Description
Technical field
A kind of dot matrix loading device, belongs to large-scale key component loading equipemtn technical field.
Background technology
The load test for large-scale key component mainly has two kinds of load modes at present, and oil cylinder is loaded and with reloading.This
Two kinds of load modes can realize concentrated force loading and even distributed force loading, and when on face to bear pressure linear or non-
During linear change, traditional approach can not accurately meet loading and require, it is impossible to react the real working condition during use by testpieces.
Utility model content
Technical problem to be solved in the utility model is to provide one kind and is simple to manufacture, loads convenience, can meet change pressure
The dot matrix loading device of power.
In order to solve the above technical problems, the technical scheme that the utility model is used：A kind of dot matrix loading device, including
Support frame and Duo Gen loading bars, support frame as described above include top location-plate, bottom location-plate, four pieces of risers and Duo Gen connecting poles, described
Top location-plate is arranged on the surface of bottom location-plate, and many connecting poles are vertically arranged between top location-plate and bottom location-plate
For being fixedly connected with top location-plate and bottom location-plate, four pieces of risers are vertically arranged in top location-plate edge and bottom positioning edges of boards
Top location-plate and bottom location-plate are surrounded into an integral frame between edge；
The top location-plate is provided with the insertion array hole for inserting loading bar, is equipped with the corner of the top location-plate
With playing the swivel nut that hanging piece is connected, the bottom location-plate is identical with top positioning plate structure；
The loading bar includes vertical round steel, gag lever post and lifting bolt, and the gag lever post is horizontally set on vertical round steel
Top, the lifting bolt is fixed on the top of vertical round steel vertically.
Described hanging piece is swivel screw.
The course of work of the present utility model is：First according to result of calculation by multiple loading bars insert respectively top location-plate and
In the insertion array hole of bottom location-plate, support frame is then lifted to by the surface in the face of being loaded by swivel screw and delayed
It is slow fall, until all loading bar bottoms are in contact with being loaded face, and need the gag lever post of all loading bars to leave top calmly
Position plate, now the weight of all loading bars born by the face of being loaded, after loaded by swivel screw will support
Frame hangs the face of being loaded.
Compared to the prior art the utility model has the advantages that.
First, the utility model is divided into some grids by that will be loaded face, extracts the pressure value of each grid element center, right
Each grid is individually loaded, then top location-plate and bottom location-plate are both designed as into insertion battle array corresponding with loading area grid
Row pore structure, the mode being fitted thus by dot matrix, the utility model can both meet the loading demand of even distributed force, can also be real
Existing pressure linearly distribution or nonlinear Distribution or the loading being distributed by other rules, load test is accurate, can react subject
Test the real working condition during use of part.
2nd, lifting bolt is mounted at the top of every loading bar of the utility model, for loading bar lifting insertion to be supported
In the insertion array hole of frame, the different loading bar of length is changed in face of different on-load pressure values, installs and changes convenient, fit
Answering property is good, and loading bar is installed in advance, with support frame integral lifting, and test period is short, and operating efficiency is high.
3rd, of the present utility model hanging piece selects swivel screw, the swivel spiral shell during support frame is lifted by crane
The top suspension ring of nail make adaptability rotation with Impact direction, and stress equalization, test effect is good.

Embodiment
As Figure 1-Figure 4, a kind of dot matrix loading device, including support frame 9 and Duo Gen loading bars 10, support frame as described above
9 include top location-plate 1, bottom location-plate 5, four pieces of risers 4 and Duo Gen connecting poles 2, and the top location-plate 1 is arranged on bottom location-plate 5
Surface, many connecting poles 2 be vertically arranged in top location-plate 1 and bottom location-plate 5 between be used for be fixedly connected top positioning
Plate 1 and bottom location-plate 5, four pieces of risers 4 are vertically arranged between the top edge of location-plate 1 and the edge of bottom location-plate 5 that top is fixed
Position plate 1 and bottom location-plate 5 surround an integral frame；
The top location-plate 1 is provided with the insertion array hole for inserting loading bar 10, equal in the corner of the top location-plate 1
Provided with playing the swivel nut 3 that hanging piece 11 is connected, the bottom location-plate 5 is identical with the top structure of location-plate 1；
The loading bar 10 includes vertical round steel 6, gag lever post 7 and lifting bolt 8, and the gag lever post 7 is horizontally set on perpendicular
The top of straight round steel 6, the lifting bolt 8 is fixed on the top of vertical round steel 6 vertically.
It is preferred that, described hanging piece 11 is swivel screw.
The bottom location-plate 5 and top location-plate 1 size determined by the loading area size for being loaded face 12, array
The spacing and size in hole require determination according to pressure change gradient and loading accuracy, for example, be loaded the loading area area in face 12
For 800mm × 800mm, 100mm × 100mm grid is divided into, totally 64 grids, the pressure value of each grid is extracted, the bottom of by
Location-plate 5 and top location-plate 1 are sized such that on 900mm × 900mm, bottom location-plate 5 and top location-plate 1 that correspondence loading area is provided with
64 Φ 82 through hole.
The diameter of round steel 6 of the loading bar 10 determines by the size of insertion array hole of bottom location-plate 5 and top location-plate 1,
For example when being provided with 64 Φ 82 through hole on bottom location-plate 5 and top location-plate 1, then a diameter of Φ 80 of round steel 6, due to round steel 6
Weight be the correspondence net region loading pressure value, in the case where the diameter of round steel 6 is certain, i.e., the length of round steel 6 with should
Pressure value at grid is directly proportional change；
The present apparatus, which can be applied, is used for plane, inclined-plane, the loading of curved surface, and application is strong.
Above-described embodiment is the explanation to the utility model structure and unrestricted, is not departing from the utility model principle premise
Lower made deformation is also within protection domain of the present utility model.
