Before processing, the aluminum plates must first be fixed to prevent the aluminum plates from shifting during the cutting process and affecting production quality. The existing fixing devices are complicated to operate and cannot be clamped and fixed quickly by humans, which affects production efficiency. In addition, due to the different thicknesses of each aluminum plate, the clamping device cannot fix aluminum plates of different thicknesses, which has certain limitations. Utility Model Content

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0023] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a thin-walled aluminum plate clamping device, including a base 1, a first fixing frame 2 and a second fixing frame 3 are fixedly installed on the top of the base 1, a column 21 is fixedly installed on one side of the first fixing frame 2, a spring 22 is movably installed on the surface of the column 21, a crank 23 is movably installed on the top of the first fixing frame 2, a clamp 4 is provided on the other side of the first fixing frame 2, a connecting plate 41 is fixedly installed on one end of the clamp 4, a limiting plate 42 is fixedly installed on one end of the connecting plate 41, an opening 421 is opened inside the limiting plate 42, and the surface of the column 21 is located at the opening 42 1, a connecting seat 43 is fixedly installed at the bottom of the clamp 4, and a clamp block 5 is movably installed at the top of the clamp 4. The bottom of the crank 23 is fixedly connected with a screw rod 24, and the bottom end of the screw rod 24 is movably connected to the bottom end of the inner wall of the first fixed frame 2. A movable block 25 is provided inside the first fixed frame 2, and one end of the movable block 25 is movably connected to a connecting rod 26. The inner wall of the movable block 25 is threadedly connected to the surface of the screw rod 24, and the top end of the connecting rod 26 is movably connected to the inner wall of the connecting seat 43. The first fixed frame 2 and the second fixed frame 3 have the same structure, and the surface of the connecting plate 41 is slidably connected to the inner wall of the first fixed frame 2.

[0024] In this embodiment, by turning the crank 23, the crank 23 drives the screw 24 to rotate, so that the movable block 25 moves up and down on its surface. When the movable block 25 moves upward, the connecting rod 26 rotates with the movable block 25 as the center, and the top end of the connecting rod 26 pushes the clamp 4 to the right. At the same time, the connecting plate 41 drives the limit plate 42 to approach the first fixed frame 2. The limit plate 42 slides on the surface of the column 21 to squeeze the spring 22 to deform it under force. Reversing the crank 23 can move the clamp 4 close to one end of the first fixed frame 2, and place the aluminum plate on the top of the clamp 4. By adjusting the position of the clamp 4, it is convenient to clamp and fix the aluminum plate at a horizontal angle. Example

[0025] like Figure 1-Figure 5 As shown, the surface of the clamping block 5 is movably connected to the inner wall of the clamp 4, and a clamping block 44 is fixedly installed on the inner wall of the clamp 4. The clamping block 44 is triangular in shape, a turning handle 51 is movably installed on the top of the clamping block 5, and a disc 52 is fixedly connected to the bottom end of the turning handle 51, and two extrusion blocks 53 are fixedly installed on the surface of the disc 52, and a first movable block 6 and a second movable block 7 are movably installed on the inner wall of the clamping block 5. The first movable block 6 and the second movable block 7 have the same structure but opposite directions, a clamping block 61 is fixedly installed on the outer end of the first movable block 6, and a spring 62 is fixedly connected to the inner end of the first movable block 6, and a fixed block 63 is fixedly installed on the surface of the first movable block 6, one end of the spring 62 is fixedly connected to the inner end of the second movable block 7, and one side of the fixed block 63 is tightly fitted with the surface of the disc 52.

[0026] In this embodiment, when the aluminum plate is fixed by the clamp 4, by pressing the clamp 5 downward, the second clamping block 61 is squeezed by the first clamping block 44 and shrinks into the inside of the clamp 5, and the second clamping block 61 is rebounded by the second spring 62 and engages with the first clamping block 44, so that the clamp 5 cannot move upward, and the vertical angle of the aluminum plate is limited and fixed. By turning the handle 51, the disc 52 and the extrusion block 53 are driven to rotate, and the extrusion block 53 rotates to squeeze the fixed block 63, so that the first movable block 6 and the second movable block 7 shrink into the inside of the clamp 5 at the same time. At the same time, the second spring 62 is deformed by force. When the first movable block 6 and the second movable block 7 shrink to the inside of the clamp 5, the clamp 5 can be lifted upward, which is convenient for limiting and fixing aluminum plates of different thicknesses.

[0027] The working principle of this embodiment is as follows: the aluminum plate is placed on the top of the clamp 4, and the screw 24 is rotated by turning the crank 23. The movable block 25 moves upward, while the top of the connecting rod 26 pushes the clamp 4 to the right. At the same time, the connecting plate 41 drives the limiting plate 42 to approach the first fixed frame 2, and the limiting plate 42 slides on the surface of the column 21 to squeeze the spring 1 22 to make it deformed by force. By adjusting the position of the clamp 4, the horizontal angle of the aluminum plate is clamped and fixed, and the clamp block 5 is pressed downward to move. The clamp block 5 is squeezed by the clamp block 1 44 and shrinks into the inside of the clamp block 5. The clamp block 5 is engaged with the clamp block 1 44 through the spring 22, so that the clamp block 5 cannot move upward, and the turning handle 51 is turned to drive the disc 52 and the extruding block 53 to rotate. The extruding block 53 rotates to squeeze the fixed block 63, so that the first movable block 6 and the second movable block 7 shrink into the inside of the clamp block 5 at the same time, and the clamp block 2 61 is separated from the clamp block 1 44, and the clamp block 5 can be lifted upward, which is convenient for limiting and fixing aluminum plates of different thicknesses.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
