Description

Technical Field

[0001] The utility model relates to the technical field of workpiece rotating mechanisms, in particular to a workpiece rotating mechanism of a 3D laser scanner. Background Art

[0002] The working principle of a 3D laser scanner is to use a laser beam to scan the target object, measure the time and position information of the laser beam reflected back, and thus determine the shape and structure of the object's surface. Different types of 3D laser scanners have different scanning accuracy, speed, and applicable fields. You can choose the appropriate equipment according to specific needs. When using a 3D laser scanner, it is generally necessary to use a workpiece rotation mechanism to place the workpiece and adjust the position of the workpiece, so that the 3D laser scanner can fully and accurately collect the information of the workpiece.

[0003] However, in the prior art, after the workpiece rotation mechanism fixes the workpiece, it can generally only rotate in the horizontal direction and cannot stably rotate the workpiece in the vertical direction. When it is necessary to collect information about the top and bottom of the workpiece, the workpiece needs to be removed and fixed again, so that the information on the top and bottom cannot be fully collected, resulting in a decrease in the efficiency of the 3D laser scanner in collecting workpiece information. In addition, the operation method of fixing the workpiece for the second time and then scanning it is easy to cause the accumulation of errors in the collected data, resulting in an increase in the error of the collected workpiece information.

[0024] The specific configuration and function of this embodiment are described in detail below. When the workpiece needs to be rotated, the first servo motor 12 drives the rotating frame 13 to rotate in the horizontal direction, thereby completing the angle adjustment of the workpiece in the horizontal direction. The second servo motor 14 drives the bar slide 21 to rotate in the vertical direction, thereby rotating the workpiece in the vertical direction. By fully rotating the workpiece in the horizontal and vertical directions, the 3D laser scanner can collect comprehensive information on the workpiece fixed on the upper part of the fixing mechanism 2.

[0025] When the No. 1 servo motor 12 drives the rotating frame 13 to rotate, the No. 1 connecting plate 17 will drive the No. 1 annular slider 16 to rotate along the No. 1 annular slide rail 15, and the No. 1 annular slide rail 15 will limit the horizontal rotation of the rotating frame 13, thereby improving the stability of the rotating frame 13 and the workpiece during horizontal rotation.

After the position of the clamping plates 28 is adjusted appropriately, the cylinder 25 pushes the push frame 26 and the clamping plates 28 at the bottom thereof to limit and fix the workpiece. In the process of the clamping plates 28 clamping and fixing the workpiece, the telescopic rod 210 and the spring 211 produce compression deformation;

[0030] When the workpiece needs to be rotated, the first servo motor 12 drives the rotating frame 13 to rotate in the horizontal direction, thereby completing the angle adjustment of the workpiece in the horizontal direction, and the second servo motor 14 drives the bar slide 21 to rotate in the vertical direction, thereby rotating the workpiece in the vertical direction.
