Permanent magnetic drilling machine

Abstract

The invention discloses a permanent magnetic drilling machine which comprises a horizontally arranged base, a rack mechanism and a permanent magnetic drilling rig device, wherein the rack mechanism comprises a column, a tank body and a tank sliding mechanism; the permanent magnetic drilling rig device comprises a rotation driving mechanism and a permanent magnetic vibration mechanism; the rotation driving mechanism is connected with the permanent magnetic vibration mechanism in a transmission manner; the permanent magnetic vibration mechanism comprises a main shaft used for mounting a cutter and connected with the rotation driving mechanism in a transmission manner, a permanent magnetic mechanism mounted on the main shaft and used for driving the main shaft to vibrate up and down, and a telescopic movement mechanism sleeving the main shaft; a vibration amplitude adjusting mechanism for adjusting a vibration amplitude of the main shaft is arranged on the tank body. The permanent magnetic drilling machine provided by the invention is simple in structure, reasonable in design and high in reliability, enables the cutter to be in periodical contact with a workpiece to be drilled, increases instantaneous drilling force, reduces drilling temperature, shortens drilling time, and improves surface finish and processing precision of the workpiece to be drilled.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a permanent magnet drilling machine. Background technique [0002] Since the beginning of the new century, our country has entered a new development stage of accelerating socialist modernization. Mechanization shoulders an arduous historical mission. Holes, vertical holes or parallel holes, etc., each country specially develops and develops a variety of drilling machines. Nowadays, there are many types of drilling machines: vertical drilling machines, bench drilling machines, horizontal drilling machines, radial drilling machines, milling drilling machines, etc. Drilling machine is a general-purpose machine tool with a wide range of uses. Drilling machine refers to a machine tool that mainly uses a drill bit to drill on a workpiece. Drilling, reaming and reaming can be performed on the drilling machine equipped with a universal workbench, and boring can...

Problems solved by technology

[0003] With the development of numerical control technology, numerical control machine tools are gradually applied in the field of drilling small diameter holes, but there are still some problems in the numerical control system: dust enters the numerical control device, and floating dust and metal powder easily cause the insulation resistance between components to drop. As a result, failures or even damage to components will occur; in addition, the cooling and ventilation system of the CNC cabinet needs to be cleaned regularly, and the battery used for the memory must be replaced regularly; moreover, the CNC system still needs maintenance when it is not used for a long time, and the CNC system is powered on or the drilling machine is run. increase processing costs and other issues; in addition, currently, the main drilling machine tools used are gun drilling machine, BTA machine tool and spray suction drilling machine tool, among which gun drilling machine tool is the most common drilling machine tool at present, and its cooling and chip removal require pressure aerosol

At present, there are some machine tools for processing small-diameter holes on the market, but their performance is not perfect, and the following problems often occur when processing small-diameter holes: (1) When drilling small holes, it is easy to produce drilling tumors, and the drilling is not easy to discharge. Cause drilling blockage and cause drill bit wear and breakage; (2) The drilling diameter is small, the tool is in continuous contact with the workpiece to be drilled, the heat dissipation during the drilling process is not good, and the drilling temperature is too high, creating conditions for the occurrence of drilling tumors (4) Built-up edge, scales and surface microcracks are easy to occur on the processed surface, which makes the surface finish and geometric accuracy of the workpiece processing not high
