Description

Technical Field

[0001] The utility model relates to the technical field of bench drills, in particular to a bench drill which is convenient for replacing a drill bit. Background Art

[0002] The bench drilling machine is called bench drilling for short. It refers to a small drilling machine that can be placed on the workbench and has a vertical spindle arrangement. The diameter of the hole drilled by the bench drilling machine is generally less than 13 mm and generally does not exceed 25 mm. The speed change of the spindle is generally achieved by changing the position of the V-belt on the tower pulley, and the spindle feed is manually operated. The bench drilling machine is a widely used small drilling machine. The motor drives the wheel through a five-stage speed change, so that the spindle can be changed to five speeds. The head frame can move up and down on the round column and can be rotated to any position around the center of the round column for processing. After adjusting to the appropriate position, it is locked with a handle. If the head frame needs to be lowered, first adjust the safety ring to the appropriate position, lock it with a set screw, then loosen the handle, let the head frame fall to the safety environment by its own weight, and then tighten the handle.
