Specific implementation mode

To keep the purpose of this utility model, technical solution and advantage clearer, by the following examples to the utility model It is further described.

Fig. 1 is the schematic diagram according to the laser lamp calibrator 100 of the embodiments of the present invention.Laser lamp calibrator 100 Including pedestal 102, corrector strip 112 and calibrating stem 110.

There are pedestal 102 first jack 105 and at least three bolts 104, bolt 104 to be used for stationary base mount 102.To avoid Bolt 104 is lost, and bolt 104 can coordinate spring to use, to be retained on pedestal 102.Pedestal 102 can by aluminium section bar connect and At, or welded with other materials.

Corrector strip 112 has lock pin 114 and the first a pair of parallel graticule 118, and is pivotally mounted on around rotary shaft 109 In pedestal 102.First graticule 118 can be inserted into the first jack 105 perpendicular to rotary shaft 109, lock pin 114, to fixed calibration item 112。

There is calibrating stem 110 a pair of first telltale mark 140, the center of the first telltale mark 140 to be located at first straight line, and When lock pin 114 is inserted into the first jack 105, first straight line, the center line of the first graticule 118 and rotary shaft 109 are generally aligned in the same plane. The center line of first graticule 118 intersects with rotary shaft 109.In the present embodiment, first straight line is parallel to rotary shaft 109.

When calibrating the stationary laser lamp of 9 positions, lock pin 114 is passed through into corrector strip 112 and is inserted into the first jack 105, Pedestal 102 is fixed on the turntable of CT, and ensures the rotation overlapping of axles of rotary shaft 109 and turntable.Turntable is rotated, corrector strip is made 112 the first graticule 118 is horizontal, and the first telltale mark 140 of calibrating stem 110 is towards the stationary laser lamp.It opens It opens the laser lamp and adjusts its direction, until the laser plane of its injection passes through the first graticule 118 and calibrating stem of corrector strip 112 110 the first telltale mark 140.Laser plane precision as needed can suitably select the distance and first of the first graticule 118 The width of telltale mark 140.For the first graticule 118 at a distance of 2 millimeters, the width of the first telltale mark 140 is also 2 in the present embodiment Millimeter.

When calibrating the stationary laser lamp of 12 points, 3 positions, turntable is rotated, the first graticule 118 of corrector strip 112 is made to divide Other places are in vertical position and horizontal position, and the first telltale mark 140 of calibrating stem 110 is towards corresponding stationary laser lamp.It adjusts Section method is seen above.

In the present embodiment, pedestal 102 can have the second jack 106, lock pin 114 to can be inserted into the second jack 106, to solid Determine corrector strip 112.There is calibrating stem 110 a pair of second telltale mark 146, the center of the second telltale mark 146 to be located at second directly Line, and when lock pin 114 is inserted into the second jack 106, second straight line, the center line of the first graticule 118 and rotary shaft 109 are located at same Plane.Second jack 106 arrives the vertical line of rotary shaft 109 into 90 degree to the vertical line of rotary shaft 109 and the first jack 105.Due to having Second jack 106 of pedestal 102 and the second telltale mark 146 of calibrating stem 110, therefore calibrating the static of 9 positions After laser lamp, when calibrating the stationary laser lamp of 12 positions, it may not be necessary to rotary turnplate, but by corrector strip 112 with respect to pedestal 102 are rotated by 90 °, and lock pin 114 passes through corrector strip 112 to be inserted into the second jack 106.In the present embodiment, the second telltale mark 146 Width be also 2 millimeters.Another pair positioning mark is arranged in position that can also be opposite with the first telltale mark 140 on calibrating stem 110 Note, the stationary laser lamp for calibrating 3 positions.

In order to calibrate rotary laser lamp, corrector strip 112 can have the second a pair of parallel graticule 120, the second graticule 120 to hang down Directly in the center line of rotary shaft 109 and the second graticule 120 and 109 phase of rotary shaft from.In calibration rotary laser lamp, by corrector strip 112 Lock pin 114 unclamp, so that corrector strip 112 with flexible rotating or any angle can be maintained at.If rotary laser lamp is in corrector strip 112 The light of upper projection is located between two parallel lines of the second graticule 120, you can determines that the laser of rotary laser lamp projection is flat Face is perpendicular to rotary shaft 109.Second graticule 120 can be at a distance of 2 millimeters.

In the present embodiment, laser lamp calibrator 100 further includes casing 108.Casing 108 includes first neck 132 and the There is the first hole 124, pedestal 102 to have the second hole 116 for two necks 138, corrector strip 112.124 sets of the first hole of corrector strip 112 Set on casing 108 first neck 132 and fixed by the first nut 134, the second hole 116 of pedestal 102 is sheathed on casing 108 Second neck 138 is simultaneously fixed by the second nut 130.

There is second neck 138 a pair of of slot 128, calibrating stem 110 there is a pair of of positioning pin 142, calibrating stem 110 to pass through casing 108 hole 136 simultaneously makes positioning pin 142 be located in slot 128, and calibrating stem 110 is fixed by third nut 131, prevents calibrating stem 110 Axial movement.

In the present embodiment, pedestal 102 can have a pair of of clip 144, clip 144 that can house calibrating stem 110.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain within.
