Second rotation is that 4 second rotation be fixed block 4-1 with first rotation is that the fixed block 3-1 that 3 first rotation is is connected; Simultaneously, the second plane mirror 2-2 by second redress microscope base 4-2 be fixed in second the rotation be on the fixed block 4-1; It is on the fixed block 4-1 that focus lamp 1-1 is fixed in second rotation by trim ring 1-2, and it is on the fixed block 4-1 that nozzle 1-4 is fixed in second rotation by lens barrel 1-3.When needing, second rotation is 4 can be arbitrarily angled around X-axis (second rotating shaft) rotation, thereby changes the inclination alpha of cutting head 1.
Preferably, first rotation is that 3 and second to rotate be to be connected by shaft coupling 7 between 4.Second rotation is that fixed block 4-1 is to be connected shaft coupling 7 between the fixed block 3-1 to connect with first rotation, and the two ends of shaft coupling 7 are that fixed block 3-1, second rotation are that fixed block 4-1 fixes by the pressure ring 8 and first rotation respectively.In other words, to be by the pressure ring 8 and first rotation that 3, second rotation is respectively 4 fixing for shaft coupling 7.When needed, second rotation is 4 can be arbitrarily angled around X-axis (second rotating shaft) rotation, and being fixed on first rotation by pressure ring 8 then is on 3.
In this cutter sweep 100, laser instrument emitted laser bundle is handled the back through a series of optical elements and is advanced along Y-axis; By carrying out vertical refraction one time on the anti-mirror 2-1 in first plane, laser beam is advanced along X-axis; Again by carrying out one time vertical refraction on the second plane mirror 2-2 again; By focus lamp 1-1 laser beam is focused on then, laser energy is concentrated on the focus; Penetrate by nozzle 1-4 at last.Utilize laser beam on workpiece 200, to move, just can realize cutting processing.
Above-mentioned cutter sweep 100, cutting head 1 can be around 360 ° of rotations of laser axis, also can adjust the inclination alpha of cutting head 1 on perpendicular to the direction of X-axis.Owing to have only two rotational freedoms, still have inconvenience during to workpiece 200 cuttings, so also can further improve.Specifically be to increase by the 3rd rotation system, make cutting head 1 have three rotational freedoms, make can be simultaneously along adjusting the inclination alpha of cutting head 1 on the direction of X-axis, thereby simplify the operation, be summarized as follows:
See also Fig. 3, this figure is the schematic diagram of laser cutting device second embodiment of the adjustable cutting angle of the utility model.As shown in Figure 3, in the cutter sweep 100, first rotation is that 3, second rotation is between 4, and connecting the 3rd rotation is 9; Wherein, the 3rd rotation is that 9 rotating shaft is the Z axle, and is definite by the right-hand rule between described Z axle and X-axis, the Y-axis, i.e. pairwise orthogonal between X-axis, Y-axis, the Z axle.
Similar with above-mentioned first embodiment, be that 3, second rotation is that the 4, the 3rd rotation is that the first plane mirror 2-1, the second plane mirror 2-2, the 3rd plane mirror 2-3 are set on 9 in first rotation respectively; Wherein: the planar quadrature that the minute surface of the first plane mirror 2-1 and Y-axis, Z axle are determined, the normal of the first plane mirror 2-1 and the angle between the Y-axis are 45 °; The planar quadrature that the minute surface of the second plane mirror 2-2 and X-axis, cutting head 1 longitudinal axis are determined, the normal of the second plane mirror 2-2 and the angle between the X-axis are 45 °; The planar quadrature that the minute surface of the 3rd plane mirror 2-3 and X-axis, Z axle are determined, the angle between the normal of the 3rd plane mirror and the Z axle is 45 °.
The above-mentioned first plane mirror 2-1, the second plane mirror 2-2, the 3rd plane mirror 2-3 are set; After, laser beam just can transmit according to the route of laser optical axis → Y-axis → Z axle → X-axis → cutting head 1 longitudinal axis.Specifically be that laser beam advances along laser optical axis (Y-axis); Be mapped to the first plane mirror 2-1 and go up vertical refraction of generation, make laser beam advance along the Z axle; Be mapped to the 3rd plane mirror 2-3 and go up generation secondary vertical refraction, make laser beam advance along X; Be mapped to the second plane mirror 2-2 three vertical refraction take place, make laser beam advance, converge until a focus lamp 1-1 who is cut on 1 along cutting head 1 longitudinal axis.
According to above-mentioned light path conducting 2, can the strict guarantee laser beam transmit according to the route of laser optical axis → Y-axis → Z axle → X-axis → cutting head longitudinal axis; The arbitrary spool rotation of cutting head 1 in X-axis, Y-axis, Z axle, laser beam can not change transmission route; Thus, adjust the angle of laser head 1, just can adjust the cutting angle of workpiece 200, realize workpiece 200 being cut from arbitrarily angled.
In the present embodiment, cutting head 1 is provided with three rotational freedoms, and it can adjust the angle of cutting head 1 and workpiece 200 easily around arbitrary rotation in X-axis, Y-axis, the Z axle.Specifically: rotate around Y-axis, adjust the azimuth of cutting head 1; Rotate around X, adjust the inclination angle of cutting head 1 on perpendicular to the direction of X-axis; Around the rotation of Z axle, on the direction of X-axis, adjust the inclination angle of cutting head 1.Owing to can on both direction, adjust the inclination angle of cutting head 1, can adjust the angle of cutting head 1 and workpiece 200 more easily, can improve the efficient of cutting thus.
