Description

Technical Field

[0001] This utility model relates to the field of fiber laser tube cutting technology, and more specifically, to a fiber laser tube cutting machine. Background Technology

[0002] Laser cutting uses the energy released when a laser beam is irradiated onto the surface of a workpiece to melt and evaporate the workpiece, thereby achieving the purpose of cutting and engraving. It features high precision, fast cutting speed, no limitation on cutting patterns, automatic layout to save materials, smooth cuts, and low processing costs.

[0003] Common fiber laser tube cutting machines can only cut tubes, but lack the function of fixing the tubes. In actual tube cutting operations, the position of the tubes needs to be fixed by clamps. When switching between cutting round and square tubes, the clamps that fix the shape are difficult to effectively and securely hold tubes of different shapes, which ultimately leads to the problem of reduced tube fixation compatibility.

[0004] In summary, to ensure the compatibility of pipe fittings, it is necessary to address the issue that the fixed-shape clamps cannot be adapted to round or square pipes, so that the clamps can be adjusted according to the shape of the pipe fittings when switching between round and square pipes for cutting. Utility Model Content

[0005] The fiber laser tube cutting machine provided by this utility model aims to solve the problem that when switching between cutting round and square tubes, the clamp with a fixed shape is difficult to effectively and stably hold tubes with different shapes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiber laser tube cutting machine, including a worktable, on which a synchronous reverse horizontal displacement power mechanism is provided, and two tube fixing plates are provided on the synchronous reverse horizontal displacement power mechanism. Four strip grooves are opened on the surface of the tube fixing plates, and telescopic rods are installed inside the strip grooves. A sliding block is installed at the telescopic end of the telescopic rod, and a rotating shaft is installed on the surface of the sliding block. A right-angle clamp is installed at the end of the rotating shaft away from the sliding block, and an arc-shaped clamp is installed on the surface of the right-angle clamp. A tube cutting mechanism is provided on the worktable.

The synchronous reverse horizontal displacement power mechanism is used to control the synchronous reverse horizontal displacement of the two pipe fitting fixing plates. The synchronous reverse horizontal displacement power mechanism includes a drive assembly and a thread assembly. The output end of the drive assembly is connected to the thread assembly. The drive assembly is used to control the rotational movement of the thread assembly. The output end of the thread assembly is connected to the pipe fitting fixing plate. The thread assembly is used to control the synchronous reverse horizontal displacement of the two pipe fitting fixing plates.

[0008] In a preferred embodiment, the drive assembly includes a first mounting frame mounted on the upper end of the workbench and a first motor mounted on the outside of the first mounting frame.

[0009] In a preferred embodiment, the threaded assembly includes a bidirectional lead screw mounted on the output end of a first motor and a drive plate mounted on the outside of the bidirectional lead screw. The first motor is used to control the rotational movement of the bidirectional lead screw, and the connecting end of the drive plate is connected to the pipe fitting fixing plate.

[0010] In a preferred embodiment, the pipe cutting mechanism is used to cut the pipe. The pipe cutting mechanism includes a unidirectional horizontal displacement component and a telescopic component. The output end of the unidirectional horizontal displacement component is connected to the telescopic component. The unidirectional horizontal displacement component is used to control the horizontal displacement of the telescopic component, and the telescopic component is used to control the position of laser emission.

Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figures 1 to 5 A fiber laser tube cutting machine includes a worktable 1. A synchronous reverse horizontal displacement power mechanism is provided on the worktable 1. Two tube fixing plates 11 are provided on the synchronous reverse horizontal displacement power mechanism. Four strip grooves 12 are opened on the surface of the tube fixing plates 11. Telescopic rods 13 are installed inside the strip grooves 12. A sliding block 14 is installed at the telescopic end of the telescopic rod 13. A rotating shaft 15 is installed on the surface of the sliding block 14. A right-angle clamping plate 16 is installed at the end of the rotating shaft 15 away from the sliding block 14. An arc-shaped clamping plate 17 is installed on the surface of the right-angle clamping plate 16. A tube cutting mechanism is provided on the worktable 1.

[0024] It should be noted that the four strip grooves 12 are radially and symmetrically opened on the surface of the pipe fixing plate 11. The four telescopic rods 13 and their connected sliding blocks 14, rotating shafts 15, right-angle clamps 16 and arc-shaped clamps 17 together constitute an adaptive clamping unit. The combination design of right-angle clamps 16 and arc-shaped clamps 17 is the core of this solution. The right-angle concave surface of right-angle clamps 16 adapts to the corners of the pipe, and the arc surface of arc-shaped clamps 17 adapts to the outer wall of the round pipe, so as to achieve the compatible fixation of irregular pipe fittings by a single clamp.

[0025] It is worth noting that the rotating shaft 15 allows the right-angle clamp 16 and the arc-shaped clamp 17 to rotate in the horizontal plane. When clamping a square tube, it can be rotated so that the right-angle notch of the right-angle clamp 16 is aligned with the corner of the tube. When clamping a round tube, it can be rotated so that the arc surface of the arc-shaped clamp 17 fits the outer circle of the tube, which significantly improves the versatility and clamping efficiency of the fixture.

[0026] Refer to the instruction manual appendix Figures 1 to 4 The output end of the synchronous reverse horizontal displacement power mechanism is connected to the pipe fitting fixing plate 11. The synchronous reverse horizontal displacement power mechanism is used to control the synchronous reverse horizontal displacement of the two pipe fitting fixing plates 11. The synchronous reverse horizontal displacement power mechanism includes a drive assembly and a thread assembly. The output end of the drive assembly is connected to the thread assembly. The drive assembly is used to control the rotational movement of the thread assembly. The output end of the thread assembly is connected to the pipe fitting fixing plate 11. The thread assembly is used to control the synchronous reverse horizontal displacement of the two pipe fitting fixing plates 11.

[0027] It should be noted that the drive assembly provides power, and the thread assembly converts the rotational motion into the linear motion of the drive plate 222. The reverse thread design at both ends of the bidirectional lead screw 221 is key to ensure that the drive plates 222 at both ends always move synchronously in opposite directions when the lead screw rotates, thereby driving the two pipe fitting fixing plates 11 to move synchronously towards or away from each other.

[0028] Refer to the instruction manual appendix Figure 2 The drive assembly includes a first mounting frame 211 mounted on the upper end of the worktable 1 and a first motor 212 mounted on the outside of the first mounting frame 211.

[0029] It should be noted that the first mounting frame 211 provides a stable support base for the first motor 212 and the bidirectional lead screw 221, ensuring the stability of power transmission and the rigidity of the mechanism operation. The first motor 212 precisely controls the rotation angle and speed of the bidirectional lead screw 221, thereby achieving precise adjustment of the displacement of the pipe fitting fixing plate 11.

[0030] Refer to the instruction manual appendix Figures 2 to 3 The threaded assembly includes a bidirectional lead screw 221 installed at the output end of the first motor 212 and a drive plate 222 installed on the outside of the bidirectional lead screw 221. The first motor 212 is used to control the rotational movement of the bidirectional lead screw 221, and the connecting end of the drive plate 222 is connected to the pipe fixing plate 11.

[0031] It should be noted that the drive plate 222 is usually engaged with the reverse thread section of the double-acting screw 221 through a threaded hole. When the double-acting screw 221 rotates, the drive plate 222 moves linearly under the axial constraint of the screw. The rigid connection between the drive plate 222 and the pipe fitting fixing plate 11 ensures the synchronization of displacement and the effective transmission of force.

[0032] Refer to the instruction manual appendix Figures 1 to 5The pipe cutting mechanism is used to cut pipes. The pipe cutting mechanism includes a unidirectional horizontal displacement component and a telescopic component. The output end of the unidirectional horizontal displacement component is connected to the telescopic component. The unidirectional horizontal displacement component is used to control the horizontal displacement of the telescopic component, and the telescopic component is used to control the position of laser emission.

[0033] It should be noted that the unidirectional horizontal displacement component is responsible for controlling the axial movement of the cutting head to achieve fixed-length cutting of the pipe, while the telescopic component is responsible for controlling the radial distance of the cutting head relative to the surface of the pipe. The coordinated action of the two enables the fiber laser cutting head 324 to accurately position the cutting point of the pipe to be cut.

[0034] It is worth noting that this split design is simpler and more reliable than the integrated multi-axis linkage mechanism, and is sufficient to meet the straight-line cutting requirements of round and square tubes.

[0035] Refer to the instruction manual appendix Figures 2 to 5 The unidirectional horizontal displacement assembly includes a second mounting frame 311 mounted on the upper end of the worktable 1, a second motor 312 mounted on the outside of the second mounting frame 311, a unidirectional lead screw 313 mounted on the output end of the second motor 312, and a drive block 314 mounted on the outside of the unidirectional lead screw 313. The second motor 312 is used to control the rotational movement of the unidirectional lead screw 313.

[0036] It should be noted that the second mounting frame 311 functions similarly to the first mounting frame 211, providing support and protection. The second motor 312 drives the one-way lead screw 313 to rotate, and the drive block 314 converts the rotational motion of the one-way lead screw 313 into its own linear motion. The precision lead of the one-way lead screw 313 ensures the high precision of the horizontal displacement of the cutting head.

[0037] Refer to the instruction manual appendix Figure 5 The telescopic assembly includes a support rod 321 mounted on the upper end of the drive block 314, a mounting plate 322 mounted on the upper end of the support rod 321, a cylinder 323 mounted on the surface of the mounting plate 322, and a fiber laser cutting head 324 mounted on the output end of the cylinder 323. The cylinder 323 is used to control the horizontal movement of the fiber laser cutting head 324.

[0038] It should be noted that the support rod 321 and the mounting plate 322 form a cantilever structure, which lifts the cylinder 323 and the fiber laser cutting head 324 above the pipe. The cylinder 323 acts as an actuator, and the extension and retraction of its piston rod can quickly and directly adjust the focal position of the fiber laser cutting head 324 to adapt to different pipe diameters or cutting requirements.

[0039] Refer to the instruction manual appendix Figures 1 to 4 A spring 18 is installed on the side of the slider 14 near the telescopic rod 13. The end of the spring 18 away from the slider 14 is connected to the inner wall of the strip groove 12. A feeding groove 19 is provided at the upper end of the worktable 1.

[0040] It should be noted that the spring 18 is sleeved on the outside of the telescopic rod 13. When clamping the pipe fitting, the outer wall of the pipe fitting presses the right-angle clamping plate 16 or the arc-shaped clamping plate 17. The spring 18 and the telescopic rod 13 are compressed by the sliding block 14. The spring 18 provides a continuous elastic preload, so that the clamping plate can adapt to the slight difference in the size of the pipe fitting and fit tightly. At the same time, it plays a role in buffering and preventing overpressure. The discharge groove 19 is located below the two pipe fitting fixing plates 11, which facilitates the natural fall or auxiliary discharge of the cut pipe fitting segments or waste.

[0041] Working principle: First, place the pipe to be cut on the workbench 1, with both ends positioned between two pipe fixing plates 11. Start the first motor 212 to drive the bidirectional lead screw 221 to rotate. Since the bidirectional lead screw 221 has two sections with opposite threads, the two drive plates 222 on its outer side move horizontally in opposite directions, causing the two pipe fixing plates 11 to move towards each other until they initially approach the ends of the pipe. During the movement of the pipe fixing plates 11, the outer wall of the pipe will first contact one or more right-angle clamps 16 or arc-shaped clamps 17. Depending on the shape of the pipe, the pipe will push the contacting right-angle clamps 16 or arc-shaped clamps 17, forcing the sliding block 14 to slide along the axial direction of the telescopic rod 13 in the strip groove 12, while compressing the spring 18. If the pipe is square, its edges will be embedded in the right-angle recesses of the right-angle clamps 16; if the pipe is round, its outer wall will... The inner arc surface of the curved clamping plate 17 is fitted. During this process, the rotating shaft 15 allows the right-angle clamping plate 16 and the curved clamping plate 17 to rotate in the horizontal plane according to the shape of the pipe fitting, adjusting to the optimal clamping angle. The elastic restoring force provided by the spring 18 keeps the sliding block 14, the right-angle clamping plate 16 and the curved clamping plate 17 in close contact with the surface of the pipe fitting, achieving a stable and adaptive clamping. After clamping is completed, the pipe cutting mechanism is started. The second motor 312 drives the one-way lead screw 313 to rotate, driving the drive block 314 to move in the horizontal direction. Then, through the support rod 321 and the mounting plate 322, the entire telescopic assembly is moved to the position where the pipe fitting needs to be cut. Subsequently, the cylinder 323 is activated, pushing the fiber laser cutting head 324 to move horizontally. During this process, the fiber laser cutting head 324 emits a laser beam to complete the cutting of the pipe fitting. The cut pipe section or waste can be discharged through the feeding trough 19.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
