Description

One kind is used for the hot forming complex curved surface parts accurate cutting clamper of water knife

Technical field

The utility model is related to a kind of fixture accurately cut for hot forming complex curved surface parts, belongs to metal machinery and adds Construction equipment technical field.

Background technology

Hot forming is the forming technology of most of sheet metal component in aerospace field, and to the accurate cutting of hot forming blank It is a wherein very important procedure, it determines the dimensional accuracy of final part.In the prior art, due to the complexity of part Property, it is necessary to multiple cutting clamper positions the cutting starting point of different parts, process costs are high and process cycle is long.

Utility model content

The purpose of this utility model is to provide a kind of low cost and can accomplish multi-direction positioning, the use of multi-angle cutting In the fixture that hot forming complex curved surface parts water knife accurately cuts.

To achieve the above object, the utility model is adopted the following technical scheme that：One kind is used for hot forming complex curved surface parts The accurate cutting clamper of water knife, the fixture is hexahedron, and its upper surface is type face；Left and right end face is datum plane；In bottom surface Portion is inclined-plane.

Preferably, groove is provided with the fixture, the groove runs through left and right end face.

Preferably, the front and rear surfaces of the fixture are type face.

Fixture upper surface is type face, for positioning complex curved surface parts left and right directions；Fixture front and rear surfaces are type face, are used for Position the fore-and-aft direction of complex curved surface parts；Plane on the basis of fixture left side, for positioning left end cutting starting point；Fixture is right Plane on the basis of end face, for positioning right-hand member cutting starting point；Fixture bottom surface middle part is inclined-plane, for coordinating right side.

The utility model has the advantages that：Simple structure, it is easy to use, and can realize to complex curved surface parts Be accurately positioned；Can multi-angle, it is multi-direction to put fixture to facilitate cutting.

Fig. 2 is the schematic diagram for cutting initial point relative position from left to right；

Fig. 3 is the schematic diagram for cutting initial point relative position from right to left.

Specific embodiment

The utility model is further described below in conjunction with the accompanying drawings：

As shown in figure 1, a kind of be used for the hot forming complex curved surface parts accurate cutting clamper of water knife, the cutting clamper 10 is Hexahedron with the groove through left and right end face, it has 101 right-hand member datum planes, 102 left end datum planes, 103 bottom surfaces Horizontal base plan, 104 bottom surface inclined-plane datum planes, type face above 105.

As shown in Figure 2,3, blank is positioned on fixture, makes to be alignd at the knuckle of center, left and right two sides is tight with fixture 10 Laminating.

As shown in Fig. 2 being bottom surface with 103 using plane on the basis of 102 and 103 faces during 11 left side 111 of cutting parts Benchmark, is left side benchmark with 102 datum planes, at the plane A distances of distance 102, is cut with a vertical α angle feeds Cut.

As shown in figure 3, being bottom surface with 104 using plane on the basis of 101 and 104 faces during 11 right side 112 of cutting parts Benchmark, is right side benchmark with 101 datum planes, at the plane B distances of distance 101, vertical feed cutting.

In description of the present utility model, term " on ", D score, "front", "rear", the orientation of instruction such as "left", "right" or Position relationship is, based on orientation shown in the drawings or position relationship, to be for only for ease of description the utility model and simplify description, Rather than indicate imply signified device or element must have specific orientation, with specific azimuth configuration and operation, because This is it is not intended that to limitation of the present utility model.
