Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 3, the present invention will be further described:
As shown in Figure 1, a kind of threst stand fast replacing device, comprises quick change dolly 2, adjustable support leg 3, centralising device 5, dynamometer machine 6, hold down gag 7 and positioning plate 8.Wherein, dynamometer machine 6, hold down gag 7 and positioning plate 8 are fixed on mounting base 1, engine 4 is fixed on quick change dolly 2 by adjustable support leg 3, and engine 4 carries out centering by centralising device 5 and quick change dolly 2, and quick change dolly 2 carries out centering by positioning plate 8 and dynamometer machine 6.
Centralising device 5 is for the position centering between quick change dolly 2 and engine 4, and quick change dolly 2 comprises position adjustment and the fixture of engine, and has damping capaicty, reduces the vibrations of engine in process of the test, the accuracy of lifting test data.Meanwhile, also as the mounting bracket of associated pipe, cable.Positioning plate 8 is for ensureing the centering between quick change dolly 2 and dynamometer machine 6, and the reliable of quick change dolly 2 is fixed, prevent the position of quick change dolly 2 in process of the test from offseting, and by the positioning and clamping mechanism of design, the interchangeability of multiple quick change dolly can be ensured.
As shown in Figure 2, positioning plate 8 comprises longitudinal register block 81, horizontal positioning device 83 and plane positioning block 83.Positioning plate 8 two ends are respectively equipped with thick gathering sill 11 and hold down gag 7.
As shown in Figure 3, quick change dolly 2 comprises longitudinal register block 21, located lateral groove 22, plane positioning block 23, longitudinal locking device 24, thick guider 25 and crossbeam 26.Engine 4 is fixed on quick change dolly 2 by adjustable support leg 3.Crossbeam 26 realizes vertically moving by the longitudinal U-type groove on quick change dolly 2; Adjustable support leg 3 to be arranged on crossbeam 26 and to realize transverse shifting by the horizontal U-type groove on crossbeam 26; Adjustable support leg 3 realizes the movement of engine 4 vertical direction for Collapsible structure.
The operation principle that quick change dolly 2 and engine 4 carry out centering is as follows:
Engine 4 is being placed into after on quick change dolly 2, and crossbeam 26 can move along the longitudinal U-type groove on quick change dolly 2, for adjusting the lengthwise position of engine 4 on quick change dolly 2.Adjustable support leg 3 can move along the horizontal U-type groove on crossbeam 26, for readjusting the distribution the lateral attitude of motivation 4 on quick change dolly 2.Screw rod on adjustable support leg 3 can adjust the horizontal level of engine 4, while the above position of adjustment, centralising device 5 is used constantly to measure the benchmark of engine 4, finally complete the precise alignment of engine 4 and quick change dolly 2, re-use the locking nut on adjustable support leg 3, engine 4 and adjustable support leg 3 are fixed.Now, quick change dolly 2 is in centering and fastening state with engine 4.
The operation principle that quick change dolly 2 and dynamometer machine 6 carry out centering is as follows:
Be pushed in the process of positioning plate 8 at quick change dolly 2, by coordinating of thick guider 25 and thick gathering sill 11, quick change dolly 2 can be made to enter in the scope of horizontal positioning device 83 along relatively-stationary route, continue forward, direct located lateral groove 22 coordinates completely with horizontal positioning device 83, just completes the located lateral of quick change dolly 2.Positioning plate longitudinal register block 81, quick change dolly longitudinal register block 21 coordinate with longitudinal locking device 24, can complete the longitudinal register of quick change dolly 2, while completing above location, the plane positioning block 84 of positioning plate also completes the location of quick change dolly 2 in horizontal plane with coordinating of quick change dolly plane positioning block 23.Now, quick change dolly 2 and positioning plate 8 achieve locates completely, and positioning plate 8 and the position of dynamometer machine 6 are changeless, previous step adjustable support leg 3 has been located completely in quick change dolly 2 in addition, then show that engine 4 is centerings with the relative position of dynamometer machine 6.Again by longitudinal locking device 24 with hold down gag 7 by specifying torque locking, just complete whole centering and work.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious realization of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all in protection scope of the present invention without to improve.
