Problems solved by technology

However, in order to ensure the uniformity of the graphite coating during the spraying process, it is generally necessary to keep the piston in a rotating state. At this time, the cork is prone to fall off, causing graphite to splash into the pin hole, increasing the rework rate and reducing production. efficiency

Embodiment Construction

[0020] Such as figure 1 , figure 2 As shown, the present invention provides a pin hole protection device for piston inkjet, comprising a handle 10 and an insertion part 20, the insertion part 20 cooperates with the piston pin hole, and the insertion part 20 is away from the handle One end of 10 is fixed with magnet 30, wherein magnet 30 can adopt NdFeB permanent magnet, because the piston material mostly is aluminum alloy structure, does not have ferromagnetism, thus does not interfere with the use of magnet 30 mutually, this technical scheme passes magnet 30 Designed so that when the guard is inserted into the pin hole of the piston, it can attract each other with the magnets on the guard set in the pin hole at the corresponding position, which improves its fixing effect during the rotation of the piston, thereby preventing it from moving from the pin The hole falls off, and the beneficial effect is remarkable.

Abstract

The invention relates to a pin hole protection device used during the graphite spraying period of a piston, and belongs to the technical field of engine manufacturing. The pin hole protection device comprises a handle part and an insertion part; the insertion part is matched with a pin hole of the piston, and a magnet is fixed to the end, away from the handle part, of the insertion part. According to the technical scheme, through the magnet, when the protection device is inserted into the pin hole of the piston, the protection device and the magnet on the protection device in the pin hole at the corresponding position can attract each other, the fixing effect of the protection device is improved in the rotation process of the piston, and therefore the protection device is prevented from falling off from the pin hole, and the beneficial effect is obvious.

Description

technical field [0001] The invention relates to a pin hole protection device used for piston inkjet, and belongs to the technical field of engine manufacturing. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. Its applications basically cover various fields related to mechanical equipment. Among them, the engine piston is an important component of the engine. The quality of the engine will directly affect the service life of the engine. In order to reduce the friction loss during the use of the piston, it is usually necessary to spray graphite on the surface of the piston to improve its lubricating performance, and this operation needs to cover and protect the pin hole on the side of the piston to avoid splashing into the pin hole during the graphite spraying process. Existing covering protection operation generally ado...
