Description

Technical Field

[0001] This utility model relates to the field of grinding machines, specifically a surface grinding machine for high-precision aluminum ruler processing. Background Technology

[0002] Magnesium-aluminum alloy knife-edge ruler, also known as magnesium-aluminum flat ruler or aluminum-magnesium flat ruler, is made of magnesium-aluminum alloy and features lightweight, deformation resistance, and corrosion resistance. The working surface is precision ground and scraped, with straightness error controlled within 1μm and surface roughness reaching Ra0.025μm. During processing, the surface of the aluminum alloy needs to be polished.

[0003] For example, patent CN209887396U discloses a flat grinding machine with a dust removal device, belonging to the field of grinding machine technology. It includes a frame, a worktable connected to the frame, a grinding wheel arranged on the frame above the worktable, the grinding wheel being arranged perpendicular to the worktable, a cover connected to the frame, the worktable being disposed inside the cover and connected to the cover, a drive assembly arranged on the side of the cover away from the frame, a cleaning brush connected to the drive assembly, the bristles of the cleaning brush abutting against the surface of the worktable, and the cleaning brush being driven by the drive assembly to move along the length of the worktable.

[0004] The aforementioned patent has the effect of automatically cleaning the dust adhering to the worktable surface after the workpiece is polished and the grinding wheel is lifted, thus reducing the workload of the workers; however, the disadvantage of the aforementioned patent is that it lacks protection, and if the grinding wheel feeds too much at one time, the workpiece may be blown away by the grinding wheel, which can easily lead to an accident.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0040] The third stepper motor 505 can drive the third moving seat 502 to move up and down along the third guide rail 501 via the third ball screw 503.

[0041] A grinding motor 601 is fixedly installed on the top of the third movable seat 502. The output shaft of the grinding motor 601 passes through the third movable seat 502 and is fixedly connected to a grinding wheel 6.

[0042] In this scheme, the protective device 7 includes two protective side plates 701, which are located on the left and right sides of the horizontal feeding device 2 respectively.

[0048] If the workpiece detaches from the vise 212 at this time, it will first hit the side wall of the mounting slot. The workpiece will rebound after hitting the side wall of the mounting slot and then hit the protective side plate 701 or the protective horizontal plate 702. At this time, the kinetic energy of the workpiece is absorbed and the speed of the workpiece is greatly reduced, which can effectively reduce the occurrence of accidents that injure workers.
