technical field

The application belongs to the technical field of machining, and specifically discloses a numerically controlled machine tool with precise workpiece positioning.

Background technique

The stability of workpiece positioning is an important factor affecting the machining accuracy of machine tools. Existing CNC machine tools that use a press bar to fix the workpiece generally only have one press bar, and it is impossible to detect whether the press bar matches the size of the part. Although the operation is simple, it affects the finish of the part. If the press bar When pressing the material, if it does not match the size of the part, it will easily lead to the loosening of the part or the inability to completely compress the part to be processed. When milling the part, it is easy for the milling cutter to not pass the milling surface of the part to be processed accurately, resulting in errors, such as parts The size of the processed surface is inconsistent, which is an unnecessary loss.

Compared with the prior art, the utility model has beneficial technical effects: it is equipped with a pressure rod detection device, and the detection device includes a pressure rod accommodation box. The binder rod storage box has multiple binder rod placement positions, and can be equipped with multiple specifications of binder rods at the same time. The appropriate binder rod can be selected according to the size of the workpiece. The size of the workpiece is corresponding, which is beneficial for the pressing rod to press the workpiece more firmly. Generally, there is only one pressing rod, and the machine tool that cannot detect whether the pressing rod and the size of the part match each other is easy to be caused by pressure when milling the part. The discrepancy between the size of the material rod and the workpiece leads to loosening and displacement of the workpiece on the workbench, and the inaccurate milling surface. The utility model improves the fit between the pressure material rod and the workpiece by being equipped with different specifications of the pressure material rod. By setting the pressure rod detection device, it can automatically detect whether each pressure rod is placed in its corresponding pressure rod position, reducing the number of workers who do not place the pressure rod in the corresponding position when replacing the workpiece with the pressure material. The bit error rate is improved, the work efficiency is improved, and the machining accuracy of the machine tool to the workpiece is improved.
