本发明的功能原理和工作原理 Functional principle and working principle of the invention
1. 功能原理： 液压容器或油缸大于可视度量尺测量管， 例如采用圆 形液压容器或油缸， 其直径大， 而安装之上的可视读数尺测量管直径小， 液压容器或油缸活塞移动的距离与截面积之积， 使排出的这些液压油全部进入
可视度量读数尺测量管， 由千可视度量读数尺测量管截面积成倍小于液压 容器或油缸的截面积，那么，在可视度量尺测量管移动的距离就成倍放大。 1. Functional principle: The hydraulic container or cylinder is larger than the visual gauge measuring tube. For example, a circular hydraulic container or cylinder has a large diameter, and the visible reading gauge on the mounting has a small diameter, and the hydraulic container or the cylinder piston moves. The distance between the distance and the cross-sectional area, so that all of the discharged hydraulic oil enters The visual metric reading scale measuring tube is multiplied by the cross-sectional area of the hydraulic container or the cylinder by the measuring gauge of the visual measuring scale. Then, the distance of the measuring tube in the visual measuring scale is doubled.
2、 计算公式： 2. Calculation formula:
设液压容器或油缸的液位变量体积为 V 大， Set the liquid volume variable volume of the hydraulic container or cylinder to be V,
设液压容器或油缸的液位变量高度为 h， Set the height of the liquid level variable of the hydraulic container or cylinder to h,
设液压容器或油缸的半径为 R, 面积为 π ΙΙ2, Let the hydraulic container or cylinder have a radius of R and an area of π ΙΙ 2 .
则液压容器或油缸的液位变量体积 V = π ! ; Then the liquid volume variable volume of the hydraulic container or cylinder V = π ! ;
又设可视读数尺测量管的液位变量体积为 V 小， Moreover, the liquid level variable volume of the visual reading scale measuring tube is V,
可视读数尺测量管的液位变量长度为 L, The liquid level variable length of the visual scale measuring tube is L,
可视读数尺测量管的半径为 r, 面积为 π ι·2; The visual reading ruler has a radius r and an area of π ι· 2 ;
则可视读数尺测量管的液位变量体积 V 小 = π r2L0 Then the liquid level variable volume V of the visual reading scale measuring tube is small = π r 2 L 0
因液压容器或油缸的液位变量排出液体体积 V 等于可视读数尺测量 管的液位变量进入的液体体积 V 小， 所以 V 大 = V 小， 亦即 π ! 21ι - π r2L, L/h=R2/r2 0如果液压容器或油缸半径为 1米、可视读数尺测量管半径为 0. 1 毫米， 放大倍数 L/h=R2/r2= (1000毫米） 7 ( 0. 1毫米） 2=1亿倍。 The volume V of the liquid discharged from the liquid level variable of the hydraulic container or the cylinder is equal to the volume V of the liquid entering the liquid level variable of the measuring tube, so V is large = V is small, that is, π ! 2 1ι - π r 2 L, L/h=R 2 /r 2 0 If the hydraulic vessel or cylinder has a radius of 1 m and the visible reading tube has a radius of 0.1 mm, the magnification L/h = R 2 /r 2 = (1000 mm) 7 (0.1 millimeters) 2 = 1 billion times.
3. 按圆柱形液压容器或油缸半径为 1米和圆柱形可视度量读数尺测 量管半径为 0. 1毫米比例， 化作微米为 100 0 00(H敫米比 100微米， 半径 长度比为 10000: 1 。 3. According to the cylindrical hydraulic container or cylinder with a radius of 1 m and a cylindrical visual metric reading scale, the measuring tube radius is 0.1 mm, and the micron is 100 00 (H 敫 to 100 μm, the radius length ratio is 10000: 1 .
截面积比计算为： The cross-sectional area ratio is calculated as:
1 000 000x1 000 000x3. 14= 3 140 000 000 000平方敖米 1 000 000 x 1 000 000 x 3. 14 = 3 140 000 000 000 square meters
100x100x3. 14=31400平方微米 100x100x3. 14=31400 square micron
面积比为： 100 000 000: 1那么， 液压容器或油缸的活塞压缩 1 米 时， 有 3140 000 000 000立方微米的液压油进入到截面积为 31400平方 微米的可视度量尺测量管内， 行程距离长度为 100 000 000微米， 可视位 移放大了一亿倍。 同样， 肉眼很难发现的液压容器或油缸的活塞位移 0.
00001微米时，流入可视度量尺测量管的液压油行程距离长度是 1000微米， 即肉眼可视长度为 1毫米， 精确巧妙地测出了肉眼很难发现的活塞位移 0. 00001微米的微小变化。 The area ratio is: 100 000 000: 1 Then, when the piston of the hydraulic container or cylinder is compressed by 1 m, 3140 000 000 cubic micrometers of hydraulic oil enters the visible measuring tube with a cross-sectional area of 31,400 square micrometers. With a length of 100 000 000 microns, the visual displacement is magnified 100 million times. Similarly, the piston displacement of a hydraulic container or cylinder that is difficult to find with the naked eye is 0. 00001 microns, the hydraulic oil travel distance into the visual measuring tape measuring tube is 1000 microns, that is, the visual length of the naked eye is 1 mm, and the small displacement of the piston displacement 0. 00001 micron which is hard to find by the naked eye is accurately and skillfully measured. .
同样， 用 5个 20厘米半径的圆柱形液压容器或油缸与 0. 1毫米半径 可视度量读数尺作为复合液压容器或油缸， 当液压容器或油缸的活塞全部 压缩 米时， 有 3140 000 000 000立方啟米的液压油进入到截面积为 31400平方微米的可视度量尺内， 行程距离长度为 100 000 000微米， 可 视位移放大了一亿倍。 同样， 肉眼很难发现的液压容器或油缸的活塞位移 0. 00001微米时， 流入可视度量尺的液压油行程距离长度是 1000微米， 即肉眼可视长度为 1毫米， 变相测出了肉眼很难发现的活塞位移 0. 00001 微米的微小变化。 这个原理是精确测量长度、 面积、 体积、 容积、 压力、 准确位移的有效依据。 结合实际应用， 根据不同需求， 任意调节液压容器 或油缸半径与可视度量尺半径比， 完全可以满足不同机床、 不同行业、 不 同机械的特殊结构条件下的对体积小而加工精密度高的要求。 Similarly, use five cylindrical hydraulic vessels or cylinders with a radius of 20 cm and a 0.1 mm radius visual metric reading scale as a composite hydraulic vessel or cylinder. When the piston of the hydraulic vessel or cylinder is fully compressed, there are 3140 000 000 000 The hydraulic oil of the cubic meter enters into a visual scale with a cross-sectional area of 31,400 square micrometers. The travel distance is 100 000 000 micrometers and the visual displacement is magnified 100 million times. Similarly, when the displacement of the piston of a hydraulic container or cylinder that is difficult to be visually recognized by the naked eye is 0. 00001 μm, the length of the hydraulic oil flowing into the visual scale is 1000 μm, that is, the visible length of the naked eye is 1 mm, and the disguise is very close to the naked eye. Difficult to find piston displacement 0. 00001 microscopic small changes. This principle is an effective basis for accurate measurement of length, area, volume, volume, pressure, and accurate displacement. According to the actual application, according to different needs, the hydraulic vessel or cylinder radius and the visual gauge radius ratio can be adjusted arbitrarily, which can meet the requirements of small volume and high precision in the special structural conditions of different machine tools, different industries and different machines. .

测距工作前， 关闭加液压油的孔管。 连杆受外力作用， 推动连接活塞 压力片， 活塞在液压容器或油缸里移动时， 容器内的液压油受压力影响， 被压进液量可视管， 当液量可视管冒出液压油时， 容器内形成充满油无空 气状态， 进入测距状态。 Before the distance measurement work, close the hole tube with hydraulic oil. The connecting rod is subjected to an external force to push the piston pressure piece. When the piston moves in the hydraulic container or the cylinder, the hydraulic oil in the container is affected by the pressure, and is pressed into the liquid quantity visual tube. When the liquid quantity is visible, the hydraulic oil is generated. When the container is filled with oil and airless state, it enters the ranging state.
先确定测物的厘米和毫米长度， 按需要分别装上可视厘米读数尺测量 管， 毫米可视读数尺测量管、 微米读数尺测量管， 当活塞继续受力时， 压 进可视厘米读数尺测量管的液压油， 就是换算得到的厘米读数， 同样， 压 进可视毫米读数尺测量管的液压油， 就是换算得到的毫米读数， 压进可视 微米读数尺测量管液压油就是换算得到的微米读数， 换算得到纳米读数。
被压出的液压油， 可全部回收至转换的液压容器或油缸， 通过压缩活塞， 象注射器一样， 再次压进液压容器或油缸进行循环测量。 First determine the centimeter and millimeter length of the object, and install the visual centimeter reading tube, millimeter visual reading scale measuring tube, and micrometer reading tube measuring tube as needed. When the piston continues to be stressed, press the visual centimeter reading. The hydraulic oil of the measuring tube is the converted centimeter reading. Similarly, the hydraulic oil that is pressed into the measuring tube of the visible millimeter is the converted millimeter reading. Pressing the visible micrometer to the measuring tube is the conversion of the hydraulic oil. The micrometer readings are converted to nanometer readings. The hydraulic oil that has been pressed out can be completely recovered to the converted hydraulic container or cylinder, and compressed by the compression piston, like a syringe, into the hydraulic container or cylinder for cyclic measurement.
本发明巧妙地利用液压容器或油缸与测量管口径大小的差异， 实现液 位变量， 使被测量的长度、 面积、 体积、 流量、 压力、 位移等数值在小口 径测量管可视液量读数尺上成千上万倍放大， 因而能突破传统技术测量只 能达到毫米级的局限， 本发明解决了测量技术领域的这些技术难题， 精度 可达到微米级、 纳米级 ， 是测量计量技术领域的一次飞跃和突破。 本发 明构思巧妙， 设计合理， 原理可靠， 简单实用， 适应飞速发展的工农业生 产、 国防建设和科研工作的需求， 为科学技术的进步提供了一种方便、 适- 用、 可靠、 科技含量高的新型计量方法和装置， 应用极其广泛。 The invention skillfully utilizes the difference between the size of the hydraulic container or the cylinder and the measuring tube, and realizes the liquid level variable, so that the measured length, area, volume, flow, pressure, displacement and the like are in the small-diameter measuring tube visible liquid amount reading scale. Thousands of times of amplification, so that it can break through the limitations of traditional technology measurement can only reach the millimeter level.

The invention adopts one or more hydraulic containers or cylinders with different shapes and different structures, and the liquid level variable accurately measures the object. The principle is: the piston in the hydraulic container or the oil cylinder compresses the hydraulic oil, and the hydraulic oil flows into the liquid volume visual tube.
