[0002] With the continuous development of industrial technology, hollow shafts have been widely used in aerospace, high-speed trains, industrial machinery and other fields. However, hollow shafts may also develop various defects during use, such as cracks, wear and corrosion. These defects can seriously affect their performance and safety. Therefore, hollow shafts need to be inspected and maintained regularly during production.
[0003] In existing technologies, the support mechanism is mainly located at the bottom of the hollow shaft to support it. However, this has certain limitations in practical use. Since the support mechanism only provides support for the hollow shaft during inspection, its function is singular, making it difficult to accurately adjust the inspection position of the hollow shaft. Moreover, it lacks a precise numerical marking structure, which is not conducive to accurately recording the position information of the hollow shaft during the inspection process. This makes it impossible for inspectors to quickly locate specific parts of the hollow shaft, thus affecting subsequent inspection and analysis and reducing inspection efficiency. Therefore, a support mechanism for hollow shaft inspection is proposed to solve the above problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Example: This example provides a support mechanism for hollow shaft testing. See [link to example]. Figure 1-5 Specifically, including:
[0030] The support box 1 and the movable block 2 are provided. The top of the support box 1 has a movable opening 102. A folding rod 201 is fixedly installed on the outer wall of the movable block 2 and is slidably engaged in the movable opening 102. A slider 101 is fixedly installed on the top of the support box 1, and a hollow shaft is movably inserted into the slider 101. In use, the hollow shaft is placed on the movable block 2, and its other end is placed on the slider 101. By pushing the movable block 2 to the right, the hollow shaft is moved to the right, so that the outer wall of the hollow shaft slides to the right along the roller axis on the slider 101, which facilitates the detection of different positions of the hollow shaft. A marking component is provided on the outer wall of the movable block 2. The marking component includes:
[0031] The scale 104 is fixedly installed on the outer wall of the support box 1;
[0032] The indicator block 5 has a fixed block 4 fixedly installed on the outer wall of the movable block 2. The bottom of the fixed block 4 has a sliding opening 401, and the inner wall of the sliding opening 401 is movably engaged with a connecting block 501. The bottom of the connecting block 501 is fixedly connected to the top of the indicator block 5. A marking pen 502 is fixedly installed on the outer wall of the indicator block 5. In use, the hollow shaft is moved by pushing the movable block 2. When the hollow shaft is being tested at a certain point, the movement of the movable block 2 is stopped, and the hollow shaft stops at that point. The value of the scale 104 is used as a reference point. The bottom of the indicator block 5 is aligned with the value of the scale 104 to display the position of the hollow shaft being tested in real time. By pushing the indicator block 5 backward, the marking pen 502 is moved backward, and the marking pen 502 marks the point, which is convenient for subsequent locating of the point. This is conducive to accurately recording the position information of the hollow shaft during the testing process, and helps the testing personnel to quickly locate the specific part of the hollow shaft, so as to conduct more detailed testing and analysis.
[0033] A compression spring 402 is fixedly installed on the inner wall of the slide 401, and the other end of the compression spring 402 is fixedly connected to the connecting block 501. The compression spring 402 pushes the connecting block 501 forward, causing the forward-moving connecting block 501 to drive the indicator block 5 to move forward. The forward-moving indicator block 5 drives the marker pen 502 to move forward, so that the marker pen 502 maintains a certain distance from the support box 1 when not in use, preventing the marker pen 502 from leaving marks on the support box 1 when marking is not needed, thus affecting the recording effect.
[0034] The outer wall of the support box 1 has a groove, and a marking plate 105 is fixedly installed on the inner wall of the groove. The marking pen 502 writes on the marking plate 105. When the mark is not needed, it can be wiped with a sponge cloth for easy cleaning and convenient for subsequent testing of other hollow shafts.
[0035] A support rod 204 is inserted through the outer wall of the movable block 2. A clamping plate 203 is fixedly installed on the outer wall of the support rod 204, and the hollow shaft is movably inserted between the two clamping plates 203. A spring strip 206 is fixedly installed in the inner cavity of the movable block 2, and a stop plate 205 is fixedly installed at the other end of the spring strip 206. The stop plate 205 is fixedly installed on the outer wall of the support rod 204. In use, by placing the hollow shaft to be tested between the two clamping plates 203, the two spring strips 206 push and push, causing the two stop plates 205 to move towards the middle. The two stop plates 205 moving towards the middle then drive the two clamping plates 203 to move towards the middle, thus clamping and fixing the hollow shaft between the two clamping plates 203. This fixes the hollow shaft and prevents it from moving randomly during testing, which would affect the testing position.
[0036] A protective pad 207 is fixedly adhered to the outer wall of the clamping plate 203, which wraps around the outer wall of the hollow shaft, protecting the outer wall of the hollow shaft, reducing the wear of the clamping plate 203 on the outer wall of the hollow shaft, and helping to increase the friction between the clamping plate 203 and the outer wall of the hollow shaft, thereby improving stability.
[0037] The bottom of the movable block 2 is rotatably connected to a roller 208 via a pin, and the top of the support box 1 is provided with a slide groove 103. The bottom of the roller 208 is slidably engaged in the slide groove 103, which facilitates the movement of the movable block 2 and makes it easy to adjust the detection position of the hollow shaft.
[0038] The inner cavity of the support box 1 is rotatably connected to a threaded rod 3 via a bearing, and a movable plate 202 is threadedly connected to the outer wall of the threaded rod 3. The movable plate 202 is fixedly installed at the bottom of the folding rod 201. An adjustment handle 301 is fixedly installed at one end of the threaded rod 3. In use, the user rotates the adjustment handle 301 to drive the threaded rod 3 to rotate, which in turn drives the movable plate 202 and the folding rod 201 to move, thereby driving the movable block 2 to move, which makes it convenient for the user to control and adjust the detection position of the hollow shaft.
[0039] Specifically, the working principle and operation method of this utility model are as follows:
[0040] In use, the hollow shaft to be tested is placed between two sets of clamping plates 203. The compression of two sets of spring bars 206 causes two sets of abutment plates 205 to move towards the center. These abutment plates 205 then move the two sets of clamping plates 203 towards the center, clamping and fixing the hollow shaft between them. This secures the hollow shaft and prevents it from moving arbitrarily during testing, thus preventing it from affecting the testing position. Furthermore, by rotating the adjusting handle 301 clockwise, the threaded rod 3 rotates clockwise, causing the moving plate 202 and the bending rod 201 to move to the right. This, in turn, moves the moving block 2 to the right, which in turn moves the hollow shaft to the right. The outer wall of the hollow shaft slides to the right along the roller axis on the slider 101, which facilitates the detection of different positions of the hollow shaft. When the hollow shaft is being detected at a certain position, the movement of the moving block 2 is stopped, and the hollow shaft stops at that position. The value of the scale 104 is used as a reference point. The bottom of the indicator block 5 is aligned with the value of the scale 104 to display the detection position of the hollow shaft in real time. By pushing the indicator block 5 backward, the marking pen 502 is moved backward, and the marking pen 502 marks the position on the marking plate 105, which is convenient for subsequent retrieval of the position. This is conducive to accurately recording the position information of the hollow shaft during the detection process, and helps the inspectors to quickly locate the specific part of the hollow shaft, so as to carry out more detailed detection and analysis.
[0041] When in use, the user releases the indicator block 5 and pushes the connecting block 501 forward by squeezing the spring 402. The forward-moving connecting block 501 drives the indicator block 5 forward, which in turn drives the marker pen 502 forward. This ensures that the marker pen 502 maintains a certain distance from the marking plate 105 when not in use, preventing the marker pen 502 from leaving marks on the marking plate 105 when marking is not needed, thus affecting the recording effect.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
