The invention is designed for clockwork and is intended for use in watch systems and in autonomous watches with automatic correction of readings on accurate time signals. The electric clock is known, with a correction device, containing a clock mechanism with an actuator, an indicator, an actuator of the correction device, performed) as a slider, kinematically connected with a lead screw and driven by a dc electric motor TI A disadvantage of the device is the cno-J curvature that, when the water of the correction assembly mechanism, in addition to the DC motor, contains a reducer, a lead screw with a cross-cutting thread, guides for moving the slider. The closest to the invention is a device comprising a clock mechanism with an idler, a clock mechanism, an actuator drive, a correction unit, a correction unit made in the form of a cantilever and a ratchet wheel with counter-directed teeth, a piezoelectric screw switch and a gearbox connecting watch fur, low 2 The disadvantage of this device is also the difficulty that the driver has in the presence of two engines - separately for driving the mechanism of the correction unit, as well as in the presence of wines This is a switching element. The purpose of the invention is to simplify the design, electric clock with a correction device and increase the reliability of the correction. The goal is achieved by the fact that in electric hours with a correction device, containing a clock mechanism with an indicator and; a booster electric machine, a correction unit, a switch and a reducer, the drive is connected to the COMJM mechanism and the correction unit through the block made in the form Two gear wheels, coaxially located on the adjustable axis and the elastic console of the drive interacting with them, one of the wheels mounted on the corrected axis freely and connected with the indicator, and the second one is stationary. ; In the preferred embodiment, the switch is made in the form of a piezoelectric element of rectangular cross section, and the elastic arm has an elliptical cross section. The drive of the clock mechanism and the electric clock correction assembly is carried out by a single piezo motor. The electrical trains are equipped with a switching unit of the drive unit, made in the form of a piezoelectric element of rectangular cross section, excited by time signals. FIG. 1 shows the structure of the proposed device; in fig. 2 is a view A of FIG. 1 (the position of the console and the switching element when the correction device is in operation, and the dotted line with the correction device not working, Fig. 2); in fig. 3 section bb in fig. one; in fig. 4 and 5 wheel structures in two planes; in fig. 6 shows a section B-B in FIG. 5, the electric clock with a corrective device consists of a 1 axis adjustable clock mechanism 2, on which is placed a block consisting of a gear 3 that is loosely fitted on axis 1 with ratchet end teeth and a hard-toothed gear 4. The piezo element 5 is connected to AC voltage source and is hingedly connected with console 6 of elliptical section (Fig. 3), located in the same plane with gear wheels 3 and 4. Console is in kinematic connection with gearbox 7. There are 4 teeth on two halves of gear teeth. directed oppositely and separated by a depression formed by the working surfaces of two adjacent teeth of different directions. The piezoelectric element 5 and the console 6 pivotally connected with it constitute a single vibromotor of the clock mechanism and the mechanism of the correction unit.

Switching piezoelectric element 8 of straight angle section It is used to turn off the drive of clockwork 2 and turn on the drive of the correction unit.

The drive unit of the clock mechanism and the mechanism of the correction unit operates as follows.

In the absence of time signals, the console 6 of the elliptical section is locked with the teeth of the ratchet wheel 3, which sits freely on the adjustable axis 1. At the same time, an alternating voltage is applied to the electrodes of the piezoelectric element 5, as a result of which its free end oscillates with a fixed fixed end. Through a hinge 9, a count & two movement is communicated to the free end of the console 6 of an ellS-shaped section, which, acting on the tooth of the count & 3, rotates the wheel, and with it the indicator of the clock mechanism 2 through the gearbox 7.

At the time of the entry of accurate time signals, a constant voltage is applied to the electrodes of the switching element 8, and as a result, the switching element 8 is bent. With this catch 10, the free end of the oscillating console 6 is pulled out of the hook &

It is attached to the teeth of the ratchet wheel 3 and is engaged with the ratchet teeth of the wheel 4, which is rigidly fixed to the correction axis layer 1.

The sign of the correction depends on the direction of the ratchet teeth of the wheel 4, with which the free end of the console 6 engages, and the correction of the readings of the indicator continues until the free end of the console 6 coincides with a flat depression separating the counter-directed teeth of the wheel 4.. , After completing the adjustment of the clock readings, the supply of constant voltage to the electrodes of the piezo switching element 8 is stopped, and the free end of the arm of the elliptical section is engaged with the teeth of the snoring wheel 3.

The combination of the indicator drive and the correction unit in the same block allows using only a single motor, and releasing the switch in the form of a piezo element of a rectangular cross section simplifies its manufacturing technology.

The elliptical section of the elastic arm increases the reliability of operation of the unit at the moment of switching due to its rigidity with respect to a small axial section, which is located perpendicular to the switch plane.
