Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically a horizontal drilling mechanism for vertical and horizontal double-sided drilling and tapping machines. Background Technology

[0002] The horizontally positioned spindle of the horizontal drilling machine is suitable for machining larger and longer workpieces. Its horizontal structure provides stable support for the workpiece, preventing hole position deviations caused by displacement during machining. It is especially suitable for batch processing of long and narrow workpieces such as doors, windows, and bed frames. It adopts precision ball screw transmission and servo motor drive, and the hole positioning error can be controlled within ±0.15 mm. The drill bit can be fed vertically or horizontally to ensure uniform hole diameter and flat hole bottom, improving the smoothness of subsequent assembly. The worktable height is suitable for standing operation, eliminating the need to bend over. The feed handle position conforms to hand exertion habits, and some models are equipped with a foot switch, allowing both hands to hold the workpiece while operating, hence its widespread use.
