Definitions
- the subject invention is a self-centering vise designed for clamping workpieces with large dimensions and high cutting forces, for workpieces exposed to deformations, clamping logs, clamping workpieces with trapezoidal and rectangular cross-sections, of existing symmetry surface.
- the matter of invention is a self-centering modular vise, where power transmission takes place via square wrench and additional self-centering compensating module.
- Drive of the jaw movement is perpendicular to the movement direction of jaw clamping/unclamping.
- a minimum of two independent modules are driven via centrally applied torque.
- the swiveling jaw inserts allow for vertical adjustment of the clamping surface to the clamped workpiece.
- the advantage of the solution according to invention is a compact design that allows clamping in prisms without receiving degrees of freedom (compensation), while maintaining the position of the symmetry surface. Further advantages are: high clamping force obtained via gear drive ratio unit, self-locking drive unit that allows for wrench and self-centering module removal without force loss, possibility of simple extension of the system and increase of the clamping range and interchangeable jaws inserts that allow to adapt to specific shapes, including shaft-type components (without support) in prism inserts.
- the components of a self-centering vise consist of: clamping jaw module 1, gear drive ratio unit 2, solid jaw 3, square wrench 4, swiveling jaw insert 5, interchangeable jaw insert 6, tension bar 7, drawbar 8, locking slot 9 and self-centering compensating module 10.
- Torque from the square wrench on the linear gear is transmitted to the toothed gear that cooperates with toothed bar, so-called gear rack.
- the rotary movement of the pinion is converted into sliding movement transmitted via gear rack carried out in leading channels, beyond self-centering compensating module, where via made hooks the force is transmitted linearly to tension bars, connected on the toothed side with pinions in the left and right clamping jaws.
- the jaws are an integral multi-unit parts of the gear drive ratio, that convert rotary movement of the pinion to linear movement of the solid jaws, directed towards the opposite jaw. The movement takes place until the maximum clamping force is obtained.
- the swinging insert ensures proper jaw alignment to the shape of the workpiece side walls.
- the workpiece When using locking slot, the workpiece is clamped once it is set in driving axis on the symmetry surface of the clamped workpiece. When locking slot is removed the clamping takes place with compensation movement of the jaw, which as a first grips the workpiece. After clamping of the workpiece in clamping jaws the wrench movement in the direction opposite to clamping direction within a few degrees releases compensating self-centering module, that can be postponed. The force is maintained by self-locking drive multi-units. The wrench movement in a range of above-mentioned several degrees in direction opposite to clamping direction causes unclamping of the workpiece, and then outward moving of the jaws.
