Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled milling machines, in particular to a positioning device for numerically controlled milling machines. Background Art

[0002] CNC milling machine is an automatic processing equipment developed on the basis of general milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machine can be divided into two categories: without tool magazine and with tool magazine. Among them, CNC milling machine with tool magazine is also called machining center. When the milling machine processes the workpiece, it is necessary to ensure the stability of the workpiece to avoid contact between the milling cutter and the workpiece. However, after the milling cutter applies pressure to the workpiece, it is easy to cause the position of the workpiece to shift, so it is necessary to study it.

[0003] Specifically, in a CNC milling machine, the workpiece is placed on the area to be processed and pressure is applied from the side to limit the bottom end of the workpiece. However, the shape of the workpiece to be processed is changeable, and sometimes it is necessary to process the inclined surface of the workpiece to be processed. When the clamping device drives the workpiece to be processed to adjust the angle, the workpiece to be processed is in an inclined state. If the milling cutter is used to directly process the inclined surface of the workpiece to be processed, the milling cutter directly applies pressure to the inclined surface of the workpiece to be processed, which will cause the instantaneous pressure on the workpiece to be processed to increase, making it easy to loosen when clamped, and then the position of the workpiece to be processed will be offset, affecting the cutting quality of the workpiece to be processed. For this reason, we propose a positioning device for a CNC milling machine. Utility Model Content
