Thus, the deburring tool according to the present invention comprises a main body 1 having an installation groove 1a and a burr removing member entrance hole 1b, a leaf spring 2 installed in the installation groove 1a of the main body 1, , And a burr removing member (3) for holding the neutral position by the plate spring (2).

Herein, the installation groove 1a of the main body 1 is formed in the longitudinal direction of the main body 1 at one side of the main body 1, and the burr removing member entrance hole 1b of the main body 1, Is formed in the radial direction of the main body 1 from the lower side of the main body 1a.

The plate spring 2 is disposed in the installation groove 1a of the main body 1. The upper end of the plate spring 2 is fixed to the upper portion of the installation groove 1a of the main body 1, (3) is provided to maintain the neutral position of the burr removing member (3).

The burr removing member 3 is supported by the leaf spring 2 so that not only the burr removing member 3 enters and exits into the burr removing member access hole 1b of the main body 1, 8 of the hole 10a of the workpiece 10 as shown in FIG. 8 so as to protrude in the radial direction of the main body 1 through the burr removing member entrance hole 1b of the workpiece 10, And the burr 10b at the edge is removed.

The burr removing member 3 is fixed to the lower end of the leaf spring 2 with a screw 4 and maintains the neutral position by the elastic force of the leaf spring 2 as described above.

Of course, since the shape of the leading end portion of the burr removing member 3 is formed by machining a cutting portion for smoothly removing the burr as in the conventional art, a detailed description of the cutting portion will be omitted.

Although the deburring tool according to the present invention thus constructed is not shown, when the burr removing member 3 is inserted into the hole 10a of the workpiece 10, the burr removing member entrance hole 1b of the main body 1 is recessed The workpiece 10 can be smoothly inserted into the hole 10a of the workpiece 10. When the burr removing member 3 passes the hole 10a of the workpiece 10, The burr 10b formed at the edge of the hole 10a of the workpiece 10 can be removed by rotating according to the power rotation of the workpiece 1. [

However, when the burr removing member 3 is as shown in Fig. 2, when the burr removing member 3 moves into and out of the hole 10a of the workpiece 10, the body 1 Since the inclined surface must be formed on the upper and lower sides of the leading end portion of the burr removing member 3 protruding in the radial direction of the burr removing member 3, more machining accuracy is generated and the structure for cutting burrs becomes more complicated.
