Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described.
See Fig. 16, U-shaped pair framework device for testing stiffness, including left location bar 1, right location bar 2, connect the cunning of two bars
Dynamic beam 3, positioning seat 5 and dial gauge 6；Also include L-shaped mounting seat 4；The widthwise edge of L-shaped mounting seat 4 is provided with draw-in groove 4.1, dial gauge 6
It is placed in draw-in groove 4.1；The longitudinal edge of L-shaped mounting seat 4 is connected with sliding beam 3；Positioning seat 5 one end is provided with U-shaped mouth 5.1, the other end
It is provided with end plate 5.2；The push rod 6.1 of dial gauge 6 contacts with end plate 5.2.
Left bar elongated hole 1.2, right bar elongated hole 2.2 it is respectively equipped with on left location bar 1, right location bar 2.
Sliding beam 3 is provided with three sliding beam elongated holes 3.1.Form an adjustable sliding beam, by regulating left location bar
1, right location bar 2 and the length of sliding beam 3, to adapt to the test of different gauge U-shaped pair framework.
The longitudinal edge of L-shaped mounting seat 4 is provided with mounting seat elongated hole 4.2.Scalable left location bar 1, right location bar 2 and slip
The height of beam 3, to adapt to the test of U-shaped pair framework difference tested point.
All have elongated hole on each connector, facilitate position adjustments, connect and fix the most with bolts.
Height and the width in this device direction up and down can move regulation, it is ensured that different gauge, the U-shapeds of wheelbase
The test of secondary framework, the U-shaped pair framework of reply different model, only need to freely regulate bolt in each elongated hole and fix.
The end plate 5.2 of positioning seat 5 freely regulates also by positioning seat elongated hole 5.4, do laterally, longitudinal rigidity test time,
Only need to adjust the direction of the push rod 6.1 of dial gauge 6.
Left location bar 1, right location bar 2 by respective left bar bolt 1.1, a left side for right bar bolt 2.1 and U-shaped pair framework 7,
Right side saddle observation port connects fixing, and sliding beam 3 is by the beam length hole 3.1 at two ends and the left bar elongated hole on left and right location bar 1,2
1.2, right bar elongated hole 2.2 is joined with bolts；The longitudinal edge of L-shaped mounting seat 4 is by its mounting seat elongated hole 4.2 and sliding beam 3
Middle beam length hole 3.1 is joined with bolts in a vertical direction, and dial gauge 6 is arranged on the draw-in groove of L-shaped mounting seat 4 widthwise edge
In 4.1, by being screwed into screws clamp dial gauge 6 in mounting seat screw 4.3；Positioning seat 5 is fixed on U-shaped by its U-shaped mouth 5.1
Central sill (tested point) place of secondary framework 7, is screwed into screw at positioning seat screw 5.3 and fixes；End plate 5.2 and the dial gauge 6 of positioning seat 5
Push rod 6.1 is adjacent to.
L-shaped mounting seat 4 adjusts installation site by mounting seat elongated hole 4.2 movement up and down, and positioning seat 5 passes through spiral shell
Nail is fixed at U-shaped pair framework 7 measuring point, obtains U-shaped pair framework tested point relative to left and right sides saddle by the numerical value of dial gauge 6
Deflection.
When carrying out U-shaped pair framework rigidity test, the end plate 5.2 of positioning seat 5 resets after being adjacent to the push rod 6.1 of dial gauge 6,
Record U-shaped pair is framed in the reading of dial gauge 6 under each operating mode successively, thus obtains the rigidity value of U-shaped pair framework.Horizontal for it
Different to the measurement direction with longitudinal rigidity, only need to convert installation direction and the position of dial gauge 6.
