Abstract
A workholding fixture used by a multi-wire cutting machine consists of a primary connection socket and a secondary connection socket, a primary connection sheet and a secondary connection sheet. The primary connection socket and the primary connection sheet are fixed by bolts in a plane connection and the secondary connection socket and the secondary connection sheet are fixed by positioning bolts in a plane connection. The present invention is characterized in that the shape of a positioning bolt hole of the secondary connection socket for holding the positioning bolt is different such as the long groove shape and the oval shape. Compared with the prior art, the present invention changes the shape of the bolt hole of the secondary connection socket for holding the positioning bolt; therefore, when the position of the secondary workpiece is inconsistent with the position of the primary workpiece after the primary workpiece is fixed and positioned, only the positioning bolt is unscrewed and the oval hole is used for adjusting the front and rear positions of the secondary connection sheet slightly, thereby carrying out fixing. The workholding fixture overcomes the defects that the shape of the bolt hole of the secondary connection socket for holding the positioning bolt in the prior art is round and the workpiece can not be adjusted forwards or backwards.
