この考案はグラインダ、研磨機などの除塵装置
に関するもので、特に、研削作業によつて生じる
粉塵を回収し外部へ排除するための除塵装置に関
するものである。[Detailed description of the invention] [Industrial application field] This invention relates to a dust removal device for grinders, polishers, etc., and in particular, to a dust removal device for collecting dust generated by grinding work and discharging it to the outside. It is something.
一般に研削、研磨作業において生じる粉塵を回

In order to collect the dust that is generally generated during grinding and polishing work, the rear part of the grinding wheel, impeller, and other grinding wheels is covered with a dust removal cover, and the air inside the dust removal cover is discharged to the outside along with chips and dust using a dust removal fan. It is being done.

とが出来なくなる不具合を生じる。 With this kind of dust removal cover, the larger the circumferential angle that covers the grinding wheel, in other words, the less the degree of exposure of the grinding wheel, the higher the airflow velocity near the grinding wheel, and the more effective the dust removal effect. On the other hand, if the circumferential angle of the dust removal cover covering the grinding wheel is too large, the grinding wheel will be hidden by the dust removal cover, resulting in a problem that a large object to be ground cannot be polished.

Conventionally, in order to handle large objects to be ground, only the rear half of the grinding wheel was covered with a dust removal cover, and the front opening was made larger. This is covered by recruitment. However, this method was inefficient and unsatisfactory both economically and functionally.

The purpose of this invention is to solve the above-mentioned problems, to make it possible to process objects of various sizes, and to obtain a dust removal device that can efficiently remove dust using relatively small dust removal equipment. The dust removal cover 5 of the wheel 3 is supported by the base 6 and covers the rear half of the grinding wheel 3, with a fixed side half 7 having a substantially half-moon shape when viewed from the side, and a side surface similarly supported inside the fixed side half 7. It is composed of a movable half part 8 that is approximately half moon-shaped in appearance, and the movable half part 8 is connected to the fixed half part 7 by a support shaft 5a.
It is characterized in that a part of the dust removal cover 5 is swingably protruded from the opening of the fixed side half 7 to the front side, and the inner surface of the dust removal cover 5 is connected to the air exhaust port 7a.

The movable half 8 of the dust removal cover hangs due to its own weight, and part of it protrudes forward from the opening of the fixed half 7 so that it can swing freely, so that only the part covered by the movable half 8 is covered by the movable half 8. The circumferential angle covered by the grinding wheel is increased compared to the conventional one.
大型の被研削物Wを研磨するときには、被研削
物Wによつて可動側半部8を押し下げれば被研削
物Wの大きさに応じて所望の量だけ研削車外周の
露出部分が増大する。 When polishing a large object W to be ground, if the movable side half 8 is pushed down by the object W to be ground, the exposed portion of the outer periphery of the grinding wheel increases by a desired amount depending on the size of the object W to be ground. .
加工が終了して被研削物Wが無くなれば、可動
側半部8は開口部の小さい元の位置に復帰する。 When the machining is completed and the object to be ground W is removed, the movable half 8 returns to its original position with a small opening.

Hereinafter, this invention will be explained with reference to the illustrated embodiment. In the figure, 1 is a buffing machine with two units, and these are grinding wheels 3, 3 supported by a common drive shaft 2.
It is equipped with 4 is a drive shaft 2 via a belt 4a.
It is an electric motor that drives the A dust removal cover 5 covers the outer periphery of the grinding wheel 3, and is provided separately for each of the grinding wheels 3, 3.

になつている。 The dust removal cover 5 is provided to cover the rear half of the grinding wheel 3 and is supported by a base 6 independent of the grinding wheel 3. The dust removal cover 5 is fixed to the base 6 and has a box-shaped stationary half 7 with a half-moon-shaped side surface that covers the rear half of the grinding wheel 3, and is attached to the inner surface of the stationary half 7 by a support shaft 5a. It is composed of a similarly suspended movable side half 8 having a substantially half-moon shape. The movable side half 8 has side plates 8a, 8a on both sides and their outer peripheries as an outer plate 8b.
It has an arcuate outer surface that is inscribed in the inner surface of the stationary half 7. In this embodiment, a part of the latter half of the movable half 8 is removed, and a balance weight 8c is provided to replace the weight of that part. The balance weight 8c is slidably and fixedly locked to the column 8d in the radial direction, and by moving it, the amount of protrusion of the movable side half 8, in other words, the circumferential angle covering the grinding wheel 3 can be increased or decreased. It has become possible to do so.

度を高めることができる。 Reference numeral 7a denotes an air exhaust port that communicates with a dust exhaust fan (not shown), and communicates with the space 9 formed between the grinding wheel 3 and the dust removal cover 5. The upper opening 9a of the gap 9 is closed by a substantially U-shaped lid member 9b provided on the fixed half 7, and the lower opening 9c is closed with a soft material covering the inner surface of the opening edge of the movable half 8. It is covered with a protective member 10 made of fiber. Thus, opening 9
The speed of air flowing into the dust removal cover 5 through the dust removal cover 5 can be increased.

が、同図で示される小型の被研削物Wを研削する
には特に支障はない。 Next, the operation of the embodiment will be explained. Before starting the polishing work, as shown in FIG. 1, the movable side half 8 is at a position where the counterclockwise moment due to its own weight and the clockwise moment due to the balance weight are balanced, that is, the protective member 10 protrudes toward the front side of the grinding wheel 3 to a position where it becomes almost horizontal. In this state, it protrudes to the front side of the grinding wheel 3. In this state, the circumferential angle at which the grinding wheel 3 is exposed from the dust removal cover 5 is small, but this does not pose any particular problem in grinding the small-sized workpiece W shown in the figure.

易に推測されよう。 When the object W to be ground is relatively large, or when a bar-shaped object W to be ground is to be polished along the longitudinal direction, the object W to be ground is rotated with the movable half 8 as shown in FIG. When the protective member 10 provided on the edge is pressed downward or backward, the movable side half 8 resists the clockwise rotational moment given by the balance weight 8c and rotates counterclockwise depending on the magnitude of the rotational moment. The degree of exposure of the grinding wheel 3 is increased by rotating in the direction shown in FIG. When the work is completed and the object W to be ground is removed, it can be easily inferred from the above explanation that the movable side half 8 automatically returns to its original position.
この考案は以上のように、研削車3の外周の多
くの部分を除塵カバー5で覆い、研削車3の露出
量を設定の小さい値に自動復帰させるものである

きる。
As described above, this invention covers most of the outer circumference of the grinding wheel 3 with the dust removal cover 5 and automatically returns the amount of exposure of the grinding wheel 3 to the small value set, so that the exhaust air inlet is By increasing the speed of air flowing into the gap 9 between the narrowed grinding wheel 3 and the dust removal cover 5, dust including grinding debris can be efficiently sucked into the dust removal cover 5 and removed even by a relatively small fan. .
また、除塵カバー5を構成する可動側半部8は
揺動自在に吊り下げ、重力で安定な位置へ復帰さ
せるから、構造が簡単で作動が確実である。 In addition, the movable side half 8 constituting the dust removal cover 5 is swingably suspended and returned to a stable position by gravity, so the structure is simple and the operation is reliable.
更に、非作業時の研削車3の露出量が自動的に
減じるから研削車3への接触事故が減り安全性が
高まるなどの効果もある。 Furthermore, since the amount of exposure of the grinding wheel 3 during non-operation is automatically reduced, there are also effects such as fewer accidents involving contact with the grinding wheel 3 and increased safety.
