Problems solved by technology

Tightening frock in the prior art (as figure 1 As shown), since the rubber ring is gradually squeezed by force during the manual tightening process, it is easy to produce elastic deformation and stretching and extension, and then the ring is cut. After the ring is cut, the sealing ring loses its sealing effect in the washing process, resulting in air machine water failure

Abstract

The invention relates to the technical field of engine assembly tools, in particular to a plug tightening tool. The embodiment of the invention provides a screw plug tightening tool which is used for screwing a screw plug into a threaded hole of a to-be-connected piece. The sleeve is used for being matched with a plug and driving the plug to rotate, and the fixing sleeve is used for containing a sealing ring of the plug. Wherein the sleeve is connected with the fixing sleeve, when the screw plug is tightened, the sleeve is arranged on the outer side wall of the screw plug in a sleeving mode, the fixing sleeve is arranged on the outer side of a sealing ring of the screw plug in a sleeving mode, and when the fixing sleeve rotates in place, the bottom end of the fixing sleeve abuts against a part to be connected. According to the screw plug tightening tool, due to the fact that the fixing sleeve special for containing the sealing ring is arranged, in the screw plug tightening process, when the sealing ring is tightened in place, the bottom end of the fixing sleeve abuts against the to-be-connected piece, the problem that in the manual tightening process of an existing product, the sealing rubber ring of the screw plug is extruded and cut can be effectively solved, and the production efficiency is improved. And the problem of water inflow of the air compressor is avoided.

Description

technical field [0001] The present application relates to the technical field of engine assembly tools, in particular to a plug tightening tool. Background technique [0002] The air compressor is an important part of the engine and also plays a vital role in the braking of the car. The engine high-pressure spray washing process is an important process in the current engine manufacturing process. The connection between the engine air compressor and the vehicle is a metal threaded hole. The industry uses plastic screw plugs and sealing rubber rings for water washing protection. It is sealed by tightening to ensure that water ingress due to the washing process is avoided, which will lead to internal corrosion of the air compressor, and even cause hidden dangers to customer driving safety caused by performance degradation. Tightening frock in the prior art (as figure 1 As shown), since the rubber ring is gradually squeezed by force during the manual tightening process, it is ...
