Description

一种电子数显卡尺 An electronic digital calipers

技术领域 FIELD

本发明涉及一种电子数显卡尺类量具,主要用于精密测量外径和厚度等。 The present invention relates to an electronic digital caliper gage type, mainly used for precision measurement of the outer diameter and thickness. 背景技术: Background technique:

经网上检索专利文献和《机械制造》、《工具技术》、《机械工程师》等有关刊物目录,及国内量具生产厂家的产品介绍,均未发现和本发明结构类似的一种电子数显卡尺。 Through the Internet search patent literature and "machinery", "tool technology", "mechanical engineer" and other related publications catalog, and measuring domestic manufacturer of the product introduction, it was not found and the structure of the invention similar to an electronic digital calipers.

在现有技术中,众所周知,国内外广泛使用的电子数显卡尺, 一般分辨率为0.01咖,即最小可读值为0. Olmm,但示值误差达土O. 03mm,且测量范围越大,它们的示值误差越大。 In the prior art, is well known, an Electronic Digital Caliper widely used at home and abroad, typically coffee resolution of 0.01, i.e., the minimum value is readable 0. Olmm, but showing the error of soil O. 03mm, and the larger measuring range , the greater the indication error thereof.

现有数显卡尺虽均有结构简单、使用方便、用途广泛、测量范围较大等优点,但其测量精度均不及一般示值范围间隔为25mm规格的普通千分尺。 Although conventional digital calipers are simple in structure, easy to use, versatile, large measurement range, etc., but the measurement accuracy is not shown and typically range specifications of the ordinary interval of 25mm micrometer. 该类最广泛使用的千分尺,可读值为O.Olmm, 一级品0-25mm规格的,示值误差为土0.004mm。 The most widely used of such micrometer-readable value O.Olmm, 0-25mm a product specification, the indication error of soil 0.004mm. 测量精度更高的杠杆千分尺和杠杆卡规及微米千分尺,属千分尺类的精品,示值误差为土0.002mm。 Higher measurement accuracy lever and the lever micrometer caliper and micrometer microns, is fine micrometer class indication error for the soil 0.002mm. 但由于可读测微范围或量程有限及价格高等因素制约,在一般企业的一线车间里运用并不普遍,据说大多为检验员使用。 However, due to the limited readable micrometer range or higher range and price factors, general business use is not common in first-line workshop, reportedly mostly inspectors use.

由于精密量具、量仪类大多价格较高或昂贵且测微范围较小,有的对一线生产环境难以适应等诸多因素的存在,使正在向数字化、高速、高效、高精加工方向发展的机械制造业的一线车间里,有许多按公差与配合等级要求本应使用精密量具测量的工件,常常被迫使用游标卡尺、数显卡尺或一般千分尺去进行费时费力且难度很大的高精度测量。 Due to the mechanical precision measuring tools, measuring instruments or classes mostly higher prices and less expensive micrometer range, there are some difficult to adapt to the environment of the production line and many other factors that are moving to digital, high-speed, high efficiency, high precision direction development line manufacturing workshop, there are a lot of tolerance and cooperation according to the requirements of this level of precision measuring tools should be used to measure the workpiece, often forced to use a vernier caliper, digital caliper or micrometer general to carry out time-consuming and very difficult high-precision measurements. 这不但影响产品质量,也阻碍生产率的进一步提高。 This will not only affect product quality, but also hinder further improve productivity. 这些都是通用量具精密化技术发展滞后造成的。 These are general gauge precision technology development lags caused.

发明内容: SUMMARY:

本发明的目的就在于克服上述现有技术的不足之处,提供一种结构简单, 耐用且特别能适用于一线车间生产人员和检验员等使用的高精确度电子数显卡尺。 Object of the present invention to overcome the shortcomings of the prior art described above, to provide a simple, robust and particularly applicable to the production plant personnel and line inspectors and the like with high accuracy using an Electronic Digital Caliper. 该尺最低设计标准的起点为可读值0. OOlmm,示值误差应为土O. 003mm, 较高精度的,其可读值便进入微米以外的区域。 The starting point for the minimum design criteria for the foot-readable value 0. OOlmm, indication error should soil O. 003mm, high accuracy, which will enter the region other than the read value of m.

本发明是这样实现的。 The present invention is achieved.

本发明的电子数显卡尺,主要是把已被现有电子数显卡尺运用的容栅测 Electronic Digital Caliper of the present invention, has been used mainly to an Electronic Digital Caliper conventional capacitive sensing

量系统,应用到本人的另一项已申请专利--种高精度游标卡尺中去,该 Volume system, another application to my patented - species go precision vernier caliper, the

专利申请号:2005100174644。 Patent application number: 2005100174644. 从而实现更快速度的高精度测量及测量结果的数字化显示。 Whereby high-precision digital measurement and measurement results faster display speed. 本发明的一种电子数显卡尺,主尺正面有一条与主尺下部斜面平行的浅槽,槽内装有定栅,定栅外贴保护膜。 An electronic digital calipers according to the present invention, the main scale front shallow groove and a lower portion of a main scale ramp parallel grooves with a given gate, the gate exo stick protective film. 带数显卡尺显示器的盖板固定在尺框的两导向板之间,使显示器与定栅组成有效的容栅数显测量系统。 Cover with digital calipers display the guide plate is fixed between the two foot frame, and fixed so that the display grid consisting effective capacitive digital measuring system. 浅槽上方有一条与其平行的导向槽。 Above the shallow groove parallel thereto a guide groove. 定栅、显示器、浅槽、导向槽、尺框倾斜导轨以及主尺下部斜面的倾斜角度均相同。 Fixed gate, a display, a shallow groove, the guide groove, and a lower rail foot frame inclined slope inclination angle of the main scale are the same. 主尺前端有一安全螺丝,主尺尾部及尺框上测量时人手接触处均须设置隔热件,以防体温影响测量效果。 The front end of the main scale has a security screw, the hand touching the main scale to be provided with thermal insulation as measured on the tail and foot frame, to prevent the temperature affect the measurement results. 主尺的上平面即为主尺上的量爪面。 I.e. the main plane of the scale based on the amount of foot jaw face. 主尺上平面与尺框上朝下的各量爪面平行。 The amount of the main scale on each jaw face downward on a plane parallel to the foot block. 当主尺上平面与O-IO量爪面无隙接触时,本尺处于可校零状态。 When the main scale on the contact plane of the O-IO jaws surface without gaps, the foot is in a state of zeroing. 此时, 主尺上平面与尺框里的上平面间仍留有lmm左右垂直空间。 In this case, between the main scale and the scale on the plane of the box on a plane vertical space still remains about lmm. 主尺上平面与尺框上各量爪面、及尺框上平面、底平面平行,与各导向板、主尺自身两侧面垂直。 The amount of the main scale on each jaw face on a plane scale frame and the foot frame plane, parallel to the bottom plane, with the guide plates, side surfaces perpendicular to the main scale itself. 尺框量爪面的数量,优选地,可为一个或多个,该尺所用角度的函数值越小,量爪面可设数越多,量爪面越多,总示值范围越大。 Number jaws foot block surface, preferably, may be one or more, the scale used by the function value of the angle is smaller, the number of jaws may be provided more surfaces, the more the amount of the claw face, the larger the total value range shown. 量爪悬伸长度越长可设的量爪面就越多。 The longer the more the amount of the jaw face may be provided jaws overhang.

量爪面之间的落差相等,且分别等于主尺拟定的最佳升程为最佳。 An amount equal to the gap between the jaw faces, respectively, equal to the main scale and the best formulation for the best lift. 因为这样就多一个量爪面,示值范围就可扩大。 Because the more the amount of a jaw face, showing the value range can be expanded.

主尺在尺框里允许的纵向移位量的最大值决定主尺最大升程值。 The maximum shift amount of the main scale in the longitudinal direction of the foot allows the box main scale determines the maximum lift value. 优选地, 主尺用于测量的最佳纵向位移量长度值,由所需最佳设计升程决定。 Preferably, the main scale optimal amount of displacement of the longitudinal length of the measured values, the optimum design dictated by the desired lift. 在测量范围内,有效纵向位移量乘该尺所用锐角对应的正弦值等于拟定主尺的有效升程。 Within the measurement range, an effective amount of longitudinal displacement by the scale corresponding to the sine of the acute angle which is equal to the effective formulation of the main scale lift. 在取相同角度时,主尺有效升程越大,示值范围越大。 When taking the same angle, the effective lift of the main scale, the greater the range shown.

尺框上量爪面的上方侧面上,标有该量爪面的测量范围,如标注数为 The frame above the foot on the side surface of the jaws, marked with a measurement range of the surface of the jaws, such as the number of labeled

40-50mm时,则表示该量爪面可测①40-①50或厚度为40mm-50咖的工件或零件;标注为0-lOmm,则表示可测量0-10mm尺寸大小的工件或零件。 When 40-50mm, it indicates that the amount of measurable jaw face ①40-①50 40mm-50 or a thickness of the workpiece or part of coffee; labeled 0-lOmm, said measure 0-10mm size of the workpiece or part. 以此类推。 And so on. 事实上因主尺前端预留了伸出导轨的一部分长度,每量爪面均可测量稍大于其最大可测值的零件。 In fact due to the main scale length of the distal end portion extending aside the rail, each of the jaws is slightly larger than its surface parts can be measured maximum measurable value.

当主尺上平面距0-10mm量爪面垂直距离为lOmm时,主尺的上平面即主尺的量爪面,与尺框上各量爪面间的垂直距离,为各量爪面上方标注的最大可测值。 When the main scale vertical distance from the plane surface is 0-10mm lOmm jaws, i.e. the main scale on the main plane surface feet jaws, the vertical distance between the surfaces of the jaws on the foot block denoted for the side surface of the jaws the maximum measurable value. 在以正弦值0.1选取该尺斜角时,尺框上量爪面若有标注较小测量范围值,如0-10mm 0-5mm等等,则主尺在尺框里纵向移动至主尺上平面与0-10mm量爪面为无间隙接触的校零状态时,此时主尺上平面与尺框上其它量爪面间的垂直距离为其它量爪面上方标注的最小可测范围值。 When the selected sine value 0.1 bevel foot, the foot block denoted by a smaller amount if the jaw face value of the measuring range, etc. as 0-10mm 0-5mm, the longitudinal movement of the main scale to the main scale on the ruler box when the zero state correction plane surface is 0-10mm jaws intimate contact, in which case the vertical distance between the main scale on the surface of the other jaws on a plane block is the minimum measurable scale range value other side surface of the jaws marked.

当完全采用现有数显卡尺的容栅测量系统配置时,主尺的斜面和尺框里导轨的倾斜角的正弦值可在包括Ol在内的由0.1趋近于0的值中选取。 When the number of completely conventional calipers capacitive measurement system is configured, the main scale and the bevel foot guide box sine tilt angle can be selected including Ol including close to zero by the value of 0.1. 优先地应选择O. 1 0.01 0.001 O.OOOl等。 Should be selected preferentially O. 1 0.01 0.001 O.OOOl like. 理由是,仅将显示器上的数据乘本卡尺选取的三角函数值,即得0-10mm量爪面下实测工件尺寸(因清零后向后拉动主尺,会使主尺与尺框相对位移量的显示值皆带负号,故应视该负号无意义即可),故仅用小数点向前移位法即得实测值。 The reason is that only the data on the display by the present value of the trigonometric function chosen caliper, to obtain the actual size of the workpiece surface 0-10mm jaws (pulled backward by the main scale is cleared, the main scale will scale relative displacement block the amount of display values ​​are negative numbers, it should be considered that the negative sign can be meaningless), so that only the forward displacement method to obtain the decimal Found. 例如本卡尺选取的三角函数值为O. l时,如显示器显示为66. 26mm,则可直读为6. 626mm。 For example when the present value of a trigonometric function selected caliper O. l, such as a display monitor 66. 26mm, can be directly read 6. 626mm.

该卡尺上使用的容栅测量系统,可以选用现有普通电子数显卡尺使用的分辨率为0. Olmm的测量系统,也可选用分辨率达0. OOlmm的高精度容栅测量系统。 Capacitive measurement system used on the caliper, can use an existing ordinary resolution using an Electronic Digital Caliper is 0. Olmm measurement system can also be used with a resolution of 0. OOlmm precision capacitive measuring system. 二者测量精度如下表: Both the measurement accuracy as follows:

更方便读数的方案是改编显示器程序。 More convenient reading scheme is an adaptation of a display program. 如采用以下两套显示器程序设计 The following two programming display

方案,则本发明的主尺取角用的正弦值可在包括0.5在内的由0.5趋近于0 的任意值中根据需要选定。 Embodiment, the angle of the main scale by taking the sine of the present invention may be in any value of 0 in the selected approach comprises including a 0.5 0.5 required.

显示器程序设计方案如下: Display programming scheme is as follows:

1、显示值二显示器与定栅的实测相对位移Xsinci+所用量爪面下限值。 1, the display displays two values ​​measured with a given relative displacement of the gate Xsinci + lower limit of the amount of the jaw face. 例如, 零件夹在10 - 20量爪面与主尺上平面之间,显示器与定栅的实测相对位移为62. 58mm,则显示值=lOmm + 62.58mmX0. 1 =16. 258mm。 For example, the part sandwiched 10--20 jaws between the upper surface of the main scale plane, and the fixed displays the measured relative displacement of the gate 62. 58mm, value = lOmm + 62.58mmX0 1 = 16 is displayed 258mm... 测量时根据所使用的不同量爪面,按功能按钮切换量爪面下限参数值。 Depending on the amounts used in jaw faces, press the function button switch minimums jaw face measured parameter value. 2、显示值二显示器与定栅的实测相对位移Xsinci,使用人员将显示器示数与所用量爪面下限值相加得测量值,无须设置参数转换功能按钮。 2, the display displays two values ​​measured with a given relative displacement of the gate Xsinci, using the display shown will have measured the number and the sum limit value by the amount of the surface of the pawl, the parameter conversion function button need not be provided. 例如,零件夹在10-20量爪面与主尺上平面之间,显示器与定栅的实测相对位移为62. 58mm , 则显示值=62. 58mm X 0. 1 二6. 258mm 。 For example, an amount of 10-20 parts interposed between the pawl and the main scale surface plane, with a display of the measured relative displacement given to the gate 62. 58mm, the display value = 62. 58mm X 0. 1 two 6. 258mm. 零件测量值二10mm+6. 258mm=16. 258亂 Part two measurements 10mm + 6. 258mm = 16. 258 chaos

本发明电子数显卡尺的防尘技术处理,参照现有电子数显卡尺执行。 The present invention is electronic digital calipers dust technical processing, with reference to the conventional electronic digital calipers performed. 但本发明防尘软片设在导向板7和25的外侧面,有效防阻区域应覆盖导向槽及其下方的尺面。 However, the present invention dustproof film disposed on the outer side of the guide plates 7 and 25, the effective exclusion zone should cover their feet below the surface of the guide groove.

本电子数显卡尺的设计,依据物体在斜面上移动会上升或下降原理,运用直角三角形中边与边及边与角之间存在精确的正切或正弦函数关系的原理,视与主尺的上平面平行的尺框的底平面,为本发明的卡尺尺框的斜面导轨的斜角的邻边,斜面导轨为斜边,尺框左下部的端面为对边。 The principles of the electronic digital caliper design, movement of the object based on a rise or fall ramp principle, the use of the presence of a right triangle or sine function a precise relationship between the tangent between the sides and the sides of the angle of view of the main foot foot bottom plane parallel to the plane of the frame, o bevel foot rail caliper frame of the present invention bevel edge bevel hypotenuse rails, the frame foot portion to the end face on the lower left side. 因所用斜角很小,故主尺在尺框里的斜面导轨上较大的纵向位移量,对其上升位移的影响也较小。 Used by a small angle, so that the main scale greater amount in the longitudinal displacement of the inclined surface of the rail foot box, its influence is small increase in displacement. 其上升位移值还同时与该斜角即锐角大小密切相关。 It rises further at the same time shift value is closely related to the size of the angle that is an acute angle. 本卡尺所用角愈大,量程愈大。 This angle greater caliper used, greater range.

本发明的电子数显卡尺,所用斜角角度越小,容栅测量系统的分辨率对本发明的可读值精确度的影响力越小,测量精确度越高。 Electronic Digital Caliper of the present invention, the use of bevel angle, the smaller the resolution of the capacitive values ​​of the measurement system of the present invention readable accuracy influence, the higher the accuracy of measurement. 以用正弦值为0.1 取主尺和斜面导轨的斜角为例,当本发明该卡尺选用分辨率为0. Olmm的容栅测量系统时,本发明的电子数显卡尺可读值精确度已为分辨率Xsinci =0.01mmX0. 1= 0.00Iran;同理,若所选取导轨角度的正弦值为0.01,则本发明卡尺的可读值精确度应为0.01ranX0.0t O.OOOlmm。 0.1 is taken to a sinusoidal main scale and the ramp angle of the guide rail, for example, when the present invention is the selection of a resolution of 0. Olmm caliper of capacitive measuring system, an Electronic Digital Caliper readable values ​​of the present invention is the accuracy of the resolution Xsinci = 0.01mmX0 1 = 0.00Iran;. Similarly, if the angle of the rails is selected sinusoidal 0.01, the value of the present invention is the accuracy of the caliper readable should 0.01ranX0.0t O.OOOlmm. 由此亦可见,本发明的电子数显卡尺,采用正弦值为O.Ol的斜角时,事实上可读值精确度已为现有数显卡尺可读值精确度的100倍。 Thus we can see, an Electronic Digital Caliper of the present invention, a value of 100 times the sine of the angle O.Ol fact been read value Accuracy accuracy of conventional digital caliper readable values. 同理,如果采用分辨率为0. OOlmm的容栅测量系统,则可读值精确度为0.001mmX0. 1= 0. OOOlmm,可读值精确度也为现有数显卡尺可读值精确度的100倍。 Similarly, if the resolution is 0. OOlmm capacitive measuring system, accuracy of the reading can 0.001mmX0. 1 = 0. OOOlmm, the accuracy of the read value is also the value of the conventional digital caliper readable accuracy 100 times. 将此原理推广,改变本发明卡尺导轨斜角角度,即可方便的使可读值精度呈几何级数提高。 Promote this principle, the present invention is to change the caliper guide bevel angle, it can be easily readable so that the value of the exponentially increase accuracy.

本发明的电子数显卡尺,不局限于附图1示例,主要借助图1说明其结构、设计原理、运用依据、使用方法等以便审阅。 Electronic Digital Caliper of the present invention is not limited to the example of FIG. 1, FIG. 1 illustrates a main structure, design principle, according to the use, by using a method for review. 就图1示例而言,该尺亦可像普通千分尺一样形成各种不同测量范围的规格。 To Example 1, the general image of the foot may be formed as a micrometer measuring range of various specifications. 如普通千分尺, 一般设计为0-25腿、25-50mm、 50-75mm等规格,图1卡尺亦可形成0-30mm (指该尺数量爪面测量范围涵盖的区域大小)、30-60mm、 60-90mm、 90-120腿等规格。 The ordinary micrometer, generally designed for the legs 0-25, 25-50mm, 50-75mm and other specifications, the caliper of FIG. 1 may also be formed 0-30mm (number refers to a region the size of the feet the measurement range covered by the jaw faces), 30-60mm, 60-90mm, 90-120 legs and other specifications. 所测直径越大,量爪面越少,最少时为1个。 The larger the diameter measured, the less the amount of jaw faces, at least when a. 尺型较大或太大时,尺框上悬伸的量爪部分,可参照普通千分尺设计成凹弧形,以增大有益空间,容纳被测大工件的外圆表面。 When the scale type or too large, the amount of the overhanging portion of the claw foot frame, reference may be designed as ordinary micrometer concave arc, to increase the useful space for receiving a large outer peripheral surface of the workpiece under test. 尺框里与主尺上平面相对的平面至该尺框底平面部分,形态可不变,仅放大尺寸。 Opposite plane plane on the main scale and the scale box to the bottom box foot flat portion, may be the same shape, only the enlarged size.

本电子数显卡尺,无论规格多大,均应在如图一示例尺0-10mm量爪面处设一可测0-x值的量爪面,如此,即可增加本发明的电子数显卡尺的测量范围,又能保证该尺在测量前有一个精确可靠的位置为操作置零按钮的基准点。 This electronic digital calipers, no matter what size, as shown in an example should be 0-10mm jaws face of the foot provided an amount of a jaw face value can be measured in 0-x, so can increase an Electronic Digital Caliper invention measurement range, but also ensures that the ruler has a precise and reliable measurement of the position before operation button zero reference point.

OX值,可以是0-10mm,也可以是0-20mm.或0-5mm等等,应依据具体设计需要而定。 OX value, can be 0-10mm, can be 0-20mm. Or 0-5mm, etc., should be based on the specific design requirements. 总之,设0-X量爪面很重要,它是其他量爪面标注测量范围值的依据(如:当主尺上平面和该0-X量爪面呈无隙状态时,主尺上平面距尺框上的各量爪面垂直距离均分别为各量爪面上标注的最小可测范围值)。 In summary, provided 0-X jaws surface is important, it is the other jaws surface labeled according to the measurement range of values ​​(such as: when the main scale on the plane of the 0-X jaws-section gapless state, the main scale from the plane the amount of vertical distance of each jaw face on the foot frame are respectively the minimum detectable amount of the respective range of values ​​denoted jaw face). 因为ox量爪面,即是主尺向上运动的终点。 Because the amount of ox jaw faces, that is, the end of the upward movement of the main scale.

其他如:以0.5、 0.4、 0.3、 0.2……O.OOOl等三角函数值取角的电子数显卡尺,亦可参照上述方法形成系列化,形成测量范围不同、形态各异的规格品种。 Others such as: an Electronic Digital Caliper trigonometric values ​​0.5, 0.4, 0.3, 0.2 ...... O.OOOl taking angle and the like, can also form a series, forming different measuring ranges, different forms of the method described above with reference to standard varieties. 另外也可只在尺框上部设一个垂直向上的尺身,尺身上有高度尺一样尺框及其上的量爪,或者设置一个螺旋测微头等借助校对量杆或量块增大测量范围。 It may also be provided only a vertically upward at the upper foot of the blade housing, the body has a foot-foot height gauge as its jaws on the frame or provided by means of a micrometer screw top proofing blocks dipstick or increase the amount of the measurement range. 该量爪或螺旋测微头可为可分解式的固定在尺框上向前悬伸部或左端面适当部位。 The jaws or micrometer head may be suspended suitably decomposable type fixing portion or the left end face portion extending forward on the foot block. 当然本发明还可以采用其它一切有效形式。 Of course, the present invention also all other effective forms may be employed.

为使图面简洁,防尘件和尺框6上的隔热件等,均未画入图l。 To make the drawings simple, dust-foot frame member and the insulating member 6, etc., were not drawn into FIG l.

主尺1两侧面与尺框壁及导向板7、 15、 25之间呈精密配合状态,主尺l 斜面与尺框6的斜面导轨18成两斜面接触状态,主尺1导向槽4内,配合有调整螺钉19、 26,前端有与导向槽4配合的导向圆柱面,调整螺钉(应为滚花螺钉),可把主尺1锁于尺框内任意位置;导向板25被螺钉5和导向板最下面一个螺钉24压紧在尺框上下侧面上。 Scale 1 and scale side surfaces of the frame wall and the guide plate 7, 15, 25 form a precise fit state between the main scale and the scale l ramp frame rail inclined surface inclined surface 18 into two contact 6, the main scale 41 within the guide groove, blended with adjustment screw 19, 26, the front end of the guide has a cylindrical surface cooperating with the guide groove 4, the adjustment screw (screw should spend as rolling), the scale 1 can be locked in any position of the foot frame; guide plate 25 by screws 5 and a bottom guide plate 24 is pressed against the screw-foot vertical side frame. 导向板7的结构和作用与导向板25完全一样。 Structure and function of the guide plate 7 and the guide plate 25 is exactly the same. 悬伸于尺框6左上方的部分是与尺框一体的(或可分解式)量爪ll。 6 in the top left-foot overhang frame portion is integral with the foot frame (or decomposable type) jaws ll. 量爪11上有从左前方向右下方呈阶梯状分布的12、 10、 9量爪平面, 在每个量爪面上方标有其测量范围,且各量爪面落差为主尺1的最佳升程值。 There were 12, 10, 9 jaws stepped plane distribution on the lower right direction from the left front jaws 11, have their measuring range on each side surface of the standard jaws, and the jaws of each gap face of the main scale 1 is the best lift value. 各量爪面均与其下方的主尺1上平面平行,量爪侧面与主尺侧面平行,量爪11最左方前端面不允许超出尺框斜面导轨18左端面,以确保在该量爪下测量工件时,测量力落于斜面导轨18承受区域,避免主尺1承受使其右后方微翘之力。 Each of the jaws 1 on their surfaces are parallel to the plane below the main scale, the main scale the side jaws parallel to the side, a left end surface 11 of the jaws 18 of the most distal surface of the left foot must not exceed the frame rail inclined surface, to ensure that the lower jaws when measuring the workpiece, the measuring force falls to the inclined surface region subjected to the guide rail 18, so as to avoid the main scale 1 is subjected to a force slightly at the right rear. 被主尺1左前部遮挡的伸向斜面导轨18左端面的那条长虚线16, 是与尺框里框壁平行的与导向板7前端尺框连为一体的主尺后面的导向面,它由尺框壁前端一直伸向与导向板15左端面持平以增强导向能力。 The main scale 1 is blocked by the left front rail portion inclined surface toward a left end surface of the piece 18 a long dashed line 16 is parallel to the frame wall box foot guide plate 7 and the foot frame connected to the front end surface of the rear guide integral main scale, it the foot has been toward the front end of the frame wall 15 and a left end surface of the guide plate guide to enhance the capacity unchanged. 导向板15上有和螺钉14相同的三个螺钉,把导向板15固定在斜面导轨侧面上。 And have the same three of the screws 14, the guide plate 15 is fixed on the slant guide plate 15 on the side rail. 导向板15右边为图1卡尺选用的斜角三角函数值的标示17。 The right guide plate 15 is designated 17 in FIG. 1 Caliper selected angle trigonometric function value. 18是尺框里延伸出的斜面导轨,20和8是导向板7的紧固螺钉。 18 is a bevel box extending rail foot, the guide plate 20 and the fastening screw 8 is 7. 21、 22等同于显示器上部相同的三个小螺钉将显示器23固定在尺框上。 21, the upper display 22 is equivalent to the same three screws 23 fixed to the scale display frame. 安装在尺框6上的导向板及与尺框一体的用虚线16示意的导向面,与主尺的接触面必须光滑精密。 A guide plate mounted on the foot and the foot frame 6 and the frame integrally by a dashed line 16 illustrates the guide surfaces a contact surface, the main scale must be smooth and precise. 主尺应淬火,硬度必须高。 The main scale should be quenched hardness to be high. 用于测量的主尺上平面3、尺框各量爪面亦可焊接硬质合金以增加耐磨性。 For measuring the main plane of the scale 3, the frame feet also face each welding jaws in order to increase the wear resistance of cemented carbide. 总之,各量爪面硬度越高越好。 In summary, each of the jaws Surface hardness higher the better. 当主尺1上平面3与0-10 量爪面呈无间隙接触状态时,为该尺校零状态。 When an amount of 0-10 intimate contact with the pawl-section on a plane state of the main scale 3, foot correction for zero state. 这时尺框上各量爪面与主尺上平面3的垂直距离应与其标示出的最小测量范围值一致。 In this case the amount of vertical distance of each jaw face of the main plane of the scale on the scale frame 3 should be marked out therewith the measuring range of the minimum value consistent. 当主尺上平面3 向右拉至距0-10mm量爪面为10mm时,主尺上平面与10、 12两量爪面之间的距离,分别为它们上面标注的最大测量范围值。 When the main plane of the scale 3 is pulled to the right away from the surface is 0-10mm jaws 10mm, the main scale and the distance between the plane 10, two jaws 12 face, respectively, the maximum value of the measuring range marked on them.

以下叙述图1示例尺使用方法: FIG foot 1 described below use an example:

由图1主视图和AA剖面图可知,主尺1被装在尺框6里面。 It is seen from a front view and a sectional view AA of FIG. 1, a main scale 1 is mounted inside the frame 6 feet. 主尺1的上平面距尺框里的上平面的空间高度,略大于主尺1与0-lOmm量爪面之间的距离。 The main scale space height from the foot of the box on a plane on the plane 1, is slightly larger than the distance between the jaws and the 0-lOmm surface of the main scale. 拧紧调整螺钉19或26,可将主尺紧锁在尺框里,也可用于调整间隙, 使主尺另一侧面贴于尺框内壁。 Tightening the adjustment screw 19 or 26 may be locked in the main scale feet box, also be used for adjusting the gap, the other side of the main scale attached to the foot frame wall. 螺钉19和26前端的圆柱面,伸入主尺l侧面的斜向导向槽4内,可以限制主尺向其上方非正常上升,即对主尺起保护作用,又可保证主尺1上的定栅2和显示器23位置正确。 Screw 19 and the cylindrical surface 26 of the front end, the inner side surface extending into the main scale l oblique guide groove 4, the main scale may be limited thereto rises above the non-normal, i.e., protective effect on the main scale, but also to ensure the main scale 1 The gate 2 and a display 23 set in the correct position. 因导向槽4倾斜度与主尺1倾斜角一致,故不会妨碍主尺1纵向移动时向上升或下降。 4 due to the inclination coincides with the inclination angle of the main scale 1 guide groove, it does not interfere with the main scale 1 is moved longitudinally to rise or fall.

准备测量时,新尺以各导向件、面与主尺两侧面的精密配合精度、可确保主尺在斜面导轨18上的运动质量。 When ready to measure a new scale to the guide member, a main surface and side surfaces with precision accuracy of the scale, the main scale to ensure that the guide rail 18 on the inclined surface of the moving mass. 以下演示在工作台上测量已加工好的零件。 The following table demonstrates measure has been processed parts. 设被测量工件直径小于①10,适合图l示例尺0-10mm量爪面测量。 Is smaller than the diameter of the workpiece is provided ①10 measured, for example in FIG. L foot surface measuring jaws 0-10mm.

以左手食指或中指托住尺框6后面,拇指捏住17附近,右手拇指和食指捏住主尺1隔热件24,主尺校零后向后拉,将零件立放。 In his left index or middle finger hold back frame 6 feet, pinch near the thumb 17, the right thumb and forefinger and a heat insulating member 24 of the main scale, the main scale after the zero correction is pulled back, the parts will stand up. 首先将0-lOmm量爪面及导向板7侧面挨着零件表面,右手推动主尺1,使主尺向左前方纵向移动,于是主尺上平面3在纵向位移中上升逐渐接近工件。 7 first side surface of the 0-lOmm jaws and the guide plate next to the part surface, the right-hand push scale 1, so that the left front longitudinal movement of the main scale, so the plane of the main scale 3 is gradually increased to approach the workpiece in the longitudinal displacement. 接近工件时,速度减缓,右手略感阻力增大,即停止推动主尺1。 When close to the workpiece, slowed down, right resistance increases somewhat, i.e. stop pushing the main scale 1. 该阻力表明主尺上平面和尺框量爪面均已接触零件被测表面。 This resistance indicates that the main scale and the plane of the frame feet are in contact with the part surface Jaws measured surface. 该微小阻力即为测量力。 The force measured is the resistance of a minute. 此时可直接阅读显示器得零件测量值。 At this time, the part can be directly obtained measurement reading display. 数字显示器编程方法如前所述,不再赘述。 Digital display programming method as described above, will not be repeated.

测平面类零件时,更不允许用力过大,以免量爪面与零件平面间出现自锁现象。 When measuring plane type parts, but does not allow excessive force to avoid the phenomenon of self-locking between the jaws with the part surface plane appears.

在机床上,直接测量被加工工件时极为方便。 On the machine, the direct measurement of the workpiece is very convenient. 如:在外圆磨床测量两顶针间装夹的①20-①30轴时,可将该尺20-30咖量爪面直接搭挂在轴的上表面上,左手扶尺框将尺尾向上翘起。 Such as: When ①20-①30 axis of cylindrical grinding machines measured between the two centers of the clamping, the amount of coffee may be the 20-30 foot hooked jaw faces directly on the upper surface of the shaft, the left foot end of the frame supporting the foot upward tilt. 当主尺1处在与地平面夹角为20。 When the main scale 1 and at an angle to the plane 20. 左右时, 右手推动主尺,使主尺上平面至离工件下表面不远处,然后松开主尺尾部任其靠自重产生的下滑分力,克服与尺框斜面导轨之间的静摩擦力后,继续前进,可自动接触被测工件的下表面。 When the left and right, the right hand moves the main scale, the main scale to the planar surface of the workpiece, not far from, the main scale and then release the tail against any decline in its own weight of component force, overcome the static friction between the feet and the frame rail inclined surface , move, automatically contacting the lower surface of the workpiece. 如此操作测量力会十分微小,测量更精确。 Doing so will be very small measuring force, more accurate measurements.

按示例最后一种方法使用该类尺,其测量力可随尺尾向上翘起角度大小随心所欲地控制。 Scale use of such a method according to the last example, which can measure the force upward tilt angle with the foot end of arbitrary size control. 另外,该尺在设计时已考虑到在适当位置配重,以确保该尺重心位于偏下部。 Furthermore, the foot has been taken into account in the design of the counterweight in place, to ensure that the center of gravity is biased ulnar lower portion. 这样,当尺框上量爪面搭挂在被测工件表面时,自重便基本能让上量爪面与被测工件上表面处于良好的接触状态。 In this way, when the upper foot surface frame hooked jaws on the workpiece surface under test, the weight will make the surface substantially in a good contact surface on the jaws and the workpiece. 而尺尾上翘,可用主尺下滑分力,同时使主尺上平面以自动追踪消隙的方式完成与工件下表面良好接触的过程。 Upturned tail and feet, available main component scale decline, while the upper plane of the main scale to automatically track anti-backlash manner to complete the process under good contact with the surface of the workpiece. 这些均对高精度测量十分有利,也有利于长期保持该尺的精密。 These are very favorable for high-precision measurement, but also conducive to the long-term scale precision. 该尺的这种使用方法,有利于我国机械制造业一线车间运用,直接在多类别普通机床和数控机床上进行精密测量外圆类工件。 The ruler of this use, in favor of the first-line use of workshop machinery manufacturing, precision measurement cylindrical workpieces directly on the multi-class general machine tools and CNC machine tools. 对提高测量精度、 提高产品质量、降低生产成本和减少用于测量的辅助时间均有现实意义。 To improve the measurement accuracy, improve product quality, reduce production costs and reduce the auxiliary time for measurement has practical significance.

该尺保养方法和注意事项均按现有电子数显卡尺要求执行。 The foot care and precautions are by existing electronic digital calipers required to perform.

特别注意事项: special attention items:

1、 不可在非测量状态时将该尺头部即尺框量爪朝下倒拿。 1, i.e. not the feet of the head-foot block jaws fell down to take in the non-measurement state.

2、 只有在用调整螺钉锁紧主尺时,才允许手握尺框倒拿该尺。 2, only when the adjustment screw lock with the main scale, hand-foot frame is allowed to take down the scale.

3、 主尺上平面接近被测表面时,动作要慢,施加的测量力要尽量小。 3, the main scale on a plane close to the measured surface, move slowly, measuring the force applied as small as possible. 以下叙述本发明的电子数显卡尺的读数原理。 The following describes the principle of an Electronic Digital Caliper readings of the present invention.

以图1电子数显示例尺为例,主尺倾斜面倾斜角度sinct =0. 1,所以当主尺在倾斜导轨上移动时,主尺上平面与尺框上量爪面的垂直距离,等于显示器与定栅的实际相对位移量乘sinci。 Electronically displaying the number of embodiment of Figure 1 foot, for example, the main scale slanted surface sinct = 0. 1, when the main scale moves on the inclined rails, the main scale on the jaws face on a plane scale frame vertical distance equal to the display and the relative amount of actual displacement given gate multiply sinci. 测量时主尺上平面与尺框上量爪面的垂直距离就是零件的实测值。 The vertical distance from the main scale surface of the jaws on a plane foot part frame is found when measured.

每次测量零件之前需要校零(即清零)。 Every school needs to zero before measuring part (ie cleared). 方法举例:如使用图l示例尺, 使主尺1上平面3与0-10mm量爪面在正常手感测力下称无隙接触状态时,按N0、 ZERO按钮,使显示器23清零后,再向后拉动主尺l进入待测状态。 Method Example: When used as an example in FIG. L foot, the upper plane of the main scale 3 and a 0-10mm gap jaws surface contact state, said non-normal hand dynamometer, according to N0, ZERO button, so that the display 23 is cleared, after pulling the main scale l again into the state under test.

综上所述,本发明的电子数显卡尺,不但可读值精确、示值误差小,且设计原理独特,具有坚固耐用、结构简单、造价低、测量精准迅速、在其测量范围内具有全量程测微功能等优点。 In summary, the number of electrons present invention calipers, accurate values ​​of read only, indication error is small, and the unique design principles, with a durable, simple structure, low cost, rapid accurate measurement, having a measuring range within the full micrometer scale features and other advantages. 仅将如图1示例基础类型的规格品种系列化后,即完全可以取代现有普通千分尺和示值误差为土0.002mm的杠杆千分尺、微米千分尺等,直接运用于机械制造一线车间进行精密工件测量或检验。 Only after an exemplary basic types FIG varieties series, i.e. fully replace the existing ordinary micrometer and error shown Soil 0.002mm lever micrometer, micron micrometer, etc., directly applied mechanical manufacturing line shop precision workpiece measurement or inspection. 而本发明包含的斜角的正弦函数值为0.01、 0.001等更高精确度的电 And the present invention comprises a bevel sine function value is 0.01, the electrical and other higher accuracy 0.001
