[0024] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0025] like Figures 1-6As shown, a non-destructive clamping tool for profiles mainly includes a tool base 1, on which a fixed clamping mechanism and a sliding clamping mechanism are provided, through which the profiles can be clamped.

[0026] The fixed clamping mechanism includes a fixed mounting seat 21 fixedly mounted on one end of the tooling base 1 in the longitudinal direction, and the sliding clamping mechanism includes a sliding mounting seat 31 that can slide along the longitudinal direction of the tooling base 1 and a sliding drive device 32 for controlling the sliding of the sliding mounting seat 31.

[0027] Specifically, the upper surface of the tooling base 1 has a chute 11 extending along its length, with a fixed mounting seat 21 fixedly mounted at one end of the chute 11. In this embodiment, the fixed mounting seat 21 is attached to the tooling base 1 via a locking bolt, which is simple and reliable. A first slider 311 is integrally formed at the bottom of the sliding mounting seat 31, which slidably engages with the chute 11. Therefore, the sliding mounting seat 31 can slide along the length of the tooling base 1, thereby approaching or moving away from the fixed mounting seat 21, through the sliding engagement of the first slider 311 with the chute 11.

[0028] In this embodiment, the sliding drive device 32 includes a nut seat 321 and an adjusting screw 322 that forms a screw-nut kinematic pair with the nut seat 321. The nut seat 321 is located on the side of the sliding mounting seat 31 away from the fixed mounting seat 21, and the bottom of the nut seat 321 is integrally formed with a second slider 321a that slidably cooperates with the slide groove 11. The adjusting screw 322 extends horizontally, and one end of the adjusting screw 322 is rotatably connected to the side of the sliding mounting seat 31 away from the fixed mounting seat 21. The other end of the adjusting screw 322 is integrally formed with a bolt head 322a having a hexagonal prism structure. Therefore, by turning the bolt head 322a with a wrench, the adjusting screw 322 can simultaneously move axially while rotating, thereby precisely controlling the displacement of the sliding mounting seat 31, moving it closer to or away from the fixed mounting seat 21.

[0029] In order to reduce the length of the adjusting screw 322 and improve the reliability of the adjusting screw 322, in this embodiment, the upper surface of the tooling base 1 is provided with pairs of bolt holes 12 located in the slide groove 11, and the nut seat 321 can be locked in any pair of bolt holes 12 by the bolt 33, so that the nut seat 321 can be selectively locked in the corresponding bolt hole 12 according to different profiles.

[0030] Specifically, bolt mounting seats 321b are integrally formed on both sides of the nut seat 321. When the bolt through holes on the two bolt mounting seats 321b are located directly above the corresponding bolt holes 12, the bolt mounting seats 321b and the tooling base 1 can be locked into one by the bolts 33.

[0031] A floating clamping assembly with the same structure is installed on the side where the fixed mounting seat 21 and the sliding mounting seat 31 are close to each other. The floating clamping assembly consists of a first-level crescent-shaped rotating block 41, two second-level crescent-shaped rotating blocks 42, four third-level crescent-shaped rotating blocks 43 and eight fourth-level crescent-shaped rotating blocks 44.

[0032] Specifically, a first-level crescent-shaped rotating block 41 capable of rotating along the fixed mounting seat 21 and the sliding mounting seat 31 is installed on the side where they are close to each other, and two second-level crescent-shaped rotating blocks 42 capable of rotating along the first-level crescent-shaped rotating block 41 are installed on the side away from the corresponding fixed clamping mechanism or the sliding clamping mechanism, and two third-level crescent-shaped rotating blocks 43 capable of rotating along the second-level crescent-shaped rotating block 42 are installed on the side away from the corresponding first-level crescent-shaped rotating block 41, and two fourth-level crescent-shaped rotating blocks 44 capable of rotating along the third-level crescent-shaped rotating block 43 are installed on the side away from the corresponding second-level crescent-shaped rotating block 42. The first-level crescent-shaped rotating block 41, the second-level crescent-shaped rotating block 42, the third-level crescent-shaped rotating block 43 and the fourth-level crescent-shaped rotating block 44 are all crescent-shaped structures, which ensures the smoothness of rotation cooperation. At the same time, the side wall of the fourth-stage crescent-shaped rotating block 44 away from the corresponding third-stage crescent-shaped rotating block 43 is concave to form a clamping surface 441 with an arc structure, and the outer edges of both sides of the clamping surface 441 in the horizontal direction are rounded 442.

[0033] Therefore, the spacing between the fixed clamping mechanism and the sliding clamping mechanism can be adjusted, and eight four-stage crescent-shaped rotating blocks 44 with crescent-shaped structures and capable of rotation are provided in each of the two clamping directions, so as to adapt to profiles of different lengths and widths, ensuring reliable clamping; at the same time, the first-stage crescent-shaped rotating block 41, the second-stage crescent-shaped rotating block 42 and the third-stage crescent-shaped rotating block 43 installed step by step can also cooperate to perform adaptive rotation, so as to adapt to profiles of different cross-sectional shapes, further improving the reliability of clamping profiles with different cross-sectional structures; moreover, the outer edges on both sides of the clamping surface of the four-stage crescent-shaped rotating block 44 are chamfered to ensure damage-free clamping of the profile.

[0034] Further, see Figure 1 and Figure 2 The bottoms of both the fixed mounting block 21 and the sliding mounting block 31 are equipped with floating clamping assembly mounting plates 45 that extend toward each other.

The clamping surfaces 441 of each fourth-stage crescent-shaped rotating block 44 protrude beyond the corresponding floating clamping assembly mounting plate 45, preventing the clamped profile from interfering with the fixed mounting block 21 and the sliding mounting block 31.

[0035] See Figure 1-Figure 3 The sides of the fixed mounting seat 21 and the sliding mounting seat 31 that are close to each other are both recessed to form a first-level arc-shaped mating surface 46 that is adapted to the corresponding first-level crescent-shaped rotating block 41. The first-level arc-shaped mating surface 46 respectively forms an arc-shaped mating with the surface of the side of the corresponding first-level crescent-shaped rotating block 41 away from the second-level crescent-shaped rotating block 42. The first-level crescent-shaped rotating block 41 is respectively installed on the corresponding floating clamping assembly mounting plate 45 through the first rotating mating piece, ensuring the stability and reliability of the rotation of the first-level crescent-shaped rotating block 41.

[0036] Among them, the first rotating fitting is the first rotating shaft, and the first-stage crescent-shaped rotating block 41 can be rotatably mounted on the floating clamping assembly mounting plate 45 through the first rotating shaft, ensuring the stability and reliability of the rotation of the first-stage crescent-shaped rotating block 41.

[0037] See Figure 1 、 Figure 3 and Figure 4 The surface of one side of the first-level crescent-shaped rotating block 41 close to the second-level crescent-shaped rotating block 42 is recessed to form a second-level arc-shaped mating surface 411 that is adapted to the corresponding second-level crescent-shaped rotating block 42. The second-level arc-shaped mating surface 411 respectively forms an arc-shaped mating with the surface of the side of the corresponding second-level crescent-shaped rotating block 42 away from the third-level crescent-shaped rotating block 43. The second-level arc-shaped mating surface 411 is respectively installed on the corresponding first-level crescent-shaped rotating block 41 through the second rotating mating part, ensuring the stability and reliability of the rotation of the second-level crescent-shaped rotating block 42.

[0038] Among them, the second rotating matching part includes a first connecting block and a second rotating shaft. The first connecting block is arranged in the horizontal direction. One end of the first connecting block is rotatably connected to the upper end surface of the first crescent-shaped rotating block 41, and the other end is rotatably connected to the upper end of the second rotating shaft. A first arc-shaped hole 422 adapted to the second rotating shaft is opened on the secondary crescent-shaped rotating block 42. The second rotating shaft is slidably inserted downward into the first arc-shaped hole 422, ensuring the stability and reliability of the rotation of the secondary crescent-shaped rotating block 42.

[0039] See Figure 1 、 Figure 4 and Figure 5 The surface of one side of the secondary crescent-shaped rotating block 42 close to the third crescent-shaped rotating block 43 is recessed to form a third arc-shaped mating surface 421 that is adapted to the corresponding third crescent-shaped rotating block 43. The third arc-shaped mating surface 421 respectively forms an arc-shaped mating with the surface of the side of the corresponding third crescent-shaped rotating block 43 away from the fourth crescent-shaped rotating block 44. The third crescent-shaped rotating block 43 is respectively installed on the corresponding secondary crescent-shaped rotating block 42 through the third rotating mating piece, thereby ensuring the stability and reliability of the rotation of the third crescent-shaped rotating block 43.

[0040] Among them, the structure of the third rotating matching part is similar to that of the second rotating matching part. The third rotating matching part includes a second connecting block and a third rotating shaft. The second connecting block is arranged in the horizontal direction. One end of the second connecting block is rotatably connected to the upper end surface of the secondary crescent-shaped rotating block 42, and the other end is rotatably connected to the upper end of the third rotating shaft. A second arc-shaped hole 432 adapted to the third rotating shaft is provided on the third crescent-shaped rotating block 43. The third rotating shaft is slidably inserted downward into the second arc-shaped hole 432, ensuring the stability and reliability of the rotation of the third crescent-shaped rotating block 43.

[0041] See Figure 1 、 Figure 5 and Figure 6 The surface of one side of the third-level crescent-shaped rotating block 43 close to the fourth-level crescent-shaped rotating block 44 is recessed to form a fourth-level arc-shaped mating surface 431 that is adapted to the corresponding fourth-level crescent-shaped rotating block 44. The fourth-level arc-shaped mating surface 431 respectively forms an arc-shaped mating with the surface of the side of the corresponding fourth-level crescent-shaped rotating block 44 away from the clamping surface 441. The fourth-level crescent-shaped rotating block 44 is respectively installed on the corresponding third-level crescent-shaped rotating block 43 through the fourth rotating mating piece, ensuring the stability and reliability of the rotation of the fourth-level crescent-shaped rotating block 44.

[0042] Among them, the fourth rotating matching part includes a third connecting block and a fourth rotating shaft that rotates with the fourth-level crescent-shaped rotating block 44.
