Description

Technical Field

[0001] The utility model relates to the technical field of material processing, and more specifically to a self-cleaning cleaning device for a vertical milling machine. Background Art

[0002] Compared with horizontal milling machines, the main difference between vertical milling machines is that the spindle is arranged vertically. In addition to the different spindle arrangements, the workbench can be raised and lowered. The milling cutter used in vertical milling machines is relatively flexible and has a wider range of applications. You can use end mills, machine-clamped cutter discs, drill bits, etc. You can mill keyways, mill planes, bore holes, etc. Horizontal milling machines can also use the above tools, but they are not as convenient as vertical milling machines. The main reason is that you can use a hanger to enhance the strength of the tool (mainly three-face milling cutters, sheet milling cutters, etc.).

[0003] During the process of machining workpieces by a gantry milling machine, a large amount of workpiece waste will be generated by the milling head and the milling workpiece. The workpiece waste is accumulated on the workbench and the fixed plate, or falls to the ground, affecting the working environment and even the machining quality. Usually, the staff needs to manually clean the workpiece waste. The existing patent is a waste recovery device for a gantry milling machine. The patent authorization number is CN212665575U, which can automatically collect the waste generated during the operation of the gantry milling machine, thereby improving the work efficiency of the staff.

[0004] However, in patent authorization number CN212665575U, the moving block moves back and forth along the length extension direction of the fixed plate, driving the adjusting rod, the electric cylinder and the cleaning brush to move back and forth along the length direction of the fixed plate, thereby cleaning the bearing surface of the fixed plate. Since the cleaning brush needs to be pushed back and forth during the cleaning process, it is impossible to fully cover the waste chips on the fixed plate during the movement, affecting the cleaning efficiency. Therefore, we propose a self-cleaning cleaning device for a vertical milling machine to solve the above-mentioned problems. Utility Model Content
