Description

Device for removing bits wound on drill bit

Technical Field

The utility model belongs to the technical field of the machine-building, a clear away drill bit and twine device of bits is related to.

Background

When drilling with a machining center, there is often a phenomenon that chips get entangled on the drill. The usual practice is to pause the machine and clean the cuttings with a gas gun or brush. If the drilling is continued without timely cleaning, the chips become increasingly serious. The upper surface of the workpiece is scratched when the workpiece is light, and the drill bit is broken when the workpiece is heavy.

Disclosure of Invention

The inventor of the invention has been engaged in numerical control machining for many years, and after finding out the problems, the inventor aims to provide a device for removing the drill bit winding scraps, which can automatically remove the drill bit winding scraps of the numerical control machine, ensure the machining precision and prevent the drill bit from being broken.

The utility model discloses a realize that the technical scheme that its purpose was taken is: a device for removing bits wound on a drill bit structurally comprises a support, a chip stroking plate and a fixing screw rod; the support column is made of a steel pipe, the chip smoothing plate is in a V-shaped jaw shape, sharp teeth are distributed in the jaw, and a fixing hole is formed in the tip of the jaw; the fixing screw penetrates through the fixing hole and the inner hole of the steel pipe to fix the chip stroking plate on the top end of the pillar, and the lower part of the fixing screw is fixed with the numerical control machine tool workbench.

Furthermore, the diameter of the outer circle of the steel pipe is phi 30mm, the diameter of the inner hole is phi 14mm, and the length of the steel pipe is 200-300 mm.

The utility model has the advantages that: this device adopts above-mentioned technical scheme, uses under cooperation digit control machine tool presets the procedure, and the bits that can the automatic clear digit control machine tool twine the bits, guarantees the machining precision, prevents the drill bit rupture.

Drawings

FIG. 1 is a schematic view of a device for removing bits from drill bits according to the present invention;

FIG. 2 is a top view of the middle stroking plate of the present invention;

fig. 3 is a cross-sectional view taken along line C-C of fig. 2.

Detailed Description

The invention will be further described with reference to the accompanying drawings and detailed description, the structure and advantages of which will be apparent.

Referring to fig. 1-3, a device for removing bits from drill bits comprises: a support 1, a chip stroking plate 2 and a fixed screw 3; the support 1 is formed by a steel pipe with the outer circle diameter phi of 30mm, the inner hole diameter phi of 14mm and the length of 200-300 mm, the chip stroking plate 2 is in a V-shaped jaw shape, sharp teeth 4 are fully distributed in the jaw, and the tip of the jaw is provided with a fixing hole 5; the fixing screw 3 penetrates through the fixing hole 5 and the inner hole to fix the chip smoothing plate 2 on the top end of the strut 1, and the lower part of the fixing screw 3 is fixed with the numerical control machine tool workbench 6.

Before use, preparation work is required, and the preparation work comprises the following steps:

(1) The device is pressed to one corner of a workbench 6 of a numerical control machine tool by a fixed screw 3;

(2) The drill bit which is easy to be wrapped with chips is called out, the main shaft is manually moved, the drill bit is positioned at the position 100mm away from the opening of the chip stroking plate 2, and the position of the drill bit at the moment is recorded, namely the X, Y value of a workpiece coordinate system; the main shaft is moved downwards, so that the handle of the drill is aligned with the height of the chip stroking plate 2; horizontally moving the main shaft to enable the drill to be positioned in the opening of the chip smoothing plate 2, enabling the distance between the drill handle and the sharp tooth of the chip smoothing plate 2 to be 4mm, paying attention to avoid tool shank interference, and recording the position of the drill at the moment, namely the X, Y, Z value of a workpiece coordinate system;

(3) And programming a program to enable the main shaft to move according to the actions, then reversely rotating at a low speed and lifting to adapt to the lead angle of the spiral groove of the drill bit, and realizing chip removal in the step.

Example program of numerically controlled lathe:

g90 G0X-500 Y250 (the drill moves to the outer side of the opening of the chip stroking plate);

z-80 (drill moves down, shank is aligned with the stroker plate);

y380 (the drill moves in the opening of the chip stroking plate);

g91 G1Z 100F 2000S 300M 4 (the drill bit is reversely rotated and lifted to realize the chip stroking action);

g90 G0Z 300M 5 (bit up, stall);

finally, drilling and performing a chip removal test; sequentially carrying out a chip stroking test on other drill bits according to the steps 2-3; the above procedure can also be implemented by macro instructions to further simplify the programming.

This device adopts above-mentioned technical scheme, uses under the program is preset to the cooperation digit control machine tool, and the bits are twined to the drill bit that can the automatic clear digit control machine tool, need not artificial intervention, prevents the drill bit rupture.
