Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy processing equipment, and particularly relates to a limiting structure of an aluminum alloy drilling device. Background Art

[0002] A punching machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It is also called a drilling machine, a punching machine, and a through-hole machine. It achieves the desired effect by drilling holes in precision parts. Aluminum alloy is a common industrial material, and its punching operation is a necessary process in the processing of aluminum alloy materials.

[0003] For example, a Chinese patent with publication number CN212857822U discloses an aluminum alloy profile punching processing device. The patent achieves the purpose of easy adjustment through the mutual use of a vertical plate, a first electric push rod, a top plate, a second electric push rod, a moving block, a through groove, a slider, a third electric push rod, a punching motor, a drill bit and a slide groove, which is convenient for the user to adjust the drill bit during the punching work, and facilitates the punching work at multiple positions. At the same time, the aluminum alloy profile can be clamped and limited, which not only improves the flexibility of the punching device, but also improves the punching accuracy of the aluminum alloy profile, while improving the surface processing quality of the aluminum alloy profile, making the appearance more beautiful and neat.

[0004] Although this patent improves the convenience of drilling adjustment, this patent still has structural deficiencies. For example, the second electric push rod is used to push the drilling machine to move and adjust the lateral position, and the third electric push rod is used to push the drilling machine to drill holes. In actual use, the drilling depth is convenient to adjust. At the same time, the first electric push plate and the limit plate are used to clamp the aluminum alloy. Although this makes the aluminum alloy stable, the position adjustment during drilling is not convenient enough. Utility Model Content
