Simple inner hexagonal bolt automatic paint dripping sleeve

Abstract

The invention discloses a simple inner hexagonal bolt automatic paint dripping sleeve which comprises an inner hexagonal sleeve rod, a liquid storage bottle, a spring, felt, a paint dripping sheath and a liquid conveying pipe. The liquid storage bottle is combined on the inner hexagonal sleeve rod; the paint dripping sheath is slidably combined at the lower end of the inner hexagonal sleeve rod; the paint dripping sheath is filled with the felt; the spring is distributed between the liquid storage bottle and the paint dripping sheath; and the liquid conveying pipe communicates with the liquid storage bottle and the paint dripping sheath. After being continuously used, the simple inner hexagonal bolt automatic paint dripping sleeve is still good in paint dripping effect, uniform in paint dripping, wide in application range, large in ink storage amount, high in efficiency, simple in structure, low in production cost, high in bolt tightening strength and good in stability.

Description

technical field [0001] The invention relates to the technical field of engine assembly, in particular to a simple automatic paint spotting sleeve for inner hexagon bolts. technical background [0002] During the assembly process of the engine, the three-inspection system will be implemented. In order to ensure the torque of the bolts during the three-inspection system, it is required that the engine bolts need a simple and suitable automatic painting tool. Instead of using a paint spotting tool, manual scribing and spot painting with a paint pen will easily cause the torque of the bolt to be missed, the paint will be uneven, and it will take a long time, which may cause hidden dangers to the quality and safety of the engine. Although, there are similar automatic paint spotting tools at present, such as patent number: 201510161941.8, a bolt tightening torque wrench for automatic paint spotting, the present invention discloses a bolt tightening torque wrench for automatic pain...

AI Technical Summary

Problems solved by technology

However, the adoption of this technical solution will lead to the following technical problems: In this patent, because the front end of the spring is distributed with wadding, in actual use, because the height of the bolt head is constant, there will be problems when the wrench is applied to the corresponding bolt head at the beginning. The amount of spot paint ink is large, but after using it many times, because the depth of the wrench inserted into the bolt head is consistent, the squeezing force on the inner spring of the wrench is also the same, so the spring cannot continue to squeeze, and the cotton wool at the lower end If the ink cannot be supplied, it will lead to poor spot paint effect and blurred spot paint, and if the wrench sets the bolt socket deeper to prevent this problem, it will also create another problem, which is the socket of the bolt head. The depth cannot be controlled. If the amount of ink squeezed out is too much, it will easily flow into the engine, which will not only affect the appearance but also easily affect the performance of the engine. At the same time, this technical solution cannot store ink and needs to be filled frequently. Therefore, the use effect of this technical solution is not good.
