Abstract

An embodiment of the invention discloses a nut tightening machine comprising a machine body, a power system and a clamping mechanism. The power system and the clamping mechanism are arranged on the machine body, and the clamping mechanism is used for clamping an output shaft matched with a nut to be tightened. The power system comprises a shell arranged on the machine body, a driving head rotatably arranged on the shell, a sleeve matched with the to-be-tightened nut, and a first driving unit arranged on the shell and used for driving the driving head to rotate. By the nut tightening machine, the nut can be tightened without being knocked, so that the problem that the appearance of the round nut is damaged during assembly is avoided completely by the assembly form. The output shaft does not need to be fixed manually, labor intensity of workers is lowered substantially, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tightening machines, more specifically, to a nut tightening machine. Background technique [0002] In various gearboxes, round nuts are widely used, such as figure 1 As shown, the round nut 01 is threadedly matched with the output shaft 02, and is used to abut against the inner ring of the bearing. As far as the tightening of round nuts is concerned, there are currently two main methods: one is to use a hook wrench 03 to tighten, such as figure 2 as shown; the second is to use the tooling 04 to directly or indirectly tap the notch on the outer circle of the round nut 01 to tighten it, such as image 3 shown. [0003] When tightening the round nut, the worker needs to fix the output shaft. For the first method, the operator can control the hook wrench to turn the round nut with one hand, and the other hand to hold the output shaft tightly to prevent the output shaft from rotating. . For the second me...
