Дополнительный упор 6 Снабжён рабочей поверхностью, контактирующей с торцом изделия в процессе притупления острой кромки.The device comprises a rolling mechanism made in the form of an ex3 929334 centric disk, an emphasis mounted on an axis 2 mounted on a mandrel 3 mounted with a possibility of rolling relative to axis 4 on the housing 5 in the form of a handle, on the end of which an additional emphasis 6 is installed, a cutting tool 7 mounted in the mandrel 3 and elastically pressed by the spring 8 to the sharp edge of the workpiece 9 · The screw adjusts the stiffness of the spring 8. Additional stop 6 Provided with a working surface in contact with the end face of the product during blunting I have a sharp edge.

Приспособление работает следующим образом.The device works as follows.

Оператор, удерживая приспособление рукой за ручку корпуса 5, подводит его к вращающемуся обрабатываемому изделию 9, например на токарном станке, до контакта упора 6 рабочей поверхностью с торцом обрабатываемого изделия 9» режущего инструмента 7 с вершиной острой кромки изделия и эксцентричного диска-упора механизма 1 качения с цилиндрической поверхностью изделия 9· Обрабатываемое изделие 9 передает вращение, например эксцентричному диску меха. низма 1 качения, за счет сил контактного трения между поверхностями изделия и эксцентричного диска-упора. Механизм 1 качения инструмента изменяет угловое положение оправки 3, обеспечивая изменение угла наклона режущей кромки инструмента 7 по отношению к образующим острой кромки.The operator, holding the device with his hand by the handle of the housing 5, brings it to the rotating workpiece 9, for example on a lathe, until the stop 6 contacts the working surface with the end face of the workpiece 9 ”of the cutting tool 7 with the apex of the sharp edge of the product and the eccentric disk-stop mechanism 1 rolling with a cylindrical surface of the product 9 · The workpiece 9 transmits rotation, for example to an eccentric fur disk. 1 rolling, due to the forces of contact friction between the surfaces of the product and the eccentric disc-stop. The mechanism 1 of the rolling tool changes the angular position of the mandrel 3, providing a change in the angle of inclination of the cutting edge of the tool 7 with respect to forming a sharp edge.

' Режущий инструмент 7, совершая осевое движение в оправке и качательное движение по радиусу совместно с оправкой 3 относительно оси 4, обеспечивает радиусное срезание острой кромки и снятие заусенцев. После 5 притупления одной острой кромки оператор переносит приспособление на другую острую кромку и т.д. Приспособление обеспечивает как радиусное притупление острых кромок на наружных и внутренних поверхностях изделий, так и повышение производительности и качества притупления кромок изделия.'' The cutting tool 7, making an axial movement in the mandrel and a swinging motion along the radius together with the mandrel 3 relative to the axis 4, provides a radial cutting of the sharp edge and deburring. After 5 blunting of one sharp edge, the operator transfers the device to another sharp edge, etc. The device provides both a radial blunting of sharp edges on the outer and inner surfaces of the products, and an increase in productivity and the quality of blunting the edges of the product.

Claims

The invention relates to machining, mainly hand tools for blunting sharp edges when machining products on lathes. According to the main auth. a device is known for blunting sharp edges containing a mandrel with a cutting tool and a tool swing mechanism made in the form of an eccentric disk disposed on an axis fixed to the mandrel, the cutting tool being mounted in a frame with a possibility of movement and elastically preloaded by a spring jf The disadvantage of the known device is The fact that it does not provide the possibility of combining the swing axis of the mandrel with the top of the sharp edge of the workpiece, when installed, which reduces its functional Opportunities The purpose of the invention is to expand the functionality of the device by allowing the alignment of the swing axis of the mandrel with the top of the sharp edge of the workpiece. This goal is achieved by the fact that in the device for blunting sharp edges, the housing carrying the spring-loaded mandrel is provided with an additional stop mounted on its end, the additional stop being made in the form of a shoulder disc and mounted on an axis fixed to the handle body or protrusion on the end of the case. FIG. 1 shows the device, a general view of FIG. 2 - view A (turned), in FIG. one; in fig. 3 stop, made in the form of a rectangular protrusion; in fig. - emphasis, made in the form of a disc with a collar. The fixture contains a rolling mechanism 1, made in the form of an eccentric disk, an emphasis mounted on an axis 2 mounted on a mandrel 3 mounted with a possibility of rolling relative to the axis A on the body 5 in the form of a handle, on the end of which an additional emphasis 6 is installed, the cutting tool 7 mounted in the mandrel 3 and resiliently pressed by the spring 8 to the sharp edge of the workpiece 9. The screw adjusts the stiffness of the spring 8. Additional stop 6 Equipped with a working surface in contact with the end of the product during blunting edge system. The device works as follows.
