Clamping bolt with integrated RFID transponder

Abstract

An attachment for a clamping bolt has a base body and an opening which passes through the base body. Around the through-going opening runs a contact face which is positioned orthogonally on the longitudinal axis of the through-going opening and which is configured to make contact with the clamping bolt. A receptacle region runs around the through-going opening in the basic body, between the through-going opening and the contact face. An RFID transponder is arranged in the receptacle region. The clamping bolt has a circular-cylinder-shaped clamping region. A first boundary region and a second boundary region bound the clamping region along the longitudinal axis of the clamping bolt Each boundary region has a larger external diameter than the clamping region. The attachment is arranged on the first boundary region. A through-going opening runs along the longitudinal axis of the clamping bolt.

Description

[0001]The present invention relates to an attachment for a clamping bolt. A RFID transponder is arranged in the attachment. Furthermore, the present invention relates to a clamping bolt that has the attachment according to the invention.PRIOR ART[0002]Zero-point clamping systems are provided to fix carrier components, in particular workpiece carriers or clamping plates, exactly in a predetermined position with repeat accuracy. They are used, for example, when processing cylinder heads and crank housings. The zero-point clamping modules to be used thus generally provide a receiver in which a clamping bolt can be inserted. Furthermore, clamping means are provided which act against the clamping bolt in a radially internal position and fix this in the locking position. In a radially external position of the clamping means, the clamping bolt can be removed from the clamping module.[0003]The clamping bolt is usually equipped with a circular-cylindrically shaped base shape. A clamping regi...

AI Technical Summary

Benefits of technology

The invention is a clamping bolt with an RFID transponder attachment. The attachment has a receptacle region that can hold a long RFID antenna, which allows data to be read from greater distances. The attachment is designed to ensure secure and fixed connection to a clamping bolt through both the contact surface of the base body and the filling material in the receptacle region. The clamping bolt has a circular-cylindrically shaped clamping region and a through opening for connecting it to a carrier component. The RFID transponder in the attachment enables the identification of the clamping bolt independent of its location. The technical effects of the invention are facilitating the efficient and secure attachment of an RFID transponder to a clamping bolt and ensuring the identification of the clamping bolt regardless of its location.

Problems solved by technology

When using clamping systems, the problem arises that a clamping bolt cannot be identified independently of the position without changing the function of the clamping bolt.

An integration of a RFID transponder into the base body of a clamping bolt is not possible since this usually consists of an electrically conductive metal and thus would shield the radio waves.

Thus, an increased effort when mounting the clamping bolt would emerge.
