Definitions

  • the invention relates to a receiving element useful, for example, as a centering pin or receiving pin for centering and receiving components, in particular a plurality of metal sheet parts or at least one metal sheet part having a threaded female element, and more particularly employable in association with welding tools, in particular pressure welding tools, apparatus or machines.
  • a receiving element is disclosed in WO 2004/069 468 A1, having a bolt that, in the area of its external surface, which is largely parallel to a longitudinal axis, includes at least two recesses with apertures. Arranged in these recesses are pins that comprise or contain wear-resistant material and that extend somewhat radially through said apertures and project over the external surface with a predefined overhang.
  • Such receiving elements can be introduced into bores of at least one component for fixing and/or aligning for subsequent machining. For instance, if two metal sheets are to be joined to one another by welding, these contain receiving bores that match one another and into which a receiving element of the type cited is subsequently introduced for centering and receiving the metal sheets.
  • a plurality of such receiving elements are usefully provided as production or assembly aids.
  • the receiving elements can also be employed as holding pins and/or guide pins in machines, systems, or machining systems for components, these being for instance automatic welding machines, punches, or presses.
  • Production of these previously known receiving elements requires a certain complexity because first the at least two lateral apertures must be added to the bolt, which normally comprises metal, and then the at least two pins, which comprise or contain sintered material, must be introduced into the apertures, whereby in a useful manner in a further machining step, the pins projecting outward from the bolt are machined such that the surface areas of the pins that overhang farthest radially are located on a common surface. Even without performing this latter method step, adding at least two apertures to the bolt and preparing and inserting the two aforesaid pins entails production complexity that is not insubstantial.
  • a receiving element is disclosed in JP 02 290 696 A that has a sleeve comprising a sintered material, through which a bolt, provided with a tip, passes.
  • the end of the bolt facing away from the tip is provided with a thread that engages in a threaded bore of an element provided with a male thread, the aforementioned sleeve being clamped axially between the bolt tip and the element.
  • the production of the cylindrical sleeve made of sintered material is quite complex in order to avoid radial play in terms of the bolt that passes through and conversely to avoid undesired radial compression and associated waste during production.
  • this receiving element also comprises at least three parts, specifically sleeve and bolt and the threaded element that has a male thread, and thus the various machining steps being disadvantageous especially during serial production of large numbers of units.
  • the underlying object of the invention is to further develop a receiving element with less structural complexity while avoiding the aforesaid disadvantages such that high dimensional stability and positioning accuracy are assured for a long service life.
  • the production of the receiving element should not require great complexity and/or material consumption, and should be economical to implement.
  • the receiving elements should especially be used in welding systems or devices, for example, for producing pressure welded joints.
  • the receiving element in accordance with the invention is characterized by a simple and functionally appropriate structure.
  • the bolt comprises wear-resistant sintered materials, preferably oxide ceramics or non-oxide ceramics, for example, Al 2 O 3 , ZrO 2 , or Si 3 N 4 , or mixtures thereof, and contains at a forward end thereof a recess in which a tip, comprising metal, advantageously, for example, steel or high-grade steel, engages and is attached at one end section.
  • a direct or immediate connection is provided between the tip, via an end section thereof, and the recess, advantageously embodied, for example, as a blind hole, provided in the bolt.
  • the recess which is preferably coaxial with the longitudinal axis and/or penetrated thereby, permits a lasting and loadable connection in the comparatively short axially forward area of the bolt without a reduction in the cross-section of the bolt, whish is made of the high-performance ceramics or sintered material used, being necessary over the entire axial length.
  • the interiorly situated forward connecting area extends only over a fraction (portion) of the entire length of the bolt, advantageously less than 50%, and more preferably less than 30% thereof.
  • the end section of the tip and/or the forward connecting area possesses an axial length that is substantially smaller than the total length of the bolt. Furthermore, it is particularly important that the interiorly situated connecting area is reliably protected from attack by an environmental medium, for example, steam or aggressive gases.
  • the fastening of the tip or its end section in the axial recess of the bolt is advantageously embodied as an adhesive joint, shrink fit, press fit or clamp connection.
  • Mechanical processing for example, circular grinding, is used to grind the exterior surface of the bolt embodied from sintered material and/or high-performance ceramics to the required aperture diameter for the component to be processed, in particular metal sheet or threaded female element.
  • the metal tip prevents the extremely disadvantageous breakage with a high degree of functional assuredness.
  • components encountered in connection with the invention, in particular metal sheets can be readily joined to one another using the suggested receiving elements, in particular in welding tools and/or pressure welding tools, even with threaded female elements that are quite small, in particular with M4, M5, M6, or M8 female threads, avoiding failure times and idle times for the welding tools or automatic welding systems and attaining long useful life periods.
  • the bolt is advantageously produced, for example, by dry pressing, extrusion, or in an injection molding process and/or by mechanical processing.
  • the bolt is advantageously embodied as a part, either as tube or bar, and is provided and/or fitted with the metal tip at the forward free end.
  • a fastening body made of an insulating material advantageously, for example, plastic
  • an adhesive joint, shrink fit, press fit, or clamp connection preferably being provided.
  • the inventive receiving element is characterized primarily by the following improved properties: specifically, high wear-resistance and/or extremely long service life and/or good dimensional stability and/or precise positioning accuracy and/or high surface quality and/or optimized electrical insulation.
  • FIG. 1 is a schematic depiction of an axial section of a first exemplary embodiment according to the invention.
  • FIG. 2 is an axial section of another exemplary embodiment according to the invention having a fastening body made of an insulating material for additional insulation.
  • a receiving element comprises a bolt 2 , and a tip 4 that is produced as a separate component having an end section 6 which engages in a recess 8 of the bolt 2 at a forward end of the latter.
  • the bolt 2 comprises or contains wear-resistant sintered material, preferably oxide ceramics, such as, for example, Al 2 O 3 or ZrO 2 , or non-oxide ceramics such as Si 3 N 4 , or mixtures thereof.
  • the forward section 10 of the pin 4 projects axially out of the bolt 2 and presents an exterior surface 12 that is at least approximately and/or largely conical.
  • the tip 4 or the forward section 10 thereof includes a maximum external diameter 14 that is smaller by a prescribed amount than the external diameter 16 of the bolt 2 or the exterior surface 18 thereof.
  • the recess 8 in the forward end of the bolt 2 is preferably embodied as a blind hole, and the end section 6 extends axially over only a fraction of the entire length of the bolt 2 .
  • the exterior surface 18 runs largely parallel to the longitudinal axis 20 of the bolt or the entire receiving element and is advantageously embodied as a cylindrical exterior surface that is coaxial with the longitudinal axis 20 .
  • the exterior surface 18 can have a polygonal exterior contour.
  • a transition area 22 that tapers toward the end section 6 is present between the forward, advantageously conical, end section 6 and the exterior surface 18 of the bolt 2 .
  • the transition area 22 is usefully a component of the bolt 2
  • the transition area 22 can alternatively also be a component of the tip 4 .
  • the receiving element includes a stepped exterior contour with the forward section 10 of the tip 4 projecting out of the bolt 2 , the maximum external diameter 14 being substantially smaller than the external diameter 16 of the bolt.
  • the transition area 22 presents a substantially smaller axial extension than the end section 6 .
  • the takeout angle or cone angle of the transition area 22 is preferably substantially larger than the takeout angle or cone angle of the end section 6 .
  • the tip 4 comprises metal, advantageously steel or high-quality steel, so that, even when the external diameters of the receiving element and the bolt 2 are quite small, the tip 4 will not be damaged or broken off and/or a long service life or useful life is attained for the receiving element.
  • the direct connection of the tip 4 or the end section 6 thereof in the correspondingly embodied recess 8 is provided as an adhesive joint, shrink fit, press fit, or clamp connection.
  • the recess 8 is advantageously coaxial with the longitudinal axis 20 .
  • a step 24 is present between the axially projecting forward section 4 and the end section 6 arranged in the recess 8 , such that the maximum external diameter 14 of the forward section 10 is larger by a prescribed amount than the external diameter 26 of the end section 6 .
  • the step 24 thus forms a defined stop, in particular during insertion and/or when producing the connection between the bolt 2 and the tip 4 , which provides exact axial positioning and ultimately a defined axial length of the entire receiving element. Moreover, impermissibly high loading or even destruction of the connection between the tip 4 and the bolt 2 is avoided by virtue of the step 24 .
  • the bolt 2 contains a fastening body 30 at an end facing away from the tip 4 for placing the receiving element in a tool, for example, a pressure welding tool.
  • the fastening body 30 contains a flange, advantageously embodied as a radial extension for placement in the tool.
  • the receiving element is preferably embodied as a centering pin or receiving pin, and is used for centering and receiving components, in particular a plurality of metal sheet parts or at least one metal sheet part having a threaded female element.
  • the receiving element is provided primarily for employment and/or use in welding tools, in particular pressure welding tools or apparatus or machines.
  • the inventive receiving element is characterized by relatively small external dimensions.
  • the external diameter 16 of the bolt 2 is largely in the range of 3 to 12 mm, preferably 3.5 to 10 mm, and in particular from 4 to 8.5 mm.
  • inventive receiving element even very small threaded female elements having internal diameters of M4 or M5 or M6 or M8 threads can be centered by means of the receiving element or received thereby and in associated machines or tools, such as, for example, pressure welding machines, can be joined to metal sheet parts, whereby even with such small radial dimensions, the tip is prevented with certainty from breaking off due to the suggested embodiment of the metal tip 4 and its integration into the bolt 2 made of high-performance ceramics and/or wear-resistant sintered material and ultimately high functional security and/or service life is attained.
  • FIG. 2 illustrates another exemplary embodiment, according to which the fastening body 30 is not an integral component of the bolt 2 but rather is joined to the bolt 2 as a separate component.
  • the fastening body 30 comprises a special electrically insulating material, for example, plastic, in order to assure additional and/or improved electrical insulation of the receiving element with respect to the tool, in particular a pressure welding tool.
  • the bolt 2 contains a second recess 32 in which a connecting section 34 of the fastening section 30 engages.
  • the connecting section 34 is joined in the second recess 32 by an adhesive joint, shrink fit, press fit or clamp connection.
  • the fastening body contains a radial expansion and/or a flange 36 , the external diameter of which is greater than the external diameter of the bolt 2 .
  • a step is present between the connecting section 34 and the flange 36 , which serves to provide defined placement and/or axial alignment of the fastening body 30 with respect to the bolt 2 .
  • the bolt 2 contains a massive intermediate area 38 that assures high stability and/or strength of the bolt 2 and thus of the entire receiving element.
  • the bolt 2 can have a single central recess that extends across the entire axial length. If, corresponding to FIG. 2 , a separate fastening body 30 is provided at the back end, however, there is no immediate axial connection between the tip 4 arranged at the forward end and the fastening body 30 and consequently axial connecting forces between the tip 4 and the fastening body 30 are avoided in an advantageous manner. It is hereby also further stated that an interiorly situated recess can extend axially through the entire length of the bolt, including the integrally formed connecting body thereof, as well, alternatively to the embodiment in accordance with FIG. 1 . However, the connecting area in such an embodiment is provided solely on the forward end of the bolt 2 .
