For ordinary skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0044] The embodiments of the present application will be described in detail below.

[0045] Embodiments

[0046] In the first aspect, referring to Figure 1 The present embodiment provides an aluminum material, which is hollow, and the aluminum material is divided into a convex part 11 and a wing part 12 by the outward protrusion of the middle part of one side of the aluminum material. The convex part 11 protrudes from the wing part 12.

[0047] The side of the wing part 12 of the aluminum material needs to be drilled, cut and processed.

[0048] In the second aspect, referring to Figures 1-5 The present embodiment provides a processing clamp, which comprises a base 2, a first limiting mechanism 3, a second limiting mechanism 4 and a rotating mechanism.

[0049] The base 2 is plate-shaped and is used for supporting the aluminum material; one end of the base 2 is rotatably connected with a workbench (not shown in the figure) through a rotating shaft 21. The rotating shaft 21 is arranged close to the first limiting mechanism 3 (relative to the second limiting mechanism 4).

[0050] The first limiting mechanism 3 is used for directly or indirectly pressing the wing part 12 of the aluminum material against the base 2.

[0051] The second limiting mechanism 4 is used for directly or indirectly pressing the convex part 11 of the aluminum material against the base 2. The first limiting mechanism 3 and the second limiting mechanism 4 are located on the same side of the base 2, and a gap for accommodating the aluminum material is left between the first limiting mechanism 3 and the second limiting mechanism 4.

[0052] The rotating mechanism is arranged below the base 2 and is used for rotating the base 2 around the rotating shaft 21 to a vertical or horizontal state.

[0053] In use, the aluminum material that has passed the IQC sampling inspection and is stored in the warehouse is transported to the vicinity of the workbench. After comparing the length of multiple (for example, three) aluminum materials, the short material (the aluminum material with relatively short length cannot meet the overall size requirement after processing and cannot be repaired to the qualified size) is rejected. After cleaning the surface of the processing clamp to confirm that there is no aluminum slag or other foreign matter remaining, the aluminum material is placed on the base 2 in a horizontal state. The aluminum material is pressed tightly on the base 2 by the first limiting mechanism 3 and the second limiting mechanism 4. Then, the base 2 is rotated to a vertical state around the rotating shaft 21 by the rotating mechanism, so that the aluminum material is rotated by 90 degrees (as shown in FIGS. 1 and 2), thereby facilitating drilling, cutting and other processing by the cutter 6 movably arranged above the workbench. Figure 3 、 Figure 4

[0054] The first limiting mechanism 3 includes a first mounting seat 31, a first cylinder 32, a first pressing arm 33 and a first pressing block 34.

[0055] The first mounting seat 31 is fastened on the base 2 by screws. The first mounting seat 31 is connected with a first positioning plate 311 which is perpendicular to the first mounting seat 31. After the first positioning plate 311 contacts the side surface of the base 2, the hole on the first positioning plate 311 can be aligned with the hole on the base 2, thereby facilitating the fastening of the first mounting seat 31 on the base 2 by screws.

[0056] The first cylinder 32 is installed on the first mounting seat 31, and the movable end of the first cylinder 32 can be extended and retracted and rotated.

[0057] One end of the first pressing arm 33 is connected with the movable end of the first cylinder 32, and the other end is connected with the first pressing block 34.

[0058] The surface of the first pressing block 34 is smooth, and the hardness thereof is less than that of the aluminum material. In a specific implementation scenario, the first pressing block 34 has a certain elasticity.

[0059] After the aluminum material is placed on the base 2 in a horizontal state, the movable end of the first cylinder 32 is retracted and rotated, driving the first pressing block 34 on the first pressing arm 33 to press on the wing portion 12 of the aluminum material, so that the wing portion 12 of the aluminum material is in direct or indirect pressure contact with the base 2.

[0060] Since the surface of the first pressing block 34 is smooth, and the hardness thereof is less than that of the aluminum material, the aluminum material is not easy to scratch and deform.

[0061] The second limiting mechanism 4 includes a second mounting seat 41, a second cylinder 42, a second pressing arm 43 and a second pressing block 44.

[0062] ​The second mounting base 41 is fastened to the base 2 by screws. The second mounting base 41 is connected with a second positioning plate 411 which is perpendicular to the second mounting base 41. When the second positioning plate 411 contacts the side surface of the base 2, the holes on the second positioning plate 411 are aligned with the holes on the base 2, so that the second mounting base 41 can be fastened to the base 2 by screws.

[0063] The second cylinder 42 is mounted on the second mounting base 41, and the movable end of the second cylinder 42 can be extended and retracted and rotated.

[0064] One end of the second pressing arm 43 is connected with the movable end of the second cylinder 42, and the other end is connected with the second pressing block 44. The length of the second pressing arm 43 is greater than the length of the first pressing arm 33.

[0065] The surface of the second pressing block 44 is smooth, and the hardness of the second pressing block 44 is less than the hardness of the aluminum material. In a specific implementation scenario, the second pressing block 44 has a certain elasticity.

[0066] After the aluminum material is placed on the base 2 in a horizontal state, the movable end of the second cylinder 42 is retracted and rotated, driving the second pressing block 44 on the second pressing arm 43 to press on the convex part 11 of the aluminum material, so that the convex part 11 of the aluminum material is in direct or indirect pressure contact with the base 2.

[0067] Since the surface of the second pressing block 44 is smooth, and the hardness of the second pressing block 44 is less than the hardness of the aluminum material, the aluminum material is not easy to scratch and is not easy to be pressed and deformed.

[0068] The rotating mechanism includes a third cylinder 51, one end of which is arranged at a specified position, and the other end is hingedly connected with the base 2.

[0069] In this embodiment, the aluminum material is in spaced contact with the base 2 in the following manner: a plurality of pads 22 protruding from the base 2 are distributed on the base 2, and the pads 22 are located between the base 2 and the aluminum material to elevate the aluminum material.

[0070] Referring to Figure 2 , further, in order to facilitate positioning of the aluminum material, the base 2 is provided with a side positioning block 23 and an end positioning block 24, the side positioning block 23 is used to contact the side surface of the wing part 12 of the aluminum material, and the end positioning block 24 is used to contact the end surface of the convex part 11 of the aluminum material, so as to facilitate positioning of the aluminum material.

[0071] The base 2 is provided with a hose hole 25, and a binding belt is passed through the hose hole 25 and tied around the air pipe of the first cylinder 32 or the second cylinder 42, so that the air pipe can be limited when the base 2 is rotated.

[0072] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application, and for those skilled in the art, the present application can have various changes and variations, and the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other without conflict. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
