Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a machine tool with an automatic part turning function. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It 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, input them into the CNC device through information carriers, and after calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing.

[0003] In the process of mechanical processing, it is often necessary to process multiple surfaces or different parts of a part, while the existing CNC machine tools can only process a single side of the workpiece when processing the workpiece, and usually require manual U-turn or re-clamping and positioning, and then put it into the machine tool for further processing, and the efficiency of manual operation is low, which will significantly increase the processing cycle of the part, which is not conducive to large-scale production, resulting in reduced workpiece production efficiency, and it is difficult to ensure that the clamping accuracy is completely consistent each time during manual clamping and U-turning, which is easy to cause clamping errors, resulting in reduced workpiece processing accuracy, and manual operation labor intensity is high, and in the frequent clamping process, it is easy to cause injuries to operators. For example, patent CN109648379B discloses a machine tool with a workpiece U-turn function, including a bed, a spindle is installed at the head end of the bed, a chuck is installed at the head end of the spindle, and a U-turn device, which includes a material return drive mechanism installed at the head end of the bed, a material ejection drive mechanism installed at the tail end of the bed, and a material receiving device, a material ejection rod and a lifting and rotating device located between the material return drive mechanism and the material ejection drive mechanism. By adopting the above technical scheme, through the setting of the material receiving device and the rotating mechanism, the workpiece can be received and turned around after being detached from the chuck, thereby realizing the turning process of the workpiece. However, the above technical scheme turns the workpiece around after being detached from the chuck. When the workpiece is loaded into the three-jaw chuck again, there is a probability that the position of the workpiece and the three-jaw chuck will be offset relative to before the turning, causing the positioning reference of the workpiece to shift, making it difficult to ensure that the clamping accuracy is completely consistent each time, which is easy to cause clamping errors, resulting in reduced workpiece processing accuracy.
