Description

Technical Field

[0001] The invention relates to the field of laser cutting machines, in particular to a follower support mechanism, a laser tube cutting machine and a working method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Laser cutting machines have the advantages of energy saving and high cutting precision. Laser cutting machines can cut rotating objects to be processed, but during the laser cutting process, some objects to be processed are too long. The objects to be processed will droop downward under the action of their own weight, which not only affects the processing accuracy, but also cannot guarantee the centering problem. Therefore, a device is needed to lift the drooping object to be processed and rotate with the object to be processed, that is, to lift and lower the material according to the shape of the object to be processed.

[0004] The inventors found that some laser cutting machines do not have a suitable support structure, which greatly reduces the accuracy of the laser cutting machine. In addition, most of the mainstream follow-up support mechanisms on the market currently use multiple groups of cylinders to lift the support, the front cylinder descends, and the rear cylinder rises. The material unloading method has a complex structure, many action and detection signals, and a large overall volume, which limits the use of the entire mechanism.

[0005] Moreover, the general support device can only be used for round tube cutting. During the rotation of special-shaped tubes such as rectangular tubes and angle steels, the diameters are different, and the support mechanism suitable for round tube cutting cannot be used. Summary of the invention

[0006] In view of the deficiencies in the prior art, an object of the present invention is to provide a follower support mechanism that can be raised and lowered following the rotation of an object to be processed.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0008] A follower support mechanism includes a fixing part, which is installed on a bed and connected to a lifting part. The lifting part can be lifted or lowered relative to the fixing part. One side of the lifting part is movably connected to a follower support part. A flipping component is also provided between the lifting part and the follower support part. After the flipping component drives the follower support part to flip at a set angle, the follower support part can support a processing object. During the rotation of the processing object, the lifting part is lifted or lowered relative to the fixing part to drive the follower support part to be lifted or lowered along with the rotation of the processing object.

[0009] In a follower supporting mechanism as described above, when the follower support is retracted relative to the lifting member, the angle between the follower support and the lifting member is less than or equal to 15°, and after the flip assembly pushes the follower support out, the follower support can be in a horizontal position, effectively preventing the object to be processed from sagging under the action of its own weight.

[0010] A follower support mechanism as described above, the flip assembly includes a connecting rod, one end of the connecting rod is hingedly connected to the follower support, the other end of the connecting rod is movably connected to the hinge seat, the hinge seat cooperates with the hinge guide pair, the hinge seat is connected to the linear drive member to push the hinge seat to move along the hinge guide pair, and when the follower support is in a horizontal state under the drive of the linear drive member, the connecting rod is also in a horizontal state.

[0011] A follower support mechanism as described above, wherein a triangular support frame is provided on the side of the follower support member facing the lifting member, and one end of the connecting rod is hingedly connected to the triangular support frame;

[0012] The hinge guide pair is a linear guide, which is arranged along the height direction of the lifting member. The linear drive member is fixed to the lifting member, and the linear drive member is located on one side of the hinge guide pair.

[0013] In the above-mentioned follower supporting mechanism, a lifting component is arranged on a side of the fixing member facing the lifting member.

[0014] In a follower support mechanism as described above, the lifting assembly is a screw nut assembly, the screw can be rotatably fixed to the fixed part, the screw nut at the screw is installed on the lifting part, a servo motor is arranged on the side of the fixed part away from the lifting part, and the servo motor is connected to the screw through a transmission component.

[0015] In the above-mentioned follower supporting mechanism, the lifting member is a lifting plate, the fixing member is a fixing plate, and the fixing plate and the lifting plate are arranged parallel to each other.

[0016] In the above-mentioned follow-up supporting mechanism, the flipping assembly and the lifting assembly are respectively connected to the control assembly separately, and the control assembly controls the actions of the flipping assembly and the lifting assembly.

[0017] In the second aspect, the present invention provides a laser tube cutting machine, which adopts the above-mentioned follow-up supporting mechanism, and the control component is the controller of the laser tube cutting machine. The controller is connected to the rotating mechanism, and the rotating mechanism is used to drive the rotation of the object to be processed. The controller controls the lifting speed of the lifting component according to the rotation speed of the rotating mechanism and the size of the longitudinal cross-section of the object to be processed.

[0018] In a third aspect, the present invention provides a working method of a laser tube cutting machine, comprising the following contents:

[0019] A follow-up material support mechanism is arranged on one side of the laser tube cutting machine bed, and a fixing part is fixedly connected to the laser tube cutting machine bed;

[0020] The flip assembly pushes out the follower support;

[0021] Placing the object to be processed on the surface of the follower support member of the follower support mechanism, and the follower support member supports the object to be processed;

[0022] The laser tube cutting machine cuts the object to be processed. During the cutting process, driven by the lifting component, the lifting part rises and falls relative to the fixed part to drive the follower support part to rise and fall along with the rotation of the object to be processed;

[0023] After the work is finished, the flip assembly is retracted to retract the follower support.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1) In the present invention, the follower supporting mechanism has a fixed part fixed to the bed, and the lifting part can be raised and lowered relative to the fixed part. A flipping assembly is arranged at the lifting part, and the flipping assembly can drive the follower supporting part to flip to a set angle so that it can support the object to be processed. In this way, during the rotation of the object to be processed, the lifting part drives the follower supporting part to rise and fall with the rotation of the object to be processed, thereby realizing the follow-up support of the object to be processed, avoiding the occurrence of excessive cutting accuracy, and being beneficial to ensuring the centering of the object to be processed and realizing precision processing. It is not only suitable for circular objects to be processed, but also suitable for objects to be processed of other shapes.

[0026] 2) The follower support mechanism of the present invention has a simple and reasonable structure, which is conducive to controlling manufacturing costs. It does not have too many cylinders and the overall occupied area is small. Moreover, under the setting of the flip assembly, the follower support can be retracted to save space and facilitate the staff to load materials. After loading, the flip assembly is operated to allow the follower support to support the object to be processed.

[0027] 3) The structure of the flipping assembly in the present invention is reasonably arranged. The flipping assembly cooperates with the linear drive member, the connecting rod and the hinge guide pair. When the linear drive member drives the hinge seat to move along the hinge guide pair, the connecting rod flips the follower support member upward or downward to a set angle. When the follower support member is in a horizontal position, the connecting rod is also in a horizontal position, which is in the "dead point" position of the planar mechanism and cannot sag by gravity. The follower support member can only be flipped by the pull of the linear drive member, thereby ensuring stable support for the object to be processed.

[0028] 4) The laser tube cutting machine of the present invention adopts a follow-up supporting mechanism. The controller can control the lifting speed of the lifting assembly according to the rotation speed of the rotating mechanism and the size of the longitudinal section of the object to be processed, ensuring that the follow-up support can be accurately lifted and lowered following the rotation of the tube. It is not only suitable for the processing of round tubes, but also for the processing of special-shaped tubes. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof;

[0038] As introduced in the background technology, the follower support mechanism in the prior art has the problem of complex structure and is not suitable for special-shaped materials. In order to solve the above technical problems, the present invention proposes a follower support mechanism.

[0039] Embodiment 1

[0040] In a typical embodiment of the present invention, reference is made to Figure 1 , Figure 2 and Figure 3 As shown, a follower support mechanism includes a fixing member 8, which is installed on a bed. The fixing member 8 is connected to a lifting member 10, and the lifting member 10 can be lifted and lowered relative to the fixing member 8. One side of the lifting member 10 is movably connected to a follower support member 1. A flipping component is also provided between the lifting member 10 and the follower support member 1. After the flipping component drives the follower support member to flip at a set angle, the follower support member can support the object to be processed. During the rotation of the object to be processed, the lifting member 10 is lifted and lowered relative to the fixing member 8 to drive the follower support member 1 to be lifted and lowered along with the rotation of the object to be processed.

[0041] The object to be processed may be a pipe or other materials.

[0042] In this embodiment, the lifting member 10 is a lifting plate, the fixing member 8 is a fixed plate, and the follower support member is a follower support plate. The fixed plate and the lifting plate are arranged parallel to each other, and the fixed plate and the lifting plate are arranged vertically. The sizes of the lifting plate and the fixed plate can be the same or similar, and the size of the follower support plate is compatible with the size of the lifting member 10 and the fixing member 8. Of course, in other examples, the lifting member 10 and the fixing member 8 can also be components of other shapes.

[0043] It is easy to understand that a lifting component is provided on a side of the fixing member 8 facing the lifting member 10 .

[0044] In this embodiment, the lifting assembly is specifically a screw nut assembly 4, which includes a screw, which can be rotatably fixed to a fixing member 8. Both ends of the screw are connected to the fixing member 8 through bearing seats. Slide rails 9 are arranged on both sides of the screw. The lifting member 10 is provided with sliders to cooperate with the slide rails 9. The linear movement of the screw nut is ensured by the slide rails 9. The screw nut at the screw is installed on the lifting member 10, and the screw nut is connected to the lifting member 10 through a screw nut seat. A servo motor 7 is arranged on the side of the fixing member 8 away from the lifting member. The servo motor 7 is connected to the screw through a transmission component, and the screw nut is connected to the lifting member 10 through a screw nut seat. The transmission component is a synchronous belt transmission component. A synchronous pulley 5 is installed at the end of the screw. To avoid interference problems, the synchronous pulley 5 is arranged beyond the bottom end of the lifting member 10. A synchronous pulley is also installed at the shaft end of the servo motor 7. A synchronous belt is connected between the two synchronous pulleys. The rotation of the servo motor 7 drives the screw to rotate through the synchronous pulley, and the screw nut drives the lifting member 10 to slide up and down relative to the fixing member 8.

[0045] Among them, a motor mounting seat 6 is set at the bottom of the fixing member 8 away from the lifting member 10. The motor mounting seat 6 is specifically L-shaped, and one side of the motor mounting seat is fixed to the side of the fixing member 8 away from the lifting member 10. The servo motor 7 is supported by the motor mounting seat 6.

[0046] It should be noted that when the follower support 1 is retracted relative to the lifting member 10, the angle between the follower support 1 and the lifting member 10 is less than or equal to 15°. In this embodiment, when the flip assembly is retracted, the follower support 1 and the lifting member 10 can reach a state of being parallel to each other. After the flip assembly pushes the follower support 1 out, the follower support 1 can be in a horizontal position, which effectively prevents the object to be processed from sagging under the action of its own weight, thereby ensuring the processing accuracy and the centering problem of the object to be processed.

[0047] It can be understood that an upper support 13 is provided on the upper side of the lifting member 11 facing the follower support member 1, and the follower support member 11 is hingedly connected to the upper support 13 via a pin shaft;

[0048] It should be noted that the flip assembly includes a connecting rod 2, the length of which is smaller than the length of the follower support 1, one end of the connecting rod 2 is hingedly connected to the follower support 1, and the other end of the connecting rod 2 is hingedly connected to the hinge seat 3, the hinge seat 3 cooperates with the hinge guide pair 12 to make the hinge seat movable relative to the hinge guide pair 12, the hinge seat 3 and the hinge guide pair 13 adopt existing linear guides, wherein a convex portion is provided on one side of the hinge seat 3 for hinge connection with the connecting rod 2, the hinge seat 3 is connected to the linear drive member 11 to push the hinge seat to move along the hinge guide pair 12, and when the follower support 1 is in a horizontal state under the drive of the linear drive member 11, the connecting rod 2 is also in a horizontal state.

[0049] Specifically, the linear drive member 11 is fixed to the surface of the lifting member 11, and the linear drive member 11 is an existing rodless cylinder or a rodless electric cylinder. The setting direction of the linear drive member 11 is parallel to the hinge guide pair 12, and the telescopic end of the linear drive member 11 is connected to the side of the hinge seat 3. In this embodiment, a connecting block is set at the telescopic end of the linear drive member 11, and the connecting block is snap-connected or bolted to the side of the hinge seat 3, or connected in other ways. When snap-connected, the connecting block and the hinge seat 3 are respectively provided with hooks, and the snap-connection is achieved through the hooks.

[0050] A triangular support frame 14 is provided on one side of the follower support member 1 facing the lifting member 10. The length of the triangular support frame 14 is smaller than the length of the follower support member 1. One end of the connecting rod 2 is hingedly connected to an angle of the triangular support frame 14. When the flip assembly is retracted, the hinge point between the connecting rod and the follower support member 1 is higher than the hinge point between the connecting rod and the hinge seat 3.

[0051] Specifically, the hinge guide pair 12 is arranged along the height direction of the lifting member 10, the linear drive member 11 is fixed to the surface of the lifting member, the linear drive member 11 is located on one side of the hinge guide pair 12, and the linear drive member 11 and the hinge guide pair 12 are arranged at a distance. The linear drive member 11 can be arranged at the center position along the length direction of the lifting member 11.

[0052] It is easy to understand that the flip assembly and the lifting assembly are separately connected to the control assembly, and the control assembly controls the actions of the flip assembly and the lifting assembly.

[0053] The follow-up supporting mechanism provided in the present embodiment has a fixing part 8 fixed to the bed, and a lifting part 10 which can be lifted and lowered relative to the fixing part. A flipping assembly is arranged at the lifting part 10, and the flipping assembly can drive the follow-up supporting part to flip to a set angle so as to support the object to be processed. In this way, during the rotation of the object to be processed, the lifting part 10 drives the follow-up supporting part to be lifted and lowered as the object to be processed rotates, thereby realizing follow-up support for the object to be processed and avoiding causing a deviation in cutting accuracy, which is beneficial to ensuring the centering of the object to be processed and realizing precision processing. It is not only suitable for circular objects to be processed, but also for objects to be processed of other shapes.

[0054] Embodiment 2

[0055] The present embodiment provides a laser tube cutting machine, which adopts a follower supporting mechanism described in the first embodiment. The control component is the controller of the laser tube cutting machine. The controller is connected to the rotating mechanism. The rotating mechanism is used to drive the rotation of the object to be processed. The rotating mechanism is a prior art and will not be described in detail. The controller is programmed according to the rotation speed of the rotating mechanism and the size of the longitudinal section of the object to be processed, so that the controller controls the lifting speed of the lifting component according to the rotation speed of the rotating mechanism and the size of the longitudinal section of the object to be processed, so that the lifting speed of the lifting component is matched with the rotation speed and the cross-sectional size of the object to be processed, so as to meet the requirements that when special-shaped tubes such as rectangular tubes and angle steels are rotated, the follower support member 1 can ensure stable support for the object to be processed while lifting and lowering.

[0058] A follow-up support mechanism is arranged on one side of the laser tube cutting machine bed, and a fixing member 8 is fixedly connected to the laser tube cutting machine bed;

[0059] The flip assembly pushes out the follower support 1, and when the lead screw nut assembly 4 drives the lifting member 10 to rise to the set position, the linear drive member 11 extends to push the hinge seat 3 to slide upward on the hinge guide rail pair 12, and the hinge seat 3 pushes the follower support 1 to rotate to a horizontal position. At this time, the connecting rod 2 is also in a horizontal position, which is at the "dead point" position of the plane mechanism and cannot sag by gravity;

[0060] The object to be processed is placed on the surface of the follower support member 1 of the follower support mechanism, and the object to be processed is supported by the follower support member 1;

[0061] The laser tube cutting machine cuts the object to be processed.
