Embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Shown in Fig. 1-3, a kind of laser spot test and laser energy apparatus for evaluating, comprise matrix 1, described matrix have a predetermined angle dip plane 10 and one for the benchmark bottom surface of welding plane contact, described dip plane is provided with the test sheet material 3 carrying out laser energy assessment for laser dotting, and described dip plane is provided with the distance for measuring different laser dotting and calculates the scale 4 of laser focal displacement; Described scale and described test sheet material parallel alignment are arranged on described dip plane.
Preferably, described benchmark bottom surface connects with the low side of described dip plane 10 and becomes predetermined angle.
Further, the entirety of described matrix is right angle trigonometry body shape.
Wherein, described matrix is connected as one by described dip plane and described test sheet material, and described scale is same with matrix to be connected as one, and is set in parallel on described dip plane with described test sheet material.
Practise physiognomy with welding plane and contact and fix in described benchmark bottom surface.
Further, described dip plane and benchmark bottom surface are respectively equipped with stationary installation 2, together with described test sheet material 3 is fixedly connected with dip plane 10, and described matrix 1 is fixed in described welding plane, ensures matrix and to weld plane contact good.
Further, described dip plane and benchmark bottom surface are respectively equipped with groove, described stationary installation 2 is arranged in described groove.
It should be noted that, described stationary installation can be body of magnetic material, and described stationary installation also can use double faced adhesive tape, or by other fixing stationary installation.
Wherein, in specific implementation, described matrix adopts carbon steel to be made.
It should be noted that, described test sheet material can select steel, also can select to weld material.
Due in the utility model, the bottom of described matrix has a certain degree with test sheet material, as 30 degree of angles, can fix at laser energy, laser head position is fixed, translation welding, thus by solder joint test sheet material on feed back the energy rule change determine focal position, by calculating focal length, the change also by its welding energy filters out preferably pad, by calculating, confirm welding focal length.
Described test sheet material 3 and scale 4 parallel alignment, as test quantitative criteria, test sheet material be used for laser dotting, scale for measure different laser energy get ready between spacing.
The utility model operation using method is as follows, see Fig. 4:
