The invention relates to a roll collar hoisting clamp, which belongs to the technical field of roll collar processing, and comprises a first hoisting arm and a second hoisting arm which are mutually hinged into an X shape, hoisting parts are formed at two opposite ends of the first hoisting arm and the second hoisting arm, and the upper ends of the first hoisting arm and the second hoisting arm are connected through a first driving piece; the lower end of the first hoisting arm and the lower end of the second hoisting arm are each provided with a first clamping part which vertically extends downwards, two second clamping parts used for clamping the inner ring of the roll collar workpiece are arranged between the two first clamping parts, and the two second clamping parts are connected with the first hoisting arm and the second hoisting arm through two sets of second driving pieces correspondingly. The lifting device has the advantages that holding force can be applied to the roll collar workpiece from the inner ring side and the outer ring side of the roll collar workpiece at the same time, the force borne by the inner ring and the outer ring of the roll collar workpiece can be balanced, and an unsintered roll collar blank cannot be damaged when being lifted.
本发明涉及一种辊环吊装夹具,属于辊环加工技术领域,它包括相互铰接成X形的第一吊装臂和第二吊装臂,所述第一吊装臂和第二吊装臂相对的两端形成有吊装部,所述第一吊装臂和第二吊装臂的上端通过第一驱动件连接,所述第一吊装臂和第二吊装臂下端分别形成有竖直向下延伸的第一夹紧部,两个所述第一夹紧部之间设有两个用于夹持辊环工件内圈的第二夹紧部,两个所述第二夹紧部通过两组第二驱动件分别与所述第一吊装臂、第二吊装臂连接。本发明具有能够从辊环工件内圈一侧和外圈一侧同时向辊环工件施加抱紧力,能够平衡辊环工件内外圈受到的力,使得吊装未烧结的辊环毛胚时不会对其造成损坏等优点。
