Embodiment Construction

[0035] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as figure 1 As shown, the full-surface three-dimensional measuring device for complex columnar workpieces of the present invention includes: a sensor assembly 1, a linear module 2, a loading fixture 6, a blanking mechanical arm 3, a blanking belt line 4, a calibration block and a controller; :

[0037] The sensor assembly 1 is composed of three line laser displacement sensors. The three sensors are not on the same plane. When installing, ensure that the distance between the sensor laser line and the 5 axis of the measured workpiece is about 4mm, and the three sensors are installed at an angle of 120 degrees to each other. .

[0038] The linear module 2 is composed of a linear motor and a bracket, and the sensor combination is fixed on the br...

Abstract

The invention discloses a full-surface three-dimensional measurement device of a complex cylindrical workpiece, and a measurement method thereof. Three line laser displacement sensors forming an angle of 120 degrees with one another are installed together to form a sensor assembly, after the three sensors are calibrated, relative space positions of the three are determined, and acquisition data of the three are enabled to be under the same coordinate system; and the sensors are combined and installed on a linear motor, a controller controls the linear motor to drive the sensor assembly to move and trigger the sensor assembly at equal intervals to acquire surface position data of a detected workpiece. According to the invention, through comparing actual data and designing a three-dimensional model, such geometric features of the detected workpiece, such as the length, the diameter, the profile tolerance, the cylindricity and the like are obtained so that problems occurring in the technical process of the complex cylindrical workpiece can be accurately positioned and analyzed.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional measurement, and in particular relates to a full-surface three-dimensional measurement device for complex columnar workpieces and a measurement method thereof. Background technique [0002] With the rapid development of advanced manufacturing automation production technology and the continuous improvement of product quality control system, people have higher and higher requirements for the accuracy, efficiency and automation of the detection of the geometric size and shape position of the processing object, especially the part shape The complexity of the measurement and the on-site and real-time performance of the measurement pose new challenges to the traditional precision measurement technology. In some specific occasions, such as real-time online detection of surface contours, tiny dimensions and complex part features, etc., has become a difficult problem faced by traditional detectio...
