Detailed Description

The following description of the present invention will be made in further detail with reference to the accompanying drawings 1-2.

When the laser scanning instrument is used, the laser scanning instrument needing to be measured is placed at the upper end of an inclined workbench 7, the laser scanning instrument tends to be horizontal when the base 1 is adjusted through the sole bolts 8 at the lower end of the control base 1, the base 1 is kept stable by controlling the extension length of each sole bolt 8, then the lifting platform 3 is controlled to lift, the height of the laser scanning instrument to be detected is adjusted, meanwhile, the receiving device used for receiving laser emitted by the laser instrument is fixedly connected to the side surface of the base 1, the height of the lifting platform 3 is controlled to enable the height of the laser instrument to correspond to the height of the receiving device, the scanning instrument is controlled to start working at the moment, the scanning instrument can emit laser and rotate along the vertical rotating shaft of the scanning instrument when working, meanwhile, the laser can be collected by the receiving device to judge the information of the laser scanning instrument, and the rotating center of the laser scanning instrument and the rotating center of the rotating workbench 5 need to be controlled in real time in the detection process When the position of the laser swinger to be detected needs to be adjusted, the position of the translation workbench 6 is adjusted, a screw rod is rotated during adjustment, the screw rod controls the translation workbench 6 to perform transverse direction translation motion through thread transmission in the rotation process, the self-locking performance of the screw transmission keeps the stability in the rotating process, so that the screw transmission can not be displaced due to external force, and when the unidirectional adjustment can not meet the requirement of accurate adjustment, the translation workbench 6 is designed into a plurality of layers, two adjacent layers are in sliding fit and are connected by using threaded rods, the threaded rods between the layers are arranged in a staggered manner, so that the adjustment of any angle can be realized, after the rotating center of the laser swinger is coincided with the rotating center of the rotating workbench 5, the lifting platform 3 is controlled to adjust the height, the self-locking function after stopping adjustment can be achieved and self-locking is carried out by adopting thread matching in the height adjusting process.

After the laser swinger is subjected to position adjustment, the lower end face of the laser swinger body is controlled to incline in the testing process, so that the automatic adjustment function of the laser swinger is tested, the inclined workbench 7 is controlled to incline to reach a set angle in the testing process, the translation workbench 6 is controlled to move to ensure that the rotation center of the laser swinger coincides with the rotation center of the rotation workbench 5, the lifting platform 3 is controlled to lift, so that a laser emission point of the laser swinger is positioned at a test point, so that the position calibration in the testing process is completed, the inclined workbench 7 is controlled to move to the set angle after the testing is completed, the data in the position is tested again, whether the laser swinger normally works or not is judged according to the measured result, and if an error exists, the magnitude of the error value is displayed, the movement distance of each component can be accurately adjusted in the measuring process, and judgment can be made from scales on the response component.

And when the adjusting screw 13 is rotated in the working process of the inclined workbench 7, when the adjusting screw 13 is rotated, because the left end of the adjusting screw 13 is rotatably connected to the inclined workbench 7, the other end of the adjusting screw is in threaded connection with the moving block 11, the moving block 11 can drive the moving block 11 to perform transverse sliding motion in the rotating process of the adjusting screw 13, the lower end of the moving block 11 and the inclined workbench 7 perform sliding motion, the upper end of the moving block 11 drives the inclined workbench 7 to perform inclined motion through the guide rail 12, the inclined workbench 7 can be jacked up by the moving block 11, because the moving block 11 is driven through the threaded transmission of the adjusting screw 13, the reverse acting force at the upper end of the inclined workbench 7 cannot enable the moving block 11 to move, and the displacement of the moving block 11 only depends on the rotation of the adjusting screw 13 to perform displacement.
