The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As Fig. 1, the utility model device is a kind of calibration template that is used for the machining large axial workpiece, and its structure is to comprise calibration template 1, jackscrew 2, contour v block 4.Calibration template 1 is provided with three adjustable jackscrews 2, is used for the tightening between calibration template 1 and the shaft parts 3.

Fig. 1 is the structural representation of the utility model embodiment, the mounting means that has shown part, the shaft parts 3 of needs processing is lain in a horizontal plane on two contour v blocks 4, load onto calibration template 1 at the canned paragraph of shaft parts 3 then, after axially drawing the table centering with dial gauge, with jackscrew 2 the calibration template 1 and the canned paragraph of shaft parts 3 are fixed along circumference, fastened (pressing plate does not show in the drawings) with pressing plate.

Fig. 2 be A among Fig. 1 to view, the calibration external surface of calibration template 1 is that the angle fine finishining according to part to be processed inclined-plane, keyway forms, and can make the external surface of different angles, as planar I 7 and plane II 8.The cylindrical of the axle center hole of calibration template 1 and shaft parts to be processed 3 is a fit dimension, and three keyways of processing keyway 5 for needing on shaft parts 3 processing sections to process, processing inclined-plane 6 are 25 ° inclined-plane for two β angles that need on shaft parts 3 processing sections to process.

Fig. 3 is the A-A cutaway view of shaft parts 3 embodiment among Fig. 1, needs to process three on the shaft parts 3 that needs to process

The angle is the processing inclined-plane 6 that 120 ° five equilibrium processing keyway 5 and two β angles are 25 °.

Fig. 4 is the front view of calibration template, and the planar I 7 in the calibration external surface of calibration template 1, planar I I 8 are the angles according to part to be processed

, β is finish-machined to.The planar I 7 of processing centering keyway is parallel with the keyway bottom surface on the calibration template, is used for centering processing keyway 5, and the planar I I 8 on processing centering inclined-plane and β meet at right angles and be used for centering and process inclined-plane 6 on the calibration template.

Fig. 5 is the side view of Fig. 4.The termination of jackscrew 2 is lower than each planar I 7 or the planar I I 8 on the calibration template.

With reference to Fig. 1, Fig. 4, the operation principle of the utility model device is,

At first, according to the angle of part to be processed inclined-plane, keyway β is at calibration template 1 outer surface fine finishining out-of-plane I 7 or planar I I 8;

Secondly, the shaft parts 3 of needs processing is lain in a horizontal plane on two contour v blocks 4, load onto calibration template 1 at the canned paragraph of shaft parts 3 then, after axially drawing the table centering with dial gauge, with jackscrew 2 the calibration template 1 and the canned paragraph of shaft parts 3 are fixed along circumference, fasten with pressing plate, begin to process first processing keyway 5;

Three, first processing is unclamped pressing plate after keyway 5 machines, and rotational parts axle 3 draws table water detection flat next planar I I 8 of calibration template 1, fastens shaft parts 3 once more, the next inclined-plane 6 of beginning processing parts axle 3;

Repeat above step and can finish all calibration processing.

The utility model device simple in structure, cost is low, and is easy to operate, and the angle that can process is as required made different calibration external surfaces, has reduced manufacturing cost, has guaranteed crudy.
