Description
Technical field
The utility model belongs to chuck apparatus technical field, is related to a kind of bore mill magic chuck.
Background technology
To ensure gear-driven stationarity and accuracy, currently the majority enterprise is all positioned by pitch circle retainer, folder
Tightly, and autogenous grinding claw, it is ensured that the bore and pitch circle after processing are concentric.The deficiency of this mode is in be changed in each
During gear kind claw all must autogenous grinding, adjustment time is longer and requires higher to the operative skill of operative employee.
The content of the invention
For the utility model in view of the above-mentioned problems, providing a kind of bore mill magic chuck, it is effectively suitable that the block changes fixture
Processing for small batch gear, it is possible to achieve high-quality and efficient production.
According to the technical solution of the utility model：A kind of bore mill magic chuck, including housing and slip are set
Jacking block in the pilot hole of housing, flexible sheet and claw are installed on housing, it is characterised in that：The face installation of trying to get to the heart of a matter of housing is solid
Fixed column, fixed column are stretched out from the through hole of flexible sheet, and pedestal is fixed in fixed column, and end face location-plate location and installation is in pedestal
On outer face, retainer is installed on the end face location-plate, retainer includes three sections of arc shapes divided equally and keeps frame plate, every section of guarantor
The inwall for holding frame plate is provided with locking ball by flexible steel wire, and the external diameter of three sections of holding frame plates is consistent, the outer ring of retainer
Claw is set, and claw is fixedly connected with flexible sheet, and claw inner ring is connected with the outer ring of retainer.
As further improvement of the utility model, flexible steel wire is crossed in the hole of the centre of sphere from locking ball and passed, flexible
The both ends of steel wire are both secured on retainer.
As further improvement of the utility model, claw installing plate, claw installation are installed in the flexible sheet outer surface
In on claw installing plate.
As further improvement of the utility model, the jacking block, flexible sheet, pedestal and end face location-plate are provided with and passed through
Lead to the hole connect.
It is of the present utility model to have technical effect that：The utility model product determines a round principle according to 3 points, will save
Round retainer makes three-chip type, plays positioning and clamps use, locking ball steel wire flexibility invests inner surface, and steel ball and inner surface are straight
Footpath is changed by the parameter of gear, and in the range of certain pitch diameter, retainer external diameter is made unanimously, is so changing every time
It need not just be adjusted during kind and change the production time with autogenous grinding claw, shortening, reduce the requirement to the operative skill of operative employee.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model product retainer gripper.
Embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1,2, including retainer 1, locking ball 2, claw 3, end face location-plate 4, pedestal 5, screw 6, flexible sheet
7th, housing 8, claw installing plate 9, jacking block 10, fixed column 11, gear 12 etc..
As shown in Figure 1, 2, the utility model is a kind of bore mill magic chuck, including housing 8 and sliding is set
Jacking block 10 in the pilot hole of housing 8, flexible sheet 7 and claw 3, the face installation fixed column of trying to get to the heart of a matter of housing 8 are installed on housing 8
11, fixed column 11 is stretched out from the through hole of flexible sheet 7, and pedestal 5 is fixed in fixed column 11, the location and installation of end face location-plate 4
In on the outer face of pedestal 5, installing retainer 1 on the end face location-plate 4, retainer 1 includes three sections of arc shapes divided equally and kept
Frame plate 1-1, every section keeps frame plate 1-1 inwall that flexible steel wire is provided with locking ball 2, and three sections keep frame plate 1-1's
External diameter is consistent, and the outer ring of retainer 1 sets claw 3, and claw 3 is fixedly connected with flexible sheet 7, the inner ring of claw 3 and retainer 1
Outer ring is connected.
Flexible steel wire is crossed in the hole of the centre of sphere from locking ball 2 and passed, and the both ends of flexible steel wire are both secured to retainer 1
On.
The outer surface of flexible sheet 7 installation claw installing plate 9, claw 3 is installed on claw installing plate 9.
Jacking block 10, flexible sheet 7, pedestal 5 and end face location-plate 4 are provided with the hole of through connection.
The course of work of the present utility model is as follows：Outside rotary motive power oil cylinder provides power by jacking block 10 by flexible sheet
7 turn right top, its is produced elastic deformation, drive the spreading of claw 3, now load workpiece, locking ball 2 is caught in the tooth of gear 12
Groove, the end face of gear 12 are bonded with end face location-plate 4, button press, and oil cylinder commutation, jacking block 10 leaves flexible sheet 7, flexible sheet
7 elastic recoverys, and clamped gear 12 by retainer 1 and locking ball 2, such workpiece just installs.Due to retainer 1
Outside dimension is consistent, thus need not every time more 12 kind of gear changing when to fixture carry out autogenous grinding, greatly shorten change production the time.
