本考案はほこりを全て砥石の中に吸込み、排出
口より排出する構造のベンチグラインダー用ダイ
ヤモンド砥石に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a diamond grinding wheel for a bench grinder that has a structure in which all dust is sucked into the grinding wheel and discharged from an outlet.
従来ベンチグラインダー用の砥石は単に回転軸
により回転する回転体周面に被研削材を押付けて
研削するため、ほこりが辺りに飛散し、作業員の
健康を害する。
Conventional grindstones for bench grinders grind by simply pressing the material to be ground against the circumference of a rotating body rotated by a rotating shaft, which causes dust to fly around and harm the health of workers.
本考案の課題は、研削時に生じるほこりを全て
吸収し、飛散による弊害を除去することができる
ベンチグラインダー用ダイヤモンド砥石を提供す
ることにある。
An object of the present invention is to provide a diamond whetstone for a bench grinder that can absorb all the dust generated during grinding and eliminate the harmful effects of scattering.
本考案の手段は次のとおりである。 The means of the present invention are as follows.
中心に回転軸孔を有する短筒体の上下に円形上
面板と円形下面板を取付けて構成した回転体の前
記上、下面板間の周縁に、小孔を多数穿ち、小孔
を除く表面にダイヤモンド又はCBNの微粒子を

気孔部材を設け、下面板に吸引翼を有する吸気孔
を、上面板にフイルターを張設した排気孔を設け
たベンチグラインダー用ダイヤモンド砥石。 A rotating body is constructed by attaching a circular upper plate and a circular lower plate to the upper and lower sides of a short cylindrical body having a rotating shaft hole in the center, and a large number of small holes are bored on the periphery between the upper and lower plates, and the surface excluding the small holes is A metal annular grindstone plate electrodeposited with fine particles of diamond or CBN is attached, an annular vent member with a conical cross section with a narrow outlet is provided inside the annular grindstone plate, and an intake hole with suction blades on the bottom plate. A diamond whetstone for bench grinders with an exhaust hole with a filter on the top plate.
被研削物を砥石板２の表面に当てて研削する
と、屑やほこりは小孔から中空回転体内に入る。
その際中空回転体は高速で回転しているので、外
気は翼から吸込み排気孔から出る。その際排気孔

外部には清浄な空気が流れる。
When the object to be ground is ground against the surface of the grindstone plate 2, scraps and dust enter the hollow rotating body through the small holes.
At this time, since the hollow rotating body is rotating at high speed, outside air is taken in through the blades and exited through the exhaust holes. At that time, a filter is placed on the exhaust hole to attract dust and allow clean air to flow outside.

In the figure, reference numeral 1 denotes a hollow rotating body, which is equipped with a circular upper plate 6, a lower plate of the same shape, and a short cylindrical body 22 in the center that fixes both plates 6 and 6', and is positioned in equilibrium by the short cylindrical body 22. A metal annular grindstone plate 2 is removably installed in the space between the peripheries of the upper and lower plates 6 and 6', and
The hole in the short cylindrical body 22 is used as a rotation shaft insertion hole through the lower plates 6, 6', and the annular grindstone plate 2 has a large number of small holes 13.
diamond particles 14 are fixed on the surface except for the small holes 13 by electrodeposition. Further, an annular ventilation hole member 5 having a conical cross section is provided inside the annular grindstone plate 2, an intake hole 8 with a raised suction blade 7 is formed in the lower plate 6', and the upper plate 6 has a suction blade 7. , a frame plate 9 having an exhaust hole 11 with a filter sponge 10 stretched thereon is fixed.
本考案によれば、研削時に生じるほこりや研削
屑はフイルターに吸着させ外部に飛散することが
なく、衛生的に作業できる。それに別の集塵装置
を必要としない。
According to the present invention, dust and grinding debris generated during grinding are absorbed by the filter and are not scattered outside, allowing for sanitary work. It does not require a separate dust collector.
