Detailed ways:

The present invention will be further described below in conjunction with the accompanying drawings.

1 and 2, the present invention is a five-axis laser cutting machine for groove cutting, including a cutting frame, an X-axis drive unit, a Y-axis drive unit, a Z-axis drive unit, an X-axis rotation motor, and a Y-axis rotation Motor and laser head, the X-axis drive unit is set on the cutting frame, the Y-axis drive unit is set at the free end of the X-axis drive unit, the Z-axis drive unit is set at the free end of the Y-axis drive unit, the X-axis rotating motor Set on the free end of the Z-axis drive unit, the Y-axis rotary motor is set on the free end of the X-axis rotary motor, and the laser head is set on the free end of the Y-axis rotary motor.

The X-axis drive unit 1 in the present invention is a chain sprocket drive or a rack and pinion drive. The Y-axis drive unit 2 is driven by electric slide rails, linear screws or pulleys. Z-axis drive unit 3 adopts electric slide rail or linear screw drive.

A flange 41 is fixed on the X-axis rotary motor 4, the flange 41 is fixed on the free end of the Z-axis drive unit 3, an angle steel 42 is fixed on the motor shaft of the X-axis rotary motor 4, and the Y-axis rotary motor 5 is fixed on the angle steel 42.

The working logic of the present invention for cutting the slope is:

1) Install the laser head 6 on the robotic arm, and enable the laser head to perform five-axis motion. The five-axis motion is: linear motion in the X-axis direction, linear motion in the Y-axis direction, linear motion in the Z-axis direction, and around the X-axis. Rotational motion and rotational motion around the Y-axis;

2) Path setting: Set the motion path of the laser head in the three directions of X-axis, Y-axis and Z-axis according to the shape of the desired workpiece;

3) Trajectory division: The motion path is divided according to the outer contour of the required workpiece. If the shape of the required workpiece is square, the motion path is divided into a linear trajectory in the X-axis direction and a linear trajectory in the Y-axis direction. The shape of the required workpiece is a special shape including a straight line and an arc, and the motion path is divided into a linear trajectory in the X or Y axis direction, and a composite arc trajectory in the X and Y axis directions;

4) Set the opening and closing of the laser head during the cutting process according to the divided trajectories: when the motion path includes linear trajectories in different directions or multiple trajectories with coexistence of straight lines and arcs, after the laser head completes cutting in one trajectory direction, the laser head is turned off , after turning to another track direction, the laser head is turned on and cutting;

The laser head is closed at the inflection point of each rail clip transformation, and will not start until the next track cutting, which can effectively ensure the quality of the workpiece section and avoid quality defects at the corners.

5) Bevel cutting: The metal sheet is placed horizontally on the cutting frame, the bevel angle in each track direction is determined according to the shape of the processed part, and then the rotation angle of the laser head around the X-axis direction in each track direction is set Or the rotation angle around the Y-axis direction, and finally through the cooperation between the X-axis, the Y-axis and the Z-axis, the groove cutting in each track direction is completed.

By adjusting the cutting angle of the laser head, the cutting of various groove structures can be realized.

The invention can realize the cutting section, fill the gap in the prior art, set the motion path according to the shape of the workpiece, and then divide the trajectory according to the set path, each continuous edge of the workpiece forms a trajectory, and then determine the direction of each trajectory In the process of batch cutting, when there is a defect in the quality of the profile, the problem can be found better and faster.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements can be made without departing from the principles of the present invention, and these improvements should also be regarded as the present invention. protected range.
