Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and in particular, to a laser cutting device with parallel exchange. Background Art

[0002] In recent years, the application of laser cutting machines has developed rapidly in the domestic market. Especially in the field of sheet metal cutting and processing, it has been well applied. It has the advantages of high cutting accuracy, fast cutting speed, being able to adapt to various complex graphics, automatic typesetting, smooth cut, and low processing cost, and has well replaced equipment such as punching machines, flame cutting, and plasma cutting.

[0003] Now, in order to improve the laser cutting efficiency, many laser cutting machines are set as a double-layer platform structure with parallel exchange, which can exchange and perform laser cutting on multiple groups of cutting profiles. The structure of the exchange table of the laser cutting machine can greatly improve the processing efficiency, and there are also many structural designs for the laser cutting exchange platform. For example, the Chinese patent utility model patent CN219189036U discloses a parallel exchange table for a laser cutting machine, which relates to the technical field of laser cutting machines. The utility model includes two longitudinally arranged and parallel longitudinal square tubes, and a plurality of laterally arranged transverse square tubes are welded between the two longitudinal square tubes. A plurality of anchor feet are respectively welded on the lower side surfaces of the two longitudinal square tubes, upper guide rails are respectively welded on the upper side surfaces of the two longitudinal square tubes, a plurality of lower rib plates are respectively welded on the mutually facing side surfaces of the two longitudinal square tubes, and lower guide rails are welded above the lower rib plates. The lower guide rails are located below the upper guide rails and are parallel to the upper guide rails. The welding process of the utility model is relatively simple, convenient for production and manufacturing, and the stability and precision of the guide rails are high.

[0004] However, the above horizontal exchange type laser cutting machine still has the following disadvantages: the working platform structure of the high-power parallel exchange laser cutting machine is complex, resulting in a relatively large occupation of the overall bed width.

[0033] Technologies, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be regarded as part of the authorization specification.

[0034] Embodiment 1: As Figures 1 to 9As shown, it is only one embodiment of the present utility model, a laser cutting device with parallel exchange, including a machine tool part 2, a workbench 1 arranged on the machine tool part 2, and a motor part 3 for driving the displacement of the workbench 1. The machine tool part 2 includes a first wallboard 21, a second wallboard 22, and an intermediate board 23 for connecting the first wallboard 21 and the second wallboard 22. The workbench 1 includes a first side board 11 for connecting with the first wallboard 21, a second side board 12 for connecting with the second wallboard 22, and a connecting board 13 for connecting the first side board 11 and the second side board 12. The motor part 3 includes a motor main body 31 arranged on the intermediate board 23, a driving wheel 32 connected to the motor main body 31, and a driving shaft rod 33 connected to the driving wheel 32. A first driving wheel 211 for connecting with the driving shaft rod 33 and a first chain 212 connected to the first driving wheel 211 are arranged on the first wallboard 21. A second driving wheel 221 for connecting with the driving shaft rod 33 and a second chain 222 connected to the second driving wheel 221 are arranged on the second wallboard 22.

[0035] In the present utility model, the machine tool part 2 is the machine tool main body of the entire laser cutting machine. A workbench and a cutting head are arranged on the machine tool. Laser is emitted at the cutting head to cut the material on the workbench. And there are two workbenches, and the two work platforms can be displaced. After the material on one work platform is cut, this work platform is removed, and the other work platform is displaced under the cutting head. At this time, the cutting head cuts the material on this work platform located under the cutting head, and the motor part 3 is the driving part for driving the displacement of the work platform.

[0036] In the present utility model, the machine tool part 2 includes a first wallboard 21, a second wallboard 22, and an intermediate board 23 for connecting the first wallboard 21 and the second wallboard 22. It can be understood that the machine tool part 2 includes the first wallboard 21 and the second wallboard 22 on the left and right sides, and then the intermediate board 23 is connected and arranged between the first wallboard 21 and the second wallboard 22 to connect and fix the first wallboard 21 and the second wallboard 22. There are multiple intermediate boards 23, so that the entire machine tool part 2 forms a semi-hollow structure with high structural strength. And the intermediate board 23 is arranged at the ends of the first wallboard 21 and the second wallboard 22. It should be noted that actually, the intermediate board 23 where the motor part 1 is arranged is arranged at the ends of the first wallboard 21 and the second wallboard 22, or in other words, the motor part 3 is arranged on the intermediate board 23 at the end of the machine tool part 2.

[0037] First, it is the structure of the workbench 1. The workbench 1 is arranged between the first wall panel 21 and the second wall panel 22. There are two workbenches, one high and one low. Here, the workbench 1 includes a first side plate 11 for connecting with the first wall panel 21, a second side plate 12 for connecting with the second wall panel 22, and a connecting plate 13 for connecting the first side plate 11 and the second side plate 12. A first guide rail 210 for facilitating the sliding of the first side plate 11 is arranged on the first wall panel 21, and a second guide rail 220 for facilitating the sliding of the first side plate 11 is arranged on the second wall panel 22; so that the workbench 1 is only connected to the side of the first wall panel 21 close to the second wall panel 22 and the side of the second wall panel 22 close to the first wall panel 21.

[0038] It should be noted that the specifications of the two workbenches 1 are the same, and both workbenches 1 are only connected to the side surfaces of the wall panels. Then, the side structures of the workbench 1, the first wall panel 21, and the second wall panel 22 are very simple and compact, without occupying the extra width of the entire laser cutting machine, and the overall bed structure is more compact, which is convenient for transportation.

[0039] Here, since the side structures of the first wall panel 21 and the second wall panel 22 are very simple and compact, the distance between the two guide rails for facilitating the sliding of the two workbenches 1 is not affected by other factors. Within the allowable side height range of the first wall panel 21 and the second wall panel 22, the distance between the two guide rails can be set larger. Generally speaking, the height difference between the two workbenches 1 is not less than 120 cm; it can meet the batch processing of most plates, and when the plate warps, it will not get stuck and interfere with the operation of the machine, making the laser cutting efficient.

[0040] Then, it is the setting of the motor part 3. The motor part 3 is arranged on the middle plate 23 at the end of the machine tool part 2, so that the motor part 3 is located between the first wall panel 21 and the second wall panel 22, without occupying the overall width of the entire machine tool part 2. The motor part 3 includes a motor main body 31 arranged on the middle plate 23, a driving wheel 32 connected to the motor main body 31, and a driving shaft rod 33 connected to the driving wheel 32. The driving shaft rod 33 is arranged parallel to the middle plate 23; the driving wheel 32 is connected to the motor shaft of the motor main body 31, and driving shaft rods 33 are arranged on both sides of the driving wheel 32, that is, when the motor main body 31 starts, it can drive the driving shaft rods 33 to rotate on both sides.

[0041] Finally, the motor part 1 drives the workbench to move, and the first wall panel 21 is provided with a first guide rail 210 for facilitating the sliding of the first side panel 11, and the second wall panel 22 is provided with a second guide rail 220 for facilitating the sliding of the first side panel 11. Of course, there are two first guide rails 210 and they are arranged in parallel up and down, so as to facilitate the sliding of the first side panels 11 of the two workbenches 2, and similarly, there are two second guide rails 220 and they are arranged in parallel up and down, so as to facilitate the sliding of the second side panels 21 of the two workbenches 2;

[0042] Here, the first wall panel 21 is provided with a first driving wheel 211 for connecting with the driving shaft 33 and a first chain 212 connected with the first driving wheel 211, and the second wall panel 22 is provided with a second driving wheel 221 for connecting with the driving shaft 33 and a second chain 222 connected with the second driving wheel 221; the first chain 212 is connected with the first side panel 11 of the working platform, and the first side panel 11 is provided with a first traction block 141 for connecting with the first chain 212; the second chain 222 is connected with the second side panel 21 of the working table, and the second side panel 12 is provided with a second traction block 142 for connecting with the second chain 222; so that the motor part 3 synchronously drives the two sides of the working platform to move synchronously.

[0043] Of course, there are two working platforms, which are respectively connected to the upper and lower sides of the chain, so that the two working platforms can be displaced alternately, that is, when one working platform moves forward from the lower position of the cutting head, the other working platform moves backward to the lower position of the cutting head.

[0044] The utility model discloses a parallel exchange laser cutting equipment with simple structure. The two work tables have the same design specifications, which reduces the required width of the work tables and makes the overall bed structure more compact. In addition, the motor for driving the displacement of the work tables is arranged on the inner side of the machine tool with a semi-hollow structure, which further reduces the occupied width of the overall bed structure, facilitates transportation, and has high displacement stability of the work platform.

[0045] Embodiment 2, still as Figures 1 to 9As shown, this is only one embodiment of the present utility model. Based on Embodiment 1, in a laser cutting device with parallel exchange of the present utility model, a laser cutting crossbeam 4 for facilitating the sliding of the cutting head is provided on the machine tool part 2; the laser cutting crossbeam 4 includes a crossbeam main body 41 and a base 42 provided at the end of the crossbeam main body 41; the crossbeam main body 41 includes a beam body 411 and a mounting plate 412 provided on the beam body 411 extending towards the base 42; the base 42 includes a base main board 421 and an adjusting plate 422 provided on the base main board 421, the adjusting plate 422 and the mounting plate 412 are arranged in parallel, and an adjusting bolt 423 for adjusting the distance between the mounting plate 412 and the adjusting plate 422 is provided on the adjusting plate 422.

[0046] The entire laser cutting crossbeam 4 is arranged on the laser cutting machine tool. The machine tool includes left and right side wallboards. The laser cutting crossbeam 4 is arranged on the upper side of the wallboards and the crossbeam structure is perpendicular to the wallboards; the laser cutting crossbeam 4 includes a crossbeam main body 41 and a base 42 provided at the end of the crossbeam main body 41. In fact, bases 42 are provided at both ends of the crossbeam main body 41, and the two bases 42 are respectively connected to the first wallboard 21 and the second wallboard 22; tracks for facilitating the sliding of the base 42 are also provided on the first wallboard 21 and the second wallboard 22, so that the entire laser cutting crossbeam 4 can slide along the extending direction of the wallboards, and the cutting head can slide on the crossbeam main body 41, so that the laser cutting head can be displaced to perform laser cutting on the plate on the workbench of the machine tool.

[0047] Tracks for facilitating the sliding of the base 42 are provided on the upper sides of the first wallboard 21 and the second wallboard 22. A base foot 424 is provided on the lower side of the base main board 421, and a dovetail groove is provided at the base foot 424 to facilitate the insertion of the track, so that the entire crossbeam structure can slide along the track.

[0048] The crossbeam main body 41 includes a beam body 411 and a mounting plate 412 provided on the beam body 411 extending towards the base 42. That is to say, the main beam column part of the crossbeam main body 41 is the beam body 411, forming a long strip columnar structure with a rectangular cross-section. A mounting plate 412 is provided on the lower side of the beam body 411 for connecting with the base 42.

[0049] Here, the beam body 411 includes an outer frame plate 4111 and a rib plate 4112 disposed within the space surrounded by the outer frame plate 4111. The outer frame plate 411 is actually formed by splicing two L-shaped bent plates end to end to form a hollow rectangular column structure, and the rib plate 4112 is disposed inside the hollow structure of this rectangular column, playing a role in supporting the outer frame plate 4111, making the entire beam body 411 structure stronger, effectively avoiding deformation of the cross beam and the laser cutting head during high-speed operation due to moving loads and impacts, which may affect the accuracy.

[0050] As an embodiment of the present invention, the base 42 includes a base main board 421 and an adjustment plate 422 disposed on the base main board 421. The base main board 421 is directly disposed on the upper side of the left and right side wall panels. The base main board 42 is parallel to the upper surface of the left and right side wall panels, and the adjustment plate 422 is disposed on the upper side of the base main 421.

[0051] As an embodiment of the present invention, the adjustment plate 422 and the mounting plate 412 are disposed in parallel. The adjustment plate 422 is provided with adjustment bolts 423 for adjusting the distance between the mounting plate 412 and the adjustment plate 422, that is, the distance between the mounting plate 412 and the adjustment plate 422 is adjusted by the adjustment bolts 423. When the number of adjustment bolts 423 is large, the distances at different positions between the mounting plate 412 and the adjustment plate 422 can be adjusted, that is, the angle between the beam body 411 and the base 42 is adjusted, so as to adjust the cross beam main body 41 to be perpendicular to the left and right side wall panels, that is, the perpendicularity at the connection between the cross beam main body and the base is adjusted, ensuring high cutting stability during the operation of the cross beam and guaranteeing the accuracy of the cutting head for cutting objects.

[0052] Here, the extending directions of the adjustment plate 422 and the mounting plate 412 are both parallel to the extending direction of the cross beam main body 41, so that the perpendicularity between the cross beam main body 41 and the extending direction of the machine tool can be effectively adjusted by turning the adjustment bolts 423.

[0053] Of course, the cross beam main body 41 and the base 42 are not only connected by the mounting plate 412 and the adjustment plate 422, but also connected by other connecting plates to ensure that the cross beam main body 41 effectively and stably carries the laser cutting head.

[0054] The number of the rib plates 4112 is at least two, and the included angle range between the two rib plates 4112 is from 0° to 180°, that is, multiple rib plates 4112 form included angles with each other, making the inside of the frame plate 4111 more stable, with a stronger structure and less prone to deformation. At the same time, a hollow hole is provided inside the rib plate 4112 to reduce the mass of the rib plate 4112. Besides ensuring the overall strength and rigidity of the cross beam main body, the weight of the steel structure is effectively reduced, the inertia during the operation of the cross beam main body is reduced, and further deformation of the cross beam is avoided.

[0055] As an embodiment of the present utility model, a slide rail for facilitating the sliding of the cutting head is provided on the beam body 411. The slide rail includes a first slide rail 4113 provided on the side surface of the beam body 411 and a second slide rail 4114 provided on the upper side of the beam body 411. The two slide rails make the sliding of the laser cutting head more stable; moreover, a strip plate 4115 is provided at the connection between the slide rail and the beam body 411. The strip plate 4115 can increase the strength at the guide rail surface, better ensure the processing accuracy, and make the sliding operation of the laser cutting head smooth.

[0056] As an embodiment of the present utility model, a limiting end plate 425 for connecting with the end of the beam body 411 is provided on the base main board 421. While restricting the end of the beam body 411, it can also prevent the hollow beam body 411 from being exposed and scratching people.

[0057] Here, a reinforcing inclined plate 426 is connected and provided between the base main board 421 and the limiting end plate 425 to ensure the structural stability of the limiting end plate 425.

[0058] It should be noted that a driving motor for driving the sliding of the base 42 is provided on the base 42, and the number of both the base 42 and the driving motor is two, that is, a driving motor is provided at each end of the crossbeam structure, so as to drive the synchronous sliding of both ends of the crossbeam structure. That is, the crossbeam adopts a double-motor driving method, and the sliding stability is higher.

[0059] Finally, both the crossbeam main body 41 and the base 42 are integrally formed welded parts; the crossbeam main body 41 is formed by welding manganese steel plates, and the structural strength is better.

[0060] In this way, the crossbeam main body has high strength, effectively avoiding the deformation of the crossbeam and the laser cutting head during high-speed operation due to movement loads and impacts, which affects the accuracy. Moreover, the verticality can be adjusted at the connection between the crossbeam main body and the base to ensure high cutting stability during the operation of the crossbeam, and the accuracy of the cutting head for cutting objects is guaranteed. On the premise of the stable structures of the first wallboard 21 and the second wallboard 22, combined with the stable operation of the workbench 1, the cutting effect of the plate is more accurate and the cutting efficiency is higher.

[0061] Embodiment 3, still as Figures 1 to 9 shown, is only one of the embodiments of the present utility model. On the basis of any of the above embodiments, in a laser cutting device with parallel exchange of the present utility model, two first driven wheels 213 for connecting with the first chain 212 are provided on the first wallboard 21; the height of the first driving wheel 211 is lower than the height of the first driven wheel 213.

[0062] Here, two first tensioning wheels 214 for connecting with the first chain 212 are arranged on the first wallboard 21, and the height of the first tensioning wheels 214 is between the height of the first driving wheel 211 and the height of the first driven wheel 213.

[0063] As an embodiment of the present utility model, an adjusting plate 215 for adjusting the height of the first tensioning wheel 214 is arranged on the first wallboard 21. An adjusting groove extending vertically is arranged on the adjusting plate 215. A part of the shaft rod of the first tensioning wheel 214 extends into the adjusting groove and is locked. For example, nuts are sleeved on both sides of the shaft rod and tightened against the side surface of the adjusting plate 215. When the height of the first tensioning wheel 214 needs to be adjusted, the shaft rod can be unlocked and loosened, and the height of the shaft rod can be adjusted manually or mechanically, and then the shaft rod is locked again.

[0064] Certainly, the first wallboard 21 and the second wallboard 22 are symmetrically arranged. That is to say, a second driven wheel 223, a second tensioning wheel 224 and a second adjusting plate 225 are also arranged on the second wallboard 22.

[0065] In addition, an installation bearing 231 for carrying the driving shaft rod 33 is arranged on the middle plate 23, so that the driving shaft rod 33 can be long enough to drive the chains on the two wallboards synchronously.

[0066] Finally, the first driving wheel 211, the first driven wheel 213 and the first tensioning wheels 214 are all gears, and the first wallboard 21 and the second wallboard 22 are both welded to the middle plate 23, so that the structural strength of the machine tool part 2 is guaranteed.

[0067] Embodiment 4, still as Figures 1 to 9 shown, is only one of the embodiments of the present utility model. On the basis of any of the above embodiments, in a laser cutting device with parallel exchange of the present utility model, tightening cylinders 25 for extending towards the workbench 1 are arranged on both the first wallboard 21 and the second wallboard 22; the number of the tightening cylinders 25 is four. In fact, there are four groups of tightening cylinders 25, and there are two groups on the first wallboard 21 and the second wallboard 22 respectively, just to tightly fix the workbench 1 in the working state, and the loading and unloading at the workbench 1 in the material changing state will not affect the cutting quality.

[0068] Certainly, a sub-bed body 24 for supporting the workbench 1 is also connected to the machine tool part 2. The sub-bed body 24 is located at the end of the machine tool part 2, and the workbench 1 in the material changing state is just located on the sub-bed body 24.

[0069] It should be noted that each set of clamping cylinders 25 is provided with two clamping heads, which are respectively used to clamp the sides of the two worktables 1, so that no matter which worktable 1 is in the working state, the clamping cylinder 25 can clamp the worktable 1 (of course, only one worktable 1 is in the working state, and the other worktable 1 is driven to the sub-bed 24 at the front end of the machine tool and is not in front of the clamping head).

[0070] In addition, a support grid plate 15 is arranged on the worktable 1 to reduce the heat absorption area of the worktable 1 during the cutting of the plate on the worktable 1 and avoid the thermal deformation of the worktable 1.

[0071] Finally, as a preference of the present invention, dust extraction ducts are arranged in both the first wall panel 21 and the second wall panel 22 for extracting the cutting smoke during laser cutting.

[0072] A laser cutting device with parallel exchange of the present invention has a simple structure. The two worktables have the same design specifications, which reduces the required width of the worktables. The overall bed structure is more compact. Moreover, the motor for driving the displacement of the worktable is arranged inside the machine tool with a semi-hollow structure, further reducing the occupied width of the overall bed structure, facilitating transportation, and having high displacement stability of the work platform.
