Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, and more specifically, to a clamping structure for testing PTC products for new energy vehicles. Background Technology

[0002] PTC stands for Positive Temperature Coefficient, generally referring to semiconductor materials or components with a large positive temperature coefficient. Usually, when we mention PTC, we mean Positive Temperature Coefficient Thermistor, or PTC thermistor for short. A PTC thermistor is a typical temperature-sensitive semiconductor resistor. When the temperature exceeds a certain level (Curie temperature), its resistance increases stepwise with the increase of temperature. When testing PTC products for new energy vehicles, PTC products are usually clamped with fixtures.

[0003] Each inspection process requires clamping and releasing the fixture one by one. Most existing fixtures can only clamp one workpiece at a time, resulting in low product clamping and inspection efficiency. Furthermore, traditional clamping mechanisms may cause uneven force due to unilateral drive, affecting inspection accuracy or damaging the product. Traditional clamping devices are complex to install and require repeated alignment adjustments, affecting inspection efficiency. Disassembly of traditional structures requires tools or complex operations, resulting in high maintenance costs and inconvenience. Utility Model Content

[0029] Please see Figures 1-5 A clamping structure for testing PTC products in new energy vehicles includes a support base 1, on which an installation device and a clamping device are provided. The clamping device includes a clamping frame 2 and a driving device. A clamping disc 3 is symmetrically rotatably mounted on the clamping frame 2, and a clamping rod 4 is mounted on the clamping disc 3. A clamping plate 5 is rotatably mounted on the clamping rod 4. A rotating rod 6 is hinged between the clamping plate 5 and the clamping frame 2. The installation device includes an installation sleeve 7, which is mounted on the support base 1. The installation sleeve 7 has a snap-fit ​​groove 8, and a snap-fit ​​groove 8 contains a... The device includes a snap-fit ​​block 9 and a snap-fit ​​spring 30. The clamping frame 2 is provided with an installation rod 10, which has a snap-fit ​​hole 11 that mates with the snap-fit ​​block 9. The installation sleeve 7 is provided with a compression plate 12 and a compression spring 13. The driving device includes a drive motor 14, whose motor shaft is fixedly connected to one of the clamping discs 3. Drive gears 15 are installed on the two clamping plates 5. The clamping plates 5 are provided with a fixing plate 27, which has multiple fixing grooves 28. Rubber pads 29 are provided in the fixing grooves 28.

[0030] In this embodiment, during use, the clamping device is installed on the support base 1 via the mounting device, and the same model of product is placed in the fixing groove 28 of the fixing plate 27. The drive motor 14 is started, and the drive motor 14 drives the clamping disk 3 to rotate. The clamping disk 3 rotates synchronously through the cooperation of the drive gear 15. The clamping disk 3 drives the clamping rod 4 to cooperate with the rotating rod 6, thereby driving the clamping plate 5 and the fixing plate 27 to clamp. The rubber pad 29 improves the clamping stability and prevents the clamping plate 5 from damaging the PCT product.

[0031] Please see Figures 4-5 As one embodiment of the installation device: the installation sleeve 7 is provided with a reset groove 16, a reset block 17 is slidably provided on the reset groove 16, the reset block 17 is provided with an inclined groove 18, a snap-fit ​​rod 19 is provided on one side of the snap-fit ​​block 9, a snap-fit ​​sliding rod 20 that cooperates with the inclined groove 18 is provided on one side of the snap-fit ​​rod 19, a reset spring 21 is provided between the reset groove 16 and the reset block 17, a reset rod 22 is connected to one side of the reset block 17, a reset plate 23 and a reset handle 24 are provided between the reset rods 22, a limit block 25 is provided inside the installation sleeve 7, and a limit groove 26 that cooperates with the limit rod is provided on the installation rod 10.

[0032] More specifically, during installation, the mounting rod 10 of the clamping device is inserted into the mounting sleeve 7 of the support base 1. The mounting rod 10 presses against the locking block 9, and the locking block 9 presses against the locking spring 30. When the locking block 9 is aligned with the locking hole 11, the locking block 9 extends into the locking hole 11. At the same time, the mounting rod 10 pushes the pressing plate 12 and the pressing spring 13. The elastic force of the pressing spring 13 makes the locking block 9 tightly connected to the locking hole 11. When it is necessary to disassemble and maintain the clamping device, it can be... The reset handle 24 lifts the reset plate 23 and the reset rod 22. The reset rod 22 drives the reset block 17 to squeeze the reset spring 21. Through the cooperation of the reset block 17 with the inclined groove 18 and the locking slide rod 20, the locking rod 19 and the locking block 9 move towards the reset groove 16 and compress the locking spring 30, so that the locking block 9 leaves the locking hole 11. The clamping device can then be removed for maintenance. Subsequently, the locking block 9 is reset by the elastic force of the reset spring 21 and the locking spring 30.

[0033] In summary, during the use or operation of the overall equipment: When in use, the clamping device is installed on the support base 1 through the mounting device, and the same model of product is placed in the fixing groove 28 of the fixing plate 27. The drive motor 14 is started, and the drive motor 14 drives the clamping disk 3 to rotate. The clamping disk 3 rotates synchronously through the cooperation of the drive gear 15. The clamping disk 3 drives the clamping rod 4 to cooperate with the rotating rod 6, thereby driving the clamping plate 5 and the fixing plate 27 to clamp. The rubber pad 29 improves the clamping stability and prevents the clamping plate 5 from damaging the PCT product.

[0034] During installation, the mounting rod 10 of the clamping device is inserted into the mounting sleeve 7 of the support base 1. The mounting rod 10 presses against the snap-fit ​​block 9, and the snap-fit ​​block 9 presses against the snap-fit ​​spring 30. When the snap-fit ​​block 9 is aligned with the snap-fit ​​hole 11, the snap-fit ​​block 9 extends into the snap-fit ​​hole 11. At the same time, the mounting rod 10 pushes the pressing plate 12 and the pressing spring 13. The elastic force of the pressing spring 13 makes the snap-fit ​​block 9 tightly connected to the snap-fit ​​hole 11. When the clamping device needs to be disassembled for maintenance, the reset handle 24 lifts the reset plate 23 and the reset rod 22. The reset rod 22 drives the reset block 17 to press against the reset spring 21. Through the cooperation of the reset block 17 with the inclined groove 18 and the snap-fit ​​slide rod 20, the snap-fit ​​rod 19 and the snap-fit ​​block 9 move towards the reset groove 16 and compress the snap-fit ​​spring 30, so that the snap-fit ​​block 9 leaves the snap-fit ​​hole 11. The clamping device can then be removed for maintenance. Afterward, the snap-fit ​​block 9 is reset by the elastic force of the reset spring 21 and the snap-fit ​​spring 30.
