Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Figure 1, for a kind of embodiment of the utility model is for dismantling the specific purpose tool overall schematic of vehicle semiaxle bearing.Described specific purpose tool comprises:
As shown in Figure 2, cylindrical body 1, the inside of described cylindrical body 1 is cavity, for holding vehicle semiaxle; One end of cylindrical body 1 is fixed with two holders 12 that are oppositely arranged, and the termination of the other end is fixed with nut 14;
The first jaw 2, described the first jaw 2 is hinged on one of them holder 12;
The second jaw 3, described the second jaw 3 is hinged on another holder 12;
As shown in Figure 4, be the first jaw schematic diagram of a kind of embodiment of the utility model.Described the first jaw 2 and the second jaw 3 mirror image symmetries, be arcuate structure, and its one end has teeth 22, and the other end has connecting hole 24.The effect of teeth 22 is in unloading process, to clamp bearing edge, and the effect of connecting hole 24 is by pivot, jaw to be hinged on holder 12, and jaw can be rotated around pivot, is convenient to the adjustment of opening between jaw.
As shown in Figure 5, screw rod 4, the external screw thread of described screw rod 4 matches with the internal thread of described nut 14, and screw rod 4 is screwed in described nut 14, and one end of screw rod 4 is for screwing 42, and the other end is thimble 44.
