Abstract

The present invention relates to a screw tightening device having a small-sized clutch, reduced in size and weight, and easily operable. A clutch (5) is directly connected to the output side of a DC motor (3), and as a result, the output of the DC motor (3) is less than the output of conventionally used motors. This reduces the size of the DC motor (3) and the clutch (5). Accordingly, the size and weight of a device body (1) are less than those of conventional products.

Description

technical field [0001] The present invention relates to a torque sensor capable of accurately and easily measuring a screw fastening device using an electric motor as a driving source and the fastening force on the driving side. Background technique [0002] As conventional screw fastening devices, there are angle type, pistol type, etc. Among them, there is known a screw fastening device having a structure in which a speed reducer is connected to the output side of the motor drive part, and a clutch is connected to the output side of the speed reducer. connected, and a socket tool is provided on the output side of the clutch (for example, refer to Patent Document 1). After tightening the screws, use a torque wrench to achieve the required tightening torque. [0003] As a mechanism for measuring the tightening axial force of a screw (bolt) to a fastened object, a strain gauge is installed between the screw and the fastened object on a bridge, etc. , There are built-in torq...
