The invention relates to the field of machine tools.

Known turret caliper turning machine with numerical control, including a multi-spindle turret head, its rotation mechanism, its fixation mechanism on the gears and the rotation drive tools revolver golbvki containing the drive shaft, implementation of the clutch end coupling coupling with the coupling half of the shaft shaft, tools, shaft shafts, tools, shaft shafts, and a shaft shaft.

A disadvantage of the known turret is the relative complexity of its design.

The purpose of the invention is to simplify the caliper design.

To achieve this goal, the drive shaft is fixed in the axial direction, and its end coupling half is spring-loaded and installed with the possibility of axial movement.

The drawing shows the proposed turret caliper. - In the case 1 of the turret caliper, an axis 2 is mounted on which the turret head 3 is placed, a worm gear 4 with a screw 5 of a turret rotation drive, a disk 6 with a pre-latch slot, a cylinder of a pistol 7 with a piston, a positioning sensor 8 of the turret head .

In parallel with axis 2 against the working position, a drive roller 9 is placed in housing 1 with a drive pulley 10 and a gear half coupling 11 influenced by a spring 12. In the slots of the turret 3 there are holders 13 for a stationary tool or a holder 14 for a rotating tool. Intermediate rollers 15 with bevel gears and toothed coupling halves 16 are also mounted in the head 3;

coupling the holders 14 with the drive roller 9. The number of intermediate rollers 15 may correspond to the number of tool jacks or be less if the number of holders with a rotating tool is limited.

On the case 1 of the turret, the pre-locking valve 17 is also mounted, which stops the drive of the turret rotation 3 at the command of the positioning sensor 8. For final fixation of the turret

3 on the housing 1 are mounted gear rims 1B.

The operation of the revolving caliper mechanisms is as follows. At the command of the CNC, the switching cycle of the turret starts: the pre-release valve 17 pulls the lock out of the slot b of the disk, the piston 7 of the clamp cylinder moves to the left, axis 2 is pulled along with the turret 3 attached to it, thereby disengaging the gear rims 18 and on the floor of the coupling 16 and 11 of the mechanisms of rotation of the tool, while the spring 12 sends the semi-coupling 11 to the extreme left position. After that, the turret starts to rotate from a rotation mechanism consisting of a hydraulic motor (not shown in the drawing), a screw 5, a worm gear 4, which sits on the splines of the axis 2 of the turret head 3.

The rotation continues to the set position along the shortest path until the positioning sensor 8 issues a stop command. After this, the prefix: the latch lock 17 falls into the groove of the disk 6 and the piston 7, the cylinder of the clamp moves to the right, and the ocji 2 with the turret 3 sitting on it is carried along.

The movement to the right of the piston 7 continues until the gear rims 18 are engaged with each other.

In so doing, the coupling halves 16 of the roller 15 are engaged with the coupling half 11 of the roller 9, thereby compressing the spring 12.

The positioning sensor 8 includes a tool rotation drive motor (not shown) if a rotating tool is provided at this position. If the tool is stationary, the positioning sensor 8 does not turn on the electric motor.

Thus, for the mechanical coupling of the tool holders 14 to the drive roller 9, no additional mechanisms (electromagnet, hydraulic cylinder, etc.) are required, and for switching the rotation of the tool drive motor no end switches are required, as the position sensor is used. always available in one form or another on a turret caliper.

Simplifying the design of the turret caliper will increase its reliability and durability.

NUMERICAL SOFTWARE CONTROL LATCH ROTARY SUPPORT, including a multi-spindle individual turret, a mechanism for its rotation, a mechanism for securing it to the gear crowns and a drive for rotating the turret tools, containing a drive shaft that engages the end coupling half-shaft with the tool holders that, in order to simplify the design, the drive shaft is mounted motionless in the axial direction, and its end coupling half is spring-loaded and installed with the possibility of axial movement. X sh x m> 3 on the housing 1 mounted gears, crowns 18. The work of the mechanisms of the revolving caliper is as follows. At the command of the CNC system, a switching cycle of the turret begins: the pre-lock valve 17 pulls the lock out of the groove of the disk 6, the piston 7 of the clamp cylinder. 18 and the coupling halves 16 and 11 of the tool rotation mechanisms, right this spring 12 πό15 sends the coupling half 11 to the leftmost position. After this begins the rotation of the turret from the rotation mechanism, consisting of a hydraulic motor (not shown in the drawing), 2Q of the worm 5, the worm gear 4, sitting on the splines of the axis 2 of the turret 3. The rotation continues to the specified position along the shortest path until position sensor 8 sends a stop command. After that, the preliminary latch 17 engages in the groove of the disc bi piston 7 of the clamp cylinder moves to the right, dragging ocj, 2 with the turret 3 sitting on it. The movement to the right of the piston 7 continues until the ring gears 18 are engaged. In this case, the coupling halves 16 of the roller 15 35 are engaged with the coupling half 11 of the roller 9, while compressing the spring 12. The positioning sensor 8 includes an electric motor for rotating the tool (not shown in the drawing), if a rotating tool is provided in this position. If the tool is stationary, the positioning sensor 8 does not turn on the electric motor. 45 Thus, for the mechanical coupling of the tool holders 14 with the drive roller 9, no additional mechanisms are required (an electromagnet, a hydraulic cylinder, etc.), and end switches are not required for turning on the rotation of the tool’s electric drive motor, since a position sensor is used, always available in one form or another on the turret. Simplification of the design of the turret support will increase its reliability and durability.
