Definitions

  • the present invention relates to a workbench useful for supporting one or more workpieces on which one or more operations are to be performed, such as for example welding, drilling, cutting, filing, polishing, etc.
  • the workbench of the present invention is mainly, although not exclusively, applicable in the metal fittings and ironwork field.
  • a table provided with a horizontal upper face which is perpendicularly extended in side skirts is currently used as a workbench in the metal fittings and ironwork field.
  • a drawback of this workbench in the form of a table is that the upper surface does not allow the workpieces to project from the lower part thereof unless they are supported outside the extension of the upper surface by means of supporting elements in the form of side extensions and the like.
  • Another drawback is that the upper surface prevents accessing the lower areas of the workpieces which are secured thereon, and although it is possible to access the lower areas of the workpieces which are secured outside the work surface by means of extensions, this is very uncomfortable because it forces adopting squatting positions.
  • the regularly distributed orifices on the upper surface and side skirts of the table determine rigid positions for the accessory elements and do not allow a continuous sliding for selecting the ideal position thereof.
  • Patent US-A-5131253 describes a workbench provided to support vehicle chassis and bodywork parts in order to repair them.
  • the workbench comprises a rectangular frame supporting a plurality of transverse bars which can slide along guide rails existing in the stringers of the frame and which can be fixed in desired positions by locking means.
  • Accessory elements comprising positioning elements and supporting elements can slide along guide rails formed in the transverse bars and can be fixed in desired positions by locking means.
  • a drawback of this workbench is that not all the bars forming it include guide rails, and those which have them only include one guide rail in one of their faces. This makes the workbench non-versatile when the workpieces to be secured are single or small-series parts that are very different from one another, as occurs in the metal fitting and ironwork field.
  • the present invention contributes to solving the previous and other drawbacks by providing a workbench for supporting workpieces which comprises a framework formed by a plurality of bars connected to one another, where said bars have longitudinal guide rails along which accessory elements can slide, which accessory elements are selected from supporting elements, positioning elements and gripping elements useful for supporting, positioning and/or gripping one or more workpieces.
  • Locking means are provided for locking said accessory elements in any position along said guide rails.
  • Each of the bars forming said framework has a plurality of longitudinal faces and at least one of said guide rails is arranged on at least three of said longitudinal faces.
  • the framework has the form of a quadrangular frame, generally rectangular or square, formed by four of the bars connected at their ends, although alternatively the framework could be formed by a different number of bars and could have any other form, including an open form, such as a U shape for example.
  • the bars forming the framework have a quadrangular cross-section, although other sections such as such as triangular, hexagonal, octagonal, etc. are not ruled out.
  • the framework it is advantageous for the framework to have the form of a square or rectangular frame formed by four bars with a square or rectangular cross-section, such that the four bars forming the framework have respective mutually parallel and preferably flush upper faces, respective mutually parallel and preferably flush lower faces, respective mutually perpendicular inner side faces and respective mutually perpendicular outer side faces.
  • the framework has a square or rectangular form formed by four bars with a square or rectangular cross-section, and each of the four bars has at least one guide rail on each of its upper, lower, inner side and outer side faces.
  • one or more of the bars forming the framework can have two parallel longitudinal guide rails on one or more of the longitudinal faces thereof.
  • the framework is supported such that it can pivot with respect to a horizontal rotation shaft connected to the framework and supported in a supporting structure, and can be fixed in any angular position with respect to said supporting structure by locking means.
  • the supporting structure can be formed by a mobile rack in which the mentioned horizontal rotation shaft with respect to which the framework rotates is supported, and a base supporting said mobile rack such that the latter can rotate with respect to a vertical shaft.
  • the aforementioned supporting elements which can be fixed to the framework using the guide rails and locking means, include auxiliary bars and rotating plates.
  • the auxiliary bars have in turn guide rails along which others supporting elements and/or positioning elements and/or gripping elements can slide and can be fixed by means of corresponding locking means.
  • the rotating plates have a fixed part which can be fixed in a desired position in the framework or in an auxiliary bar, and a mobile part which can rotate with respect to the fixed part and which can be fixed in a desired angular position by means of locking means.
  • the mobile part of the rotating plate can in turn support other supporting elements and/or positioning elements and/or gripping elements.
  • a linear graduated ruler associated with one or more of the guide rails and an angular graduated ruler can be arranged in the rotating plates.
  • linear and angular graduated rulers are usable as a reference for positioning other accessory elements.
  • the workbench of the present invention allows supporting one or more workpieces virtually in any position of the Cartesian space (x, y, z axes), above, below, inside and outside the framework and in its vicinity. Furthermore, by virtue of the capacity of the framework for rotating on two shafts, it is possible to place the framework in an enormous variety of positions to provide a comfortable and direct access to virtually any area of the secured workpieces without needing to adopt squatting or uncomfortable positions. Furthermore, the position of the framework can easily be changed to provide an easy access to different areas of one and the same workpiece without needing to loosen it and secure it again.
  • the bars forming the framework and the auxiliary bars are obtained from extruded aluminium profiles incorporating the guide rails in the form of longitudinal passages with an inlet slot narrower than a bottom channel, and slide elements and conventional locking means adapted to profiles of this type are used to fix the bars and accessory elements to one another.
  • the supporting structure is preferably also formed by bars obtained from extruded aluminium profiles of the same type, although alternatively the supporting structure can comprise a conventional table or the framework can be installed on any other preexisting supporting structure.
  • reference number 50 designates a workbench according to an embodiment of the present invention, which serves for supporting workpieces.
  • the workbench 50 comprises a framework 1 with a rectangular shape formed by four bars 2 connected to one another at their ends.
  • the framework 1 is supported such that it can pivot with respect to a horizontal rotation shaft A connected to the framework 1 and supported in a supporting structure 10, and can be fixed in any angular position with respect to said supporting structure 10 by locking means.
  • the mentioned bars 2 have a rectangular cross-section and have four faces perpendicular to one another; two opposite wide faces and two opposite narrow faces. Along each of the two wide faces there are two parallel longitudinal guide rails 3 and along each of the two narrow faces there is one longitudinal guide rail 3.
  • the bars 2 can have a square cross-section with a single guide rail 3 on each face, or they can even have other cross-sections with a different number of faces, although it is convenient for there to be at least one guide rail on at least three of said faces.
  • the four bars 2 have respective mutually parallel and flush upper faces 2a, respective mutually parallel and flush lower faces 2b, respective mutually perpendicular inner side faces 2c and respective mutually perpendicular outer side faces 2d, and at least one guide rail 3 is arranged along each of them.
  • Fig. 3 illustrates a known system for fixing the bars 2 to one another or for fixing other auxiliary bars to the bars 2 using the guide rails 3.
  • the bars 2 of Fig. 3 are obtained, for example, from extruded aluminium profiles and have a square cross-section with a guide rail 3 on each of their faces 2a, 2b, 2c, 2d.
  • Each guide rail 3 has the form of a longitudinal passage with an inlet slot 3a narrower than a bottom channel 3b.
  • the bar 2 further has a hollow core 16 and a transverse hole 17 into which a sleeve 18 is fixedly inserted, which sleeve in turn has a transverse hole 19 aligned with the hollow core 16 of the bar 2.
  • the mentioned sleeve 18 further has a threaded axial hole 20 in which there is coupled a conical tip screw 25 provided with a gripping head 26 configured to be gripped by means of a tool, such as a key with a hexagonal stem (not shown), to loosen or tighten the screw 25.
