Bakelite handle self-locking clamp

Bakelite handle self-locking clamp is mainly used for fastening and drilling template positioning of the workpiece. Device specific folder on the drilling template , loading and unloading of the workpiece is extremely convenient. Bakelite handle 12 fixed by screws specific folder on the drilling template , and be careful not to be too tight to ensure that adjustments elastic rubber pad .
        Bakelite handle its operation principle is: When drilling template 3 Align the baseline on the workpiece 2 , lever handle 9 , due to the role of the shaft 7 , workpiece clamping lever a rising pressed 2 . Since bakelite handle to drive fork 8 position beyond the limit stops on the base ( the base is processed by a 75 " slant to locate ) , so can self-locking , without having to add another spring device .
        6 chuck fitted under the base and bakelite handle rubber pad , so that there is some flexibility. If you press the icon size , ie eccentricity d two 20 mm , positioning the slope angle of State = 75. , The rubber pad from the limit position to the elastic gripping distance l by the following formula : L = dd x sin = 20 (1-sin75 ° ) = 0.68 mm .
        So long as this bakelite handle fixture according to the thickness of the workpiece and drilling template , select the appropriate size of a clamping lever , the appropriate adjustments to the thickness of bakelite handles like Pidian . That can get a larger clamping force. Use the bakelite handle workpiece clamping fixture can shorten the processing time and ensure accuracy , achieved remarkable results in the medium and small batch production .
