Abstract
Description
Technical Field

[0002] In the field of machining, especially in the processing of large machine tools such as boring and milling machines and gantry milling machines, workpiece fixation and machining accuracy have always been key factors affecting production efficiency and product quality. Normally, the workpiece is firmly fixed to the machine tool's worktable, and the machine tool's cutting tools then perform a series of precision machining operations such as boring, milling, and drilling. However, in actual machining processes, due to the combined effects of various factors, the workpiece may unexpectedly move or shift, leading to a decrease in machining accuracy. One commonly used monitoring method is to use a dial indicator to detect workpiece displacement. However, dial indicators require periodically stopping the machine tool during machining to manually measure the workpiece displacement. This measurement process has a significant lag, making it impossible to detect displacement in a timely manner, resulting in workpiece scrap and additional economic losses. Utility Model Content

Figure 1 As shown, the displacement monitoring device includes a control device 100, a first alarm device 200, a displacement detection device 300, a power supply battery 400, and a second alarm device 500. The control device 100 includes a control box 110 and a controller 120. The control box 110 serves as the mounting enclosure for the displacement monitoring device, protecting the electrical components installed inside from external environmental interference. Simultaneously, the control box 110 enhances the portability of the displacement monitoring device, facilitating its movement between multiple machine tools. The controller 120 is installed inside the control box 110. The controller 120 receives the electrical signal output from the displacement detection device 300 and determines the displacement value of the machined workpiece 20. The controller 120 stores an alarm value representing the maximum allowable offset of the machined workpiece 20. The first alarm device 200 is integrally fixedly mounted on the control box 110, further enhancing the portability of the displacement monitoring device. The first alarm device 200 is electrically connected to the controller 120.

It should be noted that the first alarm device 200 can be any suitable type of structure that can achieve sound or visual warning, and can be obtained through general commercial means. For example, the first alarm device 200 can be a buzzer or a warning light, but is not limited thereto.

The displacement detection device 300 is fixedly installed on the machine tool 10, worktable, or ground beside the machined workpiece 20, but is not limited to these locations. The measuring probe of the displacement detection device 300 abuts against the machined workpiece 20, and the displacement detection device 300 is electrically connected to the controller 120. The displacement detection device 300 is used to measure the displacement deviation of the machined workpiece 20 and outputs the corresponding electrical signal to the controller 120. This overcomes the lag of traditional measurement methods, ensuring that any minute displacement changes during processing can be captured in a timely manner. The displacement detection device 300 can be a commonly used displacement detection sensor type such as a laser displacement sensor, a grating displacement sensor, or a capacitive displacement sensor, and can be obtained through general commercial means.
[0027] Please see Figure 1 and Figure 3The power supply battery 400 is electrically connected to the controller 120 and is fixedly installed inside the control box 110. The power supply device 400 uses a storage battery to independently power the controller 120, the first alarm device 200, and the displacement detection device 300, thereby improving the portability of the displacement monitoring device and allowing it to be moved to any machine tool where needed.

The second alarm device 500 is located beside the control panel 11 of the machine tool 10, and the first alarm device 200 is located beside the machined part 20 of the machine tool 10. This dual alarm mechanism not only improves the reliability of the alarm but also ensures that operators can detect abnormalities immediately, thereby taking timely measures to avoid machining errors or workpiece scrap caused by the offset of the machined part 20, and effectively prevents safety accidents caused by the failure to detect alarm signals in time. It should be noted that the second alarm device 500 can be any suitable type of structure that can achieve sound or visual warning, and can be obtained through general commercial means. For example, the second alarm device 500 can be a buzzer or a warning light, but is not limited thereto.

Through the cooperation of the signal transmitter 130 and the signal receiver 510, wireless communication between the control device 100 and the second alarm device 500 is realized. Without the limitation of wired connection, it can be conveniently installed beside the control panel 11 of the machine tool 10 for alarm purposes, improving the timeliness of alarm response in large machine tools or complex working environments.

Specifically, the first preset direction and the second preset direction are any coordinate directions pointing to the surface of the machined workpiece 20 to be tested, that is, any coordinate direction of the displacement change of the machined workpiece 20 to be tested can be detected in a timely manner. For example, the first preset direction is the X-axis and the second preset direction is the Y-axis, but it is not limited thereto.
[0031] In one embodiment of this utility model, the first displacement detection sensor 310 and the second displacement detection sensor 320 adopt LVDT displacement sensors, namely linear variable differential transformer displacement sensors, which can achieve high-precision displacement monitoring.

This ensures the stability of the working state while meeting the requirements for portability.
[0035] In one embodiment of this utility model, both the first alarm device 200 and the alarm 520 employ audible and visual warning lights. The audible and visual warning lights provide both sound and light alarms. In noisy industrial environments, sound alarms can quickly attract the attention of operators. Light alarms further enhance the visibility of the alarm through high-brightness flashing lights, ensuring timely detection even at greater distances or in poor visibility conditions. It should be noted that audible and visual warning lights have wide applications in various industries and can be obtained through general commercial means.
