Description

Technical Field

[0001] The invention belongs to the technical field of testing devices, in particular to a performance testing device for current transformer production. Background Art

[0002] A current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side for measurement based on the principle of electromagnetic induction. During the production process of current transformers, they will be subjected to performance tests. Through performance tests, defective and substandard products can be detected to prevent them from entering the market.

[0003] The patent with announcement number CN217467148U discloses a performance testing device for current transformer production, including a main body, a cylinder connected to the top of the inner wall of the main body, a telescopic column connected to one end of the cylinder, a fixed block connected to one end of the telescopic column, a connecting block connected to one side of the fixed block, a test device body is arranged inside the connecting block, a workbench is connected to the bottom of the inner wall of the main body, a fixed plate is connected to the top of the workbench, a placement chamber is arranged at the bottom of the workbench, and a placement rack is connected to one side of the inner wall of the placement chamber. In this patent, by arranging the cylinder and the telescopic column, the height of the device can be adjusted. When conducting the test, the operation becomes simple and time-saving, thereby improving the work efficiency of the staff. By arranging the dust removal device, the dust on the test bench can be cleaned to prevent the dust from affecting the test results and reduce the error of the test results.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The current transformer is tested by aligning the detection probe of the detection device with the pin of the current transformer. Since the detection probe needs to be aligned with the pin of the current transformer, it is necessary to manually adjust the position of the current transformer so that the pin is aligned with the detection probe. When there are a large number of current transformers to be tested for performance, it is laborious to manually adjust the position of the current transformers one by one, which can easily cause fatigue to the workers. In addition, it is inconvenient to separate qualified products from defective products. After the test, confusion is likely to occur when the current transformers are collected.

If the current sensor is a qualified product, the test bench continues to rotate, and at the same time, the motor 1 also drives the adjusting plate to rotate. When the push plate pushes the current sensor again, the current sensor will drop onto the second receiving column, thereby realizing the separate collection of the defective current sensors and the qualified current sensors, facilitating subsequent unified processing, not prone to confusion, and being more convenient.

[0047] Specifically, a current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side for measurement based on the principle of electromagnetic induction. During the production process of the current transformer, it will be subjected to performance testing. Through performance testing, defective and inferior products can be detected to prevent the inferior products from entering the market.

[0048] When the existing performance test device for current transformer production is used, the current transformer is tested by aligning the detection probe 8 of the detection device with the pin of the current transformer. Since the detection probe 8 needs to be aligned with the pin of the current transformer, it is necessary to manually adjust the position of the current transformer so that the pin is aligned with the detection probe 8. When there are a large number of current transformers to be tested, it is laborious to manually adjust the position of the current transformers one by one, which is easy to cause fatigue to the workers. In addition, it is inconvenient to separate qualified products and defective products, which is easy to cause confusion.

[0049] Therefore, in order to solve the above problems, when the present embodiment is used, the current transformer to be tested for performance is placed in the feed chamber 4, and the current transformer will slide downward along the channel of the feed chamber 4 under the action of gravity. Since the size of the opening at the bottom of the feed chamber 4 can only allow the current transformer placed horizontally to continue to be fed, and the current transformer placed upright will be blocked by the bottom of the feed chamber 4, the current transformers that slide to the channel at the bottom of the feed chamber 4 are all in a horizontal state. At the same time, the motor three 14 is turned on to drive the turntable 15 to rotate, and the lever 16 can be used to separate adjacent current transformers. With the intermittent rotation of the turntable 15, the intermittent falling of the current transformer can be realized, and in conjunction with the rotation of the test bench 10, the current transformer can be dropped onto the placement plate 20. At the same time, the visual detection device 32 can be used to detect the positive and negative direction and angle of the current sensor, and then the motor six 23 drives the bidirectional threaded rod 24 to rotate, and the two adjustment blocks 28 are close to each other. When the current sensor is close, the clamping block 21 can be used to clamp the current sensor. If the pin of the current sensor is not facing upward, the electric push rod 27 will drive the lifting frame 26 to rise, and then the motor 5 22 will drive the clamping block 21 to rotate, so that the current sensor can be flipped so that its pin faces upward. At the same time, the motor 4 18 is used to drive the rotating frame 19 to rotate, so that the placement plate 20 and the current sensor can be rotated to adjust the angle of its pin, and as the test bench 10 rotates, it is located below the detection probe 8. At this time, the detection probe 8 is just aligned with the pin of the current sensor, and then the current sensor is driven to rise again, so that the pin of the current sensor can be contacted with the detection probe 8 for testing. Therefore, the automatic test of the current sensor can be realized by simply placing multiple current sensors into the feeding chamber 4 at the same time, eliminating the process of manually placing the current sensor and aligning its pin with the detection probe 8, which is more convenient and improves the test efficiency.

[0050] When the current sensor tested by the test device body 7 is a defective product, the two clamping blocks 21 release the current sensor, and then the electric push rod 2 36 drives the push plate 34 to approach the current sensor and push the current sensor to make it fall onto the receiving column 2. If the current sensor is a qualified product, the test bench 10 continues to rotate. At the same time, the motor 1 6 also drives the adjustment plate 33 to rotate. When the push plate 34 pushes the current sensor again, the current sensor will fall onto the receiving column 2 3, thereby realizing the separate collection of defective current sensors and qualified current sensors, which is convenient for subsequent unified processing, not easy to confuse, and more convenient.

[0051] Thus, by utilizing the positioning adjustment mechanism and the anti-stuck intermittent drop mechanism, the automatic test of the current sensor can be realized by simply placing multiple current sensors into the feed chamber 4 at the same time, eliminating the need for manual placement of the current sensor and aligning its pins with the detection probe 8. This is more convenient and improves the test efficiency. In addition, when the current sensor tested by the test device body 7 is a defective product, the two clamping blocks 21 release the current sensor, and then the electric push rod 2 36 drives the push plate 34 to approach the current sensor and push the current sensor to make it fall onto the receiving column 1 2. If the current sensor is a qualified product, the test bench 10 continues to rotate, and at the same time, the motor 1 6 also drives the adjustment plate 33 to rotate. When the push plate 34 pushes the current sensor again, the current sensor will fall onto the receiving column 2 3, thereby realizing the separate collection of defective current sensors and qualified current sensors, facilitating subsequent unified processing, not easy to confuse, and more convenient.

[0052] In this embodiment, Figure 2 and Figure 3 As shown, a shift plate 12 is rotatably provided on one side of the feed chamber 4 , a motor 2 13 is fixedly connected to one side of the front end surface of the feed chamber 4 , and an output end of the motor 2 13 is fixedly connected to the shift plate 12 .

[0053] Specifically, when the current transformer falls with the feed chamber 4, the motor 2 13 drives the paddle 12 to rotate continuously, and the paddle 12 can be used to push the current transformer in the feed chamber 4 to promote the falling of the current transformer, thereby avoiding the situation where the subsequent testing work cannot be carried out normally due to the current transformer being blocked inside the feed chamber 4.

[0054] Working principle: put the current transformer to be tested for performance into the feeding chamber 4, and the current transformer will slide down along the channel of the feeding chamber 4 under the action of gravity. Since the size of the opening at the bottom of the feeding chamber 4 can only allow the current transformer placed horizontally to continue to be fed, and the current transformer standing upright will be blocked by the bottom of the feeding chamber 4, the current transformers that slide to the channel at the bottom of the feeding chamber 4 are all in a horizontal state. At the same time, start the motor 14 to drive the turntable 15 to rotate, and the lever 16 can be used to separate the adjacent current transformers. With the intermittent rotation of the turntable 15, the intermittent drop of the current transformer can be realized, and the current transformer can be equipped with The test bench 10 is rotated to make the current transformer fall above the placement plate 20. At the same time, the visual detection device 32 can detect the positive and negative directions and angles of the current sensor. Then, the motor 6 23 drives the bidirectional threaded rod 24 to rotate, and the two adjustment blocks 28 are close to each other. The current sensor can be clamped by the clamping block 21. If the pin of the current sensor is not facing upward, the electric push rod 1 27 will drive the lifting frame 26 to rise, and then the motor 5 22 drives the clamping block 21 to rotate, so that the current sensor can be flipped over so that its pin faces upward. At the same time, the motor 4 18 drives the rotating frame 19 to rotate, so that the placement plate 20 can be turned over. The tray 20 and the current sensor are rotated to adjust the angle of the pins thereof, and as the test bench 10 rotates, they are located below the detection probe 8. At this time, the detection probe 8 is just aligned with the pins of the current sensor, and then the current sensor is driven up again, so that the pins of the current sensor can be brought into contact with the detection probe 8 for testing. Thus, the automatic testing of the current sensor can be realized by simply placing a plurality of current sensors into the feed chamber 4 at the same time, eliminating the need for manual placement of the current sensor and aligning its pins with the detection probe 8, which is more convenient and improves the testing efficiency. When the testing device body 7 is When the tested current sensor is a defective product, the two clamping blocks 21 release the current sensor, and then the electric push rod 2 36 drives the push plate 34 to approach the current sensor and push the current sensor to make it fall onto the receiving column 2. If the current sensor is a qualified product, the test bench 10 continues to rotate. At the same time, the motor 1 6 also drives the adjustment plate 33 to rotate. When the push plate 34 pushes the current sensor again, the current sensor will fall onto the receiving column 2 3, thereby realizing the separate collection of defective current sensors and qualified current sensors, which is convenient for subsequent unified processing, not easy to confuse, and more convenient.Therefore, by utilizing the positioning adjustment mechanism and the anti-stuck intermittent drop mechanism, the automatic test of the current sensor can be realized by simply placing multiple current sensors into the feed chamber 4 at the same time, eliminating the need for manual placement of the current sensor and aligning its pins with the detection probe 8. This is more convenient and improves the test efficiency. In addition, when the current sensor tested by the test device body 7 is a defective product, the two clamping blocks 21 release the current sensor, and then the electric push rod 2 36 drives the push plate 34 to approach the current sensor and push the current sensor to make it fall onto the receiving column 1 2. If the current sensor is a qualified product, the test bench 10 continues to 4, and the feed chamber 4 is provided with a plurality of control plates 12, and the plurality of control plates 13 are provided with a plurality of control plates 14. The plurality of control plates 12 are provided with a plurality of control plates 14, and the plurality of control plates 14 are provided with a plurality of control plates 15.
