Definitions

  • the invention relates to a linear drive device, having a longitudinal extension having a base structure and a linearly displaceably mounted carriage, wherein the base structure has two in parallel alignment with transverse spacing alongside juxtaposed, incorporated as an independent components guide profile parts which are rigidly connected to each other by means of a separate intermediate structure arranged between them are and each carrying at least one longitudinal guide rail for slidably supporting the cross-gap bridging carriage, wherein the carriage is in driving connection with linear drive means, which are at least partially accommodated in a housing profile part of the base structure.
  • a linear drive device of this type known from DE 20 2006 013 135 U1 contains two guide profile parts which are parallel to one another and are rigidly connected to one another by an intermediate structure arranged between them.
  • the intermediate structure provides a transverse spacing of the guide profile parts, wherein the latter are each equipped with a guide rail and wherein on the two guide rails a cross-bridging bridging carriage is arranged.
  • the guide profile parts and the intermediate structure are each incorporated as independent components in the basic structure and fastened together by clamping devices.
  • At least one of the guide profile parts has a dual function in that it also acts as a housing profile part, which receives linear drive means, which are in drive connection with the carriage.
  • a disadvantage of this arrangement is that a symmetrical introduction of the driving forces in the carriage can only be realized if both guide profile parts are designed as housing profile parts equipped with linear drive means. Limit the linear drive means on one of the guide profile parts, there is an asymmetric force introduction, which can cause problems when high acceleration forces or when transporting heavy masses occur.
  • a linear drive device is also in the introductory part of DE 20 2006 013 135 U1 discussed.
  • the base structure here contains an integral U-shaped profile element, whose legs each carry a guide rail.
  • the carriage mounted on the guide rails is driven by a separate linear drive, which is fastened between the two legs on the transverse web of the U-shaped profile element.
  • the pressing plants used in the extrusion production of profile parts easily reach the limits of their processing capacity.
  • the at least one housing profile part is incorporated as an additional component in addition to the two guide profile parts independent component in the base structure and forms a parallel between the two guide profile parts extending supporting component of the intermediate structure, such that the guide profile parts without direct Connection with the interposition of the at least one housing profile part are fastened together.
  • linear drive device is used to realize the basic structure as in the case of DE 202006013135 U1 to independent guide profile parts, which are fastened together by an intermediate structure.
  • at least one equipped with the linear drive means housing profile part is designed as a component of the intermediate structure and therefore sits between the two guide profile parts. This facilitates the initiation of the thrust force on the carriage in the region lying between the two guide rails and, with a corresponding arrangement, in particular also promotes a symmetrical introduction of force.
  • the two guide profile parts not like the legs of the U-shaped profile element of DE 19840876 B4 are integrally connected to each other, but installed as separate components, wherein the at least one housing profile part acts as a supporting link between the guide profile parts.
  • the two guide profile parts can therefore be made prior to assembly of the base structure as individual components with smaller cross-sectional dimensions, as in the integral U-shaped profile element of DE 19840876 B4 the case is. In other words, it is possible to realize linear drive devices even large transverse dimensions by adding a plurality of smaller profile parts in cross-section.
  • the intermediate structure can have only a single housing profile part for linear drive means. This can then be attached directly to one or both flanking guide profile parts. If a larger transverse distance between the guide profile parts is desired, at least one extension profile part can be incorporated between the housing profile part and one or both guide profile parts if required. The more the guide profile parts are spaced from each other, the greater the transverse distance of the guide rails arranged thereon, so that the carriage is able to absorb higher tilting moments.
  • the intermediate structure can have a plurality of housing profile parts for linear drive means arranged alongside one another in parallel alignment. Particularly advantageous is an equipment of the intermediate structure with two such housing profile parts in order to realize a total of two linear drives within the linear drive device.
  • the plurality of housing profile parts can be attached to each other directly or with the interposition of at least one distribution profile part.
  • the guide profile parts respectively adjacent to the guide profile parts can be fastened either directly or with the interposition of at least one widening profile part on the relevant guide profile part.
  • a plurality of housing profile parts having different cross-sectional configurations may be present, which are equipped with mutually different types of linear drive means.
  • at least two linear drives from the group of toothed belt linear drive, fluid-actuated linear drive and linear motor can be combined within a linear drive device.
  • the linear drive device is to be equipped with only a single linear drive, a variable production can be achieved when assembling the basic structure by appropriate selection of one of these drive types.
  • the individual profile parts can be attached to each other in different ways. Particularly advantageous is a type of fastening is considered in which hook structures are formed on the profile parts, which engage with each other, to generate a positive fit. Adjacent areas of the adjacent profile parts can then be glued or welded, for example, or deformed the hook structures by rolling or other reshaping measures to obtain a firm connection. It seems particularly expedient mutual clamping of interlocking hook structures by applying a hardening mounting foam in jointly defined by several profile parts cavities, the foam provides the required clamping force due to its occurring during curing increase in volume.
