Description

Technical Field

[0001] This utility model relates to the technical field of plastic testing equipment, specifically to a multi-parameter dynamic testing device for thermally conductive plastics. Background Technology

[0002] The thermal conductivity meter is a key device for measuring the thermal conductivity of plastics. By integrating multi-sensor technology, the thermal conductivity meter can simultaneously monitor multiple physical quantities such as temperature, heat flux density, and sample deformation. The device, which uses infrared thermal imaging and heat flux sensor in combination, can acquire the surface temperature distribution and internal heat flux changes of the sample in real time. Combined with pressure sensor and humidity control module, it can realize dynamic testing of multiple parameters.

[0003] In the existing technology, the thermal conductivity meter requires the probe to be placed between two sets of thermally conductive plastic parts during the test. Then, a clamp is used to press the plastic parts so that the plastic parts hold the probe for testing. However, during operation, the operator needs to manually adjust the position of the two thermally conductive plastic parts to align them, which is cumbersome. Moreover, when pressing the plastic parts, the plastic parts are prone to slippage and displacement between them and the probe, affecting the accuracy of the test results. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a multi-parameter dynamic testing device for thermally conductive plastics, thereby solving the problems mentioned in the background art where the thermal conductivity meter requires manual adjustment of the positions of two thermally conductive plastic parts to align them, and where the plastic parts are prone to sliding and shifting between themselves and the probe when pressing the plastic parts.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A multi-parameter dynamic testing device for thermally conductive plastics, comprising: A thermal conductivity measuring instrument, wherein the thermal conductivity measuring instrument is provided with a connecting line and a probe is provided on the connecting line, characterized in that it further includes; A limiting structure is arranged on the thermal conductivity measuring instrument to adjust and fix the position of the two sets of thermally conductive plastic parts; A support structure, arranged on the limiting structure, is used to support the probe; A rotating structure, arranged on the limiting structure, is used to adjust the angle of the clamping components of the limiting structure.

[0006] Preferably, the limiting structure includes: The mounting base is positioned above the thermal conductivity measuring instrument. U-shaped plate one, arranged above the mounting base; The adjusting screw is threaded inside the mounting base. The guide rod is arranged on one side of the U-shaped plate; U-shaped plate two, which is slidably sleeved on the guide rod and rotatably installed at one end of the adjusting screw; The clamping assembly is arranged inside the mounting base and the second U-shaped plate.

[0007] Preferably, the clamping assembly is arranged in two sets, and each set of clamping assemblies includes: Two U-shaped slide blocks are slidably installed inside U-shaped plate one and U-shaped plate two, respectively; Four clamping plates are symmetrically rotated and mounted on two U-shaped sliding blocks; Two bidirectional lead screws are rotatably installed inside U-shaped plate one and U-shaped plate two, respectively, and the two bidirectional lead screws are threaded into the inside of two U-shaped slides.

[0008] Preferably, the clamping assembly further includes a rubber pad disposed on one side of the clamping plate to increase the friction of clamping.

[0009] Preferably, the support structure includes: The L-shaped skateboard is slidably mounted on top of the U-shaped board. The support sleeve is rotatably mounted on one end of the L-shaped slide plate. The support sleeve is fixedly sleeved on the connecting line and arranged on one side of the probe.

[0010] Preferably, the support structure further includes an adjustment component arranged on the L-shaped slide plate for adjusting the horizontal position of the L-shaped slide plate.

[0011] Preferably, the adjustment component includes: A fixing screw is arranged on one side of the U-shaped plate and slidably installed inside the L-shaped slide plate; Two limit nuts are threaded onto the fixing screw, and the two limit nuts contact the two sides of the L-shaped slide plate respectively.

[0013] The beneficial effects of this utility model are as follows: In this invention, two thermally conductive plastic parts are placed between four corresponding clamping plates. Rotating the bidirectional screw controls the clamping plates to approach and clamp the plastic parts. Then, flipping the support plate causes the probe to contact the surface of one of the plastic parts. Rotating the adjusting screw allows the thermally conductive plastic parts on both sides to clamp the probe in the middle, completing the probe setup for testing. The use of multiple clamping plates enables rapid clamping of the plastic parts while ensuring alignment of the parts on both sides, avoiding misalignment or displacement that would require repeated calibration, thus improving the accuracy of the test results.

[0014] This invention allows the clamping plates to be rotated and adjusted by rotating a knob. The angle of the two clamping plates can be adjusted so that they are perpendicular to each other. This can be used to fit the sides of square plastic parts, or adjusted according to the different sizes of round workpieces, so that the clamping plates can better fit the surface of the plastic parts.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: like Figures 1 to 6 As shown, this utility model provides a multi-parameter dynamic testing device for thermally conductive plastics, including: a thermal conductivity meter 1, a connecting line 101 on the thermal conductivity meter 1, a probe 102 on the connecting line 101, and a limiting structure arranged on the thermal conductivity meter 1 for adjusting and fixing the positions of two sets of thermally conductive plastic parts.

[0020] The limiting structure includes a mounting base 2 arranged above the thermal conductivity measuring instrument 1, a U-shaped plate 201 arranged above the mounting base 2, an adjusting screw 206 threaded inside the mounting base 2, a guide rod 207 arranged on one side of the U-shaped plate 201, a U-shaped plate 208 slidably sleeved on the guide rod 207 and rotatably mounted on one end of the adjusting screw 206, and a clamping assembly arranged inside the mounting base 2 and the U-shaped plate 208 for clamping the thermally conductive plastic parts. After the thermally conductive plastic parts are clamped by the clamping assembly, the U-shaped plate 208 can be moved by rotating the adjusting screw 206. The moving U-shaped plate 208 can move the clamped thermally conductive plastic parts closer to the probe 102, so that the two thermally conductive plastic parts can clamp the probe 102 in the middle.

[0021] Specifically, there are two sets of clamping components. Each set of clamping components includes two U-shaped slides 202 that are slidably installed inside U-shaped plate 1 201 and U-shaped plate 208, respectively; four clamping plates 203 that are symmetrically rotatably installed on the two U-shaped slides 202; and two bidirectional lead screws 204 that are rotatably installed inside U-shaped plate 1 201 and U-shaped plate 208, respectively. The two bidirectional lead screws 204 are threaded inside the two U-shaped slides 202. The two thermally conductive plastic parts are respectively arranged between the corresponding two clamping plates 203. Then, rotating the corresponding bidirectional lead screws 204 can drive the two U-shaped slides 202 to slide and move closer to each other, thereby driving the clamping plates 203 on both sides to move closer to each other and clamp onto the thermally conductive plastic parts.

[0022] Specifically, the clamping assembly also includes a rubber pad 205 arranged on one side of the clamping plate 203 to increase the clamping friction. The rubber pad 205 can improve the friction between the clamping plate 203 and the plastic part, thereby improving the clamping stability.

[0023] Example 2: Based on Example 1, in order to quickly adjust the probe 102 to a position close to the center of the thermally conductive plastic part, a support structure for supporting the probe 102 is arranged on the limiting structure.

[0024] The support structure includes an L-shaped slide plate 3 that is slidably mounted on the U-shaped plate 201, and a support sleeve 301 that is rotatably mounted on one end of the L-shaped slide plate 3. The support sleeve 301 is fixedly sleeved on the connecting line 101 and arranged on one side of the probe 102. After the heat-conducting plastic parts on both sides are fixed, the support sleeve 301 is flipped to move the probe 102 to the surface of one of the support sleeves 301. At the same time, the support sleeve 301 is set in the middle position of the clamping component, thereby ensuring that the probe 102 can be located near the middle of the heat-conducting plastic part.

[0025] The support structure also includes an adjustment component arranged on the L-shaped slide plate 3 for adjusting the horizontal position of the L-shaped slide plate 3.

[0026] Specifically, the adjustment assembly includes a fixing screw 302 arranged on one side of the U-shaped plate 201 and slidably installed inside the L-shaped slide plate 3, and two limiting nuts 303 threaded on the fixing screw 302. The two limiting nuts 303 contact the two sides of the L-shaped slide plate 3 respectively. Rotating the two limiting nuts 303 can release them from the compression of the L-shaped slide plate 3. At this time, the L-shaped slide plate 3 can be pushed and pulled to drive the probe 102 to approach the thermally conductive plastic part and contact its surface, so as to adjust the position of the probe 102 according to the thickness of the thermally conductive plastic part.

[0027] Example 3: Based on Embodiment 1, in order to enable the clamping plate 203 to clamp round or square plastic parts of different sizes, a rotating structure for adjusting the angle of the clamping component of the limiting structure is arranged on the limiting structure.

[0028] The rotating structure includes a limiting shaft 4 arranged inside the clamping plate 203, the limiting shaft 4 being rotatably installed inside the U-shaped slide 202, a linkage worm gear 401 fixedly sleeved on the limiting shaft 4, a linkage shaft 402 rotatably installed inside the U-shaped slide 202, a worm 403 fixedly sleeved on the linkage shaft 402 and meshing with the linkage worm gear 401, and a knob 404 arranged at one end of the linkage shaft 402. Rotating the corresponding knob 404 can drive the linkage shaft 402 and the worm 403 to rotate. When the worm 403 rotates, it can drive the limiting shaft 4 to rotate through meshing with the linkage worm gear 401, thereby driving the clamping plate 203 to flip and change its angle, ensuring that the clamping plate 203 fits the surface of the plastic part when clamping, so as to adapt to plastic parts of various shapes.

[0029] Working principle: In use, first flip the support sleeve 301 to move the connecting wire 101, causing the connecting wire 101 to disengage the probe 102 from between the U-shaped plate 1 201 and the U-shaped plate 208. Then, place the two heat-conducting plastic parts between the corresponding clamping plates 203. Next, rotate the corresponding bidirectional lead screw 204. The two ends of the bidirectional lead screw 204 have threads facing opposite directions, and these threads are adapted to the two U-shaped slides 202, allowing the rotating bidirectional lead screw 204 to drive the two U-shaped slides 202. 02. Slide within U-shaped plate 1 201 or U-shaped plate 208 and bring them closer together, thereby causing the clamping plates 203 on both sides to move closer together, so that the rubber pad 205 is clamped on the thermally conductive plastic part, and the thermally conductive plastic part is located in the middle of the four clamping plates 203, so as to quickly align and position the thermally conductive plastic parts on both sides, and fix the position of the thermally conductive plastic parts. After fixing the thermally conductive plastic parts on both sides, flip the support sleeve 301 again to drive the probe 102 to reset and be located on the surface of one of the support sleeves 301, in a position. Figure 1 and Figure 2In this configuration, the support sleeve 301 assists in supporting the connecting wire 101 and the probe 102. Simultaneously, the support sleeve 301 is positioned in the middle of the clamping component, ensuring that the probe 102 is located near the center of the thermally conductive plastic part, eliminating the need for manual adjustment. Rotating the two limiting nuts 303 allows them to move through their threaded engagement with the fixing screw 302, releasing the limiting nuts 303 from the pressure on the L-shaped sliding plate 3. At this point, the L-shaped sliding plate 3 can be pushed and pulled to adjust the position of the support sleeve 301, enabling... The movable probe 102 is brought close to and in contact with the thermally conductive plastic part so that the position of the probe 102 can be adjusted according to the thickness of the thermally conductive plastic part. Then, the adjusting screw 206 is rotated. The adjusting screw 206 can move by thread engagement with the mounting base 2, thereby driving the U-shaped plate 208 to move accordingly. The moving U-shaped plate 208 can slide on the guide rod 207, and at the same time, it drives the clamped thermally conductive plastic part to move closer to the probe 102, so that the two thermally conductive plastic parts can clamp the probe 102 in the middle, so as to detect the thermal conductivity of the thermally conductive plastic part.

[0030] Rotating the corresponding knob 404 can drive the linkage shaft 402 to rotate, which in turn drives the worm gear 403 to rotate. When the worm gear 403 rotates, it can drive the limit shaft 4 to rotate through meshing with the linkage worm wheel 401. The limit shaft 4 can drive the clamping plate 203 to flip, thereby changing the angle of the clamping plate 203. The angles of the two clamping plates 203 can be adjusted to make them perpendicular to each other. When clamping a square thermally conductive plastic part, the two perpendicularly angled clamping plates 203 can clamp the two sides of the square thermally conductive plastic part, thus making it suitable for both square and round thermally conductive plastic parts. The knob 404 can be set with a scale to observe the rotation angle.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
