Description

Technical Field

[0001] The present invention belongs to the field of laser cutting, and in particular relates to a supporting device for laser cutting and laser cutting equipment. Background Art

[0002] Laser cutting equipment is a high-tech product that integrates CNC technology, laser cutting, and precision machinery. It is primarily used for cutting metal pipes such as round and square tubes, I-beams, and channels. Its cut surfaces are burr-free and dross-free, and it produces a variety of cutting patterns. Its professionalism, high efficiency, and cost-effectiveness make it the preferred equipment for the non-contact metal pipe processing industry.

[0003] However, the laser cutting support device of the existing laser cutting equipment avoids the movement of the chuck along the bed direction by moving vertically downward, thereby increasing the height of the bed, and further increasing the overall volume and occupied space of the equipment. Summary of the Invention

[0004] In view of the above problems, the embodiments of the present application provide a support device for laser cutting and a laser cutting device, which can reduce the space occupied by the laser cutting device in the direction of gravity, thereby reducing the installation space limitation of the laser cutting device.

[0005] In a first aspect, embodiments of the present application provide a support device for laser cutting, configured to position a tube before a chuck of a laser cutting device grips the tube. The device comprises a base, a swing arm mechanism, and a support mechanism. The swing arm mechanism is rotatably mounted on the base, with the axis of rotation of the swing arm mechanism parallel to the direction of gravity. The support mechanism is configured to position the tube, and the support mechanism is mounted on the swing arm mechanism. The swing arm mechanism has a first position and a second position. The support mechanism is configured such that: in the first position, its extension direction is perpendicular to the direction of motion of the chuck; in the second position, its extension direction is parallel to the direction of motion of the chuck.

[0006] Specifically, when it is necessary to load the laser cutting equipment through the laser cutting support device, the swing arm mechanism is adjusted to the first position so that the extension direction of the support mechanism is perpendicular to the movement direction of the chuck, thereby making the extension direction of the pipe parallel to the movement direction of the chuck, so that the chuck can grasp one end of the pipe; after the chuck of the laser cutting equipment grasps the pipe, the swing arm mechanism is adjusted to the second position so that the swing arm mechanism and the swing arm mechanism are located on one side of the chuck and parallel to the movement direction of the chuck, so as not to affect the movement of the chuck.

[0007] In the above technical solution, by rotatably setting the swing arm mechanism on the base, relative to the support device that moves the support mechanism along the direction of gravity so that the support mechanism avoids the movement path of the chuck, the laser cutting support device can avoid the movement of the chuck along the bed direction by rotating the swing arm mechanism, thereby effectively reducing the size of the support mechanism in the direction of gravity, reducing the overall volume and occupied space of the equipment. Moreover, on the projection surface perpendicular to the movement direction of the chuck, the positive projection of the swing arm mechanism in the second position can still partially or completely overlap with the positive projection of the base, so that the swing arm mechanism in the second position can still share part of the space with the base, thereby improving the structural compactness of the device and reducing the space waste of the device; at the same time, because the swing arm mechanism can drive the support mechanism to be located on the opposite outside of the laser cutting equipment when it is in the second position, it is convenient for workers to load the pipe when in the second position.

[0008] In some embodiments, the swing arm mechanism includes a mounting frame and a first driving member. The mounting frame includes a first body extending along the direction of gravity and a second body extending along the first direction. The first body is rotatably mounted on the base, and the support mechanism is mounted on the second body. The first direction is perpendicular to the direction of gravity. The first driving member is configured to drive the first body to rotate.

[0009] In the above technical solution, by providing the mounting frame with a first body extending along the direction of gravity and a second body extending along the first direction, the volume of the space occupied by the mounting frame as a whole in the direction of gravity and the first direction is reduced, and the mass of the mounting frame is reduced, which not only provides installation space for the support mechanism, but also facilitates the rotation of the first drive member.

[0010] In some embodiments, the second body is slidably arranged on the first body along the direction of gravity.

[0011] In the above technical solution, the second body is adjustable and slidably arranged on the first body along the direction of gravity, so that the support mechanism can float in a small range in the direction of gravity, which facilitates loading and unloading of the laser cutting equipment.

[0012] In some embodiments, the second body has a first side facing away from the base in the direction of gravity; the support mechanism includes a clamping member, which is at least a pair of clamping members arranged at intervals on the first side along the first direction, each pair of clamping members has two clamping members, and at least one of each pair of clamping members can move along the first direction.

[0013] In the above technical solution, since at least one of each pair of clamping members can move along the first direction, on the one hand, when clamping the pipe, the distance between the clamping members can be adjusted in the first direction so that a pair of clamping members can clamp the pipe, so that when clamping metal pipes such as square pipes, I-beams and channel steels, the parts of the two clamping members protruding from the first side in the direction of gravity do not need to exceed the cross-sectional center of the pipe to firmly clamp the pipe, which means that the length of the abutment is reduced, and the strength and rigidity are increased, thereby reducing the deformation of the abutment during the clamping process and increasing the stability of the clamping; on the other hand, the two clamping members can clamp pipes of any size in the first direction, thereby increasing the scope of use of the device.

[0014] In some embodiments, the second body has a second side in the second direction, the second side is adjacent to the first side, and the first direction, the second direction, and the direction of gravity are perpendicular to each other; the support mechanism further includes a first gear, two racks, and a second drive member. The first gear is rotatably disposed on the second side; the two racks are along the direction of gravity, the first gear is located between the two racks, and the two racks are respectively engaged with the first gear; one of each pair of clamping members is connected to one of the two racks, and the other of each pair of clamping members is connected to the other of the two racks; the second drive member is configured to drive one of the two racks to move along the first direction.

[0015] In the above technical solution, the above structure enables the two clamping members to move away from or closer to each other at the same time, so that the clamping members can make the pipe have better centering when clamping the pipe.

[0016] In some embodiments, the second body has a third side in the second direction, and the first direction, the second direction and the direction of gravity are perpendicular to each other; the support mechanism includes a support member, which is adjustably arranged on the third side along the direction of gravity, and the support member has a fourth side facing away from the base along the direction of gravity, and the fourth side has a first surface and a second surface connected to each other, and an angle is formed between the first surface and the second surface.

[0017] In the above technical solution, an angle is formed between the first surface and the second surface so that the clamping mechanism can limit and fix the circular pipe, thereby increasing the scope of use of the device.

[0018] In some embodiments, the second body has a first side facing away from the base in the direction of gravity, and the support mechanism further includes a guide member, a cam, and a third driving member. The guide member is disposed on the third side and has a guide surface facing the support member in the first direction; the cam is rotatably disposed on the support member and abuts the guide surface; and the third driving member is configured to drive the guide member toward the support member, thereby causing the first surface and the second surface to protrude from the first side in the direction of gravity.

[0019] In the above technical solution, the above design ensures that the first surface and the second surface will not affect the pipe when clamping the non-circular pipe, thereby reducing the risk that the axis of the pipe will be at an angle to the first direction due to the setting of the support frame, making it inconvenient to clamp the chuck.

[0020] In some embodiments, the support member has a first positioning hole extending therethrough along the second direction, and a second positioning hole on the third side. When the first surface and the second surface protrude from the first side along the direction of gravity, the first positioning hole and the second positioning hole are coaxial. The support mechanism further includes a first positioning pin and a fourth driving member. The first positioning pin is inserted into the first positioning hole. The fourth driving member is provided on the support member and is configured to drive the first positioning pin into or away from the second positioning hole when the first positioning hole and the second positioning hole are coaxial.

[0021] In the above technical solution, the first positioning pin is inserted into the second positioning hole when the first positioning hole is coaxial with the second positioning hole to fix the support member and the second body, thereby reducing the risk of the support member falling downward during the chuck clamping process.

[0022] In some embodiments, the laser cutting support device further includes a second positioning pin and a fifth driving member. The swing arm mechanism has a third positioning hole, which is coaxial with the second positioning pin when the swing arm mechanism is in the first position. The fifth driving member is disposed on the base and is configured to drive the second positioning pin into or away from the third positioning hole when the swing arm mechanism is in the first position.

[0023] In the above technical solution, when the swing arm mechanism is in the first position, the second positioning pin is driven to be inserted into the third positioning hole to fix the base and the swing arm mechanism in the first position, thereby reducing the risk of the chuck failing to grasp the pipe due to the rotation of the swing arm mechanism in the first position.

[0024] In a second aspect, an embodiment of the present application provides a laser cutting device including the support device for laser cutting as mentioned in any of the above embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0040] Laser cutting equipment is a high-tech product that integrates CNC technology, laser cutting, and precision machinery. It is primarily used for cutting metal pipes such as round and square tubes, I-beams, and channels. Its cut surfaces are burr-free and dross-free, and it produces a variety of cutting patterns. Its professionalism, high efficiency, and cost-effectiveness make it the preferred equipment for the non-contact metal pipe processing industry.

[0041] However, the laser cutting support device of the existing laser cutting equipment avoids the movement of the chuck along the bed direction by moving vertically downward, thereby increasing the height of the bed, and further increasing the overall volume and occupied space of the equipment.

[0042] In order to solve the above technical problems, refer to Figures 1-10 The present invention provides a support device for laser cutting, which is used to place a pipe before the chuck of the laser cutting equipment grasps the pipe. The support device includes a base 1, a swing arm mechanism 2, and a support mechanism 3. The swing arm mechanism 2 is rotatably mounted on the base 1, with the axis of rotation of the swing arm mechanism 2 parallel to the direction of gravity Z. The support mechanism 3 is used to place the pipe and is mounted on the swing arm mechanism 2. The swing arm mechanism 2 has a first position and a second position. The support mechanism 3 is configured such that: in the first position, its extension direction is perpendicular to the movement direction P of the chuck; in the second position, its extension direction is parallel to the movement direction P of the chuck.

[0043] The base 1 can be a combination of one or more of a bracket and a mounting base. For example, the base 1 can include a mounting base 11 and a column 12, wherein one end of the column 12 is mounted on the mounting base 11 and the other end extends along the gravity direction Z. The swing arm mechanism 2 is rotatably mounted on the mounting base 11 at one end in the gravity direction Z, and rotatably mounted on the other end of the column 12 away from the mounting base 11 at the other end.

[0044] The swing arm mechanism 2 is a structure for driving the support mechanism 3 to rotate. Figure 2 In the figure, the state of the swing arm mechanism 2 when it is in the second position is represented by a dotted line.

[0045] The supporting mechanism 3 is a clamp structure for clamping pipes. For example, the pipes may be metal pipes such as round pipes, square pipes, I-beams, and channel steels.

[0046] Specifically, when it is necessary to load the laser cutting equipment through the laser cutting support device, the swing arm mechanism is adjusted to the first position so that the extension direction of the support mechanism 3 is perpendicular to the movement direction P of the chuck, thereby making the extension direction of the pipe parallel to the movement direction P of the chuck, so that the chuck can grasp one end of the pipe; after the chuck of the laser cutting equipment grasps the pipe, the swing arm mechanism is adjusted to the second position so that the swing arm mechanism and the swing arm mechanism are located on one side of the chuck and parallel to the movement direction P of the chuck, so as not to affect the movement of the chuck.

[0047] In the above technical solution, by rotatably setting the swing arm mechanism 2 on the base 1, relative to the support device that moves the support mechanism 3 along the gravity direction Z so that the support mechanism 3 avoids the movement path of the chuck, the laser cutting support device can avoid the movement of the chuck along the bed direction by rotating the swing arm mechanism 2, thereby effectively reducing the size of the support mechanism 3 in the gravity direction Z, reducing the overall volume and occupied space of the equipment. Moreover, on the projection surface perpendicular to the movement direction P of the chuck, the positive projection of the swing arm mechanism 2 in the second position can still partially or completely overlap with the positive projection of the base 1, so that the swing arm mechanism 2 in the second position can still share part of the space with the base 1, thereby improving the structural compactness of the device and reducing the space waste of the device; at the same time, because the swing arm mechanism is in the second position, it can drive the support mechanism 3 to be located on the relative outside of the laser cutting equipment, which can facilitate the workers to load the pipe when in the second position.

[0048] According to some embodiments of the present application, the swing arm mechanism 2 includes a mounting frame 21 and a first driving member 22. The mounting frame 21 includes a first body 211 extending along the gravity direction Z and a second body 212 extending along the first direction X. The first body 211 is rotatably mounted on the base 1, and the support mechanism 3 is mounted on the second body 212. The first direction X is perpendicular to the gravity direction Z. The first driving member 22 is configured to drive the first body 211 to rotate.

[0049] The first body 211 and the second body 212 are two main parts of the mounting frame 21 . It can be understood that the first body 211 and the second body 212 can be integrally formed or connected by welding or other methods.

[0050] In some embodiments, the first body 211 and the second body 212 may be made of metal material to reduce the risk of deformation of the mounting frame 21 when bearing the weight of the pipe and the support mechanism 3 .

[0051] It can be understood that the first body 211 can be rotatably connected to the base 1 through a bearing.

[0052] The first driving member 22 can be a driving element such as a drive motor or a rotary cylinder. For example, when the first driving member 22 is a drive motor, a second gear is provided at the output end of the first driving member 22, and a third gear is provided at one end of the first body 211 to mesh with the second gear. Through gear transmission, the first driving member 22 can drive the first body 211 to rotate.

[0053] In the present technical solution, by providing the mounting frame 21 with a first body 211 extending along the gravity direction Z and a second body 212 extending along the first direction X, the volume of the space occupied by the mounting frame 21 as a whole in the gravity direction Z and the first direction X is reduced, and the mass of the mounting frame 21 is reduced, which not only provides installation space for the support mechanism 3, but also facilitates the rotation of the first drive member 22.

[0054] According to some embodiments of the present application, the second body 212 is slidably arranged on the first body 211 along the gravity direction Z.

[0055] In some embodiments, a sixth driving member is installed on the mounting frame 21 , and the sixth driving member is used to drive the second body 212 to move along the gravity direction Z.

[0056] In this technical solution, the second body 212 is adjustable and slidably arranged on the first body 211 along the gravity direction Z, so that the support mechanism 3 can float in a small range in the gravity direction Z, which facilitates loading and unloading of the laser cutting equipment.

[0057] According to some embodiments of the present application, the second body 212 has a first side 212A facing away from the base 1 in the direction of gravity Z; the support mechanism 3 includes a clamping member 31, which is at least a pair of clamping members 31 arranged at intervals on the first side 212A along the first direction X, each pair of clamping members 31 is two, and at least one of each pair of clamping members 31 can move along the first direction X.

[0058] The clamping member 31 is a component used to clamp the pipe. For example, the clamping member 31 can be a clamp component such as an abutment block or a pressure arm.

[0059] In some embodiments, a roller is provided on the clamping member 31 , and the circumference of the roller abuts against the pipe.

[0060] Since the swing arm mechanism 2 drives the support mechanism 3 and the pipe to rotate, there is a risk that the pipe will move relative to the support mechanism 3 along the first direction X during feeding. By adjusting the distance between the clamping members 31 in the first direction X so that a pair of clamping members 31 clamp the pipe, the risk of the pipe moving along the first direction X can be reduced.

[0061] In the present technical solution, since at least one of each pair of clamping members 31 can move along the first direction X, on the one hand, when clamping the pipe, the distance between the clamping members 31 can be adjusted in the first direction X so that a pair of clamping members 31 can clamp the pipe, so that when clamping metal pipes such as square pipes, I-beams and channel steels, the parts of the two clamping members protruding from the first side 212A in the gravity direction Z do not need to exceed the cross-sectional center of the pipe to firmly clamp the pipe, which means that the length of the abutment is reduced, and the strength and rigidity are increased, thereby reducing the deformation of the abutment during the clamping process and increasing the stability of the clamping; on the other hand, the two clamping members can clamp pipes of any size in the first direction X, thereby increasing the scope of use of the device.

[0062] In some embodiments, the second body 212 has a second side 212B in the second direction Y, the second side 212B being adjacent to the first side 212A. The first direction X, the second direction Y, and the direction of gravity Z are perpendicular to each other. The support mechanism 3 further includes a first gear 32, two racks 33, and a second drive member 34. The first gear 32 is rotatably disposed on the second side 212B. The two racks 33 are along the direction of gravity Z, with the first gear 32 positioned between the two racks 33. The two racks 33 are respectively engaged with the first gear 32. One of each pair of clamping members 31 is connected to one of the two racks 33, and the other of each pair of clamping members 31 is connected to the other of the two racks 33. The second drive member 34 is configured to drive one of the two racks 33 to move along the first direction X.

[0063] The second driving component 34 can be a driving component such as a cylinder, a hydraulic cylinder, a linear module, and an electric telescopic rod.

[0064] It can be understood that the clamping member is slidably disposed on the first side 212A or the second side 212B via a slide rail.

[0065] Specifically, the second driving member 34 drives any rack 33 to move along the first direction X, so that the rack 33 drives the first gear 32 to rotate and thereby drives the other rack 33 to move, thereby causing the two clamping members to move away from or closer to each other at the same time.

[0066] In the present technical solution, the above structure enables the two clamping members to move away from or closer to each other at the same time, so that the clamping members can make the pipe have better centering when clamping the pipe.

[0067] According to some embodiments of the present application, the second body 212 has a third side 212C in the second direction Y, and the first direction X, the second direction Y and the gravity direction Z are perpendicular to each other; the support mechanism 3 includes a support member 35, which is adjustably arranged on the third side 212C along the gravity direction Z, and the support member 35 has a fourth side away from the base 1 along the gravity direction Z, and the fourth side has a first surface 351 and a second surface 352 that are interconnected, and there is an angle between the first surface 351 and the second surface 352.

[0068] In some embodiments, rollers are provided on the first surface 351 and the second surface 352 , and the circumference of the rollers abuts against the tube.

[0069] In the present technical solution, an angle is formed between the first surface 351 and the second surface 352 so that the clamping mechanism can limit and fix the circular pipe, thereby increasing the scope of use of the device.

[0070] According to some embodiments of the present application, the second body 212 has a first side 212A facing away from the base 1 in the direction of gravity Z. The support mechanism 3 further includes a guide member 36, a cam 37, and a third driving member 38. The guide member 36 is disposed on the third side 212C and has a guide surface facing the support member 35 in the first direction X. The cam 37 is rotatably disposed on the support member 35 and abuts the guide surface. The third driving member 38 is configured to drive the guide member 36 toward the support member 35, thereby driving the first surface 351 and the second surface 352 to protrude from the first side 212A along the direction of gravity Z.

[0071] The guide member 36 may be a wedge-shaped block. Exemplarily, the guide member 36 is slidably disposed on the third side 212C along the first direction X via a slide rail.

[0072] In some embodiments, the support member 35 has a protrusion on a side facing the wedge block, and the cam 37 is rotatably disposed on the protrusion and abuts against the guide surface of the guide member 36.

[0073] The third driving component 38 can be a driving component such as a cylinder, a hydraulic cylinder, a linear module, and an electric telescopic rod.

[0074] In this technical solution, the above design ensures that the first surface 351 and the second surface 352 will not affect the pipe when clamping the non-circular pipe, thereby reducing the risk of the axis of the pipe being at an angle to the first direction X due to the setting of the support frame, making it inconvenient to clamp the pipe with the chuck.

[0075] According to some embodiments of the present application, the support member 35 has a first positioning hole 353 extending therethrough along the second direction Y, and a second positioning hole 2121 on the third side 212C. When the first surface 351 and the second surface 352 protrude from the first side 212A along the gravity direction Z, the first positioning hole 353 and the second positioning hole 2121 are coaxial. The support mechanism 3 further includes a first positioning pin 391 and a fourth driving member 39. The first positioning pin 391 is inserted into the first positioning hole 353. The fourth driving member 39 is disposed on the support member 35 and is configured to drive the first positioning pin 391 into or away from the second positioning hole 2121 when the first positioning hole 353 and the second positioning hole 2121 are coaxial.

[0076] The fourth driving component 39 can be a driving component such as a cylinder, a hydraulic cylinder, a linear module, and an electric telescopic rod.

[0077] In this technical solution, the first positioning pin 391 is inserted into the second positioning hole 2121 when the first positioning hole is coaxial with the second positioning hole 2121 to fix the support member 35 and the second body 212 to reduce the risk of the support member 35 falling downward during the chuck clamping process.

[0078] According to some embodiments of the present application, the support device for laser cutting further includes a second positioning pin 41 and a fifth driving member 4. The swing arm mechanism 2 has a third positioning hole 2111. When the swing arm mechanism 2 is in the first position, the third positioning hole 2111 is coaxial with the second positioning pin 41. The fifth driving member 4 is disposed on the base 1 and is configured to drive the second positioning pin 41 to be inserted into or away from the third positioning hole 2111 when the swing arm mechanism 2 is in the first position.

[0079] The fifth driving member 4 can be a driving member such as a cylinder, a hydraulic cylinder, a linear module and an electric telescopic rod. For example, a mounting portion 13 for mounting the fifth driving member 4 is provided on the column 12, and a through hole is opened on the mounting portion 13 for two positioning pins 41 to pass through.

[0080] In this technical solution, when the swing arm mechanism 2 is in the first position, the second positioning pin 41 is driven to be inserted into the third positioning hole 2111 to fix the base 1 and the swing arm mechanism 2 in the first position, thereby reducing the risk of the chuck failing to grasp the pipe due to the rotation of the swing arm mechanism 2 in the first position.

[0081] An embodiment of the present application provides a laser cutting device including a support device for laser cutting as mentioned in any of the above embodiments.

[0082] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.
