Embodiment 1

[0051] combine figure 1 , a double pendulum three-dimensional laser cutting machine in this embodiment includes a focus adjustment mechanism 200, a first reflection mechanism 400, a second reflection mechanism 600 and a cutting head 900, wherein the first reflection mechanism 400 is arranged at the center of the focus adjustment mechanism 200 Below, the laser beam transmitted in the focusing mechanism 200 is reflected, passed through the swing mechanism 500, and then directed to the second reflection mechanism 600, and then reflected by the second reflection mechanism 600 to the cutting head 900, and then emitted by the cutting head 900 to process the workpiece to be processed. laser cutting. During the whole laser cutting process, such as figure 1 As shown, when processing parts in different positions, the parts below the focusing mechanism 200 can rotate axially, and the swing mechanism 500 between the first reflecting mechanism 400 and the second reflecting mechanism 600 c...

Embodiment 2

[0055] A kind of double-pendulum three-dimensional laser cutting machine of this embodiment is basically the same as Embodiment 1, and its difference is: combined figure 2 , image 3 and Figure 4 , the focusing mechanism in this embodiment includes a focusing lens barrel 230, a collimating lens holder 233 and a first composite lens 234, wherein a fixing seat 220 is fixedly installed above the focusing lens barrel 230, and a mirror is arranged on the fixing seat 220. Barrel 210, lens barrel 210 is connected with focusing lens barrel 230, and focusing lens barrel 230 is connected with lens barrel 2 240 at the bottom of focusing mechanism 200, which is convenient for laser beam to pass through; 233, the collimating lens mount 233 is set in the cavity of the focusing lens barrel 230, such as image 3 As shown, in order to facilitate the adjustment of the focus position, a hole is opened on the focusing lens barrel 230 in this embodiment, and the adjusting dial 232 is inserted ...

Embodiment 3

[0058] A kind of double-pendulum three-dimensional laser cutting machine of this embodiment is basically the same as Embodiment 2, and its difference is: in this embodiment, in order to further ensure that the focus position of the laser beam will not changes happened. Such as image 3 and Figure 4 As shown, in this embodiment, a guide groove 236 is provided on the outer wall of the collimating lens base 233 along its height direction, and a fixing hole 235 is provided on the focusing lens barrel 230. When the adjusting dial 232 is rotated, the laser beam After the focus is adjusted, the fixing piece is inserted into the fixing hole 235 and connected with the guide groove 236 . On the one hand, the fixing member in this embodiment can fix the collimating lens base 233 in the inner cavity of the focusing lens barrel 230 to prevent it from moving, that is, when the focusing mechanism 200 rotates, the focusing mechanism is stably fixed on the focusing lens barrel 230 inner ca...

Abstract

The invention discloses a double-pendulum three-dimensional laser cutting machine, and belongs to the technical field of laser cutting. The double-pendulum three-dimensional laser cutting machine comprises a focusing mechanism, a first reflection mechanism, a second reflection mechanism and a cutting head. The focusing mechanism is located below a laser inlet, a focusing unit is arranged in the focusing mechanism, a following mechanism and a beam-focusing mechanism are arranged between the second reflection mechanism and the cutting head, the following mechanism is used for driving the beam-focusing mechanism and the cutting head to wholly move up and down, the beam-focusing mechanism is used for adjusting the direction of the light beam, and the laser beam is emitted out of the cutting head. The focusing unit, the following mechanism and the beam-focusing mechanism are arranged, and are matched to jointly adjust the focus point position of the laser beam, it is ensured that the focuspoint position is in the surface of a workpiece to be machined all the time, and the laser cutting is facilitated.

Description

technical field [0001] The invention relates to the technical field of laser cutting, and more specifically relates to a double pendulum three-dimensional laser cutting machine. Background technique [0002] As a new type of cutting technology, laser cutting has been widely used due to its advantages of fast cutting speed, high production efficiency, good cutting surface quality, small heat-affected zone and environmental protection. The entire laser cutting process is: under the excitation and drive of the CNC program, the laser emits laser light from the laser generator, transmits it to the cutting head through the optical path system, and focuses on the surface of the workpiece to be cut, and melts the surface of the workpiece at the focus ;At the same time, the nozzle ejects auxiliary gas from the direction parallel to the beam to blow away the slag; under program control, driven by a servo motor, the cutting head moves according to a predetermined route, thereby cutting...
