Description

Technical Field

[0001] The utility model relates to the technical field of machine tool manufacturing, in particular to a scraping and grinding detection device for a numerical control machine tool. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, various control signals are sent by the CNC device to control the movement of the machine tool, and automatically process the parts according to the shape and size required by the drawing. CNC machine tools have better solved the problem of complex, precise, small batch, and multi-variety parts processing. They are flexible and efficient automated machine tools, representing the development direction of modern machine tool control technology. They are a typical mechatronics product. When processing CNC machine tools, they are mainly processed by equipment, especially high-precision equipment such as slide rails, and processed by ordinary turning, grinding and other equipment. However, the processing of actual equipment does not achieve enough precision, and operators are required to perform manual grinding.

[0003] After searching, a scraping and grinding detection device for CNC machine tools was disclosed in the Chinese Utility Model Patent Publication No. CN207866181U, wherein the gripper comprises a first gripper and a second gripper, both of which are U-shaped structures, and both of which comprise a gripping plate and connecting plates arranged at both ends of the gripping plate, and the connecting plates of the first gripper and the second gripper are connected to the bottom surface of the detection plate. When in use, the top surface of the detection plate is directly moved on the surface of the product, and the coating layer is used to rub the surface of the product, so that the unevenness on the surface of the product can be detected. However, this method mainly relies on workers grasping the gripper and pushing the detection plate for detection, but human power push is likely to cause uneven force, affecting the detection effect, and if the impurities on the detection plate are not cleaned before detection, it will also affect the detection effect. Therefore, a scraping and grinding detection device that can ensure the detection effect as much as possible is needed. Utility Model Content
