Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motors, in particular to a monitoring mechanism for motors. Background Art
[0002] A motor is a device that can convert electrical energy into mechanical energy. Its working principle is based on the law of electromagnetic induction. A motor is usually composed of a stator and a rotor. The stator generates a rotating magnetic field, and the rotor rotates in the magnetic field, thereby converting electrical energy into mechanical energy. There are many types of motors, the most common ones are DC motors, AC motors, stepper motors, servo motors, etc. Motors are widely used in industry, transportation, energy, electricity and other fields.
[0003] When using a motor, it usually needs to be used in conjunction with a shaft. The shaft is one of the important components of the motor. It connects the motor's rotor with the mechanical load, transmits torque and rotational motion. Through the shaft, the motor can convert rotational motion into various mechanical actions and drive the operation of various mechanical equipment.
[0004] During the use of the motor, if abnormal vibration occurs, the shaft will be subjected to large torque and vibration. The vibration amplitude of the shaft will be larger than that of the motor, and it is very easy to cause the connection between the shaft and the mechanical equipment to break. At the same time, since it is normal for the motor to generate a small amount of vibration during operation, it increases the difficulty of motor vibration monitoring. To this end, we propose a monitoring mechanism for motors. Utility Model Content
[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0006] A monitoring mechanism for a motor comprises a fixed seat, wherein a vibration cavity is provided on the left side and the lower side of the inner wall of the fixed seat, the inner walls of the two vibration cavities are provided with fixed opening blocks, the inner walls of the two fixed opening blocks are slidably connected with vibration columns, one end of the two vibration columns respectively penetrates one side of the inner wall of the corresponding vibration cavity and extends to the inner wall of the fixed seat, the other end of the two vibration columns is fixedly connected with a metal frame, the inner walls of the two metal frames are provided with metal balls, the two fixed opening blocks are respectively fixedly connected with a spring on one side of the corresponding metal frame, the column walls of the two vibration columns are located on one side of the fixed opening blocks close to the spring and are fixedly connected with a limiting block, the front sides of the inner walls of the two vibration cavities are provided with limiting openings, the inner walls of the two limiting openings are provided with fixed blocks, the rear sides of the two fixed blocks are respectively fixedly connected with the front sides of the corresponding fixed opening blocks, and the front sides of the two fixed blocks are provided with a first bolt. In the process of using the monitoring mechanism, while ensuring the monitoring effect of abnormal vibration of the motor, it is also possible to avoid the influence of harmless vibration generated during the operation of the motor on the monitoring effect, which is helpful for use.
[0007] Furthermore, scale lines are provided on one side of the two limit openings in front of the fixing seat.
[0008] Furthermore, speakers are fixedly connected to one end of the two limit openings in front of the two fixing seats.
[0009] Furthermore, the bottom surface of the fixing seat is fixedly connected to a bottom plate, and mounting holes are provided at four corners of the bottom surface of the bottom plate.
[0010] Furthermore, a placement seat is fixedly connected to the rear side of the top surface of the bottom plate, and the placement seat is a mesh structure.
[0011] Furthermore, a motor is arranged on the inner wall of the placement seat, an output end of the motor is fixedly connected with a shaft rod, and a front end of the shaft rod extends to the front of the fixing seat through the inner wall of the fixing seat.
[0012] Furthermore, two connection blocks are fixedly connected to the left and right sides of the motor, and the plurality of connection blocks are fixed to the placement seat by second bolts.
[0013] The beneficial effects of the utility model are as follows:
[0014] 1. When using this monitoring mechanism, the motor is in the starting state and the shaft is rotating. If the motor only generates a small amount of vibration, there is a certain distance between the vibration column and the shaft, and the slight vibration of the shaft will not contact the vibration column, thereby not triggering the monitoring mechanism to alarm. When the motor generates abnormal vibration, the shaft generates a larger vibration amplitude, thereby squeezing the vibration column. Under the action of the spring, the vibration column is continuously squeezed by the shaft to generate vibration, thereby causing the metal ball to vibrate on the metal frame and generate a loud noise to alarm.
[0015] 2. The scale line makes it easy to observe the adjustment distance of the vibration column, which helps to facilitate the use of the equipment. The speaker amplifies the sound produced by the metal ball, which helps to improve the effect of the alarm. The bottom plate makes the equipment more stable, and the mounting hole facilitates the installation of the equipment on the operating platform, improving the practicality of the equipment.
[0016] 3. The placement seat supports and positions the motor, and the mesh placement seat helps to dissipate the heat of the motor. The connecting block and the second bolt fix the motor on the placement seat to ensure the stability of the motor in normal use. At the same time, the second bolt facilitates the disassembly of the motor, which helps to make the equipment easier to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.
[0024] The device's "front, back, left, right" viewing angles are Figure 1 The directions in the attached drawings are taken as reference.

By moving the position of the fixed opening blocks 3, the distance between the vibration column 4 and the shaft 17 can be adjusted, so that the device is suitable for shafts 17 with different diameters. The inner walls of the two fixed opening blocks 3 are slidably connected with the vibration columns 4, one end of the two vibration columns 4 respectively penetrates through one side of the inner wall of the corresponding vibration cavity 2 and extends to the inner wall of the fixed seat 1, the other ends of the two vibration columns 4 are fixedly connected with metal frames 5, the inner walls of the two metal frames 5 are provided with metal balls 6, the two fixed opening blocks 3 are respectively fixedly connected to one side of the corresponding metal frames 5 with springs 7, the column walls of the two vibration columns 4 are located on the side of the fixed opening blocks 3 close to the spring 7 and are fixedly connected with limiting blocks 8, the front sides of the inner walls of the two vibration cavities 2 are provided with limiting openings 9, and the inner walls of the two limiting openings 9 are provided with fixed blocks. 10. The rear sides of the two fixed blocks 10 are respectively fixedly connected with the front sides of the corresponding fixed opening blocks 3.
