move the executive to step. The aim of the invention is to improve the performance of the device by providing a latching speed. When moving through the drive drum 4 in the direction Y of the executive body 3 to the left, it turns through the spring-loaded stop 24 lever 8, on which the spring-loaded collar is pivotally attached. At the ratchet mechanism and spring-loaded rocker arm 15, with grooves 17 and 18 performed on one of its shoulders. through the interaction of the groove 17 with the stop 21 clamps removes it from the hole of the rail 7 ratchet

the mechanism intended to move the actuator 3 in the direction X, and the pawl 9, engaging with the rack 7, moves the actuator 3 to the step. At the end of the turn one shoulder of the head 15 passed the distance B exposed by the stop 23 fixed in the housing 1, it turns, the stop 21 of the retainer extends from the groove 17 of the rocker arm 15, and under the action of the spring 22 the retainer drops into the hole of the rail 7, thereby fixing

executive body 3 but dy position. After working at all positions, the executive body moves to its original position. By moving the rocker arm 15 9 to direction B by engaging the stop 21 of the retainer with the inclined groove 18 of the rocker arm 15 and the pin 16 mounted on the dog 9 with the arm of the rocker arm 15, the dog 9 and the retainer are simultaneously removed from the joint with the rail 7. P. f-ly, 2 ill.

The invention relates to mechanical engineering and can be used in various structures, in which the actuator is moved to a step.

The aim of the invention is to improve the performance of the device by providing quick fixation and convenience of returning the ratchet mechanism to its original position when using it for linear movement due to simultaneous removal of the lock and the pawl.

Figure 1 shows the device, top view; figure 2 - section aa in Fig, 1.

The device for moving the actuator includes a housing 1, along the guides 2 of which the actuator 3 moves in the Y direction from a power agency (not shown) by means of an actuator made in the form of a drum 4, protrusions mounted to cooperate with the anvil 5 mounted on the actuator 3. The guides 2 are secured in the carriage b, mounted for movement in the X direction relative to the housing 1, for this purpose the device comprises a ratchet mechanism including the rail 7 with holes, lever 8 and dog 9 attached to the carriage. The lever 8 is spring-loaded by spring 10 and can be rotated on axis 11. Axle 12 is connected to lever 8 by axis 12 of dog 9 and spring-loaded spring 13 and 14. On dog 9 there is a pin 16, and The rocker arm 15 has two pizzas 17 and 18, and the groove 18 is inclined. A cup 19 is fixed to the housing 1 with a latch 20 installed in it with a stop 21 and a spring 22, Adjustable stops 23 and 24 are installed in the housing 1 and on the lever 8 Adjustable stop 23 serves to set the distance 8 to provide a minimum and maximum ny step move the executive body 3. L - minimum

the size at which raksfiqi of the slats with the pawl does not occur at the g -, maximum pitch, On the executive body 3 a handle 25 is installed.

The device works as follows.

From the power body through the drum 4, which interacts with its projections with the stop 5, the executive body 3

moves to the left in the Y direction. At the same time, it presses on the adjustable stop 24 mounted on the lever 8. The lever 8 rotates on the axis 11, so the rocker 15 moves the stop 21 along with the lock

20, and the dog 9 goes idle a, on which the latch 20 leaves the hole of the rail 7. Then the dog 9 enters the latch with the rail 7 and moves it along with the carriage to step nt, where, 2,3, ..., at

depending on the distance b, the guides are set by the stop 23. The yoke 15, the distance b is rotated, rotates around the axis 12, with the finger coming out of the groove 17 of the rocker arm and the latch 20 by the spring

22 is inserted into the opening of the rail 7, corresponding to a predetermined step, thereby fixing the carriage 6 in place of this position. When moving the Executive body 3 through the drive drum 4 to the right in

the direction Y, the lever 8 by the spring 10 returns to its original position, with the stop 21, slipping along the plane of the rocker arm 15, falls into its groove 17, and the dog 9 engages with the rail 7, After

works at all positions the carriage 6 returns to its original position. To do this, move the rocker 15 in the direction of arrow B, the yoke .15 turning around the axis 12 and interacting with the dog 9 via the pin 16, pulls the dog 9 out of engagement with the rail 7, and the slanting groove 18 of the yoke 15, interacting with the stop 21 of the retainer 20,

removes the last of the orifice of the rail 7. After that, the carriage 6 moves by the handle 25 in the direction of the arrow B to the initial position. Then the cycle repeats. Claim 1. A device for moving an actuator, comprising a housing, a driving ratchet mechanism, a spring-loaded dog which is mounted on a swing arm, kinematically connected by a t4 lock, and two stops, one of which is mounted on the lock, and the other is adjustable and designed to change the step of movement, characterized in that, in order to increase the productivity of the device by increasing the speed of fixation, the kinematic connection of the lock with the lever is made Aa 0 five in the form of a rocker arm hinged on the last one, which is disposed to communicate with one of its shoulders by means of a groove made therein with an emphasis of the retainer, and the other with an adjustable stop mounted in the device body, the retainer, the lever and the rocker arm being spring-loaded relative to the body. 2. The device according to claim 1. Distinguished from the fact that an additional inclined groove is made in the rocker arm, designed to interact with the retainer stop, and the dog is connected to a pin inserted into the device, which is interoperable with one of the rocker arms 21 W 15 FIG. 2
