Description

Technical Field

[0001] The utility model relates to the field of bolt assembly tools, in particular to an automatic assembly tool for air duct bolts. Background Art

[0002] During the installation of air ducts, bolts are used to fix the angle steel flange and the pipe shaft wall. However, in actual projects, in order to ensure the use area of ​​the building, the air ducts are often arranged closely, which makes the space for tightening the bolts very narrow. It is impossible to tighten the bolts in this position using general tools or mechanical devices, resulting in excessive leakage in the pipeline system, affecting the construction and acceptance quality, and may affect the wear resistance and service life of the metal materials. There is a potential risk of air leakage. When installing various air ducts, automatic assembly tools are needed to install and disassemble the bolts.

[0003] However, most of the current automatic assembly tools for duct bolts have the following problems:

[0004] For example, a portable air duct bolt installation device with publication number CN202222655748.8, although the length of the equipment can be adjusted by a telescopic rod, the adjustment distance by the telescopic rod is limited. If the bolt to be removed is long, it is easy for the bolt to be unable to be fully removed or installed, affecting the stability of use and inconvenience in adjusting and using it according to the use situation; at the same time, the nut tightening assembly and the positioning seat used are in a fixed state, and the bolts are of different sizes. If the bolt to be removed and installed is larger or smaller, it is easy for it to be unable to engage and disassemble, affecting the use efficiency, and after long-term use, the groove of the internal engaging bolt is prone to wear. If it is not replaced in time, it is easy to slip, and the bolt cannot be removed and installed, and it is inconvenient to disassemble and replace the nut tightening assembly and the positioning seat used.

[0005] Therefore, we make improvements to this problem and propose an automatic assembly tool for air duct bolts. Utility Model Content
