The invention provides a large nut auxiliary installation mechanism, which is characterized in that the mechanism includes a support block, a support hydraulic cylinder rod, a support hydraulic cylinder piston, a support hydraulic cylinder body, a threaded screw, a large nut hook, a lead screw hook and Push the nut, the supporting hydraulic cylinder body is sleeved on the threaded screw, one end of the supporting hydraulic cylinder rod extends into the supporting hydraulic cylinder body and supports the hydraulic cylinder body to form a movable hydraulic cylinder structure, and the supporting hydraulic cylinder rod extends out of the supporting hydraulic cylinder body One end is provided with a support block, and one end of the support hydraulic cylinder rod protruding into the support hydraulic cylinder body is connected with the support hydraulic cylinder piston in the support hydraulic cylinder body; the push nut is installed on the non-screw-in end of the threaded screw, and is close to the support hydraulic cylinder body. Because the present invention has a small threaded hole or a tapered hole on the shaft for installing the nut, it is easier to center the large nut during installation; Supported by hydraulic cylinder, the operation is simple and convenient.
Description
technical field [0001] The invention relates to a nut installation mechanism, in particular to the installation of large nuts with large volume and difficult centering. Background technique [0002] During the installation process of the blades of large turbines and compressors, it is often necessary to use large nuts for reinforcement and positioning. During the installation process of such large nuts, due to their large size, alignment is often very difficult, which will greatly weaken the factory. Productivity. Contents of the invention [0003] Purpose of the invention: The present invention provides an auxiliary installation mechanism for large nuts, the purpose of which is to solve the problems of difficult centering and screwing in of the above-mentioned large nuts during the installation process. [0004] Technical solution: the present invention is achieved through the following technical solutions: [0005] A large nut auxiliary installation mechanism is charac...
