Description
Technical field
The present invention relates to Fixture Design technical field, it is related to a kind of Double Oblique Wedge and makes concentric mechanism by oneself.
Background technique
With the progress of science and technology, social development, in order to improve and improve the production efficiency of machining, using certainly
Centering machine is a kind of positioning method very widely used in current Fixture Design field, is applied in such Fixture Design
When adjective-centre structure, usual workpiece cavity is circle, and when workpiece cavity is rectangular, previous adjective-centre structure cannot be guaranteed workpiece two
A direction with centering machine firm contact, can not achieve self-centering simultaneously, need to be changed to more complicated positioning method.So
Machine adds operating personnel to self contering structure, and more stringent requirements are proposed, it is contemplated that existing concentric mechanism of making by oneself can only cope with round type
Chamber, can not achieve square shaped type chamber makes heart function by oneself, is unfavorable for the simplification of tool locating structure.So being directed to rectangular type
The self contering structure design field of chamber is badly in need of a kind of Double Oblique Wedge and makes concentric mechanism by oneself, to solve to perplex this technology always in the prior art
The problem of field personnel.
Summary of the invention
The object of the invention is to solve the above-mentioned problems in the prior art, a kind of Double Oblique Wedge is provided and makes scheming by oneself
Structure, the Double Oblique Wedge make the self-centering positioning that concentric mechanism is applicable not only to rectangular type chamber by oneself, can equally be well applied to circular hole chamber oneself

To achieve the above object, the present invention takes following technical scheme:
A kind of Double Oblique Wedge makes concentric mechanism by oneself, it is characterised in that: including matrix, lower wedge block, upper voussoir, the first claw, the second claw,
Third claw, the 4th claw, shouldered tap bolt, spring and end cap, described matrix one end is equipped with rectangular type chamber and four grooves, described
Upper voussoir front and rear sides are equipped with inclined wedge-shaped T-type groove, and first claw, second claw one end are equipped with inclined wedge-shaped T-type key, upper wedge
Block front and rear sides pass through respectively nested after the T-type key cooperation of T-type groove and the inclined wedge-shaped of the first claw, the second claw is mounted on base
The rectangular type of body is intracavitary；Inclined wedge-shaped T-type groove, the third claw, the 4th claw one end are equipped at left and right sides of the lower wedge block
Equipped with inclined wedge-shaped T-type key, pass through the T-type of T-type groove and the inclined wedge-shaped of third claw, the 4th claw respectively at left and right sides of lower wedge block
The nested rectangular type for being mounted on matrix is intracavitary after key cooperation；First claw, the second claw and third claw, the 4th claw
The groove that the other end passes through matrix respectively stretches out；Described matrix upper end is equipped with end cap, and the end cap central is used for equipped with through-hole
Pass through shouldered tap bolt；Lower wedge block center is equipped with threaded hole, and upper voussoir center is equipped with through-hole, and the shouldered tap bolt sequentially passes through wedge
It is connected after the through-hole of block, spring with the threaded hole of lower wedge block, lower wedge block and upper voussoir is linked together.
It is further preferred that being equipped with open recess at left and right sides of the upper voussoir, lower wedge block is under the action of shouldered tap bolt
It can be nested in the groove of voussoir.
It is further preferred that first claw, the second claw and third claw, the 4th claw use square structure, institute
Stating four grooves that matrix one end is equipped with is square structure.
It is further preferred that first claw, the second claw and third claw, the 4th claw use circular configuration, institute
Stating four grooves that matrix one end is equipped with is circular configuration.
The beneficial effects of the present invention are:
The Double Oblique Wedge makes concentric mechanism by oneself, and operator can be driven by other driving methods such as manual actuation, hydraulic, pneumatic actuation
Shouldered tap bolt, when use, turn shouldered tap bolt clockwise, and lower wedge block moves up, and lower wedge block moves upwardly through inclined wedge-shaped T-type
Inclined-plane squeezes third claw, the 4th claw being in contact with it at key, and two claws are to external extension, when third claw, the 4th claw
Outer end touch positioning workpiece after, the third claw that contact with lower wedge block, the 4th claw stop flexible, and at this moment band shoulder nut is crowded
Voussoir moves down in pressure, and upper voussoir squeezes other first claw, the second claw to overhanging by inclined-plane at inclined wedge-shaped T-type key
Contracting, until the first claw, the second claw are contacted with positioning workpiece.When the first claw, the second claw and third claw, the 4th claw
When with positioning workpiece contact dynamic balance, the centering to workpiece is completed.Shouldered tap bolt need to be only turned when release counterclockwise, in spring
Workpiece is unclamped under spring-force driven dual.
The Double Oblique Wedge makes concentric mechanism by oneself simultaneously, operates conveniently, and cost is cheap, is convenient for marketing.
