Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a sensor for laser cutting machines. Background Art

[0002] Laser cutting involves focusing laser light emitted from a laser generator into a high-power, high-density beam through an optical system. The laser beam strikes the workpiece surface, 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 beam and workpiece move relative to each other, a slit is formed in the material, achieving the desired cutting effect.

[0003] Laser cutting machines generally use sensors during operation, but the existing technology generally installs sensors by fixing them to the cutting machine with bolts. The installation process requires operating multiple bolts in sequence, which is relatively complicated. In addition, it can only fix sensors of a specific size, reducing the adaptability of the device. There is no device to protect the sensor. During operation, if it is hit by external objects, the collision will directly act on the sensor, reducing the service life of the sensor. Utility Model Content

[0025] Reference Figure 1-5 , a laser cutting machine sensor includes a mounting plate 1, which is provided with a plurality of symmetrically arranged mounting holes 2 on the mounting plate 1, a mounting frame 3 is provided at the lower end of the mounting plate 1, and two symmetrically arranged fixing blocks 4 are provided at the bottom of the mounting frame 3. The upper ends of the two fixing blocks 4 are jointly provided with a fixing plate 5, and the upper end of the fixing plate 5 is provided with a sensor body 6. The fixing plate 5 and the lower end of the mounting frame 3 are both provided with a through slot 8, and the through slot 8 cooperates with the sensor body 6. The upper end of the fixing plate 5 is provided with a fixing mechanism for fixing the sensor body 6. The fixing mechanism includes a plurality of circumferentially arranged moving grooves 15 provided on the upper end of the fixing plate 5, and the plurality of moving grooves 15 are slidably connected with moving blocks 17, and the upper ends of the plurality of moving blocks 17 are provided with splints 7. By moving the plurality of moving blocks 17, the plurality of splints 7 are driven to move, so that the plurality of splints 7 contact the outer wall of the sensor body 6, thereby realizing rapid fixation of the sensor body 6 and enabling the device to fix sensor bodies 6 of different sizes, thereby improving the adaptability of the device.

[0026] The outer wall of the mounting frame 3 is provided with a protection mechanism for protecting it, the protection mechanism includes two symmetrically arranged through-rods 11 that are slidably connected on both sides and the rear end of the mounting frame 3, and baffles 12 are provided at the ends of multiple pairs of through-rods 11. Multiple baffles 12 are elastically connected to the mounting frame 3 through two springs 14, and multiple springs 14 are respectively sleeved on the outer walls of multiple through-rods 11. By utilizing the through-sliding connection between the through-rods 11 and the mounting frame 3, and the elastic action of the springs 14 between the baffles 12 and the mounting frame 3, the vibration generated by the impact is buffered, thereby preventing the vibration generated by the impact from directly acting on the sensor body 6, causing damage to the sensor body 6, and affecting the service life of the sensor body 6.

[0027] A connecting frame 13 is provided between each adjacent baffle 12 . The connecting frame 13 is L-shaped. The baffles 12 pass through both ends of the connecting frame 13 and are slidably connected thereto.

[0028] A rotating ring 18 is rotatably connected in the through slot 8 , and a damping gasket 21 is provided at the rotation connection between the rotating ring 18 and the through slot 8 .

[0029] Threaded rods 16 are rotatably connected between the plurality of movable grooves 15 and the through grooves 8 , and the plurality of threaded rods 16 respectively penetrate the plurality of movable blocks 17 and are threadedly connected thereto.

[0030] A bevel gear 20 is provided at the end of each of the threaded rods 16 , and a bevel gear ring 19 is provided at the upper end of the rotating ring 18 . Each of the bevel gears 20 is meshed with the bevel gear ring 19 .

[0031] A plurality of circumferentially arranged connecting rods 9 are provided at the lower end of the rotating ring 18 , and an operating ring 10 is commonly provided at the ends of the plurality of connecting rods 9 .

[0032] When the present invention is used, when the sensor body 6 is installed, the sensor body 6 is placed on the upper end of the fixed plate 5, and the operating ring 10 is rotated. Under the connection action of the multiple connecting rods 9, the operating ring 10 drives the rotating ring 18 to rotate (the setting of the damping gasket 21 between the rotating ring 18 and the through groove 8 limits the position of the rotating ring 18 after rotation), so that the bevel gear ring 19 at the upper end of the rotating ring 18 rotates, and the multiple bevel gears 20 are engaged with the bevel gear ring 19, so that the multiple bevel gears 20 rotate and drive the multiple threaded rods 16 to rotate. The threaded connection between the threaded rods 16 and the moving blocks 17 is used to move the multiple moving blocks 17 and drive the multiple clamping plates 7 to move, so that the multiple clamping plates 7 contact the outer wall of the sensor body 6, thereby achieving rapid fixation of the sensor body 6 and enabling the device to fix sensor bodies 6 of different sizes, thereby improving the adaptability of the device.

[0033] When the sensor body 6 moves with the cutting machine (the cutting machine is a prior art, so this figure does not elaborate on its related structure), when it collides with an external object, the vibration generated by the impact is buffered by the through-sliding connection between the through rod 11 and the mounting frame 3, and the elastic action of the spring 14 between the baffle 12 and the mounting frame 3, thereby preventing the vibration generated by the impact from directly acting on the sensor body 6, causing damage to the sensor body 6, and affecting the service life of the sensor body 6.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
