[0005] Lower die seat;

[0006] Its characterized in that: the middle part of the top surface of the lower die seat is equipped with a limiting slot, the lower side of the limiting slot is equipped with a guide hole which is communicated with the limiting slot, the top end of the guide hole is inserted with a mandrel, the outer wall of the mandrel is equipped with an annular support platform near the middle part, and the top end of the mandrel is equipped with an upper die rod.

[0007] In the above structure, the bottom end surface of the upper die rod is equipped with a ring-shaped convex.

[0008] Compared with the prior art, the bearing installation tool of the utility model has the beneficial effects that: the bearing installation tool of the utility model has reasonable structure design, the installation of bearing and bearing seat is realized through the mutual cooperation of the mandrel and the lower die seat, the structure is simple, the operation is convenient, and the production cost is reduced. BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1 It is the structure schematic diagram of the bearing installation tool of the utility model embodiment;

[0010] Figure 2 It is the use state reference drawing of the bearing installation tool of the utility model embodiment.

[0011] In the drawing:

[0012] 1, lower die seat;2, limiting slot;3, guide hole;4, mandrel;5, annular support platform;6, upper die rod;7, ring-shaped convex;8, bearing;9, bearing seat. DETAILED DESCRIPTION

[0013] The specific implementation of the utility model will be described in further detail in combination with the drawings and embodiments. The following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.

[0014] like Figure 1-2 As shown, a bearing installation tool includes:

[0015] Lower die base 1;

[0016] It is characterized in that: a limiting groove 2 is provided in the middle part of the top surface of the lower mold base 1, a guide hole 3 connected to the limiting groove 2 is provided below the limiting groove 2, a core shaft 4 is inserted into the top end of the guide hole 3, an annular support platform 5 is provided on the outer wall of the core shaft 4 near the middle part, and an upper mold rod 6 is sleeved on the outer wall of the top end head of the core shaft 4.

[0017] In the above structure, a circle of annular protrusions 7 is provided on the bottom end surface of the upper mold rod 6.

[0018] During operation, the bearing installation tool of the present invention connects the upper die rod to the radial drill, inserts the bearing 8 above the annular support platform 5 of the mandrel 4, and inserts the top end of the mandrel 4 into the bottom end surface of the upper die rod 6. The bottom end of the mandrel 4 is inserted into the bearing seat 9 and inserted into the guide hole 3. The bottom end surface of the lower die seat contacts the radial drill table. The radial drill is started, and the upper die rod is driven downward to press the bearing into the bearing seat.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
