Multipurpose low torque electromechanical wrench device

Abstract

The invention discloses a multipurpose low torque electromechanical wrench device, and relates to the technical field of wrenches. The multipurpose low torque electromechanical wrench device comprisesa hand shank, a torquer and a shaping fastening device, wherein the torquer comprises a V-shaped connecting frame, a master control gear and a motor; the middle of the connecting frame is connected with the front end of the hand shank; the left side and the right side of the front part of the connecting frame are connected with arc positioning shells; the side edges of the positioning shells areconcaved inward to be matched with the edge of the master control gear; inserted connection holes are evenly formed in a guide groove; the interiors of through holes are in sliding connection with control locks matched with the inserted connection holes; the shaping fastening device comprises an outer shell and a sound wave generation device, and the outer shell is fixedly connected with the innerwall of a mounting hole; an annular elastic bag is fixedly sleeved with the outer shell and filled with shear thickening fluid, and the outer side of the elastic bag is fixedly connected with the interior of the outer shell; and the output end of the sound wave generation device is installed on the outer shell and is opposite to the elastic bag. The multipurpose low torque electromechanical wrench device has the beneficial effects that specification adjustment is quick, adaptability is high, operation is easy, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of wrenches. Background technique [0002] A wrench is a commonly used installation and removal tool that uses the principle of leverage to turn bolts, screws, nuts, and other hand tools that are threaded to hold the openings or casings of bolts or nuts. Generally, wrenches are divided into dead wrench and adjustable wrench. Adjustable wrench can adjust the opening within a certain range to adapt to the use of various specifications, but generally adopts a semi-enclosed method, and the connection is unstable, resulting in failure problems during torque transmission. When adjusting, it cannot be adjusted in place quickly at one time, which brings troubles to the operator, and repeated manual adjustments cause operational fatigue. When a general low-torque multi-purpose electromechanical wrench device is in use, it can be divided into two stages: fast rotation and high-torque force application, so it should b...
