[0014] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0015] In the following description, for the sake of clarity and conciseness, not all of the multiple components shown in the figures are described. The figures illustrate multiple components that provide a fully achievable disclosure of this invention for those skilled in the art. The operation of many of these components will be familiar and obvious to those skilled in the art. Example

[0016] like Figures 1-6 As shown, this embodiment provides a vertical bearing testing machine, including a base 101, a power module 102, a power spindle assembly 103, a bearing testing assembly 104, a vibration loading module 105, and a radial loading module 106. The bearing testing assembly 104 includes a support base 107 and a spindle 108. The top of the support base 107 is provided with a detection mechanism for detecting the sway of the spindle 108. The testing mechanism includes multiple support blocks 701 fixedly connected to the top of the support base 107, and each support block 701 has a moving plate 702 connected to its side wall via a first telescopic mechanism. The side wall of the moving plate 702 is provided with ball bearings 703, which can roll on the side wall of the spindle 108. The top of the support base 107 is provided with a testing component for detecting the movement of the moving plate 702. During the test, it is convenient to detect the shaking of the spindle 108 in real time so as to carry out timely maintenance and replacement and ensure the accuracy of the test.

[0017] The first telescopic mechanism includes a connecting block 201 fixedly connected to the side wall of the support block 701, and two moving rods 202 are inserted into the side wall of the connecting block 201. One end of the moving rod 202 is fixed to the side wall of the moving plate 702, and the other end of the moving rod 202 is fixedly connected to a stop block 203. A first spring 204 is sleeved on the side wall of each moving rod 202, which guides and resets the movement of the moving plate 702.

[0018] The detection assembly includes an L-shaped plate 301 fixedly connected to the top of the support 107, and a V-shaped plate 302 connected to the top of the L-shaped plate 301 via a second telescopic mechanism. A push plate 304 is fixedly connected to the side wall of the V-shaped plate 302, and a connecting plate 305 is fixedly connected to the side wall of one of the L-shaped plates 301. A distance sensor 306 is fixedly inserted into the top of the connecting plate 305, and an annular plate 303 is connected to the bottom of the connecting plate 305 via a third telescopic mechanism. A push mechanism for pushing the V-shaped plate 302 upward is provided on the side wall of the stop block 203. When the main shaft 108 shakes, the ball bearings 70... 3. The moving plate 702 is pushed to move closer to the connecting block 201. When the moving plate 702 moves, it can push the V-shaped plate 302 upward through the pushing mechanism. When the V-shaped plate 302 moves upward, it can drive the pushing plate 304 to move upward synchronously and push the annular plate 303 upward. When the V-shaped plate 302 moves upward, it can drive the pushing plate 304 to move upward synchronously and push the annular plate 303 upward. This movement is detected by the distance sensor 306, which facilitates real-time detection of the shaking of the spindle 108 so that timely maintenance and replacement can be carried out to ensure the accuracy of the test.

[0019] The pushing mechanism includes a fixed block 401 fixedly connected to the side wall of the support block 701, and a rotating plate 403 rotatably connected to the side wall of the fixed block 401 via a rotating shaft 402. The upper end of the rotating plate 403 is inserted into the V-shaped plate 302, and a sliding groove 404 is formed on the side wall of the rotating plate 403. A mounting block 405 is fixedly connected to the side wall of the stop block 203, and a pushing pin 406 is fixedly connected to the side wall of the mounting block 405. The pushing pin 406 is inserted into the sliding groove 404. When the main shaft 108 shakes... When the amplitude is large, the ball bearing 703 pushes the moving plate 702 to move closer to the connecting block 201, the first spring 204 is compressed, and the moving rod 202 can drive the stop block 203 to move, and then the mounting block 405 drives the push pin 406 to slide in the slide groove 404, which can push the rotating plate 403 to rotate along the rotating shaft 402. When the upper end of the rotating plate 403 slides along the side wall of the V-shaped plate 302, it can push the V-shaped plate 302 to move upward.

[0020] The second telescopic mechanism includes two first sleeve rods 501 fixedly connected to the top of the V-shaped plate 302, and a first sleeve 502 is sleeved on the side wall of each first sleeve rod 501. The upper end of the first sleeve 502 is fixed to the top of the L-shaped plate 301, and a second spring 503 is sleeved on the side wall of each first sleeve 502, which guides and resets the movement of the V-shaped plate 302.

[0021] The third telescopic mechanism includes two second sleeves 602 fixedly connected to the bottom of the connecting plate 305, and a second sleeve rod 601 is inserted into each second sleeve 602. The lower end of the second sleeve rod 601 is fixed to the top of the annular plate 303, and a third spring 603 is sleeved on the side wall of each second sleeve 602, which guides and resets the movement of the V-shaped plate 302.

[0022] Working principle: During the test, the bearing to be tested is installed in the bearing test assembly 104. The power module 102 is started and rotated under the drive of the power module 102. The power spindle assembly 103, as the core support and power transmission component of the bearing test assembly, drives the bearing and other components in the bearing test assembly to move in a set manner through the spindle 108, simulating the working rotation of the bearing. The vibration loading module 105 is used to apply vibration load to the bearing test assembly to simulate the vibration and impact that the bearing may be subjected to in actual operation, so as to test the performance of the bearing under vibration conditions, such as vibration resistance and the impact of vibration on bearing operation. The radial loading module 106 mainly applies radial load to the bearing test assembly to simulate the radial force that the bearing bears in actual operation, such as the radial pressure that the bearing is subjected to when mechanical equipment is running, so as to test the bearing capacity, wear condition and other performance of the bearing under radial load.

[0023] During the test, under the action of the first spring 204, the ball 703 abuts against the side wall of the main shaft 108. When the main shaft 108 rotates, it can drive the ball 703 to roll. At the same time, under the action of the first spring 204, the ball 703 can play a certain limiting effect on the main shaft 108 and reduce its shaking.

[0024] Furthermore, when the spindle 108 vibrates significantly, the ball bearing 703 pushes the moving plate 702 towards the connecting block 201, compressing the first spring 204. The moving rod 202 then moves the stop block 203, which in turn drives the push pin 406 to slide within the groove 404 via the mounting block 405. This causes the rotating plate 403 to rotate along the shaft 402. When the upper end of the rotating plate 403 slides along the side wall of the V-shaped plate 302, it pushes the V-shaped plate 302 upwards. Simultaneously, the second spring 503 is compressed. As the V-shaped plate 302 moves upwards, it drives the push plate 304 to move upwards synchronously, pushing the annular plate 303 upwards. The third spring 603 is compressed. At this point, the distance sensor 306 can detect the vibration of the spindle 108 in real time, facilitating timely maintenance and replacement to ensure the accuracy of the test.

[0025] 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 modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
