Abstract

Rešenie sa týká zariadenia na merania drsnosti povrchu na pohybujúcich sa predmetoch a obzvlášť sa uplatní pri brúsení a inom obrábaní. Základným funkčným prvkom sú meracie hroty, nesúce kotvy pevne spojené rámom a radiálně pohyblivo uložené v kotúči otočnom okolo nepohyblivej osky, v ktorej sú upevněné indukčně cievky. Pri meraní sa otočný kotúč opiera o povrch pohybujúceho sa predmetu a jeho rotáciou prichádzajú meracie hroty do styku s nerovnosťou povrchu. Tým dochádza k změnám indukčnosti oievok, čo sa pomocou Wheastonovho mostíka a dalších zariadení spracuje na vhodné Statistické charakteristiky drsnosti povrchuThe solution concerns a device for measuring surface roughness on moving objects and is particularly applicable in grinding and other machining. The basic functional element is the measuring tips, carrying anchors firmly connected by a frame and radially movably mounted in a disk rotating around a fixed axis, in which induction coils are mounted. During measurement, the rotating disk rests on the surface of the moving object and its rotation brings the measuring tips into contact with the unevenness of the surface. This causes changes in the inductance of the coils, which is processed into suitable statistical characteristics of the surface roughness using a Wheastone bridge and other devices.

Description

Vynález se týká zariadenia na meranie drsnosti povrchu na pohybujúcich sa predmetoch a obzvlášť sa uplatni pri brúsení a inom obrábaní.The invention relates to a device for measuring the surface roughness of moving objects and in particular to grinding and other machining operations.

Doteraz sa zariadenie na meranie drsnosti povrchu pohybujúcich sa objektov bežne nepouží vajú. Známe sú však riešenia využívajúce odrazené lúče světla alebo dotykové meracie hroty pósobiace v otočných kotúčoch na indukčně cievky.·Until now, a surface roughness measuring device for moving objects is not commonly used. However, there are known solutions using reflected beams of light or tactile measuring tips acting in rotating discs on induction coils.

Nevýhodou světelných otočných lúčov je zachytávanie nečistót povrvhu a nevýhodou dotykových meracích hrotov a indukčných cievok je nutnosť používať zberné ústrojenstvá, t. j. kolektor a kefky.The disadvantage of the light rotating rays is the capture of surface contaminants and the disadvantage of the contact measuring tips and induction coils is the necessity to use collecting devices, i. j. collector and brushes.

Uvedené nevýhody nemá zariadenie na meranie drsnosti povrchu na pohybujúcich sa predmetoch ktorého podstatou je, že pozostáva z meracích hrotov, nesúoioh kotvy, kde meracie hroty sú spojené rámom a radiálně pohyblivo uložené v kotúči, ktorý je otočné uložený na oske s nepohyblivo upevněnými indukčnými oievkami.The aforementioned drawbacks have no device for measuring the surface roughness on moving objects, which consists in that it consists of measuring spikes, not anchoring the anchor, where the measuring spikes are connected by a frame and radially movably mounted in a disc rotatably mounted on an axle with immovably fixed induction loops.

Výhodou zariadenia podlá predmetu vynálezu je, že nepotřebuje zberný kolektor a kefky.An advantage of the device according to the invention is that it does not need a collector and brushes.

Na pripojenom výkrese, obr. 1 je schematicky znázorněný priečny rez. zariadením podlá vynálezu.In the attached drawing, FIG. 1 is a schematic cross-sectional view. device according to the invention.

Obr. 2 znázorňuje schematický rez v pozdlžnom smere.Fig. 2 shows a schematic section in the longitudinal direction.

Zariadenie ako je znázorněné na pripojenom výkrese, podlá obr. 1 a obr. 2 pozostáva z meracích hrotov 2, nesúcioh kotvy 2, Ρθνηε spojených rámom 2 a radiálně pohyblivo uložených v kotúči £, ktorý je otočné uložený na oske 5 s nepohyblivo upevněnými indukčnými cievkami 2·The device as shown in the attached drawing, according to FIG. 1 and FIG. 2 consists of the measuring tips 2 carrying the armature 2 connected to the frame 2 and radially movably mounted in the disk 6, which is rotatably mounted on an axle 5 with immovably fixed induction coils 2;

Pri meraní sa kotúč 2 umiestnený na oske 2 opiera o povrch nezakresleného pohybujúceho sa predmetu, čím začne rotovat a meracie hroty 2 nesúce kotvy 2, spojené rámom 2 prichádza striedavo do styku s nerovnosťami povrchu. Tým dochádza k změnám vzduchových medzier medzi kotvami 2 a cievkami 2 a tým aj k změnám indukčnosti, čo sa pomocou v obrazooh nezakresleného Wheastonovho mostika a dalších zariadení spracuje na vhodné štatistické charakteristiky drsnosti povrchu.During measurement, the disc 2 located on the axle 2 rests on the surface of an unmoved moving object, thereby starting to rotate and the measuring tips 2 carrying the anchors 2 connected by the frame 2 come in contact with surface irregularities alternately. This changes the air gaps between the anchors 2 and the coils 2 and hence changes the inductance, which is processed into suitable statistical characteristics of the surface roughness by means of a not illustrated Wheaston bridge and other devices.
