Definitions
- the invention is based on a method for producing a mechanical connection according to the preamble of claim 1.
- flare connections are known in which two workpieces are first inserted into one another in such a way that one workpiece is supported against a stop of the other and projects over this with an edge, the flanged edge.
- the connection is carried out by folding, flanging, the flanging edge onto the one workpiece, so that the workpieces are joined in a form-fitting manner.
- two workpieces are required and it is difficult to achieve a defined contour of the flanged edge.
- a flanged edge must often be present all the way around a workpiece.
- dovetail connections are also known, in which tolerances have to be kept very narrow.
- a head part and a recess of the dovetail connection are placed one above the other and then pressed into one another, as described in DE 39 25 365 AI.
- the parts must be there are placed one on top of the other and are not pushed into one another, so that the parts to be connected are designed to be somewhat longer and the tolerance, for example of an inner diameter of a tubular element, is greater.
- connection method for a metal strip in which a tongue is caulked into a depression.
- a voluminous tool and high forces are required to carry out the caulking.
- a snap connection which consists of a tongue and a recess.
- the tongue and the recess are pushed into each other to make a connection.
- the areas around the recess are designed to be elastic so that they can widen and spring back when the tongue and recess are pushed together.
- the method according to the invention for producing a mechanical connection with the characterizing features of claim 1 has the advantage that at least two sections of a workpiece are connected to one another in a simple manner and tolerances of the at least one workpiece do not have to be kept very closely.
- the method steps or measures listed in the dependent claims allow advantageous developments and improvements of the method mentioned in claim 1 for producing a mechanical connection and the connection thus produced.
- the connecting element has a centering element, because this makes assembly easier and / or centering is facilitated.
- An advantageous embodiment of the connecting element arises from the fact that there is no radial and or axial projection on the workpiece.
- the connecting element can be used advantageously for a tubular element if the tubular element is fastened to an inner part by the action of the connecting element and this inner part has two short guide lengths.
- FIG. 2a, b show a connecting element and an inner part with short guide lengths
- FIG. 3 shows a possibility of mounting the connecting element. Description of the embodiments
- FIG. 1 a shows a connecting element 1 which can connect a first workpiece 5 and, for example, a second workpiece 6 to one another.
- the two workpieces 5, 6 can also be sections of a workpiece 7, e.g. a tubular element 7 bent from a rectangular sheet metal strip.
- One end 10 of the first workpiece 5 and one end 11 of the second workpiece 6 correspond to a modified dovetail contour 14 and form the connecting element 1.
- the arrows 18 show, for example, the direction in which the ends 10, 11 are inserted into one another.
- the ends 10, 11 are pushed into one another, for example, until the ends 10, 11 touch and are supported against one another. However, this is not absolutely necessary.
- the workpieces 5, 6, 7 have a longitudinal or center line 16 which, for example, runs centrally through the centering element 24.
- the end 11 has a projection and the end 10 has a corresponding recess into which the projection is inserted with the least possible play, if, for example, centering is required.
- the workpiece 5, 7 and the workpiece 6, 7 each have outer boundary lines 64, 66, which are shown here in dashed lines, and which continue in a straight line beyond the ends 10, 11. Lines 64, 66 do not run approximately parallel to one another if the mechanical connection has not yet been established. If the ends 10, 11 or two workpieces 5, 6 are inserted into one another, then at least one existing edge 27 of a workpiece 6, which projects beyond the other workpiece 5, acts by means of a force F in a certain direction, which is indicated by the arrows 21 is curved.
- the dovetail-like contour 14 is formed, for example, at the end 10 by a head part 49, which is followed by a constricted neck section 53.
- the end 11 is provided with a depression 57, which is delimited, for example, on both sides by an edge 27.
- the free ends of the edges 27, which are pulled slightly outwards from the trough 57, are directed towards one another.
- Lugs 61 are provided, between which the head part 49 can be pushed into the trough 57.
- the lugs 61 have a contour such that they engage in the neck section 53 after the application of the force F.
- the centering element 24 is provided in the head part 49 or in the depression 57.
- FIG. 1b The workpieces 5, 6 connected to one another in accordance with the method according to the invention are shown in FIG. 1b.
- the ends 10, 11 are supported against one another in this exemplary embodiment.
- the connecting element 1 is, for example, designed such that there is no radial and / or no axial protrusion and the workpieces 5, 6 are connected to one another in a form-fitting manner.
- the boundary line 64, 66 now run approximately parallel to one another.
- the dovetail-like contour 14 is designed, for example, in such a way that tensile stress is exerted on the two workpieces 5, 6 in the circumferential direction when the edge 27 is bent.
- Figure 2a shows the tubular element 7 in the open state. In this state it has a larger inner diameter than the largest outer diameter of an inner part 30, so that the tubular element 7 can be pushed over the inner part 30.
- the tubular element 7 is guided by, for example, two radially projecting guide lengths 33 of the inner part 30.
- the connecting element 1 is closed, the tubular element 7 lies tightly against the guide lengths 33 and is thereby fastened on the inner part 30 (FIG. 2b).
- Figure 2b shows how the tubular element 7 is attached to the inner part 30.
- the inner part 30 has, for example, two short guide lengths 33. Briefly here means that a contact length in the axial direction of the tubular element 7 with the inner part 30 is significantly shorter than an axial length of the inner part 30. However, the contact length can also cover the entire axial length of the inner part 30 correspond.
- the inner part 30 is, for example, a coil body, for example for a stator of an electric motor, which has a coil space 38, in which, for example, a coil (not shown) is wound.
- the tubular element 7 forms, for example, a magnetic yoke element. In the case of a positive connection, the magnetic flux lines in the return element can run from end 10 to end 11 without great magnetic resistance.
- FIG. 3 shows how, for example, a tubular element 7 in the open state can be pushed over an inner part 30, which has areas with two different outer diameters dg and dk, in an insertion direction, indicated by an arrow 42.
- the diameter dg is larger than the diameter dk and the area with the outside diameter dk is surrounded by areas which have a larger outside diameter.
- the tubular element 7 can thus dk on the inner part 30 in the region of the smaller outer diameter are attached without the ends of the tubular element 7 having to be widened such that the distance between the ends (10, 11) corresponds to that of the outside diameter dk.
