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 Fig. 1-Fig. 3, the special fixture of the irregular tool-post structure part of machining large, comprise chuck body 1, prevent the moving press plate 16 of tool-post structure part play, regulate support pin 17, for the securing member of tightening tools support body part and special washer 19.Be provided with the lower datum level 4 coordinated with platen bottom described chuck body, be provided with the centering face 5 of centering during processing tool-post structure part on the left of described chuck body, described centering face and lower benchmark are mutual vertical plane; Be provided with on the right side of described chuck body and the right datum level 2 placed tool-post structure part and match, the upper end of described right datum level, higher than the upper surface of chuck body 1, is provided with inclination angle 3 between described right datum level and lower datum level.
In the present embodiment, inclination angle 3 between described right datum level and lower datum level is 110 °, the lower datum level 4 that described chuck body coordinates with platen and and the right datum level 2 placing tool-post structure part between inclination angle 3 match with the angle required by part to be processed, its angle error value is less than 3 '; When the datum level that described chuck body coordinates with platen and left side process tool-post structure part, required centering face is mutual vertical plane, and its error of perpendicularity value is less than 0.008mm.The lower datum level 4 of described chuck body, centering face, left side 5 and right datum level 2, its flatness error value is all less than 0.01mm.
In the present embodiment, described chuck body comprises 2 for preventing the moving press plate of tool-post structure part play, 2 adjustment support pins and 2 securing members and 2 special washer, and described securing member is preferably outer six square bolts 18 and stud 13.
In the present embodiment, above described chuck body, be provided with outer six square bolts and 2 special washer of 2 tightening tools support body parts, be provided with 2 below chuck body and regulate support pin for the moving press plate and 2 preventing tool-post structure part play.
In the present embodiment, described chuck body 1 is in order to be convenient to clamping when processing tool-post structure part, alleviating clamp weight and saving material, reduce costs, and chuck body mid portion adopts and empties structure, makes chuck body convenient in use.
Because the inclination angle 3 between the right datum level 2 of this fixture and lower datum level 4 and the angle 12 between tool-post structure component with inclined plane 8 and centerline hole 9 match, and its error amount controls within 3 ', lower datum level 4 is mutual vertical plane with centering face, left side 5, its error of perpendicularity controls within 0.008mm, lower datum level 4, right datum level 2, left datum level 5 flatness error value all controls within 0.01mm, this guarantees right datum level 2 and the tool-post structure component with inclined plane 8 of fixture, fixture inclination angle 3 and tool-post structure part angle 12, the uniformity of datum level 4 and stock-removing machine workbench 200 under fixture, accumulated error value is made to drop to greatest extent minimum, thus make the tool-post structure part processed meet designing requirement, ensure machining accuracy and quality.
Operation principle of the present utility model is:
Refer to Fig. 3-Fig. 5, first datum level under this fixture 4 is placed on stock-removing machine workbench 200, tool-post structure part 100 is placed in chuck body 1, make the inclined-plane 8 of tool-post structure part together with right datum level 2 close contact of fixture, then tightened together with chuck body 1 by moving press plate 16, adjustment support pin 17, stud 13, outer six square nuts 14, packing ring 15 and outer six square bolts 18, special washer 19, processed by the centering face 5 on the left of centering fixture.Because this clamp precision is high, the accumulated error of each relative dimensions has dropped to minimum all, hole and the end face of its required processing all machine in clamped one time, so just ensure that between part to be processed axis hole A6 and axis hole B7, the scale error value of the spacing of axis hole A6 and axis hole D11 can control within 0.01mm, the intersection point of axis hole C10 center line and axis hole D11 center line can be positioned at the garden that diameter is tolerance 0.01mm, axis hole A6 and between axis hole D11 center line and inclined-plane 8 error of perpendicularity value can control within 0.01mm, thus make the part processed more meet designing requirement, guarantee precision and the quality of part to be processed.
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.
