Abstract

Изобретение относитс к технологии машиностроени и может быть использовано при обработке в зких сталей и сплавов кругами на токопровод щей св зке. Целью изобретени вл етс повышение качества обработки. На корпусе шлифовального круга, выполненного из токонепровод щего материала, по спирали расположены два соосных, изолированных друг от друга рабочих элемента 2 и 3, имеющих на своей наружной поверхности абразивный слой и соединенных с двум полюсами источника посто нного тока. Концы элементов шарнирно закреплены на ползунах 4, установленных в пазах корпуса и фиксируемых клинь ми 5, 6. Направление движени ползунов определ етс из выражени , приведенного в формуле изобретени . 2 ил.The invention relates to mechanical engineering technology and can be used in the treatment of viscous steels and alloys in circles on a conductive bond. The aim of the invention is to improve the quality of processing. Two coaxial, isolated from each other working elements 2 and 3, having an abrasive layer on their outer surface and connected to two poles of a direct current source, are spirally located on the body of a grinding wheel made of a non-conducting material. The ends of the elements are hinged on the sliders 4 installed in the housing slots and fixed by wedges 5, 6. The direction of movement of the sliders is determined from the expression given in the claims. 2 Il.

Claims

Claim

A grinding wheel containing a screw elastic working element located on the casing with an abrasive layer on the surface is distinguished by the fact that, in order to improve the quality of processing, the grinding wheel is equipped with an additional working element mounted coaxially with the main one, and by the sliders, and on the ends of the body grooves are made in which the indicated sliders are pivotally connected to the working elements, IQ are placed. · while the working elements are made of their electrically conductive material and are insulated relative to each other,,

15 and the grooves relative to the line passing radially through the axis of the hinge are located at an angle p determined by the formula

20 β = arctan (--------------).

cos (arctg (-)) where η is the number of turns of elements;

S is the helix pitch of the elements; D is the diameter of the circle.
