Tubular workpiece clamping device - comprises two blocks connected by threaded spindle and coupled to two-armed levers in frame with clamping jaws

摘要

The clamping device has two threaded blocks (16, 18) connected to each other by a threaded spindle (20) with counter threaded parts (22, 24'). Thus, by rotation of the spindle, the blocks, can be moved relatively towards or away from each other. One block (16) is connected to a first tw two-armed lever (13) and also with the end of a thrust rod (28) whose other end is connected to a second two-armed lever (15). The levers (13, 15) are located in a common frame, one of the end of which is formed as clamping jaws (34, 44).
