Further, the U-shaped groove frame adopts a hollow structure.

Furthermore, a reinforcing rib connected with the end face of the disc is arranged on the outer side of the U-shaped groove frame.

Furthermore, the vertical rod penetrates through pin holes in the upper end face and the lower end face of the U-shaped connecting piece.

The utility model has the advantages that:

the utility model provides a quick clamping frock for U-shaped connecting piece, its simple structure, novelty, compensate the limitation of ordinary lathe chuck jack catch, solved the difficult problem that general sleeping carriage processing four-jaw chuck can't the clamping location, realize from unable clamping location to quick clamping quick location, make the part that ordinary jack catch can't the clamping become can the clamping; the processing range of lathe equipment is expanded; the problem that the irregular rotary body and parts with special shapes cannot be clamped by turning is solved. The utilization rate of the machine tool is improved, the processing cost is reduced, and the production efficiency is improved.
