Sinusoidal thimble seat

The utility model provides a sinusoidal thimble seat, include the sinusoidal thimble seat main part, etc. High stick and opposite vertex subassembly, fix when high stick terminal surface under the sinusoidal thimble seat main part, the opposite vertex subassembly is fixed the up end of sinusoidal thimble seat main part, there are two, two when high stick when high excellent parallel arrangement, two be close to when high stick the both ends of sinusoidal thimble seat main part, be circular when high excellent cross section, the opposite vertex subassembly corresponds the setting in pairs. This technical scheme is more direct reachs conical part's allowance, has improved measuring efficiency to the measuring accuracy has still been guaranteed simultaneously to the efficiency of improving production. 种正弦顶针座，包括正弦顶针座主体、等高棒和对顶组件，所述等高棒固定在所述正弦顶针座主体下端面，所述对顶组件固定在所述正弦顶针座主体的上端面；所述等高棒有两根，两根所述等高棒平行设置，两根所述等高棒靠近所述正弦顶针座主体的两端，所述等高棒横截面为圆形；所述对顶组件成对对应设置。本技术方案比较直接的得出锥形件的加工余量，提高了测量的效率，从而提高生产的效率，同时还保证了测量的准确性。
