Abstract
A spanner drill chuck is characterized in that three clamping jaw holes forming a certain angle with an axial center line are uniformly distributed on a drill body, clamping jaws are arranged in the three clamping jaw holes, a nut groove is formed in the middle of the drill body, a nut is arranged on the nut groove, internal threads on the nut are meshed with external threads on the outer diameters of the three clamping jaws, an outer sleeve is arranged on the outer diameter of the nut, spanner positioning holes are uniformly distributed on the outer diameter below the drill body, a thrust bearing is arranged between the nut and the upper side of the nut groove, when the nut is driven by a spanner to rotate, the nut and the upper side plane of the nut groove are not rubbed, the rotating torque is small, the input torque of a clamping or loosening drilling tool is small, the output torque is large, the rotation is light, and the.
Description
The utility model relates to drill jig, says it is a kind of spanner drill chuck in detail.
We know, existing spanner drill chuck, even cloth and three angled jaw holes of longitudinal center line are provided with jaw in three jaw holes on the drill body, the drill body middle part is provided with the screw groove, be provided with screw in the screw groove, the internal thread on the screw is meshed with external screw thread on three jaw external diameters, and the screw external diameter is provided with overcoat, even cloth spanner locating hole on the external diameter of drill body below, spanner inserts the spanner locating hole, drives screw and rotates, and drives jaw and unclamps or clamp drilling cutters.This spanner drill chuck, owing to only be provided with screw on the screw groove, when spanner drives the screw rotation, screw and screw groove upper side plane rub, and rotating torque is big, clamp or to unclamp drilling cutters input torsion big, output torque is little, sometimes even be difficult to clamp or unclamp drilling cutters.
The purpose of this utility model, when providing a kind of spanner and driving screw and rotate, screw and screw groove upper side plane do not rub, and rotating torque is little, clamps or unclamps drilling cutters to import torsion little, and output torque is big, rotates light spanner drill chuck.
For achieving the above object, the utility model can adopt following scheme to realize:
Even cloth and three angled jaw holes of longitudinal center line on the drill body, be provided with jaw in three jaw holes, the drill body middle part is provided with the screw groove, the screw groove is provided with screw, internal thread on the screw is meshed with external screw thread on three jaw external diameters, and the screw external diameter is provided with overcoat, even cloth spanner locating hole on the external diameter of drill body below, its primary structure characteristics are to be provided with thrust bearing between screw and the screw groove upside.
The utility model is owing to be provided with thrust bearing between screw and the screw groove upside, and when spanner drove the screw rotation, screw and screw groove upper side plane did not rub, and rotating torque is little, clamps or to unclamp drilling cutters torsion little, rotates light.The utility model is applicable to various spanner drill chucks.
Description of drawings
Fig. 1 is a kind of schematic diagram of embodiment, and Fig. 2 is a kind of schematic diagram of embodiment.
Below in conjunction with accompanying drawing, the utility model is elaborated.
From 1 figure as can be seen, even cloth and three angled jaw holes of longitudinal center line on the drill body 1, be provided with jaw 2 in three jaw holes, drill body 1 middle part is provided with the screw groove, be provided with screw 5 in the screw groove, internal thread on the screw 5 is meshed with external screw thread on three jaw 2 external diameters, screw 5 external diameters are provided with overcoat 3, even cloth spanner locating hole 6 is provided with thrust bearing 4 between screw 5 and the screw groove upside on the drill body 1 below external diameter, and spanner inserts spanner locating hole 6, driving screw 5 rotates, drive jaw 2 unclamps or clamps drilling cutters, because the effect of thrust bearing 4, screw 5 does not rub with screw groove upper side plane, rotating torque is little, clamp or to unclamp drilling cutters input torsion little, output torque is big, rotates light.
From 2 figure as can be seen, even cloth and three angled jaw holes of longitudinal center line on the drill body 1, be provided with jaw 2 in three jaw holes, drill body 1 middle part is provided with the screw groove, be provided with screw 5 in the screw groove, internal thread on the screw 5 is meshed with external screw thread on three jaw 2 external diameters, screw 5 external diameters are provided with overcoat 3, and even cloth spanner locating hole 6 is provided with thrust bearing 4 between screw 5 and the screw groove upside on the drill body 1 below external diameter, spanner inserts spanner locating hole 6, drive overcoat 3 and rotate, drive screw 5 and rotate, drive jaw 2 and unclamp or clamp drilling cutters, because the effect of thrust bearing 4, screw 5 does not rub with screw groove upper side plane, and rotating torque is little, clamps or to unclamp drilling cutters input torsion little, output torque is big, rotates light.
