Definitions

  • the invention relates to a linear drive device with heavy-load guiding means, with a guide structure having two longitudinally spaced along parallel alignment with longitudinal members, which are combined by a cross between them existing bridging connection means to form a rigid assembly and each carrying a longitudinal guide rail, with a the two guide rails linearly displaceably mounted lifting carriage and with at least one along the stroke of the lifting rod extending rodless linear drive, the output member is drivingly coupled to the lifting.
  • Linear drive devices of this type are used in particular when relatively heavy components are to be displaced linearly and / or positioned, wherein they can also be used to construct multi-axis systems.
  • a linear drive device of the type mentioned is known, which has two guide rails each carrying a longitudinal rails, which are an integral part of a U-shaped profile element. On the guide rails is a the space between the two longitudinal beams bridging Hubschlitten slidably mounted.
  • Another advantage is that through the integration of linear drive and longitudinal beam an automatic parallel alignment of guide means and drive means takes place, which simplifies the assembly of the linear drive device and still combines high precision with low susceptibility to wear during operation.
  • An identically designed housing part can also be used in a longitudinal beam not designed as a linear drive, it being possible in this case to dispense with the output member in order to save costs.
  • the use of identical parts for the guide rail-bearing component proves to be a further advantage.
  • the preparation of a specifically designed, serving only for guiding purposes component can therefore be dispensed with.
  • the guide rails are expediently arranged in the same direction and in this case by a longitudinal plane extending away from the main longitudinal plane extending between the two longitudinal members.
  • the drive-like coupling between a respective output member and the lifting takes place expediently in the region of the opposite of the guide rail of the other longitudinal spar longitudinal side of the respective associated guide rail.
  • the fixing of the at least one connecting body is expediently exclusively by clamping on each longitudinal spar. An immediate screw connection is therefore unnecessary. This also simplifies fine adjustments of the individual components relative to each other during assembly of the linear drive device.
  • a particularly compact arrangement results when the at least one connecting body is accommodated in its entirety within the intermediate space between the two longitudinal beams. It then protrudes disturbingly at neither of the two open sides of the gap. In particular, it can terminate flush with one of the two open sides of the intermediate space with the adjacent outer surfaces of the longitudinal members lying there.
  • At least one of the connecting bodies may be penetrated in its longitudinal direction by at least one cavity opening out to its two end faces.
  • This cavity can serve alone to save weight, but it can also fulfill an additional function, for example, to guide a Fluids or for receiving electrical and / or fluidic conduit means.
  • the guide structure 2 comprises two parallel longitudinally spaced adjacent longitudinal beams 7, which are aligned parallel to the main axis 4. They have the same length among each other.
  • the two longitudinal bars 7 extend in a direction indicated in Figures 2 and 4 main plane 8, which is spanned by the main axis 4 and a perpendicular transverse axis 12 of the guide structure 2.
  • the connecting device 14 By accommodating the connecting device 14 in the intermediate space 13, it is achieved, inter alia, that the connecting device 14 does not act or only insignificantly on the height of the guide structure 2, which is measured in the direction of a vertical axis 11 perpendicular to the main plane 8.
  • the rodless linear actuators 6 are designed in fluid-actuated design, in which they are operated in particular with compressed air.
  • the output member 29 is formed as a longitudinally of the receiving space 28 displaceable piston, which axially subdivides the receiving space 28 in two Beauftschungshuntn said so via control channels 32 in a coordinated manner can be acted upon with a pressure medium, that the output member 29 is driven to the working movement 3.
  • At least one rodless linear drive 6 could also be designed as an electric linear drive.
  • the output member 29 may be penetrated by a threaded hole with which it is on a is electrically driven to a rotational movement driven threaded spindle whose rotational motion is converted into a linear movement of the output member 29, which in turn is transferable via a driver member 33 or by magnetic coupling to the lifting carriage 5.
  • the tubular body 24 is, in particular, a profiled extruded part which, for example, made of aluminum material, can be manufactured very inexpensively.
  • the connecting devices 14 of both exemplary embodiments have in common that they each have at least one connecting body 38 arranged in the intermediate space 13 and bridging this intermediate space 13, which is fastened to both longitudinal bars 7 in such a way that a rigid assembly is defined by these components.
  • the two embodiments differ in the number of connecting bodies 38 used.
  • the connecting device 14 is designed to allow in a detachable manner a purely clamping attachment of the connecting body 38 at the respectively associated longitudinal beam 7.
  • each clamping device 44 expediently contains a manually actuatable actuator 48, possibly using a tool.
  • This actuator is designed in particular as an adjusting screw mounted in the connecting body 38.
  • each clamping device 44 includes a fixed and preferably integrally arranged on the connecting body 38 fixed retaining claw 45 which faces in the direction of the vertical axis 11 a relative to the connecting body 38 movable retaining claw 46 which cooperates with the actuator 48.
  • the connecting body 38 can thus be hooked with its two fixed retaining claws 45 in the terminal block 43, to then actuate the movable holding claw 46 by actuation of the actuator 48 and to fix.
  • the clamping movement of the movable holding claw 46 is a linear movement, in the axial direction of the vertical axis 11.
  • the clamping movement of the movable retaining claw 46 is a pivoting movement.
  • the actuator 48 acts on a transmission lever 52, which causes the pivotal movement of the movable holding claw 46.
  • mounting plates 54 may be attached as needed, which can be used as interface elements and / or as an adapter for attaching the guide structure 2 to a support structure, such as a machine frame are.
