Technical Field

The invention relates to the technical field of permanent magnet fixing, in particular to a workpiece electric permanent magnet fixing device of a numerical control machine tool.

Background

When drilling a flat plate part, a drilling reference needs to be determined and is fixed. In the prior drilling production of a numerical control plane drilling machine, a flat plate is fixed in a mode of clamping the flat plate by a hydraulic clamp, and a bearing surface in a clamp mouth is used as a positioning reference. When the flat plate is clamped, the position of the hydraulic clamp on the positioning guide rail is adjusted according to the size of the flat plate so as to realize positioning and clamping of the flat plate. Before clamping the flat plate, the flat plate is required to be tightly attached to the clamp positioning surface in the X direction and the Y direction, and the flat plate is inconvenient to check whether the flat plate positioning surface is overlapped with the positioning reference or not because the positioning surface is arranged on the inner side of the jaw and the flat plate is clamped by at least two clamps in the X direction and the Y direction.

Since the adjustment of the position of the flat plate needs to be manually performed, there is a possibility of safety accidents. Under the influence of a clamping mode of the hydraulic clamp, workpieces with irregular shapes cannot be machined on the plane drilling machine, only one workpiece can be clamped at a time, and the machining efficiency is low; a large amount of time is spent on correction action, so that the processing efficiency is further reduced; in addition, the clamping edge of the workpiece is easy to damage, and unnecessary damage is caused.
