Stone fixture for some products, semi-products are hollow or solid column body, this kind of product workpiece accumulation or production and processing use vertical placement, loading and unloading handling links can not hurt the end face and cylindrical surface, or there are scraps and waste products. On the market, there are commonly used stone lifting clamps and stone clamps for clamping square product workpieces. Cylindrical product workpieces can only be lifted with ropes. Let's talk about the stone fixture use need to pay attention to what problems?

　　1. Stone hanging clip and stone fixture ring body are made of thick steel plate after rolling and butt welding. The joint must be firm and welded to strengthen reinforcement plate when necessary.

　　2, stone lifting clamp, stone fixture rubber sheet can be replaced with brake belt;

　　3. Because of the limitation of friction Angle, for a class of stone lifting clamps and stone clamps, the outer diameter transition area of the clamped product workpiece is not large, otherwise there is no way to self-lock clamping. For different outer diameter specifications and models of the product workpiece need a set of different specifications and models of stone lifting clamps, stone fixtures, which can be provided to the scale of manufacturing manufacturers;

　　4, the use of parallelogram four-bar mechanism working principle and friction self-locking principle, stone lifting clamp, stone fixture can be deformed into internal fixture, that is, to tighten the product workpiece cylindrical fixture, used for special lifting places.
