Description

Technical Field

[0001] This utility model belongs to the field of sensor tooling technology, and more specifically, it relates to a sensor mounting base with self-calibration function. Background Technology

[0002] A pressure sensor is a device that senses pressure signals and converts them into usable electrical output signals according to a certain rule. Pressure sensors typically consist of a pressure-sensitive element and a signal processing unit. Based on different types of pressure being measured, pressure sensors can be classified into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. Pressure sensors are one of the most commonly used sensors in industrial practice, widely applied in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemicals, oil wells, power, shipbuilding, machine tools, pipelines, and many other industries.

[0003] Based on the above, the following problems were found: When installing existing pressure sensors, they are usually directly fixed to the installation position. After long-term use, the position and angle of the pressure sensor are often shifted due to the influence of pressure. Since the pressure sensor mounting base does not have a calibration function, the pressure sensor is detected in an tilted position, resulting in inaccurate detection results. At the same time, the existing mounting base is usually fixed by drilling holes with screws, which makes installation and disassembly inconvenient.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a sensor mounting base with self-calibration function to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a sensor mounting base with a self-calibration function. This solves the problem that, after prolonged use, the pressure sensor's position and angle often shift due to pressure, causing the sensor to detect in an tilted position, resulting in inaccurate detection results.

[0006] This utility model provides a sensor mounting base with self-calibration function, which is achieved by the following specific technical means:

[0007] A sensor mounting base with self-calibration function includes a base and a mounting base. Threaded sleeves are fixed to both ends of the top of the base. First micro servo motors are hinged to the bottom sides of the mounting base via hinged joints. Second threaded rods are fixed to the power output ends of the two first micro servo motors. The two second threaded rods are threadedly connected to the two threaded sleeves. A push switch is fixed to the top of each of the two first micro servo motors. A connecting shaft is fixed to the middle of the inner wall of the mounting base. A gravity rod is rotatably connected to the middle of the connecting shaft. A pressing block is fixed to the bottom end of the gravity rod. A support rod is fixed to the top of the inner wall of the mounting base. A support block is fixed to the middle of the support rod. A clamping mechanism is provided at the top of the mounting base.

[0008] Furthermore, the push switch is electrically connected to the first micro servo motor, and the push switch is used to detect the pressure of the extrusion block, which is hemispherical in shape.

[0009] Furthermore, grooves are provided on both sides of the middle part of the mounting base, and the two grooves are respectively located directly above the two first micro servo motors, with both ends of the gravity rod penetrating the inside of the grooves.

[0010] Furthermore, the clamping mechanism includes a turntable, which is rotatably connected to the top of the inner wall of the mounting base. A guide rail is fixed to the top of the turntable, and a driven gear is fixed to the bottom of the guide rail. A second micro servo motor is fixed to the inner wall of the mounting base, and a driving gear is fixed to the power output end of the second micro servo motor. The driving gear and the driven gear mesh with each other.

[0011] Furthermore, a sliding rod is slidably connected to the top of the mounting base. Multiple sliding rods are arranged equidistantly in a circle. The end of each sliding rod near the center of the mounting base is arc-shaped. A slider is fixed to the bottom of each sliding rod, and the slider is slidably connected to the guide rail.

[0012] Furthermore, the base is U-shaped, and a first threaded rod is threadedly connected to one side of the base. A knob is fixed to one end of the first threaded rod, and an extrusion plate is rotatably connected to the other end of the first threaded rod.

[0013] Furthermore, the top of the extrusion plate is slidably connected to the top of the inner wall of the base, and triangular grooves are provided on opposite sides of the inner wall of the base and the extrusion plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the gravity rod is fixed to the mounting base by a connecting shaft, so that when the mounting base shifts at an angle, the gravity rod also shifts accordingly, driving the extrusion block to move towards the pressing switch of the first micro servo motor. When the pressing switch is subjected to pressure, the corresponding first micro servo motor rotates, causing the second threaded rod to rotate into the threaded sleeve rod, shortening the gap and keeping the mounting base horizontal, thereby achieving automatic calibration and improving measurement accuracy.

[0016] 2. In this utility model, the sensor is placed on top of the support block, and then the second micro servo motor is controlled to drive the active gear to rotate, which in turn drives the driven gear to rotate, causing the turntable and guide rail to rotate, driving multiple sliders to move horizontally, which in turn drives the top sliding rod to move horizontally. The multiple sliding rods clamp and limit the sensor placed on top of the support block, thereby achieving the effect of being suitable for sensors of various sizes.

[0017] 3. In this utility model, the base is placed in the corresponding installation position, and then the knob is turned to drive the first threaded rod to rotate, so that the extrusion plate fixes the base in the installation position. The multiple triangular grooves increase the contact area between the base and the extrusion plate, making the base more stable after installation. Disassembly can be performed by turning the knob in the opposite direction, thus achieving a convenient installation and disassembly effect. Attached Figure Description

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a sensor mounting base with self-calibration function, including a base 1 and a mounting base 6. Threaded sleeve rods 14 are fixed to both ends of the top of the base 1. First micro servo motors 12 are hinged to the bottom of both sides of the mounting base 6 via hinge seats 10. Second threaded rods 13 are fixed to the power output ends of the two first micro servo motors 12. The two second threaded rods 13 are threadedly connected to the two threaded sleeve rods 14. A push switch 11 is fixed to the top of each of the two first micro servo motors 12. A connecting shaft 7 is fixed to the middle of the inner wall of the mounting base 6. A gravity rod 8 is rotatably connected to the middle of the connecting shaft 7. A pressing block 9 is fixed to the bottom end of the gravity rod 8. A support rod 20 is fixed to the top of the inner wall of the mounting base 6. A support block 21 is fixed to the middle of the support rod 20. A clamping mechanism is provided at the top of the mounting base 6.

[0029] The push switch 11 is electrically connected to the first micro servo motor 12. The push switch 11 is used to detect the pressure of the extrusion block 9. The extrusion block 9 is hemispherical. The gravity rod 8 is fixed to the mounting base 6 through the connecting shaft 7. When the mounting base 6 shifts in angle, the gravity rod 8 also shifts accordingly, causing the extrusion block 9 to move toward the push switch 11 of the first micro servo motor 12. When the push switch 11 is under pressure, the corresponding first micro servo motor 12 rotates, causing the second threaded rod 13 to rotate into the threaded sleeve rod 14, shortening the gap and keeping the mounting base 6 horizontal.

[0030] The mounting base 6 has grooves on both sides of the middle section. The two grooves are located directly above the two first micro servo motors 12. The two ends of the gravity rod 8 pass through the inside of the grooves. The gravity rod 8 is fixed to the mounting base 6 by the connecting shaft 7, so that when the mounting base 6 shifts in angle, the gravity rod 8 also shifts accordingly.

[0031] The clamping mechanism includes a turntable 18, which is rotatably connected to the top of the inner wall of the mounting base 6. A guide rail 19 is fixed to the top of the turntable 18, and a driven gear 17 is fixed to the bottom of the guide rail 19. A second micro servo motor 15 is fixed to the inner wall of the mounting base 6, and a drive gear 16 is fixed to the power output end of the second micro servo motor 15. The drive gear 16 and the driven gear 17 mesh with each other. The second micro servo motor 15 drives the drive gear 16 to rotate, which in turn drives the driven gear 17 to rotate, causing the turntable 18 and the guide rail 19 to rotate. The guide rail 19 is arranged in a horizontal spiral shape.

[0032] The mounting base 6 has a sliding rod 22 slidably connected to its top. Multiple sliding rods 22 are arranged equidistantly in a circle. The end of the sliding rod 22 near the middle of the mounting base 6 is arc-shaped. A slider 23 is fixed to the bottom of the sliding rod 22. The slider 23 is slidably connected to the guide rail 19. By rotating the guide rail 19, the multiple sliders 23 are driven to move horizontally, which in turn drives the top sliding rod 22 to move horizontally. The multiple sliding rods 22 clamp and limit the sensor placed on the top of the support block 22.

[0033] The base 1 is U-shaped, and a first threaded rod 2 is threaded through one side of the base 1. A knob 3 is fixed to one end of the first threaded rod 2, and an extrusion plate 4 is rotatably connected to the other end of the first threaded rod 2. During installation, the base 1 is placed in the corresponding installation position, and then the knob 3 is rotated to drive the first threaded rod 2 to rotate, so that the extrusion plate 4 fixes the base 1 in the installation position.

[0034] The top of the extrusion plate 4 is slidably connected to the top of the inner wall of the base 1. Triangular grooves 5 are provided on the opposite side of the inner wall of the base 1 and the extrusion plate 4. The multiple triangular grooves 5 increase the contact area between the base 1 and the extrusion plate 4, making the base 1 more stable after installation.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In this invention, the base 1 is first placed in the corresponding installation position. Then, the knob 3 is rotated to drive the first threaded rod 2 to rotate, so that the extrusion plate 4 fixes the base 1 in the installation position. The multiple triangular grooves 5 increase the contact area between the base 1 and the extrusion plate 4, making the base 1 more stable after installation. To disassemble, simply rotate the knob 3 in the opposite direction. Next, the sensor is placed on top of the support block 22. Then, the second micro servo motor 15 is controlled to drive the drive gear 16 to rotate, which in turn drives the driven gear 17 to rotate, causing the turntable 18 and the guide rail 19 to rotate, which in turn drives the multiple sliders 23 to move horizontally. This causes the top slide bar 22 to move horizontally. Multiple slide bars 22 clamp and limit the sensor placed on top of the support block 22. The gravity bar 8 is fixed to the mounting base 6 through the connecting shaft 7. When the mounting base 6 shifts in angle, the gravity bar 8 also shifts accordingly, causing the pressing block 9 to move towards the pressing switch 11 of the first micro servo motor 12. When the pressing switch 11 is under pressure, the corresponding first micro servo motor 12 rotates, causing the second threaded rod 13 to rotate into the threaded sleeve rod 14, shortening the gap and keeping the mounting base 6 horizontal, thus achieving the function of automatic calibration.
