Background Art

[0002] Prior art: In the existing cutting fluid control scheme, the cutting fluid nozzle angle is usually adjusted manually to ensure that the nozzle is aligned with the appropriate position in the vertical direction of the tool. After the tool is automatically replaced during the processing, the cutting fluid injection position usually remains unchanged.

[0003] Function: Adjust the cutting fluid nozzle angle so that the nozzle is aimed at the tool tip processing point to ensure that the necessary cooling and lubrication are provided during the tool processing process.

When the tool length changes, the tool tip processing point changes, resulting in inaccurate nozzle position for cutting fluid. If the machine is stopped to adjust the nozzle angle, the operation complexity and time consumption will increase. 3. If the cutting fluid nozzle angle is not adjusted with the tool length change, the cooling and lubrication effects may be unstable, thus affecting the processing quality. 4.

[0048] The device for realizing automatic follow-up flushing device control based on tool length change of the present invention, wherein the device comprises:

[0049] a processor configured to execute computer executable instructions;

[0050] The memory stores one or more computer executable instructions. When the computer executable instructions are executed by the processor, the steps of the method for automatically following the flushing device control based on tool length transformation are implemented.

[0051] The processor of the present invention is used to realize automatic follow-up flushing device control based on tool length transformation, wherein the processor is configured to execute computer executable instructions. When the computer executable instructions are executed by the processor, the various steps of the above-mentioned method for realizing automatic follow-up flushing device control based on tool length transformation are realized.

[0052] The computer-readable storage medium of the present invention stores a computer program thereon, and the computer program can be executed by a processor to implement the various steps of the method for automatically following the control of a flushing device based on tool length transformation.

[0053] In a specific embodiment of the present invention, an automated cutting fluid control method is provided to solve the problems of the prior art, such as the inconvenience of manually adjusting the position of the cutting fluid nozzle, inefficient resource utilization, and unstable cooling and lubrication effects. By realizing the function of automatically adjusting the position of the cutting fluid nozzle when the tool length changes, the present invention aims to improve the injection accuracy and effective utilization rate of the cutting fluid, ensure the cooling and lubrication effects during the cutting process, and thus improve the processing quality and efficiency. At the same time, the automatic adjustment of the nozzle angle can achieve workbench flushing, expanding the application range of the device.

[0054] The invention provides a control method for an automatic cutting fluid control device based on tool length transformation.

[0055] The control device consists of two parts: a control unit and an actuator. The control unit is integrated into the CNC system software; the actuator includes a small binary bit control motor and an adjustable cutting fluid nozzle. The adjustable cutting fluid nozzle is combined with the motor and fixed on the Z axis.

[0056] The control unit is in automatic mode:

[0057] By real-time monitoring of the tool Z-direction offset and the change of the tool tip relative to the machining plane, the tool length change is identified. According to the preset corresponding relationship between the tool length and the cutting fluid nozzle angle, the actuator is automatically controlled to adjust the cutting fluid nozzle angle so that it is always aligned with the contact position between the tool and the machining plane. For specific control flow, see Figure 1 The automatic follow flushing function controls the process.

[0058] Through this automated control method, accurate adjustment of the cutting fluid injection position is achieved, manual operation is avoided, and the injection accuracy and utilization rate of the cutting fluid are improved, thereby ensuring the cooling and lubrication effects of the cutting process.

[0059] The control unit is in manual mode:

[0060] With the ability to control the cutting fluid nozzle angle step adjustment, the operator can flexibly adjust the cutting fluid nozzle angle and spray position. When using the workbench flushing function, the control unit can automatically control the cutting fluid nozzle to swing left and right to flush the workbench and ensure that the workbench remains clean. For specific control procedures, see Figure 2 Manual mode step adjustment and workbench flushing control flow chart.

[0061] An automatic follow-up flushing function module is integrated into the existing CNC software, and the function module realizes automatic adjustment of the cutting fluid nozzle, manual step adjustment and workbench flushing functions during the processing.

[0062] 1. Added the automatic follow-up flushing function operation interface, which is used to preset the automatic follow-up flushing function data and perform operations related to the function.

[0063] The preset data includes:

[0064] 1) The correspondence between tool length, nozzle angle and port control status. From this correspondence, you can query the nozzle angle corresponding to different tool lengths and the port status that needs to be controlled when the nozzle is adjusted to this angle.

[0065] 2) The minimum and maximum angles of the left and right swing of the nozzle when flushing the workbench, as well as the interval time between the left and right swings of the nozzle.

[0066] The available operations include:

[0067] 1) Automatic and manual mode switching.

[0068] 2) Step adjustment of the cutting fluid nozzle angle in positive and negative directions.

[0069] 3) Workbench flushing function.

[0070] 2. Automatic follow-up flushing function realization: In automatic mode, during the machining process, when cutting is turned on, the tool length change is identified by real-time monitoring of the tool Z offset and the change of the tool tip relative to the machining plane. Then, according to the pre-set tool length, nozzle angle and port control state correspondence, the nozzle angle corresponding to the tool length at this time and the output port state that needs to be controlled when adjusting to the nozzle angle are queried, and then the output of the output port is controlled.

[0071] The output port is connected to the binary bit control motor on the actuator, and the control motor automatically adjusts the angle of the cutting fluid nozzle so that it is always aligned with the contact position between the tool and the processing plane.

[0072] 3. Implementation of the cutting fluid nozzle angle step adjustment function: In manual mode, when executing the nozzle angle positive or negative function, the output port output is controlled in a step-by-step manner, and the output port controls the motor rotation to achieve step adjustment of the nozzle angle.

[0073] Workbench flushing function is realized: In manual mode, when the workbench function is turned on, the nozzle angle is controlled to swing left and right between the preset minimum and maximum angles of the workbench flushing to achieve flushing of the workbench.
