Inspection and adjustment device for cross-shaped laser measuring instruments

Abstract

The invention discloses an inspection and adjustment device for cross-shaped laser measuring instruments. The inspection and adjustment device comprises a calibration screen, CCD cameras, a conveyingline, a workbench and a robot device; high-precision ruler are arranged at the four peripheral edges of the calibration screen; the CCD cameras are arranged at different positions in front of the calibration screen; the conveying line is used for conveying the to-be-detected and detected cross-shaped laser measuring instruments; the workbench is arranged beside the conveying line; a positioning and clamping device is arranged on the workbench; the CCD cameras identify laser line position coordinates projected on the calibration screen, obtain the deviation and feed the deviation back to an industrial personal computer; and the industrial personal computer calculates the parameters comprising the torque and the rotation turns according to the deviation value so as to drive a screwdriver toperform adjustment until the deviation value meets the precision requirement. According to the inspection and adjustment device, automatic inspection and adjustment are realized; manual judgment and adjustment errors are eliminated, the assembling and adjusting precision can be improved, and the product quality consistency can be ensured; and automatic assembly line detection is adopted, and the productivity is remarkably improved.

Description

technical field [0001] The invention discloses a checking and adjusting device, in particular to a checking and adjusting device of a cross laser measuring instrument. Background technique [0002] The cross laser measuring instrument (laser measuring instrument or measuring instrument for short) is mainly composed of a pendulum, a horizontal and vertical laser head, a base, an adjustable foot, a fine-tuning screw, etc., and its product shape is as follows: figure 1 As shown, the internal structure is shown in Figure 2. The adjustable foot 6 and the base 5 are connected by bolts to ensure that the level of the base 5 and the angle with the horizontal plane can be adjusted; the bottom of the turntable 4 is equipped with a worm gear, which meshes with the worm on the fine-tuning screw 10, and rotates the fine-tuning screw. Then the vertical light position can be fine-tuned; three pillars 2 are installed on the turntable 4, the power supply board 9 is installed on the pillar 2...

Problems solved by technology

[0008] At present, the main adjustment method of the laser measuring instrument in the production still relies on the worker's human eye observation and manual adjustment of the adjustment screw of the laser head to ensure the levelness and plumbness of the horizontal line, but this method has low precision, low efficiency and labor intensity. high
