Abstract

PROBLEM TO BE SOLVED: To prevent removed burrs from being scattered by press fitting a rod-shaped work which has burrs on its circumferential surface and whose outer diameter is approximately equal to the inner diameter of a blade part of a deburring tool from the upper end side of a through hole of the deburring tool by an appropriate means. SOLUTION: The tip of a work W is inserted in a through hole 33 of a deburring tool 30. The work W enters the through hole 33 and further a shaft hole 11 of a base 10, and its tip is supported by a supporting tool 20. The work W is pushed out by operating a pressing tool 40 by a piston/cylinder mechanism 50, and press fitted to the through hole 33, and burrs B of the work W are advanced into the through hole 33 while they are cut by a blade part 341 of the through hole 33. A compressive spring 21 is compressed. After burrs B are removed, the operation of the pressing tool 40 to allow the work W to be returned to the initial condition by the elasticity of the compressive spring 21.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deburring apparatus and a deburring tool used in this apparatus, and more particularly to a deburring apparatus for deburring a rod-shaped work having a burr on its peripheral surface.

[0002]

2. Description of the Related Art Conventionally, in order to remove this type of burr, the peripheral surface of the work is pressed against a separately rotating wire buff while slowly rotating the work around its axis.

[0003]

However, in the conventional deburring apparatus of this type, since the burr is removed by friction with the buff, the rotation speed of the buff is adjusted according to the hardness of the burr. There is a disadvantage that the burr that has been removed must be scattered around and work is troublesome.

An object of the present invention is to eliminate such inconvenience.

[0005]

In order to achieve the above object, in the deburring device according to the present invention, a through hole is formed in the center of the board, and a blade portion is formed at the inner peripheral edge of the upper end of the through hole. A bar-shaped workpiece having a burr on the peripheral surface and having an outer diameter substantially equal to the inner diameter of the blade of the deburring tool, so that the rod-shaped workpiece is press-fitted from the upper end side of the through hole by appropriate means. It was done.

Further, in the deburring tool according to the present invention, a through hole is formed in the central portion of the board and a blade portion is provided on the inner peripheral edge of the upper end of the through hole.

Since the deburring apparatus according to the present invention is configured as described above, when a rod-shaped work is press-fitted into the through hole of the board, the burr protruding on the peripheral surface of the work is cut by the blade portion of the through hole. It is scraped off.

Since the deburring tool according to the present invention is constructed as described above, it is easy to use for the deburring device.

1 is a sectional view of a deburring apparatus according to the present invention, and FIG. 2 is a plan view of the deburring tool in FIG.

In FIG. 1, reference numeral 10 denotes a base of the deburring device D, which has a substantially cylindrical shape. The base 10 has a shaft hole 11 whose inner diameter is larger than the outer diameter of the workpiece W described later. 20
Is a support and is inserted into the shaft hole 11 so as to be able to move forward and backward. The function of the shaft hole 11 of the support tool 20 will be described later. Reference numeral 21 is a compression spring, which is arranged at the bottom of the shaft hole 11
It supports 20 elastically in the direction of advance and retreat.

In FIGS. 1 and 2, reference numeral 30 denotes a disc-shaped deburring tool, which is mounted on the top surface of the base 10 and has bolts 31, 31, ... The deburring tool 30 is composed of a disk body 32, and the axis thereof is aligned with the axis of the base 10. Further, 33 is a through hole, which is formed along the axis of the disk body 32. This through-hole 33 is the base 10
The shaft hole 11 is integrally connected. Reference numeral 34 denotes an annular blade stand, which is provided so as to protrude from the inner peripheral edge of the upper end of the through hole 33. Further, 341 is an annular blade portion, which is formed on the inner peripheral edge of the upper end of the blade base 34.

Next, in FIG. 1, W is a rod-shaped work, the outer diameter of which is substantially equal to the inner diameter of the blade portion 341 of the deburring tool 30. Further, B is a burr which is provided so as to project on the peripheral surface of the work W.

When removing the burr B of the work W by the deburring device D, first, the tip of the work W is inserted into the through hole 33 of the deburring tool 30. Then, the work W enters the through hole 33 and then the shaft hole 11 of the base 10, and the tip thereof is supported by the support tool 20. In this state, the work W is pushed out by operating the pressing tool 40 by the piston / cylinder mechanism 50, and the through hole 33
When it is press-fitted into the burr B of the work W,
It enters into the through hole 33 while being scraped by 1.
At this time, the compression spring 21 is compressed. After removing the burr B, if the operation of the pressing tool 40 by the piston / cylinder mechanism 50 is released, the work W is returned to the initial state by the elasticity of the compression spring 21. In this state, the work W is taken out from the through hole 33 to complete the deburring work.

[0014]

The deburring apparatus according to the present invention has a through hole formed at the center of the board and a blade portion at the inner peripheral edge of the upper end of the through hole. Since the rod-shaped work substantially equal to the inner diameter of the blade portion is press-fitted from the upper end side of the through-hole by appropriate means, when the rod-shaped work is press-fitted into the through-hole of the board, the burrs protruding on the peripheral surface of the work are Is to be scraped off by the blade portion of the through hole.

Therefore, if this deburring device is used,
Regardless of whether the burr is hard or soft, it is only necessary to press-fit the work into the through hole, which makes it easier to control the deburring work.Because the work extension operation is used, the removed burr is less likely to scatter. Is also easy to deburr.

Further, the deburring tool according to the present invention is easy to use in the deburring device because the through hole is formed at the center of the board and the blade portion is provided at the inner peripheral edge of the upper end of the through hole. Is.
