Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to 1-Fig. 4, the special fixture of machining large tilt body part, comprise chuck body 1, clamping press plate, adjustment support pin, special stand and special washer, the end face of described chuck body be provided with for prevent part to be processed add play in man-hour clamping press plate 16, stud 13, nut 14, packing ring 15, regulate support pin 17, special stand 11, special washer 12 and sphere end holding screw 10.Described chuck body right side is the right datum level 6 matched with platen 200, described chuck body end face is the upper datum level 2 matched with placement part to be processed 100, and this datum level is an inclined-plane, described chuck body bottom surface is lower datum level 7, at chuck body top, middle position place is provided with datum hole A4, is shaped with datum hole B8 bottom chuck body.
In the present embodiment, in described chuck body, uniform three add the clamping press plate 16 of play in man-hour and the special stand 11 of location for preventing part to be processed.
In the present embodiment, left datum level 9 and the upper datum level 2 of described chuck body are mutual vertical plane, described left datum level 9 and right datum level 6 are the face of being parallel to each other, and described lower datum level 7 and right datum level 6 are mutual vertical plane, and the error amount of its error of perpendicularity value and the depth of parallelism is all less than 0.01mm.
In the present embodiment, described datum hole A4 center line is mutually vertical with upper datum level 2, and its error of perpendicularity value is less than 0.008mm; Described datum hole B8 center line and right datum level 6 are parallel to each other, and the error amount of its depth of parallelism is less than 0.008mm; And centering cylindrical 23 center line of the center line intersection point I 3 of the center line of datum hole A4 and datum hole B8 and part to be processed 100 and centre bore 19 center line intersection point II 21 match; Described datum hole A4 and part to be processed centering excircle dimension match, its fit clearance error amount is less than 0.005mm, and the gradient of upper datum level 2 is consistent with part to be processed centering end face 22 gradient, this guarantees the uniformity of fixture and part to be processed, ensure that precision and the quality of part to be processed.
Operation principle of the present utility model is:
Refer to Fig. 5-Fig. 7, as shown in Figure 6, first the right datum level 6 of chuck body 1 is placed on machining tool workbench 200, then by the centering cylindrical 106 of part to be processed 100, centering end face 105 is placed on the datum hole A4 of chuck body respectively, on datum hole A end face 5 position, and ensure steadily, by clamping press plate 16, regulate support pin 17, stud 13, nut 14, packing ring 15 and special stand 11, special washer 12, part to be processed 100 and chuck body 1 are fixed together by sphere end holding screw 10, the datum hole B8 of centering fixture and lower datum level 7 are within 0.008mm, the upper surface 101 of processing parts, centre bore 102 and centre bore inner end 103 to final size.Because the intersection point I 3 of fixture and intersection point II 104 size of part to be processed match, the upper datum level 2 of chuck body is consistent with centering end face 105 gradient of part to be processed, centering cylindrical 106 size of datum hole A4 and part to be processed matches, and its dimensional fits gap error value is less than 0.005mm, this ensures that there the uniformity of fixture and part to be processed, thus it is minimum to make accumulated error value drop to, the large-scale tilt body part processed is made more to meet drawing requirement.
The embodiment that the utility model accompanying drawing describes is exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
