Specific embodiment
Below in conjunction with attached drawing, detailed description of the preferred embodiments, these explanations are only exemplary
, it is no intended to it limits the scope of the invention.
Specifically, the hydraulic pilot bearing device for installing and adjusting of the vertical expanding table top of vibration experiment, including bottom plate
1, the screw thread top 4 of screw thread support 2, locking ring 3 and convex shape, bottom plate 1 are former slab structure, with a thickness of 30mm, outer diameter 410mm, with
Vertical expanding table support construction is that uniformly distributed 8 M8 screws are connected and fixed on 390mm circumference by diameter.Screw thread support 2 is hollow circle
Column construction, outer diameter 400mm, wall thickness 22mm are connected and fixed with bottom plate 1 by 8 M6 screws on diameter 360mm circumference.Spiral shell
The inner wall of line support 2 sets standard female, and the bottom outer wall on convex shape screw thread top 4 is equipped with external screw thread, and effective length 55mm passes through
Internal and external threads, which cooperate, realizes the lifting of screw thread top entirety, passes through when operation on 4 outer wall of screw thread top one week on the outer wall of screw thread top
Uniformly distributed 8 adjustings screw holes, can the moderate pairs of screw of screw-in length, by applying the positive and negative torque of axial direction, Lai Shixian spiral shell to screw
The lift adjustment of line top edge axis direction, adjustable range range are 0 to 50mm.After the position on screw thread top 4 is adjusted, 8 are used
M6 screw is penetrated on locking ring 3 in uniformly distributed 8 through-holes, and is connect by screw thread with screw thread support, so that locking ring pressure 3 is connected to type
On the outside step on shape screw thread top, the locking on screw thread top 4 is realized.Locking ring 3 is the cyclic structure of section inverted L-shaped, outer diameter and spiral shell
