[0026] The steering gear centering and positioning installation device of this utility model mainly includes a base 1, a slide rail 2, a slider 3, a fixed frame 4, a centering detection module 5, and a drive unit 6. These components, through specific connection relationships and positional layout, jointly achieve precise centering and efficient installation of the steering gear in three-dimensional space. The specific embodiments of this utility model are described in detail below with reference to the specific drawings and the component numbers marked in the drawings.

[0027] like Figure 1 As shown, the base 1 serves as the fundamental support structure for the entire device. At least two sets of slide rails 2 are mounted on its top, arranged parallel to the horizontal direction of the base 1. Each set of slide rails 2 has a sliding block 3 slidably mounted on it. The sliding block 3 achieves linear movement guided by the slide rails 2. A high-precision ball bearing guide pair is used between the slide rails 2 and the sliding block 3 to ensure smooth sliding of the sliding block 3 on the slide rails 2 without significant gaps. The bottom of the sliding block 3 has a groove containing embedded balls. The balls contact and roll with the track surface of the slide rail 2, thereby reducing friction and improving the accuracy and efficiency of the sliding block 3's movement. Limit blocks are provided at both ends of the slide rails 2 to prevent the sliding block 3 from dislodging from the slide rails 2, and these limit blocks also protect the slide rails 2 and the sliding block 3.

[0028] An adjustment assembly is mounted on the top of slider 3, which includes a rotary table 7, a lifting column 8, and a clamping mechanism 9. For example... Figure 2As shown, the rotating table 7 is fixedly installed on the top of the sliding block 3 by bolts, which pass through the bottom plate of the rotating table 7 and are connected with the threaded holes on the top of the sliding block 3. A group of threaded holes are arranged on the top of the rotating table 7 for installing the lifting column 8. The lifting column 8 is connected with the rotating table 7 by threads, and the outer surface of the lifting column 8 is provided with scale marks for indicating the lifting height. The top of the lifting column 8 is hingedly connected with a group of clamping mechanisms 9 through a pin shaft. The clamping mechanism 9 is composed of two groups of clamping plates, and rubber pads are attached to the inner side surfaces of the clamping plates. The thickness of the rubber pads is 2-5 mm, which can avoid damaging the surface of the direction machine when clamping. The clamping plates are connected by springs, one end of the spring is welded to the outer side surface of one group of clamping plates, and the other end is welded to the outer side surface of the other group of clamping plates. Handles are welded to the outer side surfaces of the clamping plates, which are arc-shaped to facilitate manual adjustment of the opening angle of the clamping plates by the operator. By rotating the handle manually, the opening distance between the clamping plates can be adjusted to adapt to direction machines of different sizes.

[0029] The fixed frame 4 is arranged on the top of the base 1, and the bottom of the fixed frame 4 is connected with the base 1 by bolts. A plurality of support rods are connected with the inside of the fixed frame 4 by bolts, and the top of the support rod is fixedly welded to the inner wall of the fixed frame 4. At least two groups of mounting holes are arranged on the top of the fixed frame 4, and bearings are embeddedly installed in the mounting holes. The inner ring of the bearing is in interference fit with the transmission shaft 10. Figure 3 As shown, one end of the transmission shaft 10 is connected with the output end of the driving unit 6 through a shaft coupling, and the other end is connected with a gear 11 through a key groove. The gear 11 is engaged with a rack 12 on the slide rail 2, and the rack 12 is arranged along the length direction of the slide rail 2 and is fixed to the side surface of the slide rail 2 by bolts. When the driving unit 6 is started, the transmission shaft 10 rotates and drives the sliding block 3 to move along the slide rail 2 through the meshing action of the gear 11 and the rack 12, thereby realizing the position adjustment of the direction machine in the X-axis and Y-axis directions.

[0030] The centering detection module 5 is arranged on the top of the fixed frame 4, as shown in the figure. Figure 4 The centering detection module 5 includes a laser range finder and an angle sensor. The emitting end of the laser range finder is directed to the mounting position of the direction machine, which is used to measure the distance deviation between the direction machine and the target position in real time. The angle sensor is installed on one side of the laser range finder, which is used to detect the angle deviation of the direction machine. The centering detection module 5 also includes a display screen and a controller. The display screen is fixedly installed on the outer surface of one side of the fixed frame 4 by screws, which is used to display the position deviation data of the direction machine. The controller is electrically connected with the laser range finder and the angle sensor through wires. The controller receives the detection signals and generates control instructions, which are transmitted to the driving unit 6, thereby realizing automatic centering adjustment. An observation window 16 is arranged on the front outer surface of the fixed frame 4, and a transparent glass plate is embeddedly installed in the observation window 16. The transparent glass plate is tightly attached to the inner wall of the fixed frame 4 by sealing rubber strips around the transparent glass plate, which is used to observe the mounting state of the direction machine in real time.

[0031] like Figure 5 As shown, the base 1 has at least four sets of casters 13 at its bottom, each set of casters 13 being bolted to the bottom of the base 1. A brake pedal 14 is located on top of each caster 13, and the brake pedal 14 is connected to the locking device of the caster 13 via a lever mechanism. When the brake pedal 14 is pressed, the lever mechanism pushes the locking device to engage the axle of the caster 13, thereby locking the position of the caster 13. At least two sets of drainage channels 15 are provided on the top of the base 1. The bottom of the drainage channels 15 is connected to an external drainage system via pipes to drain any water that may accumulate during equipment operation. The drainage channels 15 are 10 mm to 20 mm wide and 5 mm to 10 mm deep, effectively preventing water accumulation and its impact on equipment operation.

[0032] In practical applications, the operator first places the steering gear between the clamping plates of the clamping mechanism 9 and manually adjusts the handle to clamp the steering gear. Then, the drive unit 6 is activated. The drive unit 6 drives the gear 11 to rotate via the transmission shaft 10. The meshing action of the gear 11 and rack 12 pushes the slider 3 along the slide rail 2, thus achieving initial position adjustment of the steering gear in the X and Y axes. During the adjustment process, the laser rangefinder and angle sensor of the centering detection module 5 collect the position deviation data of the steering gear in real time and transmit the data to the controller. The controller generates control commands based on the collected data and transmits the control commands to the drive unit 6. The drive unit 6 adjusts the moving speed and direction of the slider 3 according to the control commands, thereby achieving precise centering of the steering gear. During the centering process, the operator can observe the installation status of the steering gear in real time through the observation window 16 and make fine adjustments by adjusting the rotary table 7 and the lifting column 8 in the adjustment assembly to ensure that the height and angle of the steering gear meet the installation requirements.

[0033] When the equipment needs to be moved, the operator can push the equipment to the target position using the casters 13 and press the brake pedal 14 to lock the position of the casters 13, ensuring the equipment remains stable during installation. If water accumulates during equipment operation, the water will be drained into the external drainage system through the drain trough 15 to avoid affecting the normal operation of the equipment.

[0034] This invention achieves efficient centering and precise installation of the steering gear in three-dimensional space through the rational layout and precise coordination of the aforementioned components. All components of the device work collaboratively through clearly defined connection and positional relationships, ensuring ease of operation and accuracy of installation.

[0035] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0036] When installing the direction machine, first place the direction machine to be installed between the two sets of clamping plates of the clamping mechanism 9. Adjust the opening angle of the clamping plates by manually rotating the handle, so that the clamping plates can tightly clamp the direction machine. The rubber pads attached to the inner side of the clamping plates can prevent damage to the surface of the direction machine during clamping, and the design of the spring ensures that the clamping plates have a certain elastic buffering capacity when clamping, thereby adapting to direction machines of different sizes. After clamping is completed, the operator starts the drive unit 6, and the output end of the drive unit 6 drives the transmission shaft 10 to rotate through the shaft coupling. One end of the transmission shaft 10 is connected with a gear 11 through a key groove, and the gear 11 is engaged with a rack 12 on the slide rail 2. Under the drive of the transmission shaft 10, the gear 11 pushes the rack 12 to move, thereby making the sliding block 3 slide smoothly along the slide rail 2. This process realizes the preliminary position adjustment of the direction machine in the X and Y axis directions.

[0037] During the movement of the sliding block 3, the laser range finder in the centering detection module 5 measures the distance deviation between the direction machine and the target installation position in real time, and transmits the data to the controller. At the same time, the angle sensor detects the angle deviation of the direction machine and synchronously transmits the signal to the controller. The controller generates control instructions according to the received data and transmits the instructions to the drive unit 6. The drive unit 6 adjusts the rotation speed and direction of the transmission shaft 10 according to the control instructions, thereby accurately controlling the movement speed and direction of the sliding block 3, ensuring that the direction machine gradually approaches the target installation position. In this process, the display screen displays the position deviation data of the direction machine in real time, facilitating the operator to monitor the installation state. Through the observation window 16, the operator can intuitively observe the installation of the direction machine, especially in a narrow space, the design of the observation window 16 significantly improves the convenience of operation.

[0038] When the direction machine approaches the target position in the X and Y axis directions, the operator can fine-tune it by adjusting the rotating table 7 and the lifting column 8 in the adjusting assembly. The rotating table 7 is fixedly installed on the top of the sliding block 3 by bolts, and its top is provided with a threaded hole for installing the lifting column 8. The outer surface of the lifting column 8 is marked with height marks, and the operator can adjust the height of the lifting column 8 according to the marks, thereby realizing the accurate positioning of the direction machine in the Z axis direction. The design of the rotating table 7 allows the operator to fine-tune the angle of the direction machine to ensure that the posture of the direction machine meets the installation requirements. Through the above steps, the accurate centering of the direction machine in the three-dimensional space is realized.

[0039] In addition, the base 1 of the equipment is equipped with multiple sets of casters 13, allowing operators to flexibly move the equipment to the target location. Once the equipment reaches the designated position, pressing the brake pedal 14 activates a lever mechanism that engages a locking device to engage the axles of the casters 13, thus locking the equipment in place and ensuring stability during installation. If water accumulates during operation, it will drain through a drainage channel 15 on the top of the base 1 to the external drainage system, preventing any impact on normal operation. The drainage channel 15 is designed to be 10 mm to 20 mm wide and 5 mm to 10 mm deep, effectively preventing water accumulation and demonstrating the equipment's reliability and durability in practical use.

[0040] In summary, this invention achieves efficient centering and precise installation of the steering gear in three-dimensional space through the high-precision cooperation between the slide rail 2 and the slider 3, the meshing of the gear 11 and the rack 12, the real-time monitoring of the centering detection module 5, and the flexible adjustment of the adjustment components. The coordinated operation of all components ensures ease of operation and accuracy of installation, significantly improving the efficiency and reliability of steering gear installation.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
