Description

Изобретение относитс к изготовлению абразивного инструмента.The invention relates to the manufacture of an abrasive tool.

Цель изобретени - повышение размерной стойкости инструмента путем повышени плошади режуш.их участков.The purpose of the invention is to increase the dimensional stability of the tool by increasing the area of their sites.

На фиг. 1 изображен инструмент с четырьм планетарными кругами и одним шли- фавальным кругом, выполненным в виде двух концентричных дисков; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - то же,FIG. 1 shows a tool with four planetary circles and one grinding wheel made in the form of two concentric disks; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the same

мент контактирует с шлифуемой поверхностью один раз и определенным участком режуш,ей поверхности. При этом равномерность износа кругов 4 обеспечиваетс последовательной сменой точек контакта кругов 4 с обрабатываемой поверхностью. Последнее обеспечено тем, что отношение числа зубьев солнечной шестерни и каждой из шестерен 7 выбрано иррациональным. Вибрации, возникаюш.ие в системе при рашлифовальный круг представлен в виде 10 боте указанным кругом, снижены в сраводного диска; на фиг. 4 - сечение Б-Б на фиг. 3.The cop is in contact with the surface to be ground once and at a certain part of the cut, and the surface. In this case, the wear uniformity of the wheels 4 is ensured by successively changing the contact points of the wheels 4 with the surface to be treated. The latter is ensured by the fact that the ratio of the number of teeth of the sun gear and each of the gears 7 is chosen irrational. Vibrations that occur in the system when the grinding wheel is represented in the form of a bot with the indicated circle are reduced in a free disk; in fig. 4 is a section BB in FIG. 3

Инструмент состоит из шпиндел 1, на котором закреплены диски 2, несушие оправки 3 с шлифовальными кругами 4 и кругом 5. Круги 5 концентричны шпинделю 1, круги 4 концентричны оправкам 3. Круги 4 имеют планетарный привод вращени , выполненный в виде солнечного колеса 6, неподвижно закрепленного на корпусе шли15The tool consists of a spindle 1 on which the disks 2 are fixed, the bearing bars of the mandrel 3 with grinding wheels 4 and a circle 5. The circles 5 are concentric with the spindle 1, the circles 4 are concentric with the mandrels 3. The circles 4 have a planetary rotational drive, made in the form of a sun wheel 6, fixed mounted on the housing

Claims

Invention Formula

Abrasive tool, made in the form of a planetary grinding head, the spindle of which carries located

foveal grandmother. Around the sun, a circle of 20 and a kine. Mathematically associated with

6 gears 7 are driven around, each with a solar wheel mandrel, from which is mounted on the opposite.

relative to the circle 4 end of the mandrel 3.

on one end of each w wheel, and on the other - gear, characterized in that, for the purpose of spindle 1 with disks 2, circle 5 rotates to increase tool life, it is up to the same angular speed, moving and equipped with a rigidly fixed

mandrels 3 with gears 7. The latter, running in the sun wheel 6, report additional din 4.

The ratio of the number of teeth of the sun- cutting unit and (1) went (|) to planetary moving, and the elements are characterized by the fact that the wheel and the gears of the mandrel are equal to one cutting spindle for one revolution of the spindle.

In the process of grinding during rotation

The angular displacement of the spindle by the grinding wheel is a grinding wheel whose peripheral surface is flush with the peripheral sections of the wheels located on the mandrels.

The cop is in contact with the surface to be ground once and at a certain part of the cut, and the surface. In this case, the wear uniformity of the wheels 4 is ensured by successively changing the contact points of the wheels 4 with the surface to be treated. The latter is ensured by the fact that the ratio of the number of teeth of the sun gear and each of the gears 7 is chosen irrational. Vibrations that occur in the system during operation

with a tool with planetary circles. This provides a reduction in the roughness of processing, increasing the dimensional resistance of the tool.

Invention Formula

the ratio of the number of teeth of the sunwheel and the gears of the mandrel is equal to the spindle free wheel by the grinding wheel, the peripheral surface of which is located at the same level with the peripheral parts of the circles located on the mandrels.
