Description

Technical Field

[0001] The utility model relates to the field of size detection equipment, in particular to a workpiece positioning turntable for size detection equipment. Background Art

[0002] Dimensional inspection equipment is primarily used to determine the size, shape, position, and other geometric characteristics of objects to ensure they meet design requirements or manufacturing standards. Through precise measurement techniques, these devices can detect dimensional deviations, shape errors, and other issues in products, thereby ensuring product quality and consistency. With the advancement of automation technology, an increasing number of dimensional inspection devices are being integrated into automated measurement systems. These systems can automatically complete measurement tasks and transmit the measurement results in real time to a computer or control system for analysis and processing. Automated measurement systems greatly improve measurement efficiency and accuracy and reduce the error rate of manual operations. For example, CCD dimensional inspection equipment obtains dimensional information of objects through a non-contact method, avoiding damage to the object caused by contact measurement. CCD dimensional inspection equipment uses a CCD camera to capture an image of the object and obtains dimensional information through image processing software.

[0003] At present, in order to quickly realize size detection, a turntable is generally set on the CCD size detection equipment to position and move the product. A CCD camera and other detection mechanisms are set on the outside of the turntable. As the turntable rotates, the product is photographed and inspected. In the existing technology, when inspecting products with structures such as screws and bolts, they are often positioned by physical clamping and then inspected. The fixing method is cumbersome and the positioning accuracy is poor. In addition, if there are some impurities attached to the product, it will affect the photographic inspection.

[0004] Therefore, it is necessary to propose a size detection equipment with a workpiece positioning turntable to solve the above problems. Utility Model Content

[0027] In order to realize the rotation of the product, a fixed base 8 is provided on the side of the blowing rack 5 close to the turntable 1, and a vertically arranged first rotating shaft 9 is rotatably connected to the fixed base 8. A second gear 10 is fixedly provided on the top of the first rotating shaft 9, and a second motor 7 for driving the first rotating shaft 9 to rotate is provided at the bottom of the fixed base 8.
