The invention provides a kind of spring piece structure positioning fixture that is applicable to free curve surface work pieces, be used at different size, shape, the free curve surface work pieces of especially different bottom shapes is realized location, the designing requirement that clamps.Compare with existing positioning fixture, the present invention has following outstanding feature:
1) has the advantages that versatility is good, positioning accuracy is high, easy to use, can realize that the location of the free curve surface work pieces of different surfaces shape clamps.Because the present invention has adopted the location structure of dot matrix contact, when free curve surface work pieces to be measured was placed on this structure, the weight of free curve surface work pieces can be oppressed thimble compressive load spring, and moves downward.When lock-screw is tightened, can promote the thimble clamping support thimble is clamped, play the purpose of location thus.Therefore can realize the different surfaces shape, the location of the free curve surface work pieces of especially different bottom shapes.
2) adopt the assembled piece type structure, can realize that the location of the free curve surface work pieces of different size clamps.Because of adopting erection method, a plurality of positioning fixtures can be spliced into the large scale structure, but the clamping size is big, clamp so can realize the location of the free curve surface work pieces of different size.
3) easy to use, the positioning accuracy height.The present invention only needs to be placed on free curve surface work pieces to be measured on this positioning fixture, puts level or is placed on the position that needs, and tightens lock-screw, can realize the accurate location of free curve surface work pieces, therefore have easy to use, the characteristics that positioning accuracy is high.

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Referring to Fig. 1～3, the embodiment of the invention is provided with base 1, upper cover plate 2, thimble 3, spring loaded 4, left socle 5, right support 6, thimble clamping support 7, back-moving spring 8, lock-screw 9, fixedly jacking block 10 and screw 11.Wherein, upper cover plate 2 is installed on the base 1; Thimble 3 passes spring loaded 4 and is installed on the upper cover plate 2; Left socle 5, right support 6 all are fixed on the base 1; Thimble clamping support 7 is installed in left socle 5, the right support 6; Lock-screw 9 is installed on the base 1, and when tightening lock-screw 9, can promote thimble clamping support 7 and move right, and compression reseting spring 8; Back-moving spring 8 is installed in the middle of thimble clamping support 7 and the right support 6, and when unclamping lock-screw 9, compressed back-moving spring 8 can push back thimble clamping support 7 left; Fixedly jacking block 10 is installed on the upper cover plate 2 by screw 11, is used for gripping free curve surface work pieces to be measured.
During work, free curve surface work pieces P to be measured is placed on the thimble 3; Because the cause of free curve surface work pieces P gravity to be measured, thimble 3 can move downward by compressive load spring 4, behind this gravity of balance, and just stop motion.At this moment, the thimble 3 that supports free curve surface work pieces P to be measured can contact with this workpiece P surface fully, and therefore, the workpiece of any bottom shape can be placed in the present invention steadily.When tightening lock-screw 9, lock-screw 9 can promote thimble clamping support 7 and move right, and clamps thimble 3 by the V-arrangement bayonet socket A on the thimble clamping support 7, as shown in Figure 4.Therefore, even when having external force to act on this workpiece P downwards, because it is clamped to support the thimble 3 of this workpiece, so can not cause this workpiece to produce downward displacement.Then, withstand this workpiece, and, as shown in Figure 1, can realize the location of this workpiece P is clamped work with screw 11 lockings by fixing jacking block 10.
When free curve surface work pieces size to be measured is big, can realize that the location of large-size workpiece clamps work by splicing to a plurality of positioning fixture structures.Specific implementation method is:
As shown in Figure 5, have two faces to be provided with draw-in groove B on the base 1 of the embodiment of the invention, two faces are provided with fixture block C in addition, when several base splicings, the face of the mutual applying of adjacent pans 1 is realized the cooperation of fixture block C and draw-in groove B, thereby realizes the splicing of a plurality of bases 1, as shown in Figure 6.Same, as shown in Figure 7, thimble clamping support 7 one ends of embodiment of the invention fluting D, when adjacent two rows' in front and back positioning fixture respective outer side edges, adjacent two thimble clamping supports 7 realize that head and the tail cooperate.Because the left and right sides width of the left and right sides width of thimble clamping support 7 and base 1 is the same, so when adjacent two rows' in the left and right sides the base 1 of positioning fixture was stitched together, adjacent two rows' in the left and right sides thimble clamping support 7 also fit together, as shown in Figure 8.
As shown in Figure 9, a plurality of positioning fixture structures to form have only the positioning fixture in the lower left corner that lock-screw 9 need be installed together the time, and other positioning fixture does not need to install lock-screw 9.When the lock-screw 9 of the positioning fixture of tightening the lower left corner, the thimble clamping support 7 that lock-screw 9 can promote in these positioning fixtures moves right.Because the thimble clamping support 7 of the positioning fixture of splicing also is splicing mutually mutually, as shown in Figure 8, when the thimble clamping support 7 in the lower left corner moved right, the thimble clamping support 7 that can promote the right side also moved right.Same, because adjacent two rows' in front and back thimble clamping support 7 head and the tail are combined together, so the thimble clamping support 7 that can drive last row that moves right of this row's thimble clamping support 7 equally synchronously moves right, therefore, moving right of the thimble clamping support 7 of the positioning fixture in the lower left corner, driven moving right synchronously of all thimble clamping supports 7 of being stitched together, thereby clamped all thimbles 3, realized location thus this workpiece for measurement.At last, withstand this workpiece P, and, as shown in Figure 9, can realize the location of this workpiece is clamped work with screw 11 lockings by fixing jacking block 10.
