Description

Technical Field

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

[0002] The laser cutting machine is a machine that focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to 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. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting. The connection mechanism for the laser cutting head is a mechanism that connects the laser cutting head and the laser cutting machine.

[0003] After searching, the patent number is CN212443805, which discloses a connecting component of the transmission mechanism of the cutting head of a laser cutting machine. The connecting component is provided with a hinged rod and a rotary sleeve. During installation, the hinged rod is rotated to make the teeth on the inner wall of the hinged rod mesh with the teeth on the first connecting block. At the same time, the rotary sleeve is rotated, and the rotary sleeve rotates and moves on the surface of the hinged rod, thereby fixing the position of the hinged rod to avoid looseness during use and affecting the stability of the fixed block. However, the device can only connect laser cutting heads of a single diameter, and its adaptability is relatively single, which is inconvenient to use. For this reason, we propose a connecting mechanism for a laser cutting head. Utility Model Content

[0004] The utility model aims to provide a connecting mechanism for a laser cutting head.

[0005] In order to solve the problems raised in the above-mentioned background technology, the utility model provides the following technical solutions: a connecting mechanism for a laser cutting head, comprising a laser cutting head, a fixed disk is installed on the upper end of the laser cutting head, a fixed column is installed at the center position of the upper end of the fixed disk, a first connecting end is installed on the upper end of the fixed disk, a plurality of groups of sliding boxes are arranged on the outer side of the first connecting end, a moving block is installed on the inner side of the plurality of sliding boxes, a first threaded column is installed on the outer side of the moving block, a first nut is installed on the outer side of the first threaded column, a second threaded column is installed on the lower end of the moving block, and a second nut is installed on the outer side of the second threaded column.

[0006] Preferably, the sliding box is slidably connected to the moving block.

[0007] Preferably, the first nut is threadedly connected to the first threaded column, and the second nut is threadedly connected to the second threaded column.

[0008] Preferably, the fixing column is located inside the first connecting end, and the fixing column is slidably connected to the first connecting end.

[0009] Preferably, a spiral column is installed at the upper end of the first connecting end, a rotating cylinder is arranged on the outside of the spiral column, a mounting disk is installed at the center position of the outside of the rotating cylinder, a motor is penetrated through the upper end of the mounting disk, a gear is installed on the upper end of the motor, a connecting column is installed on the upper end of the mounting disk, and a second connecting end is installed on the upper end of the connecting column.

[0010] Preferably, a gear block is fixedly connected to the outer side of the rotating cylinder, and the gear block is meshingly connected with the gear.

[0011] Preferably, a first slide plate is fixedly connected to the lower end of the mounting plate, and a second slide plate is slidably connected to the inner side of the first slide plate.

[0012] By adopting the above technical solution, by rotating the first nut, the fixation of the first nut and the sliding box disappears, and then the second nut is rotated to disengage the second nut from the second threaded column, and then the second threaded column is pulled to slide from the inside of the sliding box to the outside, and then it stops after sliding to a suitable distance according to the diameter of the fixed disk. At this time, the first nut is rotated to fix the first nut and the sliding box again, and then the laser cutting head is pushed to make the fixed disk and the fixed column slide into the second threaded column and the first connecting end respectively, and then the second nut is rotated to make the second nut fix the fixed disk with the cooperation of the first connecting end. At this time, the laser cutting head is fixed, otherwise it is loosened, so that the connection mechanism of the laser cutting head can connect and fix laser cutting heads of different sizes, thereby improving the adaptability of the connection mechanism of the laser cutting head.

[0013] By adopting the above technical solution, by starting the motor, the motor drives the rotating cylinder to rotate on the mounting plate with the cooperation of the gear and the tooth block, thereby driving the spiral column to push the first connecting end to move downward. At this time, when the first connecting end is moving, the laser cutting head connected to the first connecting end will descend with the first connecting end, stop when it descends to the required position, and rise otherwise. Through the cooperation of the first slide plate and the second slide plate, the lifting and lowering of the laser cutting head is more stable, and through the meshing connection between the gear and the tooth block, the laser cutting head will not slip during use, so that the laser cutting head can use the connecting mechanism to adjust the height of the laser cutting head according to the height of the cutting object, so as to facilitate the laser cutting head to perform precise cutting.

At this time, the fixation of the sliding box 5 by the first nut 8 disappears, so that the moving block 6 can slide inside the sliding box 5, and then the second nut 10 is rotated to disengage the second nut 10 from the second threaded column 9, so that the second nut 10 does not cause obstruction to the fixed disk 2, and then the second threaded column 9 is pulled to move outward. At this time, when the second threaded column 9 moves, it will drive the moving block 6 to slide inside the sliding box 5, and then stop after sliding to a suitable distance according to the diameter of the fixed disk 2, and then the first nut 8 is rotated to make the first nut 8 rotate on the first threaded column 7. , and move closer to the sliding box 5, so that the first nut 8 is fixed to the sliding box 5, so that the moving block 6 inside the sliding box 5 will not move, and then push the laser cutting head 1, so that the hole above the fixed disk 2 passes through the corresponding second threaded column 9, so that the fixed disk 2 fits with the lower end of the first connecting end 4, and the fixed column 3 slides into the first connecting end 4.
