Pneumatic permanent magnet magnetic drill

Abstract

The invention relates to a magnetic drill and discloses a pneumatic permanent magnet magnetic drill. The pneumatic permanent magnet magnetic drill comprises a magnetic seat, and a body which is fixed on the magnetic seat. The body is connected with a main shaft case which is connected with a pneumatic motor for driving; the pneumatic motor is arranged on the main shaft case; and the magnetic seat is a permanent magnet seat. Due to the adoption of the technical scheme, compared with the traditional magnetic drills, the pneumatic permanent magnet magnetic drill has the remarkable advantages of stable magnetic force, no electric shock or burnout, stepless speed regulation, and applicability for power supply free environment, and the like.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a magnetic base drill. Background technique [0002] The existing magnetic base drill mainly uses the magnetic base of the electromagnet at the bottom of the machine itself, which generates magnetism after power-on, and the magnetic base is adsorbed on the steel part, which is convenient for drilling the workpiece, so that when the workpiece needs to be drilled, there is no need to use it. Machine problem. [0003] At present, most of the magnetic base drills on the market use electric motors. This type of magnetic base drill needs power supply to make the magnetic base drill work. This type of magnetic base drill cannot be used in an environment without power supply. In addition, electric motors are relatively easy to burn out when used, there is a risk of electric leakage and electric shock, and it is difficult to realize stepless speed regulation. [0004] In addition...

Problems solved by technology

[0003] At present, most of the magnetic base drills on the market use electric motors. This type of magnetic base drill uses power supply to make the magnetic base drill work. This type of magnetic base drill cannot be used in an environment without power supply.

In addition, electric motors are relatively easy to burn out when used, there is a risk of electric leakage and electric shock, and it is difficult to realize stepless speed regulation

[0004] In addition, the magnetic base of the traditional magnetic base drill is fixed by an electromagnetic structure, and it is also required to be used in an environment with a power supply.

The magnetic base drill adopts the electromagnetic structure fixing method. When drilling metal parts, in addition to the hidden danger of electric shock, when drilling in a horizontal state or upside down, there is also the danger of the magnetic base drill falling down when a power failure or electrical accident occurs.
