[0019] The utility model will be described in detail below with reference to the accompanying drawings by the example embodiment of the utility model. It should be pointed out that the following detailed description of the utility model is only for the purpose of illustration, and is not limited to the utility model.

[0020] The utility model provides a extrusion type disassembling tool for the bolt through the bearing in the narrow space, and the tool is used for the bolt through the bearing in the narrow space to be disassembled, can avoid the product damage risk caused by disassembling bolt, simplify the operation difficulty, and guarantee the disassembly quality.

[0021] Reference Figure 1 As the extrusion type disassembling tool for the bolt through the bearing in the narrow space of the example embodiment of the utility model includes arch-shaped piece 1, screw rod 2 and top rod 3.

[0022] The two ends of the arch-shaped piece 1 are opposite to each other, one end is provided with a through hole, especially a circular through hole, for coaxially penetrating the head of the bolt to be disassembled, and the size of the end of the arch-shaped piece 1 is smaller, for example, for the bolt connecting the nacelle cover and the engine body, the end can enter the space of 35mm between the screw end and the engine structure, and the space occupied during disassembling the bolt is small. The other end of the arch-shaped piece 1 is provided with a threaded hole coaxial with the through hole, for forming a kinematic pair with the screw rod 2.

[0023] In combination Figure 2 The screw rod 2 is screwed into the threaded hole of the arch-shaped piece 1 and moves relative to the arch-shaped piece 1, and one end of the screw rod 2 away from the through hole of the arch-shaped piece 1 is provided with a clamping part 21 for the wrench clamping, and the clamping part 21 is particularly a hexagonal head for facilitating the wrench clamping.

[0024] The ejector rod 3 is coaxially arranged at one end of the screw rod 2 facing the through hole of the arch-shaped piece 1 and abuts against the end face of the rod part of the bolt to be disassembled, so as to move with the screw rod 2 and press the bolt to be disassembled, thereby completing the disassembly of the bolt to be disassembled. In other words, the ejector rod 3 is located in the arch-shaped piece 1, one end of the screw rod 2 is located in the arch-shaped piece 1, and the other end is located outside the arch-shaped piece 1 for the wrench clamping, so as to perform the bolt disassembly operation.

In addition, the diameter of one end of the ejector rod 3 contacting the bolt to be disassembled is substantially equal to the diameter of the bolt rod part, and the diameter of the end engaging with the screw rod 2 can be slightly larger, so as to process the recess part to receive the protruding part of the screw rod 2. Preferably, the matching surfaces of the protruding part 22 and the recess part are tapered surfaces.

[0026] The working process of the bolt disassembly tool provided by the utility model is as follows: the head of the bolt to be disassembled is arranged at the through hole of one end of the arch-shaped piece 1, the screw rod 2 is screwed on the other end, and the ejector rod 3 is arranged to abut against the bolt tail at one end and engage with the screw rod 2 at the other end. At this time, the clamping part 21 of the screw rod 2 is rotated by using the open wrench, the screw rod 2 moves forward along the threaded pair, and the ejector rod 3 is driven to eject the bolt to be disassembled. Therefore, for the bolt passing through the bearing in a narrow area and being difficult to disassemble due to rust and deformation, the bolt is disassembled by the screw rod pressing the bolt at the end face of the bolt rod part, the pressing force is large, the space occupied is small, and the bolt can be quickly disassembled simply and conveniently.
