Drilling equipment capable of automatically controlling drilling depth

Abstract

The invention discloses drilling equipment capable of automatically controlling the drilling depth. A detection unit tests the inlet depth of a drill bit and automatically feeds the depth back to a numerical control unit. When the numerical control unit determines that the actual depth of the drill bit reaches a first preset position, the drill bit is notified of reducing the rotating speed of the drill bit to ensure that the drilling position is not shifted. When the numerical control unit determines that the actual depth of the drill bit reaches a second preset position, the rotating speed of the drill bit is increased and returned to a normal state. When the actual depth of the drill bit reaches a third preset position, the rotating speed of the drill bit is reduced. When the actual depth of the drill bit reaches a designated depth, the drill bit stops, then, the drilling depth can not be too large or too small, and the drilling depth is accurate.

Description

technical field [0001] The invention relates to the technical field of drilling processing, in particular to a drilling device with automatic control of drilling depth. Background technique [0002] Drilling machine is a general term for machinery and equipment that leaves cylindrical holes or holes on the target by means of rotary cutting or rotary extrusion using tools that are harder and sharper than the target, also known as drilling rigs and punching machines , Drilling machine or through hole machine, etc. When drilling some precision products, it is necessary to drill to a precise hole depth. For ordinary drilling machines, you can only stop and observe after drilling to a certain depth to prevent the drilling from being too deep or not deep enough. [0003] In order to improve work efficiency and the accuracy of drilling depth, a CNC automatic drilling machine has appeared. The drive motor of the drill bit is electrically connected to the CNC unit, and the data of t...

AI Technical Summary

Problems solved by technology

[0004] Although the existing numerical control technology can improve drilling efficiency and hole depth accuracy to a certain extent, since the drill bit rotates at high speed from the start of drilling to the completion of drilling, it may occur when the drill bit touches the surface of the material to be processed. Offset, resulting in inaccurate drilling locations; may be deeper or shallower at the point where the drilling is completed, resulting in inaccurate drilling depths
