Description

산업용 탁상형 드릴각도 연마기계{BENCH TYPE DRILL'S ANGLE GRINDER FOR GENERAL}Industrial Table Type Drill Angle Grinding Machine {BENCH TYPE DRILL'S ANGLE GRINDER FOR GENERAL}

본 발명은 일반적으로 제조기계공장이나 작업현장에서 사용되는 드릴공구의 포인트 각도연마를 위한 기계장치로서 드릴공구의 특성상 포인트각도의 크기 및 중심센터에 대한 드릴리브의 대칭성이 중요함에도 불구하고 지금까지는 대다수 작업자들이 합리적인 가격에 구입할 수 있는 기계장치가 없으므로, 또는 있다고 하더라도 800만원 이상의 고가의 기계를 구입할 수 없으므로 작업자가 임의로 시각적으로 판단하여 적당히 비대칭형으로 불균일한 각도로 드릴을 연마하여 사용하여 왔다.The present invention is a machine for point angle polishing of a drill tool generally used in a manufacturing machine shop or a work site. Since workers do not have a machine that can be purchased at a reasonable price, or even if you can not buy expensive machines of more than 8 million won, the worker has been used to polish the drill at a reasonable asymmetrical and non-uniform angle by visually discretion.

이로 인하여 피가공품의 구멍의 크기 , 형상 또는 위치에서 품질이 균일하지 못 하였으며, 결과적으로 제품불량의 원인과 경제적 손실을 초래함이 많았다.As a result, the quality was not uniform in the size, shape, or location of the hole in the workpiece. As a result, there were many causes of product defects and economic loss.

본 발명에서는 이러한 현실적인 문제점들을 해소하고자 하여 발명하게 되었으며, 소비자가격기준하여 20만원미만의 경제적이면서 다양한 욕구를 충족할 수 있는 현장성 있는 기계장치가 될 수 있도록 발명한다.The present invention has been invented in order to solve these realistic problems, and invented to be a field machine that can meet the economic and various needs of less than 200,000 won based on the consumer price.

대표도는 탁상형 드릴각도 연마기계의 전체예상도면이며, 도 1 은 작업상황의 단면도 (측면도)를 표시한다.A representative view is an overall expected view of a table-type drill angle grinding machine, and FIG. 1 shows a sectional view (side view) of a working situation.

도 2 는 작업할 드릴의 작업관련명칭을 표시하고 있으며, 대표도 및 도 1,2를 참조하여 본 발명기계의 사용을 간단히 설명하면 아래의 내용과 같다.Figure 2 shows the work-related name of the drill to be worked, briefly describe the use of the machine of the present invention with reference to Figures 1 and 2, as follows.

가, 작업자가 먼저 연마하고자 하는 드릴의 포인트각도(POINT ANGLE)를 결정한 후 각도조정눈금에서 적합한 크기로 선택하여 조정한 후 위치를 고정한다.A. First, determine the point angle of the drill to be polished by the operator, select the appropriate size from the angle adjustment scale and adjust the position.

나, 드릴위치에 작업하고자 하는 드릴(DRILL)을 끼우고 난 뒤 리브안착면에 적합한 위치에 드릴POINT가 위치할 수 있도록 드릴길이위치를 조정한 후 고정한다.B. After inserting the drill (DRILL) to be drilled at the drill position, adjust the drill length position so that the drill point is located at the position suitable for the rib seating surface and fix it.

다, 절입량 조정나사로서 연마석에 드릴포인트가 절입량만큼 닿도록 조절한 후 드릴고정구를 사용하여 드릴을 고정한다.C. Adjust the drill point so that the drill point touches the polished stone as the depth of cut, and fix the drill by using the drill fixture.

라, 드릴이 장착된 상부본체를 작업자가 적당한 위치에서 손으로 잡고서 회전중심을 기준하여 드릴포인트 및 드릴리브면이 연마석에 닿아서 연삭(GRINDING)될 수 있도록 연마한다.D) The operator holds the upper body equipped with the drill by hand at an appropriate position and polishes it so that the drill point and the drill rib surface can be ground by contacting the abrasive stone with respect to the center of rotation.

마, 이 때에 연삭량이 너무 과다하면 드릴포인트와 리브면이 타서 소실될 수 있으므로 주의하고, 필요에 따라 절입량 조정나사를 다시 조정한다.E. At this time, if the amount of grinding is too large, the drill point and the rib surface may burn out and be lost, and adjust the infeed amount adjusting screw again as necessary.

바, 작업이 완료되면 드릴이 장착된 상부본체를 회전중심을 기준하여 약 90도 회전하여 연마석과 멀리 위치해 두고서 드릴고정구를 풀고서 작업완료된 드릴을 빼낸다.Bar, When the work is completed, rotate the upper body equipped with the drill about 90 degrees from the center of rotation, away from the abrasive stone, loosen the drill fixture, and remove the completed drill.

본 발명의 구성은 대표도, 도 1에서 보는 바와 같이 기계의 몸체위에 연삭숫돌과 이를 회전하는 동력모터(220V*단상가)가 있으며, 드릴을 장착하여 회전하는 상부본체와 하부의 가이드등으로 구성된다.The configuration of the present invention, as shown in Figure 1, there is a grinding wheel on the body of the machine and a power motor (220V * single phase) that rotates it, and consists of the upper body and the lower guide and the like to rotate the drill mounted. .

동력전기는 어디에서든지 손쉽게 이용할 수 있는 220V 단상으로 하는 것을 원칙하고 소비자의 다양한 선택이 가능하도록 110V,220V,380V,440V도 할 수 있겠다.The principle of power electricity is 220V single phase which can be easily used anywhere, and 110V, 220V, 380V, and 440V can be made to allow various choices of consumers.

연마석의 무디어진 날을 고르게 깨끗하게 세위주는 드레싱(DRESSING)작업은 적당히 수동으로 할 수 있지만 소비자의 다양한 충족을 위해서 선택사양으로 드레싱장치를 연마석보호용 커버(COVER)에 별도로 부착할 수 있도록 한다.Even though the dressing work can be done by hand, it is possible to attach the dressing device separately to the cover for the abrasive stone protection.

본 발명은 드릴공구를 사용하는 모든 산업현장에서 보편적으로 사용이 가능할 수 있도록 설계제작함으로써 경제적으로 큰 부담없이 구입하여 손쉽게 사용할 수 있도록 고안하였다.The present invention is designed so that it can be easily used by purchasing economically by designing and manufacturing so that it can be universally used in all industrial sites using drill tools.

본 발명으로 인하여 아래와 같이 많은 경제적 생산적 효과를 볼 수 있겠다.Due to the present invention can be seen a number of economic and productive effects as follows.
