Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Embodiment:
As shown in Figure 1 to Figure 2, a kind of four claw quick-locking devices, the pedestal 1 including putting workpiece, 1 bottom of pedestal is equipped with
Four support columns 2,2 bottom of support column are equipped with non-slip mat 14, and 1 upper surface of pedestal, which is fixed with, is used to support and controls drill bit 12
Drilling bit support 6,1 upper annular equidistant arrangement of pedestal is equipped with dovetail in each dovetail through slot 4 there are four dovetail through slot 4
Slot sliding block 5 can carry out suitable 5 position of dovetail groove sliding block of unrestricted choice, swallow according to the size of workpiece and the position of drilling
Stern notch sliding block 5 is equipped with first locking device fixed for workpiece, and the first locking device includes being sheathed on dovetail groove sliding block 5
Guide rod supports column 8, pass through 8 ontology of guide rod supports column and two threaded guide rod 7 disposed in parallel, guide rod supports column 8 be equipped with use
In the through-hole that threaded guide rod 7 passes through, two 7 both ends of threaded guide rod pass through one end of riveting pin 11 and a workpiece fixed block 10 respectively
The company of strand drives dovetail groove sliding block 5 close to workpiece, while adjusting threaded guide rod 7 and workpiece fixed block 10 by guide rod supports column 8
Between angle promote 10 side of workpiece fixed block and side surface of workpiece to completely attach to, workpiece fixed block 10 is close to 1 centre bit of pedestal
The surface set is equipped with silicon rubber block 13, and the frictional force that silicon rubber block 13 increases between workpiece plays protection outer surface of workpiece simultaneously
Effect, two nuts 9 cooperated with guide support column 8 are set on threaded guide rod 7, when workpiece fixed block 10 and side surface of workpiece are complete
After Full connected, tightening nut 9, double nuts structure reduces nut in drilling and falls off, and guarantees the clamping dynamics of workpiece.
