Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valve body processing, in particular to a valve body drilling processing and fixing device. Background Art
[0002] During the production process of the valve body, it is necessary to drill holes in the connecting flange at its end. After the connecting flange is drilled, it can be connected to other equipment by bolts. The current technology does not have special fixing tooling when drilling holes in the connecting flange of the valve body, so its processing efficiency is low and its production quality is unstable. Utility Model Content
[0003] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a valve body drilling and fixing device.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a valve body drilling and fixing device, comprising a workbench, an assembly column is fixedly installed on the upper end of the workbench, a three-way joint is placed on the outside of the assembly column, a hydraulic tensioning device is arranged in the assembly column, the hydraulic tensioning device is used to tension and fix the three-way joint from the inside, and the left side and the upper part of the three-way joint are both provided with drilling mechanisms.
[0005] Furthermore, the hydraulic tensioning device includes a hollow groove, which is arranged inside the assembly column. The outer side of the hollow groove is connected to a plurality of groups of mounting grooves, which are also arranged inside the assembly column. The mounting pipe is sealed and installed in the mounting groove.
[0006] Furthermore, a sealing gasket is installed in the installation tube for sliding left and right, a connecting column is fixedly installed on the outside of the sealing gasket, a mounting block is fixedly installed on the outside of the connecting column, and a flexible pad is fixedly installed on the outside of the mounting block.
[0007] Further, the flexible pad is in contact with the inner wall of the three-way joint.
[0008] Furthermore, the interior of the hollow groove is filled with hydraulic oil, and the exterior of the hollow groove is connected to a hydraulic device via an oil pipe.
[0009] The beneficial effect of the utility model is as follows: by inserting the three-way joint into the assembly column, and then starting the externally arranged hydraulic device, the hydraulic oil squeezes each group of sealing gasket blocks toward the outside, and then the sealing gasket blocks drive the connecting column and the mounting block to move outward, and the flexible pad contacts the inner wall of the three-way joint through the flexible pad. The flexible pad can be adapted to the inner walls of different three-way joints, the three-way joint is fixed, and then the external drilling mechanism is started to drill holes in the valve body connecting flange.
