摘要: 本实用新型涉及夹具,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。本实用新型夹紧力大,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 utility model relates to a jig, concretely a clamping device applied to the external surface of a workpiece for screwing up the screw thread of a rolling body, which comprises a cylinder, a first connecting rod and a second connecting rod and an upper clamping block and a lower clamping block, the cylinder is arranged on a cylinder saddle, one end of a cylinder connecting rod is connected with the output end of the cylinder, and the other end thereof is connected with one end of the first and the second connecting rods respectively by a pin shaft the lower clamping block is in continuous action with the other end of the first connecting rod by a pin shaft, and the other end of the second connecting rod is hinge-jointed on a fixed seat the cylinder is hinge-jointed on the cylinder saddle, and the cylinder saddle is disposed on the machine frame the upper clamping block is fixed on the machine frame, and the lower clamping block can reciprocate up and down relative to the upper clamping block the fixed seat is mounted on the machine frame and the clamping parts of the upper and the lower clamping blocks are provided with grooves. The utility model has big clamping force which can be realized by adopting the connecting rod boosting structure and using a driving cylinder with a rather small cylinder diameter, and the clamping to the workpiece is firm and reliable and the utility model has advantages of operation space and site saving small size, light weight and low manufacturing cost.
