Abstract
Description
Technical Field
[0001] The present application relates to the field of fixture technology, and specifically to a fixture for bearing detection. Background Art
[0002] Bearings are crucial components in mechanical equipment. To ensure the reliability and durability of bearings in various complex environments, regular inspections are particularly important. Bearing radial stiffness testing is a type of bearing inspection. Its purpose is to evaluate the deformation of the bearing when subjected to force, thereby determining its reliability and stability in actual work.
[0003] The fixture can firmly clamp the bearing to ensure that the bearing will not move or fall off due to force during the test. This clamping effect ensures the accuracy and reliability of the test, so that the test results can truly reflect the radial stiffness performance of the bearing.
[0004] For example, the patent with publication number CN204116134U discloses a rolling bearing radial stiffness test fixture. The patent has an arc groove on the base pressure plate. This design ensures that when the short shaft undergoes radial displacement with the inner ring of the bearing, it will not interfere with the base pressure plate, that is, it avoids contact between the short shaft and the base pressure plate, affecting the displacement of the short shaft and indirectly affecting the test accuracy.
[0005] However, in the stiffness test of the bearing, due to the high pressure, the bearing may roll under the action of external force due to insufficient clamping force or incorrect clamping method during the actual test process. At this time, the staff needs to make adjustments, which will extend the test time and reduce the test efficiency.
[0006] Therefore, it is necessary to provide a bearing detection fixture to solve the above problems.
[0007] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0017] Furthermore, the screw rod is provided with two groups of threads with opposite thread directions, and the two groups of threads are respectively connected to the two groups of slider threads.
[0018] Furthermore, a clamping plate is fixedly provided on the upper end of the slider, a connecting rod is rotatably provided on the upper end of the clamping plate, and fixing bolts are threadedly connected at the connection points at both ends of the connecting rod.

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0031] like Figure 1-Figure 2 As shown, the present application provides a fixture for bearing inspection, comprising a base plate 1 and a clamping mechanism 2 fixedly arranged on the upper end of the base plate 1, wherein the clamping mechanism 2 is used to clamp and fix the bearing to be inspected;
[0032] The clamping mechanism 2 includes a slide rail 20 fixedly mounted on the upper end of the base plate 1. Two sets of mounting seats 21 are fixedly mounted at both ends of the slide rail 20. A screw rod 23 is rotatably mounted between the two sets of mounting seats 21. A hand wheel 25 is fixedly mounted at one end of the screw rod 23 to facilitate rotation of the screw rod 23. Two sets of sliders 24 are slidably mounted on the upper end of the slide rail 20, and the sliders 24 are threadedly connected to the screw rod 23.
[0033] It should be noted that the screw 23 is provided with two sets of threads (not shown in the figure) with opposite thread directions, and the two sets of threads are respectively threadedly connected to the two sets of sliders 24. Therefore, when the handwheel 25 is turned to drive the screw 23 to rotate on the mounting seat 21, the two sets of sliders 24 are driven to move closer to or away from each other along the slide rail 20, thereby achieving the purpose of clamping the bearing to be tested.
[0034] At the same time, a clamping plate 26 is fixedly provided on the upper end of the slider 24, and the clamping plate 26 is used to clamp the bottom end of the bearing to be tested, so that the clamping mechanism 2 can smoothly clamp the bearing.
[0035] At the same time, in order to prevent the bearing from falling due to external force during the detection process, a connecting rod 27 is rotatably provided at the upper end of the clamping plate 26, and a pressing block 28 is rotatably provided at the other end of the connecting rod 27 to facilitate the pressing of the bearing to be detected, thereby preventing the bearing from shifting upward or falling due to external force during the clamping process;
[0036] In addition, fixing bolts 29 are threadedly connected at the connection points at both ends of the connecting rod 27. When the bearing needs to be tightened, the pressing block 28 can be pressed on the bearing to be tested by toggling the connecting rod 27. At this time, the fixing bolts 29 at both ends can be rotated to fix the bearing. When unlocking is required, only the fixing bolts 29 need to be rotated in the opposite direction.
[0037] like Figure 2 and Figure 3 As shown, in order to prevent the bearing to be tested from rolling due to external force before the test process, a hollow chamber is fixedly provided inside the pressing block 28, and a stabilizing mechanism 3 is provided on both sides of the hollow chamber inside the pressing block 28. The stabilizing mechanism 3 is used to further fix the bearing to be tested;
[0038] The stabilizing mechanism 3 includes a plurality of telescopic rods 31 fixedly arranged on both sides of the hollow chamber. The telescopic rods 31 include a fixed sleeve fixedly arranged inside the pressing block 28 and a sliding rod slidably arranged inside the fixed sleeve. A stabilizing bar 33 is fixedly arranged at one end of the sliding rod. The stabilizing bar 33 is used to directly contact the bearing to be tested so as to stabilize the bearing to be tested.
[0039] At the same time, a spring 32 is sleeved on the sliding rod, and the spring 32 is used to provide compression, and a fixing block 34 is fixedly provided at the lower end of the stabilizing bar 33, and a barb 36 is fixedly provided on the fixing block 34. At the same time, a positioning ring 35 is fixedly provided on one side of the pressing block 28, and the barb 36 is adapted to the positioning ring 35. Therefore, before the bearing to be tested is stabilized, the sliding rod can be slid along the fixing sleeve by pulling the barb 36, thereby compressing the spring 32 on the outside of the sliding rod until the barb 36 is hung on the positioning ring 35 to stop;
[0040] When the bearing needs to be stabilized, the hook 36 can be opened. At this time, the spring 32 releases the compression, thereby pushing the sliding rod to push the stabilization bar 33 to fit the surface of the bearing to be tested. When the stabilization bars 33 at both ends fit at the same time, the bearing to be tested can be clamped laterally, thereby achieving multi-directional clamping of the bearing, thereby preventing the bearing to be tested from shifting.
[0041] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
