[0033] Example
[0034] like Figure 1-4 As shown, the present invention proposes a bidirectional thyristor irradiation fixture, which includes a support rod 1, an alarm 2 for alarming at the top of the support rod 1, a connecting frame 4 for installation and a PLC 3 for comparing data and starting electrical components on the front of the support rod 1, and fixing components 6 for fixing the bidirectional thyristor on both sides of the connecting frame 4.
[0035] The fixing assembly 6 includes a crossbar 601 for adjustment and two cross plates 602 for installation. Rectangular grooves 5 are provided on both sides of the connecting frame 4. The crossbar 601 and the rectangular grooves 5 are movably connected. Limiting grooves are provided on the top and bottom inner walls of the rectangular grooves 5. Limiting strips are provided on the top and bottom of the crossbar 601. The limiting grooves and limiting strips are compatible. A gear 603 for linkage is movably provided between the two cross plates 602. A toothed plate 612 is fixed on one side of the crossbar 601, and the toothed plate 612 meshes with the gear 603. The transmission mechanism includes a disc 604 and a mounting bracket 607 located above one of the horizontal plates 602. Rotating rods are fixed to the top and bottom of the gear 603, with the ends of the two rotating rods movably connected to the two horizontal plates 602 respectively. A connecting shaft is fixed to the bottom of the disc 604, with one end of the connecting shaft passing through the horizontal plate 602 and fixedly connected to one of the connecting shafts. Multiple trapezoidal blocks 605 are fixed to the top of the disc 604, with the adjacent surfaces of trapezoidal blocks 605 and trapezoidal blocks 609 being parallel. The ball bearing 606 and trapezoidal block 609 are fitted together. A connecting rod 608 for limiting is movably mounted on the bracket 607. The bottom end of the connecting rod 608 is equipped with a locking trapezoidal block 609. A second trapezoidal block 605 has multiple ball bearings 606 on the side near the first trapezoidal block 609. The ball bearings 606 can reduce the friction between the first trapezoidal block 609 and the second trapezoidal block 605. Two limiting rods 610 are fixedly mounted on the top of the first trapezoidal block 609. The limiting rods 610 are movably connected to the bracket 607. The connecting rod 606... A spring 611 is fitted on the upper part of the crossbar 601. A rectangular clamping plate 613 for clamping is fixed at one end of the crossbar 601. An arc-shaped clamping plate 615 for clamping is movably provided on one side of the rectangular clamping plate 613. Two slots are provided on one side of the rectangular clamping plate 613. Two blocks 614 are fixed on one side of the arc-shaped clamping plate 615. The blocks 614 and the slots are compatible. Rubber pads are provided on one side of both the rectangular clamping plate 613 and the arc-shaped clamping plate 615. The detachable arc-shaped clamping plate 615 allows the equipment to adapt to clamping materials of different shapes.
[0036] A threaded connecting pipe 616 is fixedly installed on the top of the rectangular clamp 613. The threaded connecting pipe 616 is L-shaped, and a threaded rod 618 is movably installed inside the threaded connecting pipe 616. A temperature sensor 617 is fixedly installed at one end of the threaded rod 618. During the irradiation process, the temperature sensor 617 monitors the temperature change of the bidirectional thyristor in real time and transmits the data to the PLC3. When the temperature exceeds the preset threshold, the PLC3 activates the alarm 2 to issue an alarm, reminding the experimental personnel to take timely cooling measures to avoid damage to the thyristor due to high temperature and ensure the safe conduct of the experiment.
[0037] In this embodiment, the temperature sensor 617 can monitor the temperature of the bidirectional thyristor. The distance between the temperature sensor 617 and the bidirectional thyristor can be controlled by rotating the threaded rod 618, ensuring the accuracy of temperature measurement. During use, the arc-shaped clamping plate 615 is selectively installed according to the shape of the bidirectional thyristor. Then, the bidirectional thyristor is placed between two rectangular clamping plates 613 or the arc-shaped clamping plate 615. Then, the two crossbars 601 are pushed simultaneously. The crossbars 601 drive the toothed plate 612 and the rectangular clamping plate 615. Clamping plate 613 and gear plate 612 drive gear 603, which in turn drives disk 604. Disk 604 drives trapezoidal block 2 605, which presses against trapezoidal block 1 609 on one side. Trapezoidal block 1 609 is pressed upwards and compresses spring 611. When the inclined surface of trapezoidal block 2 605 separates from that of trapezoidal block 1 609, spring 611 causes trapezoidal block 1 609 to reset and lock between the two trapezoidal blocks 2 605, thus achieving control of disk 604. In unidirectional positioning, the crossbar 601 cannot be pulled outward. Once the arc-shaped clamping plate 615 or the rectangular clamping plate 613 is in contact with and fixed to the bidirectional thyristor, the compression of the crossbar 601 can be stopped, and the bidirectional thyristor can be irradiated. During processing, the temperature sensor 617 monitors the temperature change of the bidirectional thyristor in real time and transmits the data to the PLC3. When the temperature exceeds the preset threshold, the PLC3 activates the alarm 2 to sound an alarm, reminding the experimenters to take timely cooling measures to prevent the thyristor from malfunctioning. If the bidirectional thyristor needs to be stopped due to high temperature damage to ensure the safety of the experiment, pull both connecting rods 608 upwards simultaneously. The connecting rods 608 drive the trapezoidal block 609. When the trapezoidal block 609 is no longer in contact with the trapezoidal block 605, pull both horizontal bars 601 in opposite directions. The horizontal bars 601 then drive the rectangular clamping plate 613 or the arc-shaped clamping plate 615. Once the rectangular clamping plate 613 or the arc-shaped clamping plate 615 separates from the material, the bidirectional thyristor can be removed.
[0038] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
