Description

(5k} УСТРОЙСТВО ДЛЯ КОНТРОЛЯ соосности РЕЗЬБЫ ГАЙКИ С ЕЕ НАРУЖНОЙ ПОВЕРХНОСТЬЮ(5k} DEVICE FOR CONTROL OF THE ALIGNMENT OF THREAD OF A NUT WITH ITS OUTER SURFACE

1 .. . .; Изобретение относитс  к техничес кому контролю в машиностроении, а именно к контролю гайки шариковин- , ТОБОЙ пары. Известны устройства дл  контрол соосности наружной и внутренней поверхностей детали, содержащие две опоры, на которые ложитс  провер ема  деталь своей внутренней поверхностью , и отсчетную головку, наконечник которой установлен против одной из опор С13.. Однако при вращении издели  со сквозными окнами износ опор резко во растает. Известны также устройства дл  контрол  соосности резьбы гайки с ее.наружной поверхностью, содержащие корпус, закрепленный на нем узел-базировани  гайки, выполненный в виде призмы с осевым упором, подвижную по направл ющим корпуса вдоль оси резьбы каретку и измерительный узел, закрепленный на карет ке, с наконечником, контактирующим с профилем резьбы 12. Однако при контроле гаек с дуговым профилем т говое усилие, передаваемое с наконечника на каретку, смещает наконечник вдоль оси резьбы, увод  его с нижней точки профил . Цель изобретени  - повышение точности контрол  гаек с дуговым профилем резьбы, пересеченной окнами. Эта цель достигаетс .тем, что каретка снабжена шарнирно подвешенной к ней подпружиненной т гой и шарнирно подвешенной к т ге ведущей гребенкой , взаимодействующей с контролируемой гайкой. На фиг. 1 представлено устройство , осевое сечение, на фиг. 2 - разрез А-А на фиг. 1. На корпусе 1 устройства установлен узел базировани  в виде призмы 2, торец которой служит осевым упором . Провер ема  гайка 3 устанавливаетс  в призму до упора буртикомone .. . ; The invention relates to technical control in mechanical engineering, in particular to the control of a ball nut, YOU of a pair. Devices are known for controlling the coaxiality of the outer and inner surfaces of the part, which contain two supports on which the checked part rests with its inner surface, and a readout head, the tip of which is installed against one of the supports C13 .. However, when the product rotates through the windows, will melt. Also known are devices for controlling the coaxiality of the nut thread with its outer surface, comprising a body, a nut-based nut fixed on it, made in the form of a prism with an axial stop, a carriage moving along the body guides along the thread axis and a measuring node fixed on the carriage , with a tip in contact with the thread section 12. However, when checking the nuts with an arc profile, the pulling force transmitted from the tip to the carriage displaces the tip along the thread axis, leading it away from the lower point of the profile. The purpose of the invention is to improve the accuracy of control of nuts with an arc profile of the thread crossed by windows. This goal is achieved. The carriage is provided with a spring-loaded thrust and a leading comb that is pivotally suspended from it and which interacts with the controlled nut. FIG. 1 shows the device, axial section; FIG. 2 shows section A-A in FIG. 1. On the device case 1, a base unit is installed in the form of a prism 2, the end of which serves as an axial stop. Checkable nut 3 is installed in the prism against the stop by the shoulder

s ее торец. В направл ющих k корпуса 1 установлена каретка 5 подвижна  вдрль оси резьбы. На каретке 5 закреплен измерительный узел, наконечник 6 которого входит во впадину провер емой резьбы. К каретке подвешена на шарнире подпружиненна  т га 7 а к последней, также на шарнире - ведуща  гребенка 8.s its butt. In the guides k of the housing 1, a carriage 5 is mounted movably along the axis of the thread. A measuring unit is fixed on the carriage 5, the tip 6 of which enters the cavity of the tested thread. A spring-loaded tg ha 7 is suspended on a hinge to the carriage, and the leading comb 8 is also hinged to the latter, also on a hinge.

Дл  контрол  соосности резьбы и наружной цилиндрической поверхности гайки 3 ее устанавливают в призму 2 до упора буртиком в торец. Затем арретируют наконечник 6 и гребенку 8 и ввод т их перемещением каре|тки 5 внутрь гайки, после чего их отпускают, ввод  в контакт с профилем резьбы. При вращении гайки 3 в призме 2 гребенка 8 через т гу 7 ведет каретку 5 вдоль оси резьбы, а наконечник 6 вследствие этого посто нно контактирует со впадиной резьбы. Наличие на гребенке 8 не менее двух в;ыступов позвол ет ей проходить без западани  через окна в гайке. Наконечник 6 имеет ограничение перемещени , что позвол ет ем самосто тельно входить в резьбу после прохода окна.To control the coaxiality of the thread and the outer cylindrical surface of the nut 3, it is installed in the prism 2 as far as it will go with the collar at the end. Then the tip 6 and the comb 8 are arrested and introduced by moving the rack 5 inside the nut, after which they are released, brought into contact with the thread profile. When the nut 3 is rotated in the prism 2, the comb 8 through tug 7 leads the carriage 5 along the axis of the thread, and the tip 6 is therefore in constant contact with the root of the thread. The presence of at least two in the comb 8; the protrusions allow it to pass through the windows in the nut without zapastan. The tip 6 has a movement restriction, which allows it to enter the thread itself after the passage of the window.

Таким образом, при контроле гаек с окнами и дуговым профилем резьбы обеспечиваетс  контакт наконечникаThus, when inspecting the nuts with windows and the arc profile of the thread, contact tip is provided.

с дном впадины профил , что повышает точность измерени .with the bottom of the hollow profile, which improves the measurement accuracy.
