Paired clamping and positioning device for L-shaped workpieces

According to the paired clamping and positioning device for the L-shaped workpieces, the two positioning blocks are arranged on the two sides of the vertical plate correspondingly, and the circular positioning pin and the edge cutting positioning pin are arranged on the two positioning blocks on the same side correspondingly, so that the two L-shaped workpieces can be positioned on the two sides of the vertical plate in the mode that two pins are arranged on one face, and the matching precision is guaranteed. The two L-shaped workpieces can be clamped in the forward direction or in the reverse direction, the size, flatness, perpendicularity and other form and position precision of the two L-shaped workpieces can be guaranteed at the same time, the curve contour characteristics of V-shaped grooves or semicircular grooves and the like of the two L-shaped workpieces can be machined at the same time, the loading and unloading frequency is reduced, and the machining efficiency is improved.
