工厂常用氧气—乙炔火焰对小型轴类零件进行简易加热淬火，此方法的缺点之一是表面受热不匀，从而导致淬火后零件表面硬度不均匀以及变形、开裂等，为此我厂设计了一种简易淬火装置。结构如图１所示，由Ｖ型夹爪１、夹块２、夹套３、拉杆４、轴承５、１０、１５、支承板６、轴 Factory commonly used oxygen - acetylene flame on the small shaft parts for simple heating quenching, one of the shortcomings of this method is uneven surface heating, resulting in parts hardness after quenching uneven and deformation, cracking, etc., for which I designed a Simple quenching device. Structure shown in Figure 1, the V-shaped jaw 1, 2 clamps, jacket 3, the rod 4, bearing 5,10,15, 6 supporting the shaft
