[0061] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0062] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment discloses a steering rack marking and positioning device, which includes a support frame 1, a feeding adjustment component 2, a drive correction mechanism 3, and an auxiliary positioning mechanism 4. The support frame 1 has a receiving space for accommodating the steering rack. The feeding adjustment component 2 is disposed at the front end of the support frame 1 and extends into the receiving space. The feeding adjustment component 2 is used to push the steering rack in the receiving space toward the rear end of the support frame 1. The drive correction mechanism 3 and the auxiliary positioning mechanism 4 are respectively disposed on both sides of the rear end of the support frame 1. The auxiliary positioning mechanism 4 moves in a direction close to the drive correction mechanism 3 so that the auxiliary positioning mechanism 4 and the drive correction mechanism 3 are respectively used to clamp and position the two ends of the steering rack. The drive correction mechanism 3 is used to drive the rotational movement of the steering rack.

[0063] The steering rack is placed within the receiving space of the support frame 1. The feeding adjustment component 2 pushes the steering racks placed within the support frame 1 backward, facilitating individual feeding of each rack. Simultaneously, when the steering rack needs positioning, the auxiliary positioning mechanism 4 moves towards the drive correction mechanism 3. The auxiliary positioning mechanism 4 pushes the steering rack, and with the cooperation of the drive correction mechanism 3, effectively clamps and fixes the steering rack. The drive correction mechanism 3 drives the rotational movement of the steering rack, facilitating coaxial rotation and adjustment, ensuring stable positioning and improving coding accuracy. Furthermore, the precise positioning of the steering rack is achieved through the drive correction mechanism 3 and the auxiliary positioning mechanism 4, eliminating the need for manual intervention and significantly improving the coding efficiency of the steering rack coding and positioning device.

[0064] The support frame 1 includes a U-shaped mounting bracket 11, a mounting base 12, and a support frame 13. The accommodating space is located within the U-shaped mounting bracket 11. The bottom of the support frame 13 is connected to the U-shaped mounting bracket 11, and the top of the support frame 13 supports the steering racks. The mounting base 12 is connected to the front end of the U-shaped mounting bracket 11. The feeding adjustment component 2 is mounted on the mounting base 12 and extends into the U-shaped mounting bracket 11. The drive correction mechanism 3 and the auxiliary positioning mechanism 4 are respectively located on both sides of the rear end of the U-shaped mounting bracket 11. The support frame 13 is located within the accommodating space and is mounted and connected to the bottom surface of the U-shaped mounting bracket 11. Multiple steering racks are placed within the accommodating space and located on the support frame 13. The feeding adjustment component 2 is used to push the steering racks. The auxiliary positioning mechanism 4 cooperates with the drive correction mechanism 3 for positioning and rotational correction of the steering racks.

[0065] In this embodiment, the U-shaped mounting bracket 11 includes a base plate and two side plates, with the two side plates connected to both ends of the base plate to form a U-shape. The mounting base 12 is plate-shaped. The support frame 13 is plate-shaped. The overall structure of the support frame 1 is simple and easy to manufacture.

[0066] There are two support frames 13, which are placed parallel to each other and located on both sides of the U-shaped mounting bracket 11. The two support frames 13 are parallel to the two side plates and adjacent to the two side plates respectively. The bottom of the two support frames 13 is connected to the base plate, and the two ends of the steering rack are placed on the top of the two support frames 13 respectively, so as to effectively support the multiple steering racks.

[0067] In this embodiment, the top of the support frame 13 has a plurality of placement slots 131 for placing steering racks, and the plurality of placement slots 131 are spaced apart along the length direction of the support frame 13. Specifically, the plurality of placement slots 131 are equidistantly spaced on the top of the support frame 13 in the front-rear direction, and multiple steering racks are placed in the plurality of placement slots 131 respectively to achieve stable support for the steering racks.

[0068] The feeding adjustment assembly 2 includes a horizontal pushing mechanism 21, a push plate 22, a vertical lifting mechanism 23, and a support shell 24. The push plate 22, the vertical lifting mechanism 23, and the support shell 24 are all located inside the U-shaped mounting bracket 11. The fixed end of the horizontal pushing mechanism 21 is connected to the mounting base 12, and the movable end of the horizontal pushing mechanism 21 is connected to the push plate 22 and is used to drive the push plate 22 to move toward the rear end of the U-shaped mounting bracket 11. The bottom of the vertical lifting mechanism 23 is connected to the push plate 22, and the top of the vertical lifting mechanism 23 is connected to the support shell 24 and is used to drive the support shell 24 to move upward so that the support shell 24 can support the steering rack. The steering rack is placed in the placement slot 131 at the top of the support frame 13. When the feeding adjustment assembly 2 is in use, the vertical lifting mechanism 23 provides driving force to drive the support shell 24 to move upward, so that the support shell 24 lifts the steering rack placed in the placement slot 131 and removes it from the placement slot 131. Then, the horizontal pushing mechanism 21 provides driving force to drive the push plate 22 to move backward, so that the lifted steering rack moves between the drive correction mechanism 3 and the auxiliary positioning mechanism 4. The auxiliary positioning mechanism 4 cooperates with the drive correction mechanism 3 to position and rotate the steering rack, thereby improving the coding accuracy.

[0069] In this embodiment, there are two horizontal pushing mechanisms 21 and two pushing plates 22. The two pushing plates 22 are placed in parallel and located on both sides of the U-shaped mounting bracket 11. The two pushing plates 22 are arranged parallel to the two support brackets 13 and the two side plates. The two pushing plates 22 are located between the two support brackets 13 and are adjacent to the two support brackets 13 respectively, so that the support shells 24 on the two pushing plates 22 are used to support and lift the two ends of the steering rack, thereby improving the stability of lifting the steering rack.

[0070] There are multiple vertical lifting mechanisms 23 and multiple support shells 24, each corresponding to the other. The multiple vertical lifting mechanisms 23 are spaced apart along the length of the push plate 22. Specifically, the multiple vertical lifting mechanisms 23 and multiple support shells 24 are equidistantly spaced on the top of the push plate 22 in the front-back direction, and the multiple support shells 24 provide stable support for the multiple steering racks.

[0071] The support shell 24 is made of rubber, which is easy to process and manufacture, and has low cost. The side cross-section of the support shell 24 is U-shaped, and the U-shaped opening of the support shell 24 will be used to support and lift the steering rack, further ensuring stable support and lifting of the steering rack.

[0072] The horizontal pushing mechanism 21 can be a cylinder, with the cylinder housing fixed on the mounting base 12. The cylinder's drive rod passes through the mounting base 12 and is connected to the push plate 22. The vertical lifting mechanism 23 can be a hydraulic cylinder. The top of the push plate 22 has multiple inwardly recessed mounting grooves. The hydraulic cylinder is installed in the mounting grooves, and the hydraulic cylinder's drive rod is connected to the bottom of the support shell 24.

[0073] The feeding adjustment assembly 2 also includes a guide seat 25 and a guide rail 26. The bottom of the guide seat 25 is connected to the U-shaped mounting bracket 11, and the top of the guide seat 25 has a guide groove. The guide rail 26 is connected to the bottom of the push plate 22 and is slidably disposed within the guide groove. The guide seat 25 and the guide rail 26 have a sliding guiding function. The guide seat 25 is located within the accommodating space of the U-shaped mounting bracket 11 and is connected to the base plate. The guide groove extends in the front-back direction at the top of the guide seat 25, and the guide rail 26 can move in the front-back direction within the guide groove, thereby driving the push plate 22, multiple vertical lifting mechanisms 23, and multiple support shells 24 to move in the front-back direction. This results in high stability of the steering rack moving backward, effectively avoiding offset and misalignment, further ensuring the stable positioning of the steering rack, thereby improving the coding accuracy and greatly improving the coding efficiency of the steering rack coding and positioning device.

[0074] The drive correction mechanism 3 includes a drive motor 31 and a first positioning head 32. The drive motor 31 is mounted on the rear end of the support frame 1. One end of the first positioning head 32 is connected to the drive motor 31, and the other end of the first positioning head 32 abuts against the steering rack. The drive motor 31 drives the first positioning head 32 to rotate, thereby causing the steering rack to rotate as well. The first positioning head 32 abuts against the end of the steering rack. The drive motor 31 provides driving force and drives the first positioning head 32 to rotate, thereby causing the steering rack to rotate as well. This facilitates the rotation of the steering rack, makes it easier to mark the corresponding position, ensures the stable positioning of the steering rack, and improves the accuracy of the marking. The first positioning head 32 is conical in shape, and its tip is inserted into the steering rack to achieve stable positioning of the steering rack.

[0075] The drive correction mechanism 3 also includes a first limiting seat 33 and a mounting shell 34. One end of the first limiting seat 33 is connected to the outer side of the support frame 1, and the other end of the first limiting seat 33 extends outward. The mounting shell 34 is connected to the first limiting seat 33, and the drive motor 31 is disposed inside the mounting shell 34. The first limiting seat 33 is installed on the outer side of the side plate of the support frame 1, and the mounting shell 34 is installed and connected to the first limiting seat 33. The first limiting seat 33 ensures that the overall structure of the drive correction mechanism 3 is stably and reliably connected, ensuring that the drive correction mechanism 3 stably drives the steering rack to rotate, improving the coding accuracy, and greatly improving the coding efficiency of the steering rack coding positioning device. The drive motor 31 is disposed inside the mounting shell 34, which protects the drive motor 31, ensuring the stability and reliability of the drive motor 31 and extending the service life of the drive correction mechanism 3. The outer edge of the bottom end of the mounting shell 34 is threadedly connected to the top surface of the first limiting seat 33 by connecting bolts, making installation and connection convenient.

[0076] The drive correction mechanism 3 also includes a drive shaft 35, with its two ends connected to the drive end of the drive motor 31 and the first positioning head 32, respectively. The drive motor 31 is installed inside the mounting housing 34, with its drive end extending outward and connected to the drive shaft 35. The drive shaft 35 transmits rotational driving force to the first positioning head 32, thereby driving the rotation of the first positioning head 32 and the steering rack.

[0077] The auxiliary positioning mechanism 4 includes a pushing component 41 and a second positioning head 42. The pushing component 41 is mounted on the rear end of the support frame 1. One end of the second positioning head 42 is connected to the pushing component 41. The pushing component 41 pushes the second positioning head 42 to move in a direction closer to the drive correction mechanism 3, so that the other end of the second positioning head 42 abuts against the steering rack. The pushing component 41 provides driving force and drives the second positioning head 42 to move in a direction closer to the drive correction mechanism 3, thereby pushing the steering rack to move in a direction closer to the drive correction mechanism 3. The second positioning head 42 and the first positioning head 32 abut against the two ends of the steering rack, thereby effectively clamping and fixing the steering rack for subsequent coding. The second positioning head 42 is conical in shape, and its tip is inserted into the steering rack to achieve stable positioning of the steering rack.

[0078] The auxiliary positioning mechanism 4 also includes a movable seat 43 and a rotating shaft 44. The movable seat 43 is connected to the drive end of the pushing component 41, and one end of the rotating shaft 44 is rotatably connected to the movable seat 43, while the other end of the rotating shaft 44 is connected to the second positioning head 42. The pushing component 41 provides driving force to move the pushing component 41 in a direction close to the driving correction mechanism 3, and drives the rotating shaft 44 and the second positioning head 42 to move, so that the second positioning head 42 and the first positioning head 32 respectively abut against the two ends of the steering rack. Then, the driving correction mechanism 3 drives the steering rack to rotate, and through the rotating shaft 44, it is rotatably connected to the movable seat 43, so that the second positioning head 42 and the rotating shaft 44 also rotate together, while the movable seat 43 and the pushing component 41 do not need to rotate, ensuring the coding operation of the steering rack and improving the coding accuracy.

[0079] The movable seat 43 has a rotating groove 431 on the side away from the pushing component 41, and the rotating shaft 44 has a rotating block 441 at the end away from the second positioning head 42. The rotating block 441 is located in the rotating groove 431 and can rotate within it. The rotating block 441 protrudes radially outward and is confined within the rotating groove 431 to prevent it from detaching. The rotating groove 431 has a large internal space and narrows inward at its opening, ensuring that the rotating block 441 is positioned within the rotating groove 431 and will not detach, thus guaranteeing stable rotation within the rotating groove 431.

[0080] The auxiliary positioning mechanism 4 also includes a second limiting seat 45. One end of the second limiting seat 45 is connected to the outer side of the support frame 1, and the other end of the second limiting seat 45 extends outward. The pushing component 41 is connected to the second limiting seat 45. The second limiting seat 45 is installed on the outer side of the side plate of the support frame 1. The pushing component 41 and the moving seat 43 are both installed and connected to the second limiting seat 45. The second limiting seat 45 ensures that the overall structure of the auxiliary positioning mechanism 4 is installed and connected stably and reliably, ensuring that the auxiliary positioning mechanism 4 stably drives the steering rack to move and rotate, improving the coding accuracy and greatly improving the coding efficiency of the steering rack coding positioning device.

[0081] The movable seat 43 is slidably connected to the second limiting seat 45. A guide rail and a sliding groove can be provided between the movable seat 43 and the second limiting seat 45 to make the movement more stable and reliable.

[0082] The pushing component 41 can be an electric push rod. When the electric push rod is activated, it pushes the fixedly connected movable seat 43 to move. The movable seat 43 pushes the rotatably connected rotating shaft 44 to move. The rotating shaft 44 pushes the second positioning head 42 to move. Under the action of the subsequent drive correction mechanism 3, the steering rack can be clamped and placed, which is convenient for subsequent coding.

[0083] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.
