Problems solved by technology

This brings a lot of workload to the staff. Before the bolts are pre-tightened, the nuts need to be selected to the bottom of the bolts close to the flange surface. Previously, this work was done manually by the staff. There are many nuts to install. The time is also long, very inconvenient

Abstract

The invention relates to an electric nut preassembling tool and a using method thereof, and belongs to the technical field of handheld electric tools. According to the main technical scheme, the toolcomprises a tool shell, a driven bearing, a nut rotating sleeve, a driven gear, a driving gear, a driving gear shaft, a supporting shell sleeve, a driving bearing, a tool top cover, an electric wrenchand a wrench locking cover. The nut rotating sleeve is installed on the tool shell, and the driven bearing and the driven gear are fixed to the unthreaded shaft part of the nut rotating sleeve through a plurality of jackscrews. The driving gear shaft is mounted in a positioning hole of the tool shell, the driving gear shaft is supported by the driving bearing, the driving gear is mounted on the driving gear shaft through a positioning pin, and the driving gear and the driven gear are meshed and rotate synchronously. The biggest advantage of the tool lie in that a portable electric driving mode is adopted, the working time is saved, the workload of workers is reduced, the working efficiency is greatly improved, the labor cost is saved, the structure is simple and light, and materials are firm and durable.

Description

technical field [0001] The invention relates to a mechanical nut rotating tool, which belongs to the technical field of hand-held electric tools, and in particular relates to an electric nut pre-installation tool and a use method thereof. Background technique [0002] A type of product in the field of mechanical tools. In the installation and base fixing of large-scale equipment, bolts are mostly used to connect and pre-tighten. The number of bolts required for flange installation is very large, and the size of the bolts is often very long. This brings a lot of workload to the staff. Before the bolts are pre-tightened, the nuts need to be selected to the bottom of the bolts close to the flange surface. Previously, this work was done manually by the staff. There are many nuts to install. The time is also long, very inconvenient. Contents of the invention [0003] Aiming at the above-mentioned technical problems, the present invention provides a portable hand-held electric...
