A base plate which uses steel balls as supporting points and is used for installing a laser device can do X, Y axial plane rotations. An elongated slot is arranged in a laser device seat. The laser beam of the utility model can complete three freedom degree regulations of angular displacement, translation and rotation. The utility model enhances positioning accuracy and has the advantages of convenient installation and convenient operation.

Description

The laser positioning instrument

The utility model relates to a kind of location instrument, particularly relates to two groups of laser beam of a kind of application, the laser positioning instrument that joint is located on object.

The laser positioning instrument that adopts the intersection point of two projection straight line of two groups of covering of the fan laser beam on positioning object the to locate occasion that is widely used, this kind instrument requires the straight line of every group of laser beam projection can independently finish translation, the regulatory function that rotation angle is moved, the adjusting between two groups is not interfered.The general at present laser positioning instrument that uses can only be regulated the emission angle of every group of laser covering of the fan, can not translation and rotating and projection straight line.As enlarging range of adjustment, translation and rotating and projection straight line, complete machine base position that must the running fix instrument, but be subjected to the restriction of base position mounting hole, moving range is less, and the precision extreme difference.

In order to overcome the deficiency of laser positioning instrument commonly used, need design a kind of simple in structure, bearing accuracy is higher.Fitting operation is the laser positioning instrument of adjusting mechanism easily.

The utility model work principle is difference thread connection set screw A1 and set screw B1 on substrate D, one steel ball C is arranged as two strong points of pulling in the groove between substrate D and base plate E, A2, A3 are extension springs, be separately fixed on substrate D and the base plate E at two ends on the axis of A1-C, B2, B3 are extension springs, be separately fixed on substrate D and the base plate E at two ends on the axis of B1-C, the effect of four extension springs is to guarantee that the contact of the point of A1, B1, C is reliable.When set screw A1, can along the line of 2 of B1 and C the axis rotation between plate D and the plate E, when set screw B1, can be that axle rotates along the line of 2 of A1 and C between plate D and the plate E.Use above-mentioned principle of work, the utility model is realized with following technical scheme: the X-axis set screw A1 that a thread connection is arranged above substrate D, the Y-axis set screw B1 that one thread connection is arranged in the lower right, two screws withstand on respectively on the corresponding base plate E, one steel ball C is arranged in the pit between substrate D and the base plate E, extension spring A2 is installed on the line of A1-C, A3, the extension spring two ends are fixed with substrate D and base plate E respectively, extension spring B2 is installed on the line of B1-C, B3, the extension spring two ends are fixed with substrate D and base plate E respectively, the pitch of difference set screw A1 or B1, substrate D is rotated with the rotation of A1-C axle or with the B1-C axle with respect to base plate E, thereby the covering of the fan laser beam that makes the laser instrument ejaculation that is loaded on the substrate D is along X-axis or the displacement of the Y-axis angle of parallelism, for making two fan planar laser beams of location usefulness, except angular displacement, also suitably translation, more can improve bearing accuracy, horizontal down perpendicular two grooves on having on the substrate D, two translation slide plate A4 and B4 are installed, the A4 slide plate is contained in the vertical chute, be fixed on the substrate D by the dog screw A6 in the right and left symmetry long slot bore, the B4 slide block is contained in the horizontal concrete chute, on the fixing substrate plate D of the dog screw B6 in the laterally zygomorphic long slot bore, for the emitted fan planar laser beam of laser instrument A and laser instrument B can also be rotated where necessary, dog screw A7 in the symmetrical up and down arc-shaped slot of the laser socket A5 of interior dress laser instrument A is fixed on the slide plate A4, dog screw B7 in the left-right symmetric arc-shaped slot of the laser socket B5 of interior dress laser instrument B is fixed on the slide plate B4, after translation becomes rotation to regulate, screwed in place screw A6, B6, A7, B7.

Advantage of the present utility model is to have increased translation and rotational structure, and not mobile instrument base position just can enlarge the orientation range and the bearing accuracy of this kind instrument, and two groups of laser beam can be regulated separately, do not disturb mutually; Having improved is X, the Y-axis governor motion of fulcrum with the steel ball, and two groups of laser beam can be regulated simultaneously, and the adjusting of orientator, operation are more become conveniently, and precision improves.

Below in conjunction with embodiment accompanying drawing of the present utility model is further described:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a left view of the present utility model;

Fig. 3 is a fundamental diagram of the present utility model.

Embodiment: according to the principle of work of Fig. 3 on the base plate E that metal material is made, Laser Power Devices F and laser beam governor motion two parts are installed, form a cover laser positioning instrument, but the laser beam governor motion is the A by the substrate self contained function, B, two groups of laser beam transmitters on the D are formed, the fan planar laser beam of laser instrument A emission is horizontal, the fan planar laser beam of laser instrument B emission is vertical configuration, on Fig. 2 and Fig. 1 as can be seen, slide plate A4 matches with the substrate D straight runner, the screw A6 of the location in the symmetrical long slot bore of slide plate A4 is fixed on the substrate D, slide plate A4 can upper and lower translation, to the appropriate location, tighten screw A6 location, the round bottom seat of laser socket A5 slides in the center pit of slide plate A4, dog screw A7 in the arc-shaped slot up and down of laser socket A5 is fixed on the slide plate A4, laser socket A5 can do relative rotation with slide plate A4, after forwarding correct position to, tighten screw A7 location, kindred circumstances, slide plate B4 matches with the sideslip groove of substrate D, dog screw B6 in the laterally zygomorphic long slot bore of slide plate B4 is fixed on the substrate D, slide plate B4 can left and right sides translation, during to the appropriate location, screwed in place screw B6 location, the round bottom seat of laser socket B5 slides in the center pit of slide plate B4, dog screw B7 in the left and right sides arc-shaped slot of laser socket B5 is fixed on the slide plate B4, laser socket B5 can do relative rotation with slide plate B4, forward correct position to after, tighten screw B7 location.In conjunction with Fig. 1, Fig. 2, Fig. 3, at the upper end of substrate D thread connection X-axis set screw A1, right-hand member thread connection Y-axis set screw B1 at substrate D, settle a steel ball C between substrate D and base plate E by the perpendicular line of A1 with by the horizontal intersection point of B1, in the middle of the A1-C line between substrate D and the base plate E, evenly arrange extension spring A2, A3, the two ends of extension spring are separately fixed on two plates, in the middle of the B1-C line, evenly arrange extension spring B2, B3, the two ends of extension spring are separately fixed on two plates, when fine setting set screw A1 or B1, substrate D is made X axis or Y-axis to rotating relative to base plate E.Drive that laser instrument A on the substrate D and laser instrument B penetrate two groups vertical and laser straight lines level move to anchor point and hand over adoptedly on the object that is positioned, reach the purpose of location.
