Detailed Description
The following detailed description of specific embodiments of the invention, taken in conjunction with the accompanying drawings, is intended to be illustrative only and is not intended to limit the scope of the invention.
Particularly, the hydraulic pressure direction bearing installation adjusting device of the vertical extension mesa of vibration test system holds in the palm 2, the locking ring 3 and the thread top 4 of type of dogbone including bottom plate 1, screw, and bottom plate 1 is former plate shape structure, and thickness is 30mm, and external diameter 410mm is fixed through the diameter 8M 8 screwed connection of equipartition on being 390mm circumference with vertical extension platform bearing structure. The thread support 2 is a hollow cylindrical structure, has an outer diameter of 400mm and a wall thickness of 22mm, and is fixedly connected with the bottom plate 1 through 8M 6 screws on the circumference with the diameter of 360 mm. The screw thread holds in the palm 2 inner wall and establishes standard internal thread, be equipped with the external screw thread on the bottom outer wall of type arch thread top 4, effective length 55mm, realize the holistic lift of thread top through the internal and external screw thread is mutually supported, through 8 regulation screw holes of a week equipartition on the thread top outer wall on the thread top 4 outer walls during operation, can screw into the moderate twin screw of length, through applying axial positive and negative moment to the screw, realize the lifting control of thread top along the axis direction, the adjusting distance scope is 0 to 50 mm. After the position of the thread top 4 is adjusted, 8M 6 screws are used for penetrating 8 through holes uniformly distributed on the locking ring 3 and are connected with the thread support through threads, so that the locking ring is pressed on the step on the outer side of the convex thread top 3 to realize the locking of the thread top 4. The locking ring 3 is the cyclic annular structure of the shape of the cross-section falling L, and the external diameter is the same with the external diameter of screw thread support 2, and the internal diameter is supporting with the thread top of type shape, and thickness is 25mm, compresses tightly fixed back, holds in the palm 3 up end with the screw thread and apart from being greater than 2mm, ensures to lock thread top 4. The top surface of the convex thread top is a mounting surface 5 for a large-bearing static pressure oil pad bearing, and the area is designed according to the area of a base of the large-bearing.
As shown in fig. 1, the present invention is simple in composition, comprising only four components: base 1, thread support 2, locking ring 3 and thread top 4. The thread support 2 is fixedly connected with the base 1 in a threaded manner, and the thread top 4 and the thread support 2 are designed to be M317.5 multiplied by 1.25mm and are screwed together. Fig. 2 is a schematic diagram of the general large-load static pressure oil pad bearing profile, which is fixedly connected with a thread top in a threaded manner, and can be screwed into a screw rod through a small threaded hole in the outer edge of the thread top to serve as a handle, and the thread top is manually rotated to screw in and screw out the bearing. In the actual debugging process, the steps are as follows:
