[0002] Aluminum sheets, as a common lightweight metal material, are widely used in aerospace, building curtain walls, machinery manufacturing, electrical equipment, and many other fields. In practical applications, drilling is often required on aluminum sheets for installing screws, bolts, or connecting components. Drilling typically requires a drilling machine for rapid drilling. If the aluminum sheet is not reliably clamped during the drilling process, it can cause workpiece displacement, reducing machining accuracy, and may also lead to safety hazards due to drill bit slippage or workpiece bounce. Therefore, the clamps used with the drilling machine are crucial throughout the drilling operation.

Multiple rectangular slots 9 are sequentially opened on the outer wall of the connecting row 8. A positioning block 10 of the same size is detachably connected to one of the rectangular slots 9 of the connecting row 8. The cylinder 4 drives the clamping block 5 to extend and retract, passing through the opening of the top frame 1 and the clamping arm 2 to clamp the aluminum plate. The top of the top frame 1 is equipped with a connecting row 8, which can be selected to install positioning blocks 10 through multiple rectangular sockets 9 to assist in the quick positioning of aluminum plates of different specifications. The working port of the clamping arm 2 allows the drill bit to pass through to work on the aluminum plate. The top frame 1, clamping arm 2 and mounting plate 3 are connected in a modular way, which is convenient for disassembly, maintenance and upgrading.

[0018] In a further preferred embodiment, the outer wall of the connecting strip 8 has a threaded hole at the corresponding position of the rectangular socket 9, and the positioning block 10 is detachably locked to the threaded hole by the fastening bolt 11; The positioning block 10 is fixed by bolts, and its position can be adjusted and replaced. The structure is locked by threaded connection to prevent loosening during use, and the positioning position can be adjusted as needed.

[0019] More preferably, the positioning block 10 is L-shaped and fits into the rectangular socket 9 of the top frame 1 and the connecting row 8 respectively, and is used to abut against the rectangular aluminum plate to assist in positioning; L-shaped positioning blocks 10 form double-sided contact with the top frame 1 and the socket, clamping one corner of the aluminum plate. The geometric shape of the blocks is used to support the positioning boundary of the aluminum plate, accurately limiting the left and right positions of the aluminum plate and ensuring precise drilling operations.

[0020] In a further preferred embodiment, the clamping arm 2 is in the shape of an inverted L, with its top clamping end bent downwards to form a right angle, and the top of the clamping block 5 is provided with a reserved groove 7, which cooperate with each other to assist the drilling machine in processing aluminum plates; The inverted L-shaped structure causes the top of the bent clamping arm 2 to form a counter-pressure surface with the clamping block 5, providing a reliable clamping area, and the clamping block 5 does not obstruct the entry and exit of the drill bit of the drilling machine through its reserved groove 7.

[0021] More preferably, the bottom of the clamping block 5 is fixedly connected to two symmetrically arranged sliding rods 6, which are arranged along the movement direction of the clamping block 5 and are slidably connected to the mounting plate 3; The sliding rod 6 restricts the movement trajectory of the clamping block 5, keeping it in a stable straight up-and-down motion, reducing the swaying or tilting of the clamping block 5, and improving clamping stability.

[0023] A specific application of this embodiment is as follows: According to the size of the aluminum plate to be processed, a matching L-shaped positioning block 10 is installed at a suitable position on the connecting row 8 and locked with a fastening bolt 11 to achieve edge auxiliary limiting. The aluminum plate is slid between the top frame 1 and the clamping arm 2, so that one side of it is attached to the positioning block 10 and the other side is aligned with the clamping block 5 below the working opening. The cylinder 4 is activated, and the telescopic shaft drives the clamping block 5 to move upward through the working opening of the frame, forming an upper support and lower resistance clamp with the bent end of the clamping arm 2 to achieve stable fixation. Then, the aluminum plate can be drilled by a drilling machine. After the drilling is completed, the telescopic shaft of the cylinder 4 is retracted, and the clamping block 5 can be released to take out the processed aluminum plate.
