A universal jig is provided for clamping wind turbine blades. The jig has a rectangle-like shape forming a space for clamping a blade at the blade root or the blade body. The jig comprises a set of vertically-moving parts; a set of horizontally-moving parts; a plurality of adjusted pads; and a plurality of positioning parts. The vertically-moving parts comprise two upper connecting posts and two lower connecting posts sheathed with each other separately to form two length sides of the jig. The horizontally-moving parts comprise two left connecting posts and two right connecting posts. The adjusted pads are locked on the left and the right connecting posts. The positioning parts are locked at the upper and the lower connecting posts of the length sides of the jig and are locked at the left and the right connecting posts of the width sides of the jig.

The invention relates to an automatic precision worktop for drilling without deviation for cylindrical workpiece which includes a loading device, a drilling device and an uploading device. The loading device includes a first sliding rail disposed horizontally on the side of the drilling device, a loading plate disposed on the first sliding rail and slidingly engaged with the first sliding rail, and two first linkages driving the loading plate to slide on the first sliding rail. Each linkage includes a link mechanism, and a driving motor that drives movement of the link mechanism. Two sides of the loading plate are respectively provided with a third sliding rail slidably engaged with two link mechanisms. The drilling device includes a clamping device, a drilling mechanism located on the side of the clamping device and a positioning mechanism slidingly engaged with the clamping device.
