Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

The violent disassembly of the engine fuel injector results in damage to the fuel injector or the cylinder head, causing unnecessary economic loss. In view of this, the utility model provides an engine fuel injector dismantles frock. The oil sprayer is used for pulling the oil sprayer out of the cylinder cover, and a process screw hole is formed in the oil sprayer to be disassembled.

As shown in fig. 1 to 5, the engine fuel injector dismounting tool in the embodiment of the present invention includes a bracket, a drawing screw rod 3, a connection nut 4, a T-shaped block 5, an operation nut 6, and other components. Wherein:

the support comprises a support body 1 and a support rod 2 connected to the support body 1, wherein a guide hole 11 penetrating through the support body 1 is arranged on the support body 1. In the embodiment shown, a total of two support rods 1 are provided.

The drawing screw rod 3 penetrates through the guide hole 11, and a first external thread is arranged on the drawing screw rod 3.

The connecting nut 4 is fixedly connected to the lower end of the drawing screw rod 3, and second external threads matched with the process screw hole in the fuel injector to be disassembled are arranged on the connecting nut 4.

The T-shaped block 5 is sleeved on the drawing screw rod 3, the diameter of the large head 51 of the T-shaped block 5 is larger than the aperture of the guide hole 11, and the diameter of the small head 52 of the T-shaped block 5 is matched with the aperture of the guide hole 11.

The operation nut 6 is screwed on the drawing screw rod 3 through a first external thread and is positioned above the T-shaped block 5.

The utility model discloses a working process of frock is dismantled to engine injector is as follows:

first, the operating nut 6 is screwed up using a wrench so that the operating nut 6 moves up to the initial high position, and the T-block 5 is pushed down along the extraction screw 3 so that the lower head 52 of the T-block 5 is completely snapped into the guide hole 11 on the support body 1.

The engine fuel injector dismounting tool is integrally placed above a fuel injector to be dismounted, the support body 1 is pressed on the upper end face of the cylinder cover, and the connecting nut 4 extends into a process screw hole in the fuel injector.

And rotating the drawing screw rod 3 and the connecting nut 4 to enable the connecting nut 4 to be completely screwed into the technical screw hole, so that the fixed connection between the engine fuel injector dismounting tool and the engine fuel injector to be dismounted is completed.

The operating nut 6 is screwed down using a wrench, and the operating nut 6 moves down and finally abuts against the large end 51 of the T-block 5.

And increasing the screwing force, continuing screwing the operating nut 6 downwards, and extruding the operating nut 6 and the T-shaped block 5 mutually. Synchronously, the drawing screw rod 3 moves upwards slowly under the action of the operating nut 6 and drives the connecting nut 4 to move upwards synchronously. Under the pulling of the coupling nut 4, the injector is slowly moved away from the cylinder head and finally off the cylinder head. Finally, the oil injector is unscrewed from the connecting nut 4 and the oil injector 2, and the disassembly of the oil injector is finished.
