[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 5 As shown, an aluminum profile processing clamping device includes a lifting frame 2, a fixed plate 3 and a pressing plate 4. The fixed plate 3 is fixed on the lifting frame 2, and a plurality of sliding holes 31 are opened on the fixed plate 3. Each sliding hole 31 is slidably provided with a sliding rod 33. The side of the fixed plate 3 is opened with an inlet 32 ​​connected to the sliding hole 31. The lower end of each sliding rod 33 is fixed with a first rubber pressing block 331; both ends of the pressing plate 4 are connected to the side of the fixed plate 3 by adjusting bolts 41, and the adjusting bolts 41 can adjust the distance between the pressing plate 4 and the fixed plate 3. A plurality of second rubber pressing blocks 42 corresponding to the inlet 32 ​​are fixed on the pressing plate 4. The rubber pressing blocks extend into the inlet 32 ​​and can squeeze the sliding rod 33.

[0033] In the present application, the distance between the pressing plate 4 and the fixing plate 3 is adjusted by adjusting the bolt 41. After loosening the adjusting bolt 41, the position of the slide bar 33 can be adjusted, thereby adjusting the position of the first rubber pressing block 331 at the lower end of each slide bar 33 according to the specific shape of the aluminum profile. This enables the device to effectively press aluminum profiles of different shapes. After the position of the first rubber pressing block 331 is adjusted, the adjusting bolt 41 is tightened again to move the pressing plate 4 toward the slide bar 33, and the second rubber pressing block 42 is pressed tightly against the slide bar 33.

[0034] Due to the design of the adjustable slide bar 33 and the first rubber pressing block 331, the clamping device can adapt to aluminum profiles of different sizes and shapes, greatly improving its versatility and flexibility. The first rubber pressing block 331 provides a certain buffer and protection on the surface contacting the aluminum profile, avoiding possible damage to the aluminum surface caused by hard clamps.

[0035] Specifically, the outer surface of the slide bar 33 is configured as a rough surface, and the second rubber block can press the rough surface to limit the slide bar 33 from sliding.

[0036] The rough surface increases the friction between the slide bar 33 and the second rubber block, making it more difficult for the slide bar 33 to slide after being clamped, thereby effectively limiting the accidental movement of the slide bar 33 during processing and ensuring processing accuracy and stability. The rough surface exhibits better grip and non-slip properties in different working environments (such as wet or dusty environments), increasing the scope of application and environmental adaptability of the equipment.

[0037] Specifically, a plane portion 332 is provided on the slide rod 33 , and the rough surface is provided on the plane portion 332 , and the rough surface does not contact the inner wall of the slide hole 31 .

[0038] Since the rough surface does not contact the inner wall of the slide hole 31, the friction between the slide rod 33 and the slide hole 31 is reduced, thereby reducing wear and possible jamming, extending the service life of the device and reducing maintenance requirements. By arranging the rough surface on the flat portion 332, it can be ensured that when the second rubber block is squeezed, only the rough surface of the flat portion 332 contacts the rubber block, which can provide a more stable and concentrated clamping force, rather than the periphery of the entire slide rod 33.

[0039] Specifically, a guide strip 311 is provided on the inner wall of the sliding hole 31 , and a guide groove 333 is provided on the sliding rod 33 . The guide groove 333 cooperates with the guide strip 311 to limit the rotation of the sliding rod 33 .

[0040] The combination of the guide bar 311 and the guide groove 333 provides additional physical support, increases the structural stability of the entire system, and reduces vibration or deviation caused by the movement of the slide bar 33.

[0041] Specifically, a plurality of sliding holes 31 are distributed on the fixing plate 3 at equal intervals.

[0042] Specifically, it also includes a cylinder 7, a piston rod of the cylinder 7 is connected to the lifting frame 2, and the cylinder 7 drives the lifting frame 2 to move up and down.

[0043] The cylinder 7 can drive the lifting frame 2 to upgrade, thereby driving the first rubber pressing block 331 to be pressed tightly on the aluminum profile.

[0044] Specifically, a counterweight 5 is fixed to the upper end of the slide rod 33 , and the counterweight 5 can lean against the fixed plate 3 .

[0045] The function of the counterweight block 5 is to release the pressure of the second rubber pressure block 42 on the slide bar 33, so that the slide bar 33 can automatically slide down to the lowest position. When the slide bar 33 contacts the surface of the aluminum profile, it will be lifted upward, thereby forming a configuration that adapts to the height difference of the aluminum profile surface. This design effectively utilizes the gravity of the counterweight block 5 to ensure that the slide bar 33 can flexibly adapt to aluminum profiles of different heights, thereby improving the applicability and accuracy of the clamping device.

[0046] In another solution, a tension spring 6 is sleeved on the slide bar 33 , one end of the tension spring 6 is connected to the end of the slide bar 33 , and the other end is connected to the fixed plate 3 .

[0047] The main function of the tension spring 6 is to automatically pull the slide bar 33 back to the initial position or the preset position after the pressure of the second rubber pressure block 42 is released, so as to facilitate the reuse and quick replacement of the aluminum profile, thereby increasing the convenience and efficiency of the operation.

[0048] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0049] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
