[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] like Figures 1 to 3 As shown, a creep testing device according to an embodiment of the present invention includes a high and low temperature test chamber 1, a sample library 2, a clamping fixture 3, a first robotic arm 4, and a second robotic arm 5. The high and low temperature test chamber 1 has a test chamber 101. The sample library 2 is used to load samples to be tested and samples that have been tested, and the sample library 2 is connected to the test chamber 101. There are multiple clamping fixtures 3, which are spaced apart in the test chamber 101 and are used to clamp the samples. The first robotic arm 4 is connected to the test chamber 101 and is used to clamp and release the samples by the clamping fixtures 3. The second robotic arm 5 is connected to the test chamber 101 and is used to transfer the samples to be tested in the sample library 2 to the clamping fixtures 3 and to transfer the samples that have been tested on the clamping fixtures 3 to the sample library 2.

[0032] In practical applications, the sample library 2 contains the samples to be tested. When testing the samples, the second robotic arm 5 transfers the samples to be tested onto the clamping fixture 3, and then the first robotic arm 4 operates the clamping fixture 3 to clamp the samples. Based on this, the samples undergo creep testing. After the samples complete the creep test, the first robotic arm 4 operates the clamping fixture 3 to release the samples, and then the second robotic arm 5 transfers the samples to be tested back into the sample library 2. Each clamping fixture 3 loads and releases samples through the above process to allow the samples to undergo creep testing. Based on the above process, after the samples complete the creep test, the experimenter only needs to manually remove the samples from the sample library 2, without manually loading the samples onto the clamping fixture 3, which saves operation time, has little impact on the temperature inside the test chamber, and thus reduces the impact on other samples. The creep testing device has the characteristics of high testing accuracy.

[0033] It should be noted that the high and low temperature test chamber 1 includes a chamber body and a door, which are connected to form a test chamber 101. The door can be opened. The high and low temperature test chamber 1 is existing technology and serves to simulate high and low temperature environments, so that the test chamber 101 forms the temperature environment required for the test. This application will not elaborate on this further.

[0034] In this embodiment, the sample storage 2 includes a sample delivery box 21 and a sample receiving box 22. The sample delivery box 21 is connected to one end of the high and low temperature test chamber 1 in the first direction X, and the sample delivery box 21 is located inside the test chamber 101. The sample delivery box 21 is used to load the sample to be tested. The sample receiving box 22 is connected to one end of the high and low temperature test chamber 1 in the first direction X, and the sample receiving box 22 is located inside the test chamber 101. The sample receiving box 22 is used to load the sample after testing. With this structure, the sample to be tested and the sample after testing are placed separately, which is easy to identify and facilitates the operation of the experimenter to take out the sample after testing. Moreover, the experimenter will not affect the second robot arm 5 from transferring the sample to be tested onto the clamping fixture 3 during the process of taking out the sample, which is beneficial to improving work efficiency.

[0035] It should be noted that both the sample delivery box 21 and the sample receiving box 22 are made of high and low temperature resistant materials to ensure that the creep testing device can successfully complete the creep test.

[0036] like Figure 2 As shown, along the first direction X, one end of the test chamber is provided with a sample delivery port 102, which is connected to the test chamber 101. The sample delivery box 21 is slidably connected to the high and low temperature test chamber 1, and the sample delivery box 21 seals the sample delivery port 102. The sample delivery box 21 can slide along the first direction X to be extracted from the test chamber 101. The sample delivery box 21 is connected to the high and low temperature sample chamber in this way. Its structure is simple, which makes it easy for the experimenter to place the sample to be tested into the sample delivery box 21. During the placement process, the high and low temperature test chamber does not need to open the chamber door to place the sample to be tested. The opening degree of the test chamber 101 is relatively small, which helps to reduce the influence on the temperature inside the test chamber, thereby ensuring the testing accuracy of other samples and improving the testing accuracy of the creep testing device.

[0037] like Figure 2As shown, the sample delivery box 21 includes a box body 211 and a support plate 212. The box body 211 is slidably connected to the high and low temperature test chamber 1, and the support plate 212 is detachably connected to the box body 211. Multiple support grooves 210 are formed on the support plate 212, which are used to support the sample. This type of sample delivery box 21 has a simple structure. The support grooves 210 allow the sample to be placed stably, facilitating the removal of the sample by the second robotic arm 5. Furthermore, the support plate 212 is detachably connected to the box body 211. When the support plate 212... After all the samples on 12 have been transferred by the second robotic arm 5, the experimenter can load the new test samples onto the main body 211 of the box by changing the support plate 212, completing the reloading work in one go. There is no need to load the test samples into the sample delivery box 21 one by one. The operation is simple and convenient, and it can also reduce the extraction time of the sample delivery box 21, thereby reducing the opening time of the test chamber 101. This helps to reduce the impact on the temperature inside the test chamber, thus ensuring the testing accuracy of other samples and improving the testing accuracy of the creep testing device.

[0038] like Figure 2 As shown, along the first direction X, one end of the test chamber is provided with a sample receiving port 103, which is connected to the test chamber 101. The sample receiving box 22 is slidably connected to the high and low temperature test chamber 1, and the sample receiving box 22 seals the sample receiving port 103. The sample receiving box 22 can slide along the first direction X to be extracted from the test chamber 101. Similarly, the sample receiving box 22 is connected to the high and low temperature sample chamber in this way. Its structure is simple, which makes it easy for the experimenter to take out the tested sample from the test chamber 101. During the removal process, the high and low temperature test chamber does not need to open the chamber door for the experimenter to take out the sample. The opening degree of the test chamber 101 is relatively small, which helps to reduce the influence on the temperature inside the test chamber, thereby ensuring the testing accuracy of other samples and improving the testing accuracy of the creep testing device.

[0039] like Figure 1 As shown, multiple clamping fixtures 3 are spaced apart along the first direction X; the creep testing device also includes a first drive rail 6, which is connected to the test chamber 101. The length of the first drive rail 6 extends along the first direction X. The first drive rail 6 is connected to the first robot arm 4. The first drive rail 6 is used to drive the first robot arm 4 to move along the first direction X. The arrangement of the first drive rail 6 allows the first robot arm 4 to have a large range of motion, which facilitates the operation of the first robot arm 4.

[0040] The creep testing device also includes a second drive rail 7, which is connected to the test chamber 101. The length of the second drive rail 7 extends along the first direction X. The second drive rail 7 is connected to the second robot arm 5. The second drive rail 7 is used to drive the second robot arm 5 to move along the first direction X. The setting of the second drive rail 7 allows the second robot arm 5 to have a larger range of motion, which is convenient for the operation of the second robot arm 5.

[0041] The first drive rail 6 is located above the second drive rail 7. Correspondingly, the first robotic arm 4 and the second robotic arm 5 are arranged vertically, with a reasonable layout. The first robotic arm 4 and the second robotic arm 5 have a large range of motion, and they will not interfere with each other during operation, ensuring that the first robotic arm 4 and the second robotic arm 5 can complete their work smoothly.

[0042] Furthermore, to ensure that the first and second robotic arms can operate normally under high and low temperatures, the creep testing device also includes protective suits. Both the first robotic arm 4 and the second robotic arm 5 are covered with protective suits. The purpose of the protective suits is to isolate the first robotic arm 4 and the second robotic arm 5 from the surrounding environment and reduce the impact of high and low temperatures on the first robotic arm 4 and the second robotic arm 5. Specifically, the protective suits consist of multiple parts, with each arm of the first robotic arm 4 and the second robotic arm 5 covered by a part of the protective suit to avoid affecting the mobility of the first robotic arm 4 and the second robotic arm 5.

[0043] To better reduce the impact of high temperatures on the normal operation of the first robotic arm 4 and the second robotic arm 5, preferably, the first robotic arm and the second robotic arm are equipped with temperature control components, such as temperature control pipes. The creep testing device also includes a cooling cabinet 9, which is connected to the temperature control components. The cooling cabinet 9 is used to prepare a cooling medium and delivers the cooling medium to the temperature control components. The cooling medium removes the temperature of the first robotic arm 4 and the second robotic arm 5, preventing them from overheating for a long time and ensuring that the first robotic arm and the second robotic arm can operate normally.

[0044] In this embodiment, the clamping fixture 3 includes a first clamp 31 and a second clamp 32, which are spaced apart. The first clamp 31 is located above the second clamp 32 and is connected to the upper inner wall of the high and low temperature test chamber 1, and is located on the side of the first drive guide rail 6 perpendicular to the first direction X. The second clamp 32 is connected to the lower inner wall of the high and low temperature test chamber 1 and is located on the side of the second drive guide rail 7 perpendicular to the first direction X. A clamping space is formed between the first clamp 31 and the second clamp 32. The first clamp 31 and the second clamp 32 cooperate to clamp the sample. The structure is simple and easy to install. Specifically, the first clamp 31 and the second clamp 32 are connected to the sample by screws. At this time, the first robot 4 is a tightening robot, which is equipped with a screw tightening tool. The clamping and loosening of the sample is achieved by tightening and loosening the screws. The second robotic arm 5 is a gripping robotic arm. For example, the second robotic arm 5 is equipped with grippers, which carry the sample.

[0045] In this embodiment, the creep testing device also includes a control system 8, wherein the first robotic arm 4, the second robotic arm 5, the first drive rail 6, the second drive rail 7 and the cooling cabinet 9 are all electrically connected to the control system 8. The control system 8 controls the operation of the first robotic arm 4, the second robotic arm 5, the first drive rail 6, the second drive rail 7 and the cooling cabinet 9 based on a preset program or through manual operation. This is prior art, and this application will not elaborate further on it.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
