Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grinding tool suitable for removing burr, etc. present at edges.

Removal of debris, etc. that exists at the edges is usually done by sanding,
It is carried out using plants such as Sasatsuba.

However, if the edge is not a simple shape but is formed, for example, in an arc shape, a high degree of skill is required to remove it.

This invention was made based on the above-mentioned circumstances, and is arranged in a row in the same direction on one plane, and the peripheral surface is used as a grinding surface, so that it can withstand the pressure contact with the workpiece in the above-mentioned situation. A plurality of straight wire spring bodies having rigidity and elasticity that adapts to the shape of the pressure-welded portion of the workpiece are provided, and one end of the wire spring bodies is integrally held by a fixing portion made of an elastic member. Even if the part to be processed has a complicated shape, it can be easily and accurately deburred into the desired shape.

Hereinafter, the present invention will be described based on examples with reference to the drawings.

As shown in FIGS. 1 and 2, a linear spring body 3 having a grinding surface formed by fixing an abrasive material 2 around an elongated and straight spring steel wire 1 having a circular cross section is identical on one plane. A plurality of pieces are arranged in rows in the direction.

The spring bodies 3 arranged in parallel are integrally fixed at one end to a fixing part 4 made of an elastic member.

In this illustrated example, the fixing part 4 is made of rubber or the like in the shape of a handle, in which a part of the spring body 3 is embedded and fixed.

The spring body 3 may be a strip-shaped spring body 3 in which the abrasive material 2 is fixed around an elongated spring steel plate 6 to form a grinding surface, as shown in FIG. 3a.

Further, as shown in FIG. 3b, the abrasive material 2 may be fixed only to the front and back opposing surfaces 8, 8 of the spring steel plate 6.

Furthermore, as shown in FIG. 3c, abrasive cloth paper 9 may be adhered to the front and back facing surfaces 8, 8 of the spring steel plate 6,
These make it easy to renew the grinding surface.

To perform deburring work, as shown in Figure 4b, the fixed part 4 is bent to grip the tool, and the linear spring bodies are arranged in a row in the same direction on one plane. The linear spring body 3 is oriented perpendicularly to an edge W having a complicated shape such as an arc, as shown in FIG. and in this pressed state, the grinding tool is slid in the longitudinal direction of the linear spring body 3.

When the grinding tool is formed as described above, (a) the tool is formed by arranging a plurality of linear spring bodies 3 in parallel, and has a grinding property, so that the workpiece is Even if the processed part has a complicated shape, the shape ←) Since the spring body 3 is strongly restrained by the fixed part 4 such as the part near the boxwood root, the fixed part 4
However, in the case of the conventional type in which the fixing part 4 is not made of an elastic body, the way it hits the edge W of the workpiece is different between the part near the root and the part far from the boxwood root, but if the fixing part 4 is made of an elastic body, the bending of the fixing part 4 will be different. The effect is that it is easier to perform chamfering work of a certain size because the chamfers are applied in the same way.

(c) Each of the linear spring bodies 3 arranged in parallel has strong rigidity that can withstand the pressure required for deburring, as shown by the material, so that it can be pressed against the workpiece by applying the force necessary for deburring. I can do it.

By combining the effects of (a), (b), and (c) above, the tool can be moved along the machining part of a workpiece with a complex shape so that each part of the spring body 3 in the longitudinal direction hits the same. Since it is possible to remove burrs by gripping and bringing them into close contact and applying the necessary amount of force for removing burrs, the required burr removal can be carried out quickly and easily.

In addition, since the plurality of linear spring bodies 3 are arranged in a row on the same plane, the tool can be adjusted to suit the shape of the workpiece, no matter what shape it is, such as a convex or concave surface. can be quickly and easily deburred by pressing the grinding tool into contact with the grinding tool; furthermore, the above-mentioned sliding back and forth can be performed extremely easily if the grinding tool is attached to the reciprocating portion 12 of the vibrating tool 11, as shown in FIG. be able to.

As described in detail above, the present invention is arranged in a row in the same direction on one plane, and has a peripheral surface as a grinding surface, and when the peripheral surface is pressed against a workpiece, it has the rigidity to withstand the pressure contact and the above-mentioned A plurality of straight wire spring bodies having elasticity that adapts to the shape of the pressed part of the workpiece are provided, and one end of the wire spring bodies is integrally held by a fixing part made of an elastic member, Since the linear spring body conforms well to a complicated shape and presses against it with sufficient strength, a workpiece having a complicated shape can be quickly and easily deburred.

Further, by selecting the parallel width t (FIG. 1) of the linear spring bodies, the length of the processed portion can be easily limited to an arbitrary dimension.

Additionally, the vibrating tool can be easily incorporated into an automated production system for edge machining.

It goes without saying that the present invention is not limited to the above-described embodiments, and can be modified in various ways without departing from the gist thereof.
