Detailed Implementation

[0025] The present invention will be further described in detail below with reference to specific embodiments, so that those skilled in the art can more clearly understand the present invention.

[0026] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed structures. Those skilled in the art can understand the specific meaning of these terms in this patent based on the specific circumstances.

[0027] Example 1

[0028] This embodiment provides an auxiliary assembly device for steering steel tubes and connectors in commercial vehicles, comprising:

[0029] Base 1,

[0030] For example, see Figure 1-2 The top of base 1 is a flat structure, and the top of base 1 can be used to place the hexagonal nut of the connector.

[0031] The lifting mechanism 2 is mounted on the base 1. The lifting mechanism is existing technology, such as a cylinder.

[0032] The fixed V-shaped clamping plate 3 is set on the lifting end of the lifting mechanism 2.

[0033] For example, see Figure 1-2 The fixed V-shaped clamping plate 3 has a V-shaped cross-section, with its opening facing left. The fixed V-shaped clamping plate 3 is adapted to fit the hexagonal nut; that is, the two plates of the fixed V-shaped clamping plate 3 are parallel to the adjacent sides of the hexagonal nut, allowing the fixed V-shaped clamping plate 3 to fit snugly against the sidewall of the hexagonal nut. Furthermore, since the included angle of the hexagonal nut is fixed, meaning that different models of hexagonal nuts have the same included angle, the fixed V-shaped clamping plate 3 can fit snugly against the sidewall of any model of hexagonal nut.

[0034] Mounting plate 4 is mounted on the lifting end of lifting mechanism 2. A first screw hole is provided through the mounting plate 4, and a first screw rod 5 is screwed into the first screw hole. One end of the first screw rod 5 is rotatably connected to a pressing plate 6. A first sliding hole is provided through the mounting plate 4, and a first sliding rod 7 is slidably sleeved in the first sliding hole. The first sliding rod 7 is fixed to the pressing plate 6. A movable V-shaped clamping plate 8 is provided on the pressing plate 6, and the movable V-shaped clamping plate 8 is arranged opposite to the fixed V-shaped clamping plate 3.

[0035] For example, see Figure 1-3 The mounting plate 4 is vertically positioned, with a first screw hole and a first sliding hole extending through it on both sides. The first sliding hole is located below the first screw hole. A pressing plate 6 is rotatably connected to the right end of the first screw rod 5, and the right end of the first sliding rod 7 is fixed to the pressing plate 6. Thus, when the first screw rod 5 rotates, the pressing plate 6 can only move left and right due to the limiting effect of the first sliding rod 7. That is, the position of the pressing plate 6 can be adjusted by rotating the first screw rod 5. A movable V-shaped clamping plate 8 is fixed on the right side wall of the pressing plate 6. The opening of the movable V-shaped clamping plate 8 faces to the right, and the movable V-shaped clamping plate 8 is at the same horizontal height as the fixed V-shaped clamping plate 3, that is, the movable V-shaped clamping plate 8 is aligned with the fixed V-shaped clamping plate 3.

[0036] For hexagonal nuts of different sizes, the horizontal height of the movable V-shaped clamping plate 8 and the fixed V-shaped clamping plate 3 can be adjusted synchronously by moving the lifting end of the lifting mechanism 2 up and down, so that the center line of the V-shaped clamping plate is at the same horizontal height as the center line of the hexagonal nut, and the V-shaped clamping plate can fit into the hexagonal nut.

[0037] Based on the above structure, the hexagonal nut of the connector is placed on the base 1. The lifting mechanism 2 moves its lifting end up and down, causing the movable V-shaped clamping plate 8 and the fixed V-shaped clamping plate 3 to be positioned on either side of the hexagonal nut. Then, by rotating the first screw 5, the position of the pressing plate 6 is adjusted, thereby adjusting the position of the movable V-shaped clamping plate 8, which gradually moves closer to the fixed V-shaped clamping plate 3, thus clamping and fixing the hexagonal nut. This provides high stability and prevents the hexagonal nut from shifting or sliding on the base 1 during tightening. Combined with the lifting mechanism 2, it can clamp and fix hexagonal nuts of different sizes and models, offering wide applicability and high stability, representing a significant advancement in the development of nut clamping devices.

[0038] In this embodiment, a rubber pad layer may be provided on the inner side of the movable V-shaped clamping plate 8, which can improve the friction between the movable V-shaped clamping plate 8 and the hexagonal nut.

[0039] Similarly, a rubber pad can be provided on the inner side of the fixed V-shaped clamping plate 3 to increase the friction between the fixed V-shaped clamping plate 3 and the hexagonal nut.

[0040] To facilitate the rotation of the first screw 5 by the staff, a rotating disc is coaxially fixed to the end of the first screw 5 away from the pressing plate 6.

[0041] For example, see Figure 1-3 A rotating disk is coaxially fixed to the left end of the first screw 5, which makes it convenient for staff to manually rotate the first screw 5.

[0042] Example 2

[0043] Based on embodiment 1, the lifting mechanism 2 may include a second screw 201, a second sliding rod 202, a lifting platform 203, and a rotating platform 204. The lifting platform 203 is provided with a second screw hole, the rotating platform 204 is mounted on the base 1, the second screw 201 is rotatably connected to the rotating platform 204, the second screw 201 is screwed to the second screw hole, the lifting platform 203 is provided with a second sliding hole, the second sliding rod 202 is fixed on the base 1, and the second sliding rod 202 is slidably sleeved in the second sliding hole.

[0044] For example, see Figure 2 The lifting platform 203 has a second screw hole and a second sliding hole running vertically through it. A rotating platform 204 is fixed to the top of the base 1. A second screw 201 is vertically arranged and screwed into the second screw hole. The bottom end of the second screw 201 is rotatably connected to the rotating platform 204. A second sliding rod 202 is vertically arranged and slidably fitted into the second sliding hole. The bottom end of the second sliding rod 202 is fixed to the base 1. Thus, when the second screw 201 rotates, the lifting platform 203 can only move up and down due to the limiting effect of the second sliding rod 202; that is, the position of the lifting platform 203 can be adjusted by rotating the second screw 201. The lifting platform 203 is the lifting end of the lifting mechanism 2. A fixed V-shaped clamping plate 3 is fixed below the lifting platform 203, and a mounting plate 4 is also fixed below the lifting platform 203.

[0045] To facilitate the rotation of the second screw 201 by the staff, a rotating disk is coaxially fixed to the end of the second screw 201 away from the rotating table 204.

[0046] For example, see Figure 2 The top of the second screw 201 is coaxially fixed with a rotating disk, which makes it convenient for staff to manually rotate the second screw 201.

[0047] Example 3

[0048] Based on Embodiment 1, the auxiliary assembly device for commercial vehicle steering steel pipe and connector provided in this embodiment also includes a clamping structure 9, with the base 1 fixed on the clamping structure 9, and the clamping structure 9 is a C-shaped structure.

[0049] For example, see Figure 5 The clamping structure 9 can be clamped onto the workbench 13 to fix the base 1.

[0050] The clamping structure 9 includes a top plate, a bottom plate, and a vertical plate. The top plate and the bottom plate are fixedly connected by the vertical plate. Two third screw holes are provided through the bottom plate, and a third screw 10 is screwed into the third screw holes.

[0051] For example, see Figure 1 , Figure 5 The top plate is placed above the workbench 13 and the bottom plate is placed below the workbench 13. Then, by rotating the third screw 10, the top of the third screw 10 abuts against the workbench 13, thus clamping and fixing the clamping structure 9 onto the workbench 13. The operation is simple and the installation is convenient.

[0052] Among them, the inner end of the third screw 10 is provided with a pressure block 11.

[0053] For example, see Figure 1 , Figure 4 The top of the third screw 10 is provided with a pressure block 11, which can be a rubber pressure block, to increase the friction between the top of the third screw 10 and the worktable 13.

[0054] The third screw 10 has a rotating handle 12 at its outer end.

[0055] For example, see Figure 1 , Figure 4 The third screw 10 is equipped with a rotating handle 12 at its bottom end, which makes it convenient for staff to manually rotate the third screw 10, making the operation easier.

[0056] The mechanisms, components, and parts in this invention that are not specifically described are all existing structures in the prior art and can be purchased directly from the market.
