(54) СИЛОВАЯ ГОЛОВКА(54) POWER HEAD

II

Изобретение относитс к станкостроению и может быть использовано в агрегатных станках и автоматических лини х.The invention relates to a machine tool industry and can be used in aggregate machines and automatic lines.

Известна плоскокулачкова силова головка , в корпусе которой смонтированы пиноль с инструментальным шпинделем, привод вращени шпиндел и механизм осевого перемещени пиноли, выполненный в виде кулачка, взаимодействующего с роликом, св занным с пинолью, и черв чной передачи 1.A plane-cam power head is known, in the case of which a quill is mounted with a tool spindle, a drive of spindle rotation and a mechanism for axial movement of the quill made in the form of a cam interacting with a roller associated with the quill and a worm gear 1.

Однако применение пневмо(гидро)цилиндра дл осуществлени ускоренных перемещений пиноли усложн ет конструкцию головки.However, the use of a pneumatic (hydro) cylinder to effect accelerated movements of the quill complicates the design of the head.

Цель изобретени - упрощение конструкции .The purpose of the invention is to simplify the design.

Поставленна цель достигаетс тем, что механизм осевого перемещени пиноли снабжен ползуном, несущим ролик, и рычагом, установленным с возможностью поворота и соедин ющим ползун с черв ком привода подач, смонтированным с возможностью осевого перемещени .The goal is achieved by the fact that the axial movement mechanism of the quill is equipped with a slider carrying the roller, and a lever mounted rotatably and connecting the slider with the feed drive screw mounted axially.

5Головка содержит корпус 1, в цилиндрической расточке которого смонтирована пиноль 2 со щпинделем 3, несущим инструмент 4. Шлицевой конец 5 щпиндел 3 через зубчатую передачу 6 соединен с приводом 7. В корпусе 1 смонтирован вал 8, соединенный5 The head includes a housing 1, in a cylindrical bore of which a quill 2 is mounted with a pin 3 supporting the tool 4. The slotted end 5 of the pin 3 3 via gear 6 is connected to the actuator 7. In the case 1 a shaft 8 is mounted, connected

через зубчатую передачу 9 с приводом 10. На валу 8 установлен черв чный винт 11, зафиксированный от поворота щпонкой 12 и соединенный через щарики 13 с муфтой 14. Черв чный винт 11 и муфта 14 установ- лены на валу 8 с возможностью осевого перемещени . through a gear 9 with a drive 10. On the shaft 8 there is a worm screw 11 fixed from rotation by the tongue 12 and connected through the balls 13 to the clutch 14. The worm screw 11 and the clutch 14 are mounted on the shaft 8 with the possibility of axial displacement.

Муфта 14 зафиксирована от поворота щпонкой 15 и соединена через палец 16 с поворотным рычагом 17. Рычаг 17 взаимодействует с ползуном 18, смонтированным сThe clutch 14 is fixed from rotation by the pin 15 and connected through the pin 16 to the rotary lever 17. The lever 17 interacts with the slide 18, mounted with

Claims

20 the possibility of longitudinal movement in the groove of the housing 1 and the connected tooth 19 with quill

2. A worm screw 11 engages with a gear wheel 20 mounted on a shaft 21. A shaft 21 is mounted in a bearing assembly of a hub 22 of housing 1. A spiral-shaped cam 23 is fixed to the gear wheel 20 and provided with a radial slot, in which the roller 24 enters, mounted on the axis 25, mounted on the slider 18. On the shaft 21 from the outside fixed ratchet wheel 26, interacting with a spring-loaded latch 27. The head works as follows. When the drive 7 is turned on, the rotation from the drive is transmitted through gear 6 to the spindle 3 with tool 4. When the drive 10 is turned on, rotation from the drive is transmitted through gear 9 and the shaft 8 to the worm screw 11. Due to the fact that the cam 23 is impeded by the rotation of the roller 24, entering the radial groove of the cam, and consequently, the wheel 20, fastened with the cam 23, is braked, the worm screw 11 moves with the coupling 14 axially along the shaft 8. The coupling 14, interacting with the finger 16, rotates the lever 17. After choosing for ora t (FIG. 2) of the lever head 17 comes into contact with the surface 28 of the slider 18 and the slider 18 starts pere.meschenie which the tooth 19 moves through the tailstock 2 with schpindelem

3. This is the way to quickly bring tool 4 by the amount H to the workpiece. After the roller 24 leaves the groove of the cam 23, the clutch 14 abuts against the wall of the housing 1, the axial movement of the worm screw 11 stops and the wheel 20 begins to rotate with the cam 23. The outer spiral-shaped surface of the cam 23 with roller 24 starts the working feed of the quill 2 with the pin 3 and tool 4 on the value of HI. After turning the cam 23 to a 360 ° angle, the tool feed is terminated.

4. To reverse the movement of the quill 2 with the pinch 3, the rotation of the actuator 10 is reversed. The latch 27 through the cam 26 brakes the shaft 21 with the wheel 20 and the cam 23, the worm screw 11 with the clutch 14 moves along the shaft 8 to the initial position and the lever 17, interact with the head 29 of the slide 18, retracts the quill 2 with the rod 3, and the roller 24 enters a cam slot 23. The invention simplifies the design of the head. Claims of the invention A power head, in the case of which a quill with an instrumental spindle is mounted, a spindle rotation drive and a quill axial movement mechanism, made in the form of a kulka interacting with the roller associated with the quill, and a worm gear, characterized in that simplifying the design, the axial movement mechanism of the quill is provided with a slider carrying the roller, and a lever mounted for rotation and connecting the slider with the feed drive screw mounted for axial movement neither Sources of information taken into account in the examination 1.
