[0002] In related technologies, a circular arc groove on a plate-shaped workpiece is a groove with a circular arc-shaped cross-section on the bottom surface of the plate-shaped workpiece.

[0003] For circular arc grooves on plate-shaped workpieces, they are usually machined using a milling machine. This typically requires the use of special cutting tools, namely milling cutters with a circular arc-shaped cutting edge. The special cutting edge shape of these tools is used to machine the circular arc grooves on the plane of the plate-shaped workpiece.

[0004] However, existing machining methods for processing arc grooves on the plane of plate-shaped workpieces have significant limitations on cutting tools, resulting in high processing costs and difficulties in procuring cutting tools. Summary of the Invention

The support plate is hinged to the base plate and is used to support the plate-shaped workpiece. The clamping mechanism is used to clamp and fix the plate-shaped workpiece. The angle adjustment mechanism is used to adjust the tilt angle of the support plate. The plate-shaped workpiece is placed on the support plate, and the plate-shaped workpiece is fixed by the clamping mechanism. The tilt angle of the support plate is adjusted by the angle adjustment mechanism so that the machining surface of the plate-shaped workpiece is offset from the cross section of the CNC milling machine's milling cutter. The end mill is controlled to feed along the inclined direction of the machined surface of the plate-shaped workpiece to mill an arc groove on the machined surface of the plate-shaped workpiece.

[0010] According to some embodiments of the present invention, the angle adjustment mechanism includes an angle sensor, a controller, and a drive assembly. The angle sensor is used to monitor the tilt angle of the support plate. The controller is electrically connected to the angle sensor and the drive assembly. The controller is used to receive the angle information monitored by the angle sensor and control the drive assembly to drive the support plate to swing up and down to adjust the tilt angle. The step of adjusting the tilt angle of the support plate using an angle adjustment mechanism to offset the machining surface of the plate-shaped workpiece from the cross-section of the CNC milling machine's milling cutter includes the following steps: Based on the required depth of the arc groove, the controller calculates the required tilt angle of the support plate; Based on the required tilt angle of the support plate, the controller controls the drive assembly to drive the support plate to swing up and down to adjust the support plate to the required tilt angle.

[0011] The advantages are: the present invention achieves precise control of the tilt angle of the support plate through the automated angle adjustment of the angle sensor, controller and drive components, reduces manual setting errors, and improves processing consistency and reliability. At the same time, the controller automatically calculates the tilt angle based on the groove depth requirement of the arc groove, realizes intelligent parameter adjustment, ensures processing accuracy and repeatability, and is suitable for plate-shaped workpieces of different processing specifications.

[0012] According to some embodiments of the present invention, the controller calculates the required tilt angle of the support plate based on the groove depth requirement of the arc groove, including the following steps: The depth of the circular arc groove is set to Obtain the radius parameter of the end mill. ; According to the formula Calculate the tilt angle of the support plate. .

[0013] The advantages are: by using a formula to calculate the tilt angle of the support plate, the groove depth and the radius of the milling cutter are parameterized, ensuring the accuracy and scientific nature of the support plate angle setting, avoiding reliance on experience, and improving machining accuracy. At the same time, this calculation step makes the machining process predictable and controllable, reducing trial and error costs, and is especially suitable for machining arc grooves with high precision requirements.

The fixed seat is fixed on the support plate, and the second cylinder is fixed on the fixed seat. The second cylinder is used to drive the top block to move back and forth along the inclined direction of the support plate, so that the top block presses and releases the upper side of the plate-shaped workpiece along the inclined direction of the support plate. The step of placing the plate-shaped workpiece on the support plate and fixing the plate-shaped workpiece using a clamping mechanism includes the following steps: The plate-shaped workpiece is placed on the support plate, so that the lower side of the plate-shaped workpiece along the inclined direction of the support plate is attached to the first positioning plate. The second cylinder is controlled to drive the top block to press the plate-shaped workpiece against the upper side of the support plate along the inclined direction.

[0021] The advantages are: the clamping assembly of the present invention, through the structure of the first positioning plate and the top block, ensures the accurate positioning and firm clamping of the plate-shaped workpiece on the inclined support plate, preventing the workpiece from sliding or shifting during processing. At the same time, the second cylinder drives the top block to press the workpiece, realizing rapid clamping and release, improving clamping efficiency, and is suitable for continuous production.

At the same time, the controller automatically calculates the tilt angle based on the groove depth requirement of the arc groove 150, realizing intelligent parameter adjustment, ensuring processing accuracy and repeatability, and is suitable for plate-shaped workpieces 140 with different processing specifications.

[0052] Reference Figure 6 , Figure 7 and Figure 8 Furthermore, in step S230 of some embodiments, based on the groove depth requirement of the arc groove 150, the controller calculates the required tilt angle of the support plate 110, including the following steps: Step S231, set the groove depth of the arc groove 150 to be... Obtain the radius parameters of the 160mm face milling cutter. .

The first cylinder 280 is used to drive the pressure block 270 to press and release the fixed plate 260, so that the locking assembly 250 can fix and release the support plate 110.

[0058] It is understood that this embodiment uses a locking component 250 to fix the support plate 110 via a pressure block 270 and a first cylinder 280. This prevents the support plate 110 from vibrating or shifting during processing, and avoids the thread gap between the first screw 210 and the second seat 240 during self-locking, which could cause the support plate 110 to vibrate or shift under force during processing. This ensures processing stability and the shape accuracy of the arc groove 150. At the same time, the arc groove 290 design allows the support plate 110 to swing freely within the adjustment range, while providing a firm fixation after locking, thus improving the safety and reliability of the equipment. In addition, the controller is electrically connected to the locking component 250, realizing automatic locking and releasing, which simplifies the operation process.
