Abstract

The invention relates to the technical field of wrenches, and discloses an electric wrench for an engraving machine tool rod. The electric wrench comprises a fixing plate, a strip-shaped groove is transversely formed in the upper side of the fixing plate, a bidirectional screw rod is transversely arranged in the strip-shaped groove, the left end of the bidirectional screw rod is rotationally connected with the left side of the strip-shaped groove through a rolling bearing, a motor is fixedly arranged on the right side wall of the strip-shaped groove, the output end of the motor is fixedly connected with the right end of the bidirectional screw rod through a coupler, two moving blocks are symmetrically arranged in the strip-shaped groove in a sliding mode, the side walls of the two moving blocks are in threaded connection with the two sides of the rod wall of the bidirectional screw rod through a first threaded hole and a second threaded hole respectively, and connecting rods are fixedly arranged on the upper sides of the two moving blocks. According to the electric wrench, the operation intensity of workers is reduced, and a first arc-shaped clamping plate and a second arc-shaped clamping plate can be guaranteed to stably clamp the tool rod, so that the dismounting and mounting efficiency of the tool rod is improved.

Description

technical field [0001] The invention relates to the technical field of wrenches, in particular to an electric wrench for an engraving machine tool bar. Background technique [0002] At present, two extended spanners are usually used for the disassembly and assembly of the ultrasonic tool bar, one is stuck on the horn and the other is stuck on the tool bar, and the tool bar is disassembled and assembled with two hands or two people at the same time. Because the horn is fixed on the equipment, when disassembling the tool bar, the wrench stuck on the horn is easy to twist the horn, and using two bulky extended wrenches at the same time is not conducive to operation, which increases the operating strength of the staff , and the clamping effect on the tool rod is not good, so it is easy to cause the screw not to be tightened or tightened too tightly. [0003] Among them, the patent number is CN206812683U, which discloses a tool bar wrench for ultrasonic engraving machine, includ...
