Tight clamping structure in squaring machine silicon rod top

The utility model discloses a tight clamping structure in squaring machine silicon rod top, include that the whole that formation is extended relatively to two the mount pads upper end levels that are located is horizontal columniform clamping part, its characterized in that, the clamping part is including two main grip blocks that are used for centre gripping silicon rod both ends middle parts position, still including arranging that at least four rim charge grip blocks outside is provided with rim charge fixture and is used for driving the rim charge grip block moves the centre gripping of realizing the rim charge in main grip block eight rim charge grip blocks that are used for four rim charge both ends of centre gripping silicon rod all around. The utility model has the advantages of simple structure can do benefit to the unloading of the back material of evolution cutting more, produces when avoiding the rim charge cutting to drop and collapses limit and collision loss. 本实用新型公开了种开方机硅棒顶紧夹持结构，包括位于两个安装座上端水平
