Description

one

The invention relates to mechanical engineering and can be used in various devices in which it is necessary to obtain intermittent movement of an executive body.

Known; maltny mechanism, containing the information, which is expelled in the form of a cylinder with a piston drive, crank with a girl, and interaction with the last means of transmission, and fixing link.

The purpose of the invention is to simplify the design, improve the dynamic characteristics, and expand the range of adjustment.

For this, the proposed Maltese mechanism is equipped with an additional Porshnevym drive and a two-arm lever, one "French" which is sariirno connected with the rods of the additional drive and the fi-xiying link, and the other With afivoschipom.

FIG. 1 shows the proposed Maltese Mechanism, a longitudinal section; FIG. 2 is a section along A-.4 of FIG. one.

The mechanism contains a base /, a cylinder 2 mounted on it and a piston 3, with which a rack 4 is rigidly connected, interacting with a gear wheel 5. a crank 6 rigidly connected to the latter.

with a bobbin 7, a Maltese cross 8 with grooves 9 and locking sockets 10, an additional piston actuator //, made in the form of a cylinder 12 and a rod 13 with which rigidly connected php: xator 14, double shoulders lever 15 and piston stroke limiter 16.

The mechanism works as follows.

In the initial position, the crank is 6 onen), and the bobbin 7 is under the Maltese cross 8, and the latch 14 is in the fixing slot 10. When the piston drive // is triggered, the Maltese cross 8 unlocks while the axial 7 is simultaneously entering the 7 azas 9 1iCiKoro cross 5. When moving the piston 5, the crank 6 gets a rotation, which by means of the bobbin 7 moves the Maltese cross 8 to one position. The piston actuator // is actuated again, fixes the Maltese cross 8 and removes the coil 7 from the groove 9. When the piston 3 of the piston 3 returns, reversible rotation is reported, and the bobbin 7 passes under the Maltese cross 8 and rotates to its original position.

The bobbin 7 can enter the grooves 9 in any intermediate position, which is achieved by changing the stroke of the piston 3 with the help of the stop 16. This allows rotation of the angles of rotation of the Maltese cross 8.
