Abstract
A self-centering outer-diameter clamp is composed of a clamp base and a clamp pull rod. The clamp base is composed of a contracting face, a guiding face and a mounting face. The clamp pull rod is composed of a spindle connecting thread, a connecting rod, a guiding step, a contracting receding groove and a contracting body. The self-centering outer-diameter clamp is characterized in that the clamp pull rod is inserted into the clamp base, and the clamp is positioned through the guiding step and the guiding face. The self-centering outer-diameter clamp is simple and reliable in structure, a workpiece is convenient to assemble and disassemble, self-centering can be achieved, machining precision is improved, and the concentricity and perpendicularity of a machined face and a workpiece inner hole can be guaranteed; and the self-centering outer-diameter clamp is suitable for being applied and popularized in the fields where positioning and clamping need to be achieved relying on workpiece inner holes.
Description
Technical field
The present invention relates to field of machining, more particularly to a kind of self-centering external diameter fixture of part processing.
Background technology
In order to process the surface for meeting regulation technical requirements, the positioning of workpiece must will be realized on the lathe of clamping workpiece and is clamped before processing, when workpiece is installed, usually first position and clamp afterwards, and when workpiece being installed on scroll chuck, positioning is carried out simultaneously with clamping, workpiece is directly installed on platen or universal fixturing, some workpiece are positioned by its endoporus and are clamped, or and existing fixture structure is more complicated, be exactly unload it is cumbersome, and self-centering can not be realized mostly, tend not to enough meet condition requirement, cause machining accuracy poor.
The content of the invention
It is an object of the invention to provide a kind of self-centering external diameter fixture, internal diameter and external diameter processing of the fixture suitable for cylindrical part.
The technical scheme is that what is be accomplished by：A kind of self-centering external diameter fixture, it is made up of clamp base, clamp pull rod, described clamp base is made up of contraction front, guiding face, mounting surface, and described clamp pull rod is made up of main shaft connection screw thread, connecting rod, guiding step, contraction escape groove, liquid shrinkable, it is characterised in that：Inside described clamp pull rod insertion clamp base, fixture is positioned with guide surface by guiding guide table rank.
Described liquid shrinkable portion centers are provided with centre bore, are uniformly arranged the notch of six deep equalities to vertebral body outer with one heart along centre bore, and liquid shrinkable is divided into six parts.
Described contraction front be a female cone dignity, liquid shrinkable be a cylindrical cone structure, female cone dignity angle it is less than cylindrical cone angle.
Beneficial effects of the present invention：Simple structure, workpiece it is easy to loading and unloading, and self-centering can be realized, improve machining accuracy, structure reliability ensure that concentricity, the perpendicularity of machined surface and inner hole of workpiece, be adapted to by inner hole of workpiece promote the use of in the field with clamping to realize positioning.
Description of the drawings
Fig. 1 be the present invention cut open schematic diagram.
Specific embodiment
Known by Fig. 1，A kind of self-centering external diameter fixture，By clamp base 1、Clamp pull rod 2、Contraction front 3、Guiding face 4、Mounting surface 5、Main shaft connection screw thread 6 is constituted，Inside the described insertion clamp base 1 of clamp pull rod 2，Fixture is positioned with guide surface 4 by guiding guide table rank，Described contraction front 3 is a female cone dignity，Liquid shrinkable is a cylindrical cone structure，Female cone dignity angle is less than cylindrical cone angle，Described liquid shrinkable is connected with guiding step，Coupling part is provided with contraction escape groove，Described liquid shrinkable portion centers are provided with centre bore，The notch of six deep equalities is uniformly arranged to vertebral body outer with one heart along centre bore，Liquid shrinkable is divided into six parts，When fixture is made，After first install fixture，Clamp using little pressure is empty，It is then finished to centre bore，So ensure that workpiece in the case of indeformable can well be fixed and be processed，During processing part，First clamp base 1 is fixed on lathe，Again main shaft connection screw thread is connected with main shaft，Again part is placed between contraction front 4 and liquid shrinkable，Start lathe，Shrink escape groove itself to deform upon in clamp pull rod 2 to the left motor process，Simultaneously because squeezing action of the female cone dignity to liquid shrinkable，Six parts of liquid shrinkable diminish to central reduction simultaneously，Reach the purpose of Clamp blocks external diameter.
