摘要: 本发明涉及夹具,具体地说是一种适用于工件外表面为旋转体的螺纹拧紧用夹紧装置,包括气缸、第一、二连杆及上、下夹紧块,气缸安装于气缸支座上,气缸连杆的一端与气缸输出端相连接,另一端通过销轴分别与第一、二连杆的一端连接;下夹紧块通过销轴与第一连杆的另一端连动,第二连杆的另一端铰接于固定座上;气缸铰接于气缸支座上,气缸支座安装在机架上;上夹紧块固定在机架上,下夹紧块相对于上夹紧块可上下往复运动;固定座安装在机架上;上、下夹紧块的夹紧部设有凹槽。本发明夹紧力大,采用连杆增力结构,使用缸径较小的驱动气缸即可实现较大的夹紧力,工件夹持牢固可靠;节省操作空间、场地;体积小、重量轻,制造成本低。
英文摘要: The invention relates to a clamp, in particular to a clamping device which is applicable for a rotation body with external surfaces of rotating body and used for screwing threads the clamping device comprises a cylinder, a first connecting rod, a second connecting rod, an upper clamping block and a lower clamping block the cylinder is arranged on a cylinder supporter one end of the cylinder connecting rod is connected with the output end of the cylinder and the other end thereof is respectively connected with one end of the first connecting rod and the second connecting rod by a pin shaft the lower clamping block is connected with the other end of the first connecting rod by the pin shaft the other end of the second connecting rod is pivotally connected on the fixed base the cylinder is pivotally connected on the cylinder supporter the cylinder supporter is arranged on a frame the upper clamping block is fixed on the frame the lower clamping block can reciprocate upwards and downwards correspondingly to the upper clamping block the fixed base is arranged on the frame the clamping parts of the upper clamping block and the lower clamping block are respectively provided with a concave trough the clamping device has large clamping force, uses a connecting rod reinforcement mechanism and the driving cylinder with small diameter so as to realize large clamping force, firmly and reliably clamps the workpiece, saves the operation space and site, and has small volume, light weight and low manufacturing cost.
