Description

Technical Field

[0001] The utility model relates to the technical field of automatic turning devices for numerical control engraving machines, in particular to an automatic turning device for numerical control engraving machines. Background Art

[0002] CNC machining refers to a process method for machining parts on CNC machine tools. The process procedures of CNC machine tool machining are generally consistent with those of traditional machine tool machining, but there have also been significant changes. It is a mechanical machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve problems such as a wide variety of parts, small batches, complex shapes, and high precision, and to achieve efficient and automated machining. CNC machine tools use group technology to process parts, which can expand batches, reduce programming volume, and improve economic benefits. In existing CNC machining, when double-sided machining of materials is performed, the other side is mostly processed by manual flipping of the workpiece, which has low flipping efficiency and increases the workload of personnel.

[0003] After searching, it was found that a CNC hydraulic automatic flipping device was disclosed in the Chinese patent with authorization announcement 201310224842.0, which includes a flipping plate (1), a support plate (2), a power cylinder (3), a positioning block (4), a base plate (5), and a rotating shaft (6). The base plate (5) is symmetrically provided with support plates (2) at both ends, and a rotating shaft (6) is horizontally provided between the support plates (2). The flipping plate (1) is installed on the rotating shaft (6), and a positioning block (4) is provided on the support plate (2) on one side of the flipping plate (1), and a power cylinder (3) is installed on one side of the support plate (2). It automatically performs secondary positioning on the processing process. It is realized that a 3-axis machining center replaces a 4-axis or 5-axis machining center to complete the processing of parts with complex technical requirements, thereby reducing the cost of part processing and improving mechanical processing efficiency.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] The CNC hydraulic automatic flipping device uses a flipping plate to flip as a whole. If the material is not fixed during flipping, the material will fall off when flipping at a certain angle, and after flipping, the material cannot be processed a second time because the flipping plate is placed on top. Utility Model Content
