Description

多节轴类产品测量装置及其使用方法Measuring device for multi-section shaft products and method of use thereof 技术领域technical field
本发明涉及一种多节轴类产品测量装置及其使用方法。The invention relates to a measuring device for multi-section shaft products and a method for using the same.
背景技术Background technique
具有多节的轴类产品广泛应用于机械***和机械加工中，例如内燃机中的曲轴和凸轮以及笔杆模具等。由于多节轴类产品的各节具有特定功能，其各节的外径和长度精度直接影响机械***寿命和机械加工品质。因此，有必要对多节轴类产品的各节外径和长度进行满足要求的测量，去除不良的多节轴类产品和反馈控制多节轴类加工工艺，保证多节轴类产品精度，确保多节轴类产品的机械***寿命和机械加工品质。Shaft products with multiple sections are widely used in mechanical systems and machining, such as crankshafts and cams in internal combustion engines and pen holder molds, etc. Since each section of multi-section shaft products has specific functions, the outer diameter and length accuracy of each section directly affect the life of the mechanical system and the quality of machining. Therefore, it is necessary to measure the outer diameter and length of each section of multi-section shaft products to meet the requirements, remove bad multi-section shaft products and feedback control the processing technology of multi-section shafts, ensure the accuracy of multi-section shaft products, and ensure Mechanical system life and machining quality of multi-section shaft products.
传统中，多节轴类产品主要使用投影测量法和像素尺寸测量法实现各节外径和长度的测量。投影测量对操作人员要求高，对产品各节的位置进行肉眼标记，通过灰度测算达到测量各节外径长度的目的。该方法测量效率低下和测量结果受人为因素影响较大，且无法实现通过测量误差分离提高测量精度，已逐渐不能满足工业界的高效、高精度的测量要求。像素测量法使用面阵CCD拍摄工件二维轮廓，通过计算任意两个特征之间像素点数量达到外径和长度测量的目的。微米级的像素点尺寸决定了像素测量只能达到10微米级的测量精度，同时在大尺寸工件测量时使用的拼接测量会进一步降低像素测量的精度。Traditionally, multi-section shaft products mainly use projection measurement and pixel size measurement to measure the outer diameter and length of each section. Projection measurement has high requirements for operators. The position of each section of the product is marked with the naked eye, and the purpose of measuring the outer diameter of each section is achieved through grayscale calculation. The measurement efficiency of this method is low and the measurement results are greatly affected by human factors, and it is impossible to improve the measurement accuracy through measurement error separation, which has gradually failed to meet the high-efficiency and high-precision measurement requirements of the industry. The pixel measurement method uses the area array CCD to capture the two-dimensional profile of the workpiece, and achieves the purpose of measuring the outer diameter and length by calculating the number of pixels between any two features. The micron-level pixel size determines that pixel measurement can only achieve a measurement accuracy of 10 micron level, and at the same time, the splicing measurement used in the measurement of large-sized workpieces will further reduce the accuracy of pixel measurement.
有鉴于此，有必要对现有的多节轴类产品测量装置予以改进，以解决上述问题。In view of this, it is necessary to improve the existing multi-section shaft product measuring device to solve the above problems.
