Problems solved by technology

Conventional surface difference measurement tools such as surface difference rulers cannot effectively reduce the measurement errors caused by local warpage and deformation of the board surface due to their small span and lack of data comparison capabilities of multiple measurement points at a single reference point; non-horizontal, vertical space planes or The surface difference measurement of regular surfaces is limited by factors such as measurement attitude, measurement surface gap, and measurement space, so it cannot be measured quickly and accurately
However, high-precision measuring equipment such as laser scanning molding is more expensive and requires higher skills for testers.
Therefore, it is not suitable for the routine detection of surface differences of excavator appearance parts

Abstract

The invention discloses a surface difference measuring device for an excavator outer part and a method thereof. The device comprises a magnetic base body, an angle adjusting mechanism arranged on the magnetic base body and a laser range finder inserted into the angle adjusting mechanism. The angle adjusting mechanism comprises a first adjusting mechanism fixedly installed on the magnetic base body, a stand column rotationally arranged in the first adjusting mechanism, and a second adjusting mechanism connected to the stand column in a sleeving mode. According to the invention, the laser range finder can be adjusted in span and multiple directions through the angle adjusting mechanism on the equipment, and simple and effective surface difference measurement can be carried out on some non-horizontal and vertical space planes or regular curved surfaces limited by factors such as measurement postures, measurement surface gaps and measurement space, so that more possibilities are provided for the design of a measuring method; measurement errors caused by local buckling deformation and the like can be effectively reduced, and the test precision is improved.

Description

technical field [0001] The invention belongs to the field of measuring systems for exterior parts of excavators, and in particular relates to a surface difference measuring device and method for exterior parts of excavators. Background technique [0002] Through the surface difference and gap between the exterior parts of the excavator, the design and assembly process level of the enterprise can be seen to a certain extent. As a large-scale construction machinery product, the excavator has a larger assembly gap than aerospace equipment and automobiles. Conventional surface difference measurement tools such as surface difference rulers cannot effectively reduce the measurement errors caused by local warpage and deformation of the board surface due to their small span and lack of data comparison capabilities of multiple measurement points at a single reference point; non-horizontal, vertical space planes or The surface difference measurement of regular surfaces is limited by ...
