(54) ПНЕВМАТИЧЕСКОЕ УСТРОЙСТВО ДЛЯ КОНТРОЛЯ ПОВЕРХНОСТИ(54) PNEUMATIC DEVICE FOR SURFACE CONTROL
1 . one .
Изобретение относитс к измерительной технике н может быть нспользовано дл контрол остроты режущих кромок инструментов.The invention relates to a measurement technique that can be used to control the sharpness of the cutting edges of tools.
Известны устройства дл контрол формы и шероховатости поверхности, содержаодае пневматическую оснастку и сообщенный с . оснасткой манометр (11О качестве поверхности суд т по давлению воздуха в оснастке.Devices are known for controlling the shape and surface roughness, containing pneumatic tooling and communicating with. equipment pressure gauge (11On surface quality is judged by the air pressure in the equipment.
Наиболее близким к изобретению вл етс пневматическое устройство дл контрол поверхности , содержащее полый корпус с отверстием , перекрывающую отверстие упругую пленку, источник давлени и манометр, сообщенные с корпусом. Упруга пленка контактирует с контролируемой поверхностью и по ее размерам можно косвенно судить о состо нии режущей кромки инструмента 2. Однако известные устройства не позвол ют контролировать непосредственно остроту режущей кромки инс1румента.Closest to the invention is a pneumatic device for controlling the surface, comprising a hollow body with an opening, an elastic film overlying the opening, a pressure source and a pressure gauge communicated with the housing. The elastic film is in contact with the controlled surface and it is possible to indirectly judge from the size of the cutting edge of the tool 2. However, the known devices do not directly control the sharpness of the cutting edge of the tool.
Цель изобретени - обеспечение возможности контрол остроты режущей кромки.The purpose of the invention is to provide the ability to control the sharpness of the cutting edge.
Эта цель достигаетс тем, что предлагаемое устройство снабжено рамкой, подвижной к отверстию корпуса, а пленка выполнена в виде ленты, оснащенной по кра м нераст гИвающимис нит ми и установленной с возможное тью перемещени между корпусом и рамкой. Рамка оснащена заслонкой подвижной в плоскости рамки.This goal is achieved by the fact that the proposed device is provided with a frame movable to the opening of the housing, and the film is made in the form of a tape, fitted along the edges with non-expanding threads and installed with possible movement between the housing and the frame. The frame is equipped with a slide valve moving in the plane of the frame.
На фиг. 1 представлено описываемое устройство , общий вид; на фиг. 2 - принщ1пи0 альна схема устройства.FIG. 1 shows the described device, a general view; in fig. 2 - prischen1podna the scheme of the device.
Устройство содержит полый корпус 1, источник давлени в виде резиновой грущи 2, сжимаемой толкателем 3, и манометр 4 низкого давлени с обратным клапаном 5, дренажным The device comprises a hollow body 1, a pressure source in the form of a rubber duct 2 compressed by the pusher 3, and a low pressure gauge 4 with a check valve 5, a drainage
5 клапаном 6. В корпусе I устройства выполнено отверстие, перекрытое упругой резиновой лентой 7 толйшной С 0,1 мм. Во избежание продольного раст гивани лента 7 по кра м оснащена нераст гивающимис , например, шелковыми нит ми 8. Лента 7 первоначально намотана на катушку 9 и перематываетс на катушку 10 при вращении ручки 11. Плотное герметичное прилегание ленты 7 к отверстию5 with a flap 6. In the case of the device I there is a hole, covered with an elastic rubber band 7 thick With 0.1 mm. In order to avoid longitudinal stretching, the tape 7 along the edges is equipped with non-expandable, for example, silk threads 8. The tape 7 is initially wound on the coil 9 and rewound on the coil 10 as the handle 11 is rotated.
715934 корпуса 1 обеспечиваетс рамкой 12 с шиберной заслонкой 13, и пружиной 14, установленной между скобкойкорпуса 1 и планкой 15И На раме 12 выполнены упоры 16, Перед началом контрол остроты режущей кромки инс1румента 17 перемещением ишбер ной заслонки 13 устанавливаю ширину в пр в рамке 12 в соответствии с длиной режущей кромки, - Устройство работает следующим образом. Инструмент 17 устанавливают режущей кромкой в упоры 16, нажимают на толкатель 3 и подают воздух из груши 2 в полость корпуса 1. Под действием давлени воздуха лента 7 прижимаетс к режущей кромке и пр резаетс . Давление, при котором разрезаетс лента, фиксируетс манометром 4 и служит показателем остроты кромки. По окончании изм ерейи из полости манометра 4, отдел емой от атмосферы обратнь1м клапаном 5, дрсдаруетс .воздух через клапан 6 и вращением ручки 11 разрезанный участок ленты перематываетс за пределы рамки 12. .д715934 of housing 1 is provided with frame 12 with gate valve 13, and spring 14 installed between bracket 1 and bracket 15I. Frame 16 has stops 16, Before starting to check the sharpness of the cutting edge of tool 17, I set the width in the frame 12 in according to the length of the cutting edge, - The device works as follows. The tool 17 is mounted with the cutting edge into the stops 16, the push rod 3 is pressed and the air from the pear 2 into the cavity of the housing 1 is pressed. Under the action of air pressure, the tape 7 is pressed against the cutting edge and cut. The pressure at which the tape is cut is recorded by a pressure gauge 4 and serves as an indicator of the sharpness of the edge. At the end of the measurement, the cavity of the manometer 4, which is separated from the atmosphere by the reverse valve 5, is dredged. The air through the valve 6 and by rotating the knob 11 rewinds the cut tape outside the frame 12..
