(54) ГИДРАВЛИЧЕСКИЙ ЛЮНЕТ(54) HYDRAULIC LUNET
1one
Изобретение относитс к станкостроению, в частности к устройствам дл поддержани и центрировани заготовок типа вал в процессе их обработки на металлорежущих станках:The invention relates to a machine tool industry, in particular, to devices for maintaining and centering shaft-type workpieces during machining on metal-cutting machines:
Известен гидравлический самоцентриру .ющий люнет, выполненный в виде корпуса, в расточках которого помещены поршни, штоки которых несут губки, взаимодействующие с обрабатьюаемой деталью и кинематически св занные между собой поворотными секторами и механизмом запитки поршней с нажимным поршнем 1 .A hydraulic self centering center is known. It is made in the form of a housing, in the bores of which there are pistons, the rods of which carry sponges, which interact with the workpiece and which are kinematically connected with each other by rotating sectors and the mechanism of powering the pistons with the pressure piston 1.
Недостатком этого устройства вл етс то, что конструкци люнета, вл сь неразъемной , ограничивает использование этого устройства по диаметральному диапазону и затрудн ет установку детали, а также требует специальной подготовки обрабатываемой детали в месте установки люнета - люнетной шейки.A disadvantage of this device is that the design of the lunette, being one-piece, limits the use of this device to the diametral range and complicates the installation of the part, and also requires special preparation of the workpiece at the place of installation of the lunette — luminette neck.
Известен также гидравлический люнет, содержащий три рабочих гидроцилиндра со штоками, взаимодействующими с обрабатываемой деталью, гидравлический компенсатор со ступенчатым золотником с количеством ступеней, равным количеству гидроцилиндров, одна торцова полость которого св зана с напорной магистралью, а торцовые полости ступеней св заны с бесшток овыми полост ми гидроцилиндров. Кроме того, в гидросистеме установлен реверсивный золотник 2.Also known is a hydraulic rest, containing three working cylinders with rods interacting with the workpiece, a hydraulic compensator with a stepped slide valve with a number of steps equal to the number of hydraulic cylinders, one end cavity of which is connected to the pressure line, and the end cavities of the steps are connected to a rodless cavity mi hydraulic cylinders. In addition, a reversing spool 2 is installed in the hydraulic system.
При обработке детали с использованием этого люнета в св зи с наличием общего When machining a part using this rest, due to the presence of a common
10 компенсатора дл всех рабочих гидроцилиндров микронеровности и другие погрешности геометрической формы детали (некруглость, овальность и т.д.) вызывают одновременный отвод всех штоков и деталь во врем об15 работки остаетс безопорной.10 of the compensator for all working hydraulic cylinders, microroughness and other errors of the geometrical shape of the part (out-of-roundness, ovality, etc.) cause all rods to simultaneously retract and the part remains unsupported during machining.
Цель изобретени - повышение производительности труда при механической обработке деталей с ломошью гидравлического люне2Q та путем обеспечени возможности базнровани люнетом детали с необработанной поверхностью .The purpose of the invention is to increase labor productivity in the machining of parts with a hydraulic ram 2Q, by enabling the platform to ground the part with an untreated surface.
