Measuring device for a pipe-cutting machine

摘要

The invention relates to a measuring device for precisely determining the length of at least one longitudinal profile between two measuring arms opposite of one another, with said two measuring arms opposite of one another and a measuring stamp, which can be moved in one of the measuring arms by means of a linear guide. The longitudinal profile can be positioned such that one end abuts against the measuring stamp. The linear guide comprises a guide channel extending in a guiding direction and a guide element having an outer wall, which guide element can be moved back and forth in the guide channel along the guiding direction. The guide element comprises a first guide length and a first guide width and forms a first width/length ratio. On the outer wall, in a cross-section that is vertical to the guiding direction, indentations and/or protrusions are provided circumferentially in the guide section direction, each having an additional guide length, an additional guide width and an additional width/length ratio, wherein the additional width/length ratios are smaller than the first width/length ratio.

1. A measuring device for the precise determination of a length of at least one elongate profile between two mutually opposed measuring arms, and with the two mutually opposed measuring arms and a measuring stamp are movable by means of a linear guide within one of the measuring arms, wherein the at least one elongate profile is capable of being positioned for abutment with one end on the measuring stamp, characterized in that the linear guide has a guide channel formed in a guiding direction and a guide element with an outer wall which is movable in a reciprocating manner in the guide channel along the guiding direction, and the guide element has a first guide length and a first guide width and forms a first width/length ratio, and protrusions and/or indentations are provided on the outer wall in a cross-section at a right angle to the guiding direction and the protrusions and/or indentations are aligned in the guiding direction and the protrusions and/or indentations are each provided with one further guide length and one further guide width and with one further width/length ratio, and the further width/length ratios are smaller than the first width/length ratio.
