[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] like Figure 1 、 Figure 2 and Figure 4 As shown, Example 1 of the present invention shows a steering gear running-in platform, comprising a platform 1, with two bilaterally symmetrical transverse fasteners 2 fixedly connected to the top of the platform 1, and a longitudinal fastener 3 fixedly connected to the top of the platform 1, located between the two transverse fasteners 2. The platform 1 serves as a platform for placing the steering gear. The two transverse fasteners 2 are installed on either side of the top of the platform 1 to secure the rack rod sleeve in the steering gear, and the longitudinal fastener 3 is used to secure the steering column in the steering gear, so that the longitudinal fasteners 3 and the transverse fasteners 2 cooperate with each other during the running-in process of the steering gear.

[0028] The transverse fastener 2 includes a mounting plate 20, with a movable slot 22 defined in the middle. A limit rod 23 is laterally fixedly connected to the inner side of the movable slot 22. Guide rails 21, located on either side of the movable slot 22, are fixedly connected to the top of the mounting plate 20. The limit rods 23 and the outer sides of the guide rails 21 are both slidably connected to an adjustment assembly 24. When the adjustment assembly 24 secures the rack rod sleeve and the steering column is rotated, the rack rod sleeve moves left and right, and the adjustment assembly 24 slides left and right outside the guide rails 21 and limit rods 23, causing the adjustment assembly 24 and the rack rod sleeve to move synchronously. The guide rails 21 and limit rods 23 enhance the stability of the adjustment assembly 24 during movement, keeping its movement angle consistent and enhancing the running-in condition of the steering gear.

[0029] The longitudinal fastener 3 comprises a housing 30 with adjustment openings 31 on either side. An adjustment column 32 is sleeved within the housing 30. Threaded rods 33 located within the adjustment openings 31 are fixedly connected to the left and right sides of the adjustment column 32. A fixing knob 34 is threadedly connected to the outer surface of the threaded rod 33. A mounting clamp 35 is fixedly mounted on the top of the adjustment column 32. The end of the steering column closest to the steering wheel is placed on top of the adjustment column 32, covered with the mounting clamp 35, and then secured with bolts. The mounting clamp 35 and the adjustment column 32 secure the steering column. The adjustment column 32 can then be adjusted based on the height of the connection between the steering column and the rack rod sleeve. The adjustment column 32 can move up and down within the housing 30. Once the position is adjusted, the fixing knob 34 is tightened to secure the adjustment column 32.

[0030] like Figure 2 As shown, in Example 2 of the present invention, the steering gear running-in platform, based on Example 1, has a limit rod 23 with its ends fixedly connected to the left and right walls of the movable groove 22, respectively. Limit slots are defined on both the front and rear sides of the limit rod 23. An adjustment assembly 24 is located within the movable groove 22. To enhance stability and smoothness during the sliding of the adjustment assembly 24, a limit rod 23 is provided to provide auxiliary positioning.

[0031] like Figure 3 As shown, the steering gear running-in table of Example 3 of the present invention is based on Example 1, and the adjustment component 24 includes a movable base 240, a horizontal mounting hole is opened inside the movable base 240, and a ball sleeve 241 is fixedly connected inside the mounting hole, and a fixed clamping block 242 is fixedly connected to one side of the top of the movable base 240, and the top of the fixed clamping block 242 is fixedly connected to two connecting heads 243, and the outside of the connecting head 243 is movably connected to a flap 244, and two adjustment slots 245 are opened on the other side of the top of the movable base 240, and the internal sliding connection of the adjustment slot 245 is connected to a limit block 246, and the top of the limit block 246 is fixedly connected to the bottom of the movable clamping block 247, and the top of the movable clamping block 247 is fixedly connected to two symmetrical fixing rods 248, and the fixing rod 248 and the flap 244 are sleeved at one end away from the connecting head 243, and the external thread of the fixing rod 248 away from the movable clamping block 247 is connected to a fixing nut 249. Place the two ends of the gear rod sleeve on the two movable bases 240 respectively, push the movable clamp 247 to clamp the gear rod sleeve with the fixed clamp 242, then rotate the flap 244 to make it engage with the fixed rod 248 on the movable clamp 247, and finally tighten the fixing nut 249 to fix the gear rod sleeve, so that the adjustment component 24 can move synchronously with the gear rod sleeve. During the movement, the ball inside 210 will roll in the limit groove opened on the outside of the limit rod 23, which can increase the movement smoothness and stability of the adjustment component 24.

[0032] like Figure 3 As shown, the steering gear running-in station of Example 4 of the present invention is based on Example 3. In addition, the bottoms of both sides of the movable base 240 are provided with sliding grooves, which are slidably connected to the guide rails 21. The sliding grooves are used to limit the movement of the movable clamping block 247, so that the positions of the movable clamping block 247 and the fixed clamping block 242 are accurately aligned, and the positions of the fixed rod 248 and the flap 244 are also accurately aligned.

[0033] like Figure 3 As shown, Example 5 of the steering gear running-in station of the present invention is based on Example 3. The flap 244 is "H"-shaped, and a limited opening is defined at the end of the flap 244 away from the connector 243. The limited opening is engaged with the fixed rod 248. The width of the movable clamping block 247 and the fixed clamping block 242 can be selected according to the gear rod sleeve. To enhance the fixing effect, double-end fixation is adopted. The "H" shape of the flap 244 is designed to synchronize the opening and closing of both ends.

[0034] like Figure 3 As shown, the steering gear running-in station of Example 6 of the present invention is based on Example 3, and protective pads are attached to the opposite sides of the fixed clamping block 242 and the movable clamping block 247. The addition of the protective pads can enhance the tightening and protection effect of 357 and the fixed clamping block 242 on the rack rod sleeve, improving the fixing ability and preventing damage to the rack rod sleeve during the running-in process.

[0035] like Figure 4 As shown, the steering gear running-in platform of Example 6 of the present invention is based on Example 1, and an inclined placement groove is opened on the side opposite the adjustment column 32 and the mounting clamp 35. The steering column is generally installed at an angle during use, and in order to improve the running-in efficiency, this setting is more in line with the actual situation.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
