Definitions
- the present invention relates to a linear unit for producing a mechanical force by compressed air.
- the present invention relates Positioning means for stopping the force-emitting parts of the working unit at least one job.
- a linear unit according to the preamble of claim 1 is known from the Prospectus "RexMover" (by AB Rexroth Mecman, print number 000-120-710-2, from 15. 11. 1999).
- the work unit comprises a rodless cylinder with a mounted on the cylinder housing slider.
- the slider is along the cylinder guided by a roller bearing guide rail and stands with a in the Pneumatic cylinder located piston in conjunction to the slider in Dependency with a reciprocal action of the piston by compressed air to move.
- EP 0 078 496 A1 discloses a generic linear unit which consists of a rodless pneumatic cylinder with a slider that passes over a Guide rail is guided on the cylinder, and the internal piston through alternating action is driven. Furthermore, as a positioning means for Stop the linear movement of the slider one parallel to the guide rail at Pneumatic cylinder arranged stop rod provided on which here two attacks are provided with integrated shock absorber means in the form of elastomeric elements. However, such shock absorbers provide only a very limited Cushioning effect.
- the invention provides Positioning means ready from your positioning module with at least one movable Retaining element, which is mounted on the slider, wherein the retaining element with at least one arranged parallel to the guide rail stop rod corresponds.
- the Stop rod comprises shock absorber means, at least one end of Stop rod are arranged to the resulting when stopping the slider Absorbing impact stress.
- the holding element of the positioning module has a small-sized pneumatic cylinder with a fork-like end piece and the piston rod on.
- the holding element is capable of being formed with a threaded rod-like and with at least one nut provided as a stop element stop rod cooperate to form an adjustable stop for the positioning module.
- the shock absorber means comprises a shock absorber element which is arranged at least at one end of the stop rod and with one opposite arranged on the pneumatic cylinder stop element interacts.
- the shock absorber element can at least partially directly into the Stop rod integrated to save space.
- the pneumatic working unit according to Figure 1 comprises a rodless Pneumatic cylinder 1 with an outer slider 2, which on the cylinder 1 by a Guide rail 3 is guided with rolling elements.
- the guide rail 3 is with a (not shown) inner piston of the pneumatic cylinder 1 connected to the Slider 2 according to a mutual application of the inner piston to move.
- On slider 2 is a profile holder 4 for attachment of a Profile tube 5.
- the profile tube 5 transmits the pneumatically generated force to a Connection unit 6, which is arranged at the other end of the profile tube 5.
- a positioning module 7 is provided that two movable holding elements 8a and 8b.
- the positioning module 7 is on the slider 2 by several Screws detachably fastened.
- the holding elements 8a and 8b work with a Stop rod 9 together, parallel to the guide rail 3 on Pneumatic cylinder 1 is arranged.
- the pneumatic cylinder 1 comprises a adjustable shock-damped end stop element 10 for stopping the slider 2 when reaching one end position.
- the same end stop element (not shown) is also present from the other end position.
- the stop rod 9 has here two end-mounted shock absorber elements 11 a and 11 b, with corresponding mechanical stop elements 12a and 12b on the side of Pneumatic cylinder 1 cooperate to the stopping of the slider. 2 absorb occurring impact stresses.
- the shock absorber elements 11a and 11b are partially within the Stop rod 9 integrated.
- the stop rod 9 is on the pneumatic cylinder 1 through a holding profile 13 with two bearing elements 14 a and 14 b held such that a slight back and forth movement of the stop bar 9 is possible, so that the Can develop shock absorber effect.
- the holding elements 8a and 8b of the positioning module 7 comprise small-sized Pneumatic cylinder with a fork-like end 15 on the piston rod.
- the Stop rod 9 is formed as a threaded rod, with this Antschmuttem 16 are screwed to adjustable stops for the positioning module 7 to form.
