Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 3, the special fixture of machining large work stage body part, comprises the chuck body 1 that forms by base 1-1 with its all-in-one-piece positioning correcting piece 1-2 processed, for by clamping plate 10 fixing to work stage body part end face and chuck body, securing member with for the pressing plate 14 with the longitudinal compression of chuck body by work stage body part.The positioning correcting piece both sides of described chuck body are provided with clamping plate 10, fastening with work stage body part 100 by securing member between two clamping plates, described pressing plate 14 be arranged on positioning correcting piece directly over, be shaped with centre bore 3 in the upper end of described positioning correcting piece.The left side of described positioning correcting piece is shaped with the left datum level 2 coordinating with the stage body part of working, and the right side of described positioning correcting piece is shaped with the right datum level 4 coordinating with the stage body part of working; Be shaped with the upper datum level 6 coordinating with the stage body part of working in the base upper end of described chuck body, base bottom is shaped with the lower datum level 7 coordinating with machining tool.
In the present embodiment, described securing member is preferably stud 11.
In the present embodiment, the upper datum level 6 of described base upper end is the face of being parallel to each other with the lower datum level 7 of base bottom, and with left datum level 2 and the right datum level 4 of positioning correcting piece be mutual vertical plane, its depth of parallelism franchise value and perpendicularity franchise value are all less than 0.008mm.
In the present embodiment, described clamping plate 10 is the round clamping plate coordinating with work stage body hole in piece part.
In the present embodiment, described pressing plate 14 is round clamp.
In the present embodiment, in described chuck body, be also provided with the position line 5 of using for the stage body part lateral extent of working.
Because upper datum level 6 and the lower datum level 7 of chuck body are the face of being parallel to each other, and depth of parallelism franchise value is controlled in 0.008mm, its flatness franchise value is controlled in 0.01mm, and left datum level 2 and right datum level 4 are equally also the faces of being parallel to each other, and its depth of parallelism franchise value is also controlled in 0.008mm, left datum level, right datum level and upper datum level, lower datum level is mutual vertical plane, its perpendicularity franchise value is controlled in 0.008mm, left datum level 2 and right datum level 4 are controlled in 0.01mm for the center line symmetry franchise value of fixture centre bore 3, and between the position line 5 in chuck body and upper datum level 6, be provided with and work stage body hole in piece part center line 18 respectively and between work stage body left side 16 and distance that work matches between stage body right side 15, it is less than 0.01mm apart from dimensional tolerances value, and the centre bore 3 that centering is used while processing in addition, so just ensure the uniformity of chuck body and work stage body part, precision and the quality of work stage body part are ensured.
Operation principle of the present utility model is:
Refer to Fig. 4-Fig. 8, first datum level under chuck body 7 is placed on machining tool workbench 200, then two work stage body parts 100 are placed in chuck body, by clamping plate 10, stud 11, packing ring 8, outer six square nuts 9, work stage body part 100 and this chuck body are fixed together.Because distance between the left datum level 2 of this chuck body and right datum level 4 is fixed, and the distance between this chuck body position line 5 and upper datum level 6 and work stage body hole in piece part center line 18 respectively with work stage body right side 15, between work stage body left side 16, distance matches, again by calculating the cylindrical center, location 21 that just can determine work stage body part location cylindrical 22, then according to the location cylindrical 22 of centre bore 3 centering work stage body parts, after centering completes, in order to prevent that work stage body part work in-process from trembleing, affect precision, recycling round clamp 14, packing ring 12, outer six side's screws 13 will work stage body part compress, can carry out the processing of work stage body part.Because this clamp precision is high, and reasonable in design, and then can ensure the uniformity between work stage body part, chuck body and machining tool three, accumulated error between three is dropped to minimum, thereby make the workbench physical efficiency arrival drawing requirement processing.
The embodiment describing in the utility model accompanying drawing is exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
