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:

It should be noted that, unless otherwise clearly defined and limited, term " first ", " second " etc. do not represent order and install, and do not represent the importance of described element yet.

Refer to Fig. 1-Fig. 3, Fig. 7-Fig. 8, the special fixture of machining large cutter shaft box parts: comprise chuck body 1, for part to be processed and chuck body are fixed moving press plate 15, regulate support pin 16, prevent part to be processed from adding the gripper shoe 20 and securing member trembleed man-hour.Be shaped with the lower datum level 5 coordinated with machining tool bottom described chuck body, be shaped with the upper datum level 2 coordinated with part to be processed at chuck body top, described chuck body one side is shaped with the centering datum level 6 for processing parts centering; Be shaped with groove 4 at chuck body top, in described groove, a side be shaped with the oriention benchmark face 3 for processing parts.

In the present embodiment, upper datum level and the lower datum level of described chuck body are the face of being parallel to each other, its depth of parallelism franchise value is less than 0.008mm, described upper datum level, lower datum level and centering datum level are mutual vertical plane, its perpendicularity franchise value is less than 0.01mm, described centering datum level and oriention benchmark face are mutual vertical plane, and its perpendicularity franchise value is less than at 0.01mm.

In the present embodiment, described chuck body is provided with 4 moving press plates 15,4 for fixed cutting tool case part and regulates support pins 16 and 4 adding gripper shoe 20 and the securing member of play in man-hour for preventing part to be processed, and described securing member is preferably stud 17, outer six square bolts 21 and SOC.HD. cap screw 22.

In the present embodiment, uniform 4 the lifting suspension ring 14 in described chuck body corner place.

Because on this fixture, datum level, lower datum level are the face of being parallel to each other, its parallelism error value is less than 0.008mm, be mutual vertical plane with centering basal plane 6, its error of perpendicularity is less than at 0.01mm, oriention benchmark face 3 and centering datum level 6 are mutual vertical plane simultaneously, and with upper datum level, lower datum level is also mutual vertical plane, its perpendicularity franchise value is all less than 0.01mm, this ensures that there datum level 2 on fixture, lower datum level 5, the upper surface 7 of oriention benchmark face 3 and cutter box parts, lower surface 8, convex key left surface 9 and the uniformity with stock-removing machine workbench 200, overall accumulated error is dropped to minimum, thus make the cutter shaft box parts processed meet designing requirement, ensure that the machining accuracy of cutter shaft box parts.

Operation principle of the present utility model is:

Refer to Fig. 7 and Fig. 8, first datum level under chuck body 5 is placed on machining tool workbench 200, by cutter shaft box parts 100 according to being placed in chuck body 1 shown in Fig. 7 and Fig. 8, the left surface 9 of the convex key 10 of cutter shaft box parts must be close to chuck body oriention benchmark face 3, must not have space.Then tightened together with chuck body 1 by moving press plate 15, adjustment support pin 16, stud 17, nut 18, packing ring 19.In order to prevent cutter shaft box parts from trembleing man-hour adding, three sides of chuck body are installed gripper shoe 20, outer six square bolts 21 and SOC.HD. cap screw 22, to ensure that cutter shaft box parts is adding the stability in man-hour.

Because this clamp precision is high, reasonable in design, and the error of each relative dimensions also drops to minimum, so just ensure that the convex key left surface 9 of cutter shaft box parts and upper surface 7, the error of perpendicularity between lower surface 8 is less than 0.01mm, inclined-plane 12 and the upper surface 7 of T-shaped keyway 13, the error of perpendicularity between lower surface 8 is less than 0.01mm, the error of perpendicularity between the inclined-plane 12 of T-shaped keyway and convex key left surface 9 is less than 0.01mm, dead eye 11 center line and upper datum level, between lower datum level, parallelism error is also less than 0.01mm, thus make the cutter shaft box parts everyway processed meet designing requirement, ensure the machining accuracy of cutter shaft box parts, quality and reliability.

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.
