DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 4 A yoke assembly orientation tool for a rear wheel steering gear of an automobile. The tool assembly is made of steel as a whole. A mounting hole 202 for a yoke positioning rod 208 is designed on a tool base plate 201. After the yoke 212 is installed on the rear wheel steering gear assembly 211, the yoke positioning rod 208 needs to be removed, and the yoke positioning rod 208 can be inserted into the mounting hole 202 of the tool base plate 201, thereby avoiding the loss of the yoke positioning rod and facilitating tool management.

[0030] In this embodiment, the tooling base 201 is currently made of steel, and can also be designed to be made of a lighter material such as aluminum alloy to reduce the weight of the tooling. The tooling base can also be designed with grooves to reduce weight, and can also be designed with mounting holes for installing the tooling base on other equipment.

[0031] Specifically, a handle 203 is designed on the tooling base plate 201. The handle 203 can be made of steel, plastic, or a composite material. The handle 203 is fixed to the tooling base plate 201 by two bolts. Two handles are designed, which is convenient for moving and carrying the tooling.

[0032] In this embodiment, a handle 203 is designed on the tool base 201. Considering that the tool is made of steel and is heavy, the handle 203 can be designed as a hoisting hole so that it can be hoisted, transported or moved by machinery and equipment.

[0033] Specifically, a steering gear quick fixing mechanism 204 is designed on the tooling base plate 201, and the yoke 212 is fixed to the steering gear by bolts. Moreover, the steering gear quick fixing mechanism 204 is a quick release device, and the steering gear assembly 211 can be quickly fixed and removed by pressing the handle.

[0034] In this embodiment, threaded holes may also be designed on the support column without the locating pin installed, and the steering gear assembly may be fixed to the support column and then to the tooling by bolts, so that the steering gear quick fixing mechanism 204 may be replaced.

[0035] Specifically, a steering gear support column 205 is designed on the tooling base plate 201, and a steering gear locating pin 209 is designed on the support column 205, so that the rear-wheel steering gear assembly 211 can be accurately positioned on the tooling, ensuring the installation accuracy of the yoke. Since the rear-wheel steering gear assembly 211 needs to be frequently plugged and unplugged from the steering gear locating pin 209 when assembling the yoke, the steering gear locating pin 209 is made of special steel after heat treatment and has a higher surface roughness level, ensuring the service life of the tooling and easier plugging and unplugging. At the same time, when the steering gear locating pin 209 is severely worn after long-term use and affects the assembly accuracy, it can be replaced without replacing the entire yoke positioning device, so the economic benefits are better.

[0036] Specifically, when the yoke 212 is assembled, the yoke 212 is in direct contact with the positioning block 207 and the yoke positioning rod 208. The positioning block 207 is designed on the positioning rod base 206. The positioning block 207 is made of special steel and is fixed to the positioning rod base 206 by bolts. When the positioning block 207 is severely worn and affects the assembly accuracy of the assembly, it is convenient to replace it.

[0037] In this embodiment, a yoke is fixed to the positioning rod base 206 by two positioning rods. The two positioning rods can be designed to be square movable blocks that are contoured with the mating surface of the yoke, which can also play the role of locating the position of the yoke.

[0038] Specifically, a positioning sleeve is further designed for the connection between the yoke positioning rod 208 and the positioning rod base 206 to further prevent the yoke positioning rod 208 and the positioning rod base 206 from being frequently plugged in and out and causing wear to the positioning rod base 206 .

[0039] In this embodiment, the positioning rod base 206 is currently connected and fixed to the tooling base plate 201 by bolts. The positioning rod base 206 and the tooling base plate 201 can also be designed as an integrated structure. In order to adapt to the assembly of different types of steering gear yokes, the angle between the positioning rod base 206 and the tooling base plate 201 can be customized, and positioning rod bases of different specifications can be customized.

[0040] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
