Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled machine tools, in particular to a bridge plate for numerically controlled machine tools. Background Art

[0002] A bridge plate is a vertical milling machine, which means that the workpiece is placed and processed in a vertical direction during the processing, which makes the bridge plate CNC machine suitable for vertical milling, drilling and cutting operations on the workpiece. The bridge plate is a brand and model, but it is also often used as a general term in the industry to refer to vertical CNC milling machines.

[0003] For example, a bridge plate for a CNC machine tool disclosed in the authorization announcement number CN207372686U includes a bed and columns, the columns include a left column and a right column, the left column and the right column are connected through a bridge plate, and the bridge plate is provided with a clamp, a dust removal device and a shielding plate. After adopting the above technical solution, the beneficial effect of the utility model is that the dust removal device collects the waste chips at the end away from the staff into the collection tank through the electric slider, reducing the cleaning dead angle.

[0004] The above device has a simple structure and reasonable design, can meet the needs of users, and has great promotion value;

[0005] However, the above patent has the following shortcomings:

[0006] The above-mentioned bridge plate for CNC machine tools collects the waste chips at the end away from the staff into the collection trough through an electric slider to reduce the cleaning dead corners, wherein the brush of the connecting arm drives the waste chips to move and enter the collection trough. However, since the brush can only clean the part of the bridge plate close to the inner side, the debris generated when the workpiece is processed will splash around the bridge plate, so the remaining debris needs to be manually cleaned later.
