Description

Изобретение относитс к станкостроению , а именно к станочным тисKciM металлорежущих станков.The invention relates to a machine tool industry, in particular to machine tools for machine tools.

Известные одноместные самоцентрирующие тиски содержат корпус с направл ющими и привод с губками, установленными на направл ющих 1.The known single-center self-centering vice contains a body with guides and a drive with jaws mounted on the guides 1.

Недостатком указанных тисков вл етс то, что дл самоцентрировани двух деталей по двум заданным ос м примен етс пара одноместных самоцентрирующих тисков, что. снижает производительность станков. Кроме того, установка двух одноместных самоцентрирующих тисков на одной рабочей позиции в преобладающем большинстве случаев невозможна из-за невозможности вписатьс в размеры шпиндельной коробки .The disadvantage of these clutches is that for self-centering two parts on two given axes, a pair of single-place self-centering clutches is used, which. reduces machine productivity. In addition, the installation of two single self-aligning vise on one working position in the overwhelming majority of cases is impossible due to the inability to fit into the dimensions of the spindle box.

Наиболее близкими к изобретению вл ютс двухместные станочные-тиски , содержащие корпус, две пары.подвижных губок и привод С 2.Closest to the invention are double machine-clutches comprising a body, two pairs of movable jaws and a C 2 drive.

Недостаток указанных тисков заключаетс в том, что они используютс дл зажима двух деталей, но не .обеспечивают их самоцентрировани .The disadvantage of these vices is that they are used to clamp the two parts, but they do not provide their self-centering.

Цель изобретени - обеспечение самоцентрировани двух деталей относительно осей губок.The purpose of the invention is to provide self-centering of two parts relative to the sponge axes.

Поставленна цель достигаетс тем, что в двухместных станочных тисках, содержащих корпус, две пары подвижных губок, привод выполнен в виде двух пар равновеликих двуплечих рычагов с зубчатой нарезкой на их контактирующих торцовых поверхност х, а рычаги свободными концами взаимодействуют с соответствующими губками и The goal is achieved by the fact that in double machine vices containing a body, two pairs of movable jaws, the drive is made in the form of two pairs of equally sized two-arm levers with serrated cutting on their contacting end surfaces, and the levers with free ends interact with the corresponding jaws and

10 установлены на ос х, размещенных в корпусе на одной пр мой, параллельной перемещению губок.10 are mounted on axles placed in the housing on one straight line parallel to the movement of the jaws.

На чертеже изображены предлагаемыеThe drawing shows the proposed

15 тиски, общий вид.15 vice, general view.

Двухместные станочные тиски содержат корпус 1, две пары подвижныхгубок 2, 3 и 4, 5 и привод 6, выполненный в виде двух пар равновеликих . двуплечих рычагов 7 и 8 с зубчатой нарезкой на их контактирующих торцовых поверхност х. Рычаги свободными концами взаимодействуют с соответствую щими губками и- установлены на ос х 9,Double machine vice contains the body 1, two pairs of movable sponge 2, 3 and 4, 5 and the actuator 6, made in the form of two pairs of equal size. two-arm levers 7 and 8 with serrated cutting on their contacting end surfaces. Levers free ends interact with the corresponding jaws and are mounted on axles 9,

Claims

25 placed in the housing 1 on one straight line, parallel to the movement of the jaws. The shoulders 10 of each of the levers fit into the grooves 11 of the corresponding jaw. At the free end of the screw of the drive 6, a drive coupling 12 is installed. The shape of the jaws corresponds to the shape of the workpiece 13. Double machine vices work as follows. When the clutch actuator 12 rotates, the drive screw rotates clockwise, the jaws 3 and 4 disperse and, while they move, rotate the levers 7 and 8 around the axis 9, causing the jaws 2 and 5 to move counter on time. A preliminary clamp, for example, left part 13 and stop the left pair of jaws 2 and 3. Then there is an accelerated movement of the jaws 4 and 5 until the right part 13 is fixed. When the coupling 12 is reversed, the screw of the drive 6 begins to rotate in the opposite direction and with equal resistance to unclenching the jaw 3 and 4, fascinated by sob The second arms 7 and 8, which, turning around the axes 9, move the outer jaws 2 and 5 in the direction opposite to that of the jaws 3 and 4. There is an expansion of the parts opposite to their fastening. The introduction of the proposed vice makes it possible, as compared to the known ones, to ensure the self-centering of two blanks relative to the sponge axes, regardless of the variation of the welding tolerances. The vise is simple in design, compact and easy to integrate into equipment. Claims Double machine vice containing a body, two pairs of movable jaws and a drive, characterized in that, in order to ensure the self-centering of parts relative to the axes of the jaws, the drive is made in the form of two pairs of equally sized two shoulders with serrated cutting on their contacting end surfaces, and the levers with their free ends interact with the respective jaws and are mounted on axes placed in the housing on one straight line parallel to the movement of the jaws.
