Detailed implementation manners

[0014] Now, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0015] As Figure 1 shown: A rapid clamping device for aluminum profile processing includes a base 1.

[0016] As Figures 1 - 6 shown: Combined with the above content, in order to improve the stability of the aluminum profile during the process, it further includes a clamping assembly 2 installed on the surface of the base 1; The clamping assembly 2 includes moving plates 21 symmetrically arranged on the surface of the base 1. Opposite surfaces of the two moving plates 21 are provided with clamping blocks 25. One side of the clamping block 25 is provided with a rotating flexible clamping block 1 27. The rotating flexible clamping block 1 27 is rotatably connected in a first arc groove 26 formed on the surface of the clamping block 25. One side of the rotating flexible clamping block 1 27 away from the clamping block 25 is provided with a rotating flexible clamping block 2 29. The rotating flexible clamping block 2 29 is rotatably connected in a second arc groove 28 formed on the surface of the rotating flexible clamping block 1 27.

[0017] In this implementation: The rotatable flexible clamp block 1-27 and the rotatable flexible clamp block 2-29 can fit the surface of the aluminum profile from different angles. This clamp block design with multi-dimensional fitting can effectively prevent the aluminum profile from shaking or shifting during the processing, greatly improving the processing stability, ensuring the dimensional accuracy of the product. When fixing aluminum profiles of different shapes, it can flexibly adjust the position and angle, closely fit, solve the problem that traditional clamps are difficult to clamp aluminum profiles with complex shapes, broaden the applicable range of the positioning clamp, and further improve the stability when processing aluminum profiles of different shapes. It does not require frequent replacement of the chuck, reducing production costs.

[0018] In an alternative embodiment: A double-headed cylinder 2-10 is installed on the bottom surface of the base 1. Connecting plates 2-11 are installed at both ends of the double-headed cylinder 2-10. Diagonal rods 2-12 are symmetrically installed on one side of the connecting plate 2-11. A fixed block 2-2 is slidably connected in a strip groove opened on the surface of the base 1. The fixed block 2-2 is fixedly installed on the bottom surface of the moving plate 2-1. The diagonal rod 2-12 is slidably connected in an inclined hole opened on the surface of the fixed block 2-2.

[0019] In this implementation: When it is necessary to adjust the distance between the moving plates 2-1 to adapt to aluminum profiles of different widths, the double-headed cylinder 2-10 is activated. The connecting plates 2-11 at both ends thereof will move with the expansion and contraction of the cylinder. Since the diagonal rods 2-12 are symmetrically installed on one side of the connecting plate 2-11 and are slidably connected in the inclined holes on the surface of the fixed block 2-2, and the fixed block 2-2 is fixed to the bottom surface of the moving plate 2-1, the movement of the diagonal rod 2-12 will push the fixed block 2-2, thereby driving the moving plate 2-1 to slide smoothly in the strip groove on the surface of the base 1.

[0020] In an alternative embodiment: A guide block 2-4 is fixedly installed on one side of the clamp block 2-5. A guide rail 2-3 is slidably connected to the surface of the guide block 2-4. The guide rail 2-3 is fixedly installed on the inner side surface of the moving plate 2-1.

[0021] In this implementation: According to the approximate size of the aluminum profile, slide the guide block 2-4 on the surface of the guide rail 2-3. After changing the position of the clamp block 2-5, the T-shaped limit insertion rod 2-14 can be inserted into the corresponding limit insertion hole 2-16. The provided spring 2-15 can ensure that one end of the T-shaped limit insertion rod 2-14 can be stably inserted into the corresponding limit insertion hole 2-16, improving the positioning accuracy. By precisely adjusting the position of the support and clamping, the workpiece can be accurately fixed at the ideal processing position.

[0022] In an alternative embodiment: An L-shaped fixing plate 2-13 on the surface of the guide block 2-4. A T-shaped limit insertion rod 2-14 is slidably connected in a through hole opened on the surface of the L-shaped fixing plate 2-13. One end of the T-shaped limit insertion rod 2-14 penetrates through the L-shaped fixing plate 2-13 and is inserted into a limit insertion hole 2-16 opened on the side wall of the moving plate 2-1.

[0023] In this implementation: When it is necessary to adjust the position of the clamping block 25 to adapt to different aluminum profiles, the operator only needs to pull out the T-shaped limit insertion rod 214, and then the clamping block 25 can be freely moved. After the clamping block 25 is adjusted to the appropriate position, insert the T-shaped limit insertion rod 214 again for fixation. This operation method is simple and direct, greatly saving the time required to adjust the position of the clamping block, improving the adaptability of the positioning fixture to different aluminum profiles and the operation efficiency, and is particularly suitable for production scenarios that require frequent replacement of the processed aluminum profile specifications.

[0024] Furthermore: Combined with the above content, in order to further improve the stability of fixation, it further includes an auxiliary counter-fixing component 3 symmetrically installed on the surface of the moving plate 21. The auxiliary counter-fixing component 3 includes a mounting plate 32 fixedly installed on one side surface of the moving plate 21. A lead screw 33 is rotatably connected to the surface of the mounting plate 32. A pressure plate 37 is threadedly connected to the surface of the lead screw 33. An inwardly concave placement plate 31 is installed at the center position of the surface of the base 1.

[0025] In this implementation: During the milling process of the aluminum profile, the cutting force is likely to cause the profile to displace. The pressure plate 37 of the auxiliary counter-fixing component 3 can apply pressure to the side of the aluminum profile, forming a multi-directional clamping with the clamping component 2, which can effectively prevent the profile from shaking and ensure the machining accuracy.

[0026] In an alternative embodiment: A gear 34 is installed at one end of the lead screw 33 passing through the mounting plate 32. A toothed plate 35 is installed in the strip-shaped groove opened on the surface of the base 1. The gear 34 meshes on the surface of the toothed plate 35.

[0027] In this implementation: As the moving plate 21 moves, the lead screw 33 rotatably arranged on one side of the moving plate 21 can follow the movement. Since a gear 34 is installed at one end of the lead screw 33 passing through the mounting plate 32, and the gear 34 meshes on the surface of the toothed plate 35, and the toothed plate 35 is installed in the strip-shaped groove opened on the surface of the base 1, when the lead screw 33 follows, the gear 34 will roll along the toothed plate 35, driving the lead screw 33 to rotate. As the lead screw 33 moves, the connecting piece 36 threadedly connected to the surface of the lead screw 33 will drive the pressure plate 37 to gradually approach the aluminum profile, and counter-fix the aluminum profile again, further enhancing the stability of the aluminum profile during the processing.

[0028] The working principle and usage process of the present invention: First, firmly install the base 1 on the workbench of the processing equipment. According to the approximate size of the aluminum profile, slide the guide block 24 on the surface of the guide rail 23. After changing the position of the clamping block 25, the T-shaped limit insertion rod 214 can be inserted into the corresponding limit insertion hole 216. The provided spring 215 can ensure that one end of the T-shaped limit insertion rod 214 can be stably inserted into the corresponding limit insertion hole 216, improving the positioning accuracy. By precisely adjusting the position of the support and clamping, the workpiece can be accurately fixed at the ideal processing position; Start the double-headed cylinder 210. The connecting plates 211 at both ends of the double-headed cylinder 210 drive the inclined rod 212 to move. Since the inclined rod 212 is slidably connected in the inclined hole formed on the surface of the fixed block 22, and the fixed block 22 is fixed to the bottom surface of the moving plate 21, the movement of the inclined rod 212 will push the moving plate 21 to move horizontally along the strip groove on the surface of the base 1, adjusting the two moving plates 21 to an appropriate distance to adapt to the width of the aluminum profile. Subsequently, place the aluminum profile on the concave placement plate 31. The shape of the concave placement plate 31 can be designed according to the bottom shape of common aluminum profiles, playing a role in preliminary positioning to ensure that the position of the aluminum profile on the horizontal plane is relatively fixed; Continue to control the double-headed cylinder 210 to drive the two moving plates 21 to move relative to each other, and then push the clamping block 25 to approach the aluminum profile. When the clamping block 25 approaches the aluminum profile, the rotating flexible clamping block one 27 starts to function. Since the rotating flexible clamping block one 27 is rotatably connected in the first arc groove 26 formed on the surface of the clamping block 25, it can be adaptively adjusted according to the surface shape of the aluminum profile and fit the surface of the aluminum profile. Then, rotate the flexible clamping block two 29, which is rotatably connected in the second arc groove 28 formed on the surface of the rotating flexible clamping block one 27, to further fit the complex contour of the aluminum profile and achieve tight clamping of the aluminum profile. The combination of the two rotating flexible clamping blocks can fit the surface of the aluminum profile from multiple angles, solving the problem that traditional fixtures are difficult to clamp aluminum profiles with complex shapes, broadening the application range of the positioning fixture. In actual processing, operators do not need to spend a lot of time adjusting the fixture to adapt to different-shaped aluminum profiles. The adaptive characteristics of the rotating flexible clamping blocks enable automatic adaptation when replacing aluminum profiles of different specifications, improving production efficiency and reducing processing costs; As the moving plate 21 moves, the lead screw 33 rotatably arranged on one side of the moving plate 21 can follow the movement. Since a gear 34 is installed at one end of the lead screw 33 passing through the mounting plate 32, and the gear 34 meshes with the surface of the toothed plate 35, and the toothed plate 35 is installed in the strip groove formed on the surface of the base 1, when the lead screw 33 follows, the gear 34 will roll along the toothed plate 35, driving the lead screw 33 to rotate. As the lead screw 33 moves, the connecting piece 36 threadedly connected to the surface of the lead screw 33 will drive the pressing plate 37 to gradually approach the aluminum profile, further fixing the aluminum profile and further enhancing the stability of the aluminum profile during processing.

[0029] What is described in the above specification is only the specific implementation manner of the present invention. Various examples do not constitute a limitation to the essence of the present invention. Those of ordinary skill in the art can make modifications or deformations to the previously described specific implementation manner after reading the specification without departing from the essence and scope of the invention.
