And a third positioning structure 330 matched with the third curved surface of the clamped workpiece is arranged on the base of the third clamp, as shown in fig. 3. And a fourth positioning structure 340 matched with the fourth curved surface of the clamped workpiece is arranged on the base of the fourth clamp, as shown in fig. 4. A fifth positioning structure 350 matched with the fifth curved surface of the clamped workpiece is arranged on the base of the fifth clamp, as shown in fig. 5. And a sixth positioning structure 360 matched with the sixth curved surface of the clamped workpiece is arranged on the base of the sixth clamp, as shown in fig. 6. And a seventh positioning structure 370 matched with the seventh curved surface of the clamped workpiece is arranged on the base of the seventh clamp, as shown in fig. 7. An eighth positioning structure 380 matched with the eighth curved surface of the clamped workpiece is arranged on the base of the eighth clamp, as shown in fig. 8.

The first fixture is taken as an example to specifically describe each fixture in the special-shaped curved surface positioning fixture system of the embodiment of the present invention.

As shown in fig. 1 and 9 to 11, the first jig includes a base 100 and a plurality of clamping assemblies 200 disposed on the base 100.

Wherein, a first positioning structure 310 matched with a first curved surface on the clamped workpiece 500 is arranged on the base of the first clamp.

For example, in the present embodiment, the first positioning structure 310 may be a positioning groove. The shape of the locating groove matches the shape of the first curved surface on the clamped workpiece 500 so that the first curved surface on the clamped workpiece 500 can be placed in the first locating structure 310 for locating.

Further, in order to reduce the weight of the fixture and save materials, a hollow structure 400 can be further arranged in the positioning groove. Moreover, the hollow structure 400 can reduce the contact surface between a part of the clamped workpiece 500 and the first positioning structure 310, so that the workpiece can be positioned. In addition, through setting up hollow out construction 400 can make things convenient for the removal of tool bit, reduce the wearing and tearing of anchor clamps or tool bit that tool bit and anchor clamps direct contact caused to increase anchor clamps, tool bit's life.

Further, as shown in fig. 9, 2 reference holes 120 are provided in the base 100. Because the clamped workpiece 500 is a curved surface type special-shaped part, the alignment is difficult, and the alignment is carried out by adopting 2 reference holes, so that the data transmission is convenient and accurate.

Wherein a plurality of clamping assemblies 200 are disposed about the first positioning structure 310, as shown in fig. 1.

Illustratively, as shown in fig. 9, 10, and 11, the clamping assembly includes a compression bar 210 and an adjustable pressure plate 220. A strip-shaped hole 221 is provided on the adjustable pressure plate 220. One end of the pressing rod 210 is connected to the base 100, and the other end of the pressing rod 210 penetrates through the strip-shaped hole 221.

Specifically, the base 100 is provided with a mounting hole 110. A sleeve 240 is disposed in the mounting hole 110 in an interference fit. The compression rod 210 is removably attached to the sleeve 240 by a threaded connection. In use, the clamped workpiece 500 is placed on the fixture and clamped by the adjustable pressing plate 220, and after the workpiece is machined, the adjustable pressing plate 220 is released to take out the clamped workpiece 500. After the long-time use, the mounting hole 110 on the base 100 is worn, and the mounting of the pressing rod 210 is unstable, so that the arranged sleeve 240 can be replaced, the thread in the sleeve 240 is damaged after the long-time use, and the sleeve 240 can be replaced, thereby facilitating the maintenance and reducing the use cost.

Through setting up bar hole 221 on adjustable clamp plate 220, in the use, adjustable clamp plate 220 can move along bar hole 221 at compressing tightly pole 210 to can adjust the clamping position of adjustable clamp plate 220 as required, with the clamping operation of the work piece 500 of the clamp of adaptation different size specifications.

Further, as shown in fig. 11, a rubber washer 230 is provided between the pressing bar 210 and the strip hole 221. The friction force between the pressing rod 210 and the adjustable pressing plate 220 can be increased by arranging the rubber gasket 230 between the pressing rod 210 and the strip-shaped hole 221, so that the pressing effect of the adjustable pressing plate 220 is stable.

Further, as shown in fig. 10, a groove 222 is provided on the adjustable pressing plate 220 on the side contacting the clamped workpiece. A rubber pad 250 is disposed in the groove 222. The rubber pad 250 is arranged on the side, which is in contact with the clamped workpiece, of the adjustable pressure plate 220, so that in the process of clamping the clamped workpiece 500, the friction force between the adjustable pressure plate and the clamped workpiece 500 can be increased, the clamping effect is stable, and the abrasion of the clamped workpiece 500 caused by direct contact between metals can be effectively avoided.

The utility model discloses the structure of second anchor clamps to eighth anchor clamps among dysmorphism curved surface positioning fixture system and the main difference of above-mentioned first anchor clamps lie in, and the location structure on the base is different in second anchor clamps to the eighth anchor clamps to location structure also diverse on the base between second anchor clamps to the eighth anchor clamps, be provided with promptly on the base of second anchor clamps with by the first location structure 320 of the second curved surface assorted of tight work piece, as shown in FIG. 2. And a third positioning structure 330 matched with the third curved surface of the clamped workpiece is arranged on the base of the third clamp, as shown in fig. 3. And a fourth positioning structure 340 matched with the fourth curved surface of the clamped workpiece is arranged on the base of the fourth clamp, as shown in fig. 4. A fifth positioning structure 350 matched with the fifth curved surface of the clamped workpiece is arranged on the base of the fifth clamp, as shown in fig. 5. And a sixth positioning structure 360 matched with the sixth curved surface of the clamped workpiece is arranged on the base of the sixth clamp, as shown in fig. 6. And a seventh positioning structure 370 matched with the seventh curved surface of the clamped workpiece is arranged on the base of the seventh clamp, as shown in fig. 7.
