Description

The invention relates to mechanical engineering, in particular to rodless pneumatic actuators, and can be used as a drive for the movement of working bodies in robots and manipulators.

The aim of the invention is to increase reliability.

FIG. 1 schematically shows a pneumatic cylinder, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

The pneumatic cylinder comprises a housing 1 with a longitudinal groove 2 and guide tracks 3 and 4, a piston (not shown) mounted in the housing 1 and connected through a longitudinal groove 2 with a slider 5 made of a ferromagnetic material. In addition, the cylinder includes a device for closing the groove 2, made in the form of brackets 6 and 7, located on both sides

In the initial position (Fig. 1), the slider 5 interacts with the magnets 8 of the bracket 6, and the bracket 7 is in the middle part of the housing 1. When the piston moves along with the slider 5 to the left, the bracket 6 is moved in the same direction with the slider 5 before contact with the stops 9 and 10. The slider 5 freely passes over the stops 9 and 10, and the clip 6 is held back by the stops 9 and 10 and remains in the middle part of the housing 1 and secures it from the possible opening of the slot 2. The clamp 7 moves the slider 5 to the extreme left position.

When reversed, the slider 5 together with the staple 7. C- moves to the right until the staple 7 is in contact with the stops 9 and 10, and then the slider 5 moves with the staple 6.

Thus, constantly one of the brackets

the slider 5, permanent magnets 8, located in the middle part of the housing 1,

which more reliably keeps the body 1 from opening the groove 2.

stapled in brackets 6 and 7 and installed opposite poles relative to the slide 5, and stops 9 and 10, located in the middle part of the housing 1 on both sides. Staples 6 and 7 are made of a diamagnetic material, and on the side opposite to the slider 5, ferromagnetic plates 11 and 12 are fixed on them, closing the magnetic flux at the time of the interaction of the magnets 8 with the slider 5. The stops 9 and 10 are located on the body in such a way that that they provide free movement of the slider 5 and prevent movement of the clips 6 and 7. The travel clearance between the surfaces of the guide tracks 3 and 4 and the clips 6 and 7 is slightly larger than the travel clearance between tracks 3 and 4 and the slider 5.

Depending on the length of the housing 1, the number of brackets 6 and 7 may be four or more. According to the number of brackets 6 and 7, the stops 9 and 10 can be located with a quarter and less than the length of the cylinder.40

g nemo cylinder works as follows.

Invention Formula A pneumatic cylinder comprising a housing with a longitudinal groove and guide tracks, a piston mounted in the housing and connected through the groove to a slide, cooperating with the guide tracks, and a groove closing device, characterized in that the groove closing device is made in the form of brackets located on both sides of the slider and covering the case, permanent magnets placed in the brackets and installed opposite poles relative to the slide and stops located in the middle part of the case, The slider volume is made of ferromagnetic material, and the brackets are made of diamagnetic material and mounted for movement along guide tracks and alternately interacting with the stops and the slider. In the initial position (Fig. 1), the slider 5 interacts with the magnets 8 of the bracket 6, and the bracket 7 is in the middle part of the housing 1. When the piston moves along with the slider 5 to the left, the bracket 6 is moved in the same direction with the slider 5 before contact with the stops 9 and 10. The slider 5 freely passes over the stops 9 and 10, and the clip 6 is retained by the stops 9 and 10 and remains in the middle part of the housing 1 and secures it from the possible opening of the slot 2. The bracket 7 is moved by the slider 5 to the extreme left position. When reversed, the slider 5 together with the staple 7 moves to the right until the staple 7 contacts the stops 9 and 10, and then the slider 5 moves along with the staple 6.
