Description

Изобретение относитс  к металлообработке и может быть использовано дл  закреплени  деталей при обработк на станках.The invention relates to metalworking and can be used to secure parts when machining on machines.

Известен способ закреплени  тонко стенных деталей, при котором деталь центрируют на по сках пробок, а в полость заливают под давлением жидкость lj .There is a known method of fixing thin-wall parts in which the part is centered on the tubes, and the liquid lj is poured into the cavity under pressure.

Недостатком указанного способа  вл етс  низка  точность закреплени  деталей.The disadvantage of this method is the low accuracy of fixing parts.

Наиболее близким к предлагаемому  вл етс  способ закреплени  тонкостенной детали, при котором в полость производ т заливку жидкости, затвердевающей при охлаждении 2J .Closest to the present invention is a method for securing a thin-walled part, in which a fluid is filled into the cavity, which solidifies upon cooling 2J.

Недостатком известного способа  вл етс  низка  точность закреплени  детали.The disadvantage of this method is the low accuracy of fixing the part.

Цель изобретени  - повышение точности закреплени .The purpose of the invention is to improve the accuracy of fixing.

Указанна  цель достигаетс  тем, что согласно способу закреплени  тонкостенной детали, при котором в полость детали производ т заливку жидкости, затвердевающей при охлаждении , перед запивкой жидкости в полость вставл ют трубку, выполненную из материала, стойкость при деформации которого ниже, чем стойкость при деформации детали.This goal is achieved by the fact that according to the method of fixing a thin-walled part, in which a fluid hardening during cooling is filled in the part cavity, a tube made of a material whose resistance to deformation is lower is inserted into the cavity before flushing the liquid .

Такое выполнение повышает точнос закреплени  детали, исключа  ее коробление .This embodiment improves the accuracy of fixing parts, eliminating its distortion.

На чертеже предстпплена схема, п сн юща  способ закреплени  детали.The drawing is a diagram showing the method of fixing the part.

Способ осуществл етс  следующим образом.The method is carried out as follows.

В деталь 1 вставл ют эластичную крьшку 2 с конической трубкой 3, выполненной из материала, стойкость при деформации которого ниже, чем стойкость при деформации детали 1, Верхнюю часть детали 1 закрывают крышкой 4 с отверстием 5 дл  залива жидкости 6 и отверстием 7 дл  слива излишков жидкости. После заливки жидкости, например воды, производ т ее замораживание при температуре -13 - 15 С. При замерзании воды излишки ее вытесн ютс  через отверсти 7, а дальнейшее расширение льда компенсируетс  -пустотелой эластичной трубкой 3, принимающей на себ  все последстви  механической деформации детали, снижа  таким образом напр жени , возникающие в детали при замораживании собранного узла. После замораживани  деталь готова к механической обработке поверхности .In part 1, an elastic cap 2 is inserted with a conical tube 3 made of a material whose resistance to deformation is lower than that when part 1 is deformed. The upper part of part 1 is covered with a lid 4 with an opening 5 for filling the liquid 6 and an opening 7 for draining the excess fluid. After pouring a liquid, such as water, it is frozen at a temperature of -13 - 15 ° C. When water freezes, its excess is forced out through holes 7, and further expansion of the ice is compensated for by a hollow body tube 3, which takes on all the consequences of the mechanical deformation of the part, thus reducing the stresses arising in the part during freezing of the assembled unit. After freezing, the part is ready for mechanical surface treatment.

Технико-экономическа  эффективность при применении изобретени  обусловлена повышением точности закреплени .Technical and economic efficiency in the application of the invention is due to the increased accuracy of fixing.
