Description

Technical Field

[0001] The utility model belongs to the technical field of CNC machining equipment, and particularly relates to an automatic positioning and correction mechanism for CNC machining equipment. Background Technique

[0002] CNC is the abbreviation of Computerized Numerical Control Machine Tool, which is an automated machine tool controlled by a program. The numerical control machine tool can directly process any product and part automatically according to the program prepared by technicians in advance. During the numerical control machining process, it is necessary to position the product to be machined.

[0003] A Chinese patent application with the publication number CN214868797U discloses a CNC machining automatic positioning device, including a base, fastening screws and support columns. The fastening screws are installed on the surface of the base, the support columns are fixedly connected to the upper surface of the base, a protective device is fixedly connected to the upper surface of the support columns, and a precise device is installed inside the protective device. Through the protective device composed of a working plate, a groove, a fixing block, a protective plate and a fixing screw, during the working process, the product to be machined can be protected by the cooperation of the working plate, the protective plate and the fixing screw to prevent external factors from affecting the machining.

[0004] Although the product can be positioned more precisely and the work efficiency can be improved through the cooperation of fixing screws, electric telescopic rods, connecting plates, positioning plates and positioning blocks, this patent does not have an automatic correction function. After the workpiece is positioned, it may be inclined and not horizontal, resulting in the uneven cutting amount of the tool during the CNC machining process, affecting the service life of the tool, and reducing the machining accuracy of the workpiece. Therefore, we provide an automatic positioning and correction mechanism for CNC machining equipment to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an automatic positioning and correction mechanism for CNC machining equipment. Through the combined setting of a correction component and a positioning component, it solves the problem that the existing automatic positioning and correction mechanism for CNC machining equipment does not have an automatic correction function and cannot automatically adjust the level of the workpiece, affecting the machining accuracy of the workpiece.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is an automatic positioning and correction mechanism for CNC machining equipment, including a base, a correction component and a positioning component.
