Description
Technical field
Invention, which is related to, to keep being installed on the main shaft of work mechanism and with spiral shell in the rotation progress of main shaft in the state of screw tap
The tap chuck of line processing, more particularly to a kind of flexible tap chuck structural assembly.
Background technology
Existing tap chuck is divided into fixed clamp and the major class of flexible clamping two, they the advantages of be fixed screw tap respectively
Chuck structure is simple, small volume, and chucking power is strong, and screw tap bounce is small after clamping, suitable for the tapping of all directions；Flexible screw tap clamp
Head can be adjusted by gap makes screw tap self-centering, protects screw tap and screw thread without damage by adjusting stopping power size；
They the shortcomings that are that fixed tap chuck can not be adjusted to tapping power, tapping center can not be adjusted, easily respectively
Cause screw tap or thread damage；Flexible tap chuck is complicated, and volume is big, and chucking power is relatively small, due to be it is flexible, only
Suitable for there is the vertical direction tapping of larger space.
Therefore, it is necessary to a kind of new tap chuck, while there is the advantages of fixed and flexible tap chuck, structure
Simply, small volume, chucking power is strong, and screw tap bounce is small after clamping, there is certain regulation to screw tap, being capable of fast and effectively positioning filament
Cone, effectively improves life of tap and tapping effect, the non-vertical direction tapping small especially suitable for space.
The content of the invention
The purpose of invention is to provide a kind of flexible tap chuck structural assembly, and simple in construction, small volume, chucking power is strong,
Screw tap bounce is small after clamping, there is certain regulation to screw tap, can fast and effectively positioning screw tap, effectively improve life of tap and
Tapping effect, the non-vertical direction tapping small especially suitable for space.
The flexible tap chuck structural assembly of invention, including main handle and with tubular cramping body chuck and match somebody with somebody with chuck
The screw tap of conjunction, is provided with the retainer for screw tap on the chuck, and the retainer can be along the radial and axial shifting of cramping body
It is dynamic；
Further, be provided with the chuck can axial deformation elastomeric element；
Further, what the retainer included to move axially along cramping body stirs overcoat and is set simultaneously through clamping body wall
The ball that can be moved radially along cramping body, the groove with ball engagement is provided with the screw tap bare terminal end；
Further, along it is described clamping body wall circumference spaced set have it is multiple run through through hole, the ball is arranged at through hole
It is interior；
Further, the overcoat of stirring is by that can accommodate the space of ball and be formed with the lug boss of ball interference fit；
Further, the spring for stirring overcoat axial movement is provided with the chuck；
Further, the overcoat section of stirring is T-shaped structure, is provided with the chuck for entering to ball receiving space
The spacing catch of row；
Further, the jump ring for stirring overcoat is provided with the chuck；
Further, the elastomeric element is spring, and the spring is fixed in tubular cramping body cecum.
The beneficial effect of invention：The flexible tap chuck structural assembly of invention, simple in construction, small volume, chucking power is strong, folder
It is small to hold the bounce of rear screw tap, there is certain regulation to screw tap, can fast and effectively positioning screw tap, effectively improve life of tap and attack
Silk effect, the non-vertical direction tapping small especially suitable for space.
Brief description of the drawings
Invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the cross-sectional view of invention；
The stereogram of Fig. 2 inventions.
Embodiment
Fig. 1 is the structural representation of invention, the stereogram that Fig. 2 is invented, as shown in the figure：The flexible tap chuck structure of invention
Assembly, including main handle 1 and the chuck 2 with tubular cramping body and the screw tap 5 with the cooperation of chuck 2, are set on the chuck 2
There is the retainer for screw tap 5, the retainer can move along cramping body is radial and axial.Retainer, which moves radially, to be used for silk
Cone 5 out of cramping body extract or for the fixation after clamping, retainer move axially for make screw tap 5 when contact workpiece and
Advancing main shaft has certain distance of stretch out and draw back.
In the present embodiment, be provided with the chuck 2 can axial deformation elastomeric element 11；Elastomeric element may also be arranged on
The clamping end of screw tap 5, solves the problems, such as excessive contact.
In the present embodiment, what the retainer included to move axially along cramping body stirs overcoat 3 and through clamping body wall
Set and the groove with the cooperation of ball 4 can be provided with the bare terminal end of screw tap 5 along the ball 4 that cramping body moves radially；Work as dress
During folder, stir overcoat 3 and axially ball 4 is slipped into the groove of screw tap 5 to a side movement screw tap 5 is fixed, chuck is entered
When row is changed, stirring the movement of 3 axial opposite direction of overcoat makes ball 4 skid off the groove 6 on screw tap 5, unties screw tap 5 and fixes, reaches
The purpose of replacing.
In the present embodiment, along it is described clamping body wall circumference spaced set have it is multiple run through through hole 7, the ball 4 is set
In in through hole 7；Ball 4 realizes and moved radially that the fixation of ball is fixed by way of prior art along through hole 7.
In the present embodiment, the overcoat 3 of stirring is by the lug boss that can accommodate the space of ball 4 and be interference fitted with ball 4
Form；Groove 6, which has, is adapted to the arc-shaped inner surface on the surface of ball 4, after ball 4 is slipped into the groove 6 of screw tap 5, lug boss with
The intimate surface contact of ball 4 reaches the fixed screw tap 5 of interference fit, and when changing, lug boss departs from ball 4, and screw tap 5 is to cramping body
Outer movement, drive ball 4 be moved to along through hole 7 stir overcoat 3 accommodate the space of ball 4, release screw tap 5 and fix and realize and change
Purpose.
In the present embodiment, the spring 8 for stirring the axial movement of overcoat 3 is provided with the chuck 2；It is simple in construction, together
When be easy to make screw tap 5 to have certain distance of stretch out and draw back with advancing main shaft when contacting workpiece.
In the present embodiment, the section of overcoat 3 of stirring is T-shaped structure, is provided with the chuck 2 for holding to ball 4
Receiving space carries out spacing catch 9；Catch 9 is used to limit receiving space.
In the present embodiment, the jump ring 10 for stirring overcoat 3 is provided with the chuck 2；Limited for stirring overcoat 3
Position, and then spacing fixation is realized to retainer.
In the present embodiment, the elastomeric element 11 is spring, and the spring is fixed in tubular cramping body cecum, solved
Spend contact problems.
Finally illustrate, above example only to illustrate invention technical scheme and it is unrestricted, although with reference to preferable
Invention is described in detail embodiment, it will be understood by those within the art that, can be to the technical scheme of invention
Modify or equivalent substitution, without departing from the objective and scope of inventive technique scheme, it all should cover the right in invention
Among claimed range.
