Description
Technical Field
[0001] This utility model relates to the field of volt-ampere testing technology, and in particular to a volt-ampere testing fixture. Background Technology
[0002] The voltmeter-ammeter method detects resistance by measuring the voltage across a conductor and the current flowing through it. Specifically, the experimental principle of the voltmeter-ammeter method for measuring resistance is Ohm's law. In the experiment, a voltmeter is used to measure the voltage across the conductor, and an ammeter is used to measure the current flowing through it. The voltmeter-ammeter test fixture is inconvenient and slow to operate due to its cumbersome structure, and it is especially difficult for new employees to get started.
[0003] Common volt-ampere test fixtures only include testing functions and can test magnetic cores, but they lack the function to improve testing speed. As a result, the testing speed cannot be guaranteed, and the volt-ampere test fixtures are inconvenient and slow to operate due to their complicated structure. In particular, it is difficult for new employees to get started, which affects the testing speed.
[0004] Therefore, in view of the problem that the above-mentioned volt-ampere test fixture is limited by its structural complexity and cumbersome process, resulting in difficulty in improving the test speed and more significant time consumption, there is an urgent need to design a new type of volt-ampere test fixture. Utility Model Content
[0005] To overcome the problem that common volt-ampere test fixtures are limited by structural complexity and cumbersome processes, making it difficult to improve testing speed and significantly increasing testing time.
[0006] The technical solution of this utility model is as follows: a volt-ampere testing fixture, including a worktable; it also includes a detection groove, connecting rods, a support plate, a volt-ampere detector body, a left side plate, a right side plate, a motor, a drive block, a lead screw, a cylinder, and a U-shaped material handling plate. A detection groove is provided on the right side of the top center of the worktable. Four connecting rods are rectangularly arranged on the right side of the bottom of the worktable. The bottom end of the connecting rods is connected to the support plate. The volt-ampere detector body is arranged on the top of the support plate. The test end of the top of the volt-ampere detector body is inserted into the detection groove. A left side plate is arranged at the front end of the left side of the top of the worktable. A right side plate is arranged at the front end of the right side of the top of the worktable. A motor is arranged on the right side of the right side plate. A drive block is arranged on the front side of the top of the worktable. A lead screw is arranged in the middle of the left side plate and the right side plate corresponding to the position of the drive block. A cylinder is arranged on the front side of the drive block. The output end of the cylinder passes through the drive block and is connected to the U-shaped material handling plate.
[0007] Preferably, by placing the voltmeter / ammeter body at the bottom of the workbench, with the testing end of the voltmeter / ammeter body flush with the top surface of the workbench, the magnetic cores can be pushed over one by one from the table for voltmeter / ammeter testing without having to pick them up. The magnetic core is then placed inside the U-shaped limiting frame, and the motor is started via the PLC controller. The motor drives the drive block via a lead screw to move to the position of the magnetic core. At this point, the end of the L-shaped sliding plate away from the drive block slides inside the groove. Then, the PLC controller starts the cylinder, which drives the U-shaped picking plate to move towards the magnetic core until the entire magnetic core is completely inserted into the U-shaped picking plate. The PLC controller then controls the entire process. The controller restarts the motor, which drives the drive block to move towards the detection slot via a lead screw. The drive block then moves the magnetic core inside the U-shaped limit frame via a U-shaped material pick-up plate until the magnetic core moves to the top of the detection slot. Finally, the test is performed through the test end of the volt-ampere tester, thus improving the testing speed. This addresses the problem that common volt-ampere test fixtures only include testing functions and can test magnetic cores, but lack the function to improve testing speed. As a result, the volt-ampere test fixtures are often inconvenient and slow to operate due to their cumbersome structure, which is especially difficult for new employees to learn, thus affecting the testing speed.
[0008] Preferably, the lead screw is threadedly connected to the drive block, the left end of the lead screw is rotatably connected to the left side plate, and the right end of the lead screw passes through the right side plate and is connected to the output end of the motor.
[0009] Preferably, a U-shaped limiting frame is provided on the left side of the top center of the workbench, corresponding to the position of the detection slot, and the U-shaped material picking plate is located at the top of the U-shaped limiting frame.
[0010] Preferably, two L-shaped sliding plates are symmetrically arranged on the front and rear sides of the drive block, and two sliding grooves are opened on the top of the worktable corresponding to the positions of the two L-shaped sliding plates. The end of the L-shaped sliding plate away from the drive block is inserted into the interior of the sliding groove.
[0011] Preferably, four support legs are provided at the four corners of the bottom of the workbench, and a connecting frame is provided at the right end of the rear side of the workbench corresponding to the position of the detection groove.
[0012] Preferably, a storage box is provided inside the connecting frame, and hooks are symmetrically provided on the left and right sides of the top of the storage box, and the storage box is fixed to the connecting frame by the hooks.
[0013] Preferably, a PLC controller is installed at the rear end of the top left side of the workbench.
[0014] The beneficial effects of this utility model are:
[0015] 1. Install the voltmeter-ampere tester body on the bottom of the workbench, with its testing end flush with the top surface of the workbench. The magnetic core can be directly pushed into the testing area along the table without manual handling. During operation, after the magnetic core is guided into the positioning area of the U-shaped limiting frame, the PLC controller triggers the motor to run, and the drive block moves to the corresponding position of the magnetic core through the lead screw transmission. At this time, the end of the L-shaped sliding plate slides and positions synchronously in the slide groove. Then, the PLC controller activates the cylinder to push the U-shaped picking plate to accurately approach the magnetic core until the magnetic core is completely embedded in the clamping structure of the U-shaped picking plate. Finally, the PLC controller restarts the motor, and the drive block drives the U-shaped picking plate and the magnetic core to slide along the U-shaped limiting frame to directly above the testing slot via the lead screw. The testing end of the voltmeter-ampere tester body completes the automatic testing. The testing efficiency is improved through mechanical linkage and programmed control. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5This utility model provides an embodiment of a voltammetry testing fixture, including a worktable 1; it also includes a detection groove 2, connecting rods 3, a support plate 4, a voltammetry detector body 5, a left side plate 7, a right side plate 8, a motor 9, a drive block 10, a lead screw 11, a cylinder 12, and a U-shaped material handling plate 13. The detection groove 2 is located on the right side of the top center of the worktable 1. Four connecting rods 3 are arranged in a rectangle on the right side of the bottom of the worktable 1. The bottom ends of the connecting rods 3 are connected to the support plate 4. The voltammetry detector body 5 is located on the top of the support plate 4. The testing end of the voltammetry detector body 5 is inserted into the detection groove 2. A left plate 7 is located at the front end of the top left side of the worktable 1, and a right plate 8 is located at the front end of the top right side of the worktable 1. A motor 9 is located on the right side of the right plate 8. A drive block 10 is located on the front side of the top of the worktable 1. A lead screw 11 is located between the left plate 7 and the right plate 8, corresponding to the position of the drive block 10. A cylinder 12 is located on the front side of the drive block 10. The output end of the cylinder 12 passes through the drive block 10 and is connected to a U-shaped material picking plate 13. By placing the voltmeter-ammeter body 5 at the bottom of the worktable 1, and with the detection end of the voltmeter-ammeter body 5 flush with the top surface of the worktable 1, the magnetic core can be removed from the table. The volt-ampere test can be performed by pushing the magnetic core one by one without having to pick it up. The magnetic core is placed inside the U-shaped limiting frame 6, and then the motor 9 is started via the PLC controller 20. The motor 9 drives the drive block 10 to move to the position of the magnetic core via the lead screw 11. At this time, the end of the L-shaped sliding plate 14 away from the drive block 10 slides inside the slide groove 15. Then, the PLC controller 20 starts the cylinder 12, which drives the U-shaped picking plate 13 to move towards the magnetic core until the entire magnetic core is completely inserted into the U-shaped picking plate 13. The motor 9 is then started again via the PLC controller 20, and the motor 9 drives the drive block 10 via the lead screw 11. The drive block 10 moves towards the detection slot 2, and the drive block 10 drives the magnetic core to slide inside the U-shaped limit frame 6 through the U-shaped material picking plate 13 until the magnetic core moves to the top of the detection slot 2. Finally, it is tested through the test end of the volt-ampere tester body 5, which realizes the function of improving the test speed. This solves the problem that common volt-ampere test fixtures only contain the test function and can test the magnetic core, but lack the function of improving the test speed. They cannot guarantee the test speed and are prone to problems such as inconvenient and slow operation due to the complicated structure of the volt-ampere test fixture, especially new employees who find it difficult to get started, which affects the test speed.
[0024] Please see Figures 2-5In this embodiment, the lead screw 11 is threadedly connected to the drive block 10. The left end of the lead screw 11 is rotatably connected to the left side plate 7, and the right end of the lead screw 11 passes through the right side plate 8 and is connected to the output end of the motor 9. The motor 9 can drive the lead screw 11 to rotate in the forward or reverse direction. A U-shaped limiting frame 6 is set on the left side of the top middle of the workbench 1, corresponding to the position of the detection slot 2. The U-shaped picking plate 13 is located on the top of the U-shaped limiting frame 6. The cylinder 12 drives the U-shaped picking plate 13 to move towards the magnetic core until the entire magnetic core is completely inserted into the interior of the U-shaped picking plate 13. Two L-shaped sliding plates 14 are symmetrically arranged on the front and rear sides of the drive block 10. Two sliding grooves 15 are opened on the top of the workbench 1, corresponding to the positions of the two L-shaped sliding plates 14. The end of the L-shaped sliding plate 14 away from the drive block 10 is inserted into the interior of the sliding groove 15. The end of the L-shaped sliding plate 14 away from the drive block 10 can slide inside the sliding groove 15.
[0025] Please see Figures 1-5 In this embodiment, four support legs 16 are provided at the four corners of the bottom of the workbench 1. A connecting frame 17 is provided at the right end of the rear side of the workbench 1, corresponding to the position of the detection groove 2. The position of the storage box 18 is defined by the connecting frame 17. The storage box 18 is provided inside the connecting frame 17. Hooks 19 are symmetrically provided on the left and right sides of the top of the storage box 18. The storage box 18 is fixed to the connecting frame 17 by the hooks 19. The storage box 18 is hooked on the connecting frame 17 by the hooks 19. A PLC controller 20 is provided at the rear end of the top left side of the workbench 1. The PLC controller 20 controls the start and stop of each component.
[0026] During operation, the voltmeter-ampere detector body 5 is installed on the bottom of the workbench 1, with its detection end flush with the top surface of the workbench. The magnetic core can be directly pushed into the test area along the table without manual handling. During operation, after the magnetic core is guided into the positioning area of the U-shaped limit frame 6, the PLC controller 20 triggers the motor 9 to operate, which drives the drive block 10 to move to the corresponding position of the magnetic core via the lead screw 11. At this time, the end of the L-shaped sliding plate 14 slides and positions synchronously within the slide groove 15. Subsequently, the PLC controller 20 activates the cylinder 12, pushing the U-shaped material picking plate 13 to precisely approach the magnetic core until the magnetic core is completely embedded. The clamping structure of the U-shaped material picking plate 13 is used. Finally, the PLC controller 20 starts the motor 9 for the second time. The drive block 10 drives the U-shaped material picking plate 13 and the magnetic core to slide along the U-shaped limit frame 6 to the top of the detection slot 2 via the lead screw 11. The automatic detection is completed by the test end of the volt-ampere detector body 5. After the magnetic core is detected, the PLC controller 20 activates the cylinder 12 again. The cylinder 12 continues to push the magnetic core to the position of the storage box 18 through the U-shaped material picking plate 13 until the magnetic core falls into the storage box 18 for storage. The testing efficiency is improved through mechanical linkage and programmed control.
[0027] Through the above steps, by placing the voltmeter-ampere detector body 5 at the bottom of the workbench 1, with the detection end of the voltmeter-ampere detector body 5 flush with the top surface of the workbench 1, the magnetic cores can be pushed over one by one from the table for voltmeter-ampere testing without having to pick them up. The magnetic core is placed inside the U-shaped limiting frame 6, and then the PLC controller 20 starts the motor 9. The motor 9 drives the drive block 10 to move to the position of the magnetic core via the lead screw 11. At this time, the end of the L-shaped sliding plate 14 away from the drive block 10 slides inside the slide groove 15. Then, the PLC controller 20 starts the cylinder 12, which drives the U-shaped picking plate 13 to move towards the magnetic core until the entire magnetic core is completely inserted into the U-shaped picking plate 13. The motor 9 is restarted by the PLC controller 20. The motor 9 drives the drive block 10 to move to the position of the detection slot 2 through the lead screw 11. The drive block 10 then drives the magnetic core to slide inside the U-shaped limit frame 6 through the U-shaped material pick-up plate 13 until the magnetic core moves to the top of the detection slot 2. Finally, the test is performed through the test end of the volt-ampere tester body 5. This realizes the function of improving the test speed, so as to solve the problem that common volt-ampere test fixtures only contain the test function and can test the magnetic core, but lack the function of improving the test speed. They cannot guarantee the test speed and are prone to problems such as inconvenient and slow operation due to the cumbersome structure of the volt-ampere test fixture, especially new employees who find it difficult to get started, which affects the test speed.
