Abstract
The present invention relates to the technical field of manufacturing frocks, particularly to a flexible combined prestressing clamp having universality for a large-scale wall plate type part. The flexible combined prestressing clamp comprises a group of upper cross beams and lower cross beams, and a plurality of vertical posts which are connected among the upper cross beams and lower cross beams, and the vertical posts, the upper cross beams and the lower cross beams are in combing and connecting relation. An assembly cram frame and a pressure plate assembly can be combined and fixed on the vertical posts, and the vertical posts serve as force bearing points to clamp workpieces and apply prestressing force. The present invention has the advantages that the structure of the flexible combined prestressing clamp has flexible combination capability, and has versatility for the prebending clamping of wall plate workpieces with different shapes.
Description
Technical field:
The present invention relates to worker packing technique field, particularly a kind of flexible combined prestress clamp.
Background technology
In the manufacturing technology of airborne vehicle, the contour peening of large-scale wallboard class sheet metal component is a kind of new forming process, as everyone knows in the clamping that must apply it before shot-peening for the thick skinpiston of this large-scale integral in prestressing force and the shot-peening process.And clamping and to apply prestressed frock be one of key technology of contour peening.Large-scale shot blasting equipment has the rigid frame of a stationary fixture and workpiece, and as its shape of wallboard class part, curvature, the different sizes of workpiece, therefore to the flexible combination ability of anchor clamps, the changing capability of the workpiece of anchor clamps adaptation is just had relatively high expectations.In the prior art anchor clamps commonly used be by with part forming after shape, many groups clamp (or mould tire) that curvature matches part is clamped on the rigid frame of shot blasting equipment, make clamp approach down clamp gradually by bolt then and compress fully down to clamp and wallboard.Test shows that these clamp plate type anchor clamps do not reach expected results, and clamp unclamps squab panel resilience to some extent, and a cover clamp is only limited to a kind of wall panel parts simultaneously, and for the wallboard that shape changes to some extent, this clamp does not possess versatility.
The object of the present invention is to provide a kind of a kind of flexible combined prestress clamp that large-scale wallboard class part is had versatility.
Summary of the invention:
For achieving the above object, the present invention proposes following technical scheme: a kind of flexible combined prestress clamp, can be fixed in the rigid frame, include one group of lower and upper cross-member and be connected a plurality of columns between the crossbeam, it between column and the crossbeam relation of being connected, column and crossbeam can be in planes, also can be not in a plane, column can be vertical with crossbeam, also can out of plumb, cramp frame is arranged for other and Anchor plate kit is capable of being combined is fixed on the column, and is that hard point is with piece-holder with apply prestressing force with the column.Column has at least more than two, as required, can reach more than 20.These anchor clamps can be realized the tangential of wallboard class workpiece and exhibition to the clamping of hyperbolic degree and apply shaping prestressing force.The tangential clamping and the application of force are to adopt the method for 3 press-bendings by being fixed on cramp frame on the column and Anchor plate kit, and the big I of the application of force is arbitrarily adjusted, because column is provided with a plurality of connecting holes, the point of application is random up-down adjustment also.According to the designing requirement of workpiece, on each column, can carry out tangential pre-bending clamping.To the pre-bending clamping, is by the plan-position between integrally-regulated column and the adjacent upright posts for exhibition, and workpiece is realized that exhibition is to the pre-bending clamping.
In order to realize being connected of column and crossbeam, the present invention adopts fixed rack on lower and upper cross-member, axially axially intersecting of slide rail with crossbeam, the two ends of column are connected on the slide rail, the position of the relative crossbeam of slide rail can be regulated, the fixed position of column on slide rail can also be regulated, and realizes that like this column and crossbeam can be in planes, also the flexible combination in a plane not.
The invention has the beneficial effects as follows clamp structure be flexible group and, the pre-bending clamping of difformity wallboard workpiece is had versatility.
Below in conjunction with the embodiment accompanying drawing this invention is described in further detail.
