ABSTRACT:
A spring vice (56) for tensioning coil springs, which have a spindle drive (59, 61), which has approximately wedge-shaped radial fingers (64, 65, 66) at one of its ends and a support cylinder (60) with a contact element at its other end. Two pressure plates (57, 58) with a passage opening (77, 87), through which the spindle drive (59, 61) can be passed, are used to tension a coil spring. In the mounted state, the radial fingers (64, 65, 66) of the spindle drive (59, 61) can be brought into a nonrotatable pulling connection with locking recesses (81, 82, 83) of the first pressure plate (57), while the second pressure plate (58) without locking recesses is supported axially at the contact element of the support cylinder (60) of the spindle drive (59, 61) for tensioning the coil spring. To increase the safety of operation, provisions are made for the contact element of the support cylinder to have support fingers (72, 73, 74), whose number corresponds to the number of the radial fingers (64, 65, 66). The second pressure plate (58) has a design substantially identical to that of the first pressure plate (57) and it likewise has locking recesses (91, 92, 93). Thus, the first and second pressure plates (57 and 58) with their locking recesses (81, 82, 83, 91, 92, 93) of their respective passage openings (77, 87) can be caused to engage optionally the support fingers (72, 73, 74) of the support cylinder (60) or the radial fingers (64, 65, 66) of the spindle drive (59, 61).
