标枪轴线中点圆跳动公差检测装置的研究

Research on the Axis Midpoint Circular Runout Tolerance Detection Device for Javelin

标枪轴线中点的圆跳动公差值是影响飞行质量的重要参数,研发一种标枪轴线中点圆跳动公差检测装置,以可靠、准确、快速的得出轴线中点的圆跳动公差值,控制比赛标枪质量。使用本装置时,只需将标枪装入标枪上端以及下端定位机构间并锁紧弹性锥套,移动调节滑块到标枪中点位置,调整圆跳动测量设备探针与标枪表面接触,旋转标枪即可测得标枪轴线中点的圆跳动量。实验证明,本装置使用方法比传统方法更简单,测量结果设备误差和操作误差小,重复性高,可满足多规格标的测量要求。

To javelin axis midpoint circularrunout tolerance value is an important parameter affecting the quality of tlight, to develop a javelin axis midpoint circle runont tolerance lest device. in a reliable, accurate and fast axis of midpoint circle runou tolerance value, control the quality of the javelin. Using this device. just put the javelin in javelin between top and bottom positioning and locking elastic taper sleeve, move to adjust the slider to the javelin neutral position, adjust the circular runoul measuring equipment probe and javelin surface contact, rotate lhe javelin axis can be measured javelin midpoint eircle to beat. Experiments show that this device nsing method is simpler than the lradilional methods, the measurement error and the operation of equipment. high repeatability, can meet the measurement requirement of many specifications.
