As the important composition unit of propellant tank bottom, its spheroid shape face mainly adopts the side of drawing and forming to melon lobe
Formula, the melon lobe after molding is the poor Thin Elastic wall pieces of rigidity, and its theoretical surface profile is the big quadratic surface of area.Due to
The difficult point such as its poor rigidity, clamping, location difficulty, wall thickness dimension be wayward, for a long time, governs the processing of melon lobe part always
Quality and the lifting of working (machining) efficiency.
Melon lobe workpiece belongs to typical space curved surface thin-walled parts, has the characteristics that thin-walled and poor rigidity two are prominent, this
It is the subject matter of the required solution when positioning to it, clamping.The required precision of melon lobe workpiece weakened region thickness makes
Frock must possess enough rigidity；And the course of processing of workpiece weakened region, it is also the process of residual stress release simultaneously, gesture
The rule that the different degrees of deformation of workpiece generation, the size degree of deformation and position have no predictability must be caused can to follow, therefore,
Moment ensures that workpiece is fitted with clamp body and requires frock must possess enough flexibilities, and that is, chucking power can be according to part shape
Localized variation can make uniform, adaptive adjustment, how to solve this " one upon soft " becomes the key of jig Design.
And traditional positioning for curved surface parts such as melon lobes, clamping use curved rigid surfaces to position, its basic skills
It is by the means of machining, rigidity positioning supporting surface corresponding with surface of the work to be processed on frock, using pressing plate, arc
The clamping means such as shape press strip, the deformation segmentation according to single part or subregion processing weakened region, for numerical control
For processing, subregion processing cannot take into account efficiency, meanwhile, different according to region division degree, the processing journey of same part
Sequence is also not quite identical, cannot solidify, and causes crudy also to cannot get stable control.

Air drain, passage is connected with negative pressure subsystem by pipeline subsystem, is provided with ring packing in air channel and passage outer week
Groove, correspondence preferably uses the round cross section sealing bar of Φ 7, by the sealing function of sealing strip and negative pressure subsystem evacuation, makes melon
The airtight intracavity that lobe loose tool clamp body and workpiece to be processed are formed produces vacuum, relies on atmospheric pressure to clamp workpiece to be processed,
Thus realizing the positioning to melon lobe workpiece to be processed, supporting and clamping.
This utility model clamping workpiece by the way of vac sorb, can be with the uneven problem of effectively solving chucking power；
Secondly, clamping workpiece by the way of vac sorb, chucking power can make adaptive adjustment according to the deformation degree of workpiece,
Avoid workpiece and clamp body surface generation gap, meanwhile, workpiece is fitted with the height of clamp body and can effectively be alleviated machining
During cutter problem of trembling, be conducive to improving the stability of whole cutting process.
Compared with prior art, the utility model has the advantage of：This utility model passes through to construct corresponding positioning support
Face is positioning, to support workpiece, and clamping workpiece by the way of vac sorb, it is preferred to use arc press strip cooperation regulating bolt,
Workpiece fixed by alignment pin, not only can the positioning of effectively solving workpiece, supporting, the key technical problem of clamping, meanwhile, workpiece and
The high laminating degree of clamp body can effectively alleviate the problem of trembling of cutter in cutting process, is conducive to improving whole cutting
The stability of the course of processing.Therefore, this utility model has convenient mounting and clamping, accurate positioning, the uniform advantage of chucking power.
