Description

Technical Field

[0001] This utility model relates to an internal azimuth axis electrical control device, specifically belonging to the field of electrical control technology. Background Technology

[0002] With the continuous improvement of industrial automation, the requirements for automated control, precision and safety of equipment are also getting higher and higher; traditional manual control methods can no longer meet the needs of modern production. Therefore, electronic control devices have gradually become an important part of automated production.

[0003] Currently, some telescopes still rely on manual rotation of the azimuth axis. As the azimuth axis is an important component of mechanical equipment, its control method directly affects the performance and efficiency of the equipment. Traditional manual control methods for the azimuth axis have problems such as cumbersome operation, insufficient precision, and low safety, which limit the application range and efficiency of the equipment.

[0004] Existing manual rotating axes operate continuously year-round, which is time-consuming and labor-intensive. The azimuth axis operation of some telescopes is cumbersome and requires manual intervention, resulting in low efficiency and operator fatigue due to prolonged working hours. Furthermore, manual operation struggles to guarantee precise azimuth axis positioning, impacting equipment accuracy and efficiency. Finally, manual operation poses safety hazards, especially in harsh environments, increasing the risk of accidents. Utility Model Content

[0005] The purpose of this invention is to provide an internal azimuth axis electrical control device to solve the problems of time-consuming and laborious manual operation, inaccurate position accuracy, and cumbersome and complicated operation of existing telescope azimuth axes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: the new model includes a fixing frame and a base, and also includes a grating probe and a driving assembly;

[0007] A hinge is fixedly connected to one end of the base, and a fixed frame is connected to the base through the hinge. The fixed frame is an external support mechanism. A grating probe is fixedly installed on the base by a nut. A pin hole is opened on one side of the base, and a drive component is set on the front side of the base.

[0008] Furthermore, one end of the base is connected to the fixing frame, and the other end of the base is connected to the fixing frame through a pin mechanism, thereby completing the installation of the base. The drive component drives the grating probe to adjust its position, and then the grating probe feeds back the real-time position signal to the computer.

[0009] The drive components include a motor, a gear ring, gears, and a coupling;

[0010] The base is fixedly connected to a motor by bolts, the motor output shaft is fixedly connected to a coupling, the motor is fixedly connected to a gear by the coupling, and a gear ring is meshed with one end of the gear;

[0011] Furthermore, by using servo motors, precise control of the azimuth axis is ensured, thereby improving the equipment's accuracy.

[0012] The drive assembly also includes a compression spring and a pin;

[0013] A pin is fixedly connected to one side of the fixed frame, a compression spring is sleeved on the outside of the pin, and a pin hole is inserted into the other end of the pin.

[0014] Furthermore, by setting a compression spring, the gear and gear ring can be adjusted to the most suitable position before being clamped, in order to adapt to vibration changes, length errors, and manufacturing and installation errors during transmission.

[0015] It also includes handles;

[0016] A handle is fixedly connected to the front side of the base, and the height of the handle is greater than the thickness of the base;

[0017] Furthermore, when the equipment stops operating or is being maintained, the gear can be disengaged from the gear ring by lifting the handle.

[0018] The beneficial effects of this utility model are:

[0019] 1. The azimuth axis is precisely controlled by a servo motor, improving the equipment's accuracy. The azimuth axis is automatically controlled by an electronic control system. The gear can be disengaged from the gear ring via a handle, facilitating equipment maintenance and repair.

[0020] 2. The handle and compression spring are designed to allow the handle to move the base, which in turn allows the pin hole and pin shaft to engage and compress the compression spring. This allows the gear and gear ring to be adjusted to the most suitable position and then tightened, thus adapting to vibration changes, length errors, and manufacturing and installation errors during transmission. This effectively reduces safety risks, ensures personnel safety, avoids safety hazards associated with manual control, and reduces the possibility of operational errors.

[0021] 3. By setting damping material layers at gear meshing points, shock-absorbing sleeves at hinge shafts, and shock-absorbing pads at motor connection points, the vibration reduction function is effectively achieved, reducing the impact of vibration on equipment operation, improving equipment stability and reliability, and reducing equipment failures and safety hazards caused by vibration.

[0025] The following will be combined with the appendix Figure 1-2 The technical solutions in the embodiments are described clearly and completely.

[0026] Specific implementation method one: as follows Figure 1 As shown, the fixed frame 1 is an external support mechanism, therefore, its function is to provide a stable support foundation for the entire device. During the operation of the device, the fixed frame 1 remains stationary and does not move. One end of the fixed frame 1 is hinged to the base 2 via a hinge pin 4, allowing the base 2 to rotate around the hinge pin 4 as the axis, providing a rotational basis for adjusting the azimuth axis. Since the grating probe 7 is fixedly installed on the base 2 by a nut, a grating ruler is provided on the device corresponding to the grating probe 7. The grating ruler is usually fixedly installed at a suitable position related to the movement of the azimuth axis, for example, it can be fixed on the fixed frame 1 and along the movement path of the base 2. Correspondingly, the grating probe 7 is fixedly mounted on the base 2 by a nut. The grating probe 7 is a high-precision position detection element. Its working principle is to utilize the optical properties of the grating. When the base 2 moves the grating probe 7 relative to the grating ruler, the grating probe 7 scans the grating lines on the grating ruler, converting the mechanical displacement into an electrical signal. After processing, these electrical signals can accurately reflect the real-time position information of the base 2 and feed the position signal back to the computer. After receiving these position signals, the computer can accurately understand the current orientation of the base 2, providing a basis for subsequent orientation adjustment and control.

[0027] A drive assembly is provided on the front side of the base 2. The drive assembly includes a motor 3, a gear ring 9, a gear 10, and a coupling 11. The base 2 is fixedly connected to the motor 3 by bolts. The output shaft of the motor 3 is fixedly connected to the coupling 11. The motor 3 is fixedly connected to the gear 10 through the coupling 11. One end of the gear 10 is meshed with the gear ring 9, thus forming a complete power transmission chain and realizing the effective transmission of power from the motor 3 to the gear ring 9.

[0028] When the computer sends position information to motor 3 for driving, motor 3 transmits power to gear 10 through coupling 11. Since gear 10 is meshed with gear ring 9 at one end, gear 10 can drive gear ring 9 to start rotating. After reaching the designated position, grating probe 7 feeds back the position information to the computer. The computer determines whether the target position has been reached based on the feedback information. If it has, it controls motor 3 to stop running. By using a servo motor for motor 3, which has advantages such as high precision, high response speed and good control performance, it can accurately control the speed and angle according to the computer's instructions, thereby achieving precise adjustment of the azimuth axis. By adopting an electronic control method, automatic control of the azimuth axis is achieved, eliminating the need for manual operation, greatly freeing up manpower and improving work efficiency.

[0029] Specific implementation method two: such as Figure 2 As shown, since a pin 6 is fixedly connected to one side of the fixed frame 1, and a pin hole 12 is provided on one side of the base 2, the pin 6 can be inserted into the pin hole 12, thus forming a movable connection structure. At the same time, a compression spring 5 is sleeved on the outside of the pin 6, and a handle 8 is fixedly connected to the front side of the base 2. When the equipment stops running or is under maintenance, a handle 8 is provided.

[0030] By manually lifting handle 8, handle 8 will rotate around hinge pin 4, causing handle 8 to disengage gear 10 from gear ring 9 via base 2. Simultaneously, base 2, through pin hole 12 and pin pin 6, compresses compression spring 5. After releasing handle 8, the reset action of compression spring 5 will cause gear 10 and gear ring 9 to re-engage tightly. Compression spring 5 can filter vibrations generated during the movement of gear 10 and gear ring 9, as well as errors caused during installation. It can also adapt to vibration changes, length errors, and manufacturing and installation errors during transmission, effectively reducing safety risks, ensuring personnel safety, avoiding safety hazards associated with manual control, and reducing the possibility of operational errors. The entire device uses a touch screen control interface, which is simple, intuitive, and easy to use.

[0031] In order to achieve the shock absorption function, a damping material layer is provided at the meshing point of gear 10 and gear ring 9. The damping material layer can be made of materials with good damping characteristics such as rubber and polyurethane. When gear 10 and gear ring 9 vibrate during the movement, the damping material layer will deform and convert the mechanical energy of the vibration into heat energy to dissipate, thereby playing the role of shock absorption.

[0032] Meanwhile, at the hinge joint between the base 2 and the fixed frame 1, a shock-absorbing sleeve is installed at the hinge shaft 4. The shock-absorbing sleeve is usually made of elastic rubber and other materials. It can buffer the impact and vibration generated between the base 2 and the fixed frame 1 during rotation. When the base 2 rotates, the shock-absorbing sleeve will undergo elastic deformation to absorb and disperse vibration energy, further reducing the impact of vibration on the entire device.

[0033] In addition, a shock-absorbing pad is used at the connection between the motor 3 and the base 2. The shock-absorbing pad can be made of soft rubber or silicone and other materials. The shock-absorbing pad can isolate the vibration generated by the motor 3 when it is running from being transmitted to the base 2. The vibration generated by the motor 3 when it is running will be transmitted to the shock-absorbing pad first. The shock-absorbing pad consumes and disperses the vibration energy through its own elastic deformation, thereby reducing the impact of vibration on the entire transmission system and the accuracy of orientation adjustment.

[0034] The entire device adopts a touch screen control interface, which has the advantages of simple and intuitive operation and ease of use. Operators can easily input orientation adjustment commands and view equipment operating status through the touch screen, which improves the convenience and accuracy of operation.
