Abstract

The invention discloses an electric wrench which comprises a driving disc, wherein a driving shaft and a group of driven shafts are connected onto the driving disc in a running fit manner; the driven shafts are arranged on the same circumference using the driving shaft as a circle center; a driving gear is connected onto the driving shaft; a nut sleeve is connected onto each driven shaft; driven teeth meshed with the driving gear are arranged on the outer side of each nut sleeve. The electric wrench has the advantages as follows: the electric wrench provided by the invention is simple in structure and simple and convenient to operate; a motor drives the driving shaft to drive the multiple driven nut sleeves, and clamp nuts arranged circumferentially can be fastened simultaneously, so that the working efficiency is improved and the purely mechanized operation is realized conveniently.

Description

technical field [0001] The invention relates to a universal mechanical fixture, in particular to an electric wrench capable of fastening a plurality of circumferentially distributed nuts at the same time. Background technique [0002] In mechanical engineering, fasteners with outer nuts are often distributed in a circular shape, and the number is three, four, five or more, such as: fastening nuts for automobile tires. The usual fastening operation method is manual operation with a torque measuring wrench or a fixed torque electric wrench operation. This mode of operation can only fasten one nut at a time, and repeated operations are performed many times, the work efficiency is low, and it is unfavorable for mechanized operation. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose an electric wrench. [0004] In order to achieve the above object, the present invention adopts the following techn...
