Clamping pin for clamping a component with an internal bore, and for application to measuring purposes

The present invention relates to a pickup needle. for receiving at least one internally trained part, especially for metering purposes.

The gripper mandrel is known from CH 541 377 A. CH 541 377 A also describes a fundamental problem that occurs with such gripping mandrels, namely, elastic or even plastic deformation of the component during gripping. Not least for this reason, tufts are known in the state of the art where additional air references are provided in DE 28 05 881 A1. DE 4 i 0 07? Sub-DE, '102' 14 U and DE 20 2011 051 311 U1, that are generally not met at all, or only certain conditions are met for measuring technology requirements.

US2006 / 010471IA1 discloses a fitting pin in which the component is fixed in a single plane. The disadvantage of this is that the component has a displaced face of the fumtm mem'egc'cial "k" '. In the solution of l'S2OO5'O025SOOAl, the insert has a recess on the inner surface of the element to be fastened. This has the disadvantage that it can only be used with a special fastening element with an internal surface.

It is an object of the present invention to provide a clamping mandrel as described in be / cohe, whereby the parts in question are preformed, and in particular, so that they can be clamped accurately again. that this pin is a measurement cemkni ss a kalr ^ s * cg \ en

This object can generally be solved by a semiconductor pin having the features of claim 1 according to the invention. Preferred totabröc flours are these Jonahs, both of them, and the following explanation.

With the mdlcrcnddt verbatim points, the felaoai solution also excels in the use of the alal>> ai for a measuring needle, especially for capturing a component having an internal bore and measuring wtmalals attached to that component by means of a measuring device or measuring machine.

The receiving pin for holding a component having an internal bore according to the invention includes:

- àíáksar sheathing cylindrical body,

- a rain battery drain sleeve which is arranged in a fixed position on the base body and which, with its radial expansion (B), lies on two axial ends (E1, E2l) directly on the strange wall of the component to be clamped, and

- two moccasins which are displaceable on both sides of the clamping sleeve on the base body and which, pressed at their axial ends, extend the simultaneous air to the heat of the pond.

Preferably, a clamping mandrel according to the invention comprises two movable sleeves which are disposed axially on both sides of the clamping sleeve on: the base body, and: for clamping a part, opposite or opposite, and preferably synchronously, the clamping sleeve: they may be pressed against, or pressed against, their ends, which cause the clamping sleeve to expand at both axial ends simultaneously, radially *, and the component to fade away. In the case of the Ig dome, the two seals are the same (symmetrical tension j). The clamping pond is preferably held or secured by a pin or pin penetrating the body.

Many of my tooths are tired. mud> ck's manual fktent will be explained in more detail, particularly with reference to the examples of the circle shown in the figures. The mandrel according to the invention is particularly suitable for metering purposes and for metering applications, inter alia, for a component to be measured, which is repeatedly accurate, and for the check sxortócro. and, thanks to these siphoning forces, it allows you to hold the shape unchanged.

Components 200 in the two caliper planes E1 and E2 are independent of the radial clamping path and the coulter height of the clamping arms 133. it can be clamped with the same clamping force (the same clamping force, which is fundamentally different from the same clamping path principle). Thereby also differentiating its clamp in the two clamping planes E1 and E2. For example, if the first clamping force in the upper clamping plane E1 is reached, only the lower clamping sleeve E2 will be heated by the lower clamping screw E2 until the same clamping force (and forditx a) is applied there.

El and and. E2 bursting plane. the filtering force bed to be achieved is dimensioned so that the component 200 is reliably solid but cannot be formed either plastically or elastically. The hair horsepower to be achieved can be predetermined by the torque introduced by screwing in one of the 151/152: clamping screws (for example, in the range of 2 NmAO Hm). In Horn's way, the juice on the caliper sleeves 130 is achieved with relatively long souto arms 133 with a high compression height (in the radial direction as shown by arrows B) such that the pivoting member 100 is resiliently similar to other components (with different internal diameter diameters) ) Can be used for repeated precision or repeated precision clamping.
