Working principle: workpiece to be processed, such as metal blank are placed in above several branch fasteners, so that metal blank
Lower surface contacted with the movable mandril upper surface of branch fastener because the metallic character of metal blank itself, panel surface have
Certain warpage and it is uneven, the movable mandril of each fastener moves down a distance or not under the action of metal blank
It is mobile, after the movable mandril of each fastener is stablized, then can be determined for the metal blank of side placed on it one under it
The consistent supporting surface of surface undulation, at this time pushes up the pushing block of each fastener, and pushing block drives on the quill above it
It moves, the inner conical surface of quill, which moves up, acts on the male cone (strobilus masculinus) that elasticity holds set tightly, and elasticity holds set tightly and is squeezed and shrinks, and holds tightly and lives
Dynamic mandril, the movement of limitation activity mandril, so that the movable mandril of branch fastener is in stationary state, thus to be placed in it
The workpiece of top provides the support stablized and agreed with workpiece lower surface, convenient for the milling equality process operation to plate.
When using above-mentioned high-precision support jig, movable mandril, can be complete with the lower surface of workpiece when supporting workpiece
Full connected simultaneously moves up and down under the action of workpiece, when moving to suitable position, drives quill to move up by pushing block, living
The inner conical surface of moving sleeve, which moves up, acts on the male cone (strobilus masculinus) that elasticity holds set tightly, and elasticity holds set tightly and is squeezed and shrinks, and holds movable top tightly
Fixed support is played the role of in bar, the movement of limitation activity mandril, and the distance that moves down of movable mandril places one's entire reliance upon the work of workpiece
Firmly, i.e., the distance that moves down of movable mandril is continuously adjusted, and the workpiece of different situations is applicable to, when multiple fasteners are applied in combination
When supporting workpiece, it is different according to the difference of workpiece lower surface bending degree that the movable mandril of each fastener moves down distance, because
The support for having curved workpiece to lower surface may be implemented in this, and keeps the natural torsion state of workpiece, clever structure, operation
Simply；
In addition, holding set tightly instead of the steel ball hold-fast body in former scheme using elasticity, structure is simple, and eliminates installation steel ball
Process, substantially increase branch fastener processing efficiency；In addition, passing through the setting of the first wire casing and the second wire casing, and first
Wire casing extends to the second collet without cutting off the second collet, and equally, the second wire casing extends to the first collet without cutting off, and strengthens
It holds the contraction dynamics of set and the stability of structure tightly, so that holding the stability that set holds movable mandril tightly tightly, guarantees mandril to work
Part stablizes support；
In addition, it uses threaded connection, easy to disassemble, i.e., convenient maintenance and cleaning to branch fastener, convenient for intracorporal to shell easy
The replacement of part is lost；In addition, the setting of its interlocking plate, provides interface for the connection of branch fastener and external jig, and use
It is threadedly coupled, easy to disassemble, replacement is versatile to be suitable for the jig of different shape and specification.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
