Clamping module i.e. jigs, for machining of workpieces, has compression spring biasing between jackbolt and jaw in clamping direction, where clamping jaw stalks through spring force automatically in event of reduction in clamping force

摘要

The module i.e. jigs, has a base body (1), and a clamping jaw (2) that is adjustable relative to the base body. A jackbolt (3) or socket-head cap screw is screwed in the clamping jaw. A compression spring (14) biases between the jackbolt and the jaw in a clamping direction. The clamping jaw stalks through the spring force automatically in the event of reduction in clamping force. The clamping jaw is displaceable in the base body on a horizontal supporting surface (17). The spring is provided between a screw head (8) and a supporting disk.
