Description
Technical field
The utility model relates to a kind of toolings for annular workpieces.
Background technique
There are many disk-like accessories on circular disc knitting machine, thickness is little, and substantially within 150 millimeters, diameter compares
Greatly, there are about one meter four or so, and there are bigger hole, about 800 or so in centre.Have many holes on part, have stepped hole,
Threaded hole etc..If these parts are processed on numerical control drilling machine, although process velocity is fast, the clamping and centering of workpiece are wanted
A big chunk time is expended, processing efficiency can not improve.This requires it is a set of can with the frock clamp of self-centering clamping,
To improve the speed of clamping centering.
Summary of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, to provide and a kind of determine for large-diameter circular annular workpiece
Heart tooling, it can be achieved that annular workpiece self-centering.
The purpose of this utility model is realized by following technical solution：
A kind of centering tooling for annular workpiece, it is characterised in that：Including pedestal, it is rotatably provided on pedestal
Turntable, the multiple sliding blocks that can be set on the base with being moved radially along turntable, the claw being arranged on sliding block, driving turntable rotation
Driving mechanism, be formed with helicla flute on turntable, the driving column being provided on sliding block in insertion helicla flute, spiral when turntable rotates
Slot and driving column cooperation driving sliding block moving radially along turntable.
Further, multiple driving columns along the turntable arranged radially are provided on the sliding block.
Further, the driving mechanism includes the first gear being co-axially located on the turntable, is operated rotatably
Operating stick and be arranged in operating stick second gear engaged with the first gear.
Further, the pedestal is provided with the pivotal axis of protrusion, and the center of the turntable and first gear is each formed with
For the axis hole that pivotal axis passes through, it is provided with gland at the top of pivotal axis, the operating stick is rotatably provided on gland.
Further, the claw has support construction, which includes being used to support the horizontal support surface of workpiece
The vertical supporting surface of top tight workpiece is used for connection horizontal support surface.
Further, the claw has multiple support constructions along the turntable arranged radially.
The utility model has the advantages that：
Helicla flute and driving column cooperation driving sliding block moving radially along turntable, realize the movement of sliding block simultaneously when turntable rotates
Claw is driven to withstand the inner hole hole wall or release annular workpiece of annular workpiece；It is provided on sliding block along turntable arranged radially
Multiple driving columns, it is ensured that the mobile accuracy of sliding block keeps it in moving radially for turntable, with guarantee annular workpiece with
The concentricity of turntable axis；Multiple support constructions are arranged to be adapted to not have to the annular workpiece of size.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of turntable.
Specific embodiment
Referring to Figures 1 and 2 shown in, a kind of centering tooling for annular workpiece, including pedestal 1, turntable 2, sliding block 6,

Pedestal 1 is provided with pivotal axis 12 vertically raised and radially extends three sliding slots of simultaneously circle distribution along pivotal axis 12
11, three 6 activities of sliding block are disposed in sliding slot 11, and three claws 3 are fixed on corresponding sliding block 6, during turntable 2 is formed with
Heart hole 22, turntable 2 are rotatably set on pivotal axis 12 by centre bore 22, and 2 bottom surface of turntable is formed with helicla flute 21；
Multiple driving columns 61 along 2 arranged radially of turntable are provided on sliding block 6, driving column 61 is protruded into helicla flute 21, driven
Motivation structure includes the first gear 53 being co-axially located on turntable 2, is operated rotatable operating stick 51 and be arranged in operating stick
The second gear 52 engaged on 51 with first gear 53, first gear 53 are centrally formed with the axis hole passed through for pivotal axis 12,
Gland 4 is provided at the top of pivotal axis 12, operating stick 51 is rotatably provided on gland 4 by bearing block.
51 upper end of operating stick is provided with the polygonized structure with spanner cooperation, can make 51 turns of operating stick by spanner operation
Dynamic, the rotation of operating stick 51 can drive second gear 52 to rotate, and second gear 52 drives first gear 53 to rotate, and finally drive turntable
2 rotations, helicla flute 21 and driving cooperation driving sliding block the moving radially along turntable of column 61 when turntable 2 rotates.
Claw 3 has multiple support constructions along 2 arranged radially of turntable, which includes the water for being used to support workpiece
Flat supporting surface 31 and connection horizontal support surface 31 are used for the vertical supporting surface 32 of top tight workpiece centre bore hole wall.
When specific operation, annular workpiece is placed in the horizontal support surface 31 of claw 3, is then operated and is grasped by spanner
Make the rotation of bar 51, rotates turntable 2, helicla flute 21 and driving cooperation driving the moving radially along turntable 2 of sliding block 6 of column 61, finally
Three claws 3 are synchronized to be moved radially outwards, the vertical supporting surface 32 of claw 3 holds out against the hole wall of annular workpiece centre bore,
Realize the centering installation of annular workpiece.
The above, the only preferred embodiment of the utility model, therefore the utility model implementation cannot be limited with this
Range should still belong to this that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description
In the range of utility model patent is covered.
