Description
Technical Field
The invention relates to the field of aluminum alloy profile machining equipment, in particular to an automatic feeding device for aluminum alloy profile machining and a working method thereof.
Background
Because aluminum is lighter in weight, and in the building material application field, the aluminum alloy section has the advantage of being convenient for transportation, not only can lighten the workload of installation, but also can quicken the construction progress, and has attractive color, good corrosion resistance, high light and heat reflectivity and good sound absorption performance, and different colors can be easily obtained through chemical action, so the aluminum alloy section is widely used in the aspects of industrial and civil buildings, such as roofs, wall surfaces, ceilings, doors and windows, railing armrests, indoor furniture, market containers and the like.
The right-angle aluminum alloy strip-shaped section is a common standard section, the section shape of the section is L-shaped, and the thickness of the material and the length dimensions of two sides corresponding to the L-shaped section are often different according to different models. In the processing process of the right-angle aluminum alloy strip-shaped section, the right-angle aluminum alloy strip-shaped section is required to be drilled and subjected to attack angles so as to adapt to the subsequent forming and mounting procedures. In the existing production process, drilling is usually carried out manually after the right-angle aluminum alloy strip-shaped section is cut off, in the process of attack angle, measurement and scribing are usually carried out manually, attack angle is completed, even if a feeding device is adopted to be matched with a drilling machine or a punching machine for processing, the processing of the plane of the right-angle side of the right-angle aluminum alloy strip-shaped section corresponding to one side can only be completed, and the other side needs to be clamped again for processing. Therefore, there are disadvantages in that the production efficiency is low, the manpower is wasted, and the machining accuracy cannot be ensured.
In the chinese invention publication No. CN113172258A, a turnover mechanism for positioning and clamping a special-shaped aluminum alloy section is disclosed, which adopts the technical scheme that a second driving assembly is installed on a mounting plate, and a clamping mechanism is installed on the second driving assembly, and the clamping mechanism adopts a rubber block, so that the aluminum alloy section is clamped and positioned by adopting a two-end axial compression method, and it can be seen that the section of the section to be clamped by the clamping mechanism is approximately rectangular, the section area is large and the center of gravity is on the center of rotation, so that the phenomenon that the aluminum alloy section is deviated in the moving process can be approximately ensured by adopting a simpler clamping method of two-end clamping. However, for the rectangular aluminum alloy strip-shaped section with the L-shaped section, on one hand, the clamping is insufficient due to the small contact area, and on the other hand, the gravity center of the rectangular aluminum alloy strip-shaped section is offset in the rotating process, so that the rectangular aluminum alloy strip-shaped section is easy to displace in the rotating or drilling and punching processes.
The application number 201811120051.2 discloses a quick clamping fixture for special-shaped parts, which adopts a positioning base, a first clamping piece and a second clamping piece which are respectively and slidably kept on the positioning base, wherein the positioning base is used for realizing positioning installation with a workbench, and the first clamping piece and the second clamping piece are slidably close to each other under the driving of dead weight, so that the two sides approach and act on the peripheral side surface of the special-shaped part, the peripheral side surface of the special-shaped part is completely positioned and clamped, the circumferential clamping of the special-shaped part is realized, the dead weight locking effect is fully utilized, the advantages of structural introduction and reliable clamping are realized, and the machining quality and the machining efficiency of the special-shaped part are ensured by avoiding loose movement in the machining process. I.e. by using a pair of slides to achieve axial clamping of the profiled element. On the one hand, according to fig. 3 disclosed in the application document of the present invention, it can be seen that the groove cavity structure of the first clamping member for clamping the part is of a semi-closed shape, so that when the shape of the special-shaped part is unchanged and the size is increased, a new clamping member must be replaced to adapt to the clamping function of different sizes. Therefore, the structure cannot be suitable for clamping right-angle aluminum alloy strip-shaped sections with different specifications. On the other hand, the first clamping piece and the second clamping piece slide to be close under the drive of dead weight to realize the circumferential clamping of the special-shaped part, so that when the whole clamp rotates along with the clamped piece, the clamping is loose, even the clamping is completely loosened, and the positioning clamping in rotation cannot be realized.

In addition, corresponding to the adjusting screw 44, a through hole is formed in the inner side wall 402, a positioning boss 441 is formed at the lower end of the adjusting screw 44, a positioning groove 4021 is formed in the corresponding inner side wall 402, a rotating handle 442 is sleeved at one end, far away from the positioning boss 441, of the adjusting screw 44, a step matching surface 4421 is formed on one side, close to the adjusting screw 44, of the rotating handle 442, and the adjusting screw 44 is rotatably mounted on the second protruding portion 42 through the positioning boss 441 and the step matching surface 4421. In this embodiment, the second protruding portion 42 is connected to the disc 41 in a split manner, a boss 422 extends upward from the second protruding portion 42 corresponding to the sliding slot 421, and the step mating surface 4421 contacts with the boss 422. Because the chuck 4 has a complex integral structure, the second protruding part 42 is detachably connected to the disc 41, so that the disc 41 and the second protruding part 42 can be processed and manufactured respectively, and the processing cost is saved. The boss 422 is provided to facilitate mating contact with the step mating surface 4421.
The technical principles of the present invention have been described above in connection with specific embodiments, which are provided for the purpose of explaining the principles of the present invention and are not to be construed as limiting the scope of the present invention in any way. Other embodiments of the invention will be apparent to those skilled in the art from consideration of this specification without undue burden.
