[0042] For better understanding of the above technical solutions, the technical solutions of the embodiments of the present application are described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, but not limitations of the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0043] As shown in Figures 1-2 The first aspect of the embodiments of the present application proposes a fuel injector gasket taking-out device, which comprises a taking-out part 100, the taking-out part 100 comprising a connecting rod 110 and a clamping block 120, the clamping block 120 being connected to one end of the connecting rod 110, the clamping block 120 being used to pass through the gasket to be on the side of the gasket away from the connecting rod 110, and a knocking part 200, the knocking part 200 being used to knock the gasket to make the gasket deform.

[0044] The fuel injector gasket taking-out device provided by the embodiments of the present application comprises a taking-out part 100 and a knocking part 200, wherein the taking-out part 100 comprises a connecting rod 110 and a clamping block 120, the clamping block 120 being connected to one end of the connecting rod 110, the clamping block 120 being used to pass through the gasket to be on the side of the gasket away from the connecting rod 110, and the knocking part 200 being used to knock the gasket to make the gasket deform. In actual use, first, the fuel injector is taken out to expose the gasket on the lower side of the fuel injector, then the clamping block 120 of the taking-out part 100 is passed through the round hole on the gasket through the connecting rod 110 and sent to the lower side of the gasket, then the gasket is knocked by the knocking part 200 to make the gasket deform and enable the gasket to clamp the clamping block 120, then the taking-out part 100 is lifted to take out the clamping block 120 to take out the gasket, and finally the taking-out work of the gasket is completed. The present application is designed according to the structural features of the cylinder head assembly, solves the technical problem of difficulty in taking out the fuel injector gasket, and improves the taking-out efficiency of the fuel injector gasket.

[0045] As shown in Figures 1-2 The taking-out part 100 further comprises a sliding hammer 130 and a holding groove 140, the sliding hammer 130 being slidingly connected to the connecting rod 110, and the holding groove 140 being formed in the sliding hammer 130.

[0046] In the technical scheme, the taking-out part 100 further comprises a sliding hammer 130 and a holding groove 140, the sliding hammer 130 is slidably connected to the connecting rod 110, and the holding groove 140 is arranged on the sliding hammer 130. In the process of taking out the gasket, the gasket is adhered to the cylinder head assembly due to high temperature, which makes it difficult to take out. Only relying on the lifting of the clamping block 120, sometimes it is still difficult to take out. Therefore, the sliding hammer 130 is added, and the sliding hammer 130 is sleeved and connected to the connecting rod 110. It can be understood that the sliding hammer 130 is made of metal with high density. In actual use, the sliding hammer 130 is lifted to a certain height and then freely falls, so that the gasket is impacted by the sliding hammer 130 and loosened, and the gasket can be easily taken off from the cylinder head assembly. Further, the holding groove 140 is arranged on the sliding hammer 130, so that the operator can hold the sliding hammer 130, and the usability of the technical scheme is further improved.

The stop block 150 can prevent the sliding hammer 130 from falling off the connecting rod 110, and also provides a convenient holding structure for the connecting rod 110. At the same time, the sliding hammer 130 is quickly lifted and impacts the stop block 150. The inertia of the sliding hammer 130 can also exert an upward force on the stop block 150. The force is transmitted to the gasket through the connecting rod 110, which can further improve the efficiency of taking out the gasket of the oil injector.

After the clamping block 120 is sent to the side of the gasket away from the connecting rod 110 through the connecting rod 110, the connecting rod 110 can be removed. Then the gasket is hammered by the knocking part 200. During the knocking process, the interference of the connecting rod 110 on the knocking part 200 can be avoided, which facilitates the hammering of the gasket by the knocking part 200, and further improves the usability of the present application.
