(54) УСТРОЙСТВО ДЛЯ ПРАВКИ ШЛИФОВАЛЬНОГО КРУГА(54) DEVICE FOR THE EDITION OF THE GRINDING ROUND

1 ,one ,

Изобретение относитс к машиностроению , а именно к правке шлифовальных кругов алмазными карандашами, предназначенной дл восстановлени режущей способности шлифовальных кругов и придани им заданной геометрической формы.5The invention relates to mechanical engineering, in particular to the straightening of grinding wheels with diamond pencils, designed to restore the cutting ability of grinding wheels and give them a given geometric shape.

Известно устройство дл правки шлифовального круга,- содержаш,ее закрепленный неподвижно на столе станка корпус , в котором с помош,ью упругого элемен та установлен алмазный карандаш. В извест ном устройстве пружина или резина подбираютс таким образом, чтобы гасить колебани прав щего инструмента, возникающие от удара абразивных зерен, и огибать их при правке, а св зку и шлам, как более податливые, срезать 1.jsA device is known for straightening a grinding wheel, which contains a case fixedly mounted on a machine table, in which, with the help of an elastic element, a diamond pencil is mounted. In a known device, the spring or rubber is selected in such a way as to dampen the oscillations of the right tool, arising from the impact of the abrasive grains, and to bend around them during straightening, and cuts and sludge, as more pliable, cut 1.js

После правки шлифовального круга с применением известного устройства его по- s верхность состоит из притупившихс в процессе предыдушего шлифовани абразивных зерен. Шлифование таким кругом вызывает ожог обрабатываемой поверхности. Так как при такой правке не происходит разрушение абразивных зерен, то и не исправл етс геометрическа погрешность формы круга.After the grinding wheel is edited using a known device, its surface consists of abrasive grains which have been blunted during the previous grinding process. Grinding in such a circle causes burns to the treated surface. Since this straightening does not destroy the abrasive grains, the geometrical error of the circle shape is not corrected.

Целью изобретени вл етс повышение качества правки.The aim of the invention is to improve the quality of edits.

Поставленна цель достигаетс тем, что в устройстве дл правки шлифовального круга, содержащем закрепленный неподвижно на столе станка корпус, в котором с помощью упругого элемента установлен алмазный карандаш, упругий элемент выполнен в виде мембраны, в отверстии которой жестко закреплен алмазный Карандаш , а ее перифери защемлена в корпусе устройства.The goal is achieved by the fact that in the device for dressing a grinding wheel containing a case fixedly mounted on a machine table, in which a diamond pencil is installed with the help of an elastic element, the elastic element is made in the form of a membrane in which the diamond pencil is rigidly fixed and its periphery is clamped in the device case.

На чертеже представлена часть устройства дл правки шлифовального круга.The drawing shows a part of the device for dressing the grinding wheel.

Алмазный карандаш 1 с помощью втулки 2 жестко закреплен в отверстии мембраны 3, котора по периферии защемлена в державке 4 при помощи накидной гайки 5, Пиноль 6 установлена в корпусе (не показан ) прав щего устройства. Державка 4 жестко закреплена в отверстии пиноли 6 винтом 7.The diamond pencil 1 is rigidly fixed with the sleeve 2 in the opening of the membrane 3, which is clamped in the periphery of the holder 4 by means of a cap nut 5, Pinol 6 is installed in the housing (not shown) of the right side device. The holder 4 is rigidly fixed in the hole of the quill 6 screw 7.

Claims

When the abrasive grains interact with the working surface of the diamond pencil 1, the latter receives oscillations in the radial direction of the grinding wheel with a frequency and amplitude corresponding to the characteristic of the elastic element, and the screw groove on the surface of the circle is wavy. At the same time, a part of the abrasive grains protruding above the bond, the vertices of which are located in the trough of the wave, move during the grinding process over the treated surface without touching it, the other part of the grains whose vertices are located on the crest of the wave, more effectively cuts into this surface . Due to the fact that the tops of the grains located in the hollow of the helical grooves, due to its waviness, are able to cut into the surface being processed, the effect of the helical grooves on the surface roughness decreases, and as a result of more periodic contact of the grains with the surface of the part, the risk of its burning decreases. grinding power. The proposed device is characterized with a higher compared with the known efficiency. After the grinding wheel is edited by the proposed device, the grinding power is reduced by 40% and the roughness of the grinding surface is doubled compared to the surface ground by a circle guided by a known device. The invention includes a grinding wheel fixedly mounted on a machine table, a housing in which a diamond stick is installed with the help of an elastic element, characterized in that, in order to improve the quality of editing, the elastic element is made in the form of a membrane in which a diamond is rigidly fixed pencil, and its periphery is pinched in the device.
