(54) Zariadenie na nastavovanie priečnych úvratí a odčítavanie velkosti automaticš kého priečneho posuvu saní brúsky(54) Device for adjusting transverse dead centers and reading the size of the automatic transverse displacement of the grinding carriage

Vynález sa týká zariadenia na nastavovaní^ s priečnych úvratí a odčítavanie velkosti automatic··] kého priečneho posuvu saní, vhodné použiť u ró-i vinných brúsok. Zariadenie slúži na určenie poloh, v ktorých dochádza k reverzácii priečnych saní, na stanovenie velkosti dráhy priečnych saní a na odčítanie skutočnej hodnoty automatického přerušovaného posuvu priečnych saní vodorovných rovinných brúsok.BACKGROUND OF THE INVENTION The present invention relates to a device for adjusting the transverse dead center and for reading the size of the automatic transverse displacement of the carriage, suitable for use in the case of wine grinders. The device serves to determine the positions in which the transverse carriage reverses, to determine the size of the transverse carriage path and to read the actual value of the automatic intermittent displacement of the transverse carriage of horizontal plane grinders.

U rovinných vodorovných brúsok v súčasnosti vyrábaných sa priečne úvrate nastavujú buď narážkami, umiestnenými priamo na priečnych saniach, alebo pomocou nastavovacích bubienkov na prednej stene predného lóžka, ktorými sa ovládajú ί rotačně narážky poháňané odmeriavacou týčou. Nevýhoda prvého, riešenia je, že neposkytuje možnost odčítavania hodnoty automatického priečneho posuvu, nastavovanie úvratí je nepohodlné a u brúsok riešených s posuvným stojanom je z hladiska obsluhy naprosto nevyhovujúce. Nevýhodou druhého riešenia je malá presnosť nastavenia úvratí a možnost' len hrubého odčíťania velkosti automatického priečneho posuvu. U obidvoch riešení je třeba nastavovat’ obidve úvrate samostatné, pričom určenie velkosti dráhy priečneho posuvu je nepohodlné jIn the plane horizontal grinders currently produced, the transverse dead center is adjusted either by means of stops placed directly on the transverse carriage or by means of adjusting drums on the front wall of the front bed, which control the rotational stops driven by the metering rod. The disadvantage of the first solution is that it does not provide the possibility of reading the value of automatic transverse feed, setting dead center is inconvenient and for grinders with a sliding stand is absolutely unsatisfactory from the operator's point of view. The disadvantage of the second solution is the low accuracy of the dead center setting and the possibility of only rough reading of the size of the automatic transverse feed. For both solutions, you’ll need to set both dead centers separately, and determining the amount of lateral displacement is inconvenient

Uvedené nedostatky odstraňuje zariadenie na nastavovanie priečnych úvratí a odčítavanie vel-, kosti automatického priečneho posuvu, pozostávajúce z nastavovacieho a odčítavacieho mechanizmu a sústavy narážok, ktoré sú prostredníctvom mechanického převodu přepojené s týčou, opatřenou skrutkovou dráhou, do ktorej zapadá palec pevne spojený so saňami, podlá vynálezu, ktorého podstata spočívá v tom, že na hriadeli s nákružkom je posuvné uložený narážkový kotúč prednej úvrate opatřený predným obvodovým výstupkom a unášavo spojený s hriadeiom unášacím prvkom a dutý hriadel s narážkovým kotúčom zadnej úvrate, s ktorým je spojený pevne poisťovacím prvkom.
