Description

Technical Field

[0001] This invention relates to the field of cutting equipment, and more particularly to a cutting equipment for the intersection line of ship section closure pipes with multi-axis linkage control. Background Technology

[0002] As is well known, in the shipbuilding industry, intersecting line cutting equipment with multi-axis linkage control plays a crucial role, mainly for intersecting line cutting of ship section closure pipes.

[0003] For example, the authorization announcement number is CN102806404B, the authorization announcement date is January 21, 2015, and the name is "A Pipe Intersection Line Cutting Device". It includes a support and a control device. The support has a support cylinder, and the outer surface of the support cylinder has an annular circumferential guide rail. A connecting seat is provided on the circumferential guide rail. A servo-driven rotary drive device is provided between the connecting seat and the support cylinder to drive the connecting seat to slide along the circumferential guide rail. A longitudinal guide rail parallel to the center line of the support cylinder is provided on the connecting seat. A cutting tool fixing device is slidably provided on the longitudinal guide rail. A servo-driven longitudinal drive device is provided on the connecting seat to drive the cutting tool fixing device to slide along the longitudinal guide rail. The rotary drive device and the longitudinal drive device are connected to the control device.

[0004] As in the aforementioned application, in existing cutting equipment, before performing intersecting line cutting on segmented and joined pipes, the pipe body needs to be fixed. However, due to the structural characteristics of the pipe body, namely its cylindrical shape, if the same fixing structure is used to fix pipe bodies of different diameters, the axial position of the pipe body cannot be fixed. This makes it difficult to accurately obtain the position of the pipe body relative to the cutting mechanism of the equipment, thereby increasing the difficulty of subsequent intersecting line cutting and affecting cutting efficiency and cutting quality. Summary of the Invention

[0005] (I) Purpose of the Invention

[0006] In view of this, the purpose of this invention is to propose a ship section closure pipe intersection line cutting device with multi-axis linkage control. When the pipe to be cut is locked and fixed by the locking unit, the pipe to be cut can be automatically centered. Therefore, the position of the pipe to be cut relative to the cutting mechanism is easier to obtain, which facilitates subsequent precise cutting. Furthermore, through the structural design of the locking unit, the locking unit is more stable when locking and fixing the pipe to be cut, and the locking unit as a whole does not affect the installation of the pipe to be cut.

[0007] (II) Technical Solution

[0008] To achieve the above technical objectives, this invention provides a ship section closure pipe intersection line cutting device with multi-axis linkage control, comprising a base frame, a pipe fixing mechanism, and a cutting mechanism. The pipe fixing mechanism comprises two sets, respectively installed above both ends of the base frame, for fixing the pipe to be cut. The pipe fixing mechanism can slide along the length direction of the base frame. The cutting mechanism is located above the base frame and can slide along the length direction of the base frame, for performing intersection line cutting on the fixed pipe. The pipe fixing mechanism includes a fixing component, which includes an outer ring body and an inner ring body sleeved within the outer ring body. The inner ring body has a circular ring structure, and a locking unit for locking and positioning the pipe to be cut is installed on the inner side of the inner ring body.

[0011] As a further description of the above technical solution: the side of the clamp that contacts the tube to be cut is an arc-shaped surface, and the clamp is movably installed. Based on this, when the clamp is used to clamp tubes of different diameters, the clamp can move so that both sides of its edges can remain in contact with the tube to be cut, achieving a "lock" on the tube to be cut. Therefore, the locking effect of the clamp on the tube to be cut can be significantly improved, thereby ensuring the stability of the tube to be cut during the cutting process. In addition, this allows the device to be used for tubes of different diameters, improving the applicability of the device.

[0012] As a further description of the above technical solution: the clamp is rotatably mounted between two movable arms via a rotating shaft. The inner sides of the two movable arms are provided with arc-shaped grooves. The arc center of the arc-shaped grooves coincides with the axis of the rotating shaft. Both ends of the clamp are equipped with sliding protrusions. The sliding protrusions are slidably engaged in the arc-shaped grooves. A spring is provided between the inner wall of one end of the arc-shaped groove and the sliding protrusion.

[0016] As a further description of the above technical solution: the cutting mechanism includes a support frame, a vertical frame, a horizontal frame, and a laser cutter. The support frame is installed above one side of the base frame and can slide along the length of the base frame. The vertical frame is fixedly installed above the support frame.

The bracket is disposed above the base frame, and the top of the bracket has an arc-shaped structure. The mounting frame is fixed to the upper surface of the base frame and located below the bracket.

[0018] In the above technical solution, the present invention provides a ship section closure pipe intersection line cutting device with multi-axis linkage control. The structure used to fix the pipe body to be cut in the cutting device adopts a pipe body fixing mechanism. The inner ring of the pipe body fixing mechanism adopts a circular ring structure and can move along the length direction on the base frame. Therefore, the pipe body fixing mechanism can fix the pipe body to be cut at different positions according to the cutting requirements, which facilitates cutting.

[0019] When the inner ring of this cutting equipment locks and fixes pipes of different models and diameters to be cut through the locking unit, it can achieve the effect of automatically centering the pipes to be cut. Therefore, the position of the pipes to be cut relative to the cutting mechanism is easier to obtain, which facilitates precise cutting. Furthermore, through the structural design of the locking unit, the locking unit is more stable when locking and fixing the pipes to be cut, and the locking unit as a whole does not affect the installation of the pipes to be cut.

[0040] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0041] Example 1

[0042] like Figures 1-15 As shown: This embodiment provides a technical solution: a ship section closure pipe intersection line cutting device with multi-axis linkage control, including a base frame 1, a pipe fixing mechanism 2 and a cutting mechanism 3. The pipe fixing mechanism 2 is provided in two sets, which are respectively installed above the two ends of the base frame 1 for fixing the pipe to be cut. The pipe fixing mechanism 2 can slide along the length direction of the base frame 1. The cutting mechanism 3 is set above the base frame 1 and can slide along the length direction of the base frame 1 for intersecting line cutting of the fixed pipe to be cut. The pipe fixing mechanism 2 includes a fixing component 20, which includes an outer ring body 200 and an inner ring body 202 sleeved inside the outer ring body 200. The inner ring body 202 adopts a circular ring structure, and a locking unit for locking and positioning the pipe to be cut is installed on the inner side of the inner ring body 202.

[0043] Working principle: First, the pipe to be cut is installed on the pipe fixing mechanism 2, so that both ends of the pipe to be cut are respectively inserted into the inner ring 202 of the two pipe fixing mechanisms 2. Then, according to the actual cutting needs, the positions of the two pipe fixing mechanisms 2 are adjusted so that the two pipe fixing mechanisms 2 are respectively located in the non-cutting area on the pipe to be cut. After completion, the pipe to be cut is locked and fixed by the locking unit. When the locking unit locks and fixes the pipe to be cut, the pipe to be cut is automatically centered, that is, located in the center of the inner ring 202. Finally, the cutting mechanism 3 is started, so that the cutting mechanism 3 moves to the cutting point on the pipe to be cut, and the pipe to be cut is cut, thus completing the cutting of the ship section intersection line of the device.

[0044] In summary, the structure used to fix the tube to be cut in this cutting equipment adopts the tube fixing mechanism 2. The inner ring 202 of the tube fixing mechanism 2 adopts a circular ring structure and can move along the length direction on the base frame 1. Therefore, the tube fixing mechanism 2 can fix the tube to be cut at different positions according to the cutting requirements, which facilitates cutting. At the same time, when the inner ring 202 locks and fixes the tube to be cut through the locking unit, the tube to be cut is automatically centered. Therefore, the position of the tube to be cut relative to the cutting mechanism 3 is easier to obtain, which facilitates subsequent precise cutting. It should be noted that the initial position of the cutting mechanism 3 is fixed, and the center position of the inner ring 202 is fixed. Before cutting, only the diameter of the tube to be cut needs to be input to obtain the position of the tube to be cut relative to the cutting mechanism 3, which facilitates cutting.

[0045] Specifically, such as Figures 6-15 As shown, in order to fix the tube to be cut, in this embodiment, a front cavity 2020 and a rear cavity 2021 are respectively provided on the front and rear sides of the inner ring 202. Multiple sets of locking units are installed. Each locking unit includes a rotating shaft 208, a movable arm 207, a clamp 206 and a drive unit. The rotating shaft 208 is rotatably inserted into the inner ring 202, and the two ends of the rotating shaft 208 extend into the front cavity 2020 and the rear cavity 2021 respectively. Two movable arms 207 are provided. The two movable arms 207 are located in the front cavity 2020 and the rear cavity 2021 respectively, and the ends of the two movable arms 207 are respectively sleeved on the two ends of the rotating shaft 208. The clamp 206 is installed between the front ends of the two movable arms 207. The drive unit is installed on the inner ring 202 and is used to control the movable arms 207 in the multiple sets of locking units to rotate synchronously, thereby locking or unlocking the tube to be cut.

[0046] Based on this, when the tube to be cut is inserted into the inner ring 202, the drive unit drives all the movable arms 207 in the locking units to rotate synchronously around the rotating shaft 208. At this time, the clamps 206 at the front end of all the movable arms 207 gradually rotate towards the center of the inner ring 202 until all the clamps 206 clamp the tube to be cut simultaneously from all angles, thus locking the tube to be cut. Conversely, when the movable arms 207 rotate in the opposite direction under the drive unit, the clamps 206 gradually move away from the inner ring. The center of body 202 unlocks the tube to be cut. Since all the movable arms 207 rotate synchronously, the relative distance between the clamp 206 at the front end of the movable arm 207 and the central axis of the inner ring body 202 is fixed. This ensures that when all the clamps 206 lock the tube to be cut, the tube to be cut can be directly positioned in the center. Thus, the device can automatically center the tube to be cut when locking it, so no other positioning structure is needed to center it.

[0047] Specifically, such as Figures 6-15 As shown, in order to achieve synchronous rotation control of all movable arms 207, in this embodiment, the movable arms 207 located inside the front cavity 2020 are provided with residual teeth 2070, which are located at the ends of the movable arms 207. A front cover 201 is installed on the outer ring body 200 at the front cavity 2020. The driving unit includes a rotating ring 209 and a fifth motor 2010. The rotating ring 209 is rotatably installed in the front cavity 2020, and the rotating ring 209 surrounds all the movable arms 207 in the front cavity 2020. The inner side of the rotating ring 209 is provided with a tooth corresponding to the position of each residual tooth 2070. The first toothed area 2090 engages, enabling the rotating ring 209 to drive all the movable arms 207 to rotate synchronously when it rotates. The fifth motor 2010 is fixedly installed on the outside of the front cover 201. The first gear 2011 is installed on the output shaft of the fifth motor 2010. The outer side of the rotating ring 209 is also provided with a second toothed area 2091, which meshes with the first gear 2011. Based on this, when the fifth motor 2010 runs, it can drive the first gear 2011 to rotate. Therefore, under the meshing action of the second toothed area 2091, the rotating ring 209 rotates, thereby driving all the movable arms 207 to rotate synchronously.

[0048] Specifically, such as Figures 6-15 As shown, in order to improve the locking effect of the clamp 206 on the tube to be cut, in this embodiment, the side of the clamp 206 that contacts the tube to be cut is an arc-shaped surface, and the clamp 206 is movably installed. Based on this, when the clamp 206 clamps tubes of different diameters, the clamp 206 can move so that both sides of its edges can keep in contact with the tube to be cut, thus achieving a "lock" on the tube to be cut. Therefore, the locking effect of the clamp 206 on the tube to be cut can be significantly improved, thereby ensuring the stability of the tube to be cut during the cutting process. In addition, this makes the device applicable to tubes of different diameters, improving the applicability of the device.

[0049] Specifically, such as Figure 14As shown, since the clip 206 is movably installed, in order to limit the movement of the clip 206 and avoid positional deviation when locking the tube to be cut, thus affecting the locking effect, in this embodiment, the clip 206 is rotatably installed between two movable arms 207 via a rotating shaft. An arc-shaped groove 2071 is provided on the inner side of the two movable arms 207, and the arc center of the arc-shaped groove 2071 coincides with the axis of the rotating shaft. Sliding protrusions 2060 are installed at both ends of the clip 206, and the sliding protrusions 2060 slide and engage within the arc-shaped groove 2071. A spring 2072 is provided between the inner wall of one end of the arc-shaped groove 2071 and the sliding protrusion 2060. Based on this, the spring 2072 can apply a spring force to the sliding protrusion 2060, causing the sliding protrusion 2060 to have a counterclockwise rotation tendency. Therefore, the clip 206, without being disturbed by other external forces, rotates by the spring force. Due to the elastic force of the spring 2072, the clamp 206 rotates counterclockwise to its limit position. The two sides of the arc-shaped surface of the clamp 206 are respectively designated as the first arc edge 206b and the second arc edge 206a. When the clamp 206 is in this limit position, the first arc edge 206b is located in the blocking area of ​​the two movable arms 207, and the second arc edge 206a is located in the outer area of ​​the two movable arms 207. At this time, when the movable arms 207 gradually rotate counterclockwise to lock the tube to be cut, the second arc edge 206a will first contact the surface of the tube to be cut. Then the movable arms 207 continue to rotate. Because the second arc edge 206a is squeezed by the tube to be cut, the clamp 206 as a whole will rotate until the first arc edge 206b also rotates to contact the tube to be cut, and cooperates with the second arc edge 206a to "lock" the tube to be cut.

[0050] It should be noted that if the movement of the clips 206 is not restricted, as the clips 206 gradually move toward the tube to be cut, one side of the curved surface of each clip 206 will droop due to the influence of gravity. As a result, when locking the tube to be cut, the non-curved surface of the clips 206 will come into contact with the tube to be cut, thus failing to achieve the desired locking effect.

[0051] Specifically, such as Figures 6-15 As shown, in order to avoid the locking unit affecting the installation of the pipe to be cut, in this embodiment, the inner ring 202 has a receiving cavity 2022 corresponding to the number of clips 206. The clips 206 can be completely accommodated in the receiving cavity 2022 by the rotation of the movable arm 207. This structural arrangement ensures that when installing the pipe to be cut, the clips 206 can be completely accommodated in the receiving cavity 2022, so as not to affect the installation of the pipe to be cut.

[0052] Specifically, such as Figures 6-15As shown, in order to allow the tube to be cut to rotate after locking for easy cutting, in this embodiment, a slide 21 is installed at the bottom of the outer ring 200. A sixth motor 213 is fixedly installed on the slide 21 on one side of the rear cavity 2021 via a frame 216. A second gear 212 is installed on the output shaft of the sixth motor 213. The inner ring 202 is rotatably installed inside the outer ring 200. A connecting ring frame 20 is fixedly installed on the inner ring 202 on the outer side of the rear cavity 2021 via bolts. 5. A toothed ring 204 is fitted onto the connecting ring frame 205. A rear cover 203 is installed on the outer side of the outer ring body 200, covering the toothed ring 204. The bottom of the rear cover 203 has an opening. The second gear 212 meshes with the toothed ring 204 through the opening. Based on this, when the sixth motor 213 is running, the meshing action of the second gear 212 and the toothed ring 204 can cause the connecting ring frame 205 to drive the inner ring body 202 to rotate, thereby driving the tube to be cut to rotate, which facilitates cutting.

[0053] Specifically, such as Figures 6-15 As shown, in order to achieve the movement control of the pipe fixing mechanism 2, in this embodiment, a first guide groove 11 is provided on the upper surface of the base frame 1 along the length direction. A first lead screw 211 is rotatably installed inside the first guide groove 11 along the length direction. A first motor 210 is installed at one end of the base frame 1. The output shaft of the first motor 210 is connected to one end of the first lead screw 211. A first sliding member 215 is installed at the bottom of the slide 21. A lead screw nut adapted to the first lead screw 211 is nested inside the first sliding member 215. The first sliding member 215 is slidably assembled. Within the first guide groove 11, the lead screw nut is sleeved with the first lead screw 211. Based on this, when the first motor 210 runs, it can drive the first lead screw 211 to rotate. Under the cooperation of the lead screw nut, the slide 21 slides along the length direction of the base frame 1, thereby realizing the movement control of the tube fixing mechanism 2. It should also be noted that the bottom of the slide 21 is also equipped with a first limiting slider 214. The upper surface of the base frame 1 is provided with a first limiting groove 10 along the length direction, and the first limiting slider 214 is slidably installed in the first limiting groove 10.

[0054] Specifically, such as Figures 1-5 As shown, in order to cut the pipe to be cut, in this embodiment, the cutting mechanism 3 includes a support frame 33, a vertical frame 32, a horizontal frame 31 and a laser cutter 30. The support frame 33 is installed above one side of the base frame 1 and can slide along the length of the base frame 1. The vertical frame 32 is fixedly installed above the support frame 33. A vertical plate 320 is slidably installed on one side of the support frame 33 and can slide in the vertical direction. One end of the horizontal frame 31 is fixed on the vertical plate 320. A mounting plate 310 is installed at the bottom of the horizontal frame 31 and can slide in the horizontal direction. The laser cutter 30 is fixedly installed below the mounting plate 310.

[0055] Based on this, the laser cutter 30 can move and adjust its position along the length, width, and height of the base frame 1, thereby achieving cutting of the pipeline to be cut in the X, Y, and Z axes.

[0056] Specifically, the upper surface of the base frame 1 is provided with a second limiting groove 13 along its length, and the side of the base frame 1 is provided with a second guide groove 12 along its length. A second lead screw 333 is rotatably installed in the second guide groove 12 along its length. A second motor 332 is installed at one end of the base frame 1. The output shaft of the second motor 332 is connected to one end of the second lead screw 333. The support frame 33 adopts an inverted L-shaped structure. A second limiting slider 330 is installed below the horizontal end of the support frame 33. The second limiting slider 330 is slidably assembled in the second limiting groove 13. A second sliding member 331 is installed on the inner side of the vertical end of the support frame 33. The second sliding member 331 is slidably assembled in the second guide groove 12. A lead screw nut that is adapted to and sleeved with the second lead screw 333 is embedded inside the second sliding member 331. Based on this, when the second motor 332 runs, it drives the second lead screw 333 to rotate.
