[0002] When manufacturing a yacht, a lot of hardware is needed, among which a large number of tubular hardware are needed. In order to obtain tubular hardware of appropriate length, the pipe fittings need to be cut to obtain pipe fittings of appropriate length.

[0003] In the prior art, a rotating tool holder can be used to cut the pipe. In this way, multiple blades can act simultaneously for cutting, ensuring the uniformity and consistency of the cutting surface, thereby improving the overall cutting quality. Therefore, the rotating tool holder method for cutting is widely used. However, in the actual cutting process, since the tool will generate friction with the pipe when cutting the pipe, this can easily cause the pipe cutting area and the tool to overheat, resulting in plastic deformation of the tool cutting part, thereby causing the cutting edge shape to change permanently, affecting the normal use of the tool, and the tool needs to be replaced.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

A cutting assembly 9 is provided on one side of the axis of the cutting tool holder 5, and a water injection assembly 8 for injecting water into the cutting assembly 9 is provided on the outside of the cutting tool holder 5. The water injection assembly 8 includes a storage rack 81 fixedly connected to the outer wall of the cutting tool holder 5, and a water pipe 82 is fixedly plugged into the side of the storage rack 81 away from the cutting tool holder 5. A push plate 83 is provided inside the storage rack 81, and an extrusion rod 84 is provided on the right side of the push plate 83. A hose 85 is fixedly plugged between the storage rack 81 and the through pipe 13. The extrusion assembly 7 is provided on the outside of the cutting tool holder 5. The cutting assembly 9 includes a sleeve 91 slidably connected to the bottom of the outer wall of the tube 13, and an O-ring is installed near the tube 13 to ensure the sealing performance between the sleeve 91 and the tube 13. A mounting frame 92 is fixedly connected to the side of the sleeve 91 away from the tube 13, and a knife shaft 93 is rotatably connected to the inner side of the mounting frame 92. A blade 94 is fixedly connected to the outer wall of the knife shaft 93, and a bellows 95 is fixedly connected to the inner side of the mounting frame 92 near the top of the blade 94. The extrusion assembly 7 includes a long plate 71 fixedly connected to the right side of the fixing ring 4. The right side of the long plate 71 is slidably connected with a connecting ring 72, the inner side of the connecting ring 72 is threadedly connected to the right side of the outer wall of the cutting tool holder 5, the outer wall of the push plate 83 is in contact with the inner wall of the storage rack 81, and a check valve 86 is installed inside the water pipe 82. The driving mechanism 6 includes a stepper motor 61 fixedly connected to the right side of the fixing ring 4, the output shaft of the stepper motor 61 passes through the fixing ring 4 and is fixedly connected with a gear 62, and the driving mechanism 6 also includes a gear ring 63 fixedly connected to the left side of the outer wall of the cutting tool holder 5, and the gear 62 is meshed with the gear ring 63.

[0033] The outer wall of the sleeve 91 is fixedly connected to a first piston 96, the outer wall of the first piston 96 is in contact with the inner wall of the fixed cylinder 10, the inner wall of the fixed cylinder 10 is fixedly connected to a fixing frame 97, a spring 98 is fixedly connected between the fixing frame 97 and the first piston 96, the outer wall of the sleeve 91 is slidably connected to the fixing frame 97, a connecting cylinder 99 is fixedly inserted on the right side of the fixed cylinder 10, a second piston 910 is arranged inside the connecting cylinder 99, the outer wall of the second piston 910 is in contact with the inner wall of the connecting cylinder 99, and a moving rod 911 is fixedly connected to the right side of the second piston 910.

[0034] By adopting the above technical solution, the stepper motor 61 is a motor that can control the speed and the direction of rotation. When cutting the pipe hardware manufactured for the yacht, the pipe hardware is passed through the inside of the cutting tool holder 5 and the right side of the pipe hardware is fixed by the clamping assembly 2. At this time, the output shaft of the stepper motor 61 rotates rapidly, so that the gear 62 rotates, and under the action of the engagement between the gear 62 and the gear ring 63, the gear ring 63 rotates, and the cutting tool holder 5 rotates accordingly. When the cutting tool holder 5 rotates, since the inner side of the connecting ring 72 is threadedly connected to the right side of the outer wall of the cutting tool holder 5, and under the limiting action of the long plate 71, when the cutting tool holder 5 rotates, the connecting ring 72 can move in the left and right directions, and at this time the connecting ring 72 moves to the side close to the fixed ring 4.

[0035] As the connecting ring 72 moves toward the side close to the fixed ring 4, the left side of the connecting ring 72 squeezes the moving rod 911, so that the moving rod 911 moves with the second piston 910 to the left. It should be noted that hydraulic oil is arranged inside the connecting cylinder 99 on the left side of the second piston 910. When the second piston 910 moves to the left, the hydraulic oil is pressed into the inside of the fixed cylinder 10. Under the action of the hydraulic oil pressure, the first piston 96 moves toward the direction close to the pipe fitting, so that the mounting frame 92, the knife shaft 93 and the blade 94 can be moved toward the direction close to the pipe fitting until the blade 94 contacts the outer wall of the pipe fitting to be cut.

[0036] After the blade 94 contacts the outer wall of the pipe to be cut, the output shaft of the stepper motor 61 is controlled to rotate at a slower speed, so that the cutting tool holder 5 can rotate with the cutting assembly 9, and the blade 94 partially rotates around the pipe to cut a circle of the pipe. When the blade 94 cuts the pipe, it is subjected to the friction of the pipe, and the blade 94 itself and the knife shaft 93 will rotate along the axis of the knife shaft 93. Under the action of the extrusion assembly 7, the mounting frame 92, the knife shaft 93 and the blade 94 move toward the pipe at a slower speed, so that the function of automatic feed can be realized. There is no need for manual feed operation during the cutting process, which can effectively improve the cutting efficiency. It should be noted that the thread pitch of the thread connection between the right side of the outer wall of the cutting tool holder 5 and the connecting ring 72 is small, and the cutting tool holder 5 rotates one circle to make the blade 94 move down one millimeter to ensure the cutting effect.

[0037] When the cutting is completed, the stepper motor 61 rotates quickly in the opposite direction to facilitate the connection ring 72 to move away from the moving rod 911. Under the elastic force of the spring 98, the mounting frame 92, the knife shaft 93 and the blade 94 can be reset to facilitate the next cutting.

[0038] There are multiple groups of cutting assemblies 9, and the amount of hydraulic oil inside the multiple cutting assemblies 9 is the same, ensuring that the left side of the connecting ring 72 squeezes the moving rod 911, and the blades 94 in each group of cutting assemblies 9 have the same feeding distance.

[0039] In the prior art, since the tool generates friction with the pipe when cutting the pipe, it is easy to cause the pipe cutting area and the tool to overheat, resulting in plastic deformation of the cutting part of the tool, thereby causing the shape of the cutting edge to change permanently. When the tool is damaged during use, it will affect the cutting efficiency. Therefore, the device is provided with a water injection component 8. In the cutting preparation stage, cold water is injected from the water pipe 82 into the storage rack 81 through an external water injection device. The check valve 86 is a mature prior art, which ensures that the water inside the storage rack 81 cannot be discharged from the water pipe 82. When cutting, under the action of the extrusion assembly 7, when the connecting ring 72 moves to the side close to the fixed ring 4, the connecting ring 72 squeezes the extrusion rod 84, so that the push plate 83 moves to the right, so that the water inside the push plate 83 is pressed into the inside of the hose 85, and enters from the hose 85 into the inside of the through tube 13, the sleeve 91 and the mounting frame 92, and then is discharged from the bellows 95, so as to facilitate the cooling of the blade 94, reduce the overheating of the blade 94 and the possible plastic deformation of the cutting part of the blade 94, thereby avoiding damage to the tool that affects the cutting efficiency.

[0040] A cooling hood 912 is fixedly connected to the side of the bellows 95 close to the blade 94, and a plurality of spray holes 913 are provided on the side of the cooling hood 912 close to the blade 94. A sponge pad 914 is fixedly connected to the side of the cooling hood 912 close to the blade 94, and the sponge pad 914 has the property of absorbing water. A sliding rod 915 is fixedly connected to the side of the cooling hood 912 away from the blade 94, and the sliding rod 915 is slidably connected to the mounting frame 92 on the side away from the cooling hood 912.

[0041] By adopting the above technical solution, the spray hole 913 opened in the cooling hood 912 is close to the blade 94, and the side of the sponge pad 914 close to the blade 94 will stick to the blade 94, the cold water discharged from the bellows 95 enters the cooling hood 912 and is discharged from the spray hole 913, the cooling hood 912 is close to the part of the blade 94 away from the cutting pipe, and when the blade 94 rotates due to the friction of the pipe when cutting the pipe, it is convenient for the sponge pad 914 to stick to various areas of the blade 94 for cooling, so that the cooling is uniform, the cooling effect is improved, and the damage of the blade 94 is further avoided.

[0042] The extrusion rod portion 84 includes a large rod 841 fixedly connected to the right side of the push plate 83, the inner wall of the large rod 841 is threadedly connected to a small rod 842, an electromagnetic valve 916 is installed inside the sleeve 91, and the outer wall of the small rod 842 is fixedly connected to a hexagonal block.

[0043] By adopting the above technical solution, the solenoid valve 916 is a mature existing technology, and its opening and closing can be remotely controlled. Before cutting, the solenoid valve 916 is closed first, and the hexagonal block is rotated by an external tool. Under the action of the threaded connection, the left side of the small rod 842 is moved away from the connecting ring 72, so that in the process of adjusting the blade 94 to make the blade 94 contact with the outer wall of the pipe to be cut, the connecting ring 72 is prevented from squeezing the small rod 842, thereby avoiding spraying water for cooling when not cutting, and reducing water waste. When the blade 94 contacts the outer wall of the pipe to be cut, the hexagonal block is rotated in the other direction by an external tool, and under the action of the threaded connection, the left side of the small rod 842 is adjusted to fit the connecting ring 72, and the solenoid valve 916 is closed and opened.

[0044] The right sides of the movable rod 911 and the small rod 842 are both rotatably connected with a ball 11, and the interior of the fixed ring 4 is provided with a roller 12 that rotates away, and the roller 12 is in contact with the cutting tool holder 5 away from the fixed ring 4. The design of the roller 12 and the ball 11 can reduce the friction generated during movement.

[0045] The clamping assembly 2 includes a slide plate 21 slidably connected to the top right side of the base frame 1, and a three-jaw chuck 22 is fixedly connected to the left side of the slide plate 21. The clamping assembly 2 also includes a servo motor 23 fixedly connected to the right side of the base frame 1, and the output shaft of the servo motor 23 is fixedly connected to a screw rod 24, and the outer wall of the screw rod 24 is threadedly connected to the bottom of the slide plate 21.

[0046] By adopting the above technical solution, the right side of the pipe can be clamped by the three-jaw chuck 22. After a pipe of suitable size is cut out, the output shaft of the servo motor 23 can be rotated to rotate the screw rod 24. Under the action of the threaded connection, the slide plate 21 moves to the left with the three-jaw chuck 22 and the pipe, and the next cutting is performed after adjusting to the appropriate cutting length. It should be noted that the axis center line of the three-jaw chuck 22 and the axis center line of the cutting tool holder 5 are on the same straight line.

[0047] The outer wall of the knife shaft 93 is fixedly connected with a plurality of L-shaped frames 917, and the L-shaped frame 917 is rotatably connected with a circular shaft 918 on one side close to the cooling cover 912, and the cooling cover 912 is fixedly connected with a limiting block 919 on one side close to the L-shaped frame 917, and the limiting block 919 has a chamfered corner on one side close to the L-shaped frame 917.

[0048] By adopting the above technical solution, it should be noted that the sponge pad 914 itself has a certain elasticity. As the blade 94 is subjected to the friction of the pipe when cutting the pipe, the sponge pad 914 itself and the knife shaft 93 will rotate along the axis of the knife shaft 93, so that the L-shaped frame 917 rotates. When the L-shaped frame 917 rotates close to the limit block 919 and squeezes the limit block 919, the cooling cover 912 can be moved toward the direction of the blade 94, thereby squeezing the sponge pad 914, so that the water with a higher temperature inside the sponge pad 914 is squeezed out. When the L-shaped frame 917 is away from the limit block 919, the cooling cover 912 is reset under the action of the elastic force of the sponge itself, so that the cooling cover 912 absorbs water with a lower temperature, thereby avoiding the sponge pad 914 from absorbing heat from the internal water when the sponge pad 914 dissipates heat for the blade 94. The high absorption temperature affects the cooling effect of the blade 94, thereby further preventing the blade 94 from being damaged. It should be noted that when the end of the sliding rod 915 away from the blade 94 is attached to the mounting frame 92, the sponge pad 914 is still attached to the blade 94.

[0049] Working principle: When cutting the pipe hardware for yacht manufacturing, the pipe hardware is passed through the inside of the cutting tool holder 5, and the right side of the pipe hardware is fixed by the clamping assembly 2. The output shaft of the stepper motor 61 rotates quickly, so that the gear 62 rotates, and under the action of the meshing of the gear 62 and the gear ring 63, the gear ring 63 rotates, and the cutting tool holder 5 rotates accordingly. Since the inner side of the connecting ring 72 is threadedly connected to the right side of the outer wall of the cutting tool holder 5, and under the limiting action of the long plate 71, the connecting ring 72 moves to the side close to the fixed ring 4, and the left side of the connecting ring 72 squeezes the moving rod 911, so that the moving rod 911 moves with the second piston 910 to the left, and the hydraulic oil is pressed into the interior of the fixed cylinder 10. Under the action of the hydraulic oil pressure, The first piston 96 moves toward the pipe fitting, so that the mounting frame 92, the knife shaft 93 and the blade 94 can move toward the pipe fitting until the blade 94 contacts the outer wall of the pipe fitting to be cut. At this time, the output shaft of the stepper motor 61 is controlled to rotate at a slower speed, so that the cutting tool holder 5 can rotate with the cutting assembly 9, and the blade 94 partially rotates around the pipe fitting to cut a circle of the pipe fitting. When the blade 94 cuts the pipe fitting, it is subjected to the friction force of the pipe fitting, and the blade 94 itself and the knife shaft 93 will rotate along the axis of the knife shaft 93. Under the action of the extrusion assembly 7, the mounting frame 92, the knife shaft 93 and the blade 94 move toward the pipe fitting at a slower speed, which can realize the function of automatic feed. There is no need for manual feed operation during the cutting process, which can effectively improve the cutting efficiency.

[0050] In the cutting preparation stage, cold water is injected into the storage rack 81 from the water pipe 82 through an external water injection device. When cutting, under the action of the extrusion assembly 7, when the connecting ring 72 moves to the side close to the fixed ring 4, the connecting ring 72 squeezes the extrusion rod 84, so that the push plate 83 moves to the right, so that the water inside the push plate 83 is pressed into the inside of the hose 85, and enters from the hose 85 into the inside of the through pipe 13, the sleeve 91 and the mounting frame 92, and then is discharged from the bellows 95, so as to facilitate cooling of the blade 94 and reduce the possibility of plastic deformation of the cutting part of the blade 94 due to overheating of the blade 94, thereby avoiding damage to the tool that affects the cutting efficiency.

[0051] The cold water discharged from the bellows 95 enters the cooling hood 912 and is discharged from the spray hole 913. The cooling hood 912 is close to the portion of the blade 94 away from the cutting pipe, and as the blade 94 rotates due to the friction of the pipe when cutting the pipe, the sponge pad 914 can fit various areas of the blade 94 for cooling, so that the cooling is uniform, the cooling effect is improved, and damage to the blade 94 is further avoided.

[0052] By adopting the above technical solution, it should be noted that the sponge pad 914 itself has a certain elasticity. As the blade 94 is subjected to the friction of the pipe when cutting the pipe, the sponge pad 914 itself and the knife shaft 93 will rotate along the axis of the knife shaft 93, so that the L-shaped frame 917 rotates. When the L-shaped frame 917 rotates close to the limit block 919 and squeezes the limit block 919, the cooling cover 912 can be moved toward the blade 94, thereby squeezing the sponge pad 914, so that the water with higher temperature inside the sponge pad 914 is squeezed out. When the L-shaped frame 917 is away from the limit block 919, the cooling cover 912 is reset under the action of the sponge's own elastic force, which makes it easier for the cooling cover 912 to absorb water with lower temperature, so as to avoid the sponge pad 914 cooling the blade 94. The internal absorbed water has a high heat absorption temperature and affects the cooling effect of the blade 94, thereby further preventing the blade 94 from being damaged.
