Screwing tool for automatically tagging inner hexagonal bolt

Abstract

The invention discloses a screwing tool for automatically tagging an inner hexagonal bolt. The screwing tool comprises a base body, wherein a first connecting part adaptive to a wrench is arranged at the back end of the base body, the front end of the base body is provided with a second connecting part adaptive to the inner hexagonal bolt, and the axes of the first connecting part and the second connecting part are coincided with that of the base body; the second connecting body comprises an outer hexagonal screwing head detachably mounted on the base body; and the screwing tool also comprises a tagging structure which is matched with the outer hexagonal screwing head for working and tags the inner hexagonal bolt. The screwing tool is reasonable in structure, convenient, practical, simple in operation, capable of automatically tagging a tag, meaning that the inner hexagonal bolt has been screwed, on the inner hexagonal bolt, the missing of torque tightening work of the bolt is prevented, the quality of the machine and device is ensured, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of assembly, more specifically, it relates to a tool for automatically marking hexagon socket head bolts for tightening. Background technique [0002] There are many parts in the engine. Due to special assembly reasons and structural requirements, the bolts fastening these parts need to be designed as hexagon socket bolts. When assembling and tightening these bolts, in order to confirm whether the hexagon socket bolts have been tightened to the torque, the traditional method cannot be carried out. At the same time as the tightening torque is tightened, it is necessary to manually independently use a paint pen to confirm the paint one by one. This method wastes most of the At the same time, when the production volume is large, the personnel are fatigued and the spirit is not concentrated, it is very easy for the bolt to miss the torque accident. Contents of the invention [0003] The object of the present invention ...
