Abstract

PURPOSE: A wheel cover for a grinder is provided to remove inconvenience in work and to collect dust from grinding work easily by turning over a wheel cover through a corrugated portion formed at a cover fixing unit of the wheel cover. CONSTITUTION: A wheel cover(100) is made by transparent material, and a cover fixing unit(110) is formed on the wheel cover integrally with a corrugated portion(112) having a connecting plate and a screw hole(113). The wheel cover is assembled to the cover fixing unit by a screw, and the cover fixing unit is coupled with the wheel cover by another screw(70). Thereby, the wheel cover is assembled to a bearing housing. If the wheel cover is contacted earlier than a grinding disk, the wheel cover is turned over up by the corrugated portion. Therefore, a flat grinding surface is grinded smoothly. In addition, dust from grinding work is not dispersed to prevent workers from getting sick by sucking the dust.

그라인더용 휠커버{A wheel cover for grinder}Wheel cover for grinders {A wheel cover for grinder}

본 발명은 그라인더용 휠커버에 관한 것으로, 특히 집진이 용이하고, 먼지의 비산을 방지하기 그라인더용 휠커버에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel cover for a grinder, and more particularly, to a wheel cover for a grinder to easily collect dust and to prevent dust from scattering.

종래의 그라인더는 모터에 의해 회전하는 연마디스크에 의해 물체의 표면을 다듬거나 갈아내는 작업을 하는 도구로, 매우 빠른 속도로 회전하면서 물체를 연마하게 되므로 연마작업 중에는 많은 분진이 발생하는 반면, 도 1에 도시한 바와 같이 휠커버(50)가 커버고정구(60)에 의해 연마디스크의 후방만 커버할 수 있도록 형성되므로 커버하지 못하는 전방으로 연마분진이 연마디스크의 원심력에 의해 멀리까지 비산되므로 작업환경이 좋지 못하게 되고, 이로 인해 심각한 민원이 야기되고 있는 실정이다.Conventional grinders are tools that polish or grind the surface of an object by means of an abrasive disk that is rotated by a motor. The grinder grinds the object while rotating at a very high speed. As shown in FIG. 5, since the wheel cover 50 is formed to cover only the rear of the polishing disk by the cover fixing tool 60, the polishing dust is scattered to the far side by the centrifugal force of the polishing disk. This is causing serious complaints.

그렇다고 연마디스크의 전방부까지 휠커버로 차단하는 것은 물체의 작업위치를 확인할 수 없는 것이며, 설사 물체를 볼 수 있도록 투명하게 휠커버를 형성하였다 하더라도 휠커버가 젖혀지지 않으면 연마작업이 매우 곤란한 폐단을 갖는 것이다.However, blocking the front cover of the abrasive disc with the wheel cover cannot confirm the working position of the object, and even if the wheel cover is transparently formed so that the object can be seen, the polishing work is very difficult if the wheel cover is not flipped.

따라서 본 발명은 투명한 휠커버에 의해 연마디스크의 전방도 커버할 수 있도록 하되, 상기 휠커버에 결합되는 커버고정구에 주름부를 형성하므로 써 연마작업시 전방에 형성된 휠커버가 젖혀질 수 있도록 함으로써 작업에 큰 불편함이 없으면서도 연마분진의 집진은 용이한 그라인더용 휠커버를 제공하기 위한 것이다.Therefore, the present invention is to cover the front of the polishing disk by the transparent wheel cover, but by forming a crease in the cover fixture coupled to the wheel cover so that the wheel cover formed on the front during the polishing operation is inconvenient for work Without this, dust collection is to provide an easy grinder wheel cover.

본 발명을 첨부한 도면에 의해 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

베어링하우징(30)에 휠커버(50)와 나사(70)에 의해 결합되도록 하는 그라인더용 전방 휠커버에 있어서 상기 휠커버(100)는 투명의 재질로 제조되어지며, 상기 휠커버(100)의 상부에는 결합판(111)과 나사공(113)을 구비하는 주름부(112)가 일체로 형성된 커버고정구(110)로 구성된 것이다.In the front wheel cover for the grinder to be coupled to the bearing housing 30 by the wheel cover 50 and the screw 70, the wheel cover 100 is made of a transparent material, the coupling plate on the top of the wheel cover 100 Pleated portion 112 having a 111 and a screw hole 113 is composed of a cover fixture 110 formed integrally.

따라서 상기 휠커버(100)는 나사(114)에 의해 커버고정구(110)에 결합되고, 상기 커버고정구(110)은 다시 나사(70)에 의해 휠커버(50)와 체결되어 베어링하우징(30)에 결합되어지는 것이다.Therefore, the wheel cover 100 is coupled to the cover fixture 110 by a screw 114, the cover fixture 110 is again coupled to the wheel cover 50 by a screw 70 is coupled to the bearing housing 30 It is done.

따라서 본 발명은 도 4에 도시한 바와 같이 연마디스크(40)보다 휠커버(100)가 먼저 닿는 경우에는 주름부(112)에 의해 휠커버(100)가 위로 젖혀지므로 편평한 연마면을 연마함에 있어서도 그다지 큰 문제가 되지 않는다.Therefore, in the present invention, as shown in FIG. 4, when the wheel cover 100 comes in contact with the polishing disc 40, the wheel cover 100 is flipped upward by the pleats 112, so that even when polishing a flat polishing surface, the present invention is very large. It doesn't matter.

이처럼 본 발명은 투명한 휠커버에 의해 연마디스크의 전방도 커버할 수 있도록 하되, 상기 휠커버에 결합되는 커버고정구에 주름부를 형성하므로 써 휠커버가 젖혀질 수 있게 하여 작업에 큰 불편함이 없으면서도 연마분진의 비산을 방지하고, 이로 인해 작업자들의 분진흡입으로 인한 직업병 발생의 우려를 줄일 수 있으며, 또 그라인더의 케이스에 집진수단을 형성하는 경우 공기의 흡입을 용이하도록 도와줄 수도 있는 효과를 갖는 것이다.As described above, the present invention can cover the front of the abrasive disc by the transparent wheel cover, but by forming a crease in the cover fixture coupled to the wheel cover so that the wheel cover can be flipped so that there is no great inconvenience in the operation of the abrasive dust. Preventing scattering, thereby reducing the risk of occupational diseases caused by the dust inhalation of workers, and also has an effect that may help to facilitate the intake of air when dust collector is formed in the case of the grinder.
