Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature detection auxiliary equipment technology, and specifically to a platform for detecting temperature changes. Background Technology
[0002] In fields such as materials research and development and reliability testing of electronic equipment, temperature change detection (e.g., high and low temperature cycling from -40℃ to 150℃, temperature gradient testing) is a crucial step in verifying sample performance. The stage, as a core auxiliary device for sample support and fixation, directly impacts the accuracy of the test data due to its stability and adjustability. Currently, most temperature change detection stages on the market employ traditional structural designs, which struggle to meet the core requirements of stable clamping, precise adjustment, versatility, and convenient operation. Specific problems include: Traditional stages only have a load-bearing function and no angle adjustment capability, which cannot simulate the temperature detection requirements of the actual installation posture of the sample (such as tilted state); a few devices with angle adjustment have unreasonable linkage design between the angle adjustment and the lifting structure, which can easily interfere with the carrier plate and clamping components when rotating, and the adjustment accuracy is low, making it difficult to meet the requirements of high-precision detection. Utility Model Content
[0003] This invention addresses the problems of existing technologies by providing a platform for detecting temperature changes.
[0004] The objective of this utility model can be achieved through the following technical solution: A platform for temperature change detection includes a support frame and a fixing mechanism on the support frame. The fixing mechanism includes a clamping module and a lifting module. The clamping module includes a gear box located in the middle of the support frame, threaded rods rotatably mounted at both ends of the gear box, a drive motor connected to the gear box, and a clamping assembly mounted on the threaded rods. The clamping assembly includes a clamping frame, a connecting seat located at the bottom of the clamping frame, guide seats located at both ends of the clamping frame, a steering motor located inside the clamping frame, and a clamping plate. The connecting seat is threadedly connected to the threaded rods. A rotating base is provided on the side end of the clamping plate. The rotating base is connected to the output end of the steering motor. Guide rods are provided at both ends of the support frame. The guide seats are slidably mounted on the guide rods. The lifting module includes a lifting cylinder located at the upper end of the gear box and a carrying plate located at the upper end of the lifting cylinder.
[0005] In a further improvement, the clamping plate includes a clamping plate one, a clamping plate two, a sliding rod, and a buffer spring. One end of the clamping plate one is fixedly connected to the rotating end of the rotating base, and the other end is fixedly provided with a sliding rod. The clamping plate two is slidably sleeved on the sliding rod, and a limiting ring is provided at the end of the sliding rod. The buffer spring is sleeved on the sliding rod, and its two ends abut against the opposing surfaces of the clamping plate one and the clamping plate two, respectively.
[0006] As a further improvement, a rubber pad is provided on the side of the clamping plate two away from the clamping plate one, and the surface of the rubber pad is provided with anti-slip texture.
[0007] As a further improvement, the lower end of the support frame is provided with pads, which are made of elastic rubber.
[0008] Compared with the prior art, the present invention has the following beneficial effects: 1. The clamping module of this utility model realizes the synchronous counter-rotation of two sets of threaded rods through gearbox transmission, which drives the clamping components to move towards each other. The clamping force is evenly distributed, effectively preventing the sample from shifting horizontally when the temperature changes or the equipment vibrates, providing a stable benchmark for testing. The sliding fit between the guide seat and the guide rod restricts the rotation of the clamping frame, ensuring smooth translation of the clamping components without jamming. The clamping plate is made of non-slip rubber material, which not only enhances the friction with the sample to improve the fixing effect, but also avoids hard contact that scratches the sample surface, protecting the integrity of the sample to be tested. 2. The lifting module of this utility model works independently without the need for a linkage clamping structure. The lifting stroke of the carrier plate is controlled by the lifting cylinder, which can quickly adapt to the height requirements of different testing equipment such as high and low temperature chambers and temperature sensors. There is no need to adjust the entire platform, making it easy to operate. When adjusting the angle, the sample is first fixed by the clamping component, and then the carrier plate is lowered to detach from the sample, thus avoiding rotational interference from the source. The steering motor is equipped with an angle encoder, which can achieve angle adjustment with an accuracy of ±0.5° within the range of 0°~180°. It can simulate the actual installation posture of the sample and meet the needs of multi-directional temperature change detection. 3. The spacing of the clamping assembly of this utility model can be flexibly adjusted by rotating the threaded rod, and with the interchangeable carrier plates of different sizes, it is suitable for samples of different sizes, thus improving the applicability of the equipment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0013] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.
[0014] Example 1 A platform for temperature change detection includes a support frame 1 and a fixing mechanism 2 mounted on the support frame 1. The fixing mechanism 2 includes a clamping module 3 and a lifting module 4. The clamping module 3 includes a gear box 31 located in the middle of the support frame 1, threaded rods 32 rotatably mounted at both ends of the gear box 31, a drive motor 33 connected to the gear box 31, and a clamping assembly 34 mounted on the threaded rods 32. The clamping assembly 34 includes a clamping frame 341, a connecting seat 342 located at the bottom end of the clamping frame 341, and clamping components located at both ends of the clamping frame 341. The support frame 1 includes a guide seat 343, a steering motor 344 located inside the clamping frame 341, and a clamping plate 345. The connecting seat 342 is threadedly connected to the threaded rod 32. The clamping plate 345 has a rotating base 3451 on its side end, which is connected to the output end of the steering motor 344. The support frame 1 has guide rods 11 at both ends, and the guide seat 343 is slidably mounted on the guide rods 11. The lifting module 4 includes a lifting cylinder 41 located at the upper end of the gear box 31 and a carrying plate 42 located at the upper end of the lifting cylinder 41.
[0015] like Figures 1-4 As shown, this utility model includes a support frame 1 and a fixing mechanism 2. The fixing mechanism 2 consists of a clamping module 3 and a lifting module 4. The three work together to achieve stable clamping, height adjustment and angle fine adjustment of the sample. The support frame 1 is the overall bearing base and provides stable support. The clamping module 3 is used to clamp and fix the sample from both sides to prevent the sample from shifting during temperature changes and to adjust the angle of the sample. The lifting module 4 is used to adjust the height of the sample to adapt to the detection height requirements of different temperature detection equipment.
[0016] Specifically, the gearbox 31 in the clamping module 3 is fixed in the middle of the support frame 1 and has a bevel gear transmission structure inside, which is used to transmit the power of the drive motor 33 and realize the synchronous reverse rotation of the two sets of threaded rods 32. Two sets of threaded rods 32 are symmetrically rotated and assembled at both ends of the gear box 31. The surface of the rod body is a trapezoidal thread. The threads of the two sets of threaded rods 32 have opposite directions to ensure that the clamping assembly 34 moves synchronously towards or in opposite directions. The drive motor 33 is fixed to the side of the gear box 31 by a bracket, and the output end is connected to the bevel gear inside the gear box 31. The motor is equipped with a frequency converter, which can adjust the speed to control the moving speed of the clamping assembly 34 and avoid damaging the sample. Two sets of clamping assemblies 34 are symmetrically assembled on the threaded rod 32, including: The clamp 341 is made of lightweight alloy and provides a mounting carrier for internal components; The connecting seat 342 is fixed to the bottom end of the clamping frame 341, and has a threaded hole inside that is adapted to the threaded rod 32. The assembly with the threaded rod 32 is achieved through threaded connection. The guide seat 343 is located at both ends of the clamping frame 341, and has a guide hole inside. It is slidably sleeved on the guide rod 11 to restrict the rotation of the clamping frame 341 and ensure stable translation. The steering motor 344 is fixed inside the clamping frame 341, and its output end passes through the inner wall of the clamping frame. The clamping plate 345 is made of wear-resistant and non-slip rubber material (to avoid scratching the sample and enhance friction). The rotating base 3451 fixed on the side is connected to the output end of the steering motor 344 through a coupling, which can realize the angle rotation adjustment.
[0017] Lifting Module 4 The lifting cylinder 41 is vertically fixed to the upper end of the gear box 31, with the piston rod facing upward. The cylinder stroke can be adjusted according to the detection requirements. It is equipped with a pressure sensor to avoid excessive lifting and lowering that could cause sample collision. The carrier plate 42 is a rectangular metal plate with a high-temperature resistant silicone pad that can be attached to its surface. It is fixed to the top of the piston rod of the lifting cylinder 41 and is used to support the sample to be tested. Different sizes of carrier plates can be replaced as needed.
[0018] During the use of this utility model: First, place the sample to be tested stably on the silicone pad of the carrier plate 42, ensuring that the center of the sample is aligned with the center of the carrier plate 42 to avoid shifting the center of gravity; When adjusting the height, only the lifting module 4 works independently. The lifting cylinder 41 is activated, and the piston rod extends and retracts to lift the carrier plate 42 and the sample. The height is adjusted to the target height that is compatible with the temperature detection equipment (such as the detection area of the high and low temperature chamber). The cylinder is then locked in place, and the clamping module 3 is not required. When adjusting the angle, the sample is first clamped and fixed by the clamping assembly 34. The drive motor 33 is powered on, and the clamping speed is set. The drive motor 33 drives two sets of threaded rods 32 to rotate synchronously in opposite directions via the gearbox 31. The connecting seat 342, threaded to the threaded rods 32, drives the clamping assembly 34 to move towards each other along the guide rod 11. When the clamping plates 345 on both sides are in contact with the sample side, the drive motor 33 automatically stops (this can be triggered by a pressure sensor), completing the lateral clamping and fixing of the sample. Then, the lifting cylinder 41 is activated to lower the carrier plate 42, disengaging it from the sample bottom to avoid rotational interference. Next, the steering motor 344 is activated, driving the clamping plate 345 and the sample to rotate synchronously via a coupling (transmission component) and the rotating base 3451. The angle can be adjusted to any target angle within 0° to 180° according to the testing requirements. After adjustment, the steering motor 344 is turned off to lock the angle. If height adjustment is needed, the lifting cylinder 41 can be activated again to reset the carrier plate 42 to support the sample.
[0019] Finally, during the testing process, temperature change detection is carried out according to the preset procedure. After the test is completed, the temperature is allowed to return to room temperature. The temperature detection device is then turned on. The lifting cylinder 41 is used to adjust the support plate 42 to support the sample. Then the drive motor 33 is released, causing the clamping component 34 to move in the opposite direction to detach from the sample. The tested sample is then removed.
[0020] This utility model has the following beneficial effects: 1. The clamping module 3 achieves synchronous counter-rotation of two sets of threaded rods 32 through the gearbox 31, driving the clamping components 34 to move towards each other. The clamping force is evenly distributed, effectively preventing the sample from shifting horizontally when the temperature changes (thermal expansion and contraction) or the equipment vibrates, providing a stable benchmark for testing. The sliding fit between the guide seat 343 and the guide rod 11 restricts the rotation of the clamping frame 341, ensuring smooth translation of the clamping components 34 without jamming. The clamping plate 345 is made of non-slip rubber material, which not only enhances the friction with the sample to improve the fixing effect, but also avoids hard contact that scratches the sample surface, protecting the integrity of the sample being tested. 2. The lifting module 4 operates independently without the need for a linkage clamping structure. The lifting cylinder 41 controls the lifting stroke of the carrier plate 42, which can quickly adapt to the height requirements of different testing equipment such as high and low temperature chambers and temperature sensors. There is no need to adjust the entire platform, making operation convenient. When adjusting the angle, the sample is first fixed by the clamping component 34, and then the carrier plate 42 is lowered to detach from the sample, avoiding rotational interference from the source. The steering motor 344 is equipped with an angle encoder, which drives the sample to rotate through the rotating base 3451. It can achieve angle adjustment with an accuracy of ±0.5° within the range of 0°~180°, which can simulate the actual installation posture of the sample and meet the needs of multi-directional temperature change detection. 3. The spacing of the clamping components 34 can be flexibly adjusted by rotating the threaded rod 32. With the interchangeable carrier plates 42 of different sizes, it is suitable for samples of different sizes, thus improving the applicability of the equipment.
[0021] As a further preferred embodiment, the clamping plate 345 includes a first clamping plate 51, a second clamping plate 52, a sliding rod 53, and a buffer spring 54. One end of the first clamping plate 51 is fixedly connected to the rotating end of the rotating base 3451, and the other end is fixedly provided with the sliding rod 53. The second clamping plate 52 is slidably sleeved on the sliding rod 53, and the end of the sliding rod 53 is provided with a limiting ring 531. The buffer spring 54 is sleeved on the sliding rod 53, and its two ends abut against the opposing surfaces of the first clamping plate 51 and the second clamping plate 52, respectively.
[0022] Specifically, the buffer spring 54 is sleeved on the sliding rod 53, with its two ends abutting against the clamping plate 51 and the clamping plate 52. During clamping, it can buffer the clamping force through elastic deformation to avoid sample deformation due to excessive clamping. At the same time, it adapts to the small protrusions or irregular contours on the sample surface, improving the clamping fit. The sliding rod 53 provides guidance for the clamping plate 52, ensuring stable translation without deviation during the buffering process. The limiting ring 531 restricts the sliding stroke of the clamping plate 52 to prevent it from disengaging from the sliding rod 53, balancing the buffering effect and structural reliability. Combined with the uniform clamping force of the clamping module 3, it further ensures the sample fixation stability.
[0023] As a further preferred embodiment, a rubber pad 521 is provided on the side of the clamping plate 52 away from the clamping plate 51, and the surface of the rubber pad 521 is provided with anti-slip texture.
[0024] Specifically, the rubber pad 521 of the clamping plate 52 is soft, which avoids hard contact between the clamping plate 52 and the sample, prevents scratching the sample surface, and protects the integrity of the sample. The elasticity of the rubber material can further enhance the clamping fit and adapt to samples of different materials. The anti-slip texture 522 on the surface of the rubber pad 521 increases the friction with the sample, effectively preventing slippage caused by thermal expansion and contraction of the sample or slight vibration of the equipment when the temperature changes. It is especially suitable for samples with smooth surfaces and further improves the reliability of clamping and fixing.
[0025] As a further preferred embodiment, the lower end of the support frame 1 is provided with a foot 12, which is made of elastic rubber.
[0026] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
