Milling and drilling machine for table board

Abstract

The invention discloses a milling and drilling machine for a table board and belongs to the field of industrial machinery technology. The milling and drilling machine for the table board includes the four following parts: firstly, a main frame, a positioning table, and a clamping part which comprises a bottom frame with a clamping structure and a three-dimensional positioning table, secondly, an executive mechanism and a drive part which comprises three gear motors used to drive the positioning table and a permanent magnet brushless motor rotating at high speed with a milling cutter, thirdly, a power supply system part needing 220v alternating currents to access, a linear regulated power supply with a 12v fixed output to power for a control system and the executive mechanism, and fourthly, a control system adopting a 8 BIT microcontroller which is connected with an input equipment and an output equipment as the control core. The permanent magnet brushless motor and an end mill are adopted as a mechanical cutter system of the cutting equipment so that a precise positioning system which can be controlled in various ways is available to the mechanical cutter system; therefore, the milling and drilling machine for the table board is simple in structure and applicable to a man-machine interactive system controlled by a milling cutter. At the same time, a novel clamping device is adopted to ensure that the table board is processed without vibration, thereby guaranteeing the safety of the table board.

Description

technical field [0001] The invention relates to a desktop plate drilling and milling machine, which belongs to the technical field of industrial machinery. Background technique [0002] At present, the equipment used in the advanced processing of plates is mainly drilling machines, milling machines, drilling and milling machines or laser cutting equipment. Drilling and milling machines use high-speed moving milling cutters or drills to scrape the plate, so that the part of the target workpiece that should not be left is removed. The platform or milling cutter (drill, etc.) that fix the workpiece can be moved with precise position to ensure that the machine tool scrapes the material accurately. Existing drilling and milling machines have strong processing ability and high processing precision, and can perform complex processing on various materials including hard metals. However, these machine tools are bulky, huge, and costly; they are not flexible enough for general cutti...

AI Technical Summary

Problems solved by technology

But laser cutting is only suitable for some soft materials

At the same time, the laser cutting operation is complicated, and any processing needs to input digital processing drawings in a specific format to proceed

And the cost of laser cutting equipment is very high

The high-energy laser of laser cutting equipment is dangerous, and the volume of the workpiece that can be processed is relatively limited

[0004] In addition, these two processing equipment may have large vibrations when processing plates, which may cause damage to PCB and other types of plates.
