Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 4, a main engine lubricator removal tool in this embodiment includes an upper hoop 1 and a lower hoop 2, and the upper hoop 1 and the lower hoop 2 are connected by two left and right The bolt 3 is connected with the lock nut 4, the inner side of the upper hoop 1 and the lower hoop 2 is provided with an arc-shaped bayonet 6, and the front side of the arc-shaped bayonet 6 is provided with an arc-shaped shoulder 7, and the upper The middle part of the hoop 1 and the lower hoop 2 is provided with a supporting head screw 5, and the supporting head screw 5 on the upper hoop 1 and the supporting head screw 5 on the lower hoop 2 are located on the same vertical line;

The thickness of the arc-shaped shoulder 7 is slightly less than 3mm.

A ring groove with a width of 3mm on the outer circle of the oiler is used as the focus of the tooling. The tooling is composed of two upper and lower hoops. When in use, it is locked by two connecting screws. The shoulder is stuck in the groove of the oiler. The cross-section of the ring groove of the device is closely attached, and the inner diameter of the tooling and the outer diameter of the oiler are tightly hugged to ensure uniform force. After the tooling is installed, the fitter uses two screws to insert into the threaded hole on the end face of the tooling, and slowly push it out with force, so as to ensure that the oiler is not deformed, broken or damaged.

In addition to the above-mentioned embodiments, the utility model also includes other implementation modes, and any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the claims of the utility model.
