Description

Technical Field

[0001] The utility model relates to the technical field of furniture processing, in particular to a three-row drill. Background Art

[0002] In the production and processing of furniture panels, three-row drills are often required for batch drilling. As the name suggests, a three-row drill is a drilling device composed of three rows of drill bits, which can drill holes in multiple areas of the panel at one time.

[0003] A Chinese patent discloses a three-row drill for wood processing (authorization announcement number CN220614319U), and its specification discloses that "the movement of the electric slider will cause the connecting plate to move with the fixed block, so that after the drill bit slides to the required position, the cylinder one is started, thereby driving the drill bit base to move downward to drill the plate. By starting the cylinder two, the clamp piston rod can be moved to the left or right. When the drill bit needs to be replaced, the cylinder two can drive the clamp piston rod to move to the left, so that the clamp piston rod leaves the slot. At this time, the drill bit is removed for replacement, and the clamp piston rod is driven by the cylinder two to enter the slot, so that the drill bit can be fixed, thereby making the replacement of the drill bit more convenient and quick." However, according to common sense, although the cylinder can be extended and retracted, the extension amount is difficult to control accurately. That is to say, when the above-mentioned cylinder one is extended, although it can drive the drill bit to move downward for drilling, its drilling depth is difficult to control accurately, which will affect the drilling accuracy of the plate.
