Specific embodiment
As Figure 1-4, a kind of laser cutting machine, including the laser generator 20 that is fixedly installed on crossbeam 10 and sliding
The dynamic cutting head 30 being arranged on crossbeam 10, enters cutting head after the reflected unit reflection of the light beam that laser generator 20 sends
30, the crossbeam 10 is provided with slide rail 11, and slide rail 11 is provided with the first slide block 12 and the second slide block 13,12 He of the first slide block
The direction of motion synchronization of the second slide block 13, and the movement velocity of the first slide block 12 is the twice of 13 movement velocity of the second slide block；Institute
State cutting head 30 to be arranged on the first slide block 12, the reflector element includes the first speculum 41 being arranged on the second slide block 13
With the second speculum 42, the minute surface of first, second speculum 41,42 is mutually perpendicular to, and light beam is sequentially through first, second reflection
Mirror 41,42 enters cutting head 30 after reflecting, and the outgoing beam of the incident beam of the first speculum 41 and the second speculum 42 is equal
Parallel with 11 length direction of slide rail.First slide block 12 and the second slide block 12 can be respectively adopted a motor and be driven,
Again by the rotating speed of two motors of control, so that two slide blocks is moved by above-mentioned rule, but the method is relatively costly, the present invention recommends
Link gear described in following examples is realizing the differential cooperation of the first slide block 12 and the second slide block 13.Due to the first slide block 12
Movement velocity be the second slide block 13 twice, therefore, during motion, first is anti-for the first slide block 12 and the second slide block 13
The change of the change and 42 outgoing beam length of the second speculum of penetrating 41 incident beam length of mirror is just offset, it is ensured that whole
The stroke of light path keeps constant, and then guarantees that the beam intensity that cutting head is projected is uniform.
As Figure 1-3, as the preferred embodiments of the present invention, the 3rd slide block 14 is additionally provided with the slide rail 11, described
First slide block 12 is provided with both rigidity of connection Wei Yu second, third slide block 13,14 between second, third slide block 13,14
A synchronous pulley 131,141, two synchronous pulleys 131,141 are respectively equipped with connecting portion 16, and second, third slide block 13,14
Toothed belt transmission is constituted by cingulum 17 to coordinate, first slide block 12 is provided with for clamping wherein one flat segments of cingulum 17
The first clamping part 121, the crossbeam 10 is provided with the second clamping part 101 for clamping 17 another flat segments of cingulum.Should
In embodiment, only the first slide block 12 by Motor drive, slide with first in the presence of cingulum 17 by second, third slide block 13,14
Block 12 links, as shown in figure 3, the second slide block 13 and the 3rd slide block 14 are equivalent to two movable pulley mechanisms, the first slide block 12 is suitable
In the traction end of two movable pulley mechanisms, therefore the movement velocity of the first slide block 12 is the motion speed of second, third slide block 13,14
The twice of degree；The portion 16 that is rigidly connected is set between second, third slide block 13,14, it is ensured that relative distance therebetween is constant.Figure
In 3, when the first slide block 12 is moved right, the distance between the first slide block 12 and second slide block 13 are gradually increased, the second slide block
13 are gradually shortened with the distance of 11 right-hand member of slide rail, then as seen from Figure 4, during this incident beam of the first speculum 41 by
Tapered short, the outgoing beam of the second speculum 42 is progressively longer, and the speed and second that 41 incident beam of the first speculum shortens
The elongated speed sync of 42 outgoing beam of speculum, it is ensured that cutting head 30 is in moving process, the stroke of whole light path
It is constant；When the first slide block 12 is to left movement, the first slide block 12 draws the 3rd slide block 14 to left movement, 14 profit of the 3rd slide block
The second slide block 13 is promoted to move with the portion of being rigidly connected 16, now the distance between the first slide block 12 and second slide block 13 gradually contract
Short, the second slide block 13 is gradually increased with the distance of 11 right-hand member of slide rail, and therefore the incident beam of the first speculum 41 is elongated, and second is anti-
The outgoing beam for penetrating mirror 42 shortens, likewise, both cancel out each other, and then guarantees that whole light path stroke is constant.
