Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a vibration monitoring mechanism for unstable mobile equipment. Background Technology

[0002] Vibration sensors are widely used in unstable mobile devices such as drones, automobiles, and robots to monitor the vibration status of the equipment. In existing technologies, vibration sensor fixtures typically employ a fixed design, securing the sensor to the equipment with bolts or clips. However, such installation fixtures often suffer from the following problems: poor contact quality: the vibration sensor cannot maintain good contact with the measured item on the moving production line, resulting in low-quality data. Secondly, lack of shock absorption: this makes the sensor prone to damage in unstable environments. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a vibration monitoring mechanism for unstable mobile devices, which can enable the vibration sensor to maintain stable pressure against the product to be monitored and to monitor vibration data synchronously.

[0004] This utility model is achieved by the following technical solution:

[0005] A vibration monitoring mechanism for unstable mobile equipment includes a vibration sensor, a pressure sensor, a telescopic sleeve, a universal joint assembly, a linear motor module, and a longitudinal drive device. The linear motor module is provided with a transverse guide rail. A movable base is provided on the transverse guide rail. The longitudinal drive device is fixed on the movable base. The longitudinal drive device is drivenly connected to a mounting base. The outer surface of the mounting base is fixed to a connecting base. A universal joint assembly is provided on the outer surface of the connecting base. A connecting rod is fixed on the outer surface of the universal joint assembly. A telescopic sleeve is fitted onto the connecting rod. A pressure sensor and a vibration sensor are respectively provided on the free end of the connecting rod from the inside to the outside.

[0006] Furthermore, the universal joint assembly includes a connecting pin, a tension spring, and a set of universal joints; the set of universal joints is movably connected by a connecting pin located in the middle, and the two sides of the set of universal joints are connected by tension springs respectively.

[0007] Furthermore, the connecting seat includes a lower connecting seat and an upper connecting seat; the lower connecting seat and the upper connecting seat are fixed by bolts passing through countersunk holes.

[0008] Furthermore, a shock-absorbing spring is provided between the telescopic sleeve and the pressure sensor.

[0009] Furthermore, the connecting upper seat is connected to the universal joint via a bolt connection assembly.

[0010] Furthermore, the longitudinal drive device includes a servo motor, a lead screw, a protective shell, and a threaded sleeve; the servo motor drives the lead screw to engage with the threaded sleeve mounted on the mounting base; the lead screw is protected by a protective shell; a set of guide rods is mounted on the mounting base; the guide rods are connected to guide holes on the side of the movable base.

[0011] In summary, this utility model has the following beneficial effects: The linear motor module drives the moving base to move back and forth on the transverse guide rail, enabling the vibration sensor to synchronously monitor vibrations along with the products on the production line. The longitudinal drive device ensures the vibration sensor is in contact with the surface of the product being monitored, while the pressure sensor ensures stable contact pressure between the vibration sensor and the products on the production line. This allows the vibration sensor to stably collect vibration data from the product surface, making it suitable for unstable mobile devices and dynamic measurement scenarios. It ensures stable contact between the vibration sensor and the measured object, thus achieving high-quality vibration data acquisition. Furthermore, by incorporating a shock-absorbing spring between the telescopic sleeve and the pressure sensor, the impact of equipment movement on the vibration sensor is reduced, improving the sensor's lifespan and the number of tests.
