Description

Technical Field

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

[0002] Laser cutting is a high-precision and high-efficiency processing technology that uses a high-power density laser beam to irradiate the material to be cut, rapidly heating it to the vaporization temperature, thereby achieving the purpose of cutting.

[0003] The Chinese patent with application number CN202010566858.X in the prior art discloses an industrial laser cutting machine, including a machine tool, on which a cutting device is arranged, and a sliding groove is provided at a position of the machine tool corresponding to the cutting device, and the cutting device is movably connected to the machine tool through the sliding groove, and a placement seat is also provided on the machine tool, on which a sliding device is provided, and the sliding device includes an acceleration mounting seat, a steering mounting seat and a deceleration mounting seat, and a plurality of acceleration mounting seats are arranged in a rectangular array at the feed port position of the placement seat. The industrial laser cutting machine is difficult to push and place on the cutting station because the plate body to be cut is large and heavy, and it is difficult to stop due to its high inertia because of its high weight. The device is provided with a steering mounting seat and a deceleration mounting seat for coordinated use, and can decelerate the plate body in multiple stages, thereby decelerating the plate body multiple times to ensure that the plate body can be correctly placed on the cutting station.

[0004] The above scheme sets up a steering mount and a deceleration mount for coordinated use, which can decelerate the plate in multiple stages to ensure that the plate can be correctly placed on the cutting station. However, only one workpiece can be processed at a time, and re-loading and unloading are required after processing. The work efficiency is relatively low, which increases production time and cost. For this reason, we propose a laser cutting machine. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Example

[0037] See also Figure 1-Figure 4 , the technical solution provided by this embodiment is as follows:

[0038] The laser cutting machine comprises a base 1, a workbench 2, a slide rail 3, a pedestal 4, a mounting frame 5, a workstation 7 and a transfer mechanism, wherein: the workbench 2 is fixedly connected to the upper side of the base 1; the slide rail 3 is fixedly connected to the top of the workbench 2; the pedestal 4 is slidably arranged on the upper side of the slide rail 3; the mounting frame 5 is fixedly connected to the top of the pedestal 4, and lasers 6 are installed on both sides thereof; four workstations 7 are arranged and fixedly connected to the top of the base 1, and are symmetrically arranged on both sides of the workbench 2; the transfer mechanism is arranged on the lower side of the pedestal 4, and is used for switching the position of the laser 6 at double stations, and then performing multi-station continuous processing.

[0039] In the specific embodiment of the utility model, four workstations 7 are arranged in total, two in a group, and symmetrically arranged on both sides of the base 1. The slide rail 3 is used to limit the linear movement of the base 4, and then limit the mounting frame 5 and the laser 6. The mounting frame 5 is used to install the laser 6. The two lasers 6 are located in the same straight line. In the initial state, the lasers 6 are respectively located on two symmetrical workstations 7. When in use, the workpieces are placed on the workstations 7, and the two workpieces can be processed at the same time. After the processing is completed, the second bevel gear 15 is driven to rotate by the output end of the servo motor 14, and finally the turntable 10 is driven to rotate. The linkage block 11 rotates eccentrically with the turntable 10. Under the limitation of the straight groove cylinder 9, the base 4, the mounting frame 5 and the laser 6 move linearly as a whole, so that the laser 6 moves to the upper side of another workstation 7 to process another workpiece. Continuous processing can be achieved according to the above cycle. Compared with traditional single-station processing, two independent work processes or processing tasks are allowed to be carried out simultaneously, thereby significantly improving production efficiency, saving office space or production workshop space, and thus reducing layout costs. The process flow can be adjusted at any time according to different product requirements, and the flexibility is high.

[0040] Specifically, the transfer agencies include:

[0041] A straight groove cylinder 9, which is fixedly connected to the bottom of the base 4;

[0042] The turntable 10 is rotatably connected to the upper side of the workbench 2, and a linkage block 11 is fixedly connected to the top of the turntable 10, and the linkage block 11 is slidably connected to the straight groove cylinder 9;

[0043] A mounting shaft 12 is rotatably connected to the top of the base 1 and its upper end is fixedly connected to the turntable 10;

[0044] A first bevel gear 13 fixedly connected to the circumferential surface of the mounting shaft 12; and

[0045] The servo motor 14 is fixedly connected to the top of the base 1 , and the output end of the servo motor 14 is fixedly connected to the second bevel gear 15 , which is meshed with the first bevel gear 13 .

[0046] In a specific embodiment of the utility model, the servo motor 14 is located at the lower side of the workbench 2. When in use, the second bevel gear 15 is driven to rotate by the output end of the servo motor 14, the second bevel gear 15 drives the first bevel gear 13 to rotate, the first bevel gear 13 drives the mounting shaft 12 to rotate, the mounting shaft 12 drives the turntable 10 to rotate, and then drives the linkage block 11 to rotate eccentrically. Since the linkage block 11 slides in the straight groove cylinder 9, it drives the straight groove cylinder 9, the base 4, the mounting frame 5 and the laser 6 to move linearly, so that the laser 6 moves to the upper side of another workstation 7 to realize double-station processing.

[0047] Specifically, a sensor 18 is fixedly connected to the circumferential surface of the first bevel gear 13 , and two travel switches 17 are fixedly connected to the top of the base 1 , and the travel switches 17 correspond to the positions of different workstations 7 .

[0048] In a specific embodiment of the utility model, the sensor 18 is connected to the travel switch 17 by telecommunication. The position of the travel switch 17 corresponds to the position of the work station 7. When the sensor 18 moves to the travel switch 17, the servo motor 14 stops working. Similarly, the laser 6 moves to the work station 7 and stops, ensuring that the position of the laser 6 moves accurately and the processing quality is guaranteed.

[0049] Specifically, a sliding block 8 is slidably connected to the surface of the slide rail 3 , and the sliding block 8 is fixedly connected to the bottom of the base 4 .

[0050] In a specific embodiment of the present invention, two slide rails 3 and two sliders 8 are provided, close to the bottom sides of the base 4, and the sliders 8 slide linearly on the slide rails 3 following the base 4 to ensure that the base 4 can move stably.

[0051] Specifically, when the sensor 18 moves to the position of the travel switch 17, the servo motor 14 stops working.

[0052] In a specific embodiment of the present utility model, the sensor 18 is electrically connected to the travel switch 17. When the sensor 18 rotates following the first bevel gear 13, the sensor 18 stops when it moves to the position of the travel switch 17, thereby controlling the laser 6 to move to different workstations 7 and stop, and accurately controlling the moving position of the laser 6 to ensure the processing quality. It should be noted that the use of the above-mentioned servo motor 14, the travel switch 17 and the sensor 18 are all existing technologies and will not be elaborated in this solution.

[0053] Working principle: When in use, the workpiece is placed on the work station 7, and two workpieces can be processed at the same time. After the processing is completed, the second bevel gear 15 is driven to rotate through the output end of the servo motor 14, and finally the turntable 10 is driven to rotate. The linkage block 11 follows the eccentric rotation of the turntable 10. Under the limitation of the straight groove cylinder 9, the base 4, the mounting frame 5 and the laser 6 move in a straight line as a whole, so that the laser 6 moves to the upper side of another work station 7 to process another workpiece, thereby realizing continuous processing.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
