The invention relates to mechanical engineering and can be used, for example, in industrial work.

The aim of the invention is to expand the operational capabilities by changing the implementation of the leading pusher.

Fig. 1 shows a device for converting rotary motion into reciprocating section; FIG. 2 is a section A-A in FIG. 1,

A device for converting rotary motion into reciprocating comprises a guide 1, a leading follower, a screw 2 mounted on a shaft 3 on slots with the possibility of moving along it, placed in cable 1 of cable 4 with balls 5, one end of a cable It is connected with the pusher, and the other with the working airfoil (not shown). In addition, part of the guide is made in the form of a nut 6 fixed from rotation, and the cable 4 with the balls 5 is placed in the turns of the screw 2 and the nut 6.

which body is carried out through the hole 7 in the nut 6,

A device for converting rotary motion into reciprocating. Stepping works as follows.

When the shaft 3 rotates, the torque is transmitted to the screw 2 by means of, for example, a splined connection. Since the inner surface of the nut 6 and the outer screw 2 form a screw surface on which the balls 5 are located with the hole 4 passing through the hole in them, the screw 2 moves along the shaft 3 in one direction or the other depending on the direction of rotation of the shaft 3, With one direction of rotation of the shaft 3, the screw 2 pushes the balls 5 through the hole 7 in the nut 6. As a result, the balls 5 force the tool to operate,

When the shaft 3 rotates in the opposite direction, the balls 5 are wound on the screw 2, and the working element is actuated in the opposite direction.

DEVICE FOR CONVERTING ROTARY MOTION TO RETURN-AND-RECEIVER, containing a guide, a leading pusher mounted on a shaft, placed in a guide cable with balls, one end of which is connected to the pusher, and the other to the working body, which is connected with In order to expand operational capabilities, the lead pusher is a screw and mounted on the shaft on the splines with the ability to move along it, part of the guide is made in the form of a nut fixed from rotation, and the cable with balls placed in the turns of the screw and nut. organ, is carried out through the hole 7 in the nut 6. A device for converting rotational motion into reciprocating works as follows. When the shaft 3 is rotated, the torque is transmitted to the screw 2 using, for example, a spline connection. Since the inner surface of the nut 6 and the outer screw 2 form a helical surface on which the balls 5 are located with a cable 4 passing through the hole made in them, the screw 2 moves along the shaft 3 in one direction or another, depending on the direction of rotation of the shaft 3. When θ in one direction of rotation of the shaft 3, the screw 2 pushes the balls 5 through the hole 7 in the nut 6. As a result, the balls 5 force the working body to work. ' ₂₅ When the shaft 3 is rotated in the opposite direction, balls 5 are wound on the screw 2, and the working element is activated in the opposite direction.
