Problems solved by technology

[0004] It can be seen that this method is simple and direct for constructing the vehicle assembly reference line, but the use of steel wires to hang the weight is relatively primitive and backward, and the debugging process is cumbersome, which is not conducive to improving assembly efficiency; at the same time, the assembly reference line simulated by the wire drawing method is not stable enough , the interference of human factors is large and there is a straightness error, which has a significant impact on the assembly accuracy

Embodiment Construction

[0014] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0015] Such as figure 2 As shown, a laser positioning measurement system is used to determine the precise position of the left and right connecting parts 7, and then use the laser marking device to accurately construct the assembly reference line. Specifically, the left and right connecting parts 7 are fixed at a predetermined position at the rear of the vehicle body using an isosceles triangle tooling 1, and a first laser distance measuring and positioning device 3 and a second laser measuring and positioning device 3 are symmetrically arranged on both sides of the bottom of the isosceles triangle tooling 1. distance from the positioning device 4, and ensure that ...

Abstract

The invention discloses a laser positioning measuring system used to build a vehicle assembly baseline. The system comprises an isosceles triangle tooling fixed at a predetermined position of a tail of a vehicle body, and a left connecting part and a right connecting part of a vehicle are located at both sides of the bottom of the isosceles triangle tooling. The system also comprises a first laser range finding positioning device and a second laser range finding positioning device mounted on both sides of the bottom of the isosceles triangle tooling and symmetrical to each other, and a laser marking device. The invention also discloses a laser positioning measuring method.

Description

technical field [0001] The invention relates to the field of large-scale mechanical assembly detection, in particular, a laser positioning measurement system and method are designed. Background technique [0002] In the precision assembly process of large special vehicles, how to accurately construct the vehicle assembly reference line has always been a difficult problem in the assembly process. The current general method is to realize the positioning of the assembly reference line by using a special tooling wire method and a precision theodolite Construct. Such as figure 1 As shown, the left and right connecting parts are important parts of special vehicle assembly, and the design of the connection line between the left and right axle holes and the vehicle assembly datum line has strict requirements on perpendicularity. figure 1 In the middle, the two bottom corners of the special isosceles triangle tooling are used to fix the left and right connecting parts at the design...
