easily lead to the scrapping of the workpiece or damage the drill bit, resulting in material waste and even personal injury.

To this end, we propose a clamping device for a bench drill.
