Description
Technical field
This utility model belongs to mechanical equipment technical field, has novel locking mechanism particularly to a kind of
Drill chuck.
Background technology
Three jaws, sets in the jaw hole that in prior art, drill chuck includes drill body, be arranged on drill body
Drill body rear portion and jaw threaded engagement nut, be enclosed within nut outside and drive nut rotation sleeve,
And bonnet, three jaws are separately positioned in three inclined holes being distributed on drill body, between nut and jaw
Using threaded, during work, by turnbarrel, and then drive nut, then nut drives jaw
Move forward and backward in the inclined hole of drill body, so that jaw opens or closes, to realize unclamping or clamping tool.
Sleeve passes through spring bracing and nut screw connection, can relatively rotate, but work as jaw between sleeve and nut
During clamping drill bit, the clamping force between sleeve and drill body is unstable, and locking is not sufficiently stable reliable, this practicality
Novel therefore.
Summary of the invention
This utility model purpose is to provide a kind of drill chuck with novel locking mechanism, its simple in construction,
Clamping force between sleeve and drill body is stable, it is ensured that the work efficiency of drill chuck.
Based on the problems referred to above, the technical scheme that this utility model provides is:
A kind of drill chuck with novel locking mechanism, including drill body, be arranged on drill body jaw hole in
Three jaws, it is enclosed within the nut of described drill body rear portion and described jaw threaded engagement, is enclosed within outside described nut
Portion also drives sleeve and the bonnet of described nut rotation, described sleeve include outer sleeve and with described overcoat
The sleeve embedded component that cylinder coordinates, described drill body rear portion is provided with boss position described nut, described nut and
Being provided with bearing and pad between described boss, the outer wall in the middle part of described drill body is provided with unidirectional ratchet, described
Be provided with locking mechanism between sleeve embedded component and described drill body, described locking mechanism include spring bracing and
Spring leaf, described spring leaf forms multiple first locking foot and one second locking foot, described first locking
Foot and described second locking foot protrude from outside described spring leaf, and described second locking foot is in described spring leaf
Extending and form sticking department, described first locking foot and described second locking foot stretch out described spring bracing
Dodging hole to coordinate with described sleeve embedded component, the inwall of described sleeve embedded component is provided with and described first lock
The first limiting section that tight foot coordinates and the second limiting section and the sticking department coordinated with described second locking foot and
Release portion, described spring bracing is provided with multiple rotation card base, and described sleeve embedded component inwall is provided with
The draw-in groove coordinated with described rotation card base, when described jaw attempt clamp drill bit time, described rotation card base with
Having gap between draw-in groove, described first locking foot is positioned at described first limiting section, described second locking foot
Being positioned at described release portion, now rotational sleeve drives described first locking foot, the second locking foot thus drives
Described spring bracing rotates, and described spring bracing drives described nut rotation, when jaw will clamp
During drill bit, being rotated further sleeve, described sleeve embedded component rotates relative to described spring leaf, described first lock
Tight foot is spacing in described second limiting section, and the most described second locking foot is moved by described release portion
To described sticking department, described second locking foot is compressed to be moved to described drill body, and described sticking department is resisted against
By described nut locking on the ratchet of described drill body outer wall, between described rotation card base and draw-in groove, gap is disappeared
Removing, sleeve directly drives described spring bracing to rotate, and spring bracing drives spring leaf to be rotated further,
The when of unclamping, tight lock part is resisted against on unidirectional ratchet, and spring leaf can not rotate backward, and sleeve is relative to spring
Sheet rotates backward, and the second locking foot discharges in release portion, and sticking department departs from unidirectional ratchet, and then unclamps
Whole chuck.
In some embodiments wherein, described spring bracing includes base portion and spring supporting portion, institute
State base portion to be set on described nut and be fastenedly connected with described nut, described spring supporting portion in the form of a ring and
Outer wall dodges hole described in being provided with, and described rotation card base is arranged on described spring supporting portion.
In some embodiments wherein, described spring supporting portion is provided with three and rotates card base.
In some embodiments wherein, described spring leaf forms two first locking feet.
Compared with prior art, the utility model has the advantages that:
Use the technical solution of the utility model, the locking machine arranged between sleeve embedded component and drill body
Structure, when jaw will clamp drill bit, sleeve embedded component moves relative to spring leaf, and the first locking foot is the
Two limiting sections are spacing, and meanwhile the second locking foot is moved to sticking department by the portion of release, the second locking foot quilt
Compression is moved to drill body, and sticking department is resisted against nut locking on the ratchet of drill body outer wall；Locking time
Wait, owing to arranging multiple first locking foot so that coupling mechanism force is more prone to regulation, can increase coupling mechanism force,
So there is between sleeve and drill body stable clamping force so that drill bit stablized to be clamped in jaw it
Between, it is to avoid drill bit gets loose, it is ensured that the work efficiency of drill chuck.
