Abstract

The invention discloses an embedded system-based threaded hole numerical control drilling machine and a control method. The embedded system-based threaded hole numerical control drilling machine is characterized in that an infrared distance measuring sensor is arranged on a chassis, a torque sensor is electrically connected to the rotating shaft of a main motor, and both the infrared distance measuring sensor and the torque sensor are respectively connected with different input / output ports of a microprocessor. The control method disclosed by the invention adopts an upper computer graphical control method, processing depth can be controlled as the infrared distance measuring sensor is arranged, the scraps in a machined hole can be sucked as a miniature dust collector is arranged, thus the breakage of a screw tap caused by the fact the screw tap is stuck by the scraps can be prevented, as the embedded technology is adopted, the drilling machine can be directly controlled by an upper computer to carry out screwing operation on workpieces, thereby realizing human-machine interaction, tedious work of the staff can be decreased through performing screwing operation on the workpieces by the computer, and the rotation speed of the motor can be controlled by the computer, therefore the screw tap is protected and the thread quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of drilling machines, and in particular relates to a threaded hole numerical control drilling machine and a control method based on an embedded system. Background technique [0002] Drilling machine is one of the equipments for drilling workpieces. It generally includes a base, a column vertically fixed on the base, a spindle seat fixed on the column, a spindle vertically fixed on the spindle seat, and a motor that drives the spindle to rotate through a transmission mechanism. And the operating mechanism that drives the spindle to move up and down to drill holes. [0003] Chinese Patent Application No. 201020624200.1 discloses a drilling machine with threading function. The rotating speed of the rotary head of the drilling machine is fixed, and the hardness of different workpieces is different. If the drilling speed of the tap is too slow, the workpiece cannot be threaded. If the drilling speed of the tap i...
