Small part comparison detection clamping device and method

The invention discloses a small part comparison detection clamping device. A standard part and a product are clamped independently, a product clamping device ascends and descends vertically, a standard part clamping device ascends and descends in an inclined sliding mode, when the standard part needs to be calibrated, the product clamping device moves downwards to avoid, the standard part clamping device moves upwards, automatic switching and accurate positioning of a detected product and a comparison standard product are realized, and a probe and a loading and unloading manipulator are effectively avoided when the product or a standard part is detected. The invention further discloses a small part comparison detection clamping method based on the small part comparison detection clamping device. 本发明公开了一种小型零件比对检测装夹装置，标准件和产品独立夹装，其中产品夹装装置竖直升降，标准件夹装装置斜滑式升降，当需要进行标准件校准的时候，产品夹装装置下移避让，标准件装夹装置上移，实现了检测产品与比对标准产品自动切换及精准定位，且在产品或标准件检测时有效避让测针及上下料机械手；本发明还公开了一种基于小型零件比对检测装夹装置的小型零件比对检测装夹方法。
