Embodiment
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
Referring to Fig. 1 and Fig. 2, this test fixture mainly comprises installation panel 1, angle adjustable support and mounting seat 7.Angle adjustable support is fixedly mounted in mounting seat 7, and installation panel 1 is fixedly mounted on angle adjustable support upper end, can be by the angle of the adjustment of angle adjustable support and surface level.Angle adjustable support includes upper bracket 2, lower carriage 6 and connects their angle adjusting mechanisms 3 and dead axle 5.
Mounting seat 7 is connected by 8 bolts with testboard bay 18, and main installed surface 1 is for being connected with testing element.Main installed surface 1 bottom surface and upper bracket 2 are rigidly connected, and upper bracket is two blocks of parallel steel plates.Mounting seat 7 end faces and lower carriage 6 are rigidly connected, and lower carriage is also two blocks of parallel steel plates.Two block plates of upper bracket 2 are inserted between two block plates of lower carriage 6, i.e. both interlocks clamp assembling by angle adjusting mechanism 3 and dead axle 5.The axle center that dead axle rotates around lower carriage as upper bracket, angle adjusting mechanism regulates upper bracket 2 to rotate around lower carriage 6, and carries out locking in needs position.On two block plates of lower carriage 6, be provided with relative arc-shaped slot 11, arc-shaped slot 11 arranges taking dead axle 5 mounting points as the center of circle.
Angle adjusting mechanism 3 comprises angular adjustment handle 4, cam 9, recessedly takes turns 10, regulating shaft 8, adopts cam dislocation fastening to realize locking.Regulating shaft 8 is connected lower carriage by the hole on upper bracket with the arc-shaped slot 11 on lower carriage, and can move along arc-shaped slot.One end of regulating shaft 8 and recessedly take turns 10 and be rigidly connected, and be set with angular adjustment handle 4 in same one end, on angular adjustment handle 4, there is cam 9, cam 9 is positioned at recessed 10 inner sides of taking turns, and forms locking structure.Regulating shaft 8 other ends are stuck in outside arc-shaped slot by the spindle nose that is greater than arc-shaped slot 11.Referring to Fig. 2 A and Fig. 2 B, its locking embodiment is: locking structure is in releasing orientation under normal circumstances, in the time that needs switch to lockup state by releasing orientation, rotational angle adjusting handle 8, due to adjusting handle 8 with cam 9 for being rigidly connected, so adjusting handle 8 is with moving cam 9 to rotate, and recessed take turns 10 and regulating shaft 8 between for being rigidly connected, take turns 10 so recessed and remain static.Cam 9 rotates to cam 9 tops with recessed 10 tops of taking turns while being meshed, and cam 9 and recessed lateral separation of taking turns between 10 become large.Cam 9 pushes the inside drawdown deformation of lower carriage 6, forms larger contact friction force between lower carriage 6 and upper bracket 2.Friction force tightly fits together the steel plate of two supports, makes between main installed surface 1 and mounting seat 7 in relative static conditions.Now lockable mechanism is just in lockup state.When lockable mechanism is during in lockup state, the angle of whole frock can not be adjusted.In the time that needs switch to releasing orientation by lockup state, due to adjusting handle 4 with cam 9 for being rigidly connected, so adjusting handle 4 is with moving cam 9 to rotate, and recessed take turns 10 and regulating shaft 8 between for being rigidly connected, take turns 10 so recessed and remain static.Cam 9 rotates to cam 9 tops with recessed 10 bottoms of taking turns while being meshed, and cam 9 and recessed lateral separation of taking turns between 10 diminish.Cam 9 no longer pushes the inside drawdown deformation of lower carriage 6, and friction force between the two significantly reduces.Between main installed surface 1 and mounting seat 7, can relative motion regulate, now locking structure is just in releasing orientation.
Referring to Fig. 3, this figure is that the present invention has angle mark on the arc-shaped side of the arc-shaped slot 11 of lower carriage 6, angulation index plate 13, and on the spindle nose of regulating shaft 8, be provided with angle indicator 12, the least unit of angle-differentiated dish is 1 degree.In the time carrying out angular adjustment, be used in conjunction with by angle indicator 12 and angle-differentiated dish 13, realize the benchmark control of angle.
Angle adjusting mechanism 3 embodiments are: while carrying out angular adjustment, first rotational angle adjusting handle 4, makes cam and recessed locking system of taking turns composition in releasing orientation, then unclamps dead axle 5 simultaneously and adopts adjusting bolt.Rotate main installation panel 1 it is rotated around dead axle 5, angle indicator 12 is alignd with the angle index of required adjusting on angle-differentiated dish 13.Finally rotate again adjusting handle 4, make cam and recessed wheel in lockup state, tighten dead axle 5 simultaneously.Realize applicable the suspending of differing tilt angles of the present invention with this and carry out rigidity test.
Again referring to Fig. 1, mounting seat 7 of the present invention is connected with testboard bay 18 by 8 bolts, compared with traditional connected mode, can ensure that the installation mode of test fixture is higher, while avoiding dynamic stiffness test, resonate, can effectively improve dynamic performance testing accuracy.
Referring to Fig. 5 Fig. 6, this figure is the schematic diagram that suspends that the present invention is suitable for different installation sites.On installation panel 1, there is the mounting hole of 17 annular arrays, suspend and be generally 2 points, or 4 fixed forms at 3, as 4 in figure fixedly suspend 16 and 2 fixedly suspend 17, and by the combination in 17 holes on panel, substantially can ensure that suspending of different installation sites all can be arranged on installation panel 1.Can also coordinate X-over to carry out accommodation simultaneously.
