Abstract
A hook-shaped clamping and fixing device is used for being installed on a work platform and internally fixing an open workpiece provided with a step inside. The work platform is provided with a plurality of T-shaped tables at intervals in parallel. The hook-shaped clamping and fixing device comprises a base, a hook-shaped element in pivot connection with the base, a longitudinal adjusting element and a transverse adjusting element. The longitudinal adjusting element is installed at the end, corresponding to the hook-shaped element, of the base. The transverse adjusting element is installed on the base to adjust and fix the workpiece. When the longitudinal adjusting element is adjusted to move downwards, the corresponding end of the hook-shaped element rotates, and accordingly the other end of the hook-shaped element is driven to press downwards and fix the interior of the workpiece. By means of the lever principle, the required internal workpiece is fixed through the hook-shaped clamping and fixing device, operation is flexible, and the hook-shaped clamping and fixing device has the advantages of being suitable for workpieces with different apertures, good in clamping and pressing effect and the like. The transverse adjusting element of the hook-shaped clamping and fixing device further guarantees that the workpiece does not swing or wring during machining.
