Embodiment
Below in conjunction with embodiment, the utility model is further illustrated.
See Fig. 1-6, the secondary framework device for testing stiffness of U-shaped, comprises left backstay 1, right backstay 2, the sliding beam 3 connecting two bars, positioning seat 5 and dial gauge 6; Also comprise L shape mount pad 4; The widthwise edge of L shape mount pad 4 is provided with draw-in groove 4.1, and dial gauge 6 is placed in draw-in groove 4.1; The longitudinal edge of L shape mount pad 4 is connected with sliding beam 3; Positioning seat 5 one end is provided with U-shaped mouth 5.1, and the other end is provided with end plate 5.2; The push rod 6.1 of dial gauge 6 contacts with end plate 5.2.
Left backstay 1, right backstay 2 are respectively equipped with left bar elongated hole 1.2, right bar elongated hole 2.2.
Sliding beam 3 is provided with three sliding beam elongated holes 3.1.Form an adjustable sliding beam, by regulating the length of left backstay 1, right backstay 2 and sliding beam 3, to adapt to the test of the secondary framework of different gauge U-shaped.
The longitudinal edge of L shape mount pad 4 is provided with mount pad elongated hole 4.2.The height of adjustable left backstay 1, right backstay 2 and sliding beam 3, to adapt to the test of the different tested point of the secondary framework of U-shaped.
Each web member all has elongated hole, facilitates position adjustments, connect and fix all with bolts.
This device up and down height in direction and width can move adjustment, ensure that the test of the secondary framework of the U-shaped of different gauge, wheelbase, and the secondary framework of U-shaped of reply different model, only need fix by free adjustment bolt in each elongated hole.
The end plate 5.2 of positioning seat 5, also by positioning seat elongated hole 5.4 free adjustment, when doing transverse direction, longitudinal rigidity test, only need adjust the direction of the push rod 6.1 of dial gauge 6.
Left backstay 1, right backstay 2 are connected and fixed with the left and right side saddle viewport of the secondary framework 7 of U-shaped by respective left bar bolt 1.1, right bar bolt 2.1, and sliding beam 3 is joined with bolts with the left bar elongated hole 1.2 on left and right backstay 1,2, right bar elongated hole 2.2 by the beam length hole 3.1 at two ends; The longitudinal edge of L shape mount pad 4 is joined with bolts by vertical direction with the beam length hole 3.1 in the middle of sliding beam 3 by its mount pad elongated hole 4.2, dial gauge 6 is arranged in the draw-in groove 4.1 of L shape mount pad 4 widthwise edge, by being screwed into screws clamp dial gauge 6 in mount pad screw 4.3; Positioning seat 5 is fixed on central sill (tested point) place of the secondary framework 7 of U-shaped by its U-shaped mouth 5.1, is screwed into screw fixes at positioning seat screw 5.3; End plate 5.2 and dial gauge 6 push rod 6.1 of positioning seat 5 are adjacent to.
L shape mount pad 4 adjusts installation site by mount pad elongated hole 4.2 movement up and down, and positioning seat 5 is fixed on the secondary framework 7 measuring point place of U-shaped by screw, obtains the deflection of the secondary framework tested point of U-shaped relative to left and right sides saddle by the numerical value of dial gauge 6.
When carrying out U-shaped pair framework rigidity test, the end plate 5.2 of positioning seat 5 is adjacent to rear clearing with the push rod 6.1 of dial gauge 6, records the reading of the secondary framework of U-shaped dial gauge 6 under each operating mode successively, thus obtains the rigidity value of the secondary framework of U-shaped.Measurement direction for its horizontal and vertical rigidity is different, only need convert installation direction and the position of dial gauge 6.
