Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, specifically a rapid three-dimensional measuring instrument for aluminum workpieces. Background Technology

[0002] Aluminum processed parts refer to finished or semi-finished aluminum products with specific shapes, dimensions, precision, and performance characteristics, formed by various metal processing techniques such as rolling, extrusion, cutting, casting, welding, and surface treatment, using aluminum or aluminum alloys as raw materials. They are lightweight, corrosion-resistant, easy to process, and have excellent electrical and thermal conductivity.

[0003] The 3D dimension rapid measuring instrument is an intelligent inspection device that uses non-contact optical and image processing technologies such as laser scanning, structured light projection, and photogrammetry to quickly acquire 3D data of an object's surface and automatically analyze its size, shape, and tolerances. With the core objective of achieving high-efficiency, full-size automated measurement, it is widely used in online inspection and quality monitoring on production lines.

[0004] Existing three-dimensional rapid measuring instruments typically use guide rails to move the measuring device, enabling multi-directional measurement of workpieces. However, due to varying workpiece specifications depending on the application, and the fact that workpieces are generally placed on a worktable during measurement, inconsistencies in positioning and benchmarks can easily occur when measuring workpieces of different specifications. This leads to errors in the measurement results, affecting the accuracy and reliability of the inspection results. Therefore, this paper proposes a three-dimensional rapid measuring instrument for aluminum processed parts that eliminates the drawbacks of existing devices. Utility Model Content

[0025] The above embodiment discloses a rapid three-dimensional dimension measuring instrument for aluminum workpieces. In use, the workpiece is placed on the upper surface of the lifting bracket 2011. At this time, the first servo motor 206 is started to drive the first spur gear 208 to rotate.

At the same time, the bellows 2012 can protect the outer wall of the lead screw 201, effectively preventing external dust and other impurities from adhering to the outer wall of the lead screw 201. After the workpiece is raised to the specified height, the measuring probe 6 can be activated to measure the outer wall of the workpiece. During this process, the first moving component 4 can be activated to drive the support rail 7 to rotate, and the second moving component 5 can be activated to drive the measuring probe 6 to move along the outer wall of the support rail 7, so that the workpiece can be measured from multiple angles.
