技术领域technical field
本实用新型涉及一种外圆跳动检测设备,具体的说是一种管件外圆径跳检测装置。The utility model relates to an outer circle runout detection device, in particular to a pipe fitting outer circle runout detection device.
背景技术Background technique
各种管件及其加工件在工业生产中占有相当的比重,而管件的外圆径跳是检验管件质量的重要指标。在工业现场目前外圆径跳的检测大都采用传统的接触式检测方法,该方法采用百分表或径跳检测仪进行外圆径跳检测。这种检测方式的缺点主要有:1.每个检测件需要在圆周上取多个点,每个点的值需要靠操作人员从表针的指示位置读出,读值的过程因人而异,存在人为的偏差;2.每检测一个工件都需要对检测仪表进行调整,耗时长,效率低,所以只能是批量抽检,不适用于逐个检验;3.由于每个采样点都是静态检测,所以检测的径跳值并不能反映管件在实际运转过程中的径跳量。Various pipe fittings and their processed parts occupy a considerable proportion in industrial production, and the outer diameter runout of pipe fittings is an important indicator for testing the quality of pipe fittings. At present, most of the detection of outer circle runout in the industrial field adopts the traditional contact detection method, which uses a dial indicator or a radial runout detector to detect the outer circle runout. The main disadvantages of this detection method are: 1. Each detection piece needs to take multiple points on the circumference, and the value of each point needs to be read by the operator from the indicated position of the watch needle. The process of reading the value varies from person to person. There are man-made deviations; 2. Every time a workpiece is detected, the detection instrument needs to be adjusted, which takes a long time and is inefficient, so it can only be a batch sampling inspection, not suitable for one-by-one inspection; 3. Since each sampling point is a static inspection, Therefore, the detected radial runout value does not reflect the radial runout of the pipe fittings during actual operation.
在工业自动化生产装配的大趋式下,对产成品都要求进行在线检测,所以传统的检测方法不再适用于自动化生产的要求。Under the general trend of industrial automation production and assembly, on-line testing is required for finished products, so traditional testing methods are no longer suitable for the requirements of automated production.
