Description

Technical Field

[0001] This utility model relates to the technical field of laser cutting devices, and in particular to a laser cutting device for a sailboat model mast. Background Technology

[0002] In the field of sailboat model making, the mast, as a key structural component, is usually made of a slender cylindrical rod. Its machining accuracy and surface quality directly affect the overall performance and aesthetics of the model. Currently, laser cutting technology is often used for cutting such cylindrical workpieces because of its advantages such as high precision, non-contact processing and small heat-affected zone.

[0003] However, existing laser cutting equipment still faces significant technical bottlenecks when processing cylindrical mast-like workpieces. Specifically, current laser cutting equipment typically uses clamps to hold and fix the workpiece at both ends to ensure its stability during the cutting process. However, after the laser completes a cut, the cut end of the workpiece becomes suspended due to the loss of its original support, preventing it from being cut or trimmed again at the same workstation. If further processing is required, the operator must remove the cut workpiece, re-clamp it, and calibrate its position, which not only significantly reduces processing efficiency but also easily introduces positioning errors, affecting processing consistency and finished product accuracy. Furthermore, frequent disassembly and reassembly increase operational complexity and labor costs, especially when mass-producing small sailboat model masts, where this problem is even more pronounced. Utility Model Content

[0004] In view of this, the present invention provides a laser cutting device for sailboat model masts, which can overcome the shortcomings of existing laser cutting devices where the cut end of the workpiece is suspended due to the loss of its original support after being cut, making it impossible for the workpiece to be further processed at the same workstation.

[0005] The technical solution is as follows: A laser cutting device for a sailboat model mast includes: a base; a clamping assembly disposed on the base for clamping the workpiece; a guide seat connected to the clamping assembly; a moving rod slidably connected to the inner side of the guide seat; a fixed clamp installed at the end of the moving rod; a moving assembly disposed on the guide seat for driving the moving rod to move; and a cutting assembly disposed on the base for cutting the workpiece.

[0006] Preferably, the clamping assembly includes: a fixed frame symmetrically connected to the top of the base; a sliding clamp symmetrically slidably connected to the inner side of the fixed frame, and a guide seat fixedly connected to the sliding clamp; and a two-way cylinder installed inside the fixed frame, with the telescopic rods on both sides of the two-way cylinder respectively connected to the sliding clamps on both sides.

[0007] Preferably, the moving component includes: a drive motor mounted on the top of the guide seat; a first friction wheel connected to the output shaft of the drive motor, the first friction wheel being located inside the guide seat and contacting the side of the moving rod; and a second friction wheel rotatably connected to the inside of the guide seat, the second friction wheel contacting the other side of the moving rod.

[0008] Preferably, the cutting assembly includes: a support frame symmetrically connected to the top of the base; an electric slide rail mounted on the support frame; and a laser cutting device mounted on the slider of the electric slide rail.

[0009] Preferably, the slide also includes a corrugated baffle, symmetrically connected to both ends of the guide rail of the electric slide rail, and the end of the corrugated baffle is connected to the side of the slider of the electric slide rail.

[0010] Preferably, it also includes a rotating roller that is symmetrically rotated and connected to a fixed clamp.

[0011] Preferably, it also includes: rubber pads symmetrically connected to the sides of the sliding clamp.

[0012] Preferably, it also includes: a discharge ramp, connected to the base, and the discharge ramp is located below the laser cutting equipment.

[0013] Preferably, it also includes a sponge pad connected to the inner bottom of the discharge slant frame.

[0014] Preferably, the device also includes: a support base symmetrically connected to the top of the base; and a support roller rotatably connected to the support base, wherein the support roller contacts the bottom of the moving rod.

[0015] The beneficial effects of this utility model are as follows: 1. This utility model uses a bidirectional cylinder to drive a sliding fixture and a fixed fixture that are staggered front and rear to adaptively clamp a cylindrical workpiece. With the help of a drive motor, the moving rod and the fixed fixture are driven to slide along the guide seat through the first friction wheel and the second friction wheel. This allows the fixed fixture to move quickly to both sides of the cut after the workpiece is cut to support and fix it, so that the workpiece can be cut continuously multiple times at the same station, which significantly improves the processing efficiency and positioning accuracy.

[0016] 2. This utility model uses an electric slide rail to drive the laser cutting equipment to move along the workpiece axis for precise cutting. At the same time, the corrugated baffles set at both ends of the guide rail adapt to the movement of the slider, effectively preventing foreign objects from entering the guide rail, ensuring the long-term reliability of the equipment, and reducing maintenance needs.

[0017] 3. This utility model uses a discharge slant frame in conjunction with a sponge pad to receive and buffer the falling material after the workpiece is cut, avoiding workpiece damage and noise. The support base and support roller provide continuous rolling support for the moving rod, ensuring the stability of the moving rod during reciprocating movement, and further enhancing the overall stability and service life of the device.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: A laser cutting device for the mast of a sailboat model, such as Figures 1-3 As shown, the assembly includes a base 1, a clamping component, a guide seat 5, a moving rod 6, a fixed clamp 7, a rotating roller 15, a moving component, and a cutting component. The base 1 is equipped with a clamping component for clamping the workpiece. The clamping component is connected to the guide seat 5. The moving rod 6 is slidably connected to the inner side of the guide seat 5. Fixed clamps 7 are connected to the opposite ends of the moving rods 6 on both the left and right sides. The fixed clamps 7 are V-shaped, and the front and rear fixed clamps 7 are staggered. When the front and rear fixed clamps 7 move to the opposite side, the angle between the front and rear fixed clamps 7 can be adjusted by controlling the moving distance of the staggered fixed clamps 7 on both sides to accommodate workpieces of different diameters. The upper and lower parts of each fixed clamp 7 are rotatably connected to the rotating roller 15. The guide seat 5 is equipped with a moving component for driving the moving rod 6 to move. The base 1 is equipped with a cutting component for cutting the workpiece.

[0024] like Figure 2As shown, the clamping assembly includes a fixed frame 2, a sliding clamp 3, a two-way cylinder 4, and a rubber pad 16. Fixed frames 2 are connected to the left and right sides of the top of the base 1. Sliding clamps 3 are symmetrically slidably connected to the inner sides of the two fixed frames 2. The guide seat 5 is fixedly connected to the lower part of the sliding clamp 3. The opposing sides of the sliding clamps 3 on the front and rear sides are both "V" shaped, and the "V" shaped sides of the sliding clamps 3 on the front and rear sides are also staggered. Similarly, by controlling the moving distance of the sliding clamps 3 on the front and rear sides, workpieces of different diameters can be clamped. Two-way cylinders 4 are installed on the lower inner side of the two fixed frames 2, and the telescopic rods on the front and rear sides of the two-way cylinders 4 are fixedly connected to the sliding clamps 3 on the front and rear sides respectively.

[0025] like Figure 3 As shown, the moving assembly includes a drive motor 8, a first friction wheel 9, and a second friction wheel 10. Each sliding clamp 3 is equipped with a drive motor 8 at its lower part. The output shaft of the drive motor 8 is connected to the first friction wheel 9, which is located inside the guide seat 5. Each sliding clamp 3 is rotatably connected to the lower part of the second friction wheel 10. The first friction wheel 9 and the second friction wheel 10 are in contact with the front and rear sides of the moving rod 6, respectively.

[0026] like Figure 1 As shown, the cutting assembly includes a support frame 11, an electric slide rail 12, a laser cutting device 13, and a corrugated baffle 14. The support frame 11 is symmetrically connected to the top rear side of the base 1. An electric slide rail 12 is installed between the tops of the two support frames 11. The laser cutting device 13 is installed on the slider of the electric slide rail 12. Corrugated baffles 14 are connected to both ends of the guide rail of the electric slide rail 12. The opposite ends of the corrugated baffles 14 on the left and right sides are respectively connected to the left and right sides of the slider of the electric slide rail 12.

[0027] When a cylindrical workpiece needs to be cut, the workpiece is first placed between the sliding clamps 3 on both the front and rear sides, which are also between the fixed clamps 7 on both the front and rear sides. Then, the sliding clamps 3 on both the front and rear sides are moved to opposite sides by the bidirectional cylinder 4. The sliding clamps 3 will drive the guide seats 5, moving rods 6, fixed clamps 7 and rotating rollers 15 on both the front and rear sides to move to opposite sides until the sliding clamps 3 on both the front and rear sides cooperate to clamp the workpiece. At the same time, the fixed clamps 7 and rotating rollers 15 will contact the outer surface of the workpiece, and the fixed clamps 7 can also clamp the workpiece. The rubber pads 16 are used to increase the friction between the sliding clamps 3 and the outer surface of the workpiece, thereby preventing the workpiece from loosening. Then, the laser cutting equipment 13 is moved left and right by the electric slide rail 12 to align the laser cutting equipment 13 with the position to be cut on the workpiece. Then, the laser cutting equipment 13 can be used to cut the workpiece. During the left and right movement of the laser cutting equipment 13, the corrugated baffles 14 on the left and right sides will adapt and extend accordingly. This ensures that the corrugated shield 14 always blocks the top of the electric slide rail 12 without affecting the movement of the laser cutting equipment 13, preventing foreign objects from entering the guide rail of the electric slide rail 12. Then, the first friction wheel 9 is driven to rotate by the drive motor 8. With the cooperation of the second friction wheel 10, the first friction wheel 9 drives the left and right moving rods 6, the fixed clamps 7 and the rotating roller 15 to move to opposite sides through the friction between the first friction wheel 9 and the moving rod 6. The rotating roller 15 can roll along the outer surface of the workpiece, so that the left and right moving rods 6 and the fixed clamps 7 can move more smoothly until the left and right fixed clamps 7 move to the left and right sides of the workpiece break, so that the fixed clamps 7 can hold the workpiece break. At this time, the fixed clamps 7 and the sliding clamps 3 can cooperate to clamp the two cut workpieces synchronously, so that the laser cutting equipment 13 can perform secondary cutting processing on the workpiece. Similarly, by adjusting the position of the fixed clamps 7 again, the laser cutting equipment 13 can perform multiple cutting processing on the workpiece.

[0028] like Figure 1 As shown, it also includes a discharge inclined frame 17 and a sponge pad 18. The discharge inclined frame 17 is connected to the front middle of the base 1. The top of the discharge inclined frame 17 is an open design, and the discharge inclined frame 17 is located below the laser cutting equipment 13. The inner bottom of the discharge inclined frame 17 is connected to the sponge pad 18. After the cut workpiece loses its support, it will fall into the discharge inclined frame 17 due to gravity. The sponge pad 18 is used to prevent the workpiece from directly hitting the inner bottom of the discharge inclined frame 17 and causing noise. Then the cut workpiece will roll forward along the inclined surface of the inner bottom of the discharge inclined frame 17 for discharge.

[0029] like Figure 1As shown, it also includes a support base 19 and a support roller 20. The support base 1 is connected to the left and right sides of the top of the base 1 at intervals. The upper part of each support base 19 is rotatably connected to the support roller 20, and the top of the support roller 20 contacts the bottom of the moving rod 6. During the movement of the moving rod 6 on the left and right sides, the moving rod 6 can drive the support roller 20 to rotate by the friction between the moving rod 6 and the support roller 20, so as not to affect the movement of the moving rod 6. The support roller 20 can always support the moving rod 6 to ensure that the moving rod 6 always remains stable.

[0030] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
