Detailed description of the invention

For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail detailed description of the invention of the present utility model below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar improvement without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public concrete enforcement.

The fixture 100 of an embodiment as shown in Figure 1, for the processing of workpiece 200.

Workpiece 200 can be middle plate or the base plate of mobile terminal device.

Fixture 100 comprises: base plate 10, cylinder 20 and fixture bed die.

Cylinder 20 is multiple, and multiple cylinder 20 is arranged on base plate 10 around fixture bed die, and cylinder 20 is provided with cylinder paw 22 away from one end of base plate 10, and cylinder 20 is for driving cylinder paw 22 to press down thus clamping work pieces 200.

Composition graphs 1, in present embodiment, cylinder 20 is six, and six cylinders 20 are arranged around fixture bed die.

Concrete, base plate 10 is rectangle, and two long limits of base plate 10 are respectively provided with two cylinders 20, and two minor faces of base plate 10 are respectively provided with a cylinder 20.

Fixture bed die is arranged on the middle part of base plate 10, and fixture bed die is for carrying workpiece 200.

In present embodiment, fixture bed die is arranged on the middle part of base plate 10 by back-up block 31.In other implementations, back-up block 31 can omit.

Composition graphs 1, fixture bed die comprises substrate 32 and is arranged on the multiple spacing holes 34 on a surface of substrate 32, and spacing hole 34 is for fixing locating part, and locating part is for limiting the movement of workpiece 200 in substrate 32 place plane.

Concrete, locating part can be pin.

Composition graphs 2, the fixture bed die 330 of another embodiment, comprises substrate 332, spacing hole 334 and benchmark contact block 336.Spacing hole 334 is for fixing locating part, and locating part is for limiting the movement of workpiece in substrate 332 place plane.Benchmark contact block 336 and multiple spacing hole 334 are arranged on the same surface of substrate 332, and multiple spacing hole 334 is arranged on the periphery of benchmark contact block 336.Benchmark contact block 336 is the reference contact faces with absorption surface away from the end face of one end of substrate 336.

This fixture bed die 330 by arranging benchmark contact block 336 on substrate 332, benchmark contact block 336 is formed with the reference contact faces of absorption surface less relative to the surface of whole substrate 332 away from the end face of one end of substrate, is convenient to the calibration of the flatness of reference contact faces.
