J Изобретение относитс к области станкостроени и может быть использовано в металлорежущих станках с автоматической сменой инструментов.J The invention relates to the field of machine tool construction and can be used in machine tools with automatic tool change.

Известно устройство дл автоматической смены инструментов на металлорежущих станках, например токарных, содержащее смонтированное на суппорте станка приспособление дл креплени инструментодержателей , магазин инструментов и автооператор 1.A device for automatically changing tools on metal-cutting machines, such as lathes, containing a tool holder fixing device, a tool shop and an auto-operator 1 is known.

Недостатком этого устройства вл етс ограниченность его технологических возможностей .A disadvantage of this device is the limitations of its technological capabilities.

Целью изобретени вл етс расширение технологических возможностей устройства .The aim of the invention is to expand the technological capabilities of the device.

Дл достижени цели устройство дл автоматической смены инструментов на металлорежущих станках снабжено направл ющим барабаном коммуникаций и переталкивателем дополнительного инструментодержател в магазин инструментов, причем последний имеет соответствующую перегрузочную позицию, а направл ющий барабан установлен на корпусе автооператора.To achieve the goal, the device for automatic tool changer on metal cutting machines is equipped with a communications guide drum and an additional tool holder pusher to the tool magazine, the latter having an appropriate reloading position, and the guide drum is mounted on the body of the operator.

Кроме того, направл ющий барабан выполнен в виде двух дисков, расположенных на дополнительно смонтированной на корпусе автооператора оси, причем верхний диск установлен на ней с возможностью поворота.In addition, the guide drum is made in the form of two discs located on an axis additionally mounted on the body of the operator, with the upper disc mounted on it with the possibility of rotation.

На фиг. 1 изображен общий вид устройства дл автоматической смены инструментов; на фиг. 2 - вид А фиг. 1; на фиг. 3 - переталкиватель дополнительного инструментодержател ; на фиг. 4 - направл ю Q щий барабан; на фиг. 5 - фиксатор. FIG. 1 shows a general view of an apparatus for automatically changing tools; in fig. 2 - view A of FIG. one; in fig. 3 - additional propeller tool holder; in fig. 4 - directional Q drum; in fig. 5 - lock.

Устройство содержит установленное на суппорте 1 станка приспособление 2 дл креплени инструментодержателей 3, имеющее Т-образный прихват 4 дл зажимаThe device contains a fixture 2 mounted on the support 1 of the machine for fastening tool holders 3, having a T-shaped clamp 4 for clamping

Claims

15 of the installed tool holder 3. Each tool holder 3 has a prism that can be gripped on an auto-operator 5, rising and turning 180 ° in both directions. On the longitudinal carriage of the machine tool shop is located 6 in the form of an endless chain conveyor. The fastening of tool holders in the magazine is carried out using locking mechanisms. One of the store sockets (reloading station) serves to load into it an additional tool holder 7 stored outside the store. Therefore, there is no fixation mechanism in this nest; instead, a special code strip is attached to the chain link of this position, which serves to identify the special position of the store when searching for it. Another slot of the magazine (idle position) is reserved for installing the spent tool holder 3 therein before installing the additional tool holder 7. To identify the idle position of the magazine, there is an identification block. It is a set of photo relays, respectively, located in the magazine case in the unloading position. A bracket 8 is attached to the body of the tool magazine 6, on which the tool holder 9 of the tool holder 7 is located in the reloading position of the magazine. The choke 9 consists of a hydraulic cylinder 10, a slide 11 connected to the hydraulic cylinder rod by a bar 12. On the slide there is a prism 13 of the installation of the tool holder 7 and a clamp 14. The movement control of the rod of the hydraulic cylinder 10 is performed using limit switches. The tool holder 7 is provided with additional bevels under the grip of the auto operator 5. On the axis 15 mounted on the body of the auto operator 5, the guide drum 16 of the communications of the tool holder 7 connected to the power supply systems of the machine tool is installed. The drum 16 is made in the form of two disks, the upper of which 17 is movably mounted on the axis 15, and the lower 18 is rigidly fixed on it. The device works as follows. At the command of the program, the idle position recognition unit is turned on and searched for to load the spent tool. This unit sends a signal to stop the drive rotation store. At the command of the program, the identification unit is turned off and the auto-operator 5 transfers the spent tool from the device 2 to the free slot of the magazine (idle position). Further, by command from the program to drive. rotation of the magazine, the search for an overload position begins. When the store chain rotates, the code strip attached to the chain link of the overload position, by acting on the microswitch of the search unit, stops this position in the loading position. On command from the program, the propeller 9 starts working. The rod of the hydraulic cylinder 10, the bar 12, drives the slide 11. The latter move the tool holder 7 fixed on the prism 13 towards the store. When the slide 11 moves, the pin of the retainer of the retainer 14, abutting against the wall of the magazine case, pushes the retainer from the tool holder 7. At the end of the extension, the stop presses the microswitch roller, which signals that the overload position is loaded. The shank of this tool holder, due to the presence of additional bevels, enters the decompressed grip of the auto-operator 5. The gripper is compressed and the tool-carrying file 7 is transferred from the reloading position of the magazine to the tool stand of the machine. When turning the transfer mechanism, hoses, toward & or other flexible communications, rotate the disk 17 of the drum 180 °. The removal of the tool holder to the overload position and unloading of this magazine position is carried out in reverse order. The use of the proposed device in the machine tools allows the tool holder to be automatically installed in the machine support connected with the power supply systems of the machine, which significantly eases the technological capabilities of the machine and increases the efficiency of its use. Claim 1. A device for automatically changing tools on metal-cutting machines, such as turning machines, comprising a tool holder fixture mounted on a machine support, a tool magazine and an auto-operator, characterized in that in order to expand technological capabilities by using additional tool holders connected by communications with the power systems of the machine, it is equipped with a guide drum communications and pushing additional tool The holder is in the tool magazine, the latter has a corresponding overload position, and the guide drum is mounted on the body of the operator.

2. The device according to claim I, characterized in that the guide drum is made in the form of two disks located on an axis mounted on the upper disk of the operator’s operator, which is additionally mounted on the housing, mounted on it with the possibility of information sources taken into account during the examination I.
