Square and torque of uncaging are small, clutch vibration test and the shortcomings that protheca easily loosens when playing test in fact.China Patent No.
201521060623.4 hand fastening drill clutch is increased on the basis of the hand fastening drill clutch of above-mentioned U.S. Patent number US5765839A
Add one or two elastic bumps, be typically provided with the component of elastic bumps, be made of spring steels such as 65Mn, it is necessary to
It can be used through Overheating Treatment rear and there is elasticity, have higher requirement, and elastic bumps are in drill point head clamping to heat treatment
With having certain limitation with discharging process, service life there are one the compressing of elasticity always during release.
Invention content
The object of the present invention is to provide a kind of drill chuck for increasing release torque, to solve drill chuck in high-speed rotating field
Under conjunction, the problem of exiting self-locking state due to emergency stop.For this purpose, the present invention uses following technical scheme：
It is a kind of increase release torque drill chuck, including rotary sleeve, drill body, nut, nut set, clamping jaw, self-locking structure, it is described from
Lock construction includes tooth and spring leaf, and the tooth, which is on drill body or is in, to be fixed on the part on drill body, the spring leaf tool
Have with the matched lock end of tooth, the rotary sleeve have the position that self-locking state is connect with spring leaf and in non-self-locking state and
The position of spring leaf connection and control spring leaf and the cam structure of lock end cooperation, the drill chuck is in rotary sleeve and nut set
Between be additionally provided with self-locking anti-loosing structure；It is characterized in that：The self-locking anti-loosing structure includes inclined-plane and coordinates with the inclined-plane
Auxiliary section, the auxiliary section and the inclined-plane can relatively rotate and clutch on the circumferencial direction of drill chuck, at drill chuck
In self-locking state, the auxiliary section and the inclined-plane are in jam-packed frictional fit state, when the drill chuck exits self-locking shape
When state is to non-self-locking state, the auxiliary section and the inclined-plane are detached from.
Further, the auxiliary section is on rotary sleeve, and the inclined-plane is in nut and puts on.
Further, the auxiliary section and the inclined-plane are in rotary sleeve respectively and nut is put on.
Further, the nut puts on setting driver slot, the rotary sleeve setting and the drive key of driver slot cooperation, institute
The flute length for stating driver slot is more than driving key length, and its difference and drill chuck are Zi non-self-locking state to rotary sleeve during self-locking state
The angle turned over is consistent.
Further, the driver slot is between the Inner arc wall of nut set front end, and the inclined-plane is in the inner circle
On arc wall.
Due to technical solution using the present invention, the present invention by can clutch inclined-plane coordinate it is high to be provided in self-locking state
Retaining frictional force, increase release torque, play locking effect, drill chuck can be prevented under high-speed rotating occasion,
In emergency stop self-locking state is exited due to effect of inertia.And nut set makes without using spring steel and without heat treatment.
Against existing technologies, the present invention is rational in infrastructure, makes simply, locking and anti-loosening property are good.
