Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the present invention is described in further details.
As shown in Figures 1 to 7, the track traffic product cabinet general comprehensive test fixture of the present embodiment, including a pair folder
Board component 1, a pair cleat assembly 1 constitutes the located space of product cabinet 2, folder between left and right between layout, a pair cleat assembly 1
Board component 1 includes horizontal plate 11 and vertical plate 12, and horizontal plate 11 is provided with the first connection for being connected with all-around test stand 3
Hole 111, vertical plate 12 includes body 121 and the installation portion 122 extended to located space, and installation portion about 122 two ends are all provided with
Have least one set for installing the second connecting hole 123 of product cabinet 2, the quantity of same group of the second connecting hole 123 be two with
Going up and arrange along the vertical direction, this track traffic product cabinet general comprehensive test fixture, its horizontal plate 11 is by the first connection
Hole 111 is fixing with all-around test stand 3 to be connected, and vertical plate 12 is arranged to the installation portion 122 of located space extension for installing
Product cabinet 2, it is ensured that lift bottom product cabinet 2, installation portion about 122 two ends arrange plural second connecting hole
123, it is suitable for the product cabinet 2 that bolt position at differing heights, corner is different, simple in construction, easy to adjust, the scope of application
Extensively.
Referring specifically to Fig. 2 and Fig. 7, the quantity of same group of the second connecting hole 123 is multiple and is equally spaced, two pieces, left and right
Being additionally provided with a pair fine setting cushion block 5 between horizontal plate 11, finely tune cushion block 5 upper surface level, fine setting cushion block 5 lower surface is in rear and front end
It is respectively equipped with one group of cascaded surface 51, at each cascaded surface 51, is equipped with the 3rd connecting hole 52 for being connected with all-around test stand 3,
Spacing between former and later two mutually level cascaded surfaces 51 is d1, on all-around test stand 3 before and after the most adjacent two bolts it
Between spacing be d2, d1=nd2, n are positive integer, by selecting two cascaded surfaces 51 before and after a certain height to put down with compbined test
Bolt on platform 3 coordinates, and can lift product cabinet 2 and highly be finely adjusted, to overcome the second connecting hole 123, product cabinet 2 etc.
Mismachining tolerance and rigging error, simple in construction, governing speed is fast, has higher under the machining accuracy ensureing cascaded surface 51
Adjustment precision, when, after product cabinet 2 and the second connecting hole 123 distribution, having gap bottom product cabinet 2 and between fine setting cushion block 5
Or when needing the height ability distribution turning down product cabinet 2, movable fine setting cushion block 5 selects different cascaded surfaces 51, with reality
What existing both sides were different lifts height；Two adjacent second connecting hole 123 discrepancy in elevation are h1, the maximum discrepancy in elevation between two cascaded surfaces 51
For h2, h2 ＜ h1, i.e. when the scope needing fine setting is excessive, then change the second different connecting holes 123 and product cabinet 2 four jiaos
The bolt at place coordinates.In the present embodiment, on all-around test stand 3, the distance of former and later two bolts is 100mm, i.e. d2=100mm,
The width of the hexagonal (hexagon)nut of bolt head is 24mm, and the height arranging same group of cascaded surface 51 reduces and adjacent two ladders successively
The discrepancy in elevation in face 51 is equal, n=1, i.e. d1=d2=100mm, and the length and width size of each cascaded surface 51 correspondence is 25mm(can not be little
Width in nut), it is provided with quadravalence with group cascaded surface 51, rear to front thickness is followed successively by 24mm, 22mm, 20mm and 18mm,
Big discrepancy in elevation h2=24mm-18mm=6mm, h1=10mm；The aperture of the second connecting hole 123 is available for the fastening bolt of M6 and passes.At other
In embodiment, when on all-around test stand 3, the distance of former and later two bolts becomes the width of the stud greatly or on all-around test stand 3
Time less, may be designed as more multistage.
In the present embodiment, the 3rd connecting hole 52 is counterbore, coordinates sunk screw to be used for being fastened with beneficially and keeps fine setting cushion block 5
Upper surface smooth.
In the present embodiment, installation portion about 122 two ends are equipped with two group of second connecting hole 123, two group of second connecting hole 123
Arrange in left-right direction and the second high 1/2h1 of connecting hole 123 is organized than another, specifically in the position of one of which the second connecting hole 123
See Fig. 7,123 to the one of left side group of second high 5mm of connecting hole 123 of one group of second connecting hole on right side, namely the second of right side
Connecting hole 123 is positioned in the middle of two the second connecting holes 123 up and down that left side is corresponding, and by moving right, product cabinet 2 can contract
The minimum discrepancy in elevation between neighbouring two the second connecting holes 123 in little left side, further facilitates different from bolt position at corner
Product cabinet 2 mate.
In the present embodiment, the second connecting hole 123 and cascaded surface 51 are all equipped with height and indicate (not shown) so that examination
The personnel of testing can learn the height dimension of product cabinet 2 more intuitively.
Referring specifically to Fig. 6, the first connecting hole 111 is the mounting hole arranged in left-right direction, it is simple to regulation cleat assembly 1 it
Between distance to adapt to the product cabinet 2 of different in width, increase further the scope of application of fixture.In the present embodiment, first even
The wire length connecing the center of circle, two ends, hole 111 is 50mm, namely a pair cleat assembly 1 Breadth Maximum regulated value is 100mm, and first even
Connecing hole 111 be provided with 6 and arrange in 3 × 2 arrays, the adjacent two mounting hole spacing of left and right directions are 50mm, and fore-and-aft direction spacing is
100mm, in other embodiments, quantity and arrangement suitably can adjust according to the specification of horizontal plate 11；The aperture of mounting hole
The fastening bolt being available for M12 passes.
In the present embodiment, between horizontal plate 11 and vertical plate 12, it is installed with reinforcement 4 so that cleat assembly 1 has enough
Rigidity, it is possible to adapting to the stress that applied, body 121 and installation portion 122 lay respectively at reinforcement 4 both sides,
In the present embodiment, horizontal plate 11 and vertical plate 12 are formed by plate bending, reinforcement 4 can use the mode of welding respectively with
Horizontal plate 11 and vertical plate 12 are fixed, and plate and reinforcement 4 preferably employ aluminium alloy.
The using method of the track traffic product cabinet general comprehensive test fixture of the present invention is as follows:
1): time initial, select the cascaded surface 51 of interior thickness to be positioned on the bolt of all-around test stand 3, then by product cabinet
2 are positioned on fine setting cushion block 5；If the hole, location on the journal stirrup 21 on front side of product cabinet 2 and the second nearest connecting hole 123 height
Difference 2mm-4mm, then movable fine setting cushion block 5 regulates lifting highly of product cabinet 2, if the discrepancy in elevation is more than 5mm, makes a pair
Cleat assembly 1 mutually draw close or away from, change to second connecting hole 123 corresponding to another group and again compare, movable
Fine setting cushion block 5, if still suffering from fine error (about 1mm), can pad 1mm plain cushion bottom fine setting cushion block 5 and compensating；Complete product
Securing member is utilized product cabinet 2, fine setting cushion block 5 to be fixed with all-around test stand 3 after the height adjustment of cabinet 2,
2): utilize securing member to be fixed with all-around test stand 3 by horizontal plate 11；
3): utilize the bolt at product cabinet 2 four jiaos to be fixed with vertical plate 12 by product cabinet 2, i.e. complete the installation of fixture, can
Carry out follow-up temperature, humidity and vibration integrated test.
