Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a dynamic oscillation mechanism for laser cutting of beveled pipes. Background Technology

[0002] In existing technologies, straight pipe intersection line cutting devices and bent pipe intersection line cutting devices are usually set up independently. For pipe laser cutting, traditional cutting can only achieve horizontal and vertical movement. However, when welding pipes, it is often necessary to cut a port with a certain bevel angle to meet the welding process requirements. However, existing laser cutting mechanisms cannot achieve oscillating bevel cutting because the laser head cannot meet the bevel angle cutting requirements of welded pipes. In some pipe welding scenarios that require high-strength connections, the connection strength and sealing performance of pipes without a suitable bevel angle are difficult to guarantee after welding, which can easily lead to safety hazards. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where laser heads cannot perform oscillating beveling cuts and thus cannot meet the requirements for beveling angle cuts of welded pipes. The proposed invention is a dynamic oscillation mechanism for laser cutting of beveling pipes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The design includes a dynamic oscillation mechanism for laser cutting of bent pipes with beveling, comprising a support frame fixedly connected to the body of a laser cutting machine, a horizontal drive motor fixedly connected to the upper end of the support frame, a first movable frame connected to the horizontal drive motor, a first motor fixedly connected to the first movable frame, a first fixed plate fixedly connected to the output end of the first motor, a mounting base fixedly connected to the first fixed plate, a laser cutting gun head connected to the mounting base, and a fixing mechanism for limiting the bending of the pipe on the ground.

[0005] Preferably, the first motor is a servo motor.

[0006] Preferably, the fixing mechanism includes a base frame, which is set on the ground. A lifting mechanism is connected inside the base frame, a second movable frame is connected to the lifting mechanism, a linear motor is connected to the second movable frame, a third movable frame is connected to the output end of the linear motor, and a deflection mechanism is fixedly connected to the third movable frame.

[0007] Preferably, the base frame is coated with an anti-corrosion layer.

[0008] Preferably, the deflection mechanism includes a second motor, which is fixedly connected to a third movable frame. The output end of the second motor is fixedly connected to a second fixed plate, and a mounting component is fixedly connected to the second fixed plate. A bent pipe is connected to the mounting component.

[0009] Preferably, the second fixing plate and the mounting component are an integral structure.

[0010] The dynamic oscillation mechanism for laser cutting of bent pipe beveling proposed in this utility model has the following advantages: According to the requirements of laser cutting for beveling pipes, after the first motor is powered on and started, it drives the first fixed plate to rotate. The first fixed plate drives the laser cutting gun head to rotate through the mounting base, thereby adjusting the cutting angle of the laser cutting gun head and thus meeting the laser cutting requirements of different angles for beveling pipes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example 1: Refer to Figure 1-3The dynamic oscillation mechanism for laser cutting of beveled pipes includes a support frame 1, which is fixedly connected to the laser cutting machine body 2. A horizontal drive motor 3 is fixedly connected to the upper end of the support frame 1. A first movable frame 4 is connected to the horizontal drive motor 3. A first motor 5, which is a servo motor, is fixedly connected to the first output end of the first motor 5. A first fixed plate 6 is fixedly connected to the first fixed plate 6. A mounting base 7 is fixedly connected to the first fixed plate 6. A laser cutting gun head 8 is connected to the mounting base 7. A fixing mechanism 10 for limiting the bending of the pipe 9 is provided on the ground.

[0015] Work process: The bent pipe 9 is fixed on the fixing mechanism 10. After the horizontal drive motor 3 is started, it drives the first movable frame 4 to move in the horizontal direction. The first movable frame 4 drives the first motor 5 to move. The first motor 5 drives the mounting base 7 to move through the first fixed plate 6. The mounting base 7 drives the laser cutting gun head 8 to move in the horizontal direction. The horizontal position of the laser cutting gun head 8 is adjusted. After the position of the laser cutting gun head 8 is determined, the horizontal drive motor 3 stops working. According to the laser cutting requirements for beveling the pipe 9, after the first motor 5 is powered on and started, it drives the first fixed plate 6 to rotate. The first fixed plate 6 drives the laser cutting gun head 8 to rotate through the mounting base 7, thereby adjusting the cutting angle of the laser cutting gun head 8 to meet the laser cutting requirements of different angles for beveling the pipe 9.

[0016] Example 2: Refer to Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the fixing mechanism 10 includes a base frame 101, which is set on the ground.

A deflection mechanism 106 is fixedly connected to the third movable frame 105. The deflection mechanism 106 includes a second motor 1061, which is fixedly connected to the third movable frame 105. The output end of the second motor 1061 is fixedly connected to a second fixed plate 1062. A mounting component 1063 is fixedly connected to the second fixed plate 1062. The second fixed plate 1062 and the mounting component 1063 are an integral structure. A bent pipe 9 is connected to the mounting component 1063. The bent pipe 9 is fixed on the mounting piece 1063. After the lifting mechanism 102 is started, it drives the second movable frame 103 to move vertically and adjust the height of the bent pipe 9. After the linear motor 104 is started, it drives the third movable frame 105 to move horizontally and adjust the horizontal position of the bent pipe 9. After the second motor 1061 is powered on and started, it drives the second fixed plate 1062 to rotate. The second fixed plate 1062 drives the mounting piece 1063 to rotate, and the mounting piece 1063 drives the bent pipe 9 to rotate and adjust the cutting position of the bent pipe 9.
