A base 12 protruding from a bottom surface of the chip collection box 10 and having a fixing shaft 11 protruded at the center of the upper surface thereof;

A rotating body 14 rotatably coupled to the stationary shaft 11 in a clockwise or counterclockwise direction and having a mounting groove 13 formed in the vertical direction at the same angle (at an angle of 120 degrees) ;

(Not shown) dropped onto the chip tray 10 when the coupling piece 15 corresponding to the mounting groove 13 is formed at one end and rotated by the rotation of the rotating body 14, And a blade-type chip collector (17) having a pusher (16) for separating and collecting the pusher (16) at one end.

More preferably, the magnetic chip 19 is further provided with a magnetic body 19 which can be lifted and lowered in a storage space 18 formed in the up-and-down direction in the blade-type chip collector 17, When the magnetic chips 19 adhered to the outer surface of the collector 17 are moved to the upper end of the storage space 18, the magnetic chips can be removed from the chip collector 17 as the magnetic force is removed.

The chip collector 17 shown in FIGS. 1 to 4 is shown to open outward from the center in order to clearly show the state in which the magnetic substance 19 is stored in the storage space 18. However, It is preferable that the open portion of the illustrated chip collector 17 is closed and the lifting means of the magnetic body 19 is provided in order to prevent the chip from flowing into the inside. The means for raising and lowering the magnetic body 19 can be an electric device, and a means for raising and lowering it manually may be provided.

Even if an arbitrary obstacle is arranged on the fixed shaft 11 provided in the chip collection box 10 so that the rotating body 14 can be rotatably engaged with the fixed shaft 11, 14 are divided into first and second rotating bodies 20 and 21 by the first and second rotating bodies 20 and 21 being wrapped around the outer surface of the rotating shaft 11, The first and second concave and convex portions 22 and 23 are fitted by the first and second concave and convex portions 22 and 23 formed to correspond to each other, , And a fixing member (for example, a fixing pin can be used) penetrating the hole.

The mounting groove 13 formed in the rotating body 14 is formed in a Dovetail groove or T shape so that the wing type chip collector 17 can be detachably coupled to the rotating body 14. The chip collector 17 is detached from the mounting groove 13 of the rotating body 14 and then the coupling piece 15 of the new chip collector 17 can be fitted to the mounting groove 13 to be replaced have.

So that the frictional force of the rotating body 14 rotated on the base 12 can be reduced

A ball bearing 25 is mounted on the bottom surface of the rotating body 14 such that the ball bearing 25 partially protrudes while maintaining a constant spacing in the circumferential direction and the ball bearing 25 rotates when the rotating body 14 is rotated Is formed by being recessed at the edge of the flange (27) of the base (12).

And is mounted in a clearance between the bottom surface of the rotating body 14 and the upper surface of the flange 27 so as to prevent foreign matter such as cutting chips or cutting oil of the chip hopper 10 from flowing into the ball bearing 25 side through the gap. and a sealing body 28 in the form of a washer. The sealing member 28 is formed with a cutout (not shown) on one side thereof so as to be openably engaged with the side surface of the stationary shaft 11.

Hereinafter, use examples of a milling machine chip collecting apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in Figs. 1 to 4, when a workpiece is dry-worked by a milling cutter or an end mill which is replaceably mounted on a head by clamping and fixing the workpiece to a vise mounted on a table of the milling machine, The chip is dropped onto the chip collection box 10.

On the other hand, when the workpiece is wet-worked by the end mill, the cutting oil sprayed to the workpiece and the cutting tool through the nozzle drops onto the chip collection box 10.

Here, the technical contents of the chip collection box 10 for collecting the cutting chips and the cutting oil that are dropped during the cutting process of the workpiece for dry processing or wet processing of the workpiece fixed to the vice are described in the related art. Will not be described in detail.

As described above, the cutting chips generated during the cutting process fall on the chip collecting box 10 and accumulate. As a result, when the workpiece is wet-processed, a large amount of cutting oil falls on the chip.

Accordingly, when cutting chips are piled up on the chip collection box 10 from the workpiece, the chip can be easily collected by collecting the chips into one place as the wing chip collector 17 described above is rotated.

That is, when the chip collector 17 provided at the equal interval in the circumferential direction is rotated clockwise or counterclockwise on the rotating body 14, the chips dropped on the chip tray 10 are transferred to the chip collector 17 It is scraped in one direction by the pusher 16.

At this time, since the chip collector 17 is spaced from the bottom surface of the chip collection box 10, when the chips of the chip collection box 10 are collected in one direction by the rotation of the chip collector 17, In the course of moving the cutting chip, the cutting oil can be separated from the cutting chip. The cutting oil separated from the cutting chip by the rotation of the chip collector 17 is collected to one side through a through hole (not shown) formed at one side of the chip recovery box 10 and reused.

When the chip collector 17 mounted on the rotating body 14 is rotated in order to separate the cutting chips dropped on the chip collecting box 10 from the cutting oil and collect them in one place as described above, The frictional force of the rotating body 14 can be minimized by the ball bearing 25 mounted between the flange 27 of the base 12 and the upper surface of the flange 27 of the base 12.

Therefore, the rotational force for rotating the chip collector 17 by the operator in order to scrape off the chips accumulated in the chip collection box 10 can be reduced.

A clearance is formed between the bottom surface of the rotating body 14 and the upper surface of the flange 27 due to the mounting of the ball bearing 25 and the washer- Can be prevented from being introduced into the ball bearing 25 through the clearance.

When the chip collector 17 is rotated as described above, the chip of the chip collection box 10 is different from the outer surface of the pusher 16 by the magnetic force of the magnetic body 19 embedded in the pusher 16 of the chip collector 17 Respectively.

At this time, the magnetic body 19 of the pusher 16 is moved from the lower end to the upper end of the storage space 18 when the amount of cutting chip sticking to the outer surface of the pusher 16 is large, The chip can be removed.

That is, the magnetic body 19 located on the bottom surface of the storage space 18 is moved to the upper side along the storage space 18 by using its handle (not shown). Therefore, the magnetic force of the magnetic body 19 is removed at the lower end of the storage space 18, so that the chip attached to the outer surface of the lower end of the pusher 16 of the chip collector 17 can be easily removed.

After the cutting chips adhering to the outer surface of the pusher 16 are removed, the magnetic body 19 positioned at the upper end of the receiving space 18 is moved to the lower end along the receiving space 18. [

On the other hand, even if a milling machine (milling machine, etc.) has already been delivered and an arbitrary obstacle is arranged on the fixed shaft 11 installed in the chip collection box 10, the rotating body 14 is rotated on the fixed shaft 11 The entire body 14 can be rotatably engaged.

That is, the first and second rotors 20 and 21 having the first and second rotors 20 and 21 are formed in close contact with each other so as to surround the outer surface of the stationary shaft 11, After the concave and convex portions 22 and 23 are fitted to each other, the first and second concave and convex portions 22 and 23 are coupled by the coupling member 24 coupled to the coupling hole (not shown) formed in the first and second rotors 20 and 21, (22, 23) can be fixed.

4, the illustrated cutting chips are shown as being viewed by projecting the collecting device for the sake of understanding, and therefore it should not be misunderstood that the cutting chips are directly attached to the magnetic body 19. [
