Definitions
- the invention relates to a fastening device referred to in the preamble of claim 1 Art.
- a generic fastening device is known from DE 10 2006 050 640 AI, Fig. 4B known.
- the support member in this case has a groove formed in the surface, which is formed on one side by a flanged flange.
- the clamping screw is integrally formed, which is secured to the plate formed as a base body after passing through a hole with a nut and tensioned. Regardless of the tension of the clamping screw is in accordance with the principles of this document, which is particularly explained in Fig. 5, ensure that the plate is held in the groove with play.
- the object of the present invention is to keep the plate safely and without play on the fastening device in a generic fastening device.
- the support member is elastically deformable such that during clamping, the groove width is reduced.
- the term groove referred to in the context of this application also provided in a two-part support member paragraph which defines a gap passing through the hole.
- the support of the plate in a groove of the support member provides on the one hand the advantage of a captive attachment of the fastening device to the plate and further has the advantage that the plate is held at a distance from the main body. It is at this point so avoided by close contact of the plate formed on the body narrow gap, which can lead to corrosion and hygiene deficiencies.
- the clamping screw may for example be arranged laterally next to the support member, but this runs through advantageous according to claim 2, so that a central, all-round uniform stress on the groove is exercisable, which leads to a uniform tensioning result.
- the clamping screw can be secured for example on the base body by means of a nut, but is preferably screwed according to claim 3 in a threaded bore, which simplifies the assembly.
- the elastic yielding of the support member for clamping the groove is preferably provided according to claim 4, characterized in that the clamping screw rests against the support member in an edge region of the groove. Therefore, the clamping force is exerted mainly on the outer edge region of the groove, where it is better compressible, especially if there is a firm connection to the groove base.
- the support member may be made in one piece, but is preferably made according to claim 5 of two parts, which not only facilitates the production of the complicated part, but also is used to easier to arrange the support member to the hole of the plate can, if it is in two parts is attached to both sides of the hole and then when through the hole, the two parts are joined together, resulting in a captive attachment of the tendon on the plate.
- the support member may for example be formed star-shaped or rectangular, as suggested in the document mentioned above, but is preferably formed rotationally symmetrical to the clamping screw. This results in an all-round uniform tension of the groove and a particularly easy to manufacture construction.
- the hole in the plate is preferably designed according to claim 8 as a slot in which the fastening device in unstressed condition ver ⁇ is slidable to give a certain adjustment between the plate and the fastening device.
- FIG. 1 the invention is shown for example and schematically in a single FIG. 1 with an axial section through a fastening device according to the invention.
- Fig. 1 shows a base body 1, which is formed for example by a housing wall of a machine to which a plate 2 is to be attached. This is done by a fastening device 3.
- the fastening device 3 has a clamping screw 4. This has on the end portion of a shaft 5, an external thread 6 and at the other end of the shaft 5 a polygonal screw head 7. To accommodate the screw 4 is provided with an internal thread 8 threaded hole 9 in the base body 1.
- the clamping screw 4 passes through its shaft 5 a bore 1 1 of a supporting member 12 which is formed in the embodiment rotationally symmetrical to the clamping screw 4 and consists of two pieces of a sleeve 13 and a ring 14, which are fastened to each other for use.
- the support member 12 is secured with a circumferential groove 15 on the plate 2 and that in a slot 16 of the plate 2.
- the support member 12 in two-part state, ie with its separate parts and 14, attached to both sides of the elongated hole 16 until, in the position shown in Fig. 1, a base body 1 lying towards end face 17 of the sleeve 13 rests against the plate 2 and on the end face 17 in the direction of the base body 1 toward multi-projecting Sleeve piece 18, the slot 16 extends through.
- the ring 14 is placed on a shoulder 20 until the abutment of its end face 17 opposite the counter surface 19.
- the sleeve piece 18 is crimped in its end region, as shown in FIG. 1, at right angles to the inner edge region of the ring 14, so that the ring 14 on the sleeve 13 between the bent end portion of the sleeve piece 18 and the sleeve piece 18 radially projecting heel 20 is firmly clamped.
- the dimensions of the groove 15 are matched to the plate 2, that the width B of the groove 15 between the end face 17 of the sleeve 13 and the counter surface 19 of the ring 14 is equal to or slightly larger than the thickness of the plate 2. This is the easiest as shown by the axial distance of the shoulder 20 set by the end face 17.
- the ring 14 projects in its outer edge region 21 with respect to its inner regions in the direction of the main body 1 back in such a way that the edge region 21 in the direction of the clamping screw 4 is closer to the base body 1, as lying to the base surface of the bent portion of the Sleeve piece 18.
- the bore 1 1 in the sleeve 13 has a short internal threaded piece 22.
- the support member 12 is first secured in the slot 16 of the plate 2 in the manner described above by connecting the two parts 13 and 14 captive.
- the clamping screw 4 is arranged in the described manner in the support member 12.
- the plate 2 is attached to the support member 12 at the location of the threaded hole 9 provided there and it is tightened the clamping screw 4 with its external thread 6 in the threaded hole 9, in the manner shown in Fig. 1, the support member 12 with the Edge region 21 of the ring 14 rests on the surface of the base body 1.
- the plate 2 is initially slidably seated in the groove 15, since the width B of the groove 15 is equal to or greater than the thickness of the plate 2. So it can now the position of the plate 2 to the position of the threaded hole 9 through Moving the support member 12 are adjusted in the slot 16.
- the slot 16 is to be dimensioned such that it is greater in its length than the groove 15 to allow a displacement of the support member 12 relative to the plate 2. In the width, perpendicular to the plane, however, in the illustrated construction, the slot 16 must be narrower than the outer diameter of the ring 14 and the sleeve 13, so that the slot 16 is seated with edge regions in the groove 15.
- this is achieved in particular by the fact that the ring 14 abuts the base body 1 only in its edge region 21 and thus the tensioning forces passing through the support member 12 act in the outer edge region of the groove 15.
- the ring 14 By elastic deformation of the ring 14 in its outer region results in a good clamping action on the plate 2, although the ring 14 is supported in its radially inner region on the shoulder 20.
- the ring 14 is made of suitable elastically deformable material, for. B. a suitable steel and springs back after loosening the tension of the clamping screw 4, so that then the clamping member 12 is freely displaceable again in the slot 16.
- the entire support member 12 is rotationally symmetrical to the bore 1 1 is formed.
- it can be chosen a rectangular basic shape, especially if twisting of the support member 12 is to be prevented in the slot 16.
- the attachment of the ring 14 to the sleeve 13 is given by bending the sleeve piece 18 in the illustrated embodiment.
- the ring 14 can also be fastened in a manner not shown otherwise on the sleeve 13, for example by welding.
- a round hole can be used in the plate 2.
- a smooth hole with a nut for clamping the clamping screw 4 may be provided.
- the ring 14 at the bottom of the groove 15 by crimping firmly connected to the sleeve 13, here also a loose connection can be selected.
- the sleeve piece 18 should not be flanged, so run cylindrically.
- the ring 14 sits loosely on it. Hereby can be stretched exactly as with the construction shown in Fig. 1. However, the parts 13 and 14 could fall apart as soon as the clamping screw 4 is released.
- the captive mounting of the fastening device 3 on the plate 2 would now be absent, but can easily be replaced by alternative constructions.
- This task of securing the ring 14 to the sleeve 13 may be e.g. be taken over by the clamping screw 4.
- the inner threaded piece 22 could be omitted in the sleeve 13 and arranged in the ring 14.
- the distance between the external thread 6 and the screw head 7 of the clamping screw 4 could be chosen so that the screwed through the provided in the ring inner threaded piece external thread 6 holds the ring 14 and the sleeve 13 captive.
- the securing of the screw on the support member then takes place via another component which has the shape of a disk with internal thread.
- the exterior diameter of the disc is less than the inner diameter of the support member, so that you can screw the component on the thread of the screw and the component is then arranged loosely on a thread-free portion of the screw in the support member movable.
