Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a laser cutting machine. Background Art

[0002] Laser cutting replaces traditional mechanical knives with laser beams, and has the characteristics of high precision, fast cutting, smooth incision, and low processing cost. The mechanical part of the laser cutting head has no contact with the workpiece, and will not scratch the surface of the workpiece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat affected zone is small, the workpiece deformation is small, the cutting seam is narrow, the incision has no mechanical stress, and there are no shear burrs; the processing accuracy is high, the repeatability is good, and the material surface is not damaged. At present, most of the small-format laser cutting machines on the market are fixed workbenches, which are affected by the frame when changing materials, which is very inconvenient. In order to facilitate the replacement of materials, a pull-out workbench is designed. When cutting materials, due to its mobility, there is a problem of scrapping the materials due to the movement of the workbench during cutting. Summary of the invention

[0003] In order to overcome the defects in the prior art, the present invention provides a laser cutting machine, whose worktable can reciprocate between a second position and a first position along a first direction, so that the worktable can be moved out of the cover, which is convenient for loading and adjusting the position of the material, and the worktable can be fixed in the second position or the first position.

[0004] To achieve the above object, the technical solution adopted by the present invention is: a laser cutting machine comprising

[0005] A frame, wherein the frame is provided with a movable lever;

[0006] A workbench, the workbench is arranged on the frame and can move relative to the frame, the workbench is provided with a lock, the lock can lock the movable gear lever, so as to fix the workbench in the first position;

[0007] A stopper, the stopper is arranged on the frame and is located on the moving path of the workbench;

[0008] A positioning member, wherein the positioning member is arranged on the frame, and the positioning member includes a base fixed to the frame, a limiting member rotatably connected to the base, and a first driving member connected to the limiting member. Under the drive of the first driving member, the limiting member can rotate around the base, thereby clamping the frame of the workbench between the limiting member and the stop member.

[0009] Through the above technical solution, when it is necessary to load materials or adjust the position of materials, the workbench is moved out of the frame to the first position, and the workbench is fixed by clamping the lock with the movable lever, which is convenient for the staff to operate. When it is necessary to cut the materials, the lock is released, the workbench moves to the second position, and the first driving member drives the limit member to rotate to the moving path of the workbench, limiting the workbench between the limit member and the stop member. This solution makes loading materials and adjusting the position of materials more convenient.

[0010] Furthermore, the movable lever is connected to the frame via a second driving member, and the second driving member can drive the movable lever to leave the lock buckle;

[0011] The workbench is provided with a connecting piece, and the lock is rotatably connected to the connecting piece. An extension portion is provided on the upper side of the lock, and the upper side of the connecting piece supports the extension portion to limit the rotation of the lock. The lock has a slot, and the lock can be rotated until the movable gear lever is inserted into the slot.

[0012] Through the above scheme, when the workbench moves to the first position to load materials or adjust the position of the material, the lock is rotated to make the movable gear rod engage in the lock to limit the movement of the workbench. After the material is ready, the second driving member drives the movable gear rod to leave the lock to make the workbench movable.

[0013] Furthermore, the first side of the lock is set as an inclined surface. When the workbench moves away from the frame, as the inclined surface contacts the movable gear rod, the lock rotates toward the side away from the movable gear rod until the slot of the lock moves to the movable gear rod, and the lock rotates toward the movable gear rod so that the movable gear rod is located in the slot.

[0014] Through the above solution, when the workbench moves from the second position to the first position, the movable lever can always be in the restricted position. When the workbench moves to the first position, the lock and the movable lever are automatically locked without adding another positioning device.

[0015] Furthermore, the workbench includes a plurality of tooth plates arranged along a first direction, and a universal ball disposed between the tooth plates, wherein the universal ball is connected to a rotating shaft, and the universal ball can rotate along the rotating shaft to a position higher than the upper edge of the tooth plate, or rotate to a position lower than the upper edge of the tooth plate.

[0016] Through the above solution, when it is necessary to load or adjust the position of the material, the rotating shaft drives the universal ball to rotate to a position higher than the upper edge of the tooth plate, and the material is supported by the universal ball, which is convenient for the staff to move the material and can prevent the tooth plate from scratching the material. After the material is positioned, the rotating shaft drives the universal ball to rotate to a position lower than the upper edge of the tooth plate, and the material is supported by the tooth plate to prevent the material from moving during cutting.

[0017] Furthermore, the inner side of the frame is provided with pulleys arranged along the first direction, the side of the workbench relative to the pulley is provided with a support plate, and the support plate is supported on the pulley. The pulley can rotate freely to realize the movement of the workbench relative to the frame.

[0018] Furthermore, a protective plate is provided on at least the upper side of the pulley, and the protective plate separates the pulley from the table top of the workbench to prevent smoke and dust generated during the cutting process from entering the pulley, thereby extending the service life of the pulley.

[0019] Furthermore, at least two stoppers are provided, the stoppers are arranged perpendicular to the first direction and spaced apart, and a buffer is provided on the side of the stopper facing the workbench. The stopper can cooperate with the positioning member to clamp the workbench, and can also be used to position the workbench at the second position. When the workbench moves to the second position, it needs to collide with the stopper, and the buffer is used to protect the workbench and avoid it from being damaged when it collides with the stopper.

[0020] Furthermore, a positioning plate is provided on the workbench, and the positioning plate is used to position the material to be processed. The positioning plate is connected to the workbench through a cylinder, and the cylinder can drive the positioning plate to rise to a position higher than the upper edge of the workbench, or to fall below the upper edge of the workbench. When it is necessary to position the material, the cylinder drives the positioning plate to rise, and at the same time, the above-mentioned rotating shaft drives the universal ball to rotate to a position higher than the upper edge of the tooth plate to support the material. The staff moves the material to a preset position, and the rotating shaft drives the universal ball to rotate to a position lower than the upper edge of the tooth plate, and at the same time, the cylinder drives the positioning plate to fall.

[0021] Furthermore, it also includes a cover shell, which can be opened and closed along a first side of a first direction, and the frame is arranged in the cover shell.

[0022] Furthermore, a handle is provided on the first side of the workbench.

[0023] By means of the above technical solution, the beneficial effects of the present invention are as follows:

[0024] 1. The present application is provided with a rotatable limiter and a stopper. When the material needs to be cut, the limiter rotates to clamp the workbench between the limiter and the stopper to fix the workbench, thereby preventing the workbench from moving during cutting, thereby ensuring cutting accuracy and improving the yield rate;

[0025] 2. In the present application, the first side of the lock is set as an inclined surface. When the workbench moves toward the first position, the movable lever is pre-set at the limit position. The lock contacts the movable lever along with the workbench. During the process, due to the inclined surface design, the lock is forced to rotate upward until the slot of the bayonet reaches the limit position. The lock rotates downward due to its own gravity to lock the movable lever to fix the workbench. At this time, the workbench is in the first position. This design can directly position the workbench in the first position without the need for the staff to confirm whether the workbench has reached the first position, thereby improving production efficiency.

[0026] 3. In the present application, the workbench is connected to the frame via a pulley, that is, the workbench can move relative to the frame so that part of the workbench extends out of the frame, making it convenient for workers to load materials or adjust the position of materials.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that, in the description of the present invention, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0038] Example: Combination Figure 1-6 As shown, this embodiment discloses a laser cutting machine, including

[0039] The cover shell 1 can be opened and closed along a first side of a first direction, and a door panel 11 that can slide to both sides is provided at the opening and closing position.

[0040] The housing 1 is provided with a frame 2, and the four corners of the bottom of the frame 2 are provided with adjustable support seats 21, and the frame can be kept level by adjusting the height of each support seat 21. A track 12 is provided on the first side of the frame 2, and the door panel 11 is slidably connected to the track 12.

[0041] A pulley mounting plate 22 is detachably connected to the inner side of the frame 2. Two pulley mounting plates 22 are detachably connected to opposite sides of the frame. The pulley mounting plates 22 extend along a first direction. The first direction is the moving direction of the workbench 3. Pulleys 23 are arranged on the pulley mounting plates 22 at intervals.

[0042] A workbench 3 is provided on the two rows of pulleys 23, and the workbench 3 is detachably connected with support plates 31 on both sides of the pulley 23, and the workbench 3 is supported on the pulley 23 through the support plates 31. That is, the workbench 3 can reciprocate between the second position and the first position relative to the frame 2. The second position and the first position extend along the first direction. The second position is the position of the workbench 3 when the laser cutting machine cuts the material, and the first position is the position of the workbench 3 when loading or adjusting the position of the material.

[0043] Optionally, the pulley 23 can be replaced by any device such as a track, a roller, etc. that can drive the workbench 3 to move.

[0044] A first position-limiting member is provided on the first side of the frame 2, and the first position-limiting member includes a first cylinder 24 fixedly connected to the frame 2, and a movable lever 25 connected to the driving end of the first cylinder 24. When the first cylinder 24 is extended, the movable lever 25 is located at the limiting position, and when the first cylinder 24 is retracted, the movable lever 25 leaves the limiting position. It should be noted that the limiting position is the position of the movable lever 25 when the movable lever 25 is inserted into the lock buckle 33.

[0045] The workbench 3 is provided with a second limiter that cooperates with the first limiter, and the second limiter includes a connector 32 fixedly connected to the bottom of the workbench 3, and a lock 33 rotatably connected to the connector 32. In the present application, two connectors 32 are arranged in parallel, and the lock 33 is arranged between the two connectors 32. The upper side of the lock 33 is provided with an extension extending toward the two connectors 32, and the two connectors 32 support the extension, thereby limiting the rotation angle of the lock 33. It should be noted that the position on the workbench 3 relative to the lock 33 is hollowed out to avoid the rotation of the lock 33. When it is necessary to load materials or adjust the position of the material, the workbench 3 is moved to the first position, and the movable gear lever 25 is clamped by the lock 33 to fix the workbench 3, so as to facilitate the staff to load materials or adjust the position of the material.

[0046] Among them, the first side of the lock 33 is set as an inclined surface. During the movement of the workbench 3 toward the first position, the inclined surface of the lock 33 first contacts the movable lever 25, causing the lock 33 to rotate toward the upper side until the slot of the lock 33 moves to the movable lever 25, and the lock 33 rotates toward the movable lever 25 so that the movable lever 25 is located in the slot. Through the above scheme, when the workbench moves from the second position to the first position, the movable lever 25 can always be in the restricted position. When the workbench 3 moves to the first position, the lock 33 and the movable lever 25 are automatically locked. There is no need for the staff to confirm whether the workbench 3 has reached the first position, and there is no need to set an additional positioning device, thereby improving production efficiency. After loading or adjusting the position of the material, the first cylinder 24 drives the movable lever 25 to leave the restricted position so that the workbench 3 can be movable. It should be noted that the first cylinder 24 can be replaced by any device such as a lift that can drive the movable lever 25 to move, and the moving direction of the movable lever 25 can also be determined according to actual conditions.

[0047] A positioning member 4 is provided on the frame 2 near the second side, and the positioning member 4 includes a base 41 fixed to the frame 2, a limiting member 42 rotatably connected to the base 41, and a first driving member connected to the limiting member 42, and the limiting member 42 can rotate around the base 41 under the drive of the first driving member. In the present application, the first driving member is a second cylinder 43. A stopper is also provided on the frame 2. In the present application, the stopper includes two baffles 44 arranged perpendicular to the first direction and spaced apart, and the baffles 44 are located on the second side of the workbench 3. When the workbench 3 moves to the second position, the second side of the workbench 3 contacts the baffles 44. At this time, the second cylinder 43 drives the limiting member 42 to rotate to the moving path of the workbench 3, and clamps the workbench 3 between the limiting member 42 and the baffles 44, so that the workbench 3 is fixed, and the workbench is prevented from moving when cutting the material, thereby ensuring the cutting accuracy and improving the yield rate.

[0048] A buffer is provided on the side of the baffle 44 facing the workbench 3. The baffle 44 can cooperate with the positioning member 4 to clamp the workbench, and can also be used to position the workbench 3 at the second position. When the workbench 3 moves to the second position, it needs to collide with the baffle 44, and the buffer is used to protect the workbench 3 from being damaged when it collides with the baffle 44.

[0049] The first side and the second side are two opposite sides in the moving direction of the workbench 3. A handle 34 is provided on the first side of the workbench 3, and a worker can hold the handle 34 to adjust the position of the workbench 3 relative to the frame 2.

[0050] A protective plate 26 is provided on the upper side of the pulley mounting plate 22 , and the protective plate 26 separates the pulley 23 from the work surface to prevent smoke generated during cutting from entering the pulley 23 , thereby protecting the pulley 23 and extending the service life of the pulley 23 .

[0051] Through the above technical solution, when it is necessary to load materials or adjust the position of the material, the workbench 3 is moved out of the frame 2 to the first position, and the lock 33 is clamped by the movable lever 25 to fix the workbench 3, which is convenient for the staff to operate. When it is necessary to cut the material, the lock 33 is released, the workbench 3 moves to the second position, and the second cylinder 43 drives the limiter 42 to rotate to the moving path of the workbench 3, and the workbench 3 is limited between the limiter 42 and the baffle 44. This solution makes it more convenient to load materials and adjust the position of the material.

[0052] The workbench 3 includes a plurality of tooth plates 35 arranged along a first direction, and a universal ball 36 disposed between the tooth plates 35 . The universal ball 36 is connected to a rotating shaft 37 . The universal ball 36 can rotate along the rotating shaft 37 to a position higher than the upper edge of the tooth plates 35 , or to a position lower than the upper edge of the tooth plates 35 .

[0053] Through the above solution, when it is necessary to load or adjust the position of the material, the rotating shaft 37 drives the universal ball 36 to rotate to a position higher than the upper edge of the tooth plate 35, and the universal ball 36 is used to support the material, which is convenient for the staff to move the material and can prevent the tooth plate 35 from scratching the material. After the material is positioned, the rotating shaft 37 drives the universal ball 36 to rotate to a position lower than the upper edge of the tooth plate 35, and the tooth plate 35 is used to support the material to prevent the material from moving during cutting.

[0054] The workbench 3 is also provided with a positioning plate, which is used to position the material to be processed. The positioning plate is connected to the workbench 3 through a cylinder, and the cylinder can drive the positioning plate to rise above the upper edge of the workbench 3, or to fall below the upper edge of the workbench 3. When it is necessary to position the material, the cylinder drives the positioning plate to rise, and at the same time, the rotating shaft 37 drives the universal ball 36 to rotate to a position above the upper edge of the tooth plate 35 to support the material. The staff moves the material to a preset position, and the rotating shaft 37 drives the universal ball 36 to rotate to a position below the upper edge of the tooth plate 35, and at the same time, the cylinder drives the positioning plate to fall.

[0055] It should be noted that the present application also includes a crossbeam 5 arranged on the frame 2, a Z-axis moving component 6 connected to the crossbeam 5, a welding head connected to the Z-axis moving component, and an operating table 7 arranged outside the cover 1.

[0056] In another feasible embodiment, the pulley 23 or the workbench 3 is connected to a driving device, and the driving device can drive the pulley 23 or the workbench 3 to move, thereby realizing the automation of the movement of the workbench 3.
