Изобретение относитс к механической обработке материалов, а именно к устройствам дл закреплени деталей, например при хонинговании.The invention relates to the machining of materials, namely, devices for securing parts, for example, when honing.

Известно устройство дл закреплени деталей , содержащее корпус, втулку и опору, выполненную в виде размещенного между корпусом и втулкой в ее верхнем сечении кольца с двум парами полуосей, одними концами жестко закрепленных в корпусе или втулке, а другими размещенных в ложементах кольца 1.A device for securing parts is known, comprising a housing, a sleeve and a support made in the form of a ring with two pairs of semi-axes placed between the housing and the sleeve in its upper section, one end rigidly fixed in the housing or sleeve, and the other placed in the cradle of the ring 1.

Недостатком указанного устройства вл етс невысока точность обработки деталей больщой длины, обусловленна воздействием на них изгибающего момента, возникающего при несоосности обрабатываемой поверхности детали и направлени действи осевых сил резани .The disadvantage of this device is the low accuracy of machining large lengths, due to the impact on them of the bending moment arising from the misalignment of the workpiece surface and the direction of the action of axial cutting forces.

Цель изобретени - повышение точности обработки деталей больщой длины за счет обеспечени соосности обрабатываемой поверхности детали и направлени действи осевых сил резани .The purpose of the invention is to improve the accuracy of machining of large lengths by ensuring the alignment of the machined surface of the part and the direction of the action of axial cutting forces.

Указанна цель достигаетс тем, что устройство снабжено дополнительной опорой,This goal is achieved in that the device is provided with an additional support,

размещенной в нижнем сечении втулки, при этом ложементы обоих колец выполнены в виде V-образных, направленных навстречу друг другу пазов, причем рассто ние между их опорными поверхност ми меньще рассто 5 НИН между опорными поверхност ми полуосей опор.placed in the lower section of the sleeve, with the lodgements of both rings made in the form of V-shaped, directed toward each other grooves, and the distance between their supporting surfaces is less than 5 NIN between the supporting surfaces of the axes of the supports.

На фиг. I изображено устройство, продольный разрез; на фиг. 2 - вид А на фиг. 1.FIG. I shows the device, a longitudinal section; in fig. 2 is a view A of FIG. one.

,Q Устройство содержит корпус 1, втулку 2 и две опоры, размещенные в верхнем и нижнем сечени х втулки 2 и выполненные в виде размещенных между корпусом 1 и втулкой 2 колец 3 и 4 и двух пар полуосей 5-8. Причем полуоси 5 и 7 жестко закреплены кон15 ца-ми во втулке 2, а полуоси 6 и 8 - в корпусе 1. Другими концами полуоси 5-8 размещены в ложементах 9 и 10 колец 3 и 4. Ложементы 9 и 10 выполнены в виде V-образных , направленных навстречу друг другу, Q The device includes a housing 1, a sleeve 2 and two supports placed in the upper and lower sections of the sleeve 2 and made in the form placed between the housing 1 and the sleeve 2 rings 3 and 4 and two pairs of half-axes 5-8. Moreover, the half axles 5 and 7 are rigidly fixed with ends 15 in hub 2, and half axes 6 and 8 - in housing 1. The other ends of half axles 5–8 are located in lodgments 9 and 10 of rings 3 and 4. The lodgements 9 and 10 are made as V -shaped towards each other

20 пазов, причем рассто ни между их опорными поверхност ми меньще рассто ни между опорными поверхност ми полуосей опор 5-8 на величину А .There are 20 slots, and the distances between their supporting surfaces are less than the distances between the supporting surfaces of the semiaxes of the supports 5-8 by an amount A.

Устройство работает следующим образом .The device works as follows.

Claims

Claim

A device for fixing parts, comprising a housing, a sleeve and a support, made in the form of a ring placed between the housing and the sleeve in its upper section with two pairs of half shafts, one ends of which are rigidly fixed in the housing or sleeve, and the other placed in the lodgements of the ring, characterized in that , in order to increase the accuracy of processing, the device is equipped with an additional support located in the lower section of the sleeve, while the lodgements of both rings are made in the form of V-shaped grooves directed towards each other, and the distance between their supporting surfaces are less than the distance between the supporting surfaces of the axles of the supports.

the movement of the honing head and the relative position of the workpiece and the honing head, the axial cutting force is directed from the support ring, which eliminates the occurrence of bending moment and;
