Abstract
An electromagnetic socket wrench belongs to mechanical tools; a pull rod is arranged on the outer part of the sleeve shell, a polygonal inner sleeve and an annular stator coil magnetic driver are coaxially and fixedly arranged on the inner side part of the sleeve shell from top to bottom in sequence, a permanent magnet is fixedly arranged on the upper end surface of a polygonal nut of the screw, and the permanent magnet consists of a plurality of N poles and S poles which are uniformly distributed along the circumferential direction at intervals; the wrench converts electric energy into mechanical energy by utilizing the principle of the electromagnetic induction law, completes the screwing of the screw on the screw hole, and has the characteristics of scientific, reasonable and simple structure, labor and force saving operation, high working efficiency and good consistency of screw tightening force.
Description
Technical Field
The invention belongs to mechanical tools, and mainly relates to a screw electromagnetic power mounting tool.
Background
In the assembly field of various single or a small amount of mechanical equipment, when a screw needs to be screwed into a threaded hole of a part, currently, a mechanical dead wrench with fixed wrench opening size or an adjustable wrench or a sleeve type wrench with adjustable wrench opening size is mainly used by twisting with a single hand or two hands, and when the wrench is used in operation, the wrench has the problems of low operation efficiency, high operation labor intensity, inconsistent screw tightening force, low assembly precision and the like.
Disclosure of Invention
The invention aims to solve the problems of mechanical solid wrenches, movable wrenches or socket wrenches in a single or small number of mechanical assembly sites, and develops an electromagnetic socket wrench to achieve the purposes of high screw mounting and screwing operation efficiency, reduced operation labor intensity and good screw assembling and screwing force consistency.
The purpose of the invention is realized as follows: a trigger bar is arranged on the outer part of the sleeve shell, and a polygonal inner sleeve and an annular stator coil magnetic driver are fixedly arranged on the inner side part of the sleeve shell from top to bottom coaxially and sequentially; and a permanent magnet is fixedly arranged on the upper end surface of the polygonal nut of the screw and consists of a plurality of N poles and S poles which are uniformly distributed along the circumferential direction at intervals, so that the electromagnetic socket wrench is formed.
The invention utilizes the principle of electromagnetic induction law, and the magnetic force driver of the annular stator coil is matched with the permanent magnet arranged on the screw and the nut to convert the electric energy into the mechanical energy for driving the screw to rotate so as to complete the installation of the screw.

Description of part numbers in the figures:
1. sleeve casing, 2, pull rod, 3, polygonal inner sleeve, 4, annular stator coil magnetic drive, 5, screw, 6, permanent magnet, 7, polygonal nut.
Detailed Description
The following detailed description of the inventive embodiments is provided in connection with the accompanying drawings. An electromagnetic socket wrench, a pull rod 2 is arranged on the outer part of a socket shell 1, a polygonal inner socket 3 and an annular stator coil magnetic driver 4 are fixedly arranged and arranged on the inner side part of the socket shell 1 from top to bottom coaxially in sequence; the permanent magnet 6 is fixedly arranged on the upper end face of a polygonal nut 7 of the screw 5, and the permanent magnet 6 is composed of a plurality of N poles and S poles which are uniformly distributed at intervals along the circumferential direction.
During the operation use, at first insert the polygon inner skleeve 3 downthehole location of polygon inner skleeve in sleeve casing 1 with the polygon nut 7 of the screw 5 of treating the installation, it is rotatory on spanner 2 to hold both hands, make 5 tip screw threads of screw detain the screw in the threaded hole centering location, afterwards, utilize sleeve casing 1 to drive polygon inner skleeve 3 break away from the suit cooperation with polygon nut 7, at this moment, the switch on power supplies power transmission for annular stator coil magnetic force driver 4, the magnetic force of annular stator coil magnetic force driver 4 makes the screw 5 rotatory entering threaded hole under the cooperation of permanent magnet 6, when torsion reaches the extreme value of annular stator coil magnetic force driver 4, accomplish the cooperation installation of screwing of screw 5.
