Since 7 shape of workpiece to be processed is peculiar, product shape is completely random, unique regular domain will also because of processing and It is not available, it is difficult to result in production clamping.Therefore, the self-positioning special fixture of the utility model machining center utilizes work to be processed The axis hole 8 of part 7, and consider that following key point is designed:
1, product outer shape is complicated, random face, no anchor point, difficult clamping;
2, product hardness is very high, and in cutting process, cutting force is big;
3, workpiece size is stringent, it is necessary to guarantee to deform in clamping engineering.
Utility model content
The utility model mainly solves that workpiece to be processed shape is random, leads to the technical problem for producing clamping difficulty, mentions The self-positioning special fixture of a kind of machining center out, to overcome workpiece to be processed complex contour, clamping difficult, clamping that can be stable Workpiece to be processed.
The utility model provides a kind of self-positioning special fixture of machining center, comprising: tooling main body (6), positioning pin (1), hold-down bolt (2), pressing plate (3) and compression guide holder (4);
The pressing plate (3) is connected on tooling main body (6) by compressing guide holder (4), and pressing plate (3) passes through hold-down bolt (2) it is fixed on tooling main body (6);
Pin hole, the center of circle of the pin hole of the pressing plate (3) and the central coaxial of tooling main body (6) is arranged in the pressing plate (3);
The positioning pin (1) is used to sequentially pass through the axis hole (8) of the pin hole of pressing plate (3), workpiece to be processed (7), is against work Behind main body (6) center of dress, positioned.
Further, the tooling main body (6) is fixed on the table by fixing bolt (5).
Further, the quantity of the fixing bolt (5) is 4, and 4 fixing bolts (5) are evenly distributed on tooling main body (6) circumferential direction.
Further, the tooling main body (6) is cylinder.
The self-positioning special fixture of a kind of machining center provided by the utility model, clamping complex contour that can be stable to Workpieces processing improves production efficiency, saves production cost.Simple, easy for installation, stabilization can with manufacture craft for the utility model Lean on, long service life the advantages that.
