The invention relates to the technical field of equipment used for dismounting parts and provides a tool for dismounting a part in a hole. The tool comprises an expansion portion and a dismounting power portion, the expansion portion is used for being placed in the hole and provided with a clamping face, and the clamping face is used for being clamped with the part in the hole; the dismounting power portion is connected with the expansion portion and used for taking the expansion portion out of the hole. By the adoption of the structure, firstly, the part in the hole is fixed through variation of the diameter of the expansion portion, then through cooperation of the dismounting power portion, thereby the part can be taken out of the hole in an easy, convenient and labor-saving mode, and meanwhile the part is not prone to damage; in addition, the clamping face is in face contact with the part, the contact area between the expansion portion and the part is increased, thereby connection between the expansion portion and the part can be firmer, and the situation that the part slides down from the expansion portion in the process when the part is taken out is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of equipment used for dismantling parts, in particular to a dismantling tool for parts in holes. Background technique [0002] When repairing assembly parts such as construction machinery and vehicles, it is usually necessary to disassemble the bearings and sleeves in the mounting holes to facilitate maintenance; in the prior art, since the bearings, sleeves and other parts are interference fit , when disassembling, it takes a lot of force to pull it out or pull it out. [0003] For the bearing or sleeve installed in the blind hole, it cannot be pushed outward, and can only be taken out by pulling; while using the traditional triangular tensioner, because there is no suitable force application position or the contact mode between the tensioner and the bearing or sleeve is The point contact with a relatively narrow position is not firm enough, so it is difficult to pull out the bearing and sleeve, and if the...
