[0002] The automotive steering structure is a key system for achieving vehicle directional control. Its core function is to transmit the driver's steering input to the wheels, enabling the vehicle to travel along the intended path. New energy refers to renewable or low-carbon energy. The production of power steering structure parts for new energy vehicles requires the use of journal positioning mechanisms. For example, the production of steering knuckles requires the use of journal positioning mechanisms. During the processing or assembly process, this mechanism ensures the concentricity of the steering knuckle journal and the wheel hub bearing, as well as adapts to the journal structure of different vehicle models.

[0003] Currently, there are still some shortcomings in the journal positioning mechanism, such as the inability to adjust the positioning position of the steering knuckle journal.

[0004] To overcome the problem of inconvenient adjustment of journal positioning mechanism, the prior art (publication number: CN210818456U) Chinese patent discloses a support journal positioning mechanism and a processing device for steering knuckle. The support journal positioning mechanism can position the support journal part of steering knuckles of different diameters, thereby achieving the beneficial effect of using the same fixture for multiple steering knuckle models.

[0005] However, the journal positioning mechanism currently in use still has certain shortcomings. The above document can position the journals of steering knuckles of different diameters, but this structure achieves positioning through a lead screw, which is relatively troublesome to operate and has insufficient positioning effect on the journals. Therefore, it is necessary to improve the existing structure. Summary of the Invention

[0007] To achieve the above objectives, this utility model provides the following technical solution: a journal positioning mechanism for the production of power steering structures for new energy vehicles, comprising a base plate, wherein a steering knuckle is connected to the center of the top of the base plate.

[0008] The top of the base plate is symmetrically provided with through slots, and three sets of through slots are provided around the center of the base plate. A fixing block slides through the through slot, and a connecting seat is fixed to the end of the fixing block. The connecting seat and the fixing block are located on the upper and lower sides of the base plate, respectively.

[0011] Furthermore, a triangular plate is fixed to the bottom of the rotating ring, the output end of the motor is connected to the center of the triangular plate, and rotating blocks are connected to both the top of the triangular plate and the bottom of the fixed block.

[0012] Furthermore, the rotating blocks are provided in three sets, with a rotating rod rotatably connected between two rotating blocks, and a pressing block connected to the top of the connecting seat, with a guide rod sliding through the inside of the pressing block.

[0013] Furthermore, the adjustment mechanism includes a sliding block, which is fixed to the top of the connecting seat and located between two guide rods, and slides through the inside of the extrusion block.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1, such as Figures 1-4 The present invention provides the following technical solution to address the problem that the journal positioning mechanism is inconvenient for fixing the steering knuckle 2: A pressing mechanism is disclosed.

[0029] The base plate includes a base plate 1, with a steering knuckle 2 connected to the center of its top. A through slot 101 is symmetrically formed at the top of the base plate 1, with three sets of through slots 101 arranged around the center of the base plate 1. A fixing block 103 slides through the through slot 101, and a connecting seat 102 is fixed to the end of each fixing block 103. The connecting seat 102 and the fixing block 103 are located on the upper and lower sides of the base plate 1, respectively. A pressing mechanism to improve the journal positioning stability is provided inside the base plate 1. The pressing mechanism includes a fixing ring 104, which is fixed to the center of the bottom of the base plate 1. A motor 105 is installed near the bottom center of the fixed ring 104. A rotating ring 106 is rotatably connected through the fixed ring 104. A triangular plate 107 is fixed at the bottom of the rotating ring 106. The output end of the motor 105 is connected to the center of the triangular plate 107. Rotating blocks 108 are connected to the top of the triangular plate 107 and the bottom of the fixed block 103. There are three sets of rotating blocks 108. A rotating rod 109 is rotatably connected between two rotating blocks 108. A pressing block 110 is connected to the top of the connecting seat 102. A guide rod 111 slides through the pressing block 110.

[0030] When using the journal positioning mechanism, first place the steering knuckle 2 at the center surface of the base plate 1, then start the motor 105. When the motor 105 starts, the output end can drive the triangular plate 107 to rotate. When the triangular plate 107 rotates, it can drive the rotating ring 106 to rotate. When the rotating ring 106 rotates, it can rotate through the fixed ring 104. When the triangular plate 107 rotates, it can drive the three rotating blocks 108 to rotate. When the rotating blocks 108 rotate, they can pull the fixed block 103 to move through the rotating rod 109. When the fixed block 103 moves, it can slide through the through slot 101. When the fixed block 103 slides, the rotating rod 109 can rotate through the two rotating blocks 108. When the fixed block 103 slides, it can also drive the connecting seat 102 to move. When the connecting seat 102 moves, it can drive the pressing block 110 to move. When the three pressing blocks 110 move to the side of the steering knuckle 2, they can perform pressing and positioning, which improves the efficiency and stability of the journal mechanism in positioning the steering knuckle 2.

[0031] Example 2, as follows Figure 1 , Figure 5 and Figure 6The present invention provides the following technical solution: In order to solve the problem that the journal positioning mechanism is difficult to adapt to the specifications of the steering knuckle 2, an adjustment mechanism is disclosed based on the first embodiment: a guide rod 111 is symmetrically fixed on the top of the connecting seat 102, and an adjustment mechanism to improve the adaptability of the positioning mechanism to the steering structure is provided on the top of the connecting seat 102. The adjustment mechanism includes a sliding block 112, which is fixed on the top of the connecting seat 102 and is located between the two guide rods 111. The sliding block 112 slides through the extrusion block 110. A toothed plate 113 is installed inside the side of the sliding block 112. A gear 114 is meshed on the side of the toothed plate 113. A threaded block 115 is fixed on the side of the gear 114. The threaded block 115 rotates inside the extrusion block 110 through a bearing. A threaded ring 116 is threadedly connected to the surface of the threaded block 115.

[0032] Due to differences in vehicle type, the type and size of the steering knuckle 2 also vary. To improve the positioning stability of the steering knuckle 2, the pressing block 110 can be pushed upwards before pressing the steering knuckle 2. When the pressing block 110 is pushed upwards, it can drive the gear 114 to move. When the gear 114 moves, it can mesh and rotate with the gear plate 113. When the gear 114 meshes and rotates, it can drive the threaded block 115 to rotate. When the threaded block 115 rotates, it can rotate inside the pressing block 110 through the bearing. When the gear 114 rotates, the pressing block 110 can slide upwards through the guide rod 111 and the sliding block 112. After the pressing block 110 slides upwards to the designated position, do not move it manually, and then move the threaded ring 1. The threaded ring 116 rotates to the end of the threaded block 115. When the threaded ring 116 rotates, it can slide through the threaded block 115. When the threaded ring 116 slides to the side of the pressing block 110, it can be pressed. When the threaded ring 116 is pressed, it can drive the gear 114 to be positioned, preventing the gear 114 from rotating. When the gear 114 is not rotating, it can be positioned by the meshing teeth of the toothed plate 113. After the gear 114 is positioned, it can drive the pressing block 110 to be positioned. After the pressing block 110 is positioned, its height can be adjusted according to the length of the steering knuckle 2, so that the pressing block 110 can be quickly adjusted according to the size and type of the steering knuckle 2, which improves the adaptability of the journal positioning mechanism to the steering knuckle 2.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
