Problems solved by technology

In view of this situation, in some current drilling machine designs, permanent magnets are set around the drill bit, so that the debris (mostly iron filings) generated by the workpiece processing can be sucked away by the permanent magnets to prevent them from flying around; however, This kind of design still needs to spend a lot of effort to clean up the debris adsorbed on the surface of the permanent magnet after the drilling machine is shut down, and it also needs to spend a lot of energy

Embodiment 1

[0017] The embodiment of this electromagnetic dustproof drilling machine is as figure 1 As shown, it includes a main machine (not shown), the main machine is provided with a main shaft 1, and the main shaft 1 drives the drill seat 2 to rotate; the drill seat 2 is equipped with a drill bit 21 extending downward; the drill seat An annular seat 3 surrounding the drill seat 2 is also fixed on the 2, and permanent magnets 31 uniformly distributed around the axis of the drill seat are arranged in the annular seat 3; Seat 4, the induction seat 4 can freely rotate around the axis of the drill seat relative to the annular seat 3; the induction seat 4 is provided with an induction coil 41 uniformly distributed around the drill seat 2; in the first embodiment, each The permanent magnet 31 is in the shape of a vertical bar, and the magnetic pole is vertically downward; each of the induction coils 41 is a planar coil arranged horizontally; The magnetic lines of force produced by the magne...

Embodiment 2

[0021] Embodiment two of this electromagnetic dustproof drilling machine is as figure 2 As shown, the difference from the first embodiment is that the induction seat 4 in the second embodiment is surrounded by the outer circumference of the annular seat 3, and constitutes a bearing mechanism with the annular seat 3; the annular seat 3 is used as the inner bearing of the bearing mechanism The induction seat 4 is used as the outer ring of the bearing mechanism. At this time, the permanent magnet 31 is arranged horizontally and magnetized along the horizontal direction; the induction coil 41 is a planar coil arranged vertically; The magnetic field lines generated by the magnetic poles of the permanent magnets 31 pass through the induction coils 41 in sequence.

[0022] In addition, in the second embodiment, the end of the curved rod 5 is also provided with a lighting lamp head 6, which is connected in parallel with the electromagnet 51, so as to illuminate the working position ...

Abstract

The invention provides an electromagnetic dust prevention drilling machine. According to the technical scheme, a spindle of the drilling machine drives a drill bit seat to rotate, and a drill bit which extends downwards is assembled on the drill bit seat; an annular seat surrounding the drill bit seat is further fixed on the drill bit seat, permanent magnets which are uniformly distributed aroundthe axis of the drill bit seat are arranged in the annular seat, and an induction seat is further rotationally connected on the annular seat, and can freely rotate; induction coils which are uniformlydistributed around the drill bit seat are arranged in the induction seat; in the process that the induction seat rotates relative to the annular seat by a circle, magnetic force lines generated by magnetic poles of all the permanent magnets penetrate through the induction coils in sequence; and bent rods which are bent to the middle-upper part of the drill bit are uniformly distributed on the lower part of the induction seat in a circumferential direction, and electromagnets which are electrically connected with the induction coils are arranged in the bent rods. According to the drilling machine, in the machining process, scraps generated by a workpiece can be massively absorbed, and automatically falls from the surface of the workpiece after the drilling machine is stopped, so that the scraps are prevented from flying freely, and the scrap clearing difficulty is also reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a drilling machine. Background technique [0002] Drilling machine is a commonly used mechanical processing equipment. During the processing, the drill bit rotates at high speed, causing a large amount of debris in the drilled hole formed on the workpiece to rise, which not only puts the operator in a relatively harsh working environment, but also makes the workpiece After processing, it is also necessary to clean a large area around the drilling machine. In view of this situation, in some current drilling machine designs, permanent magnets are set around the drill bit, so that the debris (mostly iron filings) generated by the workpiece processing can be sucked away by the permanent magnets to prevent them from flying around; however, This kind of design still needs to spend a lot of effort to clean up the debris adsorbed on the surface of the permanent magnet afte...
