Description

Technical Field

[0001] The present application relates to the field of drilling processing of metal plates, and in particular to a protection mechanism for drilling processing of metal plates. Background Art

[0002] Metal plates are a common type of metal product, usually made from metal materials through processing techniques such as rolling, drawing, or forging. Drilling processing of metal plates is a common operation for hole processing on metal plates, usually using equipment such as drill presses and drill bits. This processing process can be used to manufacture metal structural parts, mechanical parts, automotive parts, etc., and is widely applied in the fields of engineering manufacturing and processing.

[0003] During the processing, generally, the drilling equipment acts on the metal plate. However, during the drilling process of the metal plate, a certain amount of metal debris will be generated, and the debris will scatter into the surrounding environment along with the rotation of the drill bit, thus having a certain impact on the surrounding operators. At the same time, the scattered and splashing workpiece debris is time-consuming and laborious to clean, increasing the labor intensity during cleaning.

[0004] Regarding the above related technologies, the inventor believes that there are defects in the generation of scattered and splashing metal debris during the drilling processing of metal plates. Therefore, a protection mechanism for drilling processing of metal plates is proposed to solve the above problems. Utility Model Content

An outer sliding sleeve is movably installed on the outer surface of the support plate. A fixed frame is welded on the upper surface of the outer sliding sleeve. A movable plate is movably installed on the outer surface of the fixed frame. A through hole is formed through the middle of the top end of the movable plate. A fixed sleeve is fixedly connected to the outer surface of the bottom end of the movable plate near the through hole. Fixed frames are welded on both side edges of the bottom end of the movable plate near the fixed sleeve. A protection component is also provided between the fixed sleeve and the fixed frames.

[0008] Preferably, the protection component includes a movable baffle. The movable baffle is movably installed between the fixed sleeve and the fixed frames. A limit card plate is fixedly installed on the upper surface of the movable baffle. Springs are symmetrically installed between the upper surface of the limit card plate and the bottom surface of the movable plate.

[0009] Preferably, limiting screws are rotatably installed on both side edges of the top end of the movable plate. One side of the top of the limiting screw extends above the fixing frame, and the limiting screw is threadedly connected to the upper surface of the fixing frame.

[0010] Preferably, square holes are symmetrically and penetratingly formed on both side edges of the top end of the movable plate. One side of the outer surface of the fixing frame is located inside the square hole, and the fixing frame and the movable plate are mutually fitted.

[0011] Preferably, grooves are symmetrically formed on one side of the inner wall of the fixing frame. The spring is located in the groove between the fixing sleeve and the fixing frame, and the spring and the fixing frame are mutually coupled.
