Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, and in particular to a bearing deformation detection device and detection system. Background Technology

[0002] Bearing bushes are key components in sliding bearings, typically made of ductile metals or composite materials, used to support rotating shafts and reduce friction and wear. Ideally, the bearing bush deformation should be controlled within the micrometer range of standard bearing bush dimensions. This ensures effective formation of a lubricating oil film to reduce friction loss, while avoiding excessive vibration due to excessive clearance or abnormal wear caused by insufficient clearance.

[0003] Traditional gap detection methods mostly use feeler gauge measurement or lead pressing method. The measurement accuracy of feeler gauge measurement is greatly affected by the operator's operation, and the deformation of lead wire in lead pressing method is difficult to control accurately. Both methods have low detection efficiency and make it difficult to achieve rapid quantitative detection of bearing deformation. Utility Model Content

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] This utility model provides a bearing deformation detection device, which can solve the technical problem that existing technologies in related fields are unable to achieve rapid quantitative detection of bearing deformation.

[0045] See Figure 1 , Figure 2 and Figure 3 As shown in the figure, this utility model provides a bearing deformation detection device. The detection device includes a base 1, a lower detection block 2, an upper detection block 3, and a measuring tool 4. The lower detection block 2 is disposed on the base 1, and the upper detection block 3 is spaced apart and slidably disposed above the lower detection block 2. The measuring tool 4 is fixed on the upper detection block 3. The shapes of the lower detection block 2 and the upper detection block 3 match those of a standard bearing 5. In this utility model embodiment, the bottom surface of the upper detection block 3 is a concave arc surface, and the top surface of the lower detection block 2 is a convex arc surface that matches the concave arc surface. When the lower detection block 2 and the upper detection block 3 respectively clamp the bearing 5 to be detected and the standard bearing 5, the measuring tool 4 is used to measure the difference in distance between the lower detection block 2 and the upper detection block 3.

[0046] The working method of this utility model embodiment is as follows: First, the standard bearing 5 is clamped by the lower detection block 2 and the upper detection block 3. The first distance between the lower detection block 2 and the upper detection block 3 is measured. After measurement, the standard bearing 5 is removed, and the bearing 5 to be tested is clamped. The second distance between the lower detection block 2 and the upper detection block 3 is measured. The deformation of the bearing 5 to be tested compared with the standard bearing 5 is reflected in the difference between the second distance and the first distance. The difference between the first distance and the second distance is calculated to obtain the deformation of the bearing 5 to be tested.

[0047] The bearing deformation detection device in this embodiment includes a base, a lower detection block, an upper detection block, and a measuring tool. First, a standard bearing is clamped between the lower and upper detection blocks, and the first distance between the lower and upper detection blocks is measured. After measurement, the standard bearing is removed, and the bearing to be tested is clamped. The second distance between the lower and upper detection blocks is measured. The difference between the first and second distances is calculated, which yields the bearing deformation to be tested. This improves detection efficiency and enables rapid measurement of bearing deformation.

[0048] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the device also includes a mounting rod 6, a slide rail 7, and a drive assembly 8. The mounting rod 6 is mounted on the base 1. The slide rail 7 is vertically mounted on the mounting rod 6 near the lower detection block 2. The drive assembly 8 includes a slider 81 and a clamp 82. The slider 81 is mounted on the upper detection block 3 and is slidably connected to the slide rail 7. The clamp 82 is mounted on the mounting rod 6 and is connected to the slider 81. In this embodiment, lifting the clamp 82 causes the slider 81 to slide downwards along the slide rail 7, and lowering the clamp 82 causes the slider 81 to slide upwards along the slide rail 7. The upper detection block 3 moves in tandem with the slider 7. The mounting rod, slide rail, and drive assembly of this embodiment ensure stable vertical sliding of the upper detection block relative to the lower detection block, thus ensuring the reliability and stability of the detection device.

[0049] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the base 1 has a base plate 11 and four support legs 12. The four support legs 12 are respectively arranged around the bottom surface of the base plate 11. In this embodiment of the utility model, each support leg 12 has an anti-slip structure at the bottom to further ensure stability during the testing process.

[0050] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the base 1 is also provided with two handles 13, which are disposed opposite to each other on the base plate 11 and located on both sides of the lower detection block 2. In this embodiment of the present invention, the two handles 13 disposed opposite to each other on both sides of the base 1 facilitate the movement of the detection device and improve the ease of operation.

[0051] As an optional implementation, in one embodiment of the utility model, the lower detection block 2 is detachably connected to the base 1. In this embodiment of the utility model, the shapes of the lower detection block 2 and the upper detection block 3 need to match the standard bearing 5. The detachable connection makes it easy to replace different lower detection blocks 2 to adapt to the needs of different scenarios, thus increasing the applicable scenarios of the detection device.

[0052] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 2 As shown, the lower detection block 2 has a bearing positioning pin 21 at the center of its top surface. The bearing positioning pin 21 is adapted to the positioning through hole 51 of the bearing 5. In this utility model, the positioning through hole 51 of the bearing 5 is sleeved on the bearing positioning pin 21 to reduce the measurement deviation caused by the inconsistent and unstable placement of the bearing 5 during detection, and further improve the accuracy of the measurement.

[0053] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 2 As shown, two bearing positioning blocks 22 are spaced apart on one side of the top surface of the lower detection block 2. In this embodiment of the invention, two bearing positioning blocks 22 are provided on the side of the top surface of the lower detection block 2 near the slide rail 7, which, together with the bearing positioning pin 21, further improve the consistency of the bearing 5 placement position.

[0054] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the measuring instrument 4 is a dial indicator, which is fixed on the upper measuring block 3, with its probe facing the lower measuring block 2. In this embodiment, a standard bearing 5 is first held between the lower measuring block 2 and the upper measuring block 3, and the dial indicator is zeroed. Then, the standard bearing 5 is removed, and the bearing 5 to be measured is held. The distance between the lower measuring block 2 and the upper measuring block 3 is determined using the dial indicator. The dial indicator measurement is simple and accurate, ensuring the accuracy of the test.

[0055] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, a measuring tool fixing member 9 is also provided. The measuring tool fixing member 9 is disposed on the upper detection block 3. Two protrusions 91 are spaced apart and opposite to each other on one side of the measuring tool fixing member 9. The two protrusions 91 clamp the measuring tool 4. In this embodiment of the present invention, the measuring tool 4, i.e., the probe of the dial indicator, is locked in the two protrusions 91 to fix the dial indicator. This measuring tool fixing member is easy to disassemble and improves the convenience of use.

[0056] This utility model embodiment also provides a bearing deformation detection system, which includes the aforementioned detection device. The detection device includes a base 1, a lower detection block 2, an upper detection block 3, and a detection measuring tool 4. The lower detection block 2 is disposed on the base 1, and the upper detection block 3 is spaced apart and slidably disposed above the lower detection block 2. The detection measuring tool 4 is fixed on the upper detection block 3. The shapes of the lower detection block 2 and the upper detection block 3 match those of a standard bearing 5. When the lower detection block 2 and the upper detection block 3 respectively clamp the bearing 5 to be detected and the standard bearing 5, the difference in distance between the lower detection block 2 and the upper detection block 3 is measured using the detection measuring tool 4. In this embodiment of the utility model, a standard bearing 5 is first clamped between a lower detection block 2 and an upper detection block 3. The first distance between the lower detection block 2 and the upper detection block 3 is measured. After measurement, the standard bearing 5 is removed, and the bearing 5 to be tested is clamped. The second distance between the lower detection block 2 and the upper detection block 3 is measured. The difference between the first distance and the second distance is calculated, which yields the deformation of the bearing 5 to be tested. This improves the testing efficiency and enables rapid measurement of the bearing deformation.
