Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic technology, specifically to a component testing fixture. Background Art
[0002] A three-phase ammeter is an electrical instrument used to measure the three-phase current in a circuit. It typically includes a power supply, a coil, and an ammeter to indicate the current reading. The main function of a three-phase ammeter is to measure the current in a three-phase circuit to facilitate the monitoring and management of the power system.
[0003] After a company completes the production of three-phase meters, it needs to test their functionality. This requires corresponding testing equipment. Currently, three-phase meter testing is still done manually using three-phase testing equipment. To test the performance of three-phase meters, it is often necessary to constantly adjust the current and voltage. This results in low efficiency for manual testing and makes it difficult to test the performance of three-phase meters in batches. Therefore, traditional performance testing of three-phase meters is done by sampling. Consequently, some three-phase meters may have insufficient performance, leading to inaccurate or unstable measurements when used by users.
[0004] Therefore, we propose a component testing fixture that facilitates the simultaneous testing of multiple three-phase meters, avoiding the difficulty of performing performance tests on batches of three-phase meters during manual testing. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a component testing fixture to solve the problems existing in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a component testing fixture, including a base, on which two sets of electric lifting rods are symmetrically installed front and back on the top surface of the base, and a fixing plate is fixed to the top of the two sets of electric lifting rods. Hydraulic cylinders are symmetrically arranged on the left and right sides of the center of the top surface of the base. The two sets of hydraulic cylinders are respectively connected to the left and right frames through two sets of telescopic rods. A three-phase electrical calibration structure is equidistantly installed on the top of the left frame. A support frame is connected to the top of the fixing plate through an electric slide rail. Four sets of three-phase meters are fixedly engaged on the top of the support frame, and the four sets of three-phase meters are distributed in pairs on the left and right.
[0007] Furthermore: a locking frame is installed on the top of the support frame, the locking frame has four locking areas reserved, and the four sets of three-phase meters are respectively pressed down and locked to the four locking areas.
[0008] Furthermore: two sets of rod-shaped limiting rods are fixed to the front and back of the top surface of the base. The two sets of limiting rods pass through the left and right frames respectively on the left and right sides. Limiting plates are symmetrically arranged on the left and right sides of the outer wall of the limiting rods.
[0009] Furthermore: the distance from the end of the limiting plate to the limiting rod is the movement range of the left or right frame.
[0010] Furthermore, a test probe is provided at the right end of the three-phase electrical calibration structure, and the position of the test probe corresponds to the position of the wiring hole of the three-phase meter.
[0011] Furthermore: the hydraulic cylinder drives the left frame to move from left to right via the telescopic rod, and the test pins of the three-phase electrical calibration structure on the top surface of the left frame slide and nest with the wiring holes of the three-phase meter.
[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0013] This utility model's component testing fixture, through the arrangement of an electric slide rail, support frame, left frame, right frame, and hydraulic cylinders, uses four sets of three-phase meters corresponding to the upper limit frames of the support frames for locking. When the electric slide rail is activated, it moves the three-phase meters and three-phase electrical calibration structures on the support frames to correspond. Then, two sets of hydraulic cylinders move the left and right frames from the outside to the inside, thereby causing the wiring holes of the three-phase meters on the left side of the support plate and the test probes of the AC tester on the left frame to slide and nest, and the wiring holes of the three-phase meters on the right side of the support plate and the test probes of the AC tester on the right frame to slide and nest. This facilitates the simultaneous testing of multiple three-phase meters, avoiding the difficulty of performing performance tests on batches of three-phase meters during manual testing.

Detailed Implementation
[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The structures involved in this utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example:
[0021] Please see Figure 1-4 This utility model provides a technical solution: a component testing fixture, including a base 15. Two sets of electric lifting rods 3 are symmetrically installed on the top front and back of the base 15. A fixing plate 4 is fixed to the top of the two sets of electric lifting rods 3, allowing adjustment of the height of the fixing plate 4. Hydraulic cylinders 6 are symmetrically arranged on the left and right sides of the center of the top surface of the base 15. The two sets of hydraulic cylinders 6 are connected to a left frame 1 and a right frame 2 respectively via two sets of telescopic rods 8, allowing adjustment of the positions of the left frame 1 and the right frame 2. A three-phase electrical calibration structure 7 is equidistantly installed on the top of the left frame 1. A support frame 10 is connected to the top of the fixing plate 4 via an electric slide rail 5, allowing the support frame 10 to be moved by the electric slide rail 5. Adjustments are made to fix four sets of three-phase meters 14 at the top of the support frame 10. The four sets of three-phase meters 14 are distributed in pairs on the left and right. By engaging the four sets of three-phase meters 14 with the upper limit frame of the support frame 10, the electric slide rail 5 is activated to drive the three-phase meters 14 on the support frame 10 to correspond with the three-phase electrical calibration structure 7. Then, the two sets of hydraulic cylinders 6 drive the left frame 1 and the right frame 2 to move from the outside to the inside. As a result, the wiring hole of the three-phase meter 14 on the left side of the support plate and the test needle 9 of the AC tester on the left frame 1 slide and nest. Similarly, the wiring hole of the three-phase meter 14 on the right side of the support plate and the test needle 9 of the AC tester on the right frame 2 slide and nest. Multiple three-phase meters 14 can be tested simultaneously, avoiding the difficulty of performing performance tests on batches of three-phase meters 14 during manual testing.
[0022] The three-phase electrical calibration structure 7 consists of a three-phase precision power source, meter holder, terminal blocks, pulse input / output, adjustment and control, display, instrument interface, computer, and dedicated software. Its actual parameters are as follows: voltage / current fundamental output 45Hz~2kHz, harmonics: 2~64th @ (45Hz~65Hz); maximum AC output capacity is 576V / 120A, ensuring stable output values under full load conditions; minimum AC current output as low as 0.1mA, which is the basis for starting tests of the tested energy meter; it supports multiple energy metering methods, including forward and reverse active energy, and four-quadrant reactive energy; it is equipped with a control panel, allowing observation or control of output values via its LCD touchscreen, facilitating manual meter calibration.
[0023] The support frame 10 is equipped with a locking frame 11 on its top. The locking frame 11 has four locking areas reserved. The four sets of three-phase meters 14 are respectively pressed down and locked to the four locking areas. The locking areas of the three-phase meters 14 in the locking frame 11 on the support frame 10 are pressed down and locked, thereby ensuring the stability of the three-phase meters 14 and the test probe 9 when they slide and nest.
[0024] The base 15 has two sets of rod-shaped limiting rods 13 fixed to its top front and back. The two sets of limiting rods 13 pass through the left frame 1 and the right frame 2 on the left and right sides respectively. The limiting rods 13 are symmetrically provided with limiting plates 12 on the left and right sides of their outer walls. By passing through the left and right sides of the limiting rods 13, the left frame 1 and the right frame 2 are in a linear shape during movement, thus preventing the left frame 1 from being misaligned during movement.
[0025] The distance between the end of the limiting plate 12 and the limiting rod 13 is the movement range of the left frame 1 or the right frame 2. The left frame 1 moves by the hydraulic cylinder 6 and the telescopic rod 8, and stops when the left frame 1 moves to the limiting plate 12 to prevent the left frame 1 from exceeding the range.
[0026] The three-phase electrical calibration structure 7 is provided with a test pin 9 at its right end. The position of the test pin 9 corresponds to the position of the wiring hole of the three-phase meter 14. The test pin 9 is used to test the nesting of the wiring hole of the three-phase meter 14.
[0027] The hydraulic cylinder 6 drives the left frame 1 to move from left to right via the telescopic rod 8, and the test pin 9 of the three-phase electrical calibration structure 7 on the top surface of the left frame 1 slides and nests with the wiring hole of the three-phase meter 14.
[0028] The working principle of this utility model embodiment is as follows: The three-phase meter 14 is pressed down and locked in the locking area of the locking frame 11 on the support frame 10. The four sets of three-phase meters 14 are distributed in pairs on the left and right, and the orientation and location of the three-phase meters 14 are consistent. By locking the upper limit frame of the support frame 10 corresponding to the four sets of three-phase meters 14, the electric slide rail 5 is started to drive the three-phase meters 14 on the support frame 10 to correspond with the three-phase electrical calibration structure 7. Then, the left frame 1 and the right frame 2 are moved from the outside to the inside by the two sets of hydraulic cylinders 6 respectively. Then, the wiring hole of the three-phase meter 14 on the left side of the support plate and the test needle 9 of the AC tester on the left frame 1 slide nested. Then, the wiring hole of the three-phase meter 14 on the right side of the support plate and the test needle 9 of the AC tester on the right frame 2 slide nested. Then, the three-phase electrical calibration structure 7 is started. After the measurement is completed, the left frame 1 and the right frame 2 are moved from the inside to the outside by the two sets of hydraulic cylinders 6. Then, the electric slide rail 5 is started to send the support plate outward.
