Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-4 This utility model provides a pulse transformer product testing device, including a workbench 1, a support rod 21 fixedly connected to the top of the workbench 1; a support plate 22 fixedly connected to the top of the support rod 21, and a driving device 23 mounted on the top of the support plate 22; a testing device 24 fixedly connected to the end of the driving device 23; a processing and testing table 25 fixedly connected to the top of the workbench 1; a plurality of slots 26 are provided inside the processing and testing table 25; a clamping rod 27 is slidably connected inside the slots 26; a first spring 28 is fixedly connected to the side end of the clamping rod 27, and the other end of the first spring 28... The end is fixed to the inner wall of the slot 26. During operation, when the pulse transformer needs to be tested, the pulse transformer is placed on the surface of the processing test table 25, and then the clamping rod 27 is squeezed, causing the clamping rod 27 to be squeezed and opened to both sides, thereby squeezing the first spring 28 to generate elastic force. When the pulse transformer is placed, the elastic force generated by the first spring 28 pushes the clamping rod 27 to clamp the surface of the pulse transformer for clamping and fixing. Then, the drive device 23 is opened to drive the test device 24 to move to the bottom to test the pulse transformer, which effectively improves the test accuracy of the pulse transformer.

[0026] Furthermore, such as Figure 3As shown, the clamping rod 27 has a guide groove 31 inside; a protective plate 32 is slidably connected inside the guide groove 31; a second spring 34 is fixedly connected to one end of the protective plate 32, and the other end of the second spring 34 is fixedly connected to the inner side wall of the guide groove 31; during operation, when the clamping rod 27 is squeezed and opens to both sides, the protective plate 32 is squeezed, causing the protective plate 32 to retract into the guide groove 31, squeezing the second spring 34 to generate elastic force, and then pushing the protective plate 32 to fit against the surface of the pulse transformer, thereby protecting the surface of the pulse transformer.

[0027] Furthermore, such as Figure 3 As shown, the surface of the processing test bench 25 is provided with heat dissipation holes 36, and there are several holes; a heat dissipation plate 35 is fixed to the bottom of the processing test bench 25; during operation, the heat dissipation plate 35 installed at the bottom of the processing test bench 25 can dissipate heat from the pulse transformer, thereby reducing the risk of the pulse transformer's test accuracy being reduced due to high temperature during the test.

[0028] Furthermore, such as Figures 1-2 As shown, a motor 51 is fixedly connected to the bottom of the workbench 1; a rotating rod 52 is fixedly connected to the output end of the motor 51; and a heat dissipation blade 53 is fixedly connected to the end of the rotating rod 52. During operation, when the temperature of the pulse transformer is high, the motor 51 is turned on to drive the rotating rod 52 and the heat dissipation blade 53 to rotate, thereby blowing air upwards to dissipate heat from the heat dissipation plate 35. The air is also blown onto the surface of the pulse transformer through the heat dissipation holes 36 for rapid cooling.

[0029] Furthermore, such as Figures 1-2 As shown, the protective plate 32 has friction pads 33 at its ends, and there are several of them. During operation, by providing friction pads 33 at the ends of the protective plate 32, the friction between the protective plate 32 and the outer shell of the pulse transformer is increased, thereby reducing the problem of the pulse transformer shifting during the test.

[0030] Furthermore, such as Figures 1-2 As shown, a support leg 41 is fixedly connected to the bottom of the workbench 1; a support pad 42 is fixedly connected to the bottom of the support leg 41; during operation, by installing the support leg 41 and the support pad 42 at the bottom of the workbench 1, the support pad 42 contacts the ground, thereby providing support and stability to the workbench 1.

[0031] Working principle: When testing a pulse transformer, the transformer is placed on the surface of the processing test bench 25. The clamping rod 27 is then squeezed, causing it to open to both sides, compressing the first spring 28 and generating elastic force. Once the pulse transformer is in place, the elastic force of the first spring 28 pushes the clamping rod 27 to clamp the transformer surface for secure clamping. Then, the drive device 23 is activated, moving the testing device 24 to the bottom to perform the pulse transformer test, effectively improving the testing accuracy. When the clamping rod 27 is squeezed and opens to both sides, it compresses the protective plate 32, causing it to retract into the guide groove 31, compressing the second spring 34 and generating elastic force. This pushes the protective plate 32 to adhere to the surface of the pulse transformer, providing protection for its exterior. The following measures are taken: A heat sink 35 is installed at the bottom of the processing test bench 25 to dissipate heat from the pulse transformer, reducing the risk of decreased testing accuracy due to high temperature. When the pulse transformer temperature is high, the motor 51 is turned on to rotate the rotating rod 52 and the heat dissipation blades 53, blowing air upwards to cool the heat sink 35. Air is also blown through the heat dissipation holes 36 onto the surface of the pulse transformer for rapid cooling. Friction pads 33 are provided at the ends of the protective plate 32 to increase the friction between the protective plate 32 and the pulse transformer housing, reducing the risk of displacement during testing. Support legs 41 and support pads 42 are installed at the bottom of the workbench 1, with the support pads 42 contacting the ground to provide support and stability.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
