[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 5 , and describes the application in detail with reference to embodiments. Example 1

[0023] Embodiment 1 discloses a vehicle steering knuckle processing and positioning device, referring to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 The positioning device includes a base 1 and a carrying plate 14 .

[0024] Specifically, in order to support the first telescopic rod 3 and the second telescopic rod 5 without affecting the operation of other components in the device, two support seats 2 are fixedly installed on one side above the base 1, and the two support seats 2 are rotatably connected to the lower ends of the first telescopic rod 3 and the second telescopic rod 5 respectively. In order to facilitate the first telescopic rod 3 to better support the second telescopic rod 5, a slider 4 is provided at the retractable end of the first telescopic rod 3. In order to facilitate the assembly and stability of various components of the device, a support plate 6 is detachably installed above the base 1, and a first vertical plate 7 is provided above the support plate 6. A triangular star through hole 8 is provided inside the first vertical plate 7. A second vertical plate 9 is provided on one side of the first vertical plate 7. An L-shaped through hole 10 is provided inside the second vertical plate 9 to facilitate adjustment of the angles of the column 11 and the bearing plate 14. A column 11 is provided between the first vertical plate 7 and the second vertical plate 9, and a lower end of the column 11 is provided There is a first connecting shaft 12, and a second connecting shaft 13 is arranged above the first connecting shaft 12, which helps to further ensure the stability of the column 11 and the bearing plate 14, and is convenient for fixing the column 11 between the first upright plate 7 and the second upright plate 9, so that the whole device can run smoothly. In order to facilitate the placement of the steering knuckle, a bearing plate 14 is arranged at the top of the column 11, and an annular groove 17 is arranged above the middle of the bearing plate 14, and a limiting axis 18 is arranged in the middle of the annular groove 17, which can realize the preliminary positioning of the steering knuckle. In order to further position the steering knuckle, a plurality of blocks 19 are arranged on the outer side of the annular groove 17, and a slide groove 20 is arranged below one side of the block 19, and a limiting block 21 is arranged at one end of the slide groove 20, and a pressure plate 22 is arranged above the limiting block 21, and a rotating shaft 23 is arranged at one end of the pressure plate 22, so that the device can be suitable for positioning during the processing of steering knuckles of different specifications.

[0025] In order to ensure that the first telescopic rod 3 stably supports the second telescopic rod 5 while providing power for the second telescopic rod 5 to rotate along the support seat 2, the device is designed so that the vertical projections of the first telescopic rod 3 and the second telescopic rod 5 coincide. In order to reduce the influence of the slider 4 on the operation of the second telescopic rod 5, the slider 4 and the second telescopic rod 5 form a ring connection.

[0026] In order to ensure the stability of the device, the first vertical plate 7 is fixedly connected to the support plate 6. The upper ends of the first vertical plate 7 and the second vertical plate 9 are both L-shaped, which helps to adjust the angles of the column 11 and the supporting plate 14. For the convenience of assembly, the first vertical plate 7 and the second vertical plate 9 are detachably connected, and the bottom horizontal positions of the triangular star through hole 8 and the L-shaped through hole 10 are on the same horizontal plane.

[0027] In order to further ensure the stability of the device during operation, the first connecting shaft 12 is penetrated and arranged at the lower end of the column 11, and one end of the first connecting shaft 12 is slidably connected with the triangular star through hole 8, which is convenient for limiting the column 11 and providing convenience for adjusting the angle of the column 11. The second connecting shaft 13 is penetrated and arranged inside the column 11, and the end of the second connecting shaft 13 away from the column 11 passes through the L-shaped through hole 10 and is engaged with the retractable end of the second telescopic rod 5. The second connecting shaft 13 and the L-shaped through hole 10 are slidably connected, which further limits the position of the column 11, so that the second telescopic rod 5 can control the angle and position of the column 11 through the second connecting shaft 13.

[0028] In order to facilitate the assembly and installation of various components in the device and make the device adaptable to production, the rotation angle range of the column 11 is designed to be greater than or equal to 0 degree and less than or equal to 90 degrees.

[0029] A support shaft 15 and a spring 16 are connected between the annular groove 17 and the bearing plate 14, and a limit shaft 18 is detachably connected to the annular groove 17. A support shaft 15 and a spring 16 are connected between the limit block 21 and the stop block 19, so as to prevent the spring 16 from changing its position during the squeezing process and further position the steering knuckle through the rebound tendency of the spring 16 and the support shaft 15.

[0030] The present embodiment 1 is a disclosed automobile steering knuckle processing and positioning device. Before actual use, it needs to be placed on a plane, and then check whether the connection between the various components is stable and whether the side of the column 11 is perpendicular to the upper plane of the base 1. If not, it is necessary to make corresponding corrections. After checking and correcting, it can be put into use. When in use, let the first telescopic rod 3 and the second telescopic rod 5 be in a closed state, first remove the limit shaft 18 from the annular groove 17, and then place the steering knuckle without a center hole on the top of the annular groove 17 at the center of the bearing plate 14, and gently press the upper part of the steering knuckle by hand to squeeze the annular groove 17 and the spring 16 and the support shaft 15 below it, so that the lower part of the steering knuckle is close to the bearing plate 14. In the process of pressing down, the edge of the steering knuckle squeezes the limit block 21 to achieve initial positioning of the steering knuckle. Positioning, gently turn the steering knuckle so that its top is in contact with the pressure plate 22, then release the hand pressing the steering knuckle, rotate the rotating shaft 23 so that the bottom of the rotating shaft 23 is tightly fitted with the steering knuckle, to achieve further positioning of the steering knuckle, and then start the external processing equipment to open a center hole at the position of the center hole. Since the inside of the annular groove 17 is hollow, it can ensure that the center hole is opened smoothly while avoiding the loss of the annular groove 17 and the external processing equipment. After the center hole is opened, rotate the rotating shaft 23 to separate the bottom of the rotating shaft 23 from the steering knuckle, push the limit block 21 along the slide groove 20 toward the direction of the stop block 19, remove the steering knuckle, clean up the production waste, and after the production waste is cleaned up, assemble the limit shaft 18 and the annular groove 17 together, and then repeat the above positioning, processing and cleaning steps to process the steering knuckle.

[0031] After the above operation is completed, the first telescopic rod 3 and the second telescopic rod 5 are started, and the column 11 and the load-bearing plate 14 and the components above them together with the steering knuckle are adjusted to a suitable height by controlling the extension or retraction of the second telescopic rod 5. Then, the first telescopic rod 3 and the second telescopic rod 5 are closed to fix the position of the steering knuckle. Subsequently, the steering knuckle is further processed using an external machine. The above operation enables the same steering knuckle to adapt to different types of external processing machines. Then, the first telescopic rod 3 and the second telescopic rod 5 are started, so that the first telescopic rod 3 drives the second telescopic rod 5 to rotate along the support seat 2. During the rotation, the second telescopic rod 5 retracts and drives the column 11 through the second connecting shaft 13 to change the angle of the column 11, thereby adjusting the angle of the steering knuckle. The angle scales on both sides of the L-shaped through hole 10 are convenient for observing and determining the position after the angle adjustment. When the angle is adjusted to the required angle, the first telescopic rod 3 and the second telescopic rod 5 are closed, and the external processing machine is started to process the steering knuckle. The first telescopic rod 3 provides rotational power for the second telescopic rod 5 while providing support for the second telescopic rod 5, which effectively ensures the stability of the steering knuckle during processing. After the processing is completed, the above-mentioned angle adjustment, processing and other operation steps are repeated until the processing is completed. At this time, the rotating shaft 23 is rotated and the limit block 21 is pushed to release the positioning of the steering knuckle, the steering knuckle is removed, the first telescopic rod 3 and the second telescopic rod 5 are started and closed after the column 11 is reset, and the production waste remaining in the device is cleaned up. After the cleaning is completed, the device is completed. Example 2

[0032] Embodiment 2 is a disclosed automobile steering knuckle processing and positioning device, which is suitable for the case where the side of the column 11 is perpendicular to the plane on the base 1. Figure 5 The similarities between the present embodiment 2 and the embodiment 1 are not described again. The difference between the present embodiment 2 and the embodiment 1 lies in the structure of the first vertical plate 7 and the additional U-shaped baffle plate 24 and the cover plate 25.

[0033] The automobile steering knuckle processing and positioning device disclosed in this embodiment 2 is used in the same manner as in embodiment 1, and no further explanation is given. The difference of this embodiment 2 is the inner wall structure of the first vertical plate 7, in which a U-shaped baffle plate 24 and a cover plate 25 are additionally provided, which is suitable for the situation where the side of the column 11 is perpendicular to the plane on the base 1. In order to prevent production waste from entering between the first vertical plate 7 and the second vertical plate 9 from the triangular star through hole 8 during the steering knuckle processing and affecting the processing, a triangular star slide groove is opened on the inner side of the first vertical plate 7, and the side of the triangular star slide groove away from the second vertical plate 9 is the bottom of the triangular star slide groove, and the space between the first vertical plate 7 and the second vertical plate 9 is formed. A U-shaped baffle plate 24 is provided on one side of the second vertical plate 9, and a gap is left between the U-shaped baffle plate 24 and the first vertical plate 7 and the second vertical plate 9. A cover plate 25 that fits the edge shape of the first vertical plate 7 and the second vertical plate 9 is provided above the first vertical plate 7 and the second vertical plate 9. During the use of the device, the lower end of the cover plate 25 is placed in the gap between the U-shaped baffle plate 24 and the first vertical plate 7 and the second vertical plate 9 so that the edge of the cover plate 25 fits the L-shaped edge of the first vertical plate 7, which can effectively prevent production waste from entering the cavity between the first vertical plate 7 and the second vertical plate 9 during the steering knuckle processing, save maintenance costs, and improve production efficiency.
