Detailed Description
The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:
referring to fig. 1 and 2, fig. 1 is a schematic view illustrating an operating state of an embodiment of the present invention, and fig. 2 is a side view of fig. 1. The hydro-pneumatic spring hanging mechanism of the invention is arranged on a workbench 4 and comprises: the mounting plate 1 is connected with the workbench 4; two hitch plates 2 are installed respectively install the both ends of mounting panel 1, two distance between hitch plate 2 is greater than the width of the joint bearing installation interface of the hydro-pneumatic spring 5 that awaits measuring, every hitch plate 2 includes connecting portion 21, hitching part 22 and guide part 23, connecting portion 21, hitching part 22 and guide part 23 are preferred integrative, the top of connecting portion 21 with mounting panel 1 is connected, hitching part 22 one end with connecting portion 21 connects, the one end of guide part 23 with the other end of hitching part 22 is connected, the other end of guide part 23 be higher than with the one end that hitching part 22 is connected, hitching part 22 with round pin axle 6 adaptation. The mounting plate 1 and the two hanging plates 2 jointly form a support 10; and the baffle 3 is arranged between the connecting part 21 and the pin shaft 6 and comprises a hanging matching part 31 and a limiting matching part 32, the hanging matching part 31 is matched with the bottom end of the connecting part 21, the limiting matching part 32 is matched with the pin shaft 6, and the limiting matching part 32 is matched with the hanging part 22 to limit the freedom degree of the pin shaft 6 along the vertical direction.
Referring to fig. 3 to 5, fig. 3 is a schematic structural view of an embodiment of the present invention, fig. 4 is a schematic structural view of a support according to an embodiment of the present invention, and fig. 5 is a left side view of fig. 4. The hanging plate 2 further comprises a limiting part 24, and the limiting part 24 is arranged at one side of the bottom end of the connecting part 21 opposite to the hanging part 22. The limiting part 24 is preferably a limiting boss, and the top end of the baffle 3 is provided with a groove 33 matched with the limiting boss. One end of the limiting boss, which is positioned outside the connecting part 21, can be provided with a chamfer of 3.5x45 degrees, so that the guide during plugging is facilitated.
Referring to fig. 6 and 7, fig. 6 is a schematic view illustrating a stopper structure according to an embodiment of the invention, and fig. 7 is a left side view of fig. 6. And the top ends of the two sides of the baffle 3 are respectively provided with a chamfer angle of 45 degrees.
