Technical Problem
[0002]疲劳检测机又名疲劳试验机，可用于测定金属物件在室温状态下的拉伸、压缩、或其它压力动作下的疲劳性能，而球头高低温疲劳检测机则是一种将球头置放于温控箱内进行疲劳检测的设备，传统的球头高低温疲劳检测机在检测球头疲劳性能时，由于球头形状的特殊性，需要在温控箱内设置极为复杂的固定机构才能够对球头进行固定，导致结构臃肿化，极占温控箱内部的空间，且在进行疲劳性能检测时，只能施加一个方向的力在球头上，而在球头实际使用过程中，施加于球头上的力更为复杂，往往是两种以上的力施加于球头上，比如推力以及摆动的力，因此单一检测球头在承受一个方向的力时的变形情况，难以准确检测出球头的实际疲劳性能，无法保证检测结果的精准性
Benefits of technology
[0016]与现有技术相比，采用本发明结构的球头高低温疲劳检测机只需通过球头座上的球型槽对球头位置进行定位，然后再利用第二安装板与球笼压紧块之间的配合便能够将球头进行固定，整个固定结构极为简单，使其不会占有温控箱内的温控腔室的过多空间，便于部件的装配，且若是测试不同型号的球头，只需将球头座更换成具有与球头相匹配的球型槽的球头座型号即可，有效增加适用范围，而径向检测机构能够同时在球头上施加径向推力以及转动力，轴向检测机构能够同时在球头上施加轴向推力以及摆动的力，四种不同的力皆可施加于球头进行检测，从而从多方面数据有效分析检测出球头的疲劳性能，最大程度上保证检测数据的精准性。
