Definitions
- the present invention relates to a device for determining the position or measuring a hole according to the preamble of claim 1 and an attachment element according to the preamble of claim 6.
- a device for measuring distances on an object which is inserted into a hole in the object to be measured.
- the device consists of two separate parts, namely a shaft for fitting into the hole of the object, and a part which ends in a ball of a certain radius of curvature.
- This ball 1 can be positioned such that it serves as a reference point with respect to the center of the hole.
- a disadvantage of this device is that a measurement in inaccessible places, for example on a floor panel of a motor vehicle - 2 -
- Tool body is not possible with this device, since the device has no means for its accurate measurement fixation in the hole to be measured.
- connection points in particular points that cannot be measured directly, such as ball centers
- a device for measuring distances from connection points which consists of a main scale with longitudinally adjustable slide bodies and measuring members which can be displaced transversely to the main scale. This relatively large device is not suitable for measurements in inaccessible places.
- German utility model G 91 06 101 discloses a precision measuring stick, which allows a measurement of the diameter of the opening by inserting a mandrel into an opening.
- the exact position determination of the opening is not the subject of the teaching described in this document.
- the object of the invention is to provide a device with which a position determination or measurement of inaccessible holes or recesses of a component is also possible in a simple manner.
- a device is now created with which the exact position determination of holes or recesses, for example a body of a motor vehicle, can be carried out in a simple manner.
- the at least partial formation of the attachment element from a magnetic material enables simple and reliable fixing of the device according to the invention to a component, which makes it easier to carry out very precise measurements. Measurements in inaccessible places, for example the floor panel of a motor vehicle body, are also possible without any problems, since the invented device according to the invention can be inserted, for example, from below into a hole in the floor panel and can be fixed in the inserted position without further aids.
- the device according to the invention can be produced very inexpensively.
- the attachment element has an essentially hemispherical or partially spherical shell made of a non-magnetic, and an insert made of a magnetic material arranged inside the shell.
- a conventional magnetic flat gripper can be used as the insert, which can be fixed in a shell, for example made of aluminum, in a simple and positionally accurate manner.
- the mandrel can expediently be screwed to the attachment element. On the one hand, this enables precise positioning of the dome in the attachment element, but on the other hand it is also possible to detach the two parts from one another without labor, so that an attachment element can be used for a large number of mandrels.
- the mandrel has an upper part formed with a screw thread, which through the use of is feasible and screwable on the inside of the shell.
- the insert can initially be positioned and / or fixed in a precisely fitting manner in the shell, as a result of which the attachment part assembled in this way can be used in an adapter-like manner together with a large number of spikes.
- the mandrel can be fastened asymmetrically with respect to the attachment element. This can be done, for example, by milling off a part of the hemispherical shell that is like a segment of a circle and the corresponding part of the insert. This makes it possible to use the device according to the invention in the immediate vicinity of a bend or a radius.
- Fig. 2 is a side sectional view of the device according to Fig.l in the assembled state
- FIG. 3 shows a sectional side view of a further embodiment of the device according to the invention.
- Fig. 1 the individual components of the device according to the invention are shown in detail, and in Fig. 2 in the assembled state.
- a mandrel 1 can be passed through its central part la formed with a screw thread through a central passage of an insert 4 of an attachment element 2 and with one on the inside of an outer shell 3 of the attachment element 2 provided internal thread 13 screwed.
- the insert 4 can be arranged and fixed precisely in the shell 3, as can be seen in particular in FIG. 2.
- the lower edge 3a of the shell 3 is flush with the underside 4a of the insert 4.
- the beveled or chamfered edge 3a ensures that the attachment element 2 can be easily positioned by hand or removed from a surface of a component.
- the mandrel 1 is usually made of a metallic material.
- the shell 3 is made of a non-magnetic material, for example aluminum, and the insert 4 is made of a magnetic material. It would be conceivable to also produce the shell 3 from a magnetic material. Furthermore, the components 3, 4 could be formed in one piece.
- the attachment element 2 can be fastened in a simple and secure manner to a body part, for example a floor panel 5 as shown in FIG. 3.
- the mandrel 1 arranged in the attachment element 2 is inserted into a hole formed in the base plate 5, so that the underside 4a of the insert can rest flat on the base plate 5.
- Magnetic forces between insert 4 and base plate 5 ensure that attachment of attachment element 2 to the underside of base plate 5, as shown, is also possible in a simple manner.
- a partial or hemisphere surface, as given by the surface of the shell 3, can be measured in a simple manner known per se (usually with 5 probing processes), so that the center of a hole, into which the one with the shell 3 is operatively connected standing mandrel 1 is introduced can be determined.
- the fact that an attachment element 2 can be used in an adapter-like manner for a large number of mandrels 1 means that the measurement or adjustment effort is important when measuring, for example, a body which has holes of different sizes into which different mandrels 1 must be inserted - 6 -
- FIG. 3 also shows how, according to a special embodiment of the attachment element 2, it is possible to measure holes that are difficult to access in the vicinity of an edge 5a.
- a hole to be measured can easily be up to about 5 mm away from its desired position without having to interrupt a CNC series measurement sequence when measuring the attachment element with a collision.
- the method for measuring a spherical surface is always the same, so that the surface or the characteristic data of the attachment element 2 can or can always be mirrored (reused) during programming, so that a repeated measurement of the spherical surface is not necessary.
