Изобретение относитс  к станкостроению, может быть использовано в металлорежущих станках с числовым программным управлением .The invention relates to a machine tool, can be used in machine tools with numerical control.

Известно по основному авт. св. № 707762 устройство дл  автоматической смены инструмента , содержащее кривощшшый и мальтийский механизм осевого перемещени  и поворота дв5псзахватного рычага смены инструмента.Known by the main author. St. No 707762 device for automatic tool change containing a crooked and Maltese mechanism for axial movement and rotation of the two-grip lever tool change lever.

Это устройство снабжено кулачком зажима инструмента, установленным соосно рычагу и кинематически св занным с водилом мальтийского механизма и кривошипом.This device is equipped with a tool-clamping cam, mounted coaxially to the lever and kinematically connected with the Maltese carrier and crank.

Кривощипный механизм имеет свободный ход до и после осевого перемещени  рычага смены инструмента.The crank mechanism has a free play before and after axial movement of the tool change lever.

Врем  свободного хода по циклу используетс  дл  управдени  зажимом инструмента П1.The cycle time is used to control the tool clamp P1.

Однако в известном устройстве дл  автоматической смены инструмента необходим)по точность ориентации инструмента в гнезде двухзахватного рычага обеспечивают величииами зазоров по диаметру захватной щейкнHowever, in the known device for automatic tool change it is necessary) in terms of the accuracy of orientation of the tool in the nest of the two-jaw lever, provide the magnitudes of the gaps along the diameter of the gripping pin.

инструмента, ее ширине и углу охвата в гнезде .tool, its width and angle of coverage in the nest.

Цель изобретени  - расширение технологических возможностей устройства.The purpose of the invention is to expand the technological capabilities of the device.

Указанна  цель достигаетс  тем, что в устройстве дл  автоматической смены инструмента металлорежущего станка захват двухзахватного рычага выполнен в виде подпружиненного ролика, установленного на рычаге, и защелки в виде поворотной призмы, шарннрно св 10 занной с толкателем, при этом ось симметрии призмы в рабочем положении проходит через центр ролика и инструмента.This goal is achieved by the fact that in the device for automatic tool changer of a cutting machine, the grip of the two-jaw lever is made in the form of a spring-loaded roller mounted on the lever, and the latch in the form of a rotary prism hinge-connected with the pusher, while the axis of symmetry of the prism passes in working position through the center of the roller and tool.

На фиг. 1 - изображено предлагаемое устройство без инструмента; на фиг. 2 - то же FIG. 1 - shows the proposed device without a tool; in fig. 2 - the same

ts с инс1рументом; на фиг. 3 - разрез А-А на фиг. 2.ts with the tool; in fig. 3 shows section A-A in FIG. 2

Устройство дл  автоматической смены инструмента содержит двухзахватный рычаг 1, каждый из захватов которого выполнш в The automatic tool changer device comprises a two-jaw lever 1, each of the grips of which is performed in

20 виде ролика 2 и защелки 3 в виде поворотной призмы.20 as a roller 2 and a latch 3 in the form of a rotary prism.

Claims (2)

Защелка 3 шарнирно св зана с толкателем 4, ось которого 5 входит в паз рычага 1. лик 2 расположен против защелки 3 и соеди нен с рычагом 1 набором плоских пружин Профили роликов 2 и защелки 3 соответствуют профилю захватной шейки инструмента 7, Смену инструмента осуществл ют следующим образом. При перемещении шпиндельной головки в позицию смены инструмент 7 вводитс  в гне до рычага 1, поворачива  при этом защелку 3 и перевод  шарнирно св занный с ним тол катель 4 в положение, указанное на фиг. The latch 3 is hingedly connected to the pusher 4, whose axis 5 enters the notch of lever 1. The face 2 is opposite to the latch 3 and connected to the lever 1 by a set of flat springs. The profiles of the rollers 2 and the latch 3 correspond to the profile of the gripping neck of the tool 7. The tool is changed in the following way. When the spindle head is moved to the change position, the tool 7 is inserted in the rot to the lever 1, while turning the latch 3 and moving the pivotally connected hinge 4 to the position indicated in FIG. 2. Защелка 3 и ролик 2, расположенный на ее оси симметрии (при введенном инструменте 7) охватывают захватную шейку инструмента 7 в трех точках, равномерно расположенных по окружности, и зажимают его за счет дефо мации пружин 6. В начале цикла смены инструмента производ т зажим инструмента 7 поворотом кулака 8, при этом положение защелки 3 фиксируетс  воздействием кулака 8 на толкатель 4. По окончании цикла смены кулак 8 устанавливаетс  в положение, изображенное на фигЛ. Ходом шпиндельной головки в рабочую зону инструмент 7 выводитс  из рычага 1 и пружина 9 возвращает защелки 3 в исходное положение, так как толкатель 4 в положении, изображенном на фиг. 1, не фиксируетс  кулаком 8. Таким образом, зажим инструмента поворотной призмой (защелкой) и подпружиненным роликом, профили которых соответствуют профилю захватной шейки инструмента, позвол Joт использовать известное устройство дл  креплени  инструмента с различной конфигурацией захватной части с равной надежностью. Формула изобретени  Устройство дл  автоматической смены инструмента по авт. св. N 707762, отличающеес  тем, что, с целью расширени  технологических возможностей, захват двухзахватного рычага выполнен в виде подпружиненного ролика, установленного на рычаге, и защелки в виде поворотной призмы, шарнирно св загшой с толкателем, при этом ось симметрии призмы в рабочем положении проходит через центр ролика и инструмента. Источники информации, прин тые во внимание при экспертизе 1. Авторское свидетельство СССР N 707762, кл. В 23 Q 3/155, 05.09.77.2. The latch 3 and the roller 2 located on its axis of symmetry (when the tool 7 is inserted) cover the gripping neck of the tool 7 at three points evenly spaced around the circumference, and clamp it due to spring deflection 6. At the beginning of the tool change cycle clamping the tool 7 by turning the knuckle 8, while the position of the latch 3 is fixed by the action of the knuckle 8 on the pusher 4. At the end of the shift cycle, the knuckle 8 is set to the position shown in FIG. By moving the spindle head into the working area, the tool 7 is removed from the lever 1 and the spring 9 returns the latches 3 to the initial position, since the pusher 4 is in the position shown in FIG. 1, is not fixed by the fist 8. Thus, the tool clamping with a rotating prism (latch) and a spring-loaded roller, whose profiles correspond to the profile of the tool's pickup neck, allows you to use a known device for fastening the tool with different configuration of the gripping part with equal reliability. The invention of the device for automatic tool change on the author. St. N 707762, characterized in that, in order to expand technological capabilities, the grip of the two-jaw lever is made in the form of a spring-loaded roller mounted on the lever, and the latch in the form of a rotary prism, hinged with the pusher, while the axis of symmetry of the prism in the working position passes through center roller and tool.
