Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to an online monitoring device for the life of a tool head of a numerical control machine tool. Background Art

[0002] CNC machine tools are the product of modern high-tech development. Whenever a batch of parts begins to be processed, a large number of inspections need to be completed, including the clamping and alignment of fixtures and parts, the determination of the programming origin of parts, the inspection of the first part, the inspection between processes and the inspection after processing. The main means to complete these inspections are manual inspection, offline inspection and online inspection.

[0003] A Chinese patent discloses an online monitoring device for the life of a CNC machine tool cutter head and a CNC machine tool (authorization announcement number CN208796095U). The patented technology uses a wireless vibration sensor unit to wirelessly transmit data, effectively solving the problem that the wired data transmission method cannot be applied to the application scenario of the cutter head that needs to rotate. The application flexibility is better. At the same time, the wireless vibration sensor unit is placed inside the metal tool handle, which greatly reduces the impact on dynamic balance compared to placing it on the surface of the metal tool handle. In addition, combined with the exposed sheet antenna, it effectively avoids the shielding of the wireless signal by the metal tool handle, ensuring the reliability of data transmission. The sheet antenna is also easier to install and reduces the impact on dynamic balance.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: in actual use, the existing monitoring devices are inconvenient for the staff to adjust the monitoring angle of the installed monitoring devices, resulting in blind spots in the monitoring devices, which affects the device's life monitoring of the machine tool cutter heads and easily causes damage and splashing of the cutter heads, creating safety hazards.

[0027] Reference Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment: nut blocks 15 are fixedly connected to both sides of the rear end of the mounting plate 1, the internal threads of the nut block 15 are connected to a threaded rod 16, the bottom of the threaded rod 16 is fixedly connected to a knob 17, the surface of the threaded rod 16 is slidably connected to a first clamping plate 18, and the front end of the mounting plate 1 is fixedly connected to both sides of the second clamping plate 19, and the staff rotates the knob 17 to drive the threaded rod 16 to rotate, and the threaded connection between the threaded rod 16 and the nut block 15 causes the threaded rod 16 to move upward, driving the knob 17 to push the first clamping plate 18 to move upward, so that the first clamping plate 18 and the second clamping plate 19 clamp the machine tool, thereby fixing the position of the mounting plate 1, realizing the rapid installation of the online monitoring device body 5, and facilitating the staff to disassemble the online monitoring device body 5 for repair or replacement.

When the knob 17 pushes the first clamping plate 18 to move upward, the circular groove 20 and the limit rod 21 The sliding connection limits the moving trajectory of the first clamping plate 18 and prevents the first clamping plate 18 from rotating, which is convenient for the staff to use the first clamping plate 18 and the second clamping plate 19 to clamp the machine tool. When the knob 17 pushes the first clamping plate 18 upward to drive the limit rod 21 to move upward, the flat round block 22 pulls the second spring 23 to extend to accumulate force. When the staff releases the position restriction of the first clamping plate 18 by the knob 17, the force released by the second spring 23 rebounds and pulls the flat round block 22 downward to push the limit rod 21 to drive the first clamping plate 18 to move downward, thereby resetting the position of the first clamping plate 18, which is convenient for the staff to release the clamping of the second clamping plate 19 and the first clamping plate 18 on the machine tool.
