Description

Technical Field

[0001] This utility model relates to the field of sensor testing technology, and in particular to a batch testing fixture for a circuit breaker mechanical characteristic angle sensor. Background Technology

[0002] In current power systems, circuit breakers, as crucial switching devices, directly affect the safe and stable operation of the power system due to their mechanical characteristics. To monitor the mechanical condition of circuit breakers in real time and prevent potential faults, angle sensors are widely used for online monitoring of their mechanical characteristics. However, with the continuous expansion of power system scale and the increasing number of circuit breakers, how to efficiently and accurately conduct batch testing of these angle sensors has become an urgent problem to solve.

[0003] In existing technologies, multiple angular displacement sensors are connected through the cooperation of drive motors and linkage mechanisms to facilitate unified testing.

[0004] In the manufacturing process of angular displacement sensors, accurate testing of their performance is a key step in ensuring product quality. Currently, it is difficult to guarantee the consistency and accuracy of testing during batch testing. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a batch testing fixture for circuit breaker mechanical characteristic angle sensors, including a bracket, a base plate, a fixing unit, multiple angle displacement sensors, multiple rotating shafts, multiple synchronous follow-up mechanisms, and a linkage mechanism. The bracket includes a vertical plate, a first horizontal plate, a second horizontal plate, and a third horizontal plate.

The first horizontal plate is located at the upper end of the second horizontal plate, and the third horizontal plate is located at the lower end of the second horizontal plate. The base plate is disposed at the upper end of the first horizontal plate. Multiple angle displacement sensors are respectively disposed on the base plate. Multiple synchronous follow-up mechanisms are respectively disposed at the upper end of the second horizontal plate. The linkage mechanism is disposed on the bracket. Multiple rotating shafts are respectively fixedly connected to the lower end of the corresponding angle displacement sensor. The lower ends of the multiple rotating shafts pass through the base plate and the first horizontal plate and are connected to the corresponding synchronous follow-up mechanism.

[0007] Each of the synchronous follow-up mechanisms includes a base, a coupling, a main shaft, and a first synchronous gear. The base is fixedly connected to the upper end of the second horizontal plate, the main shaft is rotatably connected to the upper end of the base, the first synchronous gear is fixedly sleeved on the outside of the main shaft, and the coupling is disposed on the upper end of the main shaft.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] This utility model provides a batch testing fixture for angle displacement sensors 18, including a bracket, a base plate 1, a fixing unit, multiple angle displacement sensors 18, multiple rotating shafts 2, multiple synchronous follow-up mechanisms, and a linkage mechanism. The bracket includes a vertical plate 3, a first horizontal plate 4, a second horizontal plate 5, and a third horizontal plate 6. The first horizontal plate 4, the second horizontal plate 5, and the third horizontal plate 6 are respectively fixedly connected to the front end of the vertical plate 3. The first horizontal plate 4 is located at the upper end of the second horizontal plate 5, and the third horizontal plate 6 is located at the lower end of the second horizontal plate 5. The base plate 1 is disposed at the upper end of the first horizontal plate 4. The multiple angle displacement sensors 18 are respectively disposed on the base plate 1. The multiple synchronous follow-up mechanisms are respectively disposed at the upper end of the second horizontal plate 5. The linkage mechanism is disposed on the bracket. The multiple rotating shafts 2 are respectively fixedly connected to the lower end of the corresponding angle displacement sensor 18. The lower ends of the multiple rotating shafts 2 pass through the base plate 1 and the first horizontal plate 4, and are connected to the corresponding synchronous follow-up mechanism.

[0020] In this embodiment, the linkage mechanism drives multiple synchronous follow-up mechanisms to rotate, and then, with the cooperation of multiple rotating shafts 2, drives multiple angle displacement sensors 18 to rotate at the same angle. This allows the staff to compare the angle data of multiple angle displacement sensors 18 through the background system to test the performance of the angle displacement sensors 18. Thus, the device can perform batch testing of multiple angle displacement sensors 18 with high accuracy.

[0021] Further, each of the synchronous follow-up mechanisms includes a base 7, a coupling 8, a main shaft 9, and a first synchronous gear 10. The base 7 is fixedly connected to the upper end of the second horizontal plate 5, the main shaft 9 is rotatably connected to the upper end of the base 7, the first synchronous gear 10 is fixedly sleeved on the outside of the main shaft 9, and the coupling 8 is disposed on the upper end of the main shaft 9. The linkage mechanism includes a stepper motor 11, a second synchronous gear 12, two first belts 13, and two second belts 14. The second horizontal plate 5 has an opening 15, the stepper motor 11 passes through the opening 15, and is disposed on the upper end of the third horizontal plate 6. The second synchronous gear 12 is disposed on the output end of the stepper motor 11. One end of each of the two first belts 13 is adapted to the second synchronous gear 12, and the other end of each of the two first belts 13 is adapted to the first synchronous gear 10. Each of the two second belts 14 is adapted to the corresponding synchronous follow-up mechanism, and each of the two second belts 14 is adapted to the first synchronous gear 10.

[0022] In this embodiment, the output end of the stepper motor 11 drives the second synchronous gear 12 to rotate, which in turn drives the two second belts 14 to rotate. Under the rotation of the two second belts 14, the first synchronous gear 10 included in the corresponding synchronous follow-up mechanism is driven to rotate. Then, under the drive of the corresponding first belt 13, all the first synchronous gears 10 are driven to rotate, which in turn drives the main shaft 9 and the coupling 8 to rotate. Through the cooperation of the coupling 8 and the rotating shaft 2, the multiple angle displacement sensors 18 are driven.

[0023] Furthermore, the fixing unit includes a plurality of first bolts 16 and a plurality of second bolts 17. The plurality of first bolts 16 pass through the base plate 1 and are respectively located inside the first horizontal plate 4. The plurality of second bolts 17 pass through the base plate 1 and are respectively disposed in the corresponding angle displacement sensor 18.

[0024] In this embodiment, the base plate 1 is placed on the first horizontal plate 4 by setting multiple first bolts 16, and the corresponding angle displacement sensor 18 is installed on the base plate 1 by setting multiple second bolts 17. The angle displacement sensor 18 is connected to the multiple second bolts 17 through the bottom rotating plate, so it will not affect the normal rotation test of the angle displacement sensor 18.
