Opposite-knocking type reaction arm mechanism

Abstract

The invention relates to the technical field of fastening equipment, and particularly discloses an opposite-knocking type reaction arm mechanism. The opposite-knocking type reaction arm mechanism includes a cross beam, a force arm rod mounted on the cross beam and capable of horizontally moving in the length direction of the cross beam and a tool clamping device fixedly connected to one end of thecross beam and used for fixing an electric power tool. A stretched elastic member is connected between the force arm rod and the cross beam, and the bottom end of the force arm rod is connected witha fixing sleeve for being connected with a nut or a bolt in a sleeving mode. When the electric power tool is clamped on the tool clamping device, the fixing sleeve is opposite to the power output endof the electric power tool. The opposite-knocking type reaction arm mechanism can directly offset the reaction force when staff performs fastening operation, and reduces corresponding torque engineering, thereby facilitating the improvement of work efficiency and reducing labor intensity.

Description

technical field [0001] The invention relates to the technical field of fastening equipment, in particular to a counter-knock type reaction arm mechanism. Background technique [0002] Bolts and nuts are used for fastening connections between parts. When employees perform assembly and fastening operations, they first use a wind wrench for pre-tightening, and then need to use a wrench to manually tighten them to prevent the bolts and nuts from being tightened. Co-rotation occurs due to the existence of reaction force. During this process, because the wrench is clamped manually, employees cannot ensure that it is completely locked without co-rotation. Therefore, a torque test is still required after the tightening operation to ensure that the workpiece It is required to lock in place, but co-rotation must also be prevented in the torque test project, and two people are required to cooperate, resulting in long time-consuming, low work efficiency, and high cost. Moreover, when th...

[0002] Bolts and nuts are used for fastening connections between parts. When employees perform assembly and fastening operations, they first use a wind wrench for pre-tightening, and then need to use a wrench to manually tighten them to prevent the bolts and nuts from being tightened. Co-rotation occurs due to the existence of reaction force. During this process, because the wrench is clamped manually, employees cannot ensure that it is completely locked without co-rotation. Therefore, a torque test is still required after the tightening operation to ensure that the workpiece It is required to lock in place, but co-rotation must also be prevented in the torque test project, and two people are required to cooperate, resulting in long time-consuming, low work efficiency, and high cost. Moreover, when the operator uses the wind wrench, the left and right hands are subject to vibration. At the same time, in order to ensure the torque of the workpiece, employees in torque positions have to twist more turns. In the case of large torque, the labor intensity is relatively high.
