Furthermore, a central hole at the bottom of the shell of the steering gear and a central hole of the upper installation guide disc are processed concentrically.
Furthermore, the guide block comprises a connecting part and an outer ring fixing part which are integrally formed; the outer diameter of the connecting part is a conical surface matched with the inner diameter of the outer ring of the bearing to be pressed in, and the bottom end of the outer ring fixing part is in interference fit with the edge of the bottom of the inner diameter of the outer ring of the bearing to be pressed in.
Furthermore, the outer ring fixing part is provided with four locking claws, and annular grooves are formed in the inner sides of the locking claws and can increase the elasticity of the locking claws.
Preferably, one end of the pressing rod fixing pressing block is provided with a threaded blind hole, and a screw penetrates through the pressing block from one side of the pressing block to be connected with the threaded blind hole.
Preferably, the guide block is connected with the pressing block through a plurality of socket head cap screws.
Furthermore, the guide block is made of elastic materials.
Preferably, the elastic material is a nylon material.
Furthermore, the other end of the pressure rod is connected with a press machine, and the press machine drives the pressure rod.
The invention has the beneficial effects that: when the outer ring of the tapered roller bearing is pressed in from the first side of the steering gear shell, the outer ring is centered, the bearing crush caused by the pressing-in deflection of the outer ring of the bearing is avoided, the structure is simple, the operation is convenient, and the working efficiency is improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The centering press-in tool for the outer ring of the tapered roller bearing for the steering gear comprises a guide disc 1, a pressure rod 2, a pressing block 3 and a guide block 4; one end of the pressure rod 2 is detachably connected with a pressing block 3, and the pressing block 3 is detachably connected with a guide block 4; bearing inner race 5 is fixed on guide block 4, and 4 bottoms of guide block and the 5 contact site interference fit of bearing inner race of waiting to impress, depression bar 2 and the cooperation of 1 hole of deflector, deflector 1 and steering gear casing hole cooperation.
Further, the central hole at the bottom of the shell 6 of the steering gear and the central hole of the upper installation guide disc 1 are processed concentrically.
Further, the guide block 4 comprises a connecting part 3.1 and an outer ring fixing part 3.2 which are integrally formed; the outer diameter of the connecting part 3.1 is a conical surface matched with the inner diameter of the bearing outer ring 5 to be pressed in, and the bottom end of the outer ring fixing part 3.2 is in interference fit with the bottom edge of the inner diameter of the bearing outer ring 5 to be pressed in.
Furthermore, the outer ring fixing part 3.2 is provided with four locking claws, the inner sides of the locking claws are provided with annular grooves 7, and the elasticity of the locking claws can be increased by the annular grooves 7.
Preferably, one end of the pressing rod 2 for fixing the pressing block 3 is provided with a threaded blind hole, and a screw penetrates through the pressing block 3 from one side of the pressing block 3 and is connected with the threaded blind hole.
Preferably, the guide block 4 is connected with the pressing block 3 through a plurality of socket head cap screws.
Further, the guide block 4 is made of an elastic material and is a guide block 4.
Preferably, the elastic material is a nylon material.
