Field of the Invention The present invention relates to a grinding tool for an H-section steel, and more particularly to a grinding tool for an H-section steel in order to remove burrs and black scale on the H-section steel by drilling. The present invention relates to a grinding tool suitable for grinding each part.

The shaped steel is cut to the required dimensions and perforated in a predetermined pattern at both ends or at appropriate positions in the middle,
A seam plate having the same pattern of perforations is brought into contact therewith to adjust the positions of the holes, and the two are tightened with high-strength bolts, so that they can be assembled at a construction site or the like.

In addition, in order to keep the coefficient of friction with the seam plate constant, the periphery of the perforated portion must be removed. It is necessary to remove black scale (rolled black scale or oxide film) by grinding.

に、確実に孔周辺の鋼材表面の研削が可能となる。Conventionally, such a grinding operation has been performed manually by using a hand-held grinding tool called a disk sander. However, the safety and workability of this type of surface grinding operation around a hole is high. For the purpose of improving, a cup-shaped member fixed to the rotating shaft of the electric motor is provided with a guide pin coaxially with the rotating shaft, and two inner and outer rings are attached concentrically around the guide pin, A plurality of segment-shaped grinding wheels are fixed to each ring,
A hand-held tool dedicated to surface grinding around a hole in a steel material has been proposed in which each of these rings can be independently displaced in the rotation axis direction via a spring (Japanese Patent Publication No. 7-10502).
issue). According to this proposed tool, the electric motor is rotated while the guide pin is inserted into a hole formed in a steel material such as an H-section steel,
The guide pin is moved circularly along the inner peripheral surface of the hole so that the whetstone of each ring is brought into contact with the surface of the steel material. Even if there is a certain amount of undulations caused by the above, the inner and outer rings follow and appropriately displace, so that the steel material surface around the hole can be surely ground.

Feeds the H-beam so that it penetrates the inside of the U-shaped frame, and moves each grinding head along its surface while automatically positioning each grinding head on both flanges of the H-beam and each perforated portion of the web. By doing so, an H-section steel surface grinding apparatus capable of efficiently grinding the surface of the H-section steel around the drilled portion has been proposed (Japanese Patent Application Laid-Open No. 8-1083).

ラブルが生じる。A hand-held tool dedicated to surface grinding around a hole based on the above proposal is
By removing the central guide pin, it can be applied as a grinding tool to be mounted on the grinding head of the above-described fully automatic H-section steel surface grinding device. In order to improve the followability, it is preferable to make the diameter of the inner and outer rings as small as possible. However, when the diameter of the ring is reduced to a certain degree or more in proportion to the diameter of the hole, when the whetstone is moved while being pressed against the surface to be ground by a fully automatic type surface grinding device, each ring becomes independent. Since the outer ring is large enough to be displaceable in the axial direction of the rotating shaft, there is no problem because the outer ring is large enough, but the segment-shaped grindstone fixed to the inner ring is deeply penetrated into the periphery of the hole, and the grindstone is Troubles such as chipping or scraping the peripheral portion of the hole into a sliver may occur.

In this case, most of the grindstones in the inner ring are chipped, and the peripheral edge of the hole is cut into a sliver-like shape by the grindstones, thereby causing processing defects.

An object of the present invention is to provide a grinding tool for an H-section steel which can be used in a fully automatic type surface grinding apparatus and can perform stable surface grinding without being stuck in the periphery of the H-shaped steel.

れるよう構成されていることによって特徴づけられる。In order to achieve the above object, a grinding tool for an H-section steel according to the present invention comprises a holding member fixed to a shaft end of a rotating shaft and a concentric center with respect to the holding member. An outer ring and an inner ring to which rotation of the rotation shaft is transmitted via the holding member, and a plurality of segment-shaped grinding wheels are concentrically fixed to the outer and inner rings, respectively. The outer and inner rings are each displaceable in a direction to approach and separate from the holding member, and are urged by an elastic body in a direction to separate from the holding member, and the inner ring is , Can be independently displaced in the direction approaching the holding member,
The separation direction is characterized by being configured such that the amount of separation from the holding member is regulated according to the position of the outer ring by contact with the outer ring.

り込もうとするのを防止することができる。According to the H-shaped steel grinding tool of the present invention, similarly to a handy type tool dedicated to surface grinding around a hole based on the above-mentioned proposal, even if the surface to be ground has a certain degree of undulation, it appropriately follows. As a result, the inner and outer rings are displaced toward and away from the holding member, and the surfaces thereof can be ground substantially uniformly. In this following operation, the inner ring is independently displaced with respect to the outer ring in the direction approaching the holding member, but is in contact with the outer ring in the direction away from the holding member and the amount of separation is reduced. Be regulated. Therefore, even if the diameter of the inner ring is reduced in proportion to the diameter of the hole drilled in the surface to be ground, when the inner ring arrives at the position of the hole, the inner ring is restricted by the outer ring. Because it does not protrude further from the flange, that is, it does not protrude to the grinding surface side, it prevents the segment-shaped grinding wheel fixed to the inner ring from trying to cut the periphery of the hole deeply can do.

とを特徴とするＨ形鋼用研削工具。1. A tool for grinding the surface of an H-beam, comprising: a holding member fixed to a shaft end of a rotating shaft; and a supporting member concentrically supported by the holding member. While the outer and inner rings to which the rotation of the rotation shaft is transmitted via, the outer and inner rings are respectively fixed with a plurality of segmented grinding wheels concentrically,
The outer and inner rings are each displaceable in a direction to approach and separate from the holding member, and are urged by an elastic body in a direction to separate from the holding member. In the direction approaching the holding member, it is independently displaceable, and in the direction away from the holding member, the amount of separation from the holding member is regulated according to the position of the outer ring by contact with the outer ring. Grinding tool for H-section steel, characterized in that it is made.
