Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting equipment, in particular to a material supporting device and a laser cutting machine applying the same. Background Art

[0002] A laser cutting machine uses a laser beam for cutting. Since the cutting depth of the laser beam cannot be accurately controlled, after the laser beam passes through the workpiece to complete the cutting of the workpiece, it will continue to cut a certain distance below the workpiece. Therefore, the material supporting table of the existing laser cutting machine often uses a serrated plate as the material supporting member.

[0003] As Figure 1 shown, the material supporting table of the laser cutting machine includes two strip plates oppositely arranged on both sides of the frame. On the upper sides of the two strip plates, a plurality of grooves are provided along the length direction of the strip plates. The serrated plate includes a mounting plate and a plurality of serrations provided on the upper side of the middle of the mounting plate. The upper sides of the serrations are used to support the workpiece. The lower parts at both ends of the mounting plate are clamped in the grooves of the two strip plates on both sides, and a pressing plate is respectively provided on the upper sides at both ends of the mounting plate. The pressing plate is connected to the strip plate by a plurality of bolts to press a plurality of serrated plates on the two strip plates. During the cutting process, the serrations of some serrated plates will inevitably be damaged by the laser beam, resulting in uneven height, reducing the flatness of the supporting surface and affecting the product quality. Therefore, it needs to be replaced frequently.

[0004] However, when replacing the damaged serrated plate, the worker needs to remove all the bolts on the pressing plate on the corresponding side on both sides of the frame respectively, then remove the pressing plate, and finally take out the damaged serrated plate. And after the replacement is completed, it is also necessary to put the pressing plate on the corresponding side back on both sides of the frame respectively and install the pressing plate with bolts to complete the replacement work. The operation process is cumbersome and the work efficiency is low. Summary of the Utility Model

[0005] To solve the technical problem that in the existing laser cutting machine when replacing the serrated plate, the operation process of disassembling and assembling the serrated plate is cumbersome, resulting in low work efficiency in the above-mentioned background art, the utility model provides a material supporting device and a laser cutting machine applying the same.

[0006] The technical solution of the utility model is as follows:

[0007] A material supporting device includes a frame and two strip plates oppositely arranged thereon. A plurality of serrated plates with both ends respectively inserted and connected to the upper sides of the two strip plates are arranged in parallel between the two strip plates. When it is applied to a laser cutting machine, a plurality of serrated plates can be used to support the plate to be cut.

[0008] The core technical concept of the present utility model lies in that on one side of the two plates of the material supporting device, fixing rods are provided along the length direction thereof. One end of the serrated plate abuts against one of the fixing rods, and the other fixing rod is pressed on the upper side of the other end of the serrated plate. The fixing rod pressed on the upper side of the serrated plate is a pressing rod, one end of which is hingedly connected to the strip plate, and the other end is provided with a connecting member. A stop hole is provided on the connecting member, and a locking rod capable of being inserted and matched with the stop hole is spirally provided on the strip plate.

[0009] When disassembling the serrated plate, the worker rotates the locking rod to move out of the stop hole on the side where the pressing rod is provided, then rotates the pressing rod to move away from the serrated plate, and then takes out the serrated plate to be replaced from the two plates; when installing the serrated plate, the worker inserts the serrated plate on the two plates on the side where the pressing rod is provided, and pushes the serrated plate towards the side where the limiting rod is provided to position one end of the serrated plate, then rotates the pressing rod to press on the upper side of the serrated plate, and then rotates the locking rod into the stop hole to complete the installation of the serrated plate; through the above structural design, the worker can complete the replacement of the serrated plate only on one side of the laser cutting machine, without the need to perform the disassembly and assembly of several screws and the taking and placing operations of two pressing plates on both sides of the laser cutting machine successively as in the traditional laser cutting machine. The material supporting device simplifies the operation process of disassembling and assembling the serrated plate and improves the work efficiency.

[0010] In a material supporting device as described above, the fixing rod that abuts against the serrated plate is a limiting rod, and the limiting rod is fixed to the frame, so that the limiting rod provides a stable support point for the serrated plate. When the worker installs or adjusts the serrated plate, as long as the serrated plate is correctly placed and in contact with the limiting rod, its stability can be ensured without complex adjustment or multiple corrections.

[0011] As an implementation manner, one end of the serrated plate that abuts against the limiting rod is provided with a pressing groove that opens outward and can be in abutting fit with the limiting rod, and the limiting rod is arranged on the upper side of the strip plate to provide a fixed support point. The serrated plate is in abutting connection with the limiting rod through the pressing groove, which can increase the contact area and improve the stability of the abutting connection between the serrated plate and the limiting rod.

[0012] Furthermore, a fixing groove adapted to the pressing rod is also provided on the upper side of the serrated plate. By providing the fixing groove on the serrated plate, when the pressing rod presses the serrated plate, a tight fit is formed between the fixing groove and the pressing rod, which helps to prevent the serrated plate from moving greatly during use, ensures that it stably supports the workpiece, and the fixing groove can also serve as a guiding and positioning structure for the pressing rod, making the process of installing and disassembling the serrated plate faster and more accurate.

[0013] For the convenience of operation, the connecting member is arranged on the inner side of the strip plate, and the locking rod is perpendicular to the strip plate. During use, when the worker works outside the laser cutting machine, it is easier to see and touch the locking rod without reaching into an inconvenient position.

[0014] Preferably, both the limiting rod and the pressing rod are cylindrical rods, which are simple to manufacture, and the design of the cylindrical rod helps to reduce stress concentration caused by sharp edges or acute angles, and can improve the overall durability and reliability of the device.

[0015] The specifications of several sawtooth plates are the same, and the thickness of the sawtooth plate is 2 mm - 4 mm. Preferably, the thickness of the sawtooth plate is 3 mm, so as to maintain sufficient rigidity and strength while also maintaining the lightness of the material. A thickness of 3 mm is sufficient to support the workpiece placed on it while reducing the operational difficulties caused by excessive weight.

[0016] The two plates have the same specifications and a thickness of 10 mm - 12 mm. Preferably, the thickness of the two plates is 12 mm. During the laser cutting process, the thicker strip plate helps to reduce vibration because it has a greater mass and can absorb more kinetic energy. A strip plate thickness of 12 mm ensures that the strip plate can maintain its shape and stability even under long-term operation and repeated loads, extending the service life of the equipment.

[0017] The present utility model also provides a laser cutting machine, including a material supporting device as described above.

[0018] The beneficial effects of a material supporting device of the present utility model and a laser cutting machine using the same are that by respectively arranging a limiting rod and a pressing rod at both ends of the sawtooth plate, workers can complete the disassembly and assembly of the sawtooth plate only on one side of the laser cutting machine, and the disassembly and assembly process is simple. Compared with the traditional structure, the operation process of disassembling and assembling the sawtooth plate is simplified, and the work efficiency is improved.

[0029] Combined with Figure 2 and Figure 3 , this embodiment provides a material supporting device, including a frame 1 and two strips oppositely arranged thereon, and a plurality of serrated plates 3 whose two ends are respectively inserted and connected to the upper sides of the two strips are arranged in parallel between the two strips. When it is applied to a laser cutting machine, a plurality of serrated plates 3 can be used to support the plate to be cut.

[0030] The core technical concept of the present utility model is that the two strips of this material supporting device are the first strip 2 and the second strip 9. Fixed rods are arranged on one side of the two strips along their length directions. One end of the serrated plate 3 abuts against one of the fixed rods, and the other fixed rod is pressed on the upper side of the other end of the serrated plate 3. The fixed rod pressed on the upper side of the serrated plate 3 is the pressing rod 6. One end of the pressing rod 6 is hinged to one end of the first strip 2 through a support 5, and the other end is provided with a connecting piece 7. A stop hole is arranged on the connecting piece 7, and a locking rod 8 that can be inserted and matched with the stop hole is spirally arranged on the other end of the first strip 2.

[0031] Combined with Figure 4 and Figure 6 , the connecting piece 7 is arranged inside the first strip 2, and the locking rod 8 is perpendicular to the first strip 2. During use, when a worker works outside the laser cutting machine, it is easier to see and touch the locking rod 8, and there is no need to reach into an inconvenient position.

[0032] The first strip 2 and the second strip 9 have the same specifications and a thickness of 10 mm - 12 mm. Preferably, the thickness of the two strips is 12 mm. During laser cutting, the thicker strips help to reduce vibration because their mass is larger and they can absorb more kinetic energy. The 12 - mm strip thickness ensures that even under long - term operation and repeated loads, the two strips can maintain their shape and stability, extending the service life of the equipment.

[0033] Combined with Figure 5, the fixing rod that abuts against the sawtooth plate 3 is the limiting rod 4, and the limiting rod 4 is fixed to the frame 1, so that the limiting rod 4 provides a stable support point for the sawtooth plate 3. When installing or adjusting the sawtooth plate 3, the worker only needs to ensure that the sawtooth plate 3 is correctly placed and in contact with the limiting rod 4 to ensure its stability, without complex adjustment or multiple corrections.

[0034] Preferably, both the limiting rod 4 and the pressing rod 6 are cylindrical rods, which are simple to manufacture, and the cylindrical rod design helps to reduce stress concentration caused by sharp edges or acute angles, which can improve the overall durability and reliability of the device.

[0035] Combined with Figure 7 , one end of the sawtooth plate 3 that abuts against the limiting rod 4 is provided with a tightening groove 31 that opens outward and can tightly cooperate with the limiting rod 4, and the limiting rod 4 is arranged on the upper side of the second strip 9 to provide a fixed support point. And the sawtooth plate 3 is in contact with the limiting rod 4 through the tightening groove 31, which can increase the contact area and improve the stability of the contact between the sawtooth plate 3 and the limiting rod 4.

[0036] On the upper side of the sawtooth plate 3, there is also a fixing groove 32 adapted to the pressing rod 6. By providing the fixing groove 32 on the sawtooth plate 3, when the pressing rod 6 presses the sawtooth plate 3, a tight fit is formed between the fixing groove 32 and the pressing rod 6, which helps to prevent the sawtooth plate 3 from moving greatly during use, ensuring that it stably supports the workpiece. And the fixing groove 32 can also be used as a guiding and positioning structure for the pressing rod 6, making the process of installing and disassembling the sawtooth plate 3 faster and more accurate.

[0037] On the lower side of the end of the sawtooth plate 3 where the tightening groove 31 is provided, there is also a clearance chamfer structure. The clearance chamfer is to prevent physical interference between the sawtooth plate 3 and the second strip 9 when removing or installing the sawtooth plate 3, so that the sawtooth plate 3 can quickly and smoothly slide into or out of the strip, without using too much force and without getting stuck or damaged.

[0038] The specifications of several sawtooth plates 3 are the same, and the thickness of the sawtooth plate 3 is 2 mm - 4 mm. Preferably, the thickness of the sawtooth plate 3 is 3 mm, so as to maintain sufficient rigidity and strength while also maintaining the lightness of the material. The 3 - mm thickness is sufficient to support the workpiece placed on it while reducing the operation difficulty caused by excessive weight.

[0039] The present utility model also provides a laser cutting machine, including a material supporting device as described above.

[0040] Combined with Figure 2 and Figure 3 , along the length direction of the frame 1, several groups of material supporting strip groups are arranged in parallel, and each group of material supporting strip groups includes the first strip 2 and the second strip 9 as described above.

[0041] When disassembling the sawtooth plate 3, the worker turns the locking rod 8 to move out of the stop hole on the side of the laser cutting machine where the pressing rod 6 is set, then rotates the pressing rod 6 to move away from the sawtooth plate 3, and then takes out the sawtooth plate 3 to be replaced from the two plates; when installing the sawtooth plate 3, the worker inserts the sawtooth plate 3 on the two plates on the side of the laser cutting machine where the pressing rod 6 is set, and pushes the sawtooth plate 3 towards the side where the limiting rod 4 is set to position one end of the sawtooth plate 3, then rotates the pressing rod 6 to press on the upper side of the sawtooth plate 3, and then turns the locking rod 8 into the stop hole to complete the installation of the sawtooth plate 3; through the above structural design, the worker can complete the replacement of the sawtooth plate 3 only on one side of the laser cutting machine, without the need to disassemble and install several screws and take and place two pressing plates on both sides of the laser cutting machine successively as in the traditional laser cutting machine. This supporting material device simplifies the operation process of disassembling and installing the sawtooth plate 3 and improves the work efficiency.
