Problems solved by technology

The wiper strips of such wiper devices can here have complex geometries, in particular polygonal boundaries with several straight wiper strip sections, so that it is difficult to keep a close eye on the exact state of wear of each wiper strip section

Embodiment Construction

[0028] first reference figure 1 a and 1 b describe a first embodiment of a wiper 14 according to the invention, in which a signal line 18 in the form of an electrical conductor 20 with two conductor parts 30 is used as the wear indicating device 10 . The wiper 14 here includes a wiper strip 16 which is fastened to a carrier 28 of the wiper 14 . The wiping strip 16 and the support 28 here have a substantially straight, i.e. unbent, longitudinal extension and run parallel to the surface of the machine tool to be cleaned, which is not shown here and is not shown here for the sake of clarity, wiping Strip 16 contacts the surface to be cleaned. In order to remove, for example, impurities deposited on the surface to be cleaned, such as chips or other contaminants produced during metalworking, the wiper 14 is moved linearly along the surface to be cleaned, perpendicular to its longitudinal extension. As the wiper strip 16 contacts the surface to be cleaned under preload in the proc...

Abstract

The present invention relates to a scraper (14) for scraping a surface of a machine tool having a wear-indicating device (18, 20, 24, 30) for the scraper lip (16) of the scraper. At least one signal line (18) is embedded in the scraper lip (16) in such a manner that, upon reaching the wear limit (G), at least one section of the signal line (18) is exposed.

Description

technical field [0001] The invention relates to a way wiper for cleaning machine tool surfaces, having a wear indicating device for a wiper strip of the wiper. Background technique [0002] For example, wiper units are used in modern machine tools to clean the coolant / lubricant at the bellows or flap cover of the respective machine. By means of such a wiper device, also referred to herein as a wiper, the guide rails of such machine tools are likewise freed of impurities deposited thereon, such as chips or other contaminants from metalworking, in order to prevent premature wear of the guide rails. As the wiper strips of such wiper devices come into contact with the rail under preload, the wiper strips are subject to substantial wear and must therefore be replaced from time to time. The wiper strips of such wiper devices can have complex geometries here, in particular polygonal boundaries with several straight wiper strip sections, so that it is difficult to keep a close eye ...
