Description

Vertical variable angle installation adjustment seat device

technical field

The utility model mainly relates to the technical field, in particular to a vertical variable-angle installation adjustment seat device, especially for devices that require vertical installation and angle adjustment.

Background technique

For devices that need to be installed vertically, such as large flapper valves, the valve body needs to be installed vertically to protect the valve core from damage. The verticality of the valve body is often ensured by adding or subtracting gaskets to adjust the verticality or improving the machining accuracy of the docking platform. Even if the verticality of this installation method meets the requirements temporarily, it is still difficult to guarantee the verticality of the deformation of the device platform as time goes on. And some special devices require the platform to be able to adjust the angle freely to achieve the purpose of collimating the device. For example, the EAST-NBI ion source of the Institute of Plasma, Chinese Academy of Sciences requires a 4.33-degree installation platform. It is difficult to meet the requirements in the actual installation process to ensure the accuracy of the angle only by the machining accuracy. This just needs novel vertically adjustable angle to install the adjustable seat platform.

Utility model content

In order to overcome the difficulty of ensuring the verticality of the device platform and the need for angle adjustment, the utility model provides a vertical variable angle installation adjustment seat device, the verticality and angle can be adjusted freely, and the installation space is small, the structure is simple, and the installation method is simple. Very convenient and fast.

The utility model is achieved through the following technical solutions:

The vertical variable angle installation adjustment seat device includes an installation platform and a female base, and is characterized in that: the installation platform is fixed on the female base through three joint bearing devices and a worm screw elevator; the joint bearing device It includes a support, a joint bearing rod, the joint bearing rod and the support are threaded and fixed by a compression nut, and the top of the joint bearing rod is provided with a bearing inner ring with an outer spherical surface and a bearing outer ring with an inner spherical surface composed of sliding bearings.

The vertical variable angle installation adjustment seat device is characterized in that: the worm screw elevator includes a base and a lifting rod.

The vertical variable angle installation adjustment seat device is characterized in that: the supports of the three joint bearing devices are fixed side by side on the female base at equal intervals, and the sliding bearings of the joint bearing devices are fixed on the installation platform.

The vertical variable angle installation adjustment seat device is characterized in that: the base of the worm lifter is fixed on the female seat, and one end of the lifting rod of the worm lifter is fixed on the installation platform.

The joint bearing device mainly includes a bearing inner ring with an outer spherical surface and a bearing outer ring with an inner spherical surface. A sliding bearing with a special structure can withstand a large load. Joint bearing devices are generally used for low-speed swing motion (that is, angular motion). Since the sliding surface is spherical, it can also perform tilt motion within a certain angle range (that is, the maximum swing angle of self-aligning motion is about 30 degrees). When the misalignment between the supporting shaft and the shaft housing hole is large, it can still work normally. The worm lift mainly plays the role of fixing the platform after the device is adjusted. The joint bearing rod and the support are connected by thread, and after the position is adjusted, it is compressed and fixed by the compression nut. The verticality and angle of the platform are ensured by adjusting the length and angle of the joint bearing rods of the three joint bearing devices. After meeting the requirements, the bearing rods are fixed by pressing the nuts, and the whole platform device is fixed by the worm lifter.

The beneficial effects of the utility model:

The utility model can meet the needs of vertical installation and the installation angle ranges from 0 to 30 degrees. The utility model adopts a joint bearing device and a turbine worm lifter, can bear a relatively large load, and has a simple structure and is easy to install.
