Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to following institute
It states.
As shown in Fig. 1 ~ 4, a kind of drive shaft disassembling tool, including puller body 2, supporting sleeve 1 and pull rod 3, the puller
Body 2 is stepped cylindrical, and 2 small column one end of puller body connects supporting sleeve 1, and puller body 2 is connected with supporting sleeve 1 by positioning screw 10
It connects, 10 one end of positioning screw is located in the annular groove of puller body 2, and connection in this way can allow puller body 2 and supporting sleeve 1 to turn relatively
Dynamic, limitation axial movement, supporting sleeve 1 is hollow cylindrical structure, and axis is provided between supporting sleeve 1 and the stair-step of puller body 2
7 are held, 2 middle part of puller body offers tapped through hole A, and the tapped through hole A of external screw thread and puller body 2 is provided on the pull rod 3
It is threadedly coupled, one end of pull rod 3 is located in the cavity of supporting sleeve 1, and the other end extends to the outside of puller body 2, and pull rod 3 is located at
The end face of one end of supporting sleeve 1 is provided with threaded hole B, and pull rod 3 is threadedly coupled cutting ferrule 4, the other end of pull rod 3 by threaded hole B
Through-hole has been disposed radially, has been provided in through-hole and pulls out loop bar 6, pulling out loop bar 6 by rotation can allow pull rod 3 to be produced with puller body 2
Raw screw-driven, such pull rod 3 can be screwed out, and an outside axial force is generated when pull rod 3 screws out, passes through this power
Drive shaft 8 can be extracted.
Further, the bearing 7 is thrust ball bearing, using thrust ball bearing puller body 2 is flexibly turned
It is dynamic, while bear certain pulling force.
Further, described 2 big cylinder one end of puller body is radially symmetrically arranged with tapped blind hole, and puller body 2 passes through
Tapped blind hole is threadedly coupled extension bar 5.
Further, annular groove is provided on the outside of described 2 small column one end of puller body, supporting sleeve 1 connects with puller body 2
It connects one end and has been disposed radially threaded hole C, threaded hole C internal threads are connected with positioning screw 10.
Further, described 4 one end of cutting ferrule is semicolumn, and semicolumn one end of cutting ferrule 4 offers half circular shape
Slot 11, stepped groove 11 connect the end face of semicolumn, and stepped groove 11 is located at the diameter of the diameter less than the other end of end face one end, cutting ferrule
4 other ends are provided with screw thread and are connect with pull rod 3, and difference can be installed when different driving axis 8 is decomposed using being threadedly coupled
The cutting ferrule 4 of specification completes the decomposition to drive shaft 8.
Further, the inner cavity of described 1 one end of supporting sleeve is provided with ring-shaped step.
The course of work of the present invention is as follows：Drive shaft to be torn open is mounted in cutting ferrule 4, the stepped groove set on cutting ferrule 4
