Description
技术领域technical field
本实用新型涉及机械设备测量工具领域，具体是可调测量量具。The utility model relates to the field of measuring tools for mechanical equipment, in particular to an adjustable measuring tool.
背景技术Background technique
机械设置的零件或者工件在制造过程中如果存在测量误差，会使设备装配困难或装配质量降低，直接影响整机的性能，降低设备的使用寿命。目前机械设备行业零部件和工件的测量工具和方法主要有以下几种：If there is a measurement error in the manufacturing process of the parts or workpieces set by the machine, it will make the assembly of the equipment difficult or reduce the quality of the assembly, which will directly affect the performance of the whole machine and reduce the service life of the equipment. At present, there are mainly the following types of measuring tools and methods for parts and workpieces in the machinery and equipment industry:
1)三坐标测量机测量：此方法测量能准确测量零件尺寸，判断是否合格，但这种检验方法成本高，加工现场不易操作。1) Three-coordinate measuring machine measurement: This method can accurately measure the size of the part and judge whether it is qualified, but this inspection method is costly and difficult to operate on the processing site.
2)卡规、卡板测量：对于较大尺寸测量时难以掌握中心，测量困难。此方法测量标准条件及检验人员的技术水平要求较高，工作条件温度为20℃，测力为0，在实际生产中很难满足使用要求。2) Measurement of snap gauges and card boards: It is difficult to grasp the center when measuring larger sizes, and it is difficult to measure. This method requires relatively high measurement standard conditions and the technical level of the inspectors. The working temperature is 20°C and the measuring force is 0. It is difficult to meet the requirements in actual production.
3)内径量表、千分尺测量：此方法测量精度高，使用方便，但测量止口深度较小时，表脚及尺架位置尺寸较大，与止口台阶面相互干涉，无法对工件进行测量。3) Inner diameter gauge and micrometer measurement: This method has high measurement accuracy and is easy to use, but when the depth of the measuring notch is small, the position of the meter foot and the ruler frame are relatively large, and interfere with the step surface of the notch, making it impossible to measure the workpiece.
4)游标卡尺测量：此方法使用方便，应用广泛，但测量精度相对较低，特别尺寸较大工件。在实际工作中，测量尺寸较大，精度要求较高零件时，较难掌握尺寸精准度，并且此量具对测量人员的技术水平要求较高，因此此量具较适合对基本尺寸进行测量。4) Vernier caliper measurement: This method is easy to use and widely used, but the measurement accuracy is relatively low, especially for large workpieces. In actual work, when measuring parts with large dimensions and high precision requirements, it is difficult to grasp the dimensional accuracy, and this measuring tool requires high technical level of the measuring personnel, so this measuring tool is more suitable for measuring basic dimensions.
基于现有检测方法都存在各种自身局限性，同时有些机械设备的工件内、外径止口(通常设计用来定位的圆柱内孔及外圆凸肩俗称止口)较浅测量相对困难，因此有待开发一种结构简单、使用方便测量误差小的测量工具，同时可测量内、外径止口较浅的工件的测量工具。Based on the existing detection methods, there are various limitations. At the same time, it is relatively difficult to measure the inner and outer diameters of some mechanical equipment (the cylindrical inner hole and the outer circular shoulder commonly known as the spigot designed for positioning). Therefore, there is a need to develop a measuring tool that is simple in structure, easy to use and small in measurement error, and can measure workpieces with shallow inner and outer diameter stops at the same time.
