Detailed Implementation
[0027] The present invention will now be described in further detail with reference to the accompanying drawings.
[0028] Please see Figure 1-4 As shown, this embodiment provides a testing device for a three-phase inductor, including a base 1 and a receiving drawer 2. The receiving drawer 2 is disposed inside the base 1. Clamping placement components 3 are fixedly installed on both sides inside the base 1. The receiving drawer 2 is located below the clamping placement components 3, which facilitates the collection of unqualified three-phase inductor bodies 4. The clamping placement components 3 are fixedly clamped inside the three-phase inductor bodies 4. A fixing frame 5 is fixedly fixed on the top of the base 1. A sliding groove is provided on the inner wall of the top of the fixing frame 5. A detachable movable testing component 6 is fixedly installed on one side inside the sliding groove. The sliding groove has a limiting effect on the detachable movable testing component 6, which improves the stability of the movement of the detachable movable testing component 6.
[0029] One application of this embodiment is as follows: The three-phase inductor body 4 to be tested is placed manually inside the clamping placement assembly 3. The clamping placement assembly 3 can clamp and fix three-phase inductor bodies 4 of different models and sizes. Then, the pins of the three-phase inductor body 4 can be tested using the detachable mobile test assembly 6, and the test head 608 of the detachable mobile test assembly 6 can be replaced, which facilitates testing of three-phase inductor bodies 4 of different models and reduces testing costs. The three-phase inductor bodies 4 that pass the test are kept inside the clamping placement assembly 3, while the three-phase inductor bodies 4 that fail the test fall into the receiving drawer 2 under the action of the clamping placement assembly 3 for unified collection and convenient subsequent processing.
[0030] The clamping placement assembly 3 includes a mounting plate 301. The mounting plate 301 is fixedly installed on both sides inside the base 1. The mounting plate 301 has an opening and a mounting slot. There are two mounting slots, which facilitates the simultaneous clamping and fixing of both sides of the three-phase inductor body 4, improving the fixing effect of the three-phase inductor body 4. The opening and the mounting slot are connected. A first electric push rod 302 is fixedly installed on one side inside the mounting slot. An L-shaped bracket 303 is fixed to the other end of the first electric push rod 302. A rubber pad 304 is fixedly installed on the inner wall of the bottom of the L-shaped bracket 303.
[0031] In this embodiment, an external controller is used to control the first electric push rod 302. The extension and retraction of the first electric push rod 302 can move the L-shaped bracket 303 and the rubber pad 304, so that three-phase inductor bodies 4 of different sizes can be clamped and fixed, facilitating the testing of three-phase inductor bodies 4 of different sizes. The top of the rubber pad 304 contacts the bottom of the three-phase inductor body 4, and the rubber pad 304 has a buffering effect on the three-phase inductor body 4 to avoid damage to the three-phase inductor body 4 during testing. When the three-phase inductor body 4 passes the test, the first electric push rod 302 maintains its original length. When the three-phase inductor body 4 fails the test, the first electric push rod 302 retracts, which can move the L-shaped bracket 303 and the rubber pad 304 into the mounting groove. The three-phase inductor body 4 that fails the test can fall into the receiving drawer 2 through the opening.
[0032] The detachable mobile test assembly 6 includes a second electric push rod 601 and a slider 602. One end of the second electric push rod 601 is fixedly installed inside one side of the slide groove, and one side of the slider 602 is fixed to the other end of the second electric push rod 601. The slider 602 slides and engages with the slide groove, improving the stability of the slider 602 during sliding. A third electric push rod 603 is fixedly installed at the bottom of the slider 602. A mounting bracket 604 is fixedly installed at the bottom of the third electric push rod 603. A mounting block 605 is provided inside the mounting bracket 604. Both sides of the mounting block 605 are provided with... A fixing slot is provided, and a spring 606 is fixedly installed inside the fixing slot. A locking block 607 is fixed to the other end of the spring 606. The locking block 607 is engaged with the mounting bracket 604. A test head 608 is fixedly installed at the bottom of the mounting block 605. A guide tube 609 is installed at the bottom of the test head 608. A tester 610 is fixedly installed at the top of the fixing bracket 5. A connecting wire 611 is installed at the rear of the tester 610. The connecting wire 611 can connect the tester 610 and the test head 608 together. The other end of the connecting wire 611 is fixedly installed at the rear of the test head 608.
[0033] In this embodiment, the test head 608 can be manually adjusted and controlled using the tester 610. Extending the third electric push rod 603 moves the test head 608 and guide cylinder 609 downwards, allowing the guide cylinder 609 to move to the pins of the three-phase inductor body 4, enabling testing of the three-phase inductor body 4 and displaying the test results on the tester 610 for easy viewing and recording by the tester. After testing, retracting the third electric push rod 603 moves the test head 608 and guide cylinder 609 upwards, separating the guide cylinder 609 from the pins of the three-phase inductor body 4. Then, extending the second electric push rod 601 moves the slider 602 within the groove, thereby moving the third electric push rod 603, test head 608, and guide cylinder 609, facilitating testing of the remaining three-phase inductor bodies 4 and improving testing efficiency.
[0034] When testing different models of three-phase inductor bodies 4 or replacing damaged test heads 608 and guide cylinders 609, press the locking block 607 into the fixing slot. At this time, the spring 606 is in a compressed state. The spring 606 has the ability to return to its original state. After the locking block 607 is completely moved into the fixing slot, the limiting effect of the mounting bracket 604 and mounting block 605 is released. The mounting block 605 can then be removed, reducing the maintenance cost and time of the testing device.
