A shaft vibration monitoring device for motor testing comprises: a base 1;

[0028] A chute 11 is provided on the top of the base 1 , one end of the inner side of the chute 11 is rotatably connected to a screw rod 12 , one end of the screw rod 12 is fixedly mounted with a crank 13 , and the crank 13 is provided at one end of the base 1 ;

[0029] The slider 2 is threadedly connected to the outer side of the screw rod 12. A movable plate 21 is fixedly installed on the top of the slider 2. A fixed frame 22 is fixedly installed on the top of the movable plate 21. A threaded rod 23 is internally threaded on the top of the fixed frame 22. A handle 24 is fixedly installed on the top of the threaded rod 23. The bottom of the threaded rod 23 is rotatably connected to an arc frame 25.

[0030] The bottom plate 4 is arranged at the other end of the base 1. A fixing ring 41 is fixedly installed on the top of the bottom plate 4. A through hole 43 is opened on the top of the fixing ring 41. A mounting ring 44 is fixedly installed on the top of the fixing ring 41. The outer side surface of the mounting ring 44 is rotatably connected to a rotating ring 46. The inner side surface of the rotating ring 46 is fixedly installed with a threaded sleeve 47. The inner side surface of the threaded sleeve 47 is threadedly connected with a screw 48. An elastic piece 49 is fixedly installed on the bottom of the screw 48. A vibration sensor 40 is fixedly installed on one end of the top of the elastic piece 49.

[0031] A controller 42 is fixedly mounted on the front of the fixing ring 41 , and limit blocks 45 are fixedly mounted on both sides of the inner side of the mounting ring 44 . The limit blocks 45 are slidably connected to the inner side of the screw rod 48 .

[0032] The screw 48 is disposed on the inner side of the through hole 43 , and the elastic piece 49 is disposed on the inner side of the fixing ring 41 .

[0033] Limiting frames 31 are fixedly mounted on both sides of the base 1 and both sides of the bottom plate 4 , and connecting rods 3 are provided on the inner side surfaces of the limiting frames 31 .

[0034] A rubber pad 26 is fixedly mounted on the inner side of the arc frame 25 .

[0035] The two sides of the slider 2 are fitted with the two sides of the inner side of the slide groove 11, so that the slider 2 can be limited when in use, and the slider 2 is prevented from rotating when the slider 2 moves, thereby increasing the stability of the slider 2 when moving;

[0036] The rubber pad 26 is provided between the arc frame 25 and the motor, so that the motor can be protected during use.

[0037] The inner side of the limit frame 31 is larger than the connecting rod 3, so that the base 1 and the bottom plate 4 are movably connected. This can prevent the motor from vibrating when it rotates, causing the bottom plate 4 to vibrate together and affecting the monitoring effect of the vibration sensor 40.

[0038] Limiting grooves are provided on both sides of the screw 48, and the limiting blocks 45 slide on the inner sides of the limiting grooves. In this way, when in use, the screw 48 can be limited to prevent the screw 48 from rotating and allow the screw 48 to move vertically up and down;

[0039] The elastic sheet 49 has a certain elasticity. When the shaft of the motor vibrates, it will drive the elastic sheet 49 to vibrate.

[0040] The vibration sensor 40 is connected to the controller 42 , so that after the vibration sensor 40 senses vibration, the vibration information can be displayed on the controller 42 , making it convenient for the user to observe.

[0041] The working principle of the motor shaft vibration monitoring device provided by the utility model is as follows:

[0042] When testing the motor, the user places the motor on the top of the movable plate 21, and then rotates the handle 24, so that the handle 24 drives the threaded rod 23 to be threadedly connected inside the top of the fixed frame 22, so that the bottom of the threaded rod 23 drives the arc frame 25 to move downward, so that the arc frame 25 drives the rubber pad 26 to move downward, so that the rubber pad 26 is pressed on the top of the motor, and then the user rotates the crank 13, so that the crank 13 drives the screw rod 12 to be threadedly connected inside the slider 2, and then the slider 2 drives the movable plate 21 and the motor to move to one side of the fixed ring 41. The user rotates the rotating ring 46 so that the rotating ring 46 drives the threaded sleeve 47 to be threadedly connected to the outer side of the screw 48, so that the bottom of the screw 48 drives the elastic sheet 49 to move downward until the bottom of the elastic sheet 49 is pressed on the output end of the motor. The user then starts the motor and drives the output end to rotate at the bottom of the elastic sheet 49 through the motor. When vibration occurs, the vibration sensor 40 senses the vibration and transmits the signal to the controller 42. At this time, the user can observe through the controller 42.

[0043] Compared with related technologies, the motor shaft vibration monitoring device provided by the present invention has the following beneficial effects:

[0044] Through the mutual cooperation of structures such as the base 1, the slide groove 11, the screw rod 12, the crank handle 13, the slider 2, the movable plate 21, the fixed frame 22, the threaded rod 23, the rotating handle 24 and the arc frame 25, when in use, the user only needs to place the motor on the top of the movable plate 21, and then rotate the rotating handle 24 to drive the threaded rod 23 to be threadedly connected inside the top of the fixed frame 22, and then drive the arc frame 25 to move downward and press on the top of the motor to limit and fix the motor. This makes it convenient for the user to limit and fix the motor, thereby increasing work efficiency.
