Изобретение относитс к станкостроению и может быть использовано в токарно-револьверных станках с горизонтальной осью револьверной головки дл повышени надежности ее фиксации. The invention relates to a machine tool industry and can be used in turning-turret lathes with a horizontal axis of a turret to increase the reliability of its fixation.

Известен револьверный суппорт с горизонтальной осью револьверной головки, содержащий устройство дл поворота револьверной головки и фиксирующее устройство в виде муфты, имеющей три зубчатых венца с торцовьпли зубь ми, первый венец которой закреплен в корпусе суппорта, второй закреплен концентрично первому на валу револьверной головки, а третий установлен с возможностью перемещени вдоль вала револьверной головки и св зан с приводом Cl 3 A turret caliper with a horizontal axis of a turret is known, containing a device for rotating the turret head and a locking device in the form of a coupling having three toothed rims with face and teeth, the first crown of which is fixed in the caliper case, the second one is fixed concentric to the first on the shaft of the turret and the third mounted to move along the shaft of the turret and connected to the Cl 3 drive

Однако така конструкци не позвол ет сохран ть необходимый нат г в сопр жени х зубчатых венцов в процессе длительной (эксплуатахшн вследствие неизбежного неравномерного износа поверхностей зубьев неподвижных венцов.However, such a structure does not allow to maintain the necessary tension in the mates of the toothed rims during a long process (operation due to the inevitable uneven wear of the tooth surfaces of the fixed rims.

обусловленного различной жесткостью закреплени венцов относительно корпуса суппорта, и поэтому не обеспечивает надежной фиксации револьверной го- . ловки.due to the different stiffness of the fastening of the rims relative to the body of the caliper, and therefore does not provide a reliable fixation of the turret go-. adroit.

Целью изобретени вл етс повьшение надежности фиксации револьверной головки.The aim of the invention is to increase the reliability of fixation of the turret.

Поставленна цеЛь достигаетс тем, что на наружной и внутренней поверхнос10 т х одного из концентрично установленных венцов выполнены чередующиес параллельно его оси проточки, причем зубь этого венца в расфиксированном состо нии смещены относительно зубьев The goal is achieved by the fact that on the outer and inner surfaces 10 tons x of one of the concentrically mounted crowns alternating parallel grooves are parallel to its axis, and the teeth of this rim are in the unlocked state shifted relative to the teeth

Claims

The turret caliper contains body 1, in which shaft is installed on supports, shaft 2 with turret 3, 397 bearings with preload, adjustable nut 4, tapered roller bearings 5 and 6 are mounted. Shaft 7 is fixed on shaft 2 and is connected drive rotation turret (not shown). The mechanism for fixing the turret 3 consists of three gear rims with end teeth: a Vienna 8, a gesture fixed to the body of a revolving caliper, a concentric rim 8 of the crown 9, on the outer and inner surfaces of which are alternating parallel to its axis of the groove, forming an elastic element 1O, allowing axial displacement of the teeth of this ring, which is relatively rigidly fixed on the shaft 2 of its part 11, and ring 12, which moves along the shaft 2 with the drive, the tooth of the ring 9 is unlocked in the unlocked state about the teeth of the ring 8 in the direction of the bench 12 by an amount corresponding to the magnitude of the deformation of the elastic element 10 in the fixed state of the turret. The crown 12 is connected to the piston 17 of the hydraulic cylinder 18 fixed to the body 1 of the turret support by means of a pipe 13, a beam 14 and a pusher 15 through a thrust bearing 16. A spring 19 is installed between the shaft 2 and the beam 14. The revolving caliper works as follows. In order to fix the revolving head 3, the oil is fed into the right cavity of the hydraulic cylinder 18, and from the left cavity goes to the drain. The piston 17 moves the pusher 15, the beam 14 and the pipe 13 together with the crown 12 to the left, compressing the spring 19. When an atom first, the teeth of the crown 12 are connected with the teeth of the crown 9, and after the deformation of the elastic element 1O, and with the teeth of the crown 8. This provides the necessary simultaneous tension in conjugation of the teeth of the crown 12 with the teeth of the crowns 8 and 9. The magnitude of the tension in the conjugation of the teeth of the crowns 9 and 12 is determined by the force of the deformed elastic element 10, and the magnitude of the tension in the coupling of the teeth crowns 8 and 12 are determined by the difference in the force generated by the hydrocyls Ndrom 18 and the magnitude of the efforts of the elastic element 10 and the spring 19.. Thus, the shaft 2 with a turret 3 will be rigidly fixed in the housing 1 of the turret caliper. To release the turret 3, the oil is fed into the left cavity of the hydraulic cylinder 18, and from the right cavity goes to the drain. The spring 19 through the beam 14 and the pipe 13 retracts the crown 12 to the right, as a result of which its teeth are disengaged from the teeth of the crowns 8 and 9. In the unlocked state, the shaft 2 with the turret 3 can be rotated when changing positions or when making circular working gear gear 7 from its drive. This embodiment of the caliper povyuit reliability of fixation of the turret. The invention of the revolving caliper with a horizontal axis of the turret, containing a device for rotating the turret head and a locking device in the form of a coupling having three toothed crowns with face teeth, the first crown of which is fixed in the caliper case, the second is fixed concentric to the first on the shaft of the revolving head the third is movably mounted along the shaft of the revolving gun; it is associated with a drive, characterized in that, in order to reliably fix the turret head, on The outer and inner surfaces of one of the concentrically mounted crowns are alternated parallel to its groove axis, and the teeth of this crown are mixed in the unlocked state relative to the teeth of the concentric set of the other crown in the direction of the third movable crown.
