Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figures 1-5, the present utility model provides a technical solution: a vibration monitoring system for a numerically controlled machine tool, including a protective shell 1. A vibration monitoring device main body 1 is fixedly installed at the center of one side of the protective shell 1. Fixing plates 4 are fixedly connected to both the top and bottom of the protective shell 1. A clamping plate 5 is arranged on one side of the fixing plate 4. A fixing bolt 1 6 is threadedly connected to a position near the center on the other side of the fixing plate 4. The clamping plate 5 is threadedly connected to a threaded rod 7. A pressing plate 8 is arranged at the bottom of the threaded rod 7. A vibration monitoring device main body 2 3 is fixedly installed at the rear end of the pressing plate 8. An auxiliary limiting plate 11 is fixedly connected to one side of the pressing plate 8. A fixing bolt 2 13 is threadedly connected to a position near one side of the auxiliary limiting plate 11. Both the vibration monitoring device main body 1 2 and the vibration monitoring device main body 2 3 include a sensor, a signal conditioning circuit, a data acquisition and processing module, a power supply and power management, a communication interface and data transmission, and a human-machine interface.

[0016] The detection direction of the vibration monitoring device main body 1 2 is the Y-axis, and the detection direction of the vibration monitoring device main body 2 3 is the X-axis.

[0017] A clamping groove 14 is opened at the center of one side of the fixing plate 4. One side of the clamping plate 5 penetrates into the inside of the clamping groove 14 and is clamped with the clamping groove 14, which can play a role in fixing and limiting.

[0018] One side of the fixing bolt 1 6 penetrates into the inside of the clamping plate 5 and is threadedly connected to the clamping plate 5, which can fix the clamping plate 5.

[0019] The top of the pressing plate 8 is rotationally connected to the bottom of the threaded rod 7 through a bearing, which can facilitate the movement of the pressing plate 8.

[0020] Moving grooves 9 are opened at both the top and bottom of the other side of the protective shell 1. A moving plate 10 is slidably connected to a position near the bottom of the pressing plate 8. One side of the moving plate 10 penetrates into the inside of the moving groove 9 and is slidably connected to the moving groove 9, which can play a role in limiting the movement of the pressing plate 8.

[0021] The other side of the moving plate 10 is fixedly connected to a movable plate 12. The bottom of the movable plate 12 is slidably connected to the top of the auxiliary limiting plate 11, which can play a role in supporting the movement of the moving plate 10.

[0022] Working principle: When it is necessary to clamp and fix the main body II 3 of the vibration monitoring device to the numerically controlled machine tool, the user places the protective shell 1 on one side of the numerically controlled machine tool, and then rotates the threaded rod 7 to drive the pressing plate 8 to move inward, so that the two pressing plates 8 move relatively and closely adhere to the surface of the numerically controlled machine tool. Then, rotate the fixing bolt II 13 so that the fixing bolt II 13 is threadedly connected to the surface of the numerically controlled machine tool to complete the installation; when it is not necessary to fix the main body II 3 of the vibration monitoring device, the user first rotates the fixing bolt I 6 to rotate the fixing bolt I 6 out of the inside of the clamping plate 5, and then moves the clamping plate 5 outward so that the clamping plate 5 disengages from the clamping groove 14 in the fixing plate 4 and the moving plate 10 disengages from the moving groove 9. Remove the clamping plate 5 from the protective shell 1, then place the protective shell 1 on one side of the numerically controlled machine tool, rotate the fixing bolt I 6, and threadedly connect the fixing bolt I 6 to one side of the numerically controlled machine tool to complete the installation, and perform detection through the main body I 2 of the vibration monitoring device.

[0023] To sum up: For this numerically controlled machine tool vibration monitoring system, through the design of the protective shell 1, the fixing plate 4, the clamping plate 5, the fixing bolt I 6, the threaded rod 7, the pressing plate 8, the auxiliary limiting plate 11, the movable plate 12 and the fixing bolt II 13, it can facilitate the user to fix the vibration monitoring device to the numerically controlled machine tool in a clamping or threaded connection manner, improving the convenience of installation. This design, first, can facilitate the user to threadedly connect the vibration monitoring device to the numerically controlled machine tool through the fixing bolt I 6; second, the user can fix the clamping plate 5 to the inside of the fixing plate 4, so that one end of the moving plate 10 is slidably connected to the moving groove 9. Then, when the threaded rod 7 rotates, the pressing plate 8 is moved to the surface of the numerically controlled machine tool, and the monitoring device is clamped to the numerically controlled machine tool through the two pressing plates 8. Finally, it is fixed through the fixing bolt II 13 to complete the installation. The operation is simple and convenient to use, improving the practicability of the vibration monitoring device and meeting the usage requirements of existing users.
