Abstract

The invention discloses a drill feeder of an automatic drilling machine. The drill feeder comprises a spline housing connected with an output shaft of a motor, and a spline shaft coaxially connected with the spline housing in a sliding way, wherein the other end of the spline shaft is coaxially connected with a drill by a drill chuck, and a shaft sleeve is sleeved with the middle of the spline shaft; and the two ends of the shaft sleeve are connected with the spline shaft by bearings, and the shaft sleeve is connected with a driving component capable of driving the spline shaft to axially move. Since the drill provided by the invention can feed or retract along the axial direction, and the whole process is controlled by a controller, the drilling efficiency is high, the drilling position is precise, the labor intensity of works can be reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of drilling machinery, and in particular relates to a drill feed device for a drilling machine used by a special drilling machine for drilling coils of refrigeration equipment. Background technique [0002] The heat exchange coil used in the current absorption-diffusion refrigeration equipment needs to drill two holes at specific positions on the coil to connect the balance pipe and the thin liquid pipe respectively. At present, the coil is generally drilled with a hand drill Drilling is inefficient, and it is inconvenient to manually position the coil due to the irregular shape of the coil. Contents of the invention [0003] The object of the present invention is to propose a drill feed device for a drilling machine used in a special drilling machine for drilling coils of refrigeration equipment, so as to overcome the low efficiency of using hand drills to drill coils in the prior art .
