The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Referring to Fig. 1～3,10 and 11, the embodiment of the invention is provided with base 1, upper cover plate 2, unidirectional hydraulic cylinder 3, piezoelectric ceramics 4, left socle 5, right support 6, hydraulic cylinder clamping support 7, back-moving spring 8, locking hydraulic cylinder 9, fixedly jacking block 10, screw 11, oil cylinder 12, filter 13, oil pump 14, choke valve 15, overflow valve 16 and reversal valve 17.Wherein, upper cover plate 2 covers on base 1, and unidirectional hydraulic cylinder 3 one ends are installed on the base 1, and an end passes upper cover plate 2 and is exposed and pastes piezoelectric ceramics 4; Oil cylinder 12, filter 13, oil pump 14, choke valve 15, overflow valve 16 and unidirectional hydraulic cylinder 3 are formed a hydraulic circuit, are used to control the motion of unidirectional hydraulic cylinder 3; Left socle 5, right support 6 all are fixed on the base 1; Hydraulic cylinder clamping support 7 is installed in left socle 5, the right support 6; Locking hydraulic cylinder 9 is installed on the base 1, and oil cylinder 12, filter 13, oil pump 14, choke valve 15, overflow valve 16, reversal valve 17 and locking hydraulic cylinder 9 have also constituted another hydraulic circuit, flexible with control locking hydraulic cylinder 9; When 9 elongations of locking hydraulic cylinder, can promote hydraulic cylinder clamping support 7 and move right, clamp unidirectional hydraulic cylinder 3, and compression reseting spring 8; Back-moving spring 8 is installed in the middle of hydraulic cylinder clamping support 7 and the right support 6, and when 9 withdrawals of locking hydraulic cylinder, compressed back-moving spring 8 can push back hydraulic cylinder clamping support 7 left; Fixedly jacking block 10 is installed on the upper cover plate 2 by screw 11, is used to grip free curve surface work pieces P to be measured.
As shown in figure 10, during work, start oil pump 14 earlier,, behind fluid process filter 13 and the choke valve 15, enter in the unidirectional hydraulic cylinder 3, unidirectional hydraulic cylinder 3 jack-up from 12 li oil suctions of oil cylinder.Unidirectional hydraulic cylinder 3 is placed on workpiece on the unidirectional hydraulic cylinder 3 after being elongated to the height that needs.Unidirectional hydraulic cylinder 3 is because of the extruding of workpiece gravity, and pressure rises.When pressure surpassed the force value of overflow valve 16 settings, overflow valve 16 was opened, and fluid in the unidirectional hydraulic cylinder 3 and oil pump 14 draw up the fluid that comes and flow in the oil cylinder 12 through overflow valve 16.Behind the gravity of balance workpiece, unidirectional hydraulic cylinder 3 stop motions.At this moment, the unidirectional hydraulic cylinder 3 that supports free curve surface work pieces to be measured can contact with this surface of the work fully, and therefore, the workpiece of any bottom shape can be placed in the present invention steadily.At this moment, open the oil pump 14 among Figure 11, and reversal valve 17 is got to right position, fluid is from oil cylinder 12, behind filter 13 and choke valve 15, flow to the right position of reversal valve 17, and then enter the left chamber of locking hydraulic cylinder 9, and from locking the right chamber realization oil return of hydraulic cylinder 9, therefore lock hydraulic cylinder 9 elongations, promote hydraulic cylinder clamping support 7 and move right, and clamp unidirectional hydraulic cylinder 3 by the V-arrangement bayonet socket A on the hydraulic cylinder clamping support 7, and compression reseting spring 8, shown in Fig. 2～4.Therefore, even when having external force to act on this workpiece downwards,, therefore can not cause this workpiece to produce downward displacement because it is clamped to support the unidirectional hydraulic cylinder 3 of this workpiece.Then, withstand this workpiece, and, as shown in Figure 1, can realize the location of this workpiece is clamped work with screw 11 lockings by fixing jacking block 10.When needs unclamp unidirectional hydraulic cylinder 3, reversal valve 17 is got to position, a left side, the flow through left side position of choke valve 15 and reversal valve 17 of fluid, enter the right chamber of locking hydraulic cylinder 9, and from locking the left chamber realization oil return of hydraulic cylinder 9, therefore lock hydraulic cylinder 9 withdrawals, compressed back-moving spring 8 can push back hydraulic cylinder clamping support 7 left.
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, hydraulic cylinder 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 hydraulic cylinder 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 hydraulic cylinder 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 hydraulic cylinder clamping support 7 also fit together, as shown in Figure 8.
As shown in Figure 9, when a plurality of positioning fixture structures to form together the time, have only the positioning fixture in the lower left corner that locking hydraulic cylinder 9 need be installed, other positioning fixture does not need to install locking hydraulic cylinder 9.When the locking hydraulic cylinder 9 of the positioning fixture of tightening the lower left corner, the hydraulic cylinder clamping support 7 that locking hydraulic cylinder 9 can promote in these positioning fixtures moves right.Because the hydraulic cylinder clamping support 7 of the positioning fixture of splicing also is splicing mutually mutually, as shown in Figure 8, when the hydraulic cylinder clamping support 7 in the lower left corner moved right, the hydraulic cylinder clamping support 7 that can promote the right side also moved right.Same, because adjacent two rows' in front and back hydraulic cylinder clamping support 7 head and the tail are combined together, so the hydraulic cylinder clamping support 7 that can drive last row that moves right of this row's hydraulic cylinder clamping support 7 equally synchronously moves right, thereby, moving right of the hydraulic cylinder clamping support 7 of the positioning fixture in the lower left corner, driven moving right synchronously of all hydraulic cylinder clamping support 7 that is stitched together, thereby clamped all unidirectional hydraulic cylinders 3, realized location thus this workpiece for measurement.At last, withstand this workpiece, 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.
After workpiece is located by this invention clamping, can make piezoelectric ceramics 4 extend piezoelectric ceramics 4 energisings of pasting on the unidirectional hydraulic cylinder 3, realize being placed on the fine position of the workpiece above the piezoelectric ceramics 4, realize pinpoint purpose with this.
