Problems solved by technology

[0003] Existing drilling machines use manual control to control the axial feed of the drill bit. Because the control force of the manual feed method is not easy to control, the feed speed is sometimes fast and sometimes slow, and the quality of the drilled holes is poor.

Abstract

The invention relates to a simple drilling machine. The simple drilling machine comprises a base, a drill bit, a motor and a workpiece support. An output shaft of the motor is connected with the drill bit through a chuck, the workpiece support is fixed on the upper surface of the base, guide columns are arranged on the base, support springs are sleeved with the guide columns, a lower support plate is slidably matched on the upper portion of the guide columns, the support springs support the lower support plate, the motor is fixed on the lower support plate, an upper support plate is fixed at the upper ends of the guide columns, an air cylinder is arranged on the upper support plate, the upper support plate is provided with a through hole, and a piston rod of the air cylinder penetrates the through hole to be connected with the lower support plate. Feed speed and force control of the drill bit can be controlled uniformly.

Description

technical field [0001] The invention relates to a simple drilling machine. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in a workpiece. Generally, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively high machining accuracy. It can drill through holes and blind holes, replace special tools, expand, countersink, ream or tap. During the machining process, the workpiece does not move, let the tool move, align the center of the tool with the center of the hole, and make the tool rotate (main movement). The characteristic of the drilling machine is that the workpiece is fixed and the tool rotates. [0003] Existing drilling machines use manual control to control the axial feed of the drill bit. Because the control force of the manual feed method is not easy to control, the feed speed is ...
