Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to an adjustable laser cutting machine. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. This beam irradiates the surface of the workpiece, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas, coaxial with the beam, blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is ultimately formed in the material, thus achieving the purpose of cutting.

[0003] Existing laser cutting machines need to handle various specifications of materials to be cut, including multiple materials with different thicknesses or the same material with varying thicknesses. Therefore, the cutting height or cutting power of the laser cutting machine needs to be adjusted to achieve an effective cutting result. However, existing materials lack intuitive and real-time thickness measurement mechanisms, making it inconvenient for operators to make timely adjustments to the laser cutting machine.

[0004] Therefore, we propose an adjustable laser cutting machine to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Reference Figure 1-5 An adjustable laser cutting machine includes a machine base 1, which is used to set up on a horizontal ground to provide stable support. A crossbeam 2 is horizontally mounted on the upper side of the machine base 1, and a cutting head 3 is mounted on the crossbeam 2. Support frames 4 are fixed to both sides of the crossbeam 2, and several electrically operated telescopic rods 5 are evenly and equidistantly fixed to the support frames 4. The telescopic ends of the electrically operated telescopic rods 5 face downwards and are fixed with abutment blocks 8. The several electrically operated telescopic rods 5 can precisely control the downward movement of the corresponding abutment blocks 8.

[0027] The machine base 1 has a rectangular cavity in the middle, and several laser racks 6 are installed in the cavity. The upper side of the laser racks 6 is used to place the raw material body 7, and the lower side of the laser racks 6 is provided with abutting mechanism for abutting against the raw material body 7. The abutting block 8 can move downward to contact and abut against the surface of the raw material body 7, and the abutting mechanism can also abut against the bottom of the raw material body 7, ultimately achieving a stable clamping effect on the raw material body 7.

[0028] For the above example, those skilled in the art should know that when implementing the above technical solution, the cutting head 3, i.e. the laser emitting device, emits a laser, which is focused into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, which can make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0029] For the above example, those skilled in the art should know that when implementing the above technical solution, the raw material body 7 is the raw material workpiece to be cut and processed.

[0030] As a technical optimization of this utility model, a housing 9 is fitted onto the crossbeam 2, and a hydraulic telescopic arm 10 is installed at the bottom of the housing 9. The cutting head 3 is fixedly connected to the bottom of the hydraulic telescopic arm 10. The hydraulic telescopic arm 10 is used to precisely control the lifting and lowering adjustment of the cutting head 3.

[0031] For the above example, those skilled in the art should know that when implementing the above technical solution, the two ends of the crossbeam 2 are matched with existing drive mechanisms, and the crossbeam 2 can move precisely horizontally on the machine base 1. Similarly, the housing 9 is also matched with a corresponding drive mechanism, and the housing 9 can move precisely horizontally on the crossbeam 2.

[0032] As a technical optimization of this utility model, the support frame 4 is C-shaped, and the shell 9 is located inside the range of the support frame 4. That is, the support frame 4 will not affect the movement of the shell 9, and the support frame 4 can move with the movement of the crossbeam 2 without affecting the normal cutting.

[0033] As a technical optimization of this utility model, a ruler strip 11 is vertically fixed to one side of the machine base 1. The ruler strip 11 has scale markings. A laser marking device 12 corresponding to the ruler strip 11 is fixed to the telescopic end of one of the electric telescopic rods 5. The laser marking device 12 is an existing marking device that can emit a straight, horizontally positioned laser line. When the laser line appears on the ruler strip 11, it can accurately correspond to the scale markings on the ruler strip 11. When the electric telescopic rod 5 extends and retracts, it can synchronously drive the laser marking device 12 to move, and the corresponding light also moves along the ruler strip 11. The distance the light moves can be accurately determined by the ruler strip 11, and this distance is the thickness of the raw material body 7. Each electric telescopic rod 5 can be equipped with a laser marking device 12 and matched with a ruler strip 11.

[0034] As a technical optimization of this utility model, a plurality of laser racks 6 are arranged in parallel at equal intervals, and the bottom of each of the laser racks 6 is detachably and fixedly connected to a mounting frame 13, which is horizontally fixed in the cavity of the machine base 1.

[0035] For the above example, those skilled in the art should know that when implementing the above technical solution, several laser racks 6 play a role in positioning and support. Their main function is to fix the raw material body 7, ensure that its position does not move, and prevent the raw material body 7 from being burned by the laser.

[0036] As a technical optimization of this utility model, the abutting mechanism includes a rectangular frame 14 parallel to the bottom of the machine base 1. Several cylinders 15 are arranged in a matrix on the rectangular frame 14, with their extension and retraction ends facing upwards and fixed with support blocks 16. The rectangular frame 14 can be detachably and fixedly connected to the cavity of the machine base 1. The cylinders 15 are used to synchronously start and control the corresponding support blocks 16 to rise until the support blocks 16 are flush with the upper side of the machine base 1, thus abutting against the bottom of the raw material body 7 which is horizontal at the bottom. If the bottom of the raw material body 7 is uneven, the cylinders 15 can be adjusted as needed so that the support blocks 16 can also contact and abut against the uneven bottom of the raw material body 7.

[0037] For the above example, those skilled in the art should know that when implementing the above technical solution, the number of cylinders 15 on the rectangular frame 14 can be set according to the needs to ensure that they are matched with the larger specification raw material body 7.

[0038] As a technical optimization of this utility model, the elevation of the several support blocks 16 does not exceed the bottom height of the mounting frame 13, and the several horizontally arranged support blocks 16 are all located between two laser racks 6, so that the lifting and lowering of the support blocks 16 will not be blocked by the laser racks 6.

[0039] In this invention, the working principle of the device is as follows:

[0040] After the raw material body 7 is placed on the machine base 1 and aligned with the position of the crossbeam 2, several electric telescopic rods 5 are activated. The corresponding abutment blocks 8 move downwards to contact and abut against the surface of the raw material body 7. Meanwhile, several cylinders 15 located below drive several support blocks 16 to rise and abut against the bottom of the raw material body 7. This achieves a stable clamping effect on the raw material body 7. After clamping, the corresponding laser marking device 12 emits a horizontally positioned laser line. When this laser line appears on the ruler 11, it accurately corresponds to the scale on the ruler 11. The distance between the light beam and the initial position is the distance moved, and this length is the thickness of the raw material body 7. Through precise movement of the thickness, the cutting height or cutting power of the cutting head 3 can be set and adjusted to achieve a good cutting effect. Furthermore, for subsequent processing operations of raw material bodies 7 of the same specifications, no further measurement is required; cutting can be performed according to the set adjusted state.

[0041] Furthermore, in the above operations, each electric telescopic rod 5 can be equipped with a laser marking device 12 and a matching ruler 11, facilitating the measurement of different thicknesses of the raw material body 7. After thickness measurement, during cutting, the support frame 4 will not affect the movement of the housing 9, i.e., it will not affect normal cutting, and can effectively clamp and fix the raw material body 7. When repositioning is required, the electric telescopic rod 5 can be activated to retract the corresponding abutment block 8 without affecting the movement of the crossbeam 2. Additionally, if the bottom of the raw material body 7 is uneven, several cylinders 15 can be adjusted as needed, allowing several support blocks 16 to contact and abut against the uneven bottom of the raw material body 7, ensuring accurate thickness measurement.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
