Изобретение относитс к станкостроению и предназначено дл использовани в шoгooпepaциoнныx станках с ЧПУ и автоматической сменой инструмента.The invention relates to a machine tool industry and is intended for use in CNC machining machines with automatic tool change.

Известен многооперашгонлый стенокKnown multioperable walls

с ЧПУ, снабженный системой автоматической смены инстру1 {ентов, состо щей из инструментального магазина, встроенного в шпиндельную бабку, манипул тора и промежуточного носител инструментов, который снабжен механизмом захвата и предназначен дл транспортировки инструмента вдоль шпиндельной бабки между манипул тором и инструментальным магазиномCNC equipped with an automatic tool changer system consisting of a tool magazine embedded in the spindle head, a manipulator and an intermediate tool carrier that is equipped with a gripping mechanism and intended for transporting the tool along the spindle head between the manipulator and the tool magazine

К недостйтку известного станка еле- дует отнести то, что необходимость пе ремещени инструментов вдоль шпиндельной бабки приводит к такому расположению механизма захвата на промежуточном носителе, при котором чрезмерно увеличиваетс радиус захватного рычага манипул тора и, следовательно, растут динамические нагрузки при сохранении времени срабатывани механизма.The disadvantage of the known machine is that the need to move the tools along the headstock results in an arrangement of the gripping mechanism on the intermediate carrier, which excessively increases the radius of the gripping arm of the manipulator and, consequently, increases the load time of the mechanism.

Уменьшение радиуса захватного рычага Reducing the radius of the gripping lever

манипул тора может быть достигнуто путем разворота механизма захвата промех уточного носител по траектории, обеспечиваюшей огибание инструментом корпу и механизмов шпиндельной бабки. Дл сокрашени времени цикла смены промежуточный носитель должен стыковатьс с шпиндельной бабкой в любом месте на длине хода.the manipulator can be achieved by turning the mechanism of gripping the weft carrier's trajectory, which provides for the bending around of the toolbox and the mechanisms of the spindle head. In order to shorten the shift cycle time, the intermediate carrier must dock with the spindle headstock anywhere along the stroke.

Целью данного изобретени вл етс обеспечение разворота промежуточного носител по посто нной траектории движени относительно шпиндельной бабки в любом ее положении.The purpose of the present invention is to provide a turn of the intermediate carrier along a constant path of movement relative to the spindle head in any position thereof.

Согласно изобретению механизм захвата инструмента промежуточного носител установлен с возможностью поворота вокруг продольной оси носител , на наружной пилиндрической поверхности поворотной части которого выполнен винтовой паз взаимодействующий с неподвижно закрепленным на шпиндельной бабке нацрав ющим пальцем.According to the invention, the gripping mechanism of the intermediate carrier is installed with the possibility of rotation around the longitudinal axis of the carrier, on the outer pilindrical surface of the rotating part of which there is a screw groove interacting with the national finger fixed on the spindle head.

Claims

FIG. 1 shows the proposed carrier mounted on the frame; in fig. 2 - the same view from the front end of the spindle head; in fig. 3 section AA on fkg. 2; in fig. 4 shows a section BB in FIG. 3. The intermediate tool carrier includes a carriage 1 with an axis 2 on which a rotary drum 3 with a gripping mechanism 4 fixed on it is mounted for fixing the satellite with the tool 5 in the satellite carrier. The outer cylindrical surface of the rotary drum 3 is screw helical groove 6, which includes the guide pin 7 fixedly mounted on the spindle head 8. This embodiment of the rotary drum 3 ensures that the clamping device 4 rotates relative to the axis 2 of the carriage 1 by 180 when moving between LfTetanus carrier to the front end of the headstock 8 and returns to the starting position when retracting ppo; ezhytochIiogo carrier to instrumental Nome store. The angle of rotation of the drum 3 limits installed in turning the drum 3 screw 9 and the stop 10, attached to a fixed axis

2. The carriage 1, which is driven by the motor 11 through the spindle 12, is moved along two cylindrical guides 13, which are mounted on the body of the spindle head 8. At the ends of the lower guide, two rigid stops 14 are installed to restrict the stroke of the carriage 1. Directly removing the old and installing new tools in the spindle with a two-gripping lever is made of a manipulator 15 embedded in the tailstock 8. The tool is stored in a chain-type magazine 16, the links of which are the sockets for NTA. The proposed device works as follows. Upon a command from the control system to change the tool, the rack 17 of this goes back to the distance corresponding to the maximum length of the tool to be replaced or installed. At the same time, the hydraulic motor 11 is turned on, which, through the spindle screw 12, moves the carriage 1 from the intermediate waiting position to the tool change position. During this movement, the rotary drum 3 rolls over the guide pin 7, which enters the screw groove 6 and rotates the drum 3 by 180 ° Together with the rotary drum 3, the gripper 4 rotates, the transfer is fixed in it by the satellite with the tool 5 to the shift position. After stopping the carriage 1 on the hard stop 14, the gripping lever of the manipulator 15 rotates, picks up the tools in the spindle and in the satellite, turns on the nickname, removes 180 and inserts the new tool into the spindle, and the old one into the satellite. Then the gripping lever of the manipulator of the torus takes the initial position. This serves as a command to move the rack 17 forward to produce a new operation. At the same time, the motor 11, through the spindle screw 12, moves the carriage 1 to the magazine 16. The guide pin 7, interacting with the screw groove 4, turns the rotary drum 3 by 180 ° in the opposite direction to a position where further movement of the momentum carrier along the headstock is possible. After the guide pin 7 leaves the screw slot, the 4-position of the rotary drum 3 is determined by a screw 9, which abuts against the stop 1O. When moving the carriage 1 along the magazine 16, the satellite with the tool is installed in its socket. The carriage 1 continues to move to a stop on the rear hard stop 14. In this position, the grip 4 does not interfere with the movement of the chain of the tool magazine for locating the socket with the next tool. After installing the socket with the next instrument into the position of interaction with the intermediate carrier, the hydraulic motor 11 is turned on. Carriage 1 moves forward, removes the satellite with the instrument from the magazine slot and moves with it to the waiting position, in which the intermediate carrier is before issuing the new command from the control system. on tool change. Claims of the Intermediate Tool Carrier, equipped with a locking mechanism and intended for transporting the tool between a manipulator embedded in the spindle head of the machine and carrying out a tool change, and a tool magazine, characterized in that in order to ensure its rotation along a constant path of movement from relative to the spindle head in any position, the tool locking mechanism is mounted for rotation around the longitudinal axis of the carrier, on the outer cylindrical plate surface of which is formed a helical groove, which includes a fixedly mounted to the headstock guide finger.
