Problems solved by technology
Due to the heavy valve body of the pressure regulator with a large nominal diameter, the current pressure regulator manufacturers basically need workers to use a crane to turn over the half-assembled valve body during the assembly process. This process is time-consuming.
In addition, due to the large main valve body, various assembly operations are completed on a flat workbench, without fixing and clamping the valve body, only by the friction between the valve body itself and the workbench. Prevents movement of the entire valve body during assembly, lack of reliable positioning

Embodiment 1
[0024] An assembly tool for a pressure regulator, the structure of which is as follows figure 1 , figure 2 As shown, it includes a base 1 and a bracket 2, wherein the bracket 2 adopts an I-shaped steel structure, which can reduce the weight of the whole mechanism and ensure the strength. The form of the upper bearing seat adopts a split type, including a lower cover 3 and an upper cover 4 , the lower cover 3 is welded on the top of the bracket 2 , and the upper cover 4 and the lower cover 3 are fixed by bolt groups 5 .
[0025] Two cylindrical roller bearings 14 are installed on the collar position of the main shaft 13, and the arrangement is face-to-face. The inner ring of the roller bearing 14 cooperates with the collar to realize axial fixation. Bearing 13 is installed in the bearing housing.
[0026] A handle 7 is installed on the side of the rotating member 6 for sliding and rotating the rotating member 6 manually.
[0027] The rotating part 6 realizes synchronous ro...

The invention relates to an assembly tooling for a pressure regulator. The assembly tooling comprises a base, a bracket vertically fixed to the base, a bearing pedestal fixedly installed on the top ofthe bracket, a main shaft of which one end is coupled to the interior of the bearing pedestal, a rotating part slidably arranged in the middle of the main shaft in a sleeved manner, and a flange arranged at the other end of the main shaft in the sleeved manner and used for fixing a valve body of the pressure regulator; the rotating part and the flange are synchronously rotated with the main shaftthrough a No.1 key and a No.2 key separately; and the rotating part and the bearing pedestal are provided with fixing components which are matched with each other and used for preventing the main shaft from rotating. Compared with the prior art, the assembly tooling has the advantages that the valve body needs to be clamped in one time during assembly, and does not need to be turned over througha crown block or other devices in the process, so that the assembly efficiency is improved; the valve body is installed on the tooling by bolts and nuts, so that the valve body is reliably located inthe assembly process, and the assembly accuracy can be improved; and the safety of the assembly operation is improved.
Description
technical field [0001] The invention relates to the field of assembly technology, in particular to an assembly tool for a voltage regulator. Background technique [0002] The straight rod type pressure regulator includes a valve body and a cavity. When assembling, it is necessary to install the valve port and the end cover in one direction (some pressure regulators with built-in closing structure are also installed on this side), then turn it over, and install it in the other direction. The cavity, main shaft, film and spring are installed on the side. Due to the heavy valve body of the pressure regulator with a large nominal diameter, the current pressure regulator manufacturers basically need workers to use a crane to turn over the half-assembled valve body during the assembly process. This process is time-consuming. In addition, due to the large main valve body, various assembly operations are completed on a flat workbench, without fixing and clamping the valve body, onl...
