Description

Technical Field

[0001] This utility model relates to the technical field of circuit switch testing devices, and in particular to an automatic circuit switch opening and closing testing device. Background Technology

[0002] Circuit switches control the flow of current within power lines. Closing the circuit switch allows current to flow, thus supplying power, while opening the circuit switch blocks current flow, thus disconnecting the power supply. As a commonly used electrical component, circuit switches must comply with national standards regarding their switching lifespan. Therefore, after manufacturing, circuit switches undergo random sampling and opening / closing number tests to determine if they meet the requirements.

[0003] Existing automatic circuit switch opening and closing test devices typically require an operator to place the circuit switch on an automatic swing device, which then performs the opening and closing test. However, during the test, the circuit switch lacks relative limiting clamping, which can cause the circuit switch to slip unexpectedly, leading to errors in the test results. Therefore, this utility model proposes an automatic circuit switch opening and closing test device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the circuit switch lacks relative limiting clamping during testing, leading to accidental slippage of the circuit switch and resulting in errors in the test results. Therefore, this invention proposes an automatic opening and closing test device for circuit switches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Test bench;

[0009] A bonding frame, wherein there are multiple bonding frames, and the left and right ends of the bonding frame are slidably connected to the sides of two fixed plates that are close to each other;

[0010] The fixing mechanism and the bonding mechanism are in multiple sets, and the fixing mechanism cooperates with the bonding frame, the fixing plate and the bonding mechanism respectively;

[0011] The testing mechanism is provided in multiple sets, and each testing mechanism includes: two fixed frames, a testing frame, and a motor.

[0012] Both fixed frames are fixedly connected to the test bench, the test frame is rotatably connected to the two fixed frames, the motor is fixedly connected to the fixed frame located at the front, the motor output shaft passes through the fixed frame located at the front, and the motor output shaft is fixedly connected to the test frame.

[0013] As a preferred embodiment of this utility model, the fixing mechanism includes: a positioning frame, a spring, and a driving rod;

[0015] As a preferred embodiment of this utility model, the bonding mechanism includes: a pulling rod, a pushing frame, a rotating rod, and a connecting rod;

[0016] The pull rod is rotatably connected to the push frame and the drive rod located on the right side. The push frame is slidably connected to the top of the bonding frame. The connecting rod is rotatably connected to the drive rod and the rotating rod located on the left side. The rotating rod is rotatably connected to the bonding frame. Both the rotating rod and the connecting rod are in slidable contact with the push frame.

[0017] As a preferred embodiment of this utility model, multiple positioning grooves are fixedly installed on one side of the two fixing plates that are close to each other, and positioning blocks are fixedly installed on the positioning frame. The positioning blocks can be detachably engaged with the inner wall of the positioning grooves.

[0019] As a preferred embodiment of this utility model, the top of the bonding frame is provided with a horizontal sliding groove, and the bottom of the pushing frame is slidably connected to the inner wall of the horizontal sliding groove.

[0020] Beneficial effects:

[0021] 1. After the positioning frame and the fixed frame are engaged, the positioning frame can connect the bonding frame and the fixed frame to position the bonding frame on the fixed frame, so that the bonding frame can stably clamp and fix the circuit switch.

[0022] 2. After the pusher is pushed, it can drive the rotating rod to rotate and pull the pulling rod, so that the pulling rod can pull the driving rod on the right side and drive the rotating rod to rotate, so that the rotating rod can pull the connecting rod, and the connecting rod can pull the driving rod on the left side, so that the two driving rods can move closer to each other, which can move the two positioning frames closer to each other, so that the two positioning frames can be separated from the two fixed frames, and the bonding frame at the current position can be unlocked to adjust the position of the bonding frame at the current position. Unlocking the two bonding frames and pushing the two bonding frames closer to each other can clamp the multiple circuit switches on the top of the test platform. Then, the pusher is released, and the pusher releases the two positioning frames, so that the two positioning frames can automatically engage with the fixed frame through the spring rebound to stably clamp the circuit switches. Then, the motor is started, and the motor drives the test frame to rotate forward and then reverse, so that the circuit switches can be tested through the test frame.

[0023] In this invention, by controlling the distance between the two bonding frames at the top of the test bench, the bonding frames can simultaneously clamp and limit multiple circuit switches, preventing the circuit switches from shaking during testing and avoiding errors during testing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example

[0031] Reference Figures 1-4 An automatic circuit switch opening and closing test device, comprising:

[0032] Test bench 1;

[0033] Fixing plate 5, there are two fixing plates 5, and both fixing plates 5 are fixedly installed on the top of the test bench 1;

[0034] There are multiple bonding frames 6, and the left and right ends of the bonding frames 6 are slidably connected to the sides of the two fixing plates 5 that are close to each other.

[0035] The fixing mechanism and the bonding mechanism are in multiple sets. The fixing mechanism cooperates with the bonding frame 6, the fixing plate 5 and the bonding mechanism respectively.

[0036] The testing mechanism consists of multiple sets, including: two fixed frames 2, a test frame 3, and a motor 4;

[0037] Both fixed frames 2 are fixedly connected to the test bench 1. The test frame 3 is rotatably connected to the two fixed frames 2. The motor 4 is fixedly connected to the fixed frame 2 located at the front side. The output shaft of the motor 4 passes through the fixed frame 2 located at the front side and is fixedly connected to the test frame 3.

[0038] With the above structure, by controlling the distance between the two bonding frames 6 at the top of the test bench 1, the bonding frames 6 can simultaneously clamp and limit multiple circuit switches, preventing the circuit switches from shaking during testing and avoiding errors during testing.

[0039] As a preferred embodiment of the present invention, the fixing mechanism includes: a positioning frame 7, a spring 8, and a driving rod 9;

[0040] The positioning frame 7 cooperates with the bonding frame 6. The positioning frame 7 is fixedly connected to the spring 8 and the driving rod 9 respectively. The spring 8 is fixedly connected to the bonding frame 6. After the positioning frame 7 engages with the fixed frame 2, the positioning frame 7 can connect the bonding frame 6 and the fixed frame 2 to position the bonding frame 6 on the fixed frame 2, so that the bonding frame 6 can stably clamp and fix the circuit switch.

[0041] As a preferred embodiment of this utility model, the bonding mechanism includes: a pulling rod 10, a pushing frame 11, a rotating rod 12, and a connecting rod 13;

[0042] Pull rod 10 is rotatably connected to push frame 11 and drive rod 9 located on the right side. Push frame 11 is slidably connected to the top of bonding frame 6. Connecting rod 13 is rotatably connected to drive rod 9 located on the left side and rotating rod 12. Rotating rod 12 is rotatably connected to bonding frame 6. Both rotating rod 12 and connecting rod 13 are in slidable contact with push frame 11. After push frame 11 is pushed, push frame 11 can push rotating rod 12 to rotate and pull pull rod 10, so that pull rod 10 can pull drive rod 9 on the right side and push rotating rod 12 to rotate, so that rotating rod 12 can pull connecting rod 13, and connecting rod 13 can pull drive rod 9 on the left side, so that the two drive rods 9 can interact with each other. By bringing them closer together, the two positioning frames 7 can be moved closer to each other, allowing them to disengage from the two fixed frames 2. This unlocks the bonding frame 6 at the current position, allowing adjustment of its position. Unlocking the two bonding frames 6 and pushing them closer together clamps multiple circuit switches on the top of the test bench 1. Then, releasing the push frame 11 releases the two positioning frames 7, allowing them to automatically engage with the fixed frames 2 via the spring 8, stably clamping the circuit switches. Finally, starting the motor 4 causes the test frame 3 to rotate forward and then reverse, allowing the circuit switches to be tested via the test frame 3.

[0043] As a preferred embodiment of this utility model, multiple positioning grooves are fixedly installed on the side of the two fixing plates 5 that are close to each other, and positioning blocks are fixedly installed on the positioning frame 7. The positioning blocks can be disengaged from the inner wall of the positioning grooves. After the positioning blocks engage with the positioning grooves, the positioning blocks can block the movement of the bonding frame 6, thereby achieving the positioning of the bonding frame 6.

[0044] As a preferred embodiment of this utility model, the left and right ends of the fitting frame 6 are provided with rectangular grooves, and the positioning frame 7 is slidably connected to the inner wall of the rectangular groove. The rectangular groove is used to install the positioning frame 7, so that the positioning frame 7 can automatically engage with the fixing frame 2.

[0045] As a preferred embodiment of this utility model, the top of the bonding frame 6 is provided with a horizontal sliding groove, and the bottom of the push frame 11 is slidably connected to the inner wall of the horizontal sliding groove. The horizontal sliding groove is used to install the bonding frame 6, so that the bonding frame 6 can be stably positioned with the circuit switch.

[0046] The working principle of this utility model is as follows: When testing circuit switches, multiple circuit switches are first placed on the top of the test bench 1. Then, the pusher 11 on the top of the two bonding frames 6 at the current position is pushed. After the pusher 11 is pushed, it can push the rotating rod 12 to rotate and pull the pulling rod 10. This allows the pulling rod 10 to pull the driving rod 9 on the right side, and pushes the rotating rod 12 to rotate. This allows the rotating rod 12 to pull the connecting rod 13, which in turn pulls the driving rod 9 on the left side. This allows the two driving rods 9 to move closer together, which in turn moves the two positioning frames 7 closer together, allowing them to separate from the two fixed frames 2. This allows the bonding frame 6 at the current position to be tested. Unlock the two bonding frames 6 to adjust their position. Push the two bonding frames 6 closer together to clamp the multiple circuit switches on the top of the test platform 1. Then release the push frame 11, which will release the two positioning frames 7. The two positioning frames 7 will automatically engage with the fixed frame 2 due to the spring 8. After the positioning frames 7 engage with the fixed frame 2, they can connect the bonding frame 6 and the fixed frame 2 to position the bonding frame 6 on the fixed frame 2. This allows the bonding frame 6 to stably clamp and fix the circuit switches. Then start the motor 4. The motor 4 will drive the test frame 3 to rotate forward and then reverse, allowing the circuit switches to be tested through the test frame 3.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
