Stepless speed regulation electric feeding drilling machine and control method therefor

Abstract

The invention relates to a stepless speed regulation electric feeding drilling machine and a control method therefor, and belongs to the technical field of stepless speed regulation drilling machines. The drilling machine comprises a vertical drilling machine which is integrally arranged, wherein the vertical drilling machine sequentially comprises a stand column fixed on a base, a workbench movably arranged on the stand column and a machine head box positioned at the top end of the stand column from bottom to top; the workbench is horizontally fixed on the upper surface of a stepping motor I, and a rotating shaft of the stepping motor I matches sawteeth on the side portion of the stand column by means of a gear and drives the workbench positioned thereon to move up and down along the stand column; the machine head box is completely flush with the rear portion of the base, and the machine head box and the base are attached to a wall at the same time; and a stepping motor II is arranged on the side portion of the machine head box, and the stepping motor II drives a drill bit positioned below the machine head box by means of a belt wheel. According to the drilling machine, an alternating current servo motor is used to replace a traditional belt pulley and a traditional machine head box, constant torque stepless speed regulation is achieved, the size of the machine head box is reduced, and after simplification, the rear portion of the machine head box and the rear portion of the drilling machine base can be attached to the wall at the same time.

Description

technical field [0001] The invention relates to a stepless speed regulation electric feed drilling machine and a control method thereof, belonging to the technical field of stepless speed regulation drilling machines. Background technique [0002] At present, when the drilling machine is operated, the handle needs to be pressed down to drive the drill spindle down to complete the drilling of the workpiece on the workbench. When the thickness of the workpiece does not match the drilling distance, the height of the workbench needs to be manually adjusted to a suitable position and The relative position of the locking work and the column, this process is frequently manually adjusted, which is inefficient, inaccurate, and also has potential safety hazards. In addition, due to the complex structure of the head box of the traditional belt drive, the rear of the head box and the rear of the base cannot be completely flush, that is, the two cannot be attached to the wall at the same...

[0002] At present, when the drilling machine is operated, the handle needs to be pressed down to drive the drill spindle down to complete the drilling of the workpiece on the workbench. When the thickness of the workpiece does not match the drilling distance, the height of the workbench needs to be manually adjusted to a suitable position and The relative position of the locking work and the column, the process is frequently adjusted manually, which is inefficient, inaccurate, and also has potential safety hazards

In addition, due to the complex structure of the head box driven by the traditional belt, the rear of the head box and the rear of the base cannot be completely flush, that is, the two cannot be attached to the wall at the same time, and there is also inconvenience in use and the risk of tipping
