Description

Technical Field

[0001] This utility model relates to the technical field of assembly fixtures, and in particular to an assembly fixture for a geomagnetic sensor. Background Technology

[0002] Roadside parking, as a temporary measure, facilitates the needs of users requiring short-term parking, preventing them from spending excessive time entering and exiting parking lots. Besides manual recording, roadside parking fees can also be calculated using geomagnetic sensors to detect whether a vehicle has entered a designated parking space. The geomagnetic sensor detects vehicle information and transmits it to a smart parking system, enabling automatic billing. In actual sensor production, fixtures are needed to hold and secure the sensor before assembly. A sensor processing fixture, as disclosed in prior art publication CN220407921U, includes a fixed base plate on which a first positioning frame is fixedly mounted. Support columns are fixedly mounted on the base plate and on both sides of the first positioning frame. A second positioning frame is positioned above the first positioning frame. A limiting groove is formed within the second positioning frame, and a pressing plate is slidably mounted within the limiting groove. A sliding groove is formed within the second positioning frame, and a threaded column is rotatably mounted within the sliding groove. A pressing slider is threaded onto the threaded column, and a return spring is sleeved on the threaded column. The upper end of the return spring is fixedly connected to the pressing slider, and the lower end of the return spring is fixedly connected to the pressing plate. However, this fixture can only clamp and disassemble multiple sensors simultaneously. Once some sensors are processed, they cannot be disassembled individually; disassembly can only be performed after all multiple sensors have been processed, reducing the practicality of this fixture. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a geomagnetic sensor assembly fixture that can simultaneously clamp or disassemble sensors, or clamp or disassemble sensors individually, thereby improving the usability of the sensor fixture.

[0004] This utility model discloses a geomagnetic sensor assembly fixture, comprising a base, a bottom clamping component, an upper clamping component, a pushing component, and an mounting component. A recessed groove is formed at the top of the base, and the upper clamping component is installed at both the front and rear ends of the base. The pushing component is mounted on the bottom of the base via the mounting component, and its output end is connected to the upper clamping component. Bottom clamping components are installed at both the front and rear ends of the top of the base. Multiple sensor bodies are placed into the recessed groove at the top of the base. The bottom clamping component limits and fixes the lower part of the sensor body, allowing for adjustment of the placement position. The pushing component causes the upper clamping component to clamp the upper side of the sensor body, preventing misalignment during assembly and improving assembly quality. The fixture can simultaneously clamp or disassemble sensors, or clamp or disassemble sensors individually, improving the practicality of the sensor fixture.

[0005] Preferably, the upper clamping component includes multiple sets of fixed seats, multiple sets of rotating shafts, multiple sets of rotating rods, and multiple sets of clamping arms. The multiple sets of fixed seats are symmetrically installed on the front and rear side walls of the base. The rotating shafts rotate on the fixed seats, and rotating rods are installed on the outer walls of the rotating shafts. Clamping arms are installed on the top of the rotating rods. After the sensor is placed on the top of the base, the rotating shafts and rotating rods rotate on the fixed seats, pushing the clamping arms to rotate, so that the two clamping arms come closer to each other to clamp the upper end of the sensor, avoiding misalignment during assembly and improving assembly quality.

[0006] Preferably, the pushing component includes multiple sets of pushing arms, multiple bidirectional telescopic cylinders, and multiple sets of connectors. The pushing arms are installed at the bottom of the rotating rod, the bidirectional telescopic cylinders are located below the base, and connectors are installed at the output ends on the front and rear sides of the bidirectional telescopic cylinders. The connectors are rotatably connected to the pushing arms. When the bidirectional telescopic cylinders are activated, the pushing arms are pushed through the connectors to output power, causing the pushing arms to push the rotating rod to rotate on the fixed seat. The sensor can be clamped or removed individually.

[0007] Preferably, the mounting components include multiple fixing brackets, multiple sets of guide slide rods, multiple mounting seats, and multiple sets of guide sliders. The multiple fixing brackets are installed on the bottom of the base with screws. The fixing brackets have rectangular grooves inside, and guide slide grooves are formed on the left and right sides of the rectangular grooves. The guide slide rods are installed in the guide slide grooves. The mounting seats slide within the rectangular grooves. Guide sliders are installed on the left and right sides of the mounting seats. The guide sliders slide on the outer wall of the guide slide rods and within the guide slide grooves. A bidirectional telescopic cylinder is installed in the middle of the mounting seat. The bidirectional telescopic cylinder is fixed by the mounting seat. When the bidirectional telescopic cylinder pushes the push arm to move, the mounting seat drives the guide sliders to slide on the guide slide rods, avoiding motion interference.

[0008] Preferably, it also includes multiple sets of movable seats and multiple sets of clamping plates. Movable seats are movably mounted on the upper part of the clamping arm, and clamping plates are mounted on the outer end of the movable seats. When the clamping arms approach each other to clamp the sensor, the clamping plates first contact the sensor. The position of the clamping plates on the clamping arms can be adjusted by the movable seats to ensure the clamping area of ​​the sensor and improve the clamping quality.

[0009] Preferably, the bottom clamping component includes multiple sets of connecting plates, multiple sets of electric telescopic rods, and multiple sets of limiting plates. Connecting plates are symmetrically installed at the front and rear ends of the top of the base with respect to the clamping arms. The electric telescopic rods are installed on the connecting plates, and the telescopic ends of the electric telescopic rods are equipped with limiting plates. Activating the electric telescopic rods pushes the limiting plates to adjust the position, thereby adjusting the placement position and limiting and fixing the lower part of the sensor body.

[0010] Preferably, it also includes multiple support legs and a base plate. The multiple support legs are respectively installed at the four corners of the bottom of the base, the bottom of the support legs is on the top of the base plate, and the bottom of the fixing frame is connected to the top of the base plate. The support legs and the base plate support the bottom of the base, which facilitates the installation and fixing of the device.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: multiple sensor bodies are placed in the recessed groove at the top of the base, and the lower part of the sensor body can be limited and fixed by the bottom clamping component. The placement position can be adjusted, and the upper clamping component can clamp the upper side of the sensor body by pushing the component, so as to avoid the displacement during assembly, improve the assembly quality, and can clamp or disassemble the sensors at the same time, or clamp or disassemble the sensors individually, thus improving the practicality of the sensor fixture.

[0014] like Figures 1 to 5As shown, a recessed groove is provided at the top of the base 1. Multiple sets of fixed seats 4 are symmetrically installed on the front and rear side walls of the base 1. A rotating shaft 5 rotates on the fixed seat 4. A rotating rod 6 is installed on the outer wall of the rotating shaft 5. A clamping arm 7 is installed on the top of the rotating rod 6. A push arm 10 is installed at the bottom of the rotating rod 6. A bidirectional telescopic cylinder 15 is located below the base 1.

The guide sliders 14 are slidably installed on the outer wall of the guide slide rod 12 and in the guide slide groove. The bidirectional telescopic cylinder 15 is installed in the middle of the mounting base 13. The upper part of the clamping arm 7 is movably installed with a movable seat 8. The outer end of the movable seat 8 is installed with a clamping plate 9. The front and rear ends of the top of the base 1 are symmetrically installed with connecting plates 17 about the clamping arm 7. The electric telescopic rod 18 is installed on the connecting plate 17. The telescopic end of the electric telescopic rod 18 is installed with a limit plate 19. Multiple support legs 2 are installed at the four corners of the bottom of the base 1. The bottom of the support legs 2 is on the top of the base plate 3. The bottom of the fixing frame 11 is connected to the top of the base plate 3. The base 1 is supported by the outriggers 2 and the base plate 3, facilitating the installation and fixation of the device. Activating the electric telescopic rod 18 pushes the limiting plate 19 to adjust its position, thus fixing the lower part of the sensor body. After the sensor is placed on top of the base 1, the rotating shaft 5 and the rotating rod 6 rotate on the fixed seat 4, pushing the clamping arms 7 to rotate. This brings the two clamping arms 7 closer together to clamp the upper end of the sensor, preventing misalignment during assembly and improving assembly quality. Activating the bidirectional telescopic cylinder 15 pushes the push arm 10 through the connector 16. The output power causes the push arm 10 to push the rotating rod 6 to rotate on the fixed seat 4, which can clamp or remove the sensor separately. The bidirectional telescopic cylinder 15 is fixed by the mounting seat 13. When the bidirectional telescopic cylinder 15 pushes the push arm 10 to move, the mounting seat 13 drives the guide slider 14 to slide on the guide slide rod 12 to avoid motion interference. When the clamping arms 7 approach each other to clamp the sensor, the clamping plate 9 contacts the sensor first. The position of the clamping plate 9 on the clamping arm 7 can be adjusted by the movable seat 8 to ensure the clamping area of ​​the sensor and improve the clamping quality.

[0015] like Figures 1 to 5As shown, this utility model discloses a geomagnetic sensor assembly fixture. During operation, the base 1 is supported by the support legs 2 and the base plate 3. The electric telescopic rod 18 is activated to push the limiting plate 19 to adjust its position, thus limiting and fixing the lower part of the sensor body. After the sensor is placed on top of the base 1, the bidirectional telescopic cylinder 15 is activated, which drives the push arm 10 through the connector 16 to output power. This causes the push arm 10 to push the rotating rod 6 to rotate on the fixed seat 4. The sensor can be clamped or disassembled independently. The rotating shaft 5 and the rotating rod 6 rotate on the fixed seat 4. The clamping arms 7 are rotated so that the two clamping arms 7 move closer to each other to clamp the upper end of the sensor, preventing misalignment during assembly. The bidirectional telescopic cylinder 15 is fixed by the mounting base 13. When the bidirectional telescopic cylinder 15 pushes the push arm 10 to move, the mounting base 13 drives the guide slider 14 to slide on the guide slide rod 12 to avoid motion interference. When the clamping arms 7 move closer to each other to clamp the sensor, the clamping plate 9 contacts the sensor first. The position of the clamping plate 9 on the clamping arms 7 can be adjusted by the movable seat 8 to ensure the clamping area of ​​the sensor.
