Fast screw clamping mechanism, comprises base, screw, jaw plate, moved jaw, compound screw mandrel, end cap, bearing pin, adjusting pad, pin, composite screws, nut, handle.Described base assembles jaw plate by screw, described moved jaw is also equipped with jaw plate, moved jaw also passes through bearing pin, pin, adjusting pad connects with compound screw mandrel, described compound screw mandrel one end connects with moved jaw, the other end is designed to helix and the combination of the axial line of rabbet joint, compound screw mandrel is by being fixed on the end cap supporting on base, on end cap, the composite screws end of radial assembling coordinates with compound screw rod spiral groove, described end cap is fixed by screws on base, composite screws fastening nuts on end cap, rotate composite filament boom end handle, the helix of compound screw mandrel and composite screws form screw pair and move, compound screw mandrel drive moved jaw does folder purple and unclamps motion, after composite screws enters the compound screw mandrel cylindrical axial direct line of rabbet joint, compound screw mandrel drives moved jaw to do fast advance and retreat motion.
Description
Technical field
The utility model relates to a kind of machine clamping mechanism, belongs to mechanical driving device, is mainly used in the Quick-clamped in mechanical clamp.
Background technology
In mechanical clamp mechanism, usually adopt machinery or Hydraulic Clamping Mechanism, for non-cushioned clamping application based on mechanical type, clamping transmission mechanism often adopts trapezoid spiral secondary, but when needing Long Distances to make a concession after unclamping, screw pair is rotated comparatively slow, and efficiency is low.
Summary of the invention
For better realizing Quick-clamped in mechanical clamp and Long Distances is made a concession, the utility model provides a kind of fast screw clamping mechanism, not only has the performance of normal spiral clamp system, can also realize the quick yielding function of Long Distances.
The technical solution of the utility model is: for the fast screw clamping mechanism in mechanical clamp, comprises base, screw, jaw plate, moved jaw, compound screw mandrel, end cap, bearing pin, adjusting pad, pin, composite screws, nut, handle.Described base is equipped with jaw plate by screw, described moved jaw is also equipped with jaw plate, moved jaw is also connected with compound screw mandrel by bearing pin, pin, adjusting pad, described compound screw mandrel one end connects with moved jaw, the other end is designed to the combination of helix and the axial line of rabbet joint, compound screw mandrel is by being fixed on the end cap supporting on base, on end cap, the composite screws end of radial assembling coordinates with compound screw rod spiral groove, described end cap is fixed by screws on base, the composite screws fastening nuts on end cap.
During application, rotate composite filament boom end handle, the helix of compound screw mandrel and composite screws form screw pair and move, and compound screw mandrel drives moved jaw to do motion of retreating at a slow speed, after composite screws enters the compound screw mandrel cylindrical axial direct line of rabbet joint, compound screw mandrel drives moved jaw to do fast advance and retreat motion.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model fast screw clamping mechanism schematic diagram.
Detailed description of the invention
See accompanying drawing, the utility model provides a kind of fast screw clamping mechanism, comprises base 1, screw 2, jaw plate 3, jaw plate 4, moved jaw 5, compound screw mandrel 6, screw 7, end cap 8, bearing pin 9, adjusting pad 10, pin 11, composite screws 12, nut 13, handle 14.Described base 1 is equipped with jaw plate 3 by screw 2, described moved jaw 5 is also equipped with jaw plate 4, moved jaw 5 is also by bearing pin 9, pin 11, adjusting pad 10 connects with compound screw mandrel 6, described compound screw mandrel 6 one end connects with moved jaw 5, the other end is designed to the combination of helix and the axial line of rabbet joint, compound screw mandrel 6 is supported by the end cap 8 be fixed on base 1, on end cap 8, composite screws 12 end of radial assembling coordinates with compound screw mandrel 6 helicla flute, described end cap 8 is fixed on base 1 by screw 7, composite screws 12 on end cap 8 is fastening with nut 13.
Described handle 14 rotates compound screw mandrel 6, the helix of compound screw mandrel 6 and composite screws 12 form screw pair and move, compound screw mandrel 6 drives moved jaw 5 to do clamping and release campaign at a slow speed, after composite screws 12 enters the compound screw mandrel 6 cylindrical axial direct line of rabbet joint, compound screw mandrel 6 drives moved jaw 5 to do fast advance and retreat motion.
