Horizontal Large Nut Installer

Abstract

The invention discloses a horizontal large nut installer. It includes: a rotator, in which the large nut is fixed and can freely rotate around the central axis of the large nut; and a buffer, under which the rotator is suspended. The rotator mainly consists of an upper supporting frame, a lower supporting frame and several bearings. The buffer is mainly composed of a mounting frame, a hook and an elastic component. The rotator of the present invention can make the large nut freely rotate vertically and stably in it, and the buffer can make the thread of the large nut evenly stressed when it is installed, and finally realize the unscrewing or screwing action of the large nut easily, and it is not easy The thread is strained, thus effectively solving the problem of increased friction and unilateral force of the large nut caused by the gravity of the nut when the large nut is installed horizontally.

Description

technical field [0001] The invention relates to a large nut installation auxiliary device, in particular to a horizontal large nut installer. Background technique [0002] In the process of installation and maintenance of industrial equipment, when installing nuts or screws, the most feared thing is that the surface of the thread will be strained, because the thread will produce a small amount of iron cutting after the thread is strained, and the iron cutting will grind more and more, just like a snowball In that way, the nut is screwed tighter and tighter, and cannot be screwed out or screwed in, which eventually leads to a "stuck" phenomenon. At this time, it will be very difficult to remove the nut (especially the large nut), and even the part will eventually be scrapped. [0003] Large nuts are much more difficult to install than small and medium-sized nuts. In addition to the fact that large nuts are relatively bulky, when the hardness of the thread surface is constant...

Problems solved by technology

[0002] In the process of installation and maintenance of industrial equipment, when installing nuts or screws, the most feared thing is that the surface of the thread will be strained, because the thread will produce a small amount of iron cutting after the thread is strained, and the iron cutting will grind more and more, just like a snowball In that way, the nut is screwed tighter and tighter, and cannot be screwed out or screwed in, and finally leads to "stuck" phenomenon

At this time, it will be very difficult to remove the nut (especially a large nut), and even the part will eventually be scrapped

[0003] Large nuts are much more difficult to install than small and medium-sized nuts. In addition to the fact that large nuts are relatively bulky, when the hardness of the thread surface is constant, the heavier the nut, the greater the friction when rotating, and the easier it is to damage the thread surface. finish, and eventually strain the threads; at the same time, high friction can make it very difficult for large nuts to be installed and rotated

In addition, the horizontal installation of large nuts is much more difficult than the vertical installation. The main reason is: due to the gravity factor, when the horizontal nut is installed, the force is mainly on the upper side, so the friction generated when the nut is rotated is greater. , more likely to strain the threaded surface
