Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example 1
[0025] A military bearing tester with shock absorption function, such as Figure 1-Figure 3 As shown, it includes a base 1, a slide rail is provided on the top of the base 1, a control console 11 is fixedly installed on the top of the right end of the control console 11, a pressure sensor 12 is fixedly installed on the top of the left end of the control console 11, a bearing plate 14 is fixedly installed on the top of the middle end of the control console 11, and a bearing body 15 to be tested is rotatably installed on the inner wall of the bearing plate 14. The motor 13 is turned on, and the motor 13 drives the bearing body 15 to be tested to rotate on the inner wall of the bearing plate 14. The control console 11 is operated and the pressure sensor 12 is turned on. The pressure sensor 12 tests the performance of the bearing body 15 to be tested. However, the motor 13 will generate vibration when it is operating, and the vibration will drive the control console 11 to vibrate on the top of the base 1. The vibration will cause the test data to change, thereby causing data distortion. The outer wall of the control console 11 is provided with a shock absorbing device 2 for shock absorption, and the outer wall of the bearing plate 14 is provided with a lubrication device 3 for lubrication.
[0026] The shock absorbing device 2 includes a mounting slide block 21, a shock absorbing spring 22 and a stop plate 23. The mounting slide block 21 is mounted on the outer wall of the console 11, and the mounting slide block 21 is fixedly connected to the outer wall of the console 11, and the bottom end of the mounting slide block 21 is slidably mounted on the inner wall of the slide rail of the base 1. When the console 11 vibrates, the console 11 will drive the mounting slide block 21 to slide left and right on the inner wall of the slide rail of the base 1, and the shock absorbing spring 22 is mounted on the inner wall of the slide rail of the base 1, and the shock absorbing spring 22 is fixedly connected to the inner wall of the slide rail of the base 1, and the stop plate 23 is mounted on one end of the shock absorbing spring 22 close to the mounting slide block 21, and the stop plate 23 is fixedly connected to one end of the shock absorbing spring 22 close to the mounting slide block 21, and the mounting slide block 21 will contact the stop plate 23 on the inner wall of the slide rail while sliding left and right, and the stop plate 23 will absorb the force generated by the vibration through the shock absorbing spring 22, thereby reducing the impact on the console 11 and ensuring the accuracy of the test data and the stability of the equipment.
[0027] The shock absorbing device 2 also includes a fixing plate 24, an air cylinder 25, an airway tube 26, an air rod 27, a connecting plate 28, a push tube 29 and a buffer plate 210. The fixing plate 24 is fixedly mounted on the top of both ends of the base 1, the air cylinder 25 is fixedly mounted on the side of the fixing plate 24 away from the console 11, the airway tube 26 is fixedly mounted on the outer wall of the air cylinder 25, the airway tube 26 is connected to the air cylinder 25, the air rod 27 is slidably mounted on the inner wall of the airway tube 26, the connecting plate 28 is fixedly mounted on one end of the air rod 27 close to the console 11, and both ends of the connecting plate 28 are fixedly mounted on the side walls of the mounting slider 21. When the mounting slider 21 slides left and right, the mounting slider 21 will drive the connecting plate 28 to slide left and right. 28 drives the gas rod 27 to slide left and right, and the gas rod 27 will compress the gas in the airway tube 26. The resistance cylinder 29 is slidably installed on the inner wall of the air pressure cylinder 25, so that the gas between the air pressure cylinder 25 and the resistance cylinder 29 pushes the resistance cylinder 29 forward to move. The buffer plate 210 is fixedly installed on the end of the resistance cylinder 29 close to the console 11. The end of the buffer plate 210 close to the console 11 is made of rubber. The resistance cylinder 29 drives the buffer plate 210 to move inward. The rubber surface of the buffer plate 210 can buffer the vibration of the console 11. At the same time, the rubber surface can quickly rebound to its original state after being subjected to external force, so as to prevent excessive shaking of the console 11, thereby significantly improving the seismic performance of the entire test system.
[0028] When the utility model is used, a military bearing tester with a shock absorbing function is turned on by turning on the motor 13, which drives the bearing body 15 to be tested to rotate on the inner wall of the bearing plate 14, and operating the control console 11, turning on the pressure sensor 12, and testing the performance of the bearing body 15 to be tested. However, the motor 13 generates vibrations when it is in operation, and the vibrations drive the control console 11 to vibrate on the top of the base 1. The vibrations cause the test data to change, thereby causing data distortion. When the control console 11 vibrates, the control console 11 drives the installation slider 21 to slide left and right on the inner wall of the slide rail of the base 1. When the installation slider 21 slides left and right, it will contact the abutment plate 23 on the inner wall of the slide rail. The abutment plate 23 then absorbs the force generated by the vibration through the shock absorbing spring 22, thereby reducing the impact on the control console 11 and ensuring the accuracy of the test data and the stability of the equipment.
[0029] When the mounting slider 21 slides left and right, the mounting slider 21 will drive the connecting plate 28 to slide left and right, and the connecting plate 28 will drive the gas rod 27 to slide left and right. The gas rod 27 will compress the gas in the airway tube 26, so that the gas between the air pressure cylinder 25 and the resistance cylinder 29 pushes the resistance cylinder 29 forward to move, and the resistance cylinder 29 drives the buffer plate 210 to move inward. The rubber surface of the buffer plate 210 can buffer the vibration of the console 11. At the same time, the rubber surface can quickly rebound to its original state after being acted upon by external force, thereby preventing excessive shaking of the console 11, thereby significantly improving the seismic performance of the entire test system.
